[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , the utility model provides a technical solution: a multi-stage filtering and recycling device for woodworking dust, comprising a recycling body 1, which is used for filtering and recycling dust entering the interior thereof;

[0028] A fixed bracket 2 is fixed to the bottom of the recycling body 1 and is used to support the entire recycling body 1;

[0029] A suction port 3 is provided on the outside of the recovery body 1 and is used for the introduction of dust;

[0030] A dust outlet 4 is provided at the bottom of the recovery body 1 and is used to discharge the collected dust;

[0031] A gas outlet 5 is provided at the top of the recovery body 1 and is used to discharge the filtered gas;

[0032] Also includes;

[0033] The middle partition 7 is arranged at both sides of the inside of the recycling body 1, and a dust bag 8 is arranged in the middle thereof for filtering and removing dust;

[0034] The bottom of the middle partition 7 and the recovery body 1 penetrate each other, and mesh holes are evenly distributed at the corresponding positions of the middle partition 7 and the suction port 3 for the entry of small particles of gas;

[0035] The present application provides a multi-stage filtering and recovery device for woodworking dust with an intermediate partition 7. Specifically, when in use, the dust is sucked to the position of the suction port 3 through an external pump body, and then reaches the gap between the intermediate partition 7 and the recovery body 1. The large volume of wood chips will be filtered by the intermediate partition 7 and fall to the bottom of the recovery body 1, while the small particles of dust will reach the position of the dust removal bag 8. After that, the small particles of dust will be filtered again by the dust removal bag 8. Finally, the filtered dust is discharged at the position of the dust outlet 4, and the filtered gas is discharged at the position of the gas outlet 5.

[0036] Among them, according to Figure 2-3 As shown, the recovery device further includes a moving mechanism 6, which is arranged between the middle partition 7 and the recovery body 1, and is used to dredge the large volume of dust particles accumulated therein;

[0037] Specifically, when large particles of gas are filtered and located between the middle partition 7 and the recovery body 1, the driving moving mechanism 6 can also be used to move it between the middle partition 7 and the recovery body 1, so as to achieve the effect of clearing and dropping the large volume of particle dust accumulated inside.

[0038] Furthermore, according to Figure 2-5 As shown, the moving mechanism 6 includes a driving mechanism and a dredging mechanism, and the driving mechanism is used to drive the dredging mechanism above it to move.

[0039] The driving mechanism includes a driving motor 61 and a screw rod 62. The driving motor 61 is bolted on the outer wall surface of the recovery body 1, and its top end is coaxially connected to the screw rod 62, and the screw rod 62 is arranged in the middle gap between the middle partition 7 and the recovery body 1.

[0040] The dredging mechanism includes a movable sleeve 63, a connecting rod 64 and a wire brush 65. The movable sleeve 63 is arranged outside the screw rod 62 and is threadedly connected to the screw rod 62.

[0041] A connecting rod 64 is integrally mounted on the bottom of the movable sleeve 63, and wire brushes 65 are evenly distributed on the inner side of the connecting rod 64;

[0042] The outer wall of the middle partition 7 is connected to the top of the wire brush 65

[0043] Among them, when the moving mechanism 6 is started, it is necessary to start the driving motor 61 so that it drives the screw rod 62 at its top to rotate, thereby making it threadedly connected with the moving sleeve 63, driving the connecting rod 64 at the bottom of the moving sleeve 63 to move between the middle partition 7 and the recovery body 1, thereby completing the dredging effect. Since a wire brush 65 is also provided on the outside of the connecting rod 64, it can dredge the external mesh of the middle partition 7 to ensure that no blockage occurs.
