Description

Domestic garbage loading method and loading system Technical Field

[0001] The present invention relates to the technical field of domestic waste transportation, and in particular to a domestic waste loading device. Background Art

[0002] At present, after domestic waste is collected through various methods and enters the transfer site (this stage of domestic waste collection and transportation is often called front-end domestic waste collection), the domestic waste must be compressed and then transported to the treatment site.

[0003] The main purpose of compressing domestic waste is to remove moisture from it. If the wastewater is not compressed, it will seep into the soil and groundwater after landfill, causing soil and groundwater pollution and seriously harming the ecological environment. Although technological advances have gradually replaced landfill as the primary method of domestic waste treatment, the traditional method of compressing domestic waste before transporting it to large domestic waste dumps has not changed.

[0004] There are three technical solutions for domestic waste transfer sites: horizontal compression loading (horizontal), flip vertical loading (vertical), and vehicle-to-vehicle docking compression loading. All three solutions have technical problems:

[0005] The first method is horizontal compression loading. A garbage storage trough is set up at the transfer site, and a pressure plate is set up inside the trough. The front-end domestic garbage collection truck dumps the collected garbage into the trough and then squeezes the garbage into the cargo box through the pressure plate. After loading, the cargo box is lifted and dragged horizontally onto the chassis of the transport vehicle for transportation. The technical problems are:

[0006] 1) The pressure plate mechanism is susceptible to damage. Domestic waste is a complex mix, often containing stones, tiles, and even rebar. These hard objects can easily cause jamming, corrosion, and other damage to the moving parts of the pressure plate mechanism. Furthermore, the large amount of waste stored in the hopper requires the pressure plate to shear some of the waste to compress it, a process that can easily damage the pressure plate. If the pressure plate mechanism is damaged, the waste transfer line cannot load trucks.

[0007] Second, the compressed wastewater is leachate, which can seriously pollute the environment. Furthermore, the serious environmental pollution caused by compressed wastewater also makes it difficult to locate waste transfer stations.

[0008] 3) Hook-arm waste transport, used in conjunction with compression, carries a high level of dead weight and a low payload. The hook-arm loading system of a hook-arm transporter is a laborious lever, requiring the chassis to add the dead weight of the hook arm. To accommodate this dead weight, the waste container used with the hook-arm transporter must be strengthened, further increasing its dead weight. This added dead weight reduces the payload. Furthermore, after loading, the container must be lifted and dragged horizontally onto the transport vehicle's chassis for transport. This lifting and dragging process increases safety risks. To mitigate these risks, load weights are limited, significantly reducing the payload.

[0009] 4) The horizontal compression loading trough is very deep. To accommodate the compression platen's ability to squeeze the garbage into the cargo box, the trough is very deep, typically no less than 6 meters. When the front-end domestic waste collection truck dumps the garbage into the trough, it generates backflow (odorous airflow). The deep trough creates a large backflow, making it difficult to collect and treat odors.

[0010] The second method is vertical loading, which uses hooks, wire ropes, and pallets to flip the container from a horizontal position to a vertical position, and then loads the container onto the vehicle using gravity. After loading, the container is flipped from a vertical position to a horizontal position using hooks, wire ropes, and pallets, and then placed on the chassis of the transport vehicle for transportation. The technical problems are:

[0011] The hook arm, wire rope, and pallet used with the vertical loading method result in a high level of dead weight and low payload. The "flipping" process, in particular, increases safety risks, and to mitigate these risks, load weights are limited, significantly reducing payload.

[0012] Second, the cargo box of a vertically tilted loading truck is very deep. To accommodate more garbage, the cargo box of a vertically tilted loading truck is very long, generally at least 7 meters. This "deep" cargo box is a sign of the truck being tilted. When garbage collection trucks dump garbage at the transfer site, they generate backflow (odorous airflow). The deep cargo box creates a large backflow, making it difficult to collect and treat odors.

