Description

Technical Field

[0001] The utility model relates to the technical field of soot filtration, in particular to a chimney pipe capable of filtering soot. Background Art

[0002] With the development of industrialization, many factories will inevitably generate flue gas and waste gas during the processing process, and heating furnaces in daily life usually also generate a large amount of thick smoke. We usually use chimney pipes to exhaust the smoke.

[0003] A chimney pipe is a structure used to discharge flue gas or waste gas generated by combustion. It is usually installed on the roof of a building or industrial facility, playing a role in guiding the flue gas discharge and protecting the building structure. Since most of the existing chimney pipes are straight cylindrical pipe structures, this transparent straight pipe chimney cannot filter the discharged soot when installing a filter plate inside. Therefore, after the flue gas is discharged into the air, it has a great impact on the air and is prone to causing environmental pollution. Therefore, the above technical problems need to be improved. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] Embodiment: Refer to Figures 1-3, A chimney pipe capable of filtering soot in the present utility model includes an upper smoke pipe 1 and a lower smoke pipe 5. The upper smoke pipe 1 is divided into a connecting part and a filtering part. A filter pipe 3 is arranged inside the filtering part of the upper smoke pipe 1. An external thread is provided on the outer wall of the filter pipe 3, and the filter pipe 3 is connected to the upper smoke pipe 1 through the external thread. A rotating rod 2 is longitudinally fixed at the outer end of the filter pipe 3, and the filter pipe 3 can be conveniently installed and disassembled through the rotating rod 2. An upright insect-proof board 4 is arranged at the outer end inside the filter pipe 3, and the insect-proof board 4 is connected to the filter pipe 3 through an adhesive strip. The use of the filtering device can be prevented from being affected by external insects through the insect-proof board 4. An internal thread is provided on the inner wall of the connecting part of the upper smoke pipe 1, and the lower smoke pipe 5 is connected to the upper smoke pipe 1 through a thread. A flange 6 is arranged at the bottom end of the lower smoke pipe 5. The installation and disassembly of the smoke pipe are facilitated through the flange 6.

[0018] In the present utility model, an inclined slot is opened at the upper part of one side wall of the lower smoke pipe 5. A dust collection box 7 is installed on the outer wall of the lower smoke pipe 5 at the outer end of the inclined slot. A dust guiding inclined plate 13 with an inner circle inclined upwards is fixedly connected to the inner wall of the lower smoke pipe 5 at the lower part of the inclined slot. The filtered soot can be prevented from falling into the smoke pipe and blocking the smoke pipe through the dust guiding inclined plate 13.

[0019] In the present utility model, the dust guiding inclined plate 13 is fixedly connected to the lower end of the inclined slot of the lower smoke pipe 5. A dust guiding port coinciding with the inclined slot is opened at the upper part of the inner end face of the dust collection box 7. A dust outlet 9 is opened at the bottom of the outer end face of the dust collection box 7. The soot is discharged through the dust outlet 9.

[0020] In the present utility model, a storage slot vertically penetrating the dust outlet 9 is opened on the top surface of the dust collection box 7. A baffle 8 for closing the dust outlet 9 is vertically inserted into the storage slot. The baffle 8 is of a T-shaped plate structure. The discharge of soot can be controlled through the baffle 8.

[0021] In the present utility model, a three-layer filtering structure is arranged inside the filter pipe 3. A filter plate 10 in the three-layer filtering structure is installed inside the inner end of the filter pipe 3. An adsorption plate 11 in the three-layer filtering structure is installed on one side inside the middle of the filter pipe 3. A layer of adsorption cotton is provided on the adsorption plate 11. An activated carbon plate 12 in the three-layer filtering structure is installed on the other side inside the middle of the filter pipe 3. The soot can be filtered through the three-layer filtering structure inside the filter pipe 3.

[0022] Working principle: When the present utility model is in use, first, the lower smoke pipe 5 is connected to other smoke pipes through the flange 6, and the filter pipe 3 is installed inside the upper smoke pipe 1. When the smoke enters from inside the smoke pipe, the smoke reaches the upper smoke pipe 1 through the lower smoke pipe 5 and enters the filter pipe 3. First, a part of the soot is filtered through the filter plate 10 of the filter pipe 3. After the soot reaches the adsorption plate 11, the cross-shaped adsorption cotton on the adsorption plate 11 absorbs the soot. Finally, the soot is purified through the activated carbon plate 12 and then discharged from the holes opened on the insect-proof board 4. The filtered soot will fall from the upper smoke pipe 1 onto the dust guiding inclined plate 13 and be discharged from the dust collection box 7 along the inclined slot.

[0023] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
