Description

Technical Field

[0001] This utility model belongs to the field of chemical reaction apparatus, specifically, it relates to a drug preparation, heating, stirring and mixing apparatus. Background Technology

[0002] In the mixing processes of pharmaceuticals and chemicals, the heating and stirring of high-viscosity materials has long faced three major technical bottlenecks: traditional stirring devices create dead zones in the flow field at the bottom of the tank, especially when the material viscosity is >5000 cP, the axial circulation capacity drops sharply, leading to component segregation. For example, antibiotic creams often exhibit stratification of active ingredients, affecting the consistency of efficacy; conventional jacketed heating has temperature lag, with the temperature difference between the tank core and the tank wall reaching more than 10°C. Uneven heating of biological agents can easily lead to protein denaturation, while chemical synthesis reactions may trigger local overheating side reactions; friction between the stirring scraper and the tank body generates metal debris, contaminating the material. Polytetrafluoroethylene coatings have poor wear resistance (lifespan <6 months), and the corrosion rate of stainless steel substrates in acidic environments reaches 0.5 mm / year. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a drug preparation heating and stirring mixing device to solve the problems of uneven mixing, low heat transfer efficiency and serious equipment wear.

[0004] To solve the above-mentioned technical problems, this utility model discloses a drug preparation heating and stirring mixing device, including: a reaction tank, a heating chamber arranged around the inside of the reaction tank, a heating device arranged in the heating chamber, a feed inlet at the top of the reaction tank, a metering dosing pump arranged at the feed inlet; a discharge outlet at the bottom of the reaction tank, and a stirring device arranged inside the reaction tank. The stirring device includes a stirring shaft arranged in the center of the reaction tank, and arc-shaped scrapers extending outward around the bottom of the stirring shaft and matching the contour of the bottom of the reaction tank. The gap between the outer edge of the arc-shaped scraper and the inner wall of the reaction tank is 1-5 mm. A baffle rod is arranged on the arc-shaped scraper, and a curved spiral guide plate is arranged on the upper side of the stirring shaft with a spiral angle of 45°-60°.

[0005] According to one embodiment of the present invention, the arc-shaped scraper indicates a laser-clad tungsten carbide wear-resistant layer with a thickness of 0.1-0.5 mm.

[0006] According to one embodiment of the present invention, the discharge port is provided with a filter screen.

[0007] According to one embodiment of the present invention, the heating device is a heating coil wound inside the heating chamber.

[0008] According to one embodiment of the present invention, the height of the arc-shaped scraper is one-fifth of the height of the stirring shaft.

[0009] Compared with the prior art, the present invention can achieve the following technical effects:

[0010] 1) By setting an arc-shaped scraper to work in conjunction with the bottom of the reaction tank, the material residue at the bottom is simultaneously broken up by laminar flow, eliminating sedimentation at the bottom of the reaction tank; by setting a curved spiral guide plate and a turbulence rod, a vortex is formed, which accelerates the reaction efficiency and avoids problems such as splashing.

[0016] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0017] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the active air dam at the front of a car according to an embodiment of the present invention. As shown in the figure, a drug preparation, heating, stirring and mixing device includes: a reaction tank 10, a heating chamber 20 arranged around the inside of the reaction tank 10, and a heating device 30 arranged inside the heating chamber 20.

[0018] In one embodiment of this utility model, a heating chamber 20 is arranged around the inside of the reaction vessel 10, and a heating device 30 is arranged inside the heating chamber 20. The heating device 30 is a heating coil wound inside the heating chamber 20. The heating coil makes the heating faster and more uniform, thereby improving the reaction efficiency.

[0019] Furthermore, the top of the reaction vessel 10 is provided with a feed inlet 40, and the feed inlet 40 is provided with a metering dosing pump 41; the bottom of the reaction vessel 10 is provided with a discharge outlet 50.

[0020] In detail, the reaction vessel 10 is equipped with a feed inlet 40 at the top, and a DN50 interface is provided at the feed inlet 40 to connect to a metering pump 41, so as to make the addition of reactants more precise, thereby enhancing the overall reaction rate. The reaction vessel 10 is equipped with a discharge outlet 50 at the bottom, and a filter screen is provided on the discharge outlet 50 to filter out residues and make the reactants more pure.

[0021] Preferably, the reaction vessel 10 is equipped with a stirring device 60, which includes a stirring shaft 61 located in the center of the reaction vessel 10. Around the bottom of the stirring shaft 61 are four sets of arc-shaped scrapers 70 extending outwards and matching the bottom contour of the reaction vessel 10. The outer edge of the arc-shaped scraper 70 has a gap of 1-5 mm between it and the inner wall of the reaction vessel 10. The arc-shaped scraper 70 is equipped with 44 sets of baffles 71.

[0022] In detail, a stirring device 60 is installed inside the reaction vessel 10. The stirring device 60 includes a stirring shaft 61 located in the center of the reaction vessel 10. Around the bottom of the stirring shaft 61, there are arc-shaped scrapers 70 extending outward and matching the bottom contour of the reaction vessel 10. The gap between the outer edge of the arc-shaped scraper 70 and the inner wall of the reaction vessel 10 is 1-5 mm. The arc-shaped scraper 70 is used to scrape the material at the bottom of the vessel and create radial turbulence, solving the problems of easy residue at the bottom and incomplete stirring in traditional stirring. Secondly, the height of the arc-shaped scraper 70 is one-fifth of the height of the stirring shaft 61. By setting the height of the arc-shaped scraper, the height ratio of the arc-shaped scraper 70 and the curved spiral guide plate 80 on the stirring shaft is better distributed, thereby achieving the best performance. The arc-shaped scraper 70 features a laser-clad tungsten carbide wear-resistant layer with a thickness of 0.1-0.5 mm, thereby enhancing the overall strength and wear resistance of the arc-shaped scraper 70 and extending its service life. Furthermore, the arc-shaped scraper 70 is equipped with a baffle rod 71, which enhances the stirring force of the arc-shaped scraper 70 on the bottom side of the tank and strengthens the radial turbulence effect. This allows the baffle rod 71 and the curved spiral guide plate 80 to work together to enhance the overall stirring effect of the reaction tank, improve working efficiency, and avoid the formation of dead corners for residues.

[0023] Furthermore, a curved spiral guide plate 80 is provided on the upper side of the stirring shaft 61, with a spiral angle of 45°-60°. By using the curved spiral guide plate 80 and setting its spiral angle to achieve the optimal solution, the stirring effect is enhanced to the maximum extent, the working efficiency is improved, vortices are formed to accelerate the reaction efficiency, and the purity of the reactants is higher.

[0024] In summary, this utility model achieves simultaneous bottom material residue and laminar flow crushing by setting an arc-shaped scraper 70 to cooperate with the bottom of the reaction tank 10, thus eliminating sedimentation at the bottom of the reaction tank 10; by setting a curved spiral guide plate 80 and a turbulence rod 71, a vortex is formed, which accelerates the reaction efficiency and avoids problems such as splashing.
