Description

Technical Field

[0001] This invention relates to the field of resin separation, and in particular to a resin separation tower. Background Technology

[0002] Resin separation towers achieve efficient separation of anion and cation resins through hydraulic stratification. The core principle lies in utilizing differences in resin particle size, uniformity, and specific gravity, combined with specific structural design and operating procedures, to ensure effective separation. Therefore, the key to the resin separation process is precise water velocity control, which requires coordination with solenoid valves at each outlet. When the water velocity reaches a certain value, the corresponding solenoid valve in that area is opened. However, in actual use, loose wiring, short circuits, and poor plug contact can all cause solenoid valves to malfunction, leading to a failure in one solenoid valve affecting the entire separation tower's operation. Therefore, we propose a resin separation tower. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that: in existing separation towers, a large number of solenoid valves are installed at the outlet, and if one of the solenoid valves malfunctions, it will affect the resin separation operation of the entire separation tower.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a resin separation tower, comprising a tower body, and a first separation chamber and a second separation chamber arranged vertically within the inner cavity of the tower body, wherein the first separation chamber and the second separation chamber are interconnected. The inner cavity of the tower body also has a backwash hole for separating impurities, a first separation hole for separating anion resin, and a second separation hole for separating cation resin. A water inlet pipe is provided at the bottom of the second separation chamber, and an adjusting plate for controlling the backwash water speed is rotatably installed in the water inlet pipe. A sealing assembly is disposed in the backwash hole, the first separation hole, and the second separation hole to prevent water from flowing out of the tower body, including a fixing ring fixed to the tower body and a sealing umbrella member abutting against the fixing ring. A cooperating assembly is disposed inside the tower body to cooperate in controlling the opening and closing of the adjusting plate and the sealing assembly in the backwash hole, the first separation hole, and the second separation hole.

[0005] In a preferred embodiment of the resin separation tower of the present invention, the coordinating component includes a first coordinating chamber, a second coordinating chamber, and a third coordinating chamber respectively disposed in the tower body and corresponding to the backwash hole, the first separation hole, and the second separation hole. A drive motor with its output end rotatably connected to the regulating plate is fixedly installed at the bottom of the tower body.

[0006] In a preferred embodiment of the resin separation tower of the present invention, a first arc-shaped toothed block, a second arc-shaped toothed block, and a third arc-shaped toothed block are rotatably installed in the first, second, and third collaborative chambers, respectively. The first, second, and third arc-shaped toothed blocks are all engaged with collaborative racks, and a drive rod for driving the sealing assembly is fixedly installed at one end of the collaborative rack near the center of the tower body.

[0007] In a preferred embodiment of the resin separation tower of the present invention, the first arc-shaped tooth block, the second arc-shaped tooth block, and the third arc-shaped tooth block constitute a ring gear, and the second arc-shaped tooth block and the third arc-shaped tooth block have the same arc length, the arc length of the first arc-shaped tooth block is twice that of the second arc-shaped tooth block, and the third cooperating cavity is provided with a speed-changing component that is connected to the output end of the drive motor and the first arc-shaped tooth block to increase the output angle of the drive motor.

[0008] In a preferred embodiment of the resin separation tower of the present invention, the sealing umbrella has a conical cross-section, with its maximum end abutting against the fixing ring. A fixing disc is fixedly installed at the minimum end of the inner cavity of the sealing umbrella. A sliding sleeve that is fixedly connected to the tower body is coaxially fixed on the fixing disc. A sealing connecting rod with one end fixedly connected to the sealing umbrella is rotatably installed on the fixing disc and around the sliding sleeve.

[0009] In a preferred embodiment of the resin separation tower of the present invention, a control ring is slidably sleeved on the sliding sleeve, and a control link is hinged between the control ring and the sealing link, and the control ring is fixedly connected to the drive rod.

[0010] In a preferred embodiment of the resin separation tower of the present invention, the sliding sleeve has a sliding cavity and a gas cavity that are interconnected, and the sliding cavity is connected to the outside. A sealing gas ring is fixedly installed at the edge of the largest end of the sealing umbrella, and a flow pipe for communication is provided between the sealing gas ring and the gas cavity. A pushing piston is slidably installed in the gas cavity, and the pushing piston is fixedly connected to the control ring.

