Embodiment

Below in conjunction with specific embodiment, the invention will be further described.

This inherent filtration row cuts pump, the base of motor 1 and the housing of supply pump 3 are fixed together, the output shaft of motor 1 is connected with the pump main shaft 9 of supply pump 3 by coupling 2, the liquid entering hole of supply pump 3 is fixed with adpting flange 4, supply pump 3 has liquid outlet 17 and spill pipe 13, spill pipe 13 is provided with relief valve 18, adpting flange 4 is fixed with filter housing 6, on filter housing 6, mouth 16 is cut by the row of being provided with, stator blade 7 is fixed with at the inwall of filter housing 6, filter housing lower cover 15 is fixed with in the underpart of filter housing 6, feed liquor filter screen 14 is fixed with in the underpart of filter housing lower cover 15, the adpting flange 4 of described filter housing 6 inside is fixed with filter screen skeleton 5, filter screen skeleton 5 is fixed with fluid filter screen 19, described pump main shaft 9 is positioned at filter screen skeleton 5, the pump main shaft 9 of corresponding filter screen skeleton 5 inside is fixed with recoil impeller 8, impeller 12 is fixed with in the underpart of pump main shaft 9, pump main shaft 9 above impeller 12 is fixed with by mounting cover 11 and rotates circle 10, rotate circle 10 between filter housing 6 and fluid filter screen 19.

Described supply pump 3 is Gerotor pump or plunger pump.

Described row cuts the position, upper end portion that mouth 16 is positioned at filter housing 6.

In the present invention, motor 1 is connected with supply pump 3, drives pump main shaft 9 to rotate by motor 1 by coupling 2; Recoil impeller 8 is arranged on pump main shaft 9; Frame of filter element 5 is arranged on adpting flange 4; Adpting flange 4 is connected with supply pump 3; Impeller 12, mounting cover 11 and rotation circle 10 are arranged on pump main shaft 9; Filter housing 6 is fixed on filter housing lower cover 15 middle with adpting flange 4; Finally feed liquor filter screen 14 is arranged on filter housing lower cover 15.

Working principle of the present invention is as follows:

Cooling liquid flows into from feed liquor filter screen 14, is rotated by impeller 12, cooling liquid is delivered in filter housing 6, after the filtration of fluid filter screen 19, is supplied to pump 3 and sucks, enter the cooling system of match equipment finally by liquid outlet 17; Cooling liquid after coolant pump inherent filtration, cut mouth 16 by row to discharge, the filtration of the cutting particles installed on tank for coolant and powder recovery case, cutting particles and powder are stayed in cutting particles and powder recovery case, clean cooling liquid is got back in cooler bin; When the pressure in supply pump 3 exceedes its rated pressure, cooling liquid, through relief valve 18, is back in cooling liquid casing from spill pipe 13; Relief valve 18 can carry out pressure adjustment to the cutting fluid of liquid outlet 17.

Note: cooling-liquid level is not less than impeller 14 the highest 20mm users and installs cutting particles and powder recovery case on tank for coolant, convenient collection cutting particles and powder.

It is as follows that inherent filtration of the present invention cuts principle from row:

Motor 1 drives supply pump 3 to work, and drives pump main shaft 9 to rotate, and pump main shaft 9 drives recoil impeller 8 to rotate, and produces recoil force, take away cutting particles and the powder at fluid filter screen 19 outer surface feed liquor place in fluid filter screen 19 to fluid filter screen 19;

Pump main shaft 9 driven rotary circle 10 rotates, and forms vacuum, siphon away cutting particles and the powder at fluid filter screen 19 outer surface feed liquor place between rotation circle 10 and fluid filter screen 19;

Rotated and stator blade 7 acting in conjunction on filter housing 6 by the rotation blade rotated on circle 10, the cutting fluid in the outer surface of fluid filter screen 19 and filter housing 6 is made to produce turbulent flow, under taking away backwash and vacuum action, the cutting particles separated and powder, cut mouth 16 by row and discharge;

By above-mentioned filter type, make the supply of cutting fluid, filter and complete together in the filter housing of pump, ensure the turbidity test of liquid outlet cutting fluid, and filter core is cleaned simultaneously, guarantee filter core is clean, prolonging service life of filter elements, the row of eventually passing cuts mouth and will filter and isolated cutting particles and powder discharge, ensure that the cleaning of cutting fluid case simultaneously.
