Circulating purification device for fertilizer waste liquid

Abstract

The invention discloses a circulating purification device for fertilizer waste liquid. The circulating purification device comprises a purifier shell; a feeding pipe is welded to the middle of the upper end of the purifier shell; a discharging pipe is welded to the middle of the bottom end of the purifier shell; a filter box is arranged in the middle of the interior of the purifier shell; an opening is formed in the upper end of the filter box; and a filter screen is installed at the opening in the bottom end of the filter box. The device has the beneficial effects that the filter box and a limiting frame are arranged, fertilizer waste residues in waste liquid are collected in the filter box after being filtered by the filter screen, and when the fertilizer waste residues need to be collected and utilized, a rotating handle of the limiting frame is rotated to unfix a fixed seat, and the fixed seat and the filter box can be pulled out to collect and utilize the waste residues; and a first inspection fan is arranged, so that when the filter screen is blocked due to excessive accumulation of the waste residues, a user can observe that the rotation of a first outer fan of the first inspection fan is obviously slowed down or stopped, and the blockage of the filter screen can be found in time.

Description

Technical field: [0001] The invention belongs to the technical field of waste material and liquid purification equipment, and in particular relates to a circular purification device for fertilizer waste liquid. Background technique: [0002] Fertilizer waste liquid is the waste liquid produced in the process of fertilizer production. Since the waste liquid contains fertilizer waste residue, it will cause environmental pollution if it is discharged into the environment, and the waste residue cannot be recycled effectively. Therefore, when discharging fertilizer waste liquid, Generally, the waste liquid is purified. [0003] Under the prior art, in an environment-friendly compound microbial fertilizer waste liquid treatment equipment with the patent number CN201720457243.7, the waste liquid is thoroughly filtered through the waste liquid treatment equipment, and impurities can be cleaned to prevent clogging, but not It is convenient to collect and utilize the fertilizer resid...
