Rotary kiln roasting structure and roasting process thereof

Abstract

The invention discloses a rotary kiln roasting structure and a roasting process thereof. The rotary kiln roasting structure comprises a bottom plate, wherein a rotary kiln body which is obliquely arranged is arranged above the bottom plate; a first motor is arranged at one side below the rotary kiln body; the output end of the first motor is fixedly connected with a drive gear; the middle part ofthe rotary kiln body is fixedly connected with a driven gear; one end of the rotary kiln body is connected with a coal injection mechanism; the coal injection mechanism comprises a combustor; one endof the rotary kiln body is rotatably connected with the middle part of the combustor; one end, far away from the rotary kiln body, of the combustor is fixedly connected with a connecting tube; the drive gear is engaged with the driven gear, the driven gear rotates, and the rotary kiln body fixedly connected with the driven gear rotates; the rotary kiln body is obliquely arranged, and the rotary kiln body rotates, so that materials move from the head end of the rotary kiln body to one end of the combustor while rotating; the closer the materials are to the combustor, the higher the temperatureis; and the materials are gradually roasted by flame sprayed out from a burner uniformly, so that the roasting effect is better, and roasting energy consumption is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of production equipment, and in particular relates to a rotary kiln roasting structure and a roasting process thereof. Background technique: [0002] In the production of sand making, it is necessary to put the sand making raw materials into the kiln for roasting, and the powdery raw materials are roasted at high temperature in the kiln to make clinker, so that the sand making with stable size and increased strength can be obtained. The production of cement sand not only reduces the production of waste, but also saves coal powder and resources. [0003] Under the existing technology, generally use the dry kiln flue to roast the raw material for sand making, the roasting effect is poor, and the energy consumption for smelting is high; the flame injection range of the burner is insufficient, the temperature is not uniform enough, and the degree of sand making reduction is poor; the amount of coal powder is no...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rotary kiln roasting structure and its roasting process, by setting the driving gear, driven gear, runner, swirl plate and vibration mechanism, to solve the problem of using the drying kiln flue proposed in the above background technology. Roasting the sand-making raw materials has poor roasting effect and high energy consumption for smelting; the flame injection range of the burner is insufficient, the temperature is not uniform enough, and the degree of sand-making reduction is poor; the amount of coal powder cannot be quantitatively controlled, resulting in the inability to control the intensity of the roasting flame question
