Technical Field

[0001] The utility model belongs to the technical field of liquid medicine processing, in particular to a centrifuge feeding device. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. The magnitude of the centrifugal force is determined by the rotation speed, rotation radius, and the melt mass of the material.

[0003] In the daily production process, manufacturers usually use centrifuges to separate the drug liquid and drug residue evenly. However, the commonly used feeding device can only feed one kind of drug liquid. When other drug liquids need to be separated, the feeding device needs to be cleaned. This method not only increases the production cost required for feeding, but also affects the production efficiency. Utility Model Content

[0006] The liquid changing mechanism includes a feed cylinder, a liquid inlet pipe, a discharge pipe and a liquid changing assembly. The feed cylinder is fixedly arranged between the liquid storage barrel and the centrifugal device. One end of the liquid inlet pipe is connected to the circulation pipe, and the other end is connected to the discharge pipe. The liquid changing assembly is arranged on the side of the liquid inlet pipe and is connected to the liquid inlet pipe.

[0013] Beneficial effects:

[0014] When it is necessary to load liquid medicine, the liquid storage tube in the liquid storage barrel needs to be filled. There are multiple liquid storage tubes, which can be used to store different liquid medicines. After the centrifuge is working, the liquid medicine is injected into the liquid exchange mechanism through the circulation tube.

DETAILED DESCRIPTION

[0018] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0019] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0020] In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0021] like Figure 1 to Figure 2 As shown, a centrifuge feeding device consists of a centrifugal device 1, a feeding barrel 2, a circulation pipe 3, a conveying pipe 4, a barrel cover 5, a liquid storage barrel 6, a liquid inlet pipe 7, a control motor 8, a rotating shaft 9, a tube changing head 10, a discharge pipe 11, and a liquid storage pipe 12.

[0022] like Figure 1 to Figure 2As shown, a centrifuge feeding device comprises a liquid storage barrel 6 and a centrifugal device 1, wherein the liquid storage barrel 6 is arranged at a designated position, and the centrifugal device 1 is connected with the liquid storage barrel 6 through a feeding assembly, wherein the feeding assembly comprises a liquid storage pipe 12 arranged in the liquid storage barrel 6, a flow pipe 3 connected with the liquid storage pipe 12, and a liquid replacement mechanism connected with the flow pipe 3;

[0023] The liquid changing mechanism includes a feed cylinder 2, a liquid inlet pipe 7, a discharge pipe 11 and a liquid changing assembly. The feed cylinder 2 is fixedly arranged between the liquid storage barrel 6 and the centrifugal device 1. One end of the liquid inlet pipe 7 is connected to the circulation pipe 3, and the other end is connected to the discharge pipe 11. The liquid changing assembly is arranged on the side of the liquid inlet pipe 7 and is connected to the liquid inlet pipe 7.

[0024] The circulation tube 3 is clamped with the feed tube 4 and the feed barrel 2. When disassembly is required, the staff can manually disassemble it from the outside. At the same time, when other liquid medicines need to be centrifuged, the position of the circulation tube 3 can be adjusted to connect with other feed tubes 4 to achieve the purpose of extracting other liquid medicines. The circulation tube 3 is easy to disassemble and can be easily removed for cleaning and maintenance.

[0025] The liquid changing assembly includes a control motor 8, a rotating shaft 9 and a tube changing head 10. The control motor 8 is fixedly installed inside the feed barrel 2. One end of the rotating shaft 9 is transmission connected to the output end of the control motor 8, and the other end is rotationally matched with the tube changing head 10.

[0026] The liquid inlet pipe is divided into two sections, and a gap is provided between the two sections of the liquid inlet pipe, and the gap is adapted to the size of the tube changing head 10.

[0027] A fixture for fixing is installed at the connection between the liquid inlet pipe and the tube changing head 10. This fixture not only includes a magnet, but can also be other connection forms for fixing the two. Each time the connection is fixed at a fixed position, when the liquid medicine is transmitted, there will be no leakage, splashing and other problems due to the unfixed position.

[0028] The gap between the liquid inlet pipe and the tube changing head 10 is the same as the longitudinal dimension of the tube changing head 10. The same size matching can reduce the gap between the two and ensure the sealing performance.

[0029] The top of the liquid storage barrel 6 is clamped with a barrel cover 5. The barrel cover 5 can prevent the liquid medicine from directly contacting pollutants in the air, thereby reducing the risk of the liquid medicine being contaminated.

[0030] The liquid storage tubes 12 are provided in plurality and are used for storing different liquid medicines.

[0031] A plurality of material delivery pipes 4 are disposed on the top of the barrel cover 5 , and the plurality of material delivery pipes 4 penetrate through the barrel cover 5 and are connected with the liquid storage pipe 12 .

[0032] The material delivery pipe 4 is clamped with the flow pipe 3 .

[0033] The working principle of this utility is as follows:

[0034] When it is necessary to load the liquid medicine, the liquid storage tube 12 in the liquid storage barrel 6 needs to be filled. There are multiple liquid storage tubes 12, which can be used to store different liquid medicines. After the centrifuge is working, the liquid medicine is injected into the liquid replacement mechanism through the circulation tube 3. The control motor 8 in the liquid replacement mechanism controls the rotation of the rotating shaft 9 to drive the tube changing head 10 to change its position. When it is necessary to centrifuge the second liquid medicine, the tube changing head 10 is replaced to avoid the problem of mixed contamination of the liquid medicines.
