[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a dust-proof fly ash recovery device, including a shell 1, a connecting pipe 1 2, a connecting pipe 2 3, a hose 4, a block 5, a magnetic ring 6, a motor 7, a baffle 1 8, a baffle 2 9, a discharge plate 10, a rotating wheel 11, a sieve plate 12, a spring 13, and an eccentric wheel 14.

[0031] This device has the effect of preventing dust, specifically:

[0032] The outer shell 1 is a box body connected to a bucket shape at the bottom, and the upper and lower surfaces of the outer shell 1 are respectively provided with connection structures, and the connection structure is provided with a telescopic hose 4 to facilitate the connection between the device and the fly ash generation and collection structure, thereby reducing the contact between the fly ash and the air. The connection structure includes a connecting pipe 1 2, and a connecting pipe 2 3 is provided on one side of the connecting pipe 1 2. The connecting pipe 1 2 and the connecting pipe 2 3 are connected through a hose 4, and the hose 4 is a telescopic structure. A clamping block 5 is provided in an annular shape on the side surface of the connecting pipe 1 2, and the clamping block 5 is spherical, and the clamping block 5 is fixedly connected to the surface of the connecting pipe 1 2 through a connecting rod, and a clamping groove is provided on the surface of the connecting pipe 2 3 accordingly. The connecting pipe 2 3 is provided through the upper surface of the outer shell 1, and the lower surface of the outer shell 1 is symmetrically provided with the same connecting pipe 1 2 and connecting pipe 2 3;

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, hold the connecting pipe 2 and pull it upward, and the block 5 on the lower surface of the connecting pipe 2 is separated from the groove on the surface of the connecting pipe 2 3. At this time, the connecting pipe 2 above the shell 1 can be connected to the bottom of the ash hopper that produces fly ash. Since the connecting pipe 2 and the connecting pipe 2 3 are connected by a hose 4, the hose 4 will not interfere with the movement of the connecting pipe 2. Similarly, the connecting pipe 2 below the shell 1 is connected to the fly ash storage device, so that the fly ash is kept in the relatively closed shell 1 during the recovery process to avoid dust caused by contact between the fly ash and the air.

[0034] This device has the effect of recovering magnetic materials, specifically:

[0035] A magnetic separation structure is arranged inside the shell 1, and a magnetic ring 6 is arranged in the magnetic separation structure to separate and collect magnetic substances in the fly ash. The magnetic separation structure includes a magnetic ring 6, which is rotatably mounted on the inner wall of the shell 1, and a rotating shaft is arranged inside the magnetic ring 6 to penetrate the surface of the shell 1. A motor 7 is fixedly mounted on the rear surface of the shell 1, and the output end of the motor 7 is connected to the rotating shaft of the magnetic ring 6. Baffles 1 8 and baffles 2 9 are symmetrically arranged on both sides of the magnetic ring 6, and the other sides of the baffles 1 8 and baffles 2 9 are fixedly mounted on the inner wall of the shell 1, and the baffles 1 8 and baffles 2 9 are arranged obliquely. Baffle plate 1 8 is in contact with the surface of the magnetic ring 6, baffle plate 2 9 is provided with a gap with the surface of the magnetic ring 6, a rotating wheel 11 is provided on one side of the magnetic ring 6, both ends of the rotating wheel 11 are rotatably connected to the inner wall of the shell 1, a plurality of scrapers are provided in an annular shape on the outer surface of the rotating wheel 11 to contact the surface of the magnetic ring 6, a discharge plate 10 is provided below the rotating wheel 11, the discharge plate 10 is fixedly connected to the inner wall of the shell 1, the discharge plate 10 is a sloped structure, the upper end of the sloped discharge plate 10 is aligned with the lower end of the magnetic ring 6, and a discharge port is provided on the side surface of the shell 1 to be aligned with the end of the discharge plate 10;

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, after the fly ash falls from the upper connecting pipe 2 3 into the outer shell 1, the motor 7 is started, and the motor 7 drives the magnetic ring 6 to rotate. At this time, the fly ash falls to the surface of the magnetic ring 6 under the action of the baffle 1 8 and the baffle 2 9, and the non-magnetic material in the fly ash falls from the gap between the magnetic ring 6 and the baffle 2 9, and falls to the surface of the screen plate 12 below. The magnetic material in the fly ash is adsorbed by the magnetic ring 6. As the magnetic ring 6 rotates, when the magnetic material contacts the scraper on the surface of the runner 11, under the action of the scraper, the magnetic material falls to the surface of the discharge plate 10 below, and is discharged from the outer shell 1 along the sloped discharge plate 10 to be collected.

[0037] This device has the effect of vibration screening, specifically:

[0038] A screening structure is arranged inside the shell 1, and a vibrating screen plate 12 is arranged in the screening structure to sort the non-magnetic substances in the fly ash. The screening structure includes a screen plate 12, which is arranged obliquely on the inner wall of the shell 1, and one end of the screen plate 12 is slidably connected to the inner wall of the shell 1, an eccentric wheel 14 is arranged on the lower surface of the screen plate 12, and the other end of the eccentric wheel 14 is fixedly installed on the inner wall of the shell 1, and two eccentric wheels 14 are symmetrically arranged above the screen plate 12, and the two eccentric wheels 14 are connected to the same rotating shaft surface, and the rotating shaft of the eccentric wheel 14 passes through the surface of the shell 1, and a transmission belt is arranged at the output end of the motor 7 to be connected to the rotating shaft of the eccentric wheel 14;

[0039] like Figure 1 , Figure 3 and Figure 4As shown, after the fly ash falls from above onto the surface of the sieve plate 12, the non-magnetic substances in the fly ash, such as unburned coal blocks, are intercepted by the sieve plate 12 and discharged from the outer casing 1 along the inclined sieve plate 12 for collection. The remaining fly ash passes through the sieve plate 12 and is collected by the connecting pipe 2 3 and the connecting pipe 1 2 below. When the sieve plate 12 is screening, the motor 7 drives the eccentric wheel 14 to rotate, and the rotating eccentric wheel 14 pushes the sieve plate 12 downward, and the sieve plate 12 compresses the spring 13 downward. When the sieve plate 12 loses the driving force of the eccentric wheel 14, the sieve plate 12 rebounds under the action of the spring 13, causing the sieve plate 12 to vibrate up and down, which is convenient for screening the fly ash.

[0040] Working principle: When using the anti-dust fly ash recovery device, the outer shell 1 can be connected to the fly ash generation and collection structure by using the connecting pipe 1 2 and the connecting pipe 2 3 on the upper and lower surfaces of the outer shell 1 to prevent the fly ash from being exposed to the air and generating dust during the recovery process. The motor 7 is started, and the motor 7 drives the magnetic ring 6 to rotate. The fly ash falls onto the surface of the magnetic ring 6. The magnetic material is adsorbed by the magnetic ring 6 and rotates with the magnetic ring 6. Under the action of the rotating wheel 11, it falls to the discharge plate 10 below and is collected. The rotation of the motor 7 will also drive the eccentric wheel 14 to rotate. The eccentric wheel 14 and the spring 13 can drive the screen plate 12 to vibrate up and down, thereby increasing the screening efficiency, screening the non-magnetic material in the fly ash, and increasing the overall practicality.
