Vertical flow type micro-filter and working method thereof

Abstract

The invention discloses a vertical flow type micro-filter and a working method thereof.The vertical flow type micro-filter comprises a micro-filter body, a vertical flow separation bin is arranged on the lower portion of the micro-filter body, a drain outlet is formed in the portion, located below the vertical flow separation bin, of the lower portion of the micro-filter body, and the drain outlet is externally connected with a drain pipe; a brush reciprocating motion mechanism is arranged at the position, located above the vertical flow separation bin, in the microfiltration machine body, a filter screen is arranged at the position, located above the brush reciprocating motion mechanism, in the microfiltration machine body, and a water outlet pipe is arranged on the side portion of the upper portion of the microfiltration machine body; a water level sensor and a pollution discharge water level sensor which are distributed up and down are arranged at the side part of the upper part of the microfiltration machine body, and a water inlet pipe is arranged at the position, close to the vertical flow separation bin, of the side part of the lower part of the microfiltration machine body. By combining the advantages of a vertical flow type separator and filtering of the filter screen, large-particle and large-specific-gravity garbage is firstly removed, then the garbage which can be intercepted by the filter screen is removed, and the garbage is backflushed and discharged by utilizing pressure formed by the water level of the garbage.

Description

technical field [0001] The invention relates to a vertical flow microfilter and a working method thereof, belonging to the technical field of filtering equipment design. Background technique [0002] The current general filtration mode is to separate the garbage and water through the filter, or to make the garbage settle through the difference in the weight and buoyancy of the garbage, thereby separating the water and the garbage. The advantage of the filter is high filtration efficiency, but the disadvantage is that a filter cannot To deal with the garbage of various filter diameters, the rotary drum microfilter uses large particles of garbage to repeatedly roll in the circular filter screen until the volume becomes smaller and settles, or decomposes to a point where the weight of the particles is less than the sum of the buoyancy and the adhesion of the filter screen. can be brought to the position where it was recoiled. [0003] The existing filtration equipment has the ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the technical defects of the existing technology, solve the technical problems of the existing filter equipment with a small filter particle size range and low filter efficiency, and propose a vertical flow microfilter. The vertical flow separation principle uses the filter screen and the brush to filter the garbage within the mesh size of the filter screen and discharge it from the whole system. Since there is no limit to the filter particle size, the filter effect is higher than that of the traditional filter mode.
