[0001] This utility model relates to the technical field of waste treatment, specifically to a waste leachate deodorization device. Background Technology

[0002] Waste refers to solid and fluid substances that are not needed or are useless, including two main categories: industrial waste and domestic waste. With the growth of the urban population, domestic waste is increasing at a rate of 10% per year, posing a major public hazard. Landfill leachate is the liquid produced during the dumping, landfilling or treatment of waste, and it is also one of the main sources of waste odor.

[0003] Current landfill methods typically involve burying leachate along with the garbage, which causes the leachate to pollute surrounding water bodies and soil, resulting in foul odors around the landfill site, making it uninhabitable. Therefore, it is necessary to deodorize the leachate when burying garbage. Utility Model Content

[0014] The beneficial effects of this utility model are:

[0015] 1. This type of landfill leachate deodorization device, by setting up a treatment tank, a blower, a bend in the pipe, and an activated carbon layer, utilizes the special structure inside the treatment tank to concentrate the leachate squeezed out of the landfill into the collection chamber inside the treatment tank. Then, under the suction of the blower, the odor in the collection chamber will enter the deodorizing agent in the deodorization chamber through the bend in the deodorization chamber, and at the same time, the particulate matter in the odor will be precipitated. Afterwards, when the gas is transported to the filtration chamber, the activated carbon layer will further adsorb the odor, thereby achieving the purpose of deodorization.

[0016] 2. This type of landfill leachate deodorization device, by setting up a squeezing box, squeezing components, and electric push rods, allows the squeezing components to squeeze the waste after it is poured into the squeezing box through the feed hopper. The baffles on the squeezing components prevent the waste remaining in the feed hopper from sliding down. When the waste in the squeezing box is squeezed by the squeezing components, the leachate in the waste will enter the treatment tank through the filtrate holes. After the waste squeezing is completed, the two electric push rods will drive the tank door to rise, and then the squeezed waste will be pushed out of the squeezing box by the squeezing components, facilitating the centralized recycling of waste.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a landfill leachate deodorization device, comprising a treatment box 1, a squeezing box 2, and a feeding hopper 3. The squeezing box 2 is installed on one side above the treatment box 1, and the feeding hopper 3 is connected to the upper plate of the squeezing box 2. Several exhaust ports are installed on the outside of one side plate of the treatment box 1, penetrating into the treatment box 1 to form an exhaust fan 4. Two partitions are provided inside the treatment box 1. A bent pipe 5 is provided on the partition on the side of the treatment box 1 away from the exhaust fan 4. Several activated carbon layers 6 are provided on the side of the treatment box 1 near the exhaust fan 4. A sliding squeezing element 7 is provided inside the squeezing box 2. Electric push rods 8 are installed at both ends on the other side of the squeezing box 2, and a box door 9 that cooperates with the squeezing box 2 is provided between the output ends of the two electric push rods 8. A filtrate hole 10 is opened on the bottom plate of the squeezing box 2 near the box door 9.

[0025] The processing box 1 has a vertical mounting base 11 on its top plate. Two hydraulic push rods 12 are mounted on the mounting base 11, and the output ends of the two hydraulic push rods 12 are fixed together with the extrusion component 7. By setting up the mounting base 11 and the hydraulic push rods 12, the hydraulic push rods 12 can extrude the waste in the extrusion box 2 after being activated, so as to squeeze out the leachate in the waste.

[0026] The upper end of the extruder 7 is fixedly connected to a baffle 13 that contacts the top of the inner wall of the extrusion box 2, and the shape of the baffle 13 matches the lower port of the feed hopper 3. By setting the baffle 13, the residual garbage in the feed hopper 3 can be prevented from falling downward during the extruder 7 extruding garbage.

[0027] The treatment chamber 1 is divided into a collection chamber, a deodorization chamber, and a filtration chamber by two partitions. The activated carbon layer 6 is located in the filtration chamber. By setting partitions in the treatment chamber 1, the liquids in the collection chamber and the deodorization chamber can be prevented from coming into contact and mixing.

[0028] The treatment box 1 has an inclined plate 14 on one side, and the inclined plate 14 is located on the same side as the door 9. The upper part of the partition on the side of the treatment box 1 near the activated carbon layer 6 is provided with a splash guard 15. By setting the inclined plate 14, it is convenient to slide the squeezed garbage off the squeezing box 2. By setting the splash guard 15, it is prevented that the liquid in the deodorization chamber splashes into the filter chamber.

[0029] The treatment box 1 has a detachable movable door 16 on one side, and several activated carbon layers 6 are installed on the movable door 16. The edges of the activated carbon layers 6 are provided with sealing strips. The movable door 16 facilitates the replacement of the activated carbon layers 6.

[0030] The treatment tank 1 has a first inlet 17, a first waste outlet 18, a second inlet 19, and a second waste outlet 20 that are installed through one side wall. The positions of the first inlet 17 and the first waste outlet 18 correspond to the collection chamber of the treatment tank 1, and the positions of the second inlet 19 and the second waste outlet 20 correspond to the deodorization chamber of the treatment tank 1. The positions of the first inlet 17 and the second inlet 19 are higher than the first waste outlet 18 and the second waste outlet 20. By setting the first inlet 17, the first waste outlet 18, the second inlet 19, and the second waste outlet 20, it is convenient to add medicine to the collection chamber and the deodorization chamber and to discharge wastewater.

[0031] During operation, antibacterial solution is added to the collection chamber of the treatment box 1 through the first inlet 17, and deodorant is added to the deodorization chamber of the treatment box 1 through the second inlet 19, ensuring that the deodorant covers the lower end of the bend 5. Both the antibacterial solution and the deodorant are existing technologies. Garbage is fed into the feed hopper 3 and falls into the squeezing box 2. Then, the hydraulic push rod 12 is activated to squeeze the garbage with the squeezing component 7. When the squeezing component 7 moves, the baffle 13 on the squeezing component 7 can prevent the garbage remaining in the feed hopper 3 from sliding down. When the garbage in the squeezing box 2 is squeezed by the squeezing component 7, the leachate in the garbage will enter the collection chamber of the treatment box 1 through the filtrate hole 10. After the garbage squeezing is completed, the two electric push rods 8 will drive the box door 9 to rise. Then, the garbage that has been squeezed into pieces will be pushed out of the squeezing box 2 by the squeezing component 7, which facilitates the centralized recycling of garbage.

[0032] Afterwards, the leachate squeezed out from the garbage will be collected in the collection chamber inside the treatment tank 1. Then, the exhaust fan 4 will be turned on, and the exhaust fan 4 will draw out the air in the treatment tank 1. Under the action of air pressure, the odor in the collection chamber will enter the deodorizing agent in the deodorizing chamber through the bend pipe 5. At the same time, the particulate matter in the odor will be precipitated. Afterwards, when the gas is transported to the filter chamber, the activated carbon layer 6 will further adsorb the odor, thereby achieving the purpose of deodorization. The waste liquid in the collection chamber and the deodorizing chamber can be discharged through the first waste outlet 18 and the second waste outlet 20, respectively.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
