Description

Technical Field

[0001] The invention relates to the field of waste treatment, and in particular to an airflow injection system for a garbage bin. Background Art

[0002] The domestic waste treatment process usually includes the following main links: collection, transportation and treatment.

[0003] Collection: The collection of domestic waste is the first step in the entire disposal process. Usually, the waste is placed in designated trash cans or bins and collected regularly by sanitation workers. Some cities have also adopted smart trash cans and waste sorting systems to improve collection efficiency and accuracy.

[0004] Transportation: The collected garbage will be transported to the designated treatment facilities. At present, the domestic garbage in the community is loaded onto electric tricycles, which are then transported to the garbage transfer station and unloaded. The unloaded garbage can be loaded into containers and then transported to the treatment site by large transport vehicles for treatment.

[0005] Treatment: Treatment includes a variety of methods, such as landfill, incineration, composting, etc. Landfill is the most common treatment method, but care must be taken to prevent groundwater and soil contamination. Incineration can reduce the volume of garbage, but emissions need to be strictly controlled to reduce the impact on the atmosphere. Composting is suitable for organic waste and can be converted into fertilizer.

[0006] At present, the large-scale transport vehicles for transporting garbage include dump trucks and semi-trailers. Dump trucks are equipped with a hydraulic lifting system. When unloading containers, the hydraulic lifting system converts the containers from a flat state to an inclined state, and unloads the garbage in the containers. Dump trucks are more convenient when unloading, but the disadvantage is that due to the heavy weight of the hydraulic lifting system, it will occupy part of the vehicle's quasi-load capacity, thereby reducing the loading weight of the container.

[0007] Since the semi-trailer is not equipped with a hydraulic lifting system, the loading weight of the container is larger than that of the container on a dump transport vehicle. However, at the garbage disposal site, an extraction device (crane) and a hydraulic lifting device must be installed to extract the container. The extraction device extracts the container and releases it to the hydraulic lifting device. The container is tilted by the hydraulic lifting device to unload the materials in the container.

[0008] For some garbage disposal sites, the installation of extraction devices and hydraulic lifting devices in the disposal sites will be restricted due to comprehensive factors such as construction cost and floor space. In addition, some disposal sites do not allow the installation of extraction devices and hydraulic lifting devices due to cost considerations alone. Therefore, the transportation of containers loaded with garbage by semi-trailers is restricted. Summary of the invention

[0009] The invention provides a garbage bin airflow injection system with a simple structure and low cost, which can save the construction cost of a material unloading site and the cost of purchasing an extraction device and a hydraulic lifting device.

[0010] A waste bin air jetting system, including a waste loading bin, further comprising:

[0011] A gas supply main pipeline, the gas supply main pipeline is installed on the garbage loading box;

[0012] a first branch pipeline, the first branch pipeline is connected to the gas supply main pipeline, and the first branch pipeline is installed on the side of the garbage loading box;

[0013] A first jet component, a first mounting hole is provided on the side of the garbage loading box, the first jet component is installed on the side of the garbage loading box and matches with the first mounting hole, a first air inlet and a first air outlet that is connected with the first air inlet are provided on the first jet component, the first air inlet is connected with the first branch pipe, and the outlet of the first air outlet is located inside the garbage loading box;

[0014] The first valve is installed on the first branch pipeline.

[0015] The advantages of the present invention are:

[0016] After the garbage bin airflow injection system of the present invention arrives at the unloading site, the door at the rear of the garbage loading bin is opened to expose the door and correspond to the unloading pit, and the high-pressure gas supply system is connected. By controlling the opening sequence of the first valve installed on the garbage loading bin, the garbage in the front section, middle section and rear section of the garbage loading bin is blown out in sequence by high-pressure air. Therefore, the structure of the present invention does not need to install the extraction device and hydraulic lifting device of the garbage loading bin at the unloading site, which reduces the area occupied by the unloading site and saves the construction cost of the site and the cost of purchasing the extraction device and hydraulic lifting device.

DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] First embodiment

[0036] like Figures 1 to 10As shown, the garbage bin airflow injection system of this embodiment includes a garbage loading box 1, an air supply main pipeline 2, a first branch pipeline 3, a first injection component 4, and a first valve 5. Each part is described in detail below.

