Description

[0002] When manually cleaning the power plant boiler, the worker needs to drill into the work site, needs to wear a mask, the entrance is narrow, and it is troublesome to enter and exit. The worker transfers the dust attached to the inside of the boiler to a dust storage bag by using a simple tool, and then transfers the dust in the storage bag to the outside of the work site. Part of the dust has the phenomenon of clumping, which causes a large amount of dust to be generated during the scraping process of the worker, and the worker cannot change the mask in the work site, which causes the worker to need to go out to change the mask after a relatively short period of work, increases the difficulty of the work, and greatly prolongs the working time.

[0003] During the manual cleaning of the power plant boiler, large machinery cannot be used due to the narrow entrance, which makes the cleaning efficiency not high, and the personnel entering and exiting the power plant boiler is troublesome, which greatly slows down the progress of the cleaning work of the power plant boiler, and causes the cleaning efficiency to be unable to be guaranteed.

[0004] When using an air cannon to clean the power plant boiler, the inside of the boiler is impacted by compressed air to wash out the dust of the boiler. This method can only transfer part of the dust in the boiler, and the dust can only be transferred out of the narrow entrance, which causes the dust to be greatly dispersed when being transferred outside the transfer site, causes the personnel to inhale a large amount of dust, and thus causes damage to the body of the personnel.

[0047] The arc-shaped plate 212 is provided with a scraping strip.

[0048] In the present application, the pusher 2015 can be selected as an electric push rod, a hydraulic cylinder and a pneumatic cylinder.

[0049] In the present application, the pusher 2015 can be selected as an electric push rod, a hydraulic cylinder and a pneumatic cylinder.

[0050] Afterwards, the boiler dust collection and processing device is started, the pushing piece 2015 drives the conveying pipe 2011 to move downwards, that is, drives the connecting frame 2012, the second circular table 2013 and the stirring bar 2014 to move downwards, the second circular table 2013 simultaneously slides in the arc-shaped sliding groove 2010a, and the second circular table 2013 drives the stirring bar 2014 to rotate, the stirring bar 2014 breaks the caked dust through rotation, when the conveying pipe 2011 is preliminarily communicated with the air inlet channel 2018, the dust in contact with the bottom of the conveying pipe 2011 is transferred from the air inlet of the conveying pipe 2011 to the air inlet channel 2018, then the dust is transferred from the air inlet channel 2018 to the shunt pipe 2019, the dust continues to be transferred from the shunt pipe 2019 to the gas conveying pipe 2020, the dust in the gas conveying pipe 2020 is transferred to the gas source interface 202, finally the dust is transferred out of the boiler from the gas source interface 202, and the dust raised by the stirring bar 2014 in breaking the dust caking is transferred from the air inlet of the conveying pipe 2011 to the air inlet channel 2018, then the dust is transferred from the air inlet channel 2018 to the shunt pipe 2019, the dust continues to be transferred from the shunt pipe 2019 to the gas conveying pipe 2020, the dust in the gas conveying pipe 2020 is transferred to the gas source interface 202, finally the dust is transferred out of the boiler from the gas source interface 202, the dust caking is broken at the same time, the dust is extracted out of the site, the diffusion of the dust is reduced, the mask worn by the worker can be used for a longer time, the time of the worker staying in the boiler at a single time is increased, and the dust inhaled by the worker in the boiler is reduced, so that the worker is prevented from inhaled a large amount of dust in the boiler for a long time, and the worker's body is prevented from being damaged;

[0051] The conveying pipeline 2011 continues to move downward, and as the conveying pipeline 2011 gradually descends, the upper air inlet of the conveying pipeline 2011 is gradually blocked, and the lower air inlet is gradually opened, the suction force for extracting dust increases, and the suction force for extracting dust decreases, so that the conveying pipeline 2011 can be adjusted according to the drilling condition to use different degrees of extraction. When the upper part of the conveying pipeline 2011 contacts the second connecting seat 210, the second connecting seat 210 starts to move downward, that is, the second telescopic frame 211 and the arc-shaped plate 212 move downward, and the limiting block at the hinge of the second telescopic frame 211 and the arc-shaped plate 212 makes the arc-shaped plate 212 unable to turn inward. When the arc-shaped plate 212 contacts the cylinder in the boiler, the telescopic part 211b starts to contract, and the fixed part 211a starts to turn upward, and the scraping strip on the arc-shaped plate 212 scrapes the dust attached to the cylinder in the boiler, and then the dust scraped off is transferred to outside the site through the conveying pipeline 2011. When the conveying pipeline 2011 is completely connected with the air inlet channel 2018, the conveying pipeline 2011 stops moving downward, and the conveying pipeline 2011 is in a state of continuously extracting dust and transferring the dust to outside the site.

During the transfer process, the worker raises the height of the conveying pipeline 2011, and the conveying pipeline 2011 is still in the state of extraction. The bottom and the upper part of the conveying pipeline 2011 extract dust at the same time, so that the dust in the boiler is reduced, the service life of the worker's mask is improved again, and the possibility of workers inhaling a large amount of dust in a short time is reduced. When the worker places the dust cleaning system in the next area to be cleaned, the pushing member 2015 drives the conveying pipeline 2011 to return to the initial state, that is, the connecting frame 2012, the second circular table 2013 and the stirring strip 2014 return to the initial state.

[0053] After that, the above steps are repeated to complete the dust cleaning work of the boiler. When all the dust in the boiler is cleaned, the worker turns the sliding frame 203 downward, and the sliding frame 203 returns to the initial state.
