DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 of the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1 — Figure 7 As shown, a municipal water supply treatment and filtering device comprises a first filter box 101 and a second filter box 102, the top and bottom of the first filter box 101 and the second filter box 102 are respectively connected with an upper connecting pipe 103 and a lower connecting pipe 104 by bolts, a processing mechanism is installed on the opposite side of the lower connecting pipe 104, the first filter box 101 and the second filter box 102 are provided with a filtering mechanism and a sealing mechanism, the filtering mechanism comprises a lifting block 301, the lifting block 301 is slidably connected in the first filter box 101 and the second filter box 102, a filter screen 302 is detachably connected to the lifting block 301, a groove for inserting the filter screen 302 is provided on the lifting block 301, after the filter screen 302 is inserted into the lifting block 301, it can move synchronously with the lifting block 301, and an elastic component is fixedly installed on the top of the lifting block 301, and the elastic component is used to prevent the lifting block 301 moves downward under the impact of the water flow. When the filter screen 302 filters water under normal conditions, the filter screen 302 is impacted by the water flow and moves downward a certain distance. As the amount of filtration increases, the filter residues gathered on the filter screen 302 increase, and it will gradually fail and become concave. At this time, it will move downward a longer distance. Then, the water flow from the water distribution box 401 to the first filter box 101 can be reduced through the adjustment mechanism. The staff needs to replace the filter screen 302 in time. A water distribution mechanism is installed on the upper connecting pipe 103. The water distribution mechanism includes a water distribution box 401. A drawing pipe 403 is slidably connected in the water distribution box 401. The drawing pipe 403 is provided with a first water outlet 404 and a second water outlet 405. One end of the drawing pipe 403 is connected to a sliding rod 407 by bolts. The sliding rod 407 is slidably connected to the water distribution box 401 and extends from the inside to the outside.

[0029] The first filter box 101 and the second filter box 102 are provided with an adjustment mechanism, and the adjustment mechanism includes a rocker 501, which is rotatably connected to one side of the first filter box 101 and the second filter box 102 respectively, and a swing arm 502 is connected to the rocker 501 by bolts, and the end of the rocker 501 is arranged close to the bottom of the filter screen 302, and a connecting assembly is provided on the swing arm 502, and the connecting assembly is used to connect the two sets of swing arms 502 and the slide bar 407. When the filter screen 302 gradually fails, the residual filter residue on the filter screen 302 increases, and the impact force of the water flow on the filter screen 302 becomes greater, so that it moves downward, pressing the rocker 501, and the rocker 501 drives the swing arm 502 to rotate, so that the connecting assembly can push the slide bar 407, and the slide bar 407 drives the pull-out tube 403 to move, thereby adjusting the water flow entering the first filter box 101.

[0030] In this embodiment, the processing mechanism includes a three-way pipe 201, in which a one-way valve 202 is fixedly installed. The three-way pipe 201 is connected to the inner sides of the two lower connecting pipes 104 by bolts. The bottom of the three-way pipe 201 is connected to a processing box 203 by bolts, and an activated carbon layer and a sterilization layer are arranged inside the processing box 203.

[0031] In this embodiment, the connecting component includes a push-pull frame 503, and the connecting components arranged on the first filter box 101 and the second filter box 102 are centrally symmetrical. The push-pull frame 503 is mounted on the swing arm 502, so that when the swing arm 502 swings, the push-pull frame 503 can move translationally. The push-pull frame 503 is connected to a push rod 504 by bolts, and a guide block 505 is slidably connected to the push rod 504. The guide block 505 is connected to the side of the first filter box 101 and the second filter box 102 by bolts. The end of the push rod 504 away from the push-pull frame 503 is connected to an S-shaped connecting rod 506 by bolts, and the middle section of the S-shaped connecting rod 506 is connected to an adjusting rod 507 by bolts, and the adjusting rod 507 is connected to the sliding rod 407 by bolts.

[0032] In this embodiment, the adjustment mechanism includes a limit rod 508, which is rotatably connected to the water distribution box 401. The limit rod 508 is used to limit the adjustment rod 507 when replacing the filter screen.

[0033] In this embodiment, the elastic component includes a connecting block 303, the top of the connecting block 303 is connected to a connecting rod 304 by bolts, a fixing sleeve 305 is slidably connected to the connecting rod 304, the fixing sleeve 305 is connected to the top of the first filter box 101 and the second filter box 102 by bolts, and a spring 306 is installed between the connecting rod 304 and the fixing sleeve 305. The setting of the spring 306 hinders the action of water flow impacting the filter screen 302 to cause it to descend, thereby preventing the filter screen 302 from directly pressing down the rocker 501, thereby ensuring the normal use of the filter screen 302 and the adjustment mechanism.

[0034] In this embodiment, the filter screen 302 includes a filter frame and an inner mesh structure. The inner mesh structure is a shape that bulges from the edge to the middle, and is used to move the filter residue around. The lifting block 301 is slidably connected to the filter frame. The filter residue on the inner mesh structure of the filter screen 302 will be washed around by the water flow. However, after a period of use, the filter residue will be stuck on the filter screen 302, and the filter screen 302 will also be concave due to the force, and it will eventually be difficult to meet the filtering requirements, so the filter screen 302 needs to be replaced.

