Description

Technical Field

[0001] This utility model belongs to the field of raw material batching technology in cement production, and specifically relates to a raw material low-sulfur shale batching device. Background Technology

[0002] In cement production, raw material batching is a crucial step, as its uniformity and accuracy directly affect clinker quality and production line stability. Low-sulfur shale, as an important siliceous correcting raw material, is widely used. However, shale from stockpiles often contains large pieces of material, ironware, debris, and lumps formed due to rainwater moisture.

[0003] In existing technologies, shale is typically fed directly into a crusher via a plate feeder for crushing before being batched, or it is only subjected to a simple screen. This method has significant drawbacks: incompletely screened agglomerated materials will still enter subsequent processes, easily causing blockages and interrupting batching; at the same time, unscreened agglomerated materials affect the quality of cement.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a raw material low-sulfur shale batching device, which can solve the problem of clumped batching material after crushing not being thoroughly screened and entering subsequent processes, causing blockage of the discharge port and affecting cement quality.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A raw material low-sulfur shale batching device includes a main body and a screening mechanism. The main body includes a shell and a wear-resistant and anti-stick liner, which is fitted onto the inner wall of the shell. The screening mechanism includes a screen plate, a screen mesh, a dispersing component, and an anti-clogging component. The screen plate and screen mesh are installed sequentially inside the shell from top to bottom. The screen plate has multiple screen holes arranged in a concentric array. The dispersing component is used to disperse the material clumps on the screen plate and screen mesh. The anti-clogging component is used to clean the material clogging the screen plate and screen mesh.

[0008] In one or more embodiments of the present invention, a feed pipe is installed on the top wall panel of the housing, a plurality of magnetic suction plates are installed on the inner side wall of the feed pipe at equal intervals, and a discharge pipe is installed on the bottom wall panel of the housing.

[0009] In one or more embodiments of this utility model, a pair of slag discharge ports are installed on the side wall of the housing, and the installation positions of the pair of slag discharge ports correspond to the positions of the sieve plate and the sieve screen.

[0010] In one or more embodiments of the present invention, the dispersing assembly includes a rotating shaft rotatably connected to the housing and a plurality of dispersing plates fixedly connected to the side wall of the rotating shaft, and a motor is mounted on the upper end of the rotating shaft.

[0011] In one or more embodiments of this utility model, a plurality of the dispersing plates are respectively arranged in pairs above the sieve plate and the sieve mesh, and a plurality of dispersing spikes are fixedly connected to the front and rear side walls of the dispersing plates.

[0012] In one or more embodiments of the present invention, the anti-clogging component includes a pair of mounting plates respectively disposed at the bottom of the sieve plate and a grid plate disposed at the bottom of the sieve mesh.

[0013] In one or more embodiments of this utility model, a pair of mounting plates are symmetrically fixedly connected to the side wall of the rotating shaft, and each pair of mounting plates is equipped with a wear-resistant and anti-clogging brush, which is interference-fitted with the bottom side wall of the screen plate.

[0014] In one or more embodiments of this utility model, the grating plate is installed on the inner side wall of the housing, the aperture of the sieve hole on the grating plate is larger than the aperture of the sieve hole on the screen, and a plurality of wear-resistant elastic balls are placed on the grating plate.

[0015] In one or more embodiments of this utility model, a pair of rotating plates are fixedly connected symmetrically to the side wall of the rotating shaft, the pair of rotating plates are disposed on the grid plate, and the cross-section of the rotating plates is configured as a trapezoidal structure.

[0016] In one or more embodiments of this utility model, a connecting rod is fixedly connected to the lower end sidewall of the rotating shaft, and a scraper is fixedly connected to the end of the connecting rod away from the rotating shaft. A gap is provided between the scraper and the inner sidewall of the conical section of the shell.

