Description

Technical Field

[0001] The present invention relates to the technical field of soft water treatment, and particularly relates to a soft water treatment device. Background Art

[0002] Soft water treatment is a water treatment technology that removes hardness ions such as calcium and magnesium in water, reduces water quality hardness, and prevents the formation of water scale. Soft water treatment relies on the ion exchange function of resin to remove calcium and magnesium ions, and needs to be combined with equipment such as a controller, a resin tank, and a salt box to achieve automatic operation. In addition, the resin needs to be regenerated with salt regularly to maintain the softening ability.

[0003] A patent document with the publication number CN117185418B discloses an integrated soft water treatment device, which includes a salt box, a resin tank, and a multi-way valve. A partition one is fixedly arranged on the inner wall of the salt box, and the partition one divides the salt box into a salt storage cavity and a melting cavity. A partition two is fixedly arranged in the melting cavity, and the partition two divides the melting cavity into a purified water cavity and a brine cavity; an outlet is opened on the partition one, a sealing plate slides on the partition one, and a limiting block for limiting the sealing plate is slid on the partition one. A first driving component is arranged in the purified water cavity; a purified water pipe is arranged between the multi-way valve and the purified water cavity; a reaction barrel slides in the brine cavity, a pump body is installed in the reaction barrel, and a salt suction pipe is arranged between the pump body and the multi-way valve; a water outlet is opened on the partition two; a control component for driving the sealing plate to move is also arranged in the salt box. By controlling the melting amount of salt blocks, the crystallization of salt blocks at the bottom of the reaction barrel is reduced.

[0004] However, the following problems still exist in this solution. When using a resin softening tank to treat hard water, impurities carried in the hard water will adhere to the surface of the resin, causing the surface layer of the resin to be blocked. For example, impurities such as suspended solids and colloids in the water cover the surface of the resin particles, forming a dense pollution layer, increasing the water flow resistance and blocking the resin micropores, resulting in uneven water flow distribution and the formation of channeling in the resin, so that part of the resin cannot contact the hard water, resulting in a poor softening effect of the hard water and affecting the softening efficiency. At this time, if the resin is cleaned by backwashing, because only the surface layer is blocked, frequent backwashing is required, seriously affecting the work efficiency. In addition, if the backwashing is insufficient for a long time, the surface of the resin layer will form a hard block, further restricting the water flow through and affecting the treatment effect. Summary of the Invention

[0005] The present invention provides a soft water treatment device, aiming to solve the problem in the related technology that the contact between the resin and the hard water is insufficient due to impurities adhering to the surface of the resin, resulting in the reduction of treatment efficiency.

[0006] The soft water treatment device of the present invention includes a tank body. Inside the tank body, there is a filling cylinder filled with resin. The filling cylinder includes a fixed part fixedly connected to the tank body and a sliding part located above the fixed part and slidably matched with the fixed part up and down. The outer side of the sliding part is arranged at an interval from the inner wall of the tank body to form a collection cavity. An adjusting component and a cleaning component are arranged inside the tank body. The adjusting component cooperates with the sliding part to drive it to move up and down. The cleaning component includes a pressing plate, a scraping plate, and a control part. The pressing plate is located at the upper end of the sliding part, and the scraping plate is located below the pressing plate. A plurality of through holes for water to pass through are opened on the pressing plate. The control part is respectively connected to the scraping plate and the pressing plate to drive the pressing plate to move up and down and the scraping plate to rotate. The clogging layer on the upper surface of the resin is located between the pressing plate and the resin. The adjusting component drives the sliding part to move downward so that the upper end of the sliding part is lower than the clogging layer of the resin. The control part drives the scraping plate to rotate to scrape the clogging layer into the collection cavity, and then drives the pressing plate to move downward to cooperate with the upper end of the sliding part again.