[0037] The main gas supply pipeline 2 is installed on the garbage loading box 1. The main gas supply pipeline 2 is a pipeline that can withstand high pressure. The main gas supply pipeline 2 can be a hose or a steel pipe. The main gas supply pipeline 2 includes a first main pipeline 2a that matches the end of the garbage loading box 1 and a second main pipeline 2b that matches the side of the garbage loading box 1. In this embodiment, the first main pipeline 2a is U-shaped, and the first main pipeline 2a matches the left side, top and right side of the garbage loading box 1. The second main pipeline 2b is arranged on the left side and right side of the garbage loading box 1. In this embodiment, the main gas supply pipeline 2 preferably uses a steel pipe. The first main pipeline 2a is provided with an air inlet interface 2d, and the air inlet interface 2d is used to connect a high-pressure gas supply system (not shown in the figure). The high-pressure gas supply system can use an air compressor.

[0038] The first branch pipe 3 is connected to the gas supply main pipe 2, and the first valve 5 is installed on the first branch pipe 3. The first branch pipe 3 is installed on the side of the garbage loading box 1; in this embodiment, there are multiple first branch pipes 3, which are arranged at intervals along the length direction of the garbage loading box 1, and the material of the first branch pipe 3 is the same as that of the gas supply main pipe 2.

[0039] The first branch pipe 3 includes a first main branch pipe 3a and a first branch pipe 3b. The first main branch pipe 3a is arranged along the height direction of the garbage loading box 1. One end of the first main branch pipe 3a is connected to the second main pipe 2b. The first branch pipe 3b is connected to the first main branch pipe 3a. The first branch pipe 3b is arranged along the length direction of the garbage loading box 1. In this embodiment, two first branch pipes 3b are connected to each first main branch pipe 3a. The first valve 5 is installed on the first main branch pipe 3a. One first valve 5 is installed on each first main branch pipe 3a.

[0040] A first mounting hole is provided on the side of the garbage loading box 1, and a first jet component 4 is installed on the side of the garbage loading box 1 and cooperates with the first mounting hole. A first air inlet 4a and a first air outlet 4b communicating with the first air inlet 4a are provided on the first jet component 4. The first air inlet 4a is connected to the first branch pipe 3, and the first air inlet 4a cooperates with the first branch pipe 3b. The outlet of the first air outlet 4b is located inside the garbage loading box 1.

[0041] There are multiple first air outlets 4b, and the axial direction of the first air outlets 4b is not parallel to the axial direction of the first jetting component 4, that is, an angle is formed between the axial direction of the first air outlets 4b and the axial direction of the first jetting component 4. In addition, the axial direction of the first air outlets 4b is not perpendicular to the axial direction of the first air inlet 4a. When the compressed gas is ejected from the first jetting component 4, the ejection angle is inclined relative to the width direction of the garbage loading box 1, and the inclined direction is toward the door 1a of the garbage loading box 1, so that the garbage in the garbage loading box 1 is thrusted toward the door 1a under the action of the high-pressure gas.

[0042] This embodiment also includes a second branch pipe 6, a second jet component 7, and a second valve 8. The second branch pipe 6 is located at the top of the garbage loading box 1, and the second branch pipe 6 is connected to the gas supply main pipe 2. In this embodiment, the second branch pipe 6 is connected to the first main pipe 2a, and the second valve 8 is installed on the second branch pipe 6.

[0043] A second mounting hole is provided on the top of the garbage loading box 1, and a second jet component 7 is installed on the top of the garbage loading box 1 and cooperates with the second mounting hole. A second air inlet 7a and a second air outlet 7b communicating with the second air inlet 7a are provided on the second jet component 7. The second air inlet 7a is connected to the second branch pipe 6, and an outlet of the second air outlet 7b is located inside the garbage loading box 1.

[0044] The second air inlet 7a is arranged along the axial direction of the second jet component 7, and the second air inlet 7a passes through the axial end surface of the second jet component 7. Therefore, the second air inlet 7a is a through hole, and both ends of the second air inlet 7a are respectively matched with the second branch pipe 6. The axial direction of the second air outlet 7b is inclined to the axial direction of the second air inlet 7a.

