Description

Technical Field

[0001] This utility model relates to the field of solid waste crushing and treatment technology, and in particular to a solid waste crushing device. Background Technology

[0002] Solid waste (i.e., solid waste such as slag and construction waste) refers to solid items generated during production, daily life, and other activities that have lost their original value or, although not lost their value, have been discarded or abandoned. These solid wastes all need to be crushed into specific forms and then subjected to specific processing. Therefore, we urgently need a solid waste crushing device.

[0003] Currently, the method for crushing solid waste is to use crushing rollers for crushing. This involves two rotating crushing rollers interacting to crush the solid waste. However, the solid waste is placed directly on top of the crushing rollers, and the feed inlet above the rollers is open. This operation makes it very easy for the material to splash and injure the operators during the crushing process. At the same time, a large amount of dust is generated during the crushing process, which can easily pollute the air. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a solid waste crushing device. By improving the structure of the crushing device, the device avoids material splashing during the crushing process, which could injure operators, thereby improving the safety of the solid waste crushing process. At the same time, it also avoids generating a large amount of dust during the crushing process, which pollutes the air.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A solid waste crushing device includes a crushing section and a feeding section. The crushing section is used for crushing solid waste, and the feeding section is used to guide the solid waste to be crushed to the inlet end of the crushing section. The longitudinal cross-sectional shape of the feeding section is V-shaped. The feeding section includes a first feeding pipe and a second feeding pipe. The outlet end of the first feeding pipe is connected to the inlet end of the second feeding pipe, and the outlet end of the second feeding pipe is connected to the inlet end of the crushing section. The included angle between the second feeding pipe and the crushing section is α, where 0° < α < 90°.

[0007] Therefore, by designing a V-shaped feed section with a longitudinal cross-section, compared to the existing crushing method where solid waste is placed directly above the crushing roller, this method is simpler in structure and easier to operate. The V-shaped feed section changes the path of the solid waste, ensuring that the material will not splash out during the crushing process and injure the workers, thereby improving the safety of the solid waste crushing process. At the same time, it can also avoid the generation of a large amount of dust that pollutes the air during the crushing process. In addition, the angle α between the second feed pipe and the crushing section is between 0° and 90°, which ensures that the second feed pipe is in an inclined state. The inclined second feed pipe makes it difficult for material and dust to pass through, thus further improving the safety of the solid waste crushing process and avoiding the generation of a large amount of dust that pollutes the air during the crushing process.

[0008] As a further improvement to the above technical solution, the inner wall of the second feed pipe is provided with multiple water spray holes. Thus, the water sprayed through the spray holes acts on the solid waste and floating dust, causing the floating dust to adhere to the solid waste, further preventing dust from being discharged outwards through the feed section, thereby avoiding the generation of large amounts of dust polluting the air during the crushing process.

[0009] As a further improvement to the above technical solution, it also includes: a first baffle, which is installed at the inlet end of the first feed pipe and rotatably connected to the first feed pipe; a first support rod is installed between the first baffle and the first feed pipe, and the first support rod is slidably connected to the first feed pipe; a first spring is sleeved on the outside of the first support rod, and the two ends of the first spring are respectively connected to the first baffle and the first feed pipe. Therefore, because the first spring has a certain degree of elasticity, the first baffle is always kept in a normally closed state (i.e., the inlet end of the first feed pipe is always kept in a normally closed state). Thus, the material and dust generated during the solid waste crushing process cannot be discharged through the inlet end of the first feed pipe, thereby further improving the safety of the solid waste crushing process. At the same time, it can also avoid generating a large amount of dust during the crushing process and polluting the air. When solid waste needs to be added to the crushing chamber through the first feed pipe, the first baffle can automatically open under pressure. After the solid waste is added, the first baffle automatically adjusts from the open state to the closed state under the cooperation of the reverse force of the first spring.

