Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to antifreezing of railway lines, and more particularly to a cantera device for antifreezing of points.

[0002]

[Prior art]

 Conventionally, in a railway line antifreezing device, the liquid fuel such as kerosene is used in a cantera which has a core at the mouth of a fuel container similar to a kerosene lamp and used as a crater.

[0003]

[Problems to be solved by the device]

 The conventional railway track antifreezing cantera described in the above-mentioned conventional items must be ignited one by one for ignition, which is a time-consuming operation in a wide railway yard. And once ignited, the power could not be adjusted or extinguished, and had to be left alone until the fuel burned out.

In this invention, it is necessary to set the canteras under the rails one by one, but after that, automatic ignition can be performed by pressing the switch once, and it is not necessary to keep the ignition until ignition. Also, the purpose was to make adjustments freely by turning the cock and to easily extinguish a fire by using the cock.

[0007] Further, for example, by connecting a connecting fitting and connecting it to an oil storage tank through a connecting pipe, it is possible to centrally supply fuel to four points, six points, and a cantera required for one point.

[0006]

The anti-freezing cantera device for a railway line has an ignition heater which is housed separately in one direction and is close to the pilot wick combustion section.

The ignition heater may have a base end supported by a support tube, and the support tube may be inserted with an electric wire connected to the ignition heater.

A small combustion inner cylinder having an upper end opened inwardly of the combustion cylinder and a lower end formed with air holes as required has a lower end connected to the outer peripheral surface of the mandrel cylinder, and an ignition heater for the combustion inner cylinder. It is advisable to approach / oppose the inner space to the interval required for the combustion of the pilot wick combustion section.

The other end of the support pipe is fitted and supported by a receiving pipe provided on a support plate on the tank, and a conducting wire leading to the ignition heater is drawn out, and this is connected to an electric circuit for supplying electric power for a certain time by a switch. The wick is connected to the inside of the tank by providing a cock, and this cock is associated with a handle provided outside the tank, and the operation of the handle opens or closes the oil supply passage to the wick. It is good to switch.

The wick accommodating cylinder communicates with an oil feed pipe provided with a cock, and this cock is associated with a handle provided outside the tank, and the oil feed passage to the wick accommodating cylinder is opened or closed by operating the handle. It is good to switch to.

When a cam that opens and closes an electric contact is attached to the handle shaft and the handle is rotated to open the oil feed pipe, the fuel oil in the tank flows into the lead housing cylinder, and the main circuit of the electric circuit of the ignition heater is opened. It is good to turn on the switch and heat the ignition heater by the timer circuit or the ignition switch to burn the burning portion of the pilot lead and then burn the burning portion of the main lead.

It is preferable that one end of the oil feed pipe communicating with the wick housing cylinder is arranged outside the tank, the oil feed pipe is connected to this, and the central oil feed tank is connected to the central oil storage tank.

[0013]

[Action]

 Since the present invention is configured as described above, when the ignition heater 15 is turned on, heat is generated to ignite the pilot wick combustion section 13a, and the main wick 6 is burned by the combustion to generate a required flame from the combustion cylinder 8. It is what is generated.

When a small combustion inner cylinder 10 having an open upper end inside the combustion cylinder 8 and a required air hole 9 provided in the lower half is arranged, the combustion of the main core 6 is stabilized.

The lower half of the main core 6 is housed in the core housing cylinder 7, and the core housing cylinder 7 communicates with the central tank inside or outside the tank 2 via the cock 22, so that the cock 22 can be operated. Therefore, it is possible to extinguish the fire by cutting the fuel, or to adjust the flow rate to adjust the thermal power.

The handle 22 is turned to open the cock 22, the main switch 28 is closed by the cam 27 attached to the shaft, the electric circuit automatically ignites, or the ignition switch 29 is pushed once, and then automatically controlled by electronic control. It is also possible to ignite selectively. If a solenoid valve is used for the cock 22, it can also be activated and automatically stopped over time.
