Description

Technical Field

[0001] This utility model relates to the technical field of zirconia production equipment, specifically a zirconia grinding device. Background Technology

[0002] Zirconia is the main oxide of zirconium. It is chemically inert and possesses properties such as high melting point, high resistivity, high refractive index, and low coefficient of thermal expansion. In chemical industrial production, it is widely used in the manufacture of high-temperature resistant materials, ceramic insulating materials, and ceramic opacifiers. Zirconia is a crystalline material at room temperature. When manufacturing other chemical products, it needs to be ground into fine powder, then added to other chemical raw materials, and undergoing a series of processing steps to produce the final chemical product. Existing grinding equipment cannot effectively screen materials, resulting in uneven material output. At the same time, existing grinding devices do not facilitate the entry of materials between the two grinding rollers, causing the device to run idle, which not only affects grinding efficiency but also increases energy consumption. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a zirconia grinding device, comprising a device box, a grinding base, grinding blocks, and screening plates. An inlet is provided on one side of the top of the device box. A hydraulic telescopic rod is bolted to the middle of the top of the device box. The output end of the hydraulic telescopic rod is connected to a fixed box inside the device box. A first motor is located inside the fixed box. A grinding base is bolted to the inner wall of the device box. A grinding block is placed on top of the grinding base. Fixing frames are symmetrically welded to the inner walls of both sides of the device box below the grinding base. Screening plates are provided on the surface of the fixing frames. A connecting frame is welded to the bottom of the grinding base above the two screening plates. An auxiliary screening component is provided at the bottom of the connecting frame. A conveying pipe is welded between the two fixing frames. A partition is welded to the inner wall of the device box on the surface of the conveying pipe. A qualified box is placed on top of the partition, and a non-qualified box is placed at the bottom of the inner cavity of the device box.

[0005] Preferably, a transmission rod is welded to the top of the grinding block, and the transmission rod is connected to the fixed box through a bearing. The output end of the first motor is fixedly connected to the transmission rod with screws, so that the grinding block can be rotated by the first motor to grind the zirconium oxide raw material. Furthermore, the gap between the grinding block and the grinding seat can be adjusted by the extension and retraction of the hydraulic telescopic cylinder, so that the material can enter the gap more smoothly, further improving the grinding effect and efficiency of the material, screening the material, and improving the uniformity of the material output.

[0006] Preferably, the equipment box has replacement openings on both sides of the fixed frame at corresponding locations. Replacement doors are installed in the replacement openings via hinges. The inner walls of both sides of the fixed frame have installation grooves. The two sides of the screening plate are fitted and slidably connected to the installation grooves, which facilitates the replacement of different screening plates according to actual screening specifications.

[0007] Preferably, the auxiliary screening component includes a mounting box welded to the bottom of the connecting frame. A second motor is installed on one side of the mounting box by screws. A rotating shaft is connected between the output end of the second motor and the inner wall of the mounting box. A connecting roller is fixedly welded to the surface of the rotating shaft.

The other end of the fixed rod is slidably connected and fitted in the reciprocating groove. After the zirconium oxide raw material ground by the grinding block and grinding seat enters the surface of the two screening plates, the second motor drives the connecting roller to rotate, causing the mounting block and brush on the fixed rod to move back and forth along the surface of the screening plate, so that the brush evenly disperses the zirconium oxide raw material on the surface of the screening plate to achieve a better screening effect.

[0008] Preferably, the connecting roller has limit grooves inside the mounting box on both sides, and the fixed rod has a limit slider welded to its surface. The limit slider is engaged and slidably connected with the limit groove.

[0009] Preferably, an electric door is installed at the top of the inner cavity of the conveying pipe, the bottom end of the conveying pipe is located above the non-combined phase, and the two fixing brackets are inclined, with the lower end of the two fixing brackets facing the conveying pipe.

