Description

Heavy slag pipe structure of light slag separator

Technical Field

The utility model belongs to pressurized screen slurrying screening system especially involves a heavy slag pipe structure of light slag separator.

Background

At present, a large amount of waste paper is adopted for pulping in China, the content of large-particle impurities in raw materials is extremely high, the abrasion to pulping equipment is increased, and the service life of the equipment is shortened. Therefore, impurities are separated from the paper pulp as early as possible, and the method plays an important role in improving the service life of equipment, reducing the installed power, ensuring the quality of finished paper and other key indexes. The light residue separator is usually used for a tail screen of a coarse screening section, can effectively remove impurities in paper pulp, reduces the loss of subsequent equipment, and simultaneously reduces the fiber loss in the residue removal process. However, the heavy slag pipe of the common light slag separator in the market is in the horizontal direction, as shown in fig. 1, the heavy slag pipe is not beneficial to the collection of heavy impurities, so that the abrasion of the cylinder wall of the cylinder body can be accelerated.

As a preferred scheme of the utility model, the heavy slag pipe is provided with a heavy slag inlet, a heavy slag outlet and a slag discharging cavity, and the area of the end surface of the heavy slag inlet is larger than that of the end surface of the heavy slag outlet; heavy sediment import and heavy sediment export are through arranging the smooth transition connection of sediment chamber, can effectively discharge the heavy impurity that catches to because the decurrent structure that sets up of slope makes the discharge that heavy impurity can be faster under the effect of dead weight and barrel internal heavy impurity extruded, and the single of heavy sediment import advances the current increase relatively, has improved the ability of heavy sediment pipe seizure heavy impurity, has reduced the wearing and tearing that heavy impurity emission did not in time cause head and section of thick bamboo wall, increase of service life.

As the utility model discloses an optimal scheme, heavy sediment import is square import, and square import has increased the size of entering the sediment mouth, has improved the ability of heavy sediment pipe seizure heavy impurity, and the cross-section of heavy sediment export is circular export, and circular export has avoided heavy impurity to pile up the lateral wall.

As an optimized scheme of the utility model, export outer wall department at heavy sediment and be equipped with the flange, the setting of flange is for the outside auxiliary structure of better connection, carries out further processing to heavy impurity.

The utility model discloses be revised as the vertical downward structure of contained angle with the head with the setting of head tangent line level with the heavy sediment pipe of tradition, make the discharge that heavy impurity can be faster under the effect of dead weight and the cylinder internal heavy impurity extrusion, and heavy sediment import design is square in addition, increased the size of entering the cinder notch, improved the ability that heavy sediment pipe catches heavy impurity, it is circular to enter the design of sediment export, circular export has avoided heavy impurity to pile up the lateral wall, wholly reduced the wearing and tearing that heavy impurity emission did not in time cause head and cylinder wall, increase of service life.
