Upper discharge device of filtering tank

Abstract

The invention discloses an upper discharge device of a filtering tank, which comprises floating balls, a connection rack, a suction nozzle, a hose, a valve and a tank body, wherein the tank body is a closed container, the floating balls, the connection rack, the suction nozzle and the hose are arranged inside the tank body, at least three floating balls are fixed on the connection rack and float on the liquid surface, the suction nozzle is fixed on the connection rack, one end of the suction nozzle is inserted into the liquid surface, and the other end of the suction nozzle is communicated with a water discharge port on the upper part of the tank body through the hose. According to the filtering equipment and device applied to the fields of chemical industry and environment protection, after filtered liquid is settled, the clear liquid on the upper part is discharged by the upper discharge device, and residue and water separation is rapidly realized, so that the filtering efficiency is greatly improved.

Description

technical field [0001] The invention relates to the fields of chemical industry and environmental protection, in particular to an upper drainage device for a filter tank. Background technique [0002] In today's chemical and environmental protection fields, many sedimentation and filtration equipment and devices are used, especially when solid-liquid separation is required, and the solid matter has a low water content. The water content of the solid matter after precipitation treatment is still very high. High, further filtration or dehydration treatment is still required. Usually, the liquid to be filtered is filtered through the filter at the bottom and discharged, which makes the entire precipitation and filtration time-consuming and the efficiency of solid-liquid separation is greatly reduced. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention proposes a set of solutions for simultaneous sedimentation and filtration, ...
