For solving the problems of the technologies described above, the utility model provides a kind of blast furnace top firelock, comprise the ignition electrode being arranged in rifle head, be arranged on the gas passage that is communicated to described rifle head in gun barrel, be arranged on the pulse igniter being connected with described ignition electrode wire in described rifle body front handlebar, be arranged on and on rifle body front handlebar, be connected the igniting trigger for controlling described pulse igniter switch with described pulse igniter, the combustion-supporting gas pipeline, air duct and the inflammable gas pipeline that are connected with described rifle body, and be arranged on the flame control device at described rifle body rear portion.
Further, described flame control device comprises connecting rod, flame control valve, Compress Spring and Valve plug, described Valve plug is fixed on described connecting rod front end for stopping up described gas passage, rear end, the other end that one end of described Compress Spring is fixed on described connecting rod is fixed on the rear end of rifle body, the fixing described flame control valve in lower end of described connecting rod, described flame control valve is arranged on the rear handle of described rifle body, can be after described rifle body moves forward and backward in the groove of handle.
A kind of blast furnace top firelock that the utility model provides, simple to operate, easy to adjust.When use, open gas pipeline, can open pulse igniter by the igniting trigger on lower gun body front handlebar, by the ignition electrode being connected with pulse igniter, the fuel gas that arrives rifle head is lighted, then directly there is the connecting rod of Compress Spring by flame control valve control connection, adjusting is connected to the space between Valve plug and the gas passage entrance of connecting rod front end, thereby regulates the length that enters the gas flow of gas passage and control flame.Coal gas on inner furnace roof charge level can be lighted, horizontal and vertical movement that simultaneously can manual control rifle body carrys out the ignition angle of point of adjustment firelock, improves the success rate of igniting.
Brief description of the drawings
The blast furnace top firelock structural representation that Fig. 1 provides for the utility model embodiment.
The blast furnace top firelock that Fig. 2 provides for the utility model embodiment is at manhole place igniting schematic diagram.
Detailed description of the invention
Referring to Fig. 1, a kind of blast furnace top firelock that the utility model embodiment provides, comprise the ignition electrode 1 being arranged in rifle head, be arranged on the gas passage 2 that is communicated to rifle head in gun barrel, be arranged on the pulse igniter 4 being connected by wire with ignition electrode 1 in rifle body front handlebar, be embedded in and on rifle body front handlebar, be connected the igniting trigger 3 for control impuls igniter 4 switches with pulse igniter 4, the combustion-supporting gas pipeline 8, air duct 10 and the inflammable gas pipeline 11 that are connected by quick coupling with rifle body, and be arranged on the flame control device at rifle body rear portion.Because igniting trigger 3 is connected with pulse igniter 4, pulse igniter 4 is connected with ignition electrode 1, just can open pulse igniter 4 as long as pull igniting trigger 3, and pulse igniter 4 can be lighted gas by ignition electrode 1, convenient to use.
Wherein, flame control device comprises connecting rod 5, flame control valve 6, Compress Spring 7 and Valve plug 9, Valve plug 9 is fixed on connecting rod 5 front ends for stopping up gas passage 2, rear end, the other end that one end of Compress Spring 7 is fixed on connecting rod 5 is fixed on the rear end of rifle body, the fixing flame control valve 6 in lower end of connecting rod 5, flame control valve 6 is embedded on the rear handle of rifle body, can be after rifle body moves forward and backward in the groove of handle.While work, Valve plug 9 will be communicated to gas passage 2 plugs for seal of rifle head under the elastic force effect of Compress Spring 7.When work, pin flame control valve 6, make it pass through the motion backward together with Valve plug 9 of Compress Spring 7 drivening rods 5, Valve plug 9 leave gas passage 2 entrance and and between gas passage 2, produce space, combustion-supporting gas enters gas passage 2 in the mobile space staying backward by Valve plug 9, arrives rifle head and participates in burning.When flame control valve 6, displacement is larger backward, displacement is just larger backward to drive Valve plug 9, between Valve plug 9 and gas passage 2, produce space just larger, from then on to enter the combustion-supporting gas of gas passage 2 just more in space, and the flame that gas combustion produces is just longer.And because the horizontal and vertical movement of this blast furnace top firelock handled easily personnel control rifle body carrys out the ignition angle of point of adjustment firelock, the ignition operation while being easy to realize coal gas margin development, has improved the success rate of igniting.
The course of work of a kind of blast furnace top firelock that the utility model embodiment provides is as follows: before igniting, after checking out that with gas leak detector near CO concentration blast furnace is in range of safety operation.The joint of compression combustion-supporting gas pipeline 8, air duct 10 and inflammable gas pipeline 11 is connected with the interface on the body of a gun respectively, and joint and interface coordinate in screw and nut mode, this fit system good airproof performance, coordinate firm, connection and convenient disassembly.Referring to Fig. 2, after pipeline and rifle body connect, the rifle head of burning torch is inserted in blast furnace from the manhole of blast furnace, open the valve on inflammable gas pipeline 11, press down-firing trigger 3, open pulse igniter 4, ignition electrode 1 connected with pulse igniter 4 on rifle head can be lighted the fuel gas that is connected coke-oven coal gas bag at rifle head.
After fuel gas is lighted, open the valve on air duct 10 and compression combustion-supporting gas pipeline 8, for gas fuel burning provides sufficient oxygen.Then pin flame control valve 6, make it pass through the motion backward together with Valve plug 9 of Compress Spring 7 drivening rods 5, space after combustion-supporting gas moves backward by Valve plug 9 and between gas passage 2 entrances enters gun barrel, flame control valve 6 backward displacement is larger, displacement is just larger backward to drive Valve plug 9, space between Valve plug 9 and gas passage 2 entrances is just larger, the combustion-supporting gas that enters gas passage 2 is more, the flame that burning produces is just longer, moving left and right and moving up and down by operating personnel control point firelock, until the gas on the charge level of furnace roof inner space is lighted.After igniting, unclamp flame control valve 6, connecting rod 5, under the elastic force effect of Compress Spring 7, drives Valve plug 9 to travel forward together, and Valve plug 9 moves forward blocks the gas passage 2 that enters gun barrel, fray-out of flame.Then the valve on closes compression combustion-supporting gas pipeline 8, inflammable gas pipeline 11 and air duct 10.Exit point firelock from blast furnace manhole, unloads being connected of each gas pipeline joint and rifle body interface, can realize separating of rifle body and gas pipeline.
It should be noted last that, above detailed description of the invention is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
