Description

Technical Field

[0001] This utility model belongs to the field of burner technology, specifically relating to a semi-coke burner. Background Technology

[0002] A burner is a device that mixes fuel with an oxidant (usually air) and ignites it to produce a controlled flame or high-temperature gas. Its core function is to convert chemical energy into heat and light energy through a combustion reaction, and it is widely used in industrial heating, power generation, domestic heating, cooking, and engine propulsion. Burners can be classified into various types based on fuel type (e.g., gas, liquid, or solid) and combustion method (e.g., premixing, diffusion, or catalytic combustion). Their design must balance efficiency, safety, and environmental friendliness, and typically includes a fuel supply system, mixing device, ignition mechanism, and flame stabilization structure. Modern burners often integrate intelligent control systems to optimize combustion efficiency and reduce pollutant emissions.

[0003] Traditional burners cannot effectively burn semi-coke powder, resulting in low semi-coke utilization, resource waste, and limiting the efficient use of semi-coke. Utility Model Content

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example

[0024] Reference Figure 1-4 This embodiment of the present invention provides a semi-coke burner, including a burner body 110, an air inlet 120, a coal ignition zone 130, a preheating zone 140 and a combustion zone 150 sequentially disposed inside the burner body 110, a fan mechanism 160 disposed inside the air inlet 120, and a filter mechanism 170 fixedly installed inside the air inlet 120 for filtering air.

[0025] Air is introduced through the air inlet 120 and delivered to the preheating zone 140 and the combustion zone 150. The preheating zone 140 is responsible for fully mixing the semi-coke powder with the air, and then igniting the mixture under the action of the igniter 190, so that it enters the combustion zone 150 for stable combustion. This solves the problem that traditional burners cannot effectively burn semi-coke powder and improves the utilization rate of semi-coke. This device fills the technical gap in the inability of burners to burn semi-coke.

[0026] Specifically, the pulverized coal inlet ignition zone 130 is equipped with a pulverized coal inlet pipe 180 for the entry of semi-coke powder, and the pulverized coal inlet ignition zone 130 is equipped with an igniter 190 for igniting the semi-coke powder mixture.

[0027] The coal powder inlet pipe 180 is used to transport the semi-coke powder to the interior of the preheating zone 140, so that the semi-coke powder mixes with air, and the semi-coke powder mixture is ignited by the igniter 190.

[0028] Furthermore, the fan mechanism 160 includes a rotating shaft 161 rotatably mounted inside the air inlet 120, a plurality of fan blades 162 fixedly mounted on the surface of the rotating shaft 161 for air transport, a passive bevel gear 163 fixedly mounted on the end of the rotating shaft 161, and a motor 164 fixedly mounted on the surface of the burner body 110 for driving the rotating shaft 161 to rotate.

[0029] The motor 164 drives the active bevel gear 165 to rotate. Since the active bevel gear 165 and the passive bevel gear 163 mesh, the active bevel gear 165 drives the passive bevel gear 163 to rotate. The passive bevel gear 163 drives the rotating shaft 161 to rotate, and the rotating shaft 161 drives the fan blade 162 to rotate, drawing air in through the opening of the air inlet 120 to provide the oxygen required for the combustion of semi-coke.

[0030] Preferably, the output end of the motor 164 is fixedly mounted with an active bevel gear 165 that works in conjunction with the passive bevel gear 163, and the passive bevel gear 163 and the active bevel gear 165 mesh with each other.

[0031] Furthermore, a positioning bearing 166 for mounting the rotating shaft 161 is fixedly installed inside the air inlet 120 via a connecting rod, and the positioning bearing 166 is sleeved on the surface of the rotating shaft 161.

[0032] The positioning bearing 166 is used to install and fix the rotating shaft 161, thereby improving the stability of the rotating shaft 161 during rotation.

[0033] Specifically, the filtration mechanism 170 includes a filter 171 for filtering air, and a mounting sleeve 172 fitted onto the surface of the filter 171 and threaded into the air inlet 120.

[0034] The filter 171 and the mounting cylinder 172 work together to filter the air passing through the air inlet 120, preventing impurities in the air from affecting the combustion effect of the semi-coke.

[0035] Furthermore, two blocks for limiting the installation of the filter 171 are fixedly installed inside the air inlet 120, and an operating handle for easy rotation is fixedly installed on the surface of the mounting cylinder 172.

[0036] The stop block is used to block and limit the filter 171 and the mounting cylinder 172, preventing the mounting cylinder 172 from being installed too deep inside the air inlet 120, which would make disassembly inconvenient. The handle makes it easy to rotate the mounting cylinder 172, thereby facilitating the replacement of the filter 171 and ensuring its filtration performance.

[0037] In use, air is introduced through the air inlet 120 and delivered to the preheating zone 140 and the combustion zone 150. The preheating zone 140 is responsible for fully mixing the carbon powder with the air, and then igniting the mixture under the action of the igniter 190, so that it enters the combustion zone 150 for stable combustion.

[0038] Motor 164 drives active bevel gear 165 to rotate. Since active bevel gear 165 and passive bevel gear 163 mesh, active bevel gear 165 will drive passive bevel gear 163 to rotate. Passive bevel gear 163 drives shaft 161 to rotate. Shaft 161 then drives fan blade 162 to rotate, drawing air in through the opening of air inlet 120 to provide the oxygen needed for semi-coke combustion.
