Description

Technical Field

[0001] The utility model belongs to the field of Chinese medicine preparation equipment, and relates to a Chinese medicine cold precipitation liquid outlet device, which is a cold precipitation tank, and the cold precipitation tank can also be called an alcohol precipitation tank. Background Art

[0002] During the precipitation process of traditional Chinese medicine extracts with ethanol and purified water / water for injection, due to the wide temperature control range, the amount of precipitated residue from different batches of medicine solutions varies greatly, the clarity of the supernatant medicine solution varies greatly, the product quality is unstable, and the production cost is high.

[0003] In addition, the traditional alcohol precipitation tank relies on manual observation and judgment to extract the supernatant of traditional Chinese medicine alcohol precipitation. The liquid extractor is manually operated to observe through the observation hole of the equipment to see whether there is any sediment in the extracted liquid. In this way, it is difficult to accurately determine the end point of supernatant extraction, which increases the labor intensity of employees and poses a quality risk of unstable operation and the risk of quality differences.

[0004] The liquid outlet of the Chinese patent document "CN208591575U" is at the bottom, which is easily blocked by sediment residue. "CN113499613A" controls the height of the liquid outlet by a float, which inevitably has errors. "CN207024722U" inserts a hose into the alcohol precipitation tank to extract the supernatant at the interface between the supernatant and the sediment residue, but it is easy to extract the sediment residue. Utility Model Content

[0005] The utility model aims to provide a traditional Chinese medicine cold precipitation liquid extraction device, which solves the problem of how to better extract the supernatant.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model provides a Chinese medicine cold precipitation and liquid discharging device, comprising:

[0008] A cooling tank, wherein a jacket is arranged on the outer periphery of the cooling tank, a cooling cavity is provided between the jacket and the outer wall of the cooling tank, and an agitator is arranged inside the cooling tank;

[0009] A supernatant liquid storage tank, wherein the supernatant liquid storage tank is provided with a vacuum pipe;

[0010] The liquid collector comprises a liquid collecting pipe and a lifting mechanism, wherein the driving end of the lifting mechanism is connected to the liquid collecting pipe, the inlet of the liquid collecting pipe extends downward into the cold sink tank, the liquid collector also comprises a liquid outlet pipe connected to the liquid collecting pipe, the liquid inlet end of the liquid outlet pipe is connected to the liquid collecting pipe, the liquid outlet end of the liquid outlet pipe is connected to the supernatant storage tank, and the liquid outlet pipe is provided with a liquid outlet flow sensor and a supernatant outlet valve.

[0011] Preferably, the liquid extractor comprises a plurality of proximity switches arranged along the lifting direction of the liquid extracting tube, and the liquid extracting tube is provided with a sensor sheet corresponding to the proximity switch.

[0012] Preferably, a jacket temperature sensor is provided in the cooling chamber, and an in-tank temperature sensor is provided in the cooling tank.

[0013] Preferably, the jacket is provided with a cooling medium inlet pipe and a cooling medium outlet pipe communicating with the cooling cavity, and a connection point between the cooling medium inlet pipe and the jacket is lower than a connection point between the cooling medium outlet pipe and the jacket.

[0014] Preferably, a liquid level meter is provided in the supernatant storage tank.

[0015] Preferably, a vacuum valve is provided on the vacuum pipe, and a vent valve is provided on the supernatant storage tank.

[0016] Preferably, the lower end of the liquid extraction tube is bent, and the bent portion is in a non-perpendicular relationship to the horizontal plane.

[0017] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0018] In the cold sink tank of the utility model, since the liquid taking pipe is liftable, the liquid taking pipe can be placed at a higher position first, so that the supernatant liquid extracted is not easily mixed with sediment residue. The flow value of the liquid outlet flow sensor decreases, and it can be judged that the supernatant liquid above the liquid taking port of the liquid taking pipe has been completely extracted. At this time, the liquid taking pipe can be moved downward to continue to extract the supernatant liquid until the liquid taking pipe has completely extracted the supernatant liquid.

[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 The traditional Chinese medicine cold precipitation and liquid extraction device shown comprises a cold precipitation tank 1, a supernatant liquid storage tank 2, and a liquid extractor 3.

[0027] like Figure 2 The outer periphery of the cold sink tank 1 is provided with a jacket 4, and a foaming material is provided inside the jacket 4 for heat preservation. A cooling cavity 5 is provided between the jacket 4 and the outer wall of the cold sink tank 1. Figure 1 The jacket 4 is connected with a cooling medium inlet pipe 14 and a cooling medium outlet pipe 15. The connection point between the cooling medium inlet pipe 14 and the jacket 4 is lower than the connection point between the cooling medium outlet pipe 15 and the jacket 4. Chilled water is introduced into the cooling medium inlet pipe 14, and the chilled water takes away the heat in the cold sink tank 1 and then flows out from the cooling medium outlet pipe 15.

