Description

Technical Field

[0001] The utility model belongs to the technical field of graphite dust removal equipment, in particular to a rapid dust removal device for graphite production. Background Art

[0002] During graphite processing, graphite is typically crushed into a powder for subsequent reassembly into various components. This crushing process generates a large amount of fine graphite dust. This dust not only pollutes the work environment but can also harm the respiratory system of operators. Bag filters are commonly used to intercept dust particles in the air, thereby purifying the air and achieving dust removal. However, bag filters accumulate dust over time, affecting their filtering effectiveness. They are also limited in their ability to filter extremely fine particles, and the bags require regular cleaning with vibration, which can easily cause dust contamination. Utility Model Content

[0035] like Figure 1-5 As shown, a rapid dust removal device for graphite production includes a dust removal box 1, and the upper and lower ends of the side surfaces of the dust removal box 1 are respectively connected to an air inlet pipe 11 and an air outlet pipe 12;

[0036] A driving mechanism 4 is provided on the top of the dust removal box 1;

[0037] A dust removal mechanism 2 and a dust removal mechanism 3 are provided in the dust removal box 1;

[0038] The spray dust reduction mechanism 2 includes a water tray 21, which is connected to the driving mechanism 2 and rotates in the dust removal box 1 under the drive of the driving mechanism 2.

[0039] The dust removal mechanism 3 includes a ventilation hood 31, which opens downward and is located at the lower part of the dust removal box 1. A fan 32 is provided at the opening of the ventilation hood 31, and the fan 32 is connected to the driving mechanism 4 via a first rotating shaft 33. A liquid tank 35 is fixed to the bottom of the dust removal box 1. The liquid tank 35 includes a liquid layer 351 below and an air layer 352 above. A ventilation pipe 34 is connected to the upper end of the side of the ventilation hood 31. The other end of the ventilation pipe 34 extends into the liquid layer 351 of the liquid tank 35, and the air layer 352 is connected to the outlet pipe 12.

[0040] A drain pipe 13 is provided at the bottom of the dust removal box 1 .

[0041] The dust-laden gas enters the dust removal box 1 through the air inlet pipe 11, the driving mechanism 4 drives the water tray 21 to rotate, and the atomizing nozzle 22 sprays liquid during the rotation to fully spray and reduce dust on the gas in the dust removal box 1. The liquid with dust gathers at the bottom of the dust removal box 1, and the driving mechanism 4 drives the fan 32 to rotate. The gas passing through the spraying dust reduction mechanism 2 is sucked into the ventilation hood 31 and enters the liquid tank 35 from the ventilation pipe 34. After the gas enters the liquid layer 351, the residual particles will remain in the liquid layer 351, and the gas after complete dust reduction is discharged from the gas layer 352 through the air outlet pipe 12 to complete the dust removal of the gas.

[0042] Preferably, the bottom of the dust removal box 1 is hemispherical, so that the liquid carrying dust can be collected and discharged from the drain pipe 13.

[0043] Preferably, a pressure valve 14 is provided on the drain pipe 13 , and when the liquid in the dust removal box 1 accumulates enough and generates sufficient pressure, it will be discharged through the pressure valve 14 .

[0044] Preferably, the driving mechanism 4 includes a connecting cover 41, which is fixedly connected to the top of the dust removal box 1, and a motor 42 is fixed in the connecting cover 41, and the output end of the motor 42 is connected to the first rotating shaft 33;

A driven gear 44 is rotatably provided inside the connecting cover 41, and a driving gear 45 is fixedly provided on the first rotating shaft 33. The driving gear 45 is meshed and connected with the driven gear 44, and the driven gear 44 is meshed and connected with the inner gear ring 43.

[0046] The motor 42 rotates to drive the fan 32 and the driving gear 45 to rotate. The driving gear 45 drives the driven gear 44 to rotate. The driven gear 44 drives the inner gear ring 43 to rotate, and then the water tray 21 rotates to spray the gas in the dust removal box 1 to reduce dust.

[0047] Preferably, the number of gears of the driving gear 45 is less than the number of gears of the driven gear 44, and the number of gears of the inner ring 43 is more than the number of gears of the driven gear 44. By setting the number of gears of the driving gear 45, the driven gear 44 and the inner ring 43, the rotation speed of the inner ring 43 can be reduced and the spraying quality of the atomizing nozzle 22 can be improved.

The first partition plate 37 is provided in the liquid layer 351 and is located below the outlet of the ventilation pipe 34. The first partition plate 37 is inclined. If the gas entering the liquid layer 351 contains dust, the dust falls into the first partition plate 37 and slides to the bottom of the liquid tank 35 as the first partition plate 37 tilts down, thereby isolating the dust from the outlet of the ventilation pipe 34, and preventing the liquid layer 351 from becoming turbid due to the continuous blowing of dust at the bottom by the entry of gas.

[0050] Preferably, a second partition plate 38 is provided in the liquid tank 35. The second partition plate 38 is provided in the liquid layer 351 and is located above the outlet of the ventilation pipe 34. The second partition plate 38 is arranged at an angle. By setting the second partition plate 38, the passage path of the gas in the liquid is improved, the dust reduction effect is improved, and the second partition plate 38 also plays a role in blocking the dust particles on the first partition plate 37 that have not yet fallen to the bottom of the liquid tank 1.

[0051] The working principle of the utility model is as follows: the gas containing dust enters the dust removal box 1 through the air inlet pipe 11, the motor 42 rotates to drive the driving gear 45 to rotate, the driving gear 45 drives the driven gear 44 to rotate, the driven gear 44 drives the inner gear ring 43 to rotate, and then the water tray 21 rotates to spray the gas in the dust removal box 1 to reduce dust, and the liquid containing dust gathers at the bottom of the dust removal box 1. The motor 42 drives the fan 32 to rotate, and the gas passing through the spray dust reduction mechanism 2 is sucked into the ventilation cover 31 and is discharged from the ventilation pipe. 34 enters the liquid box 35, and the residual particles after the gas enters the liquid layer 351 will remain in the liquid layer 351. The dust falls into the first partition plate 37 and slides to the bottom of the liquid box 35 as the first partition plate 37 tilts and lowers, thereby isolating the dust from the outlet of the ventilation pipe 34, preventing the liquid layer 351 from continuously blowing the dust at the bottom due to the entry of gas and causing turbidity. The gas blocked by the second partition plate 38 is discharged from the gas layer 352 through the outlet pipe 12 to the dust removal box 1, completing the dust removal of the gas.
