Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1, referring to Figure 1-2 A water purification and filtration device includes a filter box 1 and a drain pipe disposed at the lower end of the filter box 1. A baffle 12 is provided in the middle of the filter box 1. A tube 6 is rotatably provided in the middle of the baffle 12. A water inlet 7 is provided in the circumferential position of the tube 6. The bottom of the tube 6 extends to the bottom of the baffle 12 and a water outlet 25 is provided at the bottom of the tube 6. A material exchange structure is provided between the lower end of the tube 6 and the baffle 12. The material exchange structure includes exchange holes 10 arranged in a ring array at the lower end of the tube 6. The same number of discharge holes 11 are provided on the inner side of the baffle 12. When the tube 6 rotates to a certain position, the exchange holes 10 and the discharge holes 11 are connected to each other one by one. The discharge holes 11 are arranged in a fan shape, and the cross-sectional dimension of the inner side of the discharge holes 11 gradually increases towards the position away from the exchange holes 10. At the same time, the discharge holes 11 are inclined.

[0028] The bottom of the discharge hole 11 is evenly provided with several drainage holes 13, and the lower end of the drainage holes 13 is connected to the area below the partition plate 12.

[0029] A container 3 is provided at the upper end of the tube body 6. Both the tube body 6 and the container 3 are filled with activated carbon granules. The container 3 is fixed above the filter box 1 by a connecting rod 2. The bottom of the container 3 is provided with an annular folded edge 30, and the upper part of the tube body 6 extends to the folded edge 30 and fits against the bottom of the container 3. The bottom of the container 3 is provided with a plurality of first conveying holes 4 in an annular shape. (Refer to...) Figure 7 The top of the tube body 6 is provided with a second conveying hole 5 in an annular shape, and the second conveying hole 5 corresponds one-to-one with the first conveying hole 4.

[0030] The interior of the container 3 and the upper part of the partition 12 are both recessed towards the center. A groove 8 is provided at the middle of the upper part of the partition 12. An annular plate 9 is installed on the outside of the tube body 6 and is locked inside the groove 8.

[0031] When wastewater needs to be treated, the wastewater is injected into the filter box 1. The wastewater entering the filter box 1 enters through the water inlet 7 on the outside of the pipe body 6. These water inlet 7 are all located above the partition plate 12. The wastewater enters the pipe body 6 through the water inlet 7 and comes into contact with the activated carbon particles inside the pipe body 6. Then the water is discharged from the water outlet 25 at the bottom of the pipe body 6. During the contact process, due to the porous characteristics of the activated carbon surface, suspended solids and other impurities are adsorbed. When a filter membrane is used to filter suspended solids, it will cause the filter membrane to become clogged in a very short time. Therefore, activated carbon particles are used for filtration and adsorption.

[0032] After the activated carbon particles inside the tube 6 have been filtered for a period of time, the adsorption sites on their surface will decrease compared to the initial stage. At this time, the position of the tube 6 is rotated by mechanical transmission. During the rotation of the tube 6, the outer annular plate is always located inside the annular groove 8, indirectly supporting the tube 6. Initially, the positions of the first conveying hole 4 and the second conveying hole 5 at the bottom of the container 3 do not coincide, and the positions of the lower exchange hole 10 and the discharge hole 11 also do not coincide. However, after the tube 6 rotates a certain angle, the positions of the first conveying hole 4 and the second conveying hole 5 coincide, and the positions of the exchange hole 10 and the discharge hole 11 also coincide. At this time, the activated carbon particles in the container 3 will pass through the first conveying hole 4 and the second conveying hole 5. The conveying hole 5 enters the interior of the tube body 6, and the activated carbon particles located at the lower end of the tube body 6 pass through the exchange hole 10 and enter the discharge hole 11. This replenishes the interior of the tube body 6 with unused activated carbon particles and discharges the activated carbon particles at the bottom. The discharge hole 11 is set at an angle downwards, and the size of the end gradually increases, so that the activated carbon particles in the discharge hole 11 will not clog. Secondly, during this process, a small amount of water will enter the discharge hole 11 along with the activated carbon particles. The drain hole 13 located in the discharge hole 11 then plays its role, draining some of the water back into the filter box 1 below the partition 12. The overlap time between the first conveying hole 4 and the second conveying hole 5 is controlled according to the number of activated carbon particles that need to be added.

