[0024] Example: Figures 1-4 As shown, a grinding fluid filtration device includes a housing 100, a water inlet assembly 200, a first water outlet control assembly 300, a second water outlet control assembly 400, and a circulation pump 500. The housing 100 is divided into a filtration chamber 110, a water storage chamber 120, a circulation chamber 130, and a storage chamber 140 from top to bottom. The water inlet assembly 200 is installed in the filtration chamber 110. The first water outlet control assembly 300 includes a first water outlet valve 320 and a water outlet pipe 330. When the first water outlet valve 320 is closed, the grinding fluid delivered by the water inlet assembly 200 flows into the filtration chamber 110. After filtration, the grinding fluid enters the water storage chamber 120. When the first outlet valve 320 is opened, the grinding fluid delivered by the water inlet assembly 200 enters the outlet pipe 330 through the first outlet valve 320 and is discharged. The second outlet control assembly 400 includes a second outlet valve 420. When the second outlet valve 420 is opened, the grinding fluid in the water storage chamber 120 enters the circulation chamber 130 through the second outlet valve 420. The circulation pump 500 is installed in the storage chamber 140 and can send the grinding fluid in the circulation chamber 130 into the grinding equipment. This filtration device serves as an auxiliary device for the grinding equipment. The grinding fluid is divided into two parts: one part participates in the grinding of materials in the grinding equipment, and the other part is filtered and cooled in this filtration device. After a certain period of use, the grinding fluid in the grinding equipment enters this filtration device for filtration and cooling, which removes dust and reduces the temperature of the grinding fluid before returning it to the grinding equipment. This improves the cleanliness of the ground product, extends the service life of the grinding fluid, and reduces operating costs.

[0025] In the application, the grinding liquid is discharged into the filtering cavity 110 by the water inlet assembly 200, or directly discharged from the first water outlet control assembly 300, and the discharge times are automatically recorded. The grinding liquid is filtered by the filtering cavity 110 to obtain clean grinding liquid into the water storage cavity 120, and the grinding liquid is cooled in the water storage cavity 120. When the grinding liquid needs to be injected into the circulating cavity 130, the second water outlet valve 420 is opened, and the grinding liquid in the water storage cavity 120 enters the circulating cavity 130 through the second water outlet valve 420, and finally the grinding liquid in the circulating cavity 130 is sent into the grinding equipment by the circulating pump 500. Therefore, the filtering device can automatically complete the functions of conveying, filtering, cooling and counting the discharge of the grinding liquid, improve the cleanliness of the product after grinding, prolong the use time of the grinding liquid, improve the grinding effect, and reduce the use cost. The first water outlet control assembly 300 is used to control the destination of the grinding liquid in the water inlet assembly 200, and the second water outlet control assembly 400 is used to control the communication between the water storage cavity 120 and the circulating cavity 130, which is simple in structure and convenient to operate.

[0026] As shown in Figure 1 and Figure 2 , the top of the filtering cavity 110 is a top plate, and the bottom is a filter plate 111. The top of the water storage cavity 120 is a filter plate 111, and the bottom is a first partition plate 121. The top of the circulating cavity 130 is a first partition plate 121, and the bottom is a second partition plate 131. The top of the storage cavity 120 is a second partition plate 131, and the bottom is a bottom plate 141. The shell 100 includes a top plate (not shown in the figure) and a bottom plate 141 connected to the four surrounding side plates. The shell 100 is divided into four independent spaces by the filter plate 111, the first partition plate 121 and the second partition plate 131, from top to bottom, which are the filtering cavity 110, the water storage cavity 120, the circulating cavity 130 and the storage cavity 140. The filtering cavity 110 is used for filtering the grinding liquid. The water storage cavity 120 is used for storing and cooling the grinding liquid. The circulating cavity 130 is used for providing the grinding liquid for the circulating pump 500.

[0027] Optionally, the filter plate 111 is a filter plate made of magnetic material, which can adsorb magnetic dust in the grinding liquid and filter out other impurities, thereby purifying the grinding liquid. The grinding liquid in the filtering cavity 110 is filtered by the filter plate 111 and then enters the water storage cavity 120.

[0028] As shown in Figure 2 and Figure 3 , the water inlet assembly 200 includes a water inlet pipe 210, a water inlet groove 220 and a baffle 230. The baffle 230 is fixedly connected to the filter plate 111. The water inlet groove 220 is installed in the filtering cavity 110. The water inlet pipe 210 is installed in the water inlet groove 220. The water inlet pipe 210 is communicated with the water inlet groove 220.

