[0002] Coal-fired power generation is a method of producing electricity using coal as the main fuel. It generates heat energy by burning coal and then converts it into electrical energy. The coal adding device for coal-fired power generation is a mechanical device used to improve coal combustion efficiency and reduce resource waste. The device usually drives the transmission column through a drive motor to drive the crushing knife to cut and crush the coal in the adding barrel.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the utility model describes a coal adding device for coal-fired power generation, comprising a shell 1, a rotating shaft 2, and a support rod 3. A support plate 14 is installed on one side of the inner wall of the shell 1, and a filter plate 15 distributed in a circular array is embedded and installed inside the support plate 14.

A gear box 22 is provided on the outer wall of the lower end of the rotating shaft 2, and an output shaft 23 is provided on one side of the outer wall of the lower end of the gear box 22. A connecting plate 24 is installed on the outer wall of the lower end of the output shaft 23, and support rods 3 equidistantly distributed in parallel are installed on the outer wall of the upper end of the connecting plate 24. A sleeve 31 is provided on the outer wall of the support rod 3, and a piston body 32 is installed on the outer wall of the upper end of the support rod 3.

[0031] When in use, the gear box 22 is installed on the lower end of the support plate 14 by external bolts, and the rotation of the rotating shaft 2 can drive the gears inside the gear box 22 to rotate, so that the speed of the output shaft 23 is lower than the speed of the rotating shaft 2, and the output shaft 23 can drive the connecting plate 24 and the support rod 3 to rotate in a circle.

[0032] For loading and unloading, for example, Figure 2 As shown, a feed hopper 11 is installed on one side of the outer wall of the upper end of the shell 1, and a discharge pipe 13 is installed on the lower end of the outer wall of one side of the shell 1. The feed hopper 11 and the discharge pipe 13 are both connected to the interior of the shell 1.

[0033] During use, coal material is fed into the feed hopper 11 by an external feeding device, so that the material slides into the shell 1 through the feed hopper 11 , and the crushed and filtered material in the shell 1 can be discharged through the discharge pipe 13 .

[0034] For material filtration, for example, Figure 5 As shown, the filter plate 15 is provided with filter holes 16 distributed in a circular array, and the inner wall of the filter hole 16 is designed in an arc shape.

[0035] During use, the crushed material can be filtered through the filter plate 15 and the filter holes 16 to ensure that the size of the discharged material meets the requirements and the combustion effect of the material is guaranteed.

[0036] In order to crush the material, for example, Figure 1 As shown, the rotating shaft 2 passes through the outer wall of one end of the shell 1 and is provided with a drive motor 12. The drive motor 12 is connected to the outer wall of the shell 1. The outer wall of the rotating shaft 2 is installed with equidistant and parallel crushing knives 21. The crushing knives 21 are located inside the shell 1, and the crushing knives 21 are located at the upper end of the support plate 14.

[0037] In use, the driving motor 12 can drive the rotating shaft 2 to rotate in a circle, so as to drive the crushing knife 21 to rotate in the shell 1, and the crushing knife 21 can cut and crush the material in the shell 1, and the diameter of the material is reduced.

[0038] In order to keep the relative position of the ejection head 34, the piston body 32 is arranged in the sleeve 31, and the spring 33 is arranged on the outer wall of the upper end of the piston body 32. Figure 4 The piston body 32 is elastically connected between the spring 33 and the inner wall of the upper end of the sleeve 31.

[0039] In use, the spring 33 keeps the relative position of the sleeve 31 on the outer side of the supporting rod 3 stable, and the ejection head 34 on the upper end of the sleeve 31 can enter the filter hole 16.

[0040] In order to clean the filter hole 16, the ejection head 34 is arranged on the outer wall of the upper end of the supporting rod 3. Figure 4 The ejection head 34 is designed in a spherical shape, and the size of the ejection head 34 is smaller than that of the filter hole 16.

[0041] In use, when the ejection head 34 moves to the lower end of the filter hole 16, the ejection head 34 can enter the filter hole 16 according to the elastic force of the spring 33, so as to eject the material blocked in the filter hole 16, keep the connectivity of the filter hole 16 and ensure the filtering efficiency of the filter hole 16.

[0042] In order to facilitate unloading, the unloading plate is arranged on the inner wall of the lower end of the shell 1. Figure 1 The unloading plate is designed in an inclined shape.

[0043] In use, the material at the lower end of the shell 1 can slide on the unloading plate, so as to move to the discharge pipe 13, and the unloading of the material is facilitated.

[0044] In use, the coal material is put into the feeding hopper 11 by the external feeding device, so that the material is concentrated and slides into the shell 1 through the feeding hopper 11, the driving motor 12 drives the rotating shaft 2 to rotate in a circle, so that the crushing knife 21 rotates in the shell 1, and the crushing knife 21 can cut and crush the coal in the shell 1, and the size of the coal is reduced.

[0045] The crushed coal is screened through the filter hole 16, so that the coal meeting the size can fall through the filter plate 15, the coal at the lower end of the shell 1 can slide according to the inclination of the unloading plate, and the coal is concentrated and discharged through the discharge pipe 13, and the coal can be conveyed into the subsequent combustion device through the discharge pipe 13.

[0046] According to the driving steps of the rotating shaft 2, the rotating shaft 2 can drive the gears inside the gear box 22 to rotate, and the output shaft 23 can be driven to rotate through the gear box 22. The gear box 22 can reduce the speed of the rotating shaft 2 so that the speed of the output shaft 23 meets the requirements, so that the output shaft 23 can drive the connecting plate 24 to rotate in a circle at the lower end of the support plate 14.

[0047] The ejector head 34 is driven by the support plate 14 to move and enter the filter hole 16. The spring 33 pushes the sleeve 31 and the ejector head 34 to move vertically, so that the ejector head 34 can eject the material blocked in the filter hole 16 through the spring 33.

[0048] When the support plate 14 drives the connecting rod to move continuously, the ejector head 34 contacts the arc surface of the filter hole 16, so that the ejector head 34 is squeezed, and the sleeve 31 overcomes the elastic force of the spring 33 and moves back, so that the ejector head 34 can move out of the filter hole 16, so that the ejector head 34 can move back and forth vertically, and thus follow the circumferential rotation of the support plate 14, which can ensure that the ejector head 34 cleans each filter hole 16.