[0007] Hard water is introduced from the upper part of the tank body and finally discharged from the bottom of the tank body after passing through the filling cylinder. The resin in the filling cylinder softens the hard water. The impurities in the hard water will stay on the upper surface of the resin, that is, below the pressing plate. When there are more impurities, a clogging layer is formed on the surface of the resin. When it is necessary to clean the clogging layer, the adjusting component drives the sliding part to move downward so that the upper end of the sliding part is lower than the clogging layer. At the same time, the pressing plate is separated from the sliding part. At this time, the pressing plate abuts against the upper surface of the resin, that is, the clogging layer. The control part drives the scraping plate to rotate to scrape the clogging layer and part of the resin into the collection cavity. At this time, the clogging layer below the pressing plate is eliminated. Then the control part drives the pressing plate to move downward again to cooperate with the sliding part. Repeating this way, the clogging layer on the upper surface of the resin can be continuously cleaned to ensure sufficient contact between the hard water and the resin, reduce the frequency of resin regeneration treatment, and improve the softening efficiency.

[0008] Preferably, the control part includes a control rod, a first driving part, a connecting ring, and an intermediate part. The control rod is rotatably assembled inside the tank body. The first driving part is arranged on the tank body. The output end of the first driving part is connected to the control rod to drive the control rod to rotate. The connecting ring is slidably assembled up and down on the control rod. The connecting ring is rotatably matched with the pressing plate. The pressing plate is slidably assembled up and down inside the tank body. The pressing plate is connected to the control rod through the intermediate part. When the control rod rotates, it drives the pressing plate to move up and down and simultaneously drives the scraping plate to rotate synchronously through the connecting ring.

[0009] The first driving part drives the control rod to rotate. The control rod drives the scraping plate to rotate synchronously through the connecting ring to scrape off the clogging layer on the upper surface of the resin. Then it drives the pressing plate to move downward through the intermediate part so that after the clogging layer is cleaned, the pressing plate cooperates with the sliding part again.

[0010] Preferably, the middleware includes: an intermediate ring sleeved outside the control rod, and a first elastic member disposed between the intermediate ring and the pressing plate. The intermediate ring is disposed on the side of the pressing plate away from the scraping plate. A first threaded groove is formed on the control rod, and the intermediate ring is in threaded engagement with the first threaded groove. Rotation of the control rod drives the intermediate ring to move up and down, and the intermediate ring drives the pressing plate to move up and down through the first elastic member.

[0011] When the control rod drives the scraping plate to clean the clogging layer, it drives the intermediate ring to move downward synchronously. However, at this time, the scraping plate does not scrape off the clogging layer, and the lower part of the pressing plate remains in contact with the clogging layer. The intermediate ring moves relative to the pressing plate and simultaneously compresses the first elastic member. After scraping off the clogging layer, the first elastic member drives the pressing plate to move downward to cooperate with the sliding portion.

[0012] Preferably, the adjusting assembly includes: a second driving member, a screw rod, and an adjusting ring. The second driving member is disposed inside the tank body, and the output end of the second driving member is connected to the screw rod. The adjusting ring is slidably assembled up and down inside the tank body. The screw rod is in threaded engagement with the adjusting ring, and the adjusting ring is sleeved outside the sliding portion. A first retaining ring is disposed at the bottom of the adjusting ring, and the retaining ring is in sliding fit with the outer side of the sliding portion. A second retaining ring is disposed on the outer side of the sliding portion, and the second retaining ring is located below the first retaining ring. An elastic telescopic rod is disposed below the sliding portion, and the elastic telescopic rod is connected to the tank body to drive the sliding portion to move upward.

[0013] The second driving member drives the adjusting ring to move downward through the screw rod. The downward movement of the adjusting ring drives the first retaining ring to abut against the second retaining ring, thereby driving the sliding portion to move downward. Each time it is necessary to clean the clogging layer, the sliding portion is driven to move downward by a certain distance, and then the above operation is repeated.

