Description

Technical Field

[0001] This utility model relates to the field of zirconium dioxide processing technology, specifically to a high-efficiency screening device for zirconium dioxide processing. Background Technology

[0002] Zirconium dioxide is the main oxide of zirconium. Under normal conditions, it is a white, odorless, and tasteless crystal, and is sparingly soluble in water, hydrochloric acid, and dilute sulfuric acid. Its chemically inert nature, coupled with its high melting point, high resistivity, high refractive index, and low coefficient of thermal expansion, makes it an important high-temperature resistant material, ceramic insulating material, and ceramic opacifier. It is also a primary raw material for artificial drills.

[0003] In the processing of zirconium dioxide, screening is required to obtain uniformly sized particles for subsequent use. The screening plates and frames are typically secured with multiple bolts. When replacing the screening plate—that is, selecting a screen with the appropriate size—tools are needed to loosen and tighten these bolts, removing the old screening plate and installing the new one. This process is time-consuming and consequently affects material processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency screening device for zirconium dioxide processing, which replaces the traditional method of using bolts to install and fix the screening plate, thus shortening the installation time and improving the material processing efficiency, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency screening device for zirconium dioxide processing, comprising a screening frame and a screening plate connected within the screening frame. The screening frame is connected to a positioning mechanism for positioning the screening plate. The positioning mechanism includes four pressing blocks, two moving plates, two pulling plates, and a spring. The pressing blocks are movably connected to the screening frame, and the ends of the pressing blocks are fixedly connected to the moving plates. The ends of the pulling plates are connected to the moving plates. The spring is used to drive the two pulling plates away from each other. A driving mechanism is connected to the side of the screening frame for driving the two pulling plates closer to each other.

[0006] Preferably, the positioning mechanism further includes two grooves, four guide grooves, and guide posts. The grooves are disposed in the screening frame, the guide grooves are disposed in the grooves, the moving plate is slidably connected to the guide grooves, and the guide posts are used to guide the two pull plates.

[0007] Preferably, both ends of the guide post are inserted into the pull plate, and the guide post and the pull plate are slidably connected.

[0008] Preferably, the spring is sleeved on the guide post, and both ends of the spring are connected to the pull plate.

[0009] Preferably, the screening frame is provided with a placement slot that matches the screening plate, and the placement slot is connected to four positioning posts, which are connected to the limiting holes provided on the screening plate.

[0010] Preferably, the driving mechanism includes a U-shaped plate, a cam, a handle, and a positioning bolt. The U-shaped plate is slidably connected to the screening frame, the cam is rotatably connected to the screening frame, and the cam is used to drive the U-shaped plate to move downward. The U-shaped plate is connected to two pull plates, the end of the handle is connected to the cam, and the positioning bolt is used to lock and fix the cam.

[0011] Preferably, the positioning bolt is threaded to the handle, and the side of the screening frame is provided with a connecting groove, the end of the positioning bolt being connected to the connecting groove.

[0013] Preferably, the filter box is detachably connected to a baffle, and a handle is connected to the side of the baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a positioning mechanism and a driving mechanism, rotates the handle to drive the cam to rotate, so that the protruding end of the cam presses against the U-shaped plate. The U-shaped plate applies a downward pushing force to the two pull plates, which can drive the two pull plates to move closer to each other. The pull plates pull the corresponding moving plates to move, and simultaneously drive the pressing block to move, so that the pressing block presses against the top of the screening plate, thereby locking and fixing the screening plate and improving the stability of the connection between the screening plate and the screening frame. Rotating the handle drives the cam to rotate, so that the protruding end of the cam separates from the U-shaped plate. The compressed spring drives the two pull plates to move away from each other, the U-shaped plate moves up, and the pull plates push the moving plates back, so that the pressing block returns to its position and separates from the screening plate, thereby realizing the rapid loosening of the screening plate, which is convenient for the disassembly and assembly of the screening plate. Screening plates with different aperture sizes can be selected according to actual needs, replacing the traditional method of using bolts to install and fix the screening plate, shortening the installation time and improving the processing efficiency of materials.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 This utility model provides a high-efficiency screening device for zirconium dioxide processing, including a screening frame 1 and a screening plate 2 connected within the screening frame 1. The screening frame 1 is connected to a positioning mechanism for positioning the screening plate 2. The positioning mechanism includes four pressing blocks 3, two moving plates 7, two pulling plates 6, and a spring 16. The pressing blocks 3 are slidably connected to the screening frame 1 to improve the stability of the reciprocating movement of the pressing blocks 3. One end of the pressing block 3 is provided with an inclined surface to facilitate the connection between the pressing block 3 and the screening plate 2. The other end of the pressing block 3 is fixedly connected to the moving plate 7. The end of the pulling plate 6 is connected to the moving plate 7. The spring 16 is used to drive the two pulling plates 6 away from each other. A driving mechanism for driving the two pulling plates 6 to move closer to each other is connected to the side of the screening frame 1.

[0024] During installation of the screening plate 2, rotating the handle 12 drives the cam 14 to rotate, causing the protruding end of the cam 14 to press against the U-shaped plate 9. This causes the U-shaped plate 9 to exert a downward pushing force on the two pull plates 6, driving the two pull plates 6 closer together, and the spring 16 is gradually compressed. The pull plates 6 pull the corresponding moving plates 7 to move, synchronously driving the pressing blocks 3 to move, so that the pressing blocks 3 press firmly against the top of the screening plate 2, thereby locking and fixing the screening plate 2 and improving the stability of the connection between the screening plate 2 and the screening frame 1.

