[0002] Dust removal refers to dusty industrial waste gas or generated from mechanical processes such as crushing, screening, conveying, blasting of solid materials, or generated from combustion, high-temperature melting and chemical reactions. The former contains dust with large particle size and the same chemical composition as the original solid material, while the latter contains smoke with small particle size and chemical properties different from the material that generated it. Improving production processes and combustion technology can reduce the generation of particulate matter. Dust collectors are widely used to control dust and smoke that have already been generated.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a new type of dust removal equipment, including a shell 1, a fixing plate 2 is fixed inside the shell 1, a through hole 3 is opened on the fixing plate 2, a first sealing ring 4 is fixed to the inner wall of the through hole 3, a fixing cylinder 5 is penetrated inside the first sealing ring 4, a cylindrical filter screen 6 is fixed to the bottom of the fixing cylinder 5, a groove 7 is opened inside the fixing cylinder 5, a through groove 8 is opened on the top of the inner side of the groove 7 above the fixing plate 2, a threaded hole 9 is opened on the top of the shell 1, the inner side of the threaded hole 9 is threadedly connected to the outer side of the top of the fixing cylinder 5, and a cleaning mechanism is arranged on the fixing plate 2.

[0026] The cleaning mechanism includes a fixed plate 2, on the inner side of which a rotating shaft 10 is rotatably mounted via a bearing, the lower end of the rotating shaft 10 passes through the inside of the side of an outer ring 11, an inner ring 12 is fixed to the inner side of the outer ring 11, a brush 13 is fixed to the inner side of the inner ring 12, the brushes 13 are distributed at equal angles about the central axis of the inner ring 12, the ends of the brushes 13 are in contact with the outer side of the cylindrical filter screen 6, the upper end of the rotating shaft 10 is located above the fixed plate 2 and a gear 14 is fixed thereon, a gear ring 15 is rotatably mounted on the inner side of the outer shell 1 through a bearing, the inner side of the gear ring 15 is meshedly connected with the outer side of the gear 14, a servo motor 16 is fixed to the top of the outer shell 1, and the output end at the bottom of the servo motor 16 is fixedly connected to the center of the top of the gear 14.

[0027] An anti-slip plate 17 is fixed to the bottom of the rotating shaft 10 , and the anti-slip plate 17 and the lower end of the rotating shaft 10 form a “T”-shaped structure, which ensures that the outer ring 11 will not separate from the rotating shaft 10 when the outer ring 11 moves downward.

[0028] An air inlet pipe 18 is provided on one side of the outer shell 1 below the fixed plate 2, and an exhaust fan 19 is fixed on the top of the outer shell 1. The air inlet end at the bottom of the exhaust fan 19 is connected to a connecting pipe 20, and the lower end of the connecting pipe 20 passes through the top of the outer shell 1. The air outlet end at the top of the exhaust fan 19 is connected to an exhaust pipe 21. By starting the exhaust fan 19, the gas inside the outer shell 1 can be extracted, so that the interior of the outer shell 1 is in a negative pressure state, so that the external gas can enter the interior of the outer shell 1 through the air inlet pipe 18.

[0029] A handle 22 is fixed at the center of the top of the fixed tube 5 , so that the fixed tube 5 can be rotated conveniently through the handle 22 .

[0030] A pressure ring 23 is fixed to the outer side of the top of the fixed cylinder 5, and a second sealing ring 24 is fixed to the bottom of the pressure ring 23. The bottom of the second sealing ring 24 contacts the top of the outer shell 1, which increases the sealing of the connection between the outer shell 1 and the pressure ring 23 and prevents the gas inside the outer shell 1 from leaking through the connection between the outer shell 1 and the pressure ring 23.

[0031] A dust exhaust pipe 25 is provided at the bottom of the housing 1 , and a bottom cover 26 is threadedly mounted on the bottom of the dust exhaust pipe 25 , which facilitates the opening and closing of the dust exhaust pipe 25 , so that the dust collected at the bottom of the housing 1 can be discharged.

[0032] The gears 14, the rotating shaft 10 and the inner ring 12 are all distributed at equal angles with respect to the central axis of the gear ring 15. The rotating shaft 10 and the outer ring 11 are threadedly connected. The rotating shaft 10 is distributed at four equal angles with respect to the central axis of the outer ring 11, ensuring that when the gear ring 15 rotates, the gear ring 15 can drive the four gears 14 and the four rotating shafts 10 to rotate at the same time, so that the outer ring 11 can move upward or downward.

[0033] The top of the first sealing ring 4 is designed as an inverted cone structure, which is convenient for the fixed cylinder 5 and the cylindrical filter screen 6 to pass through the inside of the first sealing ring 4 from top to bottom. The inner side of the first sealing ring 4 is in contact with the outer side of the fixed cylinder 5, which increases the sealing performance of the connection between the fixed cylinder 5 and the through hole 3.

[0034] Working principle: When using the new dust removal device, first connect the air inlet pipe 18 to the external device through the pipeline. When the device is working and generates dust, start the exhaust fan 19. The exhaust fan 19 extracts the dust generated by the device into the inside of the shell 1 through the connecting pipe 20, the shell 1, the air inlet pipe 18 and the pipeline, and the dust is adsorbed on the outside of the cylindrical filter 6.

[0035] When the dust on the outside of the cylindrical filter 6 needs to be cleaned, the servo motor 16 is started, and then the servo motor 16 drives the gear 14 to rotate, and then the gear 14 drives the other three gears 14 to rotate through the gear ring 15, so that the four gears 14 and the four shafts 10 rotate at the same time. Since the shaft 10 and the outer ring 11 are threadedly connected, the outer ring 11 moves downward, and the outer ring 11 drives the four inner rings 12 and the brushes 13 inside the inner rings 12 to move downward at the same time, so that the brushes 13 can complete the dust cleaning on the outside of the four cylindrical filter screens 6 at the same time, thereby improving the cleaning efficiency of the cylindrical filter screen 6, and there is no need to disassemble the cylindrical filter screen 6 for cleaning, thereby improving the working efficiency of the dust removal equipment;

[0036] When the cylindrical filter screen 6 is damaged and needs to be repaired or replaced, the handle 22 is rotated, and the handle 22 drives the fixed cylinder 5 to rotate. Since the fixed cylinder 5 and the threaded hole 9 are threadedly connected, the fixed cylinder 5 and the cylindrical filter screen 6 move upward, thereby facilitating the removal of the cylindrical filter screen 6 for repair or replacement.

[0037] 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.
