Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment deodorization devices, in particular to a deodorization device for a sewage treatment pool. Background Art

[0002] A sewage treatment tank is a facility used to treat domestic sewage and industrial wastewater. Its purpose is to improve water quality and the environment. According to the structural type, sewage treatment tanks can be divided into above-ground and underground types. The above-ground type is generally made of welded steel structure, while the underground type is mostly made of concrete structure or masonry structure.

[0003] The working principle of a sewage treatment tank usually includes pretreatment, primary treatment, secondary treatment, tertiary treatment and disinfection. The pretreatment stage mainly removes large suspended particles, sediment, grease, etc. in the wastewater to reduce the burden of subsequent treatment processes and protect equipment from damage. The primary treatment stage mainly removes suspended particles and a portion of dissolved organic matter. The secondary treatment stage removes organic pollutants in the wastewater through biological treatment. The tertiary treatment stage generally uses sedimentation tanks and biofilm reactors to further remove residual suspended particles and sludge.

[0004] Various foul-smelling gases, such as hydrogen sulfide and ammonia, will be produced during the sewage treatment process. These gases not only have a bad smell, but may also be harmful to the health of the staff. Working in such an environment for a long time may cause discomfort symptoms such as dizziness, nausea, vomiting, and even affect work efficiency. If the foul-smelling gases in the sewage treatment pool are directly discharged into the atmosphere without treatment, it will pollute the surrounding environment and affect the quality of life of residents. At the same time, these gases may also react chemically with other atmospheric pollutants to form secondary pollution. Therefore, a deodorization device is needed in the sewage treatment pool to treat it. Through the treatment of the deodorization device, the emission of odorous gases can be reduced and the pollution to the environment can be reduced.

[0005] However, some deodorization devices, such as activated carbon adsorption devices, although the deodorization effect is good, the activated carbon needs to be replaced regularly, resulting in increased operating costs. In addition, some devices require a lot of energy consumption, which also increases operating costs. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a deodorization device for a sewage treatment pool to solve the technical problems that some deodorization devices, such as activated carbon adsorption devices, have good deodorization effects, but the activated carbon needs to be replaced regularly, resulting in increased operating costs. In addition, some devices require a large amount of energy consumption, which also increases operating costs.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deodorizing device for a sewage treatment pool comprises a treatment barrel, a rotating plate is rotatably connected in the treatment barrel, a deodorizing layer is arranged above the rotating plate, the deodorizing layer is composed of activated carbon and quartz sand materials, a contraction rod is fixedly installed on the inner side of the rotating plate in a symmetrical structure, a movable block is fixedly connected to the end of the contraction rod, a motor is fixedly installed on the outer side of the treatment barrel, a transmission rod is fixedly connected to the output end of the motor, one end of the transmission rod is fixedly connected to the rotating plate, a discharge block is arranged at the bottom of the treatment barrel, a drain pipe is provided on one side of the treatment barrel, the drain pipe is located below the motor, a top cover is fixedly connected to the top of the treatment barrel, a water inlet pipe is provided on the top cover, a liquid guide ring is fixedly connected to the top of the top cover, a connecting pipe is fixedly connected between the liquid guide rings, a plurality of groups of nozzles are fixedly installed on the connecting pipe and the bottom of the liquid guide ring, a liquid inlet pipe is provided on the top of the connecting pipe, and the liquid inlet pipe passes through the top cover.

When the sewage is stored in the treatment barrel, the malodorous gas in the sewage can be further treated by the deodorizing layer composed of activated carbon and quartz sand materials.

At the same time, when the deodorizing layer needs to be replaced, the retracting rod is retracted into the rotating plate through an external power supply, so that the movable block is retracted into the rotating plate, and then the transmission rod is driven by the motor to rotate, driving the rotating plate to rotate clockwise. The needle rotates 180°, so that the deodorizing layer enters the discharge block, and then the discharge block is separated from the processing barrel. When the discharge block is separated from the processing barrel, the deodorizing layer in the discharge block is further processed. When a new deodorizing layer needs to be replaced, the motor drives the transmission rod to reverse, so that the rotating plate rotates 180° counterclockwise in the processing barrel, and then the retracting rod is extended through an external power supply, so that the movable block extends from the rotating plate and is stuck in the processing barrel, thereby achieving the effect of fixing the rotating plate. Finally, the deodorizing layer can be reintroduced into the processing barrel through the water inlet pipe. This structure is used to solve the problem that the deodorizing device in the prior art cannot be well replaced with a new activated carbon adsorption device and is inconvenient to use, thereby improving the practicality and working efficiency of the deodorizing device of the entire sewage treatment tank.

[0012] By adopting the above technical solution, the limiting ring is set in the installation groove to facilitate the buckling of the adsorption plate inside the treatment barrel to deodorize the sewage.

The card slot is set to cooperate with the movable block to fix the rotating plate in the processing barrel for use. Secondly, through the protective shell, the motor can be supported and fixed, and the effect of noise reduction and shock absorption can be achieved.

[0020] By adopting the above technical scheme, the rotating connecting part and the lock buckle cooperate with each other so that the sealing door can be opened and closed on the processing barrel. When the sealing door is a semi-arc structure, the sealing door can fit more closely with the processing barrel to avoid water leakage. The grooves are used to facilitate the flexible replacement of the adsorption plate so that the entire deodorization device can be used continuously.

Finally, the rotating connector 5 and the lock buckle 7 are provided. The sealing door 6 cooperates with each other so that the sealing door 6 can be opened and closed on the treatment barrel 1. When the sealing door 6 is a semi-arc structure, the sealing door 6 can fit more closely with the treatment barrel 1 to avoid water leakage. The groove 28 is used to flexibly replace the adsorption plate 20 so that the entire deodorization device can be used continuously. When the adsorption plate 20 needs to be taken out of the treatment barrel 1, the adsorption plate 20 is lifted up from the limiting ring 19, and the adsorption plate 20 is rotated so that the adsorption plate 20 is taken out from the groove 28 at an inclined angle.
