Quick-open adjustable air-tight door

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 [0001] The invention relates to the technical field of cement equipment, in particular to the structure of a hermetic door. Background technique [0002] As a common cement equipment sealing device, the airtight door is mainly used to prevent the heat inside the cement equipment from dissipating to the external environment, and to ensure the relative sealing of the gas environment in the furnace. With the continuous improvement of work intensity, people have also put forward higher requirements for the performance of cement equipment airtight doors. [0003] At present, the airtight door of cement equipment is usually hinged between the door panel and the door frame. During use, the door panel and the door frame are closed to ensure the relative airtightness of the gas environment in the furnace and the external environment. When it is necessary to transport materials between the external environment and the furnace environment, the door panel is opened to t...

AI Technical Summary

Problems solved by technology

[0004] In daily use, although the cement equipment sealing door mentioned above can meet the basic working needs of cement equipment, due to the hinged assembly relationship between the door panel and the door frame, in the closed state, the pressing force between the door panel and the door frame is uneven, and the assembly is completed. The reliability of the final structure is poor, and it is very easy to have a gap at the junction between the door panel and the door frame, resulting in gas exchange between the furnace environment and the external environment, resulting in damage to the gas environment in the furnace, which seriously affects the normal production of cement equipment processing work
