In the present invention, the synergistic effect of the first stirring blade and the baffle can significantly increase the turbulence intensity and shear force of the fluid in the stirring area. The design of the baffle can guide the fluid to flow along a special path, so that the effect of the first stirring blade is more concentrated and efficient, thereby greatly shortening the mixing time and improving the mixing uniformity. The wavy design of the first stirring blade allows the blade to have a larger bending angle and thickness, which can generate a stronger stirring force.

The increase of dissolved oxygen can accelerate the biochemical reaction rate in the sewage; 4. In the present invention, the mixing motor rotates to stir the sewage and drives the scraper to rotate, thereby driving the convex column to rotate. Since the top of the convex column is set in a semicircular shape, and the top of the convex column is fixed to the spring, the convex column is constantly popped out in the middle of the filter hole while the scraper rotates, and the suspended matter in the filter hole is pushed upward to prevent the suspended matter from clogging the filter and affecting the filtering effect. 5. In the present invention, a cleaning plate used in conjunction with the flocculation tank is fixedly mounted on one end of the second stirring blade. When the second stirring blade stirs the sewage, the cleaning plate is driven to rotate to scrape off the residue on the inner wall of the flocculation tank, facilitating subsequent cleaning work.

[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] refer to Figure 1 A sewage purification device for environmental protection includes a purification tank 1 and a flocculation tank 35. The bottom of the purification tank 1 is fixedly installed with a support leg 2, and the top of the purification tank 1 is equipped with a first top cover 3, and the top of the first top cover 3 is connected to a sewage inlet pipe 4.

[0020] refer to Figure 2 and Figure 3 A mounting plate 10 is fixedly installed in the inner cavity of the purification tank 1, a water-permeable hole 11 is opened inside the mounting plate 10, and a filter bin 5 is formed between the upper surface of the mounting plate 10 and the inner cavity of the purification tank 1, an annular fixing block 6 is fixedly installed on the inner wall of the filter bin 5, a sliding ring 7 is rotatably installed inside the fixing block 6, a first filter frame 8 is fixedly installed on the inner wall of the sliding ring 7, a dual-axis motor 12 is fixed to the bottom of the mounting plate 10, an upper output end of the dual-axis motor 12 passes through the mounting plate 10 and rotates with the mounting plate 10, and the upper output end of the dual-axis motor 12 is fixed to the lower surface of the first filter frame 8.

[0021] Furthermore, when in use, the water inlet pipe 4 passes the sewage into the first filter frame 8 to filter the debris in the sewage, and the dual-axis motor 12 rotates, thereby driving the first filter frame 8 to rotate, and then driving the filtered debris to rotate, and the sewage on the surface of the debris is centrifugally separated to improve the filtering effect. After the work is completed, the first top cover 3 can be disassembled, and the debris in the first filter frame 8 can be taken out for centralized treatment.

[0022] refer to Figure 2 and Figure 3 The lower surface of the mounting plate 10 and the inner cavity of the purification tank 1 form a purification chamber 9, a stirring rod 19 is fixedly mounted on the lower output end of the dual-axis motor 12, a wavy first stirring blade 20 is fixedly mounted on the surface of the stirring rod 19, and a baffle 21 used in conjunction with the first stirring blade 20 is fixedly mounted on the inner wall of the purification chamber 9.

[0023] Furthermore, when in use, the synergistic effect of the first stirring blade 20 and the baffle 21 can significantly increase the turbulence intensity and shear force of the fluid in the stirring area. The design of the baffle 21 can guide the fluid to flow along a special path, making the effect of the first stirring blade 20 more concentrated and efficient, thereby greatly shortening the mixing time and improving the mixing uniformity. The wavy design of the first stirring blade 20 makes the blade have a larger bending angle and thickness. This design can generate a stronger stirring force. Compared with the blades with a flat design, the wavy blade can mix the liquid faster and more evenly. The special shape of the wavy blade increases the contact area between the blade and the liquid, so that more liquid can be effectively stirred and mixed, thereby improving the overall mixing efficiency.

