Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a high-efficiency filtration treatment device for industrial wastewater. Background Technology

[0002] With the rapid development of industry, the composition of wastewater is becoming increasingly complex. Traditional filtration technologies are unable to efficiently treat high-viscosity, high-COD, and oily wastewater, and are prone to problems such as filter media clogging and high energy consumption. As a result, high-efficiency filtration treatment devices based on heating technology have emerged. These devices significantly improve filtration efficiency and adaptability through heat-driven pretreatment. Heating technology can destroy colloidal stability, promote pollutant flocculation, and improve wastewater treatment efficiency. In existing technologies, heating wastewater with electric heating tubes is a low-cost and high-efficiency treatment method. However, electric heating tubes are usually installed inside the wastewater treatment device, making it difficult to inspect and replace them, which poses certain risks in long-term use.

[0003] Patent CN216662745U discloses a high-efficiency industrial wastewater filtration device. This patent includes a first support frame, a lid, a water tank, and a heating wire. The water tank is mounted on the upper part of the first support frame, and a stirring box is mounted on the rear side of the first support frame. The heating wire is mounted on the water tank, and the lid is snapped onto one side of the water tank. The industrial wastewater is heated to a high temperature by the heating wire, improving the filtration quality. A motor can be started, which drives the stirring rod to rotate, thus stirring the heated industrial wastewater and achieving high-efficiency filtration. This improves the efficiency of wastewater filtration to a certain extent. While this patent solves the aforementioned problems, it still presents the issue of the heating device being in direct contact with the wastewater, making inspection and replacement difficult and posing a certain degree of danger. Therefore, this patent proposes a high-efficiency industrial wastewater filtration device to address these problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-efficiency filtration treatment device for industrial wastewater, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a high-efficiency filtration treatment device for industrial wastewater, comprising a lower filter tank, an upper filter tank connected to the upper surface of the lower filter tank via a flange, a limiting cylinder fixedly connected to the upper surface of the upper filter tank, a mounting base sleeved on the inner surface of the limiting cylinder, a U-shaped electric heating tube fixedly connected to the lower surface of the mounting base, a stain discharge device for convenient discharge of inorganic pollutants provided on the left side of the lower filter tank, a flocculant addition device for uniformly adding flocculant provided on the top of the upper filter tank, a main shaft rotatably connected to the inner surface of the bottom end of the lower filter tank, an agitator fixedly connected to the circumferential surface of the main shaft, and a filter screen fixedly connected to the circumferential surface of the main shaft. A movable locking block is fixedly connected to the top lower surface of the mounting base. A fixed locking block is fixedly connected to the circumferential surface of the limiting cylinder. A sleeve is fixedly connected to the left side of the fixed locking block. A positioning rod is slidably connected to the inner surface of the left end of the sleeve. A sliding ring is fixedly connected to the circumferential surface of the positioning rod. An L-shaped through groove is opened on the upper surface of the sleeve. A locking shaft is fixedly connected to the sliding ring and the circumferential surface. A temperature monitoring gauge is fixedly connected to the inner surface of the top of the upper filter tank. A long cam is fixedly connected to the top of the main shaft. A motor is fixedly connected to the bottom of the main shaft, and the motor is fixedly connected to the lower surface of the lower filter tank. The sliding ring is slidably connected to the inner surface of the sleeve. The inner surface of the positioning rod and the movable locking block are in contact with each other. The inner surfaces of the fixed locking blocks are in contact with each other. A left and right spring is installed between the sliding ring and the fixed locking block. The inner surfaces of the locking shaft and the L-shaped through groove are in contact with each other. After wastewater is input into the lower and upper filter tanks, the mounting base is inserted into the limiting cylinder. The mounting base drives the U-shaped electric heating tube to be inserted into the lower and upper filter tanks. When filtering wastewater, the U-shaped electric heating tube is activated, heating the wastewater. During heating, the temperature monitoring gauge can monitor the temperature inside the lower and upper filter tanks in real time. The motor is started, driving the main shaft to rotate, which in turn drives the agitator to rotate, stirring the wastewater. After inserting the mounting base into the limiting cylinder, the positioning rod is pushed to the right, causing it to insert into the fixed and movable locking blocks. Rotate the positioning rod backward, causing the sliding ring to rotate, which in turn causes the locking shaft to rotate, inserting it into the right protruding end of the L-shaped through groove. This locks the sliding ring and positioning rod inside the sleeve. Once locked, the positioning rod also locks the fixed and movable locking blocks, allowing the mounting base to be quickly installed inside the limiting cylinder. When the U-shaped heating element needs to be inspected or replaced, rotate the positioning rod forward, causing the sliding ring and locking shaft to rotate forward. The locking shaft disengages from the right protruding end of the L-shaped through groove, causing the sliding ring and positioning rod to lose their lock. Then, the elastic reset action of the spring pushes the sliding ring and positioning rod to the left, displacing the fixed and movable locking blocks. This allows the mounting base to be quickly removed from the limiting cylinder.

