Description

Technical Field

[0001] This utility model belongs to the field of resin exchanger technology, specifically relating to a resin capture device for a cation exchanger. Background Technology

[0002] In many fields such as industrial water treatment, chemical production, pharmaceuticals, food and beverage, and power (especially thermal power generation), ion exchange technology is one of the core processes for water softening, desalination, and purification. Cation exchangers, as key equipment in this technology, are mainly used to remove hardness ions such as calcium and magnesium, as well as cations such as sodium and potassium, from water. Their core working medium is cation exchange resin—a porous network of high-molecular-weight polymer particles with specific chemical functional groups (such as sulfonic acid groups). During the operation of the cation exchanger (including steps such as water production, backwashing, regeneration, displacement, and forward washing), the resin bed is subjected to repeated scouring, expansion, and contraction by water flow, as well as the impact of chemical agents. This dynamic environment inevitably leads to the breakage of some resin particles due to mechanical wear, hydraulic shear, chemical aging, or thermal stress, producing fine fragments (resin fragments or powder). If these fine resin fragments flow out of the exchanger with the water flow and enter the downstream system, they will cause a series of serious problems.

[0003] However, traditional equipment cannot effectively prevent the complete containment of broken resin when intercepting it. When subjected to subsequent liquid impacts, the broken resin can still flow into downstream equipment along with the liquid flow. Furthermore, the accumulation of broken resin lacks a convenient drainage channel, requiring shutdown and disassembly for cleaning, which affects continuous production. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a resin capture device for a cation exchanger, comprising a flow cylinder, an inlet pipe connected to the inside of the flow cylinder is fixed to the outer side wall of the flow cylinder, a conical discharge cylinder is provided at one end of the flow cylinder near the inlet pipe, a metal cylinder is provided at the other end of the flow cylinder and inserted into the flow cylinder, a calibration ring plate is provided inside the flow cylinder and connected to the outer wall of the metal cylinder, a capture filter is fixed to the end face of the metal cylinder inside the flow cylinder, an assembly flange is fixed to the end face of the flow cylinder away from the inlet pipe, a positioning ring plate is fixed to the end face of the metal cylinder passing through one end of the flow cylinder and connected to the end face of the assembly flange, a plurality of limit holes are provided on the outer wall of the positioning ring plate and are evenly distributed in a ring along the circumference, and a plurality of limit rods are fixed to the end face of the assembly flange and respectively inserted into the corresponding limit holes.

[0006] The present invention further explains that an annular groove is provided on the end face of the assembly flange connected to the positioning ring plate, and a sealing ring that abuts against the end face of the positioning ring plate is bonded inside the annular groove.

[0007] This utility model further explains that the outer wall of the flow cylinder near the calibration ring plate is provided with a plurality of locking holes evenly distributed in a ring along the periphery of the flow cylinder.

[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a resin capture device for a cation exchanger, comprising a flow cylinder 1, an inlet pipe 101 connected to the inside of the flow cylinder 1 fixed to its outer side wall, a conical discharge cylinder 2 provided at one end of the flow cylinder 1 near the inlet pipe 101, and a metal cylinder 4 inserted into the flow cylinder 1 at the other end of the flow cylinder 1. A calibration ring plate 104 connected to the outer wall of the metal cylinder 4 is provided inside the flow cylinder 1. A capture filter cylinder 402 is fixed to the end face of the metal cylinder 4 inside the flow cylinder 1. An assembly flange 103 is fixed to the end face of the flow cylinder 1 away from the inlet pipe 101. A positioning ring plate 4 connected to the end face of the assembly flange 103 is fixed to the end face of the metal cylinder 4 passing through one end of the flow cylinder 1. 01. The positioning ring plate 401 has multiple sets of limiting holes 403 evenly distributed in a ring along the circumference. The end face of the assembly flange 103 is fixed with multiple limiting rods 109 respectively inserted into the corresponding limiting holes 403. The end face of the assembly flange 103 connected to the positioning ring plate 401 has an annular groove 106. The inside of the annular groove 106 is bonded with a sealing ring 107 that abuts against the end face of the positioning ring plate 401. A valve 201 is fixed at the end pipe position of the conical discharge cylinder 2. The other end of the conical discharge cylinder 2 is connected to the flow cylinder 1 through a flange seat. An observation and maintenance window 102 is fixed on the side wall of the flow cylinder 1 near the liquid inlet pipe 101. An assembly cylinder 3 is provided at the end of the positioning ring plate 401 away from the flow cylinder 1.

