The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] The following describes an embodiment of the utility model based on its overall structure.

[0022] Example

[0023] Please refer to the attached Figure 1 , 2 As shown in Figures 4 and 5, in a preferred embodiment of the utility model, a dust suppression device for a slag bin includes a slag bin 10, a feed port 11 is embedded in the top of the slag bin 10, a support frame 12 is provided on the outer wall of the slag bin 10, a dust shield plate 13 is fixedly connected to the bottom of the slag bin 10, a discharge port 14 is embedded in the bottom of the slag bin 10, and a dust suppression device 20 is provided on the outer wall of the discharge port 14.

[0024] It should be noted that, in the present embodiment, when the waste slag in the slag bin 10 needs to be transported out, the waste slag is discharged from the discharge port 14 .

[0025] Please refer to the attached Figure 1 , 2As shown in Figures 3 and 4, in a preferred embodiment of the utility model, the dust suppression device 20 includes a water storage tank 21 arranged on the outer wall of the discharge port 14, the outer wall of the water storage tank 21 is provided with an opening and closing component 22, the inner wall of the water storage tank 21 is provided with a spraying component 23, the bottom of the dust shield 13 is provided with a dust suction pipe 24, the top of the dust suction pipe 24 is provided with a water supply pipe 25, the bottom of the dust suction pipe 24 is provided with a dust suction component 26, the execution end of the opening and closing component 22 is provided with a water supply component 27, the opening and closing component 22 includes two first solenoid valves 221 symmetrically arranged on the outer wall of the water storage tank 21, the execution ends of the two first solenoid valves 221 are connected to the water inlet of the water storage tank 21, the spraying component 23 includes a water outlet pipe 231 arranged at the water outlet of the water storage tank 21, the water outlet pipe 231 is provided with a plurality of one-way valves 232, and the execution ends of the plurality of one-way valves 232 are provided with an atomizing Nozzle, the dust suction component 26 includes a dust inlet pipe 261 arranged at the bottom of the dust suction pipe 24, one end of the dust inlet pipe 261 is provided with a dust suction pump 262, one end of the dust suction pump 262 is connected to the dust storage bin 263 through a pipe, the water supply component 27 includes two multi-outlet water pumps 271 symmetrically arranged at the execution end of the first solenoid valve 221, one end of the two multi-outlet water pumps 271 is provided with a water pipe 272, the water pipe 272 passes through the side wall of the dust baffle 13 and is connected to the tap water source, the execution end of the multi-outlet water pump 271 is provided with a water supply component 273, the multi-outlet water pump 271 has two water outlets, the water supply component 273 includes a second solenoid valve 2731 arranged at the water outlet of the two multi-outlet water pumps 271, the execution end of the second solenoid valve 2731 is provided with a water pipe 2732, one end of the water pipe 2732 is connected to the water inlet of the water supply pipe 25.

[0026] It should be noted that, in the present embodiment, while the waste residue is discharged, the first solenoid valve 221 is opened. When the first solenoid valve 221 is opened, the second solenoid valve 2731 is closed, and the multi-outlet water pump 271 draws the water in the water pipe 272 from the first solenoid valve 221 into the water outlet pipe 231, and then sprays the water into a mist from the spray head of the one-way valve 232, so as to suppress the waste residue. When the waste residue is discharged, floating dust will also be generated when it collides with the carrying vehicle. At this time, the staff starts the dust suction pump 262 to draw the floating dust from the dust suction pipe 24 into the dust inlet pipe 261, and then draws it into the dust storage bin 263. Because one-time dust suppression can greatly reduce the floating dust, and the remaining floating dust is very little, the dust storage bin 2 63 can fully carry the remaining floating dust, and the dust shield 13 can also simply limit the movement trajectory of the floating dust, so that the floating dust can be better removed by the dust collection component 26. When the waste residue is removed, the second solenoid valve 2731 works, and the first solenoid valve 221 stops working. The multi-outlet water pump 271 enters the second solenoid valve 2731 from another water outlet, and then enters the water supply pipe 25 from the water pipe 2732. The water supply pipe 25 sends water into the dust collection pipe 24 to perform a simple flushing of the dust collection pipe 24 to prevent too much dust from accumulating at the dust collection port of the dust collection pipe 24, resulting in a poor dust collection effect. After flushing, all devices are turned off and wait for the next dust suppression work.

[0027] The working principle of the utility model is:

[0028] When the waste slag in the slag bin 10 needs to be transported out, the waste slag is discharged from the discharge port 14. While the waste slag is being discharged, the first solenoid valve 221 is opened. When the first solenoid valve 221 is opened, the second solenoid valve 2731 is closed, and the multi-outlet water pump 271 draws the water in the water pipe 272 from the first solenoid valve 221 into the water outlet pipe 231, and then sprays the water into a mist from the spray head of the one-way valve 232 to suppress dust on the waste slag. When the waste slag is discharged, floating dust will also be generated when it collides with the carrying vehicle. At this time, the staff starts the dust suction pump 262 to draw the floating dust from the dust suction pipe 24 into the dust inlet pipe 261, and then draws it into the dust storage bin 263. Because one-time dust suppression can greatly reduce floating dust, the remaining floating dust Very little, so the dust storage bin 263 can fully carry the remaining floating dust, the dust shield 13 can also simply limit the movement trajectory of the floating dust, so that the floating dust can be better removed by the dust collection component 26, when the waste residue is removed, the second solenoid valve 2731 works, at this time the first solenoid valve 221 stops working, the multi-outlet water pump 271 enters the second solenoid valve 2731 from another water outlet, and then enters the water supply pipe 25 from the water pipe 2732, the water supply pipe 25 sends water into the dust collection pipe 24 to perform a simple flushing of the dust collection pipe 24 to prevent too much dust from accumulating at the dust collection port of the dust collection pipe 24, resulting in poor dust collection effect, after flushing, turn off all devices and wait for the next dust suppression work.
