Description

Technical Field

[0001] This utility model belongs to the field of coal-fired power plant boiler furnace cleaning technology, specifically a simple ash removal tool for coal-fired power plant boiler furnaces. Background Technology

[0002] During operation, slagging on the water-cooled walls of the furnace is a common phenomenon in coal-fired power boilers. Ash accumulation on the heating surfaces affects heat transfer, increases flue gas temperature, and reduces boiler efficiency. Therefore, it is necessary to remove ash regularly to ensure the safe and economical operation of the boiler.

[0003] The existing method of manually cleaning and removing coking deposits from the inner wall of the furnace of coal-fired power generation boilers using tools such as decoking hammers, decoking shovels, and decoking hooks is labor-intensive and inefficient. Therefore, we propose a simple ash removal tool for the furnace of coal-fired power generation boilers. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a simple ash removal tool for the furnace of a coal-fired power generation boiler. It effectively solves the problem that the existing method of manually cleaning and peeling off the coking bodies on the inner wall of the furnace of a coal-fired power generation boiler by means of tools such as decoking hammers, decoking shovels, and decoking hooks is labor-intensive and inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple ash removal tool for the furnace of a coal-fired power generation boiler, applied to the body of the coal-fired power generation boiler. A support mechanism is connected to one side of the surface of the coal-fired power generation boiler body. An ash removal mechanism is inserted inside the support mechanism. The ash removal mechanism includes a main support rod, which is movably locked in the middle of the support mechanism. Several secondary support rods are provided at the tail end of the main support rod. A limiting frame is provided on the side of the main support rod away from the secondary support rods. Several movable rods are evenly locked in a ring on the inner side of the limiting frame. A scraper is inserted into the end of the movable rod away from the limiting frame. The movable rod and the scraper are connected by bolts. A guide rod is fixed to the middle of the surface of the limiting frame. An electric push rod is connected to the end of the guide rod away from the limiting frame.

[0006] Preferably, the main support rod and the auxiliary support rod are connected by a thread, and the main support rod and the auxiliary support rod have a number of uniformly spaced toothed grooves on their local surfaces.

[0007] Preferably, the movable rod can rotate freely inside the limiting frame, and when the main support rod is in contact with the limiting frame, both sides of the movable rod surface are in close contact with the main support rod and the limiting frame surface, respectively.

[0008] Preferably, the guide rod is T-shaped, the electric push rod is fitted inside the main support rod, and the guide rod and the main support rod form a locking and sliding structure through the electric push rod.

[0009] Preferably, the support mechanism includes a limiting ring frame, with several connecting rods evenly distributed in a ring shape on the outer side of the limiting ring frame, and a positioning flange plate fixed to the end of each connecting rod away from the limiting ring frame.

[0010] Preferably, the inner wall of the limiting ring frame matches and fits the outer walls of the main support rod and the auxiliary support rod. The limiting ring frame is integrally formed with the positioning flange plate through several connecting rods. The positioning flange plate is connected to the body of the coal-fired power generation boiler.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The threaded connection between the main support rod and the auxiliary support rod allows for the addition or reduction of auxiliary support rods as needed. This facilitates flexible adjustment of the overall rod length based on the actual depth of the furnace, adapting to different specifications of coal-fired power generation boiler bodies. When the movable rod and scraper are in a folded and stowed state, they can be easily inserted into the coal-fired power generation boiler body. Then, the electric push rod effectively drives the guide rod to retract, thereby unfolding several movable rods and scrapers. This allows the scrapers to fit into the furnace of the coal-fired power generation boiler body. Afterward, horizontal movement and rotation of the rod body can achieve multi-directional coke removal and ash cleaning. The scraper can be detached by removing the bolts, facilitating the replacement of scrapers of different specifications and improving the adaptability of ash cleaning.