[0024] refer to Figure 1 and Figure 2 An aerator 22 is fixedly installed at the bottom of the purification tank 1, the stirring rod 19 is hollow, and a plurality of aeration holes 23 are provided on the surface of the stirring rod 19. The air outlet end of the aerator 22 passes through the purification tank 1 and is connected to the bottom of the stirring rod 19, and the air outlet end of the aerator 22 is rotatably matched with the stirring rod 19.

[0025] Furthermore, when in use, aeration is performed while the sewage is stirred. Aeration and oxygenation increase the dissolved oxygen content in the sewage by introducing air into the sewage, thereby providing the necessary oxygen environment for microorganisms, promoting the growth and reproduction of microorganisms, and stirring the sewage so that floating objects, dissolved objects, microorganisms, etc. in the sewage are evenly distributed, thereby increasing the contact opportunities between organic matter and microorganisms, accelerating the rate of biochemical reactions, and improving the efficiency of sewage treatment.

[0026] refer to Figure 2 and Figure 4 A reciprocating thread 13 is provided on the top of the stirring rod 19, and limit blocks 14 are fixedly installed at both ends of the reciprocating thread 13, and a bubble baffle 16 is threadedly installed on the surface of the reciprocating thread 13 to block the foam generated when the sewage is stirred. A slide groove 15 is fixedly installed inside the purification bin 9, and the bubble baffle 16 slides inside the slide groove 15. A drainage hole 17 is opened inside the bubble baffle 16 for the sewage to fall into the purification bin 9, and a plurality of spikes 18 are fixedly installed on the lower surface of the bubble baffle 16, and the bubble baffle 16 is arranged between the limit blocks 14. When the bubble baffle 16 touches the limit blocks 14 during movement, it moves in the opposite direction, so that the bubble baffle 16 moves up and down to drive the spikes 18 to puncture the foam. Piercing the foam during the stirring process can increase the contact area between the gas and the liquid in the sewage, which is conducive to the dissolution of oxygen in the liquid, and the concentration of dissolved oxygen is increased, providing more favorable conditions for the growth of microorganisms and the degradation of pollutants. The increase of dissolved oxygen can accelerate the biochemical reaction rate in the sewage, especially the aerobic reaction process, thereby accelerating the removal rate of pollutants and improving the overall efficiency of sewage treatment.

[0027] refer to Figure 2 and Figure 3 A disinfection barrel 24 is fixedly installed on both sides of the purification tank 1, and a first liquid replenishing tube 25 is connected to one side of the disinfection barrel 24. Two symmetrical liquid storage tubes 27 are fixedly installed on the lower surface of the mounting plate 10. The top of the disinfection barrel 24 is connected to a liquid inlet tube 26 that runs through the purification tank 1. The liquid inlet tube 26 is connected to the liquid storage tube 27. A top tube 28 that runs through the inside of the liquid storage tube 27 is provided on the upper surface of the bubble baffle plate 16, and the top tube 28 is slidably matched with the liquid storage tube 27, and a plurality of liquid inlet holes 29 are opened on the top of the top tube 28.

[0028] Furthermore, when in use, when the bubble baffle 16 moves upward, it drives the top pipe 28 to move upward, so that the part with the liquid inlet hole 29 is inserted into the liquid storage tube 27, so that the disinfectant flows along the liquid inlet hole 29 and then into the top pipe 28, and then flows into the purification chamber 9 to disinfect the sewage, so that the disinfectant can be added intermittently to avoid the energy waste that may be caused by continuous addition.

[0029] refer to Figure 2 A deodorizing barrel 30 is fixedly installed on both sides of the purification tank 1 and below the disinfection barrel 24 , one side of the deodorizing barrel 30 is connected to a second liquid replenishing pipe 31 , and the top of the deodorizing barrel 30 is connected to a nozzle 32 that runs through the inside of the purification chamber 9 .

[0030] Furthermore, when in use, during the process of sewage treatment and stirring, the deodorant is sprayed into the purification chamber 9 through the nozzle 32. The chemical components or microorganisms in the deodorant can react with the malodorous gases (such as hydrogen sulfide, ammonia, etc.) in the sewage, and the malodorous gases are converted into harmless or low-harmful substances through chemical reactions, adsorption or biodegradation, thereby significantly reducing the malodor in the sewage and improving the environmental air quality. The reduction of malodor can provide a more comfortable working environment and reduce the adverse health effects caused by long-term exposure to malodorous gases.

