Shaftless screw conveying and pressing machine Chongqing Wolik Environmental Protection Equipment Co., Ltd.
Shaftless screw conveying and compacting machine (also known as shaftless screw conveying compactor) is an integrated device for conveying and squeezing dewatering grid slag in the sewage treatment process. Enter the slag bucket or garbage truck to facilitate the transportation and disposal of grid slag.
The structure is simple, the floor space is small, and the installation and maintenance are convenient. Except for the inlet and outlet openings, the other parts can be covered and sealed to prevent the materials from overflowing and reducing air pollution.
Construction and working process:
The screw press consists of an extrusion screw, a spiral tube, a transmission part, a feeding hopper and a discharging hopper. The dirt enters the spiral tube from the feeding hopper, and is conveyed to the slag outlet after being compressed and dehydrated under the action of the extrusion screw.
Screw conveyor presses are suitable for urban sewage treatment plants, residential community sewage pretreatment devices, municipal rain / sewage pumping stations, and water plant beer lees; bean dregs; potato dregs starches, mainly suitable for paper pulp, animal manure, slaughter sludge , Lees, fruit, biogas digester, canteen dewatering and other materials, especially for dehydration and recycling of materials rich in plant fiber, the effect is better.
For juice extraction and dehydration operations containing certain fiber materials, such as fresh grape skin residues after juice separation or fermentation of grape skin residues, sea buckthorn fruit, aloe, ginger and other fruits and vegetables; fermented lees and cassava residues Dehydration of corn cob residue, Gynostemma pentaphyllum, Stevia, Chinese cabbage, uranium grass, celery, Chinese medicine residue, chrysanthemum, etc .; use wood, wheat straw, straw, reed, etc. as raw materials to produce fully chemical pulp and semi-chemical pulp Extraction of black liquor and dehydration after washing. At the same time, it is also widely used in sludge dewatering and garbage treatment. In particular, it can separate poultry and animal manure water into liquid organic fertilizer and solid organic fertilizer. Liquid organic fertilizers can be directly used for crop utilization and absorption. Solid organic fertilizers can be transported to fertilizer-deficient areas and used to improve soil structure. At the same time, they can be made into organic compound fertilizers through fermentation.
1. The driving device adopts a shaft-mounted parallel shaft helical gear reducer, which has a compact structure and safe translation.
2. Spiral blades are welded on the spiral shaft, which enhances the blade's rigidity and crushing ability. The spiral blade adopts variable pitch open type.
3, the discharge pipe and the press cylinder at an angle of 45 degrees
4. The press frame is fixed with expansion bolts, no embedded parts are required.
5. The equipment can be controlled online with supporting equipment, which is convenient to control, and can also be equipped with a local control box by itself.