[0045] The present embodiment further includes a protection assembly 9, which includes a top plate 9a, a left side plate 9b, and a right side plate 9c. The top plate 9a, the left side plate 9b, and the right side plate 9c form a U-shaped structure. After the protection assembly 9 is covered on the garbage loading box 1, the top plate 9a cooperates with the top of the garbage loading box 1, the left side plate 9b cooperates with the left side of the garbage loading box 1, and the right side plate 9c cooperates with the right side of the garbage loading box 1. Then, the protection assembly 9 blocks the gas supply main pipeline 2, the first branch pipeline 3, the first jet component 4, the first valve 5, the second branch pipeline 6, and the second valve 8 to prevent the gas supply main pipeline 2, the first branch pipeline 3, the first jet component 4, the first valve 5, the second branch pipeline 6, and the second valve 8 from being damaged due to collision, friction, and the like.

[0046] In this embodiment, a first clearance hole 9d and a second clearance hole 9e are provided on the protection component 9. The first clearance hole 9d is arranged on the right side plate 9c, and the second clearance hole 9e is arranged on the top plate 9a. The air inlet interface 2d cooperates with the first clearance hole 9d, and the second jet component 7 cooperates with the second clearance hole 9e.

[0047] The working process of this embodiment is:

[0048] After the vehicle carrying the garbage bin airflow injection system of the present embodiment reaches the unloading site, the door of the rear part of the garbage loading bin 1 is opened, so that the door 1a of the garbage loading bin 1 is exposed to the air. Since three first valves 5 are arranged on the left and right sides of the garbage loading bin 1 in the present embodiment, the two left and right first valves 5 at the same length position along the length direction of the garbage loading bin 1 form a group, so there are three groups of first valves 5 in total. After the high-pressure gas supply system is connected to the air inlet interface 2d, the first group of first valves 5 closest to the door 1a is opened first. After the high-pressure air is ejected through the main air supply pipeline 2, the first branch pipeline 3, and the first injection component 4, the force of the high-pressure air acts on the garbage in the front section of the garbage loading bin 1, so that the garbage is gradually loosened, and the garbage is blown out to the outside of the garbage loading bin 1 under the continuous force of the high-pressure air (such as Fig.11 ). Then, the second group of first valves 5 located in the middle position are opened, and the garbage in the middle section of the garbage loading box 1 is blown out by the continuous force of high-pressure air. Then, the third group of first valves 5 farthest from the door 1a is opened, and the garbage in the rear section of the garbage loading box 1 is blown out by the continuous force of high-pressure air. Finally, the second valve 8 is opened, and the high-pressure gas is output from the top to act on the inner wall of the front end of the garbage loading box 1. After the compressed air passes through the inner wall of the front end of the garbage loading box 1 in the reverse direction, the remaining garbage in the garbage loading box 1 is blown out.

[0049] Second embodiment

[0050] The differences between this embodiment and the first embodiment are as follows:

[0051] like Figure 12 to Figure 14 , the second main pipeline 2b is connected to the first main pipeline 2a to form a U-shaped structure, the second main pipeline 2b is integrally formed with the first main pipeline 2a, and is formed into the U-shaped structure after being bent. The gas supply main pipeline 2 also includes a third main pipeline 2c, one end of the third main pipeline 2c is connected to the first main pipeline 2a, and the other end of the third main pipeline 2c extends to the top of the garbage loading box 1, and the other end of the third main pipeline 2c is connected to the second branch pipeline 6. The third main pipeline 2c is L-shaped, a part of the third main pipeline 2c cooperates with the front side of the garbage loading box 1, and another part of the third main pipeline 2c cooperates with the top of the garbage loading box 1.

[0052] like Fig.15 The protection assembly in this embodiment also includes a rear side plate 9f, the top plate 9a cooperates with the top of the garbage loading box 1, the rear side plate 9f is used to cooperate with the front side of the garbage loading box 1, and the first clearance hole 9d is set on the rear side plate 9f.

[0053] In summary, in the present invention, the garbage loading box 1 can be a new container or an existing loading box. The existing loading box is, for example, a hydraulic push plate type box. A set of push plates of the existing hydraulic push plate type box weighs about 1.5-2 tons and occupies space in the box, while the space occupied by the present invention is almost negligible. Therefore, the system of the present invention can first reduce the total amount of extra garbage and secondly does not occupy space in the box. According to a medium-to-large transfer station equipped with 600 garbage compacting trucks, one truck can save 1.5 tons of dead weight and about 2m 3 The space can provide an additional 140 tons (garbage density 0.7) of transportation capacity, greatly improving efficiency and reducing operating costs.
