Problems solved by technology

At present, the chimney mainly relies on the installation of cylindrical air filter elements to purify and filter the smoke and dust in the exhaust gas to reduce air pollution. However, during the use of the cylindrical air filter element, it needs to be cleaned regularly. Generally, the height is high, the cleaning of the air filter is difficult, time-consuming and labor-intensive, and the danger of working at heights is high

Embodiment 1

[0020] Such as Figure 1-3 As shown, a self-cleaning dust filter chimney includes a chimney body 1, an annular sealing plate 2 is fixedly connected in the chimney body 1, a cylindrical filter element 3 is fixedly connected in the annular sealing plate 2, and a ring-shaped filter element 3 is arranged in the cylindrical filter element 3. Plate 4, the side wall of the annular plate 4 is embedded with a plurality of dust suction branch pipes 5, the input end of the dust suction branch pipe 5 is in contact with the inner side wall of the cylindrical filter element 3, and the inner side wall of the cylindrical filter element 3 is slidingly sealed and connected with a dust suction pipe. Main pipe 6, the output ends of a plurality of dust suction branch pipes 5 are all connected with dust suction main pipe 6, and the output ends of dust suction branch pipes 5 are arc-shaped, and match with the side wall of annular plate 4 (such as image 3 As shown), the upper side of the chimney bod...

Embodiment 2

[0024] Such as Figure 4-5 As shown, the difference between this embodiment and Embodiment 1 is that: the lower end of the dust suction main pipe 6 is sealed and rotatably connected with a rotating pipe 12, and the output ends of a plurality of dust suction branch pipes 5 are connected to the dust suction main pipe 6 through the rotating pipe 12 Generally speaking, the dust suction branch pipe 5 is in the shape of fan blades, and the plurality of dust suction branch pipes 5 are evenly distributed around the center of the ring plate 4. It should be noted that the windward side of the wind wheel composed of a plurality of dust suction branch pipes 5 faces downward.

[0025] In this embodiment, since the plurality of dust suction branch pipes 5 are in the shape of fan blades, the smoke and dust will drive the ring plate 4 to rotate during the discharge process, thereby cleaning the cylindrical filter element 3 more comprehensively.

Abstract

The invention belongs to the field of chimneys, and particularly relates to a self-cleaning dust filtering chimney, comprising a chimney body; an annular sealing plate is fixedly connected in the chimney body; a cylindrical filter element is fixedly connected in the annular sealing plate; the cylindrical filter element is internally provided with an annular plate; a plurality of dust suction branch pipes are embedded on the side wall of the annular plate; the input ends of the dust collection branch pipes are in abutting contact with the inner side wall of the cylindrical filter element; a dust collection main pipe is slidably and sealingly connected in the cylindrical filter element; the output ends of the plurality of dust collection branch pipes communicate with the dust collection mainpipe; the upper side of the chimney body is provided with a conical rain shielding plate, a conical cavity is arranged in the rain shielding plate, the upper end of the dust collection main pipe extends into the conical cavity and is fixedly connected with the rain shielding plate, the upper end edge of the dust collection main pipe is turned outwards to form a dust shielding ring, the upper endof the conical cavity is provided with an opening, and the opening is internally and fixedly connected with an unpowered wind ball. The self-cleaning dust filtering chimney provided by the invention can suck and clean the filter element continuously by using the wind power, and then the service period of the filter element can be prolonged.

Description

technical field [0001] The invention belongs to the field of chimneys, in particular to a self-cleaning dust filtering chimney. Background technique [0002] Chimney is an important facility to reduce air pollution in the process of exhaust gas emission. At present, the chimney mainly relies on the installation of cylindrical air filter elements to purify and filter the smoke and dust in the exhaust gas to reduce air pollution. However, during the use of the cylindrical air filter element, it needs to be cleaned regularly. Generally, the height is high, and the cleaning of the air filter element is difficult, time-consuming and labor-intensive, and the risk of working at heights is relatively high. [0003] For this reason, we propose a self-cleaning dust filter chimney to solve the above problems. Contents of the invention [0004] The object of the present invention is to solve the above problems and provide a self-cleaning dust filter chimney that utilizes wind force ...