[0006] Preferably, the stain discharge device includes a drain pipe, an annular support frame fixedly connected to the circumferential surface of the filter screen, a sludge collection cylinder fixedly connected to the left side of the inner wall of the lower filter tank, a scraper frame fixedly connected to the front side of the sludge collection cylinder, a solenoid valve fixedly connected to the lower surface of the drain pipe, and a U-shaped slide rod. An abutment ring is fixedly connected to the top circumferential surface of the U-shaped slide rod, a semi-circular block is fixedly connected to the top right end of the U-shaped slide rod, and a circular scraper is fixedly connected to the bottom right end of the U-shaped slide rod. A steel brush is fixedly connected to the bottom rear side of the sludge collection cylinder; a transmission sleeve shaft is fixedly connected to the upper surface of the long cam; the sludge discharge pipe is fixedly connected to the left side of the lower filter tank; the U-shaped slide rod is slidably connected to the left inner surface of the lower filter tank; a spring is provided between the contact ring and the left side of the lower filter tank; the U-shaped slide rod is slidably connected to the left inner surface of the sludge discharge pipe; the circular scraper is in contact with the inner surface of the sludge collection cylinder; the annular support frame is slidably connected to the inner wall of the lower filter tank; and the scraper frame is in contact with the upper surface of the filter screen. The steel brush and the upper surface of the filter screen come into contact with each other. After the sewage enters the lower and upper filter tanks, it passes through the filter screen. The pollutant particles and oil in the sewage are filtered and trapped above the filter screen. The main shaft drives the filter screen to rotate. When the filter screen rotates, its upper surface contacts the scraper frame. The scraper frame scrapes off the pollutants on the scraper frame and collects them in the collection cylinder. The main shaft drives the long cam to rotate. When the long cam rotates, its inclined surface and arc surface contact the semicircular block and push the semicircular block to the left. The semicircular block then drives the U-shaped slide rod and the contact ring to slide to the left. When the long cam... When the semicircular block is moved away from the semicircular block, the elastic restoring action of spring two pulls the contact ring to move to the right to reset. The contact ring then drives the U-shaped slide rod and the semicircular block to move to reset, which in turn causes the U-shaped slide rod to slide back and forth in the sewage pipe and the collection cylinder. The U-shaped slide rod then drives the circular scraper to move back and forth in the left and right and scrape the pollutants in the collection cylinder into the sewage pipe. After the sewage is filtered, the solenoid valve one is opened to discharge the pollutants from the device. When the filter screen rotates, it contacts the steel brush. The steel brush and the filter screen generate friction and scrape off the pollutant particles stuck in the filter screen mesh.

