Description

Technical Field

[0001] This utility model relates to the field of landfill leachate tailwater treatment technology, and more specifically, to an aeration device for landfill leachate tailwater treatment. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater generated during landfilling or dumping of waste. Its composition is complex, containing large amounts of organic matter, ammonia nitrogen, heavy metals, and other pollutants. Landfill leachate effluent is the wastewater remaining after a series of preliminary treatment processes, requiring further intensive treatment. Aeration equipment plays a crucial role in the treatment of landfill leachate effluent. By introducing air or oxygen into the water, the dissolved oxygen content is increased, providing a favorable living environment for microorganisms and promoting the decomposition and transformation of pollutants, thereby purifying the effluent.

[0003] Currently, the aeration section of aeration equipment is typically installed at the bottom of the treatment tank. Because landfill leachate contains a large amount of solid particles, such as silt and organic residue, these particles may enter the micropores of the aeration discs during aeration. Over time, this accumulation can clog the micropores, reducing gas flow and aeration efficiency. Therefore, regular inspection and cleaning are necessary. However, because the aeration equipment is installed at the bottom of the treatment tank, inspection and cleaning require draining the leachate first, followed by staff descending into the tank for maintenance. This makes cleaning and inspection inconvenient, and the limited space inside the tank further complicates the process, making it time-consuming and labor-intensive. Therefore, we propose an aeration device for landfill leachate effluent treatment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an aeration device for treating landfill leachate tailwater, so as to solve the technical problem that the cleaning and inspection of the current aeration device installed at the bottom of the treatment tank is troublesome, time-consuming and labor-intensive.

[0005] To solve the above technical problems, the present invention provides the following technical solution: an aeration device for treating landfill leachate tailwater, comprising an aeration component installed at the bottom of a treatment tank, an air blowing component connected to the aeration component fixedly installed on one side of the treatment tank, and two winding mechanisms fixedly installed on the outer sides of both ends of the treatment tank at the aeration component, wherein a pull strap fixedly connected to the aeration component is fixedly installed inside the winding mechanism.

[0006] The air blowing assembly includes a blower, the output end of which is fixedly installed with an adapter pipe, and the other end of the adapter pipe is detachably installed with a connecting pipe that communicates with the aeration assembly.

[0007] The aeration component has a fixed plate at both ends of its bottom, a connecting seat at both ends of its top, and a connector head that is fixedly connected to the connecting seat at the lower end of the pull strap.

[0008] This invention utilizes a fixed plate structure at the bottom of both ends of the aeration component, which can be connected to a pull belt. This allows the aeration component to be lifted from the bottom of the treatment tank by the winding mechanism. The detachable structure of the blowing component ensures that the upward movement is not hindered. This method eliminates the need to clean the effluent in the treatment tank when cleaning and inspecting the aeration component, and also eliminates the need for personnel to enter the tank, effectively saving time and effort.

[0009] Preferably, the winding mechanism includes a frame body, on which a drive rod, a transmission rod, and a winding rod are rotatably mounted on opposite sides. A first gear set is meshed between the drive rod and the transmission rod, and a second gear set is meshed between the transmission rod and the winding rod.

[0010] Preferably, a circular plate is fixedly provided on the outer wall of one end of the transmission rod, and a ratchet is fixedly provided on the side of the circular plate. A fixing rod is fixedly installed between the inner walls of the frame body and diagonally above the drive rod. A pawl that cooperates with the ratchet is rotatably installed on the wall of the fixing rod.

[0011] Preferably, a connecting rod is fixedly connected between the two drive rods on one side, and a drive motor that is fixedly connected to the outer wall of the frame body is fixedly installed on the side end of the drive rod on one side.

[0012] Preferably, a guide is fixedly provided at the top of the treatment pool near the winding mechanism, and the outer wall of the pull belt is in contact with the inner wall of the guide.

