Description
Technical Field
[0001] This utility model belongs to the field of ground cleaning, and in particular relates to an automatic wastewater collection device for garbage stations. Background Technology
[0002] When garbage trucks transport garbage to the garbage station and dump it into the compression equipment, wastewater inevitably leaks from the truck onto the ground outside the compression equipment. Furthermore, when the truck brakes and starts, wastewater drips from the gaps in the truck bed due to inertia, polluting the garbage station floor. If not cleaned promptly, this not only breeds mosquitoes and flies and emits foul odors, but may also lead to safety incidents such as people slipping and falling. Currently, most cleaning methods involve high-pressure water jets, which, while effective, can easily cause the ground to freeze in winter and waste water resources. Another method is using floor scrubbers, but some solid waste, such as plastic bags and beverage bottles, remains on the garbage station floor. If these are cleaned directly by the floor scrubber, the plastic bags can easily clog the scrubber's internal drainage pipes, requiring manual sweeping of the solid waste before scrubbing, wasting time. Therefore, garbage stations currently lack a wastewater collection device that is not limited by seasons or the type of solid waste. Summary of the Invention
[0003] The purpose of this utility model is to solve the problem that there is a lack of sewage collection devices in garbage stations that are not limited by seasons and solid waste, and to propose an automatic sewage collection device for garbage stations.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An automatic wastewater collection device for a garbage station includes a housing with openings at the bottom and left side. Two wheels are provided on each of the front and rear sides of the housing. Sealing strips are fixed to the bottom of the front and rear side walls and the right side wall of the housing, with the lower ends of the sealing strips at the same height as the four wheels.
[0006] The housing contains a solid-liquid separation unit that can push liquid on the ground to the right and lift solids on the ground upwards. A sludge suction unit is located on the right side of the solid-liquid separation unit, which can collect and store the wastewater on the right side of the solid-liquid separation unit. A storage box is located on the left side of the solid-liquid separation unit, and a lever is fixed on the right side of the storage box. The lever can transfer the solids adsorbed on the solid-liquid separation unit into the storage box.
[0007] As a further description of the above technical solution:
[0008] The solid-liquid separation unit includes a rotating shaft with its axis running in the front-to-back direction. A drum is coaxially fixed on the rotating shaft, and multiple rubber strips are fixed on the outer edge of the drum. Each rubber strip coincides with the drum's generatrix. Multiple through slots are opened on the front and rear side walls of the drum, and each through slot coincides with the radial direction of the drum. The number of through slots on the front and rear side walls of the drum is equal and aligned front to back. A square rod is provided in each pair of corresponding through slots, with the front and rear ends of the square rod located in the front and rear through slots, respectively. Multiple round rods are fixed on each square rod inside the drum, and each round rod coincides with the radial direction of the drum. A round hole is opened on the side wall of the drum, and the outer end of the round rod extends out of the drum from the round hole. The round rod outside the drum is provided with burrs. When the drum rotates counterclockwise, the rubber strips can push the sewage on the ground to the right. The solids on the ground rotate with the drum under the action of the multiple round rods squeezing and the burrs hooking.
[0009] As a further description of the above technical solution:
[0010] Each of the square rods has a round shaft fixed at both ends. A disc is coaxially fixed on the inner wall of the shell on both sides of the drum. Each disc has an annular groove on the side near the drum. Each round shaft is located in the groove. The front end of the rotating shaft extends out of the shell and is fixed with a large pulley. A motor is fixed in the shell on the upper right side of the drum. The rotating shaft of the motor extends forward out of the shell and is fixed with a small pulley. A belt is provided between the large pulley and the small pulley. When the motor drives the drum to rotate, when the outer end of the round rod is close to the ground, the round rod retracts into the drum under the guidance of the square rod and the groove. When the outer end of the round rod is close to the shift fork, the round rod extends out of the drum under the guidance of the square rod and the groove.
