Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to a dust removal device for preventing dust from being raised at a converter furnace mouth. Background Art

[0002] During the converter smelting process, a large amount of smoke and dust will be generated at the furnace mouth, which seriously affects the working environment and the health of workers. The circular bag dust collector is a high-efficiency air filtration equipment. Its main function is to filter dust, particulate matter and other pollutants in the air. This equipment is widely used in various industrial fields. The existing circular bag dust collector may have dust adhering to the inner wall of the dust collector, and there may also be too much dust deposited in the ash hopper. The deposition time is too long and condensed into blocks to block the ash discharge port.

[0003] The current publication number CN208742130U discloses a bag dust collector, including a box body, a support plate is placed horizontally in the box body, dust bags arranged in gaps are installed on the support plate, and the two sides of the dust bags lead to the inlet and outlet of the box body respectively; the inlet is arranged on the side wall of the box body below the support plate, and the outlet is arranged on the side wall of the box body above the support plate, and the bottom of the box body is provided with an ash discharge port; a plurality of covers made of heat-insulating materials are arranged on the outer wall of the box body above the support plate, and each of the covers is provided with an electric heating plate, and the outer side of the box body is coated with an insulation layer, and the cover is arranged in the insulation layer. The box body above the support plate is heated by the electric heating plate to increase the temperature of the box body itself, and an insulation layer is wrapped on the outside. The insulation layer is insulation cotton to slow down the heat dissipation of the box body, reduce the heat exchange between the box body and the flue gas, and avoid the problem of water vapor condensation caused by the decrease of flue gas temperature.

[0004] However, the above technology still has the following problems:

[0005] Although the above-mentioned water supply solves the problem of water vapor condensation caused by the decrease in flue gas temperature, after a long period of dust removal work, a lot of dust is easily adhered to the inner wall of the bag-type dust collector shell. At the same time, too much dust is deposited in the ash hopper. The deposition time is too long and the dust condenses into lumps, resulting in blockage of the ash outlet, which not only delays the dust removal work, but also reduces the dust removal effect.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 3 A dust removal device for preventing dust from being raised at a converter furnace mouth comprises a circular bag dust collector body 1. The circular bag dust collector body 1 comprises a shell 2. The shell 2 is divided into an upper clean chamber and a lower processing chamber. An ash hopper 3 is arranged below the processing chamber. A stirring mechanism 4 is arranged in the ash hopper 3. A cleaning mechanism 5 is arranged on the inner wall of the shell 2. The cleaning mechanism 5 is fixedly connected to the stirring mechanism 4.

[0021] The dust removal device for preventing dust from being raised at the furnace mouth of a converter in the utility model is similar in structure to the existing bag dust collector, such as the bag dust collector disclosed in the publication number CN208742130U. The main improvement of the utility model is that a stirring mechanism 4 is arranged in the dust collecting hopper 3, and a cleaning mechanism 5 is arranged on the inner wall of the shell 2. While the dust in the dust collecting hopper 3 is stirred, the scraper 503 cleans the inner wall of the shell 2. Figures 1 to 3 As shown, the dust removal device for preventing dust from rising at the mouth of the converter in the utility model starts the driving motor 401 after cleaning the dust at the mouth of the converter, and the driving motor 401 drives the rotating shaft 402 to rotate, so that the stirring blade 403 rotates, and the stirring blade 403 stirs the dust in the ash collecting hopper 3 to prevent the dust from being deposited too much and condensed into blocks for too long a deposition time, resulting in clogging of the ash discharge port, thereby affecting the discharge of dust. Since the cleaning mechanism 5 is connected to the rotating shaft 402 by the connecting rod 501, the connecting rod 501 not only rotates the cleaning mechanism 5, but also fixes the rotating shaft 402 to prevent the rotating shaft 402 from shaking when the dust is stirred. During the operation of the stirring mechanism 4, the cleaning mechanism 5 will also be rotated. At this time, the scraper 503 can clean the dust adhering to the inner wall of the shell 2, so that the dust falls into the ash collecting hopper 3 for collection, and is finally discharged together.

[0022] like Figure 2 As shown, the stirring mechanism 4 includes a driving motor 401 fixed on the upper surface of the shell 2, the output end of the driving motor 401 is fixedly connected to a rotating shaft 402, the front end of the rotating shaft 402 extends into the ash collecting hopper 3, and a plurality of stirring blades 403 are fixedly connected to the rotating shaft 402.

[0023] Specifically, after removing the dust from the converter furnace mouth, start the drive motor 401, which drives the rotating shaft 402 to rotate, thereby rotating the stirring blade 403, and stirring the dust in the ash hopper 3 to prevent excessive dust deposition and condensation into lumps, resulting in clogging of the ash discharge port, thereby affecting dust discharge.

[0024] like Figure 2 As shown, the cleaning mechanism 5 includes a plurality of connecting rods 501 fixedly connected to the rotating shaft 402, the front end of the connecting rod 501 is fixedly connected to an annular fixing block 502, the annular fixing block 502 is fixedly connected to a plurality of scrapers 503, and the upper end of the scraper 503 is fixedly connected to an annular tube 504.

[0025] Specifically, the cleaning mechanism 5 is connected to the rotating shaft 402 through the connecting rod 501. When the rotating shaft 402 rotates, the cleaning mechanism 5 rotates along the inner wall of the shell 2. During the rotation, the scraper 503 cleans the dust adhering to the inner wall of the shell 2, and the dust falls into the ash hopper 3 for easy discharge. The annular fixing block 502 and the annular tube 504 connect the scraper 503, so that the scraper 503 is always in a vertical state to maintain its stability. At the same time, the connecting rod 501 not only rotates the cleaning mechanism 5, but also fixes the rotating shaft 402 to prevent the rotating shaft 402 from shaking when the dust is stirred.

[0026] like Figure 2 As shown, the scraper 503 and the annular fixing block 502 are both in contact with the inner wall of the housing 2 .

[0027] Specifically, the scraper 503 and the annular fixing block 502 are both in contact with the inner wall of the housing 2 to ensure the cleaning effect of the scraper 503 on dust.

[0028] like Figure 3 As shown, the cross section of the scraper 503 is fan-shaped.

[0029] Specifically, no matter which direction the driving motor 401 rotates, it can be ensured that the scraper 503 can effectively clean the dust adhering to the inner wall of the shell 2.

[0030] like Figure 2 As shown, the surfaces of the rotating shaft 402 , the stirring blade 403 , the connecting rod 501 , the annular fixing block 502 , the scraper 503 and the annular tube 504 are all painted with dustproof paint.

[0031] Specifically, the dust-proof paint can effectively reduce dust adhesion on the surfaces of the rotating shaft 402 , the stirring blades 403 , the connecting rod 501 , the annular fixing block 502 , the scraper 503 and the annular tube 504 , thereby increasing the service life of the stirring mechanism 4 and the cleaning mechanism 5 .

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
