A vertical hammer-roller composite crushing and shredding machine for crushing thin-walled shell objects of electronic waste

Abstract

The invention relates to the field of crushing machines, in particular to a crushing machine for machining waste electronic trash thin-wall shell devices such as televisions, computers, fax machines, printers, copying machines and refrigerators, and provides a vertical hammer and roller composite crushing and cutting-up machine for crushing electronic trash thin-wall shell objects. According to the vertical hammer and roller composite crushing and cutting-up machine, three processes of vertical hammer crushing, roller crushing and roller (rotary) cutting are integrated, and the work efficiency and the crushing reliability are improved. The vertical hammer and roller composite crushing and cutting-up machine comprises an upper shell and a lower shell. The upper shell and the lower shell are arranged up and down to form a crushing bin. A feeding opening is formed in the top of the upper shell. A hammer shaft is arranged in the crushing bin. The top of the hammer shaft is connected to the middle of the top of the upper shell through a bearing pedestal, and the bottom of the hammer shaft stretches out of the bottom of the lower shell. The hammer shaft is connected to the middle of the bottom of the lower shell through a bearing pedestal, and the hammer shaft acts through a belt conveying mechanism. According to the vertical hammer and roller composite crushing and cutting-up machine, the crushing reliability is improved, and high adaptability is achieved.

Description

technical field [0001] The invention relates to the field of crushing machinery, in particular to a crushing machine for processing discarded TVs, computers, fax machines, printers, copiers, refrigerators and other electronic waste thin-walled shell devices. Background technique [0002] The first step in physical treatment of e-waste is to crush the e-waste, which is the key process of this treatment method. Crushing equipment generally includes hammer crusher and roller crusher. Thin-walled shell objects of electronic waste, such as TV casings, computer casings, fax machine casings, copier casings, etc., after removing toxic substances such as TV picture tubes and fluorescent screens, are mostly formed of thin steel plates, so use a hammer to remove them. It is difficult for the crusher to break into small pieces of material after repeated hammering, and the crushing efficiency is low and the effect is poor; due to its large size, it is difficult for the shell to enter th...

Problems solved by technology

Thin-walled shell objects of electronic waste, such as TV casings, computer casings, fax machine casings, copier casings, etc., after removing toxic substances such as TV picture tubes and fluorescent screens, are mostly formed of thin steel plates, so use a hammer to remove them. It is difficult for the crusher to break into small pieces of material after repeated hammering, and the crushing efficiency is low and the effect is poor; because of its large size, it is difficult for the shell to enter the roller of the roller crusher when it is crushed by the roller crusher, and it is difficult to bite into it. The crushing efficiency is not ideal either, the shell needs to be crushed first and then crushed
