Papermaking wastewater filtering device

Abstract

The papermaking wastewater filtering device comprises a protective shell, one side of the bottom of the protective shell is communicated with a drainage pipe, a plurality of groups of vertical water guide pipes are arranged in the protective shell, the upper ends of the water guide pipes penetrate through the protective shell, a partition plate is arranged on the inner side of the protective shell, and the water guide pipes penetrate through the partition plate. The side face, located below the partition plate, of the water guide pipe is provided with a drainage hole, the side face of the water guide pipe is provided with a slag discharging opening located above the partition plate, the inner side of the water guide pipe is slidably connected with a filter plate, the filter plate is provided with vertical filter holes, the lower portion of the inner side of the water guide pipe is fixedly connected with a support, and the upper portion of the support is connected with a spring. And the upper end of the spring is connected with a piston plate. When the filter plate is blocked, the filter plate can be automatically dredged, meanwhile, dredged impurities can be discharged through the slag discharging pipe, and after the impurities are discharged, the filter plate can automatically ascend, so that papermaking wastewater is continuously filtered.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of waste water in papermaking enterprises, and in particular relates to a filter device for papermaking waste water. Background technique [0002] During the production and manufacturing process of papermaking enterprises, a large amount of wastewater will be generated. Direct discharge of such wastewater into the environment will cause great pollution to the local environment. For the purification of papermaking wastewater, filtration is an important link. However, at present, in the papermaking When the wastewater is filtered, the filter equipment is easy to be blocked quickly, and it is difficult to clean up after the blockage, which directly affects the purification efficiency of the wastewater. [0003] It should also be pointed out that the current most common dismantling and cleaning methods are prone to untimely cleaning, which further affects the purification efficiency ...

[0002] During the production and manufacturing process of papermaking enterprises, a large amount of wastewater will be generated. Direct discharge of such wastewater into the environment will cause great pollution to the local environment. For the purification of papermaking wastewater, filtration is an important link. However, at present, in the papermaking When the wastewater is filtered, the filter equipment is easy to be blocked quickly, and it is difficult to clean up after the blockage, which directly affects the purification efficiency of the wastewater

[0003] It should also be pointed out that the current most common disassembly and cleaning method is prone to untimely cleaning, which further affects the purification efficiency of wastewater. Therefore, a wastewater filter device that can effectively reduce clogging is needed