[0011] As a preferred embodiment of the resin separation tower of the present invention, the bottom of the tower body is provided with a resin inlet communicating with the second separation chamber, and the first separation chamber is a conical design, with the smallest end of the first separation chamber communicating with the second separation chamber.

This departs from the design of controlling the opening and closing of the traditional device through a solenoid valve. By using a mechanical structure to set the opening and closing of the backwash hole, the first separation hole, and the second separation hole together, the reliability of opening and closing is improved, the probability of failure is reduced, and the convenience of maintenance is increased. At the same time, through the conical setting of the first separation chamber, when the mixed resin enters the first separation chamber from the second separation chamber, the mixed resin will spread out, creating gaps between the resins, which facilitates the rise of anion resin and the fall of cation resin, thereby improving the resin separation efficiency.

[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of the invention.

[0019] This embodiment provides a resin separation tower, such as Figure 1 - Figure 7 As shown, the tower body 1 has a first separation chamber 11 and a second separation chamber 12 that are interconnected, as well as a backwash hole 3, a first separation hole 4 and a second separation hole 5 that are connected to the outside. The backwash hole is used to separate the flushing water containing impurities, the first separation hole 4 is used to separate the anion resin, and the second separation hole 5 is used to separate the cation resin. In addition, the bottom of the tower body 1 has a water inlet pipe 6 that is connected to the second separation chamber 12 and a resin inlet 13. At the same time, an adjusting plate 7 for adjusting the backwash water speed is also rotatably installed in the water inlet pipe 6.

[0020] Therefore, during the resin separation process, the mixed spent resin is first injected into the second separation chamber 12 through the resin inlet 13, and then backwash water is injected into the inner cavity of the tower body 1 through the water inlet 6. At this time, the water speed is the fastest. Under the impact of the backwash water, the resin layer in the second separation chamber 12 will slowly move to the first separation chamber 11. During the movement, the impurities adhering to the resin will flow out from the backwash hole 3 under the action of the water flow, achieving the effect of rinsing the resin. Then the water flow speed is slowly reduced because the particle size, uniformity and specific gravity of the cation resin are usually greater than those of the anion resin. This difference leads to different settling velocities for the two resins in the backwash water flow. When the backwash water flow rate decreases, the cation resin slowly moves to the lower part of the resin layer, while the anion resin layer remains at the upper part, completing the settling of the cation resin. Then, the water rate continues to decrease, and the anion resin layer slowly descends under its own gravity, contacting the cation resin layer and completing the anion resin settling. Next, the water rate is further reduced, and the backwash hole 3 is closed while the first separation hole 4 is opened, allowing the anion resin to flow out from the first separation hole 4. Finally, the first separation hole 4 is closed, the second separation hole 5 is opened, and the water rate is reduced, allowing the cation resin to flow out from the second separation hole 5. The mixed layer between the anion and cation resins is left for separation in the next batch. This facilitates the separation of the mixed resins.

[0021] A drive motor 94 is fixedly installed at the bottom of the tower body 1. The conveying end of the drive motor 94 is coaxially fixed with the adjusting plate 7. The tower body 1 is also provided with a first cooperating cavity 91, a second cooperating cavity 92, and a third cooperating cavity 93 corresponding to the backwashing hole, the first separation hole 4, and the second separation hole 5. A first arc-shaped toothed block 95, a second arc-shaped toothed block 96, and a third arc-shaped toothed block 97 are rotatably installed in the first cooperating cavity 91, the second cooperating cavity 92, and the third cooperating cavity 93, respectively. Block 96 and the third arc-shaped toothed block 97 are coaxially fixed, and the first arc-shaped toothed block 95, the second arc-shaped toothed block 96 and the third arc-shaped toothed block 97 are all meshed with a cooperating rack 951. The end of the cooperating rack 951 near the center of the tower body 1 is fixedly equipped with a drive rod 98 for driving the sealing assembly 8. At the same time, a speed changer 99 for increasing the output angle of the drive motor 94 is also connected in the third cooperating cavity 93. The speed changer 99 is coaxially fixed with the third arc-shaped toothed block 97 and the output end of the drive motor 94.

