Description
Technical Field
[0001] This invention belongs to the technical field of water supply devices, specifically relating to a filtration device for a mixing reaction tank. Background Technology
[0002] Urban water supply sources are mainly divided into two categories: surface water and groundwater. Surface water refers to water bodies in rivers, lakes, reservoirs, and oceans, while groundwater refers to well water, spring water, and underground river water. In the water treatment process, a mixing reaction tank is set up. After the water enters the mixing reaction tank, flocculants are added, causing impurities in the water to settle. However, in summer, there is a high algae population in the water. When using filter plates, algae easily clog the filter pores. Solid impurities and suspended solids in the water gradually accumulate on the surface and in the pores of the filter plates, reducing filtration efficiency. Severe clogging can even damage the filter plates, shortening their lifespan and increasing equipment maintenance costs and replacement frequency. Furthermore, when treating groundwater, due to soil pollution, groundwater often contains chemical pollutants such as antibiotics. Using only flocculants and filter plates is insufficient to achieve effective water purification. Therefore, existing technologies require further improvement. Summary of the Invention
[0003] The purpose of this invention is to provide a mixed reaction tank filtration device that prevents clogging of filter holes, can adsorb antibiotics and chemical pollutants in water, and can slowly release bacteria for water purification.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A filtration device for a mixing reaction tank includes a sleeve, with an inlet head fixedly connected to the upper end of the sleeve. The inlet head has an inlet port. A first filter cylinder is disposed inside the sleeve, with the upper end of the first filter cylinder extending out of the upper end of the sleeve and detachably connected to the inlet head. The lower end opening of the sleeve and the lower end opening of the first filter cylinder are detachably sealed by a rubber ring. A cleaning ring is provided between the sleeve and the first filter cylinder for cleaning the outer wall of the first filter cylinder. The cleaning ring is connected to several hydraulic cylinders. The rubber ring has a first through hole through which the telescopic rod of the hydraulic cylinder passes. The base of the hydraulic cylinder is located below the sleeve and connected to a fixed seat. The telescopic rod of the hydraulic cylinder passes through the first through hole and is connected to the cleaning ring. A fixed ring is sleeved on the lower end of the sleeve. A screw is slidably sleeved on the fixed ring. The lower end of the screw is connected to the fixed seat. The screw and nut cooperate to form a structure in which the distance between the fixed ring and the fixed seat is adjustable.
[0005] Furthermore, a water-blocking ring is fixedly fitted on the inner side wall of the upper end of the sleeve, and the water-blocking ring is provided with several water inlets. The water inlet is connected to the water inlet. The outer side wall of the upper part of the sleeve is also provided with a medicine inlet. The first filter cylinder is slidably fitted inside the water-blocking ring.
[0006] Furthermore, the bottom of the first filter cylinder is sealed by a base plate, and the base plate is provided with a water outlet.
[0007] Furthermore, the first filter cylinder is provided with a second filter cylinder, which is made of metal mesh. The lower opening of the second filter cylinder is covered with metal mesh. The second filter cylinder is evenly divided into several honeycomb-shaped vertical cylinders by a dividing mesh. The length direction of the cylinders is the same as that of the first and second filter cylinders. A removable microbial culture slow-release box is provided inside the cylinder.
[0008] Furthermore, the microbial culture slow-release box is made of metal mesh, the mesh openings of which are sealed with a polyvinyl alcohol film. The microbial culture slow-release box is divided into an upper lid and a lower body, which can be detached and opened / closed by threads.
[0009] Furthermore, the water inlet head includes a fixed cylinder, the upper end of which is closed by a sealing plate, and the water inlet is located on the outer wall of the fixed cylinder. The sealing plate is also provided with a lifting handle. A stabilizing plate is fixedly sleeved on the lower opening of the fixed cylinder. The stabilizing plate is provided with a fixing hole. The lower end of the fixed cylinder is connected to the upper end of the sleeve. The side wall of the fixed cylinder is provided with a water inlet. The sealing plate is provided with a first groove and the inner side wall of the first groove is provided with an internal thread. The upper end of the first filter cylinder is provided with an external thread that cooperates with the internal thread of the first groove of the sealing plate, forming a detachable structure between the first filter cylinder and the water inlet head.
