Description

Technical Field

[0001] The present invention relates to the field of ion exchange resin regeneration, and more specifically, to a water treatment device for ion exchange resin regeneration. Background Art

[0002] We usually use the index of "hardness" to represent the content of calcium and magnesium ions in water. Water softening is to pass raw water with higher hardness through the ion exchange resin in the resin tank, so that the calcium and magnesium ions in the water are adsorbed by the resin, and at the same time, sodium ions are released. In this way, the water flowing out of the resin tank is softened water.

[0003] When the resin is saturated, that is, it can no longer exchange more ions, regeneration is required. The regeneration process usually uses a salt solution (such as sodium chloride solution) to rinse the resin to restore its exchange ability. During the regeneration process, the sodium ions in the salt solution displace the hardness ions on the resin, so that the resin returns to its initial state.

[0004] In the existing water softening equipment during resin regeneration, the salt solution often enters from the central pipe in the resin tank and rinses it from the bottom of the resin layer. Due to the relatively thick resin layer, this method will cause incomplete cleaning of the resin layer, resulting in insufficient resin regeneration and affecting the subsequent water softening efficiency and water softening quality.

[0005] For example: The "Water Softening Treatment Equipment for Beer Brewing" disclosed in the Chinese invention patent (application number: CN202410338188.4) has its specification disclose that the existing water softening equipment is not thoroughly cleaned during resin reduction, resulting in insufficient resin reduction and affecting the water softening efficiency and water softening quality; the above patent can prove the defects existing in the prior art.

[0006] Therefore, we make improvements on this and propose a water treatment device for ion exchange resin regeneration. Summary of the Invention

[0007] The purpose of the present invention is to address the current problems of insufficient resin regeneration, which affects the subsequent water softening efficiency and water softening quality.

[0008] To achieve the above-mentioned invention purpose, the present invention provides a water treatment device for ion exchange resin regeneration to improve the above problems.

[0009] Specifically, this application is as follows:

[0010] It includes a resin tank and an ion exchange resin layer. A regeneration mechanism for layer-by-layer rinsing of the ion exchange resin layer is provided in the resin tank. The regeneration mechanism includes a regular polygon tube body one and a regular polygon tube body two that are alternately distributed from top to bottom in the resin tank. A circular tube is fixedly connected to the topmost regular polygon tube body one.

[0011] As a preferred technical solution of the present application, the lower edge of the regular polygon tube body one is in an open shape, the regular polygon tube body two extends into the regular polygon tube body one, the upper edge of the regular polygon tube body two fits with the regular polygon tube body one, and except for one regular polygon tube body two at the bottommost, the remaining regular polygon tube bodies two are all fixed on a regular polygon tube body one located below it.

[0012] As a preferred technical solution of the present application, the surface of the regular polygon tube body one is fixedly connected with delivery pipes that are internally interconnected with it and arranged in a circumferential array. At least two spray heads are installed on the surface of the delivery pipes, a one-way liquid outlet valve is installed on the delivery pipes, the side of the regular polygon tube body one away from the delivery pipes is fixedly connected with a liquid inlet pipe that is internally interconnected with it, and a one-way liquid inlet valve is installed on the liquid inlet pipe.

[0013] As a preferred technical solution of the present application, the bottom surface of the inner wall of the resin tank is rotatably connected with an annular seat. An L-shaped rod is fixedly connected between the annular seat and one regular polygon tube body two at the bottommost. The surface of the spray head is rotatably connected with stirring blades.

[0014] As a preferred technical solution of the present application, an annular frame is jointly fixed between the free ends of the delivery pipes located on the same horizontal plane. A filter screen is fixed between two adjacent inclined rods two on the left and right. The other two sides of the filter screen are respectively fixed on the annular frame and the regular polygon tube body one. The ion exchange resin layer is filled between the filter screens adjacent up and down.

[0015] As a preferred technical solution of the present application, a driving device for driving the regular polygon tube body one and the regular polygon tube body two to move up and down is arranged in the resin tank. The driving device includes a tubular driving member inserted at the top end of the resin tank and driven by an external driving device. The tubular driving member is sleeved on the round tube and is threadedly connected with the round tube.

