Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a waste storage pretreatment device. Background Technology
[0002] With the acceleration of urbanization, traditional landfill and extensive incineration have exposed many problems, such as leachate pollution of groundwater, emission of harmful gases, and low calorific value utilization. In order to solve these problems, existing technologies usually pre-treat the waste before incineration. However, existing waste incineration storage devices have the following problems: First, existing waste storage devices usually mix various types of waste together in a crude manner. The leachate from the waste is mixed together, which increases the cost and difficulty of subsequent leachate treatment. Second, since waste needs to be dehydrated and fermented before incineration, different types of waste require different fermentation times. Existing waste pre-treatment devices usually cannot store waste according to the fermentation time, resulting in poor waste incineration efficiency. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a waste storage pretreatment device that can improve waste incineration efficiency and reduce the difficulty of treating waste leachate.
[0004] The technical solution of this utility model: A waste storage pretreatment device, comprising a base, a waste storage device connected to the base, a leachate collection device connected to the base, and a controller. The waste storage device includes a feeding hopper connected to the base, several feeding pipes connected to the feeding hopper, and several storage hoppers connected to the feeding pipes. The feeding hopper is divided into several feeding channels by partitions. The feeding pipes include a first feeding pipe, a second feeding pipe connected to the first feeding pipe, and an electric dispensing valve connected to the second feeding pipe. One end of the first feeding pipe is connected to the feeding channel, and one end of the second feeding pipe is connected to the storage hopper. A hinge base and a hinge are fixedly connected to the inner wall of the first feeding pipe. The system comprises a filter plate connected to a hinge base, a rotary motor for driving the filter plate to rotate, a support plate slidably connected to a first feed pipe, and a first hydraulic cylinder for driving the support plate to move horizontally. The first feed pipe has a sliding groove, and the support plate is slidably connected to the sliding groove. When the filter plate is in a horizontal state, the support plate is located below the filter plate and in contact with the filter plate. The filter plate has a plurality of filter holes. The leachate collection device includes a connecting pipe connected to the first feed pipe, a liquid pump connected to the connecting pipe, and a leachate collection tank connected to the liquid pump. The connecting pipe is connected between the filter plate and an electric dispensing valve. The controller is electrically connected to the liquid pump, the electric dispensing valve, the first hydraulic cylinder, and the rotary motor, respectively.
[0005] Using the above technical solution, when garbage needs to be stored, firstly, the garbage is put into the corresponding feeding channel according to its type. The garbage enters the first feeding pipe through the feeding channel. At this time, the controller controls the electric dispensing valve to be in the closed state. At the same time, the controller controls the rotary motor to drive the filter plate to rotate a certain angle, and controls the first hydraulic cylinder to drive the support plate to slide a certain distance in the horizontal direction, so that the filter plate is perpendicular to the axial direction of the first feeding pipe, and the support plate is located below the filter plate and fits against it. The support plate provides support for the filter plate, and the filter plate can prevent the garbage from sliding into the second feeding pipe. Since the filter plate has several filter holes, the leachate in the garbage will flow into the first feeding pipe through the filter holes. The space between the filter plate and the electric dispensing valve is filled with leachate. The controller then controls the pump to provide suction to the connecting pipe, drawing the leachate into the leachate collection tank. This allows for the rapid collection of different types of leachate in the early stages, avoiding the mixing of leachate compared to traditional waste storage devices, thus reducing the difficulty and cost of leachate treatment. After the leachate treatment is completed, the controller opens the electric dispensing valve, and the rotary motor rotates the filter plate at a certain angle, so that the filter plate no longer obstructs the passage of waste through the first feed pipe. The waste slides from the first feed pipe through the second feed pipe and finally enters the storage bin, completing the waste storage process.
