Method and system for crushing and recycling twisted ropes

Abstract

The invention relates to the technical field of paper-making machinery, and in particular relates to a method and a system for crushing and recycling twisted ropes. The recycling method comprises the following process steps of: feeding materials, namely, feeding the twisted ropes to a feeding conveyer belt by using a hanger; roughly crushing, namely, conveying the twisted ropes to a rough crusher to crush so as to make strip rough materials which is 16-25cm long and 5-10cm wide; secondarily crushing, namely, feeding the strip rough materials into a secondary crusher to crush so as to make strip fine materials which are 5-10cm long and 2-8cm wide; and separating and recycling, namely, conveying the strip fine materials to magnetic field effect metal separation equipment to separate, and collecting so as to obtain ferrous metals and non-metal waste. The method and the system have the advantages that the process is simple and developed, the operation is simple, the utilization rate of the raw material is high, and the economic benefits and the social benefits are good.

Description

technical field [0001] The invention relates to the technical field of papermaking machinery, in particular to a method and system for crushing and recycling twisted ropes. Background technique [0002] The twisted rope is produced from the papermaking process, also known as "pulping tailings". Stranded rope is a mixed waste consisting of baled wire, plastic binding waste paper, labels, tape and other waste. It was created to remove trash waste from the pulping process. When pulping, the baled iron wires and bundles of waste paper are thrown into the pulping pulper. The vortex rotation of the pulping pulper makes the iron wires twisted together, and waste plastics and other wastes are pulled by the iron wires. When the rope with the hook is placed into the pulper, the wire and wastes begin to wrap around the rope with the hook and the rope is pulled out together. The vortex effect of the pulper makes the pulled rope Twisted and intertwined, the diameter can reach 2-3 mete...

Problems solved by technology

[0003] Because the twisted rope contains a large amount of iron wire and is large in size, the twisted rope is highly compressed and difficult to break. Therefore, at present, paper manufacturers usually treat the twisted rope as garbage and directly landfill it. The cost of waste treatment is high and the utilization rate of raw materials is low. , increase production costs; in addition, there are also twisted ropes that are sold at a low price as waste products, and the buyer then separates them manually to realize waste recycling, which has low economic benefits.
