The foam dedusting device of the embodiment is used as follows:

firstly, injecting a high-pressure solvent into the first high-pressure tank 4 and the second high-pressure tank 5 through the first liquid inlet 1 and the second liquid inlet 9, after the pressure in the first high-pressure tank 4 and the second high-pressure tank 5 is enough, pushing the first high-pressure tank 4, the second high-pressure tank 5 and the box body 33 to a working place, then opening the box door, and enabling an operator to stretch hands into the box body 33 to adjust the longitudinal elevation angle and the transverse position of the foam spray gun 21 by rotating the first handle 15 and the second handle 26 so that the foam sprayed by the foam spray gun 21 can cover the dust removal position; taking the view angle of fig. 2 as a standard, when the first handle 15 is rotated clockwise, the first handle 15 drives the first adjusting gear 14 to rotate clockwise through the first gear shaft 17, the first adjusting gear 14 rolls downward along the longitudinal rack 13, meanwhile, the first gear shaft 17 drives the fixing sleeve 35 to slide downward along the longitudinal rack 13, while one end of the first gear shaft 17 close to the curved rail 18 slides downward along the curved rail sliding groove 34, when the first handle 15 is rotated counterclockwise, the first handle 15 drives the first adjusting gear 14 to rotate counterclockwise through the first gear shaft 17, the first adjusting gear 14 rolls upward along the longitudinal rack 13, meanwhile, the first gear shaft 17 drives the fixing sleeve 35 to slide upward along the longitudinal rack 13, and one end of the first gear shaft 17 close to the curved rail 18 slides upward along the curved rail sliding groove 34; since the curved track 18 and the curved track sliding groove 34 are fixed, and the top end and the bottom end of the curved track 18 are gradually close to the longitudinal rack 13 in the embodiment, the first gear shaft 17 will gradually push the curved track 18 to the right when moving downwards or upwards, and since the top end of the fixing frame 36 is connected with the sliding block 38 through the spring 37, the bottom end of the fixing frame 36 is provided with a rotating pair (the semi-sphere 29 and the semi-sphere seat 25), the fixing frame 36 will longitudinally rotate along with the downward or upwards movement of the first gear shaft 17, thereby completing the adjustment of the longitudinal inclination angle of the foam spray gun 21; it should be noted that after the longitudinal inclination angle of the foam spray gun 21 is adjusted to a proper position, the height position of the first gear shaft 17 can be locked by tightening the pressing disk 40 to make the pressing ring on the pressing disk 40 press against the longitudinal rack, so as to prevent the first adjusting gear 14 from rolling relative to the longitudinal rack 13 under the action of the reaction force given by the fixing frame 36 through the curved rail 18 and the first gear shaft 17, and thus the height of the first gear shaft 17 is changed.

Similarly, based on the view angle of fig. 2, when the second handle 26 is rotated clockwise, the second handle 26 drives the second adjusting gear 23 to rotate clockwise through the second gear shaft 22, and since the lateral spacing between the semi-sphere 29 and the semi-sphere seat 25 is that the two cannot rotate laterally, the second adjusting gear 23 drives the lateral rack 32 (the fixed frame 36) to move horizontally to the right, and the fixed frame 36 drives the sliding block 38 to slide to the right along the guide rail 39 through the spring 37; when the second handle 26 is rotated counterclockwise, the second handle 26 drives the second adjusting gear 23 to rotate counterclockwise through the second gear shaft 22, and since the lateral limiting block 41 is disposed on the semi-sphere 29, the semi-sphere 29 and the semi-sphere seat 25 cannot rotate laterally, the second adjusting gear 23 drives the lateral rack 32 (the fixing frame 36) to move horizontally leftward, and the fixing frame 36 drives the sliding block 38 to slide leftward along the guide rail 39 through the spring 37.

After the longitudinal elevation angle and the transverse position of the foam spray gun 21 are adjusted to be in place, the first liquid outlet valve 7 and the second liquid outlet valve 6 are opened to spray foam for dust removal, and in the process of spraying foam, the first handle 15 and the second handle 26 can be continuously rotated to adjust the longitudinal elevation angle and the transverse position of the foam spray gun 21 so as to adjust the position of the sprayed foam, so that the dust removal area can be replaced.