[0007] Preferably, the flocculant adding device includes a support frame, a conveying pipe fixedly connected to the inner surface of the support frame, a second solenoid valve fixedly connected to the top of the conveying pipe, and a feed hopper fixedly connected to the top of the second solenoid valve. The flocculant adding device also includes an annular discharge sleeve, a trapezoidal spreading box fixedly connected to the circumferential surface of the annular discharge sleeve, a material accumulation frame fixedly connected to the bottom inner surface of the trapezoidal spreading box, and a rotating push rod fixedly connected to the lower surface of the trapezoidal spreading box. The support frame is fixedly connected to the inner wall of the upper filter tank, the annular discharge sleeve is rotatably connected to the bottom end of the conveying pipe, the conveying pipe is fixedly connected to the top inner surface of the upper filter tank, the bottom end of the rotating push rod is in contact with the inner surface of the transmission sleeve shaft, and the upper surface of the annular discharge sleeve is in contact with the lower surface of the support frame. Flocculant is added to the feed hopper. When flocculant needs to be added during the filtration process, the device is opened... When solenoid valve two is activated, the flocculant falls from inside the valve into the feed pipe, and then enters the lower and upper filter tanks through the feed pipe. The flocculant can improve the flocculation efficiency of wastewater and gather floating matter in the wastewater. The flocculant enters the annular discharge sleeve through the feed pipe, and then enters the trapezoidal spreading box through the annular discharge sleeve. After entering the trapezoidal spreading box, the flocculant slides down the inclined side of the bottom of the trapezoidal spreading box away from the feed pipe. When the flocculant in the trapezoidal spreading box accumulates to the top of the collection frame, it can fall from the collection frame into the wastewater for flocculation. The rotation of the long cam drives the transmission sleeve shaft to rotate around the main shaft axis. The transmission sleeve shaft drives the rotating push rod to rotate around the circumference. The rotating push rod drives the trapezoidal spreading box and the annular discharge sleeve to rotate on the feed pipe. During the rotation, the trapezoidal spreading box sprinkles the flocculant into the wastewater, increasing the dispersion area and further promoting the uniformity and efficiency of mixing wastewater and flocculant.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This industrial wastewater high-efficiency filtration treatment device uses a U-shaped electric heating tube to heat the wastewater, promoting pollutant decomposition and separating oily substances. During the heating process, a temperature monitoring gauge can monitor the temperature inside the lower and upper filter tanks in real time, facilitating precise temperature control and gradient heating to improve pollutant decomposition efficiency. The stirring paddle agitates the wastewater, promoting its flowability and improving the uniformity of heating, thus enhancing the pollutant decomposition effect. The elastic reset action of the spring pushes the sliding ring and positioning rod to the left, displacing the fixed and movable locking blocks. This allows the mounting base to be quickly removed from the limiting cylinder, improving the convenience of U-shaped electric heating tube inspection and replacement.

[0010] 2. This industrial wastewater high-efficiency filtration treatment device uses a main shaft to drive the filter screen to rotate. When the filter screen rotates, its upper surface contacts the scraper frame. The scraper frame scrapes off the pollutants on the scraper frame and collects them in the collection cylinder, preventing pollutants from accumulating above the filter screen and causing a decrease in filtration efficiency.

[0011] 3. This industrial wastewater high-efficiency filtration treatment device uses a U-shaped slide bar to drive a circular scraper to move back and forth, scraping pollutants in the collection cylinder into the discharge pipe. After the wastewater is filtered, the solenoid valve is opened to discharge the pollutants, thus improving the pollutant treatment efficiency. The steel brush and the filter screen generate friction and scrape off the pollutant particles stuck in the filter screen holes, preventing the filter screen from clogging and further improving the filtration efficiency.

[0012] 4. This industrial wastewater high-efficiency filtration treatment device opens the second solenoid valve, and the flocculant falls from the second solenoid valve into the conveying pipe, and then enters the lower filter and upper filter through the conveying pipe. The flocculant can improve the flocculation efficiency of wastewater, gather the floating matter in the wastewater, improve the filtration effect, and facilitate the treatment of pollutants.

