Abstract
A kind of seal closure of rotary furnace, including the double storehouse of rotating cylinder, movable sealing and sealing, wherein, sealing double storehouse and include intermediate bin and gas-tight silo, movable sealing is arranged on rotating cylinder entrance point, intermediate bin front end is connected with movable sealing, intermediate bin rear end is connected with gas-tight silo, and is provided with closed air vent on intermediate bin, and gas-tight silo is arranged on the rotating cylinder port of export, for the outlet of rotating cylinder being closed, between gas-tight silo and intermediate bin, it is provided with cover body sealing ring simultaneously.The present invention uses double-chamber type structure, when rotary furnace can not enter air, is closed by intermediate bin.When rotary furnace needs air, then open intermediate bin so that material is not easily accessible movable sealing, both can guarantee that the sealing of movable sealing, be avoided that again when being passed through air in rotary furnace stove, the phenomenon that movable sealing is stuck occurs, simple in construction, practical.
Description
Technical field
The present invention relates to sealing device technical field, particularly relate to the seal closure of a kind of rotary furnace.
Background technology
Chinese patent: publication number: CN103603955A discloses the moving seal connection device of a kind of rotary furnace, in reality
Rotary furnace can be solved during use well and can not enter air such as roasting indigo plant tungsten, the problem of purple tungsten, but when needs are passed through
During air such as roasting Huang tungsten, operator's practices well is to open the window in discharge cover, but when opening window, owing to returning
Converter body temperature is high, and the air outside body of heater supplements and enters, and will form air-flow, thus occur raising in causing rotary furnace boiler tube
Dirt, in even there is the movable sealing that material enters into rotary furnace, in turn results in movable sealing stuck.
Summary of the invention
Technical problem solved by the invention is to provide the seal closure of a kind of rotary furnace, to solve in above-mentioned background technology
Shortcoming.
Technical problem solved by the invention realizes by the following technical solutions:
The seal closure of a kind of rotary furnace, including the double storehouse of rotating cylinder, movable sealing and sealing, wherein, seals double storehouse and includes intermediate bin
With gas-tight silo, movable sealing is arranged on rotating cylinder entrance point, and intermediate bin front end is connected with movable sealing, intermediate bin rear end and gas-tight silo
Connect, and on intermediate bin, be provided with closed air vent, and gas-tight silo is arranged on the rotating cylinder port of export, for turning round
The outlet of cylinder is closed, and is provided with cover body sealing ring between gas-tight silo and intermediate bin simultaneously.
In the present invention, movable sealing is provided with movable sealing sealing ring.
In the present invention, intermediate bin two ends are installed and are respectively arranged with sealing ring.
In the present invention, air vent is symmetrical set in the middle part of intermediate bin up and down.
In the present invention, air vent intermediate bin arranged is closed by shrouding.
In the present invention, when air can not be entered in rotating cylinder, use shrouding by the exhaust close of intermediate bin, move close
Envelope work；When needing in rotating cylinder into air, by the Exhaust Open of intermediate bin so that communicate with the external world in intermediate bin,
Because intermediate bin pressure is more than the pressure within rotating cylinder, simultaneously because be provided with cover body sealing in the middle of gas-tight silo and intermediate bin
Circle so that material is difficult to escape, even if there being a small amount of material to escape, owing to rear shape is opened in the setting symmetrical above and below of the air vent of intermediate bin
Become, at air-flow, and movable sealing, movable sealing sealing ring is installed so that material is difficult to arrive inside movable sealing, can only be from intermediate bin
Lower exhaust port is discharged.
Beneficial effect: the present invention uses double-chamber type structure, when rotary furnace can not enter air, closes intermediate bin.When returning
When converter needs air, then open intermediate bin so that material is not easily accessible movable sealing, both can guarantee that the sealing of movable sealing, again can
Avoid when being passed through air in rotary furnace stove, the phenomenon that movable sealing is stuck occurs, simple in construction, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of presently preferred embodiments of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
See the seal closure of a kind of rotary furnace of Fig. 1, including rotating cylinder 1, movable sealing 2, intermediate bin 3, air vent 4, cover
Body sealing ring 5, gas-tight silo 6 and movable sealing sealing ring 7.
In the present embodiment, rotating cylinder 1 being provided with movable sealing 2, movable sealing sealing ring 7 is arranged in movable sealing 2, in
Between front end, storehouse 3 be connected with movable sealing 2, intermediate bin 3 rear end is connected with gas-tight silo 6, and the row of being provided with symmetrical above and below in the middle part of intermediate bin 3
QI KOU 4, the outlet of rotating cylinder 1 is closed by gas-tight silo 6, is provided with cover body sealing ring 5 between gas-tight silo 6 and intermediate bin 3 simultaneously,
Intermediate bin 3 two ends are provided with sealing ring.
When air can not be entered in rotating cylinder 1, shrouding is used to be closed by two air vents 4 of intermediate bin 3, movable sealing 2
Work；When needing into air in rotating cylinder 1, two air vents 4 of intermediate bin 3 are opened so that with extraneous in intermediate bin 3
Communicate, because intermediate bin 3 pressure is more than the pressure within rotating cylinder 1, simultaneously because be provided with in the middle of gas-tight silo 6 and intermediate bin 3
Cover body sealing ring 5 so that material is difficult to escape, even if there being a small amount of material to escape, owing to shape opened by 3 two air vents 4 of intermediate bin
Become, at air-flow and movable sealing 2, movable sealing sealing ring 7 is installed so that it is internal that material is difficult to arrive movable sealing 2, can only be from intermediate bin
The lower exhaust port 4 of 3 is discharged.
