Description

A mixing and stirring device for processing pharmaceutical intermediates Technical Field

[0001] This utility model relates to the technical field of pharmaceutical intermediate processing equipment, specifically a mixing and stirring device for pharmaceutical intermediate processing. Background Technology

[0002] In the processing of pharmaceutical intermediates, mixing and stirring is a crucial step. The production of pharmaceutical intermediates requires precise mixing and thorough stirring of various raw materials to ensure the uniformity and consistency of the chemical reaction, thereby improving the quality and stability of the product. However, existing mixing and stirring devices cannot filter raw materials during use, and the solid impurities contained inside may affect the purity and quality of the intermediates. In addition, the bottom of existing mixing and stirring devices is sealed, and after processing, the material needs to be poured out from the feed port, which is inconvenient to operate and may also mix in filtered impurities. To solve the above problems, a mixing and stirring device for processing pharmaceutical intermediates is needed.

[0003] Existing mixing and stirring devices for pharmaceutical intermediate processing have the problem of being unable to filter and remove impurities from raw materials and being inconvenient to discharge directly. Therefore, there is an urgent need for a mixing and stirring device for pharmaceutical intermediate processing. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a mixing and stirring device for pharmaceutical intermediate processing, so as to solve the problem that existing mixing and stirring devices for pharmaceutical intermediate processing cannot filter and remove impurities from raw materials and are not convenient for direct discharge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for processing pharmaceutical intermediates, comprising a tank, a sealing groove formed on the inner wall of the tank, a stirring motor installed at the bottom of the tank, a turntable installed at the top of the stirring motor, a stirring rod installed at the top of the turntable, a feeding sleeve installed on the inner wall of the tank, a limit spring installed on the inner wall of the feeding sleeve, a top rod installed on the outer wall of the limit spring, a sealing ring installed on the outer wall of the feeding sleeve, a positioning rod installed at the top of the feeding sleeve, a return spring installed on the outer wall of the positioning rod, a filter sleeve installed at the top of the return spring, and a positioning sleeve installed on the outer wall of the positioning rod.

[0006] Preferably, the feed sleeve is movably connected to the tank body, and the push rod forms a telescopic structure with the feed sleeve through a limiting spring.

[0007] Preferably, the push rod is symmetrically arranged around the central axis of the feeding sleeve, and the push rod is engaged with the tank body.

[0008] Preferably, the sealing ring engages with the sealing groove, and the positioning rods are arranged in a circular array with the central axis of the feed sleeve as the center.

[0009] Preferably, the filter sleeve forms a telescopic structure with a return spring and a positioning rod, and the return spring is sleeved with the positioning rod.

[0010] Preferably, the positioning rod is movably connected to the filter sleeve, and the positioning rod is threadedly connected to the positioning sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a sealing groove, a feeding sleeve, a limiting spring, a top rod, and a sealing ring. The top rod is pressed inward, and then the feeding sleeve is inserted into the tank, so that the sealing ring engages with the sealing groove. At the same time, the top rod is pushed out by the elastic force of the limiting spring, so that the top rod is engaged and fixed with the tank, which is convenient for disassembly and assembly. After the raw materials are mixed and stirred, the top rod is pressed inward, and then the feeding sleeve is pulled out, so that the material can be discharged. There is no need to pour the material out from the top of the feeding sleeve, which avoids the adhesion of filtered impurities and causes secondary pollution.

[0013] 2. This utility model, through the setting of a positioning rod, a return spring, a filter sleeve, and a positioning sleeve, allows for continuous pressing of the filter sleeve during feeding from the top of the feeding sleeve. This causes the filter sleeve to reciprocate vertically under the elastic force of the return spring, vibrating and filtering the added material. This prevents the raw materials from accumulating and clogging on the surface of the filter sleeve. At the same time, the filter sleeve ensures that the particle size of the raw materials participating in the mixing is uniform, avoiding the presence of large particles or agglomerates in the raw materials, which may cause localized uneven concentrations during the mixing process, affecting the consistency and uniformity of the reaction, and thus affecting the quality stability of the intermediate.
