Description

A cement mill anti-clogging grate structure Technical Field

[0001] This invention relates to the field of cement mill technology, and in particular to a cement mill anti-clogging grate structure. Background Technology

[0002] Cement mills are the core grinding equipment in cement production processes. Their main function is to grind raw materials such as cement clinker, slag, and gypsum into fine powder that meets production standards, providing a key raw material guarantee for the subsequent preparation of cement products. Among the internal structures of cement mills, the grate is an indispensable key component. It is usually installed in the mill's partition plate or at the discharge end. It can screen the grinding media, prevent coarse particles that do not meet the fineness requirements from continuing to participate in grinding, and guide the qualified fine powder to be smoothly discharged from the mill cavity, thereby achieving control over the grinding accuracy of materials and stable regulation of the mill's internal conditions.

[0003] However, in the actual production process of cement mills, the grate holes of traditional grate plates are prone to clogging due to factors such as raw material moisture, particle adhesion, and fine powder accumulation. This leads to obstructed material discharge and poor ventilation inside the mill, which not only significantly reduces the grinding efficiency of cement mills and increases equipment operating energy consumption, but may also cause problems such as material accumulation inside the mill, accelerated wear of grinding media, and even equipment overload shutdown, seriously restricting the continuous and stable operation of cement production lines. To address these issues, we propose an anti-clogging grate plate structure for cement mills. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art by proposing a cement mill anti-clogging grate structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cement mill anti-clogging grate structure includes a main body of the equipment. A support frame is fixedly installed on the inner wall of the main body. A grate plate evenly distributed in a ring is fixedly installed on the support frame. A sieve plate is fixedly installed on the support frame. A ring is fixedly installed on the support frame. A sliding groove is formed on the ring. A fixed plate evenly distributed in a ring is slidably installed on the sliding groove. A driving component is rotatably installed through and on each fixed plate. A scraper is rotatably installed on each driving component.

[0007] In the above-mentioned anti-clogging grate structure for a cement mill, an annular groove is provided on the ring, and the annular groove is connected to the sliding groove, and one end of the driving component is slidably mounted on the annular groove.

[0008] In the above-mentioned anti-clogging grate structure for a cement mill, push plates that are uniformly distributed in a ring are fixedly installed on the annular groove.

[0009] In the above-mentioned anti-clogging grate structure for a cement mill, a vibrating plate uniformly distributed in a ring is fixedly installed on the ring.

[0010] In the above-mentioned anti-clogging grate structure for a cement mill, an arc-shaped drive groove is provided on the ring, and a second sliding groove connected to the arc-shaped drive groove is provided on the ring.

[0011] In the above-mentioned anti-clogging grate structure for a cement mill, a fixed plate 2 is slidably installed on the sliding groove 2 in a ring-shaped and uniformly distributed manner, and an adjusting rod is fixedly installed through and fixed on each of the fixed plates 2.

[0012] In the above-mentioned anti-clogging grate structure for a cement mill, each scraper has a limiting groove, and each limiting groove has a plate body slidably installed on it, and each plate body is rotatably installed on a corresponding adjusting rod.

[0013] In the above-mentioned anti-clogging grate structure for a cement mill, each grate is fixedly installed with a dredging plate that is evenly distributed in a linear pattern.

[0014] Compared with existing technologies, the advantages of this invention are: 1. In the process of crushing and grinding cement materials, the present invention, through the cooperation of multiple push plates and driving components, enables multiple scrapers to intermittently scrape and vibrate clean the cement materials adhering to the surfaces of the corresponding two grate plates, thereby helping to improve the continuous screening speed of cement materials by the grate plate 3 and improve the stability of the continuous processing efficiency of cement materials by the equipment.

[0015] 2: In the process of crushing and grinding cement materials, the present invention can intermittently unclog the screen holes on the grate by means of the arc-shaped drive groove, the adjustment rod and multiple unblocking plates. This can help to further improve the automatic cleaning effect of the grate, improve the smoothness of the grate in continuously screening cement materials, and further improve the continuous stability of the equipment in crushing and grinding materials.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Referring to Figures 1-11, a cement mill anti-clogging grate structure includes a main body 1, a support frame 2 fixedly installed on the inner wall of the main body 1, grate plates 3 evenly distributed in a ring fixedly installed on the support frame 2, and a sieve plate 4 fixedly installed on the support frame 2.

[0020] Referring to Figures 1-8 and 11, a ring 5 is fixedly installed on the support frame 2. A groove 8 is provided on the ring 5. Fixed plates 9 are slidably installed on the groove 8 in a ring shape. A driving component 14 is rotatably installed through and on each fixed plate 9. A scraper 15 is rotatably installed on each driving component 14.

