Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to an environmentally friendly solid-liquid separation device for waste. Background Technology

[0002] To address the inconvenience and potential clogging issues associated with directly discharging water-containing waste into sewers, existing technologies such as patent publication number CN209333316U (which discloses a solid-liquid separation device for a sweeper truck, including a dumping tank, a filter screen, and an lifting auger); patent publication number CN209739906U (which discloses a solid-liquid separation device for a waste collection truck, including a solid-liquid separation tank and a solid waste collection tank); and patent publication number CN110328888B (which discloses an industrial waste compression treatment device, including a compression tank, water permeable holes, a V-shaped plate, a liquid tank, left and right baffles, a water outlet, a gate-shaped bracket, and a pressure plate) can all perform solid-liquid separation treatment of water-containing waste, improving waste treatment efficiency.

[0003] In the process of realizing this invention, the inventors discovered the following problems in the prior art:

[0004] Existing technologies treat water-containing waste through a separate solid-liquid separation device, which requires a fixed location or a separate vehicle, making it impossible to install on a garbage sweeper. Furthermore, it requires manual labor to put the waste into the solid-liquid separation device, increasing the input of manpower and time and reducing operational efficiency. Summary of the Invention

[0005] Therefore, there is a need to provide a solid-liquid separation device for garbage sweepers to solve the technical problems of existing technologies that use a separate solid-liquid separation device to process water-containing garbage. This requires a fixed location or a separate vehicle that cannot be installed on the garbage sweeper, and also requires manual loading of garbage into the solid-liquid separation device, which increases manpower and time input and reduces operational efficiency.

[0006] To achieve the above objectives, the inventors provide a solid-liquid separation device for garbage sweepers, comprising:

[0007] A dust collection device, comprising a suction pipe, an exhaust pipe, a filter screen, an exhaust fan, a garbage drop pipe, and a garbage drop outlet, wherein the filter screen is disposed in the exhaust pipe, the exhaust fan is disposed at the end of the exhaust pipe, the garbage drop pipe is connected to the suction pipe, and the garbage drop outlet is connected to the garbage drop pipe, the dust collection device being used to collect road garbage;

[0008] A compression device is provided, which is connected to the vacuuming device via a waste discharge port. The compression device includes a waste inlet, a housing, a main hydraulic cylinder, a push plate, a water outlet, a water tank, support legs, a rotating door, a rear hydraulic cylinder, a dry waste discharge port, and a water filter hole. The waste inlet is connected to the waste discharge port. The main hydraulic cylinder is located inside the housing. The push plate is connected to the main hydraulic cylinder. The water outlet is located on the housing. The water tank is connected to the water outlet. The support legs are connected to the water tank. The rotating door is located inside the housing. The rear hydraulic cylinder connects the rotating door to the housing. The water filter hole is located on the push plate. The compression device is used to compress the water-containing waste collected inside the vacuuming device.

[0009] A waste transfer device is connected to a compression device via a dry waste discharge port. The waste transfer device includes a motor, motor support feet, a first gear, a second gear, a transfer device housing, a main shaft, a screw feeder, and a waste outlet. The motor support feet are mounted on the motor. The first gear is connected to the motor, and the second gear is connected to the first gear. The transfer device support feet are mounted on the transfer device housing. The main shaft is connected to the second gear. The screw feeder is mounted on the main shaft, and the waste outlet is located on the transfer device housing. The waste transfer device is used to transfer the dry waste compressed by the compression device.

[0010] A waste storage device is connected to a waste transfer device via a waste outlet. The waste storage device includes a threaded port, a storage device housing, a first tension spring, and a second tension spring. The threaded port is located on the storage device housing and connected to the waste outlet. The first tension spring is located on the storage device housing, and the second tension spring is located on the storage device housing. The waste storage device is used to store dry waste.

[0011] Unlike existing technologies, the above-mentioned technical solution can separate solid and liquid waste while ensuring the normal operation of the vehicle, reducing the number of times to go to the waste treatment station to empty the waste, and improving work efficiency and mileage; the liquid waste after solid-liquid separation can be directly discharged into the sewer without the risk of blockage, and the solid waste is stored in the waste storage device, which can be directly replaced, which is convenient and quick and does not require frequent cleaning; the device is integrated into the sweeper, without the need for other vehicles to follow, reducing the need for personnel.

[0012] As one embodiment of the present invention, the solid-liquid separation device for the garbage sweeper is characterized in that the suction pipe is connected to the suction port at the bottom of the garbage sweeper.

[0013] Thus, by installing this device in a garbage sweeper, the garbage sucked in from the suction port at the bottom of the garbage sweeper can be directly subjected to solid-liquid separation, which is highly efficient and eliminates the need for manual garbage loading.

[0014] In one embodiment of the present invention, the exhaust fan is connected to the air outlet of the garbage sweeper, and different models can be replaced according to different vehicle models.

