The abamectin has unique insecticidal mechanism, can block nerve conduction of invertebrates, has long duration, has stronger killing power to various insects, mites and animal parasites, and is easy to decompose in water and soil, so the abamectin does not pollute the environment. The abamectin as a novel biological pesticide has the excellent characteristics of high efficiency, low toxicity, wide application range and the like.

At present, in the extraction process of abamectin, dried abamectin mycelia are mixed with 4-8 times of leaching liquor or ethanol, stirred and leached in a leaching tank for 2-3 hours, and then the leaching liquor is discharged from the leaching tank and used for further refining and preparation. The prior Chinese patent with the reference publication number of CN201410309Y discloses a leaching tank for preparing abamectin, which comprises a tank body, stirring blades, a residue outlet, a solvent inlet, a leaching solution outlet, a hypha inlet and a stirring motor, wherein the hypha inlet is arranged above the tank body, and the leaching tank is characterized in that the tank body is internally provided with a plurality of layers, and the stirring blades are arranged above each layer. When carrying out the leaching, import the interpolation from the hypha with kibbling avermectin hypha, jar body top mixer drives stirring vane and stirs the hypha, and the menstruum is flowed in from the menstruum inlet by the high position, and the successive layer goes upward, and with descending hypha reverse contact, accomplish the leaching, and the leaching liquid goes upward jar body top and flows out from the leaching liquid export, and residue jar body bottom residue export is discharged.

In view of the above-mentioned related technologies, the inventor believes that there are defects that the leaching solution remained in the residue is directly exposed to the external environment after the residue is discharged, which wastes raw materials and harms human body.

SUMMERY OF THE UTILITY MODEL

In order to improve the avermectin hypha leaching process, the leaching liquor of surviving directly exposes in the external environment in the hypha residue, extravagant raw materials and endanger the problem of human body, this application provides an extraction device for avermectin production.

The application provides a leaching device for abamectin production adopts following technical scheme:

a leaching device for abamectin production comprises a tank body, wherein the top of the tank body is provided with a hypha inlet, a liquid inlet and an air inlet, the bottom of the tank body is provided with a liquid outlet, the inner wall of the tank body is fixedly connected with a filter plate, the bottom of the filter plate is communicated with a residual liquid guide pipe, the residual liquid guide pipe penetrates through the bottom of the tank body, the bottom of the residual liquid guide pipe is communicated with a recovery box, a gap is reserved between the recovery box and the tank body, a valve is arranged on the residual liquid guide pipe between the recovery box and the tank body, the top of the recovery box is provided with an air outlet, an electric heating material receiving plate is horizontally arranged in the recovery box and is in sliding connection with the inner wall of the recovery box, the bottom of the electric heating material receiving plate is provided with a lifting cylinder capable of driving, the side wall of the recovery box opposite to the slotted hole is provided with a slag outlet.
