Abstract
Description
Technical Field
[0001] This utility model relates to the field of ion exchange column technology, specifically to an ion exchange column device. Background Technology
[0002] Currently, ion exchange columns are cylindrical pressure vessels used for ion exchange reactions, widely applied in water treatment, pharmaceuticals, food processing, biotechnology, and the nuclear industry. Their core function is to selectively adsorb or release target ions in a solution through ion exchange resin, thereby achieving the separation, purification, or removal of substances. The structure of an ion exchange column mainly consists of three parts: the first part is the column body, typically made of corrosion-resistant and pressure-resistant materials such as stainless steel, fiberglass, polyvinyl chloride, or polytetrafluoroethylene. Industrial columns often have an inner rubber lining or acid and alkali-resistant coating to extend their service life. The second part is the ion exchange resin, with resin particles packed into the column body to form a fixed or flowing resin bed. The ion exchange resin adsorbs impurities in the liquid, thus softening water, producing ultrapure water, and treating wastewater. The third part consists of auxiliary components, including inlet and outlet pipes, water distribution devices, support layers, sieve plates, and other parts. Ion exchange columns are indispensable tools in modern industry and laboratories. The problem with existing ion exchange columns is that the resin particles inside the column are densely packed, which prevents the liquid from making good contact with the resin particles. As a result, impurities in the liquid cannot be effectively removed, requiring secondary or even multiple repeated operations, which is quite troublesome.
[0003] For example, Chinese utility model patent application number CN202020068537.2, filed on January 13, 2020, describes a novel ion exchange column, including a cylindrical shell. The shell is hollow, and a resin exchange port is provided on the front side, through which ion exchange resin enters the column. Therefore, the prior art does not describe a structure that enhances the contact between the liquid and the ion exchange resin. In the prior art, the liquid does not make good contact with the resin, resulting in incomplete removal of impurities from the liquid. Utility Model Content
[0004] The purpose of this invention is to provide an ion exchange column device that can solve the problem that existing ion exchange columns do not completely remove impurities from liquids.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an ion exchange column device, comprising a cylindrical body extending vertically, a pair of outer layer plates with several holes and a pair of inner layer plates with several holes fixed on the inner wall of the cylindrical body, the pair of inner layer plates being located between the pair of outer layer plates, a main shaft penetrating the pair of inner layer plates being provided inside the cylindrical body, a stirring member located between the pair of inner layer plates and extendable when the main shaft rotates being provided outside the main shaft, and a circumferential drive member for driving the main shaft to rotate being installed on the pair of outer layer plates.
[0006] Preferably, the pore density and pore diameter on one pair of outer layers are greater than those on one pair of inner layers.
[0007] Preferably, the outer layer comprises an upper outer layer with a plurality of evenly distributed holes and a lower outer layer with a plurality of evenly distributed holes.
[0008] Preferably, the inner layer includes an upper inner plate with a plurality of evenly distributed holes and a lower inner plate with a plurality of evenly distributed holes, and resin particles are filled between the upper inner plate and the lower inner plate, wherein the diameter of the holes in the upper inner plate and the lower inner plate is smaller than the diameter of the resin particles.
[0009] Preferably, the stirring component includes multiple radial stirring columns that radially pass through the main shaft, receiving grooves opened at both ends of the radial stirring columns, telescopic columns that are slidably connected in the receiving grooves, and return springs fixed to the bottom of the receiving grooves and the tail ends of the telescopic columns.
[0010] Preferably, the circumferential drive component includes a motor fixed on the upper outer plate, a drive sleeve mounted on the motor and sleeved on the outside of the main shaft, a spline block fixed on the inner wall of the drive sleeve, and a spline groove formed on the outside of the main shaft and cooperating with the spline block.
[0011] Preferably, an axial drive component for driving the spindle to rise and fall is also installed on one of the outer outer plates. The axial drive component includes a base plate fixed to the bottom of the spindle, a plurality of hemispheres fixed in a ring array to the bottom of the base plate, and a hemispherical groove opened on the lower outer plate to accommodate the hemispheres.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) The ion exchange column device increases the contact area between the resin particles inside the ion exchange column and the liquid, so that the resin particles can remove impurities in the liquid more thoroughly, which greatly improves the working efficiency.
[0014] (2) The ion exchange column device increases the fluidity of the liquid in the resin particles inside the ion exchange column, which increases the fluidity of the liquid and the flow rate per unit time without affecting the impurity removal effect.
