FIG. 1 is a schematic perspective view of a soybean dust sifter of the present invention;

FIG. 2 is a schematic sectional view of the soybean dust sifter of the present invention.

Detailed Description

As shown in fig. 1 and 2, the soybean dust separator of the present invention comprises a separating screen casing 10, a hollow cavity 11 is arranged in the separating screen casing 10, an oval inner wall 12 is arranged outside the hollow cavity 11, and the oval inner wall 12 facilitates the tumbling motion of soybeans. A feed inlet 13, a fine material discharge port 14 and a coarse material discharge port 15 are respectively arranged on the screening shell 10, the feed inlet 13 is used for feeding soybeans and inputting high-pressure gas, and the feed inlet 13 adopts an air blower air supply mode to supply air and feed materials. The fine material discharge port 14 is used for discharging screened dust and bean wool, and an air draft mode is adopted at the fine material discharge port 14, so that the inside of the hollow cavity 11 is in a pressure difference state. The coarse material outlet 15 is used for discharging screened soybeans, and the soybeans are discharged from the coarse material outlet 15 by pressure difference in a natural ventilation mode. The outer pipes of the feed inlet 13, the fine material discharge port 14 and the coarse material discharge port 15 are all provided with threads 16, and the threads 16 are used for sealing connection of an exhaust pipe, a feeding pipe and an air supply pipe.

As shown in fig. 1 and 2, a disc 20 is disposed in the middle of the hollow cavity 11 in the sieving housing 10, the disc 20 is in a suspended state, the disc 20 is fixed on the elliptical inner wall 12 through a bracket 21, the disc 20 is also in a hollow state, an outlet 22 is disposed at the lower end of the disc 20, the disc outlet 22 is connected with the fine material outlet 14 and is separated from other parts of the hollow cavity 11, that is, the air suction mode of the fine material outlet 14 directly acts on the disc 20 to suck out the contents in the disc 20, so that a certain pressure is formed between the inside of the disc 20 and the outside of the disc 20.

As shown in fig. 1 and 2, a plurality of screening cylinders 23 are distributed at the upper end and the lower end of the disc 20, the bottom ends of the screening cylinders 23 are communicated with the inside of the disc 20, screening holes 24 are arranged at the other surfaces of the screening cylinders 23, the diameter of the screening holes 24 is smaller than that of the soybeans, and the screening holes 24 are used for passing dust and bean hairs, namely, the dust and the bean hairs in the screening shell 10 enter the screening cylinders 23 from the hollow cavity 11 through the screening holes 24 under the pressure difference, then enter the disc 20 from the screening cylinders 23, flow to the fine material discharge port 14 from the outlet 22, and are drawn out from the fine material discharge port 14.

As shown in fig. 1 and 2, the punching holes 17 are formed in the upper end and the lower end of the sieving shell 10, the punching holes 17 are directly communicated with the hollow cavity 11, high-pressure air flows with small diameters are input from the four punching holes 17, the high-pressure air flows input from the four punching holes 17 distributed up and down can effectively perform a turbulence effect on the hollow cavity 11, the high-pressure air flows directly act on the hollow cavity 11, the air flows of the hollow cavity 11 can strongly flow away in a convection manner, and the soybeans are of a round or oval structure with a smooth surface, so that rolling motion is very easy to occur in the air flow motion, the flow area of the soybeans is enlarged, the sieving efficiency of dust and bean hairs is improved, the dust and the bean hairs mixed in the soybeans can be completely sucked away by the sieving cylinder 23, and the sieving efficiency is greatly improved.

As shown in fig. 1 and 2, the hollow cavity 11 is communicated with the coarse material outlet 15, the spoilers 25 are disposed inside the coarse material outlet 15, two ends of each spoiler 25 are fixed to two inner sides of the coarse material outlet 15 through the brackets 26, and the spoilers 25 block the outlet of the coarse material outlet 15 from the front, so as to prevent soybeans in the hollow cavity 11 from directly flowing out of the coarse material outlet 15 without movement, which may cause incomplete screening. A plurality of guide plates 27 are further arranged in the coarse material discharge port 15, the orientation of every two adjacent guide plates 27 is opposite, and the guide plates 27 are arranged to prevent linear movement of air flow, so that screening of soybeans in the hollow cavity 11 is facilitated.

As shown in fig. 1 and 2, a clamping seat 18 is further disposed at an outer end of the screening housing 10, a clamping groove 19 is disposed on the clamping seat 18, and the screening housing 10 can be fixed and supported by the clamping groove 19.

As shown in figures 1 and 2, after the soybeans enter from the feed inlet 13, firstly, the soybeans rotate along the screening cylinder 23, dust and bean hairs are sucked into the screening cylinder 23 during the movement, then the movement track of the soybeans is disturbed under the impulsive force of high-pressure gas of the upper and lower punching holes 17, the soybeans roll around the disc 20, the dust and the bean hairs attached to the soybeans are thoroughly removed in the rolling movement and are screened by the screening holes 24, finally, the soybeans are extruded into the coarse material discharge hole 15 from two sides of the spoiler 25 under the difference of internal and external pressure, and are extruded out of the coarse material discharge hole 15, so that the screening effect is obvious, the screening is thorough, the soybeans are not blocked even if being extruded due to smooth and round or oval structures, and if the soybeans are blocked, the input pressure of the four punching holes 17 can be adjusted, the moving direction of the soybeans is changed, so that the problem of blockage is solved. The screening efficiency was very clear.

In summary, compared with the prior art, the soybean dust sieving device provided by the invention has the advantages that the sieving cylinder bodies distributed in a staggered manner are arranged in the hollow cavity, soybeans, dust and soybean hairs are separated from the sieving cylinder bodies through the sieving cylinder bodies, the dust and the soybean hairs are sucked away from the sieving cylinder bodies, the soybeans are extruded out from the coarse material discharge hole, and due to the fact that the four stamping holes are formed, air flow with certain pressure is introduced through the stamping holes, the soybeans can do multi-wheel and irregular rolling motion in the hollow cavity, the dust and the soybean hairs are easier to suck away from the sieving cylinder bodies, and the soybeans can be completely and thoroughly separated from the dust.

The present invention has been described in terms of embodiments thereof, which are illustrative and not restrictive, and it is to be understood that the scope of the invention is not limited thereto, and that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined in the appended claims, and all such modifications and changes are intended to be included within the scope of the invention.
