Detailed Description
The utility model is described in further detail below with reference to the drawings and examples.
As shown in fig. 1-2, a laboratory small gypsum waste flotation device comprises a floating material receiving groove 1, wherein a water inlet 6 and a discharge hole 7 are respectively arranged at the top end and the bottom end of the side wall of the floating material receiving groove 1, a raw material groove 2 is fixed in the middle of the groove bottom of the floating material receiving groove 1, a conical microporous aeration disc 3 is arranged at the bottom of the raw material groove 2, and a flotation screen 8 fixed by a spring pressing buckle 9 is arranged at the middle upper part of the raw material groove 2; the top of the conical microporous aeration disc 3 is connected with one end of a pneumatic connecting pipe 4 penetrating through the center of the flotation screen 8, the other end of the pneumatic connecting pipe 4 is connected with a small air pump, and an air flowmeter 5 is arranged on the pneumatic connecting pipe 4.
A Teflon coating is sprayed in the floating material receiving groove 1, and the floating material receiving groove 1 is made of stainless steel or plastic with low adhesive force.
The aperture of the flotation screen 8 is 100-300 mu m, and the flotation screen 8 is made of stainless steel so as to prevent lighter and obvious particles in the slurry from floating out along with the selected matters.
The raw material tank 2 is made of plastic with low adhesive force, and the diameter of the raw material tank 2 is 1/2-2/3 of the diameter of the tank bottom of the floating material receiving tank 1.
The aeration aperture of the conical microporous aeration disc 3 is 10-150 mu m, so that slurry is reduced to be deposited on the surface of the conical microporous aeration disc 3, and then the aeration holes are blocked.
The working principle of the utility model is as follows:
When the gypsum waste is required to be pretreated, a flotation sieve 8 is opened, dilute sulfuric acid solution and a flotation agent are poured into the raw material tank 2, then a gas flowmeter 5 is opened, a small air pump is started to ventilate until a conical microporous aeration disc 3 generates foam, phosphogypsum waste is added into the raw material tank 2, and the flotation sieve 8 is buckled; because the conical microporous aeration disc 3 adopts the conical structure, the foam quantity in the middle of the raw material trough 2 is larger, so that lighter ash and lighter carbon simple substances and other lighter floats in phosphogypsum can be pushed to move to the periphery independently, a Teflon coating layer is sprayed in the floating material receiving trough 1, lighter ash and lighter carbon simple substances and other lighter floats in phosphogypsum can overflow into the floating material receiving trough 1, and meanwhile, the water inlet 6 and the discharge hole 7 on the side wall of the floating material receiving trough 1 realize flushing and collecting of lighter ash and lighter carbon simple substances and other lighter floats in phosphogypsum.
