Description

Technical Field

[0001] The utility model belongs to the pharmaceutical field, in particular to a precipitation removal device. Background Art

[0002] Traditional Chinese medicine decoctions often contain impurity precipitation, and currently the alcohol precipitation method is mostly used to separate the impurity precipitation. Since the alcohol precipitation method requires the effective components in the traditional Chinese medicine decoction to be extracted by ethanol and then the impurities are separated, it not only requires other substances to be mixed into the traditional Chinese medicine decoction, but also easily leads to the waste of effective components.

[0003] Compared with the alcohol precipitation method, the physical precipitation method does not require the addition of ethanol, thus avoiding the risk of other substances being mixed in. Figure 1 The figure shows a deprecipitation device currently used for physical sedimentation of Chinese medicine decoction, including a sedimentation tank 1, wherein outlets 10 are respectively arranged at the bottom and the middle of the sedimentation tank 1, and a blocking device or a valve can be arranged on the outlet 10. After the Chinese medicine decoction is poured into the sedimentation tank 1, it is left to stand until the supernatant and the precipitate are separated, the supernatant in the Chinese medicine decoction is discharged through the outlet 10 in the middle of the sedimentation tank 1, and the precipitate in the Chinese medicine decoction is discharged through the outlet 10 at the bottom of the sedimentation tank 1, thus completing the separation of the supernatant and the precipitate.

[0004] The above-mentioned deprecipitation device has some disadvantages during use. First, since the outlet 10 in the middle of the precipitation tank 1 is set on the side wall, the Chinese medicine decoction that has been precipitated inside is greatly disturbed during the discharge of the supernatant, which easily causes the stratified medicinal liquid in the precipitation tank 1 to be mixed again, and the separation effect is not thorough enough; secondly, since the setting height of the outlet 10 in the middle of the precipitation tank 1 is fixed, each deprecipitation device can only be applied to a fixed amount of Chinese medicine decoction, or can only be applied to Chinese medicine decoction with fixed supernatant and precipitate layer heights, and the adaptability is poor. Utility Model Content

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide a deprecipitation device to achieve the purpose of being applicable to Chinese medicine decoctions of different volumes and separating the supernatant from the precipitate more thoroughly.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a de-precipitation device comprises a sedimentation tank, the bottom of the sedimentation tank is connected with a sedimentation outlet for sediment discharge, a supernatant guide pipe for supernatant discharge is passed through the sedimentation tank, one end of the supernatant guide pipe passes through the sedimentation tank and extends out, and a valve or a plugging part is arranged at the end, the other end of the supernatant guide pipe extends into the sedimentation tank along the height direction, and the height is higher than the liquid height in the sedimentation tank, a plurality of outer guide holes are arranged on the supernatant guide pipe along the height direction, an inner sleeve matched with the inner diameter of the supernatant guide pipe is arranged on the inner sleeve, and an inner guide hole matched with the outer guide hole is arranged on the inner sleeve, and the inner sleeve is rotated or moved so that the inner guide hole and the outer guide hole are staggered, overlapped or partially overlapped.

[0007] As a limitation of the present invention: one inner flow guide hole is provided, and the size of the inner flow guide hole is the same as that of the outer flow guide hole.

[0008] As a limitation of the present invention: a handle is fixedly provided at one end of the inner sleeve away from the sedimentation tank.

[0009] As a limitation of the present invention: a limiting protrusion is fixedly provided on one end of the inner sleeve near the handle, and when the limiting protrusion abuts against the outer sleeve, the inner guide hole is at the same height as the outer guide hole at the bottom.

[0010] As a limitation of the present utility model: one end of the supernatant guide pipe located in the sedimentation tank is located at the center of the sedimentation tank.

[0011] As a limitation of the present invention: the sedimentation tank comprises a conical portion with one end facing the ground and a cylindrical portion with one end away from the ground, and the sedimentation outlet is arranged at the tip of the conical portion.

[0012] As a limitation of the present invention: the sedimentation outlet comprises a sedimentation guide pipe connected to the sedimentation tank, and a valve or a plugging portion is provided at one end of the sedimentation guide pipe away from the sedimentation tank.

[0013] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] (1) The utility model is provided with a supernatant liquid guide pipe that runs through the sedimentation tank. The supernatant liquid guide pipe is provided with external guide holes of different heights. By adjusting the height of the inner sleeve, the inner guide hole is overlapped with the external guide holes of different heights, so that supernatants of different heights are discharged and different amounts of liquid medicine are separated. The utility model has strong adaptability and also has the function of flow regulation when partially overlapping.

[0015] (2) The utility model extends the supernatant liquid guide pipe to the inside of the sedimentation tank, changing the side wall drainage to the center drainage, which causes less disturbance to the liquid and can effectively avoid the remixing of the stratified liquid in the sedimentation tank during the supernatant liquid discharge process, so that the supernatant and the sediment are separated more thoroughly.

[0016] In summary, the utility model can separate different amounts of liquid medicine, has strong adaptability and can adjust the flow rate, has less disturbance to the liquid, and makes the separation of the supernatant and the precipitate more thorough, and is suitable for the separation of all liquid supernatants and precipitates.

