Problems solved by technology

At present, sludge dehydration and sand removal are mostly manually sieved with sieves on site, which is labor-intensive, low-efficiency, incomplete sand sieving, easy to cause waste, and difficult to guarantee quality
[0003] With the development of mechanical equipment and the promotion of applications, various mechanical sludge dewatering and sand removal equipment have emerged one after another. At present, the structure of the sludge dewatering and sand removal machine is equipped with a frame, which is equipped with a feeding mechanism, Screening mechanism and conveying mechanism, this kind of sludge dewatering and sand removal machine needs to be pulled by external force when changing the working position, which is time-consuming and laborious, and the production efficiency is low
In addition, the electric sludge dewatering and sand removal machine on the market includes a frame, a sand dredging mechanism, a transmission mechanism, and a vibrating screen. The vibrating screen is installed behind and below the transmission mechanism. The sludge is not easy to transport, and the machine is bulky, complex in structure, cumbersome in operation and inconvenient to use

Background technique [0002] Sludge is a kind of common waste. The quality of sludge dewatering and sand removal directly affects the subsequent processes. The impurities and stones in the sludge must be filtered out before the subsequent processes are used. At present, most of the sludge dewatering and sand removal is manually sieved with a sieve on site. The labor intensity is high, the work efficiency is low, the sand screening is not thorough, it is easy to cause waste, and the quality is difficult to guarantee. [0003] With the development of mechanical equipment and the promotion of its application, various mechanical sludge dewatering and desanding equipment have appeared one after another.
