Screw press is more and more widely used at this stage, especially in the fruit and vegetable pressing production and processing industry. Screw dehydrator is a dehydration equipment with good dehydration effect at present, which can be pressed step by step without returning materials, deviation, high efficiency and rapid drying. In addition, the screw dehydrator can not only be used as a solid liquid separation equipment for waste dehydration or mixture reduction, but also as a juice extractor for vegetables and fruits.

The screw press is inseparable from wastewater and sludge in the whole operation process. These two compounds are very harmful to the bearing. The selected bearing should be wear-resistant. Besides sealing, lubrication should also be in place, as shown below.

1. If the bearing is damaged, replace it immediately. When installing new bearings, they must be standardized Be careful not to lose it. Avoid damaging bearings and printing pressure Split.

2. During the whole process of using mechanical equipment, pay attention to the anti rust treatment of bearings, and do not touch too much water. Clean the area around the bearing pedestal and apply lubricant for maintenance.

The screw press is a solid liquid separation equipment for extruding and dewatering of various waste residues, which is composed of a feed bin Press screw type, screw seamless steel pipe, slag discharge pipe and controller equipment. The slag to be treated enters the spiral seamless steel pipe from the feed bin and is extruded and dried under the action of the extrusion screw. The water extruded from the raw materials is gathered into the stainless steel water tank through the filter screen and discharged through the sewage pipe. After the raw materials become smaller, they are discharged through the slag discharge pipe, which greatly reduces the net weight and capacity of dirt such as grid slag. The screw press consists of sewage pipe area, feeding area, screw transport area and feeding area. The grid slag enters the feeding area, and is compacted in the compaction area according to the screw press. The grid slag is discharged, and the sewage is introduced into the seepage pipe from the grid bar.

Application features of screw press:

1. The screw press is not afraid of wearing the complex materials of biogas residue, and the water is discharged smoothly. The purpose of squeezing and separation is achieved by the effective cooperation of screw and screen.

2. The frame screw press has successfully solved the problem of screen plugging. Its core technology is the cooperation between the screw and the screen mesh to realize the self-cleaning function of the screen mesh, that is, to achieve interaction with the screw through special devices, mix materials, avoid material shafts, and realize that material particles can wipe off the screen mesh blockage in the process of screw forward.

3. The control of the tail cone is different from the common spring, hydraulic pressure and hand wheel in the market., The pneumatic device with very low maintenance cost is adopted to effectively realize the "back pressure" control of material pressing through specific design, that is, after a certain extrusion pressure is set, the device automatically controls the extrusion pressure of materials to avoid the dryness and wetness of slag. The extrusion separator adopts the principle of superposition compression. The screw compressor is especially suitable for assembly line operation, avoiding the shortcomings of centralized processing of ordinary compressors.

4. The special angle design of the feeding box of the screw press can effectively prevent the "bridging" of some viscous materials. Although it is a small detail, once the "scaffolding" is not produced on the production site, it will lead to the shutdown without feeding, which is very troublesome, so the details determine the success or failure.