[0014] Preferably, a backwashing assembly is disposed on one side of the tank body. The backwashing assembly includes: a salt tank, a water inlet pipe, and a water outlet pipe. Both the water inlet pipe and the water outlet pipe are communicated with the salt tank. An installation ring is disposed inside the tank body, and the installation ring is located above the sliding portion. The water inlet pipe is communicated with the bottom of the fixing portion, and the water outlet pipe passes through the tank body and is communicated with the inside of the installation ring. A hard water pipe for introducing hard water is disposed on the tank body, and the water outlet end of the hard water pipe is located above the installation ring.

[0015] The brine enters the tank body through the inlet, then flows upward from the lower part of the tank body, passes through the resin during the process, regenerates the resin, and finally is discharged through the outlet pipe.

[0016] Preferably, an auxiliary plate is slidably disposed up and down inside the fixing portion. A plurality of auxiliary holes for water to pass through are formed on the auxiliary plate. A second threaded groove is formed on the control rod, and the control rod is in threaded engagement with the auxiliary plate through the second threaded groove.

[0017] Reverse rotation of the control rod drives the auxiliary plate to move upward, relieving the pressure applied to the resin inside the fixing portion, causing the resin to rebound and increasing the gap between the resins. When the brine backwashes the resin, it enables the brine to be in full contact with the resin, improving the regeneration effect of the resin.

[0018] Preferably, an annular groove 1 connected to the thread groove 1 and an annular groove 2 connected to the thread groove 2 are coaxially opened on the outer side of the control rod. The annular groove 1 is located at the upper end of the thread groove 1, and two annular grooves 2 are arranged at both ends of the thread groove 2.

[0019] The middle ring stops moving when it moves to the first position of the annular groove, and the auxiliary plate stops moving when it moves to the second position of the annular groove, so that when the control rod drives the pressure plate to move downward, the auxiliary plate is at the second position of the annular groove. At this time, the auxiliary plate is fixed, reducing the mutual interference between the pressure plate and the auxiliary plate.

[0020] Preferably, an auxiliary sleeve is provided in the auxiliary plate, and the auxiliary sleeve is provided on the outside of the control rod. The auxiliary sleeve is provided with elastic member 2 and a connecting plate. The connecting plate is slidably assembled in the auxiliary sleeve, and the connecting plate cooperates with the second thread groove. The elastic member 2 is respectively connected to the connecting plate and the auxiliary sleeve, and the elastic member 2 is used to drive the connecting plate to move upward.

[0021] When the control rod drives the pressure plate to move downward, the connecting plate always cooperates with the second annular groove. When the control rod rotates in the opposite direction, the second elastic member drives the connecting plate to move upward and cooperate with the second threaded groove. At this time, the control rod can drive the auxiliary plate to rotate in the opposite direction, and after the auxiliary plate moves to a certain distance, the connecting plate cooperates with another second annular groove, and the auxiliary plate stops moving. At this time, the auxiliary plate is completed.

[0022] Preferably, a guide slope is provided on the top of the retaining ring 1, and the guide slope is inclined downward near the side of the sliding part.

[0023] During backflushing, the adjustment ring moves upward, driving the resin in the collection frame to enter the sliding part again. At the same time, the direction in which the resin enters the sliding part is opposite to the direction of the backflushing water flow, thereby improving the flushing effect on the resin and flushing out the impurities contained in the resin and discharging them outside the tank.

[0024] Preferably, the outside of the control rod is slidably assembled with a mounting sleeve, the middle ring is slidably assembled in the mounting sleeve, the lower end of the mounting sleeve is fixedly connected to the pressure plate, a plurality of support rods are circumferentially arranged on the outside of the mounting sleeve, a support slide rail is arranged in the mounting ring, and the end of the support rod facing away from the mounting sleeve is slidably matched with the support slide rail.

[0025] The support rod cooperates with the support rail to support the mounting sleeve through the support rail and the support rod. At the same time, the mounting sleeve is fixedly connected to the pressure plate, thereby improving the stability of the pressure plate when it moves up and down.

