Abstract
Description
Technical Field
[0001] This application relates to the field of solid waste treatment equipment, and more particularly to a solid waste treatment device. Background Technology
[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life and other activities. In the process of solid waste treatment, it is usually first subjected to preliminary crushing, and then cut into a certain size and shape according to the subsequent waste utilization production scenario to facilitate further recycling and reuse.
[0003] For example, Chinese Patent Publication No. CN215197200U discloses a solid waste treatment device, which includes a platform, a support fixed to the top right side of the platform, a support block fixed to the top of the support, and a feeding device installed on the top of the support block.
[0004] In the existing technology, the solid waste is granulated into small particles for transportation by the combination of crushing device and feeding device. The waste liquid remaining on the surface of the granulated solid waste is squeezed out and collected by the combination of feeding device, extrusion component and waste liquid collection device.
[0005] However, when solid waste is crushed in the processing tank, the resulting particles tend to accumulate in the internal cavity of the processing tank when it needs to be cut into different diameters in the slitting equipment. This reduces the efficiency of subsequent crushing and screening of solid waste. Furthermore, when the crushed solid particles are used for subsequent recycling and reprocessing, they need to be squeezed and filtered on different filter elements. In specific processing scenarios where different diameters of solid waste need to be crushed, different screening equipment is required for extrusion and cutting. This makes the subsequent processing of crushed particles cumbersome and extremely inconvenient, and cannot meet the needs of subsequent production and processing of particle waste of different diameters. Utility Model Content
[0006] To address the issue of solid waste accumulating in the treatment bin after treatment, which reduces the efficiency of subsequent compression and screening, and necessitates compression into particles of different diameters using different screening equipment, this application provides a solid waste treatment device.
[0007] The solid waste treatment equipment provided in this application adopts the following technical solution: it includes a treatment box, a crushing box, and crushing rollers. A feeding hopper is detachably installed on both sides of the bottom opening of the treatment box via bolts. A first screening disc and a second screening disc are fixedly installed on the two sets of feeding hoppers and the bottom openings of the treatment box, respectively. A reduction motor is fixedly installed on one side of one set of crushing boxes. A transmission rod is installed between the two sets of crushing rollers on the same straight line. A worm gear is fixedly sleeved on the transmission rod near the two sets of crushing boxes. A first stirring assembly and a second stirring assembly are rotatably installed on both sides inside the treatment box. Both the first stirring assembly and the second stirring assembly include a connecting shaft and stirring blades. A worm wheel is fixedly sleeved on the top of each of the two sets of connecting shafts. The outer edge of the worm wheel meshes with the outer edge of the worm gear on the same side. Cutting blades are rotatably connected to the bottom surfaces of the first screening disc and the second screening disc via rotating shafts.
[0008] By adopting the above technical solution, the first gearbox can shield and protect the two sets of transmission gears inside, while the second gearbox can shield and protect the worm and worm wheel inside, preventing particles from entering the tooth grooves and causing tooth jamming.
[0009] Preferably, a connecting plate is fixedly installed between the two sets of crushing boxes, and a first gearbox is fixedly installed on the opposite sides of the two sets of crushing boxes, the first gearbox being used to protect the transmission gears.
[0010] By adopting the above technical solution, the output end of the geared motor drives the crushing rollers in one set of crushing boxes, and the worm gear on the transmission rod drives the worm wheel at the top of the connecting shaft in the two sets of stirring components. This enables the first stirring component and the second stirring component to stir the crushed solid waste in the processing box and to perform gravity extrusion through the first screening plate and the second screening plate at the bottom.
[0011] Preferably, transmission gears are fixedly sleeved on the end shafts of the two sets of crushing rollers on the same side, and the outer edges of the two sets of transmission gears on the same side mesh with each other. Second gear boxes are fixedly installed on both sides of the top of the connecting plate, and the second gear boxes are used to protect the worm and the worm wheel.
[0012] By adopting the above technical solution, the crushing rollers in the two crushing boxes can be synchronously driven through the connection of the two crushing boxes via a transmission rod, thereby increasing the efficiency of solid waste crushing and processing.
[0013] Preferably, both ends of the transmission rod are fixedly connected to the end shafts of two sets of crushing rollers on the same straight line.
[0014] By adopting the above technical solution, the worm gears at the top of the connecting shafts of the two sets of stirring components are respectively driven by the worm gear on the transmission rod. This enables the first stirring component and the second stirring component to stir the crushed solid waste in the processing box and to perform gravity compression through the first screening plate and the second screening plate at the bottom.
[0015] Preferably, the top ends of the connecting shafts in the first stirring assembly and the second stirring assembly are rotatably connected to the processing tank and the connecting plate, respectively.
