Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a deodorizing device and method for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a 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, catering, etc., and is increasingly entering the daily lives of ordinary people. When sewage is treated, it will emit a bad smell, and the staff will easily cause damage to their bodies if they inhale the bad smell of sewage for a long time. Therefore, in the sewage treatment process, a deodorizing device is needed to deodorize the sewage.

[0003] Existing deodorization methods usually rely on manual operation or specific spraying devices to apply deodorants to the surface of sewage. However, there will be a large amount of oil on the surface of sewage, which will wrap the deodorant, causing the deodorant to remain on the surface of the sewage and difficult to quickly penetrate into the sewage, resulting in the deodorant and sewage being unable to be evenly mixed, greatly weakening the deodorization efficiency of the deodorant. In addition, given the vast internal space of the treatment device, the effect of mixing relying solely on the stirring shaft is not ideal, and there are still problems of slow mixing speed and uneven dispersion, which further reduces the overall deodorization effect. Summary of the invention

[0018] As a preferred embodiment of the deodorizing device for sewage treatment described in the present invention, three groups of supporting legs are installed at the bottom end of the treatment tank, and rubber pads are installed at the bottom ends of the supporting legs.

[0019] The present invention further provides a deodorization method for sewage treatment, which is applicable to the above-mentioned deodorization device and specifically comprises the following steps:

[0020] S1: When in use, first inject the sewage into the treatment tank through the water inlet, then open the valve on the L-shaped tube, so that the deodorant in the storage box can smoothly flow into the connecting tube through the L-shaped tube, then the deodorant is guided to the inside of the hollow tube, and finally evenly spread into the sewage in the treatment tank through the liquid outlet. This process ensures that the deodorant can directly penetrate into the sewage, so that it is easy to mix with the sewage quickly and fully. At the same time, the first connecting shaft drives the oil-absorbing cotton to move together when moving, effectively absorbing the oil stains on the surface of the sewage;

[0021] S2: The connecting pipe is driven to rotate clockwise through the transmission structure, the connecting pipe drives the first bevel gear to rotate clockwise, the first bevel gear drives several groups of first connecting plates to rotate, and several groups of first connecting plates drive the first spiral blades through the first connecting shaft to stir the sewage inside the treatment tank clockwise. At the same time, when the first bevel gear rotates clockwise, it transmits power through two groups of mutually meshing transmission bevel gears, so that the second bevel gear rotates counterclockwise. The rotation of the second bevel gear drives the rotation of multiple groups of second connecting plates. Several groups of second connecting plates drive the second spiral blades through the second connecting shaft to stir the sewage inside the treatment tank counterclockwise, thereby achieving all-round and efficient stirring of the sewage and improving the mixing of the deodorant and the sewage;

[0022] S3: When several groups of first connecting plates rotate clockwise, they will drive several groups of third gears to move respectively. Because several groups of third gears are meshed with the inner gear ring, while the third gears revolve clockwise around the axis of the hollow tube, the third gears themselves also rotate counterclockwise. This rotation drives the first spiral blades to rotate counterclockwise, thereby causing the sewage on the upper layer of the treatment tank to be introduced downward. At the same time, when several groups of second connecting plates rotate counterclockwise, they are meshed with the fixed gear through the connected fourth gear, so that while the fourth gears revolve counterclockwise around the axis of the hollow tube, the fourth gears also rotate counterclockwise. This rotation drives the second spiral blade to rotate counterclockwise, causing the sewage in the lower layer of the treatment tank to be directed upward, which not only realizes the upward and downward convection of sewage, but also the water flows they introduce collide with each other inside the treatment tank, forming a tumbling water surface. This tumbling and collision greatly enhances the mixing of sewage and deodorant. As the water surface rolls and fluctuates, the oil-absorbing cotton can contact and absorb the oil more widely. Not only is the oil effectively removed, but it also promotes the full mixing of the sewage surface and the deodorant, further improving the water quality. Finally, the sewage that has been fully mixed and treated is smoothly discharged from the outlet, completing the entire treatment process.

