Instrument for conveniently detecting heavy metals in wastewater for metal factory

Abstract

The invention relates to the technical field of industrial detection equipment, and discloses an instrument for conveniently detecting heavy metals in wastewater for a metal factory. A display screenis fixedly connected to the upper part of the surface of a machine body, a control panel is fixedly connected to the lower part of the surface of the machine body, a left mounting chamber is formed inthe machine body and on the left side of the display screen, an output shaft of a built-in power supply is fixedly connected with a connecting wire, and a through hole is formed in the upper surfaceof the left mounting chamber. The built-in power supply is electrically connected to an electromagnetic disc by virtue of the connecting wire, an electromagnet is attracted or pushed by virtue of theelectromagnetic attraction of the electromagnetic disc, and a pulse dust collector is driven to remove dust on the inner surface of the display screen by virtue of the displacement of a moving seat, so that the effect of cleaning water mist, dirt, rust and the like on the inner surface of the display screen by virtue of a vertical reciprocating displacement mode of the built-in pulse dust collector on the premise that the instrument is not disassembled is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial testing equipment, in particular to an instrument used in metal factories to detect heavy metals in waste water. Background technique [0002] Easy to detect heavy metals in wastewater The instrument is mainly used to detect metals. All metals, including iron and non-ferrous metals, have high detection sensitivity. Generally, non-ferromagnetic metals entering the detection area will produce eddy current effects, which will also change the magnetic field distribution in the detection area, so they are very commonly used in many working environments. [0003] Existing metal factories use instruments that are easy to detect heavy metals in wastewater. When in use, because they are often used to detect heavy metals in water, after long-term use, the interior of the instrument is prone to produce considerable water mist and dirt due to high humidity. Even rust, because the display screen is the mos...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an instrument for detecting heavy metals in waste water used in metal factories. It has the method of moving up and down through the built-in pulse dust collector without disassembling the instrument. The advantages of cleaning the water mist, dirt and even rust spots on the surface solve the problem that the existing metal factories use instruments that are easy to detect heavy metals in wastewater. Most of them cannot clean the water mist, dirt and even rust inside the instrument without disassembly The problem of dealing with the situation