[0025] Example Deprecipitation Device

[0026] In this embodiment, Figure 2 to Figure 4As shown, a de-precipitation device includes a precipitation tank 1. The precipitation tank 1 is a tank body along the height direction. The precipitation tank 1 is made of transparent material and includes a conical portion 11 at one end facing the ground and a cylindrical portion 12 at one end away from the ground. A leg 13 is fixed at the lower end of the cylindrical portion 12. The upper end of the cylindrical portion 12 is open, and a cover that matches the upper end opening of the cylindrical portion 12 can be selected as a cover of the precipitation tank 1 as needed (not shown in the figure). The tip of the conical portion 11 is connected to a precipitation outlet for precipitation discharge. The precipitation outlet includes a precipitation guide pipe 2 connected to the precipitation tank 1. The end of the precipitation guide pipe 2 away from the precipitation tank 1 is provided with a faucet 3. Of course, the faucet 3 can also be replaced with other liquid valves, or a detachable plugging portion can be provided at the end of the precipitation guide pipe 2.

[0027] A supernatant liquid guide pipe 4 for discharging supernatant liquid passes through the conical portion 11 of the sedimentation tank 1. One end of the supernatant liquid guide pipe 4 passes through the sedimentation tank 1 and extends in a horizontal direction. A faucet 3 is provided at the end. Of course, the faucet 3 can also be replaced by other liquid valves, or a detachable sealing portion can be provided at the end. The other end of the supernatant liquid guide pipe 4 extends into the sedimentation tank 1 in the height direction, and the height is higher than the liquid height in the sedimentation tank 1. The position is located at the center of the sedimentation tank 1, that is, the axis, so as to reduce the disturbance caused by the discharge.

[0028] Several outer flow guide holes 5 penetrating the side wall of the supernatant flow guide tube 4 are arranged on the supernatant flow guide tube 4 in the height direction. An inner sleeve 6 matching the inner diameter of the supernatant flow guide tube 4 is provided in the movable sleeve of the supernatant flow guide tube 4. Matching here means that the outer diameter of the inner sleeve 6 is equal to or slightly smaller than the inner diameter of the supernatant flow guide tube 4, so that the inner sleeve 6 can rotate or slide in the supernatant flow guide tube 4 under the action of external force. When the external force is removed, the inner sleeve 6 can also remain relatively fixed with the supernatant flow guide tube 4 under the action of friction. An inner flow guide hole 7 matching the outer flow guide hole 5 is arranged on the inner sleeve 6. In this embodiment, one inner flow guide hole 7 is arranged, and the size of the inner flow guide hole 7 is the same as that of the outer flow guide hole 5. The inner sleeve 6 is rotated or moved so that the inner flow guide hole 7 is staggered, overlapped, or partially overlapped with the outer flow guide hole 5. When the inner guide hole 7 is staggered with the outer guide hole 5, the outer guide hole 5 is completely blocked by the tube wall of the inner sleeve 6. At this time, the supernatant guide tube 4 is in a closed state. When the inner guide hole 7 completely overlaps with one of the outer guide holes 5, the outer guide hole 5 is in an open state. At this time, the tap 3 of the supernatant guide tube 4 is opened to discharge the supernatant. By pulling out or pressing down the inner sleeve 6, the inner guide hole 7 is overlapped with the outer guide holes 5 at different heights, so that the supernatant at different heights can be discharged. The device can separate different amounts of liquid medicine and has stronger adaptability. When the inner guide hole 7 partially overlaps with one of the outer guide holes 5, the flow rate regulation can be achieved by rotating the inner sleeve 6. Of course, the number of the inner guide holes 7 can also be changed to increase the height range of simultaneous liquid discharge, and multiple inner guide holes 7 of different heights can also be set along the circumference of the inner sleeve 6. By rotating the inner sleeve 6, the inner guide holes 7 and the outer guide holes 5 can be staggered, overlapped, or partially overlapped.

[0029] In order to facilitate the application of external force to the inner sleeve 6, a handle 8 is fixedly provided at one end of the inner sleeve 6 away from the sedimentation tank 1. Furthermore, a scale (not shown in the figure) can be set on the inner sleeve 6 to facilitate the operator to clearly understand the relative positions of the inner flow guide hole 7 and the outer flow guide hole 5. A limiting protrusion 9 is fixedly provided on one end of the inner sleeve 6 near the handle 8. When the limiting protrusion 9 abuts against the outer sleeve, the inner flow guide hole 7 is at the same height as the outer flow guide hole 5 at the bottom, which has a positioning effect.

[0030] When using this embodiment, pour the Chinese medicine decoction to be separated into the precipitation tank 1 and let it stand until the supernatant and the precipitate are separated, move the handle 8 to make the inner guide hole 7 overlap or partially overlap with the outer guide hole 5 at the same height as the supernatant, open the tap 3 on the supernatant guide pipe 4, and slowly discharge the supernatant. After the supernatant is completely discharged, close the tap 3 on the supernatant guide pipe 4, open the tap 3 on the precipitation guide pipe 2, and discharge the precipitate to complete the separation of the supernatant and the precipitate. It should be noted that this device can be applied to both batch production and laboratory operation.