[0025] The positioning mechanism also includes two grooves 8, four guide grooves 18, and guide posts 15. The grooves 8 are set in the screening frame 1, the guide grooves 18 are set in the grooves 8, the moving plate 7 is slidably connected to the guide grooves 18, and the guide posts 15 are used to guide the two pull plates 6. The cooperation of the grooves 8 and the guide grooves 18 provides a good guiding effect for the moving plate 7.

[0026] The two ends of the guide post 15 are inserted into the pull plate 6, and the guide post 15 is slidably connected to the pull plate 6. When the two pull plates 6 move closer or further apart, the guide post 15 slides relative to the pull plate 6, thereby improving the stability of the movement of the pull plate 6.

[0027] Spring 16 is fitted onto guide post 15, and both ends of spring 16 are connected to pull plate 6.

[0028] The screening frame 1 is provided with a placement slot 17 that matches the screening plate 2. The placement slot 17 is connected to four positioning posts 4, which are connected to the limiting holes provided on the screening plate 2. When installing the screening plate 2, the screening plate 2 is placed into the placement slot 17, which provides support for the screening plate 2. The positioning posts 4 pass through the limiting holes to initially limit the position of the screening plate 2.

[0029] The driving mechanism includes a U-shaped plate 9, a cam 14, a handle 12, and a positioning bolt 13. The U-shaped plate 9 is slidably connected to the screening frame 1, improving the stability of its lifting and lowering. The cam 14 is rotatably connected to the screening frame 1, ensuring stable rotation. The cam 14 drives the U-shaped plate 9 to move downwards. The U-shaped plate 9 is connected to two pull plates 6. The end of the handle 12 is connected to the cam 14, and the positioning bolt 13 is used to lock and fix the cam 14. When the pressing block 3 presses against the screening plate 2, the positioning bolt 13 locks the handle 12, limiting the movement of the cam 14 and preventing the pressing block 3 from moving, thus effectively limiting the movement of the screening plate 2. When the screening plate 2 needs to be loosened, first operate the positioning bolt 13 to loosen the handle 12, then rotate the handle 12 in the following direction: Figure 3 The arrow points to the center, which synchronously drives the cam 14 to rotate, causing the protruding end of the cam 14 to separate from the U-shaped plate 9. The compressed spring 16 drives the two pull plates 6 to move away from each other, and the U-shaped plate 9 moves upward. The return movement of the pull plates 6 can drive the moving plate 7 to move back, so that the four pressing blocks 3 move back synchronously. The pressing blocks 3 separate from the screening plate 2, thus loosening the screening plate 2. The operation is simple and convenient.

[0030] The positioning bolt 13 is threadedly connected to the handle 12, and a connecting groove is provided on the side of the screening frame 1. The end of the positioning bolt 13 is connected to the connecting groove. When the handle 12 is positioned, the positioning bolt 13 is rotated to move it forward, and the end of the positioning bolt 13 connects to the connecting groove, thereby limiting and fixing the handle 12. When the handle 12 needs to be loosened, the positioning bolt 13 is rotated back to move it backward, and the end of the positioning bolt 13 separates from the connecting groove, thereby loosening the handle 12.

[0031] A limiting block 11 is connected to the side of the filter box 1, and the limiting block 11 is connected to the handle 12. When the handle 12 rotates to a certain position and contacts the limiting block 11, the protruding end of the cam 14 presses against the U-shaped plate 9, and the limiting block 11 blocks the handle 12 to prevent the handle 12 from continuing to rotate.

[0032] The screening frame 1 is detachably connected to a baffle 5, and a handle 10 is connected to the side of the baffle 5. After the material screening is completed, the baffle 5 is opened to facilitate the discharge of unevenly distributed material.

[0033] Working principle: During use, when installing the screening plate 2, place the screening plate 2 into the placement slot 17. Rotating the handle 12 drives the cam 14 to rotate, so that the protruding end of the cam 14 presses against the U-shaped plate 9. The U-shaped plate 9 drives the two pull plates 6 to move closer to each other, the spring 16 is compressed, the pull plates 6 pull the moving plate 7 to move, and simultaneously drive the pressing block 3 to move, so that the pressing block 3 presses against the top of the screening plate 2, thereby locking and fixing the screening plate 2, improving the stability of the connection between the screening plate 2 and the screening frame 1, replacing the traditional method of fixing with bolts, and then rotating the positioning bolt 13 to limit the rotation of the handle 12, preventing the cam 14 from rotating and avoiding the movement of the pressing block 3. When the screening plate 2 needs to be loosened and replaced, the positioning bolt 13 is operated to loosen the handle 12. The rotating handle 12 drives the cam 14 to rotate, and the compressed spring 16 drives the two pull plates 6 to move away from each other. The U-shaped plate 9 moves upward, and the pull plates 6 push the moving plate 7 to move, so that the pressing block 3 moves back and the pressing block 3 separates from the screening plate 2, thus loosening the screening plate 2. This facilitates disassembly and is highly practical.

[0034] 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.
