Preferably, the filter device 5 employs a filter bag or a filter cartridge. The filtering device 5 adopts a small-diameter design, so that enough filtering devices 5 can be arranged in the accommodating space to increase the filtering area in unit volume. Through the setting to 5 minor diameters of filter equipment, can reduce the volume of accommodation space when guaranteeing filter area, and then can make portable dust removal car of unloading miniaturized.

In one embodiment, the filter bag is made of a film-coated polyester needle felt which is subjected to waterproof, oil drainage and surface calendering treatment. The material of the filter cylinder is polyester fiber. The diameter of the filter bag or cartridge is preferably 90 mm to 330 mm.

As shown in fig. 1, the dust suction device 3 is connected to the box 2, and more specifically, the dust suction device 3 is partially disposed outside the box 2 and partially disposed inside the box 2, and is communicated with each filter 5 in the accommodating space. In the operation process of the movable discharging dust removal vehicle, the dust suction device 3 can pump out air in the accommodating space, so that negative pressure is formed in the accommodating space, and then dust-containing gas generated when the discharging vehicle discharges materials enters the accommodating space under the action of the negative pressure.

In an embodiment, the dust suction device 3 includes an air outlet unit 31 and an air inlet unit 32, and the air outlet unit 31 is communicated with the plurality of filtering devices 5 and is used for extracting air in the accommodating space so as to form negative pressure in the accommodating space. The air inlet unit 32 is communicated with the accommodating space, so that the external dust-containing gas enters the accommodating space through the air inlet unit 32 under the action of negative pressure.

In an embodiment, as shown in fig. 1, the air outlet unit 31 includes an induced draft fan 311, an air outlet 312 and an air duct, and the air inlet unit 32 is an air inlet and is communicated with the accommodating space.