[0023] Beneficial effects of the present invention:

[0024] 1. When in use, the sewage enters the treatment tank from the water inlet, the L-shaped pipe valve is opened, and the deodorant enters the hollow pipe through the L-shaped pipe and the connecting pipe, and finally is evenly dispersed in the sewage through the liquid outlet hole to ensure that the deodorant penetrates directly and is easy to mix with the sewage quickly.

[0025] 2. The transmission structure drives the connecting pipe to rotate clockwise, driving the first bevel gear and the first spiral blade to stir the sewage clockwise. At the same time, the power is transmitted through the transmission bevel gear to make the second bevel gear rotate counterclockwise, driving the second spiral blade to stir the sewage counterclockwise, realizing all-round and efficient stirring. When the first connecting plate rotates clockwise, the third gear meshes with the inner gear ring to make the first spiral blade rotate counterclockwise to guide the upper sewage to flow downward. When the second connecting plate rotates counterclockwise, the fourth gear meshes with the fixed gear to make the second spiral blade rotate counterclockwise to push the lower sewage to rise, forming a rolling water surface, which greatly enhances the mixing effect of sewage and deodorant.

[0026] 3. The first connecting shaft drives the oil-absorbing cotton to move together when it moves, effectively absorbing the oil stains on the surface of the sewage. As the water surface rolls and fluctuates, the oil-absorbing cotton can contact and absorb these oil stains more widely, thereby greatly improving the oil removal efficiency. In this process, not only the oil stains are effectively removed, but also the sewage surface and the deodorant are fully mixed, further improving the water quality.

This process ensures that the deodorant can directly penetrate into the sewage, so that it is easy to mix with the sewage quickly and fully;

[0045] The stirring unit 300 includes a first bevel gear 306 fixedly mounted on the bottom end of the connecting tube 203, and the inner cavity of the first bevel gear 306 is rotatably connected to the outer surface of the hollow tube 204, a plurality of groups of first connecting plates 307 are mounted on the outer surface of the first bevel gear 306, the bottom ends of the plurality of groups of first connecting plates 307 are rotatably connected to the first connecting shafts 308, the outer surfaces of the bottom ends of the plurality of groups of first connecting shafts 308 are all mounted with first spiral blades 304, and the outer surface of the first connecting shafts 308 is fixedly mounted with a third gear 309, the bottom end of the first bevel gear 306 is symmetrically mounted with transmission bevel gears 310, and the two groups of transmission bevel gears 310 are both meshed with the first bevel gear 306, the outer surface of the hollow tube 204 is rotatably connected to the second bevel gear 311, and the third gear 309 is fixedly mounted on the outer surface of the first connecting shafts 308, The second bevel gears 311 are meshed with the two groups of transmission bevel gears 310, the outer surface of the second bevel gear 311 is installed with a plurality of second connecting plates 312, and the bottom ends of the plurality of second connecting plates 312 are rotatably connected with the second connecting shafts 313, the bottom ends of the plurality of second connecting shafts 313 are fixedly installed with fourth gears 315, and the outer surfaces of the plurality of second connecting shafts 313 are installed with second spiral blades 314, the outer surface of the bottom end of the hollow tube 204 is fixedly connected with a fixed gear 316, and the fixed gear 316 is meshed with a plurality of groups of inner gear rings 305, the inner wall of the treatment tank 101 is installed with an inner gear ring 305, and the inner gear ring 305 is meshed with a plurality of groups of third gears 309, the surface of the plurality of first connecting shafts 308 is installed with oil absorbing cotton 317, the treatment tank 1 01 is provided with a transmission structure at the top, through which the connecting pipe 203 is driven to rotate clockwise, the connecting pipe 203 drives the first bevel gear 306 to rotate clockwise, the first bevel gear 306 drives a plurality of groups of first connecting plates 307 to rotate, and the plurality of groups of first connecting plates 307 drive the first spiral blades 304 to stir the sewage inside the treatment tank 101 clockwise through the first connecting shaft 308. At the same time, when the first bevel gear 306 rotates clockwise, it transmits power through two groups of mutually meshing transmission bevel gears 310, so that the second bevel gear 311 rotates counterclockwise, and the rotation of the second bevel gear 311 drives the rotation of a plurality of groups of second connecting plates 312, and the plurality of groups of second connecting plates 312 drive the second spiral blades 304 to stir the sewage inside the treatment tank 101 clockwise through the second connecting shaft 313. The rotary blade 314 stirs the sewage inside the treatment tank 101 counterclockwise, achieving all-round and efficient stirring of the sewage and improving the mixing of the deodorant and the sewage. At the same time, the first connecting shaft 308 drives the oil-absorbing cotton 317 to move together during the movement, effectively absorbing the oil stains on the surface of the sewage. When several groups of first connecting plates 307 rotate clockwise, they will respectively drive several groups of third gears 309 to move. Because several groups of third gears 309 are meshed with the inner gear ring 305, while the third gear 309 revolves clockwise around the axis of the hollow tube 204, the third gear 309 itself also rotates counterclockwise. This rotation drives the first spiral blade 304 to rotate counterclockwise, thereby prompting the sewage on the upper layer of the treatment tank 101 to be introduced downward. At the same time,When the plurality of second connecting plates 312 rotate counterclockwise, they mesh with the connected fourth gear 315 and the fixed gear 316, so that the fourth gear 315 rotates counterclockwise while revolving counterclockwise around the axis of the hollow tube 204. This rotation drives the second spiral blade 314 to rotate counterclockwise, prompting the sewage in the lower layer of the treatment tank 101 to be introduced upward, which not only realizes the upward and downward convection of sewage, but also the water flows they introduce collide with each other inside the treatment tank 101, forming a rolling water surface. This rolling and collision greatly enhances the mixing effect of sewage and deodorant. With the rolling fluctuation of the water surface, the oil-absorbing cotton 317 can contact and absorb these oil stains more widely, not only the oil stains are effectively removed, but also the surface of the sewage is fully mixed with the deodorant, further improving the water quality.

