The seal arrangement of pyrolysis rotating drum of the present invention, is provided with multiple labyrinths sheet in powder groove, the gas inside and outside rotating drum is better blocked, goes for the rotary seal at pyrolysis of coal reactor content inlet/outlet two ends.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of seal arrangement of pyrolysis rotating drum of the present invention.
Reference character in figure is expressed as:
1-stationary magazine creel; 2-threaded ring; The positive left-hand thread stud of 3-; 4-pyrolysis rotating drum; 5-sleeve; 6-heat-resistant fibers; 7-labyrinth sheet; 8-powder groove; 9-powder bucket; 10-powder level sensor.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 shows a kind of embodiment of seal arrangement of pyrolysis rotating drum of the present invention, and as shown in Figure 1, a kind of seal arrangement of pyrolysis rotating drum, comprising: sleeve 5 and powder bucket 9.Be provided with powder level sensor 10 in described powder bucket 9, be used for judging the position in storehouse of powder.Described sleeve 5 is connected with stationary magazine creel 1, is sleeved on the outside of described rotating drum 4 one end.Described powder bucket 9 is arranged on the top of described sleeve 5, and the lower end of powder bucket 9 is connected with described sleeve 5.High temperature resistant powder has been taken up in described powder bucket 9.Described high temperature resistant powder can be emery or magnetic powder.
In the seal arrangement of pyrolysis rotating drum of the present invention, in described sleeve 5, be provided with powder groove 8; The both sides of described powder groove 8 are provided with the envelope powder device for stoping high temperature resistant powder to flow out described sleeve 5.This envelope powder device comprises: the high-temperature resistant fiber layer 6 of described powder groove 8 both sides; And be arranged at outside described high-temperature resistant fiber layer 6, the locking device of described sleeve 5 end positions.Described locking device comprises: the threaded ring 2 being positioned at described sleeve 5 end positions; And threaded ring 2 described with two is connected respectively, is used for coordinating the positive left-hand thread stud 3 compressing described high-temperature resistant fiber layer 6 with described threaded ring 2.In two threaded rings 2, one is left-handed thread trim ring, and another is right-handed thread trim ring.Just heat-resistant fibers 6 can be compressed by rotating two threaded rings 2, and then by the high temperature resistant powder compacting in powder groove 8, become and more not easily breathe freely.
In the seal arrangement of pyrolysis rotating drum of the present invention, powder groove 8 is one and is arranged between sleeve 5 and rotating drum 4, is full of the groove of high temperature resistant powder.This powder groove 8 is that a top is connected with described powder bucket 9 lower end, and remaining part is closed by the high-temperature resistant fiber layer 6 of sleeve 5 and rotating drum 4 and both sides, the annular groove of upper end open.Be provided with spaced in described powder groove 8, the ring-type labyrinth sheet 7 be connected with described rotating drum with described sleeve 5 respectively.Specifically, have the labyrinth sheet 7 of half to be vertically connected on the outer ancient piece of jade, round, flat and with a hole in its centre of rotating drum 4, the labyrinth sheet 7 of half is vertically connected on an interior ancient piece of jade, round, flat and with a hole in its centre for sleeve 5 in addition, and the vertical cross-section plane of the plane residing for labyrinth sheet 7 and described rotating drum 4 annular is parallel to each other.Labyrinth sheet 7 on an interior ancient piece of jade, round, flat and with a hole in its centre for the outer ancient piece of jade, round, flat and with a hole in its centre of rotating drum 4 and sleeve 5 is staggered, so the cross section of multiple labyrinths sheet 7 as shown in Figure 1 defines labyrinth shape.Filled full between adjacent labyrinth sheet 7 by high temperature resistant powder, gas needs the zigzag path turnover rotating drum 4 walking around labyrinth formation.So the multiple labyrinths sheet be provided with in powder groove 8, makes the gas inside and outside rotating drum 4 better be blocked, thus makes seal arrangement of the present invention go for the rotary seal at pyrolysis of coal reactor content inlet/outlet two ends.
In the course of the work, rotating drum 4 carries out rotary rolling to the seal arrangement of pyrolysis rotating drum of the present invention, and the ring-type labyrinth sheet 7 be connected with rotating drum 4 outer wall is also along with rotating drum 4 rolls.And stationary magazine creel 1 and sleeve 5 keep motionless, the ring-type labyrinth sheet 7 be connected with described sleeve 5 also keeps motionless.The labyrinth sheet 7 that the labyrinth sheet 7 that rotating drum 4 outer wall connects is connected with sleeve 5 changing of the relative positions mutually.In powder bucket 9 and annular powder groove 8, be filled with high temperature resistant powder, these high temperature resistant powder hinder the free-flow of air-flow inside and outside rotating drum 4.
Carry out in the process of rotary rolling at rotating drum 4, the gap between the high-temperature resistant fiber layer 6 of the high temperature resistant powder in powder groove 8 constantly along both sides and stationary magazine creel 1 outer wall outwardly, and is flowed out by the position of the threaded ring 2 being positioned at sleeve 5 two ends.So the high temperature resistant powder in powder bucket 9 can constantly reduce.Once powder level sensor 10 reports that the position in storehouse of powder is in low level, then need to add high temperature resistant powder to powder bucket 9.
In addition, the distance between adjacent ring-type labyrinth sheet 7, can consider the thermal expansion factor of rotating drum 4 material, mutually collides, contacts and be as the criterion can not there is labyrinth sheet in heating and cooling process.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
