Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace gas treatment, in particular to a blast furnace gas relief ignition device. Background Art

[0002] At present, with the increasingly strict industrial production safety standards and the general improvement of environmental protection awareness, more stringent requirements have been put forward for the treatment method of gas relief. As a combustible gas, when gas is directly discharged into the atmosphere without treatment, it not only seriously threatens the lives of surrounding personnel, is extremely likely to cause poisoning accidents and cause irreparable damage, but also seriously violates environmental protection regulations, directly exacerbates air pollution and has a long-term negative impact on the ecological environment.

[0003] Therefore, in order to ensure the safety of production operations and the sustainability of the environment, the generally adopted measure at present is that before the blast furnace gas is relieved through the outlet pipe, an ignition combustion procedure must be implemented. This step uses a specially designed ignition system to accurately ignite the gas with an ignition gun, so that it burns fully at high temperature and is discharged after being converted into harmless carbon dioxide and water vapor, thus avoiding the poisoning risk caused by direct gas discharge and effectively reducing environmental pollution.

[0004] However, it is worth noting that during the process of gas relief and combustion, due to the rapid expansion of the gas and the strong impact force generated by the combustion reaction, violent vibrations often occur. This vibration acts on the ignition gun and its installation structure, easily causing the ignition gun to shake or even collide, and then damaging or cracking the precise electronic components inside the ignition gun, especially key components such as transistors. As an important component for controlling the ignition timing and current in the ignition gun, once a transistor is damaged, it will directly affect the stability and reliability of the ignition system, manifested as problems such as ignition delay, ignition failure or insufficient ignition energy, and then affect the effect and safety of gas relief combustion. Summary of the Invention

[0005] The purpose of the utility model is to provide a blast furnace gas relief ignition device aiming at the above deficiencies of the prior art, so as to achieve the purpose of separating the ignition gun from the torch barrel after ignition is completed.

Jacks are arranged on the cylinder wall of the torch cylinder body. The ignition mechanism comprises an arc-shaped baffle, a guiding sleeve, a guiding piston, a guiding rod, an ignition gun, a connecting plate, a first telescopic rod and a second telescopic rod. A supporting frame is installed on the outer wall of the torch cylinder body. The arc-shaped baffle is attached to the outer wall of the torch cylinder body and is in sliding fit with the supporting frame. A guiding sleeve is installed on the arc-shaped baffle. A stepped guiding through hole arranged along the axis line is formed in the guiding sleeve. The stepped guiding through hole is coaxially arranged with the jack and is communicated with the jack. A guiding piston is slidably installed in the stepped guiding through hole. A tension spring is connected between the guiding piston and the top wall of the stepped guiding through hole. One end of the guiding rod is connected with the guiding piston, and the other end of the guiding rod passes through the stepped guiding through hole and is connected with one end of the connecting plate. An iron block is installed at the other end of the connecting plate. A first telescopic rod is installed on the bottom plate of the supporting frame. The inner rod of the first telescopic rod is connected with an electromagnetic chuck. After the electromagnetic chuck is electrified, it can adsorb the iron block. The outer end of the arc-shaped baffle is connected with the supporting frame through a second telescopic rod.

[0007] Further, the axis line of the jack on the torch cylinder body is arranged obliquely with respect to the axis line of the torch cylinder body. The outer end opening of the jack is higher than the inner end opening. The guiding sleeve is installed obliquely on the arc-shaped baffle, and the outer end of the guiding sleeve is higher than the inner end.

The upper end of the arc-shaped baffle is placed in the slide way of the upper slide plate, and the lower end is placed in the slide way of the lower slide plate. The arc-shaped baffle is in sliding fit with the slide ways of the upper slide plate and the lower slide plate.

[0009] Further, two symmetrically distributed guiding blocks are arranged on the inner wall of the small-diameter hole of the stepped guiding through hole. Two symmetrically distributed guiding grooves are arranged on the outer wall of the guiding rod. The guiding blocks are placed in the guiding grooves and are in sliding fit with each other.

The large-diameter hole is communicated with the jack. A guiding piston is slidably installed in the large-diameter hole. The other end of the guiding rod passes through the small-diameter hole and is connected with one end of the connecting plate.

[0011] Further, an ear plate is installed at the outer end of the arc-shaped baffle. A second telescopic rod is installed on the base of the supporting frame.

The ignition mechanism 3 includes an arc-shaped baffle 307, a guide sleeve 301, a guide piston 309, a guide rod 303, a ignition gun 302, a connecting plate 304, a first telescopic rod 306 and a second telescopic rod 308.

[0024] The support frame 2 is fixedly installed on the outer wall of the torch cylinder body 1.

[0025] The upper end of the arc-shaped baffle 307 is placed in the slide way of the upper slide plate 201, and the lower end is placed in the slide way of the lower slide plate 202. The arc-shaped baffle 307 is in sliding fit with the slide ways of the upper slide plate 201 and the lower slide plate 202. The arc-shaped baffle 307 is attached to the outer wall of the torch cylinder body 1. A guide sleeve 301 is installed on the arc-shaped baffle 307. The guide sleeve 301 is installed obliquely on the arc-shaped baffle 307, and the outer end of the guide sleeve 301 is higher than the inner end. A stepped guide through hole arranged along the axis is provided on the guide sleeve 301, and the axis of the stepped guide through hole is arranged coaxially with the axis of the insertion hole.

[0026] The inner end hole of the stepped guide through hole of the guide sleeve 301 is a large-diameter hole, and the outer end hole is a small-diameter hole. The large-diameter hole is communicated with the insertion hole. A guide piston 309 is installed in the large-diameter hole. The guide piston 309 is in sliding fit with the large-diameter hole. The guide piston 309 is connected with the top wall of the large-diameter hole through a tension spring 311. One end of the guide piston 309 is fixedly connected with one end of a guide rod 303. The other end of the guide rod 303 passes through the small-diameter hole and is fixedly connected with one end of a connecting plate 304.
