Description

At present, most thermal power plants have completed deep peak-shaving transformation. Under peak-shaving conditions, the operating load of the unit will be as low as 30% BMCR. Under this state, the operating efficiency of the main rotating equipment of the boiler is extremely low and the economy is extremely poor. In order to solve the problem of low efficiency of rotating equipment under medium and low loads, one of the solutions is to add a variable frequency speed regulation device, but this will lead to the problem of overheating and cooling of the inverter.

[0003] In the process of cooling the inverter, air circulation is mostly used for cooling. During the cooling process, we found a problem. There is a lot of dust in the outside air.

[0054] The transmission mechanism 101 includes a mounting housing 101a, a motor 101b, a rotating rod 101c, a driving gear 101d, a driven gear 101e and a first bevel gear 101f.

The air pipe assembly 105 connected thereto extracts air, and the dust is extracted into the inner cavity of the protective shell 103f and discharged, thereby extracting and processing the dust generated by the filter plate during the cleaning process.

[0060] There are two fifth bevel gears 103e, which are respectively arranged at both ends of the output rod 103c. The fourth bevel gear 103d is meshed with the fifth bevel gear 103e located in the inner cavity of the protective shell 103f, and the other fifth bevel gear 103e is meshed with the first bevel gear 101f. Through the meshing of the fifth bevel gear 103e and the first bevel gear 101f, a mechanical transmission force is obtained, thereby causing the forward blowing fan 103a to rotate to extract air.

[0061] The storage mechanism 104 includes a dust collecting bin 104a, a first connecting pipe 104b, a dust collecting hopper 104c, a filter cartridge 104d, a cleaning rod 104e, a sixth bevel gear 104f and a seventh bevel gear 104g.

[0062] One end of the cleaning rod 104e is bent to form an L-shaped strip 104e-1, and a cleaning brush 104e-2 is installed on the surface of the L-shaped strip 104e-1. The L-shaped strip 104e-1 and the cleaning brush 104e-2 are in close contact with the surface of the filter cartridge 104d. Through the opening of the L-shaped strip 104e-1 and the cleaning brush 104e-2, the surface of the filter cartridge 104d can be cleaned better, thereby preventing dust accumulation on the surface of the filter cartridge 104d from affecting its use effect.

[0063] There are two air pipe assemblies 105, which are respectively arranged on the outside and inside of the inverter compartment air inlet 201.

[0064] The air pipe assembly 105 includes an annular pipe 105a, a nozzle 105b and a vertical pipe 105c. One end of the nozzle 105b is connected to the annular pipe 105a. The nozzle 105b is inclined.

[0065] Example 3

[0066] Reference Figures 9-10 , which is the third embodiment of the present invention, is based on the above two embodiments and provides an inverter optimized cooling air intake cleaning structure in a small space.

[0067] The filter cartridge 104d is arranged in the inner cavity of the dust collecting bin 104a, and an exhaust air duct K is arranged on the surface of the dust collecting bin 104a. The air containing dust is filtered by the filter cartridge 104d and then discharged to the outside along the exhaust air duct K to prevent dust from splashing and affecting the environment.

[0068] The fan blades of the back-blowing fan 102a and the forward-blowing fan 103a are installed in opposite directions. By determining the installation directions of the two, the air outlet and air inlet directions of the cleaning module 100 can be guaranteed. The back-blowing fan 102a blows out air for cleaning, and the forward-blowing fan 103a absorbs air for dust collection, making the equipment more convenient and environmentally friendly.

[0069] The dust collecting hopper 104c is installed at the bottom of the dust collecting bin 104a. A dust discharge pipe J is provided at the bottom of the dust collecting hopper 104c. A hand valve is installed on the surface of the ash discharge pipe J. The dust collected by the dust collecting bin 104a is stored by the dust collecting hopper 104c.

[0070] A particle sensor H is installed in the inner cavity of the first connecting tube 104b, one end of the first connecting tube 104b is connected to the dust collecting bin 104a, and the other end of the first connecting tube 104b is connected to the protective shell 103f. Through the connection of the first connecting tube 104b, dust carried by air is extracted and directly enters the dust collecting bin 104a for collection, thereby preventing dust from spreading and affecting the environment.

[0071] The steps of cleaning the filter plate of the present invention are as follows:

[0072] 1. The driving gear 101d is driven to rotate by starting the motor 101b, the driven gear 101e is driven to rotate by the rotation of the driving gear 101d, the rotating rod 101c is driven to rotate by the rotation of the driven gear 101e, the first bevel gear 101f is driven to rotate by the rotation of the rotating rod 101c, and the second bevel gear 102d and the fifth bevel gear 103e are driven to rotate by the rotation of the two first bevel gears 101f;

[0073] Second, in the back-blowing mechanism 102, the second bevel gear 102d is rotated to drive the connecting rod 102c to rotate, and the second bevel gear 102d at the other end is rotated by the rotation of the connecting rod 102c, and then the third bevel gear 102e is rotated, and the movable shaft 102b is rotated by the rotation of the third bevel gear 102e, and the back-blowing fan 102a is rotated by the rotation of the movable shaft 102b, so that the air enters the inner cavity of the equipment along the through groove at the bottom of the installation frame 102f, and finally enters the inner cavity of the annular pipe 105a installed in the room along the vertical pipe 105c, and is sprayed out by the nozzle 105b to back-blow the filter plate, so that the dust on the surface of the filter plate is affected by the air and scattered;

[0074] 3. In the absorption mechanism 103, the output rod 103c is driven to rotate by the rotation of the fifth bevel gear 103e, and the fourth bevel gear 103d at the other end is driven to rotate by the rotation of the output rod 103c, and the transmission shaft 103b is driven to rotate by the rotation of the fourth bevel gear 103d, and then the positive blowing fan 103a is driven to rotate, and the air is extracted by the rotor of the positive blowing fan 103a, and the dust discharged by the filter plate carries the air into the inner cavity of the annular pipe 105a through the nozzle 105b, and finally enters the inner cavity of the protective shell 103f through the vertical pipe 105c, and finally enters the inner cavity of the dust collecting bin 104a through the first connecting pipe 104b;

[0075] 4. In the storage mechanism 104, as the air circulates, the air is filtered through the filter cartridge 104d and then discharged along the exhaust air duct K, and the dust remains on the surface of the filter cartridge 104d. The rotation of the transmission shaft 103b drives the seventh bevel gear 104g to rotate, and the rotation of the seventh bevel gear 104g drives the sixth bevel gear 104f to rotate, and the rotation of the sixth bevel gear 104f drives the cleaning rod 104e to rotate, and the rotation of the cleaning rod 104e drives the L-shaped bar 104e-1 and the cleaning brush 104e-2 to rotate, and then the dust on the surface of the filter cartridge 104d is swept off and falls into the inner cavity of the dust collecting hopper 104c for collection. The particle sensor H senses the change of dust in the air, outputs a signal, stops the motor 101b, and completes the cleaning.

[0076] In the heat dissipation process of the inverter room, before the application of the present invention, the cost of using and replacing the filter plate is as follows:
