[0002] Waste incineration power generation is a technology that processes urban domestic waste and converts it into electrical energy. The core of this technology is to use domestic waste as fuel through high-temperature thermochemical reactions and burn it in an incinerator under strictly controlled conditions.

[0003] The existing ash conveying device for waste incineration power generation forms an air duct in the ash conveying cylinder through the operation of the Roots blower. The residual ash falls from the bottom of the boiler into the ash hopper and then into the ash conveying cylinder. Due to the effect of negative pressure, the residual ash in the ash hopper is sucked into the ash conveying cylinder to assist in the conveying of the residual ash. However, in actual use, the residual ash may be blocked between the ash hopper and the ash conveying cylinder, which may affect the subsequent ash conveying process. Utility Model Content

[0004] In view of this, the utility model aims to provide an ash conveying device for waste incineration power generation, which can continuously push the residual ash in the ash hopper into the ash conveying cylinder and efficiently break up and stir the residual ash, thereby effectively preventing the residual ash from being blocked and assisting the transportation of the residual ash.

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0021] like Figure 1 , 2 As shown in , 4, it includes a base frame 101, and the four corners of the lower surface of the base frame 101 are respectively provided with supporting legs 102, and the upper end of the base frame 101 is slidably provided with a support frame 103, and the right side of the upper surface of the support frame 103 is provided with an ash conveying cylinder 104, and the right side of the ash conveying cylinder 104 is provided with an ash conveying pipe 105, and the left side of the upper surface of the support frame 103 is provided with a Roots blower 106, and the air outlet pipe of the Roots blower 106 is connected with the ash conveying pipe 105, and the installation openings symmetrically opened on the outer arc surface of the ash conveying cylinder 104 are respectively provided with ash hoppers 108, and an ash conveying auxiliary module for auxiliary ash conveying can also be provided between the ash conveying pipe 105 and the ash hopper 108.

[0022] like Figure 1 , 2 As shown in FIG. 4 , hydraulic telescopic columns 107 are provided on both sides of the left and right sides of the base frame 101 , and the telescopic ends of the hydraulic telescopic columns 107 are fixed to the lower surface of the support frame 103 by bolt connection.

[0023] like Figure 2 ,3 As shown in 4, the ash conveying auxiliary module includes two installation plates 201 that are welded and fixed inside the ash conveying cylinder 104 and are symmetrically distributed on the left and right. A spline cylinder 202 is rotatably arranged inside the installation plate 201, and a driving blade 203 is arranged at the lower end of the spline cylinder 202. A support plate 204 is arranged at the upper end of the interior of the ash hopper 108. A movable rod 205 is slidably arranged between the support plate 204 and the vertically adjacent spline cylinder 202. A plurality of vertically evenly distributed ash conveying plates 206 are arranged at the lower end of the outer arc surface of the movable rod 205. A scattering unit for scattering the residual ash is also arranged between the movable rod 205 and the ash hopper 108. The spline cylinder 202 is also provided with a driving unit for driving the spline cylinder 202 to rotate; the scattering unit includes a scattering paddle 207 fixed to the upper end of the outer arc surface of the movable rod 205, and a plurality of evenly distributed adjusting rods 209 are arranged on the upper side of the outer arc surface of the movable rod 205. An adjusting ring 210 is arranged on the upper side of the inner part of the ash hopper 108. The adjusting rods 209 are respectively installed in cooperation with adjacent adjusting rings 210, and the outer arc surfaces of the adjusting rods 209 are provided with scattering plates 211; the driving unit includes a driving blade 203 arranged at the bottom end of the spline cylinder 202, and the driving blades 203 are installed in cooperation with the Roots blower 106.

[0024] like Figure 1 , 2 As shown in FIG. 4 , a control panel 301 is disposed on the front side of the support frame 103 , and the Roots blower 106 and the hydraulic telescopic column 107 are both electrically connected to the control panel 301 .

After the residual ash is broken up by the dispersing paddle 207 and the dispersing plate 211, the residual ash is driven downward by the ash conveying plate 206, so that the residual ash can enter the ash conveying cylinder 104 quickly and efficiently, thereby realizing the rapid ash conveying of the residual ash; during the rotation of the movable rod 205, through the cooperation between the adjusting rod 209 and the adjusting ring 210, the movable rod 205 is driven to rotate and move up and down continuously, thereby continuously pushing the residual ash in the ash hopper 108 into the ash conveying cylinder 104, thereby efficiently breaking up and stirring the residual ash, effectively preventing the residual ash from being blocked and assisting the transportation of the residual ash.

[0027] According to another embodiment of the present invention, Figure 1 , 2 As shown in FIG. 3 , the top of the movable rod 205 is provided with a material pushing paddle 208. In the process of conveying the residual ash, the movable rod 205 drives the material pushing paddle 208 at the top thereof to rotate and move up and down, which can assist the unloading of the boiler.
