Abstract
The utility model relates to an uniform heating auxiliary device, in particular to an uniform heating auxiliary device for container whole heat treatment, which comprises an umbrella shaped shield, aflow guide tube, and a supporting rod, wherein the umbrella shaped shield adopts a horn shape, the big mouth of the horn faces downward, and an air hole penetrating the wall of the umbrella shaped shield is arranged on the umbrella shaped shield; the flow guide tube is a bent hollow tube, one end of the flow guide tube is connected with the air hole of the umbrella shaped shield, the other end thereof is communicated with the low-temperature space in the container; both the flow guide tube and the umbrella shaped shield are fixedly connected by the supporting rod in the container. In the utility model, the umbrella shaped shield is arranged above the heating nozzle, therefore when the flame and the smoke encounter the umbrella shaped shield, a part of the high-temperature airflow is prevented from going and enabled to flow downward to heat the lower part of the container, the flow guide tube communicated and connected to the top part of the umbrella shaped shield moves a part of the high-temperature airflow to other low-temperature spaces in the container, so as to change the original direction of the high-temperature flame, thereby realizing the uniform heating of each part thereof.
Description
Technical field
The utility model relates to a kind of heating supplementary unit, relates in particular to a kind of heat treated even heating supplementary unit of integral container that is used for.
Background technology
POST WELD HEAT TREATMENT OF ENTIRE is the critical process that pressurized vessel is made, purpose is to eliminate the stress that produces in container assembling and the welding process, thermal treatment normally is carried to integral container in the process furnace heats by certain heating and cooling technology, owing to be subjected to objective restriction of depositing condition, for the big volume pressure container or the overlength container of assembly welding at the scene, this method is also inapplicable.
Carry out the container of complete heat treatment for the mode that can't adopt the stove internal heating, usually adopt inner fuel oil method to carry out complete heat treatment, the tank body that promptly utilizes container self is as combustion chamber, the part pore of tank body is ejected into combustion oil and air mixture in the jar as oil and gas import burns, by the control warming and cooling rate, be heated to certain temperature, reach the purpose that eliminates stress equally.
When carrying out inner fuel oil method complete heat treatment, combustion oil and air mixture are by being provided with nozzle on the pore under the container, fuel vapor sprays into the internal tank burning from nozzle from bottom to top, combustion flame be not subjected under the external intervention situation, flame vertically upward, hot gas flow is to upper punch, can cause like this locating high-temperature zone of formation, wall of container district directly over the nozzle, and the nozzle left and right sides forms a cold zone owing to flame is difficult for arriving, it is inhomogeneous like this container inner wall to be heated, the even homothermic condition that requires when not reaching container thermal treatment.Therefore be necessary to do further improvement at prior art, so that the internal tank thermal-flame air-flow heat transfer of evenly circulating during thermal treatment, uniform heat distribution.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, even heating supplementary unit that can make internal tank thermal-flame air-flow evenly circulate and conduct heat.
To achieve these goals, the scheme that the utility model adopts is: a kind of heat treated even heating supplementary unit of integral container that is used for, it is characterized in that: it includes umbrella hood, thrust-augmenting nozzle, support bar, it is horn-like that umbrella hood is, big mouthful of loudspeaker downwards, and the umbrella hood top offers the pore that runs through a umbrella hood wall thickness; Thrust-augmenting nozzle is the open tube of bending, and thrust-augmenting nozzle one end links to each other with the pore of umbrella hood, and the other end leads to the cold zone in the container; Thrust-augmenting nozzle and umbrella hood are fixedly connected in the container by support bar.
The pore thread connection of described thrust-augmenting nozzle and umbrella hood.
The utility model adopts the mode that umbrella hood is set directly over heated nozzle, after making flame and flue gas run into umbrella hood, part high temperature gas flow is kept off returning to flow downward to the container lower heating, the umbrella hood top is connected thrust-augmenting nozzle with other cold zone in a part of high temperature gas flow guiding container, thereby change the original trend of thermal-flame, reach the purpose of each position even heating.
Description of drawings
Fig. 1 is the utility model example structure sectional view;
Description of symbols among the figure, the 1-umbrella hood; 2-thrust-augmenting nozzle, 3-support bar, 4-are container; The 5-heated nozzle.
Embodiment
For understanding the utility model better, below in conjunction with drawings and Examples the technical solution of the utility model is further described, referring to Fig. 1:
Be used for the heat treated even heating supplementary unit of integral container by what the utility model was implemented, include umbrella hood 1, thrust-augmenting nozzle 2, support bar 3, umbrella hood 1 be arranged on heated nozzle 5 directly over, umbrella hood 1 is horn-like, big mouthful of loudspeaker downwards, hot gas flow is blocked avoids directly to upper punch.Umbrella hood 1 top offers the pore that runs through a umbrella hood wall thickness, thrust-augmenting nozzle 2 is the open tube of bending, thrust-augmenting nozzle 2 one ends link to each other with the pore of umbrella hood 1, and the other end leads to the cold zone in the container, and thrust-augmenting nozzle 2 and umbrella hood 1 are fixedly connected in the container 4 by support bar 3.In order to make heating more even, the pore thread connection of thrust-augmenting nozzle 2 and umbrella hood 1 can allow thrust-augmenting nozzle 2 rotate around pore as required, thereby guide the flame high temperature gas flow into designated area.
Use of the present utility model is: the gas-oil mixture at heated nozzle 5 places of pore setting is lighted, after flame and flue gas run into umbrella hood 1, part high temperature gas flow is kept off returning to flow downward to container 4 lower heating, part high temperature gas flow flows to other cold zone in container 4 left vertical end socket parts or the container 4 by the thrust-augmenting nozzle 2 that communicates on the umbrella hood, by changing the original trend of thermal-flame, reach the purpose of container 4 each position even heating like this.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
Claims (2)
1. one kind is used for the heat treated even heating supplementary unit of integral container, and it is characterized in that: it includes umbrella hood, thrust-augmenting nozzle, support bar, and it is horn-like that umbrella hood is, and big mouthful of loudspeaker downwards, and the umbrella hood top offers the pore that runs through a umbrella hood wall thickness; Thrust-augmenting nozzle is the open tube of bending, and thrust-augmenting nozzle one end links to each other with the pore of umbrella hood, and the other end leads to the cold zone in the container; Thrust-augmenting nozzle and umbrella hood are fixedly connected in the container by support bar.
