Description
Technical field
The utility model relates to a kind of body heat-insulating and sealing structure, for drying plant, belongs to the hermatic door technical field.
Background technology
Dryer is a kind of equipment that utilizes heat and wind energy to dry, and the area coverage of door body reaches more than 60% of whole dryer surface area, and the effect of heat insulation that improves the door body will reduce energy consumption greatly, reduce indoor environment temperature, and comfortable working environment is provided.Drying plant often is used in feedstuff industry in addition, and in case, dust is many.The sealing performance quality of door body has determined that the direct outer discharge of heat is how many, has also determined whether to have dust and has released in casing.
Traditional door body heat-insulating and sealing structure comprises doorframe, door leaf and door hinge, door leaf comprises external door panel and door backboard, the drive end of door hinge is fixedly connected with the outer wall of external door panel, the door backboard is positioned at the external door panel inboard, the edge of door backboard is fitted on the inwall of external door panel, the middle part of door backboard is to the projecting inward formation heat insulation cavity of door, in heat insulation cavity, be filled with adiabator layer, the edge of external door panel forms bound edge to doorframe direction flanging, the sealed groove that between bound edge and door backboard, Formation cross-section takes the shape of the letter U, be embedded with sealing ring in sealed groove.When door leaf cut out, sealing ring is pressed on doorframe realized sealing.
There is following weak point in traditional door body heat-insulating and sealing structure:
1. at first compressed near the sealing ring of door hinge, the space of sealing circle periphery is smaller, and when door leaf did not also cut out fully, sealing ring was just fully compressed, add that the compressible amount of original sealing ring is less, easily cause between sealing ring and doorframe poorly sealed.
2. the compressible amount of sealing ring is little, but needs to obtain better sealing, just need to apply larger coupling mechanism force and make the rubber wriggling obtain larger deflection, and the needed thrust that causes closing the door is very large; And traditional door body structure does not have to hold the more required space of large deformation of rubber, cause rubber to be difficult to further distortion compression, cause a body just can close under larger coupling mechanism force.
3. directly towards the high-temperature area of box house, door backboard edge directly contacts with external door panel again the door backboard, forms the direct heat transfer between metal, and heat output is large, is unfavorable for the heat insulation of a body.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of door body heat-insulating and sealing structure of good seal performance is provided.
For solving above technical problem, a kind of body heat-insulating and sealing structure of the present utility model, comprise doorframe, door leaf and door hinge, described door leaf comprises external door panel and door backboard, the drive end of described door hinge is fixedly connected with the outer wall of described external door panel, described door backboard is positioned at described external door panel inboard, the edge of described door backboard is fitted on the inwall of described external door panel, the middle part of described door backboard is to the projecting inward formation heat insulation cavity of door, in described heat insulation cavity, be filled with adiabator layer, the edge of described external door panel forms bound edge to described doorframe direction flanging, the sealed groove that between described bound edge and described door backboard, Formation cross-section takes the shape of the letter U, in described sealed groove, be embedded with sealing ring, position near described sealed groove on described door backboard is provided with bending part, described bending part away from the position of described sealed groove to the one side bending of described adiabator layer place, described sealing ring is that hollow structure and cavity are positioned at the side near doorframe.
With respect to prior art, the utility model has been obtained following beneficial effect: the position near sealed groove on the door backboard is provided with bending part, to sealed ring deformation, provide space, the more aximal deformation value that can hold sealing ring, sealing ring is that hollow structure makes the deformability of sealing ring better, and the size of cavity can be done greatlyr to obtain larger distortion, and the required pressure of Reducing distortion.
As preferred version of the present utility model, the middle part of described door backboard is coated with internal hilar plate on the side plane in door, is provided with the silica-gel heat-insulating pad plate between described internal hilar plate and described backboard.By the high-temperature area of internal hilar plate towards box house, the direct heat that the silica-gel heat-insulating pad plate resistance has been broken between internal hilar plate and door backboard is conducted, and has reduced the heat output in the unit interval, has improved effect of heat insulation.
