The screen plate and the cover plate cover the top of the grinding barrel again according to the above reverse operation steps to complete the feeding;

[0017] Step 2: The rotating motor drives the rotating rod to rotate, so that the fixed rod and the scraper can stir the zirconium balls inside the grinding barrel, and the zirconium balls grind the materials. During the grinding process, multiple scrapers extend to different use positions, increasing the stirring effect of the device on the zirconium balls, improving the grinding effect of the device on the materials, and increasing the grinding efficiency of the device;

[0019] Step 4: After the material is ground, the grinding barrel rotates to a state where the opening faces downward, and the cover plate rotates to a state where it no longer abuts against the covering screen plate. The ground material in the grinding barrel will leak out of the grinding barrel through the screen holes and fall into a preset container outside the device. During the material discharge process, the rotating rod drives the fixed rod and the scraper to rotate, and the fixed rod and the scraper move the zirconium balls, and the materials between the gaps of the zirconium balls are moved, thereby increasing the falling speed and making the falling process of the materials smoother.

[0020] Step 5: During the material discharge process, the scraper can knock the screen plate. This operation method can prevent the screen holes from being blocked, which will affect the falling of the materials and increase the convenience of the device. The scraper abuts against the inner wall of the grinding barrel, the rotating rod rotates, and the fan connected to the check valve blows air. The scraper can scrape the inner wall of the grinding barrel. Combined with the fan blowing air inside the device, the residual material on the inner wall of the grinding barrel is scraped off, increasing the material discharge rate of the device and completing the cleaning of the inner wall of the grinding barrel.

[0021] Step six: After the use of the device is finished, the outer side of the connecting pipe is connected to the water pipe, and the grinding barrel is rotated to the use state with the opening facing downward. The water pipe injects a preset amount of clean water into the grinding barrel. The rotating rod rotates, and the fixed rod and the scraper can stir the zirconium balls inside the grinding barrel. Combined with the scraper scraping the inner wall of the grinding barrel, the inside of the grinding barrel and the zirconium balls are cleaned. After cleaning, the sewage can be discharged directly from the connecting pipe. The cover plate is rotated to the use state without covering the screen plate. The rotating rod rotates to make the fixed rod and the scraper stir the zirconium balls. Combined with the use effect of blowing air at the check valve, the cleaned zirconium balls and the inside of the grinding barrel can be quickly dried, which increases the convenience of using the device.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, a check valve is provided, and air with a preset wind force is blown to the grinding barrel through the check valve, so that the zirconium balls and materials inside the grinding tank can be purged, which can prevent a large amount of materials from sticking to the wall and agglomerating at the bottom, and can also cool the materials while causing them to tumble, so that the materials are evenly ground, greatly improving the production quality of the device;

[0024] After the device finishes cleaning the zirconium balls and the inside of the grinding barrel, the device blows air into the inside of the grinding barrel through the check valve, so that the cleaned zirconium balls and the inside of the grinding barrel can be quickly dried, which increases the convenience of using the device.

[0025] In the present invention, by providing a connecting pipe, when the device is grinding the material, when the check valve is blowing air, the connecting pipe is opened, which can balance the pressure inside the grinding barrel, prevent the pressure inside the grinding barrel from increasing and affecting the grinding effect of the device, and also ensure the normal operation of the check valve blowing air into the grinding barrel.

[0026] After the device is used, the outer side of the connecting pipe is connected to the water pipe, and then the grinding barrel is rotated to the use state with the opening facing downward. The water pipe injects a preset amount of clean water into the grinding barrel to complete the cleaning of the inside of the grinding barrel and the zirconium balls. After cleaning, the sewage can be discharged directly from the connecting pipe, which increases the convenience of using the device.

[0027] In the present invention, by providing a fixed rod and a scraper, during the grinding process, the second electric slider slides in the second slide groove, so that multiple scrapers can be extended to different use positions. Through this operation mode, the scraper can stir the zirconium balls at different positions, which can increase the stirring effect of the device on the zirconium balls, thereby improving the grinding effect of the device on the material and increasing the grinding efficiency of the device;

[0028] After the material is ground and discharged, the rotating rod drives the fixed rod and the scraper to rotate. The fixed rod and the scraper move the zirconium balls, which can move the materials between the gaps of the zirconium balls, increase the falling speed, and make the falling process of the materials smoother.

[0029] During the material unloading process, the first electric slider slides in the first chute, so that the scraper can knock the screen plate. This operation method can prevent the screen holes from being blocked, which affects the falling of the materials and increases the convenience of using the device.

