Description

Technical Field

[0001] This utility model belongs to the field of product testing and sampling tools and quality control technology, and specifically relates to an improved L-hydroxyphenylglycine central control sampler. Background Technology

[0002] L-hydroxyphenylglycine is a white crystalline solid with a molecular weight of 167.16 and is an important pharmaceutical intermediate. It is not only an important fine chemical product, but also an indispensable side-chain acid in the synthesis of broad-spectrum antibiotics such as amoxicillin, cefadroxil, cefoperazone, cefuroxime, and cefhydroxylamine.

[0003] In the production process of L-p-hydroxyphenylglycine, the quality control of intermediate products is an important part of quality assurance. The uniformity of the obtained samples directly determines the accuracy of the test results, which in turn directly affects the accurate assessment of the quality of intermediate products.

[0004] When the production process of L-p-hydroxyphenylglycine is changed to use large-package "ton bags" to hold intermediate or finished products, the requirements for central control samplers become increasingly stringent. To prevent significant quality differences among materials or intermediate products labeled as being from the same batch, or to prevent the mixing and circulation of low-content materials, it is necessary to uniformly sample and test different layers and corners of a batch or package of material to ensure that the test data is accurate, valid, and reliable, thereby providing positive guidance for production operations. Current sampling tools have problems such as not being able to perform targeted sampling at a specific point or having uneven sampling results. When sampling large packages, only the material on the upper surface can be obtained, and the sampling results cannot truly reflect the quality status of the middle and lower parts of the sampled material, resulting in weak sample representativeness. Summary of the Invention

[0005] To address the above problems and the shortcomings of existing technologies, this utility model provides an improved L-hydroxyphenylglycine central control sampler. It can accurately sample large-package intermediate products or multiple layers, multiple points, and fixed points of products in one go. It has a simple structure, saves time and effort, is safe and reliable, and has high work efficiency. At the same time, it avoids the phenomenon of sample spillage when moving the previous sampler, and has a better application effect.

[0006] This utility model discloses an improved L-hydroxyphenylglycine central control sampler, comprising: an outer tube, an outer tube handle, a sampling port, a cone, a sampling inner core, sampling slots A, B, and C, and an inner core handle. The improved L-hydroxyphenylglycine central control sampler consists of an outer tube and a sampling inner core. The outer tube surface has sampling ports of different heights, a cone at the bottom, and a handle at the top. The sampling inner core is located inside the outer tube, with a handle at its top. The lower part of the sampling inner core contains sampling slots A, B, and C of different heights. This design allows the outer tube and sampling inner core to be separated and combined, making it convenient to carry and clean, and easy to operate. The sampling slots of different heights can accurately obtain material from different or disputed locations.

[0007] Preferably, the improved L-hydroxyphenylglycine central control sampler described in this utility model is characterized in that both the outer tube and the sampling inner core are made of rigid PP or stainless steel. The outer tube has a diameter of 15-40 mm and a length of 200-1000 mm. The sampling inner core has a diameter of 14-39 mm and a length of 200-1000 mm, and the sampling inner core can rotate freely inside the outer tube. This design aims to ensure that the rigid PP tube is resistant to corrosion from acidic or alkaline materials, and that the freely rotating sampling inner core ensures accurate acquisition of materials at different heights and locations.

[0008] Preferably, the improved L-hydroxyphenylglycine central control sampler described in this utility model is characterized in that the inlet holes on the surface of the outer tube are vertically arranged, with 3 to 6 inlet holes arranged from top to bottom. This design aims to select a sampler with the appropriate number of inlet holes based on the size of the material packaging.

[0009] Preferably, the improved L-hydroxyphenylglycine central control sampler described in this utility model is characterized in that sampling slot A, sampling slot B, and sampling slot C are sequentially arranged from top to bottom in the lower middle part of the sampling core, and its shape is a hollow semi-cylinder with a sealed bottom. This design aims to enable sampling slots of different heights to sample points at different heights.

[0010] Preferably, the improved L-hydroxyphenylglycine central control sampler described in this utility model is characterized in that the sampling slots A, B, and C are spaced 100-200 mm apart. This design aims to maintain a certain distance between the sampling slots to prevent cross-contamination of materials at different heights and locations, which could lead to inaccurate sampling at specific points.

[0011] The improved L-hydroxyphenylglycine central control sampler described in this utility model has the following significant advantages: 1. It allows for free rotation of the sampling core and the setting of sampling holes at different heights, ensuring the representativeness of the sample and the reliability of the test results; 2. The sampling process is relatively closed, avoiding sample spillage and direct contact with sampling personnel, thus reducing safety risks; 3. The sampling slots A, B, and C, spaced a certain distance apart, can accurately obtain materials at different points, ensuring the authenticity of fixed-point sampling; 4. It also has the advantages of simple structure, low cost, easy manufacturing, and convenient operation. Attached Figure Description
