Product Description
A screw press is a machine that uses a rotating screw to press sludge against a permeable filter to drain water and produce a dry sludge cake.
The screw press is composed of a screw stacking body, a driving device, a filtrate tank, a flocculation tank, a frame, etc. The stacked screw body is composed of a fixed ring, a movable ring, a screw shaft, a screw, a gasket, and a connecting plate. The fixed rings and the movable rings are stacked on each other, and the screw shaft runs through it to form a filter body. It can be used in biochemical pharmaceuticals, petroleum refining, power plant wastewater, municipal wastewater, brewing wastewater, coal washing wastewater, chemical wastewater, printing, and dyeing paper making, and food industries.
2. Dehydration: The concentrated sludge moves forward continuously with the rotation of the screw shaft; along the direction of the mud cake outlet, the pitch of the screw shaft gradually decreases, the gap between the rings also gradually decreases, and the volume of the screw cavity Continuous shrinkage; under the action of the back pressure plate, the internal pressure gradually increases, driven by the continuous operation of the screw drive shaft, the water in the sludge is squeezed out, the solid content of the filter cake continues to increase, and the continuous dehydration of the sludge is realized.
3. Self-cleaning: The rotation of the screw shaft drives the moving ring to rotate continuously. The equipment relies on the movement between the fixed ring and the moving ring to realize a continuous self-cleaning process, avoiding the clogging problem of the traditional dehydrator.

Various types of products, exquisite design, small footprint.
Compared with the traditional belt type, plate frame, and centrifugal dewatering machines, the screw press adopts the three-in-one design of the dehydration body, the flocculation mixing tank, and the electric control device, which is portable to install and occupies a small space, greatly reducing the design and construction cost. At the same time, there is no need to re-construct the replacement project due to the exquisite design of the stacked screws.Simple operation and maintenance.
The 24-hour fully automatic unmanned operation can be realized through various methods such as PLC remote control, reducing operator's employment and maintenance costs. At the same time, due to its exquisite design, it is easy to learn and operate.
Water saving, power saving, low noise.
The screw press has a self-cleaning function and does not require a lot of cleaning water for clogging. Compared with other dehydrators, the flushing water consumption of the screw press is one percent of that of the belt dehydrator. The rotation speed of the screw shaft is 2-5 revolutions per minute, and the power consumption is low, which is economical and applicable. At the same time, due to the low speed and intermittent flushing, the equipment runs without noise.
Municipal and sewage treatment: Most of the sewage from municipal sewage plants comes from urban domestic sewage, in which the content of organic sludge is high. The screw press dehydrates well, has low energy consumption, and can run unattended all day, so the screw press is suitable for municipal sewage factories.
Printing and dyeing enterprises: The pollutants in the sewage of printing and dyeing factories are complex. The water quality of this kind of sewage changes greatly, and the content of organic sludge is also relatively high. However, the screw press is used to deal with this kind of dye and fiber impurities. The dynamic and static ring pieces for the screw press Instead of the traditional filter cloth, there will be no clogging.Papermaking and tobacco enterprises: The sewage produced by papermaking and tobacco has a large proportion of plant fibers and detergent additives. Among them, the water of pulp and cut tobacco is relatively alkaline, which is easy to corrode the machine and accumulate mud. With self-cleaning function, no residue left, and longer service life.
Beer and fruit juice enterprises: Wastewater mainly contains fruit peels, additives, fibers, carbohydrates, and alcohol. Due to the high content of organic matter, it is easy to become rancid and fermented. The screw press is relatively easy to treat juice beer sewage. The machine is made of 304 stainless steel, which is wear-resistant and anti-corrosion and is more suitable for juice brewery applications.
Starch and pharmaceutical companies: The wastewater produced in the process of starch and pharmaceuticals contains a lot of small molecule organic matter and is easily soluble in water. The screw press realizes the overall completion of flocculation and dehydration, ideal mud output, and relatively clear discharged water.