[0033] Example 2, Reference Figure 5-6 The difference between this embodiment and Embodiment 1 is that a particle processing structure is further provided below the tube body 6. The particle processing structure includes a motor 22 installed at the bottom of the filter box 1. The output shaft of the motor 22 is connected to a rotating shaft 21. A connecting seat 29 is provided above the rotating shaft 21. Several plates 24 are provided around the connecting seat 29. (Refer to...) Figure 8Each end of the plate 24 is fixed with a bracket 17, which is arranged in a ring. A filter 15 is placed inside the bracket 17, and the upper part of the filter 15 is a ring plate structure. A microfiltration membrane is laminated on the inner wall of the filter 15, and multiple filter 15s can be moved sequentially to the bottom of the tube 6.

[0034] refer to Figure 1-2 The filter box 1 also has a square hole 23 on its side wall. When the filter hopper 15 is being adjusted, it can pass through the square hole 23 and move to the outside of the filter box 1.

[0035] A second transmission tooth 20 is connected above the connecting seat 29 via a transmission shaft, and a first transmission tooth 18 is provided at the lower outer end of the tube body 6. A chain 19 is sleeved between the first transmission tooth 18 and the second transmission tooth 20.

[0036] During the addition and discharge of activated carbon particles, the tube 6 rotates. The activated carbon particles inside, through contact and friction with the impeller 28, tear apart some cyanobacteria. The resulting cyanobacteria particles are washed down with the water flow. Therefore, an adjustable bracket 17 is installed below the tube 6. The bracket 17 is annular, and a filter bucket 15 is placed inside it. The upper edge of the filter bucket 15 extends horizontally outward, allowing it to fit perfectly within the bracket 17. The center of the filter bucket 15 is concave, and a microfiltration membrane is laminated to its surface. These microfiltration membranes allow water to pass through quickly while simultaneously trapping small cyanobacteria particles. Because the suspended matter has been adsorbed by the activated carbon, the suspended... The problem of the material not clogging the microfiltration membrane in a short time is addressed. Secondly, through the cooperation between the first transmission gear 18, the chain 19, and the second transmission gear 20, the synchronous movement of the circular tube 6 and multiple filter hoppers 15 is achieved. One cycle is defined as one feeding and unloading operation into the tube 6, that is, from the point where the first conveying hole 4 and the second conveying hole 5 coincide to the next point where they coincide. During this cycle, the filter hopper 15 below the tube 6 moves away, and the adjacent filter hopper 15 appears below the tube 6 and stops moving. Since there is an interval in the feeding process, the tube 6 and the motor 22 also operate intermittently. Therefore, the filter hopper 15 will stay below the tube 6 for a period of time to collect the broken blue-green algae particles.

[0037] A square hole 23 is provided on the outer wall at the lower end of the filter box 1. When the filter hopper 15 rotates, each filter hopper 15 will pass through the square hole 23 and appear outside the filter box 1 at a certain moment. At this time, the operator can observe the situation inside the filter hopper 15 to consider whether to replace it, and the replacement can be carried out without stopping the machine.

[0038] Example 3, Reference Figure 3-4The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a round shaft 26 is fixed at the bottom of the container 3, the round shaft 26 extends into the interior of the tube 6, a spiral impeller 28 is provided on the outer side of the round shaft 26, and a number of protrusions 27 are provided on the surface of the impeller 28.

[0039] A top cover is provided on the top of the container 3 for adding material. At the same time, the round shaft 26 at the lower end of the container 3 extends into the interior of the tube 6, and a spiral impeller 28 is provided on the outside of the round shaft 26. The impeller 28 has a reserved hole to facilitate the smooth flow of water. When the tube 6 rotates, there will be relative rotation between it and the impeller 28. During the contact process, it is beneficial to discharge the material at the bottom. Due to the water flowing from top to bottom for a period of time, the activated carbon particles will be in closer contact. With the relative rotation between the impeller 28 and the tube 6, the gap between the activated carbon particles can be readjusted, which can solve the problem of the water flow rate decreasing due to the smaller gap between the activated carbon particles. Secondly, the protrusions 27 on the impeller 28 help to turn the activated carbon particles during the contact process, further adjusting the gap between the particles.

