Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment technology, and specifically relates to an urban solid waste treatment device. Background Technology

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, construction, daily life, and other activities that cannot be utilized at a certain time and place and are discarded, polluting the environment. With the development of human society, waste is generated in the production, distribution, exchange, and consumption stages of socialized production. Common solid wastes include waste plastics, waste rubber, waste tires, and waste textiles.

[0003] With the advancement of the circular economy and the "dual carbon" approach, the recycling and treatment of solid waste plastics relies on mechanical extrusion to pre-compress their volume, followed by incineration for power generation, melting and granulation, or using technologies such as pyrolysis, hydrocracking, and enzymatic depolymerization to break down plastic macromolecules into monomers, chemical raw materials, or fuels, thus achieving resource recycling. However, traditional mechanical extrusion of plastic solid waste relies on a single press plate, especially when operating a single press plate in a large-size compaction box. This results in uneven compaction, with the edges of the compacted plastic blocks being tight and the center being loose. This can easily lead to the plastic blocks rebounding in volume or even breaking apart during long-distance transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and rationally designed urban solid waste treatment device in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A municipal solid waste treatment device, comprising: A strip-cutting mechanism for cutting plastic parts into strips; A compaction box and a compaction mechanism, wherein the compaction mechanism includes a central pressure column, a side pressure plate, a first compaction drive assembly, and a second compaction drive assembly. The output end of the first compaction drive assembly is drivenly connected to the central pressure column, and the output end of the second compaction drive assembly is drivenly connected to the side pressure plate. The side pressure plate is provided with a clearance groove. Under the drive of the second compaction drive assembly, the side pressure plate slides up and down with the central pressure column through the clearance groove. When the compaction mechanism compacts the plastic parts, the first compaction drive assembly drives the central pressure column to be located in the compaction box. Under the drive of the second compaction drive assembly, the side pressure plate compacts the plastic parts in the area between the compaction box and the central pressure column. The side pressure plate moves up to the initial position, and under the drive of the first compaction drive assembly, the central pressure column compacts the plastic parts in the extraction cavity.

[0006] As a further optimization of the present invention, a top plate is provided on the top of the frame of the compaction box, and the first compaction drive component includes a first lifting drive component, which is disposed above the central pressure column, and the output end of the first lifting drive component is connected to the central pressure column. The second compaction drive assembly includes a second lifting drive component and a guide rod. The second lifting drive component is disposed above the side pressure plate. The output end of the second lifting drive component is connected to the side pressure plate. The lower end of the guide rod is fixedly installed on the upper end of the side pressure plate, and the upper end of the guide rod passes through the top plate and is slidably connected to the top plate. The first lifting drive component and the second lifting drive component are respectively installed on the top plate.

[0007] As a further optimization of the present invention, a heating element is embedded in the central pressure column. The heating element is used to heat and shrink the plastic part that is attached to the surface of the central pressure column after the side pressure plate has completed the compaction operation of the plastic part in the area between the compaction box and the central pressure column.

[0008] As a further optimization of the present invention, the output end of the first lifting drive component is fixedly connected to a mounting base, and the first drive component is mounted on the mounting base. The output end of the first drive component is driven by a drive gear, which meshes with a driven gear. The drive gear and the driven gear are located at the lower end of the mounting base, respectively. The driven gear is fixedly mounted on the main shaft, the upper end of the main shaft is rotatably mounted on the mounting base, and the lower end of the main shaft is fixedly connected to the upper end of the central pressure column. Under the drive of the first drive component, the central pressure column rotates around the axis of the main shaft. The axial section of the central pressure column is an elliptical structure, and the upper end face of the central pressure column is lower than the lower end face of the side pressure plate during rotation.

[0009] As a further optimization of the present invention, the axis of the main shaft is parallel to and not collinear with the axis of the central pressure column, and under the drive of the first driving member, the central pressure column rotates eccentrically around the axis of the main shaft.

