Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concentration detection and relates to a device for monitoring the concentration of leachate extracted from a percolation tank. Background Technology
[0002] A percolation tank is a device used to extract soluble substances from medicinal materials using a solvent. In most cases, the degree of extraction can be judged by observing the color of the extract. For example, a darker color indicates a higher concentration of soluble substances in the medicinal material, and more solvent can be added to the percolation tank. Conversely, a lighter or even transparent color suggests a lower concentration of soluble substances, and the addition of solvent should be stopped.
[0003] However, for some medicinal materials, the soluble substances are transparent in the extraction solvent, making it impossible to determine the extraction process by color. Furthermore, to avoid contamination by external bacteria, sampling and analysis of the extract are generally not permitted. Therefore, for medicinal materials with transparent extracts, the addition of the extraction solvent is controlled empirically. Inevitably, this leads to problems of adding too much or too little solvent. Adding too much solvent results in waste, while adding too little solvent results in waste of the medicinal material. Utility Model Content

[0022] like Figures 1 to 3As shown, some embodiments of this utility model provide a leachate concentration extraction and monitoring device for a percolation tank 1. The leachate concentration extraction and monitoring device for the percolation tank 1 includes: a percolation tank 1, a first outlet pipe 2, a second outlet pipe 3, a third outlet pipe 4, and a concentration observation component 5. The first outlet pipe 2 is connected to the outlet of the percolation tank 1. The second outlet pipe 3 is connected to the first outlet pipe 2 and includes a transparent outer wall. The third outlet pipe 4 is connected to the second outlet pipe 3. The concentration observation component 5 is disposed on and connected to the second outlet pipe 3, and is configured to collect the concentration of soluble substances in the liquid within the second outlet pipe 3.
[0023] The concentration observation component 5 includes an observation tube 51, a float 52, and a pressure regulating component 53. The observation tube 51 is vertically arranged, with its lower end connected to the second liquid outlet tube 3. A gas pressure gauge is installed at the upper end of the observation tube 51, and an observation port is provided on the side wall of the observation tube 51. The float 52 is disposed inside the observation tube 51, and a reference line is provided on its side wall; the reference line is a horizontal straight line. The pressure regulating component 53 is connected to the upper end of the observation tube 51 and is configured to maintain a constant pressure within the observation tube 51.
[0024] It should be added that the first section of the liquid outlet pipe 2, the second section of the liquid outlet pipe 3, and the third section of the liquid outlet pipe 4 are connected in sequence and connected to the outlet of the percolation tank 1. That is to say, the first section of the liquid outlet pipe 2, the second section of the liquid outlet pipe 3, and the third section of the liquid outlet pipe 4 are all located below the outlet of the percolation tank 1.
[0025] The second outlet tube 3 has a transparent outer wall, such as tempered glass or transparent hard plastic; the colored leaching solvent can be observed through the second outlet tube 3.
[0026] When the leaching solvent is transparent, the concentration of soluble substances in the leaching solvent can be obtained through the concentration observation component 5.
[0027] The observation tube 51 is connected to the second outlet tube 3. The observation tube 51 can be made of transparent tempered glass or transparent hard plastic. The float 52 can be made of hollow glass. The air pressure regulator 53 is connected to the observation tube 51. The air pressure regulator 53 is used to adjust the air pressure in the observation tube 51 to avoid fluctuations in the air pressure in the observation tube 51 caused by changes in the liquid height in the percolation tank 1. This ensures that the float 52 remains at the same height in the liquid in the observation tube 51 after receiving the same buoyancy, thus ensuring the accuracy of the concentration of soluble substances in the leaching solvent.
[0028] In practical use, the gas pressure gauge is used to automatically adjust the gas pressure in the observation tube 51 to a suitable range, for example, to keep the gas pressure in the observation tube 51 at atmospheric pressure.
[0029] Once the float 52 is stable in the observation tube 51, the concentration of soluble substances in the leaching solvent can be calculated by observing the reference mark on the float 52 and the liquid level in the observation tube 51.
[0030] In some embodiments, the float 52 includes: a ballast chamber 521, a main body 522, and a scale 523. The ballast chamber 521 is a conical solid structure. The main body 522 is a vertically arranged circular tube, which is fixedly connected to one side of the plane of the ballast chamber 521, and the main body 522 is smoothly connected to the outer wall of the ballast chamber 521. The scale 523 is a circular rod, which is fixedly connected to the upper end of the main body 522, and a reference mark is provided on the scale 523, which is smoothly connected to the outer wall of the main body 522.
