Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical production, and in particular relates to a reaction tank for pharmaceutical production. Background Art

[0002] A reaction tank is a container tank used for reaction. In the production of liquid medicines, it is often necessary to mix two or more reaction liquids together for reaction to obtain the required medicine.

[0003] In a Chinese patent with publication number CN213726434U, a reaction tank for pharmaceutical production is mentioned. Its specification discloses that the existing liquid drug reaction tank includes a tank body and a stirring device arranged in the tank body. The liquid to be reacted is added into the tank body, and the reaction liquid is stirred by the stirring device to accelerate the reaction and improve the quality of the drug. However, the current stirring device cannot fully stir the reaction liquid in the tank body. On the one hand, the stirring device cannot occupy all the space inside the tank body. The bottom and side walls of the tank body are often not accessible by the stirring device, and precipitation is easy to occur at the bottom of the tank body. On the other hand, the stirring device stirs horizontally, and the reaction liquid in the tank body is prone to upper and lower stratification. The reaction liquid convection is insufficient, which affects the reaction efficiency and drug quality.

[0004] However, the above scheme is to continuously circulate the liquid medicine by continuously extracting it out and putting it into the tank body, so that the liquid medicine cannot be fully stirred, thereby prolonging the stirring time of the liquid medicine. Utility Model Content

[0005] The utility model aims to provide a reaction tank for pharmaceutical production, so as to solve the problems in the prior art that the existing stirring device is horizontal stirring, the reaction liquid in the tank body is prone to upper and lower stratification, and the reaction liquid convection is insufficient.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A reaction tank for pharmaceutical production comprises a tank body, a first motor is installed on the end surface of the tank body, an output end of the first motor is fixedly connected to a stirring shaft, a stirring mechanism is arranged inside the tank body, the stirring mechanism comprises four fixed plates fixedly connected to the stirring shaft, a second motor is fixedly connected to the surface of the fixed plate, an output end of the second motor is fixedly connected to a circular plate, four support rods are fixedly connected to the arc surface of the circular plate, and the four support rods are fixedly connected to a circular frame at one end away from the circular plate.

[0008] Preferably, a cylinder is fixedly connected to one side of the circular plate, and a spiral sheet is fixedly connected to the arc surface of the cylinder.

[0009] Preferably, the four circular frames are distributed around the center of the circular plate, and the shape of the circular frames is hemispherical.

[0010] Preferably, a plurality of leakage holes are formed on the arc surface of the circular frame.

[0011] Preferably, an auxiliary mechanism is provided on the end surface of the tank body, and the auxiliary mechanism comprises a vertical rod fixedly connected to the end surface of the tank body, and the top end of the vertical rod is fixedly connected to a limiting frame.

[0012] Preferably, a connection frame is hingedly connected to the surface of the limiting frame, and an elastic band is fixedly connected to the surface of the connection frame.

[0013] Preferably, the cross-section of the limiting frame is L-shaped.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is provided with a circular frame and a spiral blade. When a plurality of hemispherical circular frames rotate, the liquid medicine at the bottom can be taken and transported to the upper part, which can break the stratification of the liquid medicine. Under the action of the spiral blade, the liquid medicine can be effectively stirred and mixed up and down, left and right, front and back, so as to quickly remix the stratified liquid medicine evenly, which is not conducive to the stratification of the liquid medicine. This stirring method ensures the uniform distribution of the liquid medicine components and avoids the situation of excessively high or low local concentration.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 As shown, the utility model provides a reaction tank for pharmaceutical production, including a tank body 1, a first motor 11 is installed on the end surface of the tank body 1, an output end of the first motor 11 is fixedly connected to a stirring shaft 12, a stirring mechanism 2 is arranged inside the tank body 1, the stirring mechanism 2 includes four fixed plates 21 fixedly connected to the stirring shaft 12, a second motor 22 is fixedly connected to the surface of the fixed plate 21, an output end of the second motor 22 is fixedly connected to a circular plate 23, four support rods 24 are fixedly connected to the arc surface of the circular plate 23, and a circular frame 25 is fixedly connected to one end of the four support rods 24 away from the circular plate 23.

[0024] A cylinder 26 is fixedly connected to one side of the circular plate 23 , and a spiral piece 27 is fixedly connected to the arc surface of the cylinder 26 .

[0025] In this embodiment, the spiral blades 27 can effectively stir and mix the liquid medicine up and down, left and right, and front and back, so as to quickly remix the stratified liquid medicine evenly, which is not conducive to the stratification of the liquid medicine.

[0026] The four circular frames 25 are distributed around the center of the circular plate 23, and the shape of the circular frames 25 is hemispherical. The circular arc surface of the circular frame 25 is provided with a plurality of leakage holes.

[0027] In this embodiment, the circular frame 25 serves to facilitate the transfer of the lower medicine liquid to the upper part, which is beneficial to breaking the stratification of the medicine liquid, and the leakage hole serves to facilitate the leakage of the medicine liquid in the circular frame 25.

[0028] An auxiliary mechanism 3 is provided on the end surface of the tank body 1 . The auxiliary mechanism 3 includes a vertical rod 31 fixedly connected to the end surface of the tank body 1 , and a limiting frame 32 is fixedly connected to the top of the vertical rod 31 .

[0029] A connection frame 33 is hinged on the surface of the limiting frame 32, and an elastic band 34 is fixedly connected to the surface of the connection frame 33. The cross-section of the limiting frame 32 is L-shaped.

[0030] In this embodiment, the limiting frame 32 and the connecting frame 33 serve to limit the electric wires, so as to avoid the heating of the tank body 1 during the pharmaceutical preparation process, and the electric wires are always in contact with the surface of the tank body 1, which may easily affect the electric wires. The safety is improved to a certain extent. The connecting frame 33 is hinged to adjust the angle of the electric wires, so that the electric wires can be kept away from the tank body 1.
