Description

Technical Field

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

[0002] According to the different sources of solid waste, solid waste can be divided into domestic waste and industrial and mining solid waste. Among these solid wastes, the largest amount is mining solid waste generated in the mining and dressing process and departmental solid waste generated in the industrial production process. The composition is complex and diverse, and it is polluting, resource-related and social. The main methods for treating solid waste are sanitary landfill, high-temperature composting and incineration. In order to improve the efficiency of incineration, large volumes of solid waste must first be crushed with a crushing device.

[0003] At present, in the use of automatic circulating crushing devices for solid waste treatment, large volumes of solid waste are prone to contain large pieces of metal impurities. After crushing, the solid waste and the metal impurities need to be separated. Now, workers usually separate them by picking, which is very time-consuming and labor-intensive. In addition, dust is generated when the solid waste is crushed. The random discharge of dust will cause air pollution, and dust treatment is required. Therefore, a solid waste treatment sorting and crushing device is needed.

[0004] In the prior art, a Chinese patent with publication number CN 217646481U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a solid waste crushing and sorting device, including a crushing box, a support plate is fixedly connected to the back of the crushing box, a first motor is fixedly installed on the upper surface of the support plate, an output end of the first motor is fixedly connected to a rotating shaft, a belt is sleeved on the outer surface of the rotating shaft, a movable rod is movably connected to the inner wall of the crushing box, a crushing tooth is fixedly connected to the outer surface of the movable rod, a gear is fixedly connected to the outer surface of the movable rod, an end of the belt away from the rotating shaft is transmission-connected to the movable rod, and a partition is fixedly connected to the inner wall of the crushing box. In this solid waste treatment and sorting crushing device, when the staff crushes the waste, they start the water pump to spray the water in the water tank through the water inlet pipe, the water outlet pipe and the water outlet in the form of mist, and dust is reduced on the dust generated inside, thereby playing a role in dust reduction. However, the space occupied by the device is too large and the energy required for work is too much, which will cause the device to have a reduced working efficiency in some places with narrow space. Summary of the invention

[0005] The purpose of the utility model is to provide a solid waste crushing and sorting device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A solid waste crushing and sorting device comprises a shell, one end of the shell is fixedly connected to a motor, the output end of the motor is fixedly connected to a pulley, a rotating shaft is rotatably connected inside the shell, one end of the rotating shaft is fixedly connected to a pulley, the pulleys are connected by a belt drive, guide plates are symmetrically arranged inside the shell, the guide plates are fixedly connected to the shell, a dust removal component for dust removal is connected below the guide plates, a crushing component for crushing solid waste is connected inside the shell, a filter screen is fixedly connected to the bottom of the shell, a collection box is arranged below the filter screen, the collection box is slidably connected to the shell, and a handle is fixedly connected to one end of the collection box.

[0008] When solid waste needs to be crushed, large pieces of solid waste are unloaded from the top of the shell, and fixed waste flows into the crushing component through the guide plate, and is crushed by the crushing component. After the crushing process, the fixed waste will fall onto the filter screen, and most of the dust and particles generated by the crushing will fall with the solid waste. At this time, the dust removal component starts to work, so that the nozzle can spray water mist, and the water mist will adhere to the dust, causing the dust to fall, thereby reducing the spread of dust. The particles will fall into the collection box through the filter screen, and the larger pieces of solid waste on the filter screen can be taken out through the sliding door set on one side of the shell.

[0009] A further improvement of the technical solution of the utility model is that the crushing component includes a first rotating shaft and a second rotating shaft, a plurality of crushing rollers are fixedly connected to the outer sides of the first rotating shaft and the second rotating shaft, a plurality of the first rotating shaft and the second rotating shaft are arranged along the length direction of the rotating shaft, the first rotating shaft is fixedly connected to the rotating shaft, disc gears are fixedly connected to the two ends of the first rotating shaft and the second rotating shaft, the second rotating shaft is rotatably connected to the rotating shaft, a support plate is arranged below the rotating shaft, a plurality of support columns are fixedly connected to the support plate, and a transmission gear is rotatably connected above the support column, and the transmission gears are respectively meshed with the disc gears.

