Description
Technical Field
The utility model belongs to the technical field of the scummer equipment, concretely relates to compound multi-functional scummer.
Background
The rotary pipe type slag remover is commonly used for pulp slag removing operation in the paper making industry, and the quality of the prepared paper can be ensured only by removing impurities in the paper pulp after the paper is crushed and pulped because the existing paper making technology is mostly based on recycling of waste paper products and the recycled waste paper has more impurity particles.
The paper pulp edulcoration slagging-off uses spiral-flow type dross removal mechanism 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 traditional slag remover has the problems that the treatment capacity is small in unit time, the inner wall of the cyclone slag removing device used for a long time is seriously abraded, and the like, so that the service life of the device is prolonged, the part is designed into a split ceramic tube, and the whole device is formed by connecting multiple tubes, so that the part seriously eroded 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 designs the device, and connects a plurality of deslagging and impurity-reducing devices in parallel to simultaneously carry out impurity-removing operation, so that the efficiency of the pulp raw stock purification operation can be effectively improved; the device is integrated with all the split parts through the stable sealing connection of the sealing connection part, and is convenient to disassemble and replace, durable and corrosion-resistant.