[0021] The annular groove 7 is provided on the ring 5, and the annular groove 7 is connected to the sliding groove 8. One end of the driving member 14 is slidably mounted on the annular groove 7.

[0022] Push plates 13, which are evenly distributed in a ring, are fixedly installed on the annular groove 7.

[0023] Vibrating plates 6, evenly distributed in a ring shape, are fixedly installed on the ring 5.

[0024] When the main body 1 of the equipment is running and begins to crush and grind the cement material, it can drive the support frame 2 and its multiple grate plates 3, screen plates 4, and ring 5 to rotate clockwise in the direction shown in Figure 2. At the same time, as the ring 5 rotates with the whole, it can drive multiple vibrating plates 6 and multiple push plates 13 to rotate together. During this process, the thrust applied by the vibrating plate 6 at the lower end of the ring 5 to the corresponding scraper 15, and the thrust applied by the push plate 13 at the lower end of the ring 5 to the ball at the end of the corresponding driving component 14 (as can be seen from Figure 10, the driving component 14 is composed of a ball and a rod, the ball is fixedly connected to the corresponding rod, and the ball is slidably installed in the annular groove 7, and the rod is rotatably connected to the corresponding scraper 15) can make the scraper 15 at the lower end of the ring 5 rotate clockwise with the ring 5.

[0025] When the scraper 15 located at the lower end of the ring 5 is pushed and rotated to be directly above the ring 5 (in the direction shown in Figure 2), and is still subject to clockwise rotational thrust (in the direction shown in Figure 2), and begins to rotate downward, under the combined effect of the scraper 15's own weight and the weight of its components, the drive component 14 on the scraper 15 can slide along the annular groove 7 and make clockwise acceleration motion. That is, at this time, the scraper 15 will rotate clockwise relative to the ring 5 and the corresponding two grate plates 3, gradually moving away from the corresponding vibrating plate 6 and push plate 13.

[0026] When the scraper 15 is pushed and rotated to be directly above the ring 5, and begins to rotate clockwise with acceleration relative to the ring 5 and the two corresponding grate plates 3 under its own gravity, the scraper 15 can scrape off the cement material adhering to the surface of the two corresponding grate plates 3, thereby achieving the effect of automatic cleaning of the grate plates 3. This helps to reduce the clogging of the screen holes on the grate plates 3, which can lead to problems such as obstructed material discharge and poor ventilation inside the mill. It also helps to improve the continuous screening effect and speed of the grate plates 3 on cement materials, that is, to improve the stability of the equipment's continuous cement material processing efficiency.

[0027] Furthermore, when the scraper 15 rotates clockwise relative to the ring 5 and the corresponding two grate plates 3 (in the direction shown in Figure 6), until the scraper 15 hits the vibrating plate 6 on its rotational path, the vibrating plate 6 can effectively intercept the scraper 15 through its blocking effect. During this process, the vibration generated by the scraper 15 hitting the corresponding vibrating plate 6 can be transmitted to the corresponding two grate plates 3 through the vibrating plate 6, further shaking off the cement material adhering to the corresponding two grate plates 3. This can help to further improve the self-cleaning effect of the equipment on the grate plates 3, and further improve the speed and effect of the grate plates 3 in screening cement materials during continuous use.

[0028] Meanwhile, as the ring 5 continuously rotates clockwise along the direction shown in Figure 6, multiple vibrating plates 6 and multiple push plates 13 are continuously driven by the force. Due to the interception of the displacement path of the scraper 15 which slides under its own weight by the vibrating plate 6, the scraper 15 will rotate clockwise along with the vibrating plate 6 until the scraper 15 rotates back to the lower end of the ring 5 by its own weight. Then, by the continuous clockwise rotation of multiple vibrating plates 6 and multiple push plates 13 driven by the ring 5, the vibrating plate 6 that was originally attached to the scraper 15 can be reattached to it, and the push plate 13 that was originally attached to the end ball of the corresponding drive member 14 can be reattached to it. After repeating the above operation steps, the scraper 15 can be made to rotate clockwise intermittently relative to the ring 5 and the corresponding two grate plates 3, thus intermittently achieving automatic cleaning of the corresponding two grate plates 3 (the other scrapers 15 have the same movement principle as the scraper 15 described above, and can also intermittently achieve automatic cleaning of the corresponding two grate plates 3).

[0029] Referring to Figures 2-11, an arc-shaped drive groove 10 is provided on the ring 5, and a sliding groove 11 connected to the arc-shaped drive groove 10 is provided on the ring 5.

[0030] A ring-shaped, evenly distributed fixing plate 12 is slidably installed on the slide groove 2 11, and an adjustment rod 16 is fixedly installed through and fixed on each fixing plate 2 12.

