Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a contaminant treatment device for a sorter.

In a device that connects a sorter to a horizontal cyclone to remove foreign matter from grains (brown rice, etc.), if the discharge port of the foreign matter receiving box installed in the cyclone is not fully opened and closed, the airflow inside the machine will deteriorate. In addition, conventional airtight discharge valves have drawbacks such as high cost and difficulty in increasing the volume.

In view of the above points, the present invention improves ventilation when discharging foreign matter by providing a discharge port consisting of a rotating cylinder and an elastic pressing plate peculiar to the foreign matter receiving box provided on the cylinder wall of the horizontal cyclone. In addition to stabilizing the airflow condition inside the aircraft by suppressing it as much as possible, we will develop a device that will easily respond to changes in capacity and will ensure that high-efficiency sorting elements are carried out reliably and smoothly. This is what we intend to provide.

The present invention will be explained with reference to embodiment figures. Figure 1,
In FIG. 2, the center of the sorting machine 1 has a large number of comb-like hawks 2A and slits 2B on its circumferential surface.
A pair of rotary sorting tubes 3, 3 each provided with a rotary sorting tube 3, 3 are mounted in parallel with a gentle inclination, and each sorting tube 3, 3 is connected to a motor 5, 5 by providing an annular body 4, 4 for transmitting rotation. The sorting tubes 3, 3 are formed to rotate, and below the sorting tubes 3, 3, unripe rice receiving troughs 6, 6 and screw conveyors 7, 7 are provided. The high end of the sorting tubes 3, 3 communicates with a brown rice supply port 9, and the other end communicates with a refined rice discharge port 10, and the rotary sorting tubes 3, 3 communicate with each other.
An air supply path 13 containing a horizontal cyclone 11 and a fan 12 is provided further below.
3 and connect the respective discharge sides of cyclone 11.
The suction port 15 and the supply side of the sorting tubes 3 and 3 are connected through the ventilation passage A, 16 is a foreign matter receiving box provided on the tube wall of the cyclone 11, 17 is a large foreign matter sorting section provided on the sorting tube 3, 18 is a large foreign matter discharge port, and 19 is a rotating roller that supports the rotating sorting cylinder 3.

The foreign matter receiving box 16 will be explained with reference to FIGS. 2 and 3. A dirt receiving box 6 is provided on the exhaust side cylinder wall of the horizontal cyclone 11 suspended horizontally at the bottom of the machine frame 8, and the discharge port 20 of the receiving box 6 has multiple rows of protrusions on its circumferential surface. A rotary discharge cylinder 22 provided with 21 . 24 is a cover plate for preventing air blowing, 25
is the rotation axis of the rotating cylinder.

With the above-mentioned configuration, the brown rice inputted from the supply port 9 is gradually sent to the lower side as the rotary sorting cylinder 3 rotates, and the brown rice larger than the slit 2B is collected as a large foreign material at the end of the rotary sorting cylinder 3. Large foreign substances such as stones are separated in the sorting section 17, and the rice is discharged from the refined rice discharge port 10 and sent to the next process. Immature rice smaller than the slit 2B falls from the slit 2B into the unripe rice receiving trough 6, is discharged by the screw conveyor 8 through the immature rice discharge path, and is scooped up by the comb-shaped hawk 2A. Contaminants such as debris, strings, and dust are sucked by the fan 12 while falling from the upper part of the cylinder, flow into the horizontal cyclone 11 through the ventilation path A, and swirl inside the cylinder to reach the discharge side cylinder. The foreign matter flows into a foreign matter receiving box 16 provided on the wall and is stored therein. These contaminants are removed by the rotation of the rotary discharge cylinder 22 provided at the discharge port 20 in a state where the ventilation between the protrusions 21 and the pressing elastic plate 23 is suppressed as much as possible. It is extruded and discharged outside the machine.

In the second aspect of the present invention, the elastic pressing plate 23 presses a soft plate material 23A such as rubber with an elastic spring 23B, so that the structure is simplified and installation is facilitated. This has the effect of ensuring sufficient airtightness when discharging foreign matter and preventing wear of the abutting protrusions.

According to the third aspect of the present invention, the protrusions 21 of the rotary cylinder are cleaned by coming into contact with a scraping plate 26 provided on the side thereof, so that the upper end of the protrusions and This has the effect of smoothing the rotation of the rotary cylinder and improving the discharge efficiency without dust, foreign matter, etc. being caught between the cover plate 24 and the cover plate 24.

Note that the rotating means for rotating the rotating cylinder can also be performed manually.

As described above, the contaminant processing device for a sorter of the present invention has a plurality of rows of protrusions on the circumferential surface of the contaminant receiving box provided in the cylindrical wall of the horizontal cyclone that communicates with the inside of the sorter. A rotary discharge cylinder and an elastic pressure plate are installed so that they are in constant contact with each other, which prevents as much ventilation as possible between the foreign object receiving box and the outside of the machine, stabilizes the airflow inside the machine, and improves the efficiency of the sorting machine. Contaminants can be efficiently discharged without reducing sorting performance, and the simple structure makes it easy to respond to changes in capacity, making it possible to reliably, smoothly and quickly mass produce high-quality selected grains. It is something.
