Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of ingredient mixing tank technology, and more specifically to an ingredient mixing tank for drug production. Background Technology
[0002] Pharmaceutical mixing tanks are key pieces of equipment used in pharmaceutical manufacturing processes for mixing, stirring, and dispensing. The working principle of a pharmaceutical mixing tank is primarily based on the rotation of the stirring device, which ensures thorough and uniform mixing of the pharmaceutical raw materials and solvents within the tank. The shearing and pushing forces generated by the rotating stirring blades break down the boundaries between materials, promoting the diffusion and contact between different components, thereby achieving uniform dispensing. Simultaneously, according to process requirements, a temperature control system can heat or cool the materials to appropriate temperatures to accelerate dissolution, reaction, or prevent material deterioration.
[0003] Traditional mixing tanks typically add raw materials by weighing. This method is prone to measurement errors, which cannot effectively guarantee the therapeutic effect of the drug. Furthermore, the traditional method of adding raw materials can easily generate dust, which may further increase the measurement error between materials during mixing.
[0004] A search revealed that Chinese Patent Publication No. CN201920765674.9 discloses a batching tank for preventing material blockage; the tank includes a batching tank body, a feeding port at the top of the batching tank body, a downwardly protruding discharge port at the bottom of the batching tank body, a valve at the discharge port, and a discharge pipe with the lower end of the discharge pipe located at the discharge port and the upper end of the discharge pipe extending out of the top of the batching tank body and connected to a pneumatic pump;
[0005] In the aforementioned patent, the mixing tank for drug preparation only achieves mixing of materials through simple stirring. Therefore, when adding materials to the tank, manual weighing is required, which can lead to differences in the proportions of the materials and fail to effectively guarantee the quality of the drug, thus affecting its therapeutic effect. Utility Model Content
[0006] The purpose of this invention is to provide a mixing tank for pharmaceutical production. In this device, a feeding structure enables the feeding of multiple materials, ensuring precise proportions between them. During material addition, the tank descends to ensure that each material is added to a certain mass before transferring the drug into the tank. During drug transfer, the bottom of the tank inserts into the top of the tank, effectively reducing powder generation and ensuring proper drug proportions. Furthermore, a circulating water pipe on the outer wall of the tank provides heating to the inside, ensuring good fluidity during mixing and thus guaranteeing drug quality. This invention addresses the problems mentioned in the background section.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A pharmaceutical manufacturing ingredient tank includes a support frame; multiple feeding structures are fixedly installed on the top of the support frame; the multiple feeding structures are installed in conjunction with a storage component; the storage component includes a mounting frame; the mounting frame includes upper and lower annular plates, which are fixed together by a support rod; an ingredient tank is movably installed inside the annular plates; multiple fixing blocks are welded to the outer wall of the ingredient tank.
[0009] The fixed block and the connecting rod are movably installed; the connecting rod and the upper ring plate of the mounting frame are slidably installed; a spring is sleeved between the end of the connecting rod away from the fixed block and the upper ring plate; a flap is movably installed inside the discharge pipe at the bottom of the material tank; the flap is fixedly installed to the first inclined block through a connecting shaft;

