Embodiment 1

[0061] Such as figure 1 In the carbon black magnetic separation device shown, the vibrator 1 is connected to the vibrating bed 2 to drive the vibrating bed 2 to vibrate. The vibrating bed 2 sequentially includes a paving vibratory crushing section 21 and a magnetic separation section 22 along the moving direction of the material, and the magnetic separation assembly 3 is suspended above the magnetic separation section 22 for magnetically separating the scrap steel wire debris in the carbon black passing through the magnetic separation section 22 . In the direction of material movement, a plurality of material leveling parts 4 are arranged on the vibrating bed 2 . The structure of material paving part 4 is as figure 2 with image 3 shown.

[0062] The material paving piece includes a base 41, the bottom surface of the base 41 is a plane; the direction from front to back of the base is the direction of material movement; the view from front to back of the upper surface of t...

Embodiment 2

[0068] Such as Figure 4 The application process of the carbon black magnetic separation device 16 shown. Waste rubber tire enters feeder 13 through feeder 12, and feeder 13 throws waste rubber tire into pyrolysis reactor 11, and pyrolysis reactor 11 is heated by hot blast stove 10 delivery hot blast. The waste rubber tires undergo pyrolysis reaction in the pyrolysis reactor 11 to generate pyrolysis oil gas and pyrolysis carbon black. The pyrolysis oil gas is cooled by the condensing device to generate pyrolysis oil, and the pyrolysis carbon black containing 5% to 8% of scrap steel wire debris is continuously and quantitatively transported to the In the carbon black magnetic separation device 16, through the flattening, vibration crushing and magnetic separation of the carbon black magnetic separation device 16, scrap steel wire debris and carbon black particles are separated. Scrap steel wire debris is sent into the scrap steel wire debris collector 20, and the pure pyrolyt...

Abstract

The invention discloses a carbon black magnetic separation device. The carbon black magnetic separation device comprises a vibration exciter, a vibration bed and a magnetic separation assembly; the vibration exciter is connected with the vibration bed and is used for driving the vibration bed to vibrate; the vibration bed sequentially comprises a flattening and vibration crushing section and a magnetic separation section in the material movement direction; the magnetic separation assembly is arranged above the magnetic separation section in a suspended mode and used for conducting magnetic separation on waste steel wire chippings in carbon black passing through the magnetic separation section. At least one material paving piece is arranged on the vibration bed, the material paving piece comprises a base, and the bottom surface of the base is a plane; the view of the upper surface of the base from front to back is in a V shape, and the angle alpha of the V shape ranges from 120 degrees to 179 degrees. The included angle beta between the upper surface and the bottom surface is 5-20 degrees; and a corrugated plate is arranged on the base and is in a multi-stage sawtooth shape. According to the carbon black magnetic separation device, the screening rate of steel wire scraps is increased, the recycling rate of pyrolytic carbon black is increased, and generation of dust and secondary pollution to the environment are reduced.

Description

technical field [0001] The invention relates to a carbon black magnetic separation device. Background technique [0002] Waste rubber tires are industrial hazardous solid wastes, which are one of the harmful wastes that deteriorate the natural environment, destroy vegetation growth, affect human health, and endanger the earth's ecological environment. Waste rubber tires have strong heat resistance and mechanical resistance. Long-term open-air stacking not only takes up a lot of land, but also easily breeds mosquitoes and infectious diseases. It is easy to spontaneously ignite and cause fires under suitable temperature and dry climate conditions. [0003] The harmless and resourceful treatment of waste rubber tires is an important measure and means to reduce environmental pollution, maintain ecological balance, and maintain human health. At present, the main methods for the treatment and utilization of waste rubber tires in my country are: simple original shape utilization, ...