[0010] The above-mentioned technical solution is adopted. In this solution, when solid waste falls from the guide plate onto the first rotating shaft and the second rotating shaft, the rotation of the motor will transmit power to the rotating shaft through the belt. The rotation of the rotating shaft will drive the first rotating shaft fixedly connected thereto to rotate. The rotation of the first rotating shaft will drive the fixedly connected disc gear to rotate, thereby driving the transmission gear meshing therewith to rotate. The rotation of the transmission gear will drive the disc gear to rotate, thereby driving the second rotating shaft to rotate. Through the first rotating shaft and the second rotating shaft, a number of devices are arranged along the length direction of the rotating shaft to achieve the purpose of reverse rotation of two adjacent rotating shafts. Such an arrangement can speed up the efficiency of crushing by the crushing component.

[0012] The above-mentioned technical solution is adopted, in which a water pump is set to transport the water in the water tank to the nozzle and spray it out in the form of water mist so that the water mist will adhere to the dust and cause the dust to fall. This can greatly reduce the proportion of dust generated by crushing in the air, thereby reducing the spread of dust and protecting the safety of workers.

[0013] A further improvement of the technical solution of the utility model is that a protective shell is fixedly connected to the first rotating shaft, and the protective shell is slidably connected to the support plate.

[0014] By adopting the above technical solution, a protective shell is provided in the solution to prevent foreign matter from entering between the first rotating shaft and the second rotating shaft during the crushing process, thereby causing the transmission gear to get stuck. This setting can effectively improve the crushing efficiency of the device, while also extending the service life of parts and reducing costs.

[0015] A further improvement of the technical solution of the utility model is that a pressure plate is fixedly connected and arranged below the guide plate, the pressure plates are arranged symmetrically, a wear-resistant layer is arranged on the surface of the pressure plate, and the material of the wear-resistant layer is tungsten carbide.

[0016] The above technical solution is adopted. In this solution, because the pressure plates are located at both ends of the crushing components, the crushing components will cause damage to the pressure plates when working. A wear-resistant layer is provided on the surface of the pressure plate to effectively prevent the solid waste from causing damage to the pressure plate during crushing.

[0017] A further improvement of the technical solution of the utility model is that the motor is electrically connected to the external control device.

[0018] The above technical solution is adopted, and the arrangement in the solution makes it easy to control the operation of the motor through an external control device.

[0032] In this embodiment, when it is necessary to crush the solid waste, the large pieces of solid waste are unloaded from the top of the shell 1, and the fixed waste flows into the crushing component through the guide plate 6, and is crushed by the crushing component. The fixed waste after the crushing process will fall onto the filter 7. At this time, most of the dust and particles generated by the crushing will fall with the solid waste. At this time, the dust removal component starts to work, so that the nozzle 18 can spray water mist. At this time, the water mist will adhere to the dust and cause the dust to fall, thereby reducing the diffusion of dust. The particles will fall into the collection box 8 through the filter 7, and the larger pieces of solid waste on the filter 7 can be taken out through the sliding door set on one side of the shell 1.

[0033] like Figure 3 As shown, in the present embodiment, preferably, the crushing component comprises a first rotating shaft 10 and a second rotating shaft 11, a plurality of crushing rollers 12 are fixedly connected to the outer sides of the first rotating shaft 10 and the second rotating shaft 11, a plurality of the first rotating shaft 10 and the second rotating shaft 11 are arranged along the length direction of the rotating shaft 4, the first rotating shaft 10 is fixedly connected to the rotating shaft 4, disc gears 16 are fixedly connected to both ends of the first rotating shaft 10 and the second rotating shaft 11, the second rotating shaft 11 is rotatably connected to the rotating shaft 4, a support plate 13 is arranged below the rotating shaft 4, a plurality of support columns 14 are fixedly connected to the support plate 13, a transmission gear 15 is rotatably connected above the support column 14, and the transmission gears 15 are respectively meshed with the disc gears 16.

[0034] When solid waste falls from the guide plate 6 onto the first rotating shaft 10 and the second rotating shaft 11, the rotation of the motor 2 will transmit power to the rotating shaft 4 through the belt 5. The rotation of the rotating shaft 4 will drive the first rotating shaft 10 fixedly connected thereto to rotate. The rotation of the first rotating shaft 10 will drive the fixedly connected disc gear 16 to rotate, thereby driving the transmission gear 15 meshing therewith to rotate. The rotation of the transmission gear 15 will drive the disc gear 16 to rotate, thereby driving the second rotating shaft 11 to rotate. The first rotating shaft 10 and the second rotating shaft 11 are provided along the length direction of the rotating shaft 4 with a plurality of means to achieve the purpose of reverse rotation of two adjacent rotating shafts. Such an arrangement can speed up the efficiency of crushing by the crushing components.

