[0002] A hot blast furnace is a device that burns materials to raise the furnace temperature, thereby providing high-temperature hot air. It is usually divided into two types: manual ignition and automatic ignition by an igniter.

[0003] In the automatic ignition mode of the igniter, the igniter is usually installed on one side of the furnace wall to ignite the particles fed in advance into the furnace. However, when the particles in the furnace are completely burned, the surface temperature of the furnace wall will be very high. Therefore, the igniter is easily damaged under long-term baking and is not durable.

[0004] In view of this, it is necessary to propose an ignition structure to solve or at least alleviate the above defects. Summary of the invention

[0014] Preferably, the diameter of the discharge section is larger than the diameter of the feed section.

[0015] Preferably, the distance between the second end of the auger and the discharge section is 15 cm to 20 cm.

[0016] Preferably, the ignition mechanism adopts an ignition rod, and the drive assembly adopts a drive motor.

[0017] Preferably, the inclination angle of the discharging section is 25° to 30°.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] An ignition structure provided by the present invention includes an assembled feeding mechanism, a hopper, an ignition mechanism and a furnace. The assembled feeding mechanism includes an assembly pipe, an auger and a driving assembly.

This can prevent the ignition mechanism from being damaged by the high temperature of the furnace for a long time. Since the ignition zone is only initially ignited and not continuously burned, and as the ignited material is pushed forward at any time, its temperature will not be too high.

[0030] Please see attached Figure 1-2In one embodiment of the present invention, an ignition structure is provided, which includes a feeding mechanism 10, a hopper 20, an ignition mechanism 30 and a furnace 40. First of all, it should be noted that, unlike the prior art, the igniter is usually installed on one side of the furnace 40 wall to ignite the particles fed in advance in the furnace 40. However, when the particles in the furnace 40 are completely burned, the surface temperature of the furnace 40 wall will be very high, so the igniter is easily damaged under long-term roasting and is not durable. The present application solves the above-mentioned defects in the prior art by setting an ignition structure, which is as follows:

[0031] The assembly feeding mechanism 10 includes an assembly pipe 110, an auger 120 and a drive assembly 130, wherein the assembly pipe 110 includes a discharge section 111, a feeding section 112 and a drive section 113 which are sequentially connected and arranged; wherein the discharge section 111 is connected to the furnace 40 and is connected and arranged in communication with the furnace 40, the drive assembly 130 is connected to the drive section 113, the first end of the auger 120 is connected to the drive section 113 of the drive assembly 130 so as to be rotatably arranged in the feeding section 112, and a feed port 114 is provided at the top of the feeding section 112, the bottom end of the hopper 20 is connected and arranged in communication with the feed port 114, an ignition zone 115 is provided at one end of the feeding section 112 close to the discharge section 111, and the ignition mechanism 30 is connected to the feeding section 112 and its ignition end extends into the ignition zone 115.

[0032] Specifically, the ignition structure in the present application includes an assembly feeding mechanism 10, a hopper 20, an ignition mechanism 30 and a furnace 40. The assembly feeding mechanism 10 is used for temporarily storing material particles and feeding them into the furnace 40, and is assembled on the side wall of the furnace 40. The hopper 20 is used to store material particles that need to be burned and transport material particles to the assembly feeding mechanism 10, and the ignition mechanism 30 serves as an ignition source to ignite the material particles. The ignited material particles enter the furnace 40 to provide high-temperature hot air.

