[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a sewage deodorization and purification device and a purification method based on environmental protection, having the following beneficial effects: 1. The sewage deodorization and purification equipment based on environmental protection introduces sewage into the biological reaction tank, enabling the sewage to undergo biological deodorization treatment inside the biological reaction tank. After the sewage enters the biological reaction tank, the pumping component is started. The pumping component pumps out the sewage in the biological reaction tank and conveys it towards the turbine spraying mechanism through the connecting valve core. After the sewage passes through the connecting valve core, it enters the turbine chamber through the side connecting pipe and is pumped, and then sprays upward through the spraying pipe on the cross-section of the turbine chamber, enabling the sewage to disperse above the biological reaction tank and then fall back into the biological reaction tank, so that the sewage is mixed with aerobic microorganisms in the biological reaction tank and then sprayed into the air, increasing the oxygen of the aerobic microorganisms in the sewage, thereby promoting the degradation of organic matter by aerobic microorganisms and reducing the generation of odors. Then, after the pumping component and the turbine spraying mechanism work for a period of time, they move towards the switching mechanism through the linkage mechanism, causing the switching mechanism to adjust the connecting valve core, so that the connecting valve core changes from connecting the pumping component and the side connecting pipe to connecting the pumping component and the spiral filtering component. The pumping component starts to pump sewage to the spiral filtering component, enabling the sewage after biological deodorization treatment to be filtered through the spiral filtering component. After the aerobic microorganisms and impurities in the sewage in the biological reaction tank pass through the spiral filtering component, the aerobic microorganisms in the sewage are filtered and recovered for reuse.

[0016] 2. In the sewage deodorization and purification equipment based on environmental protection, after the sewage pumped into the turbine chamber by the side connecting pipe impacts the rotating turbine in the turbine spraying mechanism, the sewage causes the rotating turbine to rotate inside the turbine chamber. When the rotating turbine rotates, it turbocharges the sewage, causing the sewage to spray out from the spraying pipe on the end face of the turbine chamber. At the same time, when the rotating turbine rotates, it drives the gathering plate at its bottom to rotate at the bottom of the turbine chamber. Thus, the rotating gathering plate stirs the sewage inside the biological reaction tank, enabling the sewage that has been aerated by spraying into the air to quickly mix with the sewage after falling back into the biological reaction tank, thereby deodorizing the sewage in the biological reaction tank faster. A baffle is arranged above the spraying pipe. The baffle is installed above the middle of the biological reaction tank through a connecting rod. After the sewage sprays upward through the spraying pipe, the sewage impacts on the baffle and disperses, thereby achieving a better sewage dispersion effect.

[0017] 3. The sewage deodorization and purification equipment based on environmental protection uses the mounting plate in the linkage mechanism to position and support the expanding guide wheel, so that the expanding guide wheel expands the transmission belt at the driving wheel, separating the transmission belt from the driving wheel. Then, when it is necessary to connect the pumping motor to the spiral filtering component, the moving carrier plate drives the moving clamping wheel above it to move towards the driving wheel, so that the moving clamping wheel can squeeze the transmission belt above the expanding guide wheel towards the middle, making the transmission belt tighten, and then making the transmission belt contact the driving wheel, so that the pumping motor provides power for the spiral filtering component. While the pumping component pumps sewage to the spiral filtering component, the spiral filtering component can be started synchronously to filter the pumped sewage. One end of the transmission belt is sleeved on the driven wheel. The transmission belt passes between the two moving clamping wheels, bypasses the outside of the two expanding guide wheels, and is suspended at the bottom of the driving wheel. When the moving clamping wheel moves downward, the moving clamping wheel squeezes the transmission belt at the expanding guide wheel towards the middle, and then the transmission belt at the bottom of the driving wheel approaches the driving wheel until the transmission belt tightens, realizing the pumping of sewage to the spiral filtering component and starting the spiral pumping component to filter the sewage at the same time.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-8 , an environmentally friendly sewage deodorization and purification device, including a biological reaction tank 1, a spiral filtration assembly 2 is arranged on one side of the biological reaction tank 1, a turbine spraying mechanism 3 is arranged inside the biological reaction tank 1, and a pumping assembly 4 is arranged between the spiral filtration assembly 2 and the biological reaction tank 1; the turbine spraying mechanism 3 includes a turbine chamber 31, a side connecting pipe 32 and a spraying pipe 33; the side connecting pipe 32 is located on the side of the turbine chamber 31, the spraying pipe 33 is located at the end face of the turbine chamber 31, one end of the pumping assembly 4 is provided with a switching mechanism 5 and a connecting valve core 41, the other end of the side connecting pipe 32 is connected to the pumping assembly 4 through the connecting valve core 41, the switching mechanism 5 is located on one side of the connecting valve core 41, the connecting valve core 41 is located at one end of the pumping assembly 4, the pumping assembly 4 includes a pumping driving mechanism 6 and a linkage mechanism 7, and the pumping driving mechanism 6 is connected to the spiral filtration assembly 2 through the linkage mechanism 7; the linkage mechanism 7 is located on one side of the switching mechanism 5; the linkage mechanism 7 moves in the direction of the switching mechanism 5, driving the switching mechanism 5 to adjust the connecting valve core 41 to only connect the pumping assembly 4 and the spiral filtration assembly 2, and the linkage mechanism 7 connects the power cooperation between the pumping driving mechanism 6 and the spiral filtration assembly 2.

