[0002] Simply put, the Chinese medicine extraction tank uses the extraction tank to extract the essence of Chinese medicine. The components of the Chinese medicine extraction tank can be divided into extraction tank, condenser, cooler, separator, filter, slag discharge door pneumatic control system, etc.

[0003] In Chinese patent CN201922248611.9, the utility model relates to the technical field of sealing structure, and discloses a sealing structure of a traditional Chinese medicine extraction tank, wherein a sealing ring is provided between a first flange and a second flange, the sealing ring is wedge-shaped, and has a guiding inclined surface protruding toward the inside of the tank body. When the internal force of the tank body acts on the sealing ring between the first flange and the second flange, at this time, the force is decomposed into a horizontal force and a vertical force on the guiding inclined surface, and the sealing ring can be firmly pressed between the first flange and the second flange under the action of the vertical component force. Moreover, the higher the liquid level of the tank body and the greater the pressure, the greater the vertical component force on the guiding inclined surface, and the better the sealing effect of the sealing ring. Even if the flange pressure is uneven, the wedge-shaped self-compensating structure of the sealing ring and the material pressure can be used to fully achieve the self-sealing effect and avoid dripping.

[0004] In order to solve the problem that when the pressure at different places of the sealing ring is uneven, the sealing ring 40 will be subjected to the force from the inside of the tank body 10 to the outside, resulting in a gap between the sealing ring 40 and the flange, the prior art uses the wedge-shaped self-compensating structure of the sealing ring and the material pressure to completely achieve the self-sealing effect and avoid dripping. However, if the outside of the slag outlet is not sealed and protected, leakage is likely to occur when the internal pressure is abnormal.

[0005] Therefore, in view of the above problems, a sealing structure of a Chinese medicine liquid storage tank is proposed. Utility Model Content
