Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a deodorization device for wastewater treatment. Background Technology

[0002] Domestic sewage refers to wastewater generated by urban government offices, schools, and residents in their daily lives. It includes toilet waste, laundry and bathing water, kitchen wastewater, and wastewater from commercial establishments, hospitals, and amusement parks. The main pollutants in domestic sewage are ammonia nitrogen and suspended solids. These components easily produce malodorous substances under the action of anaerobic bacteria. These malodorous substances pose a significant threat to human health. Long-term inhalation of these malodorous gases may even cause diseases. Therefore, it is necessary to pay attention to the elimination of malodorous gases in domestic sewage.

[0003] While current domestic wastewater treatment systems employ deodorizers to eliminate odors, these systems generally suffer from insufficient mixing efficiency. This results in inadequate mixing of the deodorizer and wastewater, weakening the deodorization effect and slowing down treatment efficiency. More problematic is that even during mixing, odor leakage is difficult to completely prevent, impacting air quality and significantly reducing operator comfort and satisfaction.

[0004] Therefore, a deodorization device for wastewater treatment is needed to solve the above problems. Utility Model Content

[0029] Reference Figures 1-4 As one embodiment of this utility model, a deodorization device for sewage treatment is provided, which includes:

[0030] Main unit 100, including sewage treatment tank 101;

[0031] The deodorization mechanism 200 includes a fixed box 201 and a stirring assembly. The fixed box 201 is fixedly connected to the upper end of the sewage treatment tank 101. A straight cylinder 202, an activated carbon filter assembly 218, and a dustproof net 219 are fixedly installed on the inner wall of the fixed box 201. A servo motor 203 is fixedly connected to the side wall of the fixed box 201. The output end of the servo motor 203 passes through the side wall of the fixed box 201 and the straight cylinder 202 and is fixedly connected to a rotating shaft 204. A first bevel gear 205 is fixedly sleeved on the rotating shaft 204. Two second bevel gears 206 are meshed on the first bevel gear 205. A crossbar 207 is fixedly inserted at the center of each second bevel gear 206. The other end of each crossbar 207 is fixedly... A first bevel gear 208 is fixedly sleeved, and a second bevel gear 209 is meshed with each first bevel gear 208. A connecting shaft 210 is fixedly inserted at the center of each second bevel gear 209. A one-way blade 211 is fixedly connected to the upper end of each connecting shaft 210. The stirring assembly includes a third bevel gear 212, which meshes with the first bevel gear 205. A connecting rod 213 is fixedly inserted at the center of the third bevel gear 212. A small gear 214 is fixedly sleeved at the lower end of the connecting rod 213. A large gear 215 is meshed with the small gear 214. A vertical rod 216 is fixedly inserted at the center of the large gear 215. Multiple stirring blades 217 are fixedly connected at equal intervals on the side wall of the vertical rod 216.

[0032] The servo motor 203, rotating shaft 204, and first bevel gear 205 drive the second bevel gear 206 and third bevel gear 212 to rotate. The third bevel gear 212, connecting rod 213, and small gear 214 drive the large gear 215 to rotate. The large gear 215 drives the vertical rod 216 and stirring blade 217 to rotate. Multiple stirring blades 217 stir the sewage, making the sewage and deodorizing agent mix quickly and evenly, improving the deodorization effect and treatment efficiency. The arrangement of the first bevel gear 205, second bevel gear 206, and horizontal rod 207 drives the first cone... The rotation of gear 208 drives the rotation of two one-way blades 211 through the arrangement of bevel gear 208, bevel gear 209 and connecting shaft 210. Since the two one-way blades 211 are installed in opposite directions, air is drawn in through the dustproof net 219 and blown into the sewage treatment tank 101. The gas inside the sewage treatment tank 101 is discharged after being adsorbed by the activated carbon filter component 218. The activated carbon filter component 218 further removes odors, improves the air quality of the surrounding environment, and improves the working comfort and satisfaction of the operators.

[0033] One end of each of the two crossbars 207 passes through the side wall of the straight cylinder 202 and is rotatably connected to the inner wall of the straight cylinder 202. The lower ends of the two connecting shafts 210 are rotatably connected to the inner wall of the fixed box 201. The fixed box 201 is connected to the inside of the sewage treatment box 101 through multiple through holes, and the unidirectional blades 211 are driven to rotate through the connecting shafts 210.

[0034] One end of the connecting rod 213 passes through the straight cylinder 202, the fixed box 201 and the sewage treatment box 101 and is rotatably connected to the inner wall of the straight cylinder 202, the fixed box 201 and the sewage treatment box 101. The connecting rod 213 drives the pinion 214 to rotate.

[0035] The gear ratio between the multiple large gears 215 and the small gears 214 is 3:1. The two ends of the multiple vertical rods 216 are rotatably connected to the inner wall of the sewage treatment tank 101, and the large gears 215 are driven to rotate by the small gears 214.

[0036] The upper end of the sewage treatment tank 101 is fixedly connected to an inlet pipe 103, and a drain pipe 102 is fixedly connected to one side of the sewage treatment tank 101. A valve is installed on the drain pipe 102, and sewage enters the sewage treatment tank 101 through the inlet pipe 103.

[0037] The wastewater treatment tank 101 is fixedly connected to a feeding pipe at its upper end, and a cover is slidably fitted onto the upper end of the feeding pipe to release deodorizing agent.

[0038] Working principle: Wastewater enters the wastewater treatment tank 101 through the inlet pipe 103. Deodorant is added through the feeding pipe. The servo motor 203 is started, which drives the rotating shaft 204. The rotating shaft 204 drives the first bevel gear 205 to rotate. The first bevel gear 205 drives the third bevel gear 212 to rotate. The third bevel gear 212 drives the connecting rod 213 to rotate. The connecting rod 213 drives the small gear 214 to rotate. The small gear 214 drives the large gear 215 to rotate. The large gear 215 drives the vertical rod 216 and the stirring blade 217 to rotate. The stirring blade 217 stirs the wastewater, making the wastewater and deodorant mix quickly and evenly, improving the deodorization effect and treatment efficiency.

[0039] Furthermore, the first bevel gear 205 drives the second bevel gear 206 to rotate, which in turn drives the crossbar 207 to rotate. The crossbar 207 then drives the first bevel gear 208 to rotate, which in turn drives the second bevel gear 209 to rotate. The second bevel gear 209 then drives the connecting shaft 210 to rotate, which in turn drives the two one-way blades 211 to rotate. Since the two one-way blades 211 are installed in opposite directions, air is drawn in through the dustproof net 219 and blown into the sewage treatment tank 101. The gas inside the sewage treatment tank 101 is then discharged after being adsorbed and treated by the activated carbon filter assembly 218. The activated carbon filter assembly 218 further removes odors, improving the air quality of the surrounding environment and increasing the comfort and satisfaction of the operators. The contents not described in detail in this description are existing technologies known to those skilled in the art.
