For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0024] The following is combined with Figure 1-4 The utility model is further described.

[0025] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a dry ash bulk dust removal device for an ash bin in a thermal power plant.

[0026] The specific technical solution includes an ash bin body 1 and an ash absorbing component 3;

[0027] like Figure 1-4As shown, a connecting hole 2 is provided above the ash bin body 1, and the connecting hole 2 can facilitate the communication between the dust collecting hood 303 and the recovery pipe 305; the dust absorption component 3 is installed inside the ash bin body 1, and the dust absorption component 3 is used to prevent dust from flying when the dry ash is loaded. The dust absorption component 3 includes a recovery bin 301 installed in the ash bin body 1, a fixed plate 302 fixedly installed in the connecting hole 2, and a dust collecting hood 303 fixedly installed in the ash bin body 1 and located below the connecting hole 2. The recovery bin 301 can conveniently collect the absorbed dry ash, and the fixed plate 302 can connect the connecting hole 2 and the recovery pipe The gap between the connecting hole 2 and the recovery pipe 305 is sealed to prevent dust from entering the equipment layer on the ash bin body 1 through the gap between the connecting hole 2 and the recovery pipe 305. The dust collecting hood 303 can collect air conveniently. A pump body 304 is fixedly installed below the recovery bin 301. The pump body 304 can drive the air flow inside the recovery pipe 305. The side wall of the pump body 304 is fixedly equipped with a recovery pipe 305 that passes through the connecting hole 2 and the fixed plate 302. The recovery pipe 305 can drive the air flow inside the dust collecting hood 303. The recovery pipe 305 is passed through the top of the dust collecting hood 303.

[0028] When the transport vehicle drives into the preset position inside the ash bin body 1, the dust hood 303 is located above the ash loading port of the transport vehicle, and dry ash is transported to the transport vehicle through the bulk loader 401. At the same time, the pump body 304 is started to drive the air flow inside the recovery pipe 305, and the recovery pipe 305 drives the air flow inside the dust hood 303 through the connecting hole 2. The airflow inside the dust hood 303 enters the recovery pipe 305 through the connecting hole 2. The dry ash raised inside the ash loading port of the transport vehicle is located inside the channel below the ash bin body 1, and can enter the recovery pipe 305 through the connecting hole 2 along with the airflow below the dust hood 303. The dry ash inside the recovery pipe 305 enters the recovery bin 301 through the pump body 304, and can absorb the raised dry ash.

[0029] like Figure 1-3 As shown, an anti-overflow component 4 is installed in the ash bin body 1, which is used to prevent dry ash from entering the equipment layer in the ash bin body 1 during ash loading. The ash bin body 1 is provided with an ash discharge port 5 located on one side of the connecting hole 2, and the ash discharge port 5 can facilitate the transportation of dry ash to the transport vehicle. The anti-overflow component 4 includes a bulk loader 401 fixedly installed in the ash bin body 1 and a dust cover 402 and a telescopic tube 403 located on the upper and lower sides of the ash discharge port 5. The bulk loader 401 can facilitate the transportation of dry ash to the dust cover 402, and the dust cover 402 can be covered on the ash discharge port 5 to prevent the raised dry ash from entering the equipment layer on the ash bin body 1 from the inside of the ash discharge port 5. The telescopic tube 403 can facilitate more accurate ash discharge for the transport vehicle. The dust cover 402 is fixedly installed in the ash bin body 1, and the telescopic tube 403 is fixedly installed in the ash bin body 1 and is passed through the dust collecting hood 303.

[0030] When the ash loading port on the transport vehicle is located below the telescopic tube 403, the bulk loader 401 is started to transport dry ash to the ash discharge port 5. The dust cover 402 can be covered above the ash discharge port 5 to prevent dry ash from overflowing from the ash discharge port 5. The dry ash inside the ash discharge port 5 enters the telescopic tube 403, and the dry ash inside the telescopic tube 403 falls into the ash loading port of the transport vehicle, so that the dry ash can be loaded inside the transport vehicle. When dry ash is raised from the ash loading port, the dust cover 402 can prevent the dry ash from being raised upward from the ash discharge port 5 and entering the equipment layer on the ash bin body 1.

[0031] like Figure 1-2 As shown, a ventilation pipe 6 is fixedly installed on the side wall of the recovery bin 301 , and the ventilation pipe 6 can conveniently connect the recovery bin 301 and the filter box 7 .

[0032] like Figure 1-2 As shown, a filter box 7 is fixedly installed at one end of the ventilation pipe 6 away from the recovery bin 301. The filter box 7 can filter the dry ash floating inside the recovery bin 301 and prevent the dry ash inside the recovery bin 301 from overflowing.

[0033] like Figure 1-2 As shown, an air outlet pipe 8 is fixedly installed on the side wall of the filter box 7 away from the ventilation pipe 6. The air outlet pipe 8 can facilitate the discharge of gas inside the recovery bin 301. When the pump body 304 transports dry ash to the inside of the recovery bin 301, the gas inside the recovery bin 301 is squeezed and discharged through the ventilation pipe 6, the filter box 7 and the air outlet pipe 8, which is beneficial to the stability of the internal pressure of the recovery bin 301.

[0034] like Figure 2 As shown, a bracket 9 fixedly connected to the ash bin body 1 is fixedly installed below the recovery bin 301 , and the bracket 9 can support the bottom of the recovery bin 301 .
