Description

Technical Field

[0001] This utility model relates to the field of sewage well deodorization technology, and in particular to an activated carbon deodorization device for sewage wells. Background Technology

[0002] With the rapid development of urban construction in my country, sewage wells have become an indispensable and important facility in urban drainage systems. Typically constructed of reinforced concrete, brick, and other materials, they are installed at a certain depth underground to collect and gather domestic sewage, industrial wastewater, and rainwater runoff from residential, commercial, and industrial areas. Internal pipes guide the orderly flow of sewage, facilitating its subsequent transport to sewage treatment plants for centralized purification. Because sewage wells often contain large amounts of organic pollutants and odorous substances, which produce foul-smelling gases during volatilization, severely impacting the surrounding environment and air quality, activated carbon deodorization devices are necessary.

[0003] A search revealed Chinese patent publication number CN218608711U, which discloses an activated carbon deodorization device for sewage wells. The device includes a canister-shaped shell with an internal installation space, a water trap on the outer bottom, an air inlet at the center of the bottom, a water inlet on the outer top, and a mounting groove at the center of the top. The activated carbon deodorization device includes an odor collection box and a cover. The odor collection box contains multiple layers of activated carbon filters, and the cover has fixing holes. The sewage well activated carbon deodorization device is made of steel, providing high overall strength. Its canister-shaped shell structure provides protection and prevents accidents. The device effectively deodorizes malodorous gases emitted from sewage wells. The multiple activated carbon filters prevent the sewage well from emitting foul odors. Furthermore, the device's internal structure is rationally designed; as an independent unit, it can be removed separately for easy replacement of the activated carbon filter element.

[0004] In the aforementioned utility model, a can-shaped shell is placed at the opening of a sewage well. Holes and slots are opened at the bottom and top of the can-shaped shell to circulate and ventilate the sewage well. A collection box is installed at the holes and slots, and the activated carbon filter layer inside the collection box is used for deodorization. However, in actual use, when maintaining and replacing the activated carbon filter layer, the entire odor collection box needs to be disassembled, which makes it inconvenient to adjust the activated carbon filter layer and the process is time-consuming and labor-intensive. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an activated carbon deodorization device for sewage wells, which aims to improve the problems of inconvenience and time-consuming and labor-intensive process when adjusting the activated carbon filter layer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An activated carbon deodorization device for sewage wells includes a fixed sleeve with a cover plate on its inner wall. An activated carbon filter sleeve is disposed inside the fixed sleeve. A slider is fixedly connected to the outer wall of the activated carbon filter sleeve, and the outer wall of the slider is slidably connected to the inside of the fixed sleeve. A circular block is fixedly connected to the upper surface of the activated carbon filter sleeve. A sliding rod is slidably connected inside the circular block. An I-shaped sleeve is slidably connected to the outer wall of the sliding rod. A second circular block is disposed on the outer wall of the I-shaped sleeve. The lower surface of the second circular block is fixedly connected to the upper surface of the activated carbon filter sleeve. A spring is fixedly connected to the outer wall of the I-shaped sleeve. A transmission frame is fixedly connected to the outer wall of the spring. The inner wall of the transmission frame is fixedly connected to the outer wall of the sliding rod. An L-shaped rod is fixedly connected to the upper surface of the activated carbon filter sleeve. An air inlet assembly is disposed on the lower surface of the fixed sleeve.

[0008] The above technical solution utilizes a sliding rod that slides in and out of the fixed sleeve to limit or release the activated carbon filter sleeve. A slider also slides within the fixed sleeve to limit the activated carbon filter sleeve, preventing it from shifting due to external influences and affecting its filtration function. The activated carbon filter sleeve is filled with activated carbon to filter odors from the sewage well, thus achieving deodorization. A handheld transmission frame moves the sliding rod. When the transmission frame reaches its rightmost position, it is pulled back to limit the transmission frame with an L-shaped rod, thus avoiding the need for the operator to continuously hold the transmission frame.

[0009] As a further description of the above technical solution:

[0010] The air intake assembly includes an air intake chamber, the upper surface of which is fixedly connected to the lower surface of the fixed sleeve, and an air intake plate is fixedly connected inside the air intake chamber.

[0011] The above technical solution allows the odor from the sewage well to be buffered in the air inlet chamber to prevent the odor from directly impacting the deodorizing part of the device, and then pass through the air inlet plate so that the odor can move upward more smoothly.

[0012] As a further description of the above technical solution:

[0013] The cover plate has an air vent inside, and a fixing block is fixedly connected to the lower surface of the cover plate.

