Description

Cylindrical Home Screen Separator {Indent-Screen Separator}

The present invention relates to a cylindrical groove sorter capable of sorting grains of a predetermined size or less by using a difference in length of grain among grain sorters, which is selected from grains in Korean Patent Publication No. 289963 (Registration date February 26, 2001). Well described in the device. In addition to the main purpose of length sorting, the screen sorter which sorts by thickness and size is added to the cylindrical groove sorter that selects only the difference in length among the geometrical characteristics of grains. And a roller brush (4), grain dispersion plate (301), the retarder (5) and the like to improve the sorting capacity and life of the machine.

In general, a variety of types of grain sorter for sorting the size of the grain has been developed and used, in particular, the cylindrical groove sorter rotates the rotary cylinder (2) having the sorting groove 201 and the length of the grain put into the sorting groove (201) It is a device that can sort grains by length using the principle that the drop position is different according to each other.The screen sorting machine puts grain into a plate made of wire mesh, rectangular or circular shape, etc. It is a device that can be selected according to the size of the. Cylindrical grain sorters are effective devices for sorting by using grain length differences, and screen sorters have advantages and disadvantages because they are effective devices for sorting using size differences. It is generally installed after the process (a process of removing rice bran from rice and making it in the form of rice) to sort out the granules generated during processing, and the cylindrical groove sorter is generally installed just before the final packing. However, since the current cylindrical groove sorting machine is installed just before the shipping packaging, the screening ability is poor in the sorting issue issued after the sorting process, such as a number of transfer lines and color screening after screening. Cylindrical groove sorter has excellent sorting power using length difference, but it does not sort out fine debris floating in many sorts at the time of sorting, so it does not meet the quality certification standard. This leads to inefficiencies in installing additional. In addition, since the cylindrical groove sorter in the prior art does not have a grain dispersing device, vibration occurs due to grain pull and agglomeration in the rotating cylinder 2, resulting in a shortened machine life and a poor sorting efficiency. There is a drawback that the sorting efficiency is greatly reduced because there is no device to prevent the spill.

Therefore, the present invention provides a sorting unit in which the perforated screen 202 is perforated at the end of the rotating cylinder 2 in order to improve the drawbacks of the conventional cylindrical groove sorter as described above. Size can be selected while passing through the punching screen 202 and a roller brush 4 for cleaning the punching screen 202 is installed to clean the punching screen 202 so that the punching screen 202 is always in an optimal state. ) To increase the sorting efficiency by installing a grain dispersion plate 301 in the lower portion of the stacking cylinder (3) to prevent grain dispersion and grain dropping so that the grain is evenly spread and stored in the sorting groove 201 to improve the sorting efficiency. At the same time, the grains are aggregated together to gain the advantage of preventing mechanical vibration due to the rotation of the inside of the rotating cylinder (2) to one side, and preventing the outflow of grain before sorting at the end of the rotating cylinder (2). A sorter dam device (5) was installed to increase the efficiency of sorting by temporarily stopping the discharge of grains before sorting instead of spreading them evenly in the rotating cylinder (2). This will be described in detail with reference to the accompanying drawings.

First, Figure 1 is a front view of the present invention showing the proper attachment position of the device for achieving the above object, Figure 3 is a half cross-sectional perspective view of the rotating cylinder (2) and Figure 5 is a grain dispersing plate (301) device 5 As shown in the perspective view of the half-section of the rotating cylinder portion 2 of FIG. 3, the rotating cylinder 2 is approximately 85% of the entire rotating cylinder from the grain inlet 12. The shape of accommodating grains on the wall is made of a sorting groove 201 embossed in a hemispherical shape, and the remaining 15% connected by welding is manufactured by processing a perforated screen 202 with a rectangle of 20 mm in width and 20 mm in length. The size and shape of 202 may be made into a circular oval, depending on the object being selected. In order to keep the perforated screen 202 in an optimal state, as shown in FIG. 4, the link bearing 403 has the main body 1 as a fixed plate so as to be able to contact the perforated screen 202 from the outside of the rotating cylinder 2. ) And a roller brush 4 that is supported and rotated by being supported by a ball bearing 401 with the brush shaft 402 as a rotation axis, and as shown in FIG. Install at the point where the rotation starts. This is to ensure that the taillights safely enter the stack 3 when the taillights stuck in the perforated screen 202 are cleaned by the operation of the roller brush 4. The production of the roller brush 4 is made of synthetic resin or the like, but uses a material that does not harm the human body. If the part of the brush is separated, the roller brush 4 is put into the discharge container and discharged, thereby ensuring stability. The sorted matter discharged to the outside of the rotary cylinder 2 through the perforated screen 202 is discharged to the outside through the tail light discharge port 9. As shown, the grain dispersion plate 301 is fixed at equal intervals by welding or bolts, but the grain can be sufficiently dispersed even by adjusting the angle of the stacking cylinder 3 with the angle adjusting worm gear 6 to control the screening ratio. It is manufactured in a fan shape so that the size can be varied depending on the diameter of the rotating cylinder (2). The installation direction of the distribution plate 301 is installed at about 45 degrees equal intervals so as to match the direction of the transfer screw 302 as shown in the perspective view of FIG. At this time, there is a clearance of about 15 ~ 20mm with the bottom surface of the rotating cylinder (2) to maintain a constant interval. Figure 5 is centered on the integrated cylinder (3) to be located at the end of the rotating cylinder (2) The linker 501 and the connecting Y-nuckle 502 and the retarder 5 interlocked left and right about the integrated cylinder 3 by the adjusting screw 503 and the adjusting handle 504 to enable the angle adjustment are shown. It is a perspective view. Even if the rotating cylinder 2 rotates, the accumulator 3 does not rotate, so that the upper part of the accumulator 5 is processed into a circular hole to be attached to the rounded part of the accumulator, but is not pushed away by the discharged grain. The bracket for preventing the detachment of the retarder 5 is installed in the stacking cylinder 3. The retarder 5 serves as a kind of dam that pauses the grain discharged from the inside of the rotating cylinder 2 so that the grain is discharged toward the edge of the retarder 5, so that it must be supported by the accumulator 3. Although not shown, as shown in a perspective view showing the structure of Figure 5 C can be seen as the most suitable position in the structure of the machine.

With the above-described design, by adding the perforated screen 202 to the end of the rotary cylinder 2 to sort the tails so that the tailings can be sorted on the length sorting function of the cylindrical groove sorting machine, the machine can be effectively installed as a machine that is installed at the pre-packaging stage. Increase the value, install the roller brush (4) on the outside of the perforated screen (202) to always maintain optimal performance, and the grain distribution plate (301) at the bottom of the integrated cylinder (3) inside the rotating cylinder (2) It prevents grain from falling and clumping during operation and distributes the grain evenly so that the sorting groove 201 is accommodated, thereby improving the sorting performance of the machine and preventing vibration to extend the life of the machine and lower the failure rate. In addition, by installing a retarder 5, which serves to temporarily stagnate the grain at the end of the rotary cylinder 2, that is, the point at which the grain is discharged, it is possible to obtain the advantage of preventing the outflow of grain before sorting and increasing the sorting efficiency. have.
