Description

Technical Field

[0001] This utility model relates to the field of equipment for the production and processing of traditional Chinese medicine, and specifically to a simple device for measuring percolation flow rate. Background Technology

[0002] In the production of traditional Chinese medicine, some raw materials require percolation to extract their active ingredients. The flow rate of the percolate is a key parameter in the production process. Currently, existing percolation equipment faces challenges in controlling the flow rate.

[0003] 1. According to the working principle of percolation, the solvent continuously permeates through the raw material layer through diffusion and flows out from top to bottom by its own gravity. No other external forces, such as pressure or suction, can be applied during the process. Therefore, the flow rate is unstable throughout the percolation process.

[0004] 2. The percolation operation is located in the explosion-proof area of ​​the extraction workshop. Electronic equipment or electronic equipment equipped with explosion-proof devices shall not be used in this area.

[0005] Because of the aforementioned difficulties, current flow rate control in percolation equipment relies solely on manual adjustment of the leachate valve's opening and closing, with flow rate measured using a graduated cylinder. This method is time-consuming, labor-intensive, and inconvenient, and carries the risk of microbial contamination each time. Furthermore, the solution used for measurement cannot be returned to the collection tank, resulting in material loss.

[0006] Based on market research, the mainstream flow meters currently available are categorized as follows: differential pressure, electromagnetic, ultrasonic, turbine, vortex, volumetric, mass, and float. Considering the actual conditions of the workshop and the application scenarios, there are currently no flow meters on the market that can be used directly.

[0007] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0008] The purpose of this invention is to provide a simple device for measuring percolation flow rate, so as to overcome the above-mentioned shortcomings and deficiencies of the prior art.

[0009] A simple device for measuring percolation flow rate includes: an upper control valve, an exhaust valve, a glass tube, and a lower drain valve. One end of the upper control valve is connected to an upstream device, the other end of the upper control valve is connected to one end of the exhaust valve, the other end of the exhaust valve is connected to one end of the glass tube, the other end of the glass tube is connected to one end of the lower drain valve, and the other end of the lower drain valve is connected to a downstream device.

[0010] Furthermore, the glass tube is provided with graduations.

[0011] The beneficial effects of this utility model are:

[0012] Compared with traditional technology, this utility model is completely sealed during the measurement process, avoiding the problem of microbial contamination of the medicine solution that may occur when using a measuring cylinder in traditional technology; it will not cause loss or waste of leachate, and increases the yield of leachate; the measurement process is simple and convenient, and can quickly familiarize employees with the opening and closing range of the control valve that meets the process requirements, reducing the workload of employees.

[0014] Figure label:

[0015] Upper control valve 100, exhaust valve 200, glass tube 300 and lower drain valve 400. Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Example 1

[0018] Figure 1 This is a schematic diagram of the structure of this utility model.

[0019] like Figure 1 As shown, a simple device for measuring percolation flow rate includes: an upper control valve 100, an exhaust valve 200, a glass tube 300, and a lower drain valve 400. One end of the upper control valve 100 is connected to an upstream device, and the other end of the upper control valve 100 is connected to one end of the exhaust valve 200. The other end of the exhaust valve 200 is connected to one end of the glass tube 300, and the other end of the glass tube 300 is connected to one end of the lower drain valve 400. The other end of the lower drain valve 400 is connected to a downstream device.

[0020] The glass tube 300 has graduations.

[0021] The method of using this utility model is as follows: Step 1: Inspect the appearance of the device to ensure that all components are tightly connected and free of looseness, that the glass tube 300 is clear of foreign objects, and that all valves are closed. Step 2: Open the lower drain valve 400 to the "fully open" position, open the upper control valve 100, and adjust the opening and closing range of the control valve to control the leachate flow rate to approach the target flow rate. Step 3: Close the lower drain valve 400, open the vent valve 200, and when the liquid level in the glass tube 300 reaches the "0" mark, use a mechanical timer to time 60 seconds. Step 4: After 60 seconds, record the liquid level height in the glass tube 300. The liquid level height should be within 75-95ml (taking Guipi Heji as an example). Step 5: After reaching the required flow rate, keep the opening and closing range of the upper control valve 100 unchanged, open the lower drain valve 400, close the vent valve 200, and begin collecting the leachate. Step 6: If the liquid level scale is not in this range, the opening angle of the upper control valve 100 needs to be readjusted according to the liquid level, and steps 2, 3, 4 and 5 above are repeated until the flow rate range that meets the process requirements is reached.

[0022] The innovation of this invention lies in achieving precise flow rate measurement through a simple mechanical structure, solving the problem of not being able to use electronic equipment in explosion-proof areas. This invention creatively designs a sealed measurement system, combining the upper control valve 100, exhaust valve 200, glass tube 300, and lower drain valve 400 into a complete measurement unit. By controlling the opening and closing states of each valve, the flow rate of leachate can be measured without interrupting the flow or contacting the external environment. The physical measurement method based on timed liquid accumulation and its structural implementation solve the problems of microbial contamination risk and material loss. This invention proposes a physical measurement method based on the liquid accumulation height over a fixed time period. By precisely controlling the opening and closing states of the lower drain valve 400 and exhaust valve 200, the scale of the glass tube 300 visually displays the amount of liquid accumulated within 60 seconds. The innovation of this method lies in achieving the flow rate measurement function through the ingenious combination of timed liquid accumulation and scale readings, implemented within the mechanical structure itself. Operators only need to judge whether the flow rate meets the requirements based on simple scale readings and preset time, without the need for complex calculations. This greatly reduces the requirements for measuring equipment, transforming traditional external measuring cylinder measurements into internal pipe measurements.

[0023] Compared with traditional technology, this utility model is completely sealed during the measurement process, avoiding the problem of microbial contamination of the medicine solution that may occur when using a measuring cylinder in traditional technology; it will not cause loss or waste of leachate, and increases the yield of leachate; the measurement process is simple and convenient, and can quickly familiarize employees with the opening and closing range of the control valve that meets the process requirements, reducing the workload of employees.

[0024] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
