Description

Technical Field

[0001] The invention relates to the technical field of tap water pipe networks, and in particular to a tap water pipe network filtering device. Background Art

[0002] The tap water network is an important part of the urban water supply system. It is responsible for transporting treated clean water from the water plant to every corner of the city to meet the water needs of residents, industrial production, public services and other aspects. The tap water network mainly includes water sources, water treatment plants, water pipelines, booster pumping stations and user terminals. Among them, the water pipelines include main pipes, branch pipes and supporting pipes.

[0003] Filtration in the tap water network is one of the important steps to ensure water safety. The filtration process is usually carried out in a water treatment plant, but secondary filtration can also be carried out at certain key nodes in the network to ensure continuous cleanliness of the water quality, such as filtration in branch pipes or household pipes to ensure water safety.

[0004] At present, when performing the above-mentioned secondary filtration, a pipeline filter, a pre-filter or an activated carbon filter is usually connected to the pipeline to further filter out impurities in the transportation process and further ensure the safety of water use.

[0005] The above filtering process has the following problems: 1. Since the inside of the pipeline is sealed and the water flow pressure is strong, when the filtering effect of the above filter decreases after long-term use, the pipeline needs to be closed first, and then the filter needs to be taken out for replacement. During this process, the pipeline is in a closed state and the water supply is stopped, affecting normal water use. Secondly, the current filters are usually disposable devices or integrated devices. The cost of direct replacement is high, and it is difficult to ensure the cleaning effect by external cleaning, which leads to a lower filtering capacity of the filter and affects water safety.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 , Figure 2 and Figure 8 As shown, a tap water pipe network filtering device comprises: two Y-shaped tubes 1, the two Y-shaped tubes 1 are staggered up and down and the Y-shaped structures of the two are symmetrical front to back, a mounting cylinder 2 with an upper end opening is commonly provided at the intersection of the two Y-shaped tubes 1, a blocking cylinder 3 connected with the corresponding Y-shaped tube 1 is fixedly provided on the two branch pipes of the Y-shaped tube 1, a blocking unit 4 is provided in the blocking cylinder 3, the blocking unit 4 comprises a blocking piece 40 for blocking the branch pipes of the Y-shaped tube 1, a T-shaped frame 5 is provided between the two Y-shaped tubes 1, and sliding rods 50 are movably provided at both ends of the horizontal section of the T-shaped frame 5.

[0035] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, a filter mechanism 6 is arranged in the mounting cylinder 2, and the filter mechanism 6 includes a mounting plate 60. The mounting plate 60 is fixedly arranged on the lower end surface of the sliding rod 1 50, and a filter element 1 600, a filter element 2 601 and a filter mesh plate 603 are arranged in sequence from top to bottom below the mounting plate 60. The lower ends of the filter element 1 600, the filter element 2 601 and the filter mesh plate 603 are all open and arranged in sequence from outside to inside. The insides of the filter element 1 600 and the filter element 2 601 are filled with substances for filtering water (such as activated carbon, quartz sand, pp cotton, etc.), an annular plate 604 is arranged below the filter element 1 600, and a locking unit 61 is arranged on the annular plate 604, and a cleaning unit 62 for self-cleaning the filter element 1 600, the filter element 2 601 and the filter mesh plate 603 is arranged on the mounting plate 60.

[0036] like Figure 1 , Figure 2 and Figure 8 As shown, the left and right sides of the T-shaped frame 5 are provided with a switching unit 7 for switching the upper and lower positions of the blocking unit 4 and the mounting plate 60 .

[0037] It should be noted that the front Y-shaped tube 1 in the device is the water inlet pipe and the rear Y-shaped tube 1 is the water outlet pipe, and the operation processes of the two together constitute three operation states. The first state is that the two branch pipes of the Y-shaped tube 1 are in the filtering operation state, the second state is that the left branch pipe of the Y-shaped tube 1 is in the filtering operation state, and the right branch pipe is in a closed state, and in this state the filter mechanism 6 in the right installation tube 2 is cleaned; the third state is that the right branch pipe of the Y-shaped tube 1 is in the filtering operation state, and the left branch pipe is in a closed state, and in this state the filter mechanism 6 in the left installation tube 2 is cleaned.