[0016] By adopting the above technical solution, after being subjected to gravity compression at the bottom of the first and second screening discs, the solid waste can be cut by the cutting blades below, thereby further cutting the solid waste passing through two sets of different screen holes, achieving one-time cutting to form two types of solid waste with different diameters.
[0017] Preferably, the diameter of the sieve holes on the first sieve disc is smaller than the diameter of the sieve holes on the surface of the second sieve disc.
[0018] By adopting the above technical solution, when the connecting shaft in the two sets of stirring components is synchronously driven by the upper worm gear and worm wheel, the cutting blades at the bottom of the connecting shaft in the stirring component can be cut by the lower cutting blades after being subjected to gravity compression at the bottom of the first and second screening discs.
[0019] Preferably, the connecting shafts at the center of the two sets of cutting blades are fixedly connected to the bottom ends of the connecting shafts in the first stirring assembly and the second stirring assembly, respectively.
[0020] In summary, when the connecting shaft in these two sets of stirring components is synchronously driven by the upper worm gear 52 and the worm wheel 62, the cutting blades 7 at the bottom of the connecting shaft in the stirring component are subjected to gravity compression at the bottom of the first screening disk 41 and the second screening disk 42, and can be cut by the lower cutting blades 7. The application includes at least one of the following beneficial technical effects:
[0021] This invention uses a geared motor output to drive the crushing rollers in one set of crushing boxes to crush solid waste introduced into the upper hopper. The two sets of crushing boxes are connected by a transmission rod, which allows the crushing rollers in the two sets of crushing boxes to be driven synchronously, thereby increasing the efficiency of solid waste crushing and processing. The worm gear on the transmission rod drives the worm wheel at the top of the connecting shaft in the two sets of stirring components. This allows the first stirring component and the second stirring component to agitate the crushed solid waste in the processing box and to perform gravity compression through the first screening plate and the second screening plate at the bottom. This agitation of the crushed solid waste in the processing box is achieved, avoiding accumulation on the screening plate and affecting the subsequent crushing and screening efficiency.
[0022] This invention utilizes the synchronous transmission of the connecting shaft in the two sets of stirring components via the upper worm gear and worm wheel. The cutting blades at the bottom of the connecting shaft in the stirring components are subjected to gravity compression at the bottom of the first and second screening discs, and can then be cut by the lower cutting blades. This further cuts the solid waste passing through the two sets of different screen holes, achieving one-time cutting to form two types of solid waste with different diameters, which facilitates the further processing of crushed waste into different granular shapes.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0029] This application discloses a solid waste treatment device, including a treatment box 1, a crushing box 2, and crushing rollers 3. The bottom two sides of the treatment box 1 are respectively detachably installed with feed hoppers 4 by bolts. The two sets of feed hoppers 4 are respectively fixedly installed with a first screening plate 41 and a second screening plate 42 at the bottom two sides of the treatment box 1. A reduction motor 5 is fixedly installed on one side of one set of crushing boxes 2. A transmission rod 51 is installed between the two sets of crushing rollers 3 located on the same straight line. A worm gear 52 is fixedly sleeved on the side of the transmission rod 51 near the two sets of crushing boxes 2.
[0030] Inside the processing box 1, a first stirring assembly 6 and a second stirring assembly 61 are rotatably installed on both sides. Both the first stirring assembly 6 and the second stirring assembly 61 include a connecting shaft and stirring blades. Worm gears 62 are fixedly sleeved on the top of the two sets of connecting shafts. The outer edge of the worm gear 62 meshes with the outer edge of the worm 52 on the same side. The bottom surfaces of the first screening disc 41 and the second screening disc 42 are rotatably connected to the cutting blades 7 through rotating shafts.
[0031] Solid waste is fed into the feed hopper with openings on both sides of the top of the treatment box 1. The solid waste is crushed by two sets of crushing rollers 3 in the crushing box 2 under the cooperation of the transmission gear 31. After crushing, the solid waste is fed into the treatment box 1 for further processing.
[0032] The output of the geared motor 5 drives the crushing rollers 3 in one of the crushing boxes 2 to crush the solid waste introduced into the upper hopper. The two crushing boxes 2 are connected by a transmission rod 51, so that the crushing rollers 3 in the two crushing boxes 2 can be driven synchronously, thereby increasing the efficiency of solid waste crushing and processing. The worm gear 52 on the transmission rod 51 drives the worm wheel 62 at the top of the connecting shaft in the two stirring components, so that the first stirring component 6 and the second stirring component 61 can agitate the crushed solid waste in the processing box 1, and perform gravity extrusion through the first screening plate 41 and the second screening plate 42 at the bottom. This agitates the crushed solid waste in the processing box 1 and avoids accumulation on the screening plate, which would affect the subsequent crushing and screening efficiency.
