AI Technical Summary
Dust easily floats during the unloading process of existing boiler ash discharge hoppers, threatening workers' health and affecting the efficiency of the shielding curtain. Dust easily adheres to the single protective structure after long-term use, resulting in a decrease in shielding and cooling efficiency.
A dust-blocking mechanism and a dust-suppressing mechanism are installed on the boiler ash discharge hopper. The dust-blocking mechanism uses an electric cylinder to drive the pad support to lift and cover the unloading trolley. The dust-suppressing mechanism uses a spray pipe to atomize liquid to form micron-level water mist, which collides and condenses with the dust, causing the dust to settle.
It effectively controls dust dispersion, improves shielding effect and cooling efficiency, protects worker health, and reduces dust pollution.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figures 1 to 5 As shown, a boiler ash discharge hopper with a dust suppression structure includes a hopper body 1, an electric cylinder 3, and a support 4. A discharge through hole 8 is provided through the outer side of the hopper body 1. The electric cylinder 3 is installed on the outer side of the hopper body 1. A dust blocking mechanism 6 is provided on the outer side of the hopper body 1. The dust blocking mechanism 6 covers the area below the hopper body 1 and the unloading trolley to prevent dust from overflowing during the unloading process and causing dust pollution. A dust suppression mechanism 9 is provided on the outer side of the support 4. The dust suppression mechanism 9 atomizes the liquid to form a large number of micron-sized water mist particles that float in the air and can continuously collide, condense, and settle with the dust.
[0023] In this embodiment, the dust-blocking mechanism 6 includes a guide rail 2, an electric cylinder 3, a pad support 4, an isolation soft pad 5, a guide groove 7, and a slider 10. The guide rail 2 is symmetrically arranged on the outside of the funnel body 1. The slider 10 is connected to the outside of the guide rail 2. The slider 10 is symmetrically arranged on the outside of the pad support 4. The slider 10 is connected to the inside of the guide rail 2 and the guide groove 7 respectively. The guide groove 7 is symmetrically opened on the outside of the funnel body 1. The top of the isolation soft pad 5 is connected directly below the pad support 4. The output end of the electric cylinder 3 is connected to the top of the slider 10.
[0024] In this embodiment, the electric cylinder 3 is connected to the outside of the pad bracket 4 via a slider 10 connected to its output end. The slider 10 guides the pad bracket 4 to prevent it from tilting.
[0025] In this embodiment, the dust suppression mechanism 9 includes a transverse support plate 11, pipe clamps 12, a spray pipe 13, a micro water pump 14, and a second isolation pad 15. The transverse support plate 11 is symmetrically installed on the outside of the pad support 4. Pipe clamps 12 are evenly spaced at the bottom end of the transverse support plate 11. The output end of the spray pipe 13 is connected to the micro water pump 14. The second isolation pad 15 is provided directly above the transverse support plate 11. One side of the second isolation pad 15 is connected to the outside of the pad support 4. The second isolation pad 15 shields the pad support 4 to prevent dust from escaping from the gaps.
[0026] In this embodiment, the pad bracket 4 is connected to the top of multiple sets of pipe clamps 12 through symmetrically distributed transverse support plates 11. The pipe clamps 12 are used to position the spray pipe 13, which facilitates the quick disassembly and assembly of the spray pipe 13.
[0027] In this embodiment, the transverse support plate 11 is connected to the "L"-shaped spray pipe 13 through pipe clamps 12 arranged at equal intervals. The spray pipe 13 is used to treat the dust in the boiler and reduce the heat of the dust.
[0028] In practical applications, this type of boiler ash discharge hopper with a dust suppression structure includes the following tasks:
[0029] Step 1: The operator first installs the slider 10 on the outside of the pad bracket 4 and connects it to the outside of the guide rail 2 and the guide groove 7. Then, the corresponding size isolation soft pad 1 5 is installed directly below the pad bracket 4, so that the top of the pad bracket 4 is connected to the isolation soft pad 2 15, thereby blocking the gap between the pad bracket 4 and the funnel body 1 and preventing dust from escaping from the gap between the isolation soft pad 2 15 and the funnel body 1.
[0030] Step 2: The operator can open the electric cylinder 3 and use the electric cylinder 3 to drive the pad support 4 to move vertically. The pad support 4 slides on the outside of the guide rail 2 through the slider 10 set on the outside. The isolation soft pad 5 covers the unloading trolley to prevent the dust discharged from the boiler from spreading everywhere. The funnel body 1 is used to discharge the coal blocks after combustion in the boiler and discharge them directly into the unloading trolley through the discharge hole 8 set at the bottom.
[0031] Step 3: The operator connects the pipe clamp 12 to the outside of the spray pipe 13, and connects the spray pipe 13 to the input end of the micro water pump 14. When the pad bracket 4 slides on the outside of the guide rail 2 through the slider 10 set on the outside, it drives multiple sets of horizontal support plates 11 and spray pipe 13 to descend vertically, thereby synchronously adjusting the height of the spray pipe 13.
[0032] Step 4: Use micro water pump 14 to inject liquid into the interior of spray pipe 13. Spray pipe 13 performs dust suppression treatment on the discharged debris and cools down the residual heat in the boiler. Spray pipe 13 forms a large number of micron-sized water mist particles that float in the air and can continuously collide, condense and settle with the dust. After unloading is completed, use electric cylinder 3 to drive pad support 4 and isolation soft pad 5 to rise vertically, so that the unloading trolley can be moved out from under the funnel body 1.
[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
