Description
Technical Field
[0001] This invention relates to the field of compression device technology, and more particularly to a compression device for solid waste treatment. Background Technology
[0002] Solid waste compression devices are equipment used to compress solid waste, primarily to reduce waste volume for easier transportation, storage, and subsequent processing. Common types include horizontal compressors, vertical compressors, and crushing compressors, suitable for various scenarios such as municipal solid waste, industrial waste, construction waste, and hazardous waste. The advantages of compression devices include improved processing efficiency, reduced costs, space saving, and reduced environmental pollution risks.
[0003] However, existing horizontal compressors have a common problem during operation: due to gravity, waste tends to accumulate more at the bottom of the container during the feeding and pre-treatment stages. This causes the lower waste to be over-compressed under excessive pressure during horizontal compression, while the upper waste is under-compressed due to uneven pressure distribution. This uneven compression affects the overall compression effect, leading to loose waste structure, volume rebound, reduced transportation and disposal efficiency, and impacting the stability of subsequent processing steps. Summary of the Invention
[0004] To overcome the above-mentioned drawbacks, the present invention provides a compression device for solid waste treatment.

[0006] Furthermore, the feed shell is provided with mirror-distributed feed surfaces, the distance between the mirror-distributed feed surfaces gradually decreases from top to bottom, and mirror-distributed scraping plates are slidably connected to the pre-pressing plate. A spring is provided between the scraping plates and the pre-pressing plate, and the scraping plates are used to scrape off residual waste on the corresponding feed surfaces.
[0007] Furthermore, a mirror-distributed distribution shell is fixed to the side of the extrusion plate away from the compression shell. The distribution shell is connected to a uniformly distributed diversion pipe. A cooling chamber is provided inside the extrusion plate. The diversion pipe is connected to the cooling chamber. Both the distribution shell and the cooling chamber are connected to an external coolant circulation system through pipes.
[0008] Furthermore, the compression shell is provided with uniformly distributed heat dissipation plates.
[0009] Furthermore, the extrusion plate is provided with uniformly distributed extrusion heads on the side near the compression shell.
[0010] Furthermore, the extrusion heads corresponding to the same distribution shell are arranged in a triangular pattern to increase the stability of waste compression.
[0011] Furthermore, it also includes symmetrically and triangularly distributed connecting members, which are fixedly connected to the corresponding extrusion head, rotatably connected and communicating with the corresponding diverter pipe, and uniformly distributed connecting holes on the connecting members. The extrusion head is rotatably connected to the extrusion plate, and a circumferentially arrayed drive plate is fixedly connected inside the connecting member.
[0012] Furthermore, the side of the extrusion head away from the extrusion plate is hemispherical.
[0013] Furthermore, a pressure valve is fixedly connected inside the diversion pipe.
[0014] Furthermore, the extrusion head has evenly distributed protrusions slidably connected to its hemispherical portion, a fixed rod is fixedly connected to the extrusion head, a fixed ball is fixedly connected to the fixed rod, a tension spring is provided between the protrusions and the fixed ball, a piston is slidably connected to the fixed rod, the piston is slidably connected to the extrusion head, and a spring is provided between the piston and the fixed ball.
[0015] The beneficial effects of this invention are as follows: The invention pre-compresses solid waste vertically before horizontal compression using a pre-compression plate, reducing density differences in the vertical direction and improving the uniformity of horizontal compression, thus increasing subsequent transportation and disposal efficiency. A distribution shell injects coolant into the cooling chamber through a distribution pipe, and the coolant in the cooling chamber flows back to the external cooling system through pipes, thereby cooling the extrusion plate, reducing the probability of heat deformation, and improving the practicality of the device. Furthermore, the extrusion head pre-creates holes in the previously compressed solid waste, allowing subsequent compression to occur within these holes, thereby strengthening the bond between different compressed solid waste blocks and improving the stability of the solid waste during subsequent transportation and processing.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.
[0019] Example 1 A compression device for solid waste treatment is provided to address the problem of uneven longitudinal distribution of waste, which affects the quality of waste compression during the compression process.
