[0024] Please refer to Figures 1-3As shown in the figure, a cutting fluid filtering and impurity removing device includes a fixed bottom plate 1; a storage barrel 3 is hermetically and fixedly connected to the fixed bottom plate 1; a first spacer barrel 4 is slidably sleeved on the storage barrel 3; a plurality of fine filtering holes 5 are formed at the lower end of the first spacer barrel 4; a second spacer barrel 6 is slidably sleeved on the first spacer barrel 4; a plurality of side filtering holes 8 are formed on the inner wall of the second spacer barrel 6, and a plurality of bottom filtering holes 9 are formed on the bottom surface; an elastic member 7 is sleeved on the first spacer barrel 4 corresponding to the second spacer barrel 6; during operation, by placing the device at the lower end of the cutting fluid collecting pipe of the machining center, the used cutting fluid drops and converges in the second spacer barrel 6, and then is filtered through the side filtering holes 8 and the bottom filtering holes 9. Then, the preliminarily filtered cutting fluid enters the first spacer barrel 4 and is filtered again through the fine filtering holes 5. Then, the filtered cutting fluid accumulates in the storage barrel 3 and can be exported for recycling. It realizes a small volume, simple structure and large use volume, can be used in combination with the machining center, and solves the problem that the existing cutting fluid filtering device has a large volume, complex structure and cannot be used in combination with the machining center.

[0025] An inclined plane ring 10 is detachably and fixedly connected to the first spacer barrel 4 corresponding to the side filtering holes 8; a fastener 16 is threadedly inserted into the second spacer barrel 6 corresponding to the opening of the first spacer barrel 4; during operation, the cutting fluid filtered out from the upper side filtering holes 8 can be guided into the lower side filtering holes 8 through the inclined plane ring 10, and then filtered through the bottom filtering holes 9, so that the cutting fluid will not remain and accumulate, and thus can be recycled; the fastener 16 can limit the second spacer barrel 6 from detaching from the first spacer barrel 4, making it safer during use and solving the problem of waste caused by a large amount of residue in the existing filtering device.

[0026] A plurality of second air exchange holes 15 are formed on the side surface of the first spacer barrel 4; a plurality of first air exchange holes 11 are formed at the upper end of the second spacer barrel 6; during operation, through the first air exchange holes 11 and the second air exchange holes 15, the up and down movement of the second spacer barrel 6 and the first spacer barrel 4 is not affected by air pressure, and can be directly affected by gravity and the elastic force of the elastic member 7, so as to directly observe the weight of the filtered chips. Thus, after too much chips are accumulated, it can be judged in time and quickly transferred, so that the filtering effect of the side filtering holes 8 and the bottom filtering holes 9 is always maintained at the highest level, solving the problem that the existing filtering device has a complex structure and is prone to damage after long-term use of electrical equipment.

[0027] A discharge pipe 13 is fixedly connected to the side of the storage barrel 3 through an opening; an upper inlet groove 14 is formed on the upper surface of the discharge pipe 13; during operation, by externally connecting a suction pump to the discharge pipe 13, the cutting fluid after filtration and impurity removal can be transferred to the machining center for reuse; through the upper inlet groove 14, the cutting fluid at the bottom of the storage barrel 3 is not directly sucked, realizing further filtration and solving the problem of low filtration efficiency caused by low filtration layers in the existing filtration device.

Then the preliminarily filtered cutting fluid enters the first partition barrel 4 and is filtered again through the fine filtration holes 5. Then the filtered cutting fluid accumulates in the storage barrel 3 and can be exported for recycling use. It realizes a small volume, simple structure and large usable volume, can be used in combination with the machining center, and solves the problem that the existing cutting fluid filtration device has a large volume and complex structure and cannot be used in combination with the machining center; through the inclined surface ring 10, the cutting fluid filtered out from the upper side filtration holes 8 can be guided into the lower side filtration holes 8 and then filtered through the bottom filtration holes 9, so that the cutting fluid will not remain and accumulate, and thus the recycling use can be completed; through the fastener 16, the second partition barrel 6 can be restricted from detaching from the first partition barrel 4, making it safer to use during operation and solving the problem of waste caused by a large amount of residue in the existing filtration device.
