Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a norfloxacin chelate layered sampling device. Background Art

[0002] Norfloxacin is also known as linoxane, norfloxacin, and its chemical name is 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazine)-3-quinolinecarboxylic acid. It is a third-generation quinolone antibacterial drug that inhibits the action of DNA gyrase of pathogenic bacteria in the digestive tract, hinders bacterial DNA replication, and has an inhibitory effect on bacteria. It is a commonly used drug for the treatment of enteritis and dysentery, but this drug has a delayed effect on bone formation in minors and will affect development.

[0003] The production of norfloxacin requires a variety of reaction catalytic synthesis and other processes, among which boron chelate is particularly important in the production of norfloxacin. When sampling the norfloxacin chelate, the norfloxacin chelate needs to be delivered to the sampling plate through a feeding pipeline.

[0004] The traditional stratified sampling device only has the function of pumping liquid, and cannot block the impurities or sediments in the liquid to be sampled, resulting in inaccurate sampling test results. Utility Model Content

The utility model solves the problem that the traditional stratified sampling device only has a liquid extraction function and cannot block impurities or precipitates in the liquid to be sampled, resulting in inaccurate sampling test results.

[0008] The liquid extraction tube is a conical structure with an upper opening larger than a lower opening, so that the liquid extraction tube can be quickly and conveniently inserted into the sealing plug of the liquid to be sampled, thereby greatly improving the sampling efficiency of the liquid extraction tube.

[0009] The aperture of the through hole at the bottom of the liquid extraction tube is larger than the aperture of the filter hole on the filter plate, so as to prevent impurities from clogging the liquid inlet of the liquid extraction tube.

[0010] A height marking line is provided on the outer side wall of the liquid extraction tube, so that the operator can more intuitively see the corresponding depth of the extracted liquid.

The utility model can filter and block impurities or sediments in the sampling liquid through the liquid suction tube 130 with a filtering function to prevent them from entering the sampling liquid to be detected, affecting the accuracy of the sampling results, and greatly reducing the efficiency of sampling detection.

[0023] According to one embodiment of the utility model, Figure 1-4As shown, a pagoda connector 140 is provided at the lower part of the connecting conduit 120. The pagoda connector 140 is used as a connector for quick connection of hydraulic oil circuits and air pressure pipelines. It is generally divided into two types: a pagoda male plug and a pagoda female plug. It is suitable for occasions with oil, water, and air as the medium. It is easy to load and unload and has reliable performance. A threaded hole is provided on the inner side wall of the lower part of the pagoda joint 140, and a fixing ring 150 is threadedly connected in the threaded hole. A filter plate 160 is provided on the upper part of the fixing ring 150, and the liquid extraction tube 130 is communicated with the lower part of the fixing ring 150. The utility model can realize the rapid disassembly of the fixing ring 150 and the blocked filter plate 160 through the threaded connection between the fixing ring 150 and the pagoda joint 140, and realize the rapid disassembly, assembly and replacement of the liquid extraction tube 130 at the same time, and the liquid extraction tube 130 can be replaced with different lengths through the detachable liquid extraction tube 130 to sample liquids of different depths, so as to facilitate the sampling and detection of liquids of various depths to be sampled.

[0024] According to another embodiment of the present invention, Figure 1 and Figure 4 As shown, the liquid extraction tube 130 is a conical structure with an upper opening larger than a lower opening. This is to facilitate the liquid extraction tube 130 to quickly and conveniently penetrate into the sealing plug of the liquid to be sampled, thereby greatly improving the sampling efficiency of the liquid extraction tube 130.

[0025] According to another embodiment of the present invention, Figure 1 and Figure 3 As shown, the aperture of the through hole at the bottom of the liquid extraction tube 130 is larger than the aperture of the filter hole on the filter plate 160 , so as to prevent impurities from clogging the liquid inlet of the liquid extraction tube 130 .

[0026] According to another embodiment of the present invention, Figure 1 and Figure 2 As shown, a height marking line is provided on the outer wall of the liquid extraction tube 130, so that the operator can more intuitively see the corresponding depth of the extracted liquid.

[0028] The use of the utility model:

[0029] First of all, it should be made clear that the sampling device involved in the utility model is mainly used for sampling and testing of liquids and flowing colloids. The utility model takes the sampling of norfloxacin chelate as an example to explain its method of use in detail. When it is necessary to sample and test liquids at different heights in a transparent container with a rubber stopper of norfloxacin chelate, a liquid extraction tube 130 of corresponding length is selected according to the depth to be sampled, and then the external thread of the fixing ring 150 of the oil drain filter plate 160 at the upper part of the liquid extraction tube 130 is threadedly connected with the internal thread of the pagoda joint 140, and then the suction port of the quantitative liquid extraction pump is connected with the upper part of the switch valve 110, and the lower part of the switch valve 110 is connected with the inner thread of the pagoda joint 140. The upper parts are connected, and then the suction tube 130 is inserted into the corresponding depth according to the depth to be sampled (the depth of the suction can be judged by the height marking line on the outer wall of the suction tube 130), and then the handle 170 is turned to open the switch valve 110, and the quantitative suction pump is started to perform sampling operations at the corresponding height. The utility model can filter and block impurities or sediments in the sampled liquid through the suction tube 130 with a filtering function to prevent them from entering the sampled liquid to be tested and affecting the accuracy of the sampling results. It solves the problem that the traditional stratified sampling device only has a suction function and cannot block impurities or sediments in the liquid to be sampled in the liquid, resulting in inaccurate sampling test results.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
