Description
Technical Field
[0001] The invention relates to the technical field of domestic waste transportation, and in particular to a cargo box of a waste transportation vehicle. Background Art
[0002] In order to prevent the odor from leaking out, the existing domestic waste transport trucks implement closed transportation. The cargo box of the domestic waste transport truck is provided with a domestic waste loading port and a sealing cover that matches the domestic waste loading port, and a sealing sleeve is provided on the sealing cover. The composition of domestic waste is complex, and most of it is corrosive. Domestic waste will produce odor when it decays and ferments in the closed cargo box. The main reasons for the odor leakage in the cargo box of the domestic waste transport truck include:
[0003] First, hard or coarse household garbage gets stuck on the sealing sleeve, causing the sealing cover to be loose and a gap that leaks odor. If garbage gets stuck on the sealing sleeve many times, it will damage the sealing sleeve, causing small holes on the sealing sleeve that leak odor.
[0004] Second, the aging deformation and aging damage of the sealing sleeve cause the sealing cover to be not tightly sealed. The temperature difference between hot and cold is large when the domestic waste transport truck is working, and the domestic waste is highly corrosive, so the sealing sleeve is easy to age and the sealing function is reduced. In addition, the testing of the sealing function of the sealing cover of the domestic waste transport truck requires professional equipment and strict procedures. This kind of professional testing is difficult for front-line sanitation personnel to complete, which will cause small holes in the sealing sleeve and it is difficult to detect when it is damaged. However, the odor can leak from these holes and damaged parts to pollute the air. Summary of the invention
[0005] In view of this, the purpose of the present invention is to provide a method for preventing odor from leaking from the cargo box and a device for the cargo box of a trailer loaded with domestic garbage, so as to solve the technical problem that the sealing cover is not tightly sealed, causing odor to leak from the cargo box and pollute the air.

When the compression loading area is full, the compression mechanism stops working. When domestic garbage is loaded into the gravity natural loading area again, an odor collection chamber is reserved between the top of the garbage in the gravity natural loading area and the automatic sealing cover;
[0008] The odor in the odor collection chamber is continuously extracted to keep the odor collection chamber in a negative pressure state. The negative pressure allows the air outside the cargo box to flow into the odor collection chamber from the pores of the matching part of the automatic sealing cover and the garbage loading port to prevent the odor in the cargo box from leaking out; and the extracted odor is sent to the deodorization device for deodorization.
[0009] The present invention also discloses a trailer cargo box device according to the above-mentioned method for preventing odor in a trailer cargo box loaded with domestic garbage, comprising a frame and a cargo box arranged on the frame, wherein the inner cavity of the cargo box is composed of a compression loading area and a gravity natural loading area, and the gravity natural loading area is located at the front of the cargo box; a garbage loading inlet and an automatic sealing cover cooperating with the garbage loading inlet are arranged at the top of the gravity natural loading area;

[0020] Beneficial effects of the present invention:
[0021] 1. The present invention provides a method for preventing odor in a cargo box of a trailer loaded with domestic garbage and a device for the cargo box of a trailer loaded with domestic garbage. When the natural gravity loading area is filled with domestic garbage, an odor collecting chamber is left between the top of the domestic garbage and the automatic sealing cover. The odor collecting chamber is evacuated, and the inside of the odor collecting chamber is in a negative pressure state. The air outside the cargo box of the trailer flows into the odor collecting chamber from the gap or / and the small hole at the edge of the sealing cover in one direction, and the odor in the cargo box cannot flow out of the sealing cover in the reverse direction. The odor extracted is sent to a deodorizing device for deodorization and purification, and then discharged after deodorization, thereby solving the technical problem of odor leakage from the cargo box of the existing garbage transport vehicle polluting the air due to the loose sealing cover.
