Description
Technical field
the utility model relates to the effective curing oven of a kind of plastic coated composite steel.
Background technology
apply in the process of plastic material in steel tube surface, at first utilize heating furnace that steel pipe is heated to 260-320 ℃, then use the surfaces externally and internally coating plastic powder of blowing device to steel pipe, recycling solidification equipment or curing oven are coated in steel tube surface by plastic powders.After steel tube surface coating plastic powder, temperature is more than 180 ℃, and needs to solidify more than 15 minutes, just can make the surface of steel pipe form plastic coating, so existing curing oven adopts the mode of fixing steel pipe that plastic coating is curing usually.Although this kind of curing mode also can be made quality plastic coated composite steel pipe preferably, but when the steel pipe after solidifying is taken out from curing oven, the temperature of invar pipe is higher on the one hand, for quality for larger steel pipe, take out difficulty relatively, topmost problem is, no matter adopt the artificial or mechanical steel pipe of getting in curing oven, all need to adopt the clamping steel pipe it could be taken out, and the clamping steel pipe can cause to the plastic coating in the position of clamping damage, could form qualified plastic coated composite steel pipe after only having the position excision that the steel pipe plastic coating is damaged, so, the mode of this kind of hardened plastic coating can improve cost of manufacture.
the name of No. 202591089U, Chinese patent bulletin is called mode that heating furnace that " for the steel pipe rotary conveying device on the plastic-coated steel heating furnace " propose can make steel pipe can automatically pass in and out in it and is heated, and what automatically pass in and out the heating furnace employing is track and chain, vertically be provided with two rows for stirring the fork of steel pipe on the carrier bar of chain, and the upper surface of chain is lower than the upper surface of track, and the upper surface of the high errant in upper end of fork, utilize in the process of this conveying device heating steel pipe, at first steel pipe is placed in orbit, by fork fixing on carrier bar, steel pipe is pushed in heating furnace, and steel pipe is heated by mobile mode.Although utilize this conveying device serially steel pipe to be heated, and can improve output, but because fork is fixed on carrier bar, carrier bar is in the process of rotating, and fork promotes steel pipe from track, so that steel pipe moves in heating furnace, and can produce relative large resistance between steel pipe and fixing track, and utilize fork to promote to scribble on surface the steel pipe of plastic layer, fork can destroy plastic coating, so the mode of this kind of hardened plastic coating can improve cost of manufacture.
Summary of the invention
task of the present utility model is to propose a kind of mode of direct support and Automatic-falling of utilizing to solve the curing oven that the pipe plastic coating layer has the plastic coated composite steel pipe of damaged location problem.
the effective curing oven of the plastic coated composite steel that the utility model proposes comprises insulation furnace shell and conveyer, and wherein, the both sides of insulation furnace shell are respectively arranged with horizontal long through groove, in the insulation furnace shell, air-heater are installed; Conveyer comprises that the two ends by stent support that are arranged on holding furnace shell-side face are equipped with the turning cylinder of profile of tooth driving wheel and are arranged on the fixed axis that the two ends by stent support that are incubated the furnace shell opposite side are equipped with the profile of tooth driven pulley, and at the endless chain be equipped with between the profile of tooth driving wheel of the same side and profile of tooth driven pulley in long through groove enters the insulation furnace shell, and be provided with the protuberance for supporting steel pipe on endless chain.
the below at described conveyer middle part is equipped with driving machine, initiatively toothed wheel is installed on the output shaft of driving machine, and is fixed with the driven toothed wheel on turning cylinder, between active toothed wheel and driven toothed wheel, annular drive chain is installed.
what described air-heater adopted is axial flow blower.
distance between described adjacent two protuberances is greater than the diameter with this device heating steel pipe.The central region of described protuberance is provided with arc-shaped recess section.
the curing oven of the plastic coated composite steel pipe that the utility model proposes adopts the protuberance on endless chain directly to support and scribble the steel pipe of plastic layer and make it can automatically pass in and out curing oven, it is not clamped, so, can not cause damage to the coating layer of steel pipe, and then can reduce the cost of manufacture of plastic coated composite steel pipe.
the accompanying drawing explanation
accompanying drawing 1 is the surface structure schematic diagram of an embodiment of curing oven device of the plastic coated composite steel pipe that proposes of the utility model;
accompanying drawing 2 is cross-sectional view of Fig. 1.
the specific embodiment
referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the surface structure of an embodiment of device of the movable type heating steel pipe that the utility model proposes.This device comprises insulation furnace shell 1, conveyer 2, driving machine 3 and the receiving element 4 that is arranged on conveyer 2 front ends.
the outer surface of the insulation furnace shell 1 provided in the present embodiment and the furnace chamber of inner surface are cuboid, and the both sides at insulation furnace shell 1 are respectively arranged with horizontal long through groove 11, also be provided with the groove 12 that allows endless chain 26 to pass in the both sides of this long through groove 11, and in insulation furnace shell 1, air-heater is installed, this air-heater can adopt axial fan, because air-heater all belongs to common practise as axial fan etc., so, its concrete structure do not provided in figure.
turning cylinder 22 is to be driven by driving machine 3, this driving machine 3 comprises that motor 31 is equipped with initiatively toothed wheel 32 with being arranged on motor 31 output shafts, and be fixed with driven toothed wheel 33 on turning cylinder 22, between active toothed wheel 32 and driven toothed wheel 33, annular drive chain 34 is installed.
in the process heated at the steel pipe to applying plastic material, at first the temperature of utilizing air-heater will be incubated in furnace shell 1 is heated to 120-150 ℃, then utilizing motor 31 to drive annular drive chain 34 rotates, to drive turning cylinder 22 to rotate and drive endless chain 26, rotate, the steel pipe of coated plastic material is placed on protuberance 27, so that steel pipe little by little enters in insulation furnace shell 1, it is carried out to hot blast and heat.
