Alternate treating device of decontaminating filter screens for open channel

Abstract

The invention discloses an alternate treating device of decontaminating filter screens for an open channel, and relates to a decontaminating device. The filter screens are respectively embedded in the upper part and the lower part of a frame, a power motor I is arranged at the top of the frame, the power motor I is in transmission cooperation with chain transmission mechanisms on outer walls on both sides of the frame, and the chain transmission mechanisms drive a sliding beam to move in slide grooves in both sides of the frame; suspension hooks and pushing hands are fixed below the sliding beam, the suspension hooks grasp lifting handles at the upper ends of filter screens, and the pushing hands are propped against the lifting handles; a funnel is hinged to the sliding beam through a suspension arm and positioned on one side of the frame, and a triggering lock device is arranged at the hinged position, and cooperated with upper limits and lower limits, which are arranged at edges on both sides of the frame; a receiving tray is arranged below the funnel, one end of the receiving tray is hinged to supporting legs of the receiving tray, and the other end of the receiving tray is cooperated with the funnel through a pulley mechanism. The alternate treating device disclosed by the invention has the advantages that the design is artful, the cost is low, the alternate treating device is easy to mount, the electric consumption is reduced, the cost is lowered, the efficiency is high, the service life is long, and problems are unlikely to occur.

Description

technical field [0001] The invention relates to a cleaning device, in particular to an alternate treatment device for cleaning and filtering screens in open channels. Background technique [0002] Open channel cleaning usually installs a filter at the entrance of the open channel, but the filter is easily blocked by dirt and the water flow is not smooth. In order to ensure the flow of water, the filter needs to be cleaned frequently, which not only wastes time but also causes a waste of labor. The patent with the publication number CN 202151528 U discloses a sink filter device for removing garbage, which effectively solves the above problems, but also has the following defects: 1. The hoist is used as the power, but the hoist can only provide power when the hanger rises. When descending, it can only rely on the gravity of the hanger itself, which cannot guarantee the smooth movement of the hanger, and the power consumption of the hoist also increases the operating cost of th...

[0002] Open channel cleaning usually installs a filter at the entrance of the open channel, but the filter is easily blocked by dirt and the water flow is not smooth. In order to ensure the flow of water, the filter needs to be cleaned frequently, which not only wastes time but also causes a waste of labor.

The patent with the publication number CN 202151528 U discloses a sink filter device for removing garbage, which effectively solves the above problems, but also has the following defects: 1. The hoist is used as the power, but the hoist can only provide power when the hanger rises. When descending, it can only rely on the gravity of the hanger itself, which cannot guarantee the smooth movement of the hanger, and the power consumption of the hoist also increases the operating cost of the device; 2. The garbage grab depends on the motor control to lift and buckle , the motor not only produces redundant power consumption, but also increases the manufacturing cost and is not as stable as the mechanical trigger device; 3. The spray pipe is fixed in the frame horizontally. When the filter screen and the garbage grab rise to the position of the spray pipe, The sprinkler pipe starts to spray water, so some of the water and dirt may flow back into the drain, resulting in a decrease in work efficiency