[0013] 5. This industrial wastewater high-efficiency filtration treatment device allows flocculants in the trapezoidal spreading box to accumulate at the top of the collection frame and fall into the wastewater for flocculation, increasing the spreading area and improving the mixing efficiency of flocculants and wastewater, thereby enhancing flocculation efficiency. The rotating push rod drives the trapezoidal spreading box to rotate and spread the flocculants into the wastewater, further promoting the uniformity and efficiency of mixing wastewater and flocculants.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-8One embodiment of the present invention is as follows: a high-efficiency industrial wastewater filtration treatment device includes a lower filter tank 1, an upper filter tank 2 connected to the upper surface of the lower filter tank 1 via a flange, a limiting cylinder 3 fixedly connected to the upper surface of the upper filter tank 2, a mounting base 4 sleeved on the inner surface of the limiting cylinder 3, and a U-shaped electric heating tube 5 fixedly connected to the lower surface of the mounting base 4. The U-shaped electric heating tube 5 can heat the wastewater to promote the decomposition of pollutants and separate oily substances. During the heating process, a temperature monitoring gauge 6 can monitor the internal temperature of the lower filter tank 1 and the upper filter tank 2 in real time, facilitating precise temperature control and gradient heating. This design improves the efficiency of pollutant decomposition. A stain discharge device 7 for convenient discharge of inorganic pollutants is installed on the left side of the lower filter tank 1. A flocculant addition device 8 for uniformly adding flocculant is installed on the top of the upper filter tank 2. A main shaft 9 is rotatably connected to the inner surface of the bottom end of the lower filter tank 1. An agitator 10 is fixedly connected to the circumferential surface of the main shaft 9. A filter screen 11 is fixedly connected to the circumferential surface of the main shaft 9. A movable locking block 13 is fixedly connected to the lower top surface of the mounting base 4. A fixing block 14 is fixedly connected to the circumferential surface of the limiting cylinder 3. A sleeve 15 is fixedly connected to the left side of the fixing block 14. A positioning rod 16 is slidably connected to the inner surface of the left end of sleeve 15. A sliding ring 17 is fixedly connected to the circumferential surface of the positioning rod 16. An L-shaped through groove 18 is opened on the upper surface of sleeve 15. A retaining pin 19 is fixedly connected to the sliding ring 17 and the circumferential surface. A temperature monitoring gauge 6 is fixedly connected to the inner surface of the top of upper filter vessel 2. A long cam 12 is fixedly connected to the top of main shaft 9. A motor is fixedly connected to the bottom of main shaft 9, and the motor is fixedly connected to the lower surface of lower filter vessel 1. The sliding ring 17 is slidably connected to the inner surface of sleeve 15. The inner surfaces of positioning rod 16 and movable retaining block 13 are in contact with each other. The positioning rod 16 and fixed retaining block 13 are in contact with each other. The inner surfaces of the sliding ring 17 and the fixed block 14 are in contact with each other. A left and right spring is set between the sliding ring 17 and the fixed block 14. The inner surfaces of the locking shaft 19 and the L-shaped through groove 18 are in contact with each other. The stirring paddle 10 stirs the sewage, promotes the flow of sewage, and thus improves the uniformity of sewage heating and improves the decomposition effect of pollutants. The elastic reset action of the spring pushes the sliding ring 17 and the positioning rod 16 to the left to push out the fixed block 14 and the movable block 13, thereby separating the fixed block 14 and the movable block 13. At this time, the mounting base 4 can be quickly removed from the limiting cylinder 3, which improves the convenience of inspection and replacement of the U-shaped electric heating tube 5.

[0025] Working Principle: After wastewater is fed into the lower filter tank 1 and the upper filter tank 2, the mounting base 4 is inserted into the limiting cylinder 3. The mounting base 4 drives the U-shaped electric heating tube 5 into the lower filter tank 1 and the upper filter tank 2. When filtering wastewater, the U-shaped electric heating tube 5 is activated, which heats the wastewater to promote the decomposition of pollutants and separate oily substances. During the heating process, the temperature monitoring gauge 6 can monitor the internal temperature of the lower filter tank 1 and the upper filter tank 2 in real time, facilitating precise temperature control and gradient heating to improve the efficiency of pollutant decomposition. The motor is started, which drives the main shaft 9 to rotate. The main shaft 9 drives the agitator 10 to rotate, which agitates the wastewater, promoting its flowability and improving the uniformity of heating, thus enhancing the pollutant decomposition effect. After inserting the mounting base 4 into the limiting cylinder 3, the positioning rod 16 is pushed to the right, causing it to insert into the fixed block 14 and the movable block 13. At this time, the positioning rod 16 is rotated backward. The positioning rod 16 drives the sliding ring 17 to rotate, and the sliding ring 17 drives the locking shaft 19 to rotate, so that the locking shaft 19 is inserted into the right protruding end of the L-shaped through groove 18, thereby locking the sliding ring 17 and the positioning rod 16 in the sleeve 15. After the positioning rod 16 is locked, it can lock the fixed locking block 14 and the movable locking block 13, thereby quickly installing the mounting base 4 in the limiting cylinder 3. When it is necessary to inspect and replace the U-shaped heating tube 5, the positioning rod 16 is rotated forward, and the positioning rod 16 drives the sliding ring 17 and the locking shaft 19 to rotate forward. The locking shaft 19 disengages from the right protruding end of the L-shaped through groove 18, so that the sliding ring 17 and the positioning rod 16 are unlocked. Then, the elastic reset action of the spring 1 pushes the sliding ring 17 and the positioning rod 16 to the left to push out the fixed locking block 14 and the movable locking block 13, thereby separating the fixed locking block 14 and the movable locking block 13. At this time, the mounting base 4 can be quickly removed from the limiting cylinder 3, further improving the convenience of inspecting and replacing the U-shaped heating tube 5.

