Description

Classifying screen

Technical Field

The utility model relates to a grading plant technical field especially relates to a can clear up classifying screen of sieve mesh, make full use of waste liquid.

Background

In the process of making pulp and paper from waste paper, in order to improve the utilization rate of the waste paper, the fibers in the waste paper need to be recycled to the maximum extent, and the fibers are generally classified by a classifying screen according to the difference of the length and flexibility of the fibers and the difference of difficulty of passing through screen holes and screen gaps.

The commonly used classification system includes a primary classification and a secondary classification. The pulp can be divided into a long part and a short part through primary grading; the pulp can be divided into three parts of long, medium and short fibers by secondary classification. The classified fibers can be selected from different processing technologies to produce paper with different qualities or be applied to different parts of the surface, middle and bottom layers of the paper, so that the fibers with different qualities are fully utilized. After the classification, a large amount of impurity often remain in the sieve mesh, if not in time the clearance can influence the normal use of screen cloth, in addition, the waste liquid that produces behind the clearance sieve mesh if direct discharge can cause fibrous waste in the waste paper.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a classifying screen, which includes a box body 1 and a water storage tank 2, first water pump 3 and second water pump 4, from top to bottom sets gradually first sieve 5 and second sieve 6 in the box 1, first sieve 5 and second sieve 6 are the slope form in box 1 and place, the material of first sieve 5 and second sieve 6 is the carbon fiber, evenly lay the sieve mesh on first sieve 5 and the second sieve 6 respectively, sieve mesh aperture on the first sieve 5 is greater than sieve mesh aperture on the second sieve 6, first feed inlet 11 and second feed inlet 12 are seted up respectively to the left upper end of box 1, leakage fluid dram 13 is seted up to the left lower extreme of box 1, water inlet 14 is seted up to the upper end on the right side of box 1, first feed inlet 11, the position of second feed inlet 12 and water inlet 14 all is higher than the position of first sieve 5, the position of leakage fluid dram 13 is less than the position of second sieve 6.

Store water in the storage water tank 2, storage water tank 2 leads to water pipe and the end intercommunication of intaking of first water pump 3, set up valve 8 on the water pipe of intercommunication storage water tank 2 and first water pump 3, the water outlet end of first water pump 3 is connected water inlet manifold 7, water inlet manifold 7 passes water inlet 14 and stretches into the inside of box 1, be located and connect seven water inlet branch pipes 71 on the water inlet manifold 7 of the inside of box 1, the end of water inlet branch pipe 71 sets up stainless steel sprinkler bead 72, be equipped with water spray aperture 721 (as shown in fig. 2) on the stainless steel sprinkler bead 72.
