Problems solved by technology

Once some hardened dust is shaken off by vibration, it will immediately leave the dynamic rotation balance of the fan, and then generate strong vibration, which may cause serious personnel and equipment safety accidents

Embodiment Construction

[0036] Now in conjunction with accompanying drawing, the present invention is described in further detail.

[0037] Such as figure 1 , figure 2 , image 3 , Figure 4 ,with Figure 5The shown manganese processing rotary kiln system is heated by a gas furnace and the induced draft fan does not accumulate dust. It includes a rotary kiln 1, which is arranged obliquely, and has a built-in burner 6. The burner 6 is connected to the air control valve 19 and the gas control valve 20; The high end of the kiln is equipped with an air locker 11 for feeding, and is connected to the cyclone dust collector 8 through the wing segment 15 and the air pipe 17. The cyclone dust collector 8 is connected to the induced draft fan A, and the exhaust port of the induced draft fan A is connected to the bag filter 10. The bottom of 8 is connected to the air locker, and there is a dust collection bucket 23 under the air locker; fins 14 are arranged inside the fin section 15, a cover tube 16 is arr...

Abstract

The invention discloses a manganese processing rotary kiln system with a gas furnace supplying heat and a draught fan being free of dust accumulation. A rotary kiln is arranged in an inclined mode. A combustor is arranged in the rotary kiln and connected with an air control valve and a gas control valve. An air lock is arranged at the higher end of the rotary kiln for feeding and connected with a dust remover through a fin section and an air pipe. A cover cylinder is arranged outside the fin section, a sleeve type air heat exchanger is arranged outside the air pipe, and the cover cylinder is connected with the gas control valve and the air control valve after being joined with a lower air suction port of the air heat exchanger. The draught fan is of a structure with blades being in a reverse drop shape and a back plate being in a butterfly shape. A convex refractory plate is arranged in the rotary kiln. Through the convex refractory plate, the heat transfer area of the rotary kiln is increased, material stirring is promoted, and heat efficiency is easily improved; through the fin section and the air heat exchanger, tail heat is utilized, and combustion is facilitated; through shock chilling liquid, the environmental protection pressure of production liquid expansion is effectively relieved; because the draught fan is free of dust accumulation, safety accidents are effectively eradicated. The manganese processing rotary kiln system is especially suitable for manganese ore firing processing and has broad application prospects.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a manganese processing rotary kiln system for heating by a gas furnace and no dust accumulation by an induced draft fan. Background technique [0002] Due to its strong adaptability, low operating cost and high reliability, the rotary kiln is one of the main preferred equipment for mineral batching, pelletizing, reaction and drying, especially suitable for the processing and burning of manganese ore. During the working process, the rotary kiln needs to consume fuel to maintain a suitable high temperature in the kiln. Therefore, the exhaust gas discharged from the rotary kiln contains a lot of heat energy and dust. It is necessary to purify the exhaust gas and recover the exhaust heat to achieve energy saving and emission reduction. [0003] The rotary kiln is generally cylindrical, so the heat transfer area between the material and the kiln body is very small, resulting in low thermal efficiency....