[0006] A further feature of this invention includes a leachate squeezing device, comprising a fixed base fixedly connected to the equipment base, a second hydraulic cylinder fixedly connected to the fixed base, a third hydraulic cylinder fixedly connected to the fixed base, a first connecting rod connected to the second hydraulic cylinder, a second connecting rod connected to the third hydraulic cylinder, a first squeezing plate connected to the first connecting rod, and a second squeezing plate connected to the second connecting rod. The first feed pipe is provided with a first through hole and a second through hole, and the first connecting rod and the second connecting rod are slidably connected to the first through hole and the second through hole, respectively. The first connecting rod and the second connecting rod are located on the left and right sides of the first feed pipe, respectively. The number of leachate squeezing devices is the same as the number of first feed pipes. The controller is electrically connected to the second hydraulic cylinder and the third hydraulic cylinder, respectively. Using the above technical solution, when the waste is blocked by the filter plate, the controller controls the second and third hydraulic cylinders to drive the first and second connecting rods to move in opposite directions, thereby driving the first and second extrusion plates to move in opposite directions, thus completing the extrusion of the waste above the filter plate. This can further improve the efficiency of leachate outflow from the waste, thereby reducing the leachate content of the waste and helping to improve the subsequent incineration efficiency.
[0007] Further features of this invention: the storage compartment is provided with several fixing slots, and several partition plates are stacked on the equipment base. The partition plates are T-shaped, the upper half of the partition plates is adapted to the shape and size of the fixing slots, and the lower half of the partition plates is adapted to the cross-sectional shape and size of the storage compartment.
[0008] Using the above technical solution, when the work is finished each day, the partition plate is inserted into the fixed groove. Since the upper part of the partition plate is compatible with the shape and size of the fixed groove, and the lower part of the partition plate is compatible with the cross-sectional shape and size of the storage bin, date labels can be affixed to the partition plate to further categorize the waste according to time. The fermentation time of the waste can be reasonably arranged according to the characteristics of the waste, thereby further improving the efficiency of subsequent waste incineration.
[0009] A further feature of this invention is that the partition plate is also provided with a connecting plate fixedly connected to the partition plate, the connecting plate being perpendicular to the partition plate, and the thickness of the connecting plate being less than 2 cm.
[0010] By adopting the above technical solution, since the partition plate is also provided with a connecting plate that is fixedly connected to the partition plate, and the thickness of the connecting plate is less than 2 cm, when the partition plate is needed, the connecting plate can be inserted into the bottom of the waste, and the weight of the waste itself can press down on the connecting plate, thereby ensuring the positional stability of the partition plate, and thus ensuring that the waste can be classified according to the time it has been in the storage bin, thereby improving the efficiency of subsequent waste incineration.

Detailed Implementation
[0014] like Figure 1-2 As shown, a waste storage pretreatment device includes a base 1, a waste storage device 2 connected to the base 1, a leachate collection device 3 connected to the base 1, and a controller 4. The waste storage device 2 includes a feed hopper 5 connected to the base 1, several feed pipes 6 connected to the feed hopper 5, and several storage hoppers 7 connected to the feed pipes 6. The feed hopper 5 is divided into several feed channels 8 by partitions. The feed pipes 6 include a first feed pipe 9, a second feed pipe 10 connected to the first feed pipe 9, and an electric feed valve 11 connected to the second feed pipe 10. One end of the first feed pipe 9 is connected to the feed channel 8, and one end of the second feed pipe 10 is connected to the storage hopper 7. The first feed pipe 9 is provided with a hinge base 12 fixedly connected to the inner wall of the first feed pipe 9, a filter plate 13 hinged to the hinge base 12, and a filter plate 13. The device includes a rotary motor 14 that drives the filter plate 13 to rotate, a support plate 15 that is slidably connected to the first feed pipe 9, and a first hydraulic cylinder 16 that drives the support plate 15 to move horizontally. The first feed pipe 9 is provided with a sliding groove 17, and the support plate 15 is slidably connected to the sliding groove 17. When the filter plate 13 is in a horizontal state, the support plate 15 is located below the filter plate 13 and is in contact with the filter plate 13. The filter plate 13 is provided with a plurality of filter holes 18. The leachate collection device 3 includes a connecting pipe 19 connected to the first feed pipe 9, a liquid pump 20 connected to the connecting pipe 19, and a leachate collection tank 21 connected to the liquid pump 20. The connecting pipe 19 is connected between the filter plate 13 and the electric dispensing valve 11. The controller 4 is electrically connected to the liquid pump 20, the electric dispensing valve 11, the first hydraulic cylinder 16, and the rotary motor 14, respectively.
