Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the sewage after laser wet cutting contains a large amount of debris, which is very harmful to the environment. A water circulation system used in the laser wet cutting system is provided, which can recycle and filter the sewage. Water can be recycled, saving energy and reducing emissions, reducing water consumption

Embodiment Construction

[0020] according to figure 1 In the water circulation process of the water circulation system shown, the sewage generated during the laser wet cutting process mainly comes from: the cooling water of the dust collection device, the recovery water of the main recovery pipe, and the recovery water collected by the leakage channel of the workbench; the above sewage all enters the main water inlet pipe Then it reaches the cotton filter cup for primary filtration, and the filtered low-pressure water enters the water tank and water pump in turn; then reaches the filter cup for secondary filtration, and the filtered high-pressure water is stored in the water storage tank. The first solenoid valve controls the stop and action of the motor by comparing the water flow with the upper and lower limits; when the flow is higher than the upper limit, the motor is controlled to stop moving; when the flow is lower than the lower limit, the motor is controlled to act; the second solenoid valve I...

Abstract

The invention relates to a filter core-type water circulation system for a laser wet-cutting system and a water circulation method therefor. The filter core-type water circulation system comprises a sewage recovery system, a filter core filtration device and a water storage tank. The filter core filtration device comprises two cotton filter core cups. Sewage orderly passes through the two cotton filter core cups and is subjected to two filtration processes. The filter core-type water circulation system has the advantages that through the two filtration processes, filtration effects are good; the whole system has fewer parts and a simple structure; and the sewage produced by laser wet-cutting can be recycled so that energy saving and emission reduction are realized and water consumption is reduced.

Description

technical field [0001] The invention relates to a filter element type water circulation system for laser wet cutting during laser micromachining of thin-walled pipes, and belongs to the technical field of laser micromachining. Background technique [0002] Generally, there are two types of laser micromachining processes: dry cutting and wet cutting. Since wet cutting plays an important role in keeping the temperature of the heat-affected zone at a minimum, and at the same time, molten metal and metal vapor will be deposited on the surface of the workpiece in large quantities during laser cutting, the cooling water introduced by wet cutting will produce a thin layer of water on the surface of the workpiece The particles falling on the film cool quickly and cannot be bonded to the surface of the workpiece, so it is very necessary to introduce water flow during laser micromachining. [0003] The processed sewage contains a lot of debris. If non-metallic materials are cut, the ...
