Description
Technical Field
[0001] This utility model relates to the field of boiler ash removal technology, and in particular to an ash removal device for boiler inspection. Background Technology
[0002] Boiler cleaning refers to the operation of cleaning the dust and impurities accumulated on the heating surfaces and flue during boiler operation. The purpose is to improve heat transfer efficiency, reduce energy consumption, prevent corrosion and wear of components, and ensure the safe and efficient operation of the boiler.
[0003] The boiler inspection cleaning device can quickly and effectively remove dust and slag inside the boiler before inspection, allowing inspectors to accurately observe the equipment condition, improve inspection accuracy, avoid dust affecting testing instruments, and ensure boiler performance, thus providing a guarantee for the safe and efficient operation of the boiler.
[0004] During the maintenance of long boilers, there is a problem of difficulty in reaching deep ash areas for cleaning. Due to the narrow and long internal space of the boiler, conventional cleaning tools cannot reach the deep ash accumulation, making it difficult to remove and affecting the boiler's thermal efficiency and normal operation. In existing technology, long-handled cleaning tools are used. By extending the length of the handle, it is possible to reach deep into the boiler, effectively solving the problem of cleaning tools being unable to penetrate deeply and cleaning deep ash accumulation in the boiler. However, in actual use, due to the limitations of the handle structure and operational flexibility, long-handled cleaning tools are difficult to perform multi-angle cleaning operations when facing complex corners inside the boiler, and cannot effectively and thoroughly clean the ash accumulation in the corners, affecting subsequent boiler inspection.

[0040] Working principle: The motor 3, which is fixedly connected to the top right side of the bracket 1, is started. The output end of the motor 3 engages with the rack on the front side of the slide rod 5, causing the slide rod 5 to slide forward in the groove 4 fixedly connected to the top rear side of the bracket 1. This allows the collection channel 14 and spray channel 10 connected to the top of the slide rod 5, as well as the spray head 12 at the end, to extend into the boiler. The water pump 6, which is fixedly connected to the top middle of the bracket 1, is started. The water pump 6 draws liquid from the outside and sends it to the steam engine 7 fixedly connected to the left side. The steam engine 7 converts the liquid into gas and delivers it to the spray head 12 at the end through the spray channel 10. The gas is sprayed in a concentrated manner and impacts the inner wall of the boiler, causing the dust to fall off from the inner wall. The collection pump 8, which is fixedly connected to the top of the collection box 9, is turned on. The collection pump 8 generates suction, and the dust enters the collection channel 14 from the collection port 13 and is then transported to the collection box 9 for storage by the collection pump 8. By rotating the joint 11 on the right side of the spray channel 10 to adjust the angle, the spray angle and direction of the spray head 12 can be flexibly changed, expanding the cleaning range and effectively removing dust from the complex corners of the boiler, thus completing the cleaning operation.
[0041] Furthermore, the bracket 1 is first moved to the side of the boiler, so that the rubber pad 201 fixedly connected to the top right side of the bracket 1 is placed between the machine and the boiler. The elastic cushioning performance of the rubber pad 201 is used to reduce the direct collision between the machine and the boiler. Then, the dust cover 202 is fixed to the right side of the rubber pad 201 by two bolts 204 threaded in the middle of its right side. During the fixing process, the gasket 205 fixedly connected to the outer wall of the bolt 204 prevents the bolt 204 from damaging the dust cover 202, ensuring that the dust cover 202 and the rubber pad 201 are firmly connected. The dust cover 202 forms a dust barrier to prevent dust from flying out when cleaning the inside of the boiler. The edge 203 fixedly connected to the outer wall of the dust cover 202 can prevent the dust cover 202 from hitting the boiler opening, thus achieving the purpose of protecting the machine, reducing dust escaping, and protecting the dust cover 202 and the boiler opening.
