Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste treatment technology, specifically relating to a crushing device for large solid waste materials. Background Technology
[0002] If large solid wastes are not effectively crushed, they will not only occupy a lot of landfill space and cause serious waste of land resources, but also cause long-term pollution to the ecological environment due to their difficulty in degradation. Therefore, it is necessary to use crushing equipment to crush large solid wastes.
[0003] Currently, the core function of crushing equipment is to crush large waste into smaller materials through mechanical force by squeezing, shearing, and impacting them for subsequent use. However, since large solid waste often contains dust, the dust will be blown outwards by the mechanical force and airflow under the high-speed operation of the crushing equipment, and will spread in the air of the crushing operation area, causing pollution to the surrounding air. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a crushing device for large solid waste materials, which solves the problem of a large amount of dust being generated and flying outwards during the crushing of solid waste.
[0005] To achieve the above objectives, a crushing device for large solid waste materials includes a working chamber, a discharge plate inside the working chamber, two sealing plates installed at the top of the working chamber, two guide plates fixedly connected to the inner side of the sealing plates, two symmetrically positioned side blowing plates at the top of the working chamber, with the two side blowing plates located on both sides of the guide plates, a top pressure blowing plate above the side blowing plates, and a blocking blowing plate inside the working chamber, with a downward pressure blowing ring installed on the inner side of the blocking blowing plate.
[0006] Preferably, material placement boxes are fixedly connected to both sides of the working chamber, and the positions of the two material placement boxes correspond to the lower ends of both sides of the discharge plate.
[0007] Preferably, the two sealing plates are disposed between the two side blowing plates, and the sealing plates are in close contact with the side blowing plates.
[0008] Preferably, there is a spacing between the two guide vanes for the passage of waste, and the top pressure blower is located above the two guide vanes.
[0009] Preferably, a material sliding block is installed at the top of the barrier blowing plate, and the material sliding block is inclined toward the center of the working chamber.
[0010] Preferably, a dust guide plate is installed on the inner wall of the working chamber, and a dust inlet is opened at the center of the dust guide plate.
[0011] Preferably, a dust collection box is slidably disposed at the bottom of the working chamber, and the dust collection box is located below the dust guide plate.
[0012] The utility model has the following beneficial effects: By combining components such as side blowing plates and barrier blowing plates, the dust generated during solid waste crushing is suppressed and moved into the working chamber. The dust inside the working chamber continues to move with the airflow to the dust collection box for collection, thereby preventing the dust generated during crushing from escaping to the outside and causing pollution to the surrounding environment.

[0015] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0016] Example: like Figure 1 As shown in Figure 5: A crushing device for large solid waste materials includes a working chamber 1, a discharge plate 11 inside the working chamber 1, two sealing plates 2 installed at the top of the working chamber 1, two guide plates 21 fixedly connected to the inner side of the sealing plates 2, two side blowing plates 3 symmetrically positioned at the top of the working chamber 1, and the two side blowing plates 3 are respectively located on both sides of the guide plates 21, a top pressure blowing plate 31 is provided above the side blowing plates 3, a blocking blowing plate 4 is provided inside the working chamber 1, and a downward pressure blowing ring 41 is installed on the inner side of the blocking blowing plate 4.
[0017] The working chamber 1 supports and connects various components, enabling the crushing of solid waste through the cooperation of these components. During use, workers pour waste between the two sealing plates 2. The waste then sits above the guide plate 21 and, guided by the guide plate 21, reaches the position between the two crushing rollers installed inside the working chamber 1. The two crushing rollers rotate in opposite directions, applying pressure to the solid waste and working in conjunction with the toothed blocks to complete the crushing operation. During the crushing operation, a blower installed inside the working chamber 1 continuously blows air towards the side plate 3. The internal airflow is distributed, and nozzles are installed on opposite sides of the two side blowing plates 3. This allows the dust generated during crushing to be blown and pressed into the middle of the two crushing rollers by the airflow from both sides. Since the airflow from the side blowing plates 3 first contacts the guide plate 21, the airflow causes the dust to tilt and move towards the middle of the two crushing rollers. Simultaneously, the top-pressure blowing plates 31 located above the two crushing rollers output airflow downwards. There are three top-pressure blowing plates 31; the two on the sides are used to blow the dust generated when the material rolls down the guide plate 21 downwards, causing the dust to enter below the guide plate 21. The central top pressure blower 31 is located at the center of the two crushing rollers. This allows the airflow from the top pressure blower 31 to prevent dust from flying outwards, while simultaneously carrying the dust suppressed by the airflow from the two side blowers 3 at the center of the crushing rollers downwards between the rollers, causing the dust to enter the working chamber 1. Inside the working chamber 1, below the crushing rollers, is a barrier blower 4. The barrier blower 4 is tightly attached to the inner wall of the working chamber 1, and the airflow from the barrier blower 4 forms an air wall, preventing dust from escaping from the discharge port on the side wall of the working chamber 1. The solid waste crushed by the crushing rollers falls to the discharge outlet. Above the material plate 11, because the discharge plate 11 is an inverted "V" shape, the garbage fragments will slide towards the discharge port opened on the side wall of the working chamber 1 above the discharge plate 11 and slide out from the inside of the working chamber 1. At the same time, the dust entering the working chamber 1 will be blown towards the discharge plate 11 by the downward blowing ring 41. The discharge plate 11 has screen holes inside, and the mesh size of the screen holes is smaller than that of the crushed garbage. This prevents the crushed solid garbage from falling downwards, while allowing the airflow to carry the dust to the bottom of the discharge plate 11, preventing the dust from escaping to the outside, thereby achieving the purpose of preventing the dust from flying outwards.
