and product introduction,

Upholding the quality first

The area which our company involved is including the shot blasting machine,

core shooter, sand mixer, environmental protection equipment, fan, wear-resistant

material and steel shot,etc

This machine is mainly composed of cleaning room, blast wheel, pneumatic lifting door,

Pneumatically controlled abrasive gate valve, Pneumatic control system, automatic

loading and unloading system, elevator, screw conveyor,separation system,electrical

system and other parts.

We use Swedish imports (HARDOX HD600) for the material of the shot blasting room

guard and the door guard.The wear resistance is good, which saves a lot of maintenance

costs and man-hours, and achieve maximizes benefits.

Steel belt is connected by track shoe, and the material is wear-resistant high manganese

steel. The two ends of the track shoe are bolted to a chain link. The chain link is made of

carburized and hardened surface of 20CrMnMo alloy steel, and the chain link is connected

by steel pins. The driving device (3kw motor direct connection type) forces the steel belt

to run by chain drive. The two ends of the track cavity are equipped with end plates made

of steel plates, and wear plates are installed inside the end plates. Bearing housings

mountedoutside the chamber wall should be sealed and filled with grease to support the

end discs. The end plate can be adjusted in various directions.Reinforcement ribs are

fixed on both sides of the room to prevent deformation of the room.

After years of research and development and technical cooperation with German

companies, the company has manufactured a high-power direct-connected curve type

7.5-75Kw high-efficiency blast wheel, breaking the monopoly of high-power direct-connected

blast wheel technology in Europe and America. The blast wheel is a key component in

various shot blasting equipment, and is widely used in the surface cleaning and pretreatment

of castings, forgings, welding parts, heat treatment parts, and surface strengthening

processes of gears, spring sand other mechanical parts. This blast wheel technology is one

of the important advances in the development history of China's blast wheel.

The blast wheel also has the following characteristics:

After adding a specified number of workpieces in the shot blasting chamber, the pneumatic

door is automatically closed, the machine is started, the workpiece is driven by the drum,

and it starts to flip.At the same time, the abrasives thrown out by the blast wheel form a

fan-shaped beam, which evenly strikes the workpiece surface.The thrown abrasives and

grit flow from the small holes on the steel belt into the screw conveyor at the bottom,

and are conveyed into the elevator, which is transported by the elevator to the separator

for separation. Dust-containing gas is sucked into the dust collector by the fan for filtering,

and then becomes clean air, which is discharged into the atmosphere. The dust is blown

back into the dust collection box at the bottom of the dust collector by air, and the user can

remove it regularly. Waste sand flows out of the waste pipe and can be reused.The shot

and sand mixture is recovered into the chamber through a recovery tube, and reused after

the separator is separated;the clean abrasive enters the blast wheel through the abrasive

gate and throws the workpiece.

This machine is composed of shot blasting room, blast wheel assembly, abrasive recycling

system, automatic loading system, steel belt system, dust removal system and electrical

control part.

This machine is a small cleaning equipment, which is mainly composed of cleaning room, shot blasting assembly, elevator, separator, electrical system and other parts. See Figure 1 (Table 1 indicates the name corresponding to the serial number of each part) Working principle: Add a specified number of workpieces in the cleaning room. After the machine is started, the projectiles thrown by the shot blaster at high speed will form a stream of shots, which will evenly strike the surface of the workpiece to achieve the purpose of cleaning and strengthening. The thrown projectiles and sand particles flow into the elevator and are lifted by the elevator to the separator for separation. The dust is sucked by the fan and sent to the dust collector to be filtered. The clean air is discharged into the atmosphere. The dust on the cloth bag is mechanically shaken and falls into the dust box at the bottom of the dust collector. The user can clean it regularly. The waste sand flows out from the waste pipe. Can be reused. The shot-sand mixture is retracted into the chamber by the reuse tube, and is reused after the separator is separated. The clean shots enter the shot blasting device through the electromagnetic supply gate to throw the workpiece.