[0015] When garbage needs to be stored, firstly, the garbage is put into the corresponding feeding channel 8 according to its type. The garbage enters the first feeding pipe 9 through the feeding channel 8. At this time, the controller 4 controls the electric dispensing valve 11 to be in the closed state. At the same time, the controller 4 controls the rotary motor 14 to drive the filter plate 13 to rotate a certain angle, and controls the first hydraulic cylinder 16 to drive the support plate 15 to slide a certain distance in the horizontal direction, so that the filter plate 13 is perpendicular to the axial direction of the first feeding pipe 9, and the support plate 15 is located below the filter plate 13 and fits against it. The support plate 15 provides support for the filter plate 13. The filter plate 13 can prevent the garbage from sliding into the second feeding pipe 10. Since the filter plate 13 is provided with several filter holes 18, the leachate in the garbage will flow into the first feeding pipe through the filter holes 18. The leachate is drawn into the leachate collection tank 21 by the leachate pump 20 controlled by the controller 4 to provide suction to the connecting pipe 19. This allows for the rapid collection of different types of leachate in the early stages, avoiding the mixing of leachate compared to traditional waste storage devices 2, thus reducing the difficulty and cost of leachate treatment. After the leachate treatment is completed, the controller controls the electric dispensing valve 11 to be open. At the same time, the rotary motor 14 drives the filter plate 13 to rotate at a certain angle, so that the filter plate 13 no longer blocks the waste from passing through the first feed pipe 9. The waste slides from the first feed pipe 9 through the second feed pipe 10 and finally enters the storage bin 7, completing the waste storage work.
[0016] It also includes a leachate squeezing device 22, which includes a fixed base 23 fixedly connected to the equipment base 1, a second hydraulic cylinder 24 fixedly connected to the fixed base 23, a third hydraulic cylinder 25 fixedly connected to the fixed base 23, a first connecting rod 26 connected to the second hydraulic cylinder 24, a second connecting rod 27 connected to the third hydraulic cylinder 25, a first squeezing plate 28 connected to the first connecting rod 26, and a second squeezing plate 29 connected to the second connecting rod 27. The first feed pipe 9 is provided with a first through hole 30 and a second through hole 31, respectively. The first connecting rod 26 and the second connecting rod 27 are slidably connected to the first through hole 30 and the second through hole 31, respectively. The first connecting rod 26 and the second connecting rod 27 are located on the left and right sides of the first feed pipe 9, respectively. The number of leachate squeezing devices 22 is the same as the number of first feed pipes 9. The controller 4 is electrically connected to the second hydraulic cylinder 24 and the third hydraulic cylinder 25, respectively.
[0017] When waste is blocked by filter plate 13, controller 4 controls the second hydraulic cylinder 24 and the third hydraulic cylinder 25 to drive the first connecting rod 26 and the second connecting rod 27 to move in opposite directions, thereby driving the first extrusion plate 28 and the second extrusion plate 29 to move in opposite directions, thus completing the extrusion of waste above filter plate 13. This can further improve the efficiency of leachate outflow from waste, thereby reducing the leachate content of waste and helping to improve subsequent incineration efficiency. The storage bin 7 is provided with several fixed slots 32, and several partition plates 33 are stacked on the equipment base 1. The partition plates 33 are T-shaped, the upper half of the partition plate 33 is adapted to the shape and size of the fixed slots 32, and the lower half of the partition plate 33 is adapted to the cross-sectional shape and size of the storage bin.
[0018] At the end of each workday, the partition plate 33 is inserted into the fixing slot 32. Since the upper part of the partition plate 33 is compatible with the shape and size of the fixing slot 32, and the lower part of the partition plate 33 is compatible with the cross-sectional shape and size of the storage bin 7, date labels can be affixed to the partition plate 33 to further categorize the waste according to time, and the fermentation time of the waste can be reasonably arranged according to the characteristics of the waste, thereby further improving the efficiency of subsequent waste incineration.
[0019] The partition plate 33 is also provided with a connecting plate 34 fixedly connected to it. The connecting plate 34 is perpendicular to the partition plate 33 and its thickness is less than 2 cm. Since the partition plate 33 is also provided with a connecting plate 34 fixedly connected to it, and the thickness of the connecting plate 34 is less than 2 cm, when the partition plate 33 needs to be used, the connecting plate 34 can be inserted into the bottom of the waste. The weight of the waste itself presses down on the connecting plate 34, thereby ensuring the positional stability of the partition plate 33. This ensures that the waste can be classified according to the time elapsed since entering the storage bin 7, thus improving the subsequent waste incineration efficiency.
