Description

Technical Field

[0001] This utility model belongs to the field of solid waste treatment technology and relates to a solid waste compression device. Background Technology

[0002] Solid waste refers to solid, semi-solid, and gaseous items and substances placed in containers that have lost their original utilization value or have been discarded or abandoned even if they have not lost their utilization value, as well as items and substances that are included in waste management as stipulated by laws and administrative regulations.

[0003] Chinese utility model patent CN213704637U discloses a compression device for solid waste recycling and processing, including a shell, support feet, feeding trough, solid storage box, liquid storage tank, conveying device, cylinder, and pressure plate. The device features a conveying device in the middle of the compression unit, which controls the movement and discharge of waste. Waste to be compressed is fed into the feeding box of the conveying device through the feeding trough. The feeding box moves to the bottom of the pressure plate, where it compresses the waste inside, causing solid-liquid separation. Liquid waste is guided into the liquid storage tank through a water pipe. A box is located at the top of the feeding box; by moving the box forward, it pushes the compressed solid waste from the bottom plate into the solid storage box for storage. The device offers good automation and reduces manual operation for users. When solid waste contains contents, the above-mentioned technical solutions cannot effectively remove the contents, causing the contents to be squeezed together with the solid waste, affecting the recycling and sorting effect of solid waste, and failing to maximize the compression of the space occupied by the waste and further compact the density of the waste. Utility Model Content

[0004] To address the problem that existing technical solutions often fail to effectively remove contents from solid waste, leading to the contents being compressed together and hindering recycling and sorting, this invention proposes a solid waste compression device. This device effectively solves the problem of existing solutions failing to properly remove contents from solid waste, resulting in the contents being compressed together and affecting recycling and sorting.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A solid waste compression device includes a housing. Connecting columns are provided at the four corners of the upper side of the housing. A top plate is provided on the upper side of the four connecting columns. The housing has an upper pressure plate that can move up and down within the housing. A lower pressure plate is located below the upper pressure plate and is situated within the housing. The upper and lower pressure plates are the same size and shape and are positioned vertically in correspondence. The lower side of the upper pressure plate has a rectangular array of multiple pressure needles. The lower pressure plate has multiple water-filtering holes that extend vertically through it. The number of water-filtering holes is the same as the number of pressure needles, and their vertical positions correspond one-to-one. The top plate has a driving component for pushing the upper pressure plate to move up and down.

[0006] Furthermore, the drive assembly includes an electric push rod disposed on the side of the top plate and a power supply. The electric push rod is electrically connected to the power supply, and the output shaft of the electric push rod passes through the top plate and is connected to the upper side of the upper pressure plate.

[0007] Furthermore, two first guide posts are symmetrically arranged on the left and right sides of the upper pressure plate, and two first guide seats are symmetrically arranged on the left and right sides of the top plate. The two first guide posts pass through the top plate and are respectively inserted into the two first guide seats.

[0008] Furthermore, four second guide seats are arranged in a rectangular array on the inner side of the upper pressure plate. Each second guide seat is inserted with a second guide post. The lower ends of the four second guide posts pass through the upper pressure plate and are connected to a pressure plate. The pressure plate has multiple through holes for inserting the pressure pins. The upper ends of the second guide posts pass through the second guide seats and are provided with anti-dislodgement caps. The top plate can move downward with the second guide posts and contact the upper side of the second guide seats.

[0009] Furthermore, a door is hinged to the front side of the housing, and two sets of limiting components are provided on the front side of the door to connect the door to the housing.

[0010] Furthermore, the limiting component includes a limiting plate that is rotatably connected to the front side of the box door, and a limiting buckle is provided on the front side of the housing. The limiting plate can be rotatably inserted into the limiting buckle.

[0011] Furthermore, a locking block is detachably connected between the upper pressure plate and the pressure plate to prevent the pressure plate from moving up and down.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model achieves compression and separation of solid waste through an upper pressure plate, a lower pressure plate, a pressure needle, and a drive assembly, thereby improving the processing efficiency of solid waste. The squeezed solid waste contents can pass through the water filter holes on the lower pressure plate and be discharged to the outside, preventing the contents from accumulating inside the shell and ensuring the reliability of the device during use. This utility model achieves the cleaning of solid waste stuck on the ejector pin through the pressure plate, the first guide post and the first guide seat, which improves the efficiency of workers in collecting solid waste. At the same time, it prevents solid waste from affecting the subsequent use of the upper pressure plate and the pressure pin, thus ensuring the working efficiency of the device during use. This utility model achieves external protection of the housing through the box door and limiting components, preventing fragments generated when solid waste in the housing is compressed from flying out and causing injury to surrounding workers, thus ensuring the safety and reliability of the device during use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] A solid waste compression device includes a housing 1. Connecting columns 8 are welded to the four corners of the upper side of the housing 1, and supporting feet are provided at the four corners of the lower side of the housing 1. A top plate 7 is welded to the upper sides of the four connecting columns 8. The housing 1 is provided with an upper pressure plate 2 that can move up and down within the housing 1. A lower pressure plate 3 located inside the housing 1 is clamped below the upper pressure plate 2. The upper pressure plate 2 and the lower pressure plate 3 are the same size and shape and are arranged vertically in correspondence. Multiple pressure needles 5 arranged in a rectangular array are welded to the lower side of the upper pressure plate 2. Multiple water-filtering holes 301 are opened vertically through the lower pressure plate 3. The number of water-filtering holes 301 is the same as the number of pressure needles 5, and their vertical positions correspond one-to-one. A driving component for pushing the upper pressure plate 2 to move up and down is provided on the top plate 7.

