Description

Technical Field

[0001] This utility model relates to the field of clay crushing technology, specifically a clay crushing device for processing raw materials for sintered bricks. Background Technology

[0002] Sintered bricks are masonry bricks made from clay, coal gangue, or fly ash, etc., through molding and high-temperature firing. They have a history of over 3000 years in my country and, due to their low price, simple manufacturing process, and mature design and construction techniques, still account for a large proportion of wall materials. The production of sintered bricks requires first crushing the raw materials into particles of a suitable size to ensure the quality of the brick blanks and the smooth progress of subsequent sintering processes.

[0003] Chinese patent application number 201520697613.5 discloses a clay crushing device, which includes a frame, a clay crushing box, a stirring device, and a screen.

The two ends of the main shaft are movably mounted on the pair of main shaft through holes on the clay crushing box through bearing seats. A set of turntables are fixedly mounted on the shaft at equal intervals.

[0004] In existing and above-mentioned crushers, the internal screen design is mostly a grate-type structure with fixed aperture. When the raw material clay has a high moisture content (usually exceeding 8%) or contains a lot of fibrous impurities and sticky particles, these raw materials are very prone to sticking together due to the high moisture content during the crushing process, forming lumps or clumps, which then get stuck in the pores of the screen. Therefore, to address the above problems, a clay crushing device for processing sintered brick raw materials is proposed. Utility Model Content

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.

[0018] Example 1 Please see Figure 1-7 As shown, a clay crushing device for processing raw materials for sintered bricks also includes a motor 12 and a drive shaft 13. The motor 12 and the drive shaft 13 are connected by a chain drive. The drive shaft 13 is located inside a sleeve 1 and is rotatably connected through the sleeve 1. Blades are fixedly connected to the surface of the drive shaft 13 for crushing materials. A screen 8 is provided inside the sleeve 1. The screen 8 is cylindrical. A guide plate 4 is fixedly connected to the surface of the screen 8. The guide plate 4 passes through the sleeve 1 and is fixedly connected to the sleeve 1. The sleeve 1 has a discharge port 5 on its surface, and the discharge port 5 is located at the lower part of the sleeve 1; A steel brush 6 is provided between the sleeve 1 and the screen 8. The steel brush 6 reciprocates on the surface of the screen 8 through a bidirectional mechanism to clean the screen 8. During operation, the motor 12 is turned on, and the material is fed to the guide plate 4. Under the guidance of gravity and the guide plate 4, the material is accurately guided into the screen 8 inside the sleeve 1. The blade assembly of the crushing mechanism rotates at high speed under the drive of the transmission shaft 13, crushing the material inside the screen 8. The screen 8 classifies and screens the crushed material according to the preset particle size standard. The material that meets the particle size requirements is discharged from the discharge port 5 after being screened through the screen holes, while the coarse particles that do not meet the standard are retained inside the screen 8 and continue to be crushed. The synchronous unblocking device steel brush 6 of the equipment is powered by the transmission shaft 13 through a two-way mechanism. While the material is being crushed, the steel brush 6 continuously adheres to the inner surface of the screen 8 with a preset pressure and moves back and forth. Through mechanical brushing, it promptly removes the attached material particles and impurities that clog the screen holes, thereby effectively maintaining the permeability of the screen 8, ensuring the continuous and stable operation of the crushing and screening system, and improving the overall working efficiency and material processing quality of the equipment.

[0019] A fixing rod 11 is provided inside the steel brush 6. Both ends of the fixing rod 11 are rotatably connected through the steel brush 6. One end of the fixing rod 11 is fixedly installed with a rotating rod A10 by bolts. The other end of the rotating rod A10 is rotatably connected to the surface of the drive shaft 13. The end of the fixing rod 11 away from the rotating rod A10 is fixedly connected to the rotating rod B22 by bolts. The other end of the rotating rod B22 is fixedly connected to the surface of the rotating shaft 21. During operation, the fastening bolts on the equipment can be rotated. These bolts feature a standardized thread design that precisely matches the threaded hole of the fixing rod 11, enabling a detachable connection between the fixing rod 11 and the rotating rods A10 and B22. This connection structure design significantly simplifies the disassembly process of the steel brush 6, eliminating the need for complex disassembly of the main equipment structure and facilitating the replacement of the steel brush 6. The rotating rods A10 and B22, together with the fixing rod 11, form a U-shaped structure, which increases the stability of the steel brush 6 during operation and ensures effective cleaning.