[0026] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the stain discharge device 7 includes a drain pipe 71, an annular support frame 72 is fixedly connected to the circumferential surface of the filter screen 11, a sludge collection cylinder 73 is fixedly connected to the left side of the inner wall of the lower filter tank 1, a scraper frame 74 is fixedly connected to the front side of the sludge collection cylinder 73, a solenoid valve 75 is fixedly connected to the lower surface of the drain pipe 71, the main shaft 9 drives the filter screen 11 to rotate, and when the filter screen 11 rotates, its upper surface contacts the scraper frame 74. 4. The contaminants on the scraper frame 74 are scraped off and collected in the collection cylinder 73 to prevent contaminants from accumulating above the filter screen 11 and causing a decrease in filtration efficiency. The stain discharge device 7 also includes a U-shaped slide bar 76. An abutment ring 77 is fixedly connected to the top circumferential surface of the U-shaped slide bar 76. A semi-circular block 78 is fixedly connected to the top right end of the U-shaped slide bar 76. A circular scraper 79 is fixedly connected to the bottom right end of the U-shaped slide bar 76. A steel brush 710 is fixedly connected to the bottom rear side of the collection cylinder 73. A long cam 1 A transmission sleeve shaft 711 is fixedly connected to the upper surface of the filter 2. The sewage pipe 71 is fixedly connected to the left side of the lower filter tank 1. The U-shaped slide rod 76 is slidably connected to the inner left side of the lower filter tank 1. A spring 2 is provided between the contact ring 77 and the left side of the lower filter tank 1. The U-shaped slide rod 76 is slidably connected to the inner left end of the sewage pipe 71. The circular scraper 79 is in contact with the inner surface of the sludge collection cylinder 73. The annular support frame 72 is slidably connected to the inner wall of the lower filter tank 1. The scraper frame 74 is in contact with the upper surface of the filter screen 11. The steel brush 710 is in contact with the upper surface of the filter screen 11. The U-shaped slide rod 76 then drives the circular scraper 79 to move back and forth and scrape the pollutants in the sludge collection cylinder 73 into the sewage pipe 71. After the sewage is filtered, the solenoid valve 75 is opened to discharge the pollutants from the device, which improves the pollutant treatment efficiency. The steel brush 710 generates friction with the filter screen 11 and scrapes off the pollutant particles stuck in the mesh of the filter screen 11, preventing the filter screen 11 from clogging and further improving the filtration efficiency.

[0027] Working principle: After sewage enters the lower filter tank 1 and the upper filter tank 2, it passes through the filter screen 11. Pollutant particles and oil in the sewage are filtered and placed above the filter screen 11. The main shaft 9 drives the filter screen 11 to rotate. When the filter screen 11 rotates, its upper surface contacts the scraper frame 74. The scraper frame 74 scrapes off the pollutants on the scraper frame 74 and collects them in the collection cylinder 73, preventing pollutants from accumulating above the filter screen 11 and reducing the filtration effect. The main shaft 9 drives the long cam 12 to rotate. When the long cam 12 rotates, its inclined surface and arc surface contact the semicircular block 78 and push the semicircular block 78 to the left. The semicircular block 78 then drives the U-shaped slide rod 76 and the contact ring 77 to slide to the left. When the long cam 12 moves away from the semicircular block 78, the spring 2... The elastic reset action pulls the contact ring 77 to move to the right to reset. The contact ring 77 then drives the U-shaped slide rod 76 and the semi-circular block 78 to move and reset, thereby causing the U-shaped slide rod 76 to slide back and forth in the sewage pipe 71 and the collection cylinder 73. The U-shaped slide rod 76 then drives the circular scraper 79 to move back and forth in the left and right and scrape the pollutants in the collection cylinder 73 into the sewage pipe 71. After the sewage is filtered, the solenoid valve 75 is opened to discharge the pollutants from the device, which improves the pollutant treatment efficiency. When the filter screen 11 rotates, it contacts the steel brush 710. The steel brush 710 and the filter screen 11 generate friction and scrape off the pollutant particles stuck in the mesh of the filter screen 11, preventing the filter screen 11 from clogging and further improving the filtration efficiency.

