Stacker-reclaimer scraper chain full-automatic lubricating system and working method

Abstract

The invention discloses a stacker-reclaimer scraper chain full-automatic lubricating system and a working method thereof, and belongs to the technical field of lubricating systems. The system comprises a lubricating oil pump connected with a lubricating oil station; the lubricating oil pump is connected with a one-way valve; the one-way valve is connected with an overflow valve and an electromagnetic reversing valve; the electromagnetic reversing valve, an oil filter and a throttling valve are connected in sequence; the throttling valve is connected with a progressive distributor; the progressive distributor is connected with an oil-gas mixer; and the oil-gas mixer is connected with a lubricating pipeline, and is connected with an air compressor or a compressed air source. When scraper chain joints are lubricated, oil layers are formed between scraper chain rollers and chain box wear preventing plates to prevent hard friction between the chain rollers and the chain box wear preventingplates, so that the service life of scraper chains and chain boxes is prolonged, the operation noise is reduced, and electric energy is saved. The system is stable in operation, excellent in lubricating effect, high in season adaptability, low in environmental pollution and low in failure rate, and reduces the labor intensity of maintainers.

Description

technical field [0001] The invention relates to an automatic lubricating system of a stacker-reclaimer, belonging to the technical field of lubricating systems. Background technique [0002] Compared with the traditional strip-shaped coal storage yard, the circular closed coal yard has many advantages such as small footprint, high site utilization rate, environmental protection, and strong ability to adapt to bad weather. Most thermal power plants, especially newly-built power plants, use Circular closed coal yard, a stacker and reclaimer is installed in the circular closed coal yard as the equipment for stacking and taking coal, and the scraper machine is the equipment used by the stacker and reclaimer to take coal. A circular closed coal yard with a diameter of 90 meters The length of the scraper arm of the stacker-reclaimer is about 38.5 meters. About 90 sets of scrapers are installed on each scraper machine. If the lubrication effect is not good, it will cause many prob...

[0002] Compared with the traditional strip-shaped coal storage yard, the circular closed coal yard has many advantages such as small footprint, high site utilization rate, environmental protection, and strong ability to adapt to bad weather. Most thermal power plants, especially newly-built power plants, use Circular closed coal yard, a stacker and reclaimer is installed in the circular closed coal yard as the equipment for stacking and taking coal, and the scraper machine is the equipment used by the stacker and reclaimer to take coal. A circular closed coal yard with a diameter of 90 meters The length of the scraper arm of the stacker-reclaimer is about 38.5 meters. About 90 sets of scrapers are installed on each scraper machine. If the lubrication effect is not good, it will cause many problems such as high operating current of the scraper machine, high operating noise, waste oil pollution of the environment, and reduced service life of the scraper machine chain. Therefore, it is necessary to develop a set of efficient, energy-saving and environmentally friendly stacker-reclaimer The scraper chain automatic lubrication system is very important

[0003] Conventional stacker-reclaimer scraper chain lubrication devices generally use self-weight drip lubrication. The working process of the self-weight drip lubrication system is that the scraper machine is started, and the solenoid valve of the self-weight drip lubrication system is opened. Under the action, the oil tank drips to the chain joints of the scraper machine through the pipeline. Due to the working principle, the self-weight drip lubrication system can only lubricate the chain at the tail of the scraper machine, and the lubrication effect is not ideal, and the consumption of lubricating oil is large. There are many shortcomings such as the inability to use it normally in winter, and some enterprises have already abandoned the system