[0010] As a further improvement to the above technical solution: the crushing section includes a crushing box, two crushing rollers, and two first driving members. The crushing rollers are rotatably connected to the crushing box, and the two crushing rollers abut against each other. The first driving members are located outside the crushing box and connected to it. The crushing rollers penetrate the crushing box and are connected to the driving end of the first driving members. Thus, activating the first driving members drives the crushing rollers to rotate, thereby utilizing the two interacting crushing rollers to achieve the crushing of solid waste.

[0011] As a further improvement to the above technical solution: a filter screen is also provided inside the crushing chamber, and the filter screen is inclined. Thus, the inclined filter screen can filter the crushed solid waste. Solid waste that does not meet the crushing requirements is discharged through the first outlet end and crushed again until it meets the crushing requirements, then discharged through the second outlet end. Solid waste that meets the crushing requirements is discharged directly through the second outlet end.

[0012] As a further improvement to the above technical solution: Multiple second driving components are provided at the bottom of the filter screen. These second driving components are connected to the crushing chamber, and their telescopic ends are connected to the filter screen. Thus, activating the second driving components drives the filter screen to continuously move closer to or further away from the crushing roller, causing the filter screen to vibrate up and down. This allows solid waste that meets the crushing requirements to fall to the first outlet end, while solid waste that does not meet the crushing requirements is pushed to the second outlet end.

[0013] As a further improvement to the above technical solution: the crushing chamber is provided with a first outlet end relative to the filter screen, and the bottom of the crushing chamber is provided with a second outlet end.

[0014] As a further improvement to the above technical solution, it also includes a second baffle, which is installed at the first outlet end and is rotatably connected to the crushing box.

[0015] As a further improvement to the above technical solution: a second support rod is installed between the second baffle and the crushing chamber. The second support rod is slidably connected to the crushing chamber, and a second spring is sleeved on the outside of the second support rod. The two ends of the second spring are respectively connected to the second baffle and the crushing chamber. Therefore, because the first spring has a certain degree of elasticity, the second baffle remains in a normally closed state (i.e., the second outlet end remains normally closed). When too much solid waste accumulates at the second outlet end, the second baffle can automatically open under pressure. After the solid waste that does not meet the crushing requirements is completely discharged, the second baffle automatically adjusts from the open state to the closed state under the counterforce of the second spring.

[0016] As a further improvement to the above technical solution, a valve is installed on the second outlet end. This allows the valve to be opened periodically to discharge solid waste that meets the crushing requirements.

[0017] The beneficial effects of this utility model are as follows:

[0018] By employing a V-shaped feed section design, compared to existing crushing methods where solid waste is directly placed above the crushing rollers, this method offers a simpler structure and easier operation. The V-shaped feed section alters the path of the solid waste, ensuring that material does not splash out during crushing and injure workers, thus improving the safety of the solid waste crushing process. It also avoids generating large amounts of dust that pollute the air during crushing. Furthermore, the angle α between the second feed pipe and the crushing section is between 0° and 90°, ensuring that the second feed pipe is tilted. This tilted position makes it difficult for material and dust to pass through, further enhancing the safety of the solid waste crushing process and preventing excessive dust pollution.

[0019] This utility model also has the following advantages:

[0020] 1. This utility model uses water sprayed from the spray nozzle to act on solid waste and floating dust, so that the floating dust adheres to the solid waste, further preventing the dust from being discharged out through the feeding part, thereby avoiding the generation of a large amount of dust that pollutes the air during the crushing process.

[0021] 2. Because the first spring of this utility model has a certain degree of elasticity, the first baffle is always kept in a normally closed state (that is, the inlet end of the first feed pipe is always kept in a normally closed state). In this way, the material and dust generated during the solid waste crushing process cannot be discharged through the inlet end of the first feed pipe, thereby further improving the safety of the solid waste crushing process. At the same time, it can also avoid the generation of a large amount of dust during the crushing process and polluting the air. When solid waste needs to be added into the crushing box through the first feed pipe, the first baffle can automatically open under pressure. After the solid waste is added, the first baffle automatically adjusts from the open state to the closed state under the cooperation of the reverse force of the first spring.

