What is Automatic Bar Screen?
The Automatic Bar Screen is mainly composed of frame, grating bar, cleaning rake plate, lifting chain, motor reducer device, etc. When working, the dirt cleaning rake plate fixed on the lifting chain is driven by the driving device, and some of the dirt retained in the underwater grille is fished up, and the dirt cleaning rake plate relies on the two sides of the lifting chain from after the grille to before the grille clockwise synchronous rotary movement, when the rake plate to the upper part of the body, due to the role of the steering guide and guide wheel, the dirt falls down by gravity to unload the dirt.
Structure
Body: the frame and rack shield are made of high-strength low-alloy steel welded by hot-dipped galvanization treatment, and the whole spraying epoxy resin for anti-corrosion treatment after welding (according to user requirements can be changed to stainless steel production), beautiful and good anti-corrosion. At the same time, there is a moderate opening door on the shield for easy operation and maintenance, and the opening door is equipped with a latching device.
Traction chain: The traction chain is made of stainless steel to ensure no rust and corrosion in underwater work and maintenance-free. The chain adopts special wide chain plate stainless steel, the safety factor of the chain cannot be too small, and there is a chain tensioning adjustment device. The chain and the chain groove form a closed state, which can effectively prevent the fence slag into the chain groove and avoid the jamming phenomenon.
Driving system: The driving part adopts reducer, the stainless steel transmission mechanism with standard type chain and sprocket device drives the sprocket rotation to ensure that the force transfer chain plate on both sides is balanced, moving upward in parallel on the rectangular track and raking the teeth between the two chain plates slowly upward to rake dirt.
Hook-shaped tooth rake group: rake teeth can be made of stainless steel or nylon, and the use of chains moving on the rail way, the rake teeth upward traction, the rake teeth running speed can not be too large. If the rake teeth are made of nylon materials are die-cast by special molds at once to ensure that the strength of the teeth is not easily deformed.
Guide wheel combination: the lower stainless steel sprocket should be designed to prevent wear and corrosion of the closed shape, the upper sprocket can be adjusted to tension the traction chain.
