Anti-return feeding device for low-all-vanadium roasting of rotary kiln and using method of anti-return feeding device

Abstract

The invention discloses an anti-return feeding device for low-all-vanadium roasting of a rotary kiln and a using method of the anti-return feeding device. The anti-return feeding device comprises a bottom box, wherein a feeding box is arranged at the top of the bottom box; a No. 2 ventilation rod is rotationally connected to the interior of the feeding box; a rotating mechanism is arranged on one side of the feeding box, and connected with the No. 2 ventilation rod; a filtering mechanism is arranged at the top of the bottom box; the filtering mechanism is connected with the rotating mechanism; and a feeding mechanism is arranged in the bottom box. The anti-return feeding device has the beneficial effects that a No. 1 belt wheel and a No. 2 belt wheel are additionally arranged, so that simultaneous rotation of a half gear and a No. 2 gear is achieved; crushing rollers are additionally arranged, so that raw materials are crushed through the crushing rollers; a No. 4 ventilation rod and a No. 3 ventilation rod are additionally arranged, so that anti-blocking treatment on internal materials is achieved; the filtering mechanism is additionally arranged, so that filtering treatment on external air is achieved; and the half gear and a rack are additionally arranged, so that the half gear drives a connecting frame to move in a reciprocating mode through the rack.

Description

technical field [0001] The invention relates to the technical field of feeding devices, in particular to an anti-return feeding device for low-full vanadium roasting of a rotary kiln and a use method thereof. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel-iron ore; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasting of chromi...

Problems solved by technology

Lime kiln (i.e. active lime kiln) is used for roasting active lime and lightly burned dolomite used in iron and steel plants and ferroalloy plants. The existing roasting needs to be treated with feeding, but the existing feeding device is not convenient for anti-blocking treatment of raw materials. It is easy to cause the bottom to be blocked, and the existing feeding device will cause reverse material when conveying, which reduces the efficiency of conveying