[0022] 2. The deodorization method of the trailer cargo box loaded with domestic garbage of the present invention divides the trailer cargo box into a compression loading area and a gravity natural loading area. The compression loading area is at the rear of the trailer cargo box and the gravity natural loading area is at the front of the trailer cargo box. The garbage is directly loaded into the gravity natural loading area without being compressed, and the loading efficiency is high. After entering the gravity natural loading area, the sealing cover is first covered, and then the negative pressure pumping is combined to prevent odor leakage and the compression mechanism is used to push the garbage into the compression loading area for compression. Large-volume loading and environmentally friendly loading are achieved at the same time, which is an advantage that existing garbage trucks do not have. In addition, the present invention continuously pumps air from the odor collection chamber, which can always ensure that the odor in the cargo box does not leak out. This can better prevent odor leakage compared with the existing technical solution of preventing odor leakage by sealing.
[0023] 3. The deodorizing method and device for the trailer cargo box loaded with domestic waste of the present invention can be placed at the garbage collection area of the community because the trailer cargo box prevents odor leakage through negative pressure suction, and the environment does not smell when loading or placing domestic waste. After loading the domestic waste, the trailer cargo box is towed by a trailer for transportation, which is not only environmentally friendly but also can improve the efficiency and volume of garbage transfer. The device is also provided with a garbage can lifting and dumping device. After being placed in the community, cleaning staff and community staff can operate it themselves to dump garbage at any time, which is very convenient. The deodorizing method and device for the trailer cargo box loaded with domestic waste of the present invention are superior to the existing hook-arm garbage collection box and garbage compression collection truck in terms of environmental protection, convenience and loading capacity.

[0026] Figure 3 Schematic diagram of the internal structure of the trailer cargo box device. DETAILED DESCRIPTION
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] In this embodiment, the method for deodorizing the cargo box of a trailer loaded with domestic garbage includes dividing the cargo box into a compression loading area and a gravity natural loading area. The gravity natural loading area is located at the front of the cargo box. The top of the gravity natural loading area is provided with a garbage loading inlet and an automatic sealing cover that cooperates with the garbage loading inlet.
[0029] Domestic garbage is poured into the gravity natural loading area from the garbage loading port, and the domestic garbage in the gravity natural loading area is pushed into the compression loading area by the compression mechanism. When the compression loading area is full, the compression mechanism will no longer work. When domestic garbage is loaded into the gravity natural loading area, a odor collection chamber is reserved between the top of the garbage in the gravity natural loading area and the automatic sealing cover. The height of the odor collection chamber is preferably 10-30 cm, and the volume and height of the odor collection chamber are appropriate, which can ensure that a large negative pressure is formed in the chamber when the air is pumped to prevent the odor from leaking. In addition, since the garbage in the gravity natural loading area is naturally loaded by gravity and has a stable volume, even if the garbage shakes up and down during transportation, the odor collection chamber will not be completely blocked due to the expansion of the garbage volume.
[0030] The odor in the odor collection chamber is continuously extracted to keep the odor collection chamber in a negative pressure state. The negative pressure allows the air outside the cargo box to flow into the odor collection chamber from the pores of the matching part of the automatic sealing cover and the garbage loading port to prevent the odor in the cargo box from leaking out; and the extracted odor is sent to the deodorization device for deodorization.
[0031] The trailer cargo box device according to the method for deodorizing a trailer cargo box loaded with domestic garbage in the above-mentioned embodiment includes a frame 1 and a cargo box 2 arranged on the frame, the inner cavity of the cargo box 2 is composed of a compression loading area 201 and a gravity natural loading area 202, and the gravity natural loading area is located at the front part of the cargo box; the top of the gravity natural loading area is provided with a garbage loading port 3 and an automatic sealing cover cooperating with the garbage loading port.
[0032] In this embodiment, the automatic sealing cover includes a cover plate 4, a rectangular frame 5 provided at the edge of the garbage loading port and sealingly matched with the edge of the cover plate, and a linear drive 7 for driving the cover plate to translate longitudinally along the cargo box. The linear drive 7 in this embodiment is a hydraulic cylinder. Of course, in different embodiments, the linear drive 7 can also be in the form of an electric screw rod, a chain conveyor, or other forms. A rubber sealing strip can also be provided on the cover plate 4 or the rectangular frame 5 to improve the sealing between the cover plate 4 and the rectangular frame 5.
