Description
Technical field:
This utility model relates to a kind of roller kilns, particularly relates to a kind of rare earth fuel gas table kiln.
Background technology:
Rare earth fuel gas table kiln is the equipment of industry baked for producing Rare earth oxide polishing powder, in the process of industry baked for producing Rare earth oxide polishing powder, raw material is through oven for drying or directly sends into fuel gas table kiln from kiln hood, after sequentially passing through preheating and roasting, finally obtain earth oxide product at kiln tail.
There are the following problems for the method for existing industry baked for producing Rare earth oxide polishing powder:
First, raw material needs to be equipped with substantial amounts of oven equipment and steam boiler and substantial amounts of steam heating pipeline in the drying operation before entering kiln, need to consume substantial amounts of manpower and materials, and production efficiency is low and takies big quantity space.
Second, the waste heat of existing fuel gas table kiln is directly discharged into air after treatment, it does not have well utilize, and causes the waste of resource.
Utility model content:
The purpose of this utility model is to provide a kind of waste heat that can make roller kilns and is fully used, and raw material can be made again to obtain a kind of rare earth fuel gas table kiln of fully drying before burning till.
The purpose of this utility model is implemented by following technical scheme, and a kind of rare earth fuel gas table kiln, it includes kiln body, and in described kiln body, horizontal Tile is provided with high temperature resistant roll shaft；Vertically being provided with insulated wall in described kiln body, described kiln body is divided into preheating section and the section of burning till by described insulated wall；Being arranged over dust collecting box at described preheating section, the air inlet of described dust collecting box is connected by fume pipe with described kiln body, and the air vent of described dust collecting box is connected with acid gas system；The two side of described preheating section is provided with pre-hot blast nozzle along described kiln body length direction is uniformly through；Along the described kiln body length direction uniformly through nozzles that are provided with on the two side of the described section of burning till front end, the air inlet of described nozzles is connected with combustion-supporting airduct and cartridge respectively；The through waste heat airduct that is provided with in top in the described section of burning till rear end, described waste heat airduct is through with described pre-hot blast nozzle to be connected.
Further, described insulated wall includes insulated wall and lower insulated wall, described upper insulated wall is vertically fixed in the described kiln body above described high temperature resistant roll shaft, described lower insulated wall is fixed in the described kiln body below described upper insulated wall, and the upper end of described lower insulated wall is concordant with the lower end of described high temperature resistant roll shaft.
Further, described upper insulated wall is prefabricated ceramic fibre insulated wall, and described lower insulated wall is light fire brick insulated wall.
Advantage of the present utility model:
1, this utility model one rare earth fuel gas table kiln is by waste heat recovery, rare earths material is carried out pre-hot work, shorten the rare earths material baking time in the section of burning till, and the rare earth dust produced when preheating is collected by dust box, sour gas is used for antacid by acid gas systematic collection, can significantly energy-saving and emission-reduction, effectively reduce production cost, improve work efficiency.
2, this utility model one rare earth fuel gas table kiln is provided with insulated wall in kiln body, and when can effectively hinder rare earths material to preheat, moisture, sour gas and part rare earth dust are to the diffusion of the section of burning till, and improve the work efficiency of the section of burning till.
Accompanying drawing illustrates:
Fig. 1 is 1 one kinds of rare earth fuel gas table kiln schematic diagrams of embodiment.
In figure: kiln body 1, preheating section 1-1, the section of burning till 1-2, high temperature resistant roll shaft 2, insulated wall 3, prefabricated ceramic fibre insulated wall 3-1, light fire brick insulated wall 3-2, dust collecting box 4, fume pipe 5, pre-hot blast nozzle 6, nozzles 7, combustion-supporting airduct 8, cartridge 9, waste heat airduct 10.
