Vertical bag and bottle breating machine with fixing and moving knife set

Abstract

A vertical waste bag and bottle breaker with coupled static knives and movable knives is composed of a machine frame, such units on the top as motor, speed-reducing belt and material feeding inlet, a breaking casing on the base and with material outlet and 3-6 groups of 4 static knives on its inner surface, a vertical mainshaft in said breaking casing and with 3-6 movable knives, and a frequency variator for changing the rotational speed of motor.

Description

technical field [0001] The invention relates to a bag-breaking and bottle-breaking device for garbage, in particular to a bag-breaking and bottle-breaking device that uses a rotating smooth blade and a stationary sawtooth blade to cut through bags, plastic and paper containers containing urban domestic waste, so that the internal garbage is scattered. Background technique [0002] With the increasing shortage of energy in the world, the output of domestic waste is still increasing rapidly. How to turn useful substances in domestic garbage into valuables has become a research hotspot today. However, in order to realize the reduction, harmlessness, and recycling of domestic waste, the first step is to separate various useful substances. Nowadays, a large amount of domestic waste is bagged, and bag breaking technology has naturally become the first problem to be solved. [0003] At present, the commonly used bag breaking devices are widely borrowed from the fields of agricult...

Problems solved by technology

[0003] At present, the commonly used bag breaking devices are widely borrowed from the fields of agriculture and mining, or directly copy the devices in foreign garbage treatment processes. The core technology tool is not only used to break the garbage bags, but also bears the gravity of the falling garbage and the rotation generated by the garbage. Impact force and other effects, the damage rate is high; and this kind of technology tends to over-shred the garbage, which is not conducive to the subsequent sorting process, and it is difficult to effectively separate useful substances

For example, the vertical garbage bag breaking machine (patent number: 00223653), the blade-shaped blade is directly installed on the shaft, and is directly impacted by the garbage, and the rotating chain will hammer and crush the garbage; The cutting-based rotary crushing (bag breaking) method, bricks, glass and other inorganic brittle materials are excessively crushed, and they are mixed with organic waste with high moisture content, which cannot be effectively separated, directly affecting the composting quality of subsequent rotten organic matter

Especially after waste batteries and other heavy metal-rich garbage are crushed, not only is it difficult to effectively sort, but also leachate will be precipitated, causing secondary pollution
