Manual Castings Sandblasting Room Vacuum Sandblasting Chamber Air Sand Blasting For Derusting Remove Paint
Main features:
Sandblasting host:
This set of blasting room uses pressurized blasting machine as the
core unit of blasting system, equipment type: STR-900. The machine
is equipped with two sets of high-efficiency spray guns. It is a
mature technology introduced from Japan's Thick Metro Co., Ltd. It
is characterized by:
A. Compact structure and large amount of sand storage.
B. Safe and reliable, easy to maintain.
C. Mature and stable equipment, less wearing parts
2.1.1 Main technical parameters:
Bore diameter: 900mm
Cylinder height: 2000mm
Full volume: 1m33
Working pressure: 0.5-0.8Mpa Working efficiency: 20-30m2/h/single
shot
Compressed air consumption: >6.3m3/min/gun
Main structure of STR-900 sand blasting machine:
The machine is composed of a sandblasting tank body, a remote
control device, a sand blasting valve, a sand blasting pipe, a gas
supply pipe, a spray gun, a filter and the like.
Principle Introduction:
| No | Comparison item | Honeycomb wind circulation sandblasting room | Traditional mechanical circulation sandblasting room
|
| 1 | Infrastructure
| 0.5-1.2 m or no foundation, low construction cost. . | 2.5-4 m deep pit, high waterproof requirements, foundation construction costs are several times higher than pneumatic recovery.
|
| 2 | Abrasive | Abrasive sorting There is separate sand returning fan. The cyclone separator is used to sort the abrasive. The particle size can be adjusted accurately, and the dust is large.
| There is no separate return sand blower, and the suction pipe is used for vacuuming. The particle size of the abrasive cannot be adjusted, and the air volume of the dust is not easy to be enlarged, and the sprayed abrasive is not uniform;
|
| 3 | The over-all layout | beautiful, the floor space is small, and the installation is convenient. Since all the equipment are connected by pipes, the installation positions of each system can be installed at will according to the site conditions.
| Each transmission system needs to be closely coordinated, it is impossible to change the installation position, the floor space is large, and the maintenance is inconvenient.
|
| 4 | Abrasive accumulation in the sand return system Abrasives | remaining in the sand return system and fewer Abrasives
| remaining in the sand return system, such as screw conveyors, bucket elevators and other equipment will accumulate a large amount of abrasive
|
| 5 | Occupational safety and environmental protection | The overall sand-absorbing and dust-absorbing floor, the wind flow from top to bottom, the dust suppression environment, dust content, visibility, dust emission are better than the national standard.
| Because the underground material needs to be installed with sand conveying equipment, the suction method is generally sucking up. The wind or side suction forms a dusty environment with high dust content, low visibility, and poor working environment.
|
The mechanism consists of:
bucket board, a horizontal auger (spiral), a hoist, a separator,
and a storage bin.
The abrasive falls from the bucket board to the lower auger,
collects into the hoist through the auger, is extracted by the
hoist to the top, enters the separator and falls into the storage
bin, the light dust is sucked into the dust box, and the
backflushing pulse valve takes the filter The dust is blown into
the dust collector.
Auger motor
power3.7kw and hoist power is 3.7kw.
The bucket elevator consists of a cycloidal pinwheel reducer, upper
and lower rollers, conveyor belt, hopper, closed cylinder and
tensioning device. The inlet of the bucket elevator is connected to
the screw conveyor, and the discharge port is connected to the
storage bin. There is an access door on the hoist cover to repair
and replace the hopper. Open the door cover on the lower cover to
repair the lower drive and remove the blockage at the bottom of the
case.
Flat Belt.
In operation, the hopper fixed to the conveyor belt scrapes the
sand at the bottom of the hoist while receiving the sand flowing in
from the transverse auger. Then, driven by the hoist motor, the
sand is conveyed to the top of the hoist, and finally the material
is dropped by centrifugal gravity, and the sand is input into the
spiral of the separator.
In order to ensure that the conveying tape does not slip during
work, the drum is made into a squirrel-cage type, which not only
improves the friction between the lifting tape and the pulley, but
also avoids the slippage of the old-fashioned optical pulley and
reduces the pre-tightening force of the lifting belt. Helps extend
the life of the lifting tape. A set of tensioning devices is
arranged on the upper part of the hoist. When the belt is slack,
adjust the adjusting bolts on both sides of the upper part of the
hoist to tighten the belt.