[0035] like Figure 1 As shown, preferably, the dust removal component includes a water tank 17, which is slidably connected to the shell 1, and a handle 9 is fixedly connected to one side of the water tank 17. A water pump is connected to the water tank 17, and a plurality of nozzles 18 are evenly arranged and fixedly connected to the shell 1, and the output end of the water pump is connected to the nozzle 18.

[0036] By setting up a water pump to transport the water in the water tank 17 to the nozzle 18 and spray it out in the form of water mist, the water mist will adhere to the dust and cause the dust to fall off. This can greatly reduce the proportion of dust generated by crushing in the air, thereby reducing the spread of dust and protecting the safety of workers.

[0038] like Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, a protective shell 19 is fixedly connected to the first rotating shaft 10, and the protective shell 19 is slidably connected to the support plate 13.

[0039] In this embodiment, the protective shell 19 is provided to prevent foreign matter from entering between the first rotating shaft 10 and the second rotating shaft 11 during the crushing process, thereby causing the transmission gear 15 to get stuck. This arrangement can effectively improve the crushing efficiency of the device, while also extending the service life of the parts and reducing costs.

[0040] Example 3

[0041] like Figure 2 As shown, based on Example 2, the utility model provides a technical solution: preferably, a pressure plate 20 is fixedly connected below the guide plate 6, the pressure plate 20 is symmetrically arranged, and a wear-resistant layer 21 is arranged on the surface of the pressure plate 20, and the material of the wear-resistant layer 21 is tungsten carbide.

[0042] In this embodiment, because the pressure plate 20 is located at both ends of the crushing component, the crushing component may cause damage to the pressure plate 20 when working. A wear-resistant layer 21 is provided on the surface of the pressure plate 20 to effectively prevent the solid waste from causing damage to the pressure plate 20 during crushing.

[0043] like Figure 1 As shown, in this embodiment, preferably, the motor 2 is electrically connected to the external control device.

[0044] This arrangement makes it easy to control the operation of the motor 2 through an external control device.

[0045] The working principle of the solid waste crushing and sorting device is described in detail below.

[0046] like Figure 1-4As shown, when the solid waste needs to be crushed, the large pieces of solid waste are unloaded from the top of the shell 1, and the fixed waste flows into the crushing component through the guide plate 6, and is crushed by the crushing component. The fixed waste after the crushing process will fall onto the filter 7. At this time, most of the dust and particles generated by the crushing will fall with the solid waste. At this time, the dust removal component starts to work, so that the nozzle 18 can spray water mist. At this time, the water mist will adhere to the dust and cause the dust to fall, thereby reducing the diffusion of the dust. The particles will fall into the collection box 8 through the filter 7, and the larger pieces of solid waste on the filter 7 can be taken out through the sliding door set on one side of the shell 1. When solid waste falls from the guide plate 6 to the top of the first rotating shaft 10 and the second rotating shaft 11, the rotation of the motor 2 will transmit power to the rotating shaft 4 through the belt 5. The rotation of the rotating shaft 4 will drive the first rotating shaft 10 fixedly connected thereto to rotate. The rotation of the first rotating shaft 10 will drive the fixedly connected disc gear 16 to rotate, thereby driving the transmission gear 15 meshing therewith to rotate. The rotation of the transmission gear 15 will drive the disc gear 16 to rotate, thereby driving the second rotating shaft 11 to rotate. The first rotating shaft 10 and the second rotating shaft 11 are provided along the length direction of the rotating shaft 4 with a plurality of gears that can realize the purpose of reverse rotation of two adjacent rotating shafts. This arrangement can speed up the efficiency of the crushing parts. By providing a water pump to transport the water in the water tank 17 to the nozzle 18 and spray it out in the form of water mist, the water mist will adhere to the dust and cause the dust to fall. This can greatly reduce the proportion of dust generated by crushing in the air, thereby reducing the diffusion of dust and protecting the safety of the staff. By providing a protective shell 19, foreign matter can be prevented from entering between the first rotating shaft 10 and the second rotating shaft 11 during the crushing process, thereby causing the transmission gear 15 to get stuck. This arrangement can effectively improve the crushing efficiency of the device, while also extending the service life of the parts and reducing costs. Because the pressing plate 20 is located at both ends of the crushing component, the crushing component will damage the pressing plate 20 when working. The wear-resistant layer 21 provided on the surface of the pressing plate 20 can effectively prevent the solid waste from causing damage to the pressing plate 20 during crushing. By providing an electrical connection between the motor 2 and the external control device, it is convenient to control the operation of the motor 2 through the external control device.

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
