Papermaking wastewater filter tank

Abstract

The invention discloses a papermaking wastewater filter tank which comprises a protective shell, the bottom of the protective shell is connected with supporting legs, the top of the protective shell is communicated with a water inlet valve, the inner side of the protective shell is provided with a horizontal transverse plate, and the transverse plate divides the inner side of the protective shell into a water inlet cavity and a filter cavity from top to bottom; and a plurality of groups of vertically-through water guide pipes are mounted on the transverse plate. The sealing plate drives the cleaning ring to quickly move downwards, the cleaning ring can clean the side wall of the water guide pipe and the filtering holes after moving downwards, so that the problem that the filtering holes are blocked is solved, and due to the fact that the sealing plate moves downwards, cleaned dirt can move downwards along with waste water, and after the sealing plate passes through the lower end of the water guide pipe, the sealing plate is blocked. Wastewater and dirt are discharged through the lower end of the water guide pipe and discharged through the waste residue pipe.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of wastewater in papermaking enterprises, and in particular relates to a papermaking wastewater filter tank. Background technique [0002] The current papermaking enterprises will produce a large amount of wastewater in the production and manufacturing process. In order to avoid the pollution of the current environment by the papermaking wastewater, it is necessary to effectively treat the papermaking wastewater. The filtration work can quickly remove the high-level dirt and part of the suspended matter in the wastewater, but At present, when filtering papermaking wastewater, the filter equipment is easily blocked quickly. In order to ensure the filtering effect, the filter equipment needs to be cleaned or replaced frequently, which not only costs a lot, but also directly affects the purification efficiency of wastewater. For this reason, a device that can automatically clean the...

[0002] The current papermaking enterprises will produce a large amount of wastewater in the production and manufacturing process. In order to avoid the pollution of the papermaking wastewater to the current environment, it is necessary to effectively treat the papermaking wastewater. The filtration work can quickly remove high-level dirt and some suspended solids in the wastewater, but At present, when filtering papermaking wastewater, the filter equipment is easy to be blocked quickly. In order to ensure the filtering effect, it is often necessary to clean or replace the filter equipment frequently, which not only costs a lot, but also directly affects the purification efficiency of wastewater.