[0038] The initial state is the first state, and the filter mechanisms 6 in the two installation cylinders 2 are both in the filtering operation state. When one of the filter mechanisms 6 needs to be cleaned or the internal filtering material is replaced, the switching unit 7 operates to make the two blocking units 4 corresponding to the filter mechanism 6 operate, and the blocking member 40 moves down to block the branch pipe of the corresponding Y-shaped tube 1. Therefore, the pressure in the installation cylinder 2 is reduced at this time. After that, as the switching unit 7 continues to operate, the installation plate 60 in the filter mechanism 6 drives the filter element 1 600, the filter element 2 601 and the filter screen plate 603 thereon. Remove the installation cylinder 2, unlock the locking unit 61 to separate the three, manually take out and replace the substances inside for filtering water, and clean the three at the same time to ensure the filtering effect of the three. After completing the above operations, lock the filter element 1 600, the filter element 2 601 and the filter screen plate 603 through the locking unit 61, and then the switching unit 7 works to make the filter mechanism 6 return to the installation cylinder 2 and lock it. Finally, the above-mentioned two blocking members 40 move up to release the blockage of the branch pipe of the Y-shaped tube 1, so that the filter mechanism 6 can be put into the filtering operation again.

[0039] The above process ensures that the tap water network is always in a flowing state, avoiding the problem of water supply being stopped while cleaning the interior. Secondly, by removing the filter mechanism 6 for cleaning, the filtering capacity of the filter mechanism 6 is guaranteed, ensuring the filtering effect on the tap water.

[0040] like Figure 1 , Figure 2 and Figure 8 As shown, the blocking unit 4 also includes a moving rod 41. The upper end surface of the blocking cylinder 3 slides up and down and is penetrated by a moving rod 41 with a vertical axis. The blocking member 40 is fixedly arranged on the corresponding lower end surface of the moving rod 41. The blocking member 40 is a cylindrical section and a hemispherical section from top to bottom.

[0041] The switching unit 7 works so that the moving rod 41 drives the blocking piece 40 to move in the up and down directions. The two blocking pieces 40 on the same Y-shaped tube 1 have three operating states: both blocking pieces 40 are not blocked, the left blocking piece 40 is not blocked and the right blocking piece 40 is blocked, and the left blocking piece 40 is blocked and the right blocking piece 40 is not blocked.

[0042] like Figure 5 , Figure 6 and Figure 7 As shown, the locking unit 61 includes a rectangular groove 610, and two front-to-back symmetrical rectangular grooves 610 are provided on the annular plate 604. A groove group corresponding to the rectangular grooves 610 is provided on the upper end surface of the annular plate 604, and the groove group includes three connecting grooves 611 distributed front to back and connected to the rectangular grooves 610. The lower end surfaces of the filter element 1 600, the filter element 2 601 and the filter screen plate 603 are fixedly provided with a circular block 612 corresponding to the connecting groove 611, and an L-shaped locking strip 613 is slidably provided on the inner wall of the rectangular groove 610. The vertical section of the locking strip 613 runs through the upper end of the annular plate 604, and a locking block 614 corresponding to the circular block 612 and in an L shape is fixedly provided on the locking strip 613, and a spring 1 615 is fixedly provided between the vertical section of the locking strip 613 and the inner wall of the rectangular groove 610.

[0043] like Figure 3 and Figure 5 As shown, the locking unit 61 also includes a guide ring 616. The lower end surface of the mounting plate 60 is fixedly provided with the guide ring 616, and two guide blocks 617 distributed on the left and right are fixedly provided on the guide ring 616. The inner wall of the mounting tube 2 is provided with a guide groove 618 that matches the guide block 617 one by one, and the upper end of the guide groove 618 is chamfered.

[0044] During operation, during the process of installing the filter element 1 600, the filter element 2 601 and the filter screen plate 603, the annular plate 604 is placed below the above three, and the circular blocks 612 on the above three are inserted into the corresponding rectangular grooves 610 through the connecting grooves 611. During this process, the spring 1 615 is compressed. When the circular block 612 contacts the top of the horizontal section of the locking strip 613, the elastic force generated by the deformation of the spring 1 615 causes the locking strip 613 to drive the locking blocks 614 to be inserted into the corresponding circular blocks 612. In the circular area, the fixing operation of filter element 1 600, filter element 2 601, filter screen plate 603 and annular plate 604 is completed. When releasing the fixed installation of the above three, the vertical section of the locking strip 613 is manually moved so that the two locking strips 613 on the same annular plate 604 move away from each other, and the locking block 614 withdraws from the circular area of ​​the corresponding circular block 612, and the lock is released, which is convenient for replacing the filter material in filter element 1 600 and filter element 2 601 and cleaning the flocculent impurities on the filter screen plate 603.

[0045] After the above cleaning process is completed, the switching unit 7 drives the sliding rod 50 to drive the corresponding mounting plate 60 to move downward, and the guide block 617 on the guide ring 616 cooperates with the corresponding guide groove 618 to guide the downward movement of the mounting plate 60, the filter element 1 600, the filter element 2 601 and the filter mesh plate 603 to ensure that the lower ends of the filter element 1 600, the filter element 2 601 and the filter mesh plate 603 are close to the lower inner wall of the mounting tube 2.

