Technical field
The utility model relates to a kind of fast sealing flap that is used for the reduction and distillation furnace inlet and outlet of the reduction and distillation furnace inlet and outlet that titanium sponge produces, and belongs to the technical field of sealing technology of reduction and distillation furnace inlet and outlet.
Background technology
At present, last one arts demand of titanium sponge production uses reduction and distillation furnace.At reduction phase,, on reduction and distillation furnace, need to stay and establish some inlet and outlets and reduce this section temperature with air-cooled form for preventing the conversion zone temperature overheating; But arrive distillation during the stage, the necessary strict sealing of these inlet and outlets, the anti-vacuum of extraction adapts to the interior vacuum requirement of distiller in the stove so that make.Therefore, periodic frequent switching of inlet and outlet lid is one of reduction and distillation furnace operation characteristic.In the prior art surplus in the of ten inlet and outlet lid all adopt flange to connect, the defective of this structure is: 1) dismounting of numerous flap and installation had both strengthened labor intensity of operating personnel, expend time in again simultaneously, cause the prolongation of explained hereafter time, influence production capacity; 2) just finished the reduction distillation device of the heat of titanium sponge reduction,, must be incubated, and the time that the installation of flap needs is long, thereby need expend more electric energy and be incubated in order to keep essential temperature of distillation stage; 3) flange seal place temperature is higher, and the work condition environment of vacuum rubber sealing ring is abominable, and sealing reliability is relatively poor.Obviously, the sealing means of the inlet and outlet of existing reduction and distillation furnace still is not ideal enough.
The utility model content
The purpose of this utility model is: the fast sealing flap of the reduction and distillation furnace inlet and outlet of the reduction and distillation furnace inlet and outlet that provide that a kind of structure simple structure, sealing property are stable, long service life, electrical heat energy utilization rate height and operation and maintenance cost is all lower, and to overcome the deficiencies in the prior art.
The utility model is achieved in that it comprises the furnace shell that is provided with the reduction and distillation furnace inner lining of furnace, inlet and outlet place on furnace shell is welded with the steel pipe that this inlet and outlet can be covered, interior capping is housed on the inlet and outlet that steel pipe covers, port at steel pipe is fixed with base, rubber seal is arranged on the base, on furnace shell, the both sides up and down of steel pipe are fixed with fixed supported slab and following fixed supported slab respectively, be connected with crossbeam by rotating shaft on the fixed supported slab down, on crossbeam, be provided with screwed hole, in the screwed hole of crossbeam, rotary screw is housed, but gland is connected the front end of rotary screw and gland on rubber seal, is connected with by bearing pin on last fixed supported slab and can entangles the pullover of crossbeam.
In order to reach better sealing effectiveness, on base, be provided with groove, rubber seal is arranged in the groove of base.
Rubber seal preferably adopts the vacuum rubber sealing ring.
In order to make effect of heat insulation and sealing effectiveness better, in the interior capping of being adorned on the inlet and outlet that steel pipe covers, be wound with the refractory fibre rope.
Convenient in order to use, in interior capping, be provided with handle, on rotary screw, be provided with handle.
Owing to adopted technique scheme, the utility model is by being provided with steel pipe, interior capping and the mode of rubber seal and gland being set at steel tube end part again, make the space that forms a closed heat insulation at reduction and distillation furnace inlet and outlet place, this can not only be avoided rubber seal to suffer too high temperature effectively and damage, and can also seal effectively with heat insulation.Therefore, the utility model compared with prior art, the utility model has not only that construction is simple, easy to operate rapidly, the reliable and stable advantage of sealing property, but also have long service life, and can make that product quality and production capacity are guaranteed, advantage such as electrical heat energy utilization rate height, operation and maintenance cost are low.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
Embodiment of the present utility model: during making, a steel pipe 3 that this inlet and outlet can be covered is welded at each inlet and outlet place on the existing furnace shell 15 that is provided with reduction and distillation furnace inner lining of furnace 16 respectively, capping 1 on the inlet and outlet that steel pipe 3 covers, loading onto, interior capping 1 can be adopted and water the material feeding structure, its THICKNESS CONTROL is between 150～250mm, weight should be less than 14kg, in order to reach better sealing and effect of heat insulation, can in the interior capping of being adorned on the inlet and outlet that steel pipe 3 covers 1, twine refractory fibre rope 2; Base 4 on the port welding of steel pipe 3 is fixing, and on base 4, produce a loop sealed groove, rubber seal 5 is placed in the groove of base 4, better in order to make sealing effectiveness, rubber seal 5 can adopt the vacuum rubber sealing ring finished product of selling on the market; Then on the furnace shell 15, the dual-side up and down of each steel pipe 3 welds respectively and fixes fixed supported slab 13 and following fixed supported slab 7 on one, connecting a crossbeam 9 by rotating shaft 8 on the fixed supported slab 7 down, and on crossbeam 9, produce a screwed hole, in the screwed hole of crossbeam 9, load onto a rotary screw 10, the screw thread of the screwed hole of crossbeam 9 and rotary screw 10 is preferably pressed the specification of Tr24 and made; Then gland 6 is movably connected in the front end of rotary screw 10, but make its at gland under the drive of rotary screw 10 on rubber seal 5, the boss of convex circulus and the annular seal groove fit on the base 4 are arranged preferably making an astragal on the gland 6, can guarantee that like this this sealing back, place pressure that bears is not less than 0.1Mpa; During making, should notice guaranteeing that weld seam is tight between steel pipe 3 and furnace shell 15 and the base 4, make it can bear pressure and be not less than 0.1Mpa; On last fixed supported slab 13, connect one and can entangle pullover 12 of crossbeam 9 by bearing pin 14; Convenient in order to use, can a handle be installed in interior capping 1, a handle 11 is installed on rotary screw 10.