[0033] The assembly feeding mechanism 10 includes an assembly pipe 110, an auger 120 and a drive assembly 130. The assembly pipe 110 is used for installing the auger 120, the ignition mechanism 30 and the drive assembly 130. The assembly pipe 110 has an assembly chamber inside, which is convenient for installation. The assembly pipe 110 includes a discharge section 111, a feed section 112 and a drive section 113 which are connected in sequence. The discharge section 111 serves as a channel for the material particles in the assembly pipe 110 to enter the furnace 40. The feed section 112 is a channel for the material particles in the assembly pipe 110 to enter the furnace 40. The auger 120 is arranged in the feeding section 112, and a feeding port 114 is provided on the top of the feeding section 112 to facilitate communication with the hopper 20. The driving section 113 is used for installing the driving assembly 130. By connecting the driving end of the driving assembly 130 with the auger 120, the auger 120 is driven to rotate by the driving assembly 130, so as to achieve the purpose of conveying the material particles to the furnace 40. Preferably, the driving section 113 is used for installing the driving assembly 130. The driving assembly 130 can be a driving motor, which has a compact structure and is easy to install. Furthermore, an ignition zone 115 is provided at one end of the feeding section 112 close to the discharging section 111, so that when the auger 120 transports the material particles to the ignition zone 115, the ignition mechanism 30 performs preliminary ignition. When the subsequent material particles are transported to this ignition zone, the ignited material particles are pushed forward due to the thrust of the material particles, so that the preliminarily ignited material particles fall to the furnace 4 through the discharging section 111. 0, high-temperature hot air is delivered after the accumulation of combustion time is sufficient, thus avoiding the traditional method of installing the ignition mechanism 30 on the side wall of the furnace 40, and at the same time, the material particles are continuously pushed forward and replaced, and the initial combustion in the ignition zone 115 will not have a high combustion temperature, so as to extend the service life of the ignition mechanism 30; preferably, the ignition mechanism 30 can use an ignition rod, which does not need to rely on an external ignition source or ignition material, and does not lose its ignition function due to wind blowing out. It has high reliability and a long service life.

[0034] As a preferred embodiment of the present invention, the second end of the auger 120 is spaced apart from the discharge section 111 to reserve the ignition zone 115 .

[0035] It should be noted that the length of the auger 120 is shortened so that its second end is spaced apart from the discharge section 111 to form an ignition zone 115. The ignition zone 115 can provide a place for the pushed material particles to temporarily stay and be heated and ignited by the ignition mechanism 30 at the top. This can also prevent the ignition mechanism 30 from burning the auger 120 to protect the auger 120. Preferably, the spacing distance can be set to 15 cm to 20 cm, and technicians in this field can choose according to actual needs.

[0036] As a preferred embodiment of the present invention, the discharge section 111 is arranged to be inclined downward toward the furnace 40 .

[0037] It should be noted that, since the initially ignited material particles in the ignition zone 115 are only pushed by the subsequent conveying material particles, setting the discharge section 111 to be inclined downward toward the furnace 40 can make it easier for the initially ignited material particles to fall into the furnace 40 to avoid material pile-up and blockage; preferably, the inclination angle can be set to 25°~30°, and technicians in this field can set it according to specific circumstances.

[0038] As a preferred embodiment of the present invention, it also includes a furnace mesh 410, which is connected to the inner middle part of the furnace 40 and arranged below the discharge section 111, and a first air inlet 420 is also opened at the bottom of the furnace 40.

[0039] It is worth mentioning that the furnace net 410 is used to receive the preliminary ignition material particles fed into the furnace 40, so as to form a space with the bottom of the furnace 40 to ensure a combustion space with oxygen circulation to ensure the subsequent combustion of the ignited material particles, and a first air inlet 420 is also opened at the bottom of the furnace 40 to facilitate ventilation and thus increase the combustion effect.

[0040] As a preferred embodiment of the present invention, a second air inlet 116 is provided at the bottom of the feeding section 112 near the ignition zone 115 .

[0041] It is worth noting that the second air inlet 116 is used to ensure that the assembly tube 110 is also in a ventilated environment to ensure the continuity of ignition of the ignition mechanism 30. Therefore, an air inlet channel can be protruded at the bottom of the feeding section 112 near the ignition zone 115, and then the second air inlet 116 can be opened.

[0042] Furthermore, a flange plate is provided at one end of the feeding section 112 close to the driving section 113 , and the driving section 113 is detachably connected to the feeding section 112 by bolts penetrating the flange plate.

[0043] It should be noted that this allows for easy disassembly and installation at any time to replace and maintain the auger 120 and the drive assembly 130 .

[0044] Furthermore, the diameter of the discharge section 111 is greater than the diameter of the feed section 112 .

[0045] It should be understood that this is done to avoid material blockage in the discharge section 111, and because the material fuel is already in a ignited state, the pipe diameter is increased to increase the combustion space.

[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
