Description

Technical Field

[0001] The present application relates to the technical field of traditional Chinese medicine processing, and in particular to an alcohol precipitation tank. Background Art

[0002] During the processing of traditional Chinese medicine, an alcohol precipitation tank is often used to extract the effective ingredients of traditional Chinese medicine. The thick paste of the traditional Chinese medicine after water extraction and concentration is added to the alcohol precipitation tank together with ethanol. After heating, stirring and precipitation, the upper clear liquid is taken through the liquid collection tube to complete the alcohol precipitation step. After alcohol precipitation, a paste-like precipitate will accumulate at the bottom of the alcohol precipitation tank, which needs to be heated and stirred for dilution before it can be discharged. The precipitate covers the lower part of the agitator, making it impossible for the agitator to rotate, or requires a large torque to start, which is easy to damage the motor. For this reason, people have designed some devices, such as an alcohol precipitation tank disclosed in Chinese patent application number 201420289416.5. The alcohol precipitation tank includes a tank body with a slag outlet at the lower part, a stirring blade arranged inside the tank body, a pneumatic slag discharge door is provided on the slag outlet, and a pneumatic slag discharge door is provided on the pneumatic slag discharge door. The dynamic slag discharge door is provided with at least one exhaust port connected to a compressed air source, and the compressed gas enters the tank body through the exhaust port. However, during alcohol precipitation, paste-like precipitates easily enter the exhaust port and block the air pipe. Even if air is introduced, the paste-like precipitates cannot be blown away, which increases the difficulty of cleaning. Therefore, an alcohol precipitation tank is required, which is equipped with a hollow agitator. Air can be introduced before stirring is started to loosen the paste-like precipitates. The agitator can be started with a smaller torque, reducing the load on the motor when starting, thereby extending the service life of the motor. Utility Model Content

[0003] In order to solve the above problems, the present application proposes an alcohol precipitation tank, which is equipped with a hollow agitator. Air can be introduced before stirring is started to loosen the paste-like sediment. The agitator can be started with a smaller torque, reducing the load on the motor when starting, thereby extending the service life of the motor.

[0018] like Figures 1 to 2 As shown, an embodiment of the present invention provides an alcohol precipitation tank, comprising: a tank body 1, a jacket 2, an agitator 3, and a motor 4. The jacket 2 is wrapped around the outer periphery of the tank body 1, and the jacket 2 is provided with a steam inlet and a steam outlet, and the steam inlet is connected to the steam source through a steam pipe 5; a mounting bracket 6 is provided on the upper part of the tank body 1, and the agitator 3 is vertically mounted in the middle of the tank body 1 through the mounting bracket 6, and the upper end of the agitator 3 passes through the mounting bracket 6 upward; the motor 4 is mounted on the side of the mounting bracket 6, and the rotating shaft of the motor 4 is perpendicular to the agitator 3, and the rotating shaft of the motor 4 and the agitator 3 are connected to each other through a bevel gear 7; the upper end of the agitator 3 is connected to the air pipe 9 through a rotating joint 8.

[0019] After the Chinese medicine is processed, it is added to the tank body 1. At the same time, ethanol is added, and the motor 4 is turned on to drive the stirrer 3 to rotate so that the Chinese medicine and ethanol in the tank body 1 are fully mixed. After the temperature in the tank body 1 is raised by introducing steam into the jacket 2, the active ingredients in the Chinese medicine are dissolved by ethanol. After stirring for a period of time, it is allowed to stand. After the substances in the tank body 1 are precipitated and layered, the height of the liquid collection pipe is adjusted to drain the upper clear liquid to complete the extraction operation of the active ingredients of the Chinese medicine. When discharging slag, the slag discharge valve is slightly opened to allow the ethanol solution at the bottom of the tank body 1 to flow out, and then the slag discharge valve is closed. Then, clean water is added. First, the valve 16 is adjusted to send the steam in the steam pipe 5 into the air pipe 9 through the bypass pipe 15, and then into the tank body after passing through the rotary joint 8 and the main pipe 10. 1, the high-temperature steam can accelerate the paste precipitate and soften it. At the same time, the steam stirs the clean water and the paste precipitate in the rising process to loosen it. At the same time, the steam is also introduced into the jacket 2 to heat the clean water in the tank body 1 and accelerate the softening of the paste precipitate. At the same time, after 2-3 minutes of steam, compressed air is introduced into the tank body 1 through the switching valve 16 to continue stirring the paste precipitate. After 5-10 minutes of introduction, the paste precipitate around the stirring blade 11 has been loosened. At this time, the motor 4 can be started with a lower load, driving the agitator 3 to rotate and stir the clean water in the tank body 1. The water flow is used to flush the inside of the tank body 1 to loosen the precipitate. Then the slag discharge valve is opened to discharge the precipitate and water to complete the slag discharge operation.

[0020] In a specific embodiment, the agitator 3 includes a main pipe 10 and stirring blades 11. The stirring blades 11 are installed at intervals on the outer periphery of the main pipe 10. The interior of the main pipe 10 is hollow. The upper end of the main pipe 10 is connected to the rotating joint 8. The lower part of the main pipe 10 is provided with a porous baffle 12. The rotating joint 8 adopts the existing rotating joint 8, which can ensure that the main pipe 10 rotates while maintaining the sealing of the connection, so that compressed air or steam can pass into the rotating main pipe 10.

[0021] In a preferred embodiment, the angle between the stirring blade 11 and the horizontal plane is 70° to 80°. When the stirring blade 11 rotates, it can stir the ethanol or water in the tank body 1. Since the stirring blade 11 has a certain angle with the horizontal plane, the ethanol or water also flows in the vertical direction, thereby improving the mixing efficiency. At the same time, when discharging slag, the stirring blade 11 can quickly loosen the paste-like precipitate and discharge it.

[0022] Preferably, a plurality of branch pipes 13 are provided at the lower part of the main pipe 10. The branch pipes 13 are distributed in a ring array at the lower part of the main pipe 10 and are connected to the interior of the main pipe 10. The branch pipes 13 can increase the diffusion area of ​​the gas during blowing. At the same time, the pressure is adjusted by the porous baffle 12 so that part of the gas is blown out from the porous baffle 12 and the other part is blown out from the branch pipes 13.

[0023] Specifically, a support rod 14 is provided at the lower part of the branch pipe 13, one end of the support rod 14 is connected to the lower part of the branch pipe 13, and the other end of the support rod 14 is connected to the main pipe 10. The diameter of the branch pipe 13 is relatively small, and the support rod 14 can improve the bending strength of the branch pipe 13.

[0024] In a preferred embodiment, the air pipe 9 is connected to the steam pipe 5 via a bypass pipe 15. Valves 16 are provided on both the air pipe 9 and the bypass pipe 15. When compressed air needs to be introduced into the main pipe 10, the valve 16 on the bypass pipe 15 is closed, and then the valve 16 on the air pipe 9 is opened. When steam needs to be introduced into the main pipe 10, the valve 16 on the air pipe 9 is closed, and then the valve 16 on the bypass pipe 15 is opened. Thus, the type of gas introduced into the main pipe 10 is adjusted by the cooperation of the two valves 16.

[0025] Specifically, the inner walls of the main pipe 10 and the branch pipe 13 are smooth, and sediment is not easy to adhere to. After steam passes through the inner walls, the sediment attached to the inner walls can be quickly softened and loosened, thereby ensuring the cleanliness of the inner walls.

[0026] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
