Abstract

The utility model relates to a device for recovering fiber from waste water, which is entirely arranged on a frame. The utility model comprises a set of or more than a set of filter net driving devices. Each set of filter net driving devices is provided with a filter net and two or more than two rollers. The corresponding positions of the rollers on the top end of each set are provided with overflowing slots, the lower parts of the filtering segments of a filter net are respectively provided with a water slot, the bottom parts of the rollers at the lower end of the filter segments of the filter net are respectively provided with a fiber scraper and a fiber slurry slot. A motor, a reducer, a belt and the rollers compose an integral driving mechanism. The device has the advantages of simple structure, rational structure, easy continuous operation, investment saving and small energy consumption, and the recovery rate of fber can reach more than 95 percents. The utility model both changes waste into a useful material and reach the effect of environment protection.

Description

Device for recovering fibre from waste water

This device belongs to a kind of fiber recovery machinery, is mainly used in the recovery of fiber in the paper waste.

The waste water that discharges in the paper industry is in order to reach environmental requirement, to adopt the air supporting method or the precipitation method to handle mostly at present.Its shortcoming is that the fiber that reclaims contains harmful substances such as higher shallow lake material, sticking impurity, ash, can not directly be used further to paper production, and power consumption, time-consuming.The employing cylinder recovery machine that also has reclaims the fiber in the paper waste, and this recovery machine is same to be existed above not enoughly, and equipment investment is big, and removal process can not continued operation, and the fiber reusability of recovery is poor.

The purpose that designs this device is to overcome the deficiencies in the prior art, provides a kind of and realizes the recovery of fiber by the filter screen transmission, and be easy to continued operation, can be widely used in the device of fiber recovery in the paper waste.

The designer is a technical scheme of conceiving and finish this device like this: have an overall framework, by a group or more filter screen---rotor drive is installed on the framework, every group has filter screen and two or more cylinder, relevant position at the cylinder on every group of top is provided with overflow launder, the below of strainer filtering section is installed tank respectively, cylinder bottom in strainer filtering section lower end respectively is provided with fiber scraper and fiber stock tank, forms whole transmission mechanism by motor, decelerator, belt and cylinder.This device carries out work like this: be extracted into waste water outflow in first overflow launder to filter screen by water pump, driving filter screen by motor by decelerator---drum apparatus is done uniform rotation simultaneously, filtrate flows into the tank of below, fiber is attached to be stayed above the filter screen, rotation along with filter screen, the fiber of staying the surface is scraped by scraper, flows into the fiber stock tank and collects.When carrying out said process, filtrate filtered is guided in the following overflow launder for the first time, repeats as above processing procedure.

This apparatus structure is simple, reasonable, and applicability is strong, and fiber recovery can reach more than 95%, and fiber reclamation rate height, both turns waste into wealth, and reclaims a large amount of usable fibers to factory, has saved raw material, can reach the effect of environmental protection again.Except that the lift water pump of the extracting waste water of necessity, about 0.005 degree of one ton of water power consumption of every processing, energy-saving effect is remarkable.

Below the contrast accompanying drawing is elaborated to the utility model, provides the design's embodiment simultaneously.

Fig. 1 is the principle schematic of fibrous recovery unit;

Fig. 2 is the structural representation of fibrous recovery unit;

Present embodiment adopts two groups of filter screens---rotor drive, one group of top that is installed in framework 19, by cylinder 1,5,17 and filter screen 3 form, another group is installed in framework 19 bottoms, by cylinder 7,9,13 and filter screen 8 form, cylinder 1,5,17 and cylinder 7,9,13 arrange with triangle respectively is fixed on the framework 19, overflow launder 2 is installed on cylinder 1 relevant position and is divided water plate 24, overflow launder 6 and overflow plate 20 are installed in cylinder 7 relevant positions, filter screen 3,8 fillter section bottom is provided with tank 4 respectively, 10, cylinder 13,17 bottoms are respectively equipped with fiber scraper 12,16 and fiber stock tank 11,15, motor 22, decelerator 23 is installed on the vertical support frame of framework 19 bottoms, and by belt 21 and cylinder 5,9 interlocks.For preventing that filter screen from blocking, the reverse side at filter screen 3,8 adds cleaning brush 14,18 respectively, and the afterbody of cleaning brush 14,18 is connected with the edge of tank 4,10.
