Description

Technical Field

[0001] This utility model relates to the field of hollow brick waste recycling technology, specifically a waste recycling device for hollow brick production and processing. Background Technology

[0002] Hollow bricks are building bricks made primarily from clay, shale, and fly ash through crushing, mixing, molding, sintering, or curing. They have regularly spaced pores and are lightweight, providing thermal insulation, sound insulation, and noise reduction, making them widely used in wall construction. The purpose of recycling hollow brick scraps is to process offcuts and waste bricks generated during production and reuse them in production or to manufacture other building materials, thereby reducing raw material waste and lowering production costs.

[0003] A search revealed Chinese patent application CN202220547862.6, which discloses a waste material recycling device for hollow brick production. The device includes a feeding box and a guide cylinder. A first rotating rod is installed inside the feeding box, with several sets of crushing blades fixedly attached to it. A first motor is installed on the outer wall of the feeding box, driving the first rotating rod. Electrically controlled push rods are installed on the four inner walls of the feeding box, with push plates hinged to their movable ends. The top of the push plates is rotatably connected to the inner wall of the feeding box. The electrically controlled push rods and push plates are located below the first rotating rod. The guide cylinder is located at the lower end of the feeding box and is connected to it via a guide pipe. An outlet is located at one end of the guide cylinder. A second rotating rod is installed inside the guide cylinder, with blades spirally arranged on it. A second motor is installed at the other end of the guide cylinder, with its output shaft driving the second rotating rod.

[0004] The above-mentioned technical solutions and traditional hollow brick waste recycling equipment still have defects in use. For example, when the waste material is crushed and fed into the machine, dust is easily generated, which not only easily pollutes the surrounding environment, but also causes waste of raw materials due to the scattering of fine particles, resulting in reduced waste material recycling efficiency, and may even be easily inhaled by workers, which is harmful to their health. Utility Model Content

[0005] The purpose of this utility model is to provide a waste material recycling device for hollow brick production and processing, which effectively prevents dust overflow during the material feeding process, reduces pollution to the surrounding environment, improves the working environment, and protects the health of workers, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A waste material recycling device for hollow brick production and processing includes: The recycling bin and the collection bin are provided, with the recycling bin located directly above the collection bin, the top of the recycling bin having a feed inlet, and the bottom of the recycling bin having a discharge outlet.

The crushing mechanism includes a drive roller and a driven roller rotatably installed inside the recycling bin. Both the drive roller and the driven roller are provided with toothed discs on their outer walls, and the toothed discs on the drive roller and the driven roller are arranged alternately. A dustproof mechanism for reducing dust during material feeding is installed inside the recycling bin. The discharge port of the recycling bin extends into the opening of the collection bin. The dustproof mechanism includes a dust cover, which is installed on the top opening of the collection bin by fixing screws, and the dust cover is provided with a notch for the discharge port to enter.

[0007] Preferably, an upper guide plate is provided inside the feed inlet, which guides the excess material to the meshing point of the active roller and the driven roller toothed disc. An upper motor is installed on the outer wall of the recycling bin, which is used to drive the active roller to rotate.

The two sets of gears mesh with each other, and when the motor is working, it can drive the active roller and the driven roller to rotate to crush the residual material.

[0009] Preferably, it also includes a grinding mechanism for grinding the residue, which is disposed in the recycling bin and located directly below the crushing mechanism. The grinding mechanism includes a grinding roller and grinding teeth. The grinding roller is rotatably installed at the bottom of the inner cavity of the recycling bin, and the grinding teeth are distributed around the outer wall of the grinding roller. A lower motor is installed on the outer wall of the recycling bin, and the lower motor is used to drive the grinding roller to rotate.

