Also be provided with manually-operated gate between described gas blow pipe and air header.Be provided with pressure sensor in the described combustion furnace.Described combustion furnace is provided with the gripper shoe of symmetrical distribution corresponding to the end of contiguous gas blow pipe, and described gas blow pipe and gripper shoe fix.
Described gripper shoe is provided with reinforcement corresponding to the other end that links to each other with combustion furnace, and the two ends of described reinforcement fix with corresponding gripper shoe respectively.Described gas blow pipe is provided with the gas blow pipe valve corresponding to the other end that links to each other with air header.Described automatic valve is the electrical servo valve.Described pressure sensor links to each other with the input of controller, and automatic valve links to each other with the output of controller.
Advantage of the present invention: gas blow pipe is connected with air header, and the corresponding surface of gas blow pipe and chimney is provided with gas hole; Pressure sensor detects the gas furnace pressure inside, when the gas furnace pressure inside is lower than external pressure, automatic valve is opened, gas blow pipe is connected with air header, the gas of air header blows out by gas hole, thereby the end at gas furnace forms gas curtain, avoids external oxygen to enter in the burner hearth of gas furnace, avoids the workpiece in the burner hearth oxidized; When the gas furnace pressure inside was higher than external pressure, automatic valve was closed, and the gas in the gas furnace discharges by chimney, made the interior constant compression force that keeps of burner hearth of gas furnace.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the C-C of Fig. 1 is to view.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 2: the present invention includes air header 1, manually-operated gate 2, automatic valve 3, gas furnace 4, chimney 5, gas blow pipe 6, pressure sensor 7, support 8, reinforcement 9, gas hole 10, gas blow pipe valve 11 and gripper shoe 12.
As depicted in figs. 1 and 2: described chimney 5 is positioned at an end of gas furnace 4, and chimney 5 is connected with the burner hearth of gas furnace 4.Utilize support 8 that air header 1 is installed on the outer wall of gas furnace 4, one end of described air header 1 is provided with gas blow pipe 6, one end of described gas blow pipe 6 is connected with air header 1, and the other end is positioned at the below of chimney 5, and gas blow pipe 6 is pressed the radial direction distribution of gas furnace 4.1 of gas blow pipe 6 and air header are provided with manually-operated gate 2 and automatic valve 3, being communicated with and closing of described manually-operated gate 2, automatic valve 3 control gas blow pipes 6 and 1 of air header.Manually-operated gate 2 can be in opening always, only needs the switching of control automatic valve 3 just can realize controlling the connected state of 1 of gas blow pipe 6 and air header; Automatic valve 3 is the electrical servo valve.Gas blow pipe 6 is provided with gas blow pipe valve 11 corresponding to the other end that links to each other with air header 1, and described gas blow pipe valve 11 is a manually-operated gate; Described gas blow pipe valve 11 is a normally close valve.
Be provided with pressure sensor 7 in the gas furnace 4, the gas pressure that described pressure sensor 7 detects in gas furnace 4 burner hearths, and described force value is transferred in the controller, controller is according to combustion furnace 4 burner hearth external and internal pressure values, the switching of control automatic valve 3, thereby the connected state of 1 of control gas blow pipe 6 and air header.Described controller can be single-chip microcomputer or other microprocessor.
Gas furnace 4 is provided with the gripper shoe 12 of symmetrical distribution corresponding to the end that chimney 5 is set, and described gripper shoe 12 fixes with gas furnace 4.Gas blow pipe 6 is installed in the end of gas furnace 4 by gripper shoe 12, and gas blow pipe 6 is fixedly connected with gripper shoe 12.Gripper shoe 12 is provided with reinforcement 9 corresponding to the other end that links to each other with gas furnace 4, and the two ends of described reinforcement 9 fix with corresponding gripper shoe 12 respectively, guarantees the bonding strength of 6 of gripper shoe 12 and gas blow pipes.
