Example Embodiment

[0029] The present invention will be further described below in conjunction with the drawings.

[0030] Such as Figure 1 to 6 The shown pickling waste liquid residue sedimentation tank includes a filter tank 4, which is provided with a liquid inlet 5 through which the pickling waste liquid passes and a waste discharge port 6 through which the filtered clear liquid is discharged. The filter tank 4 includes The side wall and the bottom wall, the bottom wall are arranged obliquely, wherein the purpose of the inclined bottom wall is to realize the natural flow of the waste liquid from the liquid inlet to the waste liquid outlet. A filter screen assembly 1 is arranged in the filter tank 4, and a slide groove 40 is provided on the side wall of the filter tank 4, and the slide groove 40 is vertically arranged.

[0031] Such as Figure 2 to Figure 4 As shown, the filter screen assembly includes a filter plate 11 and a waste collecting bucket assembly 12.

[0032] Such as Figure 4 As show...

Abstract

The invention discloses a filter-screen assembly and an acid cleaning waste liquor-residue settling pond. The acid cleaning waste liquor-residue settling pond comprises the filter-screen assembly, the filter-screen assembly comprises a filtering plate and a waste-collection hopper assembly, the filtering plate comprises a main filter screen and a slide block, the edge of the main filter screen is fixed to the slide block, and the waste-collection hopper assembly is located at the bottom of the slide block; the waste-collection hopper assembly comprises a hopper bottom wall, the hopper bottom wall is fixed to the bottom of the slide block, a water channel is arranged in the hopper bottom wall and is located at the junction of the hopper bottom wall and the main filter screen, the waste-collection hopper assembly is provided with an opening which faces a waste liquor inflow inlet, and the opening is formed by the main filter screen and the hopper bottom wall. The waste liquor is filtered through the filter-screen assembly, waste residues are quickly separated from the waste liquor, the time is saved, the separated waste residues are centralizedly stored in the waste-collection hopper, workers can quickly take out the waste residues simply through extraction of the filter-screen assembly, the waste residues are not in contact with the bottom of the settling pond, the situation that the waste residues are attached to the bottom of the settling pond is avoided, and the cleaning frequency is lowered.

Description

technical field [0001] The invention relates to a waste liquid treatment device, in particular to a filter screen assembly and a pickling waste liquid slag settling tank for filtering and treating solid waste residue inside the pickling waste liquid. Background technique [0002] Pickling is a method of using an acid solution to remove scale and rust on the steel surface, and is a method of cleaning the metal surface. The waste liquid after pickling contains soluble solutes and some waste residues that fall after pickling. It is necessary to use a specific pickling waste liquid slag sedimentation tank to precipitate the insoluble solid waste inside the pickling waste liquid. And filtered and picked up, then the pickling waste liquid is processed so that it can meet the discharge standard. [0003] Regarding the filtration of solid waste residues, the current method used is: put the pickling waste liquid containing waste residues into the sedimentation tank, discharge the wa...
