Abstract
The utility model discloses a device for preheating a barrel body. The device is specially used for automatically heating the barrel body and comprises a bracket and two copper cambered ventilating pipes fixed on the bracket, wherein two ends of each ventilating pipe are closed; a plurality of transitional pipes communicated with the interiors of the two ventilating pipes are arranged between the two ventilating pipes; a plurality of air injection pipes communicated with the interiors and the exteriors of the ventilating pipes are respectively arranged on the inner cambered sides of the two ventilating pipes; and an air inlet pipe communicated with the interior and the exterior of one of the ventilating pipes is arranged on one of the ventilating pipes. The device has the advantages that the cambered ventilating pipes are wrapped on the outer side of the barrel body; the openings of the air injection pipes are aligned with the outer side of the barrel body and heat the barrel body by flames; and an aim of automatically heating the barrel body is fulfilled.
Description
Technical field
The utility model relates to a kind of cylindrical shell preheating device.
Background technology
Along with the development of chemical industry, the equipment of chemical industry equipment industry also develops to maximization, large-tonnage direction gradually.In the boilers and pressure vessel industry, run into some medium plates through regular meeting, because steel plate is thicker, its weldability is relatively poor, guarantees welding quality so need on technology, carry out some necessary methods.The medium plate of some carbon steels, steel alloy and low-temperature steel need carry out preheating and postheating in welding, guarantees its welding quality.Usually to be the staff add thermal-flame and heat through hand-held way, and labour intensity is big, but also can not guarantee the stability of preheating, can the butt welded seam quality impact.
The utility model content
The utility model technical problem to be solved is: a kind of cylindrical shell cylindrical shell preheating device of heating automatically that is specifically designed to is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of cylindrical shell preheating device; Comprise support and the breather pipe that is fixed on two arcs made of copper on the support, the closed at both ends of breather pipe is provided with some and is communicated with the inner transition conduit of two breather pipes between two breather pipes; Be respectively arranged with some on the two breather pipe arc inboards and be communicated with inner outside with it air jet pipe of breather pipe, wherein a breather pipe is provided with and is communicated with inner outside with it air inlet pipe of breather pipe.
The beneficial effect of the utility model is: utilize the arc breather pipe to be wrapped in the cylindrical shell outside, the air jet pipe critical point is aimed at the cylindrical shell outside and is carried out flame heat, thereby reaches the purpose that automatically cylindrical shell is heated.
Description of drawings
Fig. 1 is the front view of the utility model cylindrical shell preheating device;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, first breather pipe, 2, second breather pipe, 3, transition conduit, 4, air jet pipe, 5, air inlet pipe, 6, support.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
Like Fig. 1, shown in Figure 2; The described cylindrical shell preheating device of the utility model; The breather pipe---first breather pipe 1 and second breather pipe 2 that comprise two arcs made of copper on support 6 and the support 6; The two ends of first breather pipe 1 and second breather pipe 2 are sealed respectively, and first breather pipe 1 and 2 of second breather pipes are provided with the some transition conduit 3 that are communicated with first breather pipe 1 and second breather pipe, 2 inside, and the concrete quantity of transition conduit 3 is decided according to actual conditions.Be respectively arranged with some on first breather pipe 1 and second breather pipe, the 2 arc inboards and be communicated with first breather pipe 1, inner outside with it air jet pipe 4 of second breather pipe 2 respectively, the concrete quantity of air jet pipe 4 is decided according to actual conditions.First breather pipe 1 is provided with and is communicated with first breather pipe, the 1 inside air inlet pipe 5 outside with it, in actual production, also can air inlet pipe 5 be arranged on second breather pipe 2 certainly.
The course of work of the utility model is: like Fig. 1, shown in Figure 2; First breather pipe 1 and second breather pipe 2 are wrapped in the cylindrical shell outside; The position that cylindrical shell need heat is aimed in the outlet of air jet pipe 4; Then combustion gas is passed in first breather pipe 1 and second breather pipe 2 from air inlet pipe 5, combustion gas from the ejection of air jet pipe 4 mouths of pipe, is lighted this combustion gas and just can have been heated cylinder body outer wall at last.Because breather pipe is made of copper, plasticity is good, can change the radian of breather pipe according to the size of cylindrical shell, and convenient distance of regulating between air jet pipe 4 and the cylinder body outer wall guarantees the effect that heats.The utility model is simple in structure, and is easy to operate, reduced operating personnel's working strength.
