Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration, and in particular to a flue monitoring device for a waste incinerator. Background Art

[0002] The garbage generated in daily life is generally landfilled or incinerated. During incineration, the fire power generated by the combustion can be used to generate electricity. However, the carbon dioxide, sulfur dioxide, nitrogen oxides, etc. generated during incineration are all acidic gases. They float into the air with the flue gas and cause serious pollution to the environment. It is usually necessary to monitor the flue gas and adopt appropriate treatment methods. The existing incinerator flue monitoring device is fixed by multiple bolts and flanges during installation. The position of the monitoring device after installation is fixed in the flue, and the angle of the monitoring probe cannot be adjusted at will. When monitoring the flue gas in the flue, the probe position may be offset due to improper installation position, resulting in inaccurate measurements. Therefore, designing a flue monitoring device for a garbage incinerator that can be easily adjusted has become a technical problem that needs to be solved urgently. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a flue monitoring device for a garbage incinerator.

[0004] The technical solution of the present utility model is a flue monitoring device of a waste incinerator, comprising a mounting base connected to the flue of the incinerator and a flue gas monitoring mechanism, wherein the inner side of the mounting base is provided with a rotating shaft seat located in the flue, and the outer side is provided with a sealing cover, the rotating shaft seat is connected to an adjustment shaft, one end of the adjustment shaft is connected to a coaxially arranged transmission turbine, the mounting base is also provided with a rotating port matching the transmission turbine, one side of the transmission turbine extends into the sealing cover through the rotating port, the inner shaft of the sealing cover is connected to a driving worm meshing with the transmission turbine, the driving worm is connected to a synchronously rotating driving shaft, and one end of the driving shaft passes through the outside of the sealing cover; the flue gas monitoring mechanism is fixed on the adjusting shaft.

[0005] After adopting the above structure, by rotating one end of the drive shaft extending out of the sealing cover, the drive worm and the drive shaft rotate synchronously, the drive worm drives the transmission turbine to rotate, and the transmission turbine drives the connected adjustment shaft to deflect, thereby changing the monitoring angle of the flue gas monitoring mechanism fixed on the adjustment shaft. The angle of the flue gas monitoring mechanism located inside can be directly adjusted without opening the flue, thereby ensuring the accurate position of the detection probe and improving the accuracy of the monitoring results.

[0006] As a further improvement of the present invention, the drive shaft is provided with an external thread extending along the axis, a positioning nut is screwed onto the external thread, and the positioning nut is provided with a friction layer matching the outer surface of the sealing cover.

[0007] After adopting the above structure, the positioning nut cooperates with the external thread, so that the positioning nut rotates and moves along the drive shaft. The friction layer is pressed onto the sealing cover by the movement of the positioning nut. The interference friction between the friction layer and the outer surface of the sealing cover prevents the drive shaft from rotating, thereby avoiding the drive shaft from rotating due to accidental touch.

[0008] As a further improvement of the present invention, a knob is provided on one end of the drive shaft extending from the sealing cover.

[0009] After adopting the above structure, by arranging a knob at the end of the driving shaft extending out of the sealing cover, it is easier to push the knob to generate force to rotate the driving shaft.

[0010] As a further improvement of the present invention, the sealing cover is provided with a sealing bearing, and the sealing bearing is connected to the driving shaft for cooperative rotation.

[0011] After adopting the above structure, a sealing bearing is provided on the sealing cover to rotate in coordination with the drive shaft, thereby preventing smoke from leaking from the position where the sealing cover is penetrated by the drive shaft.

[0012] As a further improvement of the present invention, one end of the drive shaft is axially connected to the sealing cover, the drive shaft is parallel to the drive worm, and both are provided with coaxially rotating transmission gears, and the transmission gears are meshed with each other.

[0013] After adopting the above structure, a transmission gear that rotates coaxially is set by the drive shaft and the drive worm, and then the transmission gears are engaged with each other for transmission, which improves the flexibility of the drive shaft in the shaft connection position and transmission ratio, so that the drive shaft can be connected in a position that is easier to operate and rotate synchronously with the drive worm at a suitable transmission ratio.

[0017] like Figure 1-Figure 2The flue monitoring device of a waste incinerator shown in the figure includes a mounting base 1 connected to the flue of the incinerator and a flue gas monitoring mechanism 2. The mounting base 1 is provided with a rotating shaft seat 3 located in the flue, and a sealing cover 4 is provided on the outside. The rotating shaft seat 3 is axially connected to an adjustment shaft 5, and one end of the adjustment shaft 5 is connected to a coaxially arranged transmission turbine 6. The mounting base 1 is also provided with a rotating port 7 matching the transmission turbine 6. One side of the transmission turbine 6 extends into the sealing cover 4 through the rotating port 7. The sealing cover 4 is internally connected to a drive worm 8 meshing with the transmission turbine 6. The drive worm 8 is connected to a synchronously rotating drive shaft 9, and one end of the drive shaft 9 passes through the outside of the sealing cover 4; the flue gas monitoring mechanism 2 is fixed on the adjusting shaft 5.

[0018] By rotating the drive shaft 9 to extend one end of the sealing cover 4, the drive worm 8 and the drive shaft 9 rotate synchronously, the drive worm 8 drives the transmission turbine 6 to rotate, and the transmission turbine 6 drives the connected adjustment shaft 5 to deflect, thereby changing the monitoring angle of the flue gas monitoring mechanism 2 fixed on the adjustment shaft 5. The angle of the flue gas monitoring mechanism 2 located inside can be directly adjusted without opening the flue, thereby ensuring the accurate position of the detection probe and improving the accuracy of the monitoring results.

[0019] The drive shaft 9 is provided with an external thread extending along the axis, and a positioning nut 10 is screwed onto the external thread. The positioning nut 10 is provided with a friction layer matching the outer surface of the sealing cover 4 .

[0020] The positioning nut 10 cooperates with the external thread, so that the positioning nut 10 rotates and moves along the drive shaft 9. The friction layer is pressed onto the sealing cover 4 by the movement of the positioning nut 10. The interference friction between the friction layer and the outer surface of the sealing cover 4 prevents the drive shaft 9 from rotating, thereby avoiding the drive shaft 9 from rotating due to accidental touch.

[0021] A knob 11 is provided at one end of the drive shaft 9 extending from the sealing cover 4 .

[0022] By arranging a knob 11 at the end of the driving shaft 9 extending out of the sealing cover 4 , it is easier to push the knob 11 to generate force to rotate the driving shaft 9 .

[0023] The sealing cover 4 is provided with a sealing bearing 12 , and the sealing bearing 12 is connected to the driving shaft 9 for cooperative rotation.

[0024] A sealing bearing 12 is provided on the sealing cover 4 to rotate in coordination with the drive shaft 9 , thereby preventing smoke from leaking from the position where the driving shaft 9 penetrates the sealing cover 4 .

[0025] One end of the driving shaft 9 is axially connected to the sealing cover 4 . The driving shaft 9 is parallel to the driving worm 8 , and both are provided with a coaxially rotating transmission gear 13 , and the transmission gears 13 are meshed with each other.

[0026] By setting a transmission gear 13 that rotates coaxially with the drive shaft 9 and the drive worm 8, and then the transmission gears 13 engage with each other for transmission, the flexibility of the drive shaft 9 in the shaft connection position and the transmission ratio is improved, so that the drive shaft 9 can be shaft-connected in a position that is easier to operate and rotate synchronously with the drive worm 8 at a suitable transmission ratio.