[0040] Example 4, Reference Figure 6 The difference between this embodiment and embodiments 1, 2 and 3 is that a pin assembly 14 is provided at the lower outer end of the tube body 6. The pin assembly 14 includes a bracket 1401, a limiting plate 1402, a pin rod 1403 and a through hole 1404.

[0041] The bracket 1401 is installed on the lower outer side of the tube body 6. The through hole 1404 is located at the bottom of the bracket 1401. The limiting plate 1402 is fixed at the top of the pin rod 1403. The pin rod 1403 slides in the through hole 1404. The upper end of the filter hopper 15 is provided with a positioning hole 16. When the filter hopper 15 is moved to the bottom of the tube body 6, the bottom of the pin rod 1403 extends to the inside of the positioning hole 16. The bottom of the pin rod 1403 is spherical.

[0042] On both sides of the tube body 6, there are pin assemblies 14 consisting of a bracket 1401, a limiting plate 1402, a pin rod 1403, and a through hole 1404. When there is no filter funnel 15 below the pin rod 1403, it will hang down naturally, and the limiting plate 1402 will fit against the inner side of the bracket 1401. When the filter funnel 15 gradually moves towards the lower end of the tube body 6, the bottom of the pin rod 1403 contacts the upper end of the filter funnel 15. Since the bottom of the pin rod 1403 is spherical, the pin rod 1403 will move from the upper side of the filter funnel 15 to the upper end of the funnel 15. Until the filter bucket 15 stops moving, the bottom of the pin rod 1403 is inserted into the positioning hole 16 provided at the upper end of the filter bucket 15. This is because the filter bucket 15 vibrates laterally during contact with the water flow. This setting can limit the lateral vibration of the filter bucket 15. The inner side of the positioning hole 16 is also hemispherical. When the filter bucket 15 continues to move, the ball at the bottom of the pin rod 1403 can smoothly come out of the positioning hole 16. The bracket 1401 is horizontally placed in a U-shape and will not come into contact with the moving chain 19.

[0043] The first transmission gear 18, the bracket 1401, and the connecting rod 2 can all be disassembled. After disassembly, the tube 6 can be removed.

[0044] The working principle of this device is as follows: When wastewater needs to be treated, the wastewater is injected into the filter box 1. The wastewater entering the filter box 1 enters through the water inlet 7 on the outside of the pipe body 6. These water inlet 7 are all located above the partition plate 12. The wastewater enters the pipe body 6 through the water inlet 7 and comes into contact with the activated carbon particles inside the pipe body 6. Then the water is discharged from the water outlet 25 at the bottom of the pipe body 6. During the contact process, due to the porous characteristics of the activated carbon surface, suspended solids and other impurities are adsorbed. When a filter membrane is used to filter suspended solids, it will cause the filter membrane to become clogged in a very short time. Therefore, activated carbon particles are used for filtration and adsorption.

[0045] After the activated carbon particles inside the tube 6 have been filtered for a period of time, the adsorption sites on their surface will decrease compared to the initial stage. At this time, the position of the tube 6 is rotated by mechanical transmission. During the rotation of the tube 6, the outer annular plate is always located inside the annular groove 8, indirectly supporting the tube 6. Initially, the positions of the first conveying hole 4 and the second conveying hole 5 at the bottom of the container 3 do not coincide, and the positions of the lower exchange hole 10 and the discharge hole 11 also do not coincide. However, after the tube 6 rotates a certain angle, the positions of the first conveying hole 4 and the second conveying hole 5 coincide, and the positions of the exchange hole 10 and the discharge hole 11 also coincide. At this time, the activated carbon particles in the container 3 will pass through the first conveying hole 4 and the second conveying hole 5. The conveying hole 5 enters the interior of the tube body 6, and the activated carbon particles located at the lower end of the tube body 6 pass through the exchange hole 10 and enter the discharge hole 11. This replenishes the interior of the tube body 6 with unused activated carbon particles and discharges the activated carbon particles at the bottom. The discharge hole 11 is set at an angle downwards, and the size of the end gradually increases, so that the activated carbon particles in the discharge hole 11 will not clog. Secondly, during this process, a small amount of water will enter the discharge hole 11 along with the activated carbon particles. The drain hole 13 located in the discharge hole 11 then plays its role, draining some of the water back into the filter box 1 below the partition 12. The overlap time between the first conveying hole 4 and the second conveying hole 5 is controlled according to the number of activated carbon particles that need to be added.

