[0017] The present invention also discloses a method for using a high-speed centrifugal separation device based on grinding fluid purification treatment, which specifically includes the following steps:

[0018] Step 1: The user powers several electromagnets in a set of filter elements, and introduces the grinding fluid to be processed into the housing through the injection pipe, the second three-way valve, and the conduit. The filter cover in the housing filters large particles of impurities in the grinding fluid. The grinding fluid falls on the dredging seat and is introduced into the centrifuge through the liquid pipe. During this process, the magnetic force generated by the electromagnet adsorbs the metal chips in the grinding fluid on the dredging seat. The centrifuge centrifuges the grinding fluid. The liquid level sensor detects the liquid level on the inner side of the housing near the upper side of the screening element. When the screening element detects that the liquid level reaches the warning value, the second three-way valve is reversed, and the grinding fluid is then injected into another set of filter elements through the second three-way valve.

[0019] Step 2: in step 1, after the second three-way valve is reversed, the grinding fluid in the original filter element is discharged, and the first cylinder in the first blanking part drives the first telescopic plate to retract. At this time, the casing is connected to the inside of the shell, and the motor drives the dredging seat through the bevel gear assembly and the sleeve. The second cross shaft, the filter cover, the rotating frame, and the top block rotate. Under the action of the spring assembly, the sliding rod presses the scraper tightly against the filter cover. During the rotation of the filter cover, the scraper scrapes the large particles of impurities retained on the filter cover to promote the shedding of impurities. Under the action of the centrifugal force of the filter cover, the large particles of impurities are finally introduced into the first recovery box through the casing. The motor is turned off, and the height of the first cross shaft, the mounting block, the rotating rod, the electromagnet, and the dredging seat is adjusted by the hydraulic cylinder assembly, so that the several dredging rods on the dredging seat can push out the impurities retained in the filter holes in the filter cover to play a dredging role.

[0020] Step three: After the filter cover is dredged in step two, reset each link and use the hydraulic cylinder assembly to drive the lifting plate, the first cross shaft, the mounting block, the rotating rod, the electromagnet and the dredge seat to move downward to a suitable height, so that the right end of the dredge seat moves to the left side of the second telescopic plate. The second telescopic plate is telescopically adjusted by the second cylinder, and the power supply to the electromagnet is stopped. The metal chips retained on the dredge seat gradually lose adsorption and slide down, and the dredge seat is driven to rotate again. Under the action of centrifugal force, the metal chips on the dredge seat are gradually introduced into the second recovery box through the end of the second telescopic plate and the discharge chute.

[0021] Preferably, in step 2, the dredging seat drives the second cross shaft to slide upward along the filter cover, the second cross shaft passes through the top block to push the scraper, and the scraper drives the slide rod to move upward and compress the spring in the spring assembly.

[0022] Beneficial effects

[0023] The present invention provides a high-speed centrifugal separation device and method based on grinding fluid purification. Compared with the existing technology, it has the following advantages:

[0024] (1) The high-speed centrifugal separation device and method based on grinding fluid purification treatment, by arranging a second three-way valve and two groups of filter elements in the device, allowing the second three-way valve, two groups of shells, conduits, liquid level sensors, and filter covers to cooperate with each other to achieve filtering of large-particle impurities in the grinding fluid and after a sufficient amount of large-particle impurities are gathered on the upper side of the filter cover, by switching the liquid flow to replace the filter end, reducing the interruption of the filtering operation due to the cleaning of the filter end and reducing the processing efficiency of the grinding fluid, allowing the motor, bevel gear assembly, sleeve, hydraulic cylinder assembly, lifting plate, first cross shaft, mounting block, rotating rod, electromagnet, dredging seat, rotating frame, filter cover, second cross shaft, and scraper to cooperate with each other to achieve the stripping of large-particle impurities retained on the surface of the filter end, and having the function of dredging and exporting impurities retained in the filter holes of the filter end, improving the cleaning efficiency while preventing the subsequent filtering operation from being affected by the continuous retention of large-particle impurities at the filter end. In addition, it has the function of adsorbing and exporting metal chips in the filtered grinding fluid, thereby reducing the burden of subsequent centrifugal operation of the centrifuge and extending the service life of the device.

