Description

Technical Field

[0001] The utility model relates to the technical field of boiler ash cleaning, in particular to a ash cleaning device and a boiler. Background Art

[0002] The power plant boiler is a device used to generate electricity in a thermal power plant. Specifically, the boiler uses fuel combustion to convert liquid water into steam, and uses the steam to drive the turbine to rotate, converting thermal energy into mechanical energy. The turbine then drives the generator to move, converting mechanical energy into electrical energy to reserve electricity for the city. However, the exhaust gas and smoke generated by the combustion of fuel in the boiler will adhere to the inner wall of the boiler and need to be cleaned regularly.

[0003] Manual cleaning will waste unnecessary manpower, take a long time, have low cleaning efficiency, and cannot centrally process the dust after cleaning, which will reduce the service life of the boiler. The flying dust during cleaning will also harm the health of the staff.

[0004] Therefore, the prior art discloses a ash cleaning structure for a thermal power plant boiler, such as Figure 1 As shown, the first drive motor 01 drives the threaded rod 02 to move up and down, and the second drive motor 03 is fixed to the end of the threaded rod 02 away from the first drive motor 01. The second drive motor 03 is connected to a fixed block 04. The second drive motor 03 drives the fixed block 04 to rotate. A sliding groove 05 is provided at the end of the fixed block 04. A sliding block 07 is fixed in the sliding groove 05 by a spring 06. A brush 08 is fixed to the other end of the sliding block 07, and the brush 08 cleans the inner wall of the boiler 09.

[0005] In the above-mentioned cleaning structure, the sliding block 07 provides a squeezing force on the inner wall of the boiler 09 through the spring 06, so that the brush 08 fits tightly with the inner wall of the boiler 09. However, when the inner diameter of the boiler 09 is large, the elastic force of the spring 06 is small, the squeezing force provided by the sliding block 07 is small, and the cleaning is not sufficient; when the inner diameter of the boiler 09 is small, the elastic force of the spring 06 is large, and the squeezing force provided by the sliding block 07 is large. During the cleaning, the brush 08 and the inner wall of the boiler 09 are prone to friction, causing the inner wall to become thinner; or the elastic force provided by the existing spring 06 cannot meet the contact between the brush 08 and the inner wall of the boiler 09, and the inner wall of the boiler 09 cannot be cleaned. Therefore, for boilers 09 with different inner diameters, springs 06 of different sizes still need to be selected in actual use to adapt to boilers 09 with different inner diameters, which is inconvenient to use.

The second motor drives the second fixing part 52 to rotate inside the boiler body 1, thereby driving the cleaning brush 31 to rotate and remove dust from the inner wall of the boiler body 1; the third motor drives the screw rod to rotate, thereby driving the first fixing part 4 to rise and fall on the screw rod, changing the height of the cleaning brush 31, and realizing comprehensive cleaning of the inner wall of the boiler body 1; the exhaust device sucks the cleaned dust into the collection box 323 through the connecting pipe 322.

[0096] The installation method of the boiler in this embodiment is as follows:

[0097] Step 1: Place the cover plate 7 on the top of the boiler body 1;

[0098] Step 2: Pull the limiting member 82 downward to separate the limiting member 82 from the second accommodating space 71. At this time, the spring is compressed;

[0099] Step 3: Push the adjusting member 8 inward so that the first end of the adjusting member 8 is inserted into the first accommodating space 11. At this time, the slider 84 slides in the slide groove 72.

[0100] Step 4: Loosen the limiting member 82 . Under the elastic force of the spring, the limiting member 82 is plugged into the corresponding second accommodating space 71 , thereby fixing the cover plate 7 and the boiler body 1 .

[0101] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
