Description

Technical Field

[0001] The utility model relates to the technical field of flue gas diversion devices, and more specifically, the utility model relates to a boiler flue gas diversion device. Background Art

[0002] In modern industrial production, boilers, as important thermal energy power equipment, are widely used in various fields. During the operation of boilers, high-temperature flue gas is generated by combustion. However, the existing boiler flue designs are usually relatively simple, mostly consisting of a fixed flue gas pipeline. When in use, the flue gas is made to reach the designated area through the diversion pipeline, lacking effective flue gas diversion measures. This results in uneven flow velocity distribution of the flue gas in the flue, with high-speed airflows possibly occurring in local areas while the flow velocity is low in other areas, which brings many adverse effects to the performance and efficiency of the boiler. To solve the deficiencies of the existing technology, we propose a boiler flue gas diversion device. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the existing technology, the utility model provides a boiler flue gas diversion device to solve the problems that the flow velocity distribution of the flue gas in the flue is uneven, high-speed airflows may occur in local areas while the flow velocity is low in other areas, which brings many adverse effects to the performance and efficiency of the boiler.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A boiler flue gas diversion device includes a diversion frame, and a uniform diversion component is arranged inside the diversion frame, and a filtering and collecting component is arranged outside the uniform diversion component;

[0005] The uniform diversion component includes an L-shaped fixing plate, an electric telescopic rod is fixedly installed on the outer surface of the upper side of the L-shaped fixing plate, a connecting frame is fixedly installed on the outer surface of the telescopic end of the electric telescopic rod, a guide rail is slidably installed on the outer wall of the upper end of the connecting frame, a track groove is formed on the lower side of the connecting frame, a connecting block is slidably connected to the outer wall of the track groove, a hollow block is slidably installed on the outer wall of one side of the connecting block, a diversion grid is fixedly installed on the outer surface of one side of the hollow block, a spring column is arranged on the inner wall of one side of the diversion grid, and a scraping plate is fixedly installed on the outer surface of one end of the spring column.

[0006] Wherein, the L-shaped fixing plate and the guide rail are both fixedly installed on the outer surface of one side of the diversion frame, the connecting frame and the hollow block are both attached to the outer surface of one side of the diversion frame, the diversion grid is rotatably connected to the inner wall of the diversion frame, and the outer surface of the other end of the spring column is fixedly installed on the inner wall of one side of the diversion grid.

[0007] Among them, the filtering and collecting component includes an installation frame. An air hole is formed on the outer surface of one side of the installation frame. A filter plate is slidably installed on the inner wall of the other side of the installation frame. A fixing frame is fixedly installed on the outer surface of the upper side of the filter plate. A collecting box is arranged on the lower side of the installation frame. Trapezoidal blocks are symmetrically and fixedly installed on the outer surface of the upper side of the collecting box. The installation frame is fixedly installed on the inner wall of the diversion frame. The fixing frame is detachably installed on the outer surface of the upper side of the diversion frame. The trapezoidal blocks are slidably installed on the inner wall of the lower side of the diversion frame. The outer surface of the upper side of the collecting box is attached to the outer surface of the lower side of the diversion frame.

[0008] Among them, a connecting column is fixedly installed on the outer surface of one side of the hollow block.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] Through the uniformly guiding component provided by the present utility model, including the L-shaped fixing plate, when the electric telescopic rod is started to push the connecting frame to slide reciprocally along the guide rail, the connecting frame drives the connecting block to slide along the track groove when sliding, thereby driving the hollow block to rotate, and further driving the diversion grid to rotate. By using the above structure, by starting the electric telescopic rod to drive the diversion grid to rotate reciprocally inside the diversion frame, uniform diversion of the flue gas is achieved, so that the flow rate of the flue gas inside the diversion frame is uniform, avoiding the occurrence of high-temperature airflows locally, and thus greatly improving the performance and efficiency of the boiler;

[0012] Through the filtering and collecting component provided by the present utility model, including the installation frame, the flue gas generated by the boiler combustion reaches the filter plate through the air hole for flue gas filtration, intercepting the solid particles carried by the flue gas. At the same time, the rotation of the diversion grid makes the scraper slide along the outer surface of one side of the filter plate, scraping the solid particles on the surface of the filter plate and falling into the interior of the collecting box. By using the above structure, through the filter plate and the scraper sliding on the outer surface of one side of the filter plate, not only the filtration of the flue gas is realized, but also the cleaning of the filter plate is facilitated, avoiding the wear of the diversion frame by solid particles, and thus improving the service life of the device to a certain extent.

[0024] By starting the electric telescopic rod 22 to push the connecting frame 23 to slide reciprocally along the guide rail 24, the sliding of the connecting frame 23 drives the connecting block 26 to slide along the track groove 25, thereby driving the hollow block 27 to rotate, and further driving the diversion grid 28 to rotate, achieving uniform diversion of the flue gas, making the flow rate of the flue gas inside the diversion frame 1 uniform, and avoiding the occurrence of high-temperature gas flow locally.
