Description

Technical Field

[0001] The utility model relates to a liquid medicine percolation extraction system. Background Art

[0002] The percolation process of medicinal liquid is a method in which crushed medicinal materials are placed in a percolation extraction tank, solvent is continuously added from the top, and the solvent penetrates through the medicinal material layer and flows downward to leach the medicinal material components. During the percolation process, the flow rate of the solution needs to be accurately controlled, and the flow rate corresponding to each medicinal material is different; and the existing percolation extraction tanks either use a flow meter with a larger range to monitor the flow rate, or replace different flow meters when percolating different medicinal materials. For example, a pharmaceutical percolation device disclosed in announcement number CN217745814U only has a flow meter at the front end of the extraction tank to monitor the flow rate of the solution. If the flow meter with a larger range is used, the monitoring accuracy of the flow rate will be reduced. If the flow meter is replaced every time it is used, it will not only reduce the life of the pipeline but also delay production time. Utility Model Content

[0006] The outlet of the flow rate valve is connected to the liquid inlet pipe through a bend pipe, and the flow rate regulating valve is connected to the detection valve through a bend pipe.

[0007] The clean water pipe is arranged between the flow rate regulating module and the liquid inlet pipe, and the clean water pipe and the liquid inlet pipe are erected on the percolation extraction tank.

DETAILED DESCRIPTION

[0011] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0012] like Figure 1 As shown, the percolation process of different medicinal materials using the same percolation extraction tank is realized by a high-speed flow meter and a low-speed flow meter, including a percolation extraction tank 1; the top of the percolation extraction tank 1 is respectively connected to a clean water pipe 18 and a liquid inlet pipe 13, the clean water pipe and the liquid inlet pipe are respectively used to connect the percolation extraction tank 1 to the clear water river solution, and the liquid outlet valve 14 connected to the bottom controls the flow rate of the percolating medicinal solution.

[0013] like Figure 1 As shown, the liquid inlet pipe 13 is connected to the incoming liquid pipe 12 through a flow rate regulating module 15. The flow rate regulating module 15 includes a low-speed meter 8 and a high-speed meter 9. The inlets of the low-speed meter 8 and the high-speed meter 9 are respectively connected to a flow rate regulating valve to control the flow rate, thereby avoiding the problem of wasting production time by replacing the flow meter.

[0014] The liquid inlet pipe 12 is also connected to the detection valve 11, and the outlet of the monitoring valve 11 is vacant, which is used for on-site detection of the solution and for waste liquid removal when changing different solutions.

[0015] The outlet of the flow rate valve is connected to the liquid inlet pipe 13 through an elbow, and the flow rate regulating valve is connected to the detection valve 11 through an elbow. The flow rate regulating valve is connected to the confluence elbow 17 through the branch elbow 16, and the confluence elbow 17 is connected to the liquid inlet pipe 12. The elbow reduces the problem of inaccurate flow rate at the flow meter inlet caused by the accelerated flow of the solution after passing through the sharp bend congestion.

[0016] The clean water pipe 18 is arranged between the flow rate regulating module 15 and the liquid inlet pipe 13. The clean water pipe 18 and the liquid inlet pipe 13 are erected on the percolation extraction tank 1. The clean water pipe 18 and the flow rate regulating module 15 are both installed with pipe clamps 5, and all the pipe clamps 5 are connected by support rods 6. The velocity meter has a certain weight because it contains internal components, and it is not in the same vertical direction as the liquid inlet pipe 13, so the single liquid inlet pipe 13 cannot support it. Therefore, the clean water pipe is arranged between the velocity meter and the liquid inlet pipe, and the weight of the velocity meter is shared on the clean water pipe through the connecting rod, thereby reducing the support structure above the tank body.
