Detailed Description
The ring heating apparatus according to the present invention will be described in detail below. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.
Example 1
Referring to fig. 1, the annular heating device of the present invention includes an annular heating pipe 1, the annular heating pipe 1 encloses a heating zone, the annular heating pipe 1 has a plurality of nozzles 2 towards the heating zone, the annular heating pipe 1 is connected to a gas-fired heat energy device 41, and the annular heating pipe 1 is provided with a flow adjusting portion 5 for controlling the flow of the nozzles 2.
As a further improvement of the present embodiment, the annular heating pipe 1 is connected to the gas-fired thermal energy device 41 through a flange 3.
As a further improvement of this embodiment, the gas-type thermal energy device 41 includes a valve 411, a handle 412 and a hose 413, wherein one end of the valve 411 is connected to the flange 3, the other end of the valve is connected to one end of the handle 412, and the other end of the handle 412 is connected to the hose 413.
As a further improvement of this embodiment, the flow rate adjusting part 5 is a ball valve, and the flow rate adjustment can be realized by rotating a ball valve switch.
The utility model discloses the working process of annular heating device embodiment, including following step:
step S1: a hose 413 of the gas heat energy device is communicated with a natural gas bottle, and a switch of the natural gas bottle, a valve 411 and a nozzle 2 are all set to be in a closed state;
step S2: sequentially opening a natural gas bottle switch and a valve 411 in sequence, then opening a nozzle 2 farthest from a natural gas inlet end in the annular heating pipe 1, igniting the natural gas flowing for 30 seconds left and right to exhaust air in a pipeline, then opening the other nozzles 2 one by one and igniting the nozzles, and rotating the ball valve to ensure that the flow of the natural gas at the nozzle 2 is proper and uniform;
step S3: placing a heat-shrinkable sleeve to be shrunk and a wire cable protected by the heat-shrinkable sleeve in the middle of the annular heating pipe 1, and enabling the annular heating pipe 1 to axially move along the heat-shrinkable sleeve;
