Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ceramic product production, in particular to a sieve grinding machine for alumina ceramic product production. BACKGROUND

[0002] Alumina ceramic products are ceramic products made of alumina as the main raw material through a series of processing techniques. Due to the characteristics of high hardness, high wear resistance, high corrosion resistance and high heat resistance of alumina, alumina ceramic products have wide application in various fields.

[0003] The sieve grinding machine is a device integrating screening and grinding functions, widely used in the processing of various materials. Its working principle mainly includes the following steps: first, the material enters the sieve grinding machine through the feeding port. At this time, the material is usually a mixture composed of particles of different sizes. After entering the device, the material is first subjected to preliminary screening. This process is usually completed by one or more screens. The purpose of preliminary screening is to remove large particles and other impurities to avoid affecting the subsequent grinding process. After preliminary screening, the material enters the grinding chamber. In the grinding chamber, the material is subjected to impact and friction by grinding media (such as steel balls, ceramic balls, etc.), and gradually becomes smaller particles. The size, shape and material of the grinding media will affect the grinding effect.

[0004] The difference in particle size of the material will affect the uniformity of grinding. After the material is screened by the screen, there will still be differences in particle size, so that large particles and small particles will be mixed together during the grinding process, forming uneven material distribution, thereby affecting the grinding effect. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a sieve grinding machine for alumina ceramic product production to solve the problem of uneven material distribution caused by the difference in particle size after the material is screened by the screen, which affects the grinding effect.

[0006] To achieve the above purpose, the present application provides the following technical solution: a sieve grinding machine for alumina ceramic product production, comprising: a grinding machine main body, a feeding pipe, a screen plate and a hole adjusting mechanism, the upper part of the grinding machine main body is provided with a feeding port, the feeding pipe is connected with the feeding port of the grinding machine main body, the screen plate is fixedly arranged in the interior of the feeding pipe, a plurality of groups of holes for screening are arranged on the screen plate, the hole adjusting mechanism is arranged above the screen plate, the hole adjusting mechanism comprises a guide rod welded at one end above the screen plate, a baffle arranged at one side above the holes of the screen plate and a connecting block slidingly connected with the guide rod, the baffle is shaped as a "U" shape, and the connecting block is welded at one end of the baffle.

[0007] By adopting the above technical scheme, the size of the hole can be adjusted in a sliding manner.

[0008] Preferably, the hole adjusting mechanism further comprises a fixing block welded to the other end of the screen plate, and a bearing fixedly engaged in the fixing block.

[0009] By adopting the above technical scheme, the internal structure is fixed while being able to rotate.

[0010] Preferably, the hole adjusting mechanism further comprises a bidirectional screw rod engaged in the bearing of the fixing block.

[0011] By adopting the above technical scheme, the external structure can be moved during rotation.

[0012] Preferably, the hole adjusting mechanism further comprises a sleeve sleeved on the bidirectional screw rod, the sleeve being welded to the other end of the baffle, and a thread being formed on the inner wall of the sleeve.

[0013] By adopting the above technical scheme, the bidirectional screw rod can be rotated to move the guide rod.

[0014] Preferably, the hole adjusting mechanism further comprises through holes equidistantly formed on the baffle, and the diameter of the through holes being consistent with the diameter of the holes of the screen plate.

[0015] By adopting the above technical scheme, the baffle can be matched to adjust the size of the holes of the subsequent screen plate.

[0016] Preferably, the hole adjusting mechanism further comprises a handle fixedly engaged on the bidirectional screw rod.

[0026] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the application.

[0027] The following will be described in detail with reference to the drawings in the embodiments of the application. Figures 1-4 The embodiments of the application will be described in further detail.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 The embodiment provides a technical solution: a screen grinder for producing alumina ceramic products, comprising: a grinder main body 1, a feed pipe 2, a screen plate 3, a hole adjusting mechanism 4, and a vibration motor 5.

[0030] The upper part of the grinder body 1 is provided with a feeding port, and the material in the grinding cavity is impacted and rubbed by grinding media such as steel balls and ceramic balls, and is gradually refined into smaller particles. The above is the prior art, and the following will not be described in detail. The feeding pipe 2 is connected with the feeding port of the grinder body 1, and the feeding pipe 2 provides the conveying of the material to the inside of the grinder body 1. The screen plate 3 is fixedly arranged in the inside of the feeding pipe 2 and is fixedly connected by bolts, which can be quickly disassembled and installed subsequently. A plurality of holes for screening are arranged on the screen plate 3, which can provide the screening of the material through the holes. The hole adjusting mechanism 4 is arranged above the screen plate 3, and the hole adjusting mechanism 4 can adjust the size of the holes of the screen plate 3 to meet the subsequent circulation of materials of different sizes.

