Technical Field

[0001] The utility model belongs to the technical field of pneumatic ash conveying, and in particular relates to an ash conveying ejector. Background Art

[0002] Coal-fired thermal power generation is the main form of power generation in my country. Its main principle is: coal is sent to the boiler, and the chemical energy of the coal is converted into heat energy in the boiler and absorbed by water and water vapor. The steam does work in the turbine and is converted into mechanical energy. The turbine drives the generator rotor to rotate and converts the mechanical energy into electrical energy and transmits it to the user. In coal-fired thermal power generation technology, a large amount of dust is generated when the fuel is burned. The existing technology of pneumatic ash conveying can be used to circulate dust and smoke in the pipe body through gas. Injectors need to be set at intervals inside the ash conveying pipeline to ensure that the dust flow inside the ash conveying pipeline is guided. After the existing injectors are used for a period of time, dust is easy to accumulate on one side of the injector, affecting the normal exhaust gas. Utility Model Content

[0013] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 5 The embodiments are described in detail.

[0014] This embodiment provides an ash delivery ejector, as shown in the attached Figures 1 - 5 As shown in the instruction manual, Figure 1 The main structure diagram of the body 1 is shown in the figure. The body 1 is located inside the ash conveying pipeline. Figure 2 The structure diagram of the body 1 shows that the present invention has two gas-filling interfaces (both interfaces require external equipment), one is at one end of the injection pipe 2, and the other is the interface on the top of the body 1. Figure 3 Attached to the instruction manual Figure 2 Partial diagram of the manual Figure 4The left side of the body 1 is cut. The injection pipe 2 is the main injection mechanism of this solution. That is, during long-term use, dust is likely to adhere to the surface of the injection port 19 during use, resulting in easy blockage of the injection port 19. In this solution, the injection head 3 is cleaned by simultaneously ventilating the interface above the body 1. Because a sealing ring 4 is provided inside the body 1, the sealing ring 4 prevents the interface above the body 1 from discharging. And the sealing ring 5 of this solution is slidably arranged between the pipe body and the injection pipe 2. The support rod 14 is installed inside the gas to facilitate the sliding of the sealing ring 5. Therefore, gas is continuously input into the interface above the body 1. Driven by the gas compression, the sealing ring 5 moves to the right (that is, the first spring 15 is stretched. As shown in the attached instructions of the specification Figure 5 As shown, when gas is continuously added, the sealing ring 5 will move to the right. And there is a slope inside the body 1. This slope can cause the sealing ring 5 to release gas when it moves a certain distance. Because the diameter of the sealing ring 5 is limited, the gas will enter the air inlet 18 along the edge of the sealing ring 5. Since the delivery pipe 6 and the sealing ring 4 are in sealed sliding, the gas enters from the air inlet 18 through the delivery pipe 6 and is delivered to one side of the rotating disk 10. And the rotating disk 10 and the corresponding disk 13 are also in sealed sliding. Therefore, the added gas can be discharged to the annular gap and ejected onto the surface of the injection port 19. You can refer to the attached instructions of the specification Figure 3 for viewing. It should be noted that an annular channel is provided on one side of the rotating disk 10. This channel can communicate with the annular gap. This is the first effect of this solution. The gas can be driven by continuously adding gas to the body 1 to drive the sealing ring 5 to move and be discharged near the annular gap). The compressed gas reaches the annular gap after release and blows the surface of the injection head 3. During this process, the driving strip 7 moves towards the rotating disk 10. One side of the driving strip 7 is connected to the lower part of the sealing ring 5. It cannot be seen from the figure because the attached instructions of the specification Figure 2 cuts one side of the driving strip 7. And the driving strip 7 just turns to one side of the driving wheel 8 at one side. This perspective cannot be shown. And the attached instructions of the specification Figure 4The top of the driving strip 7 is cut, so it shows a suspended state. However, it should be noted that the driving strip 7 is integrally arranged on the sealing ring 5. In the previous step, the sealing ring 5 slides and moves, so the driving strip 7 of the solution will also move. One side of the driving strip 7 meshes with the driving wheel 8, so that the driving wheel 8 rotates. One side of the driving wheel 8 is rotatably provided with a one-way block 11 and has a torsion spring 17 for resetting. Therefore, under the drive of the one-way block 11, the rotating wheel 9 rotates (one side of the rotating wheel 9 is a ratchet, and a one-way mechanism is formed between this ratchet and the one-way block 11. The other side of the rotating wheel 9 is a face gear, and the face gear meshes with the rotating disk 10, so that the rotating disk 10 rotates). The rotation of the rotating wheel 9 can drive the rotating disk 10 to rotate. When the rotating disk 10 rotates, the wiper 16 on one side will rotate to scrape the dust on the surface of the spray head 3. After the sealing ring 5 discharges the gas, the internal pressure decreases, and it resets to the initial position under the action of the first spring 15, that is, the driving strip 7 will reset. When the driving strip 7 resets, the one-way block 11 will slip on the surface of the rotating wheel 9, that is, the rotating disk 10 of this solution will rotate in one direction. In the middle of the device body 1, there is a spraying mechanism, which includes a spray pipe 2 and a spray head 3. The spray pipe 2 is integrally arranged inside the device body 1, and one side of the spray pipe 2 is integrally provided with a spray head 3. Inside the device body 1, there is a cleaning mechanism, which includes a sealing ring 4, a sealing ring 5, a conveying pipe 6 and a driving strip 7 (one side of the conveying pipe 6 passes through the bracket supporting the spray head 3, and the two are slidably arranged). The sealing ring 4 is slidably arranged inside the device body 1. The upper side of the sealing ring 5 is integrally provided with a conveying pipe 6, and the lower side of the sealing ring 5 is integrally provided with a driving strip 7. One side of the driving strip 7 is provided with a driving mechanism, which includes a driving wheel 8 and a rotating wheel 9. The rotating disk 10 is rotatably arranged inside the device body 1. One side of the rotating wheel 9 meshes with the rotating disk 10. The surface of the rotating wheel 9 is lapped with a one-way block 11. The one-way block 11 is rotatably arranged on one side of the driving wheel 8. The driving wheel 8 is rotatably arranged inside the device body 1. The rotating wheel 9 is rotatably arranged inside the device body 1. An air inlet channel 12 is opened on one side of the rotating disk 10. The corresponding disk 13 is rotatably arranged on the surface of the air inlet channel 12. One side of the corresponding disk 13 is integrally provided with a conveying pipe 6. A support rod 14 is integrally arranged inside the device body 1. A first spring 15 is arranged between the support rod 14 and the sealing ring 5. A wiper 16 is arranged on the surface of the rotating disk 10. One side of the wiper 16 is provided with a spray head 3. One side of the driving wheel 8 meshes with the driving strip 7. One side of the one-way block 11 is provided with a torsion spring 17. One side of the conveying pipe 6 is provided with an air inlet 18. One end of the air inlet 18 is communicated with the corresponding disk 13. A spray outlet 19 is opened on one side of the spray head 3. An annular notch 20 is arranged at the inner arc of the rotating disk 10.
