Brief Introduction
Our business involves petrochemical industry treatment equipment, municipal water affairs, urban sewage treatment equipment, industrial sewage treatment equipment, domestic sewage treatment equipment, pure water equipment, reverse osmosis equipment, water supply purification, waste gas pollution treatment areas.
Product Introduction:
The stacked screw sludge dewatering machine follows the principles of the same direction of power and water, thin-layer dewatering, proper pressure and extension of the dewatering path, which solves the problem of the easy clogging of previous generations of sludge dewatering equipment and the inability to treat low-concentration sludge and oily sewage. Technical problems such as mud, high energy consumption, complex operation, etc., have achieved the goal of high-efficiency and energy-saving dehydration. The dewatering machine can realize high-efficiency flocculation under the condition of fully automatic operation, and continuously complete the sludge concentration and squeezing dewatering work, and finally return or discharge the collected filtrate. It is widely used in municipal sewage treatment projects and water treatment systems in food, starch, oil, pharmaceutical, chemical, paper, leather and other industries.

Structure principle: Stacked screw sludge dewatering machine integrates fully automatic control cabinet, flocculation and tempering tank, sludge thickening and dewatering body and liquid collecting tank in one. The main body is a filtering device formed by stacking a fixed ring and a moving ring with a spiral shaft passing through it. The front section is the concentration section, and the rear section is the dehydration section. The filter gap formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the concentration part to the dehydration part. The screw shaft continuously drives the ring to clean the filter gap to prevent clogging. While the rotation of the screw shaft pushes the sludge from the thickening section to the dewatering section, and under the blocking action of the back pressure plate, a great internal pressure is generated, and the volume is continuously reduced to achieve the purpose of sufficient dehydration.
Selection reference:
Comparison of advantages :
The stacked screw sludge dewatering machine can process oily sludge, can process low-concentration sludge, can operate continuously and automatically, use less water for cleaning, can suppress secondary pollution, and is easy to maintain. The stacked screw sludge dewatering machine produced by our company is a small-volume combined machine with related equipment and control cabinets set on the same base, so the installation is very simple, and because the output power is low, it has the effect of energy saving. The stack screw sludge dewatering machine can be automatically operated by simple operation, and at the same time, it can also be used for unattended continuous operation by selecting the use of polymer flocculant (liquid product) dissolving device; There is no clogging of the machine structure, so there is no problem of recovery cleaning due to reduced capacity, and only the sludge seeping from the dewatering section can be washed.
◆Comparison diagram of stacked screw sludge dewatering machine and traditional dewatering machine◆
1. Widely applicable:
2. Suitable for sludge in municipal sewage, food, beverage, chemical, leather, welding materials, papermaking, printing and dyeing, pharmaceutical and other industries.
3. It is suitable for the dewatering of high and low concentration sludge. When dewatering low-concentration (2000mg/L~) sludge, there is no need to build thickening tanks and storage tanks, which reduces construction costs and reduces the release of phosphorus and the generation of anaerobic odors.
2. Simple design:
1. Compact design, the dehydrator contains an electric control cabinet, a metering tank, a flocculation mixing tank and a dehydrator main body.
2. It occupies a small space and is easy to repair and replace; it is small in weight and easy to carry.
3. Not easy to be blocked:
1. It has the function of self-cleaning. There is no need to clean in order to prevent clogging of the filter, reduce the amount of flushing water and reduce the burden of internal circulation.
2. Good at dewatering oily sludge.
4. Low speed operation:
1. The rotation speed of the screw shaft is about 2~3 revolutions per minute, with low electrode consumption.
2. Few failures, low noise and vibration, safe operation.
5. Simple operation:
1. Through the electric control cabinet, it is linked with the bubble machine, the mud pump, the dosing pump, etc., to achieve continuous unmanned operation for 24 hours.
2. The daily maintenance time is short and the maintenance operation is simple.
6. Durable:
1. Almost all the machine body is made of stainless steel, which can maximize the service life.
2. Only the screw shaft and the moving ring are the replacement parts, and the service life is long.
