The extraction tank is a leaching extraction equipment commonly used in pharmaceutical and chemical industry, and is particularly suitable for the leaching extraction of the components contained in the plant products. An auger or a rotary propeller with a tank body and an axial position inside the tank is connected with a rotating shaft disk outside the tank body and is characterized in that a set of continuous countercurrent leaching extraction single tanks are arranged obliquely and mutually. The feed port is connected with the feed port to form a communicator. Each single tank has a feed inlet at the upper end of the lower tank and a residual liquid discharge port at the lower part. The upper end of the tank has an inlet or exhaust port, and the lower part has outlets. Material mouth.
The extraction tank is a multi-purpose device designed for the Chinese medicine factory, cooking and extraction process. It can be extracted in this process, alcohol recovery, volatile oil separation. In addition to the main equipment of the extraction tank, this equipment is also equipped with a foam-clogging device, a cooler, a water-oil separator, and the like. These devices are made of stainless steel where they are in contact with drugs. The heating sandwich is strictly tested by the pressure vessel inspection department of Wenzhou City and is safe and reliable, and the equipment has a long service life. In the extraction process, the equipment is completed by a condenser, oil-water separator, etc., and is completely sealed and closed in a recyclable system. At the same time, the organic solvent is recovered in the waste residue.
Changzhou Lima Drying Engineering Co., Ltd. extraction tank extraction principle:
(1) Water extraction: water and traditional Chinese medicines are loaded into the extraction tank and begin to heat the interlayer. After the boiling in the tank, the supply of heat is reduced and the boiling in the tank is maintained. The maintenance time depends on the extraction pharmacological process. For example, the closed extraction needs cooling. The water vaporizes the steam and returns it to the extraction tank, keeping the circulation and temperature.
(2) If alcohol is added, the medicine and alcohol must be sealed in the tank first, and heat source steam should be sent to the interlayer to open the cooling water so that the supply of heat can be reduced when the temperature reaches the required temperature, so that the ascending vaporous alcohol passes through the condenser and returns to liquid alcohol. Can, in order to improve efficiency, the pump can be forced to circulate, so that the liquid from the bottom of the tank through the pump to the top of the upper cylinder inlet back to the tank, lifting the local channel flow.
(3) Extracting oil: first add the Chinese medicine and water containing volatile oil into the extraction tank, open the circulation valve of the oil separator, adjust the bypass return valve, open the valve for the supply of heat source to reach the volatilization temperature, turn on the cooling water for cooling, and cool The liquid chemical should be kept at a certain height in the separator to separate it, and another oil-water separator should be used alternately.
(4) Recovery of olein: Add alcohol into the cylinder, open the cooling water for the vapor, and then open the recovery valve.

Other Special Steel Is different from the traditional steel, it is mainly formed by the alloy, generally has good oxidation resistance, corrosion resistance, high temperature resistance and other characteristics, it can be applied in a very harsh environment. Used for special industries. The main use is the production of various furnace components, the maximum temperature of 1300 degrees Celsius, could be applied in the condition of high temperature 1150℃. Such as furnace materials, automotive cleaning equipment, materials, etc.. As well as nuclear reactor cooling system, heating furnace, carburizing basket and fasteners, heat treatment fixture.
