Description

Technical Field

[0001] This utility model relates to the field of solid waste crushing technology, and in particular to a high-efficiency rotary crusher for crushing solid waste. Background Technology

[0002] Solid waste refers to various items and substances that have lost their original utilization value or have been discarded during production, daily life and other activities. These wastes may be in solid, semi-solid or gaseous state placed in containers, covering a variety of types from daily household garbage to industrial production waste. Solid waste is diverse and complex, and its composition and properties vary depending on its source. In the process of solid waste treatment, crushing is a common treatment method. Existing rotary crushers have relatively rigid structures and do not have pre-crushing structures. Some large wastes are difficult to enter between the crushing rollers. At the same time, crushing will also generate a lot of dust, which is not environmentally friendly. Therefore, this application is made. Utility Model Content

[0003] To overcome the technical defects of existing technologies, this utility model provides a high-efficiency rotary crusher for crushing solid waste, which features good crushing effect and strong environmental performance.

[0004] The technical solution adopted by this utility model is as follows: It includes a combined shell, comprising a coarse screen cylinder, a conical cylinder, and a discharge cylinder arranged sequentially from top to bottom. An open feeding hopper is installed at the top of the coarse screen cylinder. A coarse screen plate is fixedly installed inside the coarse screen cylinder. A pre-crushing and dust suppression integrated component is installed at the top of the coarse screen cylinder for crushing large particles of waste screened out by the coarse screen plate. A partition plate is fixedly installed inside the discharge cylinder, and a crushing component is installed at the top of the partition plate. The crushing component is located at the junction of the conical cylinder and the discharge cylinder. Material enters through the open feeding hopper. The material falls onto the coarse screen plate below for coarse screening. Larger particles will remain on the coarse screen plate. Then, the pre-crushing and dust suppression integrated component can crush these large pieces of material. The crushed waste can then enter the crushing component below for thorough crushing, effectively improving crushing efficiency. At the same time, the pre-crushing and dust suppression integrated component can be continuously connected to an external water source during use, and can spray water mist at an upward angle. The water mist absorbs the dust generated during the crushing process, and the water mist carrying the dust can be discharged outward through the side of the open feeding hopper, so that water does not accumulate in the shell and waste.

[0005] Preferably, the open feeding hopper includes a fixed frame installed on the top of the coarse screen cylinder and a feeding cylinder located at the center of the top of the fixed frame. The top of the feeding cylinder is provided with a conical expansion hopper. The material enters through the expansion hopper and then enters the shell below through the feeding cylinder for crushing. The fixed frame provides installation space for the feeding cylinder and has a large gap, allowing the water mist from the pre-crushing and dust suppression integrated component to be discharged to the outside of the shell and not to accumulate inside the shell.

[0006] Preferably, the pre-crushing and dust suppression integrated component consists of a fixed base located at the center of the top of the coarse screen plate and a conical dispersion column installed on the top of the fixed base. The conical dispersion column allows the material to disperse to both sides after entering.

[0007] Preferably, a plurality of hydraulic push rods are arranged in a uniform array around the outer side wall of the fixed base. A cross-shaped cutting blade is fixedly installed on the telescopic end of the hydraulic push rod. A crushing head is also provided at the end of the cross-shaped cutting blade. The movement of the cross-shaped cutting blade and the crushing head can be controlled by the hydraulic push rod. The crushing head contacts the material first and crushes it by point impact, which can effectively crush materials with insufficient toughness. The cross-shaped cutting blade can divide some tough materials that are difficult to break.

[0008] Preferably, the conical dispersion column has a water passage cavity, and a plurality of atomizing nozzles are evenly arrayed around the inclined surface of the conical dispersion column. A water inlet is provided at the top of the conical dispersion column. Both the atomizing nozzles and the water inlet are connected to the water passage cavity. In actual use, a water source is connected to the water inlet. By increasing the water pressure to a certain extent, the water can be atomized and sprayed out through the atomizing nozzles at an upward angle. The water mist is used to adsorb the dust generated during the crushing process, and the water mist carrying the dust can be discharged outward through the side of the open feeding hopper.

[0009] Preferably, the crushing assembly includes a drive motor fixedly mounted on the top of the partition plate and a rotating column mounted on the output shaft of the drive motor. The top of the rotating column is provided with a conical head. The drive motor drives the rotating column and the conical head to rotate, and the material is crushed by the pressure between the conical head and the inner wall of the conical cylinder.

[0010] Preferably, the top of the conical head is rotatably connected to the bottom of the coarse screen plate via a reinforcing connecting rod, and the side wall of the rotating column is provided with spikes, which can further shred the waste material and improve the crushing effect.

