Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for the regeneration liquid of a pure water instrument purification column. Background Technology

[0002] Laboratory high-purity water generators, based on reverse osmosis technology, provide a high-purity water source, ensuring the accuracy and reliability of experiments. Their workflow includes pretreatment, reverse osmosis, concentrate discharge, recirculation, and purified water storage. They play a crucial role in experimental operation, instrument protection, analytical testing, and data comparison, making them indispensable equipment in laboratories. The purification column is the core component of the high-purity water generator; its main function is to remove impurities, odors, residual chlorine, heavy metal ions, etc., from the water through the physical and chemical action of the filter media, providing high-purity, high-quality water to ensure the quality of experimental water.

[0003] In existing technologies, the resin in the purification column needs to be replaced periodically. To save costs, reverse osmosis technology is used to regenerate the resin in the purification column. This involves storing the regenerant in a storage tank and then delivering it to the purification column through a delivery pipe. After the purification column is filled with the regenerant, it is allowed to stand for a period of time. Finally, the resin in the purification column is rinsed with purified water. However, during this process of delivering the regenerant from the storage tank to the purification column, there is a lack of suitable flow control components to meet the flexible control requirements of the regeneration operation.

[0004] Therefore, this utility model proposes a purification column regeneration solution filtration device for a pure water instrument to solve the above problems. Utility Model Content

[0007] Preferably, the flow holes are arranged in three groups in the control plate, and the diameter of each group of flow holes is different, and the maximum diameter of the flow holes is equal to the diameter of the pipe opening of the conveying pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By regenerating the resin stored in the purification column, the original requirement to replace the resin in the high-purity column is replaced with regeneration, saving costs and improving economic efficiency.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a purification column regeneration liquid filtration device for a pure water instrument, including a support frame 1 and a purification column 2 disposed on the support frame 1. An inlet is provided at the top of the purification column 2, and a drain is provided at the bottom of the purification column 2. The inlet at the top of the purification column 2 is connected to one end of a delivery pipe 3, and the other end of the delivery pipe 3 is connected to a regeneration liquid storage tank 4, which is placed on the support frame 1. A connector 5 is provided on the delivery pipe 3, and a receiving cavity 6 is provided in the connector 5. The receiving cavity 6 is connected to the delivery pipe 3, and an installation groove is provided at one end of the receiving cavity 6. This solution includes a regulating component in the receiving cavity 6 to provide a regulating effect on the regeneration liquid passing through the delivery pipe 3.

[0018] According to the appendix Figure 3-4 As shown, the control component in this scheme includes a control plate 701 and flow holes 702 provided in the control plate 701. The flow holes 702 control the delivery of liquid. There are three sets of flow holes 702 in the control plate 701, and the diameter of each set of flow holes 702 is different. The maximum diameter of the flow holes 702 is equal to the diameter of the pipe opening of the delivery pipe 3. That is, by adjusting the position of the control plate 701, the flow holes 702 of different diameters can be aligned with the pipe opening of the delivery pipe 3 to control the flow of regenerated liquid and meet the needs of regenerated liquid delivery.

[0019] The control assembly also includes a control screw 704, one end of which is connected to an auxiliary bearing 703, and the auxiliary bearing 703 is fitted into one end of the connecting body 5. A control handle 706 is fixedly installed at the other end of the control screw 704. The control screw 704 is threadedly connected to the mounting plate 705, which is adapted to fit into the mounting groove at one end of the receiving cavity 6 and is fixed by screws. That is, by rotating the control screw 704 with the control handle 706, the control screw 704 pushes and pulls the control plate 701 to adjust the position of the flow hole 702.

[0020] Example 2 Based on Example 1, please refer to the appendix. Figure 4 During the position adjustment of the control plate 701, in order to ensure that the corresponding flow holes 702 on the control plate 701 can accurately reach the corresponding positions, that is, be aligned with the opening of the conveying pipe 3, this solution provides an auxiliary ring 801 on the outer ring surface of the cylindrical control handle 706, and a support strip 802 on the mounting plate 705. One end of the support strip 802 is fixedly provided with a fixing foot 803, which is fixedly connected to the mounting plate 705 by screws. Indicator pieces 804 are equidistantly arranged on the support strip 802. The indicator pieces 804 are equidistantly arranged in three sets. The indicator pieces 804 are triangular, with one of the pointed corners pointing to the control screw 704. The three sets of indicator pieces 804 correspond to the flow holes 702 in the control plate 701.

[0021] When adjusting the position of the control plate 701, as the control screw 704 rotates, when the auxiliary ring 801 located outside the control handle 706 aligns with the outermost indicator plate 804 on the support strip 802, simultaneously, the largest diameter flow hole 702 located at the front end of the control plate 701 aligns with the opening of the conveying pipe 3. This allows the operator to easily determine the position of the flow hole 702 that needs adjustment during adjustment. Similarly, when the auxiliary ring 801 outside the control handle 706 aligns with the support strip 802, the position of the flow hole 702 is adjusted. When the pointed corner of the indicator plate 804 in the middle position on the slat 802 is aligned, the flow hole 702 located in the middle position of the control plate 701 will also be aligned with the opening of the conveying pipe 3. The diameter of the flow hole 702 in the middle position of the control plate 701 is smaller than the diameter of the flow hole 702 at the front end. When the auxiliary ring 801 on the outside of the control handle 706 is aligned with the pointed corner of the indicator plate 804 on the innermost side of the support slat 802, the flow hole 702 with the smallest diameter in the control plate 701 will be aligned with the opening of the conveying pipe 3, which has good ease of operation.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