[0020] The bidirectional mechanism includes a reduction gear and a bidirectional gear. The reduction gear includes gear C18, gear D19, gear F23, and gear G24. Gear D19 is fixedly connected to one end of the transmission shaft 13 and meshes with gear C18. An output shaft is fixedly connected to the surface of gear C18, and the other end of the output shaft is fixedly connected to the surface of gear F23. Gear F23 meshes with gear G24. The bidirectional gear includes gear A15, gear B17, and gear E20. An output shaft is fixedly connected to the surface of gear G24, and the other end of the output shaft is fixedly connected to the surface of gear B17. Gear B17 meshes with gear A15. The surfaces of gear A15 and gear B17 are respectively provided with transmission rod A14 and transmission rod B16. Transmission rod A14 and transmission rod B16 mesh with gear E20 in sequence. Gear E20 is fixedly connected to the rotating shaft 21. The rotating shaft 21 is rotatably connected to the concave block 9 through a bearing. The concave block 9 is fixedly connected to the surface of the screen 8. During operation, drive shaft 13 drives gear D19 to rotate, gear D19 drives gear C18 to rotate, gear C18 drives gear F23 to rotate via the surface-fixed output shaft, and gear F23 drives gear G24 to rotate. Since the number of teeth on the small gear is less than the number of teeth on the large gear, according to the gear transmission ratio formula (transmission ratio = number of teeth on driven gear / ... The rotational speed of the large gear decreases proportionally with the gear ratio, resulting in a speed reduction effect. Gear G24 drives gear B17 to rotate via a surface-fixed output shaft. Gear B17 drives gear A15 to rotate. Both gears A15 and B17 have symmetrically arranged transmission rods A14 and B16 on their surfaces. Gear A15 drives gear E20 to rotate forward via rotating rod A10, and gear B17 drives gear E20 to rotate in the opposite direction via rotating rod B22. This causes the steel brush 6 to rotate around the screen 8 and then rotate in the opposite direction when it reaches the guide plate 4. The concave block 9 is used to fix the gear set, thus realizing a cyclical operation. With the cooperation of the large and small gears, the speed of the steel brush 6 is reduced when working on the surface of the screen 8, thereby achieving more effective cleaning and reducing the wear of the steel brush 6.

[0021] The sleeve 1 is provided with a cover 2, which is rotatably connected to the sleeve 1 via a hinge; During operation, the cover door 2 can be opened and closed via hinges. This design provides a convenient operating channel for staff to carry out the replacement of the steel brush 6 components and internal maintenance of the equipment. The relevant operations can be completed without disassembling the cover door 2 as a whole, which effectively simplifies the maintenance process, shortens the equipment downtime for maintenance, and ensures the efficiency of equipment operation and maintenance.

[0022] The inner wall of the sleeve 1 is provided with a hydraulic rod 7. One end of the hydraulic rod 7 is rotatably connected to the inner wall of the sleeve 1, and the other end is rotatably connected to the cover door 2. During operation, when the cover 2 is opened, the hydraulic rod 7 extends synchronously with the opening of the cover 2, utilizing the pressure transmission characteristics of the hydraulic oil inside. After the cover 2 reaches the target opening angle, it forms a stable rigid support force through the hydraulic locking effect, keeping the cover 2 in a stable open state without the need for manual support or additional support components. This hydraulic rod 7 auxiliary support design not only provides workers with a spacious and safe maintenance operation space, avoiding safety hazards caused by accidental closure of the cover 2, but also allows workers to focus on the inspection, repair, or replacement of internal components, greatly improving the convenience and safety of maintenance operations, while reducing the labor intensity of single-person operations and further optimizing the equipment operation and maintenance process.

[0023] Example 2 Please see Figure 8As shown in the first embodiment, as another implementation of this utility model, a rotating wheel 23 is provided below the base frame 3, and the rotating wheel 23 is rotatably connected to the base frame 3 through a bearing; To enhance the equipment's adaptability to different sites and flexibility in repositioning, a set of swivel wheels 25 is installed beneath the base frame 3. These wheels can rotate freely around a fixed axis, providing steering capability. The addition of swivel wheels 25 completely transforms the traditional method of moving equipment, which relies on hoisting or prying. Workers can easily move the equipment within the production workshop without the need for large lifting equipment, simply by applying a small horizontal thrust. This allows for efficient adjustments to the equipment's connection to the raw material conveyor line, as well as relocating the equipment to a designated area for maintenance and repair. Furthermore, some swivel wheels 25 integrate braking devices. After the equipment reaches the target position, locking the wheels 25 prevents accidental slippage, ensuring stability during operation. This balances ease of movement with operational safety, further optimizing equipment layout and maintenance efficiency on the production floor.
