Description

Technical Field

[0001] The invention relates to the field of dust cleaning, in particular to a dust removal device for glass fiber production. Background Art

[0002] The dust removal device for glass fiber production is a device specially designed to deal with the dust generated in the glass fiber production process. It can effectively remove dust particles generated during production and processing as well as dust particles in the environment, ensuring the cleanliness of the production environment and the health of workers. It is widely used in various glass fiber production occasions.

[0003] For example, the Chinese patent with publication number CN112934901A discloses "a dust collector for glass fiber production, which includes a casing, an exhaust fan and a filter box, the side walls of the filter box are covered with ventilation slots, the inner wall of the filter box is provided with a filter layer, and the bottom of the filter box is a dust hopper". Although it can play the role of "the inner surface of the entire filter box of this dust collector becomes a filter surface, the filter area is significantly increased compared with the single filter screen method in the prior art, and the filter layer cleaning step can also be performed. It is used in glass fiber production workshops or connected to the exhaust port of production equipment to purify the production environment and ensure the health of workers". However, when the dust removal device for glass fiber production is used, the air does not flow evenly during the circulation process, and the filter cannot contact the air evenly, resulting in reduced filtering effect. After the filter filters the air to remove dust particles, the filtered dust particles will accumulate on the filter. The accumulation of dust particles will gradually reduce the air circulation effect of the filter, and then continue to reduce the filtering effect of the filter. Therefore, the filter needs to be replaced regularly, which also brings inconvenience to the filtering use of the device. At the same time, dust particles accumulate on the filter. When the filter is replaced to collect dust particles, the dust particles will be shaken into the air, resulting in further pollution of the environment. Therefore, the collection of dust particles is also inconvenient. Summary of the invention

[0038] In this embodiment, the brush rod structure 27 includes a rotating brush rod 28, bristles 29, a driven pulley 30, a driving pulley 31 and a transmission belt 32. The two rotating brush rods 28 are movably installed inside the dust collecting box 22, the bristles 29 are fixedly sleeved on the outside of the rotating brush rods 28, the driven pulley 30 is fixedly installed at one end of the rotating brush rod 28, the driving pulley 31 is movably installed inside the dust collecting box 22 and is located below the rotating brush rod 28, and the transmission belt 32 is sleeved on the outside of the driven pulley 30 and the driving pulley 31.

[0039] In this embodiment, the rotating shaft of the brush rod motor 26 is inserted into the dust collecting box 22 and fixedly connected to the driving pulley 31. The driven pulley 30 and the driving pulley 31 rotate synchronously through the transmission belt 32. The bristles 29 are located in the dust collecting port 33 and are closely connected to the annular filter 14. The driving pulley 31 is driven to rotate by the brush rod motor 26, and the driven pulley 30 is driven to rotate through the transmission belt 32.

[0040] In this embodiment, a dust collecting port 33 is provided at the bottom of the dust collecting box 1, and the dust collecting port 33 is located above the dust collecting box 22. A dust collecting drawer 24 is movably installed inside the dust collecting box 22, and the dust collecting drawer 24 is located below the bristles 29. A drawer handle 25 is fixedly installed at the front end of the dust collecting drawer 24. The front and rear ends of the dust collecting box 22 are located above the dust collecting drawer 24 and are embedded with exhaust filters 23.

[0041] It should be noted that the present invention is a dust removal device for glass fiber production. When in use, the device is placed in a glass fiber production workshop, and the dust removal air inlet 10 in front of the dust collection box 1 is aligned with the glass fiber production and processing position, and the exhaust fan 4 on the exhaust box 3 is operated to generate negative pressure in the exhaust box 3 for exhaust, and then the exhaust box 3 sucks air from the filter element installation box 18, so that negative pressure is generated in the filter element installation box 18 and the suction box 16, and then the front end of the suction box 16 intakes air, so that the dust and air generated by the glass fiber production and processing enter the dust collection box 1 through the dust removal air inlet 10 in front of the dust collection box 1, and the air first passes through the annular filter screen 14 and then enters the suction box 16 to filter the dust in the air, and then the air enters the filter element installation box 18, and then passes through the air filter 19 in the filter element installation box 18 for filtering and dust removal again, and the filtered air enters the exhaust box 3 and is discharged from the exhaust pipe 5, thereby completing the dust removal during the glass fiber production and processing;

[0042] When the annular filter 14 filters and removes dust from the air, the driving gear 7 is driven to rotate by the operation of the rotating drive motor 6, and the driving gear 7 drives the first rotating clamp ring 11 to rotate by meshing with the transmission gear 12, so that the first rotating clamp ring 11 and the second rotating clamp ring 13 rotate around the interior of the dust collection box 1, and also drive the annular filter 14 to rotate. Therefore, when the air passes through the dust removal air inlet 10 and is filtered by the annular filter 14, the circulating annular filter 14 can evenly contact the air for filtering and dust removal, thereby achieving uniform filtering and dust removal, and preventing the problem of partial filtering of the annular filter 14 from occurring;

[0043] When the annular filter 14 rotates to filter and remove dust, the annular filter 14 rotates clockwise. Therefore, after the annular filter 14 filters the air at the dust removal air inlet 10, the dust in the air accumulates on the outside of the annular filter 14. Then, the annular filter 14 carrying the dust rotates clockwise to the position of the dust collection port 33 below. The operation of the brush rod motor 26 drives the driving pulley 31 to rotate. The driving pulley 31 then drives the driven pulley 30 and the rotating brush rod 28 to rotate through the transmission belt 32, thereby causing the rotating brush rod 2 The bristles 29 on the outside of 8 rotate continuously, and the bristles 29 rotate and clean the annular filter 14 in the dust collecting port 33, and brush away the dust accumulated on the annular filter 14, so that the dust falls downward to the dust collecting drawer 24 for collection. After the dust on the annular filter 14 is brushed away, it rotates again to the dust removal air inlet 10 for air filtering, preventing the annular filter 14 from being blocked by dust, so that the annular filter 14 always maintains a clean state when filtering the air, and the cycle is repeated in sequence to improve the long-term filtering and dust removal effect;

[0044] When the air is exhausted from the suction box 3, the filtered air is exhausted through the exhaust pipe 5, and the exhaust pipe 5 is connected to the air supply pipe 8, so that part of the air enters the air supply pipe 8, and then is ejected from the jet pipe 9 at the lower end of the air supply pipe 8. The air ejected from the jet pipe 9 is blown downward on the inner side of the annular filter 14, and the blowing air is located above the dust collecting port 33. Therefore, when the annular filter 14 moves to the top of the dust collecting port 33, the air is blown from the inner side of the annular filter 14 to blow the dust carried on the outer side downward, so as to improve the efficiency of separating the dust from the annular filter 14 and more thoroughly remove the dust from the annular filter 14.

[0045] The annular filter 14 can always keep the air in a clean state during filtering, reduce the filtering pressure of the second filtering air filter 19, so that the air filter 19 can also be used for filtering for a long time. While improving the filtering effect, the service life of the air filter 19 is also increased, so that the device can be used for filtering and dust removal for a long time. After the filter installation cover 21 on the second side plate 20 is opened, the air filter 19 can also be quickly disassembled and replaced.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