[0010] As a further optimization of the present invention, the lower end of the side pressure plate is provided with a flange portion, which is located at the edge of the relief groove.

[0011] As a further optimization of the present invention, a door is provided on one side of the compaction box, and a transition block is fixedly connected to the lower outer end of the door. The transition block is rotatably connected to a fixed seat, and the fixed seat is fixedly installed on the base. An opening drive assembly is driven to the outer end of the door. The opening drive assembly is used to control the opening and closing state of the door. When the door is rotated to the opening position under the drive of the opening drive assembly, the height of the upper surface of the door is lower than the upper surface of the base.

[0012] As a further optimization of the present invention, the box opening drive assembly includes a third telescopic drive component, a support block and a horizontal shaft. The third telescopic drive component is rotatably mounted on the frame of the compaction box. The output end of the third telescopic drive component is rotatably connected to the horizontal shaft. The support block is fixedly mounted on the box door. The horizontal shaft passes through the support block and is rotatably connected to the support block. When the box door is in the open position, the lower end face of the support block abuts against the ground for support.

[0013] As a further optimization of the present invention, the strip cutting mechanism includes a second driving member, a transmission belt, a driven pulley, a winch roller, a discharge hopper, and a discharge channel. The output end of the second driving member is drivenly connected to a driving pulley, which is drivenly connected to a driven pulley via the transmission belt. The driven pulleys are arranged in pairs, and the output ends of the paired driven pulleys are respectively fixedly connected to winch rollers. Winch rollers are provided with winch teeth, and the winch teeth on the two winch rollers mesh. The winch teeth are located below the discharge hopper, and the lower end of the discharge hopper has a discharge port. The plastic parts fall into the winch cutting area of ​​the winch teeth through the discharge port. The cut plastic strips are then transported to the compaction box through the discharge channel.

[0014] As a further optimization of the present invention, the discharge channel includes a fixed channel, a sliding channel, and a sliding drive. The input end of the fixed channel is used to receive the cut plastic parts. The output end of the fixed channel is slidably connected to the sliding channel, and the sliding channel is sleeved on the output end of the fixed channel. The output end of the sliding drive is fixedly connected to the sliding channel. The sliding drive is used to drive the sliding channel to slide and adjust the position of the discharge port of the sliding channel.

[0015] The present invention has at least the following beneficial effects: The present invention provides an urban solid waste treatment device, including a strip cutting mechanism, a compaction box, and a compaction mechanism. The strip cutting mechanism is used to cut plastic parts into strips. The compaction mechanism includes a central pressure column, side pressure plates, a first compaction drive assembly, and a second compaction drive assembly. The first compaction drive assembly drives the central pressure column to move down into the compaction box, so that a first compaction area is formed between the compaction box and the central pressure column. This allows the side pressure plates to compact the first compaction area. Then, the central pressure column is removed, and plastic parts are put into the removal cavity. The central pressure column moves down to compact the plastic in the removal cavity, thereby achieving the overall regional compaction of the plastic block, making the compacted plastic block compact and uniform, and not easy to fall apart. Moreover, the cutting mechanism twists the plastic parts into strips. A mounting base is set at the output end of the first lifting drive component. The first drive component on the mounting base drives the drive gear. The drive gear meshes with the driven gear, thereby causing the main shaft to drive the central pressure column to rotate. With the help of the rotation of the elliptical structure of the central pressure column, the plastic parts in the first compaction area are pushed circumferentially. The circumferential pushing force of the central pressure column will cause the strip plastic parts to twist along the first compaction area, so that the originally simply stacked plastic strips interweave and wrap more fully.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] In the description of the embodiments of this application, it should be understood that the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship that the product of this application is usually placed in, or the orientation or positional relationship that is commonly understood by those skilled in the art. They are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides an urban solid waste treatment device, comprising: A strip-cutting mechanism 1 is used to cut plastic parts into strips; The compaction box 2 and the compaction mechanism 3 include a central pressure column 31, a side pressure plate 32, a first compaction drive assembly 301 and a second compaction drive assembly 302. The output end of the first compaction drive assembly 301 is drivenly connected to the central pressure column 31, and the output end of the second compaction drive assembly 302 is drivenly connected to the side pressure plate 32. The side pressure plate 32 is provided with a clearance groove 317. Under the drive of the second compaction drive assembly 302, the side pressure plate 32 slides up and down with the central pressure column 31 through the clearance groove 317. When the compaction mechanism 3 compacts the plastic parts, the first compaction drive assembly 301 drives the central pressure column 31 to be located in the compaction box 2. Under the drive of the second compaction drive assembly 302, the side pressure plate 32 compacts the plastic parts placed in the area between the compaction box 2 and the central pressure column 31. The side pressure plate 32 moves up to the initial position, and under the drive of the first compaction drive assembly 301, the central pressure column 31 compacts the plastic parts placed in the extraction cavity.