[0031] refer to Figure 1 A delivery pipe 33 is connected to one side of the purification tank 1. The delivery pipe 33 is located at the upper part of the purification bin 9. After the sewage is aerated, the suspended matter in the sewage is precipitated at the bottom of the purification bin 9. The purification tank 1 is connected to the flocculation tank 35 through the delivery pipe 33. The delivery pipe 33 is externally connected with a delivery pump to deliver the preliminarily treated sewage to the flocculation tank 35. A sewage pipe 34 connected to the purification bin 9 is fixedly installed at the bottom of the purification tank 1. The sewage pipe 34 is externally connected with a sewage pump to discharge the precipitated suspended matter through the sewage pipe 34.

[0032] refer to Figure 1 and Figure 6 A second top cover 36 is mounted on the top of the flocculation tank 35, and a cushion block 40 is fixedly installed in the inner cavity of the flocculation tank 35. A second filter frame 41 is mounted on the upper surface of the cushion block 40, and a filter hole 42 is opened at the bottom of the second filter frame 41.

[0033] Furthermore, when in use, the initially treated sewage is transported to the second filter frame 41, filtered again through the filter holes 42 and then falls downward, further improving the purification effect, and the filtered impurities remain in the second filter frame 41 and can be taken out by opening the second top cover 36.

[0034] refer to Figure 1 and Figure 5 A mixing motor 37 is fixedly installed on the top of the second top cover 36, and the output end of the mixing motor 37 passes through the second filter frame 41 and rotates with the second filter frame 41. The output end of the mixing motor 37 is equipped with a detachable transmission shaft 43, and a second stirring blade 48 is fixedly installed on the lower part of the transmission shaft 43. A flocculation barrel 38 is fixedly installed on one side of the flocculation tank 35, one end of the flocculation barrel 38 is connected to the third liquid replenishment pipe 39, and the top of the flocculation barrel 38 is connected to the flocculation tank 35 for delivering flocculant into the flocculation tank 35.

[0035] Furthermore, when using, the flocculant is added to the sewage and stirred at the same time. Stirring can make the flocculant fully and evenly dispersed in the sewage and fully contact with the suspended matter, colloidal substances, etc. in the sewage. This uniform mixing ensures that the flocculant can fully exert its adsorption, bridging and netting functions, thereby improving the flocculation effect. During the stirring process, the flocculant interacts with the particles in the sewage, and through the mechanisms of electrostatic adsorption, electrical neutralization, bridging, etc., the particles are aggregated to form larger flocs. These flocs are easy to settle or filter, thereby improving the treatment efficiency of sewage.

[0036] refer to Figure 5-Figure 8 A scraper 44 is fixedly installed on the top of the transmission shaft 43 and below the second filter frame 41. A plurality of through holes 45 are opened on the upper surface of the scraper 44. A convex column 46 corresponding to the filter hole 42 is slidably installed inside the through hole 45. The top of the convex column 46 is semicircular, and a spring 47 is fixedly installed between the lower surface of the convex column 46 and the scraper 44.

[0037] Furthermore, when in use, the mixing motor 37 rotates to stir the sewage and drives the scraper 44 to rotate, thereby driving the boss 46 to rotate. Since the top of the boss 46 is set to be semicircular, and the top of the boss 46 is fixed to the spring 47, when the scraper 44 rotates, the boss 46 continuously pops out in the middle of the filter hole 42, pushing the suspended matter in the filter hole 42 upward, preventing the suspended matter from clogging the filter hole 42 and affecting the filtering effect.

[0038] refer to Figure 5-Figure 8One side of the flocculation tank 35 is connected to a drain pipe 50 for discharging the water purified by flocculation precipitation, and the bottom of the flocculation tank 35 is connected to the sewage pipe 34. One end of the second stirring blade 48 is fixedly mounted with a cleaning plate 49 used in conjunction with the flocculation tank 35. When the second stirring blade 48 stirs the sewage, the cleaning plate 49 is driven to rotate to scrape off the residue on the inner wall of the flocculation tank 35, so as to facilitate the subsequent cleaning work.
