Description

Technical Field

[0001] This utility model relates to the field of odor collection technology, specifically to an odor collection device for sewage ponds. Background Technology

[0002] With the completion of the sewage treatment plant, the operating sewage treatment plant will generate a large amount of malodorous gas, which will not only affect the health and working environment of the sewage treatment plant employees, but also cause serious harm to the surrounding investment environment and the daily lives of residents.

[0003] In wastewater treatment, to prevent odors from escaping from wastewater tanks and improve odor collection efficiency, existing technologies typically employ a fully sealed tank cover, with odor extraction achieved via a pipe connected to the inside of the cover. However, given the generally large volume of current wastewater tanks, this single-point extraction method has significant drawbacks. The collection rate is extremely slow, making it difficult to efficiently and comprehensively collect the diffused odors within the wastewater tank. This results in a large accumulation of odors within the tank, which cannot be promptly discharged and subsequently treated.

[0004] Therefore, it is necessary to provide a sewage odor collection device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a sewage tank odor collection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sewage odor collection device, comprising:

[0008] The sewage tank has a tank cover fixedly installed on its top, a cover plate fixedly installed on the top of the tank cover, several fixing brackets fixedly installed on the inner surface of the tank cover, a U-shaped tube fixedly installed on the tank cover through the fixing brackets, and several collection pipes fixedly installed at equal intervals and evenly on the lower side of the outer wall of the U-shaped tube.

[0009] An external drain pipe is fixedly installed on the front of the pool cover, and one end of the external drain pipe passes through the pool cover and extends into the interior of the pool cover and is fixedly connected to a U-shaped pipe. A centrifugal fan is fixedly installed on the front of the pool cover, and the input end of the centrifugal fan is fixedly connected to the other end of the external drain pipe. An external pipe is fixedly connected to the output end of the centrifugal fan. A sensor module is provided on one side inside the pool cover.

[0010] Preferably, an inspection port is provided on one side of the top of the cover plate, and a movable sealing plate adapted to it is hinged to the inspection port. A latch is provided at the connection between the movable sealing plate and the top of the cover plate, and a handle is fixedly installed on the outer surface of the movable sealing plate.

[0011] Preferably, a ladder is fixedly installed on the bottom of the cover plate on one side of the access port, and symmetrically distributed reinforcing rods are welded between the ladder and the bottom of the cover plate.

[0012] Preferably, a stirring shaft is rotatably mounted on the bottom of the cover plate, a plurality of stirring blades are fixedly mounted on the outer wall of the stirring shaft, a servo motor is fixedly mounted on the top of the cover plate, and the drive end of the servo motor passes through the cover plate and is fixedly connected to the top end of the stirring shaft, and a plurality of pressure relief holes are provided on the stirring blades.

[0013] Preferably, a sealing gasket is provided on the top of the sewage tank.

[0014] Preferably, the sensor module includes an electrochemical sensor, a metal oxide semiconductor sensor, a photoionization sensor, and an infrared sensor.

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

[0016] 1. This utility model utilizes the combined use of a sewage tank, tank cover, cover plate, external discharge pipe, centrifugal fan, external connecting pipe, sensor module, U-shaped pipe, fixing frame, and collection pipe. Throughout the odor collection process, the U-shaped pipe is laid along the inner surface of the tank cover, and the collection pipe is used inside the tank cover to collect odors generated by sewage within the sewage tank at multiple points. This method significantly improves odor collection efficiency. Simultaneously, the sensor module enables real-time monitoring of the odor content inside the sewage tank, allowing staff to accurately track the progress of odor collection.

[0017] 2. This utility model, through the combined use of an inspection port, ladder, movable sealing plate, and handle, allows workers to open the movable sealing plate on the top of the cover after the treated sewage in the sewage tank has been discharged during the operation of the sewage tank. They can then enter the sewage tank through the inspection port and with the help of the ladder. This operation facilitates the workers to carry out inspection and maintenance work on the inside of the sewage tank, thereby ensuring that the device can continue to operate normally.