[0013] The third type is vehicle-to-vehicle docking and compression loading. The front-end domestic waste collection vehicle docks with the compression waste transport vehicle, and the front-end domestic waste collection vehicle dumps the waste into the dump bucket of the compression waste transport vehicle in multiple batches. The dump bucket is lifted and turned to dump the waste into the compression chamber of the compression waste transport vehicle. The vehicle-mounted pressure plate squeezes the waste into the cargo box, and after loading, it is transported by the compression waste transport vehicle. The technical problems are:

[0014] Loading efficiency is low. The loading process of truck-to-truck docking and compression loading is complex, and each reciprocating loading process can only carry a small amount of garbage. (The vertical loading method uses the front-end domestic waste collection truck to dump the entire truck to complete the loading process.) Transfer stations generally handle large amounts of garbage, making the process inefficient and impractical.

[0015] Enclosed loading is impossible. The truck-to-truck docking and compression loading process requires lifting and flipping the bucket, requiring a wide range of movement. Furthermore, the variety of styles and models of waste collection trucks at the front end makes this method of enclosed loading extremely expensive, or even impossible. Without enclosed loading, garbage and sewage can leak, and odors can escape, causing environmental pollution. While this loading method can carry a large payload, it has been widely abandoned due to environmental concerns. Technical issues

[0016] The purpose of the present invention is to provide a method and system for loading domestic waste to solve the problems that domestic waste needs to be compressed before loading, the technical problem of sewage and odor polluting the environment during loading, and the technical problem of poor economic benefits in transporting domestic waste. Technical Solutions

[0018] 1) The garbage truck drives to the bottom of the garbage loading hopper of the garbage transfer workshop;

[0019] 2) When the cargo box of the garbage truck is in a horizontal state, remove the cargo box cover to fully open the cargo box of the garbage truck;

[0020] 3) controlling the telescopic sealing structure to extend downward to the cargo box opening of the garbage truck, thereby forming a rectangular annular seal between the cargo box opening of the garbage truck and the garbage loading hopper; the telescopic sealing structure is arranged outside the garbage loading hopper;

[0022] 5) Control the telescopic sealing structure on the outside of the garbage loading hopper to retract and reset upwards;

[0023] 6) Close the cargo box cover of the garbage truck.

[0024] Furthermore, the method for loading domestic waste also includes closing the lower end outlet of the telescopic sealing structure with a sealing plate after step 6), or moving the cargo box of another garbage transport truck below the outlet of the telescopic sealing structure after step 6) to form a rectangular annular seal.

[0025] Furthermore, the domestic waste loading method also includes extracting and deodorizing the gas in the rectangular annular sealed space.

[0026] The present invention also discloses a domestic waste loading system for implementing the above-mentioned domestic waste loading method, including a garbage loading funnel for introducing garbage into the cargo box of a garbage transport truck, a telescopic sealing structure arranged outside the garbage loading funnel for forming a rectangular annular seal between the cargo box opening and the garbage loading funnel outlet, and a box cover picking and placing device for picking up and placing the garbage transport truck cargo box cover.

[0027] Furthermore, the domestic waste loading system also includes a suspension fixedly arranged outside the telescopic sealing structure, two sealing plates arranged on the suspension for sealing the lower port of the telescopic sealing structure, and a driving device for driving the two sealing plates to perform separation and combination movements.

[0028] Furthermore, the driving device includes a rack arranged on the sealing plate, a gear matched with the rack, and a motor arranged on the suspension to drive the gear to rotate.

[0029] Furthermore, the telescopic sealing structure includes a fixed sealing sleeve arranged outside the garbage loading funnel, a movable sealing sleeve that slides up and down with the fixed sealing sleeve, and a first linear motion driver for driving the movable sealing sleeve to move up and down.

[0030] Furthermore, the first linear motion driver is arranged vertically, and the lower end of the first linear motion driver is fixedly arranged, and a supporting block that cooperates with the upper end of the first linear motion driver is provided on the movable sealing sleeve.

[0031] Furthermore, the telescopic sealing structure also includes a rubber sealing skirt arranged at the lower end of the movable sealing sleeve.

[0032] Furthermore, the suspension is a rectangular sealed tube.

