Description

slag remover

Technical Field

The utility model relates to a papermaking equipment field, specific is a scummer.

Background

In the pulping production process, the raw materials and chemicals are mixed with particle impurities, so that the quality of the finished paper pulp or paper is directly influenced. And the damaged equipment hinders the normal production, so the pulp must be subjected to deslagging and purifying treatment to meet the requirements of product quality and normal production, and the desanding and purifying are processes of separating impurities with higher density from fibers under the action of centrifugal force by utilizing the principle of centrifugal separation according to the difference of the density between the impurities and the fibers in the pulp. The existing impurity separator for pulping and papermaking adopts the centrifugal principle to pump slurry containing impurities into a vertical and fixed conical cylinder with large upper diameter and gradually reduced lower diameter by a pump, and the gravity separation is carried out by utilizing the density and specific gravity difference of the impurities and the slurry.

Waste paper in waste paper can be roughly divided into three aspects, namely 1, waste impurities with density or relative density higher than that of water, such as metal glass blocks, broken stones and the like, or waste impurities with density lower than that of water, such as foam, plastic and the like, can be removed by a slag remover, and impurities such as sticky matters with relative density close to that of water and the like are difficult to remove by the slag remover. 2. The size range is large, up to 8 to 10 mm, down to five microns or less, and can be removed with a deslagger. 3. Deformable soft impurities such as stickies, which are deformed by force and easily pass through the screen holes or slots, but have sufficient difference in density from water and particle size within the removal range of the cleaner, can still be removed by the cleaner.

According to the difference of removing impurities, the slag remover can be divided into a forward slag remover, a reverse slag remover, a through-flow slag remover and a light and heavy slag remover.

The positive slag remover can only effectively remove waste impurities with relatively high density, such as broken stone, glass, sand grains, screws, staples and metal foils, which are common in domestic and foreign paper making and pulping production lines and are indispensable purifying equipment, when slurry enters the top of the slag remover from a feed inlet downwards at a specific angle in a tangential direction, vortex is generated, the slurry and the impurities move along the inner wall of the slag remover in a spiral line direction to a slag discharge port, the vortex of slurry flow generates centrifugal force, so that the impurities with density heavier than water are thrown to the inner wall of a cylinder body, the heavy impurities such as broken stone metal blocks and the like sink under the action of pressure difference and are discharged to the slag discharge port from a lower cone port, and the purified slurry rotates upwards along the center and is discharged from a top good slurry port.

the reverse slag remover is a purifying equipment for removing light impurities, the structure principle of which is similar to that of the forward slag remover, but the reverse slag remover is opposite to that of the forward slag remover in use, and the fibers are discharged from the bottom of the lower cone, and the light impurities are discharged from the upper central pipe, so that the impurities lighter than the fibers in the slurry, such as foam, plastic fragments, styrene, wax and other light impurities, are removed.

The through-flow type slag remover is also a light impurity slag remover and is a variant of a reverse slag remover, and the difference between the through-flow type slag remover and the reverse slag remover is that a good pulp opening is not positioned at the upper part of the slag remover but positioned at the bottom of a lower cone.

the heavy impurity slag separator is a mixed product of a forward slag separator and a reverse slag separator, the top of the slag separator is provided with two concentric good pulp pipes and a light impurity discharge pipe, heavy impurities are the same as the forward slag separator and are discharged from the bottom of the slag separator, after fibers and light impurities rise to the upper part of the slag separator from an inner vortex, the light impurities are discharged from the light impurity pipe at the center, and the good pulp is discharged from the annular space of the two concentric pipe sleeves.
