Description

Scraper for mud and coal conveying belt

Technical Field

The utility model relates to an engineering machine tool technical field, more specifically says that it relates to a defeated mud, defeated coal belt scraper.

Background

The conveying belt is a conveying device universally existing in industrial places, has the advantages of simple structure, convenience in maintenance and large conveying capacity, and is characterized by almost becoming the most main mode of fuel supply in a thermal power plant. With the falling of dry sludge drying and burning projects, most power plants select sludge co-combustion to make contribution to the consumption and the resource of organic solid wastes. However, due to the viscosity of the sludge, the prior scraper blades of the conveyor belt coal plough, the sweeper and the discharger do not meet the requirement any more, and a large amount of sludge is adhered above the belt, so that the preparation of the metering equipment is influenced and the challenge of on-site sanitation and hygiene is brought. Traditional coal ploughs, sweepers and dischargers do not have specific scrapers, and are usually connected with a lifter by adopting stainless steel, rubber and cast iron. The poor damage to the belt of toughness is great, receives the influence of mud viscidity in the actual project of a certain steam power plant coal-fired mixed combustion mud, and the fuel can not separate completely at the conveyer belt head, and a large amount of mud scatters in the below of conveyer belt return stroke, the unnecessary labour that increases. In addition, sludge just after drying has certain sludge, and is cooled by the belt, so that the effect of rolling snow balls is easily produced on the belt, the cohesiveness of the belt is increased after air drying, and the wear sections of stainless steel, cast iron and other materials easily cause tensile damage to the belt, so that the overall effect is poor. Accordingly, the utility model provides a defeated mud, defeated coal belt scraper.

The invention will be further described with reference to the drawings and preferred embodiments.

Example 1

Referring to fig. 1 to 3, the scraper for a mud and coal belt according to the present embodiment includes a scraper support 100, and a scraper blade 200 detachably connected to the scraper support 100;

the scraper support 100 is provided with a jack 101, the scraper blade 200 is provided with a connecting column 201 matched with the jack, and the connecting column 201 and the scraper blade 200 are of an integrated structure and are made of polyurethane materials;

the longitudinal section of the scraper blade 200 is fan-shaped, the scraper blade 200 is provided with a scraping straight side surface 202, a connecting straight side surface 203 and a transition arc surface 204, and the connecting column 201 is arranged on the connecting straight side surface 202.

Further, the doctor blade holder 100 is made of stainless steel.

In this embodiment, through installing scraper blade 200 that has certain intensity and certain toughness's polyurethane material on scraper support 100, make and connect straight side 203 as the face of wiping, its blade department has suitable intensity, also because of polyurethane material has elasticity additional, makes the in-process of wiping, and slight deformation can take place in the blade position, waits that the deformation resets and can produce high-frequency vibration, can shake off the peat of staying on the blade, is convenient for clear up the maintenance.