[0011] As a further description of the above technical solution:
[0012] The aforementioned sludge suction unit includes a rubber roller, the front and rear ends of which are fixed to two wheels on the right side, and the radius of the rubber roller is equal to the radius of the wheels. A suction pipe is provided between the rubber roller and the roller, and a sludge tank is fixed above the roller. A water pump is installed in the sludge tank, and the water pump is connected to the suction pipe through a rigid pipe. The water pump can suck the sludge between the roller and the rubber roller into the sludge tank through the pipe and the suction pipe.
[0013] As a further description of the above technical solution:
[0014] The fork includes a flat plate, with its front and rear ends fixed to the inner wall of the housing. Multiple thin rods are fixed to the right end of the plate, each with its right end bent upwards. The distance between two adjacent thin rods is greater than the diameter of the round rod. As the round rod rotates with the roller to a position close to the fork, the roller's continued rotation causes the thin rods and round rods to intersect. Further rotation causes the round rod to pass downwards between two thin rods. The right end of the fork is higher than its left end, and the left end of the fork is higher than the right side wall of the storage tank. This ensures that after the solids on the solid-liquid separation device are picked up by the fork, they can slide downwards and to the left along the fork and fall into the storage tank. The left side wall of the storage tank is higher than the right side wall to prevent the solid-liquid separation device from throwing the liquid carried on its surface forward out of the housing during rotation.
[0015] As a further description of the above technical solution:
[0016] A support plate is fixed inside the housing on the left side of the roller. A stop bar is fixed to the right end of the support plate, and the distance from the stop bar to the left side of the housing is equal to the left and right width of the storage box. A baffle is hinged to the left end of the front side wall of the housing, and a stop block is fixed to the left end of the rear side wall of the housing. When in use, the storage box is placed on the support plate, and the right side of the storage box is in contact with the stop bar. Then the baffle is rotated to contact the stop block. At this time, the storage box can be fixed by the baffle and the stop bar.
[0017] As a further description of the above technical solution:
[0018] The front end of the housing is fixed with a belt cover by bolts. The large pulley, small pulley and belt are all located inside the belt cover. A handle is fixed on the right side of the housing to facilitate the user to push the housing to move. A water outlet pipe is connected to the bottom of the sewage tank. The outer end of the water outlet pipe extends out of the housing and is fixed with a valve.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0020] (1) When the roller of this utility model is driven to rotate by the motor, the square rod set on the roller also rotates with the roller. Both ends of the square rod are engaged with the annular sliding groove, so that the round rod fixed on the square rod can automatically retract whenever it contacts the ground, and automatically extend when the round rod is close to the fork. This achieves the effect that the round rod does not interfere with the movement of the ground, and can lift the solid garbage upward. In addition, a rubber strip is fixed on the roller. While lifting the solid garbage upward, the liquid that cannot be lifted can also be pushed backward to the suction pipe to complete the purpose of solid-liquid separation and avoid the solid garbage on the ground of the garbage station from clogging the suction system.
[0021] (2) The front and rear ends of the rubber roller of this utility model are coaxially fixed with the two wheels on the right side, and the radius of the rubber roller is equal to the radius of the wheel. This allows the rubber roller to not only share the load on the wheel, avoiding the need for frequent replacement of the right wheel due to excessive load, but also achieves the effect of the rubber roller always being in contact with the ground. This allows the sewage to be squeezed to the left by the continuously rotating rubber roller, raising the sewage level between the roller and the rubber roller, making it convenient for the sewage suction pipe to suck up the sewage.
[0022] (3) When the roller of this utility model rotates, it can not only achieve the effect of solid-liquid separation, but also make the solid waste rotate with the roller during the rotation process. That is, the posture of the solid waste will change continuously. If the solid waste is a plastic bottle, the sewage inside the bottle can flow out from the bottle mouth during the rotation process. In addition, since the solid waste needs to be moved from the left side of the roller to the right side of the roller and then lifted up by the round rod, the rubber strip on the roller has a squeezing action on the solid waste. If the solid waste is a plastic bag, the rubber strip can squeeze out the sewage inside the plastic bag in combination with the piercing effect of the burrs on the round rod, so as to avoid the garbage in the storage box carrying too much sewage.