[0030] By moving the movable rod on the fixed rod, the scraper is brought into contact with the inner wall of the grinding barrel. Then, by rotating the rotating rod, the fan connected to the check valve blows air, so that the scraper can scrape the inner wall of the grinding barrel. Combined with the blowing of the fan inside the device, this operation method can scrape off the residual material on the inner wall of the grinding barrel, increase the material discharge rate of the device, and complete the cleaning of the inner wall of the grinding barrel.

[0031] During the cleaning process of the zirconium balls, the agitation of the zirconium balls by the fixed rod and the scraper, and the scraping of the inner wall of the grinding barrel by the scraper can improve the cleaning effect of the device on the zirconium balls and the grinding barrel, and increase the functional stability of the device.

[0054] As a technical optimization solution of the present invention, a grinding method of a vertical sand mill is provided, which is applicable to the above-mentioned grinding jar, and the grinding method further comprises the following steps:

[0055] Step 1: The electric telescopic rod 8 drives the cover plate 10 to extend upward to a preset height position, the third rotary motor 14 drives the cover plate 10 to rotate to a preset position, the electric lifting rod 29 drives the screen plate 7 to rise to a preset height position, and the second rotary motor 13 drives the screen plate 7 to rotate to the opposite direction of the cover plate 10. The staff adds different zirconium balls to the inside of the grinding barrel 2 according to the grinding requirements, and fills the materials to be ground into the grinding barrel 2. The screen plate 7 and the cover plate 10 cover the top of the grinding barrel 2 again according to the above-mentioned reverse operation steps to complete the feeding;

[0056] Step 2: The rotating motor 3 drives the rotating rod 15 to rotate, so that the fixed rod 17 and the scraper 18 can stir the zirconium balls inside the grinding barrel 2, and the zirconium balls grind the materials. During the grinding process, multiple scrapers 18 extend to different use positions, which increases the stirring effect of the device on the zirconium balls, improves the grinding effect of the device on the materials, and increases the grinding efficiency of the device;

[0057] Step 3: The solenoid valve inside the connecting pipe 11 is opened, and the fan connected to the check valve 4 is started, and the preset wind force is blown to the grinding barrel 2 through the check valve 4 to purge the zirconium balls and materials inside the grinding tank to prevent a large amount of materials from sticking to the wall and agglomerating at the bottom, and the materials can be cooled and rolled at the same time to achieve uniform grinding of the materials;

[0058] Step 4: After the grinding of the material is completed, the grinding barrel 2 is rotated to a use state with the opening facing downward, and the cover plate 10 is rotated to a use state where it no longer abuts against the covering screen plate 7. The ground material in the grinding barrel 2 will leak out of the grinding barrel 2 through the screen hole 16 and fall into a preset container outside the device. During the material discharge process, the rotating rod 15 drives the fixed rod 17 and the scraper 18 to rotate, and the zirconium balls are moved by the fixed rod 17 and the scraper 18 to move the materials between the gaps of the zirconium balls, thereby increasing the falling speed and making the falling process of the materials smoother.

[0059] Step 5: During the material discharge process, the scraper 18 can knock the screen plate 7. This operation mode can prevent the screen hole 16 from being blocked, which will affect the falling of the material and increase the convenience of the device. The scraper 18 abuts against the inner wall of the grinding barrel 2, the rotating rod 15 rotates, and the fan connected to the check valve 4 blows air. The scraper 18 can scrape the inner wall of the grinding barrel 2. Combined with the blowing of the fan inside the device, the residual material on the inner wall of the grinding barrel 2 is scraped off, the material discharge rate of the device is increased, and the inner wall of the grinding barrel 2 is cleaned;

[0060] Step six: After the use of the device is finished, the outer side of the connecting pipe 11 is connected to the water pipe, and the grinding barrel 2 is rotated to the use state with the opening facing downward. The water pipe injects a preset amount of clean water into the interior of the grinding barrel 2, and the rotating rod 15 rotates. The fixed rod 17 and the scraper 18 can stir the zirconium balls inside the grinding barrel 2. Combined with the scraper 18 scraping the inner wall of the grinding barrel 2, the inside of the grinding barrel 2 and the zirconium balls are cleaned. After cleaning, the sewage can be directly discharged from the connecting pipe 11, and the cover plate 10 is rotated to the use state without covering the sieve plate 7. The rotating rod 15 rotates to make the fixed rod 17 and the scraper 18 stir the zirconium balls. Combined with the use effect of blowing at the check valve 4, the cleaned zirconium balls and the interior of the grinding barrel 2 can be quickly dried, which increases the convenience of using the device.

