Description
Technical field
It the utility model is related to pulp technology for making paper, and in particular to paper making pulp sand removing machine.
Background technology
One of the four inventions in China of papermaking technology system, with advances in technology, papermaking are become by the production of manual workshop form
Into automatic production line production, production efficiency is substantially increased.Prior art slurrying mainly has two kinds, and one kind is former material system
Slurry, one kind is waste paper pulp-making.The former expends the natural resources such as a large amount of timber；The latter can not only reclaim waste and old paper as papermaking
Raw material, more it is that natural resources can be saved.The advantage of the latter is simple process, especially caused industrial waste, wastewater flow rate
It is less and relatively clean, deal with and be relatively easy to, the pollution to environment is also small.But because the channel for reclaiming raw material is answered
Miscellaneous, usually containing many silt particles and impurity, papermaking can not be used directly to, it is necessary to carry out desanding, impurity elimination processing by preparing slurrying.
In order to remove silt impurity contained in paper pulp, Chinese Publication No. CN203200586U utility model patent is public
A kind of regenerated papermaking slurry efficient desanding and enrichment facility, including Swirling flow sand-removing cylinder, mozzle, feed pipe, discharge nozzle have been driven, it is described
Swirling flow sand-removing cylinder bottom set sand export, described Swirling flow sand-removing cylinder top by feed coil connect feed pipe, it is described
Mozzle is set to connect discharge nozzle, described discharge nozzle connection slurry distribution pipe, described slurry at Swirling flow sand-removing cylinder upper opening
Expect to set enrichment facility below distribution pipe, both seats, this device is starched using pump and pressed by multiple Swirling flow sand-removing cylinders of connecting
Heavy sand in slurry and light fiber separation are solved the problems, such as efficient desanding by power and cyclonic action.
But said apparatus existing defects：Multiple Swirling flow sand-removing cylinders of connecting carry out multistage desanding and use equipment too many, take up an area empty
Between it is big, energy resource consumption is big, and desanding effect is not known, and when containing Sha Shaoshi in paper pulp, is wasted very much using multiple Swirling flow sand-removing cylinders,