[0033] The trailer cargo box device also includes a compression mechanism for pushing the domestic garbage in the natural gravity loading area into the compression loading area. In this embodiment, the compression mechanism also includes a working box 8 located at the front end of the cargo box, a hydraulic cylinder 9 arranged in the working box, and a pressure plate 10 arranged in the cargo box, and the piston rod of the hydraulic cylinder is connected to the pressure plate.
[0034] The trailer cargo box device also includes an air pump 11 for extracting gas from the odor collection chamber at the top of the gravity natural loading area and a deodorizing device for purifying the gas extracted by the air pump. The air inlet of the air pump is connected to the odor collection chamber at the top of the gravity natural loading area 202 through a first pipe 12, and the air outlet of the air pump is connected to the deodorizing device through a second pipe 13. In this embodiment, the air pump and the deodorizing device are arranged in the working box; of course, the air pump and the deodorizing device can also be arranged on the frame or cargo box outside the working box. In this embodiment, the deodorizer includes a container 14, a deodorant contained in the container, and an exhaust pipe 15 arranged at the top of the container. The deodorant can be a plant-based deodorant or a chemical deodorant, etc. Of course, in the specific implementation, the deodorizer can also take other forms, such as a filtering deodorizer or a microbial deodorizer, or a series combination of different types of deodorizers.
[0035] In actual work, the linear drive 7 drives the cover plate 4 to move and open the garbage loading port 3, and then loads the garbage from the garbage loading port 3 into the gravity natural loading area 202. After loading is completed, the linear drive 7 drives the cover plate 4 to reset and close the garbage loading port 3. Then the hydraulic cylinder 9 is controlled to drive the pressing plate 10 to move and push the garbage in the gravity natural loading area 202 into the compression loading area 201 for compression, thereby increasing the loading capacity of the cargo box. The air pump continues to work, and the air pump 11 pumps the odor in the cargo box into the deodorizer from above the gravity natural loading area 202, and the air is pumped to make the odor collection chamber in a negative pressure state. The air outside the trailer cargo box flows into the odor collection chamber from the gap or / and the small hole on the edge of the sealing cover in one direction, and the odor in the cargo box cannot flow out of the sealing cover in the reverse direction. The gas treated by the deodorizer is then discharged through the exhaust pipe 15, thus avoiding the problem of the odor in the cargo box being directly discharged into the air and causing air pollution. When unloading garbage, open the box door at the rear end of the cargo box, and control the hydraulic cylinder 9 to drive the pressing plate 10 to push the garbage out of the cargo box.
[0036] As an improvement to the above embodiment, the vehicle cargo box device further comprises a guide bar 16 arranged on the top of the cargo box to guide the movement direction of the cover plate. Under the guidance of the guide bar 16, the cover plate 4 can reliably enter the rectangular frame 5.
[0037] As an improvement to the above embodiment, the trailer cargo box device further comprises a hydraulic station 17 arranged in the working box to control the operation of the hydraulic cylinder. Of course, in different embodiments, the hydraulic station 17 to control the operation of the hydraulic cylinder can also be arranged in other places.
[0038] As an improvement to the above embodiment, the trailer cargo box device further comprises a power supply 18 arranged in the working box for supplying power to the air pump and the hydraulic station. Of course, in different embodiments, the power supply 18 can also be arranged in other places.
[0039] As an improvement to the above embodiment, the trailer cargo box device also includes a trash can lifting and dumping device 19 arranged on the cargo box for dumping the trash in the trash can into the gravity natural loading area. By setting the trash can lifting and dumping device, the trash in the trash can can be conveniently loaded into the gravity natural loading area 202, and the loading efficiency is high.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. 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 solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
