Description

Technical Field

[0001] This utility model relates to the field of brick-making technology, specifically to a brick-making raw material screening and impurity removal device with preliminary crushing function. Background Technology

[0002] Sintered bricks are a general term for bricks used to build walls, made from clay, fly ash, or coal gangue. In the production of sintered bricks, the raw materials need to be crushed for production. However, the raw materials may contain some large particles of impurities. The presence of large particles of impurities in the raw materials during the production process will lead to a decrease in the quality of sintered bricks.

[0003] Existing raw material removal devices cannot pulverize raw materials, resulting in larger particles that degrade the quality of sintered bricks. Larger particles also hinder subsequent impurity removal, leading to material waste. Therefore, these devices do not meet current requirements. To address this, we propose a brick-making raw material screening and impurity removal device with preliminary pulverization capabilities. Utility Model Content

It has the advantages of effectively screening raw materials, improving the efficiency of crushing and screening, thereby improving production quality, and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A brick-making raw material screening and impurity removal device with preliminary crushing includes a support box and an annular support.

[0019] Reference Figures 1 to 3 This utility model provides a technical solution: a screening and impurity removal device for brick-making raw materials with preliminary crushing, including a support box 17 and an annular support 12. A filter cylinder 8 is connected between the support box 17 and the annular support 12. A cylindrical filter screen 19 is coaxially arranged and rotatably connected to the filter cylinder 8. Both ends of the cylindrical filter screen 19 are coaxially connected to annular end plates 6. The end of one annular end plate 6 is rotatably connected to the support box 17 and the filter cylinder 8 through a bearing, and the end of the other annular end plate 6 is rotatably connected to the annular support 12 and the filter cylinder 8 through a bearing. Multiple toothed plates 11 are equidistantly connected along the circumference on the outer wall of the annular end plate 6. A second motor 9 is fastened to the outer wall of the filter cylinder 8. A gear 10 is coaxially connected to the output end of the second motor 9. The gear 10 and the toothed plates 11 are meshed together. Figure 1 , 2 As shown, the second motor 9 drives the gear 10 to rotate. Under the meshing action of the gear 10 and the toothed plate 11, the annular end plate 6 can be rotated, thereby realizing the effective screening of the raw materials located in the cylindrical filter screen 19.

[0020] like Figure 2 , 3 As shown, a feeding hopper 2 is connected to the top of the support box 17, and a rotating shaft 18 is symmetrically provided at the lower end of the feeding hopper 2 and rotatably connected thereto. A pressing roller 21 is coaxially connected to the outer wall of the rotating shaft 18. The pressing roller 21 is clearance-fitted on the side close to each other. A first motor 7 is coaxially fastened to one end of the rotating shaft 18. A pressing plate 1 is symmetrically provided above the pressing roller 21, and the pressing plate 1 is connected to the inner wall of the feeding hopper 2 through an electric push rod 5. A support plate 23 connected to the inner wall of the feeding hopper 2 is provided between the pressing plate 1 and the pressing roller 21. A connecting seat 22 is fastened to the inner wall of the feeding hopper 2. The support plate 23 is connected to the top of the connecting seat 22. Several through holes 24 are opened on the top of the support plate 23.

[0021] The raw material falls onto the top of the support plate 23. The smaller diameter raw material falls through the through hole 24, while the larger diameter raw material remains on the top of the support plate 23. The electric push rod 5 is controlled to push the two pressing plates 1 to move towards each other, which realizes the rapid crushing of large particles. The crushed raw material falls from the through hole 24 and falls between the two pressing rollers 21. The pressing rollers 21 rotate in the opposite direction, which can crush the passing raw material and realize the effective crushing and processing of large particles.

[0022] Meanwhile, in order to ensure that the pressing plate 1 slides stably, a bracket 3 is fixedly fastened on the outer wall of the feed hopper 2, and the electric push rod 5 is connected to the bracket 3. Furthermore, guide rods 4 are symmetrically connected along the electric push rod 5 on the outer wall of the pressing plate 1, and the ends of the guide rods 4 are sequentially set through the outer wall of the feed hopper 2 and the bracket 3.

[0023] In summary, this brick-making raw material screening and impurity removal device with preliminary crushing features support legs 16 connected to the bottom of both the support box 17 and the annular support 12, effectively improving the stability of the device. After being crushed by pressing at the two pressing plates 1 and crushed by rolling at the two pressing rollers 21, the material is transported from the support box 17 to the cylindrical filter screen 19. The inner wall of the support box 17 is provided with inclined surfaces 20, the ends of which extend towards the cylindrical filter screen 19, facilitating rapid transport of the raw materials and improving processing efficiency. The raw material inside the cylindrical filter screen 19 can be rotated by the meshing action of the gear 10 and the toothed plate 11, thereby effectively screening the raw material inside. A hopper 14 is connected to the bottom of the filter cylinder 8, and a discharge pipe 15 is connected to the bottom of the hopper 14. Small particles of raw material after screening are discharged through the discharge pipe 15, while large particles of raw material are transported to the annular support 12. A downwardly extending guide hopper 13 is inclinedly connected to the lower end of the annular support 12 to facilitate the discharge of large particles of raw material after screening.
