Description

Design wood chip sieving mechanism

Technical Field

The utility model belongs to the technical field of shaving board production facility, concretely relates to design wood chip sieving mechanism.

Background

When the shaving board is produced, the wood is required to be crushed into raw materials with certain sizes for production and standby. In the production of particle boards, the particle boards are produced from different raw materials, i.e., the crushed wood is classified according to the intended use during the production of the particle boards. At present, the classification of the wood chips is mostly carried out through manual classification or screening through a material sieve, but the principle of the screening device is that the material classification is realized through a screen or a material roller, the classification is carried out according to the size of the material, and therefore, during the classification, the material can be doped with granular impurities such as bricks, stones, metal scrapped parts and other foreign matters. The removal of blocky foreign matters in the raw materials of the shaving board cannot be realized through the current technical means alone.

Aiming at the above technical problems encountered in the current field of particle board production, what the skilled person in the art needs to solve is: the existing wood chip screening equipment is improved, a device capable of realizing classification by adopting weight is designed, and the wood chip screening equipment is combined with the equipment in the prior art, so that the wood chips can be finely classified in the two directions of volume and weight.

Disclosure of Invention

For overcoming prior art not enough, the utility model provides a design wood chip sieving mechanism, its horizontal transport through conveyor realization material adopts the air current to realize blowing of material in transportation process, realizes multistage classification according to different weight.

In order to achieve the technical purpose, the utility model adopts the following scheme: a sizing wood chip screening device comprises a material auger, wherein the material auger is connected with a classifying bin body, a directional fan is arranged corresponding to the classifying bin body, the directional fan supplies air to the end part of a conveying belt, a material shunting baffle is arranged at one side corresponding to the conveying belt, and at least two blanking ports are arranged at the bottom surface of the classifying bin body corresponding to the material shunting baffle; the classification bin body is also internally provided with a light material shunting port. The light material shunting port is connected with the cyclone separator, and the cyclone separator is provided with a light material outlet and a qualified material outlet.

The material diversion baffle is of an adjustable baffle combined structure and is in a three-fork structure, the three baffles are connected through a middle fixing shaft, the middle fixing shaft is fixed on the front side wall and the rear side wall of the classification bin body, and an adjusting device used for rotating the middle fixing shaft is arranged at the end part of the middle fixing shaft.

The light material flow distribution port is arranged on the top surface or the top corner of the classification bin body and is opposite to the directional fan.

The beneficial effects of the utility model are that: the utility model discloses an above structure setting, it carries out the selection by winnowing classification through directional fan with the material on the conveyer belt, carries out tertiary separation once to the material, to heavier or the relatively heavier material back of classifying, the relatively lighter material gets into to the light material reposition of redundant personnel after-feeding once more and selects separately to external equipment once more. Through this kind of structure setting, this device realizes through the mode that wind-force blows that the material is selected separately, can collect the rejection in unison with adulterated stone, fragment of brick, metal waste in the wood chip, has realized classifying according to weight of material according to the weight ratio difference simultaneously, is the design wood chip sieving mechanism of an ideal.
