how to clean screw conveyor residual material?

screw conveyor conveys the material through the spiral piece, so that the material does not rotate together with the screw conveyor blade is the friction resistance of the material's own weight and the screw conveyor shell to the material. For the spiral blade welded on the rotating shaft of the screw conveyor, the surface type of the blade can be divided into solid surface type, belt surface type and blade surface type according to the different conveying materials. Before using the screw conveyor, the user must pay attention to check whether there are sundries in the casing, so as not to affect the production and use. If you do not pay attention to cleaning, if there is a large amount of material in the equipment, it is easy to cause the equipment to be overloaded and even burn the motor. Screw conveyor is a kind of efficient conveying equipment, after the use of the equipment will inevitably have a certain amount of material can not be completely discharged, then to clean up after the shutdown, prohibit the equipment has not been completely stopped to clean up, in order to avoid accidents. Because the screw conveyor has two common design methods, tube type and trough type, the cleaning method is also different.

before starting the machine. The equipment must be checked before starting up to prevent foreign matter from falling into the conveyor, causing damage to the spiral disc or fracture of the spiral shaft. Then clean the inside of the equipment.

1. The tubular screw conveyor is also called the screw feeder. Since the casing is a steel pipe, there are two methods for cleaning, flushing with water or ventilating. Water injection cleaning means that a large amount of water is introduced into the flushing pipe at the feed inlet to flush out the remaining materials. Ventilation cleaning is to use an air pump or fan to pass a large amount of air into the pipe and blow the material out of the pipe body. These two methods can be very convenient to clean the material in the tube.

2. The casing of LS series groove screw conveyor is U-shaped groove, and there is a cover plate on the groove body. During cleaning, the fixing bolts can be removed, the cover plate can be removed, and then cleaned. This type of conveyor is more convenient to clean, and can be directly cleaned with air pump, etc.

Cleaning of residual materials in the screw conveyor is an important step in equipment maintenance. This equipment is mainly used to transport some small pieces, powder and granular materials. If it is not cleaned in time, the materials will remain inside the body. The equipment is easy to cause excessive load when starting up. Moreover, if the conveyed materials have large particle size, it is easy to damage the screw blades and even burn the motor.

In addition, the internal cleaning can also be attached to the screw shaft and the blade of the material to clean up. And can prevent the material into the middle of the hanging bearing. As we all know, hanging bearings are used in screw conveyors with long conveying distances. If hanging bearings enter a large amount of materials, it is easy to cause bearing damage and even screw shaft fracture. Therefore, the user needs to clean the equipment in time after use.