[0021] In the above embodiment, the plastic parts are cut into strips by the strip cutting mechanism 1. The plastic parts in urban solid waste include beverage bottles, packaging boxes, non-food packaging bottles (such as cosmetic bottles, detergent bottles, pesticide bottles), etc. Cutting them into strips exposes the air inside the bottle, and can efficiently compress and release air during compression. Furthermore, the first compaction drive assembly 301 first drives the central pressure column 31 to move down into the compaction box 2, making the area between the compaction box 2 and the central pressure column 31 the first compaction area, see reference. Figure 6 In the diagram, the long dashed line indicates the inner wall boundary of the compaction box 2. The first compaction area is the region between the long dashed line and the central pressure column 31. At this point, the cut plastic part is placed into the first compaction area. Driven by the second compaction drive assembly 302, the side pressure plate 32 moves downward to compact the plastic part in the first compaction area. Then, the second compaction drive assembly 302 drives the side pressure plate 32 upward to its initial position. At this time, the first compaction drive assembly 301 drives the central pressure column 31 upward, so that the central pressure column 31 moves from... The plastic part is extracted, forming an extraction cavity within it. This extraction cavity serves as the second compaction area, which is the same space previously occupied by the central pressure column 31 in the compaction box 2. The plastic part is then placed into this extraction cavity, and the central pressure column 31 is driven downward by the first compaction drive assembly 301 to compact the plastic part in the second compaction area. This achieves regional compaction of the plastic part in the compaction box 2, resulting in a compacted and uniform plastic block that is less prone to crumbling.

[0022] It should be further explained that the plastic parts are not directly shredded, but rather twisted into strips. The plastic parts can be interlocked and bound together by wrapping around each other, forming a mesh-like structure after being compacted. This prevents the plastic parts from easily coming loose during transportation and reduces the probability of them falling apart.

[0023] Continue to refer to Figure 1 and Figure 2 A side guard plate 22 is provided on the upper side of the compaction box 2. The notch of the side guard plate 22 is the position where the cutting mechanism 1 supplies plastic parts into the compaction box 2. The side guard plate 22 provides lateral protection to prevent the plastic parts from falling out of the compaction box 2. At the same time, the side guard plate 22 provides guidance and constraint for the up and down movement of the side pressure plate 32.

[0024] It should be noted that the surface of the central pressure column 31 is coated with a Teflon coating. The low friction, non-stick, high temperature resistance and chemical stability of Teflon (polytetrafluoroethylene) are used to reduce the friction between the central pressure column 31 and the plastic part, so that when the central pressure column 31 is withdrawn, it will not take away the plastic part of the first compaction area.

