Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments is as follows:

as shown in fig. 1, the remote ignition device disclosed by the invention comprises an oil tank 1, a gear oil pump 3, an ignition gun 9, a control box 6, a torch 10 and a 220V external power supply 13 for supplying power to the control box 6, wherein the oil tank 1 is connected with the gear oil pump 3 through an oil pipeline 2; the gear oil pump 3 is connected with the ignition gun 9 through a high-temperature and high-pressure resistant hose 8; the ignition gun 9 is fixedly arranged on an ignition port of the torch 10; the control box 6 is connected with the gear oil pump 3 through a control power supply circuit 14, the control box 6 is connected with the ignition gun 9 through a pulse high-voltage wire 7, and the control box 6 outputs high-voltage pulses to the ignition gun 9 through the pulse high-voltage wire 7, so that the gear oil pump 3 and the ignition gun 9 can be remotely controlled to work through the control box 6, and remote ignition operation is realized.

The remote ignition device also comprises a flame detector 11 electrically connected with the control box 6, wherein the flame detector 11 is used for detecting whether the torch 10 is burnt, so that whether the flame of the torch 10 is burnt and the burning condition of the flame can be determined through the flame detector 11.

Specifically, the flame detector 11 is connected to the control box 6 through a control line 12, and when the remote ignition control device works, the flame detector 11 transmits the detected flame condition to the control box 6 through the control line 12, and then the control box 6 controls the gear oil pump 3 and the ignition gun 9 to work according to the received detection result, so that the remote ignition control of the torch 10 is realized.

The remote ignition device further comprises a pressure adjusting assembly, the pressure adjusting assembly comprises a stop valve 4, an overflow valve 15, a pressure gauge 5 and a tee joint, the gear oil pump 3 is connected with a first connecting end of the tee joint, two ends of the stop valve 4 are respectively connected with a second connecting end of the tee joint and the overflow valve 15, and the other end of the overflow valve 15 is connected with the oil tank 1 through an oil return pipe 16; and two ends of the pressure gauge 5 are respectively connected with the third connecting end of the tee joint and the ignition gun 9.

When the overflow valve 15 and the pipeline between the overflow valve 15 and the oil tank 1 are in failure, the overflow valve 15 and the pipeline between the overflow valve 15 and the oil tank 1 can be replaced by opening the stop valve 4; moreover, the overflow valve 15 is preset with an overflow threshold, and when the pressure value detected by the pressure gauge 5 is greater than or equal to the overflow threshold, the overflow valve 15 is automatically opened to release pressure, so that the pressure in the pipeline is reduced; and when the pressure gauge 5 detects that the pressure value of the high-temperature and high-pressure resistant hose 8 is smaller than the overflow threshold value, the overflow valve 15 is automatically closed, so that the pressure in the high-temperature and high-pressure resistant hose 8 can be adjusted through the overflow valve, and the high-temperature and high-pressure resistant hose 8 is prevented from being broken due to overlarge pressure.

When the gear oil pump works specifically, a 220V external power supply 13 is connected with an external power supply device, a start key on the control box 6 is clicked, the gear oil pump 3 starts to work, and an indicator light of the gear oil pump 3 is turned on; the stop valve 4 is in an open state when the ignition device works or stops working; the gear oil pump 3 drives fuel oil in the gear oil pump 3 to enter the ignition gun 9 and vaporize after passing through an oil nozzle of the ignition gun 9; the control box 6 outputs high-voltage pulse to the ignition gun 9 through the pulse high-voltage wire 7, and the vaporized fuel at the moment is ignited and combusted after contacting the high-voltage pulse; then, after the flame detector 11 detects that the flame is burnt for more than 3 seconds, the control box 6 controls the pulse high-voltage wire 7 to stop outputting high-voltage pulses to the ignition gun 9, and when the flame detector 11 detects that the torch 10 starts burning, the control box 6 controls the gear oil pump 3 to stop working; when the flame detector 11 detects that the torch 10 does not start to burn, the control box 6 controls the gear oil pump 3 to work, and simultaneously controls the pulse high-voltage wire 7 to output high-voltage pulses to the ignition gun 9 until the flame detector 11 detects that the torch 10 starts to burn.
