[0006] As a further improvement to the above solution, the distribution pipes are arranged on the outer wall of the discharge pipe at intervals along the axial direction, and the distribution pipes are evenly distributed on the outer wall of the discharge pipe in the circumferential direction, so that the angle between the distribution pipes and the discharge pipe is 45-30 degrees;
[0007] This is to facilitate the even distribution and evacuation of fly ash into the ash bin, ensure that the top surface of the fly ash in the ash bin is as flat as possible, avoid tilting of the top surface of the fly ash, and ensure safe storage of the ash bin.
[0008] As a further improvement to the above solution, a cover plate is rotatably provided on the outer end of the material distribution pipe;
[0009] The cover plate is used to prevent a small amount of fly ash from falling from the distribution pipe and forming dust.
[0010] As a further improvement to the above solution, the lower port of the seat tube matches the notch provided on the fabric tube;
[0011] The seat tube is clamped on the material distributing tube through the slot, so that the hopper and the seat tube are restricted to prevent the hopper from rotating on the upper end of the material distributing tube.
[0012] As a further improvement to the above solution, a pipe seat is slidably mounted on the slag discharge pipe, and bolts are connected to the pipe seat. The slag discharge pipe is supported by the pipe seat, and the hopper is further supported to enhance the carrying capacity of the hopper.
[0013] Compared with the existing technology, the utility model has the following advantages: simple structure, reasonable design, novel and unique idea, fly ash is fed into the hopper, large particles of fly coal that are formed into small clusters are filtered out through the pyramid filter screen, and the powdered and granular fly ash leaks out and falls into the discharge pipe, and is then discharged into the ash bin through the distribution pipe; the fly ash is fed into the hopper, and the load is supported by the spring under the total weight of the hopper and the fly ash contained therein. After the fly ash leaks out, the hopper rebounds under the action of the spring to generate vibration, which helps the filtering and screening effect of the pyramid filter screen, and the large particles of small clusters screened out roll onto the arc screen plate and fall into the ash bin from the slag discharge pipe, so that the small clusters of fly ash are evenly distributed in the ash bin, and at the same time, the fly ash is evenly distributed through the distribution pipe, so that the top of the fly ash in the ash bin is flat, avoiding an inclined layer.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figures 1 to 4 As shown in the figure, a coarse ash storage feeding device includes a base 1, a discharge pipe 2 is vertically arranged on the base 1, a plurality of distribution pipes 3 are arranged through the side wall of the discharge pipe 2, the upper end of the discharge pipe 2 is fitted with a seat pipe 4, the upper end of the seat pipe 4 is connected to the hopper 5, a pyramidal filter screen 61 is arranged in the hopper 5, the lower edge of the pyramidal filter screen 61 is horizontally connected to the arc filter screen 62, a slag discharge pipe 7 is arranged through the arc filter screen 62, the lower end of the hopper 5 is connected to a support ring 9, the support ring 9 is provided with a spring 10, and the lower end of the spring 10 presses the upper end of the discharge pipe 2.
[0020] As a further improvement to the above solution, the distribution pipes 3 are arranged on the outer wall of the discharge pipe 2 at intervals along the axial direction, and the distribution pipes 3 are evenly distributed on the outer wall of the discharge pipe 2 in the circumferential direction, so the angle between the distribution pipes 3 and the discharge pipe 2 is 35°;
[0021] This is to facilitate the even distribution and evacuation of fly ash into the ash bin, ensure that the top surface of the fly ash in the ash bin is as flat as possible, avoid tilting of the top surface of the fly ash, and ensure safe storage of the ash bin.

The powdered and granular fly ash leaks down into the discharge pipe 2 and is then discharged into the ash bin through the distribution pipe 3; the fly ash is fed into the hopper 5, and the load is supported by the spring 10 under the total weight of the hopper 5 and the fly ash it contains. After the fly ash leaks down, the hopper 5 rebounds under the action of the spring 10 to generate vibration, which helps the filtering and screening effect of the pyramid-shaped filter screen 61, and the large particles of small clusters screened out roll onto the arc-shaped screen plate and fall into the ash bin from the slag discharge pipe 7, so that the small clusters of fly ash are evenly distributed in the ash bin.
