The utilization ratio of high accuracy equipment has been improved greatly, and only second filter equipment and third filter equipment produce the consumptive material, have reduced equipment use cost, have improved machining efficiency, and the mill's income also can show the promotion thereupon.

As a preferred embodiment of the present invention, a side wall of the main water tank 2 is communicated with a side wall of the primary water tank 11 through a side channel, the primary screen 3 is installed in the side channel, and the primary screen 3 is an 80-mesh filter screen. I.e. the filtration accuracy of the primary screen 3 is 187.5 um.

Preferably, the combination of paper bag and fretwork bucket is all adopted to paper bag filter vat and paper bag net bucket, and the paper bag is convenient for change and dismantles, and the fretwork bucket is convenient for fix and fix a position, and when filter equipment's filter fineness descends, only need to change the filtration paper bag that corresponds, can guarantee that the filtration process continues to go on, has avoided the maintenance, has improved filtration efficiency.

(1) Lubricating fluid, solution to be filtered or cutting fluid after cleaning the abrasive cutting tools enters the main water tank 2 under the action of a pump or gravity. Under the action of water pressure, the solution or cutting fluid to be filtered passes through the primary screen 3 and enters the primary water tank 11, particles larger than 187.5um are blocked in the main water tank 2, and particles smaller than or equal to 187.5um enter the primary water tank 11;

(2) pumping the primary filtering cutting fluid in the primary water tank 11 into the secondary water tank 12 by a first filtering lifting pump, retaining particles larger than 20um in the primary water tank by the filtering action of the first filtering lifting pump 4, and pumping particles smaller than or equal to 20um into the secondary water tank 12;

(3) after being filtered by the second filtering device 5 (paper bag filtering barrel), the particles larger than 10um are left in the second filtering device 5 or the secondary water tank 12, and the particles smaller than 10um enter the tertiary water tank 13 through the second filtering lift pump 6;

(4) through the filtration of third filter equipment 7 (container bag net bucket), the granule that is greater than 1um is stayed in third filter equipment 7 or tertiary water tank 13, and the cutting fluid mixture that is less than 1um passes through the abrasive cutting department of lathe pump 8 transport lathe, and the cutting fluid of 1um and virus after the filtration sprays on the grinding cutting sword, washs the piece on it, still cools off the tool bit, because the cutting fluid granule is less than 1um, therefore the grinding cutting precision is high, and the pottery that processes is of high quality.

The device also comprises a plurality of detection alarm devices 9 which are respectively arranged inside the first-stage water tank 11, the second-stage water tank 12 and the third-stage water tank 13 and are used for detecting filtering residues in the water tanks at all stages. The detection alarm device 9 detects the liquid level of the water tank and the pressure of accumulated dregs in the filtering and pricking device, and when the detected liquid level or pressure is greater than the preset liquid level or pressure value, an alarm is given out to remind a worker to check the water tank or replace the filtering device in time so as to ensure the precision of subsequent filtering.

Specifically, the overall filtering process of the present invention is as follows:

as shown in FIGS. 1 and 4, as a preferred embodiment of the present invention, the detection alarm device 9 includes

The three liquid level alarm devices 91 are respectively arranged at the middle upper parts of the inner walls of the first-stage water tank 11, the second-stage water tank 12 and the third-stage water tank 13 and alarm when the liquid level in the water tanks exceeds a liquid level threshold value;

a pressure alarm device 92, which is arranged at the bottom end of the interior of the third filtering device 7 and alarms when the detected pressure is greater than the pressure threshold value;

the single chip microcomputer 93 is connected with the three liquid level alarm devices 91 and the two pressure alarm devices 92;

a pump controller 94 for controlling the start and stop of the first filtration lift pump 4, the second filtration lift pump 6 and the machine tool pump 8. The single chip microcomputer 93 and the pump controller 94 can be both arranged on the inner wall of the box body 1.

It is added that the liquid inlet speed and the liquid outlet speed in each water tank are kept consistent under the condition that the filtering progress is normal. The liquid level is lower than the liquid level threshold of the liquid level alarm device 91. When filter equipment damages, generally can block up the filter mesh, consequently can make out liquid speed and be less than the inlet liquid speed, the liquid level can slowly rise this moment, when liquid level alarm device 91 detects the liquid level and reaches the liquid level threshold value, reports to the police.

When the solid particles accumulated in the filtering device (the particles larger than the inner diameter of the filter mesh of the current filtering device) are too much, the pressure sensor can detect large pressure, the filtering efficiency can be influenced when the residues are too much, therefore, the filtering residues need to be cleaned in time, an alarm is given when the pressure value detected by the pressure sensor is larger than a preset pressure threshold value, and a worker is reminded to clean the filtering residues in time or replace a filter paper bag so as to ensure the filtering precision and the filtering efficiency.

As a preferred embodiment of the present invention, when any one of the liquid level alarm device 91 or the pressure alarm device 92 gives an alarm, the single chip microcomputer 93 receives the alarm signal, the single chip microcomputer 93 sends a control signal to the pump controller 94, and the pump controller 94 controls the first filtration lift pump, the second filtration lift pump 6 and the machine tool pump 8 to stop operating, so as to avoid continuous filtration under the condition of abnormal filtration or damage of the filtration device, directly interrupt filtration and transportation of the cutting fluid, thereby interrupting the filtration process, and re-performing filtration after maintenance or replacement of a new filtration paper bag, thereby ensuring the filtration precision and quality.

Preferably, the fault position of the filtering device can be effectively monitored by the arranged detection alarm device, so that the filtering core can be replaced in time to ensure the filtering precision, the problem of trouble in fault maintenance and maintenance of the water tank is solved, and the maintenance efficiency of the water tank is improved.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
