Technical Field

[0001] The utility model relates to the technical field of roaster ignition guns, in particular to a novel combustion chamber which improves the success rate of ignition. Background Art

[0002] Roasters are primarily used in steel mills to bake newly built ladles, hot metal ladles, and scrap heating. The ignition gun is crucial to the proper and efficient operation of the roaster. Currently used roasters primarily consist of an ignition gun and an electrical control system. Roasters use industrial gas and oxygen as combustion aids, resulting in high-temperature flames reaching temperatures exceeding 1300°C.

[0003] However, the existing roaster has only one ventilated air cavity inside the ignition gun, and the gas is directly discharged from the ignition gun. In this way, the gas has the problem of unstable gas pressure, and the gas is directly ejected, and the flame power is low, which affects the use effect of the device and is not conducive to the use of the device. Utility Model Content

[0004] The purpose of the present utility model is to provide a new combustion chamber with improved ignition success rate, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present utility model provides the following technical solutions: a new combustion chamber for improving the ignition success rate, comprising an ignition gun barrel body one, a fire stopper, an ignition gun barrel body two, a guide, an input pipe and a compensation seam, one end of the ignition gun barrel body one is fixedly connected to the ignition gun barrel body two, a fire stopper is installed on the inner wall of the ignition gun barrel body two through a mounting component, an input pipe is connected to the inner wall of the end of the ignition gun barrel body two away from the ignition gun barrel body one, a compensation seam is opened on the wall of the end of the ignition gun barrel body two close to the input pipe, and a guide is integrally formed on the inner wall of the ignition gun barrel body one.

[0006] In a preferred embodiment: the fire stop is obliquely arranged in the second ignition gun barrel body, and the fire stop is provided in two groups, and the two groups are symmetrically distributed, the number of the fire stop in each group is 3, and they are distributed at equal distances, and the wall thickness of the fire stop is 2 mm.

[0007] In a preferred embodiment, each of the fire stoppers is provided with a first notch, a second notch and a third notch, wherein the second notch is circular and the third notch is rectangular.

[0008] In a preferred embodiment, the compensation seams are divided into two groups and are symmetrically distributed. Each group of compensation seams has three compensation seams and are equidistantly distributed.

[0009] In a preferred embodiment, the guide is a Laval port airflow guide, and one end of the ignition gun barrel body 1 away from the ignition gun barrel body 2 is fixedly connected to the ignition gun nozzle.

[0010] In a preferred embodiment: the mounting component includes a mounting plate fixedly connected to the inner wall of the second ignition gun barrel body, internal threads opened on the mounting plate and the inner walls of multiple fire stoppers, and a fastening bolt threadedly connected to the internal threads. A slot is also provided on the inner wall of the second ignition gun barrel body, and the slot matches the arc-shaped wall at one end of the fire stopper.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0012] The utility model can effectively turbulently mix the gas and then spray it out by arranging a first ignition gun tube body, a fire stopper, a second ignition gun tube body, a guide, an input pipe and a compensation seam, so as to improve the ignition success rate. Compared with the traditional method of directly spraying gas out of the ignition gun, the gas pressure of this device is more stable, and the flame power is also strong and powerful, which increases the use effect of the device and is conducive to the use of the device. The fire stopper is obliquely arranged and symmetrically distributed, and the design of multiple equidistant distributions in each group can better play the role of turbulence, so that the gas flow rate decreases. The different shapes of slots on the fire stopper can increase the turbulence of the airflow, so that the gas and the supporting gas can be better mixed, further improving the ignition effect. The pressure can be balanced by setting the compensation seam, and the stability of the combustion chamber can be improved. The Laval mouth airflow guide can guide the airflow, optimize the combustion process, and increase the strength of the flame. The setting of the mounting component makes the installation and disassembly of the fire stopper more convenient, and facilitates maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-4 The utility model provides a technical solution: a new combustion chamber for improving the ignition success rate, comprising an ignition gun barrel body 1, a fire stop 2, an ignition gun barrel body 2 3, a guide 4, an input pipe 5 and a compensation seam 6, one end of the ignition gun barrel body 1 is fixedly connected to the ignition gun barrel body 2 3, a fire stop 2 is installed on the inner wall of the ignition gun barrel body 2 3 through a mounting component, the input pipe 5 is connected to the inner wall of the end of the ignition gun barrel body 2 3 away from the ignition gun barrel body 1, a compensation seam 6 is opened on the wall of the end of the ignition gun barrel body 2 3 close to the input pipe 5, and a guide 4 is integrally formed on the inner wall of the ignition gun barrel body 1.

[0021] During use, the input pipe 5 inputs gas, the compensation seam 6 balances the pressure to ensure stable operation of the combustion chamber, and the fire stop 2 disturbs the gas to reduce the gas flow rate, thereby allowing the gas input from the input pipe 5 and the supporting gas entering from the compensation seam 6 to be more evenly mixed. The mixed gas then flows into the ignition gun barrel body 1, guides the airflow through the Laval mouth airflow guide, accelerates the gas flow rate, improves the ignition success rate, and makes the flame strong and powerful.

[0022] The fire stop 2 is obliquely arranged in the ignition gun barrel body 2 3. There are two groups of fire stop 2, and the two groups are symmetrically distributed. The number of fire stop 2 in each group is 3, and they are distributed at equal distances. The wall thickness of the fire stop 2 is 2 mm.

[0023] Each fire stop 2 is provided with a notch 1 7 , a notch 2 8 and a notch 3 9 , wherein the notch 2 8 is circular and the notch 3 9 is rectangular.

[0024] The compensating slits 6 are arranged in two groups, which are symmetrically distributed. Each group of compensating slits 6 has three compensating slits 6, which are equally spaced. The compensating slits 6 are arranged near the input pipe 5, which is an area where pressure changes more frequently. This can respond more directly to pressure changes and quickly balance the pressure, avoiding the problem of pressure fluctuations caused by the gas and supporting gas entering the ignition gun barrel body 3 at this location.

[0025] The guide 4 is a Laval port airflow guide, and one end of the ignition gun barrel 1 away from the ignition gun barrel 2 3 is fixedly connected to the ignition gun nozzle 10.

[0026] The mounting component includes a mounting plate 11 fixedly connected to the inner wall of the ignition gun barrel body 2 3, internal threads opened on the mounting plate 11 and the inner walls of multiple fire stoppers 2, and a fastening bolt 12 threadedly connected to the internal threads. A slot 13 is also provided on the inner wall of the ignition gun barrel body 2 3, and the slot 13 matches the arc-shaped wall at one end of the fire stopper 2.

[0027] Insert one end of the fire stop 2 into the slot 13 on the inner wall of the ignition gun barrel body 2 3, use the slot 13 to preliminarily position the fire stop 2, and then fix the fire stop 2 to the mounting plate 11 by tightening the bolts 12 to complete the installation of multiple fire stoppers 2.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