[0010] Preferably, the lower end of the recycling bin is semi-circular, and the inner wall of the semi-circular lower end of the recycling bin is provided with protruding teeth. The protruding teeth and the outer wall of the grinding roller are fitted with a clearance, and the protruding teeth and the grinding teeth are staggered. When the lower motor is working, the protruding teeth and the grinding teeth work together to grind the crushed residue and then convey it from the discharge port to the collection bin.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: A waste material recycling device for hollow brick production and processing includes: The recycling bin 4 and the collection bin 1 are provided. The recycling bin 4 is located directly above the collection bin 1. The top of the recycling bin 4 is provided with an inlet 15 and the bottom of the recycling bin 4 is provided with an outlet 16. The top outer wall of the collection bin 1 is provided with a support plate 2 and a bracket 3 is provided on the support plate 2. The recycling bin 4 is fixed above the collection bin 1 by the bracket 3.

[0019] The recycling bin 4 and the collection bin 1 are vertically arranged. The top inlet 15 of the recycling bin 4 is used to feed in the hollow brick residue, and the bottom outlet 16 connects to the top opening of the collection bin 1. The collection bin 1 is fixed to the recycling bin 4 by the support plate 2 and the bracket 3, forming a stable vertical structure. After being crushed and ground, the residue from the recycling bin 4 falls into the collection bin 1 below through the outlet 16 for temporary storage. This vertical layout design utilizes gravity to achieve the natural fall of materials, reducing the additional power consumption of conveying.

[0020] Please see Figure 1-3 : The crushing mechanism for recycling hollow brick residue is located inside the recycling bin 4. The crushing mechanism includes a drive roller 6 and a driven roller 7 rotatably installed inside the recycling bin 4. Both the drive roller 6 and the driven roller 7 are provided with toothed discs on their outer walls, and the toothed discs on the drive roller 6 and the driven roller 7 are arranged alternately. Specifically, an upper guide plate 5 is installed inside the feed inlet 15. The upper guide plate 5 guides the residual material to the meshing point of the gears of the drive roller 6 and the driven roller 7. An upper motor 9 is installed on the outer wall of the recovery bin 4. The upper motor 9 is used to drive the drive roller 6 to rotate. One end of the shaft of the drive roller 6 and the driven roller 7 is located outside the recovery bin 4, and both are equipped with gears 8. The two sets of gears 8 mesh with each other. When the motor is working, it can drive the drive roller 6 and the driven roller 7 to rotate and crush the residual material.

[0021] The crushing mechanism consists of a driving roller 6, a driven roller 7, and interlocking toothed discs on their outer walls. An upper motor 9 drives the driving roller 6 to rotate. Gears 8 on the shafts of the driving roller 6 and driven roller 7 mesh, thereby causing the driven roller 7 to rotate synchronously in opposite directions. An upper guide plate 5 inside the feed inlet 15 precisely guides the fed residual material to the meshing point of the toothed discs of the driving roller 6 and driven roller 7. When the residual material enters between the two toothed discs, it is crushed by the shearing, squeezing, and impact of the toothed discs. In summary, the staggered toothed disc design of the driving roller 6 and driven roller 7 creates a highly efficient crushing zone, capable of initially crushing hollow brick residue into smaller particles. Compared to single-roller crushing, this dual-roller crushing method has stronger crushing capacity and more uniform crushing effect, providing suitable material particle size for subsequent grinding processes and improving the overall processing efficiency of the recycling unit.

[0022] Please see Figure 1-3 : A dustproof mechanism for reducing dust during material feeding is installed inside the recycling bin 4. The discharge port 16 of the recycling bin 4 extends into the opening of the collection bin 1. The dustproof mechanism includes a dust cover 18, which is installed on the top opening of the collection bin 1 by fixing screws, and the dust cover 18 is provided with a notch 19 for the discharge port 16 to extend into.