[0046] The transmission structure includes a motor 301 installed on the top of the tank cover 102, the output end of the motor 301 is fixedly connected to the second gear 303, the outer surface of the connecting tube 203 is fixedly installed with a first gear 302, and the first gear 302 is meshed with the second gear 303. When the motor 301 is started, the motor 301 drives the second gear 303 to rotate counterclockwise, and the second gear 303 drives the first gear 302 to rotate clockwise, thereby causing the first gear 302 to drive the connecting tube 203 to rotate clockwise.

[0047] Bearings are symmetrically mounted on the outer surface of the hollow tube 204 , and one side of two sets of bearings are fixedly connected to the outer walls of two sets of transmission bevel gears 310 , respectively, to ensure the rotation stability of the transmission bevel gears 310 .

[0048] Several groups of second spiral blades 314 are located at the bottom of the treatment tank 101, and several groups of first spiral blades 304 are located above several groups of second spiral blades 314, so as to facilitate the downward introduction of sewage from above and the upward introduction of sewage from below.

[0049] Several groups of first spiral blades 304 are inclined to the left relative to the first connecting shaft 308, and several groups of second spiral blades 314 are inclined to the right relative to the second connecting shaft 313.

[0050] When the first bevel gear 306 drives the two sets of transmission bevel gears 310 to rotate, the two sets of transmission bevel gears 310 will drive the second bevel gear 311 to rotate in the opposite direction of the first bevel gear 306. The clockwise rotation of the first bevel gear 306 drives the two sets of transmission bevel gears 310 to rotate counterclockwise, and the two sets of transmission bevel gears 310 then drive the second bevel gear 311 to rotate counterclockwise.

