Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection, and in particular relates to a crushing device for solid waste treatment. Background Art

[0002] Solid waste refers to solid, semi-solid, and gaseous items and substances in containers that are generated in the process of production, life and other activities and have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned, as well as items and substances that are included in waste management according to laws and administrative regulations.

[0003] The double-roll shredder is a common crushing device for processing solid waste. When the material enters the crushing chamber of the double-roll shredder, the material is subjected to the meshing force of the rotating rollers, so that the material is forced to pass between the two rollers. At the same time, it is squeezed and sheared by the rollers, and the material begins to break. The broken small particles are thrown to the bottom of the machine through the gap between the two rollers along the tangent of the roller rotation. The large particles exceeding the gap continue to be broken into small particles and discharged. However, the existing double-roll shredder still has certain limitations when used. That is, when using the double-roll shredder to crush some larger solid wastes, since the size of the waste exceeds the distance between the axes of the rotating rollers, it is difficult for the waste to enter between the two rollers, making it difficult to quickly crush these wastes.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] To facilitate understanding of the scheme and effects of the embodiment of the utility model, a specific application example is given below. Those skilled in the art should understand that this example is only for facilitating understanding of the utility model, and any specific details thereof are not intended to limit the utility model in any way.

[0021] Example: Figure 1-4 As shown, the utility model is a crushing device for solid waste treatment, comprising a base 1, a chassis 2 is arranged on the top of the base 1, a feed port 3 is arranged on the top of the chassis 2, a through crushing chamber 4 is arranged at the bottom of the feed port 3, two first rotating shafts 5 are symmetrically arranged inside the crushing chamber 4, crushing rollers 6 are installed on the surface of the first rotating shafts 5, movable grooves 7 are opened on both sides of the crushing chamber 4 above the crushing rollers 6, crushing hammers 8 are installed inside the movable grooves 7, crushing cones 9 are arranged on the opposite sides of the two crushing hammers 8, and a top of the side away from the two crushing hammers 8 is arranged A rack 10 is arranged, and the end of the rack 10 away from the breaker 8 passes through the inner wall of the movable groove 7, so that the rack 10 has enough space to move. A mounting groove 11 is opened on the top of the movable groove 7, and a second rotating shaft 12 is installed inside the mounting groove 11. A special-shaped gear 13 is installed on the surface of the second rotating shaft 12, and the special-shaped gear 13 is meshed and connected with the adjacent rack 10. The special-shaped gear 13 is an incomplete gear, and only a local part of its surface has teeth. The special-shaped gear 13 is linked with the rack 10 through the toothed part to realize intermittent transmission of the rack 10.

[0022] Among them, two guide rods 14 are symmetrically arranged on both sides of the rack 10 on the side where the two breakers 8 are far away from each other. The ends of the two guide rods 14 away from the breakers 8 pass through the surface of the chassis 2, and the ends that pass through are provided with limit blocks 15. The limit blocks 15 are used to limit the travel of the breakers 8 that can enter the crushing chamber 4, so as to prevent the collision between the two breakers 8 and cause a decrease in service life.

[0023] Among them, the surface of the guide rod 14 located in the movable groove 7 is equipped with a spring 16, and the two ends of the spring 16 are respectively against the breaker 8 and the inner wall of the movable groove 7. The rebound force generated by the deformation of the spring 16 gives the breaker 8 the force to crush the solid waste.

[0024] Among them, the two first rotating shafts 5 are connected to each other through a gear set 17, and the second rotating shaft 12 is connected to the adjacent first rotating shaft 5 through a belt 18. The first rotating shaft 5 drives the second rotating shaft 12 to rotate through the belt 18, so that the two first rotating shafts 5 will maintain synchronous and opposite rotation directions, thereby driving the two crushing rollers 6 to rotate towards each other to crush the solid waste.

[0025] A screen 19 is installed inside the crushing chamber 4 near the bottom of the crushing roller 6. The crushed materials are screened through the screen 19, and solid waste that does not meet the requirements is left in the crushing chamber for further crushing.

[0026] A motor 20 is fixedly mounted on one side of the top of the base 1 , and an output end of the motor 20 is transmission-connected to one of the first rotating shafts 5 , so that the first rotating shaft 5 is driven to rotate by the motor 20 .

[0027] A support frame 21 is provided at the bottom of the base 1, and a discharge hopper 22 is installed at the bottom of the base 1 below the crushing chamber 4. The discharge hopper 22 is inclined, and the crushed solid waste falls on the discharge hopper 22 and slides downward.

[0028] Working principle: When the utility model is in use, first the utility model is connected to an external power supply and a control panel. When the utility model is used to crush solid waste, the motor 20 in the utility model is first started through the external control panel, and then the waste to be crushed is added into the chassis 2 from the feed port 3. After the waste enters the chassis 2, it will fall onto the crushing roller 6 in the crushing chamber 4, and will be crushed to a size smaller than the aperture of the screen 19 by the two crushing rollers 6 rotating in opposite directions under the action of the motor 20 and the gear set 17, and then fall into the discharge hopper for discharge. In the process again, the first rotating shaft 5 will drive the second rotating shaft 12 to rotate through the belt 18, and the second rotating shaft 12 will drive the special-shaped gear 13 to rotate. The special-shaped gear 13 is an incomplete gear, and its rotation During the process, it will only mesh with the rack 10 for a period of time. During the time when the special-shaped gear 13 is meshing with the rack 10, the rotation of the special-shaped gear 13 will pull the breaker 8 into the movable groove 7. During this process, the breaker 8 is close to the inner wall of the inner side of the movable groove 7, causing the spring 16 mounted on the guide rod 14 to shrink. When the special-shaped gear 13 is out of meshing with the rack 10, the obstruction of the special-shaped gear 13 is lost, and the elastic force of the spring 16 is released instantly, so that the breaker 8 moves quickly into the crushing chamber 4. The fast-moving breaker 8 hits the larger solid waste stuck on the crushing roller 6, thereby crushing it into a size that the crushing roller 6 can quickly handle, thereby improving the crushing efficiency of the utility model for solid waste with larger gears.

[0029] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