[0033] Furthermore, the box cover picking and placing device includes a hydraulic cylinder with a telescopic rod pointing vertically downward, a horizontal fork plate or a movable connecting piece connected to the piston rod of the hydraulic cylinder, and a second linear motion driver for driving the hydraulic cylinder to move horizontally.

[0034] Furthermore, the domestic waste loading system also includes a parking positioning device for the garbage transport truck.

[0035] Furthermore, the parking positioning device includes a guide limit track for guiding the garbage transport truck to travel under the garbage loading funnel and a parking distance positioning plate for cooperating with a ranging radar arranged at the front of the garbage transport truck.

[0036] Furthermore, the domestic waste loading system also includes a combustion and deodorization device, which includes a gas drainage pipe connected to the space inside the fixed sealing sleeve, a combustion furnace connected to the gas drainage pipe, a vertical combustion chamber connected to the combustion furnace, an exhaust pipe connected to the exhaust port of the vertical combustion chamber, an exhaust fan arranged at the end of the exhaust pipe, and a cooling device arranged outside the vertical combustion chamber and the exhaust pipe.

[0037] Furthermore, the cooling device includes a cooling water tank arranged outside the vertical combustion chamber and the exhaust pipe, and a cooling water pipe wrapped outside the vertical combustion chamber. Beneficial effects

[0038] 1. In the method and system for loading domestic waste of the present invention, the movable sealing sleeve of the telescopic sealing structure can move up and down to fit tightly with the cargo box opening of the garbage truck, thereby forming a rectangular ring-shaped seal between the cargo box opening of the garbage truck and the garbage loading funnel; the front-end domestic waste collection truck loads the collected domestic waste into the cargo box of the garbage truck from the rectangular ring-shaped closed channel, realizing efficient loading by gravity while avoiding the garbage from falling to the ground, and preventing the leakage of odor and sewage to pollute the environment.

[0039] 2. In the method and system for loading domestic waste of the present invention, the cargo box is in a horizontal state for loading the waste. Compared with horizontal compression loading and vertical loading with the cargo box flipped, the present invention has a smaller drop of waste during loading, and the upward speed of the recoil airflow generated after the waste falls into the cargo box is relatively small. Moreover, during horizontal loading, the recoil airflow of the present invention will also move in the front and rear directions of the cargo box for buffering, further reducing the upward recoil speed of the recoil airflow. After the speed of the recoil airflow is reduced, the odor collection and treatment device can easily collect and treat the odor.

[0040] Horizontal compression loading or flipping vertical loading methods are difficult to collect due to the rapid rise of recoil airflow, and the generated odor seriously pollutes the environment, making it difficult to select a site for garbage transfer stations and, in turn, making it difficult to transport urban domestic waste. The vehicle-to-vehicle docking compression loading method, on the other hand, cannot be enclosed for loading and lacks odor collection and treatment measures, so odor is bound to overflow. The domestic waste loading method and system of the present invention, because it does not have the "high flow rate problem of recoil airflow," makes it easy to collect and treat odor, enabling the realization of low-odor or even odorless garbage transfer stations. This in turn makes it easier to select a site for the transfer station, facilitating the timely collection and transportation of urban domestic waste.

[0041] 3. The domestic waste loading method and loading system of the present invention can load and transport waste in a horizontal cargo box state, and there is no mechanism on the vehicle to change the cargo box state. Existing loading methods all require changing the cargo box state. If a mechanism is provided on the vehicle to change the cargo box state, it will significantly increase the vehicle's deadweight, which will reduce the effective load of the transportation; at the same time, changing the cargo box state will increase the loading safety risk. In order to control the loading safety risk, the effective loading capacity will also be significantly reduced, which will further reduce the effective load of the transportation vehicle. Since the present invention does not require changing the cargo box state, it can not only improve the loading safety of the garbage transport vehicle, but also significantly increase the effective load of the garbage transport vehicle, resulting in higher economic benefits. A 31-ton tractor using the present invention can legally transport 25 tons of garbage. Using the existing technology with a 31-ton traction mass: the horizontal type can only legally transport 16 tons of garbage, and the vertical type can only legally transport 15 tons of garbage.

