Description
Technical field
The invention belongs to rotational moulding technical field, relate to a kind of without distortion oven door, particularly a kind of be applied on plastic rolling oven without distortion oven door.
Background technology
Baking oven is the obligato critical component of rotational molding machine.Because the quality (wall thickness is even, indeformable) of rotomoulded articles depends on the uniformity of Plastic Rolling Molds temperature.Therefore, rotational moulding is very high to the baking oven technical requirement of heating mould, summed up following some:
First require baking oven seal degree high, good heat insulating; Next is that oven ncavity is wanted fairing, favourable circulating air flow; 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 duct connection and reasonable arrangement of baking oven, is conducive to the each part of oven ncavity temperature even, has a narrow range of temperature; The 6th requires combustor to want energy completing combustion, pollutes baking oven and mould without residual oil/gas carbonization; 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 secondary charging function, so that rolling multiple-layer polychromatic is moulded goods, gives full play to effectiveness of rotational molding machine etc.
The indeformable requirement of oven door mentioned in requiring for the above-mentioned the 3rd, existing oven door is generally combined by left and right two fans, in mould enters into baking oven after, left and right two fans are drawn close and are made baking oven form a totally enclosed type heating space.Its oven door comprises three layers, and ectonexine is galvanized steel plain sheet, and middle that layer is rock cotton board, is equipped with by many longitudinal supports that form with many horizontal skeleton frameworks and supports between every layer.There is some problems: be mainly that its internal layer galvanized steel plain sheet of oven door and medial cradle are directly subject to high-temperature heating in baking oven, then cooling again, the result that it expands with heat and contract with cold repeatedly, oven door will be out of shape, plane is uneven, and sealing is poor, and the heat energy dissipation in baking oven comes to outside, cause energy waste, operating ambient temperature is high.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, thus proposed a kind of in baking oven heating work process, can not deform improve itself and baking oven body sealing be applied on plastic rolling oven without distortion oven door.
Object of the present invention can realize by following technical proposal: a kind of be applied on plastic rolling oven without distortion oven door, fanning door by left and right two combines, every fan door comprises three ply board, its inside and outside laminate is steel plate, its intermediate layer is thermal insulation thermal insulation board, between every laminate, be equipped with the support being formed by many longitudinal frameworks and the horizontal skeleton framework of Duo Gen, described three ply board is separately fixed on above-mentioned support, it is characterized in that: on the every skeleton of vertical and horizontal in described medial cradle, be provided with several C type nodes.
Every fan door comprises three ply board and two supports; thereby its outrigger there will not be the phenomenon of significantly expanding with heat and contract with cold to be difficult for deforming owing to being subject to the protection of thermal insulation thermal insulation board; but thereby its medial cradle can directly be subject to occurring heat expansion phenomenon from the high-temperature heating of baking oven; and the shrinkage phenomenon of oven door while opening; the result of repeatedly expanding with heat and contract with cold is easy to cause the distortion of its skeleton, and door is and then distortion also.Above-mentioned C type node structure can make skeleton in the time of heat expansion, and its elongation is absorbed by C type mouth, and when shrinkage, amount of contraction is compensated by C type mouth again, and its skeleton does not deform, thereby has ensured planarization and the sealing of oven door.
In above-mentioned a kind of be applied on plastic rolling oven without distortion oven door, described steel plate is galvanized steel plain sheet.
In above-mentioned a kind of be applied on plastic rolling oven without distortion oven door, described thermal insulation thermal insulation board is rock cotton board.
Rock cotton board can play the effect of insulation, makes the heat in baking oven be difficult for dispelling the heat away, improves Btu utilization, does not cause waste.
In above-mentioned a kind of be applied on plastic rolling oven without distortion oven door, described inner layer steel plate is flanging type porous galvanized steel plain sheet, outer layer plate is flanging type galvanized steel plain sheet.
In the time that inner layer steel plate expands with heat and contract with cold, the effect of C type node is played in the each hole on it, has ensured the indeformable of inner layer steel plate.
In above-mentioned a kind of be applied on plastic rolling oven without distortion oven door, between described medial cradle and outrigger, be connected with several C type nodes.
In above-mentioned a kind of be applied on plastic rolling oven without distortion oven door, on the inner side of described left and right two fan doors, be equipped with semi-circular recesses, on the sidewall of semi-circular recesses, be fixed with sealing gasket, in the time that left and right two fan doors close up, its two semicircular connected in star 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 is shut, just retaining ring is on baking oven body and be tightly connected for circular groove, and this sealing structure is good, prevents from running heat leak gas malarial region, causes heat energy to lose in a large number.
Compared with prior art, this has following several advantage without distortion oven door:
1, the loose structure of the C type node structure on the vertical and horizontal skeleton of its medial cradle and internal layer galvanized steel plain sheet has ensured that oven door is smooth indeformable, and effect of heat insulation is better;
2, the circular groove structure on oven door inner side has improved the heat sealability between oven door and baking oven body, seriously causes heat energy to run off in a large number thereby prevent from running heat leak gas;
3, this is simple in structure without distortion oven door, and result of use is good and the life-span is long.
