Technical Field

[0001] The utility model relates to the field of hot blast stoves, and specifically to a ventilation duct for a hot blast stove capable of deodorizing. Background Art

[0002] At present, hot blast stoves are widely used as heat sources in baking rooms for agricultural products such as tobacco leaves and vegetables. Its working principle is: biomass fuel is conveyed to the furnace chamber of the hot blast stove by a feeding device for combustion, the flame heats the air in the heat exchanger to generate hot air, and the hot air is conveyed to the baking room to provide heat for the baking work. The air generated by the combustion of the fuel in the hot blast stove usually contains harmful gases such as sulfides, so it has a relatively strong odor. Currently, a filter plate is usually arranged in the exhaust duct of the hot blast stove to filter the gas discharged from the hot blast stove, but there are problems that it is inconvenient to install and replace, and when replacing the filter plate, the hot blast stove needs to be stopped, thus causing inconvenience to production.

It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0016] Embodiment 1

[0017] As Figure 1-2 shown, this embodiment provides a ventilation pipe for deodorizing used in a hot blast stove, which includes a pipe body 110. A pipe through-hole 120 penetrating the pipe is provided in the pipe body 110. A filter plate mounting seat 130 is slidably provided in the pipe through-hole 120; a partition 210 is provided in the filter plate mounting seat 130. The partition 210 divides the inner cavity of the filter plate mounting seat 130 into filter plate mounting cavities 220 of the same size. An activated carbon filter plate 230 is provided in the filter plate mounting cavity 220. In this embodiment, in order to realize the installation of the activated carbon filter plate 230, a plurality of strip-shaped openings 170 are provided at the filter plate mounting cavity 220 in the filter plate mounting seat 130. A card slot 240 for installing the activated carbon filter plate 230 is provided at the strip-shaped opening 170 in the filter plate mounting cavity 220.

[0018] An exhaust hole 140 communicating with the filter plate mounting cavity 220 is provided at the filter plate mounting seat 130; both ends of the filter plate mounting seat 130 along its sliding direction and the partition plate 210 can seal the pipeline through hole 120; a fixing mechanism for fixing the filter plate mounting seat 130 is further included. The fixing mechanism includes cover plates 150 arranged at both ends of the filter plate mounting seat 130 along its sliding direction. A handle 160 is provided at the outer end face of the cover plate 150, and the cover plate 150 is bolted to the outer side wall of the pipeline body 110.

[0019] During use, the activated carbon filter plate 230 is installed in the filter plate mounting cavity 220 on this side through the strip-shaped opening 170 on one side of the filter plate mounting seat 130. Then, the filter plate mounting cavity 220 on this side is pushed into the pipeline body 110, and then the filter plate mounting seat 130 is fixed by the bolt connection between the cover plate 150 and the side wall of the pipeline body 110. When the activated carbon filter plate 230 needs to be replaced, first, the activated carbon filter plate 230 is installed in the filter plate mounting cavity 220 on the other side through the strip-shaped opening 170 on the other side of the filter plate mounting seat 130. Then, the cover plate 150 is loosened, and the filter plate mounting cavity 220 with the newly installed activated carbon filter plate 230 is pushed into the pipeline body 110. At this time, the activated carbon filter plate 230 to be replaced is pushed out of the pipeline body 110, and the activated carbon filter plate 230 can be taken out through the strip-shaped opening 170 for replacement.

[0020] In this embodiment, through the arrangement of the slidable filter plate mounting seat 130, the installation of the activated carbon filter plate can be realized by sliding the filter plate mounting seat 130, and at the same time, the activated carbon filter plate to be replaced can also be slid out by sliding the filter plate mounting seat 130, thus facilitating the installation of the activated carbon filter plate.

[0021] Combined Figure 3 As shown, a slide rail 310 arranged along the sliding direction of the filter plate mounting seat 130 is provided in the pipeline body 110, and a slider 320 for cooperating with the slide rail 310 is provided at the filter plate mounting seat 130. Baffles 330 are provided on both sides of the filter plate mounting seat 130 in the pipeline body 110 for sealing the gap between the slider 320 at the filter plate mounting seat 130 and the pipeline through hole 120.

[0022] In this embodiment, through the cooperation between the slide rail 310 and the slider 320, the stability of the filter plate mounting seat 130 during sliding can be better improved. Through the arrangement of the baffle 330, the air in the pipeline body 110 is prevented from escaping from the gap between the slider 320 and the pipeline through hole 120, thus better improving the stability of the ventilation pipeline for deodorizing the energy consumption of the hot blast stove during use.

[0023] The specific working principle of the ventilation pipeline for deodorizing the energy consumption of the hot blast stove in this embodiment is as follows:

[0024] In use, the activated carbon filter plate 230 is installed in the filter plate installation cavity 220 on this side through the strip-shaped opening 170 on one side of the filter plate mounting seat 130. Subsequently, the filter plate installation cavity 220 on this side is pushed into the pipe body 110, and then the filter plate mounting seat 130 is fixed by the bolt connection between the cover plate 150 and the side wall of the pipe body 110.

[0025] During operation, air enters one side of the pipe body, enters the filter plate installation cavity 220 through the exhaust hole 140 on one side of the filter plate mounting seat 130, and is discharged from the exhaust hole 140 on the other side of the filter plate mounting seat 130 after being filtered by the activated carbon filter plate 230 in the filter plate installation cavity 220.

[0026] When the activated carbon filter plate 230 needs to be replaced, first install the activated carbon filter plate 230 in the filter plate installation cavity 220 on this side at the strip-shaped opening 170 on the other side of the filter plate mounting seat 130. Subsequently, loosen the cover plate 150 and push the filter plate installation cavity 220 with the new activated carbon filter plate 230 installed into the pipe body 110. At this time, the activated carbon filter plate 230 to be replaced is pushed out of the pipe body 110, and the activated carbon filter plate 230 can be taken out through the strip-shaped opening 170 for replacement.

[0027] In summary, the above are only the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