[0042] 4. The domestic waste loading method and loading system of the present invention can allow the sewage accumulated in the front domestic waste truck to flow naturally from high to low into the garbage box of the garbage transport truck. When dumping the garbage, the accumulated sewage will not scatter and flow horizontally, and the loading is more environmentally friendly.

[0043] 5. In the method and system for loading domestic waste of the present invention, the telescopic sealing structure is rapidly retracted upward after the waste is loaded, and the lower end of the telescopic sealing structure can be rapidly sealed by a sealing plate or a cargo box of another waste transport vehicle. Simultaneously, the cargo box cover can be rapidly closed by a cargo box cover taking and placing device. The waste is exposed to the air for a short time, which can greatly reduce the odor in the waste from polluting the air.

[0044] 6. The domestic waste loading system of the present invention adopts a combustion deodorization device to burn the odor inside the telescopic sealing structure. The combustion deodorization device can also absorb the odor near the inlet and outlet of the telescopic sealing structure for combustion treatment, which can further eliminate the problem of garbage odor polluting the air.

[0045] 7. The domestic waste loading method and loading system of the present invention uses negative pressure to introduce the gas at the loading site into the combustion and deodorization device, which can completely eliminate the gas odor through combustion and has good environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Figure 1 is a schematic diagram of a garbage truck driving under a garbage loading hopper;

[0047] Figure 2 is a schematic diagram of the domestic garbage loading status. Best Mode for Carrying Out the Invention

[0048] The present invention will be further described below with reference to the accompanying drawings and examples.

[0049] The method for loading domestic garbage into a truck in this embodiment includes the following steps:

[0050] 1) The garbage truck drives to the bottom of the garbage loading hopper 2 of the garbage transfer workshop 1.

[0051] 2) When the cargo box of the garbage transport truck is in a horizontal state, the cargo box cover 3 of the garbage transport truck is removed, thereby completely opening the cargo box opening of the garbage transport truck.

[0052] 3) Controlling the telescopic sealing structure to extend downward to the cargo box opening of the garbage truck, thereby forming a rectangular ring seal between the cargo box opening of the garbage truck and the garbage loading hopper. The telescopic sealing structure is arranged outside the garbage loading hopper.

[0053] 4) The front-end domestic waste collection vehicle 6 entering the transfer workshop pours the waste into the garbage loading hopper, and the domestic waste falls from the garbage loading hopper into the cargo box of the garbage transport vehicle 7.

[0054] 5) Leveling the garbage in the cargo box in the rectangular annular sealed space. In the specific implementation, the leveling can be performed by a grabber 8. Of course, the leveling operation can be omitted when the garbage has not reached the cargo box opening.

[0055] 6) Control the telescopic sealing structure on the outside of the garbage loading hopper to retract and reset upward.

[0056] 7) Close the outlet of the telescopic sealing structure by means of a sealing plate.

[0057] 8) Close the cargo box cover of the garbage truck.

[0058] Of course, during the continuous loading operation, the sealing plate for closing the outlet of the telescopic sealing structure in step 7) can also be replaced by moving the cargo box of another garbage truck to the bottom of the outlet of the telescopic sealing structure to form a rectangular ring seal.

[0059] As an improvement to the above embodiment, the method for loading domestic waste into a truck further includes extracting gas from the rectangular annular sealed space and burning it for deodorization. During loading, a negative pressure is formed in the rectangular annular sealed space to prevent odor from leaking out.

[0060] The domestic waste loading system implementing the above-mentioned domestic waste loading method includes a garbage loading funnel 2 for introducing garbage into the cargo box of the garbage transport truck, a telescopic sealing structure 5 arranged outside the garbage loading funnel for forming a rectangular annular seal between the cargo box opening and the garbage loading funnel outlet, and a box cover picking and placing device 11 for picking up and placing the garbage transport truck cargo box cover.

