Technical Field

[0001] The utility model relates to the technical field of powder micro-crushers, in particular to a powder micro-crusher with convenient replacement of sieve plates. Background Art

[0002] Powder micro-pulverizer is a kind of equipment used to finely grind materials into extremely fine powder. Powder micro-pulverizer is widely used in many fields such as chemical industry, medicine, food, minerals, etc., and plays an important role in producing high-quality powder products.

[0003] Powder micro-crushers are often equipped with sieve plates, which are also called porous plates. They have good wear resistance, long service life, moisture resistance and good wear resistance. The crushed materials are screened through the sieve holes with specific apertures on the sieve plate. Only powder that reaches the specified particle size can be discharged through the sieve plate, thereby ensuring that the particle size of the finished powder meets the requirements.

[0004] The inventor found in his daily work that when the powder micro-crusher is in use, the sieve plate is usually installed in the inner wall of the powder micro-crusher by bolts, which means that during subsequent replacement and maintenance, the machine body casing needs to be opened, and then the bolts for installing the sieve plate need to be unscrewed and disassembled using tools, resulting in cumbersome operation during overall replacement and subsequent installation, low overall maintenance efficiency, and inconvenience in replacement operations, which in turn leads to the problem that the existing powder micro-crusher is not convenient for quick disassembly and replacement of the sieve plate.

[0021] See also Figure 1-5 The utility model provides a technical solution: a powder micro-crusher with convenient replacement of sieve plates, comprising a pulverizer shell 1 and a maintenance device 3, the inner wall of the pulverizer shell 1 is provided with a sieve plate body 2, and the maintenance device 3 is arranged on the surface of the pulverizer shell 1.

[0022] Specifically, the maintenance device 3 includes a placement frame 36, which is arranged on one side of the grinder housing 1. A plug hole 33 is provided on the surface of the grinder housing 1, and the placement frame 36 is plugged into the inner wall of the plug hole 33. The placement frame 36 is composed of a rectangular frame and a placement step provided on the inner wall of the rectangular frame. The placement frame 36 is used to place the screen plate body 2. A fixing plate 32 is fixedly connected to the surface of one side of the placement frame 36. A groove 34 is provided on the surface of one side of the grinder housing 1 close to the plug hole 33. The fixing plate 32 is plugged into the inner wall of the groove 34. Two abutment plates 31 are fixedly connected to the inner wall of the grinder housing 1. A positioning component 37 is provided on the surface of the fixing plate 32, and an ejection component 38 is provided in the placement frame 36.

[0023] In this embodiment: the sieve plate body 2 can be placed in the placement frame 36, and then the placement frame 36 and the sieve plate body 2 are inserted into the insertion hole 33 on the surface of the grinder shell 1. After insertion, the abutment plate 31 can be pressed against the sieve plate body 2 for limiting the position. When replacing, the fixing plate 32 and the placement frame 36 can be pulled out of the grinder shell 1 by controlling the positioning component 37, and then the ejection component 38 can lift up the sieve plate body 2 for easy removal and replacement.

[0024] Specifically, the upper surface of the abutment plate 31 is arranged in an inclined surface, and the two abutment plates 31 are arranged symmetrically with the pulverizer housing 1 . The upper surface of the abutment plate 31 is arranged in an inclined surface, so as to facilitate the material to slide onto the screen plate body 2 .

[0025] Specifically, the positioning component 37 includes a clamping block 371. Four movable holes are provided on the surface of the fixed plate 32. There are four clamping blocks 371. The four clamping blocks 371 are respectively slidably connected to the inner walls of the four movable holes. A clamping slot 35 is provided on the inner wall of the groove 34. The clamping block 371 is clamped with the inner wall of the clamping slot 35. The clamping block 371 can be inserted into the clamping slot 35, so that the fixed plate 32 and the placement frame 36 can be positioned, thereby improving the stability of the screen plate body 2 during installation.

[0026] Specifically, one side of each of the four clamping blocks 371 corresponding to each other is fixedly connected with a handle 372 , and there are two handles 372 .

[0027] In this embodiment, the handle 372 can be used to control the two blocks 371 to move, and the handle 372 can also be used to pull out the fixing plate 32 and the placement frame 36 to replace the sieve plate body 2.

[0028] Specifically, a positioning spring 373 is fixedly connected to one side of the block 371 corresponding to the inner wall of the movable hole on the surface of the fixing plate 32. There are four positioning springs 373. The positioning springs 373 can drive the block 371 to be restricted in the slot 35, thereby improving stability during binding.

[0029] Specifically, the ejection assembly 38 includes a lifting plate 381, and there are two lifting plates 381. Two sliding grooves are provided on the surface of the placement frame 36. The two lifting plates 381 are respectively slidably connected to the inner walls of the two sliding grooves. The ejection spring 382 is fixedly connected to the side of the lifting plate 381 corresponding to the inner wall of the sliding groove.

[0030] In this embodiment: when the placement frame 36 drives the sieve plate body 2 to be pulled out from the insertion hole 33 on the surface of the grinder housing 1, the ejection spring 382 releases the elastic force, and the lifting plate 381 can lift one side of the sieve plate body 2, making it convenient for manual removal of the sieve plate body 2 for replacement.

[0031] Working principle: By setting up the maintenance device 3, when it is necessary to disassemble and replace, the two groups of blocks 371 are moved by the handle 372, and the positioning spring 373 is stressed. When the block 371 moves to a certain position and loses the restraint on the slot 35, the fixing plate 32 and the placement frame 36 are pulled outward by the handle 372, and the placement frame 36 can drive the sieve plate body 2 to be pulled out from the insertion hole 33 on the surface of the grinder shell 1. When it is pulled out to a certain position, the abutment plate 31 and the insertion hole 33 lose the restraint on the sieve plate body 2, and the ejection spring 382 releases the elastic force, and the ejection spring 382 drives the lifting plate 381 to move, thereby ejecting one side of the sieve plate body 2 out of the placement frame 36, so that the sieve plate body 2 can be manually removed from the placement for replacement. By setting up the maintenance device 3, it is convenient to quickly disassemble and replace the sieve plate in the powder micro-pulverizer, which simplifies the maintenance work of the sieve plate. The sieve plate can be inspected, repaired or replaced with parts separately, thereby improving maintenance efficiency.
