Exporting Sludge Dryer Machine Vacuum Rake Rotary Drum Paddle Dryer
1. Check whether all parts of Hollow paddle dryer are installed properly. Does the lubricating oil added by the reducer meet the requirements of the reducer? Turn the motor fan impeller to check whether the blade shaft and the wall of the tube are not rubbed, the inlet is unblocked, and the inlet is clear. The material port is closed, etc.
2. Cover the motor impeller hood and start the motor to run dry. The blade rotation must meet the specified requirements. The blade runs without any abnormality, vibration and noise. During the gap operation, the feeding amount is limited to the submerged blade of the material, and the material valve is discharged after the specified time is reached.
3. The inlet valve and the condensate drain valve must be slowly opened under the rotation of the blade shaft. The steam should be slowly introduced into the jacket and the blade shaft for a period of 30 minutes or more. The pressure reducing valve and the safety valve must not be adjusted. Exceeding the rated pressure. The wet material can be evenly fed into the dryer under the condition that the steam pressure meets the specified requirements and the equipment is operating normally.
4. When the hollow paddle dryer is working, it is strictly forbidden to entrain the blocky hard material in the wet material to prevent the blocky hard object from getting stuck between the blade and the cylinder, damaging the blade or the cylinder, causing damage to the equipment. . During continuous operation, the amount of charge is controlled so that the host current does not exceed 70% of the rated current.
The Hollow Paddle Dryer has a metal wall which separates the process mass from the heat source (steam or hot oil). High thermal efficiency is obtained because the heat from the thermal medium goes directly into the process mass. As the material comes into contact with the heated through and agitators, the process mass is heated via conduction. With an insulated dryer, very little heat is lost. To evaporate 1kg of water only requires about 1.2kg of steam for slurry materials. Exhaust gas is minimal and at a low temperature. Therefore, the volume of non-condensable gas from the dryer, which might require treatment, is minimal.
The dryer is an indirect heat transfer device which utilizes a high degree of mechanical agitation to enhance contact with the product being dried. Evaporation rates per square foot of heat transfer surface are maximized through self-cleaning paddles and the mixing effect. Movement of the process material between the slanting surfaces of the revolving wedge-shaped paddles generates shearing forces, which clean the paddle surfaces and maximize conductivity. Counter rotating shafts move the material away from the walls, cleaning the walls by means of the tab on each paddle. This results in higher heat transfer rates than disc or single shaft designs.
The wedge-shaped paddles, and the intermeshing of the dual agitators, create a localized mixing effect around the paddle. This allows more individual particles in the bed to be exposed directly to the heat transfer surface, thereby increasing the heat transfer rate, allowing the use of smaller equipment.

1) Low energy consumption: As a result of indirect heating, no much air take away the
heating, the outer wall has insulation layer, the heat efficiency
can be up to 90%. For slurry, evaporating 1kg of water just need 1.2kg vapor.
2) cheap investment: it has huge effective heat transfer surface area per unit, reduce treatment time,
let the machine size become small, so It greatly reduces the
construction area and building space.
3) wide range of materials handling: can use different types of media, not only can treat
heat-sensitive materials, but also handle high-temperature
materials. Common medias are: water vapor, thermal oil, hot water,
cooling water and so on.
4) flexible operation method: Can be continuous operation or intermittent operation, can be
applied in many fields.
5) Low environmental pollution: don't use air to dry material, dust material entrainment is rare.
Small solvent evaporation, easy to treat. For contaminated
materials or solvent recovery conditions, closed-loop can be used.
6) Cheap operating costs: Low-speed mixing and reasonable structure, Low wear, low
maintenance costs. For normal operation, just only 1 person / day.
7) Stable operation: Due to the special compression-expansion stirring of the wedge
blades, the material particle contact with the heat transfer
surface enough, it ensure the processing is stable.
