Description
Technical field
The utility model belongs to the rotational moulding technical field, relates to a kind of nothing distortion oven door, particularly a kind of nothing distortion oven door that is applied on the rotational moulding baking oven.
Background technology
Baking oven is the obligato critical component of rotational moulding machine.The uniformity that depends on the Plastic Rolling Molds temperature because of the quality (wall thickness is even, indeformable) of rotomoulded articles.Therefore, rotational moulding is very high to the baking oven specification requirement of heating mould, summarize get up to have following some:
At first require baking oven seal degree height, good heat insulating; Next is that oven ncavity is wanted fairing, the flowing of favourable circulating air; The 3rd requires oven door indeformable, avoids heat-energy losses; The 4th requires combination seal between oven door and body, air tight; The 5th requires the hot air circulation air channel connection and reasonable arrangement of baking oven, and it is even to help each part temperature of oven ncavity, has a narrow range of temperature; The 6th requires combustor to want energy completing combustion, no residual oil/gas carbon pollution baking oven and mould; The 7th requires pressure fan fan blade dynamic balance performance good, and noiseless is beneficial to environmental protection; The 8th requires oven ncavity dischargeable capacity utilization rate to reach more than 95%; The 9th requires baking oven to possess the secondary charging function, so that the rolling multiple-layer polychromatic is moulded goods, gives full play to effectiveness of rotational moulding machine or the like.
The indeformable requirement of mentioning in requiring at the above-mentioned the 3rd of oven door, existing oven door generally by about two fans combine, in mould enters into baking oven after, about two fans draw close and make baking oven form a totally enclosed type heating space.Its oven door comprises three layers, and ectonexine is a galvanized steel plain sheet, and middle that layer is a rock cotton board, is equipped with between every layer by many vertical supports that form with many horizontal skeleton frameworks and supports.There is some problems: be that mainly its internal layer galvanized steel plain sheet of oven door and medial cradle directly are subjected to high-temperature heating in the baking oven, cooling again then, the result that it expands with heat and contract with cold repeatedly, oven door will be out of shape, the plane is uneven, and sealing is poor, and the heat energy dissipation in the baking oven comes to the outside, cause energy waste, the operating ambient temperature height.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, improves the nothing distortion oven door on the rotational moulding baking oven of being applied to of itself and baking oven body sealing thereby proposed a kind of can not deforming in baking oven heating work process.
The purpose of this utility model can realize by following technical proposal: a kind of nothing distortion oven door that is applied on the rotational moulding baking oven, by about two fan doors combine, every fan door comprises three ply board, its inside and outside laminate is a steel plate, its intermediate layer is a thermal insulation thermal insulation board, be equipped with the support that forms by many vertical skeletons and the horizontal skeleton framework of Duo Gen between every laminate, described three ply board is separately fixed on the above-mentioned support, it is characterized in that: be provided with several C type nodes on every skeleton of the vertical and horizontal in the described medial cradle.
Every fan door comprises three ply board and two supports; phenomenon is difficult for deforming thereby its outrigger is not because significantly expanding with heat and contract with cold can appear in the protection that is subjected to thermal insulation thermal insulation board; but its medial cradle can directly be subjected to thereby the heat expansion phenomenon occurring from the high temperature heating of baking oven; and the shrinkage phenomenon of oven door when opening; the result of expanding with heat and contract with cold repeatedly is easy to cause the distortion of its skeleton, and door is and then distortion also.Above-mentioned C type node structure can so that skeleton when heat expansion, its elongation is absorbed by C type mouth, during shrinkage, by the compensation of C type mouth, its skeleton does not deform amount of contraction, thereby has guaranteed the planarization and the sealing of oven door again.
A kind of nothing distortion oven door that is applied on the rotational moulding baking oven in above-mentioned, described steel plate is a galvanized steel plain sheet.
A kind of nothing distortion oven door that is applied on the rotational moulding baking oven in above-mentioned, described thermal insulation thermal insulation board is a rock cotton board.
Rock cotton board can play the effect of insulation, makes that the heat in the baking oven is difficult for dispelling the heat away, improves Btu utilization, does not cause waste.
A kind of nothing distortion oven door that is applied on the rotational moulding baking oven in above-mentioned, described inner layer steel plate is a flanging type porous galvanized steel plain sheet, outer layer plate is a flanging type galvanized steel plain sheet.
When inner layer steel plate expanded with heat and contract with cold, the effect of C type node was all played in each hole on it, had guaranteed the indeformable of inner layer steel plate.
A kind of nothing distortion oven door that is applied on the rotational moulding baking oven is connected with several C type nodes between described medial cradle and the outrigger in above-mentioned.
A kind of nothing distortion oven door that is applied on the rotational moulding baking oven in above-mentioned, be equipped with semi-circular recesses on the inboard of two fan doors about described, be fixed with sealing gasket on the sidewall of semi-circular recesses, when about two fan doors when closing up, its two semi-circular recesses forms a circular groove and is tightly connected by sealing gasket and baking oven body.
Circular groove is more bigger than baking oven body cylindrical, and when oven door was shut, just retaining ring was on the baking oven body and be tightly connected for circular groove, and this sealing structure is good, prevents to run heat leak gas malarial region, causes heat energy to lose in a large number.
Compared with prior art, this nothing distortion oven door has following several advantage:
1, the loose structure of C type node structure on the vertical and horizontal skeleton of its medial cradle and internal layer galvanized steel plain sheet has guaranteed that oven door is smooth indeformable, and effect of heat insulation is better;
2, the circular groove structure on the oven door inboard has improved the heat seal between oven door and the baking oven body, seriously causes heat energy to run off in a large number thereby prevent to run heat leak gas;
3, this nothing distortion oven door is simple in structure, and result of use is good and the life-span is long.
