Abstract

PURPOSE:To efficiently and simultaneously perform the mixing and feed of a material, by providing rotary shafts wherein a large number of blades are alternately fixed to both shafts so as to be arranged in a multistage fashion and the leading ends of the blades are made to mutually approach the opposed shafts to cross each other. CONSTITUTION:When a pulley 5D rotates inwardly, shafts 5, 6 are operated so as to rotate in opposed relationship. When a material is charged to said shafts 5, 6 from a charge port, said material is taken in the gap between blades 5-1, 5-2 by the blade 5-1. When the material is rotated to rise to a crossing part, said material is cut by a blade 6-1 to be taken in the gap between the blades 6-1, 6-2 and subsequently taken in the gap between blades 5-2, 5-3. As mentioned above, cutting is alternately repeated by the blades of each stage and the material alternately moves between dual cylinders to be forcibly fed by one stage and reaches a blade 6-20 to be discharged.

送する方法に限定されることが多い。PRIOR ART The process of mixing and conveying bulk, granular, or powdered materials (hereinafter simply referred to as materials) is often required in today's production processes (various mixing and conveying devices are used separately). However, conveying wet materials is often difficult with equipment that conveys dry materials, and is limited to methods that transport materials in pieces, such as belt conveyors and chain conveyors. There are many.

程も同時に行えれば、生産工程の合理化に役立つ。Because the material in a water-containing state is sticky, for example, in a typical screw conveyor-type conveying device, it is compressed and densified, resulting in clogging. For this reason, there is a need for a conveying means that avoids compaction and prevents clogging. Also, if the mixing process can be performed at the same time, it will help streamline the production process.

る。Means and Effects for Solving the Problems Clogging that occurs when hydrated and sticky materials are conveyed, for example on screw conveyors, is due to continuous propulsion pressure. According to the present invention, the screw function blades (hereinafter simply referred to as blades), which are alternately arranged and fixed on both shafts and each approach the other shaft, rotate with their circular arcs intersecting. Therefore, the input material is transported by the rotating blades on both shafts.
Rotation, cutting at the intersection, and propulsion are repeated alternately between the twin cylinders, resulting in an operation that constantly divides, mixes, and propels the material.

A plurality of blades are alternately arranged and fixed at 20 locations on each shaft at opposite angles (6 to 20 are perpendicular to the discharge 1). Furthermore, gears of 5C and 6C are attached to the 5th axis so as to mesh with each other, and a 5D drive pulley is also attached to the 5th axis.

It is caught between the blades of 6-1 and 6-2, rotates and rises to the intersection, is cut by the blades 6-1, and is taken between the blades 6-1 and 6-2, and then by the blades 5-2. 5-2
It is taken in between the 5th and 3rd blade parts. In this way, cutting is repeated alternately by the blades of each stage, and the blade is propelled one stage at a time while moving alternately between the twin cylinders, and when it reaches 6 to 20 blades, it is scraped out to the exhaust IJ port.
