The hopper frame is connected and installed on the surface of the sleeve, and the inner wall of the sleeve is in sliding contact with the outer edge of the outer end of the cross-shaped long plate on the sub-filter element. The middle of the cross-shaped long plate forms four exhaust chambers through a central pipe, and each exhaust chamber is communicated with the space between two adjacent plate bodies on the cross-shaped long plate through an arc-shaped hole. A filter plate is installed in the arc-shaped hole. The circular plates at both ends of the cross-shaped long plate are respectively rotatably connected to the inner ports of both ends of the sleeve through bearings.

[0022] Please refer to Figures 1-3 As shown, a biomass wood chip dust storage bin includes a bin body 1, a discharge pump 2, a motor 4, and a wood chip dust filtering mechanism located in a wood chip filter box 3. The wood chip dust filtering mechanism includes a hopper frame 31, a sleeve 32, strip-shaped discharge holes 33, a sub-filter element 34, a filter plate 35, a short pipe 36, a circular plate 37, and an exhaust pipe 38. The hopper frame 31 is communicatively installed on the surface of the sleeve 32, and the inner wall of the sleeve 32 is in sliding contact with the outer edge of the outer end of a cross-shaped long plate 341 on the sub-filter element 34. The middle of the cross-shaped long plate 341 forms four exhaust chambers 344 through a central pipe 342, and each exhaust chamber 344 is communicatively connected to the space between two adjacent plates on the cross-shaped long plate 341 through an arc-shaped hole 343. A filter plate 35 is installed in the arc-shaped hole 343. Circular plates 37 at both end faces of the cross-shaped long plate 341 are respectively rotatably connected to the two ends of the sleeve 32 through bearings. The middle of one circular plate 37 is connected to the shaft end of the motor 4, and four exhaust pipes 38 are distributed at the other circular plate 37, and each exhaust pipe 38 is communicatively connected to the inside of a corresponding exhaust chamber 344.

[0023] Furthermore, a wood chip dust vacuum cleaner connection pipe 5 is communicatively installed on the surface of the hopper frame 31.

[0024] Furthermore, the hole specification at the connection between the hopper frame 31 and the sleeve 32 is much smaller than the specification of the arc-shaped hole 343.

[0025] Furthermore, the exhaust pipe 38 is located in the short pipe 36, and one end face of the short pipe 36 is fixedly connected to the other circular plate 37.

[0027] Furthermore, the bottom of the wood chip filter box 3 is communicated with the inside of the bin body 1, and a discharge pump is provided at the bottom of the bin body 1.

[0028] When the present utility model is in use, under the action of an external vacuum cleaner, wood chip dust enters the corresponding partition space in the sleeve 32 through the wood chip dust vacuum cleaner connecting pipe 5 and the hopper frame 31. Each partition space is composed of a part of the sleeve 32, two adjacent plate bodies on the cross-shaped long plate 341, and a part of the central pipe 342. The flowing wood chip dust is first filtered by the filter plate 35 and then enters the exhaust chamber 344 and is discharged through the exhaust pipe 38. When a large amount of wood chip dust adheres to each partition space, the motor 4 drives the sub-filter element 34 connected by the circular plate 37 to rotate, so that each partition space rotates and is inverted in the bin body 1, facilitating the falling and collection of the wood chip dust in the bin;

[0029] Compared with the prior art, four partition spaces formed by the sleeve, the cross-shaped long plate, and the central pipe, and at the same time, filter plates are provided at the communication parts between each partition space and the exhaust chamber, with four filtering structures. Moreover, the filtered air flow is discharged to the outside of the bin through the exhaust pipe, avoiding the influence of the air flow on the inside of the bin. By driving the connected cross-shaped long plate and central pipe with the motor, each partition space rotates and is inverted in the bin body, facilitating the falling and collection of the wood chip dust in the bin, realizing the function of filtering wood chip dust in an orderly manner. And the wood chip dust falls into the bin under the action of gravity, which is beneficial to cleaning the filtering and containing space.
