Waste material cleaning and screening device

Abstract

The invention relates to the technical field of waste material cleaning and sorting treatment, in particular to a waste plastic cleaning and screening device. The device comprises a material collecting box, wherein two sides of the material collecting box communicate with a bottom material pumping box and a floating material pumping box separately; a bottom material pumping screw and a floating material pumping screw are arranged in the bottom material pumping box and the floating material pumping box separately; the top of the material collecting box is provided with kick-out devices capable of pushing floating wastes to the floating material pumping screw, and the bottom of the material collecting box is provided with a sinking material pushing screw capable of pushing sinking wastes to the bottom material pumping screw; the kick-out devices and the floating material pumping screw are close to each other; and the bottom material pumping screw and the sinking material pushing screw are close to each other. According to the waste plastic cleaning and sorting device, waste plastics and other mixed objects can be cleaned and screened on a large scale at the same time, so that the treatment capacity is large, the waste treatment capacity per hour in actual production reaches up to 15-20 tons, and waste materials can be treated on a large scale; the waste material cleaning and screening device is simple in structure, not easy to damage, small in energy loss and better in material separation effect; and resource regeneration and cyclic utilization can be achieved.

Description

technical field [0001] The invention relates to the technical field of cleaning and screening of waste materials, in particular to a cleaning and screening device for waste plastics. Background technique [0002] In the existing technology, metal and plastic products are an indispensable part of people's daily life, ranging from building materials to toys, daily necessities, etc., which generally contain metal and plastic mixed materials, and the resulting waste metal Plastic materials are also discarded in large quantities, and the amount of waste materials is also increasing. Therefore, the recycling of waste materials has received widespread attention from all over the world. The recycling of waste materials can not only save a lot of raw materials and energy, but also reduce the environmental pollution caused by waste metal plastics. In the process of recycling waste materials, a series of processing is required for waste materials, so before that, it is necessary to Sc...

Problems solved by technology

The recycling of waste materials can not only save a lot of raw materials and energy, but also reduce the environmental pollution caused by waste metal plastics. In the process of recycling waste materials, a series of processing is required for waste materials, so before that, it is necessary to Screening, separation and cleaning of recycled waste materials. The traditional production mode usually divides the separation and cleaning of waste materials into two different processes, and the separation often adopts manual sorting, which not only reduces productivity, but also increases labor costs.

In order to solve this problem, some cleaning and screening devices for waste materials have appeared in the prior art, but generally the production capacity is low, the separation of materials is not good, the output is small, and the efficiency is low. Generally, the waste processing capacity per hour is only 4~5 tons, waste materials cannot be processed in large quantities