Machine operation: 1. Only if you have a comprehensive understanding of the working principle, performance, operation method, lubrication and other aspects of this machine, you can operate it; 2. Put the projectiles (200kg) into the chamber one after another, then put them into the workpiece, close the feeding door, and prepare to drive; 3. Start the dust collector fan; 4. Start by pressing the buttons in turn: hoist, shot blasting device, and shot supply gate to start cleaning. After the cleaning is completed, turn off the buttons in turn: the pill supply gate, shot blasting device, elevator, dust collector fan, and then start the rapping motor to clean the dust, and the rapping will stop after a certain period of time; 5. After the shot blasting machine is completely stopped, open the feeding door and lift the tooling and workpiece out. 6. In case of emergency, press the emergency stop button and the machine will stop working immediately; 7. After all the work is completed, the dust collector should be turned off in time; 8. In the ventilation and dust removal system, there are two butterfly valves (see the dust removal system diagram). Adjust the two butterfly valves according to the situation to get a good separation effect; 9. Adjustment of the directional sleeve of the shot blaster: The adjustment of the directional sleeve can refer to the schematic diagram shown in Figure 4. 10. The shot blasting machine has three types of ejection speeds. When the ejection speed needs to be changed, it can be completed by changing the belt pulley of the shot blasting machine motor. The replacement steps are as follows: First, turn off the shot blasting device and the main power supply. After the shot blasting device is completely stopped, loosen the motor fastening bolts, remove the V-belt, and then use a hexagonal wrench to loosen the pulley fastening bolts. Use three M12 bolts to tighten the cone The shaft sleeve is separated from the belt pulley, and the belt pulley is removed. Fit the required pulley with the tapered bushing, press it into the motor shaft, and then tighten the three M10 pulley fastening bolts with a hex wrench. Put on the V-belt again, and finally, push the motor to a suitable position with a jack wire, and tighten the bolts to fasten the motor. Note: The outer end surface of the motor pulley should be on the same plane as the outer end surface of the shot blaster pulley. Otherwise, loosen the three M10 pulley fastening bolts for adjustment. The three projecting speeds correspond to the lifting capacity of the two hoists, and the installation and adjustment methods of the hoist motor sprocket are the same as above. The corresponding relationship between the three projecting speeds and the diameter of the pulley and sprocket is as follows:

Ejection velocity 75m/s 80m/s 85m/s

Pulley diameter 131mm 141mm 151mm

Sprocket diameter 179mm/28 teeth 136mm/21 teeth 136mm/21 teeth.

11. This machine has a manual pill gate. In normal operation, the manual pill gate is in the state of supplying pill and discharging off. At this time, the electromagnetic pill supply gate is supplied with pill material. When you need to unload, just turn the handle of the manual pill gate to the opposite position to unload. Note that whether it is unloading or feeding pills, the handle should be fixed in the corresponding position with a fastening bolt. 12. After using the machine for a week, open the access door at the lower part of the front of the chamber in time to remove large pieces of material on the screen, check the wear of the screen, and replace the screen in time. (2) Matters needing attention: 1. The dust in the dust box under the dust collector should be removed regularly to prevent the dust exhaust pipe from being blocked and affecting the dust removal effect; 2. The debris under the screen in the bottom of the cleaning room and the separator funnel should be cleaned frequently; 3. The projectiles around the equipment should be cleaned frequently to prevent slippage and injury; 4. Frequently check the track and hoist belt in the cleaning room for deviations, so as not to damage the belt; 5. It is forbidden to open the feeding door when the shot blasting machine is not completely stopped to prevent accidents. 6. Maintenance and maintenance of the machine 1. After each work shift, the machine should be cleaned again; 2. The guard plate in the cleaning room, the directional sleeve in the shot blasting device, the blasting wheel and other wear parts should be checked frequently. If the wear is serious, they should be replaced immediately; 3. Lubricate regularly as required, and check whether the machine is flexible. The equipment lubrication points are shown in Table 2; 4. Regularly check the transmission parts, clean the parts, and replace the worn parts; 5. When the machine is inspected and maintained, the power must be cut off to avoid accidents; 6. The wear protection plate of the cleaning room can be replaced regularly according to the wear condition. When replacing the guard plates, the installation gap between the guard plates should be controlled within 2 mm.