[0061] In this embodiment, the telescopic sealing structure 5 includes a fixed sealing sleeve 51 disposed outside the garbage loading hopper, a movable sealing sleeve 52 that slides up and down with the fixed sealing sleeve, and a first linear motion actuator 54 for driving the movable sealing sleeve to move up and down. The first linear motion actuator can be a pneumatic cylinder or a hydraulic cylinder. In this embodiment, the first linear motion actuator is arranged vertically, and the lower end of the first linear motion actuator is fixedly arranged, specifically fixed to a building foundation 55. The outer side of the movable sealing sleeve has a support block 56 that cooperates with the upper end of the first linear motion actuator. When the first linear motion actuator is extended, the first linear motion actuator pushes the movable sealing sleeve 52 upward; when the first linear motion actuator is shortened, the movable sealing sleeve 52 moves downward. In a specific embodiment, when the movable sealing sleeve 52 moves downward until its lower end connects with the cargo box opening, a rectangular annular seal is formed. When the lower end of the movable sealing sleeve is connected to the cargo box opening, the upper end of the first linear motion actuator descends to form a gap with the support block 56. When loading garbage into the cargo box, as the amount of garbage in the cargo box increases, the pressure on the truck wheels increases. The wheels are compressed and deformed, causing the cargo box opening to gradually move downward. At this time, due to the gap between the upper end of the first linear motion actuator 54 and the support block 56, the movable sealing sleeve 52 can move downward with the cargo box opening under the action of its own weight, thereby ensuring that the lower end of the movable sealing sleeve 52 is always connected to the cargo box opening, so that the rectangular annular sealing structure will not be damaged by the lowering of the cargo box opening. Of course, in different embodiments, the first linear motion actuator 54 can also be arranged as shown in Figures 3 and 4.

[0062] To improve the above telescopic sealing structure, the telescopic sealing structure 5 further includes a rubber sealing skirt 53 provided at the lower end of the movable sealing sleeve. When loading, the rubber sealing skirt 53 surrounds the cargo box opening, which can improve the sealing effect.

[0063] As an improvement to the above-mentioned embodiment, the domestic waste loading system further includes a suspension 9 fixedly mounted outside the telescopic sealing structure, two sealing plates 4 mounted on the suspension for sealing the lower port of the telescopic sealing structure, and a drive device 10 for driving the two sealing plates to engage and disengage. In this embodiment, the drive device 10 includes a rack 101 mounted on the sealing plate, a gear 102 mating with the rack, and a motor 103 mounted on the suspension for rotating the gear. When there is no domestic waste in the garbage loading hopper, the drive device 10 drives the two sealing plates to close, sealing the outlet of the garbage loading hopper. This prevents odor from the garbage loading hopper and the transfer workshop from leaking out and polluting the air, and also prevents residual sewage from leaking out and polluting the surrounding environment.

[0064] As an improvement to the above embodiment, the suspension 9 is a rectangular sealed tube. The suspension 9 adopts a rectangular sealed tube structure to form a second layer of annular seal outside the telescopic sealing structure 5, which can better prevent odor from leaking out.

[0065] In this embodiment, the cargo lid retrieval device 11 comprises a hydraulic cylinder 111 with a telescopic rod extending vertically downward, a horizontal fork plate 112 connected to the hydraulic cylinder's piston rod, and a second linear motion actuator 113 for driving the hydraulic cylinder in translation. The second linear motion actuator can be a linear motor. In a specific implementation, to prevent the linear motor from interfering with the downward extension of the telescopic seal structure, the linear motor is positioned outside the telescopic seal structure. A horizontal plate is connected to the sliders of the two linear motion actuators, and the hydraulic cylinder 111 is positioned on the horizontal plate. This allows the linear motor to drive the horizontal plate and the hydraulic cylinder thereon to translate, allowing the horizontal fork plate to be inserted into or removed from a socket on the top of the cargo lid, enabling the cargo lid to be retrieved and placed. Of course, in different embodiments, the second linear motion actuator 113 can also be a conventional linear motion actuator, such as a crane or linear slide. Furthermore, the horizontal fork plate 112 can also be replaced with a movable connector, such as a hook. Of course, in different embodiments, the cargo lid retrieval device 11 can also take other forms.

