[0002] Fly ash from municipal solid waste incineration, or simply fly ash, mainly refers to the ash collected by the flue gas purification system of municipal solid waste incineration facilities, as well as the bottom ash that settles at the bottom of the flue and chimney. It is grayish-white to dark gray in color, and the particle size is mostly <100 μm. The new type of temporary storage silo for fly ash from municipal solid waste incineration refers to a closed storage facility specifically designed for short-term storage of stabilized fly ash from municipal solid waste incineration, such as a vertical ash silo. These facilities are equipped with functions such as seepage prevention, rain protection, wind protection, sun protection, and leakage prevention, and comply with the pollution control standards for hazardous waste storage.

[0003] However, when storing fly ash in a vertical ash silo, the fly ash inside may solidify due to condensation caused by the external environment, forming ash cakes. During the discharge process, the discharge port of the equipment may be blocked by the ash cakes, resulting in discharge difficulties. Therefore, it does not meet the existing requirements. To address this, we propose a new type of temporary storage silo for fly ash from municipal solid waste incineration. Utility Model Content

[0004] The purpose of this utility model is to provide a novel temporary storage bin for fly ash from municipal solid waste incineration, in order to solve the problems mentioned in the background art, such as the fly ash inside the vertical ash bin may solidify due to condensation formed by the external environment, thus forming ash cakes, and the discharge port of the equipment may be blocked by the ash cakes during the discharge process, resulting in difficulties in discharge.

The lifting plate is circular in shape. Multiple piercing needles are fixed to the upper end face of the lifting plate, and the top end of the piercing needles pierces into the interior of the conical discharge groove through the penetrating lower end face. The metal casing is provided with a valve pipe at both the front and rear, which communicates with the interior of the conical discharge trough, and a discharge pipe is fixedly connected between the bottom ends of the two valve pipes.

[0006] Preferably, a remote control module is fixedly installed on one side of the outer surface of the stepper motor, and the stepper motor and the remote control module are electrically connected.

[0007] Preferably, a sealing structure is provided at the position where the puncture needle contacts the vertical ash silo body, and the top end of the puncture needle is tapered.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] The vertical ash silo body 1 (model 100t), stepper motor 6 (model DM542), and puncture needle 13 (model T-431) mentioned in this utility model can all be obtained from the market or through private customization.

[0016] Please see Figures 1 to 3 An embodiment of this utility model provides a novel temporary storage bin for fly ash from municipal solid waste incineration, comprising a vertical ash bin body 1, a conical discharge chute 5 located on the lower side of the interior of the vertical ash bin body 1, a metal shell 2 fixed to the lower end face of the vertical ash bin body 1 located below the conical discharge chute 5, a stepper motor 6 fixedly installed on one side inside the metal shell 2, the output shaft of the stepper motor 6 being connected to a concave rotating shaft 7 via a coupling, a concave surface 15 located at the middle position of the outer surface of the concave rotating shaft 7, a metal sleeve 8 movably fitted on the outer surface of the concave surface 15, a first rotating shaft push rod 9 connected to the upper end face of the metal sleeve 8 via a rotating shaft, a second rotating shaft push rod 10 connected to the upper end face of the first rotating shaft push rod 9 via a rotating shaft, and a guide sleeve 11 movably fitted on the upper side of the outer surface of the second rotating shaft push rod 10; The upper end face of the second rotating shaft push rod 10 is fixed with a lifting plate 12. The lifting plate 12 is circular in shape. Multiple rings of piercing needles 13 are fixed on the upper end face of the lifting plate 12, and the top end of the piercing needles 13 pierces into the interior of the conical discharge groove 5 through the penetrating lower end face. The metal casing 2 is provided with a valve pipe 3 at both the front and rear, which communicates with the interior of the conical discharge trough 5. A discharge pipe 4 is fixedly connected between the bottom ends of the two valve pipes 3. When the equipment is needed, fly ash can be directly added into the interior of the vertical ash silo body 1.

[0017] A remote control module 14 is fixedly installed on one side of the outer surface of the stepper motor 6, and the stepper motor 6 is electrically connected to the remote control module 14; the stepper motor 6 can be remotely controlled through the remote control module 14.

[0018] A sealing structure is provided at the position where the puncture needle 13 contacts the vertical ash silo body 1, and the top end of the puncture needle 13 is conical. Before the material discharge operation, the stepper motor 6 is started, and the stepper motor 6 can drive the concave rotating shaft 7 connected to it to rotate. When the concave rotating shaft 7 rotates, the metal sleeve 8, which is movably sleeved on the concave surface 15 of the outer surface of the concave rotating shaft 7, will revolve around the connection between the stepper motor 6 and the concave rotating shaft 7. As the metal sleeve 8 revolves, it will pull the lifting plate 12, which is connected to it through the first rotating shaft push rod 9 and the second rotating shaft push rod 10, to move up and down cyclically. The guide sleeve 11, which is movably sleeved on the outer surface of the second rotating shaft push rod 10, ensures that the second rotating shaft push rod 10 and the lifting plate 12 fixed on its upper end face always remain in an upright state during the up and down movement. As the lifting plate 12 moves up and down in a cycle, the multiple rings of piercing needles 13 fixed on its upper end face will also move up and down in a cycle. When there are ash cakes solidified together due to condensation inside the vertical ash silo body 1, the piercing needles 13 moving up and down in a cycle can first pierce the ash cakes and then break them up, so that they can be restored to their flow state. The above technical solution can prevent the material discharge operation of the equipment from being blocked by ash cake, thereby ensuring the smoothness of the material discharge operation.

[0019] The valve pipe 3 includes a diversion pipe and a closing valve. The closing valve is fixedly installed on the upper side inside the diversion pipe. When the stepper motor 6 is started, the closing valve inside the diversion pipe is opened. When the closing valve is opened, the fly ash inside the vertical ash silo body 1 will enter the discharge pipe 4 along the diversion pipe to perform the discharge operation.

[0020] The front end of the concave rotating shaft 7 is located inside the metal housing 2, and the concave rotating shaft 7 located inside the metal housing 2 is connected to the metal housing 2 by a roller bearing; the roller bearing structure between the concave rotating shaft 7 and the metal housing 2 can prevent the concave rotating shaft 7 from tilting during long-term rotation.

[0021] A protective cover plate is provided at the rear of the stepper motor 6 on the outer surface of the metal housing 2, and the metal housing 2 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the stepper motor 6, and when the stepper motor 6 fails, the protective cover plate can be removed to repair the stepper motor 6.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
