Description
Technical field
The utility model relates to a kind of wireway for external heat type rotary furnace.
Background technology
Whether directly contact with material according to heat-carrying agent, rotary furnace, external heat type rotary furnace is normally at rotary furnace cylindrical shell arranged outside chuck if can be divided into two kinds of internal heat type and external-heats, and in chuck, carry high warm flue gas to provide heat to reaction in furnace or dry run.At some industrial circle, usually utilize external heat type rotary furnace to heat some material and make it to occur pyrolytic reaction, detailed process is: material is sent in rotary furnace by dispenser from burner, the gas producing after material reaction is extracted out from burner by wireway, and reacted material is discharged along with the body of heater of rotation moves to stove tail.
Because material easily produces a large amount of dust in fill process, simultaneously, the lifting blade arranging for augmentation of heat transfer also very easily produces a large amount of dust in lifting process, therefore, rotary furnace in process of production, is often full of a large amount of dust in stove, the wireway that is arranged on burner usually stops up because sucking a large amount of dust, make the rotary furnace cannot normal operating, therefore, prevent that rotary furnace wireway dust from stopping up is one of key factor that can many rotary furnaces continuous service.
Summary of the invention
Hold susceptible to plugging defect in order to overcome the known wireway for external heat type rotary furnace, the utility model provides a kind of wireway for external heat type rotary furnace, and this wireway can significantly reduce the dust content in gas bleeding, prevents the generation of stopping state.
The technical solution adopted in the utility model is: a kind of wireway for external heat type rotary furnace, this wireway comprises fixing straight tube and rotation Taper Pipe, wireway end bleeding point is positioned at or approaches the concentrated conversion zone of rotary furnace, fixing straight tube is connected by bellows with the quiet end cap of burner, the end of fixing straight tube extend in rotary furnace, the front end sleeve of rotation Taper Pipe is on fixing straight tube end, rotation Taper Pipe is fixedly linked by retaining collar and the support bar and the rotary furnace cylinder inboard wall that are uniformly distributed along the circumference, between between adjacent two joint rotation Taper Pipes, be separated with distance, there is slip collar at two joint rotation Taper Pipe junction covers, slip collar is fixedly linked by the support bar and the rotary furnace cylindrical shell that are uniformly distributed along the circumference, rotating cone inside pipe wall is provided with helical blade, the direction of rotation of the rotation direction of helical blade and rotary furnace cylindrical shell is consistent, the large end of rotation Taper Pipe is bleeding point.
Advantage of the present utility model: (1) adopts conical pipe with the helical blade major part as wireway, wireway extend into the concentrated conversion zone of rotary furnace inside simultaneously, make coal gas and the tar gas impurity content of extraction minimum, dust accumulation in wireway is minimum, prevent the generation of wireway stopping state, be conducive to follow-up technological operation simultaneously; (2) rotation Taper Pipe is connected by plug-in type with fixing straight tube, between rotation Taper Pipe, connect by sleeve pipe, two rotations keep at a certain distance away between Taper Pipes, this connection and fixed form had both solved the Rotation of rotary furnace, have solved again wireway and be subject to the axial expansion problem of high temperature.

The specific embodiment
As shown in Figures 1 and 2, external heat type rotary furnace is mainly made up of feeder 1, wireway 2, cylindrical shell 3, external jacket 4 and discharger 5.Wireway 2 is made up of a fixing straight tube 6 and some joints rotation Taper Pipe 9, wireway 2 built-in lengths are determined according to rotary furnace cylindrical shell length and reaction in furnace situation, preferred version: wireway 2 end bleeding points are positioned at or approach the concentrated conversion zone 14 of rotary furnace, coal gas and tar gas are concentrated the region of separating out in a large number.
As shown in Figure 2, the fixing straight tube 6 of wireway 2 is connected by bellows 13 with the quiet end cap 7 of burner, and extend in rotary furnace, and the front inner diameter of rotation Taper Pipe 9 is more bigger than fixing straight tube 6 external diameters, and be enclosed within on fixing straight tube 6, fixing straight tube 6 inserts the interior certain distance of rotation Taper Pipe 9.
As shown in Figures 2 and 3, one end of each joint rotation Taper Pipe 9 is fixed support, be fixed on the center of rotary furnace cylindrical shell 3 by a circle retaining collar 12 and multiple support bars 8 of being uniformly distributed along the circumference, retaining collar 12 rotates with support bar 8, support bar 8 and the equal firm welding of rotary furnace cylindrical shell 3 inwall, rotation Taper Pipe 9 with rotation Taper Pipe 9 outer walls, retaining collar 12 together with rotary furnace cylindrical shell 3.
As shown in Figures 2 and 4, between adjacent two joint rotation Taper Pipes 9, keep at a certain distance away, at the bigger slip collar 10 of two joint rotation Taper Pipe 9 junction cover one circle internal diameters ratio rotation Taper Pipe 9 external diameters, slip collar 10 is connected with rotary furnace cylindrical shell 3 by the multiple support bars 8 that are uniformly distributed along the circumference, slip collar 10 and support bar 8, support bar 8 and the equal firm welding of rotary furnace cylindrical shell 3 inwall, rotation Taper Pipe 9 does not weld with slip collar 10, because rotation Taper Pipe 9 can be at the interior free-extension of slip collar 10, so end is the sliding support of rotation Taper Pipe 9.
As shown in Figure 2, on rotation Taper Pipe 9 inwalls, be provided with helical blade 11, the direction of rotation of the rotation direction of helical blade 11 and rotary furnace cylindrical shell 3 is consistent, while rotation with the rotation Taper Pipe 9 of helical blade 11, the dust entering on a small quantity in wireway can be discharged in rotary furnace, again in addition, the large end of rotation Taper Pipe 9 is as bleeding point, can reduce the gas flow rates at bleeding point place, be conducive to dust sedimentation before entering wireway 2, reduce the Dust Capacity that enters wireway 2.
