[0025] The dust collection device provided by the present utility model is particularly suitable for collecting fly ash particles. The filter chamber 1, the crushing chamber 2, the drying chamber 3 and the aggregate chamber 4 are integrated. In the filter chamber 1, the air pump 7 operates to provide power for the gas to move from the direction of the air inlet 5 to the direction of the air outlet 6. The dust removal filter bag intercepts the dust in the gas with dust. In the crushing chamber 2, the crushing knife 8 crushes the dust falling into the crushing chamber 2. In the drying chamber 3, the filtered and crushed dust is dried. The integrated design improves the degree of integration, the structure is compact and reasonable, occupies less space, the cooperation of each component is more coordinated, the operation is more stable and reliable, simplifies the operation process, reduces the operation difficulty, makes the operation simple, and is more convenient and fast to use, improves the overall work efficiency, and improves the dust collection efficiency; it should be noted here that the first filter screen 9 can be replaced according to the required particle size.

[0026] Furthermore, a second filter screen 10 is fixedly arranged at the air outlet 6 to ensure the purification of the gas discharged from the air outlet 6 and improve the environmental protection.

[0027] Further, the number of dust removal filter bags is three, namely the first filter bag 11, the second filter bag 12 and the third filter bag 13. The first filter bag 11, the second filter bag 12 and the third filter bag 13 are arranged side by side in the filter chamber 1 in sequence. The aperture of the second filter bag 12 is smaller than that of the first filter bag 11, and the aperture of the third filter bag 13 is smaller than that of the second filter bag 12. Among them, the first filter bag 11 is used to intercept larger dust particles, the second filter bag 12 is used to intercept medium-sized dust particles, and the third filter bag 13 is used to intercept the smallest dust particles. The triple filter bag filtration ensures multiple purifications of the blown-out gas, has good environmental protection performance, effectively reduces the risk of dust leakage, and reduces environmental pollution; the crushing chamber 2 is sequentially divided into the first crushing chamber 2, the second crushing chamber 2 and the third crushing chamber 2. Crushing knives 8 are provided in the first crushing chamber 2, the second crushing chamber 2 and the third crushing chamber 2. The crushing knives 8 crush the dust falling from the filter chamber 1. The first crushing chamber 2 is placed below the first filter bag 11 and can receive the dust intercepted by the first filter bag 11.