[0011] The beneficial effects of this utility model are as follows: This utility model uses an open feeding hopper to feed materials, a coarse screen plate to screen oversized particles, and then uses a pre-crushing and dust suppression integrated component to crush these large materials. The crushed waste can then enter the crushing component below for further crushing, effectively improving crushing efficiency. At the same time, the pre-crushing and dust suppression integrated component can be continuously connected to an external water source during use, and can spray water mist at an upward angle. The water mist absorbs the dust generated during the crushing process, and the water mist carrying the dust can be discharged outward through the side of the open feeding hopper, so that water will not accumulate in the shell and waste. While having a good crushing effect, it also has a good dust prevention capability, and the water mist used for dust prevention will not enter the equipment. It is highly practical.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 - Figure 5As shown, this embodiment provides a high-efficiency rotary crusher for crushing solid waste, including a combined shell 1. The shell 1 includes a coarse screen cylinder 101, a conical cylinder 102, and a discharge cylinder 103 arranged sequentially from top to bottom. Support legs 2 are provided on the side wall of the coarse screen cylinder 101. An open feeding hopper 3 is installed on the top of the coarse screen cylinder 101. A coarse screen plate 4 is fixedly installed inside the coarse screen cylinder 101. A pre-crushing and dust suppression integrated component 5 is installed on the top of the coarse screen cylinder 101 for crushing large particles of waste screened out by the coarse screen plate 4. A partition plate 7 is fixedly provided inside the discharge cylinder 103. A crushing component 6 is installed on the top of the partition plate 7. The crushing component 6 is located at the junction of the conical cylinder 102 and the discharge cylinder 103.

[0019] In actual use, the material enters through the open feeding hopper 3 and falls onto the coarse screen plate 4 below for coarse screening. Oversized particles will remain on the coarse screen plate 4, and then these large pieces of material can be crushed by the pre-crushing and dust suppression integrated component 5. The crushed waste can then enter the crushing component 6 below for thorough crushing, effectively improving crushing efficiency. At the same time, the pre-crushing and dust suppression integrated component 5 can be continuously connected to an external water source during use, and can spray water mist at an upward angle to absorb the dust generated during the crushing process. The water mist carrying the dust can be discharged outward through the side of the open feeding hopper 3, so that water will not accumulate in the shell 1 and the waste. Compared with the existing rotary crusher, this utility model has better crushing effect and better dust prevention capability, and the water mist used for dust prevention will not enter the equipment. It is highly practical.

[0020] The open feeding hopper 3 includes a fixed frame 303 installed on the top of the coarse screen cylinder 101 and a feeding cylinder 302 set at the center of the top of the fixed frame 303. The top of the feeding cylinder 302 is provided with a conical outer expansion hopper 301. The material enters through the outer expansion hopper 301 and enters the shell 1 below through the feeding cylinder 302 for crushing. The fixed frame 303 provides installation space for the feeding cylinder 302 and has a large gap, so that the water mist during dust suppression of the pre-crushing dust suppression integrated component 5 can be discharged to the outside of the shell 1 and will not accumulate inside the shell 1.

[0021] The pre-crushing and dust suppression integrated component 5 consists of a fixed base 501 located at the top center of the coarse screen plate 4 and a conical dispersion column 502 installed on top of the fixed base 501. The conical dispersion column 502 allows the material to disperse to both sides after entering. Several hydraulic push rods 503 are arranged in a uniform array around the outer wall of the fixed base 501. A cross-cutting blade 504 is fixedly installed on the telescopic end of the hydraulic push rod 503. A crushing head 505 is also provided at the end of the cross-cutting blade 504. The movement of the cross-cutting blade 504 and the crushing head 505 can be controlled by the hydraulic push rod 503. The crushing head 505 contacts the material first and crushes it by point impact, which can effectively crush materials with insufficient toughness, such as stones. The cross-cutting blade 504 can divide some tough and difficult-to-crush materials, such as metal plates. The cooperation of the cross-cutting blade 504 and the crushing head 505 can efficiently treat most solid waste.

[0022] The conical dispersion column 502 has a water passage cavity. Several atomizing nozzles 507 are evenly arrayed around the inclined surface of the conical dispersion column 502. A water inlet 506 is provided at the top of the conical dispersion column 502. Both the atomizing nozzles 507 and the water inlet 506 are connected to the water passage cavity. In actual use, a water source is connected to the water inlet 506. By increasing the water pressure to a certain extent, the water can be atomized and sprayed out through the atomizing nozzles 507 at an upward angle. The water mist is used to absorb the dust generated during the crushing process. The water mist carrying the dust can be discharged outward through the side of the open feeding hopper 3. The crushing effect is good and it also has a good dust prevention capability. Moreover, the water mist used for dust prevention will not enter the equipment.

[0023] The crushing assembly 6 includes a drive motor 601 fixedly mounted on the top of the partition plate 7 and a rotating column 602 mounted on the output shaft of the drive motor 601. The top of the rotating column 602 is provided with a conical head 603. The drive motor 601 drives the rotating column 602 and the conical head 603 to rotate. The material is crushed by the pressure between the conical head 603 and the inner wall of the conical cylinder 102. The top of the conical head 603 is rotatably connected to the bottom of the coarse screen plate 4 through a reinforcing connecting rod 605. The side wall of the rotating column 602 is provided with spikes 604. The spikes 604 can further shred the waste material and improve the crushing effect.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