[0017] Compared with the prior art, this utility model uses a screening processing mechanism to screen the material after it has been crushed by the crusher.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-4 As shown, a raw material low-sulfur shale batching device according to one embodiment of the present invention includes a main body 1 and a screening and processing mechanism 2. The main body 1 includes a shell 11 and a wear-resistant and anti-stick liner 12. The wear-resistant and anti-stick liner 12 is attached to the inner side wall of the shell 11. The screening and processing mechanism 2 includes a screen plate 21, a screen mesh 23, a dispersing component and an anti-clogging component. The screen plate 21 and the screen mesh 23 are installed in the shell 11 in a top-to-bottom manner. The screen plate 21 has a plurality of screen holes 22 arranged in a concentric circle array. The dispersing component is used to disperse the material agglomerated on the screen plate 21 and the screen mesh 23. The anti-clogging component is used to clean the material blocked on the screen plate 21 and the screen mesh 23.

[0030] When this raw material low-sulfur shale batching device is in use, the crushed material is conveyed into the housing 11 and subjected to secondary screening through the screen plate 21 and screen mesh 23. Due to the large diameter of the multiple screen holes 22 on the screen plate 21, larger lumps and impurities are intercepted during screening. The material after screening by the screen plate 21 is then screened through the screen mesh 23, which intercepts smaller lumps and impurities. This screening process by the screen plate 21 and screen mesh 23 effectively removes lumps and impurities, providing thoroughly screened batching to the cement production line and improving cement quality. During screening, the dispersing component breaks up any lumps to improve material utilization and increases the screening efficiency of the screen plate 21 and screen mesh 23, thus improving feeding efficiency. The anti-clogging component reduces or even eliminates clogging of the screen plate 21 and screen mesh 23, further enhancing screening efficiency.

[0031] Preferably, a wear-resistant and non-stick liner 12 is provided inside the housing 11, which effectively reduces the adhesion of materials to the inner wall of the housing.

[0032] like Figures 1-4As shown, a feed pipe 13 is installed on the top wall of the housing 11. Multiple magnetic suction plates 214 are installed at equal intervals on the inner wall of the feed pipe 13. When the feed pipe 13 conveys the crushed material into the housing 11, the material passes through the magnetic suction plates 214, which then adsorb and process any magnetic metal impurities in the material. A discharge pipe 14 is installed on the bottom wall of the housing 11, through which the processed material is discharged.

[0033] like Figure 3 and Figure 4 As shown, a pair of slag discharge ports 15 are installed on the side wall of the housing 11. The installation positions of the pair of slag discharge ports 15 correspond to the positions of the screen plate 21 and the screen mesh 23. Impurities and undispersed materials intercepted on the screen plate 21 and the screen mesh 23 are discharged through the slag discharge ports 15.

[0034] like Figures 1-5 As shown, the dispersing assembly includes a rotating shaft 24 rotatably connected inside the housing 11 and multiple dispersing plates 25 fixedly connected to the side wall of the rotating shaft 24. A motor 215 is mounted on the upper end of the rotating shaft 24. When the rotating shaft 24 is driven to rotate by the motor 215, the rotating shaft 24 can drive the dispersing plates 25 to rotate.

[0035] like Figures 3-5 As shown, multiple dispersing plates 25 are arranged in pairs above the sieve plate 21 and the sieve screen 23. Multiple dispersing spikes 26 are fixedly connected to the front and rear side walls of the dispersing plates 25. When the dispersing plates 25 rotate on the sieve plate 21 and the sieve screen 23, they can disperse the material on the sieve plate 21 and the sieve screen 23. At the same time, the dispersing plates 25 drive the rotation of the multiple dispersing spikes 26 to improve the dispersing efficiency of the material. The rotating shaft 24 disperses the material by stirring, which in turn improves the screening efficiency of the sieve plate 21 and the sieve screen 23.

[0036] like Figures 4-7 As shown, the anti-clogging component includes a pair of mounting plates 27 respectively disposed at the bottom of the sieve plate 21 and a grid plate 29 disposed at the bottom of the sieve mesh 23.