[0046] A top cover is provided on the top of the container 3 for adding material. At the same time, the round shaft 26 at the lower end of the container 3 extends into the interior of the tube 6, and a spiral impeller 28 is provided on the outside of the round shaft 26. The impeller 28 has a reserved hole to facilitate the smooth flow of water. When the tube 6 rotates, there will be relative rotation between it and the impeller 28. During the contact process, it is beneficial to discharge the material at the bottom. Due to the water flowing from top to bottom for a period of time, the activated carbon particles will be in closer contact. With the relative rotation between the impeller 28 and the tube 6, the gap between the activated carbon particles can be readjusted, which can solve the problem of the water flow rate decreasing due to the smaller gap between the activated carbon particles. Secondly, the protrusions 27 on the impeller 28 help to turn the activated carbon particles during the contact process, further adjusting the gap between the particles.

[0047] During the addition and discharge of activated carbon particles, the tube 6 rotates. The activated carbon particles inside, through contact and friction with the impeller 28, tear apart some cyanobacteria. The resulting cyanobacteria particles are washed down with the water flow. Therefore, an adjustable bracket 17 is installed below the tube 6. The bracket 17 is annular, and a filter bucket 15 is placed inside it. The upper edge of the filter bucket 15 extends horizontally outward, allowing it to fit perfectly within the bracket 17. The center of the filter bucket 15 is concave, and a microfiltration membrane is laminated to its surface. These microfiltration membranes allow water to pass through quickly while simultaneously trapping small cyanobacteria particles. Because the suspended matter has been adsorbed by the activated carbon, the suspended... The problem of the material not clogging the microfiltration membrane in a short time is addressed. Secondly, through the cooperation between the first transmission gear 18, the chain 19, and the second transmission gear 20, the synchronous movement of the circular tube 6 and multiple filter hoppers 15 is achieved. One cycle is defined as one feeding and unloading operation into the tube 6, that is, from the point where the first conveying hole 4 and the second conveying hole 5 coincide to the next point where they coincide. During this cycle, the filter hopper 15 below the tube 6 moves away, and the adjacent filter hopper 15 appears below the tube 6 and stops moving. Since there is an interval in the feeding process, the tube 6 and the motor 22 also operate intermittently. Therefore, the filter hopper 15 will stay below the tube 6 for a period of time to collect the broken blue-green algae particles.

[0048] A square hole 23 is provided on the outer wall at the lower end of the filter box 1. When the filter hopper 15 rotates, each filter hopper 15 will pass through the square hole 23 and appear outside the filter box 1 at a certain moment. At this time, the operator can observe the situation inside the filter hopper 15 to consider whether to replace it, and the replacement can be carried out without stopping the machine.

[0049] On both sides of the tube body 6, there are pin assemblies 14 consisting of a bracket 1401, a limiting plate 1402, a pin rod 1403, and a through hole 1404. When there is no filter funnel 15 below the pin rod 1403, it will hang down naturally, and the limiting plate 1402 will fit against the inner side of the bracket 1401. When the filter funnel 15 gradually moves towards the lower end of the tube body 6, the bottom of the pin rod 1403 contacts the upper end of the filter funnel 15. Since the bottom of the pin rod 1403 is spherical, the pin rod 1403 will move from the upper side of the filter funnel 15 to the upper end of the funnel 15. Until the filter bucket 15 stops moving, the bottom of the pin rod 1403 is inserted into the positioning hole 16 provided at the upper end of the filter bucket 15. This is because the filter bucket 15 vibrates laterally during contact with the water flow. This setting can limit the lateral vibration of the filter bucket 15. The inner side of the positioning hole 16 is also hemispherical. When the filter bucket 15 continues to move, the ball at the bottom of the pin rod 1403 can smoothly come out of the positioning hole 16. The bracket 1401 is horizontally placed in a U-shape and will not come into contact with the moving chain 19.

[0050] The first transmission gear 18, the bracket 1401, and the connecting rod 2 can all be disassembled. After disassembly, the tube 6 can be removed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
