What should the screw press dehydrator pay attention to when cleaning up the residue?

After the screw press dehydrator completes the pressing process, the liquid in the material will be collected from the filter screen and other parts, and the residue cannot be completely discharged, and the next step of inspection and treatment is required.

1. When the screw press dehydrator is not in use, check whether the inside of the machine is clean, such as whether the filter belt is stuck and whether the filter belt is cleaned frequently.

2. Before opening the device, check for damage. Residue and damage can affect the proper operation of the device. Therefore, in this case, it is necessary to clean up debris and replace damaged parts.

3. The chassis is a device for discharging the liquid in the processed material, so it must be checked whether it is unblocked or blocked.

Reasons and solutions for non-parallel screw press dehydrators:

1. The installation position of the tension roller is incorrect. It is necessary to check and calibrate the horizontal and parallel directions of the tension. The correction method and error value are the same as above.

2. The support bearings on both sides of the tension roller are faulty, and the inspection and maintenance of the bearings should be strengthened during operation.

3. When the tension roller is out of sync, it is easy to cause tension cylinder failure and synchronous gear wear. It is necessary to strengthen the inspection and maintenance of the synchronous gear, tension cylinder and its auxiliary pneumatic pipe fittings.

4. The offset of the tension rod mainly occurs when the tension rod sleeve is damaged or falls off too much, the wear degree of the sleeve should be checked regularly, and maintenance and replacement should be arranged in time

5. The roundness and coaxiality of the tension roller should be checked for accuracy before installation, and the tolerance value is the same as above.

Introduction to the working principle of the screw press dehydrator:

The feeding screw directs the material entering the material box towards the extrusion screw. The tooth pitch of the extrusion screw is reduced, and the shaft diameter is enlarged. Under the action of the friction resistance of the screen wall and the cone, the liquid contained in the material is kneaded and formed. The liquid will be eliminated with the sieving equipment and concentrated somewhere.

The squeezed pomace exits the main machine through the end of the screen drum and the center of the cone. The rear side of the cone is provided with a spring. After maintaining the torque force and direction of the spring, the frictional resistance and size of the discharge port can be adjusted to maintain the level of the wet area of extrusion. The squeeze dehydrator can also be used for solid-liquid separation of other materials, and its effect varies with the quality of the material.

When using the screw press dehydrator, you must pay attention to safety and use it in the correct way to avoid losses caused by wrong operation methods.
