Description

Technical Field

[0001] This utility model relates to a compound mixing machine for processing pharmaceuticals, belonging to the field of pharmaceutical machinery technology. Background Technology

[0002] In the modern pharmaceutical industry, pharmaceutical machinery technology has entered a stage of intelligent, automated, and integrated development. While the manufacturing technology for bulk pharmaceuticals is quite advanced, many problems remain in the production and trial production of small-batch research drugs. This is especially true for drugs requiring specific production processes such as pressure, temperature, and airtightness. While large-scale production line machines can meet technical requirements, they suffer from high energy consumption, complex post-production cleaning, and disruption to normal production. Current research and production processes typically utilize equipment such as mixing tanks and small sealed reactors, but these suffer from low integration of functions. For example, they cannot adjust the speed of the mixing blades, cannot monitor the temperature and pressure of materials in real time, and the exhaust gases from the machine body pollute the research environment, creating a strong medicinal odor that is detrimental to the health of researchers. Furthermore, the machines are inconvenient to move or relocate. This solution addresses these problems by integrating existing conventional research and development processes. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the purpose of this utility model is to provide a compound mixing machine for processing pharmaceuticals, the technical solution of which is as follows:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 5 As shown, a compound mixing machine for processing pharmaceuticals includes a machine body cylinder 1, a liquid adding valve 12 provided on the machine body cylinder 1, which is used to add liquid materials into the cylinder through a connected feeding pipeline; the upper flip cover 3 is an openable structure, which is formed by the flip cover sealing handwheel 5 and the key-shaped side-opening clamping through hole 17 on the machine body cylinder 1 to form an opening and pressing sealing structure, which together constitute the feeding part;

[0028] The variable frequency motor support frame 2 is installed on the upper surface of the machine body cylinder 1. A single-phase variable frequency motor 111 is installed at the center of its upper surface. It is electrically connected to the control switch box 9 through a cable, and its running speed and running time are centrally controlled. The variable frequency motor 111 forms a material mixing device 11 through the coupling 112, main shaft 113, side scraper and bottom scraper 115.

[0029] The variable frequency motor 111 is connected to the main shaft 113 via a coupling 112. The lower end of the main shaft 113 is provided with symmetrical side scrapers 114, and the bottom of the main shaft 113 is fixedly provided with a bottom scraper 115.

[0030] The left and right symmetrical side scrapers 114 and bottom scraper 115 are perpendicular to each other. The length of the left and right symmetrical side scrapers 114 is the same as the inner diameter of the machine body cylinder 1, so as to increase the mixing and stirring effect and the scraping effect on the material adhering to the inner wall of the machine body cylinder 1.

[0031] The pressure gauge 13, installed on the upper surface of the cylinder 1, is a standard pointer-type 0-2.5 MPa pressure gauge selected according to the common micro-pharmaceutical R&D and production process, used to observe the pressure inside the cylinder. The closed safety valve 10 and the exhaust pipe 14 form a closed pressure relief section. The air discharged under overpressure is led to the upper atmosphere through the exhaust pipe 14 or led out to the attached air emission purification device to avoid polluting the R&D site environment, especially the common drug odor pollution.

[0032] A liquid level display 15 is provided on the side of the body cylinder 1. It is a high-pressure glass tube liquid level device. An electric contact liquid level device can also be selected as needed. The selection can be made according to actual needs.

[0033] A temperature sensor 16 is provided at the lower end of the liquid level display 15. The alternating signal output by the sensor is connected to the temperature control part in the control switch box 9 through a shielded cable. It is used to detect the temperature inside the body cylinder 1 and can also be used to centrally control external heating equipment as needed.

[0034] The bottom of the machine body cylinder 1 is equipped with three support feet 6 to facilitate overall balance and also to provide a certain height for the installation of the discharge valve 7 and the material discharge pipeline.

[0035] The movable casters 8 are heavy-duty metal wheels with a self-locking mechanism and solid rubber, which facilitates short-distance movement of the machine body cylinder 1 on the working surface.

[0036] Move the machine body 1 to a flat and sturdy work area, lock the support feet 6, connect the single-phase 220V AC power supply, and add the easily soluble or insoluble solid powder to be mixed and stirred by opening the upper cover 3 through the handle 4 on the upper cover 3 on the upper surface of the machine body 1. Liquid materials that can be added all at once can also be added through this feeding port. According to process requirements, liquid materials that need to be added successively can be added through the liquid adding valve 12 through the pipeline. Then close the upper cover, tighten the cover sealing handwheel 5, set the speed and working time of the variable frequency motor 111, and the mixing and stirring work can begin. At the same time, observe the parameters of the digital temperature gauge on the control switch box 9 and the pressure gauge 13 on the upper surface of the machine body 1 in order to adjust the working status of the equipment.

[0037] The variable frequency motor 111 is connected to the main shaft 113 via a coupling 112. The lower end of the main shaft 113 is provided with symmetrical side scrapers 114, and the bottom scraper 115 is fixedly provided at the bottom of the main shaft 113. The symmetrical side scrapers 114 and the bottom scraper 115 are perpendicular to each other. The length of the symmetrical side scrapers 114 is the same as the inner diameter of the machine body cylinder 1. Driven by the variable frequency motor 111, the above parts complete the mixing and stirring of the materials.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
