[0026] As a preferred embodiment, the structure between the dust collector outer box 1 and the dust collection hopper 3 of this utility model is solid and firm, which facilitates the entry of dust-laden gas into the dust filter inner cylinder 2. After multiple filtrations and purifications, clean air is delivered to the dust collector outer box 1 and then discharged outward through the first air pump 15 and the air outlet pipe 16, while the filtered dust enters the dust collection hopper 3.

[0027] In this embodiment, the second air pump 21 is covered with a sealing sleeve 22, which is made of silicone rubber. A primary filter screen 24 is provided at the lower end of the upper fixing sleeve 23, and an intermediate filter screen 25 is installed in the middle of the dust filter inner cylinder 2. The primary filter screen 24 and the intermediate filter screen 25 are arranged parallel to each other vertically.

[0028] As a preferred embodiment, the sealing sleeve 22 in this utility model is fitted over the second air pump 21 to achieve a safe sealing effect, so that the dust-laden gas drawn in can be processed from top to bottom through the primary filter screen 24 and the intermediate filter screen 25, which is faster and more convenient.

The clean gas can be transported to the dust collector outer box 1 through the left vent pipe 27 and the filter element 26, and the air left after purification can be lowered into the dust collection hopper 3 through the ash pipe 20 for convenient centralized collection.

[0031] This invention effectively solves the problems of existing dust removal devices not being able to cleanly remove dust-laden air, having low filtration efficiency, and being inconvenient and impractical. This invention facilitates the rapid extraction of dust-laden gas from the working environment of excavators and drilling rigs, enabling rapid multi-stage filtration and purification. It helps to output clean gas separately, while the dust left after filtration and purification is collected and treated centrally, making it safer, cleaner, more efficient, and practical.

[0032] The above embodiments are used to explain and illustrate the present utility model, and not to limit the utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims should be included within the protection scope of the present utility model.
