[0002] Water contains a wide variety of substances, and its specific composition depends on the source of the wastewater, such as domestic sewage, industrial wastewater, agricultural drainage and aquaculture drainage.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1, with reference to Figure 1-2 , a water purification and filtering device, comprising a filter box 1 and a drain pipe arranged at the lower end of the filter box 1: A partition 12 is provided in the middle position of the filter box 1, and a tube body 6 is rotatably provided in the middle position of the partition 12. A water inlet hole 7 is provided at the circumferential position of the tube body 6. The bottom of the tube body 6 extends to the bottom of the partition 12, and a water outlet hole 25 is provided at the bottom thereof. A material changing structure is provided between the lower end of the tube body 6 and the partition 12. The material changing structure includes exchange holes 10 distributed in a circular array at the lower end of the tube body 6, and the same number of discharge holes 11 are provided on the inner side of the partition 12. When the tube body 6 rotates to a certain position, the exchange holes 10 and the discharge holes 11 are respectively connected to each other one by one. The discharge hole 11 is fan-shaped, and the cross-sectional size of the inner side of the discharge hole 11 gradually increases toward the position away from the exchange hole 10, and the discharge hole 11 is inclined.

[0028] A plurality of drainage holes 13 are evenly formed at the bottom of the discharge hole 11 , and the lower ends of the drainage holes 13 are connected to the area below the partition 12 .

[0029] The upper end of the tube body 6 is provided with a holding box 3, and the interior of the tube body 6 and the holding box 3 are filled with activated carbon particles. The holding box 3 is fixed above the filter box 1 through the connecting rod 2. The bottom of the holding box 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 with the bottom of the holding box 3. The bottom of the holding box 3 is provided with a plurality of first delivery holes 4 in an annular shape. Figure 7 A second delivery hole 5 is provided in a ring shape at the top of the tube body 6 , and the second delivery hole 5 corresponds to the first delivery hole 4 one by one.

[0030] The interior of the containing box 3 and the upper end of the partition 12 are both concave toward the middle. A groove 8 is provided in the middle of the upper end of the partition 12. An annular plate 9 is installed on the outer side of the tube body 6 and is clamped on the inner side of 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 will enter from the water inlet holes 7 outside the tube body 6. These water inlet holes 7 are all located above the partition 12. The wastewater enters the tube body 6 from the water inlet holes 7 and will come into contact with the activated carbon particles inside the tube body 6. Then the water is discharged from the water outlet holes 25 at the bottom of the tube body 6. During the contact process, due to the porous characteristics of the activated carbon surface, suspended matter and other impurities are adsorbed. When the suspended matter is filtered with a filter membrane, the filter membrane will be blocked in a very short time. Therefore, activated carbon particles are used for filtering and adsorption.

[0032] After the activated carbon particles inside the tube body 6 have been filtered for a period of time, the adsorption sites on its surface will decrease compared to the initial stage. At this time, the position of the tube body 6 is rotated by mechanical transmission. During the rotation of the tube body 6, the annular plate on its outer side is always located on the inner side of the annular groove 8, which indirectly supports the tube body 6. At the beginning, the positions of the first conveying hole 4 and the second conveying hole 5 at the bottom of the holding box 3 do not overlap with each other, and the positions of the exchange hole 10 and the discharge hole 11 at the lower end do not overlap. However, after the tube body 6 is rotated to a certain angle, the positions of the first conveying hole 4 and the second conveying hole 5 overlap, and the positions of the exchange hole 10 and the discharge hole 11 also overlap. At this time, the activated carbon particles in the holding box 3 will pass through the first conveying hole 4 and the second conveying hole 5. The delivery hole 5 enters the interior of the tube body 6, and the activated carbon particles at the lower end of the tube body 6 will pass through the exchange hole 10 into the discharge hole 11. In this way, unused activated carbon particles are added to the interior of the tube body 6, and the activated carbon particles at the bottom are discharged. The discharge hole 11 is set to be inclined downward, and the size of the end gradually increases, which prevents the activated carbon particles from being blocked when they are in the discharge hole 11. Secondly, in this process, a small amount of water will enter the discharge hole 11 together with the activated carbon particles, and the drainage hole 13 located in the discharge hole 11 will play a role at this time, draining part of the water and returning it to the inside of the filter box 1 below the partition 12. The length of overlap between the first delivery hole 4 and the second delivery hole 5 is controlled according to the amount of activated carbon particles that need to be put in.

