Problems solved by technology

The former requires the installation of a power system and has high requirements for the sealing of the feed hopper; the latter has limited vacuum generated by the induced draft fan, and different particles of solid waste need to be installed with different induced draft fans, which is very restrictive in use

Embodiment Construction

[0027] The specific embodiment of the present invention is that the broken waste printed circuit boards are sorted by shaking table, such as image 3 Shown is the flow chart of solid waste treatment wind separation process, in which 9 is the SSR-50 three-lobe Roots blower; 10 is the flow meter; 11 is the jet suction particle material wind separator; 12 is the heavy material tank; 13 is Medium material tank; 14 is a light material tank; 15 is an air outlet; 16 is a discharge port.

[0028] The crushed waste printed circuit boards are sorted by a shaking table, and then the intermediate product sorted by the shaking table is sent to a jet suction particle material wind separator for separation. The diameter of the nozzle of the wind separator is 2.1cm, and the pipe diameter It is 4cm, and the tube length is 5.34cm.

[0029] According to the sieving analysis, the particle size of this batch of intermediate products is in the range of 1-0.5mm, mainly composed of plastic, Al, SiO ...

Abstract

The invention relates to an air separator for sucking granular materials by jet flow. The air separator is a reducing pipe and comprises a throat pipe (5), a reducing pipe air inlet (6), a nozzle (7) and a material outlet (8). The air separator is characterized in that negative pressure is generated by changing the flow velocity of air entering the separator, and materials are sucked into a pipeline from the throat pipe (5) positioned on a material inlet; and light materials are separated from heavier materials through granules by regulating the magnitude of air quantity. The invention realizes that pressured working fluids enter a jet cavity from an inlet of a jet flow adsorption feeder to form high-speed jet fluids, and pressure drop is generated through the high-speed jet fluids so that solid granular matters to be added are absorbed from a suction inlet and enter the pressured working fluids, therefore separation is realized; in addition, the air separation disclosed by the invention can be used for the air separation of the solid granular matters and also be used for a water treatment dosing system, thereby replacing the traditional pre-pumping dosing system and the traditional water jet dosing system.

Description

technical field [0001] The invention relates to a jet suction particle material sorter, which belongs to the technical field of material wind power sorting. Background technique [0002] Wind separation uses air as the separation medium, and the solid waste particles are separated according to density and particle size under the action of airflow. The existing air separation system is composed of fan, flow meter, pipeline and feed hopper installed on the pipeline. Due to the positive pressure on the pipeline, it is difficult for the material to be sent into the separation pipeline. [0003] Usually, in order to solve this problem, one is to install a screw feeder in the feed hopper to realize dynamic forced feeding. The second is to replace the fan with an induced draft fan and place it at the end of the pipeline to achieve negative pressure feeding. But both have drawbacks. The former requires the installation of a power system and has high requirements for the sealing ...