[0015] In this way, by replacing different models of exhaust fans, the device can be adapted to different garbage sweepers, thus increasing its applicability.

[0016] In one embodiment of the present invention, the rotating door is equipped with a pressure sensor, that is, after the pressure reaches a certain value, the hydraulic cylinder will open the rotating door.

[0017] Thus, by detecting the pressure value through the pressure sensor, when the pressure reaches a certain value, it means that the moisture in the water-containing waste has been fully discharged, and the rotating door can be opened to discharge the dry waste.

[0018] As one embodiment of the present invention, the solid-liquid separation device for the garbage sweeper also includes a control unit, which is equipped with one or more of the following modules: an overpressure alarm and protection module, a low oil level alarm module, an oil cylinder obstruction alarm module, and a compression and pressure holding time setting module.

[0019] In this way, by monitoring the operating status in real time through the control unit, an alarm signal can be issued in a timely manner when the device malfunctions or its operation is obstructed, thereby improving the safety factor.

[0042] Existing technologies treat water-containing waste through a separate solid-liquid separation device, which requires a fixed location or a separate vehicle, making it impossible to install on a garbage sweeper. Furthermore, it requires manual labor to put the waste into the solid-liquid separation device, increasing the input of manpower and time and reducing operational efficiency.

[0043] The solid-liquid separation device for garbage sweepers described in this embodiment can be applied to various application scenarios of garbage sweepers.

[0044] According to some embodiments of this application, please refer to Figures 1 to 5 This embodiment relates to a solid-liquid separation device for a garbage sweeper, including a dust suction device 1, a compression device 2, a garbage transfer device 3, and a garbage storage device 4. The dust suction device 1 is used to absorb road garbage; the compression device 2 is connected to the dust suction device 1 and is used to compress the water-containing garbage sucked in by the dust suction device 1; the garbage transfer device 3 is connected to the compression device 2 and is used to transfer the compressed, dry garbage; the garbage storage device 4 is connected to the garbage transfer device 3 through a threaded port and is used to store the compressed, dry garbage.

[0045] The vacuuming device 1 includes a vacuuming pipe 11, an exhaust pipe 12, a filter screen 13, an exhaust fan 14, a garbage drop pipe 15, and a garbage drop outlet 16. The filter screen 13 is installed in the exhaust pipe 12, the exhaust fan 14 is installed at the end of the exhaust pipe 12, the garbage drop pipe 15 is connected to the vacuuming pipe 11, and the garbage drop outlet 16 is connected to the garbage drop pipe 15.

[0046] The exhaust fan 14 creates a negative pressure in the suction pipe 11, drawing in water-containing garbage from the ground. This garbage, under the combined force of gravity and airflow, reaches the garbage discharge port 16. Because the space here is larger and the airflow speed decreases, the water-containing garbage cannot be sucked up and falls to the compression device 2 under gravity. The filter 13 also ensures that all garbage falls successfully. This avoids the problem of traditional garbage trucks filling their rear compartment with water-containing garbage, saving cleaning time.

[0047] In this embodiment, the suction pipe 11 is connected to the suction port at the bottom of the garbage sweeper, and the suction pipe directly performs solid-liquid separation treatment on the water-containing garbage sucked in from the road.

[0048] According to some embodiments of this application, optionally, the exhaust fan 14 is connected to the air outlet of the garbage sweeper, and different models can be replaced according to different vehicle models.

[0049] The compression device 2 includes a waste inlet 21, a housing 22, a main hydraulic cylinder 23, a push plate 24, a water outlet 25, a water tank 26, support legs 27, a rotating door 28, a rear hydraulic cylinder 29, a dry waste discharge port 210, and a filter hole 211. The waste inlet 21 is connected to the waste discharge port 16. The main hydraulic cylinder 23 is located inside the housing 22, and the push plate 24 is connected to the main hydraulic cylinder 23. The water outlet 25 is located on the housing 22, and the water tank 26 is connected to the water outlet 25. The support legs 27 are connected to the water tank 26. The rotating door 28 is located inside the housing 22, and the rear hydraulic cylinder 29 connects the rotating door 28 to the housing 22. The filter hole 211 is located on the push plate 24. Figure 3 As shown, the compression device 2 is used to compress the water-containing garbage collected in the vacuum cleaner 1.

[0050] With the built-in sensor, the garbage starts to be compressed when it reaches a certain volume. During the compression process, the upper part of the push plate 24 can block the garbage inlet 21 to prevent the garbage from falling further. After the compression is completed, the push plate 24 can be pushed back to allow the garbage to fall again, thus achieving continuous garbage compression.

[0051] According to some embodiments of this application, optionally, the rotating door 28 is equipped with a pressure sensor. That is, after the pressure reaches a certain value, the hydraulic cylinder 29 is activated to open the rotating door 28. When the pressure reaches a certain value, it means that the moisture in the water-containing waste has been fully discharged, and the rotating door can be opened to discharge the dry waste.