[0014] The above technical solution involves using an air outlet to discharge the deodorized gas from the device, and using a cover plate to fix the fixing block.

[0015] As a further description of the above technical solution:

[0016] The fixing block is internally slidably connected to a connecting rod, and the outer wall of the fixing block is slidably connected to the inner wall of the fixing sleeve.

[0017] The above technical solution utilizes the fit between the fixing block and the fixing sleeve to facilitate the movement of the internal structure of the fixing block, thereby limiting the positioning of the fixing block.

[0018] As a further description of the above technical solution:

[0019] A handle is fixedly connected to the outer wall of the connecting rod, and a semi-circular block is fixedly connected to the outer wall of the connecting rod.

[0020] The above technical solution utilizes a handle to facilitate the operation of the connecting rod, thereby driving the semicircular block.

[0021] As a further description of the above technical solution:

[0022] A second spring is fixedly connected to the outer wall of the semicircular block, and a fixing plate is fixedly connected to the outer wall of the second spring.

[0023] Through the above technical solution: when the semicircular block moves, under the action of the fixed plate, the semicircular block compresses the second spring, and conversely, the second spring pushes against the semicircular block to move.

[0024] As a further description of the above technical solution:

[0025] The outer wall of the fixing plate is fixedly connected to the inside of the fixing block, and the inside of the fixing plate is slidably connected to the outer wall of the connecting rod.

[0026] The above technical solution involves fixing the fixing plate with a fixing block, and supporting the movement of the connecting rod through the interior of the fixing block and the fixing plate.

[0027] As a further description of the above technical solution:

[0028] The outer wall of the semicircular block is slidably connected to the inside of the fixed block, and the outer wall of the semicircular block is slidably connected to the inside of the fixed sleeve.

[0029] The above technical solution utilizes a semicircular block that moves within a fixed block and a fixed sleeve. The surface of the semicircular block is smooth, allowing it to slide into the fixed sleeve, thereby limiting the semicircular block's position.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the installation and disassembly of the activated carbon filter sleeve are simplified by the cooperation between the first round block, the slide rod, the transmission frame, the I-shaped sleeve, the second round block, the first spring, the L-shaped rod and the slider. The type and specifications of activated carbon can be flexibly adjusted, thereby improving the deodorization efficiency of the device. At the same time, it is convenient to replace the activated carbon and reduce the risk of deodorization being affected by the blockage or failure of activated carbon.

[0032] 2. In this utility model, through the cooperation between the fixing block, handle, connecting rod, fixing plate, spring two and semi-circular block, without complicated operation and tools, the staff can quickly complete the installation and disassembly of the cover plate, which is convenient for maintenance and repair, and also improves the emergency handling capability of the device.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1-3An embodiment of this utility model provides an activated carbon deodorization device for sewage wells, comprising a fixed sleeve 1, a cover plate 2 provided on the inner wall of the fixed sleeve 1, an activated carbon filter sleeve 5 provided inside the fixed sleeve 1, a slider 6 fixedly connected to the outer wall of the activated carbon filter sleeve 5, the outer wall of the slider 6 slidably connected to the inside of the fixed sleeve 1, a circular block 7 fixedly connected to the upper surface of the activated carbon filter sleeve 5, a sliding rod 8 slidably connected inside the circular block 7, an I-shaped sleeve 10 slidably connected to the outer wall of the sliding rod 8, a circular block 11 provided on the outer wall of the I-shaped sleeve 10, the lower surface of the circular block 11 fixedly connected to the upper surface of the activated carbon filter sleeve 5, a spring 12 fixedly connected to the outer wall of the I-shaped sleeve 10, a transmission frame 9 fixedly connected to the outer wall of the spring 12, the inner surface of the transmission frame 9 fixedly connected to the outer wall of the sliding rod 8, an L-shaped rod 13 fixedly connected to the upper surface of the activated carbon filter sleeve 5, and an air inlet assembly 4 provided on the lower surface of the fixed sleeve 1.