[0025] (2) The high-speed centrifugal separation device and method based on grinding fluid purification treatment is characterized in that a scraper is set in the device. Under the action of the spring assembly, the sliding rod presses the scraper tightly against the filter cover. During the rotation of the filter cover, the scraper scrapes the large particles of impurities retained on the filter cover, promoting the impurities to fall off, thereby improving the stripping efficiency of the impurities retained on the upper surface of the filter end. In the subsequent dredging process of the filter cover, the dredging seat drives the second cross shaft to slide upward along the filter cover, and the second cross shaft pushes the scraper through the top block to separate the scraper from the filter cover, preventing the scraper from being retained on the surface of the filter cover and affecting the dredging operation, thereby enhancing the dredging effect.

[0026] (3) The high-speed centrifugal separation device and method based on grinding fluid purification treatment, by setting a cleaning part in the device, the water pump draws external water source and flushes the upper surface of the filter cover through the first three-way valve, the bifurcated pipe, and the two groups of water spray plates, and the water passing through the filter cover flushes the upper surface of the dredging seat, promoting the residual material attached to the upper surface of the filter cover and the iron filings attached to the dredging seat to flow out with the water, thereby improving the cleaning effect. The first three-way valve can be reversed to achieve the switching of the water flow direction, and the water pumped by the water pump is sprayed and cleaned on the inner side of the other group of filter elements through the first three-way valve, the other group of bifurcated pipes, and the two groups of water spray plates, thereby reducing the subsequent cleaning steps.

[0049] The present invention also discloses a high-speed centrifugal separation device and method based on grinding fluid purification treatment, which specifically includes the following steps:

[0050] Step 1: The user powers the electromagnets 3435 in a group of filter elements 3, and introduces the grinding fluid to be processed into the housing 31 through the injection pipe, the second three-way valve 5, and the conduit 32. The filter cover 3453 in the housing 31 filters the large particles of impurities in the grinding fluid, and then the grinding fluid falls on the dredging seat 344 and is introduced into the centrifuge 2 through the liquid pipe 6. During this process, the magnetic force generated by the electromagnet 3435 adsorbs the metal chips in the grinding fluid on the dredging seat 344. The centrifuge 2 centrifuges the grinding fluid to purify the grinding fluid. The centrifuge 2 is a prior art, and its internal specific structure and working principle are not described in detail. At the same time, the liquid level sensor 33 detects the liquid level on the upper side of the screening element 345 inside the housing 31. When the screening element 345 detects that the liquid level reaches the warning value, it means that a large number of large particles of impurities are gathered on the upper side of the screening element 345, so the second three-way valve 5 is reversed. At this time, the grinding fluid is injected into another group of filter elements 3 through the second three-way valve 5;

At this time, the housing 361 is connected to the interior of the shell 31, and the motor 3411 is started. The motor 3411 drives the dredging seat 344 through the bevel gear assembly 3412 and the sleeve 3413, and the second cross shaft 3454, the filter cover 3453, the rotating frame 3452, and the top block 3455 rotate. Under the action of the spring assembly 351, the sliding rod 352 presses the scraper 353 tightly against the filter cover 3453. During the rotation of the filter cover 3453, the scraper 353 scrapes the large particles of impurities retained on the filter cover 3453 to promote the falling of the impurities. Under the action of the centrifugal force of the filter cover 3453, the large particles of impurities are finally introduced into the first recovery box 364 through the casing 361. After the processing is completed, the motor 3411 is turned off, and the height of the first cross shaft 3432, the mounting block 3433, the rotating rod 3434, the electromagnet 3435, and the dredging seat 344 are adjusted by the hydraulic cylinder assembly 342, so that the dredging rods on the dredging seat 344 can push out the impurities retained in the filter holes in the filter cover 3453, thereby playing a dredging role. The pushed-out impurities slide down the inclined surface of the filter cover 3453.

