Description

Technical Field

[0001] The invention relates to the field of mineral water production, and more particularly to a filtering component in a mineral water treatment device. Background Art

[0002] Mineral water treatment and filtration components are key to ensuring the safety and hygiene of mineral water. They can remove impurities and harmful substances in the water and improve the taste of the water.

[0003] In mineral water filtration, large particles in the water, such as mud, rust and other suspended solids, are generally removed through a coarse filter, and then residual chlorine, odor, organic matter and some heavy metals in the water are removed through an activated carbon filter. Finally, dissolved salts, heavy metals, organic matter and other fine substances are removed through a filter membrane to obtain relatively pure mineral water.

[0004] In the process of coarse filtering of mineral water, since large particles in the water are easily attached to the surface of the filter, the filter needs to be cleaned frequently, which seriously reduces the filtration efficiency of the mineral water. Although the existing technology has also made improvements, such as making the filter easy to disassemble and assemble, thereby saving time wasted in cleaning the filter, the filtration device still needs to be turned off during the installation of the filter before the filter can be cleaned, which still reduces the filtration efficiency of the mineral water.

When the impurities need to be cleaned, the sealing plate needs to be moved to block the sewage trough, so that the collection box and the filter cartridge can be isolated, so that the impurities can be cleaned without stopping the filtration, thereby improving the filtration efficiency;

[0020] (2) This solution provides an elastic pad, which can drive the filter to shake during the rotation of the rotating rod, thereby loosening the impurities on the filter, making it easier for the impurities to move to the edge of the filter. At the same time, the first cleaning rod can block the impurities, and then reciprocate up and down through the cavity in the elastic pad on the filter, driving the pneumatic telescopic rod to extend back and forth. Then, during the process of the pneumatic telescopic rod extending back and forth, the cleaning block is driven to clean the impurities on the side wall of the first cleaning rod, thereby effectively preventing the impurities on the top wall of the filter from affecting the rate at which water flows through the filter, further improving the filtration efficiency.

[0021] (3) This scheme arranges an annular airbag. During the rotation of the filter, the pressure wheel is driven by the isolation plate, the spring telescopic rod and the mounting frame to squeeze the annular airbag, so that the water in the annular airbag continuously flows to the second cleaning groove, and flows to the collection box through the second cleaning groove, the filter gap and the first cleaning groove. When the water flows through the filter gap, it will drive the impurities in the filter gap to flow into the collection box through the first cleaning groove, thereby effectively preventing the filter gap from being blocked and affecting the speed of water flowing through the filter, thereby further improving the filtration efficiency.

DETAILED DESCRIPTION

[0032] 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; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 A filter assembly in a mineral water treatment device comprises: a filter cartridge 1, a first water pipe 2 for water inlet is provided on the top wall of the filter cartridge 1, and a drainage pipe 3 for drainage is inserted on the bottom wall of the filter cartridge 1;

[0034] The filter cartridge 1 further comprises a collecting assembly, wherein the collecting assembly comprises a filter screen 401 which is slidably matched with the inner wall of the filter cartridge 1, and the closer the filter screen 401 is to the edge, the smaller its vertical height is; a collecting box 402 for collecting impurities is provided on the side wall of the filter cartridge 1, a drain valve 403 connected to the outside is inserted on the bottom wall of the collecting box 402, a drain trough 404 connected to the collecting box 402 is provided on the side wall of the filter cartridge 1, a slide groove 405 connected to the drain groove 404 is provided on the filter cartridge 1, a sealing plate 406 for sealing the drain groove 404 is provided in the slide groove 405, and a driving assembly for driving the filter screen 401 to rotate is provided on the filter cartridge 1.

[0035] The driving assembly includes a rotating rod 501 rotatably mounted on the bottom wall of the filter cartridge 1, and one end of the rotating rod 501 located in the first water pipe 2 is provided with an impeller 502 for driving the rotating rod 501 to rotate. A vertical groove 503 is provided on the rotating rod 501, and a linkage block 504 is fixedly mounted on the filter screen 401 and is vertically slidably mounted with the vertical groove 503.