[0025] For example, see [link to relevant documentation]. Figure 1 , Figure 3and Figure 4 The top of the frame of the compaction box 2 is provided with a top plate 23. The first compaction drive assembly 301 includes a first lifting drive component 311. The first lifting drive component 311 is located above the central pressure column 31. The output end of the first lifting drive component 311 is connected to the central pressure column 31. The second compaction drive assembly 302 includes a second lifting drive component 321 and a guide rod 322. The second lifting drive component 321 is disposed above the side pressure plate 32. The output end of the second lifting drive component 321 is connected to the side pressure plate 32. The lower end of the guide rod 322 is fixedly installed on the upper end of the side pressure plate 32. The upper end of the guide rod 322 passes through the top plate 23 and is slidably connected to the top plate 23. The first lifting drive component 311 and the second lifting drive component 321 are respectively installed on the top plate 23.

[0026] For example, the first lifting drive component 311 is a hydraulic telescopic cylinder, an electric telescopic cylinder, or a power telescopic cylinder, and the second lifting drive component 321 is a hydraulic telescopic cylinder, an electric telescopic cylinder, or a power telescopic cylinder; no limitation is made here.

[0027] For example, a heating element (not shown in the figure) is embedded in the central pressure column 31. The heating element is used to heat and shrink the plastic part attached to the surface of the central pressure column 31 after the side pressure plate 32 has completed the compaction operation on the plastic part in the area between the compaction box 2 and the central pressure column 31. For example, the heating element is a heating wire, which is wound and embedded in the slot of the central pressure column 31. The slot opening is located at the upper end of the central pressure column 31, and the slot opening is sealed with a waterproof cap.

[0028] After the side pressure plate 32 completes the compaction of the plastic parts in the first compaction area, the strip-shaped plastic parts are intertwined and hooked together. At this time, when the central pressure column 31 is removed, the heating element conducts heat to the surface of the central pressure column 31, causing the plastic parts adhering to the surface of the central pressure column 31 to soften and shrink due to heat. The shrinking plastic strips will actively "hug" the surrounding strip-shaped plastic parts, that is, the plastic parts on the surface of the central pressure column 31 will generate a contraction force away from the central pressure column 31, thereby reducing the squeezing force of the plastic parts on the central pressure column 31, and reducing the frictional resistance when removing the central pressure column 31. Moreover, the rebound characteristics of the shrunken plastic parts after cooling are weakened compared with the rebound characteristics of the unsoftened and shrunken plastic parts, ensuring that the plastic parts in the first compaction area are firmly compacted.

[0029] It should be noted that the heating temperature of the heating element on the surface of the central pressure column 31 is lower than the melting temperature of the plastic part, so that the plastic part only shrinks upon heating. For example, if the plastic part is made of polyethylene, whose shrinkage temperature is 80-120℃, then the heating temperature of the heating element on the surface of the central pressure column 31 is lower than 80℃. As another example, if the plastic part is made of polyvinyl chloride, whose shrinkage temperature is 60-100℃, then the heating temperature of the heating element on the surface of the central pressure column 31 is lower than 60℃. Therefore, the heating temperature of the heating element on the surface of the central pressure column 31 is set according to the material of the plastic part, and is not limited here.

[0030] For example, see [link to relevant documentation]. Figure 4 and Figure 5 The output end of the first lifting drive component 311 is fixedly connected to a mounting base 312. A first drive component 313 is mounted on the mounting base 312. The output end of the first drive component 313 is driven by a drive gear 314, which meshes with a driven gear 315. The drive gear 314 and the driven gear 315 are located at the lower end of the mounting base 312. The driven gear 315 is fixedly mounted on a main shaft 316. The upper end of the main shaft 316 is rotatably mounted on the mounting base 312. The lower end of the main shaft 316 is fixedly connected to the upper end of a central pressure column 31. Under the drive of the first drive component 313, the central pressure column 31 rotates around the axis of the main shaft 316. (Continue reading...) Figure 6 The axial section of the central pressure column 31 is elliptical, and when rotating, the upper end face of the central pressure column 31 is lower than the lower end face of the side pressure plate 32.

[0031] For example, the first driving element 313 is a drive motor.