[0020] like Figures 1-4As shown, the compression device includes a base plate 1, a frame 101 fixedly mounted on the base plate 1, two baffles 2 arranged in a mirror image on the base plate 1, and a compression shell 3 fixedly mounted on the base plate 1. A hydraulic door is provided on the right side of the compression shell 3 for opening the compression shell 3 and discharging the compressed solid waste after compression is completed. The frame 101, the two baffles 2, and the compression shell 3 are arranged sequentially from left to right. A power rod 4 is slidably connected to the frame 101. The power rod 4 is connected to an external hydraulic power system to provide power to the power rod 4. An extrusion plate 5 is fixedly mounted on the power rod 4 and is located between the two baffles 2. The two baffles 2 are jointly fixedly mounted with... The material feeding shell 6 has a cover plate 7 rotatably connected to its upper side. The cover plate 7 has an external power system for its rotation. The cover plate 7 is fixedly connected to a hydraulic push rod 8 via a mounting bracket. The telescopic end of the hydraulic push rod 8 is fixedly connected to a pre-compression plate 9. The pre-compression plate 9 is used to pre-compress the solid waste. The pre-compression plate 9 is located under the cover plate 7. The material feeding shell 6 has two material feeding surfaces 601 that are mirror-distributed to the left and right. The distance between the two material feeding surfaces 601 gradually decreases from top to bottom. The pre-compression plate 9 is slidably connected to two scraping plates 10 that are mirror-distributed to the left and right. A spring is provided between the scraping plate 10 and the pre-compression plate 9. The scraping plate 10 is used to scrape off the residual waste on the corresponding material feeding surface 601.
[0021] like Figure 2 , Figure 4 and Figure 5 As shown, two distribution shells 11 are fixed to the left side of the extrusion plate 5, which are distributed in a mirror image. The cross-section of the distribution shell 11 is triangular ring-shaped. The distribution shell 11 is connected to three evenly distributed diversion pipes 12, which are located at the three corners of the triangular ring shape of the distribution shell 11. A cooling chamber 13 is provided on the left side inside the extrusion plate 5. All diversion pipes 12 are connected to the cooling chamber 13. The distribution shell 11 and the cooling chamber 13 are connected to the external coolant circulation system through pipes. The pipe connected to the distribution shell 11 is the inlet pipe, and the pipe connected to the cooling chamber 13 is the outlet pipe. The compression shell 3 is provided with evenly distributed heat dissipation plates to help dissipate the heat generated during solid waste compression. The extrusion head 14 is provided on the side of the extrusion plate 5 near the compression shell 3. The extrusion head 14 on the same distribution shell 11 is triangularly distributed on the extrusion plate 5 to increase the stability of waste compression.
[0022] The working principle of the compression device in this embodiment is as follows: When this device is needed to compress solid waste, the user first controls the cover plate 7 to rotate, so that the cover plate 7 no longer obstructs the feed shell 6. Then, the user moves the transport vehicle full of solid waste to the vicinity of the feed shell 6 and gradually pours the solid waste into the feed shell 6. The solid waste moves downward under the guidance of the feed shell 6 and gradually accumulates on the bottom plate 1 until the solid waste accumulates to the lower side of the feed surface 601. Then, the user stops pouring solid waste into the feed shell 6 and controls the cover plate 7 to reverse and close the feed shell 6. The user then activates the hydraulic push rod 8. The telescopic end of the hydraulic push rod 8 drives the pre-compression plate 9 and the two scraper plates 10 to move downward together. During the process, the two scraper plates 10 scrape off the solid waste remaining on the feed surface 601. The two scraper plates 10 move towards each other under the pressure of the adjacent feed surfaces 601, while simultaneously squeezing the spring between the scraper plates 10 and the pre-compression plate 9. As the pre-compression plate 9 moves downward, it contacts the solid waste and gradually squeezes it downward, thereby pre-compressing the solid waste. The solid waste below the pre-compression plate 9 gradually becomes compacted until the pre-compression plate 9 moves downward to the lower end of the feed shell 6. The user controls the pre-compression plate 9 to stop moving. At this time, the solid waste pre-compression is completed. Through the above operation, the solid waste is pre-compressed on the vertical surface, reducing the density difference of the solid waste in the vertical direction.
[0023] After pre-compression, the user uses external power to move the power rod 4 to the right. The power rod 4 moves the extrusion plate 5 and its extrusion head 14 to the right together. The extrusion plate 5 extrudes and moves the solid waste to the right until the right side of the solid waste contacts the right hydraulic door on the compression shell 3. As the extrusion plate 5 continues to move to the right, it gradually extrudes the solid waste until the extrusion is complete. Then, the user controls the extrusion plate 5 to move to the left to reset. The left side of the compressed solid waste has a hole with the same shape as the extrusion head 14. The above steps are then repeated to continue compressing the solid waste. During the compression process, some of the second batch of solid waste is squeezed into the hole on the left side of the first batch of solid waste, thereby strengthening the connection between the two batches of solid waste. This continues until the compression shell 3 is full of compressed solid waste. Then, the user opens the right hydraulic door of the compression shell 3 and controls the extrusion plate 5 to push the compressed solid waste to the right out of the compression shell 3 for the next step. The device is then in use.
