Problems solved by technology

[0004] However, since the existing double-cone rotary vacuum drying device is formed by the rotating connection between the frame and the drying cylinder, there is a certain gap between the drying cylinder and the ground, and in a single drying, the general powder addition amount is the drying cylinder 30-50% of the volume, and manual feeding is generally used for feeding. When feeding and discharging, the powdery copper powder particles collide with each other to form flying dust, which will affect the working environment and cause material leakage

Abstract

The invention provides a double-cone rotary vacuum drying device and feeding method for copper powder drying, and relates to the field of copper powder production drying. The double-cone rotary vacuumdrying device comprises a machine frame; a drying cylinder rotationally connected with the machine frame is arranged on the machine frame, a port pipe is arranged at one end of the drying cylinder, asealing disc coaxially and relatively sliding with the port pipe is arranged at the port pipe, a material conveying mechanism is arranged on the machine frame and comprises a material conveying box fixed to the bottom end of the machine frame, an inserting barrel sliding in the axial direction of the material conveying box is arranged in the material conveying box, the inserting barrel is connected with the port pipe in an inserted mode, a material conveying shaft is fixedly connected into the inserting barrel in the axial direction, the top end of the material conveying shaft is connected with a threaded sleeve fixedly connected with the bottom end of the sealing disc in the radial direction, and a lock hole is formed in the side face of the joint of the sealing disc and the port pipe. According to the double-cone rotary vacuum drying device and the feeding method for the copper powder drying, feeding and discharging are sealed, and the situation that in the feeding or discharging process, copper powder is impacted, and consequently dust is excited, and the air quality in the working environment is affected is avoided; and meanwhile, loss of the copper powder caused by splashingis avoided.

Description

technical field [0001] The invention relates to the field of copper powder drying, in particular to a double-cone rotary vacuum drying device and a feeding method for copper powder drying. Background technique [0002] The production of copper powder is used in metallurgy. The processing process of copper powder production is as follows: the copper material is cut, the copper material cut into small sections is melted at high temperature, the copper liquid is processed by atomization to form copper powder, and the copper powder is cooled The final copper powder is dried, the processed copper powder is ground to crush the hardened copper powder, and finally packaged and sold. In the drying process, the copper powder is dried at a low temperature to avoid oxidation of the copper powder. Therefore, a vacuum drying device is used. The principle is to dry the copper powder The air pressure in the cavity where the powder is located is reduced, thereby reducing the boiling point of...