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0040] like Figures 1 to 7The diagram shows the preferred embodiment of this utility model. The solid waste crushing device of this embodiment includes: a crushing section 1 and a feeding section 2. The crushing section 1 is used for crushing solid waste, and the feeding section 2 is used to guide the solid waste to be crushed to the inlet end of the crushing section 1. The longitudinal cross-sectional shape of the feeding section 2 is V-shaped. The feeding section 2 includes: a first feeding pipe 201 and a second feeding pipe 202. The outlet end of the first feeding pipe 201 is connected to the inlet end of the second feeding pipe 202, and the outlet end of the second feeding pipe 202 is connected to the inlet end of the crushing section 1. The included angle between the second feeding pipe 202 and the crushing section 1 is α, where 0° < α < 90°. Therefore, by using a V-shaped feed section 2 with a longitudinal cross-section, compared to the existing crushing method where solid waste is directly placed above the crushing roller 102, this method has a simpler structure and is easier to operate. The V-shaped feed section 2 changes the path of the solid waste, ensuring that the material will not splash out during the crushing process and injure the workers, thereby improving the safety of the solid waste crushing process. At the same time, it can also avoid the generation of a large amount of dust that pollutes the air during the crushing process. In addition, the angle α between the second feed pipe 202 and the crushing section 1 is between 0° and 90°, which ensures that the second feed pipe 202 is in an inclined state. The inclined second feed pipe 202 makes it difficult for material and dust to pass through, thus further improving the safety of the solid waste crushing process and avoiding the generation of a large amount of dust that pollutes the air during the crushing process.

[0041] In other words, the feed section 2, with its V-shaped longitudinal cross-section, allows the solid waste to be crushed to enter the crushing chamber 101 in a zigzag pattern for crushing. The material and dust generated during the crushing process must also be discharged through the inlet end of the first feed pipe 201 in a zigzag pattern. This method makes it difficult for the material and dust generated during the crushing process to be discharged. This ensures that the material will not splash out and injure the workers during the crushing process, thereby improving the safety of the solid waste crushing process. At the same time, it can also avoid the generation of a large amount of dust during the crushing process that pollutes the air.

[0042] In this embodiment, it further includes: a first baffle 4, which is installed at the inlet end of the first feed pipe 201 and is rotatably connected to the first feed pipe 201. A first support rod 401 is installed between the first baffle 4 and the first feed pipe 201. The first support rod 401 is slidably connected to the first feed pipe 201. A first spring 402 is sleeved on the outside of the first support rod 401. The two ends of the first spring 402 are respectively connected to the first baffle 4 and the first feed pipe 201. Therefore, because the first spring 402 has a certain degree of elasticity, the first baffle 4 is always kept in a normally closed state (that is, the inlet end of the first feed pipe 201 is always kept in a normally closed state). In this way, the material and dust generated during the solid waste crushing process cannot be discharged through the inlet end of the first feed pipe 201, thereby further improving the safety of the solid waste crushing process. At the same time, it can also avoid generating a large amount of dust to pollute the air during the crushing process. When solid waste needs to be added into the crushing box 101 through the first feed pipe 201, the first baffle 4 can automatically open under pressure. After the solid waste is added, the first baffle 4 automatically adjusts from the open state to the closed state under the cooperation of the reverse force of the first spring 402.

