Multi-rotating drum type material washing and separation method

Abstract

The invention discloses a multi-rotating drum type washing and separation method. A pipe body having lower water inlets in the side wall is arranged below the inverted frustum-shaped bottom of a machine body, and a settling pipe and upper and lower unloading valves alternately opened and closed are arranged below the pipe body, so that mixed materials with different specific gravities can be effectively washed and separated. Meanwhile, the invention discloses a multi-rotating drum type material washing and separation method; and the upward flow velocity of washing water injected in all the lower water inlets is controlled by the different specific gravities of different materials in the mixed materials through methods of synchronously injecting the washing water through upper and lower water inlets and alternately opening and closing the upper and lower unloading valves, so that the different materials with the specific gravity differences are effectively washed and separated. The effects of progressive separation and progressive increase of the mixed materials are achieved through allocating the gradually decreased upward flow velocity of the washing water injected through all the lower water inlets. Meanwhile, the flow velocity of water flow can be controlled more precisely through flow velocity control devices and flow meters; and the effects of automatic accumulation and unloading are achieved through automatic valves, so that the production continuity is guaranteed.

Description

Technical field [0001] The invention involves a washing separation device and material washing separation method, which specifically involves a drum -type washing separation device and material washing separation method. Background technique [0002] The paper factory that uses waste paper as a raw material will generate 5-8%of the solids per ton of waste paper. The main components are polypropylene, polyethylene film waste plastic and wet paper.Both waste plastic and wet paper are valuable resources that can be renewed. However, because the physical properties are large and mixed together, they need to be fully separated to classify and recycle. Therefore, washing and separating equipment is the key to comprehensive regeneration system. [0003] The existing washing and separating technology uses sediment ditch or sediment tank as a washing and separation device. After the waste plastic is separated, the pellets are divided, and the wet and strong waste paper regularly removes f...

Problems solved by technology

But there is a problem: the pieces of paper sinking at the bottom of the ditch need to be cleaned regularly, and the cleaning time is long, which seriously affects the continuity of production; in order to take into account the production capacity, production cycle and continuity of production, it is necessary to expand the sediment ditch. Length and depth, which will lead to a large footprint and space, which cannot meet the requirements of continuous and large-scale production