[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 the rotating shaft 21. A connecting seat 29 is provided above the rotating shaft 21. Several plates 24 are provided at the circumferential position of the connecting seat 29. Figure 8A bracket 17 is fixed at the end of the plate body 24, and the bracket 17 is arranged in a ring shape. A filter bucket 15 is placed on the inner side of the bracket 17, and the upper part of the filter bucket 15 is a ring-shaped plate structure. The inner wall of the filter bucket 15 is compounded with a microfiltration membrane, and multiple filter buckets 15 can be moved to the bottom of the tube body 6 in sequence.

[0034] refer to Figure 1-2 A square hole 23 is also provided on the side wall of the filter box 1. When the filter bucket 15 is in the adjustment position, it can pass through the square hole 23 in turn and move to the outside of the filter box 1.

[0035] The upper portion of the connecting seat 29 is connected to the second transmission gear 20 via a transmission shaft. The lower outer end of the tube body 6 is provided with a first transmission gear 18 . A chain 19 is sleeved between the first transmission gear 18 and the second transmission gear 20 .

[0036] During the process of adding and discharging activated carbon particles, the tube body 6 rotates, and the activated carbon particles inside it will tear up some blue algae during the process of contact and friction with the impeller 28. The formed blue algae particles are washed down with the water flow. Therefore, a bracket 17 that can adjust the position is set at the lower position of the tube body 6. The bracket 17 is arranged in a ring shape, and a filter bucket 15 is placed on the inner side of the bracket 17. The upper eaves of the filter bucket 15 are arranged to extend horizontally outward, and the filter bucket 15 can be placed in the bracket 17. The middle part of the filter bucket 15 is concave, and a microfiltration membrane is composited on its surface. These microfiltration membranes can quickly pass through precipitation while intercepting small blue algae particles. Because the suspended matter has been adsorbed by the activated carbon, the suspended matter Secondly, through the cooperation between the first transmission gear 18, the chain 19 and the second transmission gear 20, the synchronous movement of the round tube 6 and the multiple filter buckets 15 is realized, and one cycle of feeding and unloading into the tube body 6 is completed, that is, from the coincidence of the first conveying hole 4 and the second conveying hole 5 to the next coincidence. Just in this cycle, the filter bucket 15 under the tube body 6 moves back, and the adjacent filter bucket 15 appears under the tube body 6 and stops moving. Due to the interval time of feeding, the tube body 6 and the motor 22 also operate intermittently. Therefore, the filter bucket 15 will stay under the tube body 6 for a period of time to collect broken blue-green algae particles.

[0037] A square hole 23 is provided on the outer wall of the lower end of the filter box 1. When the filter buckets 15 rotate, each filter bucket 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 consider whether to replace the filter bucket 15 by observing the situation inside the filter bucket 15, and the replacement can be achieved without stopping the machine.

[0038] Example 3, reference Figure 3-4The difference between this embodiment and embodiment 1 and embodiment 2 is that a circular shaft 26 is fixed to the bottom of the containing box 3, and the circular shaft 26 extends to the interior of the tube body 6. A spiral impeller 28 is provided on the outer side of the circular shaft 26, and a plurality of protrusions 27 are also provided on the surface of the impeller 28.

[0039] An upper cover is provided on the top of the holding box 3 for adding materials. At the same time, the circular shaft 26 at the lower end of the holding box 3 extends into the interior of the tube body 6, and a spiral impeller 28 is provided on the outer side of the circular shaft 26. The impeller 28 is provided with a reserved hole to facilitate the smooth passage of water. When the tube body 6 rotates, relative rotation occurs between the impeller 28. During the contact process, it is beneficial to discharge the material at the lower end. Since the water flows from top to bottom for a period of time, the contact of the activated carbon particles will be more dense. With the help of the relative rotation between the impeller 28 and the tube body 6, the gap between the activated carbon particles can be readjusted, and the problem of the water flow rate decreasing due to the smaller gap between the activated carbon particles will be changed. Secondly, the protrusion 27 on the impeller 28 helps to turn over the activated carbon particles during the contact with the activated carbon particles, further adjusting the gap between the particles.

