Description

  The present invention supplies flake raw material liquids such as inorganic and organic substances onto a horizontally rotating table surface, scrapes off the solidified liquid material melted on the table surface, and produces flake-like flakes Relates to the device.

  Conventionally, in the process of producing organic or inorganic substances such as caprolactam, naphthalene, polyethylene glycol, epoxy resin, wax, etc. as products, the packaging and transportation can be facilitated and re-dissolution can be performed smoothly. Thus, the product is flaked in a scale shape.

  As flake manufacturing apparatuses for forming such flakes, drum type and table type flake manufacturing apparatuses are known.

  In a drum-type flake manufacturing apparatus, a molten liquid raw material is supplied and adhered to the surface of a rotating drum as a workpiece, and the workpiece is cooled by supplying a refrigerant into the drum, and the workpiece solidified on the drum surface. Flakes are formed by scraping with a scraper (see, for example, Patent Document 1).

  Further, in the table type flake manufacturing apparatus, the molten liquid material is supplied as a work to the surface of the horizontally rotating table, and the work is leveled to a certain thickness so as to spread over the entire area in the table radial direction. The workpiece is cooled and solidified by spraying the refrigerant from

  A scraper is arranged on the front side of the table rotation direction so that the cutting edge contacts the table or keeps a minute gap with the table, and the work moved by the rotation of the table hits the cutting edge of the scraper. As a result, the flakes are formed by scraping from the upper surface of the table. (For example, refer to Patent Document 2).

In a drum-type flake manufacturing device, gravity that tries to drop is applied to the work solidified on the drum surface, so in the case of a material that is easy to peel off, it will be peeled off from the drum surface before reaching the scraper. Can't get flakes. Therefore, the table-type flake manufacturing apparatus is more suitable when a raw material that is easy to peel off and drop off when solidified is used as a workpiece.

  By the way, in the conventional table type flake manufacturing apparatus, when a workpiece | work was scraped off from the table upper surface by the scraper blade edge | tip, when this workpiece | work self-destructed, it divided | segmented into scaly form and the flake was formed. In such a case, since each flake is divided at random, it is difficult to obtain flakes having a uniform size.

  In addition, when the work material itself has a high bondability, or when the work is relatively thick and uniform, the film strength of the solidified work increases, so it can be peeled off from the table top by the scraper blade edge, There was a problem that the peeled work was not divided and formed into a coarse sheet, and scaly flakes could not be formed. Such sheet-like workpieces cannot be used as products and cannot be automatically ejected from the top surface of the table. Therefore, it was necessary to stop the operation of the equipment to remove it, which lowered productivity. .

The present invention has been made in view of such a problem, and is capable of producing flakes even when the film strength of the solidified raw material is large, and can expand the application range. The purpose is to provide. Another object of the present invention is to
An object of the present invention is to provide a table type flake manufacturing apparatus capable of obtaining flakes having a uniform size.

The plurality of ring-shaped cutting blades can divide the workpiece into a plurality of pieces with the same size in the table radial direction.

  Furthermore, in the table type flake manufacturing apparatus according to the present invention, the workpiece dividing means may include a drive mechanism for rotating the cutter roll. When the ring-shaped cutting blade rotates and contacts the workpiece as the cutter roll rotates, the workpiece can be more reliably and easily divided in the table radial direction.

  According to the table type flake manufacturing apparatus of the present invention, since the solidified raw material is divided by the work dividing means before being scraped off by the scraper, the flakes are manufactured even when the film strength of the solidified raw material is large. Therefore, it is possible to flexibly cope with the case where a raw material having high binding properties is used, the case where thick flakes are manufactured, and the like, and it is possible to expand the application range.