[0018] 3. This invention utilizes a servo motor, stirring blades, a stirring shaft, and a pressure relief hole. During wastewater treatment, when a purifying agent is added, the servo motor is activated, and its drive end rotates the stirring shaft and stirring blades, agitating the wastewater in the wastewater tank. This ensures sufficient and uniform contact between the wastewater and the purifying agent, providing more opportunities for reaction between the purifying agent and pollutants. This allows for more comprehensive and effective removal of pollutants from the wastewater, ensuring that the purified water meets the required standards. Attached Figure Description

An external pipe 11 is fixedly connected to the output end of the centrifugal fan 10. A sensor module 12 is provided on one side inside the pool cover 2.

[0032] A maintenance opening 4 is provided on one side of the top of the cover plate 3. A movable sealing plate 6 that matches the maintenance opening 4 is hinged to the maintenance opening 4. A latch is provided at the connection between the movable sealing plate 6 and the top of the cover plate 3. A handle 7 is fixedly installed on the outer surface of the movable sealing plate 6.

[0033] In one embodiment, a ladder 5 is fixedly installed on the bottom of the cover plate 3 on one side of the access port 4. Symmetrically distributed reinforcing rods 19 are welded between the ladder 5 and the bottom of the cover plate 3. The reinforcing rods 19 are welded to reinforce the connection between the ladder 5 and the cover plate 3 to ensure safe use.

[0034] In one preferred embodiment, a stirring shaft 18 is rotatably mounted on the bottom of the cover plate 3, and several stirring blades 17 are fixedly mounted on the outer wall of the stirring shaft 18. A servo motor 8 is fixedly mounted on the top of the cover plate 3, and the drive end of the servo motor 8 passes through the cover plate 3 and is fixedly connected to the top end of the stirring shaft 18. Several pressure relief holes 20 are provided on the stirring blades 17. The pressure relief holes 20 can reduce stirring resistance, reduce energy consumption and equipment wear, make stirring more stable, and enhance the mixing effect of purifying agent and sewage.

[0035] In one embodiment, a sealing gasket 16 is provided on the top of the sewage tank 1 to prevent odor from escaping, avoid environmental pollution, reduce sewage evaporation, and ensure treatment effect.

[0036] In one preferred embodiment, the sensor module 12 includes an electrochemical sensor, a metal oxide semiconductor sensor, a photoionization sensor, and an infrared sensor. The combination of multiple sensors enables the sensor module 12 to detect odors from different principles, accurately and sensitively detect odors of various components and concentration ranges, and can work stably in complex environments, thereby improving detection accuracy and reliability and providing data for odor collection.

[0037] The working principle of this utility model is as follows: All electrical components mentioned herein are connected to an external main controller and 220V AC mains power. The main controller can be a computer or other conventionally known control device. Parts not mentioned in this device are the same as or can be implemented using existing technology. When the device is put into use, the centrifugal fan 10 is started to enter working condition. At this time, the odor generated by the sewage in the sewage tank 1 is drawn into the U-shaped pipe 13 through the collection pipe 15, then extracted through the external discharge pipe 9, and then transported to the external deodorization equipment for further treatment via the external pipe 11. Throughout the odor collection process, the U-shaped pipe 13 is laid along the inner surface of the tank cover 2. The collection pipe 15 is used to collect the odor generated by the sewage in the sewage tank 1 from multiple points inside the tank cover 2. This method significantly improves the odor collection efficiency. Simultaneously, the sensor module 12 is used to monitor the odor content inside the sewage tank 1 in real time, allowing staff to accurately track the progress of odor collection.

[0038] During the operation and use of the sewage tank 1, after the treated sewage in the sewage tank 1 has been discharged, the staff can open the movable sealing plate 6 on the top of the cover plate 3, enter the sewage tank 1 through the inspection port 4 and with the help of the ladder 5. This operation facilitates the staff to carry out inspection and maintenance work on the inside of the sewage tank 1, thereby ensuring that the device can continue to operate normally.

[0039] In wastewater treatment, various purifying agents are typically added to purify the wastewater. To ensure sufficient and uniform contact between the purifying agent and the wastewater, a servo motor 8 can be activated. The servo motor 8 drives the stirring shaft 18 to rotate, which in turn drives the stirring blades 17 to rotate. The rotation of the stirring blades 17 stirs the wastewater in the wastewater tank 1, promoting thorough mixing and contact between the wastewater and the purifying agent. This thorough contact provides more opportunities for the purifying agent to react with various pollutants in the wastewater, thereby more comprehensively and effectively removing pollutants from the wastewater and ensuring that the purified water quality meets the prescribed standards.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
