Description

Technical Field

[0001] This utility model relates to the technical field of oral solution preparation, specifically a mixing device for the production of oral solutions. Background Technology

[0002] Oral liquid preparations are a type of sterile or semi-sterile oral liquid preparation made by extracting the effective components of traditional Chinese medicine decoctions, adding flavoring agents, antibacterial agents and other additives, and filling and sealing them according to the ampoule filling process of injection preparations. Therefore, they are also called oral ampoules.

[0003] The production of biological detoxifying oral liquids requires the addition of various liquid agents to achieve the desired efficacy. When these liquid solvents are placed in a mixing tank, they are usually stirred to ensure uniform mixing. However, most existing methods use a single stirring shaft, which creates a vortex that rotates in one direction, preventing the solution inside the mixing tank from being fully and evenly mixed. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the large size of the baskets, which occupy a lot of space when not in use and are inconvenient to store, this utility model provides a mixing device for the production of oral solutions.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a mixing device for the production of oral solutions, comprising a mixing tank, a tank cover installed on the top of the mixing tank, a stirring rod extending into the mixing tank body installed on the tank cover, and a scraper on the stirring rod that contacts the tank wall of the mixing tank. Multiple stirring fins are provided between the stirring rod and the scraper. A discharge pipe is provided at the bottom of the mixing tank, and a circulation pipe is provided between the discharge pipe and the upper end of the mixing tank. An annular pipe connected to the circulation pipe is provided at the upper end of the mixing tank, and multiple liquid outlet pipes are provided between the annular pipe and the upper end of the mixing tank. Multiple addition pipes are provided on the circulation pipe, each addition pipe having a one-way liquid inlet valve. The outer end of each addition pipe is connected to an external liquid supply device. A circulation pump is provided on the circulation pipe.

[0007] As a preferred embodiment of this utility model, the can lid is equipped with a drive motor that drives the stirring rod to rotate.

[0008] As a preferred embodiment of this utility model, the can lid is provided with a powder material feeding port.

[0009] As a preferred embodiment of this utility model, the discharge pipe is provided with a discharge valve.

[0010] As a preferred embodiment of this utility model, the can lid is also provided with a water inlet cleaning pipe.

[0011] As a preferred embodiment of this utility model, the bottom of the mixing tank is arched.

[0012] As a preferred embodiment of this utility model, the inner wall of the mixing tank is a smooth mirror surface and the surface is provided with an anti-corrosion coating.

[0013] The beneficial effects of this utility model are:

[0014] In this mixing device for producing oral solutions, a circulation pipe is provided between the discharge pipe and the upper end of the mixing tank, and an annular pipe connected to the circulation pipe is provided at the upper end of the mixing tank. Multiple liquid outlet pipes are provided between the annular pipe and the upper end of the mixing tank. In this way, the liquid inside the mixing tank is pumped into the annular pipe by a delivery pump and flows back to the upper layer of the solution from the liquid outlet pipe. This mixes the solution from top to bottom while stirring, thus ensuring uniform mixing. When adding additives to the mixing tank, the additives are adjusted into the circulation pipe through the addition pipe. This allows the additives to be added evenly into the oral solution as the solution circulates, and under the action of stirring, the mixture is uniformly distributed throughout.
