Smoke heating traditional Chinese medicine extraction tank

Abstract

The invention discloses a smoke heating traditional Chinese medicine extraction tank. The smoke heating traditional Chinese medicine extraction tank comprises a feeding opening, a liquid inlet, a washing opening, support feet and a tank body. The tank body is provided with a heat preservation layer for heat insulation; one side of the tank body is provided with an air cylinder linkage device for controlling bottom residue discharging; the air cylinder linkage device is hinged to the bottom of a sealing cover; the bottom of the tank body is provided with a residue outlet; an air cylinder drivesan opening shaft to enable a residue outlet door of the residue outlet to be open or close and to lock the door; a smoke inlet is formed in one side of the tank body; a smoke outlet is formed in theother side of the tank body; a spiral piece channel for smoke flowing is formed between the inner wall and the outer wall of the tank body; smoke flows in along the tangential direction of a cylinderwall; the lower end of a spiral piece enters the interlayer along the tangential direction of the inlet and the cylinder wall; the bottom is provided with a disc for heating; spiral sheets are arranged in the disc; the spiral sheets are arranged in a mode of combining clockwise flowing-in and anticlockwise flowing-out; the spiral sheets are inserted into the disc in an intersecting mode; the discis placed in a sealing cover structure connected with an upper-layer cylinder body; and the lower disc is connected with the tank body through a pneumatic locking structure.

Description

technical field [0001] The invention relates to a flue gas heated traditional Chinese medicine extraction tank, which uses high-temperature flue gas as a heat source to heat the traditional Chinese medicine to complete the extraction process, and is suitable for the fields of traditional Chinese medicine and food processing. Background technique [0002] Natural gas has become the main fuel to solve energy and environmental problems. As a clean energy, compared with fossil fuels such as coal, the combustion products of natural gas are cleaner and greener. The flue gas obtained by direct combustion of natural gas is used as the heat source for production instead of high-temperature steam, and the energy saving rate can reach 30%. In response to the call of "coal to gas", the use of natural gas direct combustion to realize the extraction process of traditional Chinese medicine has important energy-saving significance. [0003] The conventional heating method of the extractio...

Problems solved by technology

This method has been widely used, but the common disadvantage is that the heat medium inside the jacket of the extraction tank is high-temperature and high-pressure steam, and a pressure vessel is required. The production requirements of the equipment are high, and there are certain safety hazards in the operation process.

[0004] Aiming at problems such as complex heat exchange equipment and weak heat exchange performance, people have also improved it. Among the existing patented technologies, the patented technology of a company in Anhui (Chinese patent ZL201721244117.x for a traditional Chinese medicine extraction equipment) is in the interlayer When heating inside, the electromagnetic heating coil is used. Although the device that converts electrical energy into heat energy through the principle of electromagnetic induction has certain advantages, because the electromagnetic is close to the heated body, it needs high-temperature resistant high-temperature wire to wind, which is harmful to the material. The requirements are relatively high; especially for the traditional Chinese medicine extraction tank mentioned in this application, a large area of ​​heating area is required, the amount of consumables is large, and the cost is very high
