Flue gas heating traditional chinese medicine draws jar

Technical Field

The utility model relates to a flue gas heating traditional chinese medicine draws jar, it uses the high temperature flue gas as the heat source, and the process of drawing is accomplished to heating traditional chinese medicine, is applicable to traditional chinese medicine and food processing field.

Background

Natural gas has become the primary fuel to solve energy environmental problems. As a clean energy source, compared with fossil fuels such as coal, natural gas has clean and green combustion products. The flue gas obtained by direct combustion of natural gas is used as a heat source for production to replace high-temperature steam, and the energy saving rate can reach 30%. In order to respond to the call of changing coal into gas, the method for realizing the extraction process of the traditional Chinese medicine by adopting natural gas direct combustion has important significance for saving energy.

The conventional heating mode of the extraction tank is to heat the liquid medicine in the cylinder by high-temperature steam through a jacket. The method has been widely applied, but the method has the general defects that the heating medium in the jacket of the extraction tank is high-temperature high-pressure steam, a pressure container is needed, the production requirement of equipment is met, and certain danger exists in the operation process.

Aiming at the problems of complex heat exchange equipment, weak heat exchange performance and the like, people also reform the equipment, in the existing patent technology, an electromagnetic heating coil is adopted when the patent technology (Chinese patent ZL201721244117.x of Chinese medicine extraction equipment) of Anhui company heats an interlayer, and a device for converting electric energy into heat energy by an electromagnetic induction principle has certain advantages, but because the electromagnetism is close to a heated body, high-temperature-resistant high-temperature wires are needed for winding, and the requirement on materials is high; especially for the traditional Chinese medicine extraction tank mentioned in the patent, a large area of heating area is needed, the consumption amount of the traditional Chinese medicine extraction tank is large, and the cost is high.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a flue gas heating traditional chinese medicine draws jar, this heating device draw the heat of jar make full use of flue gas, make it directly heat drawing the jar. The extraction tank has the advantages of convenient operation, simple manufacturing process, low failure rate, low running cost and the like; meanwhile, the liquid medicine in the extraction tank can be heated more uniformly, the efficiency is higher, the medicine is more fully dissolved, and more effective components are extracted.

The utility model provides a technical scheme that technical problem adopted is: a flue gas heating traditional Chinese medicine extraction tank is designed, and comprises a feeding port, a liquid inlet, a flushing port, support legs and a tank body, wherein the tank body is externally provided with a heat insulation layer for heat insulation, one side of the tank body is provided with a cylinder linkage device for controlling bottom deslagging, the device is hinged at the bottom of a sealing cover, the bottom of the tank body is provided with a slag outlet, and the slag outlet is driven by a cylinder to open and close an opening shaft to complete opening and closing of a door and lock the slag outlet; a flue gas inlet is formed in one side of the tank body, a flue gas outlet is formed in the other side of the tank body, a spiral plate channel for flue gas to flow is arranged between the inner wall and the outer wall of the tank body, the flue gas flows in along the tangential direction of the wall of the tank body, the lower end of the spiral plate, the inlet and the wall of the tank body tangentially enter the interlayer, and the bottom of the spiral plate is heated by; the spiral plates are arranged in the disc in a combined mode of clockwise inflow and anticlockwise outflow, and are inserted into the disc in an intersecting mode; the disc is placed in a sealing cover structure connected with the upper layer cylinder body, and the lower disc is connected with the tank body through a pneumatic locking structure.

Flue gas flow in along section of thick bamboo wall tangential direction to up spiral flow is down followed to the passageway that constitutes along the flight, the flue gas flows along section of thick bamboo wall tangential direction in the upper end.

The flight constitute flue gas flow channel, two flight intervals are the width of passageway, interbedded clearance is the height of passageway.

The helical blade plays the effect of fin, can strengthen the convection heat transfer between flue gas and the section of thick bamboo wall.

The disc is the bottom heater block, sets up the flight in the disc, and the flight mode of arranging combines together for clockwise inflow and anticlockwise outflow, and the flue gas flows in from the flight tangential, and the flight is crossing in inserting the disc to open through bottom heating valve and flowmeter control heating with the flow size.

The utility model discloses a flue gas heating traditional chinese medicine draws jar, compared with the prior art, has following beneficial effect:

1, the flow field is improved, and the flow is sufficient. The flue gas flows in the channel that the flight constitutes, with draw jar section of thick bamboo wall full contact, avoids flowing the dead zone.

2 the heating effect is better. The flow direction of the smoke in the sleeve is downward inlet and upward outlet, so that the temperature of the liquid medicine at the lower part is higher, the temperature of the liquid medicine at the upper part is low, and because the temperature difference exists in the fluid, the density of the fluid at each part is different, and the density of the fluid with high temperature is small, so that the temperature is inevitably increased; the fluid with low temperature has high density and is necessarily reduced, thereby causing the flow inside the fluid and promoting better heating effect.

3 is heated more uniformly. The extraction tank is heated up and down, so that the heating is more uniform. If the jacket is used for heating only, when the inner diameter of the tank body is larger, the material in the center of the tank body is heated relatively slowly, and the material is heated unevenly. The disc is arranged at the bottom of the extraction tank, and the flue gas flows more fully in the disc by utilizing the spiral sheet in the disc, so that the effectiveness of extracting the liquid medicine is greatly improved.

4 the flue gas flows in along the tangential direction of the cylinder wall, so that the flow resistance is reduced.

5 adding a spiral sheet. The distance between the two spiral sheets is the channel width, and the interlayer gap is the channel height. Because the design has self-cleaning function in the flowing process of the flue gas, when the fluid in a single channel passes through the impurity deposition position in the channel, the flow velocity is relatively improved, the impurities are easily washed away, and the dust cannot be deposited at the outlet; the bent spiral channel plays a supporting role, so that the small flow resistance in the channel in a turbulent state of the fluid is favorably enhanced, the design flow speed can be improved, and the heat transfer coefficient is favorably improved; the spiral sheet plays a role of a fin, has a compact structure, is beneficial to improving the heat transfer area in unit equipment volume and enhancing heat transfer.

6 the utility model discloses there is not the comdenstion water problem, to the required temperature of traditional chinese medicine boiling be higher than 100 ℃, the exhanst gas outlet temperature need be higher than 100 ℃, can not have the problem of comdenstion water, so, to the method that uses the flue gas to heat, can effectively promote the rate of heating of material, shorten heat time, improve and draw the benefit.
