Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical manufacturing slurry preparation process, and in particular to a slurry preparation pot with an added dual-shaft stirring system. Background Technology

[0002] The existing coating process preparation pot is a core piece of equipment in the pharmaceutical manufacturing industry used to prepare coating slurries, and its design and function directly affect the coating quality. The mainstream design of the coating process preparation pot is water chestnut-shaped or lotus-pod-shaped, with a typical tilt angle of 30–45°. Its working principle is to ensure that the slurry makes full contact with the tablet core through rotation, ensuring uniform adhesion of the coating layer.

[0003] The mixing process for pharmaceutical manufacturing involves first dissolving sucrose in water in a pot according to a specified ratio, then adding talc powder. Throughout the addition process, an anchor-type stirring paddle is used for mixing. Because the syrup formed before the addition of talc powder is slightly viscous, the talc powder floats on the surface after being poured into the pot and is difficult to dissolve. Therefore, operators must manually stir and mix the syrup using a stainless steel rod.

[0004] This operation not only has a long mixing time but also carries significant risks. It can easily cause the metal rod in the operator's hand to accidentally come into contact with the anchor-type stirring paddle in the pot, posing a great safety hazard to both personnel and machines.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a mixing pot with an added dual-shaft stirring system, which can solve the problems existing in the background technology.

[0007] To achieve the above objectives, this utility model provides a mixing pot with an added dual-shaft stirring system, comprising: a mixing pot body, the mixing pot body including a pot body, a sealing cover, and a discharge port, the sealing cover being fitted to the pot body at the connection point, and the discharge port being located at the bottom of the pot body; a stirring component, the stirring component including a central shaft stirring paddle and a side stirring paddle; and a power component, the power component including a central shaft power component and a side power component.

[0008] In one or more embodiments, the central axis impeller includes a central axis, and the side impellers include side axes; the central axis impeller is rotatable about the central axis; and the side impellers are rotatable about the side axes.

[0009] In one or more embodiments, the sealing cover includes a first through hole and a second through hole, the first through hole being used to install the central shaft agitator; the second through hole being used to install the side agitator.

[0010] In one or more embodiments, the shape of the first through hole is configured to match the shape of the central shaft, and the shape of the second through hole is configured to match the shape of the side shaft, in order to ensure a tight seal at the joint.

[0011] In one or more embodiments, the shape of the first through hole is configured to match the shape of the central axis, which is located at the center of the mixing pot body, and the side axis is configured to be offset from the center of the mixing pot body.

[0012] In one or more embodiments, the top end of the central shaft is positioned above the sealing cap; the top end of the side shaft is positioned above the sealing cap.

[0013] In one or more embodiments, the central shaft power member is mechanically connected to the top end of the central shaft; the side shaft power member is mechanically connected to the top end of the side shaft.

[0014] In one or more embodiments, the central shaft agitator further includes an anchor agitator disposed at the bottom of the central shaft; the agitator further includes blades, one or more of which are locked to the central shaft and located at the top of the anchor agitator; one or more of which are locked to the bottom of the side shaft.

[0015] Compared with the prior art, the various technical solutions and embodiments provided by this utility model include at least the following technical effects or advantages:

[0016] 1. By staggering the rotation axes of multiple agitators, the agitators can cover a larger mixing space without colliding or conflicting, while ensuring that the rotation radius coverage area does not touch.

[0017] 2. In this design, the side agitator is independent of the rotation axis of the central agitator. When the central agitator stirs the liquid at a constant speed, the non-coaxial design of the side agitator causes it to become tightly entangled with the rotation system of the central agitator, which disrupts the stable angular momentum of the liquid. This results in a chaotic flow of the liquid, a faster relative flow velocity, and allows liquids that are further apart to come into contact and mix, thus improving the mixing efficiency of the liquid.

[0021] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises", "made for", etc., shall be understood to include the stated elements or components, without excluding other elements or other components.

[0022] The purpose of this invention is to provide a mixing pot with an added dual-shaft stirring system, thereby improving mixing efficiency and reducing mechanical damage.

