Its main principle is: coal is sent to the boiler, 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 pneumatic ash conveying technology can be used to drive the dust and smoke in the pipe body to circulate through gas. However, as the ash conveying pipeline continues to work, dust is easily accumulated inside the pipeline, and there is no mechanism for blowing dust on the inner wall of the pipeline, which can continuously act on the inner wall of the pipeline. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an auxiliary cleaning device for an ash conveying pipeline. The supply pipe designed for the auxiliary cleaning device for the ash conveying pipeline can continuously supply gas to the rotating frame, so as to facilitate blowing gas into the pipe body.

[0004] An auxiliary ash cleaning device for an ash conveying pipeline comprises a pipe body, and is characterized in that: a supply pipe is arranged inside the pipe body, a control pipe is slidably arranged on the lower surface of the supply pipe, a rotating mechanism is arranged below the supply pipe, the rotating mechanism comprises a rotating frame and a driving ring, a control pipe is slidably arranged on the upper surface of the rotating frame, a driving groove is provided on the surface of the driving ring, a driving ring is overlapped on the surface of the driving groove, a main spring is arranged between the control pipe and the pipe body, the rotating frame is rotatably arranged on the lower surface of the supply pipe, a spray outlet is provided at the bottom of the control pipe, and a scraper is provided on the edge of the rotating frame.

[0005] The above technical solution has the following beneficial effects:

[0006] The supply pipe designed in this scheme can continuously supply gas to the rotating frame, which is convenient for blowing gas into the inside of the pipe body, so as to blow away the dust on the inner wall of the pipe body and scrape off the dust on the inner wall. The setting of the auxiliary pipe that can continuously input gas can drive the control pipe to move downward, so that the control pipe drives the rotating frame to rotate in one direction, and the control scraper scrapes off the dust on the inner wall of the pipe body, and can compress the gas inside the control pipe to reach a certain position for discharge, so that the bottom of the control pipe can discharge gas, which can also play an auxiliary cleaning effect.