[0026] Beneficial effects: The present invention is provided with a sliding part and a fixed part that are slidably matched, and a pressing plate and a scraping plate are arranged on the sliding part. When it is necessary to clean the clogging layer on the surface of the resin, the adjusting frame drives the sliding part to move downward, so that the upper end of the sliding part is lower than the clogging layer. Then, after the scraping plate scrapes the clogging layer into the collection cavity, the pressing plate moves downward again to cooperate with the sliding part, completing one cleaning of the clogging layer. Repeating this process can achieve multiple cleanings of the clogging layer on the upper surface of the resin, reducing the frequency of resin regeneration treatment, and at the same time increasing the contact area between hard water and resin, improving the softening efficiency.

[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] As Figures 1 to 9 shown, the soft water treatment device of the present invention includes a tank body 1 and a backwash assembly 2 arranged on one side of the tank body 1. Inside the tank body 1, there are arranged: a filling cylinder 3, an adjustment assembly 4, and a cleaning assembly 5. The filling cylinder 3 is filled with resin for softening hard water. The filling cylinder 3 includes a fixed part 31 and a sliding part 32. The fixed part 31 is fixedly connected to the tank body 1, and the sliding part 32 is slidably matched with the fixed part 31 up and down. The sliding part 32 is arranged at the upper end of the fixed part 31. The adjustment assembly 4 cooperates with the sliding part 32 to adjust the position of the sliding part 32, and the cleaning assembly 5 is used to clean the clogging layer on the surface of the resin.

[0039] The sliding part 32 is arranged at an interval from the inner wall of the tank body 1, and a collection chamber 11 for collecting clogging substances is formed between the sliding part 32 and the tank body 1.

[0040] When treating hard water, the hard water passes through the resin in the sliding part 32 and the fixed part 31 in sequence for softening treatment. The impurities in the hard water will accumulate on the upper surface of the resin to form a clogging layer, that is, the clogging layer is close to the upper end of the sliding part 32. When it is necessary to clean the clogging layer, the adjustment assembly 4 drives the sliding part 32 to move downward so that the upper end of the sliding part 32 is lower than the clogging layer of the resin, and then the cleaning assembly 5 cleans the clogging layer and at the same time clears the clogging layer into the collection box to eliminate the influence of the clogging on the upper surface of the resin and improve the softening efficiency. By repeating the above operations, the clogging layer on the surface of the resin can be cleaned multiple times. After using for a period of time, the resin is regenerated by the backwash assembly 2 to maintain the softening ability of the resin.

[0041] Refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 ,the cleaning component 5 includes: a pressing plate 51, a scraping plate 52, and a control member 53. The pressing plate 51 is located at the upper end of the sliding portion 32 and contacts the upper surface of the resin. The scraping plate 52 is located below the pressing plate 51. A plurality of through holes are evenly formed in the pressing plate 51 for hard water to pass through. The control member 53 is connected to the pressing plate 51 and the scraping plate 52. The control member 53 drives the pressing plate 51 to move up and down, drives the scraping plate 52 to rotate, and the rotation axis of the scraping plate 52 is on the same straight line as the center of the sliding portion 32.

[0042] In this embodiment, the diameter of the through holes in the pressing plate 51 is relatively large, which will not filter the impurities in the hard water, and will not affect the flow of the hard water. It only allows the hard water to pass through. After the hard water passes through the through holes, it contacts the resin. The clogging layer on the resin is located between the pressing plate 51 and the resin, that is, below the pressing plate 51.

[0043] Refer to Figure 5 、 Figure 6 ,when it is necessary to clean the clogging layer, the sliding portion 32 moves so that its upper end is located below the clogging layer. At this time, the pressing plate 51 is separated from the sliding portion 32, and then the control member 53 drives the scraping plate 52 to rotate, scraping off the clogging layer and the upper surface of the resin to clean the clogging layer. After cleaning, the pressing plate 51 is driven to move downward so that the pressing plate 51 is again located above the sliding portion 32 to press the resin. In this way, the clogging layer on the surface of the resin is repeatedly cleaned to ensure sufficient contact between the hard water and the resin.