[0032] Driven by the first driving member 313, the driving gear 314 meshes with the driven gear 315, causing the main shaft 316 to drive the central pressure column 31 to rotate. At this time, with the help of the rotation of the elliptical central pressure column 31, the plastic parts in the first compaction area are pushed circumferentially. The circumferential pushing force of the central pressure column 31 will cause the strip plastic parts to twist along the first compaction area, so that the originally simply stacked plastic strips interweave and wrap more fully. Moreover, the circumferential pushing force of the elliptical central pressure column 31 on the plastic parts causes the wrapped plastic strips to squeeze each other in advance to expel some of the gap air, so that the side pressure plate 32 can compact the plastic strips more efficiently during the compaction operation.

[0033] For example, see [link to relevant documentation]. Figure 5 and Figure 6 The axis of the main shaft 316 is parallel to but not collinear with the axis of the central pressure column 31. Under the drive of the first driving member 313, the central pressure column 31 rotates eccentrically around the axis of the main shaft 316. Thus, when the main shaft 316 drives the central pressure column 31 to rotate eccentrically, as... Figure 6As shown, the short dashed line indicates the boundary area of ​​the rotation trajectory of the central pressure column 31, which increases the circumferential pushing range of the central pressure column 31.

[0034] It should be noted that, as Figure 5 As shown, the lower end of the central pressure column 31 has an inverted conical surface structure.

[0035] Among them, such as Figure 4 and Figure 5 As shown, the lower end of the side pressure plate 32 is provided with a flange 323, which is located at the edge of the relief groove 317. This allows the central pressure column 31 to be effectively removed from its surface by the flange 323 as it adheres to the surface of the central pressure column 31 after the compaction operation, driven upward by the first lifting drive 311 to its initial position. Furthermore, as the side pressure plate 32 presses down, the flange 323 also compacts the plastic parts, creating a chamfer at the upper edge of the extraction cavity formed after compaction, thus facilitating the subsequent falling of plastic parts into the extraction cavity.

[0036] For example, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 7 The compaction box 2 has a door 4 on one side. A connecting block 45 is fixedly connected to the lower outer end of the door 4, and the connecting block 45 is rotatably connected to a fixed base 44. The fixed base 44 is fixedly mounted on the base 21. An opening drive assembly is drively connected to the outer end of the door 4. The opening drive assembly controls the opening and closing state of the door 4. When the door 4 rotates to the opening position under the drive of the opening drive assembly, the upper surface of the door 4 is lower than the upper surface of the base 21. Therefore, under the drive of the opening drive assembly, the door 4 opens laterally, and a mechanical gripper removes the plastic block. During removal, the door 4 is in a horizontal position to provide a platform for dragging the removed plastic block. After removal, the door 4 can be closed. Figure 7 As shown, door 4 is in the closed position.

[0037] The box-opening drive assembly includes a third telescopic drive component 41, a support block 42, and a horizontal shaft 43. The third telescopic drive component 41 is rotatably mounted on the frame of the compaction box 2. The output end of the third telescopic drive component 41 is rotatably connected to the horizontal shaft 43. The support block 42 is fixedly mounted on the box door 4. The horizontal shaft 43 passes through the support block 42 and is rotatably connected to it. When the box door 4 is in the open position, the lower end face of the support block 42 abuts against the ground for support. Through the transmission of the third telescopic drive component 41 via the horizontal shaft 43 and the support block 42, the box door 4 rotates around the rotation axis of the transition block 45 and the fixed seat 44 to open the box door 4. The opened box door 4 is stably maintained in the open state with the auxiliary support of the support block 42.

[0038] The third telescopic drive component 41 can be a hydraulic telescopic cylinder, an electric telescopic cylinder, or a power telescopic cylinder; no specific limitation is made here.