DETAILED DESCRIPTION

[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 auxiliary dust cleaning device for dust conveying pipelines, as shown in the attached Figure 1-5 As shown in the instruction manual, Figure 5Only the rotating frame 4 and the driving ring 5 are shown, and the bottom of the rotating frame 4 is cut, and this perspective is also viewed upside down. The tube body 1 represents a normal ash conveying pipeline, and the ash conveying direction is from top to bottom. This solution has two groups of tubes that need to be injected with gas, namely the supply tube 2 and the auxiliary tube 11. The supply tube 2 is mainly supplied to the rotating frame 4, because the rotating frame 4 is rotatably arranged below the supply tube 2, and the top and the control tube 3 are sealed and slid, and the upper surface of the control tube 3 is provided with an annular air inlet channel 17, and the air inlet channel 17 is connected to the internal channel 18, so as to achieve the effect of supplying gas to the scraper 9, and the auxiliary tube 11 is discharged to the No. 1 hole 12. When the No. 1 hole 12 and the No. 2 hole 13 correspond, gas is supplied to the nozzle 8. This is the supply of two groups of tubes. The supply pipe 2 and the auxiliary pipe 11 of the present invention can be connected to an external jet device, such as an air compressor and a fan. The present invention has a variety of sealing structures, which are introduced one by one below. They are a rotating frame 4 and a control pipe 3. The bottom middle part of the rotating frame 4 and the control pipe 3 are sealed structures. The control pipe 3 can slide in a sealed manner in the middle part of the rotating frame 4, and the top of the rotating frame 4 is also sealed and slidable with the control pipe 3. The control pipe 3 and the supply pipe 2 are also sealed and slidable. The bottom of the auxiliary pipe 11 and the connecting pipe 10 are also sealed and slidable. The existing sealed sliding can be achieved by setting a sealing ring of a corresponding shape at the circular contact part. The present invention is introduced below. Since the supply pipe 2 and the auxiliary pipe 11 both realize the continuous input of gas, the supply pipe 2 is naturally input to the rotating frame 4. The rotating frame 4 completes the discharge of the scraper 9, while the auxiliary pipe 11 is different. Since the No. 1 hole 12 of the auxiliary pipe 11 is blocked by the connecting pipe 10, the auxiliary pipe 11 cannot discharge the gas. Since the auxiliary pipe 11 continuously supplies gas, the control pipe 3 is continuously moved downward under the condition of gas compression until the No. 1 hole 12 and the No. 2 hole 13 correspond to each other. At this time, the compressed gas passes through the No. 1 hole 12 and the No. 2 hole 13 to reach the ejection port 8 at the bottom, completing the impact on the side of the tube body 1. As the gas is discharged, the control pipe 3 will reset upward under the reset of the main spring 7, completing a cycle of action, that is, the control pipe 3 will move up and down. This solution utilizes the up and down movement of the control pipe 3 to drive the rotating frame 4 to rotate, because the rotating frame 4 is provided with a driving ring 5 for internal rotation, and the bottom of the control tube 3 is just overlapped on the driving ring 5 (a driving groove 6 is designed on the driving ring 5, and the bottom of the control tube 3 is overlapped on the driving groove 6, so the control tube 3 moves downward to cause the driving ring 5 to rotate, and the driving ring 5 and the rotating frame 4 form a set of one-way rotation mechanism, so that the control tube 3 moves downward to drive the rotating frame 4 to rotate, and the control tube 3 moves upward The one-way block 14 slips on the surface of the one-way groove 15), the control tube 3 moves downward to drive the rotating frame 4 to rotate, and the control tube 3 resets upward without driving the rotating frame 4 to rotate. A positioning block 20 is also provided above the rotating frame 4. The positioning block 20 can make the rotating frame 4 temporarily stable during the rotation process. The springs of this scheme are all in the original length state of the spring in the figure.The vertical distance between the No. 1 hole 12 and the No. 2 hole 13 is the vertical distance between the upper and lower driving grooves 6, which is the overall effect of the present scheme. A supply pipe 2 is arranged inside the tube body 1, and a control pipe 3 is slidably arranged on the lower surface of the supply pipe 2. A rotating mechanism is arranged below the supply pipe 2, and the rotating mechanism includes a rotating frame 4 and a driving ring 5. The control pipe 3 is slidably arranged on the upper surface of the rotating frame 4, and a driving groove 6 is provided on the surface of the driving ring 5. The driving ring 5 is overlapped on the surface of the driving groove 6. A main spring 7 is arranged between the control pipe 3 and the tube body 1. The rotating frame 4 is rotatably arranged on the lower surface of the supply pipe 2, and a spray port 8 is provided at the bottom of the control pipe 3. A scraper 9 is provided at the edge of the rotating frame 4. A connecting pipe 10 is arranged inside the control pipe 3, and an auxiliary pipe 11 is slidably arranged in the middle of the connecting pipe 10. The auxiliary pipe 11 is fixedly arranged inside the supply pipe 2, and a No. 1 hole is provided at the bottom of the auxiliary pipe 11 12, a No. 2 hole 13 is provided on the top of the connecting pipe 10, the driving ring 5 is rotatably arranged in the middle of the rotating frame 4, a one-way block 14 is slidably arranged on one side of the driving ring 5, a one-way groove 15 is provided on the inner wall of the rotating frame 4, a one-way block 14 is overlapped on the surface of the one-way groove 15, a No. 1 spring 16 is arranged between the one-way block 14 and the driving ring 5, an air inlet channel 17 is provided on the upper surface of the control pipe 3, an internal channel 18 is provided inside the rotating frame 4, a positioning groove 19 is provided on the upper surface of the rotating frame 4, a positioning block 20 is provided on the lower surface of the supply pipe 2, a positioning groove 19 is overlapped on the surface of the positioning block 20, and a No. 2 spring 21 is arranged above the positioning block 20, the number of scrapers 9 is four, and exhaust holes are provided on the surface of the scrapers 9 (the exhaust holes are distributed on the left and right sides and below the scrapers, and can act on the inside of the pipe and the inner wall of the pipe), and a slideway is provided on the inner wall of the supply pipe 2. ,
