Description

Technical Field

[0001] The utility model relates to the technical field of deodorizing fans, in particular to a deodorizing fan used in a sewage treatment plant. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. During the process of sewage treatment by biochemical and aeration methods, a large amount of odor will be generated in the sewage anti-odor treatment pool. It is usually necessary to treat the generated odor to avoid affecting the surrounding residents.

[0003] An existing deodorizing blower for a sewage treatment plant (publication number: CN219128768U) has at least the following disadvantages: the device filters the air by setting four filter screens to improve the deodorizing effect. The staff pulls the filter screen out of the filter box and replaces it, so that the pulling filter screen can maintain a long-term filtering effect. However, since the amount of odor pollutants in the air is constant during the sewage treatment process, the filtering effect of the filter screen of the device is constantly attenuated, which will cause the filtering effect of the odor to become worse and worse, resulting in uneven filtering effects. At the same time, it will also cause the filter screen to be replaced too frequently, wasting manpower and material resources. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a deodorizing fan for a sewage treatment plant.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A deodorizing fan for a sewage treatment plant comprises a deodorizing channel. Mounting covers are installed at the openings on both sides of the deodorizing channel by bolts. Fan brackets are arranged in the two mounting covers. Motors 1 are installed on the two fan brackets. The rotating shafts of the two motors 1 pass through the fan brackets and are coaxially connected to fans. The two fans rotate in the same direction. A deodorizing assembly is installed in the middle of the deodorizing channel. The deodorizing assembly comprises a lifting shell and a filter mesh roll installed in the lifting shell.

[0007] As a further solution of the utility model, a plug-in groove is opened in the middle of the top surface of the deodorization channel, two through grooves are symmetrically opened on the left and right side walls of the deodorization channel just below the plug-in groove, and two mounting seats are symmetrically provided on the bottom surface of the deodorization channel just below the two through grooves.

[0008] As a further solution of the utility model, the pulling shell includes a connecting plate, and two storage barrels are symmetrically installed at both ends of the connecting plate.

Motors 4 are installed on the two fan brackets 31. The rotating shafts of the two motors 4 pass through the fan brackets 31 and are coaxially connected to fans 5. The two fans 5 rotate in the same direction. A deodorizing component 6 is installed in the middle of the deodorizing channel 1. The deodorizing component 6 comprises a lifting shell 61 and a filter screen roll 64 installed in the lifting shell 61.

[0023] In this embodiment, a plug-in groove 11 is provided in the middle of the top surface of the deodorizing channel 1, two through grooves 12 are symmetrically provided on the left and right side walls of the deodorizing channel 1 just below the plug-in groove 11, and two mounting seats 13 are symmetrically provided on the bottom surface of the deodorizing channel 1 just below the two through grooves 12.

[0024] In this embodiment, two storage barrels 612 are symmetrically installed at both ends of the connecting plate 611. A through groove 613 is respectively opened on the opposite sides of the outer walls of the two storage barrels 612. The bottom surfaces of the two storage barrels 612 are respectively abutted against the top surfaces of the two mounting seats 13. The connecting plate 611 is plug-in-fittedly connected with the plug-in groove 11, and the sizes of the through groove 12 and the through groove 613 are adapted to each other.

[0025] In this embodiment, a driving shaft 61 and a driven shaft 62 are rotatably connected in the two storage barrels 612 respectively, and a filter mesh roll 64 is wound and installed on the driving shaft 61 and the driven shaft 62. A number of activated carbon particles are evenly distributed on the surface of the filter mesh roll 64. The activated carbon particles can effectively absorb harmful impurities and play a role in purifying the gas.

[0026] In this embodiment, the top end of the driving shaft 61 passes through the storage barrel 612 and is coaxially connected to a driven gear 65. The connecting plate 611 is provided with a mounting arm 614 on one side of the driven gear 65. The mounting arm 614 is rotatably connected to a driving gear 66. The driving gear 66 is meshed and transmission-connected with the driven gear 65.

[0028] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: the staff first holds the handle 615 to pull the lifting shell 61 out of the deodorizing passage 1, and then fixes the filter mesh roll 64 coaxially with the driven rotating shaft 62 and loads it into the right storage barrel 612, and passes one end of the filter mesh roll 64 through the through slot 2 613 of the right storage barrel 612 and the through slot 2 613 of the left storage barrel 612, and then winds and fixes it on the active rotating shaft 61, and installs the deodorizing component 6 in the middle of the deodorizing passage 1, the connecting plate 611 is plugged and connected with the plug-in groove 11, the flattened part of the filter mesh roll 64 is plugged into the two through slots 12, and the bottom surfaces of the two storage barrels 612 are respectively abutted against the top surfaces of the two mounting seats 13, and the installation is completed;

[0029] Start two motors 1 4 to drive two fans 5 to rotate in the same direction, one fan 5 draws external air into the deodorizing passage 1, and the other fan 5 discharges the air filtered by the activated carbon filter from the deodorizing passage 1. After the fans 5 have worked for a certain period of time, start motor 2 67. Motor 2 67 drives the driving gear 66 to rotate, thereby indirectly driving the driven gear 65 to rotate. The driven gear 65 drives the driving shaft 61 to rotate. The driving shaft 61 rolls the used filter mesh roll 64 into the left storage barrel 612, and the driven shaft 62 rotates accordingly. A new filter mesh roll 64 enters the deodorizing passage 1 to continue working, and motor 2 67 stops working. This cycle repeats until the filter mesh roll 64 in the right storage barrel 612 is used up and replaced with a new filter mesh roll 64. At this point, the mechanical work is completed.
