the lower end of the filter cloth 12 is connected to the bottom of the box body 13 through a rope 11; the upper end of the filter cloth 12 passes through the interval between the support body 10 and the top plate 5 and is connected with a tension spring 24, and the lower end of the tension spring 24 is fixed on the bottom plate 6 at the outer side of the support body 10.
To facilitate the return flow, the outlet pipe 3 is connected to a pump 15.
In order to realize the automatic box 13 upward movement that promotes, the bottom of shell 1 be fixed with about two electric telescopic handle 16, the bottom of box 13 is fixed with annular track 17, the upper end of two electric telescopic handle 16 all is equipped with the buckle 18 of card on the arc track.
In order to realize that motor 4 drives roof 5 and rotates, water inlet 9 in install a plurality of strengthening ribs 22, the middle part of a plurality of strengthening ribs 22 is fixed with the back shaft 23 that runs through the shell 1 top, motor 4 drives back shaft 23 and rotates after slowing down and the switching-over.
In order to avoid liquid accumulation inside the box body 13, the bottom of the box body 13 is in a filter screen shape.
In order to prevent the box body 13 and the bottom plate 6 from being separated, after the electric telescopic rod 16 is contracted, the upper end surface of the second baffle plate 14 is flush with the upper end surface of the bottom plate 6.
When the cutting fluid cutting machine is used, firstly, the motor 4 is started, and the control valve of the water inlet pipe 2 is opened, so that the used cutting fluid enters a position between the bottom plate 6 and the top plate 5 through the water inlet 9.
Along with the rotation of the motor 4, the filter body is also driven to rotate together, namely the bottom plate 6, the top plate 5 and the filter body at the upper part; and the lower housing 13 are driven to rotate together.
Since the box body 13 is not lifted up by the electric telescopic rod 16 in the initial state, that is, referring to fig. 2, the second baffle 14 is in the non-lifted state, that is, the upper end surface of the second baffle 14 is flush with the upper end surface of the bottom plate 6, and the first baffle 7 and the second baffle 14 do not form a barreled structure.
