Vertical backwashing filter device

Abstract

The invention provides a vertical backwashing filter device. The vertical backwashing filter device comprises a filter screen cylinder, and a water inlet pipeline and a water outlet pipeline which arearranged on the filter screen cylinder, a vertical middle separator plate divides the internal of the filter screen cylinder into a left chamber and a right chamber, each of the left chamber and theright chamber is filled with a filter material, the water inlet pipeline is arranged at the bottom of the filter screen cylinder, the water outlet pipeline is arranged on the top surface of the filterscreen cylinder, and the water inlet pipeline is provided with a water pump; and the filter screen cylinder is supported by a support. The backwashing device designed in the invention has a simple and reasonable structure, and integrates filtering and backwashing, adopts a bottom-to-top filtering mode and a top-to-bottom backwashing mode adopted in the invention ensure that a filtering element isnot obstructed by impurities, precipitating downwards under the action of gravity and accumulating, in water to be filtered, and facilitate the backwashing operation.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a vertical backwash filter device. Background technique [0002] For Xinjiang and even the entire northwest region, the weather is relatively hot, water resources are relatively scarce, and the demand for water is great. The utilization of surface water resources is very important, but some water sources with high sand content or a large amount of impurities To be used in agricultural and industrial production, it must be filtered by a filter device. After reaching a certain standard, it can enter the drip irrigation system to irrigate crops or the industrial production water system, otherwise it will block the drip irrigation belt and affect industrial production. In order to prolong the service life of the filter elements in the filter device, today's backwash filters mostly use backwash fluid to backwash the filter elements to flush out the particles in the pores.

AI Technical Summary

Problems solved by technology

When the filter of the present invention is working, it is generally filtered from top to bottom. The impurities in the water to be filtered are precipitated and accumulated downward due to the action of gravity, which will easily cause the pores of the filter element to be blocked, and it takes a long time to clean the filter cartridge.

[0006] To sum up, the water intake method of the existing backwash filter is mostly "top-down". The efficiency of water is greatly affected by the content of impurities in the water. Not only the cleaning effect is not ideal, but also the impurities need to be cleaned repeatedly, which greatly reduces the filtration efficiency of water and thus reduces the irrigation efficiency.

When backwashing, the water flow direction is "bottom-up" for filtration. After the filtration is completed, there will be certain impurities such as sediment at the bottom of the filter. When the impurities accumulate to a certain extent, it will affect the normal operation of the filter. , which also affects the normal working time of the filter; in addition, the tank body of some filters occupies a large area, and the space utilization rate is not high.