[0036] During use, water flows into the filter cartridge 1 through the first water pipe 2, and flows to the next process through the filter screen 401 and the drain pipe 3. In the process of water flowing through the filter cartridge 1, part of the water will flow through the sewage trough 404 to the collection box 402 and fill the entire collection box 402. At the same time, impurities in the water flow are blocked by the filter screen 401 when the water flows through the filter screen 401. Since the closer the filter screen 401 is to the edge, the smaller the vertical height is, that is, the closer the filter screen 401 is to the edge, the lower the height is, the impurities will be exerted with thrust when the water flows through the filter screen 401. Then, under the combined effect of the thrust force downward along the top wall of the filter screen 401 and the gravity of the impurities themselves, the impurities gradually approach the edge of the filter screen 401 along the top wall of the filter screen 401. At the same time, in the process of filtering the water flow, the driving component will drive the filter screen 401 to rotate. Then, in the process of the filter screen 401 rotating, the impurities on the filter screen 401 will be driven to rotate. When the filter When the impurities at the edge of the net 401 pass through the drain chute 404, the impurities will enter the collection box 402 through the drain chute 404. As the impurities in the collection box 402 accumulate, when it is necessary to clean the impurities, the user can push the sealing plate 406 upwards to make the sealing plate 406 block the drain chute 404. At this time, the user can open the drain valve 403, and then the impurities in the collection box 402 will flow to the outside through the drain valve 403 along with the water flow in the collection box 402. After the impurities in the collection box 402 flow to the outside, the user can push the sealing plate 406 downwards to make the sealing plate 406 disengage from the drain chute 404. That is, at this time, the impurities on the top wall of the filter screen 401 can flow into the collection box 402 through the drain chute 404 again. That is, through the cooperation of the sealing plate 406 and the collection box 402, the impurities in the filtration can be cleaned without stopping the filtration of the water flow, thereby improving the filtration efficiency.

[0037] In the process of water flowing into the filter cartridge 1 through the first water pipe 2, the water flow will impact the impeller 502 to drive the impeller 502 to rotate, and then drive the rotating rod 501 to rotate during the rotation of the impeller 502, and in the process of the rotation of the rotating rod 501, the rotating rod 501 drives the linkage block 504 to rotate through the vertical groove 503, and then drives the filter 401 to rotate during the rotation of the linkage block 504, and in the process of the rotation of the filter 401, the impurities on the top wall of the filter 401 can be driven to rotate, and then under the action of centrifugal force, the impurities can be accelerated to approach the edge of the filter 401, thereby further improving the efficiency of cleaning the impurities on the top wall of the filter 401, thereby effectively preventing the impurities on the top wall of the filter 401 from affecting the speed of water flowing through the filter 401, and further improving the filtration efficiency.

[0038] like Figure 2 , Figure 3 , Figure 4As shown, a first mounting ring 601 is rotatably mounted on the filter 401, and a first cleaning rod 602 for cleaning stains on the top wall of the filter 401 is rotatably mounted on the first mounting ring 601, and the bottom wall of the first cleaning rod 602 is in contact with the filter 401, and a first limiting rod 603 fixedly connected to the first cleaning rod 602 is vertically slidably mounted on the top wall of the sewage trough 404.

[0039] The rotating rod 501 is provided with a first annular groove, in which a first circular ring 604 fixedly connected to a first mounting ring 601 is slidably installed, an elastic pad 605 is fixedly installed on the top wall of the circular ring, a second circular ring 606 rotatably matched with the rotating rod 501 is fixedly installed on the top wall of the elastic pad 605, the first mounting ring 601 is provided with a groove 607 slidably matched with the second circular ring 606, an inclined block 608 is fixedly installed on the top wall of the first mounting ring 601, and the top of the limit is an inclined surface, and an impact block 609 for pushing the inclined block 608 to move downward is fixedly installed on the rotating rod 501.

