Description
Technical Field
The utility model relates to a gravity disc pulp scraping device for long fibers with low beating degree, and belongs to the technical field of pulp concentration.
Background
The gravity disc type thickener is to dewater by liquid level gravity to concentrate slurry. The method is widely applied in the field of pulping and papermaking due to small occupied area and large productivity.
Working principle of gravity disc type concentrator: in the working process, when the filtering fan sheet is immersed below the liquid level, the liquid level difference exists between the inside and the outside of the filtering fan sheet at the moment, and under the action of the liquid level difference, water in the slurry enters the hollow main shaft through the filter screen covered outside the filtering fan sheet and flows out through the mutually communicated cavity channels in the hollow main shaft. When the slurry coated on the filter screen rotates out of the liquid surface, the slurry loses adhesion due to disappearance of liquid level difference, and is automatically stripped under the action of gravity to overflow out of the slurry, so that the concentration purpose is achieved.
Gravity disc concentrators are conventional pulp concentrating devices, commonly used in different pulp types such as wood pulp, straw pulp, and the like. However, when straw-made machine pulp with a low beating degree of 25-30 DEG SR and a high wet weight of 9-13g is processed, the pulp is accumulated in the middle of the filter fan blades due to the problems that the pulp is not adhered to the filter fan blades and can not rotate forwards along with the filter fan blades because the beating degree is too low, the water filtering is too fast, and the pulp fluidity is poor. After a certain amount of the slurry is accumulated, the filtering fan blades are extruded and deformed to block the slurry channel, and finally the slurry is forced to stop, so that the slurry is flushed with water by manpower. The starting efficiency is affected, hidden danger of equipment damage is caused, and the working intensity of staff is increased.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
