Description

Matched slag removal and impurity reduction device of slag remover

Technical Field

The utility model belongs to the technical field of the slag removing equipment, concretely relates to supporting slagging-off of scummer falls miscellaneous device.

Background

The spiral tube type slag separator is commonly used for pulp slag removal operation in the paper making industry, and because the existing paper making technology is mostly based on waste paper product recycling, the recovered waste paper has more impurity particles, and after the paper product is crushed and pulped, impurities in the paper pulp are removed, so that the quality of the manufactured paper product can be ensured.

The paper pulp edulcoration slagging-off uses spiral-flow type scummer more, and when the rotary motion was made in the scummer to paper pulp magma, the large granule thing in the paper pulp magma can be because of separating out from the paper pulp magma under the effect of centrifugal force. The specific principle is as follows: after the paper pulp magma that contains large granule impurity residue got into the scummer device along tangential direction, because the effect of centrifugal force separates large granule impurity from liquid, from the purpose that reaches the purified paper pulp. Because the pulp primary pulp in the slag separator needs to rotate for many circles repeatedly, and the linear speed of the pulp primary pulp rotation is also fast, the centrifugal force applied to the particles in the pulp primary pulp is much larger than the gravity. For small diameter high resistance slag separators, the internal centrifugal force can be up to 2500 times greater than gravity. For large diameter, low resistance slag separator, the centrifugal force is more than 5 times larger than gravity. The pulp raw stock generates centrifugal force in the rotating process and throws dust particles with relative density larger than that of the pulp to the wall of the device. Once the dust particles contact the wall, they lose the radial inertia force and fall down along the wall surface by the downward momentum and the downward gravity force, and enter the slag discharging mechanism. When the outward rotating liquid flow which rotates and descends reaches the bottom of the cone of the slag remover, the liquid flow is close to the center of the slag remover due to the contraction of the cone. According to the principle of constant rotation moment, the tangential speed is continuously improved, and the centrifugal force borne by impurity particles is continuously enhanced. When the pulp raw stock reaches a certain position at the lower end of the cone, the pulp raw stock turns upwards from the lower part in the middle of the slag separator in the same rotating direction and continues to flow spirally, namely the pulp raw stock is rotated inwards. The internal rotation paper pulp raw pulp is purified good pulp, and is discharged out of the device through a good liquid pipe, collected and reused.

The spiral-flow type slag remover has the advantages of simple structure, easiness in manufacturing, mounting and maintenance management and low equipment investment and operation cost, but the inner wall of the device can be corroded after long-term use, and particularly the inner wall of the cone barrel part where the spiral flow is located is seriously abraded. In order to prolong the service life of the device, the part is designed into a split type ceramic tube, and then a plurality of tubes are connected to form the whole device, so that the part with serious erosion can be replaced in time, and the loss cost is reduced. In the actual use process, the joints of the parts are more easily corroded and leaked, so that the whole device cannot be used continuously; and the connecting structure between the split bodies causes the complex disassembly and assembly steps and the inconvenient operation.

In view of this, the applicant has designed this device, can effectively assist paper pulp magma purification operation simultaneously, with each components of a whole that can function independently portion firm sealed link up as an organic whole, dismantle convenient and durable resistant erosion.
