[0002] With the development of urbanization, water pollution and shortage problems are becoming more and more serious. Drinking water treatment has become an indispensable part in modern society.

[0003] The treatment of drinking water is a complex process, which mainly includes several steps such as raw water extraction, coagulation, sedimentation, filtration, and disinfection. Sedimentation is to let the coagulated water flow into the sedimentation tank, and rely on gravity to make large particles of impurities settle to the bottom. However, there are still some residues suspended on the surface of the water after sedimentation. These residues cannot be precipitated, including algae, bacteria, viruses and high-molecular organic matter. Filtration is to remove these residues that cannot be precipitated to make the water clear.

[0004] Currently, skimmers are used to remove these residues by rotating. However, the treated water flows out from the surrounding areas of the water treatment pool. When the skimmer rotates, the residues are often skimmed out of the pool and mixed with the water flowing out from the surrounding areas, resulting in incomplete filtration of the residues.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figure 1-Figure 8A drinking water filtering structure includes a fixing frame 1 and a collecting box 3. A water outlet box 2 is installed on the fixing frame 1. The water outlet box 2 and the collecting box 3 are respectively used to be arranged on the inner side and the outer side of the water treatment pool 6. Water enters from the upper end of the water outlet box 2 and is discharged from the bottom; the filtering structure also includes a filter residue mechanism 4. The filter residue mechanism 4 includes a mounting frame 41 and a flexible filter residue member 40. A folding component 42 is arranged below the mounting frame 41. The folding component 42 includes a lifting plate 421. The lifting plate 421 is circumferentially hinged with a plurality of connecting rods 1 422. Each connecting rod 1 422 is correspondingly provided with a connecting rod 2 423. The bottom of the mounting frame 41 is rotatably connected with a circular ring. The two ends of the connecting rod 2 423 are respectively connected to the connecting rod 1 422 and the circular ring. The ring is hinged, and the flexible filter residue member 40 is fixedly connected to the lower surface of a plurality of connecting rods 422; the filtering structure also includes a transfer mechanism 5, which is used to transfer the flexible filter residue member 40 between the water outlet box 2 and the collection box 3; the filter residue mechanism 4 also includes a lifting component 43 and a rotating component 44, the lifting component 43 is used to drive the lifting plate 421 to move vertically, so that the flexible filter residue member 40 is folded, and when the flexible filter residue member 40 is unfolded, the water surface residue in the water outlet box 2 floats on the surface of the flexible filter residue member 40, and the rotating component 44 is used to drive the lifting plate 421 to rotate, so that the flexible filter residue member 40 rotates, and when the flexible filter residue member 40 rotates, the residue on the surface of the flexible filter residue member 40 is thrown into the collection box 3.

[0030] In the above technical scheme, the flexible filter residue member 40 is unfolded in the water outlet box 2, so that the residue in the water floats above the flexible filter residue member 40. When the transfer mechanism 5 transfers the flexible filter residue member 40 from the water outlet box 2 to the collecting box 3, the flexible filter residue member 40 can filter out the residue and bring it to the collecting box 3. When in the collecting box 3, the flexible filter residue member 40 is folded and then rotated centrifugally, so that the residue on the surface of the flexible filter residue member 40 can be thrown into the inside of the collecting box 3. This process can be repeated to achieve the filtration of residue in the water.

[0031] In this embodiment, if Figure 2 and Figure 3 As shown, the lifting assembly 43 includes a fixed seat 431 and a linear drive component 433, and the fixed seat 431 and the linear drive component 433 are fixedly installed on the upper surface of the mounting frame 41. A main shaft 432 is vertically movably inserted on the fixed seat 431, and the bottom of the main shaft 432 is fixedly connected to the lifting plate 421. The output end of the linear drive component 433 is fixedly connected to a connecting plate 434, and the upper end of the main shaft 432 is rotatably connected to the connecting plate 434.

[0032] It should be noted that the linear drive component 433 can drive the main shaft 432 to move vertically through the connecting plate 434. Figure 2 and Figure 3As shown, the flexible filter residue member 40 is in an unfolded state. When the main shaft 432 drives the lifting plate 421 to move upward, the connecting rod 1 422 rotates downward, so that the flexible filter residue member 40 can be folded and folded. When the main shaft 432 drives the lifting plate 421 to move downward, the connecting rod 1 422 rotates upward, so that the flexible filter residue member 40 can be unfolded. Among them, the linear drive component 1 433 is a cylinder.

[0033] Furthermore, if Figure 2 and Figure 3 As shown, the rotating assembly 44 includes a rotating driving component 441, which is fixedly mounted on the mounting frame 41, a pulley 442 is fixedly mounted on the output end of the rotating driving component 441, a pulley 443 is rotatably connected to the upper end of the fixed seat 431, a main shaft 432 is vertically movably inserted in the middle of the pulley 443, and the pulley 442 and the pulley 443 are connected through a belt 444.

