Automatic door discharge apparatus opens and shuts

Technical Field

The utility model belongs to the technical field of machinery, a automatic discharge apparatus that opens and shuts is related to, especially a discharge apparatus that opens and shuts automatically that is used for paper pulp to arrange sediment.

Background

The paper industry typically produces paper by obtaining virgin pulp through a series of pulp processes. In the pulping process, a deslagging system is an indispensable link for purifying paper pulp, pulp slag is generally removed by a deslagging device and is emptied in time, and deslagging is usually carried out for multiple times to obtain final paper pulp.

Pulp deslagging is the process of removing impurities from a fibrous suspension, i.e., separating various impurities from the pulp that are entrained in the pulp. Impurities contained in the slag need to be removed in time, otherwise the impurities are easy to accumulate at an outlet and are easy to block, and subsequent slag materials are not settled in the slag collector and are involved in good pulp instead, so that the slag discharging effect is influenced, and the equipment is abraded.

In the case of relatively high requirements for the formed paper quality, the pulp needs to be further screened in addition to the slag discharge, impurities are separated in a targeted manner based on the difference between the shape, size and specific gravity of the impurities and the fibers, and the fiber loss in the treatment process is reduced as much as possible.

However, in the existing pulp pulping process, the tail part is subjected to slag discharge and then is directly discharged on the ground or in a cement cofferdam in a direct discharging and non-collecting mode. The dirty and messy site is poor, the sewage can easily flow in, and the requirements of environmental protection and site standardization are not favorable.

In addition, the existing slag discharging mode easily causes continuous emptying of slag slurry, and fiber loss is caused; meanwhile, the system pressure fluctuates due to the overlarge slag discharge pressure.

To sum up, for solving the structural not enough of current paper pulp row sediment equipment, the utility model designs a rational in infrastructure, arrange effectual automatic opening and shutting discharge apparatus of sediment.