[0044] Refer to Figure 3 、 Figure 5 、 Figure 6 ,the control member 53 includes: a control rod 531, a first driving member 532, a connecting ring 533, and an intermediate member 534. The control rod 531 is arranged in the vertical direction, and the control rod 531 is rotatably assembled in the tank body 1. The control rod 531 and the center of the sliding portion 32 are on the same straight line. The first driving member 532 is set as a motor, and the output end of the first driving member 532 is connected to the control rod 531 to drive the control rod 531 to rotate. The connecting ring 533 is sleeved outside the control rod 531, and the connecting ring 533 is slidably assembled up and down on the control rod 531. A chute 6 is formed in the control rod 531 in the vertical direction, and the connecting ring 533 is slidably matched with the chute 6, that is, the connecting ring 533 is slidably matched with the control rod 531 through the chute 6. The scraping plate 52 is connected to the side surface of the connecting ring 533, and a plurality of scraping plates 52 are arranged around the connecting ring 533. The pressing plate 51 is slidably assembled up and down in the tank body 1. The intermediate member 534 is arranged between the pressing plate 51 and the control rod 531, and the pressing plate 51 is connected to the control rod 531 through the intermediate member 534.

[0045] The driving member 532 drives the control rod 531 to rotate. The rotation of the control rod 531 drives the connecting ring 533 to rotate synchronously, and then drives the scraper 52 to rotate synchronously to scrape off the clogging layer on the upper surface of the resin. After scraping off the clogging layer, the intermediate member 534 drives the pressing plate 51 to move downward, so that the pressing plate 51 cooperates with the sliding portion 32 again.

[0046] Referring to Figure 6 , the intermediate member 534 includes: an intermediate ring 535 and a first elastic member 536. The intermediate ring 535 is sleeved on the outside of the control rod 531 and slides up and down. The first elastic member 536 is set as a spring. The intermediate ring 535 is located above the pressing plate 51, and the first elastic member 536 is located between the intermediate ring 535 and the pressing plate 51. The first elastic member 536 is respectively connected to the pressing plate 51 and the intermediate ring 535. A first threaded groove 61 is circumferentially formed on the outer side of the control rod 531. The first threaded groove 61 is arranged in the vertical direction. The intermediate ring 535 is in threaded cooperation with the first threaded groove 61, that is, when the control rod 531 rotates, it can drive the intermediate ring 535 to move up and down.

[0047] After the sliding portion 32 moves downward, at this time, the pressing plate 51 is in contact with the upper surface of the resin. When the control rod 531 drives the scraper 52 to rotate, the pressing plate 51 remains stationary under the action of the resin. At the same time, the intermediate ring 535 moves downward close to the pressing plate 51, and at the same time compresses the first elastic member 536, applying a downward force on the pressing plate 51. After the scraper 52 scrapes off the upper surface of the resin, the first elastic member 536 drives the pressing plate 51 to move downward so that the pressing plate 51 can move again to cooperate with the sliding portion 32.

[0048] Referring to Figure 6 , the connecting ring 533 is rotationally matched with the pressing plate 51, that is, the connecting ring 533 can rotate with the control rod 531 under the pressing plate 51 and can also move up and down with the pressing plate 51. When the pressing plate 51 moves downward, it drives the scraper 52 to move synchronously to clean the clogging layer on the resin surface again.

[0049] Referring to Figure 2 、 Figure 3 , an installation ring 7 is arranged in the tank body 1. The installation ring 7 is arranged above the sliding portion 32. A support slide rail 71 is arranged in the installation ring 7. The support slide rail 71 is arranged in the vertical direction.