[0043] In this embodiment, the crushing section 1 includes: a crushing box 101, two crushing rollers 102, and two first driving members 103. The crushing rollers 102 are rotatably connected to the crushing box 101, and the two crushing rollers 102 abut against each other. The first driving members 103 are located outside the crushing box 101 and connected to the crushing box 101. The crushing rollers 102 penetrate the crushing box 101 and are connected to the driving end of the first driving member 103. A filter screen 104 is also provided inside the crushing box 101. The filter screen 104 is inclined. A plurality of second driving members 105 are provided at the bottom of the filter screen 104. The second driving members 105 are connected to the crushing box 101, and the telescopic ends of the second driving members 105 are connected to the filter screen 104. A first outlet end 106 is provided in the crushing box 101 relative to the filter screen 104, and a second outlet end 107 is provided at the bottom of the crushing box 101. A valve 6 is installed on the second outlet end 107. Therefore, the first drive unit 103 is activated, which drives the crushing roller 102 to rotate, so that the two interacting crushing rollers 102 can be used to crush the solid waste. The crushed solid waste can be filtered by the inclined filter screen 104. The solid waste that does not meet the crushing requirements is discharged through the first outlet end 106 and crushed again until it meets the crushing requirements. Then it is discharged through the second outlet end 107. The solid waste that meets the crushing requirements is discharged directly through the second outlet end 107. The second drive unit 105 is activated, which drives the filter screen 104 to move continuously closer to or further away from the crushing roller 102, so that the filter screen 104 shakes up and down. In this way, the solid waste that meets the crushing requirements falls to the first outlet end 106, and the solid waste that does not meet the crushing requirements is pushed to the second outlet end 107. The valve 6 is opened to periodically discharge the solid waste that meets the crushing requirements.

[0044] For example, the first driving component 103 is an electric motor, and the second driving component 105 is a cylinder.

[0045] In this embodiment, a second baffle 5 is also included. The second baffle 5 is installed at the position of the first outlet end 106 and is rotatably connected to the crushing box 101. A second support rod 501 is installed between the second baffle 5 and the crushing box 101. The second support rod 501 is slidably connected to the crushing box 101. A second spring 502 is sleeved on the outside of the second support rod 501. The two ends of the second spring 502 are respectively connected to the second baffle 5 and the crushing box 101. Thus, because the first spring 402 has a certain degree of elasticity, the second baffle 5 is always kept in a normally closed state (i.e., the second outlet end 107 is always kept in a normally closed state). When too much solid waste accumulates at the second outlet end 107, the second baffle 5 can automatically open under pressure. After the solid waste that does not meet the crushing requirements is completely discharged, the second baffle 5 automatically adjusts from the open state to the closed state under the cooperation of the reverse force of the second spring 502.

[0046] The solid waste crushing process of this utility model is as follows: First, the solid waste to be crushed is placed into the crushing box 101 through the feeding part 2; finally, the first driving component 103 and the second driving component 105 are started, and water is sprayed into the second feeding pipe 202 through the water spray hole 3. The first driving component 103 drives the crushing roller 102 to rotate. The two mutually rotating crushing rollers 102 are used to crush the solid waste. The second driving component 105 drives the filter screen 104 to move continuously towards or away from the crushing roller 102 to filter the crushed solid waste. The solid waste that meets the crushing requirements after filtration is discharged through the first outlet end 106 (valve 6 is opened), and the solid waste that does not meet the crushing requirements is discharged through the second outlet end 107. The crushing process is repeated until the crushing requirements are met.

[0047] In summary, this utility model, through the design of a V-shaped feed section 2 with a longitudinal cross-section, offers a simpler and easier-to-operate structure compared to the existing crushing method where solid waste is directly placed above the crushing roller 102. The V-shaped feed section 2 alters the path of the solid waste, ensuring that material does not splash out and injure workers during crushing, thus improving the safety of the solid waste crushing process. It also prevents the generation of large amounts of dust that pollute the air during crushing. Furthermore, the angle α between the second feed pipe 202 and the crushing section 1 is between 0° and 90°, ensuring that the second feed pipe 202 is in an inclined state. This inclined state makes it difficult for material and dust to pass through, further enhancing the safety of the solid waste crushing process and preventing the generation of large amounts of dust that pollute the air during crushing.