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-5 This utility model provides a technical solution for an automatic wastewater collection device for landfill sites:
[0031] An automatic wastewater collection device for a garbage station includes a housing 1, with openings at the bottom and left side of the housing 1. Two wheels 2 are provided on each of the front and rear sides of the housing 1. Sealing strips 3 are fixed to the bottom of the front and rear side walls and the right side wall of the housing 1, with the lower end of the sealing strips 3 being at the same height as the four wheels 2.
[0032] The housing 1 contains a rotating shaft 7, whose axis runs along the front-to-back direction. A roller 8 is coaxially fixed on the rotating shaft 7. Multiple rubber strips 9 are fixed on the outer edge of the roller 8, each rubber strip 9 coinciding with the generatrix of the roller 8. Multiple through slots 10 are formed on the front and rear side walls of the roller 8, each through slot 10 coinciding with the radial direction of the roller 8. The number of through slots 10 on the front and rear side walls of the roller 8 is equal and aligned front to back. A square rod 11 is provided in each pair of corresponding through slots 10, with the front and rear ends of the square rod 11 located in the front and rear through slots 10 respectively. Multiple round rods 12 are fixed on each square rod 11 inside the roller 8, each round rod 12 coinciding with the radial direction of the roller 8. A round hole is formed on the side wall of the roller 8, and the outer end of the round rod 12 extends out of the roller 8 from the round hole. The round rod 12 outside the roller 8 is provided with burrs. Round shafts 13 are fixed at both the front and rear ends of the square rod 11. On the inner walls of the shell 1 on both the front and rear sides of the roller 8, there are coaxially fixed discs 14. Each disc 14 has an annular groove 15 on the side near the roller 8. Each round shaft 13 is located in the groove 15. The front end of the rotating shaft 7 extends out of the shell 1 and is fixed with a large pulley. A motor is fixed in the shell 1 on the upper right side of the roller 8. The rotating shaft 7 of the motor extends forward out of the shell 1 and is fixed with a small pulley. A belt is provided between the large pulley and the small pulley. When the motor drives the roller 8 to rotate, when the outer end of the round rod 12 is close to the ground, the round rod 12 retracts into the roller 8 under the guidance of the square rod 11 and the groove 15. When the outer end of the round rod 12 is close to the fork 6, the round rod 12 extends out of the roller 8 under the guidance of the square rod 11 and the groove 15. At the same time, the rubber strip 9 pushes the sewage on the ground to flow to the right. The solids on the ground rotate with the roller 8 under the action of the multiple round rods 12 and the burr hook.
[0033] A rubber roller 16 is provided on the right side of the rotating shaft 7. The front and rear ends of the rubber roller 16 are fixed to the two wheels 2 on the right side, and the radius of the rubber roller 16 is equal to the radius of the wheel 2. A suction pipe 17 is provided between the rubber roller 16 and the roller 8. A sewage tank 18 is fixed above the roller 8. A water pump is provided in the sewage tank 18. The water pump is connected to the suction pipe 17 through a rigid pipe. The water pump can suck the sewage between the roller 8 and the rubber roller 16 into the sewage tank 18 through the pipe and the suction pipe 17.
[0034] A storage box 5 is located on the left side of the rotating shaft 7, and a fork 6 is fixed on the right side of the storage box 5. The fork 6 includes a flat plate 19, the front and rear ends of which are fixed to the inner wall of the housing 1. Multiple thin rods 20 are fixed to the right end of the flat plate 19. The right end of each thin rod 20 is bent upward, and the distance between two adjacent thin rods 20 is greater than the diameter of the round rod 12. After the round rod 12 rotates with the roller 8 to a position close to the fork 6, the roller 8 continues to rotate, which allows the thin rods 20 and the round rod 12 to intersect each other. As the roller 8 continues to rotate, the round rod 12 passes downward between two thin rods 20. The right end of the fork 6 is higher than the left end, and the left end of the fork 6 is higher than the right side wall of the storage box 5. This ensures that after the solid on the solid-liquid separation device is picked up by the fork 6, the solid can slide down to the left along the fork 6 and fall into the storage box 5. The left side wall of the storage box 5 is higher than the right side wall. This prevents the solid-liquid separation device from throwing the liquid carried on its surface forward out of the housing 1 when it rotates.
