A nanometer metal cleaning device with integrated functions of crushing and stirring

Abstract

The invention discloses a nano metal cleaning device with a crushing and stirring integrated function. The nano metal cleaning device comprises a motor, an end cover, a cleaning agent inlet, a barrel body, a material outlet, a rotating shaft, a helical ribbon stirrer, a scraper, a sewage drainage opening, a conical end socket and a material inlet, wherein the end cover is arranged on the top of the barrel body; the conical end socket is arranged at the bottom of the barrel body; the material outlet and the sewage drainage opening are formed in the bottom of the conical end socket; the cleaning agent inlet and the material inlet are formed in the side wall of the upper end of the barrel body; the motor is arranged at the top end of the end cover; the torque output end of the motor is connected with the rotating shaft extending into the barrel body; the helical ribbon stirrer and the scraper are arranged on the rotating shaft from top to bottom in sequence; a distance between the scraper and the inner wall of the barrel body and a distance between the scraper and the inner wall of the conical end socket are 5-8mm, respectively. The nano metal cleaning device can be widely applied to cleaning of high-viscosity solids, particularly floccular or mud-block-shaped solids with the certain content of moisture (80 percent).

Description

【Technical field】 [0001] The invention relates to a solid metal particle cleaning device, in particular to a nanometer metal cleaning device with integrated crushing and stirring functions. 【Background technique】 [0002] In recent years, my country's electronics industry has developed rapidly. As the basis of the electronics industry, the printed circuit board (PCB) industry continues to grow at a rate of 14.4% per year. In 2006, China has replaced Japan and has become the world's largest PCB production base. At present, my country The annual output value of the printed circuit board industry has reached 29 billion US dollars. However, in the production process of printed circuit boards, a large amount of wastewater will be generated in the production processes such as copper plating, rinsing, etching, and photocopying. In 2008, the total annual discharge of printed circuit board wastewater in the country was 400 million tons, and it is expected to grow at a rate of 15% eve...

AI Technical Summary

Problems solved by technology

A large amount of wet powder accumulates together, which may form agglomeration, and the density of nano-metal particles is much higher than that of water, and the deposition speed is fast. The bottom of the device causes unfavorable cleaning and blockage of the discharge port
