Description

Recovery device for recovering diamond Technical Field The invention relates to the technical field of diamond recovery, in particular to a recovery device for diamond recovery. Background Since the birth of 1880, various matrix materials are designed for fully playing the role of diamond by the diamond sawing tool and the grinding tool which are greatly developed in 1970, so as to meet the requirements of the tool performance, the processing material and the processing mode. The diamond tool with metal as matrix is made of diamond as cutting and grinding material, metal powder as matrix material and through powder metallurgy, pressing, sintering and machining. The main components of the metal-based diamond tool bit are diamond, iron, nickel, copper, cobalt, tin, zinc and the like. In the production and use process, a large amount of waste products and residual cutter heads are generated, and the recycling value is realized. Chinese patent with the issued publication number CN213802930U discloses a waste diamond tool recovery device. The recycling device comprises a precipitation cylinder, a stirring tank, a first conveying pump and a filter screen, wherein a feeding pipe is arranged between a discharge hole of the precipitation cylinder and a feeding hole of the stirring tank, the first conveying pump is used for conveying materials in the stirring tank to the filter screen, the stirring tank comprises a tank body, the stirring device is arranged in the tank body, a cleaning ring pipe coaxially arranged with the tank body is arranged in the tank body, a plurality of spray holes facing the inner wall of the tank body are formed in the cleaning ring pipe, a liquid inlet pipe communicated with the cleaning ring pipe is connected to the cleaning ring pipe, a driving motor is arranged at the upper end of the tank body, a screw rod is fixedly connected to an output shaft of the driving motor, a connecting plate is connected to the liquid inlet pipe, and the connecting plate is in threaded fit with the screw rod.
