The specific embodiment
As shown in Figure 1, the internal return device mainly is made up of parts such as feeder 8, material returning device 6, blender 4, movable supporting legs 5, fixed supporting legs 7.
Feeder 8 is positioned at the appropriate location of cylindrical shell 3, form by parts such as side plate 18, grid 19, flights 20, be connected with cylindrical shell 3 with backing plate II21 by the backing plate I21 that is welded on the cylinder inboard wall, as shown in Figure 3, it mainly is the material that is used for taking up in the cylindrical shell 3, it is sent in the material returning device 6, and grid 19 can prevent that the material of bulk from entering material returning device 6, in order to avoid stop up; Material returning device 6 is made up of housing I15, housing II15, adapter sleeve 13, stiffener I12, stiffener II12, spiral 14, gag lever post 9 etc., it mainly is that the material that feeder 8 is sent to is back to the device head, with the mixing of materials of sending into by feed auger 2, connect with adapter sleeve 13 between housing I15, housing II15, the housing III15, spiral 14 is fixed in the housing, gag lever post 9 is connected on the housing I15, and be connected with spiral 14, to prevent spiral 14 axial displacements, stiffener I12 and stiffener II12 weld with housing III15 and housing I15 respectively; Blender 4 is made up of housing III15, inside spin 10, the material that is used for mixed material and is returned by material returning device 6; Fixed supporting leg 7 is positioned at the position near feeder 8, and movable supporting legs 5 is by three uniform being supported between rotary reaction furnace cylindrical shell 3 and the internal return device case of every circle, as shown in Figure 2, can slide damage equipment when avoiding the elongation of cylindrical shell 3 and internal return device expanded by heating between movable supporting legs 5 and the cylindrical shell 3 relatively.
Operation principle
Select best returning charge amount by test, make raw material, returning charge and the concentrated sulfuric acid form suitable solid-to-liquid ratio, disperse easily to form the reaction mass of thickness state effectively, make reactant be loose condition (of surface), the sticking wall that reduces thickness state material contacts with cylinder inboard wall with strong acid media, thereby prevents to tie wall and mitigate corrosion; Thereby the high temperature returning charge of carrying a large amount of heats simultaneously can improve the temperature of charge initiation reaction rapidly and carry out fast, improves reaction efficiency and heat utilization efficiency.
The course of work of this device is: the feeder 8 that is arranged in reacting furnace cylindrical shell 3 appropriate locations will be taken up at the generation material that cylindrical shell is piled up certain altitude and send into material returning device 6, material returning device 6 is back to the device head by spiral 14 with material when rotating with equipment barrel 3, in blender 4, fall into cylindrical shell 3 front ends after the Forced Mixing with the material of sending into by feed auger conveyer 2, with the concentrated sulfuric acid hybrid reaction that is entered by escape pipe 1, the silicon tetrafluoride gas of generation is discharged from escape pipe 1 and is entered the postorder processing then.When the elongation of cylindrical shell 3 beginning expanded by heating, the internal return device slides backward under the drive of feeder 8 at fixed supporting leg 7, and along with the expansion that progressively raises of the temperature of internal return device, movable supporting legs 5 drives the internal return device again to front slide.