[0066] As an improvement to the above-mentioned embodiment, the household waste loading system also includes a parking and positioning device for the garbage truck. In this embodiment, the parking and positioning device includes guide rails 12 for guiding the garbage truck to the bottom of the garbage loading hopper. The guide rails 12 define the position of the garbage truck along the width of the cargo box. The garbage truck travels between the guide rails 12, thereby defining its travel direction and aligning the center of the garbage truck's cargo box width with the center of the garbage loading hopper width. Furthermore, the parking and positioning device includes a parking distance positioning plate 13 that cooperates with a ranging radar installed on the front of the garbage truck. As the garbage truck moves forward, the ranging radar measures the distance to the parking distance positioning plate 13 in real time. When the measured distance reaches a set threshold, a ranging lightning alarm sounds an alarm to the driver, prompting the driver to stop. This ensures that the center of the cargo box length is aligned with the center of the garbage loading hopper length when the garbage truck stops. This ensures that household waste enters the cargo box accurately during loading. Of course, in different embodiments, the parking positioning device may also adopt other forms. For example, a stop mark line may be set under the garbage loading funnel, and a 360° panoramic image may be set on the garbage truck. The driver can observe the stop mark line through the panoramic image, thereby achieving accurate parking.

[0067] As an improvement to the above embodiment, the domestic waste loading system also includes a combustion and deodorization device, which includes a gas drainage pipe 14 connected to the space inside the fixed sealing sleeve, a combustion furnace 15 connected to the gas drainage pipe, a vertical combustion chamber 16 connected to the combustion furnace, an exhaust pipe 17 connected to the exhaust port of the vertical combustion chamber, an exhaust fan 18 arranged at the end of the exhaust pipe, and a cooling device arranged outside the vertical combustion chamber and the exhaust pipe. In this embodiment, the cooling device includes a cooling water tank 19 arranged outside the vertical combustion chamber and the exhaust pipe, and a cooling water pipe 20 wrapped around the outside of the vertical combustion chamber. The working principle of the combustion and deodorization device is as follows:

[0068] Exhaust fan 18 operates to draw garbage odor from within the telescopic seal structure and near its inlet and outlet into the incinerator. Ignition of the incinerator generates a high-temperature flame, which carbonizes and decomposes toxic and harmful substances in the garbage odor within the incinerator and vertical combustion chamber. In particular, the high temperature generated by the outer flame of the incinerator in the vertical combustion chamber fully carbonizes and decomposes the odor in the airflow, thereby achieving the purpose of disinfection and deodorization. The negative pressure generated by exhaust fan 18 draws garbage odor from near the outlet of the telescopic seal structure into the incinerator. This prevents the odor from spreading and contaminating the air, even when the telescopic seal structure is not in full contact with the cargo container opening.

[0069] The combustion and deodorization device in this embodiment utilizes a cooling device to reduce the temperature of the outer wall of the vertical combustion chamber, thereby extending the service life of the vertical combustion chamber. Cooling the exhaust pipe also reduces the temperature of the exhaust gas, which helps protect the exhaust fan. In a specific implementation, a number of small air intake holes 21 can be provided at the outlet of the exhaust pipe 17 to introduce cool air, further reducing the exhaust temperature and thus better protecting the exhaust fan. Furthermore, in a specific implementation, a diameter-enhanced section can be provided in the vertical combustion chamber. If the garbage odor remaining within the telescopic seal contains a high concentration of flammable gases, deflagration may occur upon introduction into the combustion furnace. This section can effectively buffer the shock wave generated by the deflagration, providing an explosion-proof effect. Furthermore, the negative pressure airflow generated by the exhaust fan 18 prevents combustion or explosion of the odor in the gas drainage pipe 14. The negative pressure airflow generated by the exhaust fan 18 allows a large amount of fresh air to enter the telescopic seal, suppressing the recurrence of odor.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
