Description

Technical Field

[0001] The utility model belongs to the technical field of waste incineration power generation, and particularly relates to an automatic cleaning device for plastic films on the feed hopper of a waste incineration power plant. Background Technique

[0002] Waste incineration power generation means that after waste is sent into an incinerator through a feed hopper, the waste burns fully, and a large amount of heat generated heats feed water to superheated steam. The high-temperature and high-pressure steam is converted into electric energy after doing work through a steam turbine, thus realizing the power generation process. The feed hopper of a waste incineration power plant is installed on the maintenance platform of a waste crane in a waste pool and is connected to the waste pool wall and the incinerator. When the waste crane operator puts in waste, some waste is likely to fall out from the waste grab bucket and the feed inlet and adhere to the outer wall of the feed hopper, affecting the line of sight of the waste crane operator. At the same time, a large amount of plastic films accumulate on the outer wall. If a fire breaks out in the waste pool or the maintenance platform of the waste crane, it is easy to cause the fire to spread. At present, generally, maintenance personnel manually enter the maintenance platform of the waste crane and use tools to manually clean the plastic films adhering to the outer wall of the feed hopper. Since the outer wall of the feed hopper is usually dozens of meters high, manual cleaning is rather inconvenient and the cleaning efficiency is not high. In particular, it is more difficult to clean the drooping plastic films. At the same time, the waste pool belongs to a confined space, and there are relatively large personal safety risks for maintenance personnel to frequently enter the confined space for operation. Content of the Utility Model

It has the advantages of being able to adjust the height of the cleaning scraper, being relatively flexible to use, and being able to cut the plastic film when the cleaning scraper scrapes the plastic film adhering to the wall, effectively improving the cleaning effect of the outer wall of the feed hopper, replacing the manual operation method, realizing automatic cleaning, and reducing the safety risks caused by the frequent entry and exit of operators into the waste pool.

A cleaning scraper 12 and an elastic cutting assembly 13 are fixedly installed on the swinging block 10, and the elastic cutting assembly 13 is located on both sides of the cleaning scraper 12. During use, control the electric telescopic push rod 8 to make the U-shaped mounting seat 9 drive the swinging block 10 to move forward, so that the cleaning scraper 12 contacts the wall surface. And control the servo motor 11 to start, so that the swinging block 10 drives the cleaning scraper 12 to rotate, so as to adjust the use angle of the cleaning scraper 12. And control the transverse moving mechanism 7 to make the cleaning scraper 12 move, so as to scrape the plastic film adhered to the wall surface. And when scraping the adhered plastic film, the elastic cutting assembly 13 moves along with the cleaning scraper 12, so as to cut the plastic film from both sides of the cleaning scraper 12 to achieve effective cleaning.

[0022] Further referring to Figure 2 , the lifting and adjusting assembly 5 includes a driving motor 501 and a vertical threaded rod 502. The driving motor 501 is fixed on the inner wall of one end of the vertical limiting groove.

When in use, the stepper motor 706 is controlled to be turned on, so that the first connecting rod 703 drives the driving rubber wheel 701 to roll in the slot at the upper end of the transverse slide rail 6, so as to drive the inner plate 705 and the outer plate 707 to move along the transverse slide rail 6, thereby driving the cleaning scraper 12 and the elastic cutting component 13 to move horizontally. When controlling the reciprocating movement of the cleaning scraper 12, the servo motor 11 can be controlled to adjust the angle of the cleaning scraper 12 to meet the reciprocating scraping of the plastic film by the cleaning scraper 12, and the limiting rubber wheel 702 plays a limiting role during the movement to prevent the driving rubber wheel 701 from being disengaged from the slot, and the stability of use is higher.