[0034] It should be noted that the main shaft 432 and the second pulley 443 can be connected by a spline connection, so that the main shaft 432 can move vertically relative to the second pulley 443, and the rotating drive component 1 441 can drive the main shaft 432 to rotate through the first pulley 442, the belt 444 and the second pulley 443. When the main shaft 432 rotates, it can drive the lifting plate 421, the connecting rod 1 422, the second connecting rod 423 and the ring connected to the second connecting rod 423 to rotate, thereby achieving the purpose of throwing away the residue on the surface of the flexible filter residue member 40, wherein the rotating drive component 1 441 is a motor.

[0035] In this embodiment, if Figure 1 and Figure 4-Figure 7 As shown, the transfer mechanism 5 includes a fixed plate 51, on which a fixed cylinder 52 is vertically fixedly installed, a movable sleeve 53 is provided on the outer movable sleeve 52, a mounting plate 531 is fixedly installed on one side of the movable sleeve 53, and the mounting plate 531 is fixedly connected to the mounting frame 41. The transfer mechanism 5 also includes a power assembly 54, which is used to drive the movable sleeve 53 to move or rotate vertically.

[0036] Furthermore, the power assembly 54 includes a screw rod 541, which is rotatably connected to the inside of the fixed cylinder 52. A rotation drive component 542 is installed on the fixed plate 51. The output end of the rotation drive component 542 is connected to the screw rod 541. A nut 543 threadedly connected to the screw rod 541 is provided inside the fixed cylinder 52. A guide shaft 544 is connected to one side of the nut 543. The guide shaft 544 extends to the outside of the fixed cylinder 52 and is fixedly connected to the movable sleeve 53.

[0037] Furthermore, a guide groove 520 is opened on the outer side of the fixed cylinder 52, and the guide groove 520 includes a vertical groove 521 and a horizontal groove 522. One end of the horizontal groove 522 is connected to the upper end of the vertical groove 521, and the guide shaft 544 slides inside the guide groove 520.

[0038] It should be noted that if Figure 4 As shown, the movable sleeve 53 is at the bottom position, when the second rotating driving component 542 drives the screw rod 541 clockwise ( Figure 4-Figure 6 When the guide shaft 544 moves from the bottom of the vertical slot 1 521 to the upper end of the vertical slot 1 521, the limit of the vertical slot 1 521 becomes invalid due to the existence of the transverse slot 522. Therefore, the guide shaft 544 enters the transverse slot 522 and slides inside the transverse slot 522. At this time, the movable sleeve 53 and the mounting plate 531 rotate clockwise, and the rotation angle can be set according to the position of the collection box 3. Similarly, when the rotating drive component 2 542 drives the screw rod 541 to rotate counterclockwise ( Figure 4-Figure 6 When the guide shaft 544 rotates in the horizontal groove 522 toward the direction of the vertical groove 1 521, the movable sleeve 53 and the mounting plate 531 rotate counterclockwise. When the guide shaft 544 moves into the vertical groove 1 521, the guide shaft 544 cannot move in the horizontal direction due to the limitation of the side wall of the vertical groove 1 521. Therefore, the guide shaft 544 can only move downward along the vertical groove 1 521. At this time, the movable sleeve 53 and the mounting plate 531 move downward. In other words, when the screw rod 541 rotates clockwise, the movable sleeve 53 and the mounting plate 531 first move upward and then rotate clockwise. When the screw rod 541 rotates counterclockwise, the movable sleeve 53 and the mounting plate 531 first rotate counterclockwise and then move downward. Among them, the rotation drive component 2 542 is a motor.

[0039] In this embodiment, the implementation method is as follows: during installation, the fixing frame 1 is installed on the side wall of the water treatment tank 6, the fixing plate 51 is installed on the outer side wall of the water treatment tank 6, and then the collection box 3 is placed at a suitable position outside the water treatment tank 6, such as Figure 8 As shown. The water level in the water treatment pool 6 is slightly higher than the upper end of the water outlet box 2, so that the water in the water treatment pool 6 can enter the inside of the water outlet box 2 along the inner wall of the water outlet box 2. The bottom of the water outlet box 2 is provided with a water outlet pipe, and the outlet of the water outlet pipe is located outside the water treatment pool 6. The water entering the water outlet box 2 flows out from the water outlet pipe. The drainage speed is controlled to keep the water level in the water outlet box 2 basically constant. In addition, the water level in the water outlet box 2 is lower than the water level in the water treatment pool 6.

[0040] The initial state is Figure 1 As shown, the flexible filter residue component 40 is located on the inner side of the water outlet box 2, and the movable sleeve 53 and the mounting plate 531 are at the lowest position, that is, the flexible filter residue component 40 is at the lowest position. At this time, the water in the water treatment tank 6 enters the interior of the water outlet box 2 along the inner wall of the water outlet box 2 and is discharged from the water outlet pipe. The water level in the water outlet box 2 is higher than the upper surface of the flexible filter residue component 40, and the residue of the water flowing into the flexible filter residue component 40 floats above the flexible filter residue component 40.

[0041] First, the rotating driving component 542 drives the screw rod 541 to rotate clockwise to drive the movable sleeve 53 and the mounting plate 531 to move upward, and the mounting plate 531 drives the filter residue mechanism 4 to move upward, so that the flexible filter residue part 40 moves upward out of the water tank 2. During the movement, the residue on the water surface adheres to the surface of the flexible filter residue part 40 and is filtered out of the water.