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

[0041] The bracket 1401 is installed at the lower end of the outer side of the tube body 6, the through hole 1404 is set at the bottom position of the bracket 1401, the limit plate 1402 is fixed at the top position of the latch rod 1403, the latch rod 1403 slides in the through hole 1404, and a positioning hole 16 is set at the upper end of the filter bucket 15. When the filter bucket 15 is transferred to the bottom of the tube body 6, the bottom of the latch rod 1403 extends to the inner side of the positioning hole 16, and the bottom of the latch rod 1403 is spherical.

[0042] On both sides of the tube body 6 are provided with a latch assembly 14 consisting of a bracket 1401, a limit plate 1402, a latch rod 1403, and a through hole 1404. When there is no filter funnel 15 below the latch rod 1403, it will naturally hang down, and the limit plate 1402 will fit the inner side of the bracket 1401. When the filter funnel 15 gradually moves toward the lower end of the tube body 6, the bottom of the latch rod 1403 and the upper end of the filter funnel 15 contact each other. Since the bottom of the latch rod 1403 is spherical, the latch rod 1403 will move from the upper end position of the side of the filter funnel 15 to the upper end position of the funnel 15. Until the filter bucket 15 stops moving, the bottom of the latch rod 1403 is inserted into the positioning hole 16 set at the upper end of the filter bucket 15. This is because the filter bucket 15 shakes laterally during contact with the water flow. Such a setting can have a certain limiting effect on preventing the filter bucket 15 from shaking laterally. The inner side of the positioning hole 16 is also hemispherical. When the filter bucket 15 continues to move, the spherical position at the bottom of the latch rod 1403 can come out of the positioning hole 16 smoothly. The bracket 1401 is a horizontally placed U-shaped setting, and there will be no contact problem 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 body 6 can be removed.

[0044] The working principle of the device is: When wastewater needs to be treated, the wastewater is injected into the filter box 1. The wastewater entering the filter box 1 will enter from the water inlet holes 7 outside the tube body 6. These water inlet holes 7 are all located above the partition 12. The wastewater enters the tube body 6 from the water inlet holes 7 and will come into contact with the activated carbon particles inside the tube body 6. Then the water is discharged from the water outlet holes 25 at the bottom of the tube body 6. During the contact process, due to the porous characteristics of the activated carbon surface, suspended matter and other impurities are adsorbed. When the suspended matter is filtered with a filter membrane, the filter membrane will be blocked in a very short time. Therefore, activated carbon particles are used for filtering and adsorption.

[0045] After the activated carbon particles inside the tube body 6 have been filtered for a period of time, the adsorption sites on its surface will decrease compared to the initial stage. At this time, the position of the tube body 6 is rotated by mechanical transmission. During the rotation of the tube body 6, the annular plate on its outer side is always located on the inner side of the annular groove 8, which indirectly supports the tube body 6. At the beginning, the positions of the first conveying hole 4 and the second conveying hole 5 at the bottom of the holding box 3 do not overlap with each other, and the positions of the exchange hole 10 and the discharge hole 11 at the lower end do not overlap. However, after the tube body 6 is rotated to a certain angle, the positions of the first conveying hole 4 and the second conveying hole 5 overlap, and the positions of the exchange hole 10 and the discharge hole 11 also overlap. At this time, the activated carbon particles in the holding box 3 will pass through the first conveying hole 4 and the second conveying hole 5. The delivery hole 5 enters the interior of the tube body 6, and the activated carbon particles at the lower end of the tube body 6 will pass through the exchange hole 10 into the discharge hole 11. In this way, unused activated carbon particles are added to the interior of the tube body 6, and the activated carbon particles at the bottom are discharged. The discharge hole 11 is set to be inclined downward, and the size of the end gradually increases, which prevents the activated carbon particles from being blocked when they are in the discharge hole 11. Secondly, in this process, a small amount of water will enter the discharge hole 11 together with the activated carbon particles, and the drainage hole 13 located in the discharge hole 11 will play a role at this time, draining part of the water and returning it to the inside of the filter box 1 below the partition 12. The length of overlap between the first delivery hole 4 and the second delivery hole 5 is controlled according to the amount of activated carbon particles that need to be put in.

