[0043] Embodiment 3

[0044] Reference Figures 2-3、 Figures 6-7 The difference between this embodiment and the above embodiments is that the elastic beating structure 302a includes a fixed block 302a-1 arranged on one side of the extension plate 301a-2, a fixed spring 302a-2 arranged on the upper end of the fixed block 302a-1, a beating ball 302a-3 arranged on one end of the fixed spring 302a-2, and beating blocks 302a-4 arranged on the side wall of the distribution cylinder 203 and located on both sides of the beating ball 302a-3. The fixed block 302a-1 is arranged on the side of the extension plate 301a-2 away from the center of the rotating disc 202. The fixed spring 302a-2 is vertically installed on the fixed block 302a-1.

[0045] Specifically, the pushing structure 302b includes a pushing tooth 302b-1 arranged on one side of the beating ball 302a-3, and a pushing strip 302b-2 arranged on the inner wall of the shell 101 and matched with the pushing tooth 302b-1.

The beating ball 302a-3 is deflected under the action of the pushing strip 302b-2. The fixed spring 302a-2 is twisted. When the pushing strip 302b-2 is separated from the pushing tooth 302b-1, the fixed spring 302a-2 drives the beating ball 302a-3 to shake left and right and reciprocate and contact the beating block 302a-4 under the action of the elastic force, thereby beating the distribution cylinder 203 through the beating block 302a-4, so as to shake off the fly ash attached to the inner wall of the distribution cylinder 203.

[0046] Further, the excess material recycling assembly 204 includes a scraping plate 204a arranged on the inner wall of the shell 101, a through hole 204b arranged at the central part of the rotating disc 202, and an excess material recycling pipe 204c arranged through the central part of the shell 101 and connected with the through hole 204b.

The scraping plate 204a is used to scrape off the excess fly ash on the material distributing cylinder 203, so as to ensure the quantitative feeding. Since the center of the rotating disc 202 is inwardly recessed and the upper surface of the rotating disc 202 is an inclined surface, the fly ash falling on the rotating disc 202 will slide to the central part of the rotating disc 202, and the fly ash falling on the rotating disc 202 will be concentrated and discharged through the through hole 204b. Finally, the fly ash is discharged through the excess material recycling pipe 204c.

[0047] Further, the driving assembly 201 includes a stepping motor 201a arranged at the upper end of the shell 101, and a fixing frame 201b arranged on the rotating disc 202 and connected with the output shaft of the stepping motor 201a. The fixing frame 201b is arranged outside the through hole 204b and fixedly connected with the upper surface of the rotating disc 202. The stepping motor 201a drives the fixing frame 201b to rotate, so as to drive the rotating disc 202 to rotate synchronously.

[0048] The remaining structures are the same as those of Example 2.

[0049] Operation process: When working, first, the feeding port 102 of the device is connected with a fly ash bin, and the discharging port 103 is connected with the feeding port of a receiving device. Then, the rotating disc 202 is driven to rotate by a certain angle and then stopped by the stepping motor 201a. When the rotating disc 202 rotates and drives a material distributing cylinder 203 to move below the feeding port 102, the arc-shaped plate and the extension plate 301a-2 at the bottom end of the material distributing cylinder 203 are parallel to the lower surface of the material distributing cylinder 203, and the bottom end of the material distributing cylinder 203 is sealed. At this time, the fly ash at the feeding port 102 falls into the material distributing cylinder 203. When the material distributing cylinder 203 is filled with fly ash, the rotating disc 202 is driven to rotate by the stepping motor 201a, so as to move the material distributing cylinder 203 filled with fly ash away from below the feeding port 102. At this time, the arc-shaped baffle 205 seals the feeding port 102. When the next material distributing cylinder 203 moves below the feeding port 102, the feeding port 102 is opened to continue discharging.

[0050] When the rotating disc 202 drives the distribution cylinder 203 to rotate, the distribution cylinder 203 filled with fly ash is in contact with the scraping plate 204a before moving to the arc-shaped opening, and the scraping plate 204a is used to scrape off the excess fly ash on the distribution cylinder 203, so that quantitative feeding can be ensured. Since the center of the rotating disc 202 is inwardly recessed and the upper surface of the rotating disc 202 is an inclined surface, the fly ash falling on the rotating disc 202 will slide to the central part of the rotating disc 202 and be concentrated and discharged through the through hole 204b, and finally be discharged through the excess material recovery pipe 204c;

[0051] When the distribution cylinder 203 moves to the arc-shaped opening, the arc-shaped boss 301b-3 extrudes the spherical protrusion 301b-1, the compression spring 301b-2 is extruded and shrinks, the extension plate 301a-2 drives the arc-shaped bottom plate 301a-1 to overturn around the movable shaft 301a-3, so that the bottom end of the distribution cylinder 203 is opened, and the fly ash in the distribution cylinder 203 falls into the arc-shaped opening through the opening at the bottom end of the distribution cylinder 203, and then is discharged through the discharge port 103 and fed into the receiving device. Since the amount of fly ash filled in the distribution cylinder 203 is the same each time, quantitative feeding can be ensured, and the fly ash in the receiving device can be mixed with air in a certain proportion to form a gas-ash two-phase flow, which facilitates the subsequent fly ash sorting work.

[0052] When the movable bottom plate 301a is overturned, the elastic beating structure 302a inclines together with the movable bottom plate 301a and approaches the side wall of the distribution cylinder 203. When the beating ball 302a-3 moves synchronously with the distribution cylinder 203, the actuating strip 302b-2 is in contact with the actuating tooth 302b-1, the beating ball 302a-3 is offset under the action of the actuating strip 302b-2, and the fixed spring 302a-2 is twisted. When the actuating strip 302b-2 is separated from the actuating tooth 302b-1, the fixed spring 302a-2 drives the beating ball 302a-3 to shake left and right and reciprocate and contact the beating block 302a-4 under the action of the elastic force, so that the distribution cylinder 203 can be beaten by the beating block 302a-4, thereby shaking off the fly ash adhering to the inner wall of the distribution cylinder 203 and ensuring good discharging effect.

[0053] When the distribution cylinder 203 moves out of the arc-shaped opening, the spherical protrusion 301b-1 is separated from the arc-shaped boss 301b-3, the compression spring 301b-2 pushes the extension plate 301a-2 and the arc-shaped baffle 205 to reset and block the bottom end of the distribution cylinder 203, thereby facilitating the distribution cylinder 203 to move to the below of the feeding port 102 for circulating feeding work.

[0054] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
