[0019] To facilitate the understanding of the present utility model, the device of the present utility model will be described more comprehensively below with reference to the relevant drawings. Embodiments of the device are shown in the drawings. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "setting" should be understood in a broad sense. For example, they can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] Embodiment

[0022] As Figures 1-3 shown, this embodiment provides a chromatography column for xylose production. The same as the traditional electric chromatography column, it includes a frame body 1, a control system 15, and a liquid cylinder 16. A stainless steel outer cylinder 2 is installed at the swing seat inside the frame body 1. A glass column body 3 is movably installed inside the stainless steel outer cylinder 2 and is limited by a limiting mechanism. Specifically, the limiting mechanism includes two limiting handles I 8 fixed to the opposite sides of the top inner wall of the stainless steel outer cylinder 2 and two limiting handles II 9 fixed to the opposite sides of the top outer surface of the glass column body 3. The limiting handle II 9 is limited in the card slot opened at the top of the limiting handle I 8. Its function is to facilitate the symmetric insertion of the glass column body 3 into the stainless steel outer cylinder 2. It should be noted that the cleaning valve 4 and the limiting handle I 8 on the right side are on the same vertical line. After the glass column body 3 is inserted into the stainless steel outer cylinder 2, it can ensure that the cleaning valve 4 and the water injection nozzle 12 are in the same position, so that the water source injected by the cleaning valve 4 can be input to the water injection nozzle 12.

[0023] An expansion cleaning airbag 11 is inlaid on the outer edge of the upper surface of the column head 10. The outer surface of the cleaning airbag 11 in a inflated state is in contact with the inner wall of the glass column body 3. The outside of the cleaning airbag 11 is also provided with protrusions distributed at equal distances, which is convenient for wiping the inner wall of the glass column body 3 when moving up and down. And the cleaning airbag 11 can be made of fluororubber material, which has good corrosion resistance and good elasticity at the same time. The cleaning airbag 11 is communicated with the inflation inner tube 6 inside the lifting lead screw 7. The top of the lifting lead screw 7 is installed with an inflation valve 5 communicated with the inflation inner tube 6, and the inflation operation of the cleaning airbag 11 is completed through external inflation equipment communicated with this.

[0024] Inside the stainless-steel outer cylinder 2, there is a pressure-boosting inner pipe 14 for boosting pressure. Specifically, the pressure-boosting inner pipe 14 is embedded in the inner wall of the stainless-steel outer cylinder 2 in an inclined spring shape, and the diameter value of the pressure-boosting inner pipe 14 gradually decreases from the input end to the output end. When water enters and is gradually conveyed, the water pressure can be increased through the decreasing diameter value. The input end of the pressure-boosting inner pipe 14 is connected to the cleaning valve 4 installed on the outer surface of the stainless-steel outer cylinder 2, and the output end of the pressure-boosting inner pipe 14 is adapted to the water injection nozzle 12 installed on the inner wall of the glass cylinder 3 (magnetically positioned through the magnetic attraction rings installed on their respective contact surfaces, and the nozzle structure is equivalent to a one-way valve to prevent the internal liquid from overflowing during the chromatography operation). An annular inner cavity 17 is provided on the inner wall of the glass cylinder 3, and several water outlet holes 13 are provided on the inner wall of the glass cylinder 3. The several water outlet holes 13 and the water injection nozzle 12 are respectively located on the inner and outer sides of the annular inner cavity. That is, the external water source is injected from the cleaning valve 4, boosted by the pressure-boosting inner pipe 14, and then input to the water injection nozzle 12 through the output end of the pressure-boosting inner pipe 14. The water source enters the annular inner cavity 17 through the water injection nozzle 12, and the water source in the annular inner cavity 17 is sprayed out through each water outlet hole 13, so as to spray and clean the inner wall of the glass cylinder 3.

[0025] It should be noted that the pressure-boosting inner pipe 14 can also be a conical spring-shaped pipe. For example, Figure 4 as shown, by gradually decreasing the diameter value of each turn of the pipe, the pressure-boosting effect can also be achieved.

[0026] In the chromatography column for xylose production described in this embodiment, when cleaning is required, the cleaning water source is injected from the cleaning valve 4, input through the pressure-boosting inner pipe 14, and input to the annular inner cavity through the water injection nozzle 12 and sprayed out from each water outlet hole 13 to clean the inner wall of the glass cylinder 3. At the same time, during the chromatography operation, the lifting lead screw 7 is operated to drive the column head 10 to move up and down, and the inflation valve 5 is inflated through an inflation device (such as an air pump). The gas enters the cleaning airbag 11 through the inflation inner pipe 6, and the cleaning airbag 11 expands and contacts the inner wall of the glass cylinder 3 to complete the brushing of the glass cylinder 3.

[0027] It should be noted that the structure described in the present invention can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other articles, is included in the protection scope of the present invention.
