Before operating the screw press, a simple experimental treatment can be carried out to confirm that there is no problem and large-scale treatment can be carried out continuously. However, special attention should be paid to selecting a suitable distance stage and sampling according to the specified amount. After the application of the screw press, special attention should be paid to cleaning the equipment. If there are many residues inside, try to clean it with resin solvent. During cleaning, special attention should be paid to the maintenance of rubber alienation. During cleaning, special attention should be paid to the internal conditions of the equipment, which is also beneficial to the long-term application of the screw press and ensures our rights and interests.

It is recommended that we should see whether the equipment has self cleaning function when it is used. Many intelligent devices have cleaning function, so daily cleaning is also very simple.

In addition to cleaning the screw press, the equipment should be strictly inspected every once in a while. During daily use, workers should be encouraged to continuously investigate the equipment to see if there are any problems and abnormal noises. If problems are found, they should be handled in time to prevent larger problems.

At present, there are two kinds of sludge treatment methods commonly used in the country. One is the natural drying method, which makes the sludge rely on infiltration and evaporation to reduce the water content of the sludge. However, this method is not suitable for most regions due to the hazards of weather and humidity. The other is the mechanical dehydration method, which is sufficient dewatered sludge, which is equivalent to the original flow state. The concentrated or digested sludge is dehydrated and converted into semi-solid or solid sludge. There are also many mechanical equipment for sludge dewatering. The screw press evenly adds high humidity sludge from the feed box, moves the axial feed end under the drive of the screw blade, and carries out mechanical sludge dewatering under the huge pressing force of the variable pitch, screw and adjusting baffle. The water is discharged to the outlet through the screen, and the dewatered sludge is discharged to the discharge box. According to the adjustment of screw type sludge extrusion dehydrator, it can change different material varieties and production capacity, so as to achieve good dehydration effect and production cooperation.

The screw press is the requirement of our company for the dehydration of high wet waste materials. It has the distinct characteristics of continuous production, high efficiency, low energy consumption, low noise and convenient operation and maintenance; The working content of the screw press: after the electromagnetic speed regulating motor operates normally, the materials are uniformly added from the feed box. The feed moves forward along the diameter under the screw drive. The material is subject to the change of tooth distance and the adjustment of the transmission during the forward movement, which generates a large extrusion phase interaction force, so that the material can be continuously dehydrated under the external force. From the feed port to the spiral dehydrator, the diameter of the dividing circle of the spiral guide roller decreases from width, and the blade groove of the guide roller weakens from depth, so that the working pressure of the material in the extrusion movement gradually increases, and the material liquid is separated according to the stainless steel separation network. The separated liquid is discharged from the bottom of the generator set and the outlet inside the guide roller, and the extruded material is discharged from the feed port.