[0040] A pneumatic telescopic rod 701 is fixedly mounted on the side wall of the first mounting ring 601, and a cleaning block 702 for pushing the dirt on the side wall of the first cleaning rod 602 is fixedly mounted on the output end of the pneumatic telescopic rod 701, a cavity 703 for supplying air to the pneumatic telescopic rod 701 is opened on the elastic pad 605, and a first air pipe 704 connected to the input end of the pneumatic telescopic rod 701 is inserted on the side wall of the cavity 703.

[0041] By adopting the above technical solution, since the first mounting ring 601 is vertically slidably matched with the sewage trough 404 through the first cleaning rod 602 and the first limiting rod 603, the first mounting ring 601 cannot rotate, and the impact block 609 is driven to rotate during the rotation of the rotating rod 501, and then gradually contacts the inclined surface of the inclined block 608 during the rotation of the impact block 609, and drives the inclined block 608 to move downward. During the downward movement of the inclined block 608, the filter screen 401 and the second ring 606 are driven downward through the first mounting ring 601. During the downward movement of the second ring 606, the elastic pad 605 is squeezed, and then when the impact block 609 is out of contact with the inclined block 608, the elastic pad 605 stretches and drives the first mounting ring through the second ring 606 601 is reset. Since the first mounting ring 601 and the filter screen 401 are rotatably matched, and the first mounting ring 601 and the filter screen 401 are engaged and can only rotate but cannot move relative to each other in the vertical direction, the filter screen 401 is driven to move upward during the upward resetting of the first mounting ring 601, that is, the filter screen 401 is driven to reciprocate up and down during the rotation of the rotating rod 501. During the reciprocating up and down movement of the filter screen 401, impurities on the surface of the filter screen 401 can be loosened, thereby facilitating the impurities on the top wall of the filter screen 401 to move to the edge of the filter screen 401 and enter the collection box 402, thereby further improving the cleaning efficiency of the impurities on the top wall of the filter screen 401, thereby accelerating the movement of impurities into the collection box 402, and playing a role in improving the cleaning efficiency of the impurities on the top wall of the filter screen 401.

[0042] Since the first cleaning rod 602 is always in contact with the top wall of the filter screen 401, and the filter screen 401 and the first cleaning rod 602 are slidably matched, in the process of the filter screen 401 driving the impurities to rotate, the impurities gradually come into contact with the first cleaning rod 602 and are blocked by the side wall of the first cleaning rod 602, and then gradually move into the collection box 402 under the action of the thrust component of the water flow, thereby facilitating the movement of the impurities into the collection box 402.

[0043] During the compression of the elastic pad 605, the gas in the cavity 703 is squeezed and flows to the input end of the pneumatic telescopic rod 701 through the first air pipe 704, and then the output end of the pneumatic telescopic rod 701 extends and drives the cleaning block 702 to move along the side wall of the first cleaning rod. During the movement of the cleaning block 702, impurities on the side wall of the first cleaning rod can be driven to move into the collection box 402, thereby ensuring that the impurities move into the collection box 402.

[0044] Then, when the elastic pad 605 stretches, the cavity 703 draws air from the input end of the pneumatic telescopic rod 701 through the first air pipe 704. At this time, the output end of the pneumatic telescopic rod 701 contracts and drives the cleaning block 702 to move upward along the first cleaning rod 602. Since the side wall of the cleaning block 702 close to the pneumatic telescopic rod 701 is an inclined surface, then in the process of the cleaning block 702 moving upward along the first cleaning rod 602, the impurities move along the inclined surface of the cleaning block 702 to the side of the cleaning block 702 away from the pneumatic telescopic rod 701, thereby facilitating the cleaning block 702 to clean the impurities again, thereby preparing for work again.

[0045] like Figure 2 , Figure 3 , Figure 5 As shown, an isolation plate 8 is provided on the bottom wall of the filter screen 401 for blocking the sewage trough 404 below the filter screen 401 .