[0052] Step 3: After the filter cover 3453 is dredged in step 2, reset all links and use the hydraulic cylinder assembly 342 to drive the lifting plate 3431, the first cross shaft 3432, the mounting block 3433, the rotating rod 3434, the electromagnet 3435 and the dredging seat 344 to move downward to a suitable height, so that the right end of the dredging seat 344 moves to the left side of the second telescopic plate 372, and the second telescopic plate 372 is telescoped and adjusted by the second cylinder 371, and the power supply to the electromagnet 3435 is stopped. The dredging seat 344 is The retained metal chips gradually lose their adsorption and slide down, re-driving the dredging seat 344 to rotate. Under the action of centrifugal force, the metal chips on the dredging seat 344 are gradually introduced into the second recovery box 373 through the end of the second telescopic plate 372 and the discharge chute. The water pump 41 is turned on, and the water pump 41 draws water from the external source and flushes the upper surface of the filter cover 3453 through the first three-way valve 43, the bifurcated pipe 44, and the two sets of water spray plates 45. The water passing through the filter cover 3453 flushes the upper surface of the dredging seat 344, thereby improving the cleaning effect.

[0053] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art. In step two, the dredging seat 344 drives the second cross shaft 3454 to slide upward along the filter cover 3453, and the second cross shaft 3454 pushes the scraper 353 through the top block 3455. The scraper 353 drives the slide rod 352 to move upward and compresses the spring in the spring assembly 351 to prevent the scraper 353 from affecting the dredging operation. The compressed spring in the spring assembly 351 helps to promote the reset of the slide rod 352 and the scraper 353.

The filter cover (3453) in the housing (31) filters the large particles of impurities in the grinding fluid. The grinding fluid falls on the dredging seat (344) and is introduced into the centrifuge (2) through the liquid pipe (6). During this process, the magnetic force generated by the electromagnet (3435) adsorbs the metal chips in the grinding fluid onto the dredging seat (344). The centrifuge (2) centrifuges the grinding fluid. The liquid level sensor (33) detects the liquid level on the upper side of the inner side of the housing (31) near the screening element (345). When the screening element (345) detects that the liquid level reaches the warning value, the second three-way valve (5) is reversed. At this time, the grinding fluid is injected into another group of filter elements (3) through the second three-way valve (5). Step 2: In step 1, after the second three-way valve (5) is reversed, the grinding fluid in the original filter element (3) is completely discharged, and the first cylinder (362) in the first blanking member (36) drives the first telescopic plate (363) to retract.

Under the action of the spring assembly (351), the sliding rod (352) presses the scraper (353) against the filter cover (3453). During the rotation of the filter cover (3453), the scraper (353) scrapes the large particles of impurities retained on the filter cover (3453) to promote the falling of the impurities. Under the action of the centrifugal force of the filter cover (3453), the large particles of impurities are finally introduced into the first recovery box (364) through the housing (361). The motor (3411) is turned off, and the height of the first cross shaft (3432), the mounting block (3433), the rotating rod (3434), the electromagnet (3435), and the dredging seat (344) are adjusted by the hydraulic cylinder assembly (342), so that the dredging rods on the dredging seat (344) can push out the impurities retained in the filter holes in the filter cover (3453), thereby playing a dredging role. Step 3: In step 2, after the filter cover (3453) is dredged, each link is reset, and the hydraulic cylinder assembly (342) drives the lifting plate (3431), the first cross shaft (3432), the mounting block (3433), the rotating rod (3434), the electromagnet (3435), and the dredging seat (344) to move downward to a suitable height, so that the right end of the dredging seat (344) moves to the left side of the second telescopic plate (372), and the second telescopic plate (372) is telescopically adjusted by the second cylinder (371).
