Example Embodiment

[0035]Example 1

[0036]Seefigure 1 ,Figure 3-5This embodiment provides a rotary kiln roasting structure and its sintering process, including a bottom plate 1, a rotary kiln body 2 is arranged above the bottom plate 1, and a first motor 4 is arranged on the lower side of the rotary kiln body 2. The output end of the rotary kiln body 2 is fixedly connected with a driving gear 5, the middle of the rotary kiln body 2 is fixedly connected with a driven gear 6, the upper middle of the bottom plate 1 is fixedly connected with a fixed plate 3, and one side of the fixed plate 3 is fixedly connected with a first motor 4 through a fixed seat. The upper side of the driving gear 5 is in meshing connection with the driven gear 6. First, the first motor 4 is turned on. When the output shaft of the first motor 4 rotates, the driving gear 5 is driven to rotate. Because the driving gear 5 and the driven gear 6 mesh, the driven gear The gear 6 rotates to drive the rotary kiln body 2 fixedly connected wi...

[0038]Example 2

[0039]Refer tofigure 2 ,Figure 6 , Further improvements made on the basis of Example 1:

[0040]A discharge hopper 13 is provided below one end of the rotary kiln body 2 near the burner 71, and the rotary kiln body 2 is provided with a discharge hole relative to the discharge hopper 13. The material moves to the discharge hole of the rotary kiln body 2, and is discharged from the outlet due to its own gravity. When the material hole falls, the material falls into the lower opposite discharge hopper 13. A filter screen 15 is arranged in the middle of the discharge hopper 13, and the filter screen 15 is fixedly connected with side frames 17 on four sides. The material falls on the filter screen 15 in the discharge hopper 13. The filter screen 15 plays a role of sieving. Materials with qualified size are discharged through the filter screen 15. The material larger than the pores of the filter screen 15 remains on the filter screen 15. A vibration mechanism 16 is provided un...

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...
