Description

A self-cleaning exhaust fan for textile mills

technical field

The invention belongs to the technical field of exhaust fans, in particular to a self-cleaning exhaust fan for textile factories.

Background technique

The production of the textile factory mainly includes the spinning process of cotton, wool, hemp and silk and the spinning process of polyester and nylon, and the production workshop is densely populated with machines and personnel, with large heat dissipation and dust. Because there will be a lot of dust, cloth scraps, cotton wool and other debris floating in the air in the textile workshop, these debris will follow the twitching airflow of the exhaust fan and enter the interior of the exhaust fan, which will easily block the dust filter of the exhaust fan. This will affect the air outlet effect of the exhaust fan, and even cause damage to the exhaust fan due to entering the power components of the exhaust fan, thereby causing greater losses.

When the existing exhaust fan washes the dustproof net, it is only flushed by the water flow, so it cannot quickly and efficiently clean the dust on the dustproof net, which leads to a large amount of accumulation inside the cleaned dustproof net. There is a lot of dust, and the dust is soaked in the water flow and then dried by the exhaust fan, which causes the dust to dry inside the dust filter, which is more inconvenient for subsequent cleaning, and seriously affects the air outlet effect of the exhaust fan. The problem of lint and lint floating in the air will also seriously affect the normal operation of the exhaust fan.

During operation, when the dust-proof part 4 needs to be cleaned, in the running state of the exhaust fan, the electric push rod 52 is controlled to retract, thereby driving the rotating ball 54 at the end of the swing support rod 53 to approach the annular inclined plate 55, When the rotating ball 54 contacts the annular inclined plate 55, because the rotating ball 54 rotates in the circumferential direction with the rotating shaft 63, the rotating ball 54 continuously squeezes the annular inclined plate 55 in the axial direction, thereby realizing the push and extrusion. The screen plate 57 reciprocates and squeezes the dust-proof member 4, and in the process, the water storage cavity above the dust-proof member 4 is controlled to be filled with water into the dust-proof member 4, so as to realize that the dust-proof member 4 is continuously squeezed during the water-filling process. The screen pressing plate 57 is squeezed, so that the dust adsorbed in the dust-proof member 4 is continuously taken away by the charged water flow, thereby realizing the rapid cleaning of the dust-proof member 4, and then quickly restoring the exhaust effect of the exhaust fan, and the process There is no need for manual cleaning, which saves manpower and facilitates the large-scale use and management of the textile factory; when the cleaning is completed, the electric push rod 52 is controlled to extend, so that the rotating ball 54 at the end of the swing rod 53 is separated from the ring. The shaped inclined plate 55 and the annular inclined plate 55 lose the axial pressing force, so that the dustproof member 4 is restored to the fluffy dustproof ventilation state.

During operation, the motor 36 drives the No. 1 pulley 33 to rotate through the belt 34, and then the No. 1 pulley 33 drives the exhaust fan blade 2 to rotate through the supporting shaft 31. The air is filtered to prevent the exhaust fan from accumulating dust on the exhaust fan blades 2 after long-term operation, thereby solving the problem of inconvenient cleaning of the exhaust fan blades 2. At the same time, because the surface of the exhaust fan blades 2 does not accumulate dust, the exhaust fan is improved. Effect: the exhaust fan blade 2 drives the No. 2 magnet 66 to rotate during the rotation process, the No. 2 magnet 66 drives the No. 1 magnet 65 to rotate through the action of magnetic force, and then the No. 1 magnet 65 drives the rotating shaft 63 through the connecting plate 64 to rotate, and then the rotating shaft 63 The elastic metal strip 67 is driven to rotate, and the elastic metal strip 67 can block the cotton clumps mixed in the air entering the cylinder body 12 during the rotation process, so that the cotton clumps are wrapped on the elastic metal strips 67, thereby preventing the cotton clumps from being formed. Adhering to the dust-proof parts 4, thereby preventing the cotton flock from blocking the dust-proof parts 4, thereby improving the air outlet effect of the exhaust fan, and reducing the cleaning times of the dust-proof parts 4, thereby reducing the cost of manual cleaning; During the ventilation process, the flowing airflow drives the driving fan blade 684 to rotate, and then the driving fan blade 684 drives the support shaft 681 to rotate, and then the support shaft 681 drives the elastic winding screw 685 to rotate, and then realizes the rotation of the elastic winding screw 685 through the rotating state. The cotton flocks entering the sewage storage cavity 16 are wound, thereby realizing centralized collection of the cotton flocks, and at the same time preventing the cotton flocks entering the sewage storage cavity 16 from floating out of the sewage storage cavity 16 again, thereby preventing the cotton flocks from entering the cylinder again. The dust-proof part 4 is blocked in the body 12; after the exhaust fan works for a long time, when the dust-proof part 4 needs to be cleaned, in the running state of the exhaust fan, the electric push rod 52 is controlled to retract, thereby driving the swing. The rotating ball 54 at the end of the support rod 53 is close to the annular inclined plate 55. When the rotating ball 54 contacts the annular inclined plate 55, because the rotating ball 54 rotates in the circumferential direction with the rotating shaft 63, the rotating ball 54 continuously rotates along the axis. The annular inclined plate 55 is extruded axially, so as to push the extruded mesh plate 57 to reciprocately extrude the dust-proof member 4. During the process, the water storage cavity above the dust-proof member 4 is controlled to be filled with water into the dust-proof member 4. Further, it is realized that the dust-proof part 4 is continuously squeezed by the extruding mesh plate 57 during the water filling process, so that the dust adsorbed in the dust-proof part 4 is continuously taken away by the charged water flow, thereby realizing the rapid replacement of the dust-proof part 4. 4. Cleaning is performed to quickly restore the exhaust effect of the exhaust fan, and manual cleaning is not required in the process, thereby saving manpower and facilitating the large-scale use and management of textile factories; Then, the rotating ball 54 at the end of the swing rod 53 is separated from the annular inclined plate 55, and the annular inclined plate 55 loses the axial pressing force, thereby restoring the dustproof member 4 to a fluffy dustproof and ventilated state.
