Description
Technical Field
The invention belongs to the technical field of particle separation, and particularly relates to a regenerated fiber particle separation device for fiber board trimming materials.
Background
The fiber board is an artificial board which is made from tree branches, wood processing waste materials and the like as raw materials by chipping, steaming and hot grinding to obtain fibers, and then sizing, drying, paving, hot pressing, cooling, edge cutting and sanding. At present, the fiber board is widely applied to the production fields of ships, vehicles, airplanes, buildings, furniture and the like as an important material for national economy construction. In the production process of the fiberboard, the blank plate is subjected to edge cutting treatment, so that a large amount of fiberboard edge cutting materials are necessarily generated. It is estimated that the trim produced in the annual fiberboard production accounts for about 7.5% of the finished board production.
In order to save wood resources and reduce waste, most of fiberboard manufacturers recover, crush and recycle fiberboard trimming materials. Because fiber particles which can not be completely decomposed partially exist in the process of crushing, decomposing and regenerating fibers, the particles enter a fiber bin along with regenerated fibers to be used as raw materials of the fiber board. Due to the existence of the fiber particles, local spots and fuzzing phenomena are generated on the surface of the fiber board product, the phenomena not only influence the apparent quality of the fiber board, but also generate local color differences when a downstream enterprise furniture factory colors and sprays paint on the furniture surface, and directly influence the appearance quality of the furniture surface.
Therefore, an efficient and practical fiber board trimming material regenerated fiber particle separating device is needed, which is used for separating out fiber particles in the fiber board trimming material regenerated fibers and improving the board surface quality of the fiber board.

Because the fiber particle separating chamber adopts a semi-cylindrical design, fibers and fiber particles entering the fiber particle separating chamber move circularly along with the airflow. From physics, it is known that: the object moving circularly will obtain centrifugal inertial force F d 。
F d =mv 2 /R
Wherein: m is the mass of the object; v is the speed of movement of the object; r is the radius of the circumference.
It can be seen that when v and R are fixed, a larger mass m will achieve a larger centrifugal inertial force. Due to mass m of fibre particles Particles Mass m greater than acceptable fiber Fiber So that the fiber particles acquire a centrifugal inertial force F greater than that of the acceptable fibers d And is thrown out and falls into a fiber particle collecting tank to be separated.
Under the combined action of the two factors, fiber particles can be separated from qualified fibers, and meanwhile, in a fiber particle separation chamber, the qualified fibers are carried by air flow to enter a qualified fiber conveying pipeline through a fiber rear channel and then are sent to a separator for recycling into a fiber storage bin through a conveying fan a.