[0050] Referring to Figure 2 、 Figure 3 、 Figure 6 , an installation sleeve 72 is slidably assembled up and down on the outside of the control rod 531. The intermediate ring 535 is slidably assembled in the installation sleeve 72. The installation sleeve 72 is arranged above the pressing plate 51, and the lower end of the installation sleeve 72 is fixedly connected to the pressing plate 51. A plurality of support rods 73 are arranged on the outer circumference of the installation sleeve 72. The end of the support rod 73 away from the installation sleeve 72 is slidably matched with the support slide rail 71.

[0051] The pressing plate 51 is supported by the cooperation of the supporting slide rail 71 and the supporting rod 73, so that the pressing plate 51 can only slide up and down in the tank body 1, improving the stability of the pressing plate 51 during movement.

[0052] Referring to Figure 2 , Figure 3 , Figure 5 , the adjusting assembly 4 includes: a second driving member 41, a screw rod 42, and an adjusting ring 43. The second driving member 41 is arranged in the tank body 1, and the output end of the second driving member 41 is connected to the screw rod 42. The second driving member 41 is set as a motor. The screw rod 42 is arranged parallel to the central axis of the tank body 1. The adjusting ring 43 is slidably assembled up and down in the tank body 1. The adjusting ring 43 is located in the collection chamber 11, and the outer side of the adjusting ring 43 is in sliding contact with the inner side of the tank body 1. The screw rod 42 passes through the adjusting ring 43 and is in threaded cooperation with the adjusting ring 43.

[0053] Referring to Figure 5 , a first retaining ring 431 is arranged at the bottom of the adjusting ring 43. The first retaining ring 431 is located inside the adjusting ring 43, and the inner side of the first retaining ring 431 is in sliding contact with the outer side of the sliding part 32. A second retaining ring 321 is arranged on the outer side of the sliding part 32. The second retaining ring 321 is arranged below the first retaining ring 431. The sliding part 32 is sleeved outside the fixed part 31. An assembly ring 322 is arranged at the lower end of the sliding part 32. The assembly ring 322 is located below the second retaining ring 321. An elastic telescopic rod 323 is arranged at the bottom of the assembly ring 322. The elastic telescopic rod 323 is formed by two tubes with different diameters slidingly cooperating with each other, and a spring is arranged inside it. The bottom of the elastic telescopic rod 323 is fixedly connected to the tank body 1. The elastic telescopic rod 323 is used to drive the sliding part 32 to move upward.

[0054] The second driving member 41 drives the screw rod 42 to rotate. The screw rod 42 drives the adjusting ring 43 to move downward. The adjusting ring 43 drives the first retaining ring 431 and the baffle plate to cooperate, and drives the sliding part 32 to move downward through the second retaining ring 321, thereby adjusting the position of the sliding part 32. As the softened water continues to flow, every time the clogging layer needs to be cleaned, the sliding part 32 is moved downward, and after each cleaning, the sliding part 32 is fixed at the corresponding position. In addition, an elastic telescopic rod 323 is provided. During backwashing, the second driving member 41 drives the adjusting ring 43 to move upward, and the elastic telescopic rod 323 drives the sliding part 32 to move upward to the initial position, so that the resin after flushing can enter the sliding part 32 again.

[0055] Referring to Figure 1, the backwashing assembly 2 includes: a salt tank 21 filled with brine, a water inlet pipe 22 and a water outlet pipe 23 provided on the salt tank 21. Both the water inlet pipe 22 and the water outlet pipe 23 are communicated with the salt tank 21. Correspondingly, a water pump is provided on the salt tank 21, and the water pump is connected to the water inlet pipe 22 and the water outlet pipe 23 to introduce the brine into the tank body 1 and pump it out. The water inlet pipe 22 is communicated with the bottom of the tank body 1, and the water outlet pipe 23 passes through the tank body 1 and is communicated with the inside of the mounting ring 7.

[0056] Refer to Figure 1 , Figure 2 , Figure 3 , a hard water pipe 8 is provided on the tank body 1. The water outlet end of the hard water pipe 8 passes through the tank body 1 and is arranged above the mounting ring 7. A plurality of spray heads 81 are provided at the water outlet end of the hard water pipe 8. The plurality of spray heads 81 are evenly distributed above the mounting ring 7 to evenly spray the hard water onto the resin. The water outlet end of the hard water pipe 8 is arranged above the water outlet pipe 23.

