Description

Technical Field

[0001] The utility model relates to the technical field of cooling liquid filtering devices. Background Art

[0002] In order to save production costs, companies usually recycle coolants. However, during the cutting process, some scrap metal from the workpieces will mix into the coolant. The recycling of unfiltered coolant will affect the production quality of the next cycle of workpieces. In order to improve production quality, companies usually set up filtering devices and cooling devices in sequence to filter and cool the coolant to facilitate the recycling of the coolant.

[0003] As for filtering the waste chips of the workpiece contained in the coolant, a filter is generally used for filtering. However, the particles of some waste chips are smaller than the filter holes, causing some waste chips to pass through the filter holes. The solution at this time is to install a magnet behind the filter to attract, aggregate and fix the waste chips of the workpiece, so that the filtered coolant does not contain waste chips of the workpiece. However, this method is only applicable to workpieces whose raw materials are magnetic metals. Non-magnetic metals cannot be attracted by magnets. Therefore, it cannot meet the filtering needs of non-magnetic metal workpieces. Utility Model Content

[0012] Preferably, the sweeping rod is made of rubber, and the pressing plate completely covers the inner cavity of the filter box on the side of the filter screen close to the heat dissipation pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1) The waste liquid of the coolant flows into the filter box through the liquid inlet pipe, and then is filtered through the filter screen. Then, the reciprocating push rod motor is started, and the reciprocating push rod motor drives the processing mechanism to run through the connecting plate.

The shaft then drives the drum to rotate through the connecting rod, and the drum drives the sweeping rod to rotate through the bottom rod to push away the waste chips at the bottom of the drum. At the same time, the diameter of the pores is smaller than the diameter of the filter holes to further prevent waste chips from entering the drum and then entering the top of the pressure plate, thereby achieving the effect of filtering the coolant again and achieving the filtering effect of non-magnetic metal waste chips.

[0026] The waste liquid of the coolant flows into the filter box 5 through the liquid inlet pipe 6, and then is filtered through the filter screen 11. Then, the reciprocating push rod motor 8 is started, and the reciprocating push rod motor 8 drives the processing mechanism to operate through the connecting plate 9. After being processed by the processing mechanism, the waste chips in the coolant are filtered out, and then the heat is dissipated through the heat dissipation pipe 2, and finally it is sucked into the water pump 1 and discharged back to the coolant storage tank for reuse, thereby achieving the effect of filtering the coolant.

The bottom end of the connecting plate 9 is connected to the first baffle 10, and the bottom end of the first baffle 10 is connected to the pressure plate 12. The pressure plate 12 is located on the side of the filter screen 11 close to the heat dissipation pipe 2. The bottom end of the outer wall of the pressure plate 12 is connected to the second baffle 13. The first baffle 10 and the second baffle 13 are staggered up and down. The contact between the first baffle 10 and the second baffle 13 and the filter box 5 is provided with a sealing strip. The outer wall of the first baffle 10 passes through the top of the filter box 5. The second baffle 13 is connected to the bottom end of the outer wall of the pressure plate 12.