[0018] Material collection boxes 12 are fixedly connected to both sides of the working chamber 1. The positions of the two material collection boxes 12 correspond to the lower ends of the two sides of the discharge plate 11. The material collection boxes 12 fixed on both sides of the working chamber 1 are used to collect the crushed waste fragments. The positions of the two material collection boxes 12 are located at the lower ends of the two sides of the inverted "V" shaped discharge plate 11, and the positions of the material collection boxes 12 correspond to the discharge ports opened on the side walls of the working chamber 1, so that the waste fragments guided by the discharge plate 11 will move into the material collection boxes 12 for collection.
[0019] Two sealing plates 2 are positioned between two side blowing plates 3, and the sealing plates 2 and side blowing plates 3 are tightly fitted together. There is a gap between the two guide plates 21 for the passage of waste. The top pressure blowing plate 31 is located above the two guide plates 21. The two sealing plates 2 are positioned between two side blowing plates 3, and the sealing plates 2 and side blowing plates 3 are tightly fitted together, so that the airflow output by the side blowing plates 3 will not escape through the sealing plates 2 and the inner side of the side blowing plates 3. Thus, the airflow output by the two side blowing plates 3 can suppress the dust generated during crushing to the center of the crushing roller. In addition, the airflow output by the top pressure blowing plate 31 located in the middle can blow the dust downward through the gap between the guide plates 21 and carry the dust into the working chamber 1. The two top pressure blowing plates 31 located on both sides are used to blow the dust generated when the material rolls down the guide plates 21 downward, so that the dust enters below the guide plates 21 and prevents the dust from escaping to the outside.
[0020] A sliding inclined block 42 is installed at the top of the barrier blow plate 4. The sliding inclined block 42 is inclined towards the center of the working chamber 1. The sliding inclined block 42 installed at the top of the barrier blow plate 4 is used to prevent the crushed material from falling above the pressure blow ring 41. The sliding inclined block 42 is inclined towards the center of the working chamber 1, so that the material falling above the sliding inclined block 42 will be guided by the sliding inclined block 42 to slide towards the center of the working chamber 1, and then fall onto the surface of the discharge plate 11 located below. The crushed material is discharged from the inside of the working chamber 1 through the discharge plate 11.
[0021] A dust guide plate 5 is installed on the inner wall of the working chamber 1. A dust inlet 51 is opened at the center of the dust guide plate 5. A dust collection box 52 is slidably installed at the bottom of the working chamber 1, and the dust collection box 52 is located below the dust guide plate 5. The dust guide plate 5 installed on the inner wall of the working chamber 1 is used to guide the dust that follows the airflow to the bottom of the discharge plate 11, so that the dust can follow the airflow to the corresponding position of the dust inlet 51 under the guidance of the dust guide plate 5, and then reach the bottom of the dust guide plate 5 through the dust inlet 51, so that the dust can be collected into the dust collection box 52 below the dust guide plate 5. The dust guide plate 5 will block the dust located inside the dust collection box 52 to prevent the dust from flying inside the working chamber 1.
[0022] The working principle of this utility model is as follows: During use, workers can pour garbage between the two sealing plates 2. The garbage will then be positioned above the guide plate 21 and guided by the guide plate 21 to the position between the two crushing rollers installed inside the working chamber 1. The crushing rollers will apply pressure to the solid garbage and, in conjunction with the toothed blocks, complete the crushing operation. During the crushing operation, the side blowing plate 3 will continuously output airflow, which will first contact the guide plate 21, causing the airflow to carry the dust towards the center of the two crushing rollers. Simultaneously, the top pressure blowing plate 31, located above the two crushing rollers, will output airflow downwards. Because the top pressure blowing plate 31 is located at the center of the two crushing rollers, the airflow output by the top pressure blowing plate 31, while preventing dust from flying outwards, can also carry the dust suppressed by the airflow output by the two side blowing plates 3 at the center of the crushing rollers downwards from between the crushing rollers, allowing the dust to enter... The dust enters the working chamber 1, and a baffle plate 4 is installed below the crushing roller inside the working chamber 1. The baffle plate 4 is closely attached to the inner wall of the working chamber 1. The airflow output by the baffle plate 4 will form an air wall to prevent dust from escaping from the discharge port opened on the side wall of the working chamber 1. The solid waste crushed by the crushing roller will fall above the discharge plate 11. Since the discharge plate 11 is an inverted "V" shape, the waste fragments will slide above the discharge plate 11 toward the discharge port opened on the side wall of the working chamber 1 and slide out from the inside of the working chamber 1. At the same time, the dust entering the working chamber 1 will be blown toward the discharge plate 11 by the downward blowing ring 41. The discharge plate 11 has screen holes inside, and the mesh size of the screen holes is smaller than that of the crushed waste. This prevents the crushed solid waste from falling downwards, while allowing the airflow to carry the dust to the bottom of the discharge plate 11. The dust is then guided by the dust guide plate 5 and reaches the inside of the dust collection box 52 through the dust inlet 51 for collection.