[0016] As a preferred technical solution of the present application, a column of inclined rods one equally spaced from top to bottom and a column of inclined rods two equally spaced from top to bottom are arranged inside the pipeline formed by the regular polygon tube body one and the regular polygon tube body two. The inclined rods one and the inclined rods two are cross-distributed in one-to-one correspondence and are rotatably connected at the intersection positions. The ends of the adjacent inclined rods one and inclined rods two up and down are rotatably connected. Among them, the free ends of the inclined rods one and inclined rods two at the bottommost are rotatably connected to one regular polygon tube body two at the bottommost. Each regular polygon tube body one is coaxially fixed with the intersection of a pair of inclined rods one and inclined rods two.

[0017] As a preferred technical solution of the present application, a linkage mechanism is provided inside the resin tank.

[0018] As a preferred technical solution of the present application, a limiting rod is vertically fixed on the side wall of the round tube. The free end of the limiting rod is adapted to the annular chute one, the annular chute two, and the vertical chute.

[0019] As a preferred technical solution of the present application, two rectangular slots are provided at the diagonal corners of the vertical chute on the limiting frame. Springs are fixedly installed in the rectangular slots. The upper ends of the springs are fixedly installed with clamping blocks. One of the clamping blocks extends into the annular chute one, and the other clamping block extends into the annular chute two. And the sides of the two clamping blocks away from the vertical chute are inclined.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In the solution of the present application:

[0022] 1. In order to solve the problem in the prior art that the resin regeneration is insufficient, affecting the subsequent water quality softening efficiency and water quality softening quality, the present application realizes the stratified flushing of the ion exchange resin layer with a salt solution through the provided regeneration mechanism, rather than always allowing the salt solution to flow upward from the bottom of the ion exchange resin layer, thereby improving the regeneration efficiency and quality of the ion exchange resin layer, and at the same time improving the efficiency and quality of the subsequent water quality softening;

[0023] 2. When the device softens the external water source, the ion exchange resin layer inside needs to accumulate to some extent and cannot be too loose to ensure the softening quality of the water source. In the traditional device, it often relies on the gravity of the ion exchange resin layer itself to fall and accumulate together. In this way, the water flow speed cannot be too fast, which will wash away the ion exchange resin layer and affect the softening effect, resulting in a low softening efficiency of the device;

[0024] The present application can limit the ion exchange resin layer through the provided filter screen. The flow rate of the water source can be slightly faster and the ion exchange resin layer will not be washed away, which can ensure both the softening quality and the softening rate;

[0025] And after the filter screen moves upward, the distance between two adjacent filter screens above and below increases, allowing the ion exchange resin layer to be washed and regenerated by the rapidly flowing salt solution while being washed away, improving the regeneration efficiency;

[0026] After the ion exchange resin layer is flushed at a high speed with a salt solution for a period of time, a part of the ion exchange resin layer has been restored. It is necessary to reduce the amount of salt solution used. Then, the ion exchange resin layer will fall and accumulate due to its own weight. Repeatedly shaking the filter screen up and down can disperse the ion exchange resin layer;

[0027] 3. Through the provided driving device, the up and down movement of the regular polygon tube body one, the regular polygon tube body two, the conveying pipe, and the filter screen is realized. While completing the stratified transportation of the salt solution, the filter screen also shakes the ion exchange resin layer.

[0028] 4. Through the provided linkage mechanism, the rotation state of the conveying pipe is realized, and the conveying pipe stirs the ion exchange resin layer in the salt solution, so as to reduce the use of salt solution while ensuring the regeneration efficiency and reduce the regeneration cost.

[0043] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] As described in the background art, the resin regeneration is insufficient, which affects the subsequent water quality softening efficiency and water quality softening quality.

[0045] To solve this technical problem, the present invention provides an ion exchange resin regeneration type water treatment device, which is applied to a water quality softening device.

[0046] Specifically, please refer to Figure 1 - Figure 5 , the ion exchange resin regeneration type water treatment device specifically includes:

[0047] A resin tank and an ion exchange resin layer. A regeneration mechanism for layer-by-layer flushing of the ion exchange resin layer is arranged in the resin tank. The regeneration mechanism includes a first regular polygon tube body and a second regular polygon tube body that are alternately distributed from top to bottom in the resin tank, and a circular tube is fixedly connected to the topmost first regular polygon tube body.

[0048] The ion exchange resin regeneration type water treatment equipment provided by the present invention realizes the layered flushing of the ion exchange resin layer with a salt solution through the provided regeneration mechanism, rather than always allowing the salt solution to flow upward from the bottom of the ion exchange resin layer, thereby improving the regeneration efficiency and quality of the ion exchange resin layer, and at the same time improving the efficiency and quality of subsequent water softening.