[0029] The lower end of the water inlet groove 220 has a gap with the baffle 230, and the baffle 230 is provided with a partition plate 240, which separates the baffle 230 and the filter plate 111. The partition plate 240 can provide a buffer space for the polishing liquid. When the first water outlet valve 320 is closed, the polishing liquid enters the water inlet groove 220 through the water inlet pipe 210, and then flows to the filter plate 111 through the gap between the water inlet groove 220 and the baffle 230. When the first water outlet valve 320 is opened, the polishing liquid enters the water inlet groove 220 through the water inlet pipe 210, and then directly flows out of the shell 100 through the water outlet pipe 330. The water inlet groove 220 can prevent the polishing liquid from splashing, and the polishing liquid can directly flow out through the water outlet pipe 330.

[0030] As shown in Figure 3 and Figure 4 The first water outlet control assembly 300 further comprises a first driving cylinder 310 connected to the first water outlet valve 320, and the first driving cylinder 310 can drive the first water outlet valve 320 to open and close.

[0031] The first water outlet valve 320 comprises a first closing plate and a first hole, and the piston rod of the first driving cylinder 310 is fixedly connected to the first closing plate. The baffle 230 is provided with a first hole, and the first closing plate can close the first hole under the action of the first driving cylinder 310. The water outlet pipe 330 is communicated with the first hole. Alternatively, the piston rod of the first driving cylinder 310 is connected to the first closing plate through a first connecting rod 340. When the first driving cylinder 310 drives the first closing plate to move downward and block the first hole, the polishing liquid enters the filter plate 111. When the first driving cylinder 310 drives the first closing plate to move upward, the first hole is opened, and the polishing liquid directly enters the water outlet pipe 330.

[0032] As shown in Figure 2 and Figure 3 The second water outlet control assembly 400 further comprises a second driving cylinder 410 connected to the second water outlet valve 420, and the second driving cylinder 410 can drive the second water outlet valve 420 to open and close.

[0033] The second water outlet valve 420 comprises a second closing plate and a second hole, the piston rod of the second driving cylinder 410 is fixedly connected to the second closing plate, the second hole is formed on the first partition plate 121, and the second closing plate can close the second hole under the action of the second driving cylinder 410. Optionally, the piston rod of the second driving cylinder 410 is connected to the second closing plate through a second connecting rod 440. The first partition plate 121 is fixedly installed with a bracket 430, and the second connecting rod 440 penetrates through the bracket 430, so that the stability of the operation of the second driving cylinder 410 is improved. Optionally, the first driving cylinder 310 and the second driving cylinder 410 are fixedly installed on the water inlet groove 220.

[0034] When the circulating cavity 130 needs to be supplemented with liquid, the second driving cylinder 410 drives the second closing plate to move upwards, the second closing plate moves away from the second hole, and the grinding liquid in the water storage cavity 120 flows into the circulating cavity 130 through the second hole; when the circulating cavity 130 does not need to be supplemented with liquid, the second driving cylinder 410 drives the second closing plate to move downwards, and the second closing plate blocks the second hole, so that the water storage cavity 120 and the circulating cavity 130 are completely isolated.

[0035] As shown in Figure 1 and Figure 2 The second partition plate 131 is provided with a water outlet 132, the circulating pump 500 is provided with a water inlet pipe 510 and a water return pipe 520, the water inlet pipe 510 is communicated with the water outlet 132, and the circulating pump 500 sucks the grinding liquid in the circulating cavity 130 through the water inlet pipe 510 and pumps the grinding liquid into the grinding equipment through the water return pipe 520. That is, the grinding liquid in the circulating cavity 130 enters the circulating pump 500 through the water outlet 132.

[0036] The operation method of the grinding liquid filtering device in the application comprises the following steps:

[0037] Step 1: when the automatic counting and discharging function needs to be performed, the first water outlet valve 320 is opened under the action of the first driving cylinder 310, and the grinding liquid in the water inlet assembly 200 directly flows out through the first water outlet valve 320 and the water outlet pipe 330;

[0038] Step 2: when the filtering function needs to be performed, the first water outlet valve 320 is closed under the action of the first driving cylinder 310, the grinding liquid in the water inlet assembly 200 enters the filter plate 111 and then seeps into the water storage cavity 120 below after being filtered by the filter plate 111;

[0039] Step 3: when the circulating cavity 130 needs to be supplemented with grinding liquid, the second water outlet valve 420 is opened under the action of the second driving cylinder 410, and the grinding liquid in the water storage cavity 120 flows into the circulating cavity 130 through the second water outlet valve 420;

[0040] Step 4: the circulating pump 500 sucks the grinding liquid in the circulating cavity 130 through the water inlet pipe 510 and pumps it into the grinding device through the water return pipe 520, and the grinding liquid is cooled in the filter device at the same time, so that the grinding liquid entering the grinding device again is clean and low-temperature grinding liquid, thereby prolonging the service life of the grinding liquid and improving the grinding effect.

[0041] It should be noted that, for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application.
