[0002] There are many types of ultrafine powders, and aluminum hydroxide is one of them. Aluminum hydroxide has become one of the most widely used new flame retardants on the market due to its excellent low-temperature decomposition ability and smoke elimination ability, as well as its low price and non-toxicity. In the production process of aluminum hydroxide, a grinding device is usually used to crush the aluminum hydroxide to a certain particle size so that it can produce effective flame retardant ability.

[0003] In the Chinese patent publication number CN215087852U, a crushing and grinding device for processing ultrafine aluminum hydroxide is disclosed.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] The present invention provides Figure 1 An ultra-fine powder grinding device is shown, comprising:

[0035] A grinding assembly 1, a connection frame 11 connected to the inside of the grinding assembly 1 is installed at the bottom end thereof, and two filter plates 12 are movably installed in the connection frame 11; the structure and principle of the grinding assembly 1 are all prior art, and specific reference may be made to the comparative document (publication number CN215087852U, and the patent name is a crushing and grinding device for processing ultrafine aluminum hydroxide), which will not be repeated here;

[0036] As can be seen from the above, when in use, aluminum hydroxide raw material is added into the grinding component 1, and the grinding component 1 has conical surfaces to guide the raw material so that the raw material is concentrated in the grinding component 1, thereby grinding the raw material, and the ground raw material falls onto the filter plate 12 by its own weight, which is used to filter and grind the raw material to improve the grinding efficiency.

[0037] refer to Figure 1-Figure 5 As shown, the adjustment component 2 is used to reciprocate the filter plate 12 along the connection frame 11. The adjustment component 2 includes an adjustment frame 21 connected to one side of the filter plate 12 and a mounting cavity opened on one side of the connection frame 11. A fixing plate 22 is fixed in the mounting cavity, and the adjustment frame 21 is slidably sleeved on the fixing plate 22. Adjustment grooves 23 for moving the filter plate 12 are opened on both sides of the inner wall of the connection frame 11. A driving component 3 for reciprocating the adjustment frame 21 along the mounting cavity is provided on the connection frame 11;

[0038] The driving assembly 3 includes a driving motor 31 fixed to one side of the connecting frame 11 and a connecting column 35 fixed to one side of the adjusting frame 21. A connecting ring 32 is fixed to the output end of the driving motor 31, and a connecting assembly is arranged between the connecting ring 32 and the connecting column 35; the connecting assembly includes a fixing seat 33 fixed to one side of the connecting ring 32 and a connecting rod 34 sleeved on the outside of the connecting column 35, and the connecting rod 34 is sleeved on the outside of the fixing seat 33 relative to one side of the connecting column 35.

[0039] Through the above technical solution:

[0040] When in use, when ultra-fine particle size grinding is performed, the driving motor 31 drives the connecting ring 32 to rotate synchronously. When the connecting ring 32 rotates, the fixing seat 33 is driven to rotate, so that the connecting ring 32 and the fixing seat 33 are located on one side of the driving motor 31 to form an eccentric rotation. At this time, the fixing seat 33 rotates and drives the connecting rod 34 to rotate synchronously. Because the connecting rod 34 is located on the connecting ring 32 and rotates eccentrically, it is used to pull the adjusting frame 21 to reciprocate along the installation cavity and the fixing plate 22 while rotating the connecting rod 34, and the adjusting frame 21 drives the two ends of the filter plate 12 to move in the two adjusting grooves 23 respectively during the movement, and the filter plate 12 will realize reciprocating movement of the raw materials on its surface during the reciprocating movement, thereby enhancing the fluidity between the raw materials and the raw materials, and the raw materials are located on the filter plate 12. The problem of accumulation of the fallen raw materials due to the raw materials falling on the filter plate 12 by their own weight is solved, resulting in clogging of the eye holes of the filter plate 12, thereby accelerating the falling of the raw materials, improving the grinding efficiency of the raw materials, and increasing the practicality of the grinding device.

[0041] Furthermore, a guide groove is provided on one side of the connecting ring 32, and a guide column is installed in the guide groove, and one side of the guide column extends to the outside of the guide groove and is fixedly connected to one end of the fixing seat 33; based on this, through the setting of the guide groove, the fixing seat 33 can be accurately positioned when installed with the connecting ring 32, so as to be used to bolt the fixing seat 33 on the center of the connecting ring 32.

[0042] Furthermore, a positioning groove is provided on one side of the fixing plate 22, and a positioning block corresponding to the positioning groove is provided in the adjusting frame 21, and the positioning block is slidably connected to the positioning groove; based on this, by sliding between the positioning groove and the positioning block, it is used to stabilize the adjusting frame 21 and the fixing plate 22, thereby preventing the adjusting frame 21 from shifting when moving along the fixing plate 22, thereby enhancing the stability of the adjusting frame 21.

