Description

Waste paper slurry screening and collecting device

Technical Field

The utility model belongs to the technical field of pulp collection, and particularly relates to a waste paper pulp screening and collecting device.

Background

Along with the release of the national waste forbidden orders in recent years, the solid waste is forbidden to enter the country comprehensively, which means that the waste paper serving as an important component of the solid waste can not be imported directly, and raw materials of the papermaking industry in China are mainly pulp and waste paper, so that the import quantity is large. In order to ensure stable supply of raw material resources, the waste paper which is originally solid waste is produced into regenerated fiber pulp in overseas pulp factories by a part of domestic paper factories, and then imported into China in the forms of flat plates, reels, wet pulp and the like.

For the detection standard of imported regenerated fiber pulp, the national standard of regenerated pulp specifies that the regenerated fiber pulp needs to be detected, and the regenerated fiber pulp needs to be screened to reach the detection standard, namely small non-fiber sundries are screened out, the pulp screened by a screening machine needs to be collected, meanwhile, the screened pulp needs to be removed along with a large amount of water during discharge, water is usually discharged by a pulp bag with smaller mesh and permeable, and the fiber pulp after being discharged through a through hole of the pulp bag remains in the pulp bag to be recovered.

The existing collection mode is that a worker holds a slurry discharging pipe by hand and inserts the slurry discharging pipe into a slurry bag for manual collection, however, slurry recovery is a continuous process, the conventional use time is at least 30 min, the water consumption is 10L/min, fiber slurry continuously forms wet slurry cakes after being discharged, water filtering of the slurry bag is blocked, two problems are caused by untimely water filtering, firstly, the worker can continue to recover fiber slurry after waiting for accumulated water to be discharged, and the collection process is complex; secondly, the untimely drainage can lead to the overflow of the fiber pulp out of the pulp discharging bag, so that a worker is required to watch at one side, and manpower is lost.

For the problems in the related art, no effective solution has been proposed at present.
