Sediment filtering device for water conservancy facilities and working method thereof

Abstract

The invention discloses a sediment filtering device for water conservancy facilities, belonging to the technical field of sediment filtering of water conservancy facilities. The sediment filtering device comprises: a supporting assembly, which comprises a shell; a sealing assembly, which comprises a sealing cover that is detachably inserted into the bottom of the shell; a filtering assembly, which comprises two sets of frame bodies, wherein the tops of the two sets of frame bodies are fixed to the inner walls of the left side and the right side of the top of the shell correspondingly, and flexible filter screens are movably arranged in the two sets of frame bodies; and a filter screen treatment assembly, which comprises a mounting shell fixed at the top of the shell. According to the invention, a servo motor is driven to drive a driving shaft to rotate so as to enable a power roller to wind the flexible filter screens, a blocked part in the flexible filter screen enters a mounting shell; and meanwhile, during winding, a movable rod moves up and down to drive a connecting block through a movable column so as to enable a rocker arm to swing in a reciprocating manner, so a knocking block knocks blocked parts in the flexible filter screens in a reciprocating manner, and silt blocking meshes in the flexible filter screens downwardly enters a collecting box; and thus, cleaning efficiency is high, and cleaning quality is good.

Description

technical field [0001] The invention relates to the technical field of sediment filtering for water conservancy facilities, in particular to a sediment filtering device and working method for water conservancy facilities. Background technique [0002] With the development of social productivity, water conservancy has been developing continuously and has become an important pillar of human social civilization and economic development. Water conservancy facilities involve many fields such as flood control, drainage, irrigation, shipping and urban water supply and power generation. play a vital role. [0003] Water conservancy facilities also face many difficulties in the process of use. Among them, the sediment in the sewage is one of the important factors leading to the water conservancy facilities.

Problems solved by technology

[0003] Water conservancy facilities also face many difficulties in the process of use. Among them, the sediment in the sewage is one of the important factors leading to the water conservancy facilities. If the sediment in the sewage is not filtered out by the filter device, it will cause serious environmental pollution. Most of the existing filtering devices use filter nets or filter plates for filtering. Although they can filter the sediment well, the sediment is easy to accumulate on the filter nets or filter plates, resulting in a decrease in the filtering effect or occurrence of For the situation that cannot be filtered out, most of the existing methods use manual cleaning after the work is over or install a cleaning mechanism inside. The former is time-consuming and laborious, and it needs to be shut down every time it is cleaned, which is troublesome and affects work efficiency. The cleaning effect is poor, and often only the sediment on the surface of the filter screen or filter plate can be removed, but the sediment in the filter holes or meshes in the filter screen or filter plate cannot be removed. For this reason, we propose a water conservancy Sediment filtering device and working method of the facility
