Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to an ion exchange mechanism for a deionized water equipment with automatic sewage discharge capability. Background Technology

[0002] The ion exchange mechanism of a deionized water system is the core component for water purification. Its core function is to adsorb cations and anions in the water through ion exchange resin, thereby reducing the water's conductivity and producing high-purity deionized water. It is typically a cylindrical pressure vessel (mostly made of stainless steel or fiberglass), filled with ion exchange resin, and is the main site of the ion exchange reaction. The specific method varies depending on the treatment process.

[0003] There are three types of ion exchange columns: cation exchange columns, filled with cation exchange resin (such as type 001×7), mainly adsorb cations (such as Na⁺, Ca²⁺, Mg²⁺, etc.) in water; anion exchange columns, filled with anion exchange resin (such as type 201×7), mainly adsorb anions (such as Cl⁻, SO₄²⁻, HCO₃⁻, etc.) in water; and mixed ion exchange columns, which are filled with both cation and anion exchange resins (mixed in a certain proportion) to further remove residual ions and improve water purity.

[0004] The ion exchange mechanism of deionized water equipment has the following defects: during operation, impurities in the raw water (such as suspended solids, colloids, unexchanged ions, etc.) will gradually accumulate, affecting the exchange efficiency. Therefore, a deionized water equipment ion exchange mechanism with automatic sewage discharge is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an ion exchange mechanism for deionized water equipment with automatic sewage discharge, which aims to improve the problem that impurities in the raw water gradually accumulate during the operation of existing ion exchange mechanisms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ion exchange mechanism for an automatically draining deionized water equipment, comprising a fixed frame and an ion exchange tank. The ion exchange tank is fixedly connected to the bottom outer wall of the fixed frame. A sludge inlet pipe is fixedly connected to the left outer wall of the ion exchange tank, and a separation pipe is fixedly connected to the right outer wall of the ion exchange tank. A sludge discharge mechanism is provided on the ion exchange tank, and an auxiliary mechanism is provided on the fixed frame. The sludge discharge mechanism includes a telescopic hydraulic cylinder, which is fixedly connected to the top inner wall of the fixed frame. A connector is fixedly connected to the output end of the telescopic hydraulic cylinder. A piston disc is threadedly connected to the side outer wall of the connector. A support column is fixedly connected to the bottom outer wall of the piston disc. An ion exchange assembly is fixedly connected to the bottom end of the support column. A separation layer assembly is fixedly connected to the bottom outer wall of the ion exchange assembly. A sealing ring is fixedly connected to the bottom outer wall of the separation layer assembly. A base plate is fixedly connected to the bottom outer wall of the sealing ring.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a T-shaped frame, the T-shaped frame is fixedly connected to the bottom outer wall of the fixed frame, a diversion chamber is slidably connected to the top outer wall of the T-shaped frame, a T-shaped groove is opened on the bottom inner wall of the diversion chamber, a collection box is in contact with the top outer wall of the diversion chamber, a filter screen is fixedly connected to the bottom inner wall of the collection box, and a drain pipe is fixedly connected to the right outer wall of the collection box.

[0008] As a further description of the above technical solution: the outer diameter of the piston disc is adapted to the inner diameter of the ion exchange tank, and the piston disc is slidably connected to the inner wall of the inner ring of the ion exchange tank.

[0009] As a further description of the above technical solution: the sealing ring contacts the bottom inner wall of the ion exchange tank, and the sealing ring contacts the bottom outer wall of the ion exchange tank.

[0010] As a further description of the above technical solution: an oleophobic layer is fixedly connected to the outer side wall of the base plate.

[0011] As a further description of the above technical solution: the T-slot is slidably connected to the top outer wall of the T-shaped frame, and a silicone pad is fixedly connected to the side outer wall of the collection box.

[0012] As a further description of the above technical solution: the filter screen is connected to the diversion chamber, and the diversion chamber is connected to the sewage pipe.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the piston disc is driven to move by the telescopic hydraulic cylinder in the sewage discharge mechanism, which can effectively scrape off the deposits on the inner wall of the ion exchange tank. At the same time, when the piston disc moves to the bottom of the tank, the ion exchange components and the separation layer components can be exposed, making it convenient for personnel to replace and maintain them. Furthermore, the separation of the sealing ring from the bottom of the tank can realize automatic sewage discharge. With the help of the diversion chamber, the collection box and the filter screen in the auxiliary mechanism, the discharged stains can be separated into solid and liquid, improving the sewage discharge effect and subsequent treatment efficiency.