[0039] It should be noted that further reading is required. Figure 1 , Figure 2 and Figure 8 The cutting mechanism 1 includes a second driving member 11, a transmission belt 12, a driven pulley 13, a winch roller 14, a hopper 16, and a discharge channel 17. The output end of the second driving member 11 is connected to a driving pulley (not shown in the figure), and the driving pulley is connected to the driven pulley 13 via the transmission belt 12. The driven pulleys 13 are arranged in pairs, and the output ends of the paired driven pulleys 13 are respectively fixedly connected to the winch roller 14. The winch roller 14 is provided with winch teeth 15, and the winch teeth 15 on the two winch rollers 14 mesh. The winch teeth 15 are located below the hopper 16, and the lower end of the hopper 16 is provided with a discharge port 161. The plastic parts fall into the winch cutting area of ​​the winch teeth 15 through the discharge port 161. The cut plastic strips are then transported to the compaction box 2 through the discharge channel 17.

[0040] Continue reading Figure 9 The discharge channel 17 includes a fixed channel 171, a sliding channel 172, and a sliding drive 173. The input end of the fixed channel 171 is used to receive the cut plastic parts. The output end of the fixed channel 171 is slidably connected to the sliding channel 172, and the sliding channel 172 is sleeved on the output end of the fixed channel 171. The output end of the sliding drive 173 is fixedly connected to the sliding channel 172. The sliding drive 173 is used to drive the sliding channel 172 to slide and adjust the position of the discharge port of the sliding channel 172.

[0041] The outlet of the sliding channel 172 is the end of the sliding channel 172 that is away from the fixed channel 171. The position of the outlet of the sliding channel 172 is adjusted by the sliding drive component 173 so that the sliding channel 172 can smoothly feed plastic parts into the first compaction area and the second compaction area respectively.

[0042] It should be noted that, in use, this type of urban solid waste treatment device, firstly, driven by the first lifting drive component 311, the central pressure column 31 moves down into the compaction box 2 and abuts against the bottom support 21. At this time, if... Figure 3 and Figure 4As shown, the lower end face of the side pressure plate 32 is higher than the upper end face of the central pressure column 31. The central pressure column 31 and the compaction box 2 form a first compaction area. At this time, under the drive of the sliding drive 173, the sliding channel 172 slides to the discharge port position directly facing the first compaction area. At this time, the recycled plastic parts are put into the discharge hopper 16 and fall into the cutting area of ​​the auger 15 through the discharge port 161 and are cut into strips. They then fall into the first compaction area through the fixed channel 171 and the sliding channel 172 in sequence. Then, driven by the first driving member 313, the driving gear 314 meshes with the driven gear 315, causing the main shaft 316 to drive the central pressure column 31 to rotate. With the help of the rotation of the elliptical structure of the central pressure column 31, the plastic parts in the first compaction area are pushed circumferentially. The circumferential pushing force of the central pressure column 31 will cause the strip-shaped plastic parts to twist along the first compaction area, so that the originally simply stacked plastic strips interweave and wrap more fully. Next, driven by the second lifting driving member 321, the side pressure plate 32 is moved down to compact the plastic parts in the first compaction area, and under the reverse drive of the second lifting driving member 321, the side pressure plate 32 is moved up to the initial position. Then, under the heating of the heating element, the plastic part on the surface of the central pressure column 31 is heated and softened by the central pressure column 31, causing the plastic part to shrink due to heat. Thus, under the drive of the first lifting drive 311, the central pressure column 31 is smoothly pulled out, and under the drive of the sliding drive 173, the sliding channel 172 is moved outward to the discharge port facing the extraction cavity, so that the plastic part can be put into the second compaction area. Then, driven by the first lifting drive 311, the central pressure column 31 moves down to compact the plastic parts in the second compaction area, so as to achieve regional compaction of the plastic block. After compaction, the box door 4 opens to the side under the drive of the third telescopic drive 41, so as to remove the plastic block from the compaction box 2 with the help of mechanical grippers. Then, the third telescopic drive 41 is driven in the opposite direction to close the box door 4, and the above action is repeated to carry out the compaction operation of the next plastic block.

[0043] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
