Description

Technical Field

[0001] This utility model relates to the field of brown fused alumina processing technology, specifically to a hammer crushing device for brown fused alumina blanks. Background Technology

[0002] Brown fused alumina, also known as corundum, is a brownish-red synthetic corundum produced by melting and reducing bauxite, carbon materials, and iron filings in an electric arc furnace. The production process of brown fused alumina abrasive is as follows: using alumina as the main raw material, adding additives, calcining to form brown fused alumina raw material blocks, and then crushing, grinding, and sieving to obtain brown fused alumina abrasive of different grades. Before crushing the brown fused alumina raw material blocks, they need to be processed into rough blanks for subsequent crushing operations, so a crushing equipment is required for processing.

[0003] In the prior art, patent publication number CN202321312260.3 discloses a crushing device for brown fused alumina raw material blocks, including a main body, a crushing chamber inside the main body, a feed hopper installed at the top of the crushing chamber, an adjustment mechanism installed inside the crushing chamber below the feed hopper, a driven crushing roller connected to the outside of the adjustment mechanism, and a first motor installed inside the crushing chamber at the same height as the adjustment mechanism.

[0004] The above-mentioned crushing device has some problems in actual use. The crushing method is to adjust the distance between the driven crushing roller and the driving crushing roller, and then carry out the crushing operation. Brown fused alumina raw material has high strength, and using only a single crushing method cannot effectively crush brown fused alumina raw material. Therefore, we propose a hanging hammer crushing device for brown fused alumina blanks. Utility Model Content

[0007] Crushing mechanism: It includes a fixed housing, a slewing bearing, a turntable, a central shaft, a crushing disc, a crushing shaft, and crushing hammers. The fixed housing is fixedly connected to the middle of the front side wall and the middle of the rear side wall of the machine housing. The two fixed housings are respectively provided with slewing bearings on their opposite inner sides. Turntables are fixedly connected to the inner ring surfaces of the two slewing bearings. A central shaft is fixedly connected between the middle of the two turntables. The outer arc surface of the central shaft is fixedly connected with evenly distributed crushing discs. A uniformly distributed crushing shaft is rotatably connected between the two turntables. The outer arc surface of the four crushing shafts is provided with evenly distributed crushing hammers. The front end of the central shaft extends to the outside of the front fixed housing, resulting in a strong crushing effect.

[0008] Furthermore, a microcontroller is installed on the outside of the housing, and the input terminal of the microcontroller is electrically connected to an external power source to control the normal operation of the motor.

[0009] Furthermore, the crushing mechanism also includes gears and gear rings. The gears are fixedly connected to the front and rear ends of the four crushing shafts, and gear rings are fixedly connected to the inner arc surfaces of the two fixed housings. The four gears on the front side mesh with the gear rings on the front side, and the four gears on the rear side mesh with the gear rings on the rear side. The gears are located inside the fixed housings at the same position, driving the crushing hammer to rotate.

[0010] Furthermore, it also includes a drive mechanism, which includes a transmission pulley, a motor, a drive pulley, and a belt pulley. The transmission pulley is fixedly connected to the front end of the central rotating shaft. The motor is located on the lower right side of the machine housing. The output shaft of the motor is equipped with a drive pulley. The drive pulley and the transmission pulley are connected by a belt pulley transmission.

[0011] Furthermore, the upper side of the housing is provided with a feed inlet, and a baffle is rotatably connected between the front and rear inner walls of the feed inlet via a rotating shaft to realize the feeding function.

[0012] Furthermore, the inner wall of the right side of the housing is provided with uniformly distributed impact plates, and the outer surface of the impact plates is provided with uniformly distributed triangular protrusions to achieve multi-directional impact on brown fused alumina raw materials.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the hammer crushing device for brown fused alumina blanks has the following advantages:

[0015] This crushing device adopts a planetary gear structure, which allows the crushing disc to perform primary crushing while simultaneously having four sets of rotating hammers that revolve around the central axis and rotate on their own axis to assist in crushing. This ensures that the brown corundum agglomerates are subjected to multiple hammer blows and counterattacks after entering the casing, resulting in a strong crushing effect.

[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 Figure 1-5 This embodiment provides a technical solution: a hammer crushing device for brown fused alumina blanks, which also includes a crushing mechanism 2. A single-chip microcomputer 8 is provided on the outside of the housing 1. The input end of the single-chip microcomputer 8 is electrically connected to an external power supply. A feed inlet 3 is provided on the upper side of the housing 1. A baffle 4 is rotatably connected between the front and rear inner walls of the feed inlet 3 through a rotating shaft. A uniformly distributed impact plate 5 is provided on the right inner wall of the housing 1. The outer surface of the impact plate 5 is provided with uniformly distributed triangular protrusions. The four corners of the lower side of the housing 1 are provided with uniformly distributed raised support feet 6. When the brown fused alumina raw material enters, the baffle 4 rotates counterclockwise by a specified angle. When the brown fused alumina raw material enters, it is affected by gravity and the baffle 4 resets to prevent brown fused alumina particles from jumping out of the feed inlet 3 during the processing.

