Most belt
conveyors has scraper on it,that is a very important part for belt conveyor, without
it, the conveyor can not work smoothly.
Conveyor belt is the
most commonly used material handling equipment, which is widely used in
chemical, coal, iron & steel, metallurgy, mining industries, port, thermal
power plant, etc. However, for conveyor belt which runs in the open air without
cover hood, water scraper is a necessary accessory which is used to get rid of
the stagnant water on the belt.
Water
scraper mainly consists of support & frame, idler sets, axle, bearing
block, connecting rod, crank, electric-hydraulic pusher, etc. The operation
precondition of water scraper is conveyor belt non-loading running. In the
operation, press roller, trough carrier idler, flat carrier idler, connecting
rod and crank are workings as a rotary body, the electric-hydraulic pusher
drives the press roller and trough carrier idlers in clockwise rotation, then
the top of trough carrier idlers and flat carrier idlers are on the same
tangent plane. Under the clamping pressure of press roller and carrier idlers,
the belt is lifted up, and the water is discharged from both sides of the
conveyor belt. Thus the shift between normal operation and water removal can be
achieved through the rotation of rotary body. When the conveyor belt is in
normal operation, the trough carrier idlers of water scraper are used as the
part of conveyor belt, so the belt can passes through the water scraper
smoothly.This kind of water scraper has
simple and reliable structure, which can avoid the belt damage. And it has the
features such as safe and reliable operation, long service life, easy
installation and convenient maintenance.
From now on,
you may have a good learn about the water scraper, and many more knowledge in www.pkmachinery.com, please check.
