Wuchang environmental protection intelligent stacked screw dewatering machine is an economical, environmentally friendly and efficient sludge dewatering equipment. It is mainly composed of five parts: automatic intelligent control cabinet, pharmaceutical preparation and stirring device, concentration and dehydration host, liquid collection device, and mud diversion device. Under the condition of automatic and intelligent operation, it can realize flocculation dosing, stirring and pre-mixing, and Continuously complete the sludge concentration and squeezing dewatering work, and return the collected clean filtrate to resource utilization or discharge treatment.

The stacked screw dewatering machine uses the principle of screw extrusion, through the strong extrusion force generated by the change of the screw diameter and pitch, and the tiny gap between the moving ring and the fixed ring, a new type of solidification for squeezing and dewatering the sludge is realized. Liquid separation equipment. The Wuchang stack screw dehydrator has the advantages of anti-wear, no pollution, low energy consumption, simple operation, and high degree of intelligence. It achieves the goal of high-efficiency and energy-saving dehydration, can reduce the number or volume of sedimentation tanks and sludge thickening tanks, and save sewage Deal with the construction cost of the plant.

Working principle of snail dewatering machine:

The main body of the screw dewatering machine is a sludge filtering device formed by stacking a fixed ring and a moving ring with a screw shaft penetrating through it. The front section is a concentration zone, and the rear section is a dehydration zone.

When the spiral dewatering machine is running, the sludge enters from the sludge inlet and is pushed by the screw shaft. The sludge is gravity concentrated in the thickening zone and then transported to the dewatering zone to achieve full dehydration. When the screw shaft of the screw dehydrator rotates and pushes, it drives the moving and static ring pieces around the circumference of the screw shaft to move relative to each other, so as to continuously drive the ring pieces to move up and down, left and right to clean the gaps and prevent clogging. The small movable gap formed between the filtrate is used to filter the filtrate, so that the filtrate can be quickly filtered out in the gap of the relatively moving ring sheet. The inner cavity formed by the screw shaft and the ring sheet is filled with flocculated particles. Using the pitch of the screw shaft and the gap between the ring sheet and the ring sheet, the volume of the spiral cavity is continuously tightened and compressed by rotating and pushing, and the volume of the inner cavity is continuously reduced. Under the action, the pressure in the inner cavity increases continuously, and the water content of the mud cake is continuously reduced by adjusting the pressure plate. Under the continuous thrust of the screw shaft, the filtrate is continuously separated and discharged, and the mud cake is discharged after the sludge is dehydrated. The rotation process of the back pressure plate at the end conveys the extrusion and forms a mud cake.


Features of Wuchang Stacking Screw Dewatering Machine:

1. Good at processing oily sludge:

Compared with the traditional sludge dewatering machine, the self-cleaning and cleaning structure of the snail dewatering machine is not easy to cause clogging of the filter gap, and even oily sludge can be easily processed.

2. Intelligent control system:

Set up a one-key start and stop function, automatic mud, automatic water, automatic feeding, self-induction detection and alarm, can be fully automated and unattended operation for 24 hours, to achieve manual-free.

3. Compact design and space saving:

Compared with the traditional sludge dewatering machine, the dewatering body, flocculation and stirring tank and intelligent electric control cabinet of the sludge dewatering machine adopt an integrated design, which is convenient to install, simple to operate, small in footprint, and compatible with auxiliary equipment. , Easy to replace the original old equipment.

4. Power saving and low energy consumption:

The screw shaft is the core component of the screw dehydrator, and its speed is 2-4 revolutions per minute. Due to the low-speed rotation, the power consumption is very small. Under the same processing capacity, the power consumption of the spiral dehydrator is only one twentieth of the belt dehydrator.

5. Water saving and operating cost:

The self-cleaning structure of the screw dehydrator body to prevent clogging of the filter slot can save a lot of cleaning water. Under the same processing volume, the water consumption of the screw dehydrator is only about one-120th of that of the belt dehydrator.

6. Wide application range:

Suitable for oily sludge, oily wastewater, oil fields, natural gas fields, petrochemicals, municipal sewage, tap water, industrial wastewater, food, beverages, animal husbandry, machinery manufacturing, metal processing, biopharmaceuticals, leather, printing and dyeing, washing, papermaking, etc. The sludge dehydration treatment process in this industry.