[0028] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the flocculant adding device 8 includes a support frame 81, a conveying pipe 82 fixedly connected to the inner surface of the support frame 81, a solenoid valve 83 fixedly connected to the top end of the conveying pipe 82, and a feed hopper 84 fixedly connected to the top end of the solenoid valve 83. When the solenoid valve 83 is opened, the flocculant falls from the solenoid valve 83 into the conveying pipe 82, and then enters the lower filter tank 1 and the upper filter tank 2 through the conveying pipe 82. The flocculant can improve the flocculation efficiency of sewage, gather floating matter in sewage, improve the filtration effect, and facilitate the treatment of pollutants. The flocculant adding device 8 also includes an annular feeding sleeve 85, a trapezoidal spreading box 86 fixedly connected to the circumferential surface of the annular feeding sleeve 85, and an accumulation box 86 fixedly connected to the bottom inner surface of the trapezoidal spreading box 86. A rotating push rod 88 is fixedly connected to the lower surface of the material frame 87 and the trapezoidal feeding box 86. The support frame 81 is fixedly connected to the inner wall of the upper filter vessel 2. The annular feeding sleeve 85 is rotatably connected to the bottom end of the conveying pipe 82. The conveying pipe 82 is fixedly connected to the inner surface of the top end of the upper filter vessel 2. The bottom end of the rotating push rod 88 is in contact with the inner surface of the transmission sleeve shaft 711. The upper surface of the annular feeding sleeve 85 is in contact with the lower surface of the support frame 81. When the flocculant in the trapezoidal feeding box 86 accumulates to the top of the accumulation frame 87, it can fall from the accumulation frame 87 into the sewage for flocculation, which increases the feeding area and improves the mixing efficiency of the flocculant and sewage, thereby improving the flocculation efficiency. The rotating push rod 88 drives the trapezoidal feeding box 86 to rotate and feed the flocculant into the sewage, which further promotes the uniformity and efficiency of the mixing of sewage and flocculant.

[0029] Working principle: Flocculant is added to the feed hopper 84. When flocculant needs to be added during the filtration process, solenoid valve 2 83 is opened, and the flocculant falls from solenoid valve 2 83 into the conveying pipe 82. Then, it enters the lower filter tank 1 and the upper filter tank 2 through the conveying pipe 82. The flocculant can improve the flocculation efficiency of sewage, gather the floating matter in the sewage, improve the filtration effect, and facilitate the treatment of pollutants. The flocculant enters the annular discharge sleeve 85 through the conveying pipe 82, and then enters the trapezoidal spreading box 86 through the annular discharge sleeve 85. After entering the trapezoidal spreading box 86, the flocculant flows away from the conveying pipe 82 through the inclined bottom of the trapezoidal spreading box 86. As the flocculant in the trapezoidal spreading box 86 accumulates to the top of the collection frame 87, it can fall from the collection frame 87 into the sewage for flocculation, increasing the spreading area and improving the mixing efficiency of the flocculant and sewage, thereby improving the flocculation efficiency. The rotation of the long cam 12 drives the transmission sleeve shaft 711 to rotate around the axis of the main shaft 9. The transmission sleeve shaft 711 drives the rotating push rod 88 to rotate around the axis. The rotating push rod 88 drives the trapezoidal spreading box 86 and the annular discharge sleeve 85 to rotate on the conveying pipe 82. During the rotation, the trapezoidal spreading box 86 spreads the flocculant into the sewage, increasing the spreading area and further promoting the uniformity and efficiency of the mixing of sewage and flocculant.