[0033] When the connecting shaft in the two sets of stirring components is synchronously driven by the upper worm gear 52 and worm wheel 62, the cutting blades 7 at the bottom of the connecting shaft in the stirring components can be cut by the lower cutting blades 7 after being squeezed by gravity at the bottom of the first screening disk 41 and the second screening disk 42. This further cuts the solid waste that has passed through the two sets of different screen holes, realizing the formation of two different diameter solid wastes in one cutting, which is convenient for further processing of the crushed waste into different granules.
[0034] refer to Figure 1 The equipment includes a connecting plate 20 fixedly installed between two sets of crushing boxes 2, and a first gearbox 21 fixedly installed on opposite sides of the two sets of crushing boxes 2. The first gearbox 21 is used to protect the transmission gear 31. Transmission gears 31 are fixedly sleeved on the shafts at the ends of the two sets of crushing rollers 3 on the same side. The outer edges of the two sets of transmission gears 31 on the same side mesh. A second gearbox 22 is fixedly installed on both sides of the top of the connecting plate 20. The second gearbox 22 is used to protect the worm 52 and worm wheel 62. The solid waste is crushed by the two sets of crushing rollers 3 in the crushing box 2 under the cooperation of the transmission gears 31. After crushing, the solid waste is introduced into the treatment box 1 for further processing. When the solid waste treatment equipment is in use, the first gearbox 21 can shield and protect the two sets of transmission gears 31 inside, while the second gearbox 22 can shield and protect the worm 52 and worm wheel 62 inside, to prevent particles from entering the tooth grooves and causing tooth jamming.
[0035] refer to Figures 1-3The transmission rod 51 is fixedly connected at both ends to the rotating shafts at the ends of two sets of crushing rollers 3 on the same straight line. The top ends of the connecting shafts in the first stirring assembly 6 and the second stirring assembly 61 are rotatably connected between the processing box 1 and the connecting plate 20, respectively. The two sets of crushing boxes 2 are connected by the transmission rod 51, so that the crushing rollers 3 in the two sets of crushing boxes 2 can be driven synchronously, thereby increasing the efficiency of solid waste crushing and processing. The worm gear 52 on the transmission rod 51 drives the worm wheel 62 at the top end of the connecting shaft in the two sets of stirring assemblies, so that the first stirring assembly 6 and the second stirring assembly 61 can stir the crushed solid waste in the processing box 1.
[0036] refer to Figure 3 In this process, the diameter of the sieve hole of the first sieve disk 41 is smaller than that of the sieve hole of the second sieve disk 42. The connecting shafts at the center of the two sets of cutting blades 7 are fixedly connected to the bottom ends of the connecting shafts in the first stirring assembly 6 and the second stirring assembly 61, respectively. When the connecting shafts in the two sets of stirring assemblies are synchronously driven by the upper worm gear 52 and the worm wheel 62, the cutting blades 7 at the bottom end of the connecting shaft in the stirring assembly can be cut by the lower cutting blades 7 after being squeezed by gravity at the bottom of the first sieve disk 41 and the second sieve disk 42.
[0037] The implementation principle of a solid waste treatment device in this application embodiment is as follows: When in use, the solid waste is first introduced into the feed hopper with openings on both sides of the top of the treatment box 1, and the solid waste is squeezed and crushed by two sets of crushing rollers 3 in the crushing box 2 under the cooperation of the transmission gear 31.
[0038] Meanwhile, the two sets of crushing boxes 2 are connected by a transmission rod 51, which enables the crushing rollers 3 in the two sets of crushing boxes 2 to be driven synchronously, thereby increasing the efficiency of solid waste crushing and processing. The worm gear 52 on the transmission rod 51 drives the worm wheel 62 at the top of the connecting shaft in the two sets of stirring components, so that the first stirring component 6 and the second stirring component 61 can stir the crushed solid waste in the processing box 1 and squeeze it by gravity through the first screening plate 41 and the second screening plate 42 at the bottom. This achieves the stirring of the crushed solid waste in the processing box 1, avoiding accumulation on the screening plate and affecting the subsequent crushing and screening efficiency.
[0039] When the connecting shaft in the two sets of stirring components is synchronously driven by the upper worm gear 52 and worm wheel 62, the cutting blades 7 at the bottom of the connecting shaft in the stirring components can be cut by the lower cutting blades 7 after being squeezed by gravity at the bottom of the first screening plate 41 and the second screening plate 42. This further cuts the solid waste that has passed through the two sets of different screen holes, realizing the formation of two different diameter solid wastes in one cutting, which is convenient for further processing of the crushed waste into different granules.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
