Foam is generated in the mixing tank. The foam is not easy to remove and the scum will also affect the appearance of the liquid medicine after it is bottled. In order to reduce the generation of foam, a liquid medicine mixing slow flow device is provided. Utility Model Content

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a mixing device according to one embodiment of the present invention; Figure 2 This is a cross-sectional schematic diagram of the flow retarder and the inner wall of the mixing tank according to one embodiment of this utility model.

[0018] A liquid mixing device includes a power chamber 2 located at the bottom inner side of an outer casing 1. A motor 3 is mounted on the left side of the power chamber 2, and a motor shaft 4 is rotatably connected to the motor 3. A reducer 5 is rotatably connected to the motor shaft 4, and a gear transmission assembly 6 is rotatably connected to the reducer 5. A mixing tank 7 is located above the power chamber 2 and is situated inside the outer casing 1. An agitator 8 is installed inside the mixing tank 7, with its lower end penetrating through the bottom of the mixing tank 7 and the top of the power chamber 2 and connected to the gear transmission assembly 6. The center point of the mixing tank 7 and the center point of the agitator 8 are on the same vertical line. The mixing tank 7 is equipped with a straight line to ensure that the stirring 8 fully mixes the medicinal liquid when it rotates. A soaking tank 11 is located at the top of the outer shell 1, and a first valve 12 is located at the bottom of the soaking tank 11. The first valve 12 is also located on the upper inner side of the outer shell 1. Two soaking tanks 11, two first valves 12, two infusion pipes 13, and two flow buffers 14 are provided. These components are symmetrical about the center point of the mixing tank 7. Different types of medicinal materials are soaked in the soaking tank 11 to extract the medicinal liquid. The bottom of the first valve 12 is connected to the infusion pipe 13, and the lower end of the infusion pipe 13 passes through the top of the mixing tank 7 and connects to the flow buffer 14. The flow buffer 14 is located on the inner walls of the left and right sides of the mixing tank 7. A medicine basket 16 is installed inside the soaking tank 11, and the surface of the medicine basket 16 has a mesh structure. The medicine soaking tank 11 is equipped with a top cover 18, and the bottom right side of the mixing tank 7 is equipped with a second valve 19, and the bottom of the second valve 19 is connected to the liquid outlet pipe 20. At the same time, the lower end of the liquid outlet pipe 20 passes through the top of the power chamber 2 and the lower front side of the outer shell 1. The liquid outlet pipe 20 is L-shaped, and the distance between the bottom of the liquid outlet pipe 20 and the bottom of the outer shell 1 is smaller than the distance between the bottom of the mixing tank 7 and the bottom of the outer shell 1, thereby increasing the liquid outlet speed.

[0019] Working principle: When using this medicine mixing device, first lift the top cover 18 upwards, and place the different types of medicinal materials into the medicine baskets 16 inside the two soaking tanks 11 respectively. Add the medicine solution medium to the two soaking tanks 11 respectively, and then reconnect the top cover 18 to the top of the soaking tanks 11. After the medicinal materials have been soaked, open the first valve 12 to allow the medicine solution in the soaking tanks 11 to flow through the first valve 12 into the infusion pipe 13, and then from the infusion pipe 13 into the flow buffer 14. The flow buffer 14 is a container with a trapezoidal vertical cross-section and an open bottom structure. When the medicine solution flows into the flow buffer 14... When the two different types of medicinal liquids have flowed into the mixing tank 7, the external power is turned on and the motor 3 is started. The motor shaft 4 drives the reducer 5 and the gear transmission group 6 to start rotating. The gear transmission group 6 drives the stirrer 8 to start rotating slowly inside the mixing tank 7, thereby mixing the medicinal liquids in the mixing tank 7. When the medicinal liquids are mixed, the external power is turned off and the second valve 19 is started, so that the mixed medicinal liquids in the mixing tank 7 can be discharged through the liquid outlet pipe 20. This completes the whole work.

[0020] The flow modulator 14 has a flow modulator box, which is hollow. The length of the flow modulator box extends along the inner wall of the mixing tank 7, and the width is wider at the top and narrower at the bottom. The upper part of the flow modulator box is connected to the infusion tube 13. The flow modulator box is fixed to the inner wall of the mixing tank 7. A guide plate 141 is provided on the upper side inside the flow modulator box. The guide plate 141 is located below the port of the infusion tube 13. The bottom of the flow modulator box is provided with a drain hole 142 arranged in a linear array along the edge of one side arc surface. The multiple drain holes 142 are inclined towards the guide groove 30 on the inner wall of the mixing tank 7. The guide groove 30 is concave.

[0021] One end of the guide plate 141 is connected to the top surface inside the slow flow box, and the other end forms a long strip-shaped liquid outlet 143 with the inclined side inside the slow flow box. The liquid outlet 143 can limit the speed of the liquid flow and drive the liquid to flow down to the bottom while adhering to the inclined side inside the slow flow box.

[0022] The bottom of the slow-flow box extends into the guide groove 30 on the inner wall of the mixing tank 7 to form a liquid outlet 144. The end of the drain hole 142 is located at the end of the liquid outlet 144. The drain hole 142 guides the liquid to the arc surface of the guide groove 30. The arc surface is used to smooth and reduce the splashing of the liquid, so that the liquid flows downward along the arc surface.

[0023] The junction between the guide channel 30 and the inner wall of the mixing tank 7 is a curved transition. The length of the guide channel 30 is equal to the length of the slow-flow box. The guide channel 30 extends along the circumference of the inner wall of the mixing tank 7. The guide channel 30 plays the role of guiding the flow of the liquid medicine, so that when the liquid medicine comes into contact with the inner wall, it reduces splashing and flows downward along the inner wall more closely.

[0024] The flow slower 14 of this invention can guide the liquid medicine to the inner wall of the mixing tank 7. The liquid medicine flows into the bottom of the tank along the inner wall of the mixing tank 7, which slows down the falling speed of the liquid medicine and reduces the impact of the liquid medicine with the bottom liquid surface, thereby reducing the generation of foam.

[0025] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
