Filter belt self balance deviation rectifying device

Abstract

The present invention is one filter belt self-balancing corrector in sludge treating apparatus. The filter belt self-balancing corrector has a correcting signal generator with solenoid valve connected through pipe to the cylinder of the correcting executor, a correcting roller with one end possessing roller capable of shifting along a guide rack and the other end hinged via sliding bearing to a fixing seat, photoelectronic switches on seats on two sides of the filter belt and with output signals fed to the signal input of the electromagnetic directional valve. The present invention adopts no-contact filter belt deviation detecting technology, can avoid edge bending, scratching and tearing of the filter belt, and results in raised reliability and stability.

Description

technical field

[0001] The invention relates to sludge treatment equipment in the field of environmental protection, in particular to a filter belt guide device that must be equipped with a belt-type thickening and pressing integrated machine. Background technique

[0002] With the continuous progress of society and the rapid development of modern cities, the problem of environmental pollution has become increasingly prominent, and the pollution of water sources on which all things depend has become more serious. For this reason, the country has increased its efforts to control water pollution. Municipal sewage and industrial wastewater must be treated up to standard before being discharged into rivers and lakes. A large amount of sludge is bound to be produced during the sewage treatment process; the sludge has high water content and large volume, and generally must be dehydrated and volume-reduced first. Therefore, as one of the sludge treatment equipment, the belt thicke...