[0010] Furthermore, the sleeve and the first filter cylinder are cylindrical, and the transverse axial surfaces of the water-blocking ring and the cleaning ring are circular. The circular axial surfaces of the sleeve, the first filter cylinder, and the cleaning ring are parallel to the circular axial surface of the water-blocking ring, and the inner annular edge of the water-blocking ring abuts against the outer wall of the first filter cylinder.
[0011] Furthermore, the cleaning ring is a metal ring body, the outer wall of the circular axial surface of the cleaning ring is tightly fitted with the inner wall of the sleeve, and several second grooves are evenly distributed on the inner wall of the circular axial surface of the cleaning ring. A cleaning head is provided in the second groove, and the cleaning head abuts against the outer wall of the first filter cartridge.
[0012] Furthermore, the fixed base is provided with a positioning plate, which has several second through holes and several positioning rods. The length direction of the positioning rods is perpendicular to the surface of the positioning plate, and the fixed base is provided with several third through holes for the positioning rods to pass through.
[0013] Furthermore, a sliding plate is provided on the bottom plate at the lower end of the first filter cylinder. One end of the sliding plate is rotatably connected to the bottom plate, and the other end of the sliding plate can be rotated to the lower opening of the sleeve, forming a structure that can prevent the rubber ring from falling off.
[0014] The filtration device of this invention mixes water and flocculant within the device. After the flocculant and water are mixed, some flocculents, gravel, algae, and other impurities are trapped between the sleeve and the first filter cylinder, facilitating the later collection of impurities from the mixing reaction tank. Simultaneously, by controlling the hydraulic cylinder to retract up and down, the cleaning ring can move up and down along the length of the first filter cylinder, removing impurities or algae attached to the outer wall of the first filter cylinder to prevent affecting its filtration effect. A second filter cylinder is provided inside the first filter cylinder. The straight cylinder inside the second filter cylinder can be filled with activated carbon, which can adsorb antibiotics and chemical pollutants after water purification. This invention also includes a microbial slow-release box. The mesh of the microbial slow-release box is sealed with a polyvinyl alcohol film, which can slowly release microorganisms. When the microbial slow-release box is not needed, it can be directly removed. When activated carbon is not needed, the second filter cylinder can be removed.
[0015] This invention uses a lifting method, which allows the filter device to be lifted up along the length of the positioning rod. During installation, the filter device can be positioned simply by inserting the positioning rod into the third through hole of the fixing base. Disassembly and installation are convenient, and the internal rubber ring and first filter cylinder can be disassembled and cleaned easily. Attached Figure Description

The upper surface of the sealing plate 202 is also provided with a lifting handle 203. A stabilizing plate is fixedly sleeved on the lower opening of the fixed cylinder 205. The stabilizing plate is provided with a fixing hole 20. If the water volume is too large, it can be fixed to the side wall of the mixing reaction tank through the fixing hole. If the water volume is normal, it does not need to be used. The fixing hole 20 is a spare hole. The lower end of the fixed cylinder 205 is connected to the upper end of the sleeve 1. The side wall of the fixed cylinder 205 is provided with a water inlet 201. The lower surface of the sealing plate 202 is provided with a first groove 206 and the inner side wall of the first groove 206 is provided with an internal thread. The upper end of the first filter cylinder 19 is provided with an external thread that cooperates with the internal thread of the first groove 206 of the sealing plate 202, forming a detachable structure between the first filter cylinder 19 and the water inlet head 2. Both the first filter cylinder 19 and the second filter cylinder 12 are cylindrical. The transverse axial surfaces of the water-blocking ring 3 and the cleaning ring 6 are circular. The circular axial surfaces of the sleeve 1, the first filter cylinder 19, and the cleaning ring 6 are parallel to the circular axial surface of the water-blocking ring 3. The inner annular edge of the water-blocking ring 3 abuts against the outer wall of the first filter cylinder 19. The cleaning ring 6 is a metal ring. The outer wall of the circular axial surface of the cleaning ring 6 is tightly fitted with the inner wall of the sleeve 1. Several second grooves 601 are evenly distributed on the inner wall of the circular axial surface of the cleaning ring 6. A cleaning head 602 is provided in the second groove 601. The cleaning head 602 is a brush and abuts against the outer wall of the first filter cylinder 19. The fixed base 16 is provided with a positioning plate 18. The positioning plate 18 has several second through holes 181 and several positioning rods 182. The length direction of the positioning rods 182 is perpendicular to the plate surface of the positioning plate 18. The fixed base 16 has several third through holes 161 for the positioning rods 182 to pass through. The bottom plate 191 at the lower end of the first filter cylinder 19 is provided with a sliding plate 192. One end of the sliding plate 192 is rotatably connected to the bottom plate 191 through a rotating bearing 193. The other end of the sliding plate 192 can be rotated to the lower opening of the sleeve 1, forming a structure that can prevent the rubber ring 5 from falling off.
