Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure homogenizers, in particular to an automatic sample feeding device for high-pressure homogenizers. Background Art

[0002] High-pressure homogenizer can make materials in suspension state flow at high speed through a cavity with a special internal structure under ultra-high pressure, causing a series of changes in the physical, chemical, and structural properties of the materials, ultimately achieving a homogenization effect.

[0003] The high-pressure homogenizer is composed of a sampling cup, a high-pressure homogenization chamber, a pressurizing mechanism and other components, and the sample is loaded manually. When the sample volume is large, it is necessary to manually add the sample to the sampling cup at regular intervals, which not only wastes human resources, but also easily causes sample overflow and waste if the sample is loaded too quickly. If the sample is loaded too slowly, the sampling cup is easily hollow and causes damage to the equipment. This is not what the technicians in this field expect to see. Although there are also automated sampling devices that can realize automatic sampling, most technologies use electronic equipment such as liquid level monitoring, which not only increases the cost of the equipment, but also makes the equipment more complicated and reduces reliability.

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] An automatic sampling device for a high-pressure homogenizer comprises a sample container, wherein the sample container is connected to a sampling cup of the high-pressure homogenizer through a sampling tube;

[0007] The sample injection tube is provided with a sample injection device.

[0008] Furthermore, the top cover of the sample injection cup is provided with a cup cover, and the cup cover is provided with two through holes, and the two through holes are respectively connected with the sample injection cup;

[0009] The injection tube is connected to the injection cup through one of the through holes.

[0010] Furthermore, it also includes an overflow pipe, one end of which is connected to the injection cup through another through hole, and the other end of which is connected to the sample container.

[0011] Furthermore, the sampling device is a peristaltic pump.

[0012] Furthermore, the sample container is any one of a beaker, a glass barrel, and an organic barrel.

Automatic sampling can be realized without adding electronic equipment such as liquid level detection, reducing the cost of the device and increasing the reliability of the device.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0022] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1 As shown, an automatic sampling device for a high-pressure homogenizer of the present embodiment is used to transport the sample solution from a sample container 2 containing the sample solution to a sampling cup 6 of a high-pressure homogenizer 1, and includes a sample container 2 and an overflow tube 7. The sample container 2 is connected to the sampling cup 6 of the high-pressure homogenizer 1 through a sampling tube 4; a sampling device 3 is provided on the sampling tube 4, and the sample solution in the sample container 2 is transported to the sampling cup 6 of the high-pressure homogenizer 1 through the sampling device 3, and a cup cover 5 is provided on the top cover of the sampling cup 6, and two through holes are formed on the cup cover 5, and the two through holes are respectively connected to the sampling cup 6; the sampling tube 4 is connected to the sampling cup 6 through one of the through holes; one end of the overflow tube 7 is connected to the sampling cup 6 through another through hole, and the other end of the overflow tube 7 is connected to the sample container 2.

[0025] It should be noted that the sample injection device 3 is a peristaltic pump, and the sample container 2 is any one of a beaker, a glass barrel, and an organic barrel.

[0026] Specifically, during the high-pressure homogenization process, the flow rate of the peristaltic pump is first adjusted so that the flow rate of the sampling tube 4 is slightly greater than the flow rate of the sampling of the high-pressure homogenizer 1, ensuring that the amount of sample solution in the sample cup 6 is slightly greater than the volume of the sample cup 6, and the excess sample solution will flow back to the sample container 2 through the overflow tube 7 to form a cycle, and at the same time the sample solution can enter the high-pressure homogenizer 1 to be homogenized; this structural method ensures the automatic sampling of the high-pressure homogenizer 1, which not only prevents the sample in the sampling cup 6 from running empty, but also avoids waste caused by sample overflow.

[0027] The method of using the device specifically includes the following steps:

[0028] Step 1: Clean the high pressure homogenizer according to Figure 1 Connecting pipes;

[0029] Step 2: Turn on the peristaltic pump and adjust the flow rate to a rate slightly higher than the injection rate of the high-pressure homogenizer;

[0030] Step 3: Turn on the high pressure homogenizer and collect the sample.

[0031] Step 4: Clean the high pressure homogenizer after use.

The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