[0022] During use, sewage is introduced into the interior of the biological reaction tank 1, and the sewage undergoes biological deodorization treatment inside the biological reaction tank 1. After the sewage enters the interior of the biological reaction tank 1, the pumping assembly 4 is started. The pumping assembly 4 pumps out the sewage in the biological reaction tank 1 and conveys it towards the turbine spraying mechanism 3 through the connecting valve core 41. After the sewage passes through the connecting valve core 41, it enters the turbine chamber 31 through the side connecting pipe 32 for pumping, and then sprays upward through the spraying pipe 33 on the cross-section of the turbine chamber 31, enabling the sewage to disperse above the biological reaction tank 1 and then fall back into the biological reaction tank 1. This allows the sewage to mix with aerobic microorganisms in the biological reaction tank 1 and then be sprayed into the air, increasing the oxygen of the aerobic microorganisms in the sewage, thereby promoting the degradation of organic matter by aerobic microorganisms and reducing the generation of odors. Then, after the pumping assembly 4 and the turbine spraying mechanism 3 work for a period of time, they move towards the switching mechanism 5 through the linkage mechanism 7, causing the switching mechanism 5 to adjust the connecting valve core 41, so that the connecting valve core 41 changes from connecting the pumping assembly 4 and the side connecting pipe 32 to connecting the pumping assembly 4 and the spiral filtering assembly 2. The pumping assembly 4 starts to pump sewage towards the spiral filtering assembly 2, enabling the sewage after biological deodorization treatment to be filtered through the spiral filtering assembly 2. After the aerobic microorganisms and impurities in the sewage inside the biological reaction tank 1 pass through the spiral filtering assembly 2, the aerobic microorganisms in the sewage are filtered and recovered for reuse.

[0023] Furthermore, the turbine spraying mechanism 3 further includes a converging plate 34 and a rotating turbine 35. The rotating turbine 35 is located inside the turbine chamber 31. The side edge of the rotating turbine 35 faces the side connecting pipe 32, and the rotation center of the rotating turbine 35 faces the spraying pipe 33. The spraying pipe 33 is vertically arranged in the middle of the biological reaction tank 1. The converging plate 34 is located at the outer bottom of the turbine chamber 31, and the converging plate 34 is coaxially connected to the rotating turbine 35. After the sewage pumped in by the side connecting pipe 32 enters the turbine chamber 31 through the rotating turbine 35 in the turbine spraying mechanism 3, the sewage impacts the rotating turbine 35, causing the rotating turbine 35 to rotate inside the turbine chamber 31. When the rotating turbine 35 rotates, it turbocharges the sewage, causing the sewage to spray out from the spraying pipe 33 at the end face of the turbine chamber 31. At the same time, when the rotating turbine 35 rotates, it drives the converging plate 34 at its bottom to rotate at the bottom of the turbine chamber 31. Thus, the rotating converging plate 34 stirs the sewage inside the biological reaction tank 1, enabling the sewage that has been aerated by spraying into the air to quickly mix with the sewage after falling back into the biological reaction tank 1, thereby deodorizing the sewage in the biological reaction tank 1 faster. A baffle is arranged above the spraying pipe 33, and the baffle is installed above the middle of the biological reaction tank 1 through a connecting rod. After the sewage sprays upward through the spraying pipe 33, the sewage impacts on the baffle for dispersion, thereby achieving a better sewage dispersion effect. A connecting rod is arranged above the turbine chamber 31 to fix the turbine chamber 31 at the bottom of the inner cavity of the biological reaction tank 1.

