[0027] As Figure 1 and Figure 2 shown, the present application provides a cement material conveying device, including a support frame 1. A conveying assembly 2 for conveying cement material is provided on the support frame 1. A dust-proof box 3 is provided at the feeding end of the conveying assembly 2. The dust-proof box 3 is fixedly arranged on the support frame 1. An inlet 4 is provided at the upper end of the dust-proof box 3. A dust collection assembly 5 is connected to one side of the dust-proof box 3. A chute pipe 6 is provided between the bottom of the dust-proof box 3 and the conveying assembly 2. The chute pipe 6 is communicated with the dust-proof box 3. The chute pipe 6 is inclined. During use, it is connected to the outlet of the fly ash bin through the inlet 4. When fly ash enters the dust-proof box 3, dust will be generated. The dust collection assembly 5 collects the dust generated in the dust-proof box 3. The fly ash in the dust-proof box 3 falls to the conveying assembly 2 through the chute pipe 6, and the conveying assembly 2 conveys the fly ash. The chute pipe 6 can reduce the falling height of the fly ash, reduce the flying of dust, reduce the health hazards to operators, reduce environmental pollution, and at the same time eliminate the hidden danger of dust explosion.
[0028] As Figure 1 and Figure 2 shown, the dust collection assembly 5 includes a dust collection pipe 51, a dust collection fan 52, and a dust collection box 53. The dust collection box 53 is fixedly arranged on the support frame 1. The dust collection box 53 is connected to the dust-proof box 3 through the dust collection pipe 51. The dust collection fan 52 is arranged on the dust collection pipe 51. Specifically, the dust collection fan 52 sucks the dust in the dust-proof cover into the dust collection box 53 through the dust collection pipe 51.
[0029] As Figure 2 and Figure 3 shown, a water pipe 7 and a plurality of atomizing nozzles 8 are arranged in the dust collection box 53. The water pipe 7 is fixedly arranged in the dust collection box 53. The plurality of atomizing nozzles 8 are evenly arranged on the water pipe 7. One end of the water pipe 7 extends outside the dust collection box 53. Connect the water pipe 7 to the external water pipe network. Water enters the water pipe 7, and the atomizing nozzles 8 spray water mist to combine with the dust in the dust collection box 53, so that the dust condenses into large particles and falls to the bottom in the dust collection box 53.
[0030] As Figure 2As shown, a dust exhaust pipe 9 is connected to the bottom of the dust collecting box 53 , and a dust exhaust valve 10 is provided on the dust exhaust pipe 9 . When the dust exhaust valve 10 is opened, dust at the bottom of the dust collecting box 53 is discharged through the dust exhaust pipe 9 .
[0031] like Figure 2 and Figure 3 As shown, an exhaust port 11 is provided at the top of the dust collecting box 53, a first filter screen 12 is fixedly provided at the exhaust port 11, an activated carbon layer 13 is laid on the top of the first filter screen 12, a second filter screen 14 is placed on the top of the activated carbon layer 13, a counterweight block 15 is fixedly provided on the top of the second filter screen 14, after the dust in the dust collecting box 53 combines with the water mist, most of it falls to the bottom of the dust collecting box 53 and is separated from the airflow, the exhaust port 11 can discharge the airflow in the dust collecting box 53 to maintain the internal air pressure of the dust collecting box 53 stable, wherein the first filter screen 13 is provided on the top of the first filter screen 12, and the second filter screen 14 is provided on the top of the second filter screen 14. The net 12, the activated carbon layer 13, and the second filter net 14 can filter the airflow to prevent dust in the airflow from being discharged from the exhaust port 11 and polluting the environment. The counterweight block 15 presses the second filter net 14 onto the activated carbon layer 13. When the activated carbon layer 13 needs to be replaced, the counterweight block 15 is lifted upwards, the second filter net 14 is taken out, and then the activated carbon layer 13 is taken out and refilled with a new activated carbon layer. Then the second filter net 14 is put back into the exhaust port 11 to press the new activated carbon layer. The replacement method is simple and convenient.
[0032] like Figure 1 and Figure 2 As shown, the conveying assembly 2 includes an active roller 21, a driven roller 22, a conveyor belt 23 and a conveying motor 24. The active roller 21 and the driven roller 22 are both rotatably arranged on the support frame 1. The conveying motor 24 is fixed on the support frame 1. One end of the active roller 21 is connected to the output shaft of the conveying motor 24. The active roller 21 and the driven roller 22 are connected through the conveyor belt 23. Specifically, the conveying motor 24 drives the active shaft to rotate, and the conveyor belt 23 rotates with the cooperation of the driven shaft, so as to transport the fly ash falling from the chute 6 onto the conveyor belt 23.
[0033] like Figure 1 and Figure 2 As shown, the inclination angle of the chute 6 is 10° to 30°. Specifically, the larger the inclination angle of the chute 6, the steeper the chute 6, the faster the fly ash falls, but it is also more likely to cause secondary dust. In this embodiment, the inclination angle of the chute 6 is 15°, the chute 6 is relatively flat, and the secondary dust can be effectively avoided. The inclination angle of the chute 6 refers to the angle between the chute 6 and the horizontal plane of the conveyor belt 23.
[0034] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
