Problems solved by technology

[0003] At this stage, there are three main ways to filter surface water for agricultural irrigation with high impurity content: natural sedimentation, sand and gravel filtration, and mesh filtration; natural sedimentation takes a certain amount of time to make soil, sand, and mineral fragments whose specific gravity is greater than water Debris and other sundries settle at the bottom of the pool. When a large amount of agricultural water is needed in summer, the water consumption cannot be met, and the organic organisms, plastic films, algae and other substances with a specific gravity smaller than water cannot be effectively removed; sand and gravel media filtration The equipment is generally used in combination with a mesh filter on the basis of natural precipitation in a pressure vessel, but the energy loss is large and the self-cleaning effect is not ideal
Relying on the principle of negative pressure, the self-cleaning automatic backwashing screen filter can filter water under closed conditions, but the closed pressure vessel has a limited capacity and a maximum tolerance limit for impurities in the water, and the efficiency of filtering water is limited. The acrobatic content in the water has a greater impact. When the acrobatic content in the water is higher, the filtration efficiency is lower; Not ideal, frequent backwashing is required, greatly reducing irrigation efficiency, especially in flood seasons, usually surface water has a high impurity content, at this time, the filter is easily paralyzed, causing huge losses to agricultural production

Abstract

The invention discloses a horizontal-type double-drum backwashing filter. The horizontal-type double-drum backwashing filter comprises a left side cover plate, a right side cover plate, a coarse filtering drum filter screen, a large particle collecting tank, a fine filtering drum filter screen, a sludge and sand collecting tank, a negative pressure water outlet, a high pressure water inlet, a high pressure jet pipe, a toothed belt, and a driving wheel; the horizontal-type double-drum backwashing filter is placed in water; sewage is delivered through the coarse filtering drum filter screen and the fine filtering drum filter screen successively for filtering; the high pressure jet pipe is arranged to be vertical to water surface, and is used for backwashing of the parts of the coarse filtering drum filter screen and the fine filtering drum filter screen above the water surface; large particle impurities are collected by the large particle collecting tank on the coarse filtering drum filter screen, and small particle impurities such as sludge and sand are collected by the sludge and sand collecting tank on the fine filtering drum filter screen; the drum filter screens are driven by the driving wheel to rotate so as to realize repeat backwashing of the filter screens using the high pressure jet pipe.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a horizontal double-drum backwash filter. Background technique [0002] Due to the shortage of water resources in Northwest China, most crops and trees are gradually irrigated by drip irrigation technology, and the drip irrigation belt has strict requirements on the proportion of impurities allowed in the water, and the filter must meet a certain standard for water quality filtration before it can be used, otherwise the drip irrigation belt will be blocked. [0003] At this stage, there are three main ways to filter surface water for agricultural irrigation with high impurity content: natural sedimentation, sand and gravel filtration, and mesh filtration; natural sedimentation takes a certain amount of time to make soil, sand, and mineral fragments whose specific gravity is greater than water Debris and other sundries settle at the bottom of the pool. When a large amo...
