Flow dividing type filter device

Abstract

The invention provides a flow dividing type filter device. The flow dividing type filter device basically comprises a set of water return pipelines, a booster pump, a front filter module, a set of flow dividing pipelines, at least one water quality adjusting module, a water quality detection module and a control circuit. In an ordinary state, water can be pumped to a washing tank through the booster pump and circulate at least between the front filter module and the washing tank, and impurities in water are filtered out in real time. When the water quality detection module detects that the water quality condition of water flowing through the front filter module exceeds a preset standard value, under the control of the control circuit, a second valve is opened, a first valve is closed at the same time, the water flowing through the front filter module is forcibly guided to flow through the water quality adjusting module located on the flow dividing pipelines, a preset reaction is conducted between the water flowing through the water quality adjusting module and reaction materials of the water quality adjusting module, and therefore water cleanliness of the washing tank is controlled through a relatively positive and reliable measure.

Description

technical field [0001] The invention relates to a filtering device, in particular to a split-flow filtering device that can effectively control the water cleanliness of a washing tank. Background technique [0002] Press, printed circuit board (printed circuit board, pcb) is mainly based on the circuit design, draws the wiring pattern of the electrical wiring connecting the circuit parts, and then uses mechanical and chemical processing, surface treatment, etc. to reproduce the electrical conductor on the insulator. formed circuit board. In other words, the printed circuit board is the substrate before matching the electronic parts. Its function is mainly to use the electronic circuit formed by the electronic parts and the circuit board to play the functions of the electronic components to achieve the purpose of signal processing. [0003] In the production process of general printed circuit boards, it is usually necessary to perform processing operations on the substrate, ...

AI Technical Summary

Problems solved by technology

[0006] However, in actual operation similar to the existing washing tank 12, clean water must be continuously injected into the second tank body 122 to maintain the water quality cleanliness of the second tank body 122, which not only consumes more water resources , and it is impossible to control the water cleanliness of the second tank body 122; moreover, all the wastewater discharged from the first tank body 121 by all the washing tanks 12 is concentrated in a wastewater treatment equipment for purification treatment, which not only consumes more wastewater treatment costs , and relatively increase the burden on wastewater treatment equipment
