Description

Technical Field

[0001] This utility model relates to the field of recycling equipment technology, and in particular to a component for recycling waste materials used in cement product production. Background Technology

[0002] Foamed cement boards are environmentally friendly and have reuse value. They do not contain harmful chemicals, and recycling them can reduce construction waste accumulation, reduce land use, and avoid environmental pollution caused by waste incineration or landfill. In the recycling process, the remaining foamed cement boards are usually crushed first, and then separated into particles of different sizes using a closed vibrating screen. These particles can be used as recycled aggregates to produce low-strength concrete, roadbed materials, or thermal insulation mortar.

[0003] Existing enclosed vibrating screens have drawbacks. The difficulty in opening the cover makes it extremely inconvenient to perform maintenance and cleaning operations inside the equipment, increasing maintenance costs and time, and affecting the efficiency of waste material recycling.

[0004] To address the aforementioned issues, this utility model document proposes a waste material recycling component for cement product manufacturing. Utility Model Content

[0005] This utility model provides a waste material recycling component for cement product production, which solves the shortcomings of the existing technology, such as the inconvenience of opening the cover of the enclosed vibrating screen and the difficulty in internal maintenance and cleaning.

[0006] This utility model provides the following technical solution:

[0007] A waste material recycling component for cement product manufacturing includes:

[0008] The vibrating screen body has a detachable top cover. One side of the bottom of the top cover is hinged to the upper edge of the top of the vibrating screen body. The other side of the vibrating screen body and the top cover are reinforced by two fastening components. A crushing chamber is provided above the top cover. The crushing chamber is placed on the ground by a fixing frame welded to the outer wall. The discharge pipe at the bottom of the crushing chamber is connected to the feed pipe at the top of the top cover through the same conveying hose.

[0009] The grinding chamber is equipped with two transmission rods that are rotatably mounted on bearings. Multiple grinding discs are fixedly mounted on the transmission rods, and multiple grinding teeth are detachably mounted on the outer wall of the grinding discs.

[0010] In one possible design, the fastening assembly includes two hooks symmetrically fixedly disposed on the lower edge of the bottom of the cap, and a handle for use in conjunction with the corresponding hooks is fixedly disposed on the upper edge of the top of the vibrating screen body.

[0011] In one possible design, the outer wall of the pulverizing disc is provided with recesses in a ring array for initial engagement with the corresponding pulverizing teeth, and a mounting bolt is provided in the T-shaped hole in the center of the pulverizing tooth, the end of the mounting bolt being threadedly connected to the internal thread groove in the center of the corresponding recess.

[0012] In one possible design, one end of the transmission rod passes through the outer wall of the crushing chamber and is fixedly equipped with a corresponding transmission gear. The two transmission gears mesh with each other. A drive motor is fixedly installed on the top of the fixed frame. The output shaft of the drive motor passes through the inner wall of the crushing chamber and is fixedly connected to the other end of one of the transmission rods.

[0013] In one possible design, a cover for covering two drive gears is fixed to the outer wall of the crushing chamber by screws, and the cover is provided with multiple heat dissipation holes.

[0014] In one possible design, one end of the discharge pipe and the conveying hose, and the other end of the feed pipe and the conveying hose, are reinforced with corresponding clamps.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] During use, scraps and waste generated during the production of foamed cement boards are collected at the feed inlet of the crushing chamber via a conveyor belt or manually. After starting the drive motor, the output shaft drives one of the transmission rods to rotate. Due to the meshing of two transmission gears, the two transmission rods rotate synchronously in opposite directions. The crushing discs on the two transmission rods rotate accordingly. The crushing teeth impact and shear the scraps at high frequency, breaking them into fine particles. The crushing teeth are detachably connected to the mounting bolts through T-holes, which facilitates the replacement of worn teeth and reduces maintenance costs.

[0018] The crushed residue enters the feed pipe of the vibrating screen body through the discharge pipe and conveying hose. After the vibrating screen body is started, it screens the residue into particles of different sizes (such as coarse aggregate and fine aggregate) through vibration. The coarse aggregate is discharged into a designated collection bag through the discharge port at the front end of the vibrating screen body, and the fine aggregate is discharged into a designated collection bag through the discharge port at the bottom of the vibrating screen body. The screened aggregate is stored according to particle size and used to produce low-strength concrete, roadbed materials or thermal insulation mortar, realizing the recycling of residue.

[0019] When the inside of the vibrating screen needs to be inspected or cleaned, unfasten the buckle assembly (separate the buckle handle from the hook), and flip the top cover around the hinge side to open it. If the conveying hose affects the flipping of the top cover, loosen the clamps corresponding to the feed pipe and the conveying hose, remove the conveying hose, and then inspect or clean the inside of the vibrating screen.

[0020] This utility model has the following beneficial effects:

[0021] The recycling of leftover cement foam board material in this invention can reduce the accumulation of construction waste, reduce land resource occupation, and avoid environmental pollution caused by waste incineration or landfill, thus meeting environmental protection standards. The leftover material is crushed by the crushing disc and crushing teeth in the crushing chamber, which facilitates subsequent screening and reuse.

[0022] The top cover of the vibrating screen body in this utility model is detachable and reinforced by a snap fastener assembly, making it easy to open for internal inspection, cleaning and other operations; the crushing teeth are detachably connected to the crushing disc by mounting bolts, making it easy to replace the crushing teeth when they wear out.

Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] In one embodiment:

[0032] Please refer to Figure 1-4 A recycling assembly includes a vibrating screen body 1, a top cover 2, a crushing chamber 6, and related supporting structures.