[0057] When backwashing the resin is needed, the brine in the salt tank 21 is introduced into the inside of the tank body 1 through the water inlet pipe 22. The brine flows upward through the bottom of the tank body 1, passes through the resin to regenerate the resin, and finally is discharged through the water outlet pipe 23.

[0058] An auxiliary plate 9 is slidably assembled up and down in the fixing part 31. The outer side of the auxiliary plate 9 is in sliding contact with the inner side of the fixing part 31. The auxiliary plate 9 is arranged near the upper part of the fixing part 31. A plurality of auxiliary holes are opened on the auxiliary plate 9. The auxiliary holes have the same function as the through holes to allow the hard water to pass through. A second threaded groove 62 is opened on the control rod 531. The control rod 531 is in threaded cooperation with the auxiliary plate 9 through the second threaded groove 62. That is, when the control rod 531 rotates, the position of the auxiliary plate 9 can be adjusted.

[0059] Refer to Figure 2 , Figure 3 , Figure 4 , the auxiliary plate 9 presses the resin in the fixing part 31, and the pressing plate 51 presses the resin in the sliding part 32. During backwashing, the control rod 531 rotates, driving the pressing plate 51 to move upward and separate from the sliding part 32, driving the auxiliary plate 9 to move upward, relieving the pressure on the resin in the fixing part 31, so that the resin in the fixing part 31 and the sliding part 32 are both in a loose state, increasing the gap between the resins, so that during backwashing, the contact area between the brine and the resin can be increased, enabling the brine and the resin to be in full contact, and improving the regeneration treatment effect of the resin.

[0060] Refer to Figure 7 , Figure 8 , Figure 9, an annular groove 63 and an annular groove 64 are coaxially formed on the outer side of the control rod 531. The annular groove 63 communicates with the first threaded groove 61, and the annular groove 64 communicates with the second threaded groove 62. The annular groove 63 is located at the upper end of the first threaded groove 61. There are two annular grooves 64, and the two annular grooves 64 are respectively located at the upper and lower ends of the second threaded groove 62.

[0061] When the control rod 531 rotates, the intermediate ring 535 moves up and down under the action of the first threaded groove 61, and the auxiliary plate 9 moves up and down under the action of the second threaded groove 62. When the intermediate ring 535 moves to the annular groove 63, the intermediate ring 535 cooperates with the annular groove 63. At this time, when the control rod 531 rotates, the intermediate ring 535 stops moving. When the auxiliary plate 9 moves to the second threaded groove 62, the control rod 531 continues to rotate and the auxiliary plate 9 stops moving.

[0062] In the initial state, the auxiliary plate 9 cooperates with the annular groove 64 below the second threaded groove 62. When the control rod 531 rotates to drive the intermediate ring 535 to move downward and drive the sliding part 32 to move downward, the auxiliary plate 9 remains stationary and presses the resin in the fixed part 31. When backwashing the resin, the control rod 531 rotates in the reverse direction, driving the sliding part 32 to move upward. At the same time, the auxiliary plate 9 moves to cooperate with the second threaded groove 62, driving the auxiliary plate 9 to also move upward. After the auxiliary plate 9 moves a certain distance, the auxiliary plate 9 cooperates with the annular groove 64 at the upper end of the second threaded groove 62, and the auxiliary plate 9 stops moving. When the intermediate ring 535 moves to the annular groove 63, the pressing plate 51 also stops moving, so as to quickly adjust the auxiliary plate 9 and the pressing plate 51 to the specified positions.

