Description
本發明有關於一種濾網清潔活動刮刀。The invention relates to a movable cleaning blade for a filter screen.
使用廢棄塑料製品作為原料,其原料會投入至回收製粒系統作初步粉碎乾燥,而後入料至系統之熱熔押出螺桿内使其加熱至一定溫度具有流動性,接著熱熔塑料會通過過濾系統,由過濾系統將非塑料物質過濾排除。而後,過濾的塑料會從回收製粒系統之模板製粒裝置擠壓出料、冷卻切粒而成。然而,濾網上的廢渣會逐漸累積導致過濾效率低,因此必須時常更換濾網或以刀具刮除附著於上的廢渣。Using waste plastic products as raw materials, the raw materials will be put into the recycling granulation system for preliminary crushing and drying, and then fed into the system's hot melt extrusion screw to heat it to a certain temperature with fluidity, and then the hot melt plastic will pass through the filtration system Non-plastic materials are filtered out by the filtration system. Then, the filtered plastic is extruded from the template granulation device of the recycling granulation system, cooled and pelletized. However, the dross on the filter screen will gradually accumulate, resulting in low filtration efficiency. Therefore, the slag on the screen must be replaced frequently or scraped off with a knife.
習知技術的刀具是固定刀,因此刀具相對濾網的位置及角度都是固定的。然而,當刀具經長期使用磨耗後,其與濾網之間會產生間隙而無法緊密貼合,導致除渣的效果降低。再者,習知技術的刀具,其硬度大於濾網,造成刀具容易刮傷濾網而造成濾網損耗,又刀具與濾網之間的也會因刀具的磨損而漸大,導致刮除效率低,且當刀具磨損後,必須將整座刀具換掉,增加使用成本。The knives of the conventional technology are fixed knives, so the position and angle of the knives relative to the screen are fixed. However, when the tool is worn over a long period of time, a gap will be created between the tool and the filter screen, which will not fit tightly, resulting in a reduction in the effect of slag removal. In addition, the hardness of the cutting tools of the conventional technology is greater than that of the filter screen, which causes the tool to easily scratch the filter screen and cause loss of the filter screen, and the wear between the tool and the filter screen will gradually increase due to the wear of the tool, resulting in scraping efficiency. Low, and when the tool is worn, the entire tool must be replaced, increasing the cost of use.
因此,有必要提供一種新穎且具有進步性之濾網清潔活動刮刀,以解決上述之問題。Therefore, it is necessary to provide a novel and progressive filter cleaning movable blade to solve the above problems.