[0046] An upper cover is provided on the top of the holding box 3 for adding materials. At the same time, the circular shaft 26 at the lower end of the holding box 3 extends into the interior of the tube body 6, and a spiral impeller 28 is provided on the outer side of the circular shaft 26. The impeller 28 is provided with a reserved hole to facilitate the smooth passage of water. When the tube body 6 rotates, relative rotation occurs between the impeller 28. During the contact process, it is beneficial to discharge the material at the lower end. Since the water flows from top to bottom for a period of time, the contact of the activated carbon particles will be more dense. With the help of the relative rotation between the impeller 28 and the tube body 6, the gap between the activated carbon particles can be readjusted, and the problem of the water flow rate decreasing due to the smaller gap between the activated carbon particles will be changed. Secondly, the protrusion 27 on the impeller 28 helps to turn over the activated carbon particles during the contact with the activated carbon particles, further adjusting the gap between the particles.

[0047] During the process of adding and discharging activated carbon particles, the tube body 6 rotates, and the activated carbon particles inside it will tear up some blue algae during the process of contact and friction with the impeller 28. The formed blue algae particles are washed down with the water flow. Therefore, a bracket 17 that can adjust the position is set at the lower position of the tube body 6. The bracket 17 is arranged in a ring shape, and a filter bucket 15 is placed on the inner side of the bracket 17. The upper eaves of the filter bucket 15 are arranged to extend horizontally outward, and the filter bucket 15 can be placed in the bracket 17. The middle part of the filter bucket 15 is concave, and a microfiltration membrane is composited on its surface. These microfiltration membranes can quickly pass through precipitation while intercepting small blue algae particles. Because the suspended matter has been adsorbed by the activated carbon, the suspended matter Secondly, through the cooperation between the first transmission gear 18, the chain 19 and the second transmission gear 20, the synchronous movement of the round tube 6 and the multiple filter buckets 15 is realized, and one cycle of feeding and unloading into the tube body 6 is completed, that is, from the coincidence of the first conveying hole 4 and the second conveying hole 5 to the next coincidence. Just in this cycle, the filter bucket 15 under the tube body 6 moves back, and the adjacent filter bucket 15 appears under the tube body 6 and stops moving. Due to the interval time of feeding, the tube body 6 and the motor 22 also operate intermittently. Therefore, the filter bucket 15 will stay under the tube body 6 for a period of time to collect broken blue-green algae particles.

[0048] A square hole 23 is provided on the outer wall of the lower end of the filter box 1. When the filter buckets 15 rotate, each filter bucket 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 consider whether to replace the filter bucket 15 by observing the situation inside the filter bucket 15, and the replacement can be achieved without stopping the machine.

[0049] On both sides of the tube body 6 are provided with a latch assembly 14 consisting of a bracket 1401, a limit plate 1402, a latch rod 1403, and a through hole 1404. When there is no filter funnel 15 below the latch rod 1403, it will naturally hang down, and the limit plate 1402 will fit the inner side of the bracket 1401. When the filter funnel 15 gradually moves toward the lower end of the tube body 6, the bottom of the latch rod 1403 and the upper end of the filter funnel 15 contact each other. Since the bottom of the latch rod 1403 is spherical, the latch rod 1403 will move from the upper end position of the side of the filter funnel 15 to the upper end position of the funnel 15. Until the filter bucket 15 stops moving, the bottom of the latch rod 1403 is inserted into the positioning hole 16 set at the upper end of the filter bucket 15. This is because the filter bucket 15 shakes laterally during contact with the water flow. Such a setting can have a certain limiting effect on preventing the filter bucket 15 from shaking laterally. The inner side of the positioning hole 16 is also hemispherical. When the filter bucket 15 continues to move, the spherical position at the bottom of the latch rod 1403 can come out of the positioning hole 16 smoothly. The bracket 1401 is a horizontally placed U-shaped setting, and there will be no contact problem 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 body 6 can be removed.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
