Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ash bunker discharging in power plants, and particularly relates to an efficient dry ash dust-proof discharging device. Background Art
[0002] The ash bunker area of the coal gangue power generation company is a key area for comprehensive dust prevention and control. Especially when discharging ash, dust flies in the air, and the ground is muddy during the rainy season, seriously affecting safe and civilized production.
[0003] Currently, in the industry, a dry ash loader is usually used to unload the dry ash in the ash bunker into a truck, and then the dry ash is transported away by the truck. A pipeline is connected between the discharge port at the bottom of the ash bunker and the feed port at the top of the dry ash loader. The dry ash in the ash bunker enters the dry ash loader along the pipeline under the action of gravity, and then falls into the truck through the discharge port of the dry ash loader.
[0004] When the truck is full, it needs to drive away from the loading and unloading position to allow the next truck to drive in. During the process of stopping ash discharging, since there is still residual dry ash in the pipeline and the dry ash loader, when the truck drives away, this dry ash will fall to the ground and be scattered everywhere by the wind, causing serious dust pollution at the production site. Therefore, it is urgent to solve the above problems. Content of the Utility Model
[0005] In order to solve the above technical problems, the utility model discloses an efficient dry ash dust-proof discharging device, which includes a feed pipe, a dry ash loader and a dust collector. The feed pipe is connected to the discharge port of the ash bunker through a pneumatic butterfly valve. The lower end of the feed pipe is connected to the feed port of the dry ash loader through a conical pipe. The dust collector is arranged on one side of the feed pipe and the dry ash loader, and is connected to the inside of the dry ash loader through a dust removal pipe.
[0006] Further, a first manual gate valve is arranged on the feed pipe above the pneumatic butterfly valve.
[0007] Further, a second manual gate valve is arranged on the feed pipe below the pneumatic butterfly valve.
[0008] Further, the discharge port at the bottom of the dust collector is connected to the inside of the dry ash loader through a screw conveyor.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] The efficient dry ash dust-proof discharging device of the utility model is connected to the dry ash loader through the dust collector. When pausing ash discharging, the pneumatic butterfly valve is closed and the dust collector is opened. Through the negative pressure action of the dust collector, the residual dry ash in the feed pipe, the conical pipe and the dry ash loader is transported into the dust collector through the dust removal pipe for subsequent recycling, so as to avoid the residual dry ash directly falling to the ground or being scattered into the air, and improving the on-site production environment and air quality.

[0020] Such asFigure 1-2 As shown in the figure, the high-efficiency dry ash dust-proof discharging equipment in this embodiment includes a feed pipe 1, a dry ash loader 2, and a dust collector 3. The feed pipe 1 is connected to the discharge port of the ash silo 5 through a pneumatic butterfly valve 4. The pneumatic butterfly valve 4 can control the opening and closing of the ash discharge of the ash silo 5 and adjust the ash discharge flow rate. The lower end of the feed pipe 1 is connected to the feed port of the dry ash loader 2 through a conical pipe 6. Among them, both the dust collector 3 and the ash silo 5 are erected on a steel structure platform. The dust collector 3 is arranged on one side of the feed pipe 1 and the dry ash loader 2, and the discharge port at the bottom of the dry ash loader 2 is at a certain height from the ground, which is convenient for a truck to park under the dry ash loader 2 for ash discharge; the discharge port at the bottom of the dry ash loader 2 is telescopic and can adapt to various types of vehicles.
[0021] The suction port of the dust collector 3 is connected to the inside of the dry ash loader 2 through a dust removal pipe 7, and the discharge port at the bottom of the dust collector 3 is connected to the inside of the dry ash loader 2 through a screw conveyor 8; among them, the dust collector 3 can adopt a bag dust collector commonly used in the field.
[0022] A first manual gate valve 9 is provided on the upper side of the pneumatic butterfly valve 4 on the feed pipe 1, and a second manual gate valve 10 is provided on the lower side of the pneumatic butterfly valve 4. During the ash discharge process, both the first manual gate valve 9 and the second manual gate valve 10 are in the normally open state. The first manual gate valve 9 and the second manual gate valve 10 serve as emergency switches to provide double protection. When the pneumatic butterfly valve 4 fails, the first manual gate valve 9 and / or the second manual gate valve 10 can be manually closed to prevent dry ash leakage.
[0023] After the ash discharge is completed, first close the pneumatic butterfly valve 4 and turn on the dust collector 3. Through the negative pressure effect of the dust collector 3, the residual dry ash in the feed pipe 1, the conical pipe 6, and the dry ash loader 2 is transported into the dust collector 3 through the dust removal pipe 7 for subsequent recycling.
[0024] After the dust collector 3 has worked for a period of time, the residual dry ash in the feed pipe 1, the conical pipe 6, and the dry ash loader 2 has been completely absorbed. At this time, turn off the dust collector 3, and the truck can drive away from the ash discharge station, thus avoiding the residual dry ash from directly falling to the ground or floating into the air, improving the on-site production environment and air quality.
[0025] After the dry ash recovered by the dust collector 3 accumulates to a certain amount, it can be transported back into the dry ash loader 2 through the screw conveyor 8 for loading, effectively avoiding the waste of dry ash and improving the ash discharge efficiency.