[0049] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0051] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0052] Example 1, please refer to Figure 1 - Figure 6 , an ion exchange resin regeneration type water treatment equipment, including a resin tank 1 and an ion exchange resin layer 2, and a regeneration mechanism 3 for performing layered flushing on the ion exchange resin layer 2 is arranged in the resin tank 1.

[0053] The regeneration mechanism 3 includes a regular polygon tube body one 301 and a regular polygon tube body two 302 that are alternately distributed from top to bottom in the resin tank 1, and a circular tube 303 is fixedly connected to the topmost regular polygon tube body one 301;

[0054] The regular polygon tube body one 301, the regular polygon tube body two 302, and the circular tube 303 in the resin tank 1 form a central pipeline;

[0055] The lower edge of the regular polygon tube body one 301 is in an open shape, the regular polygon tube body two 302 extends into the regular polygon tube body one 301, the regular polygon tube body one 301 and the regular polygon tube body two 302 are telescopic, and the upper edge of the regular polygon tube body two 302 fits with the regular polygon tube body one 301, so that the upper edge of the regular polygon tube body two 302 can act as a piston in the regular polygon tube body one 301, and a closed space is formed in the regular polygon tube body one 301. Except for the lowermost regular polygon tube body two 302, the remaining regular polygon tube bodies two 302 are all fixed on the regular polygon tube body one 301 located below it.

[0056] A delivery pipe 304 that is fixedly connected to the surface of the regular polygon pipe body 301 and is in internal communication with it and arranged in a circumferential array is provided, and at least two spray heads 305 are installed on the surface of the delivery pipe 304;

[0057] By providing the delivery pipes 304 and spray heads 305 distributed layer by layer, the unused salt solution can be transported to different depths of the ion exchange resin layer 2, rather than always allowing the salt solution to flow upward from the bottom of the ion exchange resin layer 2.

[0058] A one-way liquid outlet valve 306 is installed on the delivery pipe 304. A liquid inlet pipe 307 that is fixedly connected to the side of the regular polygon pipe body 301 away from the delivery pipe 304 and is in internal communication with it is provided, and a one-way liquid inlet valve 308 is installed on the liquid inlet pipe 307;

[0059] By providing the liquid inlet pipe 307 and the one-way liquid inlet valve 308, when the enclosed space in the regular polygon pipe body 301 becomes larger, the salt solution in the central pipe formed by the regular polygon pipe body 301, the regular polygon pipe body 302, and the circular pipe 303 can be sucked in;

[0060] By providing the one-way liquid outlet valve 306, when the enclosed space in the regular polygon pipe body 301 becomes smaller, the salt solution in the regular polygon pipe body 301 can be squeezed out and sprayed through the spray heads 305.

[0061] There is only a simple telescopic relationship between the regular polygon pipe body 301 and the regular polygon pipe body 302 at the top layer. During telescoping, it does not constitute a piston movement, and the delivery pipe 304 at the top layer only simply supports the filter screen 3010, and its surface does not have spray heads 305 because there is no ion exchange resin layer 2 above the delivery pipe 304 at the top layer, and there is no need to spray clean salt solution;

[0062] A ring seat 3011 is rotatably connected to the bottom surface of the inner wall of the resin tank 1, and an L-shaped rod 3012 is fixedly connected between the ring seat 3011 and the lowermost regular polygon pipe body 302;

[0063] By providing the ring seat 3011 and the L-shaped rod 3012, the regular polygon pipe body 301 and the regular polygon pipe body 302 can be supported, and the lowermost regular polygon pipe body 302 cannot move up and down.

[0064] Example 2 further optimizes the ion exchange resin regeneration type water treatment equipment provided in Example 1. Specifically, as Figure 1 - Figure 4As shown, a circular frame 309 is fixedly connected between the free ends of the conveying pipes 304 located on the same horizontal plane. A filter screen 3010 is fixedly connected between two adjacent inclined rods II 403 on the left and right. The other two sides of the filter screen 3010 are fixedly connected to the circular frame 309 and the regular polygon pipe body I 301 respectively. The ion exchange resin layer 2 is filled between the adjacent upper and lower filter screens 3010;

[0065] By providing the filter screen 3010, the ion exchange resin layer 2 can be restricted. The flow rate of the water source can be slightly faster without flushing away the ion exchange resin layer 2, which can ensure both the softening quality and the softening rate;

