8-inch torpedo sand removal net type automatic flushing filter

Abstract

The invention discloses an 8-inch torpedo sand-removing mesh type full-automatic washing filter. A cylindrical filter screen of which two ends are provided with seal rings is arranged at two ends in a tank body by virtue of a ring seat and a cover seat; a plastic torpedo mesh core is arranged in the filter screen by virtue of the cover seat which is provided with a draining valve; the front end of the tank body and a water inlet pipe which is provided with a high-pressure water intake hole are integrated by means of hard connection; the tank body is arranged horizontally; a water outlet pipe which is provided with a vertical short pipe and a low-pressure water intake hole is in flexible connection with the tank body by virtue of a butterfly valve; and the draining valve on the cover seat is connected to an automatic control system including an electromagnetic head by virtue of a water control pipe. The 8-inch torpedo sand-removing mesh type full-automatic washing filter has an automatic cleaning function, does not need manual operation, and has low labor intensity, high efficiency, few overflow boundary condition changes, small head loss and energy conservation; and a parallel back-washing mode is changed into a single direct washing mode, material and annual operation and management costs can be reduced, and conditions are created for merging management irrigation systems and centralized management head system filter stations.

Description

technical field [0001] The invention belongs to industrial and agricultural water-saving filtering devices, in particular to an 8-inch torpedo desanding net type fully automatic flushing filter. Background technique [0002] At present, the industrial water treatment and water-saving irrigation that are being gradually promoted, such as water treatment and drip irrigation in waterworks, have relatively high water quality requirements for domestic water and irrigation water. Impurities and sediment in the water must be filtered out through filters in advance to prevent drip irrigation. With blockage and meet domestic water standards. The traditionally used filters are manual cleaning screen filters and automatic cleaning screen cleaning filters, which are used singly or in parallel. Single-body manual cleaning screen filter If the filter screen is blocked and the water flow is not smooth, stop the water supply and perform manual cleaning, which will affect the normal operati...

AI Technical Summary

Problems solved by technology

Single-body manual cleaning of the mesh filter If the filter mesh is blocked and the water flow is not smooth, stop the water supply and perform manual cleaning, which will affect the normal operation

When the manual screen filters used in parallel need to be cleaned during the working process, one screen filter can be stopped for cleaning first, and the other screen filters are working, and they are manually cleaned in turn; it will reduce the flow rate and work efficiency , time-consuming

Although the automatic cleaning screen filter can realize automatic cleaning of the filter screen, because it is composed of several single screen filters in parallel, it has many components, large volume, changeable water media, and large head loss. The power of the power equipment is large, the operating cost is high, the consumables are uneconomical, and the backwash needs filtered clean water, which increases the water demand for flushing and the additional energy for processing

As a result, the application is not ideal, the superiority of water-saving irrigation technology is not well reflected, and a series of problems such as slow popularization