[0015] (3) The ion exchange column device can stir the resin particles inside the exchange column, so that the resin particles inside the ion exchange column are uniformly distributed inside the ion exchange column, thereby enhancing the removal effect of the resin particles on impurities in the liquid.

[0023] 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.
[0024] Please see Figure 1-6This utility model provides a technical solution: an ion exchange column device, comprising a cylindrical body 1 extending vertically, with a pair of outer outer plates 2 and a pair of inner plates 3 having a plurality of holes fixed on the inner wall of the cylindrical body 1. The pore density and pore diameter of the outer outer plates 2 are greater than those of the pair of inner plates 3. The pair of inner plates 3 are located between the outer outer plates 2. The outer plates 2 include an upper outer plate 2-1 with a plurality of uniformly distributed pores and a lower outer plate 2-2 with a plurality of uniformly distributed pores. The inner plates 3 include a lower outer plate 2-1 with a plurality of uniformly distributed pores and a lower outer plate 2-2 with a plurality of uniformly distributed pores. The upper inner plate 3-1 has evenly distributed holes, and the lower inner plate 3-2 has several evenly distributed holes. Resin particles are filled between the upper inner plate 3-1 and the lower inner plate 3-2. The diameter of the holes in the upper inner plate 3-1 and the lower inner plate 3-2 is smaller than the diameter of the resin particles. The cylinder 1 is provided with a main shaft 4 that penetrates a pair of inner plates 3. A stirring element 5 is provided on the outside of the main shaft 4, located between the pair of inner plates 3 and retractable when the main shaft 4 rotates. A circumferential drive element 6 that drives the main shaft 4 to rotate and an axial drive element 7 that drives the main shaft 4 to rise and fall are installed on a pair of outer plates 2.
[0025] Furthermore, the stirring component 5 includes multiple radial stirring columns 5-1 that radially pass through the main shaft 4, receiving grooves 5-2 opened at both ends of the radial stirring columns 5-1, telescopic columns 5-3 that are slidably connected in the receiving grooves 5-2, and return springs 5-4 fixed at the bottom of the receiving grooves 5-2 and the tail ends of the telescopic columns 5-3. When the main shaft 4 rotates, the telescopic columns 5-3 extend out of the receiving grooves 5-2 by centrifugal force. When the main shaft 4 stops rotating, the return springs 5-4 pull the telescopic columns 5-3 to retract back into the receiving grooves 5-2 to reset. The extension and retraction of the telescopic columns 5-3 can effectively stir the liquid and resin particles, so that the two are in full contact.
[0026] Furthermore, the circumferential drive component 6 includes a motor 6-1 fixed on the upper outer plate 2-1, a drive sleeve 6-2 mounted on the motor 6-1 and sleeved on the outside of the main shaft 4, a spline block 6-3 fixed on the inner wall of the drive sleeve 6-2, and a spline groove 6-4 opened on the outside of the main shaft 4 and cooperating with the spline block 6-3. The main shaft 4 can slide inside the drive sleeve 6-2. Through the cooperation of the spline block 6-3 and the spline groove 6-4, the main shaft 4 can be driven to rotate by the drive sleeve 6-2 while sliding.
[0027] Furthermore, the axial drive component 7 includes a base plate 7-1 fixed to the bottom of the main shaft 4, multiple hemispheres 7-2 arranged in a ring array fixed to the bottom of the base plate 7-1, and a hemispherical groove 7-3 opened on the lower outer plate 2-2 to accommodate the hemispheres 7-2. When the main shaft 4 rotates, it drives the base plate 7-1 to rotate. The rotation of the base plate 7-1 drives the hemispheres 7-2 to slide out and into the hemispherical groove 7-3 continuously, thereby driving the main shaft 4 to slide and lift.
[0028] Working Principle: Liquid flows through the holes in the outer upper plate 2-1 and the inner upper plate 3-1 into the resin particles between the inner plates 3 for impurity removal. The motor 6-1 drives the main shaft 4 to rotate intermittently through the drive sleeve 6-2. The rotation of the main shaft 4 generates centrifugal force, which causes the telescopic column 5-3 to extend. When the main shaft 4 stops rotating, the return spring 5-4 contracts and pulls the telescopic column 5-3 back to its original position. The continuous extension and retraction of the telescopic column 5-3 fully stirs the liquid and resin particles. When the main shaft 4 rotates, it also drives the hemisphere 7-2 to continuously enter and exit the hemisphere groove 7-3, so as to continuously raise and lower the main shaft 4, further enhancing the stirring effect of the telescopic column 5-3.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