[0024] Further, the pumping assembly 4 further includes a centrifugal pump 42. The impeller of the centrifugal pump 42 is connected to the pumping drive mechanism 6. A pumping pipe 43 is provided at the water outlet of the centrifugal pump 42. The other end of the pumping pipe 43 is horizontally placed on one side of the side connecting pipe 32. A three-way pipe 44 is provided at the connection between the pumping pipe 43 and the side connecting pipe 32. The bottom of the three-way pipe 44 is connected to the side connecting pipe 32. The side of the three-way pipe 44 is connected to the pumping pipe 43. The upper part of the three-way pipe 44 is connected to the spiral filtering assembly 2. The connection valve core 41 is located inside the three-way pipe 44. The switching mechanism 5 is located outside the three-way pipe 44. Driven by the pumping drive mechanism 6, the impeller of the centrifugal pump 42 in the pumping assembly 4 rotates, thereby pumping the sewage in the biological reaction tank 1 into the three-way pipe 44 through the pumping pipe 43 by the centrifugal pump 42. Then, the switching mechanism 5 switches the connection direction of the three-way pipe 44 to pump the sewage to the side connecting pipe 32 or the spiral filtering assembly 2.

[0025] Further, the switching mechanism 5 includes a switching gear 51, a switching shaft 52, and a reversing gear 53. One end of the switching shaft 52 penetrates through the three-way pipe 44 and extends into the three-way pipe 44. The connection valve core 41 is provided with two mutually perpendicular through holes 411. One of the through holes 411 is arranged facing the pumping pipe 43. The switching shaft 52 is fixedly connected to the connection valve core 41. The switching gear 51 is installed at the other end of the switching shaft 52. The reversing gear 53 is installed outside the switching gear 51, and the reversing gear 53 is meshed with the switching gear 51. The reversing gear 53 is connected to the linkage mechanism 7. The connection valve core 41 in the three-way pipe 44 is driven by the switching mechanism 5, so that the two mutually perpendicular through holes 411 on the connection valve core 41 rotate around the through hole 411 facing the pumping pipe 43 as the axis, and the other through hole 411 switches between the side connecting pipe 32 and the pumping pipe 43, thereby realizing the switching between the sewage leading to the turbine spraying mechanism 3 and the spiral filtering assembly 2. When the linkage mechanism 7 moves towards the switching mechanism 5, the switching gear 51 in the switching mechanism 5 is driven to rotate by the reversing gear 53. The switching gear 51 drives the connection valve core 41 to rotate through the switching shaft 52, so that the other through hole 411 on the connection valve core 41 is switched from being connected to the side connecting pipe 32 to being connected to the spiral filtering assembly 2. The reversing gear 53 is fixedly arranged at one side of the switching gear 51.

[0026] Further, the pumping drive mechanism 6 includes a pumping motor 61, a coupling 62, and a drive shaft 63. The pumping motor 61 is located outside the pumping assembly 4. The output end of the pumping motor 61 is connected to the coupling 62. One end of the drive shaft 63 is connected to the pumping assembly 4, and the other end of the drive shaft 63 is connected to the coupling 62. A drive wheel 64 is further provided on the drive shaft 63, and the drive wheel 64 is connected to the linkage mechanism 7. The pumping motor 61 in the pumping drive mechanism 6 drives the drive shaft 63 to rotate through the coupling 62, and the drive shaft 63 drives the impeller of the centrifugal pump 42 in the pumping assembly 4 to rotate, thereby pumping out the sewage in the biological reaction tank 1. At the same time, after being connected to the drive wheel 64 through the linkage mechanism 7, when the pumping motor 61 rotates, it can also drive the spiral filtration assembly 2 to operate.

