Abstract

The invention relates to an automatic vertical back-washing device. The device comprises a cylinder which is provided with a water inlet, a water outlet and a drainage port, and a filter screen is arranged in the cylinder. The device is characterized by vertical design, and the water inlet is arranged at the lower part of the cylinder wall and is provided with an inlet valve; the water outlet is arranged at the upper part of the cylinder wall and is provided with an outlet valve; the drainage port is arranged at the lower part of the other side of the cylinder opposite to the water inlet, and is provided with a drainage valve; the cylinder is hermetically equipped with a cylinder cover, the center of the cylinder cover is provided with a back-washing port and a back-washing port valve; the filter screen is a detachable double-layer compound filter screen, non-woven fabrics are filled between the double-layer filter screen, the bottom edge of the compound filter screen is fixed at the bottom of the cylinder, and the top end position of the compound filter screen is higher than the water outlet; and a movable separator is arranged at the position of the water inlet in the cylinder, and the movable separator is a hinge structure; a fixing hinge of the movable separator is fixedly arranged at the bottom of the cylinder, and is connected with a movable hinge by a hinge connection pin.

Description

technical field [0001] The invention relates to water purification treatment equipment technology in water supply systems, in particular to an automatic vertical backwashing device for water purification treatment in industrial and agricultural water supply systems. Background technique [0002] Water purification treatment in industrial and agricultural water supply systems generally adopts the method of installing a filter screen in front of the pipeline. There are still some small impurities in the water treated by this method, such as: small particle suspended solids, sediment and so on. When they accumulate to a certain extent in the water supply system and are not removed, it will reduce the flow area of ​​the pipeline, eventually causing blockage, and in severe cases, it will shut down, posing a great threat to safe operation. Therefore, it is necessary to install backwashing devices in pipelines (especially large-diameter pipelines). So people began to apply backwa...
