Document Type and Number:
Japanese Patent JP6462516
Kind Code:
B2
Abstract:
In a crushing apparatus installed in a waterway, a conventional crushing apparatus has a screen stacked with screen bars having a horizontal shape, so that a problem that the screen is deformed by bending gradually generated by a self-weight of the screen bar exists. Therefore, the present invention has a purpose to suppress screen deformation due to the bending of the screen bar in the crushing apparatus installed in the waterway. To solve the problem, the crushing apparatus provided includes: a screen for collecting an impurity in water to be treated; a crushing unit for crushing the impurity; and a scraping unit for scraping the impurity collected by the screen to the crushing unit, wherein the screen has a panel member having a slit formed in the approximately horizontal direction and a collecting portion formed at upper and lower parts of the slit to collect the impurity. Therefore, the bending due to the screen bar is able to be suppressed.