[0046] like Figure 4 , Figure 5 and Figure 6 As shown, the cleaning unit 62 includes a rotating shaft 620, a rotating shaft 620 with a vertical axis is installed on and through the filter plate 603, a rotating shaft 621 is installed on and through the filter element 601, a rotating shaft 3 622 is installed on and through the filter element 1 600, and the rotating shaft 3 622 is rotatably set on the mounting plate 60. The axes of the rotating shaft 1 620, the rotating shaft 2 621 and the rotating shaft 3 622 are colinear, and L-shaped cleaning strips 623 are fixedly set on the rotating shaft 1 620, the rotating shaft 2 621 and the rotating shaft 3 622.

[0047] like Figure 4 , Figure 5 and Figure 6 As shown, the cleaning unit 62 also includes a driving blade 624, and a plurality of circumferentially evenly distributed driving blades 624 are fixedly provided at the lower end of the rotating shaft 1 620, a driving sleeve 625 is fixedly provided on the lower end surfaces of the rotating shaft 2 621 and the rotating shaft 3 622, a driving strip 626 is fixedly provided on the upper ends of the rotating shaft 1 620 and the rotating shaft 2 621, and a slot 627 cooperating with the driving strip 626 is provided on the lower end surface of the driving sleeve 625.

[0048] During operation, when the filter mechanism 6 in the installation tube 2 performs filtering operations, water flows from the branch pipe of the front Y-shaped tube 1 into the bottom of the installation tube 2, and the impact force brought by the water flow causes the driving blade 624 to rotate, and the driving blade 624 drives the rotating shaft 1 620, the rotating shaft 2 621 and the rotating shaft 3 622 to rotate synchronously, and all the cleaning strips 623 rotate synchronously to perform internal self-cleaning operations, thereby ensuring the filtering performance of the filter element 1 600, the filter element 2 601 and the filter screen plate 603, and avoiding the problem that the above three are blocked and affect the flow of water.

[0049] Secondly, during the installation process, by snapping the drive bar 626 into the corresponding drive sleeve 625, the rotating shaft 1 620, the rotating shaft 2 621 and the rotating shaft 3 622 can be quickly assembled and the axes of the three can be kept in line, ensuring that the lower ends of the filter element 1 600, the filter element 2 601 and the filter screen plate 603 can be accurately assembled, while facilitating the synchronous rotation of all the cleaning bars 623. The above-mentioned detachable assembly method facilitates cleaning and maintenance operations after disassembly, thereby improving the overall convenience of the device.

[0050] like Figure 1 and Figure 8 As shown, the switching unit 7 includes a synchronization plate 70, and the front and rear end surfaces of the T-shaped frame 5 are both rotatably provided with a synchronization plate 70 corresponding to the two Y-shaped tubes 1 through a connecting rod extending from front to rear through an axis. The synchronization plate 70 is slidably provided with two connecting columns along its length direction toward the end surface of the corresponding Y-shaped tube 1, and a synchronization bar 701 is fixedly provided on the connecting column, and the moving rod 41 is fixedly connected to the synchronization bar 701.

[0051] During operation, when switching the operating state, the two moving rods 41 on the same Y-shaped tube 1 are controlled by the corresponding two connecting columns on the synchronization plate 70 to drive the corresponding blocking parts 40 to move up and down, and the two blocking parts 40 on the same Y-shaped tube 1 have three states. The first state is that the left blocking part 40 is at the highest point and the right blocking part 40 is at the lowest point, realizing the left-open and right-closed state. The second state is that the two blocking parts 40 are both in the middle position, realizing the left and right opening. The third state is that the left blocking part 40 is at the lowest point and the right blocking part 40 is at the highest point, realizing the left-closed and right-open state.