[0013] 2. The design of the inner wall of the limiting ring frame matching and fitting with the outer walls of the main and auxiliary support rods can form a precise circumferential limiting for the rods of the ash cleaning mechanism. This effectively prevents the main and auxiliary support rods from shaking or shifting due to force during the ash cleaning process, ensuring that the ash cleaning mechanism always runs along the preset trajectory, improving the accuracy of the ash cleaning operation. At the same time, it prevents accidental bumping damage to the inner wall of the coal-fired power plant body caused by the shaking of the rods. The direct connection between the positioning flange plate and the coal-fired power plant body realizes the firm fixation of the support mechanism and the coal-fired power plant body, providing a stable installation benchmark for the ash cleaning mechanism. After the ash cleaning is completed, the support mechanism and the ash cleaning mechanism can be removed from the coal-fired power plant body, and the inspection port on one side of the coal-fired power plant body can be sealed.

[0022] Please see Figure 1-4A simple ash removal tool for the furnace of a coal-fired power plant boiler is applied to the boiler body 1. A support mechanism 2 is connected to one side of the boiler body 1. An ash removal mechanism 3 is inserted inside the support mechanism 2. The ash removal mechanism 3 includes a main support rod 301, which is movably locked inside the middle of the support mechanism 2. Several auxiliary support rods 302 are provided at the tail end of the main support rod 301. The main support rod 301 and the auxiliary support rods 302 are connected by threads. Several toothed grooves are evenly opened in a ring on the partial surfaces of the main support rod 301 and the auxiliary support rods 302. A limiting frame 303 is provided on the side away from the secondary support rod 302. Several movable rods 304 are evenly and circularly secured inside the limiting frame 303. Furthermore, the movable rods 304 can rotate freely inside the limiting frame 303. When the main support rod 301 and the limiting frame 303 are in contact, both sides of the surface of the movable rods 304 are in close contact with the surfaces of the main support rod 301 and the limiting frame 303, respectively. A scraper 305 is inserted into the end of the movable rod 304 away from the limiting frame 303. The movable rod 304 and the scraper 305 are connected by bolts 306. The limiting frame 303... A guide rod 307 is fixedly connected to the middle of the surface. An electric push rod 308 is connected to the end of the guide rod 307 away from the limiting frame 303. Furthermore, the guide rod 307 is T-shaped, and the electric push rod 308 is fitted inside the main support rod 301. The guide rod 307 and the main support rod 301 form a locking and sliding structure through the electric push rod 308. The design of the threaded connection between the main support rod 301 and the auxiliary support rod 302 allows for the addition or reduction of the auxiliary support rod 302 as needed, facilitating flexible adjustment of the overall rod length according to the actual depth of the furnace, and adapting to different specifications of coal-fired generators. When the movable rods 304 and scraper 305 are in a folded and stored state, they can be easily inserted into the coal-fired power plant body 1. Then, the electric push rod 308 effectively drives the guide rod 307 to retract, thereby unfolding several movable rods 304 and scraper 305, making it easier for the scraper 305 to fit into the furnace of the coal-fired power plant body 1. After that, horizontal movement and rotation of the rods can achieve multi-directional coke removal and ash cleaning. The scraper 305 can be detached by removing the bolts 306, which facilitates the replacement of scraper 305 of different specifications and improves the adaptability of ash cleaning.

The inner wall of the limiting ring frame 201 matches and fits against the outer walls of the main support rod 301 and the auxiliary support rod 302. The limiting ring frame 201 is integrally formed with the positioning flange plate 203 via the connecting rods 202. The positioning flange plate 203 is connected to the coal-fired power plant body 1. Through the design of the inner wall of the limiting ring frame 201 matching and fitting against the outer walls of the main support rod 301 and the auxiliary support rod 302, a precise circumference can be formed around the rods of the ash removal mechanism 3. The limiting mechanism effectively prevents the main support rod 301 and the auxiliary support rod 302 from shaking or shifting due to force during the ash cleaning process, ensuring that the ash cleaning mechanism 3 always runs along the preset trajectory, improving the accuracy of the ash cleaning operation, and preventing accidental bumping damage to the inner wall of the coal-fired power plant body 1 caused by the shaking of the rods. The direct connection between the positioning flange plate 203 and the coal-fired power plant body 1 realizes the firm fixation of the support mechanism 2 and the coal-fired power plant body 1, providing a stable installation benchmark for the ash cleaning mechanism 3. After the ash cleaning is completed, the support mechanism 2 and the ash cleaning mechanism 3 can be removed from the coal-fired power plant body 1, and the inspection port on one side of the coal-fired power plant body 1 can be sealed.