[0033] The top of the vibrating screen body 1 is detachably mounted with a top cover 2. One side of the bottom of the top cover 2 is connected to the upper edge of the top of the vibrating screen body 1 by a hinge, so that it can be flipped open and closed. The other side is reinforced by two buckle components. The buckle components consist of two hooks 4 symmetrically fixed at the bottom edge of the top cover 2, and a handle 3 fixed at the top edge of the vibrating screen body 1 and used in conjunction with the hooks 4. When it is necessary to inspect or clean the inside of the vibrating screen body 1, simply separate the handle 3 from the hooks 4 to flip the top cover 2 around the hinge side and open it.

[0034] The vibrating screen body 1 is equipped with a vibrating motor (or eccentric block). The vibrating motor is driven by a power source, and eccentric blocks are installed at both ends of its rotor shaft. When the motor rotates, the eccentric blocks generate centrifugal force. This force changes with the motor speed to form a periodic excitation force. The excitation force is transmitted to the screen box of the screen body 1 through the motor housing, causing the entire screen box to vibrate at high frequency. The vibration trajectory of the screen box can be linear, circular, or elliptical. In this embodiment, linear vibration is preferred because it has high screening efficiency and simple structure.

[0035] The remaining material first falls at the feed end at the top of the screen box, and moves towards the discharge end under the action of gravity and vibration. The inclination angle of the screen box assists the material flow. After stratification, fine particles with a particle size smaller than the screen mesh size (such as fine aggregate) are located in the lower layer, and coarse particles with a particle size larger than the mesh size (such as coarse aggregate) are located in the upper layer. The fine particles in the lower layer pass through the screen mesh under the action of vibration and fall into the fine material collection area at the bottom of the screen box, and are finally discharged from the bottom discharge port. The coarse particles in the upper layer cannot pass through the screen and slide along the screen surface to the front discharge port under the action of vibration, and enter the coarse material collection area.

[0036] The crushing chamber 6 is located above the top cover 2 and is placed on the ground by a fixing frame 5 welded to the outer wall. The bottom of the crushing chamber 6 is equipped with a discharge pipe 16, and the top of the top cover 2 is equipped with a feed pipe 17. The discharge pipe 16 and the feed pipe 17 are connected by the same conveying hose 18. One end of the discharge pipe 16 and the conveying hose 18, and the other end of the feed pipe 17 and the conveying hose 18 are reinforced by corresponding clamps 19 to ensure a stable connection and prevent material leakage. If the conveying hose 18 affects the rotation of the top cover 2, the clamps 19 corresponding to the feed pipe 17 and the conveying hose 18 can be loosened, the conveying hose 18 can be removed, and then the operation can be carried out.

[0037] The interior of the crushing chamber 6 is the key area for crushing residual materials. Two transmission rods 7 are mounted on the chamber via bearings. Multiple crushing discs 8 are fixedly mounted on the transmission rods 7. The outer wall of the crushing discs 8 has notches 9 arranged in a ring array for initial engagement with the crushing teeth 10. The crushing teeth 10 have a T-shaped hole in the center, through which the mounting bolt 11 passes. Its end is threaded into the internal thread groove in the center of the notch 9, realizing a detachable connection between the crushing teeth 10 and the crushing discs 8. When the crushing teeth 10 are worn, the mounting bolt 11 can be easily unscrewed to replace the new crushing teeth 10, reducing maintenance costs.

[0038] The power transmission of the transmission rod 7 is achieved through the transmission gear 12. One end of the transmission rod 7 passes through the outer wall of the crushing chamber 6 and is fixedly equipped with a corresponding transmission gear 12. The two transmission gears 12 mesh with each other. The top of the fixed frame 5 is fixedly installed with a drive motor 13. The output shaft of the drive motor 13 passes through the inner wall of the crushing chamber 6 and is fixedly connected to the other end of one of the transmission rods 7. After the drive motor 13 is started, it drives one of the transmission rods 7 to rotate through the output shaft. Due to the meshing transmission of the two transmission gears 12, the two transmission rods 7 rotate synchronously in opposite directions. The crushing discs 8 on the two transmission rods 7 rotate accordingly. The crushing teeth 10 perform high-frequency impact and shearing on the remaining material, crushing it into fine particles.

[0039] In practical use, scraps and waste generated during the production of foamed cement boards are collected by conveyor belt or manually and fed into the feed inlet of crushing chamber 6. The drive motor 13 is started, which drives the transmission rod 7 to rotate, thereby crushing the scraps by the crushing disc 8 and crushing teeth 10. The crushed scraps enter the feed pipe 17 of the vibrating screen body 1 through the discharge pipe 16 and the conveying hose 18. After the vibrating screen body 1 is started, the scraps are screened into particles of different sizes by vibration. Coarse aggregates are discharged into a designated collection bag through the discharge port at the front end of the vibrating screen body 1, and fine aggregates are discharged into a designated collection bag through the discharge port at the bottom of the vibrating screen body 1. The screened aggregates are stored according to their particle size and used to produce low-strength concrete, roadbed materials or thermal insulation mortar, realizing the recycling of scraps.

[0040] This application can be used for the recycling of cement products, or for other fields applicable to this application.

[0042] A component for recycling waste materials in cement product manufacturing, which is used in the field of recycling equipment;

[0043] Please refer to Figure 3 To improve the safety of equipment use, a cover 14 for covering the two transmission gears 12 is fixed to the outer wall of the crushing chamber 6 by screws. The cover 14 is provided with multiple heat dissipation holes 15, which can prevent foreign objects from entering and affecting the normal operation of the transmission gears 12, and can also dissipate the heat generated during transmission.

[0044] However, as is well known to those skilled in the art, the working principle and wiring method of the vibrating screen body 1 and the drive motor 13 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0046] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