[0051] Several groups of first spiral blades 304 are close to the inner wall of the treatment tank 101, and several groups of second spiral blades 314 are close to the middle of the inner cavity of the treatment tank 101. The connecting pipe 203 drives the first bevel gear 306 to rotate clockwise, and the first bevel gear 306 drives several groups of first connecting plates 307 to rotate. Several groups of first connecting plates 307 drive the first spiral blades 304 to stir the sewage inside the treatment tank 101 clockwise through the first connecting shaft 308.

The second bevel gear 311 drives several groups of second connecting plates 312 to rotate. Several groups of second connecting plates 312 drive the second spiral blades 314 to stir the sewage inside the treatment tank 101 counterclockwise through the second connecting shaft 313, thereby achieving all-round stirring and improving the mixing effect of the deodorant and sewage.

[0052] An observation window 104 is provided on one side of the treatment tank 101 . The observation window 104 is made of glass material, and the sewage treatment status can be observed through the observation window 104 .

[0053] Three sets of supporting legs are installed at the bottom end of the processing tank 101, and rubber pads are installed at the bottom ends of the supporting legs to support the processing tank 101 and ensure its stability.

[0054] Example 2

[0055] A deodorization method for sewage treatment, using the deodorization device for sewage treatment in Example 1, specifically comprises the following steps:

[0056] S1: When in use, firstly, the sewage is injected into the treatment tank 101 through the water inlet 105, and then the valve on the L-shaped tube 202 is opened, so that the deodorant in the storage box 201 can smoothly flow into the connecting tube 203 through the L-shaped tube 202, and then the deodorant is guided to the inside of the hollow tube 204, and finally evenly spread into the sewage in the treatment tank 101 through the liquid outlet 205. This process ensures that the deodorant can directly penetrate into the sewage, so that it is easy to mix with the sewage quickly and fully;

[0057] S2: The connecting pipe 203 is driven to rotate clockwise through the transmission structure, and the connecting pipe 203 drives the first bevel gear 306 to rotate clockwise. The first bevel gear 306 drives several groups of first connecting plates 307 to rotate. Several groups of first connecting plates 307 drive the first spiral blades 304 through the first connecting shaft 308 to stir the sewage inside the treatment tank 101 clockwise. At the same time, when the first bevel gear 306 rotates clockwise, it transmits power through two groups of mutually meshing transmission bevel gears 310, so that the second bevel gear 311 rotates counterclockwise. The rotation of the second bevel gear 311 drives the rotation of multiple groups of second connecting plates 312. Several groups of second connecting plates 312 drive the second spiral blades 314 through the second connecting shaft 313 to stir the sewage inside the treatment tank 101 counterclockwise, thereby achieving all-round and efficient stirring of the sewage and improving the mixing of the deodorant and the sewage. At the same time, the first connecting shaft 308 drives the oil-absorbing cotton 317 to move together during the movement, effectively absorbing the oil stains on the surface of the sewage;

[0058] S3: When several groups of first connecting plates 307 rotate clockwise, they will drive several groups of third gears 309 to move respectively. Because several groups of third gears 309 are meshed with the inner gear ring 305, while the third gear 309 revolves clockwise around the axis of the hollow tube 204, the third gear 309 itself also rotates counterclockwise. This rotation drives the first spiral blade 304 to rotate counterclockwise, thereby prompting the sewage on the upper layer of the treatment tank 101 to be introduced downward. At the same time, when several groups of second connecting plates 312 rotate counterclockwise, they are meshed with the fixed gear 316 through the connected fourth gear 315, so that while the fourth gear 315 revolves counterclockwise around the axis of the hollow tube 204, the third gear 309 itself also rotates counterclockwise. This rotation drives the first spiral blade 304 to rotate counterclockwise, thereby prompting the sewage on the upper layer of the treatment tank 101 to be introduced downward. At the same time, when several groups of second connecting plates 312 rotate counterclockwise, they are meshed with the fixed gear 316 through the connected fourth gear 315, so that while the fourth gear 315 revolves counterclockwise around the axis of the hollow tube 204, the third gear 309 rotates counterclockwise. The fourth gear 315 also rotates counterclockwise, and this rotation drives the second spiral blade 314 to rotate counterclockwise, prompting the sewage in the lower layer of the treatment tank 101 to be introduced upward, which not only realizes the upward and downward convection of sewage, but also the water flows they introduce collide with each other inside the treatment tank 101, forming a tumbling water surface. This tumbling and collision greatly enhances the mixing of sewage and deodorant. With the rolling and fluctuation of the water surface, the oil-absorbing cotton 317 can contact and absorb these oil stains more widely. Not only the oil stains are effectively removed, but also the surface layer of sewage and the deodorant are fully mixed, further improving the water quality. Finally, the sewage after being fully mixed and treated is smoothly discharged from the outlet 103, completing the entire treatment process.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

