Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material mixing, in particular to mixing equipment in the pharmaceutical industry, and specifically to a mixing device that can be assembled and separated. Background Art
[0002] In the pharmaceutical industry, mixing is a crucial step in the preparation of solid dosage forms. It not only ensures the uniform distribution of drug ingredients but also has a decisive impact on the quality and efficacy of the final product. Solid dosage forms include, but are not limited to, tablets, capsules, and granules, and mixing is a common process throughout the entire solid dosage form category.
[0003] Mixers are key equipment for achieving uniform mixing of materials and are widely used in mixing materials such as powders or granules. According to different mixing principles, mixers can be divided into mechanical mixers and gravity mixers. Mechanical mixers generate shear force through the rotation of the agitator to promote mixing between materials; while gravity mixers use the weight of the materials themselves and tilting or vibration to achieve mixing. The mixing process can generally be divided into three stages: (1) Convection mixing stage. In this stage, the materials are initially mixed through the movement of small bulk pieces, and the mixing uniformity is rapidly improved. This stage is characterized by a fast mixing speed, but there may be local unevenness problems; (2) Diffusion mixing stage. As the mixing proceeds, the mutual sliding and impact between the material particles begin to play a role, and the mixing speed becomes relatively stable. The mixing effect in this stage is more delicate, which helps to eliminate local unevenness; (3) Balanced mixing stage. Finally, the particle position exchange reaches a dynamic equilibrium state, and the mixing uniformity is kept stable or has only slight fluctuations. In this stage, the operating parameters of the mixer need to be fine-tuned to ensure the mixing quality.
[0004] In actual pharmaceutical manufacturing processes, multi-step mixing is often required to meet specific quality requirements. When the volumes of materials to be mixed in different steps vary significantly, a single mixing tank may not be able to meet the process requirements. Furthermore, material transfer between mixing tanks can result in material loss, impacting mixing efficiency and product quality.
[0005] Although existing mixing technologies can meet the needs of pharmaceutical processes in many cases, they still have limitations in handling the mixing of large and different-volume materials, reducing material loss, and improving mixing efficiency. Therefore, developing new mixing technologies or improving existing mixing equipment is of great significance for improving the preparation efficiency of solid dosage forms and reducing product loss. Utility Model Content
[0006] In view of the above-mentioned defects of the prior art, the utility model provides a mixing device that can be assembled and separated to solve the technical problems of mixing efficiency and mixing loss of materials with large volume differences.
[0007] The specific technical solutions adopted in this utility model are as follows:
[0008] A mixing device that can be assembled and separated includes a mixing device side wall, a lower closing part, and an upper closing part. The mixing device side wall and the lower closing part and the upper closing part form a closed mixing operation space; the lower closing part includes a lower closing part assembly part and a lower closing part closing piece; the upper closing part includes an upper closing part assembly part and an upper closing part closing piece.
[0009] In some specific embodiments, the lower closure assembly and the lower closure closure member are fixed by a lower fastener; and the upper closure assembly and the upper closure closure member are fixed by an upper fastener.
[0010] Furthermore, the lower closing part also includes a lower closing part elastic part, which is located between the lower closing part assembly part and the lower closing part closing part during assembly; the upper closing part also includes an upper closing part elastic part, which is located between the upper closing part assembly part and the upper closing part closing part during assembly.
[0011] In some specific embodiments, a connecting arm is fixed to the side wall of the mixing device for connecting to an external rotating device.
[0012] In some specific embodiments, there are one or more assembleable and separable mixing devices, and a plurality of the assembleable and separable mixing devices are assembled to form an integrated mixing device.
[0013] In some specific embodiments, there are two assembleable and separable mixing devices, namely a secondary mixing device and an upper mixing device. The lower closing part assembly of the upper mixing device and the upper closing part assembly of the secondary mixing device are fixed by the upper fastener of the secondary mixing device.
[0014] Furthermore, the elastic member of the upper closing part of the secondary mixing device is located between the upper closing part assembly part of the secondary mixing device and the lower closing part assembly part of the upper mixing device during assembly.
[0015] In some specific embodiments, the lower closure assembly is configured as a ridge structure, and the lower closure closure is a barrel cover; the upper closure assembly is configured as a ridge structure, and the upper closure closure is a barrel cover.
[0016] Furthermore, holes are relatively provided around the lower closure assembly part and around the lower closure part sealing member, and holes are relatively provided around the upper closure assembly part and around the upper closure part sealing member.

When the volume of the mixing device needs to be adjusted, the clamps or bolts and nuts can be loosened to disassemble the mixing device. After replacing the mixing device with the required volume, two or more mixing barrels can be assembled and fixed by clamps or bolts and nuts.
[0020] When continuous mixing is required, first pour the material into the secondary mixing unit and secure the lid to the unit with clamps or bolts and nuts to seal it. Once mixing is complete, remove the lid from the secondary unit and secure the lower portion of the upper mixing unit to the upper portion of the secondary mixing unit with clamps or bolts and nuts to form an integrated mixing unit, increasing the mixing volume.