[0012] Optimized screening function: The screening plate is set up to screen the ground material, which can improve the uniformity of the material output and solve the problem that the existing grinding equipment cannot effectively screen materials. The second motor in the auxiliary screening component drives the connecting roller to rotate, so that the brush moves back and forth on the surface of the screening plate, evenly dispersing the zirconium oxide raw material on the screening plate, further improving the screening effect.

[0013] For easy replacement of screening plates: Replacement openings and replacement doors are provided on both sides of the equipment box corresponding to the fixing frames. The mounting grooves on both sides of the fixing frames are fitted and slidably connected to the sides of the screening plates. This design allows for easy replacement of different screening plates according to actual screening specifications by opening the replacement doors, enhancing the applicability of the equipment.

[0014] Facilitates the handling of substandard materials: An electric door is installed at the top of the inner cavity of the conveying pipe, and the fixing frame is set at an angle, with the lower end facing the conveying pipe and the bottom end of the conveying pipe located above the substandard material box.

[0032] Furthermore, the qualified box 17 is located directly below the screening plate 4, and the front of the equipment box 1 is equipped with a hinged door 9. The door 9 corresponds to the positions of the qualified box 17 and the unqualified box 18, making it easy to open the door 9 to take out and place the qualified box 17 and the unqualified box 18.

[0033] Working principle:

[0034] Grinding preparation: Before starting the equipment, according to the required zirconium oxide powder particle size, open the replacement door 8 through the replacement ports 21 on both sides of the equipment box, and replace the appropriate screen plate 4 in the mounting groove 20 of the fixing frame 10. Afterwards, close the replacement door 8 to ensure the equipment is sealed.

[0035] Raw material grinding: Pour the zirconia raw material into the feed port 6 at the top of the equipment box 1. Activate the hydraulic telescopic rod 5, whose output end drives the fixed box 30 and the first motor 7 inside to descend, thereby adjusting the gap between the grinding block 3 and the grinding seat 2 to suit the grinding of the current raw material. Activate the first motor 7, whose output end drives the grinding block 3 connected to the transmission rod to rotate, grinding the zirconia raw material located on the grinding seat 2. During the grinding process, the gap between the grinding block 3 and the grinding seat 2 can be finely adjusted again through the hydraulic telescopic rod 5 according to the grinding condition of the raw material to ensure grinding effect and efficiency.

[0036] Auxiliary screening: The ground zirconia raw material falls onto the screening plate 4. At this time, the second motor 13 inside the mounting box 12 is started. The output end of the second motor 13 drives the rotating shaft 24 to rotate, which in turn causes the connecting roller 26 to rotate. The reciprocating groove 25 on the surface of the connecting roller 26 is engaged with one end of the fixed rod 19. When the connecting roller 26 rotates, the fixed rod 19 reciprocates along the connecting groove 28 on the side of the mounting box 12. A brush 14 is installed at the bottom of the mounting block 13 welded to the other end of the fixed rod 19. The brush 14 is in contact with the surface of the screening plate 4. With the reciprocating motion of the fixed rod 19, the brush 14 moves back and forth on the surface of the screening plate 4, evenly dispersing the zirconia raw material on the screening plate 4 to achieve a better screening effect.

[0037] Material classification and collection: Screening plate 4 screens the zirconia raw material. Raw materials that meet the particle size requirements fall through screening plate 4 into the qualified box 17 below; unqualified raw materials remain on screening plate 4. Since the fixing frame 10 is set at an angle, with the lower end facing the conveying pipe 11, the unqualified raw materials remaining on screening plate 4 will slide towards the conveying pipe 11 under the action of gravity. After the grinding work is completed, the electric door 15 at the top of the inner cavity of the conveying pipe 11 is opened, and the unqualified raw materials fall through the conveying pipe 11 into the unqualified box 18 below, completing the collection of unqualified raw materials.

[0038] Material Removal: After the work is completed, open the switch door 9 on the front of the equipment box 1. Since the switch door 9 corresponds to the qualified box 17 and the unqualified box 18, the qualified zirconium oxide powder in the qualified box 17 can be easily removed, and the unqualified raw materials in the unqualified box 18 can be processed.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
