Abstract
The invention discloses a quick-open adjustable air-tight door, relates to the technical field of cement equipment, in particular to a structure of an air-tight door, which comprises a bottom frame and a door closure, wherein sealing strips are arranged between the bottom frame and the door closure; two ears are connected with the bottom frame; two beams are arranged on the outer side of the door closure; two ends of each beam are respectively penetrated through the corresponding ears; the middle part of each beam is in threaded connection with a jackscrew; and the inner end of each jackscrew is in contact with the door closure. The sealing strips are arranged between the bottom frame and the door closure; by adjusting the jackscrews, as the jackscrews prop against the door closure and the sealing strips, the sealing effect and the sealing pressure can be adjusted; and the whole assembly structure of the air-tight door of the cement equipment is stable and reliable.
Description
Technical field
The present invention relates to the cement equipment technical field, particularly the structure of hermatic door.
Background technology
Hermatic door is as a kind of common cement equipment sealing device, and it is mainly used in preventing that the heat of cement equipment inside from distributing to external environment condition, and guarantees the relative sealing of furnace gas environment.And along with the improving constantly of working strength, people also have higher requirement for the serviceability of cement equipment hermatic door.
Present existing cement equipment hermatic door is hinged by hinge between its door-plate and the doorframe usually, and is closed mutually between door-plate and the doorframe in the use procedure, to guarantee the relative airtight of furnace gas environment and external environment condition.When needs externally between environment and furnace inner environment during convey materials, again door-plate is opened, in order to material is carried.
In the routine use process, although above-mentioned cement equipment hermatic door can satisfy the basic need of work of cement equipment, but owing to be the hinge mounted relation between its door-plate and doorframe, under the closure state, thrust between door-plate and doorframe is inhomogeneous, structural reliability after assembling is finished is relatively poor, very easily the slit appears in the joint portion between door-plate and doorframe, cause producing between furnace inner environment and external environment condition the gas exchange, cause the furnace gas environment to be destroyed, thereby have a strong impact on the normal production and processing work of cement equipment.
Therefore, how to make the thrust distribution of cement equipment hermatic door more even, and make its sealing effectiveness be more preferably the important technological problems that those skilled in the art need to solve at present.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide that a kind of thrust is evenly distributed, sealing effectiveness is opened soon preferably adjustable dense and sealed up a door.
The object of the present invention is achieved like this: open soon adjustable dense and seal up a door, comprise underframe and door closure, between underframe and door closure, sealing strip is set, connect two ears or side handles of a utensil on the described underframe, two crossbeams of the arranged outside of door closure, the two ends of each crossbeam are set in respectively in the corresponding ears or side handles of a utensil, the middle part of each crossbeam jackscrew that is threaded respectively, and the inner of every jackscrew contacts respectively setting with door closure.
The nut that is threaded respectively on the every jackscrew of the present invention, each nut is separately positioned on the outside of crossbeam, between each nut and the corresponding crossbeam pad is set respectively.
Be provided with sealing strip between underframe of the present invention and the door closure, by adjusting jackscrew, because jackscrew withstands door closure and sealing strip, can regulate sealing effectiveness, sealing load, the integral installation distribution structure of cement equipment hermatic door is reliable and stable.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 be among Fig. 1 A-A to view.
The specific embodiment
As shown in Figure 1, 2, seal up a door for opening soon adjustable dense, comprise underframe 7 and door closure 5, between underframe 7 and door closure 5, sealing strip 8 is set, connect two ears or side handles of a utensil 6 on the underframe 7, two crossbeams 4 of the arranged outside of door closure 5, the two ends of each crossbeam 4 are set in respectively in the corresponding ears or side handles of a utensil 6, the middle part of each crossbeam 4 jackscrew 1 that is threaded respectively, the inner of every jackscrew 1 contacts setting with door closure 5 respectively.The nut 2 that is threaded respectively on the every jackscrew 1, each nut 2 is separately positioned on the outside of crossbeam 4, between each nut 2 and the corresponding crossbeam 4 pad 3 is set respectively.
Claims (2)
1. opening soon adjustable dense seals up a door, comprise underframe and door closure, between underframe and door closure, sealing strip is set, it is characterized in that: connect two ears or side handles of a utensil on the described underframe, two crossbeams of the arranged outside of door closure, the two ends of each crossbeam are set in respectively in the corresponding ears or side handles of a utensil, the middle part of each crossbeam jackscrew that is threaded respectively, and the inner of every jackscrew contacts respectively setting with door closure.
2. the adjustable dense of opening soon according to claim 1 is sealed up a door, and it is characterized in that: the nut that is threaded respectively on the every jackscrew, each nut is separately positioned on the outside of crossbeam, between each nut and the corresponding crossbeam pad is set respectively.