[0014] 2. In this utility model, the outer diameter of the piston disc is adapted to the inner diameter of the ion exchange tank and is slidably connected, which ensures the effect of scraping off the attached substances and prevents liquid leakage; the sealing ring contacts the inner and outer walls of the bottom of the ion exchange tank, which enhances the sealing performance in the non-drainage state; the T-shaped frame and the diversion chamber are slidably connected through the T-slot, which provides stable support and sliding track for the diversion chamber; the silicone pad on the side of the collection box enhances the sealing performance between it and the diversion chamber. The overall structure is stable and reliable, which can effectively ensure the normal operation of the equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of an ion exchange mechanism for an automatically draining deionized water equipment, comprising a fixed frame 1 and an ion exchange tank 2. The ion exchange tank 2 is fixedly connected to the bottom outer wall of the fixed frame 1. An inlet pipe 3 is fixedly connected to the left outer wall of the ion exchange tank 2, and a separation pipe 32 is fixedly connected to the right outer wall of the ion exchange tank 2. The separation pipe 32 is used to discharge the pre-treated or separated liquid from the ion exchange tank 2 for subsequent treatment or discharge. A draining mechanism 4 is provided on the ion exchange tank 2, and an auxiliary mechanism 5 is provided on the fixed frame 1. The draining mechanism 4 includes a telescopic hydraulic cylinder 41, which is fixedly connected to the top inner wall of the fixed frame 1. The telescopic hydraulic cylinder 41 provides power for the operation of the draining mechanism 4, and drives other components to move through telescopic movement. A connector 42 is fixedly connected to the output end of the hydraulic cylinder 41. A piston disc 43 is threadedly connected to the outer side wall of the connector 42. A support column 44 is fixedly connected to the bottom outer wall of the piston disc 43. The support column 44 is used to connect the piston disc 43 and the ion exchange assembly 45, support the ion exchange assembly 45 and drive it to move synchronously. The bottom end of the support column 44 is fixedly connected to the ion exchange assembly 45. A separation layer assembly 46 is fixedly connected to the bottom outer wall of the ion exchange assembly 45. The separation layer assembly 46 further filters and separates the water after ion exchange, improving the water purification effect. A sealing ring 47 is fixedly connected to the bottom outer wall of the separation layer assembly 46. The sealing ring 47 plays a sealing role to prevent the liquid in the ion exchange tank 2 from leaking when not being discharged. A base plate 48 is fixedly connected to the bottom outer wall of the sealing ring 47.

[0019] Reference Figures 2-4 The outer diameter of the piston disc 43 is matched with the inner diameter of the ion exchange tank 2. The piston disc 43 is slidably connected to the inner wall of the inner ring of the ion exchange tank 2. The sealing ring 47 contacts the bottom inner wall of the ion exchange tank 2. The contact between the sealing ring 47 and the bottom inner wall of the ion exchange tank 2 enhances the sealing effect and prevents liquid leakage. The sealing ring 47 contacts the bottom outer wall of the ion exchange tank 2. An oleophobic layer is fixedly connected to the side outer wall of the bottom plate 48. The oleophobic layer can prevent oil stains from adhering to the bottom plate 48, making it easy to clean the bottom plate 48, and at the same time reducing the impact of oil stains on the sealing effect of the sealing ring 47.

[0020] Reference Figures 3-4The auxiliary mechanism 5 includes a T-shaped frame 51, which is fixedly connected to the bottom outer wall of the fixed frame 1. The T-shaped frame 51 provides an installation and support foundation for the diversion chamber 52, ensuring that the diversion chamber 52 can slide stably. The diversion chamber 52 is slidably connected to the top outer wall of the T-shaped frame 51. A T-shaped groove 53 is provided on the bottom inner wall of the diversion chamber 52. The diversion chamber 52 is used to receive the dirt discharged from the ion exchange tank 2. The sliding connection facilitates the removal and cleaning of the diversion chamber 52. The top outer wall of the diversion chamber 52... A collection box 54 is in contact with the wall. A filter screen 55 is fixedly connected to the bottom inner wall of the collection box 54. A drain pipe 56 is fixedly connected to the right outer wall of the collection box 54. A T-shaped groove 53 is slidably connected to the top outer wall of the T-shaped frame 51. A silicone pad is fixedly connected to the side outer wall of the collection box 54. The silicone pad enhances the sealing between the collection box 54 and the diversion chamber 52 to prevent liquid from leaking from the contact point between the two. The filter screen 55 is connected to the diversion chamber 52. The diversion chamber 52 is connected to the drain pipe 56.

[0021] Working principle: By opening the telescopic hydraulic cylinder 41, the connecting part 42 is moved. The movement of the connecting part 42 drives the piston disc 43 to move. The piston disc 43 moves to scrape off the deposits on the inner wall of the ion exchange tank 2. When the piston disc 43 moves to the bottom wall of the ion exchange tank 2, the internal ion exchange components 45 and separation layer components 46 are exposed to the outside for easy replacement and maintenance. At the same time, the sealing ring 47 separates from the bottom of the ion exchange tank 2, releasing the seal and allowing the internal dirt to fall onto the diversion chamber 52. Then, solid-liquid separation is performed through the filter screen 55 on the collection box 54, so that the solid dirt is collected in the collection box 54, and the separated liquid flows out from the drain pipe 56 to the outside for treatment by other equipment.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