[0046] A second cleaning rod 901 for cleaning the gaps in the filter 401 is provided on the bottom wall of the filter 401, a second annular groove rotatably matched with the second cleaning rod 901 is provided on the top wall of the filter 401, an L-shaped second limiting rod 902 for limiting the second cleaning rod 901 is fixedly installed on the second cleaning rod 901, a limiting groove 903 vertically slidingly matched with the second limiting rod 902 is provided on the filter cartridge 1, a second cleaning groove 905 is provided on the second cleaning rod 901, a first cleaning groove 904 connected to the second cleaning groove 905 through the filter 401 is provided on the first cleaning rod 602, and a water supply component matched with the second cleaning groove 905 is provided on the filter cartridge 1.

[0047] The water supply assembly includes an annular plate 1001 fixedly mounted on the inner wall of the filter screen 401 and the filter cartridge 1, an annular air bag 1002 which is not connected at the head and tail is fixedly mounted on the top wall of the annular plate 1001, a one-way water inlet valve 1003 for absorbing water is inserted into the annular air bag 1002, a one-way drain valve 1004 is inserted into one end of the one-way water inlet valve 1003 of the annular air bag 1002, and a second water pipe 1005 which is connected to the second cleaning tank 905 is inserted into the output end of the one-way drain valve 1004.

[0048] The isolation plate 8 is provided with a spring telescopic rod 1006 for driving the annular airbag 1002 , a mounting frame 1007 is fixedly mounted on the bottom wall of the spring telescopic rod 1006 , and a pressure wheel 1008 for squeezing the annular airbag 1002 is rotatably mounted on the mounting frame 1007 .

[0049] By adopting the above technical solution, the isolation plate 8 is driven to rotate during the rotation of the filter 401. At the same time, the isolation plate 8 can block the sewage trough 404 below the filter 401, thereby effectively preventing impurities in the collection box 402 from entering the filtered water flow.

[0050] In the initial state, the spring telescopic rod 1006 is in a compressed state. Since the second cleaning rod 901 is rotatably matched with the annular groove, and the second cleaning rod 901 is rotatably engaged with the second annular groove, the second cleaning rod 901 and the second annular groove cannot be relatively displaced in the vertical direction, that is, the second cleaning rod 901 is always in contact with the bottom wall of the filter screen 401, and because the second cleaning rod 901 is vertically slidably matched with the limiting groove 903 through the second limiting rod 902, the second cleaning rod 901 cannot be rotated. Then, during the rotation of the filter screen 401, the spring telescopic rod 1006 is driven to rotate through the isolation plate 8. During the rotation of the spring telescopic rod 1006, the pressure wheel 1008 is driven to rotate through the mounting bracket 1007. During the rotation of the pressure wheel 1008, the annular airbag 1002 is squeezed and rolled on the annular airbag 1002. Then, during the reciprocating movement of the filter screen 401 up and down, the spring telescopic rod 1006 contracts back and forth and makes the pressure wheel 1008 always squeeze the annular airbag shaped airbag 1002, and then when the pressure wheel 1008 rolls along the annular airbag 1002, the annular airbag 1002 is stretched on the side opposite to the rolling direction of the pressure wheel 1008 and absorbed by the one-way water inlet valve 1003. At the same time, the annular airbag 1002 is squeezed on the side with the same rolling direction as the pressure wheel 1008. At this time, the water in the annular airbag 1002 on the side with the same rolling direction as the pressure wheel 1008 flows through the one-way drain valve 1004 and the second water pipe 1005 to the second cleaning tank 905, and flows through the second cleaning tank 905, the gap of the filter 401, and the first cleaning tank 904 to the collection box 402. In the process of water flowing through the gap of the filter screen 401, impurities in the gap of the filter screen 401 will be driven to flow through the first cleaning tank 904 to the collection box 402, thereby effectively preventing the gap of the filter screen 401 from being blocked, affecting the speed of water flowing through the filter screen 401, and playing a role in improving the water flow filtration efficiency.