[0063] Refer to Figure 7 , when the control rod 531 rotates in the reverse direction, the auxiliary plate 9 can move upward to cooperate with the second threaded groove 62. An auxiliary sleeve 91 is arranged in the auxiliary plate 9. The auxiliary sleeve 91 is sleeved outside the control rod 531. A connecting plate 92 and a second elastic member 93 are arranged in the auxiliary sleeve 91. The connecting plate 92 is slidably assembled up and down in the auxiliary sleeve 91. The connecting plate 92 cooperates with the second threaded groove 62 and the annular groove 64, that is, the auxiliary plate 9 moves up and down outside the control rod 531 through the connecting plate 92. The second elastic member 93 is arranged as a spring. The second elastic member 93 is respectively connected to the connecting plate 92 and the auxiliary sleeve 91. The second elastic member 93 is used to drive the connecting plate 92 to move upward.

[0064] Initially, the connecting plate 92 cooperates with the annular groove 64 at the bottom of the second threaded groove 62. At this time, when the control rod 531 rotates to drive the pressing plate 51 to move downward, the connecting plate 92 always cooperates with the annular groove 64. When the control rod 531 rotates in the reverse direction, the second elastic member 93 drives the connecting plate to cooperate with the second threaded groove 62, so as to drive the connecting plate 92 to move upward under the action of the second threaded groove 62 and adjust the position of the auxiliary plate 9.

[0065] When it is necessary to drive the pressing plate 51 and the auxiliary plate 9 to move downward, the rotation direction of the control rod 531 is adjusted. The middle ring 535 and the connecting plate 92 move downward under the action of the gravity of the pressing plate 51 and the auxiliary plate 9, so that the middle ring 535 is engaged with the first thread groove 61, and the connecting plate 92 is engaged with the second thread groove 62, so as to drive the pressing plate 51 and the auxiliary plate 9 to move downward. After the connecting plate 92 moves into the second annular groove 64 below the second thread groove 62, it stops moving, and the middle ring 535 continues to move, and cooperates with the scraping plate 52 to clean the clogging layer on the upper surface of the resin.

[0066] During backwashing, the screw rod 42 drives the adjusting ring 43 to move upward, and the sliding part 32 moves upward to the initial position under the action of the elastic telescopic rod 323. At this time, the pressing plate 51 is still above the sliding part 32. When cleaning the clogging layer, impurities and part of the resin are cleaned above the first retaining ring 431. During backwashing, the screw rod 42 drives the adjusting ring 43 to move upward, so that the resin on the first retaining ring 431 enters the sliding part 32 again. At the same time, under the action of the backwashing water flow, the impurities are backwashed outside the tank body 1, and at the same time, the resin in the collecting cavity 11 is transferred to the sliding part 32 again, so as to soften the hard water again after backwashing.

[0067] Refer to Figure 3 , a guiding inclined surface 432 is provided above the first retaining ring 431, and the side of the guiding inclined surface 432 close to the sliding part 32 slopes downward. So that during backwashing, the resin in the collecting cavity 11 enters the sliding part 32 under the action of the guiding inclined surface 432.

[0068] The implementation principle of the present invention is as follows: when it is necessary to clean the clogging on the upper surface of the resin during the treatment of hard water, the driving member two 41 drives the adjusting ring 43 to move downward through the screw rod 42, and the adjusting ring 43 drives the sliding part 32 to move downward through the first retaining ring 431 and the second retaining ring 321, so that the upper end of the sliding part 32 moves below the clogging layer. The driving member one 532 drives the scraping plate 52 to rotate through the control rod 531, and scrapes the clogging layer above the resin into the collecting cavity 11. When the control rod 531 drives the scraping plate 52 to rotate, it drives the middle ring 535 to move downward, the pressing plate 51 abuts against the upper surface of the resin, the middle ring 535 moves relative to the pressing plate 51 and compresses the first elasticity. After the scraping plate 52 scrapes off the upper layer of the resin, the pressing plate 51 moves downward under the action of the first elastic member 536, so that the pressing plate 51 cooperates with the sliding part 32 again. Repeat the above operations to repeatedly clean the clogging layer, so that the hard water and the resin are in full contact, improving the treatment efficiency.

Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