[0066] Moreover, the filter screen 3010 can move up and down following the regular polygon pipe body I 301. After moving upward, the distance between the adjacent upper and lower filter screens 3010 increases, enabling the ion exchange resin layer 2 to be washed and regenerated by the rapidly flowing salt solution while being dispersed, thereby improving the regeneration efficiency;

[0067] After the salt solution flushes the ion exchange resin layer 2 at a high speed for a period of time, a part of the ion exchange resin layer 2 has been restored. When it is necessary to reduce the usage amount of the salt solution, the ion exchange resin layer 2 will fall and accumulate due to its own weight. Repeated up and down shaking of the filter screen 3010 can disperse the ion exchange resin layer 2;

[0068] A stirring blade 3013 is rotatably connected to the surface of the spray head 305;

[0069] When the conveying pipe 304 rotates and stirs the ion exchange resin layer 2, it can drive the stirring blade 3013 to revolve. At the same time, the stirring blade 3013 will also rotate self - rotatably, disturbing the flow direction of the salt solution inside the resin tank 1, thereby further improving the contact between the salt solution and the ion exchange resin layer 2.

[0070] Example 3 further optimizes the ion - exchange resin regeneration type water treatment equipment provided in Example 1 or 2. Specifically, as Figure 2 - Figure 3 shown, a driving device 4 for driving the regular polygon pipe body I 301 and the regular polygon pipe body II 302 to move up and down is arranged inside the resin tank 1.

[0071] The driving device 4 includes a tubular driving member 401 inserted at the top end of the resin tank 1 and driven by an external driving device. The external driving device is an electric push rod, which can drive the tubular driving member 401 to move along the vertical direction. The tubular driving member 401 is sleeved on the round tube 303 and is threadedly connected to the round tube 303. When the round tube 303 is not restricted externally, it can move up and down following the tubular driving member 401. When the round tube 303 is restricted externally and cannot move upward or downward, it will rotate following the up and down movement of the tubular driving member 401.

[0072] Inside the pipeline formed by the regular polygon tube body one 301 and the regular polygon tube body two 302, there is a row of inclined rods one 402 evenly distributed from top to bottom, and a row of inclined rods two 403 also evenly distributed from top to bottom. The inclined rods one 402 and the inclined rods two 403 are cross-distributed in one-to-one correspondence and are rotatably connected at the intersection positions, and the ends of the adjacent inclined rods one 402 and inclined rods two 403 from top to bottom are rotatably connected;

[0073] Among them, the free ends of the lowermost inclined rod one 402 and inclined rod two 403 are rotatably connected to the lowermost regular polygon tube body two 302, and each regular polygon tube body one 301 is coaxially fixed to the intersection of a pair of inclined rods one 402 and inclined rods two 403;

[0074] By providing the inclined rod one 402 and the inclined rod two 403, it is convenient to drive all the regular polygon tube bodies one 301 and regular polygon tube bodies two 302 to move up and down simultaneously while driving one of the regular polygon tube bodies one 301 or regular polygon tube bodies two 302 to move up and down.

[0075] Embodiment 4 further optimizes the ion exchange resin regenerative water treatment equipment provided in the above embodiments, such as Figure 7 and Figure 8 As shown, a linkage mechanism 5 is arranged inside the resin tank 1 for restricting the movement of the round tube 303.

[0076] The linkage mechanism 5 includes a limiting frame 501 integrally fixed on the inner wall of the resin tank 1. The surface of the limiting frame 501 is provided with an upper and lower distributed annular sliding groove one 502 and annular sliding groove two 503, and a vertical groove 504 located between the annular sliding groove one 502 and the annular sliding groove two 503 and communicating with each other. A limiting rod 505 is vertically fixed on the side wall of the round tube 303, and the free end of the limiting rod 505 is adapted to the annular sliding groove one 502, the annular sliding groove two 503, and the vertical groove 504.

[0077] When the limiting rod 505 is in the vertical groove 504, the round tube 303 can only move up and down;

[0078] When the limiting rod 505 is within the first annular sliding groove 502 or the second annular sliding groove 503, the circular tube 303 can rotate;

[0079] Two rectangular grooves 506 are formed at the diagonal positions of the vertical groove 504 on the limiting frame 501. A spring 507 is fixedly installed within the rectangular groove 506, and an upper end of the spring 507 is fixedly installed with a clamping block 508;

[0080] One of the clamping blocks 508 extends into the first annular sliding groove 502, and the other clamping block 508 extends into the second annular sliding groove 503. One sides of the two clamping blocks 508 away from the vertical groove 504 are inclined;

[0081] By providing two clamping blocks 508, the limiting rod 505 can only rotate clockwise within the first annular sliding groove 502, while the limiting rod 505 can only rotate counterclockwise within the second annular sliding groove 503.

