Product Description

WASTE WATER TREATMENT MECHANICAL BAR SCREEN

A bar screen is a mechanical filter used to remove large objects, such as rags and plastics, from wastewater. It is part of the primary filtration flow and typically is the first, or preliminary, level of filtration, being installed at the influent to a wastewater treatment plant. They typically consist of a series of vertical steel bars spaced between 1 and 3 inches apart.

Bar screens come in many designs. Some employ automatic cleaning mechanisms using electric motors and chains, some must be cleaned manually by means of a heavy rake. Items removed from the influent are called screenings and are collected in dumpsters and disposed of in landfills. As a bar screen collects objects, the water level will rise, and so they must be cleared regularly to prevent overflow.



WORKING PRINCIPLE
When the rake chain runs to the upper part of the equipment, due to the guiding of the sheave and the curved rail, a relative self-cleaning is generated between each set of rakes, and most of the solid falls by gravity. The other part relies on the reverse movement of the cleaner to clean the impurities sticking to the rakes.

PRODUCT FEATURES
 

1 High degree of automation, high separation efficiency, low power consumption, no noise, good corrosion resistance;

2 Work continuously and stably under unattended operation. Overload safety protection device is set. When the equipment fails, an audible and visual alarm will be        generated and the machine automatically stop, which can avoid overloading the equipment.

3 It can adjust the machine running interval according to user's needs to achieve periodic operation; it can be automatically controlled according to the liquid level difference before and after the screen; and there is manual control function to facilitate maintenance. Users can choose the control type according to different work needs.

4 Low maintenance of the machine,strong self-cleaning and non-blocking capability.
