split flow filter

Abstract

The split-flow filter device of the present invention basically includes: a set of return water pipelines, a pressurized pump, a pre-filter module, a set of flow pipelines, at least one water quality adjustment module, and a water quality detection module , and a control circuit; under normal conditions, the water in the washing tank can be formed by a pressurized pump, at least circulating between the pre-filter module and the washing tank, and the impurities in the water can be filtered out in real time; and, when the water quality is detected When the measurement module detects that the water quality condition flowing through the pre-filter module exceeds the preset standard value, it will open the second valve part and close the first valve part at the same time under the control of the control circuit to forcibly guide the water flowing through the pre-filter module. The water of the filter module passes through the water quality adjustment module located in the diversion pipeline, and under the action of the reaction material of the water quality adjustment module, it has a predetermined reaction with the passing water, and controls the flow of the washing tank in a relatively more active and reliable way. Water cleanliness.

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
