No-maintenance full-automatic filter

Abstract

The invention provides a maintenance-free completely automatic filter machine, consisting of at least two groups of filter units; each group of filter units comprises a plurality of filter cores which are arranged inside the sealed shell of the filter machine; the water inlet pipeline of the filter machine is provided with a water inlet pipeline pressure divider; each formed branch pipe is connected with the internal hole at the lower end of each filter core corresponding to the filter unit; each branch pipe is provided with an electronic valve; a tailing outlet is arranged below each group of filter units; the tailing outlet is connected with the internal hole at the lower end of each filter core of the filter unit; and the tailing outlet (10) is provided with an electronic valve. The filter machine breaks through the shortage of the connection type of the existing filter core of the filter machine, achieves the object of limitless irregular arrangement of the filter cores, can achieve the backwashing function by the self-pressure difference, completes the backwashing function without effecting the normal do-work process, creates the precondition for the continuous operation of the filter machine, and provides solid foundation for fine filtration of large-scale engineering.

Description

technical field [0001] The invention relates to sewage treatment equipment in the field of environmental protection technology, in particular to a filter, which realizes the infinite irregular arrangement of filter cores, uses its own pressure difference to realize the recoil function, and creates a premise for the continuous operation of the filter condition. Background technique [0002] Obtaining clean water has become the most important factor restricting economic development and improving people's quality of life. Under the current conditions of severe pollution and shortage of water resources, polluted water needs to be treated so that it can continue to be used. At present, using a filter with a filter element to filter the water source using physical methods is still the main means of obtaining clean water. In order to achieve a better filtering effect, the existing filter generally adopts a method of connecting multiple filter elements in series to realize multi-st...

AI Technical Summary

Problems solved by technology

The equipment covers a relatively large area and the amount of engineering is huge. In the case of very high land costs in big cities, the construction cost and operating cost remain high, which restricts the use of this technology

For ultra-fine particles, the process has to use chemical methods to flocculate before filtering, resulting in secondary pollution of residual substances after chemical flocculation