[0024] During the above process, the user simultaneously injects coolant into the front and rear distribution shells 11 through the external cooling system and pipes. Under the distribution of the distribution shells 11, the coolant is injected into the cooling chamber 13 through six branch pipes 12. The coolant in the cooling chamber 13 flows back to the external cooling system through pipes, thereby cooling the extrusion plate 5, reducing the probability of the extrusion plate 5 deforming due to heat, and improving the practicality of the device.
[0025] Example 2 This embodiment provides a compression device for solid waste treatment, which is a further improvement on Embodiment 1.
[0026] like Figures 4-7 As shown, it also includes symmetrically arranged triangular connecting parts 15, which are fixedly connected to the corresponding extrusion head 14. The connecting parts 15 are rotatably connected to and communicate with the corresponding diversion pipe 12. The connecting parts 15 are provided with uniformly distributed connecting holes 151. The extrusion head 14 is rotatably connected to the extrusion plate 5. A circumferentially arrayed drive plate 16 is fixedly connected inside the connecting parts 15. The drive plate 16 is spiral-shaped and is used to provide power when the liquid flows. The right side of the extrusion head 14 is hemispherical, which is used to make it easy for the extrusion head 14 to detach after compressing the solid waste. A pressure valve 17 is fixedly connected inside the diversion pipe 12. The specific structure of the pressure valve 17 is described in [details omitted]. Not shown in the figure, but only for illustration. Pressure valve 17 is located on the right side of the connection between the distributor pipe 12 and the cooling chamber 13. The upper hemisphere of the extrusion head 14 is slidably connected with evenly distributed convex strips 18, and the extrusion head 14 and the convex strips 18 are dynamically sealed. The extrusion head 14 is fixedly connected to a fixing rod 19, and the fixing rod 19 is fixedly connected to a fixing ball 20. A tension spring is provided between the convex strips 18 and the fixing ball 20. The fixing rod 19 is slidably connected to a piston 21, and the two are dynamically sealed. The piston 21 is slidably connected to the extrusion head 14, and a spring is provided between the piston 21 and the fixing ball 20. Hydraulic oil is injected between the piston 21 and the extrusion head 14, and the two are dynamically sealed.
[0027] The working principle of the compression device in this embodiment is as follows: When the solid waste is compressed once, the user increases the input pressure in the diversion pipe 12 through the external cooling system. The pressure in the diversion pipe 12 gradually increases, causing the coolant to continue flowing to the right through the pressure valve 17. The coolant flows to the right into the connecting member 15. The coolant entering between the connecting member 15 and the extrusion head 14 flows into the cooling chamber 13 through the connecting hole 151. When the coolant passes through the connecting member 15, it drives the rotating connecting member 15 to rotate through the drive plate 16. The connecting member 15 drives the extrusion head 14 to rotate, thereby loosening the gap between the extrusion head 14 and the compressed solid waste (making it easier for the solid waste compressed block to "demold"). As the coolant pressure continues to increase, the coolant squeezes and drives the piston 21 to move to the right, simultaneously compressing the spring between the piston 21 and the fixed ball 20. The piston 21 moves to the right and is hydraulically controlled on its right side. Oil compression causes the evenly distributed protrusions 18 on the connecting member 15 to gradually protrude outwards, simultaneously stretching the tension spring between the fixed ball 20 and the protrusions 18. This causes the right side of the hole on the left side of the solid waste to expand when the connecting member 15 rotates, forming a hole that is smaller on the outside and larger on the inside. After rotating for a period of time (this time is controlled by the user), the user controls the coolant in the cooling chamber 13 to restore pressure. The spring between the piston 21 and the fixed ball 20 drives the piston 21 to reset. The tension spring between the protrusions 18 and the fixed ball 20 drives the protrusions 18 to reset. Then, the compression plate 5 is controlled to reset to the left. The compression plate 5 drives the compression head 14 on it to disengage from the hole of the solid waste compression shell. When compressed again, the solid waste is squeezed into the hole of the previous batch of solid waste compression blocks and gradually compacted, thereby strengthening the bonding force between different solid waste compression blocks and improving the stability of the solid waste during subsequent transportation and processing.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
