Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rice husk recovery device that is connected to a dust removing port of a rice huller equipped with a sorting device or a sorting device, and separates and collects rice husks and the like discharged together with the exhaust air from the dust collecting port.
[0002]
[Prior art]
The hulling machine includes a hulling machine and a sorting apparatus which are separately provided, or a hulling machine and a sorting apparatus which are integrally configured. Since it is discharged together with the exhaust air from the dust outlet of the sliding machine, it is desired to collect the discharged rice husk and the like with a collection bag in order to avoid deterioration of the surrounding environment due to the hulling operation. Conventionally, there has been proposed a rice husk recovery device that separates rice husks and the like being exhausted by a cyclone and collects them in a collection bag (see Japanese Utility Model Publication No. 63-25147).
[0003]
By the way, as shown in Japanese Utility Model Publication No. 63-25147, in a conventional cyclone rice husk recovery device, the rice husks separated by the cyclone are carried out from the lower end of the rice husk by a screw conveyor provided horizontally, and collected in a collection bag. In order to secure the collection height of rice husks etc. in the collection bag, the screw conveyor not only needs to exceed the depth of the collection bag, but also in the screw conveyor. The installation position of the cyclone that connects the lower ends is inevitably higher.
[0004]
[Problems to be solved by the invention]
For this reason, the exhaust air introduction position of the cyclone becomes too high from the exhaust port of the sorting device or hulling machine, and not only is the connection between the air discharging port of the sorting device or hulling machine and the cyclone easy, but also between them. Inevitably connected by curved pipes, the flow resistance of the exhaust wind at that part increases, and it is unavoidable that the wind power of the exhaust wind flowing into the cyclone declines and the separation ability of rice husks and the like decreases. There is no actual situation. In addition, since the screw conveyor extends horizontally from the lower end of the cyclone, it is also a problem that a large space is required for installing the rice husk recovery device.
[0005]
On the other hand, the present inventor carefully observed the shape of the swirling air in the conical cylinder constituting the cyclone. As a result, the swirling air acting on the separation of dust is generated along the inner peripheral surface of the conical cylinder. As a result, it was found that the space around the axis of the conical cylinder constituting the cyclone is a dead space (ineffective space) in the separation of dust.
[0006]
Therefore, in order to effectively utilize the dead space in the conical cylinder constituting the cyclone, the present invention penetrates the screw conveyor from the lower part of the conical cylinder constituting the cyclone through the windless space formed along the axis. By providing them, the entire device can be made into a compact configuration centered on the cyclone, and the screw conveyor collects the discharge side of the screw conveyor from where it passes through the upper end of the conical cylinder that constitutes the cyclone. It is possible to secure a sufficient height for collecting rice husks in the bag, and in addition, the cyclone exhaust air introduction position is balanced with the height of the exhaust port of the sorting device or rice huller, and the connection between them is established. This makes it easy to keep the separation resistance of the cyclone in the cyclone low by reducing the flow resistance of the part. And to provide a chaff collection device.