[0061] When the present invention is in use, the electrical equipment in the device is powered by an external power supply through a wire. The device controls the electrical equipment in the device by setting a control system. The check valve 4 is connected to a preset fan outside the device through a conduit, and the reserved length of the conduit is sufficient for the grinding barrel 2 to operate. A solenoid valve is provided inside the connecting pipe 11, and the connecting pipe 11 can be connected to an external water pipe. The interior of the grinding barrel 2 is provided with zirconium balls, and then the rotating rod 15 is rotated to make the zirconium balls grind the material. This is an existing mature technology, so it will not be elaborated on in detail. A sealing gasket is provided at the position where the cover plate 10 abuts the sieve plate 7, and a sealing gasket is provided at the abutment between the sieve plate 7 and the fixing ring 5. The specifications of the sieve plate 7 can be replaced according to different grinding requirements.

[0062] When the material needs to be ground, the electric telescopic rod 8 drives the cover 10 to extend upward to a preset height position, and then the third rotating motor 14 drives the cover 10 to rotate to a preset position, and the electric lifting rod 29 drives the screen plate 7 to rise to a preset height position, and the second rotating motor 13 drives the screen plate 7 to rotate to the opposite direction of the cover 10. At this time, the top of the grinding barrel 2 is opened, and the staff can add different zirconium balls to the inside of the grinding barrel 2 according to the grinding requirements. The staff adds the material to be ground into the inside of the grinding barrel 2, and then the screen plate 7 and the cover 10 cover the top of the grinding barrel 2 again according to the above-mentioned reverse operating steps to complete the feeding.

[0063] Then, the rotating rod 15 is driven to rotate by rotating the motor 3, so that the fixed rod 17 and the scraper 18 can stir the zirconium balls inside the grinding barrel 2, so that the zirconium balls grind the materials. During the grinding process, the second electric slider 26 slides in the second slide groove 25, so that the multiple scrapers 18 can extend to different use positions. Through this operation mode, the scraper 18 can stir the zirconium balls at different positions, which can increase the stirring effect of the device on the zirconium balls, thereby improving the grinding effect of the device on the materials and increasing the grinding efficiency of the device.

[0064] During the grinding process of the device, the solenoid valve inside the connecting pipe 11 is opened, and the fan connected to the check valve 4 is started. The preset wind force is blown to the grinding barrel 2 through the check valve 4, so that the zirconium balls and materials inside the grinding tank can be purged, which can prevent a large amount of material from sticking to the wall and agglomerating at the bottom. It can also cool the material and make it tumble, so that the material is evenly ground, which greatly improves the production quality of the device. After the preset time of wind blowing, the fan connected to the check valve 4 stops blowing, and the solenoid valve installed on the connecting pipe 11 is closed again.

[0065] After the material is ground, the first rotating motor 12 drives the grinding barrel 2 to rotate, so that the grinding barrel 2 rotates to a use state with the opening facing downward, and then the cover plate 10 rotates to a use state where it no longer abuts against the covering screen plate 7. At this time, the ground material in the grinding barrel 2 will leak out of the grinding barrel 2 through the screen hole 16 and fall into a preset container outside the device. During the material discharge process, the rotating rod 15 drives the fixed rod 17 and the scraper 18 to rotate, and the fixed rod 17 and the scraper 18 move the zirconium balls, which can move the materials between the gaps of the zirconium balls, increase the falling speed, and make the falling process of the materials smoother.

[0066] During the material unloading process, the first electric slider 22 slides in the first chute 21, so that the scraper 18 can knock the screen plate 7. This operation mode can prevent the screen hole 16 from being blocked, which affects the falling of the material and increases the convenience of using the device. The movable rod 23 moves on the fixed rod 17 so that the scraper 18 abuts against the inner wall of the grinding barrel 2. Then, the rotating rod 15 rotates and the fan connected to the check valve 4 blows air, so that the scraper 18 can scrape the inner wall of the grinding barrel 2. Combined with the blowing of the fan inside the device, this operation mode can scrape off the residual material on the inner wall of the grinding barrel 2, increase the unloading rate of the device, and complete the cleaning of the inner wall of the grinding barrel 2.