[0043] Embodiment 2

[0044] refer to Figure 1-Figure 4As shown, a mounting assembly 4 is provided between the filter plate 12 and the adjusting frame 21, and the mounting assembly 4 includes a mounting plate 41 fixed on one side of the filter plate 12 and a mounting groove 42 provided on a side of the adjusting frame 21 adjacent to the fixed plate 22, and the mounting plate 41 is located in the mounting groove 42, and a plug-in assembly for locking the mounting plate 41 along the mounting groove 42 is provided on the adjusting frame 21; the plug-in assembly includes a latch hole 45 provided on the mounting plate 41 and the adjusting frame 21 and a latch column 46 plugged into the latch hole 45, and the latch hole 45 is connected to the inside of the mounting groove 42; a limiting plate 43 is also fixed on one side of the mounting plate 41, and a limiting groove 44 matching the limiting plate 43 is provided on one side of the adjusting frame 21.

[0045] Through the above technical solution:

[0046] When in use, by holding the top of the latch column 46, the multiple lever surfaces of the latch column 46 are flat, that is, they have a large force-bearing area, so that the user can easily apply force when holding the multiple lever surfaces to pull out, thereby achieving the purpose of accelerating the assembly or disassembly operation speed. At this time, the mounting plate 41 and the limiting plate 43 are located in the mounting groove 42 and the limiting groove 44 and lose their fixing function, and the mounting plate 41 and the limiting plate 43 are located in the mounting groove 42 and the limiting groove 44. It is convenient to remove the filter plate 12 from the connecting frame 11 for replacement, which is convenient for the operator to replace or clean, and prevent long-term use from causing In case of reduced filtering effect, when the filter plate 12 is installed, firstly, the mounting plate 41 and the limit plate 43 are inserted into the mounting groove 42 and the limit groove 44 to position the filter plate 12 and the adjusting frame 21 to prevent the filter plate 12 from shifting during installation. At the same time, when the latch hole 45 on the mounting plate 41 coincides with the latch hole 45 on the adjusting frame 21, the latch column 46 is inserted into the two latch holes 45 to lock the mounting plate 41 and the mounting groove 42, thereby stably installing the filter plate 12 and further improving the practicability of the grinding device.

[0047] Embodiment 3

[0048] refer to Figure 1-Figure 3 as well as Figure 6 As shown, an assembly component 6 is provided on the filter plate 12, and the assembly component 6 is used to splice two filter plates 12 into a whole. The assembly component 6 includes a support groove 61 opened on the filter plate 12 and a first support plate 62 fixed on the filter plate 12. A second support plate 63 matched with the first support plate 62 is fixed in the support groove 61. A wedging opening 66 is opened on the filter plate 12, and a rivet hole 64 corresponding to the wedging opening 66 is opened on the second support plate 63 and the first support plate 62. A rivet column 65 is inserted into the filter plate 12, and the rivet column 65 is inserted into the rivet hole 64 corresponding to the wedging opening 66 through the wedging opening 66.

[0049] Through the above technical solution:

[0050] When in use, the rivet column 65 is pulled out upward with a certain force. At this time, the rivet column 65 moves along the rivet hole 64 and the wedging opening 66 in the direction of the force, so that the second support plate 63 and the first support plate 62 lose the locking effect, and one of the filter plates 12 is pulled towards the other filter plate 12. When moving, one of the filter plates 12 moves slowly along the adjustment groove 23. As the filter plate 12 moves, a distance is formed between it and the other filter plate 12, and then the first support plate 62 is separated from the second support plate 63, and the first support plate 62 moves along the support groove 61 in the direction of the force, thereby disconnecting the two filter plates 12, and the two filter plates 12 can be replaced independently, thereby reducing the difficulty of replacement for operators, reducing the cost of powder grinding, and further improving the practicality of the grinding device.

[0053] Through the above technical solution:

[0054] When in use, the filter plate 12 moves back and forth along the adjusting groove 23. At this time, during the movement of the filter plate 12 along the adjusting groove 23, the connecting plate 51 abuts against the abutting plate 52 and pushes the abutting plate 52 to move along the adjusting groove 23, so that the abutting plate 52 squeezes the telescopic column 53 and the spring 54 during the movement, and is used to compress the telescopic column 53 and the spring 54 along the adjusting groove 23, and absorb energy through the elastic deformation of the spring 54, thereby slowing down the force generated by the external thrust and dispersing it into the spring 54, which has the effect of buffering one side of the filter plate 12, thereby reducing the collision of the filter plate 12 when moving along the adjusting groove 23, enhancing the service life of the filter plate 12, and improving the functionality of the grinding device.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