[0031] In some examples, the ballast chamber 521 of the float 52 is a conical solid structure, and the float 52 is a circular tube, which ensures that the float 52 remains vertical in the liquid. Generally, the main body 522 is submerged in the liquid, and the scale 523 is partially submerged in the liquid and partially above it. Multiple graduation lines of the reference scale are set on the scale 523, and the buoyancy force on the float 52 can be calculated by observing the graduation lines that overlap with the liquid surface.
[0032] The buoyancy of float 52 is equal to the gas pressure and gravity. The magnitude of the buoyancy of float 52 is related to the liquid density, and the concentration of soluble substances in the leaching solvent can be determined from the liquid density. The above calculation process is prior art well known to those skilled in the art and will not be elaborated here.
[0033] In some embodiments, the pressure regulating component 53 includes: a pressure regulating cylinder 531, a piston 532, and an electric push rod 533. The pressure regulating cylinder 531 is a tubular component, fixed relative to the observation tube 51, with one end of the cylinder communicating with the upper end of the observation tube 51. The piston 532 is movably disposed within the pressure regulating cylinder 531, its diameter matching the inner diameter of the cylinder 531, and it is sealed to the inner wall of the cylinder 531. The electric push rod 533 is fixed relative to the observation tube 51, and the piston rod end of the electric push rod 533 is fixedly connected to the piston 532.
[0034] In some examples, the pressure regulating cylinder 531 is a tubular component with a diameter larger than that of the observation tube 51. The piston 532 is made of rubber and fits tightly with the outer wall of the pressure regulating cylinder 531 to prevent the observation tube 51 from being connected to the other side of the piston 532 in the pressure regulating cylinder 531, thus preventing external contamination of the observation tube 51.
[0035] The electric push rod 533 is fixedly connected to the piston 532. By controlling the operation of the piston 532, when the air pressure in the observation tube 51 is too high, the piston 532 can move into the air pressure regulating cylinder 531 to reduce the air pressure in the observation tube 51; when the air pressure in the observation tube 51 is too low, the piston 532 can move towards the observation tube 51 from the air pressure regulating cylinder 531 to increase the air pressure in the observation tube 51, so that the air pressure in the observation tube 51 always remains within a small range of fluctuation, wherein the air pressure fluctuation range in the observation tube 51 can be 0.1~0.2 atmospheres.
[0036] In some embodiments, the diameter of the connecting pipe between the observation tube 51 and the second liquid outlet pipe 3 is smaller than the diameter of the main body 522, which can prevent the lower end of the float 52 from entering the observation tube 51 and prevent it from affecting the normal liquid outlet of the leaching solvent.
[0037] In some embodiments, the concentration observation component 5 further includes a protective tube, which is a pipe fitting vertically fixed above the observation tube 51. The protective tube is connected to the upper end of the observation tube 51, and its diameter is smaller than that of the observation tube 51. The gas pressure gauge is connected to the upper end of the protective tube, and its height is above the protective tube.
[0038] In some examples, the protective tube is a transparent glass tube with an inner diameter of 0.5~0.8cm and a length of 10~15cm. The protective tube is connected to the upper end of the observation tube 51, which is also connected to the gas pressure gauge. When the liquid level in the observation tube 51 rises, gas enters the protective tube. Under the action of gas pressure, liquid is prevented from entering the gas pressure gauge, and solvents are prevented from entering the gas pressure gauge, thus avoiding affecting the measurement accuracy and lifespan of the gas pressure gauge.
[0039] In some embodiments, the concentration observation component 5 further includes a controller electrically connected to the gas pressure gauge and the electric actuator 533, the controller being configured to receive a signal from the gas pressure gauge and transmit a signal to the electric actuator 533.
[0040] In some examples, the controller can be a microcontroller, which is electrically connected to the gas pressure gauge and the electric actuator 533. When the gas pressure in the observation tube 51 collected by the gas pressure gauge decreases, the electric actuator 533 can be controlled to push the piston 532 closer to the observation tube 51. When the gas pressure in the observation tube 51 collected by the gas pressure gauge increases, the electric actuator 533 can be controlled to push the piston 532 away from the observation tube 51.
[0041] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