[0031] Each scraper 15 has a limiting groove (shown in the figure but not labeled, as can be seen in Figure 11), and each limiting groove has a plate 17 slidably installed on it, and each plate 17 is installed through and rotatably on the corresponding adjusting rod 16.

[0032] Each plate 17 is fixedly installed with a dredging plate 18 that is evenly distributed in a linear shape.

[0033] When the scraper 15 drives the corresponding drive component 14 and the adjusting rod 16 to rotate clockwise relative to the ring 5 and the two corresponding grate plates 3, the driving force applied to the adjusting rod 16 by the arc-shaped drive groove 10 can drive the adjusting rod 16 to move up and down reciprocally (along the direction shown in Figure 10) during the rotation, thereby clearing the screen holes on the two corresponding grate plates 3. This can further ensure the automatic cleaning effect of the equipment on the grate plates 3, improve the continuous screening effect and speed of the grate plates 3 on cement materials, and thus improve the stability of the equipment's continuous processing efficiency of cement materials.

[0034] Meanwhile, the time interval and distance for the arc-shaped drive groove 10 to drive the multiple adjusting rods 16 to move up and down are matched with the arc length and depth of the sieve holes on the grate plate 3. That is, when the scraper 15 and the corresponding adjusting rod 16 rotate clockwise relative to the ring 5 (in the direction shown in Figure 6), the arc-shaped drive groove 10 starts to drive the adjusting rods 16 and the corresponding plate 17 and multiple unblocking plates 18 to move downward (in the direction shown in Figure 11). At this time, the multiple unblocking plates 18 are all located directly above the sieve holes on the corresponding grate plate 3, which ensures that the unblocking plates 18 move downward. The movement of the scraper plate 15 improves the cleaning effect of the sieve holes on the corresponding grate plate 3. At the same time, when the arc-shaped drive groove 10 drives the adjustment rod 16 to move to the initial position, the scraper plate 15 drives the corresponding adjustment rod 16 and multiple cleaning plates 18 to move to the left side of the corresponding grate plate 3 (taking the grate plate 3 set below the ring 5 in Figure 6 as an example). This avoids the sieve hole wall of the grate plate 3 from obstructing the continuous clockwise rotation of the corresponding cleaning plates 18 and scraper plate 15, ensuring that the scraper plate 15 and the corresponding multiple cleaning plates 18 cooperate to continuously clean the surface of the grate plate 3 and its sieve holes.

[0035] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0036] In this invention, when the main body of the equipment 1 starts to crush and grind cement materials, it will drive the support frame 2, screen plate 4, grate plate 3 and ring 5 to rotate clockwise in the direction shown in Figure 2. During this process, the vibration plate 6 at the lower end of the ring 5 (in the direction shown in Figure 6) cooperates with the push plate 13 to apply a pushing force to the corresponding scraper 15, which can push the scraper 15 to rotate clockwise. When the scraper 15 is rotated and pushed to the top of the ring 5, and is still under the driving force of clockwise rotation, it begins to rotate clockwise downwards. At this time, under the combined force of the scraper 15's own weight and the weight of its upper components, the scraper 15 can rotate clockwise with acceleration relative to the ring 5 and the two corresponding grate plates 3. During this process, the scraper 15 scrapes away the cement materials adhering to the surface of the two corresponding grate plates 3, which can achieve self-cleaning of the grate plates 3, thereby helping to improve the continuous screening effect and speed of the grate plates 3 on cement materials.

[0037] When the scraper 15 moves clockwise relative to the ring 5 and the two corresponding grate plates 3, until the scraper 15 hits the vibrating plate 6 on its rotating path, the vibrating plate 6 can effectively intercept the scraper 15. During this process, the vibration generated by the scraper 15 hitting the corresponding vibrating plate 6 can be transmitted to the two corresponding grate plates 3 through the vibrating plate 6, further shaking off the cement material adhering to the two corresponding grate plates 3, and further improving the self-cleaning effect of the equipment on the grate plates 3.

[0038] Meanwhile, when the scraper 15 drives the corresponding adjusting rod 16 to move clockwise relative to the ring 5 and the two corresponding grate plates 3, the driving force applied to the adjusting rod 16 by the arc-shaped drive groove 10 can drive the adjusting rod 16 to move the corresponding plate 17 and multiple unblocking plates 18 up and down reciprocally (in the direction shown in Figure 11), further unblocking the screen holes on the two corresponding grate plates 3. This can help to further improve the automatic cleaning effect of the equipment on the grate plates 3, improve the smoothness of the grate plates 3 in continuously screening cement materials, and thus improve the stability of the equipment's continuous cement material processing efficiency.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