[0052] like Figure 1 , Figure 8 and Fig. 9 As shown, the switching unit 7 also includes a vertical frame 71, and the vertical frames 71 are arranged on both sides of the left and right sides of the vertical section of the T-shaped frame 5. A swing plate 710 is rotatably arranged on the vertical frame 71, and two waist-shaped grooves 711 distributed on the left and right are provided on the swing plate 710. A sliding block 712 is slidably arranged in the waist-shaped groove 711, and a horizontal column extending from the front to the back through the axis is rotatably passed through the sliding block 712. A driving block 714 is fixedly arranged on the horizontal column close to the T-shaped frame 5, and the center of gravity of the driving block 714 is located below the center position, so that the driving block 714 always maintains the same state (i.e. Fig. 9In the state shown, a driving block 2 715 is fixedly provided on the horizontal column away from the T-shaped frame 5 (the driving block 2 715 is driven by an external hydraulic cylinder to move up and down), the driving block 2 715 is slidably sleeved on the corresponding sliding rod 1 50, and a spring 2 716 sleeved on the sliding rod 1 50 is fixedly provided between the driving block 2 715 and the mounting plate 60. Two sliding rods 2 717 that slide up and down and are symmetrical on the left and right are installed through the T-shaped frame 5, and a horizontal bar 718 is fixedly provided on the lower end surface of the sliding rod 2 717. The horizontal bar 718 is fixedly connected to the two corresponding moving rods 41 below, and the left and right end surfaces of the vertical section of the T-shaped frame 5 are fixedly provided with matching blocks 1 719. The end surface of the matching block 1 719 facing the adjacent mounting cylinder 2 and the front end surface of the driving block 1 714 are provided with a clamping groove 1 720, and a clamping bar 1 721 that matches the clamping groove 1 720 is fixedly provided on the sliding rod 2 717.

[0053] like Figure 1 , Figure 8 and Fig. 9 As shown, a second locking strip 722 is fixedly sleeved on the sliding rod 1 50, a second matching block 723 corresponding to the second locking strip 722 is fixedly provided on the vertical frame 71, and a second locking groove 724 is provided on the matching block 723. The switching unit 7 also includes a rotating handle 725, and the upper ends of the sliding rod 1 50 and the sliding rod 2 717 are both fixedly provided with a rotating handle 725.

[0054] The initial working state of the device is the first working state, at this time, the locking strip 721 is locked into the locking groove 720 on the corresponding matching block 719, and the locking strip 722 is locked into the locking groove 724 on the corresponding matching block 723, and the right filter mechanism 6 needs to be cleaned at this time. At the same time, in this state, the blocking parts 40 are all in the middle position, and the Y-shaped tube 1 is all in the open state. At this time, the rotating handle 725 is manually rotated to make the sliding rod 717 drive the locking strip 721 thereon to rotate and withdraw from the locking groove 720 on the corresponding matching block 719. Therefore, all the blocking parts 40 are in the unlocked state at this time, but the left filter mechanism 6 is still in the locked state through the cooperation between the corresponding locking strip 722 and the corresponding locking groove 724.

[0055] After that, the external hydraulic cylinder works to drive the right driving block 2 715 to move up, the spring 2 716 is stretched, and the driving block 2 715 drives the right driving block 1 714 to move down through the corresponding swing plate 710, and the driving block 1 714 drives the sliding rod 2 717 and the two right blocking members 40 to move down synchronously, and the right side pipes of the two Y-shaped tubes 1 are blocked respectively, so the water pressure in the right filtering mechanism 6 is reduced, and then the rotating handle 725 on the right sliding rod 1 50 is manually turned to make the locking strip 2 722 move out of the locking groove 2 724, so the right filtering mechanism 6 is unlocked, and the right sliding rod 2 717 is rotated at the same time to make the right The latching strip 721 is latched into the latching groove 720 on the matching block 719 to complete the positioning and locking of the two right blocking members 40. At this time, the other latching strip 721 on the sliding rod 717 is disengaged from the latching groove 720 on the driving block 714. The driving block 714 no longer drives the sliding rod 717 to move. As the driving block 715 continues to move, the elastic force generated by the deformation of the spring 716 causes the filter mechanism 6 to move up and away from the mounting cylinder 2, so as to clean the filter mechanism 6. At this time, the right driving block 715 is located between the two latching strips 721 on the sliding rod 717. Figure 8 .

[0056] After the cleaning is completed, the right side filter mechanism 6 is reinstalled, and the external hydraulic cylinder works to drive the right side drive block 2 715 to move downward, and drive the right side filter mechanism 6 to move into the installation cylinder 2, and rotate the right side sliding rod 1 50 to make the corresponding positioning strip 2 722 rotate and move into the positioning groove 2 724, completing the locking of the right side filter mechanism 6. At this time, the right side drive block 1 714 corresponds to the positioning strip 1 721, and rotate the right side sliding rod 2 717 to make the positioning strip 1 721 move into the positioning groove 1 720 on the drive block 1 714. With the continuous operation of the external hydraulic cylinder, the drive block 2 715 drives the two right side blocking parts 40 to move upward, so that the right side branch pipeline of the Y-shaped tube 1 is opened and put into the filtering operation.

[0057] Repeat the same operation to remove, clean and replace the filter element 1 600, the filter element 2 601 and the filter screen plate 603 in the left filter mechanism 6.
