Description

Technical Field

[0001] The temperature - controllable ion - exchange resin column of the utility model relates to the technical field of ion exchange, and particularly to a temperature - controllable ion - exchange resin column for pharmaceutical production. Background Art

[0002] Ion - exchange technology is a commonly used technology in modern pharmaceutical production. In industrial production, various types of ion - exchange resins are filled into an ion - exchange resin column for cation and anion exchange. A conventional ion - exchange resin column consists of an upper head, a water distributor, a cylinder body, a sieve plate, a lower head, and pipes for inlet and outlet liquid.

[0003] During the ion - exchange process, the exothermic or endothermic phenomenon of the material causes the temperature of the liquid to exceed the range required by the process parameters, while the conventional ion - exchange resin column does not have the function of regulating the temperature of the liquid.

[0004] In view of the problems existing in the above - mentioned prior art, it is very necessary to research and design a new type of temperature - controllable ion - exchange resin column to overcome the problems existing in the prior art. Summary of the Invention

[0005] In view of the technical problem that the conventional ion - exchange resin column does not have the function of regulating the temperature of the liquid as proposed in the above - mentioned prior art, a temperature - controllable ion - exchange resin column is provided. The utility model mainly realizes temperature control of the ion - exchange resin column by arranging a heat exchanger in the ion - exchange resin column to conduct heat exchange on the ion - exchange resin.

[0006] The technical means adopted by the utility model are as follows:

[0007] A temperature - controllable ion - exchange resin column includes: an upper head, a water distributor, a cylinder body, a sieve plate, and a lower head; the top of the cylinder body is assembled with the upper head by bolts, and the bottom is welded to the lower head to form an ion - exchange column. After unscrewing the bolts at the top, ion - exchange resin can be added; a liquid pipe connected to the water distributor in the upper part of the cylinder body is arranged at the central position of the upper head; an outlet liquid pipe communicating with the inside of the cylinder body is arranged at the center of the lower head; a sieve plate is horizontally installed at the lower part of the cylinder body.

[0008] Further, holes are arranged on the upper head;

[0009] Further, a heat exchanger extending into the inside of the cylinder body is inserted into the holes;

[0010] Further, the heat exchanger is connected to an external cold / hot medium pipe.

[0011] Further, 6 - 12 heat exchangers are arranged.

[0012] Further, the heat exchanger has a double - spiral tube structure with a common bottom, and the two ports at the top are respectively connected to the inlets and outlets of the cold / hot medium equipment to realize the circulating flow of the cold and hot media.

[0013] Further, the bottom end of the heat exchanger is slightly higher than the upper end of the sieve plate.

[0014] Further, the heat exchanger is vertically arranged with respect to the sieve plate.

[0015] Further, filter meshes with different mesh numbers are laid on the sieve plate for carrying ion - exchange resin particles.

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] 1. For the temperature - controllable ion - exchange resin column provided by the present utility model, the heat exchanger 8 can heat or cool the feed liquid in time, and control the overall temperature of the feed liquid in the ion - exchange resin column within the process requirements, solving the problem of controlling the temperature of the feed liquid during the ion - exchange process.

[0018] 2. For the temperature - controllable ion - exchange resin column provided by the present utility model, the vertically - arranged slender cylindrical heat exchanger does not affect the working state of the ion - exchange resin. While controlling the temperature of the feed liquid, it does not increase the height of the diffusion layer, avoiding the dilution of the feed liquid.

[0019] In summary, the technical solution of the present utility model solves the problem that the conventional ion - exchange resin column in the prior art does not have the function of adjusting the temperature of the feed liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. The description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present utility model. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, steps, operations, devices, components and / or their combinations.

[0027] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be clear that, for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the authorized specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0029] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0030] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components.

[0032] The upper head 1 is connected to the top end of the cylinder body 3 by bolts. After unscrewing the bolts, the upper head 1 can be separated from the cylinder body 3, which is convenient for adding ion exchange resin. There is a hole at the central position of the upper head 1 for assembling the liquid pipe 6 connected to the water distributor 2.

[0033] The lower head 5 is connected to the lower end of the cylinder body 3. There is a hole at the central position of the upper head 5, and the hole is connected to the liquid outlet pipeline 7.

[0034] A sieve plate 4 is horizontally installed at the lower part of the cylinder body 3. The periphery of the sieve plate 4 is hermetically connected to the cylinder body 3, and holes are evenly arranged on the sieve plate. Different mesh filters can be laid on the sieve plate 4 to carry ion exchange resin particles.

[0035] Eight holes are evenly arranged around the central hole of the upper head 1 for assembling the cylindrical heat exchanger 8. The heat exchanger 8 is a double spiral tube structure with a common bottom, and the two ports at the top are respectively connected to the inlets and outlets of the cold / hot medium equipment to realize the circulating flow of the cold and hot media. The external structure of the heat exchanger 8 is an elongated cylinder, which is arranged perpendicular to the sieve plate 4.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