[0011] As a further technical solution of this utility model, a second electric pusher cylinder is fixedly installed on the top of the tank by a mounting plate; the push rod of the second electric pusher cylinder is welded and fixed to the second inclined block; the second inclined block and the first inclined block are on the same plane;
[0012] As a further technical solution of this utility model, the end of the tank away from the material tank is provided with a conical surface; a rectangular discharge port is integrally provided at the bottom of the conical surface; and a stirring motor is fixedly installed on the conical surface.
[0013] As a further technical solution of this utility model, two symmetrical first electric push cylinders are also fixedly installed on the conical surface by mounting blocks; the push rod of the first electric push cylinder is movably connected to the connecting block; the connecting block is fixedly installed on the rotating shaft; the two ends of the rotating shaft are movably installed with the rectangular discharge port through semi-circular plates; the semi-circular plates are welded and fixed to the outer wall of the rectangular discharge port.
[0014] As a further technical solution of this utility model, symmetrical ear plates are fixedly installed at both ends of the rotating shaft; the ear plates are integrally formed with the baffle; the baffle is located at the bottom of the rectangular discharge port;
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In use, this utility model uses multiple feeding structures to feed the material tank, which can achieve precise feeding of various materials or specific materials. As materials are added, the material tank slides between the connecting rod and the mounting frame, compressing the spring to achieve a lowering effect until the bottom of the material tank is inserted into the top of the tank body, thus transferring the material into the tank body.
[0017] 2. In this utility model, after the bottom of the material tank is inserted into the top of the tank body, the first inclined block and the second inclined block are attached to each other. The second inclined block is driven to move forward by the second electric push cylinder, so that the first inclined block drives the flip plate to rotate synchronously through the connecting shaft, thereby transferring the material stored in the material tank into the tank body. This effectively reduces the generation of dust and thus effectively ensures the accuracy of material batching.
[0018] 3. This utility model uses a stirring motor installed at the bottom of the tank to stir the internal materials. During stirring, in order to ensure good fluidity between the materials, the heat medium is transferred through the inlet and outlet of the circulating water pipe. After stirring is completed, the first electric pusher cylinder drives the rotating shaft to rotate along the semi-circular plate through the connecting block. The two ear plates installed on the rotating shaft simultaneously drive the baffle to flip, realizing the separation of the baffle from the rectangular discharge port and achieving the discharge effect.

[0032] The fixing block 36 is movably installed with the connecting rod 32; the connecting rod 32 is slidably installed with the upper ring plate of the mounting frame 30; a spring 33 is sleeved between the end of the connecting rod 32 away from the fixing block 36 and the upper ring plate; a flap 34 is movably installed in the discharge pipe at the bottom of the material tank 31; the flap 34 is fixedly installed with the first inclined block 35 through a connecting shaft.

[0034] By adopting the above technical solution, during use, multiple feeding structures 2 are used to feed the material tank 31, which can achieve precise feeding of various materials or specific materials. As materials are added, the material tank 31 slides between the connecting rod 32 and the mounting frame 30, compressing the spring 33 to achieve a downward effect until the bottom of the material tank 31 is inserted into the top of the tank body 40, thus transferring the material into the tank body 40.
[0035] In this embodiment, a second electric pusher cylinder 48 is fixedly installed on the top of the tank body 40 by a mounting plate; the push rod of the second electric pusher cylinder 48 is welded and fixed to the second inclined block 49; the second inclined block 49 and the first inclined block 35 are on the same plane;
[0036] In this embodiment, the end of the tank 40 away from the material tank 31 is provided with a conical surface; the bottom of the conical surface is integrally provided with a rectangular discharge port; and a stirring motor 42 is fixedly installed on the conical surface.
[0037] By adopting the above technical solution, after the bottom of the material tank 31 is inserted into the top of the tank body 40, the first inclined block 35 and the second inclined block 49 are attached. The second electric push cylinder 48 drives the second inclined block 49 to move forward, so that the first inclined block 35 drives the flip plate 34 to rotate synchronously through the connecting shaft, thereby transferring the material stored in the material tank 31 into the tank body 40. This effectively reduces the generation of dust and thus effectively ensures the accuracy of material batching.

[0042] After the bottom of the material tank 31 is inserted into the top of the tank body 40, the first inclined block 35 and the second inclined block 49 are attached to each other. The second inclined block 49 is driven to move forward by the second electric push cylinder 48. The first inclined block 35 drives the flip plate 34 to rotate synchronously through the connecting shaft, thereby transferring the material stored in the material tank 31 into the tank body 40. This effectively reduces the generation of dust and ensures the accuracy of material batching.
[0043] The internal materials are stirred by the stirring motor 42 installed at the bottom of the tank 40. During stirring, in order to ensure good fluidity between the materials, the heat medium is transferred through the inlet and outlet of the circulating water pipe 41.
