Technical field
The present invention relates to the wet filer element type water circulation system of cutting of a kind of laser of thin-wall pipes in the Laser Micro-Machining process, belong to the laser micro-machining technology field.
Background technology
General Laser Micro-Machining technology has driedly cuts and wets and cut two kinds of technologies.Because wet cutting keeping having important function aspect the temperature minimum of heat affected area, motlten metal and metallic vapour can be deposited on surface of the work in a large number in laser cutting process simultaneously, the cooling water that wet incisal guide is gone into can produce the very thin moisture film of one deck at surface of the work, drop on the very fast cooling of particle on the film and can't be bonded in the surface of workpiece, it is very necessary therefore introducing current in the Laser Micro-Machining process.
Contain a large amount of chips in the sewage after the processing, if the cutting non-metal material, the flue dust and the air effect that produce in these nonmetallic materials laser processing procedures may generate noxious material, also can be taken out of by water under high pressure.The problem of environmental pollution of processing industry becomes increasingly conspicuous at present, becomes a problem demanding prompt solution.
Summary of the invention
The technical problem to be solved in the present invention is to contain a large amount of chips in the wet sewage of cutting after the processing of laser, and is very big to environmental hazard, and a kind of water circulation system that is used for the wet cutting system of laser is provided, can reclaim sewage and filter, water after the filtration can be recycling, and energy-saving and emission-reduction reduce water consumption.
In order to solve the problems of the technologies described above, the technical scheme that the present invention takes is as follows:
A kind of filer element type water circulation system that is used for the wet cutting system of laser is characterized in that described water circulation system comprises waste water recovery system, filter element filtering device and water tank.
Preferably, described waste water recovery system comprises that water inlet manifold and three outlets all connect the recovery tube of water inlet manifold, first recovery tube is used to reclaim the water that stays after the dust exhaust apparatus cooling, second recovery tube is used to reclaim pulp-collecting box and is dropped in water on the workbench, and the 3rd recovery tube is used for reclaiming the water of main recovery tube.
Preferably, described filter element filtering device comprises two cotton filter element cups, in each cotton filter element cup the filter core cotton is housed all, and two filter element cups carry out sewage water filtration successively, and the water after will filtering remains in the water tank.
Preferably, the sheathing material of cotton filter element cup adopts transparent material to make, to observe the situation of sewage water filtration at any time.
Preferably, two magnetic valves are installed on the water tank, wherein, first magnetic valve is that the numeral that is provided with upper and lower bound shows flow solenoid valve, be used to control stopping and moving of motor, when flow is higher than the upper limit, the stop motion of control motor, when flow is lower than lower limit, the control motor action; Second magnetic valve is arranged on the water side of water tank, is used to control the break-make of storage tank, to control water outlet and to cut off the water supply.
A kind of water round-robin method that is used for the wet cutting system of laser is characterized in that, sewage enters into first cotton filter element cup from water inlet manifold and carries out the filtration first time; Water after the filtration is pooled to water tank, carries out the second time by pump handle water from water tank pump to the second a cotton filter element cup again and filters; Water behind the secondary filter remains in the water tank.
Preferably, under being lower than, the flow of water prescribes a time limit, the first solenoid control motor action, and water pump is started working, and water is pumped into second cotton filter element cup from water tank filter, and the water after the filtration enters water tank; When the flow of water is higher than in limited time the first solenoid control motor stop motion.
Laser cutting is to be moved at metal tube upper edge line of cut by overlapped laser pulse point, imports the auxiliary fusing cutting of hyperbaric oxygen simultaneously.Laser focal spot material fusion and gasification, slag is blown out by the high pressure assist gas, forms cutting track on metal pipe-wall.The present invention utilizes flue dust, sewage and the metallic vapour in the dust exhaust apparatus absorption process.Through the cooled solid particle of cleaning dust exhaust apparatus, current are pooled to water inlet manifold; Cut in the process in that laser is wet, the pull pulp-collecting box has the part water droplet and drops on the workbench when getting material, has on workbench and leaks, and leaking links to each other with water inlet manifold.
After sewage entered cotton filter element cup, hydrone was up supplied water by the tiny space of cotton core braid, and oarse-grained impurity can not see through, thereby played the effect of filtered water.
Water circulation system provided by the invention is through twice filter element filtering, good filtration effect; And the part number of whole system is few, simple in structure; Can carry out recyclingly to the wet sewage of cutting after the processing of laser, energy-saving and emission-reduction reduce water consumption.
