Abstract
The utility model discloses a heating device for multilayer winding process of tube materials with walls in polyethylene winding structures, which comprises a main air barrel and a flaming nozzle. The design key includes that a fire retaining partition board is arranged at the front end of the main air barrel, an air discharge plate and a rear end cap are disposed at the rear end of the main air barrel, a fire shading cover is welded on the air discharge plate, the rear end cap is connected with a gas pipeline and an air inlet pipeline, the gas pipeline is led into the fire shading cover via a center hole on the rear end cap, the flaming nozzle is disposed at the end of the gas pipeline, and an igniter is arranged on the wall, which corresponds to the front end of the flaming nozzle, of the main air barrel. The heating device is simple and practical in structure, easy in assembling, disassembling and repair and convenient in operation. The heating device is applied to preheating multilayer winding framework tubes of the tube materials with walls in polyethylene winding structures, and the prepared tube materials has fine splicing property and high ring stiffness.
Description
Technical field
The utility model relates to a kind of heater, specifically a kind of heater that is particularly useful for wall tube of large aperture framework-tube polyethylene winding structure multi-lay winding technology.
Background technology
Wall tube of large aperture framework-tube polyethylene winding structure normally twines the big skeleton control of one deck again by one deck ossiculum frame pipe (or the flat band of one deck) and forms fully.When twining the big skeleton pipe of the second layer, need carry out preheating to the ossiculum frame pipe (or flat band) of ground floor, so that there is certain thickness soften layer on its surface, could guarantee that thus second layer skeleton pipe and ground floor skeleton pipe (or flat band) can bond together securely.At present, when carrying out preheating, normally adopting the cartridge heater that is tied with electric furnace heating wire to heat the ossiculum frame pipe (or flat band) of ground floor.The problem that this device exists is that (soften layer thickness generally can only reach 1～2mm) to the heating weak effect, thereby the bonding fastness of casing play and casing play is poor, and the product ring stiffness is low, interlayer is easy to crack.The electric furnace heating wire of cartridge heater easily blows in addition, keeps in repair time-consuming again.
The utility model content
The purpose of this utility model to provide exactly a kind of easy to use, heating is effective, especially is applicable to the heater of polyethylene spirally enwound structure-wall tubular product multi-lay winding technology.
The purpose of this utility model is achieved in that
The heater that is used for polyethylene spirally enwound structure-wall tubular product multi-lay winding technology provided by the utility model includes main wind tube, bocca, and its design main points are that the front end of described main wind tube is provided with retaining fire screen plate; The rear end of main wind tube is provided with loose wind sheet and rear end cap; Be welded with on the diffusing wind sheet and hide the fire cover; Be connected with gas pipeline and intake stack on the rear end cap; Gas pipeline feeds by the centre bore on the rear end cap and hides in the fire cover; The termination of gas pipeline has been provided with bocca; With the corresponding main air barrel of bocca front end on be provided with igniter.
The utility model in use, after combustion gas enters screening fire cover in the main wind tube by gas pipeline, open the intake valve in the gas pipeline, air valve in igniter and the intake stack, this moment, bocca was lighted, under the effect of the wind sheet that looses, the air-flow that enters the main wind tube from intake stack is scattered in whole screening fire cover and the main wind tube, formed good combustion-supporting environment thus on the one hand, combustion air current has blowed to heat energy the front end of main wind tube on the other hand, this moment, under the effect of retaining fire screen plate, the flame of extension is intercepted in the main wind tube, and heat energy is then discharged slowly.Both guaranteed thus that the heat energy of discharging was enough to the skeleton pipe is being carried out preheating, the while has also been avoided naked light to directly act on the high-density polyethylene material surface and has caused soften layer to be carbonized.
The utility model is simple and practical, is easy to dismounting, maintenance, is convenient to operation.Its hot blast temperature that blows out can reach 420 ℃～600 ℃, and soften layer thickness can reach 3～4mm, therefore adopts the utility model that polyethylene spirally enwound structure-wall tubular product multi-lay winding skeleton pipe is carried out preheating, and its prepared tubing adhesive property is good, the ring stiffness height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
As shown in Figure 1, the utility model includes main wind tube 2, bocca 8.Be welded with retaining fire screen plate 1 on main wind tube 2 front inner wall; The rear end of main wind tube 2 is provided with loose wind sheet 4 and rear end cap 5; Be welded with the screening fire cover 3 of band mesh on the diffusing wind sheet 4; Be connected with gas pipeline 6 and intake stack 7 on the rear end cap 5, gas pipeline 6 feeds by the centre bore on the rear end cap 5 and hides in the fire cover 3; The termination of gas pipeline 6 is provided with bocca 8; With corresponding main wind tube 2 walls of bocca 8 front ends on be provided with igniter 9.
In order to strengthen the thermal effect that adds of this device, the refractory plate of retaining fire screen plate 1 select tape mesh wherein.
In order to improve effect, the wind sheet 4 that looses is preferably arranged according to the circumference five equilibrium, and the cross section of the blade face of its each diffusing wind sheet and main wind tube 2 is the miter angle setting, and the longitudinal terminal surface of each diffusing wind sheet 4 is provided with scarf 10.So after the air of intake stack enters screening fire cover 3 and main wind tube 2, the wind sheet that promptly loose is dispersed into the helical form air-flow, make thus combustion gas and air can more abundant mixing in the combustion chamber, burning, and flame is pivotably sprayed from hide fire cover 3 surface holes, by the wind in the main wind tube 2 it is taken out of again, form effectively work hot blast thus.
