Combined pretreatment device

Abstract

The invention discloses a combined pretreatment device which comprises a pipe main body, wherein the pipe main body comprises a main pipe and two branch pipes; the two branch pipes are a first branch pipe and a second branch pipe separately; the main pipe comprises a plurality of connection pipes, and tee joints A, B and C, wherein the tee joints A, B and C are arranged from bottom to top and are communicated through a connection pipe separately; the first branch pipe is connected with the tee joint A; the second branch is connected with the tee joint C; a floater is arranged in a manner of penetrating through the inside of the tee joints B and C; the floater can float in the tee joint B up and down and is supported on the connection pipe at the upper part of the tee joint C through a plug cap and a blind nut; and a sampling opening and a black washing opening are formed in the tee joint B. The combined pretreatment device is simple and clear in structure, convenient to maintain and not easy to block; and the floater is arranged in a pretreatment pipe, so that monitoring whether the pretreatment device is running or not by maintenance personnel is facilitated.

Description

Technical field [0001] The invention relates to a combined pretreatment device and belongs to the technical field of water quality detection. Background technique [0002] Generally, in the field of sewage pretreatment, the pretreatment pipeline used is more complicated, which will cause blockage in the short-term accumulation process, and personnel cannot well check whether the equipment is operating normally; it is not easy to maintain and repair in the complex pretreatment management. Cost and construction cost are relatively high; construction conditions also have limitations. Summary of the invention [0003] The purpose of the present invention is to provide a combined pretreatment device, which has simple pipelines, is not easy to be blocked, has monitorable operation, and is convenient for maintenance. [0004] In order to achieve the above objective, the technical solution adopted by the present invention is a combined pretreatment device including a pipeline main body; th...