[0017] In this embodiment, the drive assembly includes an electric push rod 10 disposed on the upper side of the top plate 7 and a power supply 17. The electric push rod 10 is electrically connected to the power supply 17, and the output shaft of the electric push rod 10 passes through the top plate 7 and is connected to the upper side of the upper pressure plate 2. Preferably, the electric actuator 10 can be replaced by a hydraulic actuator to achieve the same technical effect, and the electric actuator 10 can be directly connected to an external AC power outlet. The power supply 17 can be adjusted or omitted according to the actual use case.

[0018] In this embodiment, two first guide posts 6 are symmetrically arranged on the upper side of the upper pressure plate 2, and two first guide seats 9 are symmetrically arranged on the upper side of the top plate 7. The two first guide posts 6 pass through the top plate 7 and are respectively inserted into the two first guide seats 9.

[0019] Preferably, there can be multiple first guide posts 6 and first guide seats 9, which are arranged in a rectangular or circular array on the upper side of the upper pressure plate 2. This ensures the balance of the upper pressure plate 2 under pressure, prevents deformation of the upper pressure plate 2, and extends the service life of the upper pressure plate 2. The overall dimensions of the above embodiment are 60-100 cm in length, 60-100 cm in width, and 80-150 cm in height; the downward pressure is 10-50 tons; the power of the electric actuator 10 is 2000-5000 watts; and the power supply 17 is 12-380 volts. These dimensional parameters can be adjusted according to actual conditions. Where AC power is readily available... The working principle of the above embodiments is as follows: In use, the operator places solid waste on the upper side of the lower pressure plate 3. Then, the operator controls the electric push rod 10 to push the upper pressure plate 2 downward, pressing down the solid waste on the upper side of the lower pressure plate 3. When the upper pressure plate 2 presses down on the solid waste, the pressure pins 5 on the lower side of the upper pressure plate 2 can penetrate the fixed waste, so that the upper pressure plate 2 can squeeze the contents of the solid waste while pressing down on the solid waste, improving the squeezing effect when squeezing the solid waste, separating the solid-liquid and solid-gas components, and thus improving the compaction efficiency of the solid waste. The squeezed solid waste contents can pass through the water filter holes 301 on the lower pressure plate 3 and be discharged to the outside, preventing the contents from accumulating in the shell 1 and ensuring the reliability of the device during use.

[0020] Example 2 differs from Example 1 in that: The upper pressure plate 2 has four second guide seats 12 arranged in a rectangular array on its upper side. Each second guide seat 12 has a second guide post 11 inserted into it. The lower ends of the four second guide posts 11 pass through the upper pressure plate 2 and are connected to a pressure plate 4. The pressure plate 4 has multiple through holes 401 for inserting the pressure needle 5. The upper ends of the second guide posts 11 pass through the second guide seats 12 and are provided with anti-detachment caps 13. The top plate 7 can move downward with the second guide posts 11 and contact the upper side of the second guide seats 12.

[0021] The working principle of this embodiment is as follows: When the upper pressure plate 2 rises after squeezing the fixed waste, some of the fixed waste may get stuck on the pressure needle 5. At this time, the pressure plate 4 can be pushed downward under the action of gravity. While the pressure plate 4 is pushed downward, it can push the solid waste stuck on the pressure needle 5 away from the pressure needle 5, which improves the efficiency of the staff in collecting solid waste. At the same time, it prevents the solid waste from affecting the subsequent use of the upper pressure plate 2 and the pressure needle 5, and ensures the working efficiency of the device when in use.

[0022] Preferably, there can be multiple second guide posts 11 and second guide seats 12. Multiple second guide posts 11 and second guide seats 12 are arranged in a rectangular array or a circular array on the upper side of the pressure plate 4, thereby ensuring the balance of the pressure plate 4 under pressure, preventing the pressure plate 4 from deforming, and extending the service life of the pressure plate 4.

[0023] Example 3 differs from Example 1 in that: The front side of the housing 1 is hinged with a door 14, and the front side of the door 14 is provided with two sets of limiting components that connect the door 14 to the housing 1.

[0024] In this embodiment, the limiting component includes a limiting plate 15 that is rotatably connected to the front side of the box door 14, and a limiting buckle 16 is provided on the front side of the housing 1. The limiting plate 15 can be rotatably inserted into the limiting buckle 16.

[0025] The working principle of this embodiment is as follows: After the staff puts the solid waste into the upper side of the lower pressure plate 3, the staff rotates the box door 14 to the front side of the shell 1, and then rotates the limiting plate 15 to insert it into the limiting buckle 16, thereby realizing the fixed connection between the box door 14 and the shell 1, thus preventing the fragments generated by the solid waste in the shell 1 when being compressed from flying out and causing injury to the surrounding staff, and ensuring the safety and reliability of the device during use.

[0026] Example 4 differs from Example 1 in that: The upper pressure plate 2 and the pressure plate 4 are detachably connected by a locking block 18 that prevents the pressure plate 4 from moving up and down.

[0027] When the compressed solid waste needs to remain intact and not be punctured (such as a beverage bottle without a cap), the staff can place the locking block 18 between the upper pressure plate 2 and the pressure plate 4. At this time, the pressure plate 4 cannot move up or down, and the pressure needle 5 is located in the through hole 401 of the pressure plate 4, and cannot come into contact with the solid waste, thus ensuring the integrity of the solid waste and improving the flexibility and practicality of the device during use.

[0028] Example 5 differs from Example 1 in that: like Figure 7 As shown, the support feet in the above embodiments can be replaced with casters with locking functions to improve the convenience for workers to move the device, thereby improving the flexibility of the device; there can be multiple electric push rods in the above embodiments, which are arranged in a rectangular array on the side of the top plate, and multiple electric push rods can work synchronously. When there are multiple electric push rods, the first guide rod and the first guide seat can be omitted.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
