Belt filter press for sludge treatment in sand washing plants is suitable for sand washing plants and farms
1. Product features of sand washing sludge dewatering machine:
The ZRDYQ type sand washing sludge dewatering machine is a new type of high - efficiency continuous solid - liquid separationequipment. It uses polyester mesh as the filtering medium and can dehydrate various suspensions with a pre - treated moisture content of less than 99.5 into mud cakes through multi - stage pressing (the moisture content after dehydration varies with different materials). This product is a new generation of belt press filter developed and improved by Shandong Zetray Environmental Protection Technology Co., Ltd. based on the latest foreign sludge dewatering technology and the models of German KLEIN Company, Austrian Andritz Company and French EMO Company. (The dosage of chemicals used in this machine can be reduced by more than 20%).
2. Application scope of sand washing sludge dewatering machine
Renderings of belt filter press for sludge treatment in sand washing plants, suitable for sand washing plants and farms:
This product is suitable for the dehydration of mixed sludge, digested sludge and surplus activated sludge produced by urban sewage; it is also widely used for the dehydration of various types of sludge produced in industries such as gold mining, mining, chemical papermaking, printing and dyeing, leather, electroplating, brewing, coal, and sugar production. Especially, it has a better dehydration effect on activated sludge, gold - mining sludge, flotation concentrates, and tailings (coal).
3. Working process of sand washing sludge dewatering machine
After the sludge is fully mixed with the coagulant, it flows into the feed distributor of the concentration section. The sludge is evenly distributed on the inclined concentration section. Under the bidirectional guiding of the mud rake and the action of gravity, as the filter belt rotates, the free water in the sludge is quickly removed. After gravity dehydration, the concentrated sludge is transported to the gravity dehydration section of the belt filter press through the reversing mechanism for further dehydration. Then it is fed into the "S" - shaped pressing section. In the "S" - shaped pressing section, the sludge is sandwiched between the upper and lower filter cloths and is repeatedly pressed by several rollers of different diameters to dehydrate the sludge again. Finally, the mud cake is scraped off by the scraper, and the upper and lower nets are continuously and automatically cleaned during the operation.
4. Technical characteristics
1. It is mainly used for the treatment of non-concentrated sludge, with the dual functions of concentration and dewatering, saving civil engineering investment. If it is used for dewatering the concentrated sludge, the treatment capacity is significantly higher than that of simple press dewatering, and the dewatering effect is better.
2. Different pore-sized filter belts are used for the concentration section and the press section respectively, and different linear speeds are adopted, optimizing the solid-liquid separation time.
3. The filter belt can be washed with the filtrate, saving the operating cost.
4. The equipment runs continuously with stepless speed regulation.
5. The filter belt is automatically corrected (using pneumatic feedback single-side automatic correction), and the filter belt is pneumatically tensioned with automatic tension adjustment.
6. It is easy to operate, runs smoothly, and is convenient to maintain.