[0031] The hole adjusting mechanism 4 includes a guide rod 401 welded at one end above the screen plate 3, a baffle 402 arranged at one side above the hole of the screen plate 3, and a connecting block 407 slidably connected to the guide rod 401. The guide rod 401 can provide stable horizontal movement of the rod structure. The baffle 402 shields the hole of the screen plate 3 to adjust the size of the hole of the screen plate 3. The connecting block 407 can stably move on the guide rod 401 and synchronously move the connected baffle 402. The baffle 402 is shaped as a "U" shape and can stably realize displacement work. The connecting block 407 is welded at one end of the baffle 402 and stably fixedly connected between structures. The vibration motor 5 is fixedly arranged at the middle part of the bottom of the screen plate 3. The vibration motor 5 is provided with a set of adjustable eccentric blocks at both ends of the rotor shaft. The vibration motor 5 generates exciting force by using the centrifugal force generated by high-speed rotation of the shaft and the eccentric blocks. The exciting force of the series motor has high utilization rate, low energy consumption, low noise and long service life. The above is the prior art, and the following will not be described in detail.

[0032] After the position of the baffle 402 is adjusted on the guide rod 401, the baffle 402 partially shields the mesh hole of the screen plate 3, which changes the size of the material flowing through the screen plate 3. At this time, the material is conveyed into the inside of the feeding pipe 2, and the vibration motor 5 vibrates the screen plate 3 to make the material on the screen plate 3 flow to the inside of the grinder body 1 below through the mesh hole, thereby realizing fine grinding of the material.

[0033] Embodiment 2

[0034] Please refer to Figures 1-4 The embodiment provides a technical scheme: a screening grinder for producing alumina ceramic products, which comprises a fixed block 403, a bidirectional screw rod 404, a sleeve 405, a through hole 406 and a handle 408.

[0035] The fixed block 403 welded at the other end of the screen plate 3 can be fixed and connected between structures, and a bearing is clamped and fixed in the fixed block 403, so that the bearing clamped and fixed in the fixed block 403 can stably rotate in the fixed block 403. The sleeve 405 sleeved on the bidirectional screw rod 404 is welded at the other end of the baffle 402, the sleeve 405 is connected with the baffle 402, the baffle 402 stably moves, and a thread is formed in the inner wall of the sleeve 405. The bidirectional screw rod 404 can be screwed with the sleeve 405, so that the sleeve 405 moves while the bidirectional screw rod 404 rotates.

[0036] The through hole 406 equally formed in the baffle 402 can provide the flow of materials, and the diameter of the through hole 406 is consistent with the hole diameter of the screen plate 3, so that the materials on the screen plate 3 can flow subsequently without affecting the flow of the materials on the screen plate 3. The handle 408 clamped and fixed on the bidirectional screw rod 404 can rotate to drive the bidirectional screw rod 404 to rotate.

[0037] The handle 408 is rotated, the bidirectional screw rod 404 can stably rotate in the fixed block 403 during the rotation of the handle 408, so that the sleeve 405 is synchronously rotated, and the baffle 402 connected with the sleeve 405 stably moves on the guide rod 401 during the movement of the sleeve 405.

[0038] The implementation principle of the screening mill for producing alumina ceramic products is as follows:

[0039] First, the handle 408 is rotated, the bidirectional screw rod 404 can stably rotate in the fixed block 403 during the rotation of the handle 408, so that the sleeve 405 is synchronously rotated, and the baffle 402 connected with the sleeve 405 stably moves on the guide rod 401 during the movement of the sleeve 405.

[0040] Secondly, the baffle 402 is adjusted in position on the guide rod 401 through the connecting block 407, so that the baffle 402 partially shields the mesh holes of the screen plate 3, so that the size of the materials flowing through the screen plate 3 is changed.

[0041] Finally, the materials are conveyed into the inside of the feeding pipe 2, the screen plate 3 is vibrated by the vibration motor 5, so that the materials on the screen plate 3 flow to the inside of the grinding machine main body 1 through the mesh holes, and the fine grinding of the materials is realized.

[0042] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
