DETAILED DESCRIPTION

[0020] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

At the same time, the dust conveying pipe 1, the connecting pipe 10 and the air intake pipe 9 suck the dust into the solid box 2. The air is then discharged through filtering measures, and the dust is separated inside the solid box 2. It falls by gravity and accumulates inside the hopper 7. Then, the collected dust is transported to the ash storage bin for storage through the discharge pipe 8 and the scraper.

[0023] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 ; The solid box 2 is provided with a separation assembly 3 inside, and the separation assembly 3 includes a filter plate 31. The width of the filter plate 31 is the same as the inner width of the solid box 2, and the two sides of the filter plate 31 are arc-shaped to avoid the problem of being stuck due to rotation. At the same time, the filter holes of the filter plate 31 are convenient for air flow. The outer surface of the filter plate 31 is rotatably connected to the inside of the solid box 2. The filter plates 31 are arranged at equal distances inside the solid box 2 along the air flow direction. The filter plates 31 are arranged at equal distances with multiple filter ranges that can be increased to increase the amount of dust collected. The multiple filter plates 31 are arranged along the The axis of rotation is set at an equal angle, that is, the difference in angle between two adjacent filter plates 31 is the same, and 360° is an integer multiple of this difference. This integer value is the number of filter plates 31 set. At the same time, the angle value of a single rotation of the filter plate 31 is the same as the difference, which can ensure that both ends of the filter plate 31 are in contact with both sides of the inner wall of the solid box 2 in real time to ensure real-time filtration of dust. The outer surface of the filter plate 31 is fixedly connected to a rotating shaft 32, and one end of the rotating shaft 32 is rotatably connected to the body of the solid box 2 and extends to the solid box 2.

[0024] In this embodiment, when the dust enters the solid box 2 through the air inlet pipe 9, the dust is ionized by the electrolytic column 38 and carries a negative charge. When passing near the filter plate 31, the conductive plate 37 makes the filter plate 31 and the patch 310 carry a positive charge, so that the dust is adsorbed on the surface of the patch 310. At the same time, a larger volume of dust falls directly into the hopper 7 by gravity and accumulates. When the dust adsorption amount increases, the electrostatic generator increases the output power to improve the adsorption performance of the patch 310. At the same time, through the transmission connection of the transmission belt 35 and the transmission wheel 34, multiple rotating shafts 32 drive the corresponding filter plates 31 to rotate synchronously, which is convenient for the flow of air on the one hand, and can perform double-sided adsorption of dust on the other hand.

[0026] In this embodiment, the air with filtered dust is pumped by the fan 6 and discharged through the exhaust pipe 4, the muffler and the chimney, and the air contacts the paddle 337 when flowing inside the exhaust pipe 4, thereby pushing the paddle 337 to move, so that the transmission rod 335 drives the worm 333 to rotate synchronously, and through the engagement of the worm 333 and the worm wheel 332, as well as the engagement of the transmission gears 334 on both sides, the vertical rod 331 drives one side of the rotating shaft 32 to rotate, so that the filter plate 31 obtains power by recovering the kinetic energy of the air during the dust removal process, which can reduce the air flow rate and reduce noise on the one hand, and realize the recycling of energy on the other hand.

The arc cloth 51 is made of the same material as the patch 310, and its filtering gap is slightly larger than the patch 310, so as to filter the escaping dust that is not adsorbed by the patch 310 but fails to fall by its own weight. The arc cloth 51 is arranged on the outside of one end of the exhaust pipe 4, and arc strips 52 are fixedly connected to both sides of the outer surface of the arc cloth 51, and both sides of the arc strips 52 are fixedly connected to the inner wall of the solid box 2, and the sum of the widths of the arc strips 52 and the arc cloth 51 on both sides is the same as the inner width of the solid box 2, and the outer surfaces of the arc strips 52 on both sides are fixedly connected to the inside of the solid box 2, and a push rod 53 is movably connected between the outer surfaces of the two arc strips 52, and the length of the push rod 53 is the same as the width of the arc cloth 51, and the outer surface of the push rod 53 is consistent with the outer surface of the arc cloth 51.

At the same time, when the missing gear 57 and the rotating gear 56 are disengaged, the rotating rod 55 is reversed due to the gravity of the push rod 53, and the push rod 53 pushes the arc cloth 51 in the opposite direction. This can be repeated to perform real-time anti-blocking treatment of the arc cloth 51.