[0023] The discharge port 16 of the recycling bin 4 extends into the opening of the collection bin 1, forming a relatively enclosed space in conjunction with the dust cover 18. When the crushed residue falls from the discharge port 16 into the collection bin 1, the dust cover 18 reduces the dispersion of dust into the surrounding environment due to its blocking and sealing effect. The dust control mechanism effectively solves the problem of severe dust generation during material feeding in traditional equipment. By cooperating with the dust cover 18 and the discharge port 16, a local enclosed space is formed, preventing fine particles from being lifted by the airflow. This not only protects the surrounding environment and reduces dust pollution, but also avoids waste of raw materials, improves the efficiency of residual material recovery, and protects the health of the staff.

[0024] The dust cover 18 can be made of stainless steel mesh, which has high strength and corrosion resistance, and can resist the erosion of dust (such as cement dust, sand particles, etc.) that may be generated during the crushing of hollow brick residue, preventing the material from rusting or aging and extending the service life of the dust cover 18. At the same time, the smooth surface can reduce dust adhesion and facilitate cleaning and maintenance. The mesh size of the dust cover 18 can be designed to be 100-500 micrometers, which can effectively prevent dust without affecting the material falling. A layer of filter cotton or dustproof mesh (pore size 10-50 microns) can be added to the inside of the dust cover 18 to further enhance the dustproof effect, while maintaining ventilation and material feeding efficiency by regularly replacing the filter layer. For a preferred embodiment, please refer to Figure 3-4 The system also includes a grinding mechanism for grinding the residue, located inside the recycling bin 4, directly below the crushing mechanism. The grinding mechanism includes a grinding roller 10 and grinding teeth 11. The grinding roller 10 is rotatably mounted at the bottom of the inner cavity of the recycling bin 4, and the grinding teeth 11 are distributed around the outer wall of the grinding roller 10. A lower motor 12 is mounted on the outer wall of the recycling bin 4 to drive the grinding roller 10 to rotate. The lower end of the recycling bin 4 has a semi-circular design, and the inner wall of the semi-circular lower end of the recycling bin 4 is distributed with protruding teeth 13. The protruding teeth 13 and the outer wall of the grinding roller 10 are in clearance fit, and the protruding teeth 13 and the grinding teeth 11 are staggered. When the lower motor 12 is working, the protruding teeth 13 and the grinding teeth 11 cooperate to grind the crushed residue and then convey it from the discharge port 16 to the collection bin 1. A lower guide plate 14 is provided inside the recycling bin 4, located between the crushing mechanism and the grinding mechanism. The lower guide plate 14 is used to guide the crushed residue to the grinding roller 10.

[0025] The grinding mechanism is located directly below the crushing mechanism and consists of a grinding roller 10, grinding teeth 11, a lower motor 12, and protruding teeth 13 on the semi-circular inner wall of the lower end of the recovery bin 4. The lower motor 12 drives the grinding roller 10 to rotate. The grinding teeth 11 on the outer wall of the grinding roller 10 and the protruding teeth 13 on the semi-circular inner wall of the lower end of the recovery bin 4 are staggered and fitted with a clearance. The crushed residue is guided to the grinding roller 10 by the lower guide plate 14. During the rotation of the grinding roller 10, the shearing and grinding action between the grinding teeth 11 and the protruding teeth 13 further refines the crushed residue. The refined material is conveyed from the discharge port 16 to the collection bin 1. The grinding mechanism further refines the residual material, resulting in more uniform and finer particles and improving the recycling quality. The semi-circular design at the lower end of the recycling chamber 4, along with the staggered engagement of the protruding teeth 13 and grinding teeth 11, increases the grinding area and effect, ensuring the material is thoroughly ground. The lower guide plate 14 ensures the pulverized residual material smoothly enters the grinding mechanism, preventing material accumulation and guaranteeing the continuity and efficiency of the entire recycling process. For a preferred embodiment, please refer to Figure 1 A notch 19 is provided at the lower end of the outer wall of one side of the collection chamber 1. The notch 19 is connected to the inner cavity of the collection chamber 1. A chamber door 17 is installed at the notch 19. By opening the chamber door 17, the residual material after crushing and grinding can be uniformly recycled and processed.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