[0052] The waste transfer device 3 includes a motor 31, a motor support foot 32, a first gear 33, a second gear 34, a transfer device housing 35, a transfer device support foot 36, a main shaft 37, a screw feeding device 38, and a waste outlet 39. The motor support foot 32 is mounted on the motor 31. The first gear 33 is connected to the motor 31, and the second gear 34 is connected to the first gear 33. The transfer device support foot 36 is mounted on the transfer device housing 35. The main shaft 37 is connected to the second gear 34. The screw feeding device 38 is mounted on the main shaft 37. The waste outlet 39 is mounted on the transfer device housing 35. The waste transfer device 3 is used to transfer the dry waste compressed by the compression device 2.

[0053] By utilizing the continuous operation of the screw, waste is continuously delivered to the waste storage device 4, keeping the waste in a compressed state, reducing its volume, and increasing the single-time waste storage capacity.

[0054] The waste storage device 4 includes a threaded opening 41, a storage device housing 42, a first tension spring 43, and a second tension spring 44. The threaded opening 41 is disposed on the storage device housing 42 and connected to the waste outlet 39. The first tension spring 43 is disposed on the storage device housing 42, and the second tension spring 44 is disposed on the storage device housing 42, forming a left-right position with the first tension spring 43 to maintain tension balance. The waste storage device 4 is used to store dry waste.

[0055] The first tension spring 43 and the second tension spring 44 continuously provide tension to keep the dry waste in a compressed state. When it is fully loaded, the inlet is closed, and the waste storage device 4 can be removed and replaced with a new device through the threaded port 41. This is convenient, quick and saves time.

[0056] According to some embodiments of this application, optionally, a control unit is also included, which is provided with one or more of the following: an overpressure alarm and protection module, a low oil level alarm module, a cylinder operation obstruction alarm module, and a compression and holding time setting module.

[0057] In this way, by monitoring the operating status in real time through the control unit, an alarm signal can be issued in a timely manner when the device malfunctions or its operation is obstructed, thereby improving the safety factor.

[0058] Unlike existing technologies, the above-mentioned technical solution can separate solid and liquid waste while ensuring the normal operation of the vehicle, reducing the number of times to go to the waste treatment station to empty the waste, and improving work efficiency and mileage; the liquid waste after solid-liquid separation can be directly discharged into the sewer without the risk of blockage, and the solid waste is stored in the waste storage device 4, which can be directly replaced, which is convenient and quick and does not require frequent cleaning; the device is integrated into the sweeper, which does not require other vehicles to follow, reducing the need for personnel.

[0059] Based on the above embodiments, the specific working principle is as follows:

[0060] When the machine starts working, the exhaust fan 14 is activated, expelling air outwards. The suction pipe 11, exhaust pipe 12, and garbage drop pipe 15 are under negative pressure, drawing water-containing garbage from the ground through the suction pipe 11 and through the garbage drop pipe 15 to the garbage drop outlet 16. Air passes through the filter screen 13 and is discharged from the exhaust pipe 12. The water-containing garbage cannot pass through the filter screen 13 and thus falls from the garbage drop outlet 16 to the compression device 2. When the garbage has reached a certain volume, the main hydraulic cylinder 23 is activated, driving the push plate 24 to compress the garbage. During the compression process, the push plate can prevent the garbage from falling further from the garbage inlet 21, while the squeezed-out liquid flows from the water filter holes 211 on the push plate 24 to the water outlet 25 and is finally stored in the water tank 26. After the waste compression is completed, the rear hydraulic cylinder 29 is activated, opening the rotating door 28 to allow the dry waste to fall into the dry waste drop outlet 210. Next, the rear hydraulic cylinder 29 closes the rotating door 28, and the main hydraulic cylinder 23 drives the push plate 24 to retract, no longer obstructing the waste from falling from the waste inlet 21. Once the waste has reached a certain volume, the next waste compression can begin, thus achieving uninterrupted waste compression. When the waste falls into the waste transfer device 3, the motor 31 drives the main shaft 37 to rotate via the first gear 33 and the second gear 34, which in turn causes the screw feeder 38 mounted on the main shaft 37 to rotate, conveying the dry waste from the waste outlet 39 to the waste storage device 4. Pressure is provided by the first tension spring 43 and the second tension spring to maintain the dry waste in a compressed state. When the waste storage device is full, it can be disassembled and replaced with a new storage device for continuous operation.

[0061] In this embodiment, the power mechanism or power unit includes, but is not limited to, engines, motors, pneumatic tools, hydraulic pumps, etc. The power unit also includes direct power sources and indirect power sources. Direct power sources are those that can provide their own power, such as engines and motors, while indirect power sources include cylinders and hydraulic cylinders. The power mechanism or power unit can drive the linear reciprocating motion of the actuator through gear and rack engagement, slider and groove engagement, lead screw and nut engagement, etc.

[0062] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of the present invention, or equivalent structural or procedural transformations made using the content of the present invention's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection of the present invention.