[0041] Specifically, the activated carbon inside the activated carbon filter sleeve 5 is used to deodorize the odor from the drainage well. The activated carbon filter sleeve 5 fixes the circular blocks 7 and 11, while the circular block 7 limits the movement of the sliding rod 8, and the circular block 11 limits the movement of the I-shaped sleeve 10, thus limiting the sliding rod 8. The I-shaped sleeve 10 can move inside the circular block 11, facilitating the operation of the spring 12 by the transmission frame 9 to squeeze or rotate. The fixed sleeve 1 has multiple grooves inside, which facilitates the installation of multiple activated carbon filter sleeves 5 and the adjustment of the distance between the activated carbon filter sleeves 5, thereby improving the overall deodorization efficiency of the device. The L-shaped rod 13 is used to limit the rotation of the transmission frame 9, avoiding the need to continuously press the transmission frame 9. The slider 6 is used to assist in the installation of the activated carbon filter sleeve 5 and to prevent the activated carbon filter sleeve 5 from shaking due to instability after installation. The fixed sleeve 1 is made of metal to enhance the overall strength of the device.

[0042] Reference Figure 3 The air intake assembly 4 includes an air intake chamber 401, the upper surface of which is fixedly connected to the lower surface of the fixed sleeve 1, and an air intake plate 402 is fixedly connected inside the air intake chamber 401.

[0043] Specifically, the air intake chamber 401 is used as a buffer chamber, and the chamber is made of metal. After the odor enters the air intake chamber 401 through the holes in the air intake plate 402, the flow rate will be reduced and the gas will be evenly distributed, thereby improving the adsorption efficiency of activated carbon.

[0044] Reference Figure 1 The cover plate 2 has an air vent 3 inside, and a fixing block 14 is fixedly connected to the lower surface of the cover plate 2.

[0045] Specifically, the cover plate 2 is made of metal to strengthen its support, and the cover plate 2 has multiple holes and grooves arranged in a certain regular pattern to facilitate the exhaust of air after deodorization.

[0046] Reference Figure 4 The fixing block 14 is internally slidably connected to a connecting rod 16, and the outer wall of the fixing block 14 is slidably connected to the inner wall of the fixing sleeve 1. The outer wall of the connecting rod 16 is fixedly connected to a handle 15, and the outer wall of the connecting rod 16 is fixedly connected to a semi-circular block 19. The outer wall of the semi-circular block 19 is fixedly connected to a second spring 18, and the outer wall of the second spring 18 is fixedly connected to a fixing plate 17. The outer wall of the fixing plate 17 is fixedly connected to the inside of the fixing block 14, and the inside of the fixing plate 17 is slidably connected to the outer wall of the connecting rod 16. The outer wall of the semi-circular block 19 is slidably connected to the inside of the fixing block 14, and the outer wall of the semi-circular block 19 is slidably connected to the inside of the fixing sleeve 1.

[0047] Specifically, the connecting rod 16 and the fixing block 14 are used to support the movement of the semicircular block 19, and also to limit the range of the semicircular block 19. The fixing plate 17 and the fixing block 14 both support and limit the movement of the connecting rod 16. Without the action of the handle 15, the elastic force of the spring 18 is used to push the semicircular block 19 into the interior of the fixing sleeve 1, thereby limiting the cover plate 2 and improving the stability of the cover plate 2 installation.

[0048] Working principle: When using this device, pull the transmission frame 9, which will move the slide bar 8 to the right and compress the spring 12. When the transmission frame 9 moves to the right side of the L-shaped rod 13, pull the transmission frame 9 backward to make the spring 12 and the I-shaped sleeve 10 rotate backward, avoiding the need to continuously operate the transmission frame 9. Then release the transmission frame 9. The L-shaped rod 13 will limit the transmission frame 9, moving the activated carbon filter sleeve 5 and the slider 6 along the inside of the fixed sleeve 1. Adjust the position of the activated carbon filter sleeve 5 inside the fixed sleeve 1 according to the usage requirements. After adjustment, pull the transmission frame 9 to the right and move it to the right side of the L-shaped rod 13. Pull the transmission frame 9 forward and then release the transmission frame 9. Under the elastic force of the spring 12, the slide bar 8 will slide into the inside of the fixed sleeve 1, thereby quickly installing and disassembling the activated carbon filter sleeve 5. Finally, fix the fixed sleeve 1 to the opening of the sewage well and use the air intake component 4 to improve the uniformity of odor treatment.

[0049] When maintenance of the activated carbon filter sleeve 5 is required, the operator's hand reaches into the inside of the cover plate 2, holds the handle 15, and drives the connecting rod 16 to move to the right, thereby causing the semi-circular block 19 to move to the right inside the fixed plate 17 and slide out of the fixed sleeve 1, compressing the spring 18. By pressing the cover plate 2 with the operator's hand and pulling the handle 15, the cover plate 2 is slid out of the inner wall of the fixed sleeve 1, and then the cover plate 2 can be disassembled to facilitate the inspection or maintenance of the components inside the fixed sleeve 1.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