10. A deodorization method for sewage treatment, using the deodorization device according to claim 1, specifically comprising the following steps: S1: When in use, the sewage is first injected into the treatment tank (101) through the water inlet (105), and then the valve on the L-shaped tube (202) is opened, so that the deodorant in the storage box (201) can smoothly flow into the connecting tube (203) through the L-shaped tube (202), and then the deodorant is guided to the inside of the hollow tube (204), and finally evenly spread into the sewage in the treatment tank (101) through the liquid outlet (205). This process ensures that the deodorant can directly penetrate into the sewage, so that it is easy to mix with the sewage quickly and fully; S2: The connecting pipe (203) is driven to rotate clockwise through the transmission structure, the connecting pipe (203) drives the first bevel gear (306) to rotate clockwise, the first bevel gear (306) drives a plurality of groups of first connecting plates (307) to rotate, and the plurality of groups of first connecting plates (307) drive the first spiral blades (304) to stir the sewage in the treatment tank (101) clockwise through the first connecting shaft (308). At the same time, when the first bevel gear (306) rotates clockwise, it transmits power through two groups of mutually meshing transmission bevel gears (310), so that The second bevel gear (311) rotates counterclockwise, and the rotation of the second bevel gear (311) drives the rotation of multiple sets of second connecting plates (312). The multiple sets of second connecting plates (312) drive the second spiral blades (314) to stir the sewage inside the treatment tank (101) counterclockwise via the second connecting shaft (313), thereby achieving all-round and efficient stirring of the sewage and improving the mixing of the deodorant and the sewage. At the same time, the first connecting shaft (308) drives the oil-absorbing cotton (317) to move together during the movement, thereby effectively absorbing the oil stains on the surface of the sewage. S3: When the plurality of first connecting plates (307) rotate clockwise, they will respectively drive the plurality of third gears (309) to move. Because the plurality of third gears (309) are meshed with the inner gear ring (305), while the third gear (309) revolves clockwise around the axis of the hollow tube (204), the third gear (309) itself also rotates counterclockwise. This rotation drives the first spiral blade (304) to rotate counterclockwise, thereby causing the sewage on the upper layer of the treatment tank (101) to be introduced downward. At the same time, when the plurality of second connecting plates (312) rotate counterclockwise, they mesh with the connected fourth gear (315) and the fixed gear (316), so that the fourth gear (315) rotates counterclockwise around the axis of the hollow tube (204). While the needle is revolving, the fourth gear (315) also rotates counterclockwise. This rotation drives the second spiral blade (314) to rotate counterclockwise, prompting the sewage in the lower layer of the treatment tank (101) to be introduced upward, not only realizing the upward and downward convection of sewage, but also the water flows introduced by them collide with each other inside the treatment tank (101), forming a rolling water surface. This rolling and collision greatly enhances the mixing of sewage and deodorant. With the rolling and fluctuation of the water surface, the oil-absorbing cotton (317) can contact and absorb these oil stains more widely. Not only is the oil stain effectively removed, but it also promotes the full mixing of the sewage surface and the deodorant, further improving the water quality. Finally, the sewage after being fully mixed and treated is smoothly discharged from the outlet (103), completing the entire treatment process.
