Description

Technical Field

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

[0002] Cement is a very commonly used building material. Powdered cement is mixed with water to form a slurry, which can harden in the air or in water and is widely used in civil engineering, water conservancy, national defense and other projects.

Therefore, it is necessary to remove cement dust in the air.

[0003] The existing dust removal device only removes dust through the filter screen, which has low dust removal efficiency and limited dust removal effect. The cement dust collected when filtering dust through the filter screen is easy to be clogged, thereby affecting the dust removal effect and causing incomplete dust removal of the air.

[0023] The side of the box 1 is connected to the U-shaped push rod, and the bottom of the box 1 is connected to four symmetrical self-locking universal wheels by bolts. The box 1 can be easily moved by the push rod and the universal wheel, which enhances the applicability in actual use. The support frame 2 is respectively located on both sides of the dust removal tube 3. The inside of the dust removal tube 3 is rotatably connected to the output end of the motor 5 through a sealed bearing, and the side of the dust removal tube 3 is rotatably connected to one end of the rotating shaft 6 through a sealed bearing. In this way, the rotating shaft 6 and the filter plate 7 can be driven by the motor 5 to rotate. While the filter plate 7 is used for filtering, its own rotation can cooperate with the brush plate 8 to clean and scrape the dust on the side of the filter plate 7, so as to avoid the situation where cement dust blocks the filter plate 7. The outer side of the air inlet pipe 4 is provided with a thread, and the air inlet pipe 4 is threadedly connected to the threaded pipe 16 through a thread. The air inlet pipe 4 and the air outlet pipe 11 are respectively located at the two ends of the dust removal tube 3, and one end of the air outlet pipe 11 extends to the inside of the box 1 and is connected to the output end of the air pump 12. The air is made to enter the dust collecting cylinder 3 from the dust collecting hood 17 through the air pump 12, and then enter the filter screen 13 from the air outlet pipe 11 for secondary filtration after being filtered by the filter plate 7, and then discharged from the exhaust hole 15. The filter plate 7 is circular, and there are two filter plates 7. The filter plate 7 is located above the integrated bucket 9, and the side of the filter plate 7 abuts against the brush plate 8. The integrated bucket 9 is located at the bottom of the dust collecting cylinder 3, and the integrated bucket 9 is tilted downward from the edge to the center. The integrated bucket 9 is connected to the discharge pipe 10, and one end of the discharge pipe 10 is tilted downward. The dust collected in the integrated bucket 9 can be discharged and collected by opening the sealing cover at one end of the discharge pipe 10, which effectively reduces the difficulty of collection by the staff.

The filter screen 13 is located above the exhaust hole 15, and the exhaust holes 15 are evenly distributed in a linear array on the side of the box body 1. The exhaust hole 15 can prevent the discharged gas from blowing to the bottom surface so that the dust flies up and spreads into the air.

[0024] Working principle: When in use, the staff moves the entire device into the production workshop, and then manually turns the handwheel 18 to rotate the threaded tube 16, so that the threaded tube 16 moves up and down on the outside of the air inlet pipe 4, and further adjusts the height of the dust hood 17, and then starts the air pump 12 through the controller 19 to allow air to enter the inside of the box body 1 from the dust hood 17, and then enter the filter screen 13 from the air outlet pipe 11. In this process, the dust removal effect is achieved through the double filtration of the filter plate 7 and the filter screen 13, and then the air is discharged from the exhaust hole 15, and the motor 5 is started by the controller to make the rotating shaft 6 and the filter plate 7 rotate synchronously. When the filter plate 7 rotates, the brush plate 8 is used to clean and scrape off the cement dust on the side of the filter plate 7, and then the dust falls into the integrated bucket 9 for collection. When the integrated bucket 9 needs to be cleaned, the sealing cover at one end of the discharge pipe 10 is opened, and the dust inside the integrated bucket 9 is discharged from the discharge pipe 10 for recovery, and the filter screen 13 can be replaced by opening the sealing door 14.
