Waste water detector convenient to clean and having good collection effect

Abstract

The invention relates to a sewage detector which is convenient to clean and has a good collection effect, comprising a water sample detector, the inner chamber of the water sample detector is fixedly connected with one end of a water inlet pipe, and one end of the water inlet pipe is threadedly connected with a water pump, and the inside of the water pipe is A push-pull rod is plugged in, the top of the push-pull rod is fixedly connected with a handle, and the bottom end of the push-pull rod is fixedly connected with a piston. The piston is located inside the pumping cylinder, and the surface of the piston overlaps the inner wall of the pumping cylinder. A threaded pipe is connected, the bottom end of the threaded pipe is threadedly connected with a threaded sleeve, the bottom end of the threaded sleeve is fixedly connected with a water inlet, the surface of the water inlet head is provided with a water inlet, and the inner cavity of the water inlet head is fixedly connected with a first unit A directional valve, a second one-way valve is provided at the joint between the surface of the water pumping tube and the water inlet pipe, a fixed ring is sleeved on the surface of the water pumping tube, and an extension rod is fixedly connected to the surface of the fixed ring. The invention has the advantages of easy cleaning and good collection effect.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sewage detector which is convenient for cleaning and has good collection effect. Background technique [0002] With the rapid development of my country's economy, many chemical companies have started construction in cities, and the industrial sewage discharged by many enterprises has not passed strict testing. The pollution of resources has become a serious environmental protection problem. In order to effectively control the sewage discharge, it is necessary to test the sewage before the sewage is discharged. Due to the different components in the sewage, the components of the sewage at different levels are different. [0003] At present, the sewage detectors on the market often extract and detect the sewage below the liquid level when collecting sewage, which causes the problem of inaccurate sewage collection, and the detector needs to be cleaned after each de...