[0035] In this embodiment, a water supply pipe 402 is connected to the side of the water distribution box 401 by bolts, and the water distribution box 401 has a T-shaped cavity. The first water outlet 404 and the second water outlet 405 on the pulling tube 403 are respectively opened on opposite sides, and the area of ​​the first water outlet 404 is larger than the area of ​​the second water outlet 405. Two baffle plates 406 are connected to the water distribution box 401 by bolts, and the two baffle plates 406 are respectively located at the first water outlet 404 and the second water outlet 405. The direction of the first water outlet 404 makes water flow to the first filter box 101, and the water at the outlet of the second water outlet 405 flows to the second filter box 102. The baffle plates 406 The pulling tube 403 is configured so that it can limit the flow rate of the first water outlet 404 and the second water outlet 405 when moving. Since the area of ​​the first water outlet 404 is larger than that of the second water outlet 405, more water will flow to the first filter box 101, and then the failure rate of the filter screen 302 in the first filter box 101 is faster than the failure rate of the filter screen 302 in the second filter box 102. When the filter screen 302 in the first filter box 101 fails, it is necessary to guide all the water flow to the second filter box 102, replace the filter screen 302 in the first filter box 101, and then keep the device in normal operation.

[0036] In this embodiment, the sealing mechanism includes a fixing frame 601, and openings are provided on the sides of the first filter box 101 and the second filter box 102. The fixing frame 601 is connected to the sides of the first filter box 101 and the second filter box 102 by bolts. A sealing plate 602 is inserted into the fixing frame 601, and a waterproof block 603 is glued to the side of the sealing plate 602. The waterproof block 603 can seal the side openings of the first filter box 101 and the second filter box 102 to prevent water from seeping out.

[0037] Working principle: When the device is in use, the water flow to be treated enters the water distribution box 401 through the water supply pipe 402, and the water flows from the water supply pipe 402 into the drawing pipe 403, and is diverted to the upper connecting pipe 103 through the first water outlet 404 and the second water outlet 405, and flows to the first filter box 101 and the second filter box 102 respectively. When the filter screen 302 filters water under normal conditions, the filter screen 302 is impacted by the water flow and moves downward a certain distance, the spring 306 is compressed for a certain distance, and the inner mesh structure of the filter screen 302 is convex from the edge to the middle. The filter residue on the inner mesh structure of the filter screen 302 will be washed around by the water flow, which prevents the filter residue from being stuck in the filter screen 302 to a certain extent. After the water flow is filtered by the filter screen 302, it enters the three-way pipe 201 through the lower connecting pipe 104, and then enters the next treatment step after being processed by the treatment box 203.

[0038] As the device is used, the filtration volume increases. Since the area of ​​the first water outlet 404 is larger than the area of ​​the second water outlet 405, more water will flow to the first filter box 101. The residual filter residue on the filter screen 302 on the first filter box 101 increases, and the failure rate is greater than the failure rate of the filter screen 302 in the second filter box 102. The impact force of the water flow it receives becomes greater, so it moves downward, pressing down the rocker 501, and the rocker 501 drives the swing arm 502 to rotate. The swing arm 502 pushes the push-pull frame 503 to move, and the push-pull frame 503 pushes the push rod 504. The push rod 504 pushes the S-shaped connecting rod 506. Since the other end of the S-shaped connecting rod 506 is subjected to less force, the S-shaped connecting rod 506 pushes the sliding rod 407, and the sliding rod 407 drives the pulling tube 403 to move, so that the first water outlet 404 is partially blocked by the blocking plate 406, reducing the amount of water entering the first filter box 10 1, and then with the use of the device, the filter screen 302 in the first filter box 101 is completely ineffective. At this time, the adjusting rod 507 is at the maximum position away from the water distribution box 401, and the filter screen 302 needs to be replaced. The staff rotates the limit rod 508 on the water distribution box 401 to jam the adjusting rod 507, limit the position of the pulling tube 403, and make all the water flow out through the second water outlet 405. When replacing the filter screen 302, the sealing plate 602 is pulled out from the fixing frame 601, the connecting rod 304 is lifted, and then the filter screen 302 is pulled out from the side of the first filter box 101, and the new filter screen 302 is taken out, inserted into the water distribution box 401 and docked into the inner side of the lifting block 301. After the replacement is completed, the sealing plate 602 is reinserted into the inner position of the fixing frame 601, so that the waterproof block 603 seals one side of the first filter box 101, and the device continues to be used normally.

[0039] When the filter screen 302 in the second filter box 102 fails and needs to be replaced, the staff pushes the adjusting rod 507 to make the sliding rod 407 at the minimum position away from the water distribution tank 401, and rotates the limiting rod 508 to limit the adjusting rod 507. At this time, the water flows completely out through the first water outlet 404. The filter screen 302 in the second filter box 102 is replaced according to the same operation, and the device can continue to be used normally.

[0040] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