[0051] like Figure 6 As shown, a first fixing groove 11 and a second fixing groove 12 are respectively formed on the side walls of the slide groove 405 , and the first fixing groove 11 is located below the second fixing groove 12 . A fixing rod 13 is provided on the sealing plate 406 and slidably cooperates with the first fixing groove 11 .

[0052] By adopting the above technical solution, when the user needs to block the drain trough 404, the user can first pull the fixing rod 13 to make the fixing rod 13 disengage from the first fixing groove 11, and then push the sealing plate 406 upward through the fixing rod 13. When the sealing plate 406 blocks the drain trough 404, the user can insert the fixing rod 13 into the second fixing groove 12. When the drain trough 404 needs to be opened, the user can again disengage the fixing rod 13 from the second fixing groove 12, and then drive the sealing plate 406 to move downward through the fixing rod 13. When the sealing plate 406 disengages from the drain trough 404, the user can again insert the fixing rod 13 into the first fixing groove 11, which makes it convenient for the user to open or close the drain trough 404.

[0053] Instructions for use: During use, water flows into the filter cartridge 1 through the first water pipe 2, and flows to the next process through the filter screen 401 and the drain pipe 3. In the process of water flowing through the filter cartridge 1, part of the water will flow through the drain trough 404 to the collection box 402 and fill the entire collection box 402. At the same time, in the process of water flowing through the filter screen 401, impurities in the water flow are blocked by the filter screen 401 and enter the collection box 402 along the top wall of the filter screen 401. When it is necessary to clean the impurities, the user can seal the drain trough 404 by moving the sealing plate 406, and then clean the impurities in the collection box 402. In the process of water flowing through the first water pipe 2 and entering the filter cartridge 1, The water flow will impact the impeller 502 to drive the impeller 502 to rotate, and then drive the rotating rod 501 to rotate during the rotation of the impeller 502. During the rotation of the rotating rod 501, the rotating rod 501 drives the linkage block 504 to rotate through the vertical slot 503, and then drives the filter 401 to rotate during the rotation of the linkage block 504. During the rotation of the filter 401, the impurities on the top wall of the filter 401 can be driven to rotate, and then the impurities can be accelerated to approach the edge of the filter 401 under the action of centrifugal force; during the rotation of the rotating rod 501, the filter 401 is driven to reciprocate up and down, and during the reciprocating up and down movement of the filter 401, the impurities on the surface of the filter 401 can be loosened. This facilitates the impurities on the top wall of the filter 401 to move toward the edge of the filter 401 and enter the collection box 402; when the elastic pad 605 is compressed, the gas in the cavity 703 is squeezed and flows to the input end of the pneumatic telescopic rod 701 through the first air pipe 704, and then the output end of the pneumatic telescopic rod 701 extends and drives the cleaning block 702 to move along the side wall of the first cleaning rod. During the movement of the cleaning block 702, the impurities on the side wall of the first cleaning rod can be driven to move into the collection box 402; during the rotation of the filter 401, the spring telescopic rod 1006 is driven to rotate through the isolation plate 8, and during the rotation of the spring telescopic rod 1006, the mounting frame 100 7 drives the pressing wheel 1008 to rotate. During the rotation of the pressing wheel 1008, the annular airbag 1002 is squeezed and rolled on the annular airbag 1002. The water in the annular airbag 1002 located on the same side as the rolling direction of the pressing wheel 1008 flows through the one-way drain valve 1004 and the second water pipe 1005 to the second cleaning tank 905, and flows through the second cleaning tank 905, the gap of the filter 401, and the first cleaning tank 904 to the collection box 402. During the process of water flowing through the gap of the filter 401, the impurities in the gap of the filter 401 are driven to flow through the first cleaning tank 904 to the collection box 402, thereby effectively preventing the gap of the filter 401 from being blocked.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