[0024] Crushing Mechanism 2: It includes a fixed housing 21, a slewing bearing 22, a turntable 23, a central shaft 24, a crushing disc 25, a crushing shaft 26, and crushing hammers 27. The fixed housing 21 is fixedly connected to the middle of the front side wall and the middle of the rear side wall of the housing 1. The two fixed housings 21 are respectively provided with slewing bearings 22 on their opposite inner sides. The inner ring surfaces of the two slewing bearings 22 are respectively fixedly connected to the turntables 23. A central shaft 24 is fixedly connected between the middle of the two turntables 23. The outer arc surface of the central shaft 24 is fixedly connected with evenly distributed crushing discs 25. The two turntables 23 are rotatably connected with evenly distributed crushing shafts 26. The outer arc surfaces of the four crushing shafts 26 are provided with evenly distributed crushing hammers 27. The front end of the central shaft 24 extends to the front side. The crushing mechanism 2, located outside the fixed housing 21, also includes gears 28 and gear rings 29. Gears 28 are fixedly connected to the front and rear ends of four crushing shafts 26. Gear rings 29 are fixedly connected to the inner arc surfaces of the two fixed housings 21. The four front gears 28 mesh with the front gear rings 29, and the four rear gears 28 mesh with the rear gear rings 29. The gears 28 are located inside the fixed housings 21 at the same position. The mechanism also includes a drive mechanism 7, which includes a transmission pulley 71, a motor 72, a drive pulley 73, and a pulley 74. The transmission pulley 71 is fixedly connected to the front end of the central shaft 24. The motor 72 is located on the lower right side of the housing 1, and the output shaft of the motor 72 is equipped with a drive pulley 73. The driving pulley 73 and the transmission pulley 71 are connected by a pulley 74. The input end of the motor 72 is electrically connected to the output end of the microcontroller 8. When the crushing device is needed, the microcontroller 8 can be adjusted to operate the motor 72. The output shaft of the motor 72 rotates, which in turn drives the driving pulley 73 to rotate. The driving pulley 73 then rotates through the pulley 74, which in turn drives the central shaft 24 to rotate. This, in turn, drives the two turntables 23 to rotate, which in turn drives the crushing disc 25 to rotate. During the rotation of the two turntables 23, due to the meshing relationship between the gear 28 and the gear ring 29, the crushing shaft 26 also rotates synchronously, so that the crushing shaft 26 rotates on its own axis while also revolving around the central shaft 24. The crushing shaft 26 rotates in the opposite direction to the central shaft 24, and the rotational speed of the crushing shaft 26 is higher than that of the central shaft 24. Therefore, the longitudinally arranged crushing hammers 27 rotate on their own axis while also revolving around the central shaft 24. At this time, brown fused alumina raw material can be fed into the machine housing 1 through the feed inlet 3. If the volume of the brown fused alumina raw material is large, the teeth of the crushing disc 25 will continuously strike it, causing it to bounce off the impact plate 5. The rebound from the impact plate 5 will then strike the crushing disc 25 again, breaking it into smaller pieces. The crushing hammers 27 will then strike these pieces of brown fused alumina raw material. Since the crushing disc 25 rotates clockwise while the crushing hammers 27 rotate counterclockwise, they will try to strike the pieces of brown fused alumina raw material upwards.While forcing the lumpy brown fused alumina material to break down, the more solid lumps are then struck again against the impact plate 5. This process is repeated until the broken brown fused alumina material is discharged from the bottom along the casing 1. The raised support legs 6 then support the casing 1, transforming the broken brown fused alumina material into rough brown fused alumina blanks for subsequent collection.

[0025] The working principle of the hammer crushing device for brown fused alumina blanks provided by this utility model is as follows: When the crushing device is needed, the microcontroller 8 and motor 72 can be controlled to operate. The output shaft of motor 72 rotates, which in turn drives the drive pulley 73 to rotate. The drive pulley 73 then rotates through the pulley 74, which in turn drives the central shaft 24 to rotate, which in turn drives the two turntables 23 to rotate, which in turn drives the crushing disc 25 to rotate. During the rotation of the two turntables 23, due to the meshing relationship between the gear 28 and the gear ring 29, the crushing shaft 26 also rotates synchronously. This causes the crushing shaft 26 to rotate on its own axis and revolve around the central shaft 24. The direction of rotation of the crushing shaft 26 is opposite to that of the central shaft 24, and the rotation speed of the crushing shaft 26 is higher than that of the central shaft 24. Therefore, the longitudinally arranged crushing hammers 27 will rotate on their own axis and revolve around the central shaft. 24. During the revolution, brown fused alumina raw material can be fed into the machine housing 1 through the feed port 3. If the volume of the brown fused alumina raw material is large, the teeth of the crushing disc 25 will continuously strike the brown fused alumina raw material, causing it to bounce onto the impact plate 5. After being bounced back by the impact plate 5, it will bounce back onto the crushing disc 25, becoming small blocks. At this time, the crushing hammer 27 will strike the blocks of brown fused alumina raw material. The crushing disc 25 rotates clockwise, while the crushing hammer 27 rotates counterclockwise, trying to strike the blocks of brown fused alumina raw material upwards. While forcing the blocks of brown fused alumina raw material to be crushed, the more solid blocks of brown fused alumina raw material will be struck again onto the impact plate 5. The above steps are repeated. At this time, the crushed brown fused alumina raw material will be discharged from the bottom along the machine housing 1. At this time, the raised support leg 6 will support the machine housing 1. The crushed brown fused alumina raw material will become brown fused alumina blanks, which can be collected later.

[0026] It is worth noting that the microcontroller 8 core chip disclosed in the above embodiments is a microcontroller, specifically the S7-200 model. The motor 72 can be freely configured according to the actual application scenario. It is recommended that the motor 72 be a YE2 series three-phase asynchronous motor. The microcontroller 8 controls the operation of the motor 72 using methods commonly used in the prior art.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
