Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] Embodiments of the invention include:

[0019] attached figure 1 It shows a beam-splitting slag removal device, which includes a large slurry feed pipe 1 and several light slag removers 2. The light slag removers 2 are hollow and inverted cones whose inner diameter gradually decreases from top to bottom, and the slurry feed is large. The tube 1 is a sealed cylinder with an inner cavity. The large slurry feeding pipe 1 is provided with a slurry inlet 3 connected to the inner cavity of the large slurry feeding ...

Abstract

The invention relates to a splitting and deslagging device which comprises a large pulp inlet pipe and a plurality of light deslaggers, wherein the light deslaggers are in hollow inverted taper shapes; inner diameters of the light deslaggers are reduced gradually from the top down; a pulp inlet is formed in the large pulp inlet pipe; a plurality of pulp inlet heads are arranged in the large pulp inlet pipe; pulp inlet holes are formed in the pulp inlet heads; the pulp inlet heads are tangentially connected with the pulp inlet holes; the bottoms of the pulp inlet heads penetrate through the large pulp inlet pipe and are communicated with the light deslaggers; good pulp pipes are arranged on the tops of the pulp inlet heads; and pulp slag outlets are formed at the bottom ends of the light deslaggers. The pulp inlet holes with smaller semidiameters are formed in the pulp inlet heads; when pulp is fed tangentially during pulp feeding, due to a sudden change of diameters of pulp feeding routes, rotation pressure is increased to form inner vortexes; a deslagging effect of the pulp is improved; and the purity of the pulp is ensured.

Description

technical field [0001] The invention relates to the technical field of paper manufacturing equipment, in particular to a beam splitting and slag removing device. Background technique [0002] With the improvement of people's living standards, people's requirements for commodity packaging are getting higher and higher. Now people not only require strong packaging, but also print relevant information of various contents on the outer packaging, as well as some related exquisite pictures, paper The high cleanliness of the surface often leads to better printing and appearance effects, so clean surface paper is the current key research topic. [0003] In the traditional pulp treatment process, light cleaners are often used to remove lighter impurities in the pulp. The small diameter and high pulp feeding pressure are often more conducive to the removal of light impurities. The traditional lightweight slag remover has a single structure, occupies a large area, consumes a lot of en...