[0027] Further, the linkage mechanism 7 includes a mounting plate 71, an expanding guide wheel 72, a moving clamping wheel 73, and a moving carrier plate 74. The mounting plate 71 is located on one side of the pumping motor 61. The expanding guide wheel 72 is rotatably provided on the surface of the mounting plate 71. The moving carrier plate 74 is slidably provided above the mounting plate 71, and the moving carrier plate 74 slides up and down relative to the mounting plate 71. The moving clamping wheel 73 is rotatably provided on the surface of the moving carrier plate 74, and the moving clamping wheel 73 is located inside the expanding guide wheel 72. The mounting plate 71 in the linkage mechanism 7 positions and supports the expanding guide wheel 72, so that the expanding guide wheel 72 expands the transmission belt at the drive wheel 64, separating the transmission belt from the drive wheel 64. Then, when it is necessary to connect the pumping motor 61 to the spiral filtration assembly 2, the moving carrier plate 74 drives the moving clamping wheel 73 above it to move towards the drive wheel 64, so that the moving clamping wheel 73 can squeeze the transmission belt above the expanding guide wheel 72 towards the middle, so that the transmission belt can be tightened, and then the transmission belt contacts the drive wheel 64, so that the pumping motor 61 provides power for the spiral filtration assembly 2. While the pumping assembly 4 pumps sewage to the spiral filtration assembly 2, the spiral filtration assembly 2 can be started synchronously to filter the pumped sewage. One end of the transmission belt is sleeved on the driven wheel 27, the transmission belt passes between the two moving clamping wheels 73, and after bypassing the outside of the two expanding guide wheels 72, it is suspended at the bottom of the drive wheel 64. When the moving clamping wheel 73 moves downward, the moving clamping wheel 73 squeezes the transmission belt at the expanding guide wheel 72 towards the middle, and then the transmission belt at the bottom of the drive wheel 64 approaches the drive wheel 64 until the transmission belt is tightened.

[0028] Further, the linkage mechanism 7 further includes a telescopic rod 75 and a switching rack 76. The telescopic rod 75 is located above the mounting plate 71, and the switching rack 76 is located outside the moving carrier plate 74. The output end of the telescopic rod 75 is connected to the moving carrier plate 74, and the switching rack 76 is connected to the switching mechanism 5. The telescopic rod 75 in the linkage mechanism 7 drives the moving carrier plate 74 to move along the mounting plate 71, so that the moving carrier plate 74 drives the moving clamping wheel 73 to move relative to the expansion guide wheel 72. At the same time, the telescopic rod 75 drives the switching rack 76 to move towards the switching gear 51 in the switching mechanism 5, and the switching rack 76 is used to drive the switching gear 51 to rotate, thereby realizing the switching process of the through hole 411 on the communication valve core 41.

[0029] Further, the spiral filtration assembly 2 includes a support frame 21, a conveying cylinder 22, a spiral rod 23 and a filtration partition 24. The support frame 21 is located on one side outside the biological reaction tank 1. The conveying cylinder 22 is horizontally arranged above the support frame 21. One end of the conveying cylinder 22 is provided with a connecting pipe 25 connected to the pumping assembly 4. The spiral rod 23 is rotatably arranged inside the conveying cylinder 22. The filtration partitions 24 are evenly distributed on the spiral rod 23 and are horizontally arranged inside the conveying cylinder 22. The support frame 21 in the spiral filtration assembly 2 fixes the conveying cylinder 22 on one side outside the biological reaction tank 1. When the spiral rod 23 in the middle of the conveying cylinder 22 rotates, the sewage pumped by the pumping assembly 4 is conveyed to the tail of the conveying cylinder 22. When being conveyed, the sewage passes through the filtration partition 24 to filter aerobic microorganisms and impurities in the sewage.

[0030] Further, a sewage storage tank 26 is arranged at the bottom of the conveying cylinder 22. The sewage storage tank 26 is located between the two filtration partitions 24. One end of the spiral rod 23 extends outside the conveying cylinder 22, and a driven wheel 27 is arranged on the spiral rod 23. The driven wheel 27 is connected to the linkage mechanism 7. The sewage storage tank 26 arranged at the bottom of the conveying cylinder 22 intercepts aerobic microorganisms and impurities filtered between the two filtration partitions 24, and the filtered sewage continues to be conveyed forward.