[0013] Preferably, the guide includes two vertical plates, two guide rods for clamping the pull belt are rotatably mounted on the two vertical plates, a support plate that fits against the bottom side of the pull belt is fixed on one side of the two vertical plates near the aeration component, and a scraper that fits against the top of the pull belt is fixed between the two opposite sides of the support plate.

[0014] Preferably, the side end of the adapter pipe is constructed with a connecting groove that engages with the side end of the connecting pipe, and an arc-shaped cover plate that fits against the top of the connecting pipe is fixedly installed on the top of the connecting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a fixed plate structure at the bottom of both ends of the aeration component to connect with a pull belt. Under the action of the winding mechanism, the aeration component can be lifted from the bottom of the treatment tank as a whole. With the detachable structure of the blowing component, the upward movement can be carried out without affecting the operation. In this way, the step of cleaning the tailwater in the treatment tank can be eliminated when cleaning and inspecting the aeration component, and the step of workers entering the tank can also be eliminated, which effectively saves the time required for cleaning and inspection, saving time and effort.

[0017] 2. This utility model also uses a circular plate structure on the transmission rod wall to fix the installation position of the ratchet. In this way, the ratchet and ratchet on the fixed rod can cooperate to achieve an automatic locking effect, so that the winding mechanism cannot rotate in reverse during the winding process. This also maintains the stability of the lifting height of the aeration component when the drive motor fails, further enhancing the safety of the structure.

[0018] 3. This utility model also provides tension support for the pull belt through the structural design of the guide component, keeping the pull belt moving smoothly during winding and unwinding. At the same time, the scraper structure on the guide component can scrape off the tail water and impurities adhering to the surface of the pull belt, which can improve the cleanliness of the pull belt during winding and further enhance the cooperation effect between the structures.

[0028] like Figures 1 to 8 As shown, this utility model relates to an aeration device for treating landfill leachate tailwater, including an aeration component 1 installed at the bottom of a treatment tank, an air blowing component 2 fixedly installed on one side of the treatment tank and communicating with the aeration component 1, and two winding mechanisms 3 fixedly installed on the outer sides of both ends of the treatment tank at the aeration component 1. The winding mechanism 3 has a pull strap 5 fixedly installed inside and fixedly connected to the aeration component 1. The connection between the aeration component 1 and the air blowing component 2 enables aeration, and the connection between the pull strap 5 and the aeration component 1 can be easily lifted from the treatment tank by the control of the winding mechanism 3, thereby facilitating the cleaning and maintenance of the aeration component 1.

[0029] The air blowing assembly 2 includes a blower 201. An adapter pipe 202 is fixedly installed at the output end of the blower 201. A connecting pipe 203 that communicates with the aeration assembly 1 is detachably installed at the other end of the adapter pipe 202. The detachable connection between the adapter pipe 202 and the connecting pipe 203 allows the aeration assembly 1 to be separated when it moves upward without affecting the upward movement operation.

[0030] A fixing plate 101 is fixedly provided at the bottom of both ends of the aeration component 1, and a connecting seat 102 is fixedly provided at the top of both ends of the fixing plate 101. A connector 501 fixedly connected to the connecting seat 102 is fixedly provided at the lower end of the pull belt 5. The connection seat 102 and the connector 501 can be fixedly connected, which makes it easy for the pull belt 5 to drive the aeration component 1 to move.

[0031] In an embodiment of this utility model, the winding mechanism 3 includes a frame body 301. A drive rod 302, a transmission rod 303, and a winding rod 305 are rotatably mounted on opposite sides of the frame body 301. A first gear set 304 meshes between the drive rod 302 and the transmission rod 303, and a second gear set 306 meshes between the transmission rod 303 and the winding rod 305. The first gear set 304 enables the drive rod 302 to rotate synchronously with the transmission rod 303, and the second gear set 306 facilitates the transmission rod 303 to drive the winding rod 305 to rotate synchronously, so that the winding rod 305 can control the rotation of the pull belt 5 to achieve the winding effect.

