Backflushing type sediment separation device

Abstract

The invention discloses a backflushing type sediment separation device. The device comprises an outer cylinder, an inner rotating cylinder, a propeller, a supporting frame, a brush cylinder, a separation kettle, a sand separator, a pump set and a control device, wherein the outer cylinder is fixed on the supporting frame, the inner rotating cylinder is rotatably fixed in the outer cylinder, the brush cylinder comprises a cylinder body and a scrubbing brush, the top end of the cylinder body is fixed on the propeller and is driven by the propeller to move horizontally, the sand separator comprises separation motors, separation support plates, drawing ropes, filter cloth, fixed pulleys and pulley yokes, the plurality of separation support plates are fixed on the outer wall of the separation kettle in a surrounding manner, the separation motor and the pulley yoke are fixed on the top surface of each separation support plate, the fixed pulleys are rotationally fixed in the pulley yokes, rotating shafts are connected with output shafts of the separation motors, the filter cloth is located in the separation kettle and is in a pocket shape, the bottom ends of the multiple drawing ropes are evenly bound to the outer edge of the filter cloth, the other ends of the drawing ropes stretch out of the separation kettle and are bound to the fixed pulleys, and the gravel separation effect is good.

Description

【Technical field】 [0001] The invention relates to the technical field of sediment separation, in particular to the technical field of a recoil type sediment separation device. 【Background technique】 [0002] With the rapid development of society, commercial concrete as a construction of social infrastructure is also developing rapidly. In order to protect the environment, on-site mixing is usually not allowed on urban construction sites. Therefore, PC mixing plants dedicated to concrete mixing have emerged as the times require, and they are transported with torpedo tanks. In order to save energy, the remaining concrete in the mixing plant and torpedo tank must be washed and separated. However, after the existing sand and gravel separator is used for a period of time, the filter screen will be blocked by fine stones and other particles, resulting in incomplete separation of waste materials, and the concentration of mortar in the drum is increasing until the sand on the drum ...

AI Technical Summary

Problems solved by technology

However, after the existing sand and gravel separator is used for a period of time, the filter screen will be blocked by fine stones and other particles, resulting in incomplete separation of waste materials, and the concentration of mortar in the drum is increasing until the sand on the drum All filters are blocked

In addition, in the process of separating the sand and stone from the flushing wastewater by the existing sand separator, usually only stones are separated, and the discharged wastewater still contains sand, which is easy to cause environmental pollution