[0042] Then, when the movable sleeve 53 moves to the highest point, the second rotary drive component 542 continues to drive the screw rod 541 to rotate clockwise. At this time, the movable sleeve 53 and the mounting plate 531 rotate clockwise, and the flexible filter residue component 40 rotates clockwise to the position of the collection box 3.

[0043] Secondly, the lifting assembly 43 drives the lifting plate 421 to move upward, so that the connecting rod 422 drives the flexible filter residue part 40 to fold downward, and then the rotating assembly 44 drives the folding assembly 42 and the flexible filter residue part 40 to rotate. Through the centrifugal effect, the residue attached to the upper surface of the flexible filter residue part 40 is thrown out into the inside of the collection box 3.

[0044] Finally, the lifting assembly 43 drives the lifting plate 421 to move downward to drive the filter residue mechanism 4 to unfold, and the rotating drive component 542 drives the screw rod 541 to rotate counterclockwise, and the movable sleeve 53 and the mounting plate 531 first rotate counterclockwise and then move downward, returning to the inside of the water outlet tank 2.

[0045] It should be noted that the material of the flexible filter residue member 40 is a water-permeable fabric, such as a water-permeable non-woven fabric.

[0046] It should also be noted that the diameter of the flexible filter element 40 is smaller than the inner diameter of the water outlet box 2, and the water in the water treatment tank 6 flows into the inside of the water outlet box 2 along the inner wall of the water outlet box 2. The purpose is to allow a portion of the water to flow down along the edge of the flexible filter element 40 when the flexible filter element 40 moves upward from the water outlet box 2.

[0047] The above technical scheme enables the water in the water treatment pool 6 to flow into the interior of the water outlet box 2 along the inner wall of the water outlet box 2. When the flexible filter residue part 40 is unfolded, the residue can float on the upper surface of the flexible filter residue part 40. When the flexible filter residue part 40 is transferred to the interior of the collecting box 3, the residue can be filtered out to the upper surface of the flexible filter residue part 40. The flexible filter residue part 40 is folded and collapsed, and the residue can be thrown out to the interior of the collecting box 3 for collection through centrifugal action. Compared with the prior art, the present filtering structure will not filter the residue into the water that has been discharged out of the pool, and the size does not need to be set according to the size of the water treatment pool 6. Therefore, the design, installation and maintenance are relatively convenient. It can be set up in multiple around the water treatment pool 6 as needed, and the normal use of the water treatment pool 6 will not be affected during the maintenance process.

[0048] Refer to the instruction manual Figure 4-Figure 8 When the flexible filter residue part 40 is transferred from the water outlet box 2 to the position of the collecting box 3, the filter residue mechanism 4 is folded and collapsed. Most of the flexible filter residue part 40 is located inside the collecting box 3, but a part of the upper end is located above the collecting box 3. Therefore, during centrifugation, some residue will be thrown out of the collecting box 3. To avoid this problem, specifically, the guide groove 520 also includes a vertical groove 523, the vertical groove 523 is vertically arranged, and the upper end of the vertical groove 523 is connected to the end of the transverse groove 522 away from the vertical groove 1 521, and a sealing component is provided at the upper end of the fixed cylinder 52, which is used to seal the end of the transverse groove 522 close to the vertical groove 523.

[0049] Furthermore, the blocking component includes a linear drive component 2 55 and a baffle 551 . A side slot 524 is provided on one side of the upper end of the fixed cylinder 52 . The baffle 551 is vertically movably inserted into the inside of the side slot 524 . The output end of the linear drive component 2 55 is fixedly connected to the upper end of the baffle 551 .

[0050] It should be noted that, during the clockwise rotation of the screw rod 541, the guide shaft 544 first enters the horizontal groove 522 from the vertical groove 1 521, and then enters the vertical groove 2 523 from the horizontal groove 522. At this time, the baffle 551 is driven downward by the linear drive component 2 55 to move the left end of the horizontal groove 522 ( Figure 5 The guide shaft 544 moves downward along the second vertical slot 523 due to the blocking of the baffle plate 551. That is, the movable sleeve 53, the mounting plate 531 and the filter residue mechanism 4 move upward, rotate clockwise and move downward. The downward movement process is the process of moving the flexible filter residue member 40 downward in the collection box 3. This process can make the flexible filter residue member 40 completely located inside the collection box 3, and the residue will not be thrown out to the outside during centrifugation.

[0051] When the flexible filter residue member 40 is transferred from the collection box 3 to the water outlet box 2, the baffle 551 is first used to open the horizontal groove 522, and the screw rod 541 is first rotated clockwise to move the guide shaft 544 from the bottom end of the vertical groove 2 523 to the upper end, and the screw rod 541 is then rotated counterclockwise to rotate the guide shaft 544 from the horizontal groove 522 to the vertical groove 1 521 and then from the upper end of the vertical groove 1 521 to the bottom end.

[0052] In the above technical solution, the second linear drive component 55 is a cylinder.

[0053] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