[0037] like Figure 4 and Figure 6 As shown, a pair of mounting plates 27 are symmetrically fixed to the side wall of the rotating shaft 24. Each mounting plate 27 is equipped with a wear-resistant anti-clogging brush 28, which is interference-fitted with the bottom side wall of the screen plate 21. When the rotating shaft 24 rotates, it drives the pair of mounting plates 27 to rotate, which in turn drives the wear-resistant anti-clogging brushes 28 to rotate. The interference fit between the wear-resistant anti-clogging brushes 28 and the screen plate 21 allows the brushes to push away the material clogging the screen holes 22, thereby clearing the blockage.

[0038] like Figure 5 and Figure 7 As shown, the grating plate 29 is installed on the inner wall of the housing 11. The aperture of the grating plate 29 is larger than that of the sieve mesh 23. Multiple wear-resistant elastic balls 210 are placed on the grating plate 29. This allows the grating plate 29 to support the wear-resistant elastic balls 210, while the material screened by the sieve mesh 23 is not blocked by the grating plate 29.

[0039] like Figure 5 and Figure 7 As shown, a pair of rotating plates 211 are symmetrically fixed to the side wall of the rotating shaft 24. The pair of rotating plates 211 are disposed on the grid plate 29, and the cross-section of the rotating plates 211 is a trapezoidal structure. When the rotating shaft 24 drives the rotating plates 211 to rotate, the wedge-shaped surface of the rotating plates 211 can push the wear-resistant elastic balls 210 to bounce on the grid plate 29, so that the wear-resistant elastic balls 210 can knock and clean the bottom of the screen 23 when they bounce, thereby clearing the material blocking the screen 23.

[0040] like Figure 3 and Figure 4 As shown, a connecting rod 212 is fixedly connected to the lower side wall of the rotating shaft 24. A scraper 213 is fixedly connected to the end of the connecting rod 212 away from the rotating shaft 24. A gap is provided between the scraper 213 and the inner side wall of the conical section of the housing 11. The rotation of the rotating shaft 24 drives the connecting rod 212 to rotate, which in turn drives the scraper 213 to rotate. When the scraper 213 rotates, it can scrape the material on the conical section and bottom of the housing 11, preventing the material from adhering inside the housing 11 and allowing the material to be quickly discharged through the discharge pipe 14. At the same time, a gap of 5-10 mm is provided between the scraper 213 and the inner side wall of the housing 11, so that the scraper 213 can scrape and clean the material on the inner side wall of the conical section of the 11, while avoiding hard contact between the scraper 213 and the housing 11 when rotating.

[0041] In operation, the crushed material is conveyed into the housing 11 through the feed pipe 13. As the material flows through the feed pipe 13, multiple magnetic plates 214 adsorb magnetic metal impurities. The material then enters the housing 11 and undergoes secondary screening via the screen plate 21 and screen mesh 23. Due to the large aperture of the multiple screen holes 22 on the screen plate 21, larger lumps and impurities are intercepted during screening. The material screened by the screen plate 21 is then screened by the screen mesh 23, which intercepts smaller lumps and impurities. This screening process by the screen plate 21 and screen mesh 23 effectively removes lumps and impurities, providing thoroughly screened batches to the cement production line and improving cement quality. During screening by the screen plate 21 and screen mesh 23, the rotating shaft 24 drives the dispersing plate 25. As the dispersing spikes 26 rotate, the dispersing plates 25 and 26 break up the agglomerated materials intercepted on the screen plates 21 and 23, allowing for better material utilization. Simultaneously, the dispersing plates 25 improve the screening efficiency of the screen plates 21 and 23, thus increasing feeding efficiency. Meanwhile, as the rotating shaft 24 drives the mounting plate 27 and wear-resistant anti-clogging brush 28 to rotate, the brush cleans the material clogging the screen holes 22. The rotating shaft 24 also drives the rotating plate 211 to rotate, causing the wear-resistant elastic balls 210 to bounce on the grid plate 29. These balls then clean the bottom of the screen 23 by tapping, reducing or even preventing clogging of the screen plates 21 and 23, further improving material screening efficiency.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