[0022] Therefore, when the opening and closing degree of the adjusting block is controlled by the drive motor 94, the first arc-shaped toothed block 95, the second arc-shaped toothed block 96 and the third arc-shaped toothed block 97 can be synchronously controlled by the speed change component 99 to rotate synchronously. Then, through the meshing with the cooperating rack 951, the drive rod 98 is driven to run. The operation of the sealing component 8 is driven by the transmission between the mechanical structures, so as to realize the opening and closing of the backwash hole 3, the first separation hole 4 and the second separation hole 5.

[0023] The first arc-shaped tooth block 95, the second arc-shaped tooth block 96, and the third arc-shaped tooth block 97 are combined to form a ring gear. The second arc-shaped tooth block 96 and the third arc-shaped tooth block 97 have the same arc length, and the arc length of the first arc-shaped tooth block 95 is twice that of the second arc-shaped tooth block 96. Therefore, when the first arc-shaped tooth block 95 meshes with the rack 951 to drive the sealing component 8 in the backwash hole 3 to open, the sealing components 8 in the second separation hole 5 and the first separation hole 4 are still in a closed state. When the sealing component 8 in the first separation hole 4 is opened, the sealing components 8 in the second separation hole 5 and the backwash hole 3 are in a closed state. This realizes the intermittent opening and closing between the backwash hole 3, the first separation hole 4, and the second separation hole 5. It is different from the design of controlling the opening and closing through a solenoid valve in the traditional device. The mechanical structure is used to set the opening and closing of the backwash hole 3, the first separation hole 4, and the second separation hole 5 together, which improves the reliability of opening and closing, reduces the probability of failure, and reduces the convenience of maintenance.

[0024] The sealing assembly 8 includes a fixing ring 81 fixedly connected to the tower body 1, and a sealing umbrella 82 that abuts against the fixing ring 81. A fixing disc 83 is fixedly installed on the inner side of the sealing umbrella 82. A sealing connecting rod 85 fixed to the sealing umbrella 82 is rotatably installed on the fixing disc 83. A sliding sleeve 84 fixed to the tower body 1 is fixedly installed at the center of the fixing disc 83. A control ring 86 is also slidably sleeved on the sliding sleeve 84. A control connecting rod 87 that is rotatably connected to the sealing connecting rod 85 is hinged on the control ring 86. The control ring 86 is fixedly connected to the drive rod 98. A telescopic spring fixed to the tower body 1 is wound on the drive rod 98.

[0025] When the drive rod 98 moves toward the center of the tower body 1, the drive rod 98 will drive the control ring 86 to slide on the surface of the sliding sleeve 84, and then through the rotational connection of the control link 87 and the sealing link 85, the sealing link 85 will move toward the center of the sliding sleeve 84, realizing the storage of the sealing umbrella 82 and opening the corresponding outlet to facilitate the flow of the medium inside the tower body 1. When the drive rod 98 no longer drives the control ring 86 to move, the sealing umbrella 82 will automatically unfold under the action of the telescopic spring and re-seal.

[0026] Furthermore, a sealing air ring 843 is fixedly installed at the position where the sealing umbrella component 82 abuts against the fixing ring 81. A sliding cavity 841 and an air cavity 842 are interconnected in the sliding sleeve 84. A flow pipe 844 is provided between the air cavity 842 and the sealing air ring 843 for communication. A push piston 845, which is fixedly connected to the control ring 86, is also slidably installed in the air cavity 842. Therefore, the movement of the control ring 86 will drive the push piston 845 to move in the air cavity 842, realizing the intake and exhaust of air for the sealing air ring 843, thereby achieving the effect of filling the gap between the sealing umbrella component 82 and the fixing ring 81 and improving the sealing performance of the sealing assembly 8.

[0027] Since the first separation chamber 11 is located above the second separation chamber 12, and the first separation chamber 11 has a conical design and its smallest end is connected to the second separation chamber 12, when the mixed resin enters the first separation chamber 11 from the second separation chamber 12, the mixed resin will spread out, creating gaps between the resins, which facilitates the rise of the anion resin and the fall of the cation resin, thereby improving the efficiency of resin separation.

[0028] Meanwhile, the top of the tower body 1 is also provided with an overflow port 14 corresponding to the resin inlet 13. When the sealing component 8 fails and cannot be opened, in order to prevent the resin inside the tower body 1 from being crushed by water pressure, the present invention can release the pressure of excessive backwash water through the overflow port 14, thereby achieving the effect of protecting the resin.

[0029] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
