[0002] The ash silo system consists of the ash silo body, silo top equipment, exhaust system, material level indicator, ash silo gasification system, and unloading system.
[0003] For a long time, due to the changes in the fineness of pulverized coal in the boiler, the fineness of ash particles has changed. This has caused the dust collected by the dust extraction fan to have poor flowability in the bottom ash hopper, resulting in poor ash discharge or blockage. The dust extraction fan has lost its function of reducing dust, and the ash silo cannot discharge ash normally. It often takes maintenance personnel several hours to clear the blockage, which seriously affects the normal production order of the ash silo and has a significant impact on the safety of the ash silo material level and the surrounding environment.

[0021] like Figures 1 to 4 As shown, this utility model provides a technical solution: a dust suppression device during ash unloading from an ash silo, comprising a mounting frame 1, a dust removal component 4, and a blower component 5. An ash receiving tank 2 is mounted on the mounting frame 1. The top of the ash receiving tank 2 is connected to the rear outlet of the ash silo, and a control valve 6 is installed at the bottom of the ash receiving tank 2. The control valve 6 discharges the ash from the ash receiving tank 2. An air pump 3 is mounted on the upper outer wall of the ash receiving tank 2. The air inlet of the air pump 3 is connected to the ash receiving tank 2, and the air outlet of the air pump 3 is connected to the upper end of the dust removal component 4 via a pipe. When ash blocks fall into the ash receiving tank 2, the air pump 3 generates suction, drawing the ash blocks into the receiving tank. The dust generated during the process in tank 2 is adsorbed by the air intake, thus preventing the dust from spreading into the air. That is, with the cooperation of the air pump 3 and the dust removal component 4, the dust in the ash tank 2 is adsorbed and purified. The dust removal component 4 is equipped with a blower component 5, a part of which extends into the dust removal component 4, and the remaining part of which is installed on the outer wall of the dust removal component 4. Under the action of the blower component 5, a directional airflow is formed in the dust removal component 4. This realizes that the dust discharged into the dust removal component 4 by the air pump 3 forms a directional airflow in the dust removal component 4, which accelerates the collection of dust, improves dust removal efficiency, and reduces the impact of dust on the environment.
[0022] In a further embodiment, the dust removal assembly 4 includes a support frame 41 located on the side of the mounting frame 1. A collection tank 42 is mounted on the support frame 41. The outlet of the air pump 3 is connected to the collection tank 42, meaning that the air pump 3 transports the dust generated in the dust collection tank 2 to the collection tank 42 through a pipe connected to the outlet of the air pump 3. The collection tank 42 collects the generated dust, reducing its impact on the environment. An mounting plate 43 is installed inside the collection tank 42. Figure 3 As shown, the mounting plate 43 is installed horizontally at the upper end of the collection tank 42. The mounting plate 43 has several mounting holes, and pulse filter bags 44 are installed in the mounting holes. That is, the dust discharged into the collection tank 42 by the air pump 3 is concentrated and collected in the pulse filter bags 44 with the cooperation of the mounting holes and the pulse filter bags 44. Furthermore, a solenoid valve 45 is also installed at the lower end of the collection tank 42. The solenoid valve 45 is used to control the dust collected in the collection tank 42 to be discharged from the collection tank 42.
[0023] In a further embodiment, the blower assembly 5 includes an upper air compression tank 51, such as... Figure 3 As shown, the upper air compressor tank 51 is mounted on the outer wall of the dust removal assembly 4 via a mounting bracket. The air inlet of the upper air compressor tank 51 is connected to an external device via a valve, and compressed air is filled into the upper air compressor tank 51 using the external device. The upper air compressor tank 51 has several air outlet pipes 52, which are arranged in a linear array on the upper air compressor tank 51. The air outlet end of each air outlet pipe 52 is connected to an exhaust pipe 53, which is perpendicularly connected to the air outlet pipe 52. The exhaust pipe 53 is inserted into the dust removal assembly 4. Inside the dust assembly 4, after the exhaust pipe 53 extends into the collection tank 42, it is located above the mounting plate 43. The exhaust pipe 53 has several exhaust holes along its length. The exhaust holes are located above the pulse bag 44. With the cooperation of the upper air compressor tank 51, the exhaust pipe 53, and the exhaust holes, directional air is blown into the pulse bag 44, which can create a directional airflow inside the pulse bag 44. The dust discharged into the collection tank 42 by the air pump 3 can quickly flow into the pulse bag 44, realizing the rapid collection of dust.
[0024] In a further embodiment, a fluidizing component 7 is further installed at the lower end of the dust removal assembly, wherein the fluidizing component 7 includes a lower air compression tank 71, such as... Figure 3 As shown, the lower air compressor tank 71 is installed at the lower end of the outer wall of the dust removal component. The lower air compressor tank 71 is connected to an external device through an air inlet pipe. Compressed air is filled into the lower air compressor tank 71 by the external device. Several horizontal pipes 72 are installed in a horizontal linear array on the upper side of the lower air compressor tank 71. The horizontal pipes 72 are located at the lower end of the collection tank. Several air outlets 73 are opened near the lower end of the collection tank on the horizontal pipes 72. That is, with the cooperation of the lower air compressor tank 71, the horizontal pipes 72 and the air outlets 73, directional air is blown into the inner wall of the lower end of the collection tank, which can quickly remove the dust remaining on the inner wall of the lower end of the collection tank.
