Background technology

In the process of Cereals oil plant, sorting and the removal of impurities technical process that is absolutely necessary.The Cereals oil plant is before processing or after the shelling, carry out removal of impurities or with shell skin and unhulled seed and the benevolence that has shelled or separate, to guarantee the grade quality of Cereals oil plant.Cereals oil plant removal of impurities sorting unit of the prior art is made of many single straight-line oscillation separators, so that reach the separating effect of people's expectation.The straight-line oscillation separator mainly is made of frame, sieve nest, electric activator etc.Wherein, sieve nest is a rectangular box, be provided with the lip(ped) sieve sheet in the sieve nest, sieve nest is installed on the frame by flexible member, both constitute the elasticity connection, and electric activator produces and revolves the replica vibration, removes the impurity in the Cereals oil plant, or shell skin and unhulled seed on the sieve nest are separated from each other with benevolence that has shelled or grain, realize the purpose of removal of impurities and sorting.These straight-line oscillation separators are normally in one line, horizontal positioned.For the material that last separator handled passes to next separator, and it is emitted on the correct position of next separator, also needs to connect, constitute a Cereals oil plant removal of impurities separation production line with lifting device.Subject matter that this cover Cereals oil plant removal of impurities sorting unit exists is, 1, complete equipment has tens meters long, and floor space is big.2, will each separator be coupled together with lifting device, and every separator all needs an independently frame, thereby the cost of equipment is higher, has increased the investment cost of manufacturer.3, because the production line that each separator constitutes is longer, so, be not easy to producer's operation and management.4, the energy consumption of complete equipment is higher.5, separating effect is poor, and electric activator can only produce a kind of motion, thereby the motion mode of sieve nest is single, is difficult to reach the separating effect that people require.

Summary of the invention

The technical problems to be solved in the utility model is, overcome big, the problems such as cost is high, separating effect difference of floor space that above-mentioned Cereals oil plant removal of impurities sorting unit exists, the dustpan-like sorting and impurity-removing device of a kind of compact conformation, cheap, sorting and good impurity removing effect is provided.

The utility model comprises frame, screen frame (unit), sieve nest and electric activator, electric activator is installed in the both sides of sieve nest, sieve nest is installed on the screen frame (unit) by flexible member, its special character is, eccentric shaft plane rotation device is installed between frame and screen frame (unit), eccentric shaft plane rotation device is made of power set, several eccentric stiffeners and reversing frame, described eccentric stiffener constitutes by rotating up and down axle and balance iron, rotating up and down axle is installed on the balance iron, and be connected with frame with reversing frame respectively, eccentric stiffener interconnects by reversing frame.

One end of described screen frame (unit) is hinged on the reversing frame, and the other end is connected with reversing frame by angle regulator, to regulate the angle of inclination of sieve nest.

Advantage of the present utility model is:

1, straight-line oscillation removal of impurities separator is installed on eccentric shaft plane rotation device, make sieve nest produce the vibration of both direction, be linear reciprocation oblique upper paraboloiding movement and plane gyration, the plane rotation motion helps the layering of material, it makes the benevolence that shelled or grain and the heavy seeds that occurs when removal of impurities is close to the sieve sheet, the linear reciprocation oblique upper paraboloiding movement is thrown material obliquely upward, and make the benevolence that shelled or grain nose motion to sieve nest, shell skin and unhulled seed are to the back end motion of sieve nest, two kinds of vibrations be combined with the transposition that is beneficial to material, layering, and make sieve nest produce the forms of motion that is similar to artificial dustpan sorting material, thereby the mode of the apery worker dustpan sorting material that people seek by every possible means is achieved, and good separation effect, the scope of application is wide, is suitable for the removal of impurities sorting of various Cereals oil plants.

2, complete equipment is made of straight-line oscillation removal of impurities separator and eccentric shaft plane rotation device, not only saved the space, reduced the floor space of complete equipment, and, all parts are installed on the frame, thereby greatly reduce the cost of complete equipment and use energy consumption, simultaneously, also made things convenient for operation and management.
