The present invention is not only easy to manufacture due to its simple structure, but also can be installed in a conventional corrugating plant, so that high-purity rice bran can be separated at the same time.

The apparatus for sorting high-purity rice bran according to the present invention comprises: a feed hopper (10) for feeding rice bran containing rice bran, rice husk, foreign matter and rice bran; A pure water uncollected portion 21 provided at a lower portion of the supply hopper and having an untreated through hole formed therein and a mixture sorting portion 22 having a relatively large mixed through hole formed therein; A wind blowing fan 30f is provided at one side of the sieve and blows down a relatively low specific gravity of the mixture of rice, rice, and rice gruel which has passed through the mixture sorting unit 20 by the wind supplied from the blowing fan A sorting chamber (30) for separating; A pure water untreated tank 40 for storing only pure untreated water having passed through the pure untreated water selection part 21; A mixed untreated tank (50) containing a foreign substance separated from the mixture; And a dust collecting duct 60 installed at an outlet of the sorting chamber 30 for sucking mixed raw water blown by the blowing fan and sending the mixed raw water to the mixed differential tank.

The supply hopper 10 has a cylindrical shape and a rotary valve 10r is provided at a lower end thereof to control the discharge of the rice bran stored therein.

The untreated gutters (20) are composed of a mesh body having fine through holes formed therein as means for separating impurities except for the boreholes and the boreholes. The borehole sorting portion (21) in which relatively small boreholes A mixture sorting portion 22 formed at the lower portion of the outlet of the supply hopper 10 and formed with a relatively large particle mixture or through-hole through which the rice leaves is formed is formed at the discharge end.

As shown in FIGS. 1 to 4, the sieve 20 having the through-holes formed therein has a high end toward the supply hopper 10 and is installed in a state where the other end is low, and is contained in the rice bran supplied through the supply hopper 10 After the raw corpuscle is firstly separated from the raw corn sorting section 21, the foreign matters including the raw corn or the rice passed through the corn gauge sorting section 21 are separated in the mixture sorting section 22, The foreign matter of particles larger than the formed through hole was discharged to the end.

As shown in the drawing, the lower portion of the filter net 20 is provided with a discharge port (not shown) having a shape of a supermarket for the purpose of collecting and separating the separated pieces in the untreated water separating portion 21 and the mixture sorting portion 22, A pure water discharge mouth hopper 21h and a mixture discharge hopper 22h each having an upper light-tight narrowing shape are provided at the lower portions of the discharge ports 20a and 20b, respectively. So that the rice bran discharged from the discharge ports 20a and 20b and the rice grain can be moved to the hoppers 21h and 22h.

A discharge pipe or a hose (hereinafter also referred to as a hose) is connected to the lower end of the rice gut discharge hopper 21h provided to correspond to the rice gut sorting section 21 of the hoppers 21h and 22h, And is connected to the untreated tank 40, and the above-mentioned sorting chamber 30 is provided below the mixture discharge hopper 22h.

The sorting chamber 30 is a means for sorting the raw gravel remaining in the foreign matter including the rice gruel or the rice gruel which has passed through the gruel sorting part 21 of the filter net 20 and is provided with a blowing fan 30f on one side, And a dust collecting duct (60) for blowing air into the inside of the yarn and for collecting the raw water that is blown by the wind on the other side.

Since the rice bran is the smallest in the grain size among the foreign materials including the rice bran, rice gruel and rice bran supplied to the sorting chamber 30 and is light in weight in order of light weight, rice gruel and rice bran, the rice bran reaches the entrance of the dust collecting duct 60 The rice husk is separated from the middle portion of the rice husk, and the rice husk falls off from the position adjacent to the blower. Therefore, in the lower portion of the sorting chamber 30 from the blowing fan, A collecting hopper 31, a rice ball collecting hopper 32 and a rice gut harvesting hopper 33 are disposed in this order.

The rice storage compartments 31t and the rice storage compartments 32t are installed under the hopper collecting hopper 31 and the rice collecting hopper 32 so that the rice husks and rice husks collected by the hoppers 31 and 32 can be stored immediately , And the raw rice gob collected by the rice gob collecting hopper (33) is blown off by the dust collecting fan (33f) to be transferred to the mixed raw gauze tank (50). The reason for this is that since the rice husk and the rice husk are relatively heavy, the capacity of the blower needs to be increased in order to blow using the blower fan.

The raw rice gob collected by the rice gob collecting hopper 33 has a relatively low quality because it contains a relatively large amount of foreign substances than the rice goblets selected in the raw goblet sorting section 21 of the filter net 20. The raw rice gob collected by the rice goblet collecting hopper 33 is stored in the mixed raw gravel tank 50 without being stored in the pure raw goblet tank 40.

As described above, the sieve 20 constituting the high-purity raw-fiber sorting apparatus constructed as described above can sort the foreign materials except the raw materials and the irregularities even if it is inclined only to one side as described above. However, Accordingly, the through hole is also small, so that the through hole can easily be clogged. Accordingly, the screen 20 can be adjusted in tilt and vibrated.

3, the screen 20 includes a net 201 supported by a net fixing frame 202 and having a plurality of through holes formed therein, And a tilting frame (203) hinged to the support base (204) and provided at the other end with tilt adjusting means (24) to adjust the inclination of the network retention frame.

The inclination adjusting means 24 may be a means for increasing or decreasing the inclination of the screen 20 to change the inclination of the screen as shown in FIG.

As shown in FIG. 3, the tilt adjusting means 24 may be installed in the mesh fixing frame 202 and the rotating frame 203, And a nut 24n provided between the bolt and a distance between the two bolts depending on the rotating direction. Of course, it can be constituted by a hydraulic cylinder or other driving means, but in order to simplify the structure, it is constituted by bolts and nuts as described above.

Further, the vibration motor 23 is further provided to shake the filter net 20 to easily discharge the raw water and foreign matter into the through hole.

The vibrating motor 23 can be installed at any position as long as it can vibrate the filter net. However, when the vibration of the filter net is transmitted to other devices or components, not only a lot of noise occurs but also they can be easily aged. . Accordingly, the vibration motor 23 is installed on one side of the mesh fixing frame 202, and vibration of the vibration motor is transmitted between the mesh fixing frame 202 and the rotation frame 203 through the rotation frame (20s) for preventing the shock absorber (20).

The buffering means 20s may also be various ones, but it is preferable to use a spring having a simple structure and easy to manufacture.