[0032] In an embodiment of this utility model, a circular plate 307 is fixedly provided on the outer wall of one end of the transmission rod 303, and a ratchet 308 is fixedly provided on the side of the circular plate 307. A fixing rod 309 is fixedly installed between the inner walls of the frame body 301 and above the drive rod 302. A pawl 310 that cooperates with the ratchet 308 is rotatably installed on the wall of the fixing rod 309. The ratchet 308 and the pawl 310 on the fixing rod 309 can achieve the effect of limiting the position, so that the winding rod 305 will not flip over during the winding of the belt 5, thus strengthening the fixation of the rotation position.

[0033] In an embodiment of this utility model, a connecting rod 311 is fixedly connected between two drive rods 302 on one side, and a drive motor 4 fixedly connected to the outer wall of the frame body 301 is fixedly installed at the side end of one drive rod 302; the two winding mechanisms 3 on the same side can be controlled to work synchronously under the drive of the drive motor 4 through the connection of the connecting rod 311.

[0034] In an embodiment of this utility model, a guide 6 is fixedly provided at the top of the treatment tank near the winding mechanism 3, and the outer wall of the pull belt 5 is in contact with the inner wall of the guide 6; the guide 6 can support the pull belt 5 and maintain good tension, so that the pull belt 5 can drive the aeration assembly 1 to move smoothly.

[0035] In an embodiment of this utility model, the guide member 6 includes two vertical plates 601. Two guide rods 602 that clamp the pull belt 5 are rotatably mounted on the two vertical plates 601. A support plate 603 that fits against the bottom side of the pull belt 5 is fixedly provided on one side of the two vertical plates 601 near the side end of the aeration component 1. A scraper 604 that fits against the top of the pull belt 5 is fixed between the two opposite sides of the support plate 603. The guide rods 602 can reduce the moving resistance of the pull belt 5. The support plate 603 can further support the pull belt 5. The scraper 604 can scrape the two sides of the pull belt 5 to remove the tailwater and impurities adsorbed on the surface of the pull belt 5.

[0036] In an embodiment of this utility model, the side end of the adapter pipe 202 is constructed with a connecting groove 204 that is connected to the side end of the connecting pipe 203, and an arc-shaped cover plate 205 that fits against the top of the connecting pipe 203 is fixedly installed on the top of the connecting groove 204; the combination connection between the arc-shaped cover plate 205 and the adapter pipe 202 allows for convenient separation and operation, and facilitates the independent movement of the connecting pipe 203.

[0037] Working Principle: This embodiment provides an aeration device for treating landfill leachate tailwater. In use, the connector 501 at the lower end of the pull belt 5 connects to the connecting seat 102 at the top of the fixed plate 101. The height of the aeration component 1 can be adjusted by controlling the length of the pull belt 5 using the winding mechanism 3. This allows the aeration component 1 to be lifted directly from the treatment tank by the winding mechanism 3 when cleaning or maintenance is needed. Moving it to the tank opening facilitates cleaning and maintenance. Before lifting the aeration component 1, the connecting groove 204 can be removed from the top of the transfer pipe 202, connecting the connecting pipe 203 to the transfer pipe 202. The side end is exposed, which can release the position limit of the aeration component 1 and facilitate movement. During the winding process of the pull belt 5, when the outer wall of the pull belt 5 passes the guide 6, it can scrape off the adsorbed tail water and adhering impurities, thereby maintaining the cleanliness of the winding. When the cleaning and maintenance are completed and the aeration component 1 needs to be put back into the bottom of the treatment tank, the pawl 310 can be pulled up first to separate it from the ratchet 308 and release the limit. Then, under the reverse rotation of the drive motor 4, the winding mechanism 3 can be reversed to put the wound pull belt 5 back, so that the aeration component 1 can be moved smoothly to the bottom of the treatment tank. The coordination of the overall structure can improve the convenience of cleaning and maintenance of the aeration component 1.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