[0067] After the device is used, the outer side of the connecting pipe 11 is connected to the water pipe, and then the grinding barrel 2 is rotated to the use state with the opening facing downward, and the water pipe injects a preset amount of clean water into the grinding barrel 2. Then, by rotating the rotating rod 15, the fixed rod 17 and the scraper 18 can stir the zirconium balls inside the grinding barrel 2. Combined with the scraper 18 scraping the inner wall of the grinding barrel 2, the inside of the grinding barrel 2 and the zirconium balls can be cleaned. After the cleaning is completed, the sewage can be directly discharged from the connecting pipe 11;

[0068] Then the cover plate 10 is rotated to a usage state where it does not cover the sieve plate 7. At this time, the rotating rod 15 is rotated to cause the fixed rod 17 and the scraper 18 to stir the zirconium balls. Combined with the use effect of blowing air at the check valve 4, the cleaned zirconium balls and the interior of the grinding barrel 2 can be quickly dried, thereby increasing the convenience of using the device.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A grinding method for a vertical sand mill, characterized in that: The grinding method is applicable to the grinding jar in claim 9, and the grinding method further comprises the following steps: Step 1: The electric telescopic rod (8) drives the cover plate (10) to extend upward to a preset height position, the third rotary motor (14) drives the cover plate (10) to rotate to a preset position, the electric lifting rod (29) drives the screen plate (7) to rise to a preset height position, the second rotary motor (13) drives the screen plate (7) to rotate to a direction opposite to the cover plate (10), the staff adds different zirconium balls into the grinding barrel (2) according to the grinding requirements, and the material to be ground is added into the grinding barrel (2), the screen plate (7) and the cover plate (10) are covered on the top of the grinding barrel (2) again according to the above reverse operation steps to complete the material addition; Step 2: The rotating motor (3) drives the rotating rod (15) to rotate, so that the fixed rod (17) and the scraper (18) can stir the zirconium balls inside the grinding barrel (2), and the zirconium balls grind the materials. During the grinding process, multiple scrapers (18) extend to different use positions, thereby increasing the stirring effect of the device on the zirconium balls, improving the grinding effect of the device on the materials, and increasing the grinding efficiency of the device; Step 3: The solenoid valve inside the connecting pipe (11) is opened, and the fan connected to the check valve (4) is started, and air with a preset wind force is blown to the grinding barrel (2) through the check valve (4), so as to purge the zirconium balls and materials inside the grinding tank, thereby preventing a large amount of materials from sticking to the wall and agglomerating at the bottom, and also cooling the materials while causing them to tumble, so as to achieve uniform grinding of the materials; Step 4: After the grinding of the material is completed, the grinding barrel (2) is rotated to a state of use with the opening facing downward, and the cover plate (10) is rotated to a state of use where it no longer abuts against the covering screen plate (7). The ground material in the grinding barrel (2) will leak out of the grinding barrel (2) through the screen hole (16) and fall into a container preset outside the device. During the material discharge process, the rotating rod (15) drives the fixed rod (17) and the scraper (18) to rotate, and the zirconium balls are moved by the fixed rod (17) and the scraper (18), so that the material between the gaps of the zirconium balls is moved, thereby increasing the falling speed and making the falling process of the material smoother. Step 5: During the material discharge process, the scraper (18) can knock the screen plate (7). This operation method can prevent the screen hole (16) from being blocked, which would affect the falling of the material and increase the convenience of the device. The scraper (18) abuts against the inner wall of the grinding barrel (2), the rotating rod (15) rotates, and the fan connected to the check valve (4) blows air. The scraper (18) can scrape the inner wall of the grinding barrel (2). Combined with the air blowing of the fan inside the device, the material remaining on the inner wall of the grinding barrel (2) is scraped off, thereby increasing the material discharge rate of the device and completing the cleaning of the inner wall of the grinding barrel (2). Step 6: After the device is used, the outer side of the connecting pipe (11) is connected to the water pipe, the grinding barrel (2) is rotated to a use state with the opening facing downward, the water pipe injects a preset amount of clean water into the grinding barrel (2), the rotating rod (15) rotates, the fixed rod (17) and the scraper (18) can stir the zirconium balls inside the grinding barrel (2), and the scraper (18) scrapes the inner wall of the grinding barrel (2) to complete the cleaning of the grinding barrel (2) and the zirconium balls. After the cleaning is completed, the sewage can be directly discharged from the connecting pipe (11), the cover plate (10) is rotated to a use state that does not cover the screen plate (7), the rotating rod (15) rotates so that the fixed rod (17) and the scraper (18) stir the zirconium balls, and the use effect of blowing air at the check valve (4) makes the zirconium balls and the inside of the grinding barrel (2) after cleaning achieve a quick drying effect, thereby increasing the convenience of use of the device.
