Description

Technical Field

[0001] The utility model relates to the field of boiler flues, in particular to an anti-corrosion sludge boiler flue. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The hot water or steam generated in the boiler can directly provide the heat energy required for industrial production and people's livelihood.

[0003] The flue is the main way for the boiler to discharge flue gas. At present, during the long-term discharge of flue gas by the flue, dust in the flue gas will adsorb on the inner wall of the flue to generate dirt. However, it is difficult to clean the adsorbed dirt in the current flue. And the dirt adsorbed on the inner wall of the flue for a long time is likely to cause corrosion to the flue, thereby affecting the service life of the flue. For this reason, we propose an anti-corrosion sludge boiler flue to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-corrosion sludge boiler flue to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A support plate is fixedly connected to the inner circle of the chimney flue. A bearing is fixedly embedded on the upper surface of the support plate. A rotating rod is fixedly connected to the inner circle of the bearing. Two connecting blocks are fixedly connected to the outer surface of the rotating rod. Two high-temperature resistant cleaning brush plates are fixedly connected to the mutually remote side surfaces of the two connecting blocks. The mutually remote side surfaces of the two high-temperature resistant cleaning brush plates are both in contact with the inner circle of the chimney flue. A communicating pipe is arranged on the left side of the chimney flue. A threaded connection ring is fixedly connected to the outer surface of the chimney flue. A sealing cover is threadedly connected to the outer surface of the threaded connection ring.

[0007] In a further embodiment, an annular limiting plate is fixedly connected to the outer surface of the chimney flue. The top end of the sealing cover is in contact with the bottom surface of the annular limiting plate.

[0008] In a further embodiment, a first flange is fixedly communicated with the left end of the chimney flue. A plurality of first connection holes are opened on the left side surface of the first flange.

[0009] In a further embodiment, a second flange is fixedly communicated with the right end of the communicating pipe. A plurality of second connection holes are opened on the right side surface of the second flange.

[0011] In a further embodiment, a plurality of rotating blocks are fixedly connected to the outer surface of the sealing cover, and a warning sign is fixedly connected to the front surface of the chimney duct.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the anti-corrosion layer sprayed inside the chimney duct, the inner wall of the chimney duct can have high-efficiency anti-corrosion performance. At the same time, by using the support plates, bearings and rotating rods arranged inside the chimney duct, and in cooperation with the connecting blocks and the two high-temperature cleaning brush plates, the two high-temperature cleaning brush plates can clean the inner wall of the chimney duct, causing the soot and dirt to slide downwards, thereby facilitating the cleaning of the dirt adsorbed inside the chimney duct, solving the problem that the dirt adsorbed on the inner wall of the flue for a long time is likely to cause corrosion to the chimney duct, and enabling the chimney duct to be better used for anti-corrosion.

A communicating pipe 14 is provided on the left side of the chimney duct 1. A threaded connection ring 8 is fixedly connected to the outer surface of the chimney duct 1. A sealing cover 9 is threadedly connected to the outer surface of the threaded connection ring 8. Through the setting of the threaded connection ring 8, the sealing cover 9 can seal the bottom of the chimney duct 1, which will make the flue gas flow upward better. Through the cooperation of the rotating rod 5, the connecting blocks 6 and the two high-temperature resistant cleaning brush plates 7, the two high-temperature resistant cleaning brush plates 7 can clean the inner wall of the chimney duct 1, achieving the effect of cleaning the inside of the chimney duct 1.

[0023] In a further embodiment, an annular limiting plate 10 is fixedly connected to the outer surface of the chimney duct 1. The top end of the sealing cover 9 is in contact with the bottom surface of the annular limiting plate 10. The left end of the chimney duct 1 is fixedly communicated with a first flange 12. A plurality of first connection holes 13 are formed in the left side surface of the first flange 12. The right end of the communicating pipe 14 is fixedly communicated with a second flange 15.
