Description

Technical Field

[0001] The utility model relates to the technical field of coolant filtration, in particular to an impurity filtering device for coolant. Background Art

[0002] Turning coolant, also known as cutting fluid or cutting coolant, is a liquid used in the turning process to improve the cutting effect. It is mainly composed of a mixture of water, oil and additives, and has multiple functions such as cooling, lubrication and flushing.

[0003] The existing technology does not have a structure for quickly cleaning the coolant filter during use, so that the internal filter element of the existing coolant filter is mostly directly scrapped and replaced after reaching the end of its service life. However, since the coolant contains a lot of impurities, the filter element needs to be replaced many times in a short period of time, which is wasteful and cumbersome. Based on the shortcomings of the existing technology, the utility model designs an impurity filtering device for coolant. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an impurity filtering device for coolant, which has the advantage of rapid cleaning of the coolant filter.

[0005] The utility model provides the following technical solution: a coolant impurity filter device, comprising a filter cartridge body, a separator ring fixedly connected to the interior of the filter cartridge body, and a cleaning mechanism provided at the bottom of the inner cavity of the filter cartridge body for facilitating cleaning and draining of the filter device;

[0006] The cleaning mechanism includes a base plate, a reducer, a motor, a transmission shaft, a connecting arm and a scraper. The base plate is fixedly connected to the inner side of the bottom end of the filter cartridge body, the reducer is fixedly connected to the bottom of the base plate, the motor is fixedly connected to one side of the reducer, the transmission shaft passes through the base plate and is rotatably connected to the output end of the reducer, the connecting arm is fixedly connected to the top side wall of the transmission shaft, and the scraper is fixedly connected to the outer end of the connecting arm.

[0007] As an optimal technical solution of the present invention, the cleaning mechanism also includes a fine-porous filter element, a drain pipe and a sealing ring. The fine-porous filter element is fixedly connected to the lower surface of the separating ring, the drain pipe is fixedly connected to the bottom of the fine-porous filter element, and the sealing ring is fixedly connected to the bottom of the fine-porous filter element.

[0008] As a preferred technical solution of the present invention, the outer surface of the filter cartridge body is fixedly connected to a liquid inlet pipe, the outer surface of the filter cartridge body is fixedly connected to a liquid discharge pipe, and the outer surface of the filter cartridge body is fixedly connected to a support leg.

[0009] As a preferred technical solution of the present invention, a coarse-pore filter element is fixedly connected to the upper surface of the separation ring, and a top cover is provided on the upper surface of the coarse-pore filter element.

[0010] As a preferred technical solution of the present invention, the inner end of the liquid inlet pipe is arranged above the separation ring, and the inner end of the liquid discharge pipe is arranged below the separation ring.

[0011] As a preferred technical solution of the present invention, the top cover is fixedly connected to the top end of the filter cartridge body.

[0012] As a preferred technical solution of the present invention, the scraper is rotatably connected to the interior of the fine-porous filter element, and the outer side of the scraper is in contact with the inner wall of the fine-porous filter element.

[0013] As a preferred technical solution of the present invention, the output end of the motor is connected to the reducer, the outer end of the sewage pipe extends outward through the bottom plate, and the transmission shaft is rotatably connected to the inside of the sealing ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This impurity filtering device for coolant stops delivering liquid into the filter cartridge body, then starts the motor to rotate the drive shaft through the reducer. The rotating drive shaft drives the scraper to rotate on the inner wall and the bottom of the inner cavity of the fine-porous filter element through the connecting arm, so that the scraper scrapes off the impurities and debris adhered to or accumulated on the inner wall and the bottom of the fine-porous filter element. During the scraping process, the impurities and debris slide from the inner wall and are transferred to the inside of the drain pipe. Finally, the drain pipe is opened to clean and remove the internal impurities. This device is convenient for cleaning the fine-porous filter element.

[0016] 2. This impurity filtering device for coolant injects coolant into the filter cartridge body through the liquid inlet pipe. The coolant entering the filter cartridge body will first enter the coarse-pore filter element from the inside of the filter cartridge body for preliminary filtration. The pre-filtered coolant entering the coarse-pore filter element flows downward from the inside of the coarse-pore filter element into the inside of the fine-pore filter element under the action of gravity. At this time, the coolant that has undergone secondary filtration is squeezed out of the fine-pore filter element under the action of continuous liquid inflow, completing three filtrations. Finally, the coolant that has completed three filtrations can be discharged and collected from the drain pipe. This device is convenient for multi-stage filtration of coolant.

[0026] A fine-porous filter element 304 is provided to facilitate the third filtration of the coolant. A scraper 309 is provided to scrape the inner wall and the bottom of the inner cavity of the fine-porous filter element 304, thereby cleaning the sludge, impurities and debris filtered out from the fine-porous filter element 304 and improving the service life of the fine-porous filter element 304. A drain pipe 305 is provided to facilitate the discharge of the scraped sludge, impurities and debris, thereby avoiding the situation where the sludge, impurities and debris cannot be discharged and affect subsequent filtering operations.

[0027] See also Figure 3-4 A coarse-pore filter element 201 is fixedly connected to the upper surface of the separation ring 2 , and a top cover 202 is provided on the upper surface of the coarse-pore filter element 201 . The top cover 202 is fixedly connected to the top inner part of the filter cartridge body 1 .

[0028] By providing the separation ring 2 , the inner cavity of the filter cartridge body 1 is conveniently divided into two upper and lower cavities, while effectively preventing the coolant from being directly discharged from the drain pipe 102 after being filtered by the coarse-pore filter element 201 and the fine-pore filter element 304 .

[0029] Working principle: when a coolant impurity filtering device is used, in the initial state, first, the separation ring 2 is set inside the filter cartridge body 1, and a coarse-pore filter element 201 and a fine-pore filter element 304 are respectively provided on the upper and lower sides of the separation ring 2, and a liquid inlet pipe 101 and a liquid discharge pipe 102 are provided on the outer surface of the filter cartridge body 1 to facilitate filtering impurities in the coolant.

[0031] When multi-stage filtration of the coolant is required, the coolant is first injected into the filter cartridge body 1 from the liquid inlet pipe 101. The coolant entering the filter cartridge body 1 will first enter the coarse-pore filter element 201 from the inside of the filter cartridge body 1 for preliminary filtration. The pre-filtered coolant entering the coarse-pore filter element 201 flows downward from the inside of the coarse-pore filter element 201 into the inside of the fine-pore filter element 304 under the action of gravity. At this time, the coolant that has undergone secondary filtration is squeezed out of the fine-pore filter element 304 under the action of continuous liquid inflow, completing three filtrations. Finally, the coolant that has completed three filtrations can be discharged and collected from the drain pipe 102. This device is convenient for multi-stage filtration of the coolant.
