Automatic backwashing filtering device for agricultural irrigation

Abstract

The invention discloses an automatic backwashing filtering device for agricultural irrigation. The automatic backwashing filtering device comprises a backwashing filter, wherein a portable type movable flange disc is arranged at one side of the backwashing filter; a backwashing filter side edge fixing plate is arranged at the other side of the backwashing filter; a backwashing filter water inlet pipe is arranged at one side of the top of the backwashing filter; the backwashing filter water inlet pipe is provided with a backwashing filter water inlet; a filter water inlet channel is arranged inthe backwashing filter water inlet pipe below the backwashing filter water inlet; a backwashing filter water outlet pipe is arranged at the other side of the bottom of the backwashing filter. The automatic backwashing filtering device is compact in structure and convenient to use and has practical functions; an isolation pressure-division plate and a water pressure decompression disc are arrangedin a conventional backwashing filtering device and water pressure in the backwashing filter can be alleviated; inner elements are prevented from being damaged and the service life of the automatic backwashing filtering device is prolonged; the post-period maintenance cost is reduced, the working cost is reduced and the working income is indirectly improved.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural equipment, in particular to an automatic backwash filter device for agricultural irrigation. Background technique: [0002] The traditional automatic backwashing filter device has a single internal structure, which is easily damaged when the internal water pressure is too high, and has few functions, which cannot relieve the water pressure inside the backwashing filter, easily causing damage to internal components, and shortening the use of the automatic backwashing filter Life expectancy, increased post-maintenance costs, increased operating costs, and reduced operating income. Invention content: [0003] The object of the present invention is to provide an automatic backwash filter device for agricultural irrigation in order to solve the above problems, which solves the shortcomings in the prior art. [0004] In order to solve the above problems, the present invention provides a technic...
