[0021] The utility model will be described in more detail below in conjunction with the drawings, wherein the preferred embodiment of the utility model is shown, and it should be understood that the utility model described herein can be modified by those skilled in the art, and the advantageous effects of the utility model can still be achieved. Therefore, the following description should be understood as extensive knowledge for those skilled in the art, and not as a limitation on the utility model.

[0022] The utility model is described in more detail in the following paragraphs with reference to the drawings. The advantages and features of the utility model will be more apparent according to the following description. It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate, clear and assist the purpose of explaining the embodiment of the utility model.

[0023] As Figs. 1-2 The utility model embodiment proposes a simple and practical chromatography column flushing device, including pipeline 1, flow divider 2 and multiple cleaning heads 3.

[0024] Specifically, the liquid inlet end of the flow divider 2 is connected with the pipeline 1, the liquid outlet end of the flow divider 2 is provided with a plurality of liquid outlets, the cleaning heads 3 are arranged below the flow divider 2, and each of the cleaning heads 3 is communicated with one of the liquid outlets of the flow divider 2, for spraying cleaning liquid into the chromatographic column 4. Wherein, the plurality of liquid outlets are distributed at equal intervals, so that the cleaning liquid is uniformly distributed to each cleaning head 3, and the cleaning effect is improved.

[0025] Preferably, one end of the pipeline 1 away from the flow divider 2 is provided with a quick connector or a threaded connector, for connecting a cleaning liquid source (such as a chromatographic system and an external pump). The quick connector or the threaded connector enhances the convenience of connecting the device with the chromatographic system or the external pump.

[0026] In an embodiment, the cleaning heads 3 have a preset spacing between the liquid outlet end and the chromatographic column 4. Specifically, the preset spacing can be adjusted according to the spraying pressure of the cleaning liquid and the diameter of the chromatographic column 4. As known to those skilled in the art, the preset spacing can be set according to actual needs, and also includes other embodiments in addition to the present embodiment. The spacing setting increases the uniformity of cleaning.

[0027] In the present embodiment, the plurality of cleaning heads 3 are arranged in a linear arrangement, and the center distance between adjacent cleaning heads 3 is the spacing of a standard chromatographic column 4. Specifically, the spacing of a standard chromatographic column 4 is usually a fixed value, and the arrangement spacing of the cleaning heads 3 corresponds to it. This arrangement improves the matching degree of the cleaning device and the chromatographic column 4.

[0028] Preferably, the cleaning heads 3 are made of corrosion-resistant materials. Specifically, the corrosion-resistant materials can be selected from 316L stainless steel, polytetrafluoroethylene and other corrosion-resistant materials. As known to those skilled in the art, the selection of corrosion-resistant materials can be selected according to the type of cleaning liquid actually used. The material selection enhances the durability of the device.

[0029] In an embodiment, the present embodiment also includes a valve for controlling the cleaning heads 3 that are not aligned with the chromatographic column 4 to not discharge liquid. Specifically, one valve is arranged corresponding to each cleaning head 3, and the valve can be an electromagnetic valve or a manual valve. The control mechanism improves the use efficiency of the cleaning liquid.

[0030] In the present embodiment, the cleaning heads 3 and the liquid outlets of the flow divider 2 are detachably connected. Specifically, the detachable connection adopts threaded connection or buckle connection. The connection structure enhances the maintenance convenience of the cleaning heads 3.

[0031] In a specific example, the liquid outlet end of the cleaning head 3 is provided with a conical guide structure, and the taper angle is 30-60 degrees. As known to those skilled in the art, the taper angle can be adjusted according to the demand of cleaning effect. The guide structure improves the spraying accuracy of the cleaning liquid.

[0032] In the embodiment, the cleaning liquid enters the shunt 2 from the pipeline 1 and is then uniformly distributed to multiple liquid outlets. The cleaning liquid passes through the conical guide structure of the cleaning head 3 to form a directional jet flow, which flushes the chromatography column 4. For unused cleaning heads 3 or cleaning heads 3 without a chromatography column 4 below (or not aligned), the corresponding valve is closed to avoid waste of cleaning liquid. After use, the cleaning head 3 can be disassembled for cleaning or replacement through the detachable connection.

[0033] In summary, the chromatography column flushing device has the following advantages:

[0034] By setting the shunt and multiple cleaning heads, simultaneous cleaning of multiple chromatography columns is achieved, improving cleaning efficiency and saving labor and time costs.

[0035] By setting the valve control structure and detachable connection, the device has good adaptability and convenience, can control the liquid outlet of the cleaning head according to actual needs, avoid waste of cleaning liquid, and the cleaning head can be easily replaced and maintained, prolonging the service life of the device.

[0036] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