[0023] Example 1:

[0024] This embodiment provides a mixing pot with an added dual-shaft stirring system, characterized in that it includes: a mixing pot body, the mixing pot body including a pot body 11, a sealing cover 12, and a discharge port 13, the sealing cover 12 and the pot body 11 being fitted together in shape, and the discharge port 13 being located at the bottom of the pot body 11; a stirring component, the stirring component including a central shaft stirring paddle 21 and a side stirring paddle 22; and a power component, the power component including a central shaft power component and a side power component.

[0025] Specifically, the mixing pot is a device used in pharmaceutical manufacturing to accelerate the mixing process of materials. In order to provide a better mixing effect, this application provides a mixing pot with an added dual-shaft stirring system. The stirring components improve the stirring efficiency by cooperating with the central stirring paddle 21 and the side stirring paddle 22, solving the problem of long mixing time in the prior art. The mechanical rotation is provided by the power component, solving the problem that manual stirring by workers is prone to contact with the stirring paddle, causing mechanical damage.

[0026] In a preferred embodiment of this invention, the central axis stirring paddle 21 includes a central axis, and the side stirring paddle 22 includes a side axis; the central axis stirring paddle 21 is rotatable about the central axis; and the side stirring paddle 22 is rotatable about the side axis.

[0027] Specifically, to prevent the movement paths of the agitators from overlapping, which could lead to collisions and mechanical damage, this application sets the rotation axes of multiple agitators to be staggered. This ensures that the rotation radius coverage areas do not touch, allowing the multiple agitators to cover a larger mixing space without colliding or conflicting.

[0028] In a preferred embodiment of this invention, the sealing cover 12 includes a first through hole and a second through hole. The first through hole is used to install the central shaft stirring paddle 21, and the second through hole is used to install the side stirring paddle 22.

[0029] In a preferred embodiment of this invention, the shape of the first through hole is configured to match the shape of the central shaft, and the shape of the second through hole is configured to match the shape of the side shaft, in order to ensure a tight seal at the joint.

[0030] Specifically, the fit refers to the size of the through hole matching the thickness of the central shaft. When the mixing pot is in operation, a closed environment needs to be provided to prevent air or impurities from entering the mixing pot. Therefore, the shape fit ensures airtightness.

[0031] In a preferred embodiment of this invention, the central axis is located at the center of the mixing pot body, and the side axis is located off-center from the center of the mixing pot body.

[0032] Specifically, the biggest problem with existing mixing methods is that after the rotation speed of a single-shaft agitator stabilizes, the angular momentum of all the pharmaceutical solutions remains unchanged. In short, after the agitator has been running for a period of time, the pharmaceutical solutions rotate at a uniform speed. Macroscopically speaking, pharmaceutical solutions that are far apart lose the opportunity to come close together for mixing during the agitation process. As shown in the attached diagram, in this design, the side agitator 22 is independent of the rotation axis of the central agitator 21. When the central agitator 21 agitates the pharmaceutical solution at a uniform speed, the non-coaxial design of the side agitator 22 causes it to become tightly entangled with the rotating system of the central agitator 21, disrupting the stable angular momentum of the pharmaceutical solution. This results in a chaotic flow of the solution, an increased relative velocity, and allows more distant pharmaceutical solutions to come into contact and mix, thus improving the mixing efficiency.

[0033] In a preferred embodiment of this invention, the top end of the central shaft is positioned higher than the sealing cover 12; the top end of the side shaft is positioned higher than the sealing cover 12.

[0034] In a preferred embodiment of this invention, the central shaft power component is mechanically connected to the top end of the central shaft; the side shaft power component is mechanically connected to the top end of the side shaft.

[0035] In a preferred embodiment of this invention, the central shaft agitator 21 further includes an anchor agitator 211, which is disposed at the bottom of the central shaft; the agitator also includes blades 23, one or more of which are locked on the central shaft and located at the top of the anchor agitator 211; one or more of which are locked at the bottom of the side shaft.

[0036] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