[0024] With the above-described structure, the metal cylinder 4 is installed in the flow cylinder 1, and the assembly cylinder 3 is installed on the metal cylinder 4. Therefore, during the operation of the cation exchanger, the resin bed is subjected to repeated scouring, expansion, contraction, and chemical impact from the water flow. This dynamic environment inevitably causes some resin particles to break due to mechanical wear, hydraulic shear, chemical aging, or thermal stress, producing fine fragments. Therefore, the liquid inlet pipe 101 on the side wall of the flow cylinder 1 is installed at the port of the cation exchanger. Thus, after the water flow carries the broken resin into the flow cylinder 1 through the liquid inlet pipe 101, the capture filter 402 used therein blocks the resin particles in the water flow, causing the resin to remain in the flow cylinder 1 outside the capture filter 402, while other liquids permeate through the capture filter 402 and flow through the inside of the metal cylinder 4 and the assembly cylinder 3. By physically intercepting and preventing the broken resin particles (fragments) from leaving the inside of the cation exchanger with the water flow, it can effectively prevent them from entering downstream pipes and equipment.

[0025] When it is necessary to clean the broken resin inside the flow cylinder 1, the valve 201 at the port of the conical discharge cylinder 2 is opened, thereby opening the conical discharge cylinder 2 and allowing the broken particles in the conical discharge cylinder 2 to be discharged.

[0026] The sealing ring 107 is located in the annular groove 106, thereby abutting against the positioning ring plate 401 and the assembly flange 103 to block the gap between them and prevent liquid leakage. The operation inside the flow cylinder 1 can be easily observed through the inspection window 102. The limiting rod 109 is inserted into the limiting hole 403, thereby positioning the positioning ring plate 401 and filtering the metal cylinder 4 and the capture filter cylinder 402.

[0027] The outer wall of the flow cylinder 1 near the calibration ring plate 104 is provided with a plurality of locking holes 105 evenly distributed in a ring around the periphery of the flow cylinder 1. The side wall of the calibration ring plate 104 is provided with screw holes 108 at the position of each set of locking holes 105. The flow cylinder 1 is screwed into the corresponding screw hole 108 by passing a bolt through the locking hole 105.

[0028] With the above-described structure, after the capture filter cartridge 402 is installed in the flow tube 1, the metal cylinder 4 and the capture filter cartridge 402 are inserted into the corresponding flow tube 1. Thus, the metal cylinder 4 will be connected to the inner side of the calibration ring plate 104. The calibration ring plate 104 calibrates and limits the metal cylinder 4, preventing the metal cylinder 4 and the capture filter cartridge 402 from shaking in the flow tube 1. The bolt is passed through the locking hole 105 and screwed into the screw hole 108 to install the calibration ring plate 104 in the flow tube 1. When the calibration ring plate 104 needs to be replaced according to the diameter of the metal cylinder 4, the bolt is turned out of the screw hole 108, so that the calibration ring plate 104 can be removed from the flow tube 1, making it easy to disassemble and replace the calibration ring plate 104.

[0029] An assembly flange 302 is fixed to the end face of the assembly cylinder 3 near the flow cylinder 1, which is connected to the end face of the positioning ring plate 401. The assembly flange 302 is connected to the assembly flange 103 through the assembly screw 304. An annular groove 303 is provided on the end face of the assembly flange 302 connected to the positioning ring plate 401. A sealing plate 305 that abuts against the end face of the positioning ring plate 401 is bonded inside the annular groove 303. A connecting flange plate 301 is fixed to the end face of the assembly cylinder 3 away from the flow cylinder 1.

[0030] With the above-described structure, the sealing plate 305 is installed in the annular groove, thereby positioning the sealing plate 305 between the assembly flange 302 and the positioning ring plate 401 to seal the gap between them.