[0035] A support plate 21 is fixed inside the housing 1 on the left side of the roller 8. A baffle 22 is fixed to the right end of the support plate 21, and the distance from the baffle 22 to the left side of the housing 1 is equal to the left and right width of the storage box 5. A baffle 23 is hinged to the left end of the front side wall of the housing 1, and a block 24 is fixed to the left end of the rear side wall of the housing 1. When in use, the storage box 5 is placed on the support plate 21, and the right side of the storage box 5 is in contact with the baffle 22. Then the baffle 23 is rotated to contact the block 24. At this time, the storage box 5 can be fixed by the baffle 23 and the baffle 22.
[0036] The front end of the housing 1 is fixed with a belt cover 25 by bolts. The large pulley, small pulley and belt are all located inside the belt cover 25. A handle 26 is fixed on the right side of the housing 1 to facilitate the user to push the housing 1 to move. A water outlet pipe is connected to the bottom of the sewage tank 18. The outer end of the water outlet pipe extends out of the housing 1 and is fixed with a valve.
[0037] Working principle:
[0038] When using this utility model, first connect the motor and water pump to the external power supply and start them. The motor drives the drum 8 to rotate counterclockwise. Then, push the device to move it through the handle 26 to clean up solid waste and sewage on the ground.
[0039] After solid waste and sewage enter the housing 1 from the left side, the rubber strip 9 pushes the sewage to the right due to the counterclockwise rotation of the roller 8. Since the radius of the rubber roller 16 is equal to the radius of the wheel 2, and the rubber roller 16 and the wheel 2 are coaxially fixed, the rubber roller 16 also rotates counterclockwise while pushing the housing 1 to move. Therefore, the rubber roller 16 squeezes the sewage to the left. That is, the rubber strip 9 and the rubber roller 16 gather the sewage between the roller 8 and the rubber roller 16, raising the sewage level between the roller 8 and the rubber roller 16, making it easier for the suction pipe 17 to collect the sewage. Even if there are gaps between the front and rear ends of the rubber roller 16 and the inner wall of the housing 1, causing a small amount of sewage to flow to the right side of the rubber roller 16, it can be gathered under the housing 1 by the sealing strip 3 fixed to the bottom of the front and rear side walls and the right side wall of the housing 1, avoiding the presence of sewage residue on the cleaned ground. After cleaning, the housing 1 is moved to the designated position, and the sewage on the right side of the rubber roller 16 is cleaned separately.
[0040] As the roller 8 pushes the sewage to the right, if there is solid waste such as plastic bags or plastic bottles on the ground, the outer end of the round rod 12 will insert into the solid waste as the roller 8 rotates, or the solid waste will be stuck between two round rods 12. The roller 8 continues to rotate, and the round rod 12 carries the solid waste through from under the roller 8 and moves it to the position of the fork 6. Since the distance between the two adjacent thin rods 20 on the fork 6 is greater than the diameter of the round rod 12, the thin rods 20 will remove the waste carried on the round rod 12 during the continuous rotation of the round rod 12 and drop it into the storage box 5. In addition, since the solid waste is flipped at least 180° during the rotation of the roller 8, if there is liquid in the plastic bag or plastic bottle, it will also flow out during the flipping process, so as to avoid the waste in the storage box 5 being too heavy to be easily dumped.
[0041] After cleaning, rotate the baffle 23 forward to remove the storage box 5, pour the garbage in the storage box 5 into the compression device, move the device to a suitable position, and open the valve on the water outlet pipe to discharge the sewage in the sewage tank 18.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present utility model within the scope of the technology disclosed in the present utility model, and all such substitutions or changes should be included within the protection scope of the present utility model.
