Description

Technical Field

[0001] This utility model belongs to the field of combustion engine technology, and in particular relates to a methanol cracking combustion engine for aluminum melting furnace. Background Technology

[0002] Methanol cracking combustion technology has attracted widespread attention due to its high combustion efficiency and low pollutant emissions. Currently, most methanol cracking burners on the market adopt a highly integrated integrated structure, which compactly arranges the cracking coil, burner, air supply system (volute and impeller), ignition electrode, control unit, and fuel valve assembly into one or two interconnected housings. Although this structure appears compact in its initial manufacturing, it has revealed many insurmountable defects during actual use and maintenance. 1. Extremely difficult to inspect and maintain: As a core reaction component, the pyrolysis coil is exposed to high temperatures for a long time and is prone to damage due to carbon buildup, catalyst failure, or thermal stress. At the same time, nozzles, ignition electrodes, etc. are also high-risk points for failure. When these components need to be inspected or replaced, due to the crowded internal space and the components blocking each other, maintenance personnel often need to carry out large-scale disassembly work. For example, they must first disassemble the external pipes and cables, and then move the entire air supply unit or control box before they can reach the core combustion reaction zone. This process is time-consuming, requires high technical skills from the operators, and is very easy to damage other adjacent components during disassembly and assembly, resulting in high maintenance costs and long equipment downtime.

[0003] 2. Space occupied by electrical layout: The PLC, relays, frequency converters and other electrical control units that are sensitive to heat and moisture need to be isolated from the high-temperature pyrolysis and combustion parts. Therefore, most of them use independent electrical cabinets, which will occupy too much space. At the same time, the distance between electrical components and control points becomes longer, and the corresponding wiring is too long and complicated, which is also not conducive to maintenance and repair.

[0004] 3. Inconvenient installation and layout: The bottom structure of many burners is irregular, and the bottom surface of the volute is not flush with the bottom surface of the main body. This results in poor stability when the equipment is installed on a boiler or other base, requiring additional supports or complicated leveling procedures, making installation inconvenient. In addition, the connection points of the valve group and the cracking coil are usually hidden deep inside the equipment. Once a leak occurs at the interface, it is extremely difficult to troubleshoot and tighten.

[0005] Therefore, there is an urgent need in this field for a new type of methanol cracking combustor structure that can achieve modular separation of functions, convenient maintenance and operation, and significantly improved safety level while ensuring structural compactness. Summary of the Invention

[0006] The purpose of this utility model is to provide a methanol cracking burner for aluminum melting furnace. By setting the connection point of the cracking coil mechanism and the feed valve group in the air supply chamber formed in the front box, and equipping it with a detachable top inspection cover, the connection point can be directly and clearly observed from above, and can be quickly tightened or replaced, thus completely solving the problem of difficult maintenance of pipeline connection points in traditional structures.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a methanol cracking burner for an aluminum melting furnace, including a combustion host; The combustion host includes a housing, a pyrolysis cylinder, an air supply system, a feed valve group, and a pyrolysis coil mechanism; The housing includes a volute housing, and a front housing is integrally provided on the front side of the volute housing. An arc-shaped partition is integrally provided in the upper part of the front housing, dividing the front housing into an air supply chamber and an electrical compartment that are not connected to each other. The air supply chamber is integrally connected to the exhaust end of the volute housing. The air supply system includes an air damper, a motor, and an impeller connected to the output end of the motor. The air damper and the motor are respectively installed on both sides of the volute casing, and the impeller is located inside the volute casing. The feeding valve assembly is installed on one side of the front box and located outside the air supply chamber. One end of the pyrolysis cylinder is fixed to the front box and connected to the air supply chamber through a detachable structure. The pyrolysis coil mechanism is installed inside the pyrolysis cylinder. The detachable structure includes two outer support lugs on both sides of the front housing and inner support lugs on both sides of the end of the pyrolysis cylinder. The gap between the inner support lugs is between the two outer support lugs on the same side of the front housing, and a fastening screw is provided between the inner support lugs and the two outer support lugs. The other side of the front box is provided with an electrical maintenance door opposite to the electrical compartment. The connection point between the feed valve group and the pyrolysis coil mechanism is located inside the air supply chamber.

[0008] Furthermore, it also includes a slide, which is a frame with a right-angled triangular structure with a sloping top. A slide rail is fixed to the top of the slide along the length direction. The mounting base of the combustion host slides along the slide rail via a slide block. A hydraulic cylinder is provided between the slide block and the tail end of the slide, which is parallel to the slide rail.

[0009] Furthermore, both sides of the slide rail are integrally provided with sliding edges, both sides of the slide block are provided with grooved wheels that roll along the sliding edges, and the front end of the slide block is fixed with a bracket that is connected to the end of the hydraulic cylinder telescopic rod.

[0010] Furthermore, the damper is provided with a through-type spindle, the spindle is provided with a disc located inside the damper, and an angle sensor connected to the spindle is fixed on the periphery of the damper.

[0011] Furthermore, the outer support lug located below the front housing is provided with a threaded opening, the bottom end of the fastening screw is threaded into the threaded opening, and the top end of the fastening screw is provided with a knurled screw head.

[0012] Furthermore, an inclined end tube is integrally fixed to the top of the pyrolysis cylinder, and a flange is provided at the outer end of the inclined end tube.

[0015] 2. This utility model achieves the connection between the pyrolysis cylinder and the housing through a detachable structure.

[0016] 3. This utility model provides a dedicated space for the electrical control unit through the independent and enclosed electrical compartment design of the front box. When the control system or cables malfunction, maintenance personnel only need to open the electrical inspection door on the side to carry out safe and focused work in an independent space isolated from high temperature and vibration environment, without affecting the combustion system and air supply system at all.

[0017] 4. By setting an integrated mounting base on the bottom surface of the volute housing and the front housing, this utility model can form a wide and flat mounting reference surface, which allows the entire burner to be placed stably and conveniently on various mounting foundations, greatly improving installation efficiency and stability, without the need for additional complex leveling or bracket manufacturing.