[0028] like Figure 2 shown Figure 1 In the enlarged view at A in the middle, a tank temperature sensor 13 for detecting the temperature is provided in the cold sink tank 1. A jacket temperature sensor 12 for detecting the temperature of the cooling medium is provided in the cooling chamber 5. This facilitates adjusting the flow of the cooling medium so that the liquid in the cold sink tank 1 reaches a suitable temperature.

[0029] The cold sink tank 1 is provided with a stirrer 6 for stirring the material in the cold sink tank 1. After stirring, there is precipitated residue at the bottom of the cold sink tank 1, and there is a supernatant above the precipitated residue.

[0030] A liquid taking pipe 31 is provided in the cold sink tank 1. The liquid taking pipe 31 is liftable and connected to the driving end of the lifting mechanism 32, and the lifting mechanism 32 drives the liquid taking pipe 31 to rise and fall. The lifting mechanism 32 can be a conventional power mechanism such as a motor and a cylinder.

[0031] like Figure 3 Shown Figure 1 The enlarged view of point B of FIG. 3 shows that a plurality of proximity switches 8 are also provided. A sensor sheet 9 is provided on the liquid collection pipe 31. The proximity switches 8 are distributed in the lifting direction of the liquid collection pipe 31, and the sensor sheets 9 are provided corresponding to the proximity switches 8. When the liquid collection pipe 31 is lifted and lowered to different heights, when the sensor sheet 9 reaches the position of the corresponding proximity switch 8, it is sensed by the proximity switch 8, so that the lifting mechanism 32 can be stopped accordingly, and the liquid collection pipe 31 can be stopped. In this way, the liquid collection pipe 31 can be controlled to gradually descend, so that the supernatant can be extracted by gradually descending. The height of the lowest proximity switch 8 can be determined according to the usual height of the sediment slag.

[0032] A scale 19 is also provided near the bent portion of the upper end of the liquid collection tube 31 , and the scale 19 is convenient for observing the height of the liquid collection tube 31 .

[0033] like Figure 2 , the inlet (lower end) of the liquid taking pipe 31 extends downward into the cold precipitator 1. The lower end of the liquid taking pipe 31 is bent, and the bent portion is not perpendicular to the horizontal plane, that is, the lower end forms an acute angle with the horizontal plane, which is conducive to the supernatant on the upper surface of the slag to flow into the liquid taking pipe 31 easily, and also conducive to the sucked slag (when the lower end of the liquid taking pipe 31 is near the upper surface of the slag) to slide down along the bottom surface of the bent portion.

[0034] like Figure 1 and Figure 3 The upper end of the liquid taking pipe 31 is an outlet, and the outlet is connected to the liquid inlet end of the liquid outlet pipe 33. The liquid outlet end of the liquid outlet pipe 33 is connected to the supernatant storage tank 2. The supernatant sucked by the liquid taking pipe 31 flows into the supernatant storage tank 2 through the liquid outlet pipe 33. The power of suction comes from the vacuum state in the supernatant storage tank 2. The supernatant storage tank 2 is provided with a vacuum pipe 7 for continuous vacuuming. The vacuum pipe 7 is provided with a vacuum valve 17, and the negative pressure in the supernatant storage tank 2 can be maintained by closing the vacuum valve 17. The supernatant storage tank 2 is also provided with a vent valve 18 for quickly breaking the vacuum.

[0035] The liquid outlet pipe 33 is provided with a liquid outlet flow sensor 10 and a supernatant liquid outlet valve 11. The liquid outlet flow sensor 10 is used to monitor the flow in the liquid outlet pipe 33 and to determine whether the supernatant has been pumped to the level of the lower end of the liquid taking pipe 31. The supernatant liquid outlet valve 11 is used to control the on-off of the liquid outlet pipe 33. For example, when stirring, settling and cooling in the cold precipitation tank 1, the supernatant liquid outlet valve 11 can be closed, and the supernatant liquid storage tank 2 can be vacuumed at the same time.

[0036] A liquid level meter 16 is provided in the supernatant liquid storage tank 2 for monitoring the liquid level of the supernatant liquid stored in the supernatant liquid storage tank 2 .

[0037] In summary, in this example, the supernatant can be sucked by gradually lowering the liquid taking pipe 31, so that when the liquid taking pipe 31 is at a higher level, it is not easy to suck the sediment, and the sucked supernatant can be made clearer. And the liquid taking pipe 31 is gradually lowered, so that the clean supernatant can be sucked to a greater extent.

[0038] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