[0082] The usage process of the ion exchange resin regenerative water treatment equipment provided by the present invention is as follows:

[0083] Working principle:

[0084] Since the ion exchange resin layer 2 is filled between the upper and lower adjacent filter meshes 3010, in the initial state, the upper and lower adjacent filter meshes 3010 restrict the ion exchange resin layer 2, causing the ion exchange resin layer 2 to accumulate together. When softening hard water, even if the water flow rate is slightly faster, the ion exchange resin layer 2 will not be washed away, ensuring both the softening quality and the softening rate;

[0085] When it is necessary to regenerate the ion exchange resin layer 2, an external electric push rod drives the tubular driving member 401 to move upward. Since the free end of the limiting rod 505 is within the vertical groove 504 at this time, the tubular driving member 401 can drive the circular tube 303 to move upward accordingly, and the circular tube 303 can drive a first regular polygon tube body 301 fixedly connected thereto to move upward;

[0086] Through the first inclined surface rod 402 and the second inclined surface rod 403, all the first regular polygon tube bodies 301 and the second regular polygon tube bodies 302 can be moved upward, and at the same time, the distance between the upper and lower adjacent filter meshes 3010 is enlarged;

[0087] At this time, the salt solution used for regenerating the ion exchange resin layer 2 enters the resin tank 1 through the central pipeline formed by the first regular polygon tube body 301, the second regular polygon tube body 302, and the circular tube 303, and flows upward from the bottom of the ion exchange resin layer 2 to wash away the ion exchange resin layer 2 for rapid regeneration;

[0088] Then, the circular tube 303 is driven to move up and down by the tubular driving member 401, and the regular polygon tube body one 301 and the regular polygon tube body two 302 also move up and down simultaneously;

[0089] When the sealed space in the regular polygon tube body one 301 becomes larger, the salt solution in the central pipeline formed by the regular polygon tube body one 301, the regular polygon tube body two 302, and the circular tube 303 can be inhaled through the liquid inlet pipe 307 and the one-way liquid inlet valve 308;

[0090] When the sealed space in the regular polygon tube body one 301 becomes smaller, the salt solution in the regular polygon tube body one 301 can be extruded through the one-way liquid outlet valve 306 and sprayed out through the nozzle 305, so as to wash the ion exchange resin layer 2 in layers and improve the regeneration efficiency of the ion exchange resin layer 2;

[0091] At the same time, the filter screen 3010 also moves up and down with the regular polygon tube body one 301. Then, when the filter screen 3010 moves up and down, it can play a role in shaking the ion exchange resin layer 2 loose. While the flow rate of the salt solution slows down, the ion exchange resin layer 2 will not accumulate downward together, which is more conducive to the regeneration of the ion exchange resin layer 2;

[0092] In order to further improve the utilization rate of the salt solution, finally, the resin tank 1 can be filled with the salt solution, and the ion exchange resin layer 2 can be soaked in the salt solution. At this time, the salt solution is in a non-flowing state;

[0093] The tubular driving member 401 is driven to move upward by an external electric push rod. The tubular driving member 401 drives the circular tube 303 to move upward. After the circular tube 303 drives the limiting rod 505 to move upward into the annular sliding groove one 502, the circular tube 303 is restricted and can only rotate clockwise, thereby driving the regular polygon tube body one 301, the regular polygon tube body two 302, the conveying pipe 304, and the filter screen 3010 to rotate accordingly. The conveying pipe 304 acts as a stirring rod during rotation to stir the ion exchange resin layer 2 and the salt solution, so that the ion exchange resin layer 2 is fully regenerated;

[0094] At the same time, the conveying pipe 304 can drive the stirring blade 3013 to revolve, and the stirring blade 3013 will also rotate self - concurrently, disturbing the flow direction of the salt solution inside the resin tank 1, thereby being able to further improve the contact between the salt solution and the ion exchange resin layer 2;

[0095] When the ion exchange resin layer 2 is regenerated, the tubular driving member 401 moves downward. The circular tube 303 and the limiting rod 505 rotate counterclockwise to above the vertical groove 504 and are blocked by the clamping block 508. They can only move downward along the vertical groove 504 into the annular sliding groove two 503, and then continue to rotate counterclockwise until the tubular driving member 401 returns to its original position.