[0018] In use, first open the upper box cover 151 and the lower box body 152, pour the bacterial powder into the lower box body 152, and close the upper box cover 151 and the lower box body 152. Then place the bacterial slow-release box 15 into the straight cylinder 14, and then place the second filter cylinder 12 into the first filter cylinder 19. Next, insert the first filter cylinder 19 into the sleeve 1 through the lower opening of the sleeve 1. Then thread the upper end of the first filter cylinder 19 to the sealing plate 202. Then use the rubber ring 5 to seal the gap between the first filter cylinder 19 and the lower end of the sleeve 1. After rotating the sliding plate 192, rotate the sliding plate 192 to below the rubber ring 5 to prevent the rubber ring 5 from falling off. Finally, connect the water inlet 201 to the water inlet pipe of the mixing reaction tank. Water enters the gap between the sleeve 1 and the first filter cylinder 19 through the inlet 201 and the outlet 301. Flocculant and other agents are introduced through the inlet. The flocculated water then passes through the filter holes of the first filter cylinder 19 through the gap and enters the first filter cylinder 19. The filter holes filter out some large particles of sand, gravel and algae and other impurities in the gap between the sleeve 1 and the first filter cylinder 19. The filtered water then enters the first filter cylinder 19 through the filter holes.
[0019] At this point, if groundwater filtration is required, activated carbon can be added to the straight cylinder 14 of the second filter cartridge 12. Activated carbon has an adsorption effect on antibiotics and chemical pollutants in groundwater, which can reduce antibiotics and chemical pollutants in the water. When it is necessary to add bacteria, remove the activated carbon in the straight cylinder 14, rotate the bacteria release box 15, place the bacteria in the bacteria release box 15, and then place the bacteria release box 15 in the straight cylinder 14. As the polyvinyl alcohol film on the bacteria release box 15 at the water contact port continuously dissolves, the bacterial powder is continuously released. At this time, fix the positioning plate 18 at the bottom of the mixing reaction tank, insert the positioning rod 182 through the third through hole 161, and insert the fixing seat 16 into the positioning plate 18. During use, the extension and retraction of the hydraulic cylinder can also be controlled to move the cleaning ring 6 up and down. The cleaning head 602 of the cleaning ring 6 rubs the outer wall of the first filter cartridge 19 to remove impurities attached to the outer wall of the first filter cartridge 19, preventing impurities from clogging the outer wall of the first filter cartridge.
[0020] After a period of use, if the filter needs to be cleaned, simply disconnect the inlet pipe from the inlet 201, then use the pull handle 203 to pull upwards. The filter will move vertically upwards. Then remove the filter, remove the nut 901 above the fixing ring 9, remove the sleeve 1 upwards, rotate the sliding plate 192, and pull the pull handle 203 to pull the sleeve 1 upwards. The cleaning ring 6 will be pulled out from the lower opening of the sleeve 1. Rotate the first filter cylinder 19 to separate the first filter cylinder 19 from the inlet head 2. The second filter cylinder 12 and the microbial slow release box 15 inside the first filter cylinder can be cleaned and replaced.
[0021] After cleaning, connect the first filter cartridge 19 and the water inlet head 2, then insert the cleaning ring 6 between the sleeve 1 and the first filter cartridge 19. The rubber ring 5 seals the lower end of the sleeve 1 and the first filter cartridge 19. Move the sliding plate 192. After moving, one end of the sliding plate 192 is located on the bottom plate of the first filter cartridge, and the other end of the sliding plate 192 is in contact with the lower opening of the sleeve 1, preventing the rubber ring 5 from falling off from the lower end of the sleeve 1. Then, hold the lifting handle 203 and align the third through hole 161 with the positioning rod 182. Insert the positioning rod 182 into the third through hole 161. Connect the water inlet pipe to the water inlet 201 and start water intake.
