A new type of mechanical pulp circular net dehydrator net cage trial production on "Yue paper"

"In recent days, a one-time trial of a new type of mechanically ground wood pulp rotary screen dryer designed and manufactured by the Hunan Yueyang Paper Group's pulp mill has been successful. It has the advantages of reasonable structure, smooth operation, uniform sizing, and obvious dewatering effect. Compared with the previous reduction of nearly 20,000 yuan, the pulp concentration after dehydration increased from 0.9% to 5% or more, fully meeting the quality requirements of mechanically ground wood pulp.

The technicians of Yuezhi Machine Shop aim at the traditional dehydrator cage made up of multiple spokes, copper plates, copper strips, copper wires, etc. The structure is complex, and the copper wire wear block and copper strip are easy to loosen and break, making maintenance difficult. , high consumption, high maintenance frequency and high cost. After extensive data collection and peer experience, the new network will change the mandrel to a hollow shaft, reduce the number of spokes, replace the copper plate, copper bar, and copper wire of the original cage with a stainless steel plate with a drilled surface. With the elimination of more expensive copper materials, each dewatering machine can save nearly 3,000 yuan, while simplifying the structure of the cage and reducing the weight by 1/3, which greatly reduces the difficulty of maintenance and cost, and the service life is also reduced. Effectively extended. The application of this new type of cage is the first time in the country. It is the ideal dewatering equipment for mechanically ground wood pulp. ""
