YZX-DBS 雙刮刀裝置(雙刮刀氣囊加壓控制式)

詳細介紹



雙刮刀是兩臺雙氣囊刮刀合用的方式。目的是為了去除附著在輥面上的水分及臟東西為目的。使用過程中,棍子表面上會有許多凹凸不平的小孔,刀刃的磨擦面也會有同樣現象。因而,微小的臟東西及水分就會透過這些小孔,順流到刮刀后表面。由于臟東西有些被紙張帶走,另一些粘結在刮刀背后形成塊狀物,許久過后容易掉下,從而造成斷紙,以致停機。特別是壓榨部的石輥等,此現象比較嚴重。除此之外,刮刀片施加較大的線壓時,會在刀片背后產生負壓,這個負壓會造成在刀片正面堆積許多臟東西,也會嚴重地影響產品質量。
在中心壓榨部、網部伏輥等加裝雙刮刀。利用離心力的作用,伏輥、真空壓輥孔內水及細小纖維非出并附著于輥第一刮刀能破壞其表面張力,清除部分水及細小纖維,并在刮刀之后形成微小負壓將孔內水及細小纖維徹底排出后由第二刮刀清理。
雙氣囊刮刀可以有效的解決這些問題,在保持線壓、材質和角度問題的基礎上,保持輥面的運行清潔,減少斷頭及紙病,并有效保護輥面,延長棍子的使用壽命,減少停機更換維護的頻率,提高經濟效益。
YZX-DAS Double-Blade Device(Double Blades Air Cell Pressure Control) 
The double-blade device, made up by two air-cell blades, it means using two air-cell blades at the same time. It is used to remove the moisture and dirt attached to the roller surface. During the operation, plenty of pores will form on the roller surface as well as on the abrasive side of edge. Therefore, small dirt and moisture will enter into the back surface of blade through these pores. Some dirt will be taken away be paper, while some will attach to the back of blade, forming lumps which will drop after a long time, thus causing paper breakage and even machine halt. Such condition is even more serious for the stone roller in the press section. In addition, a great lineal pressure exerted by the blade may produce negative pressure at the back of blade which causes plenty of dirt to gather on the front of blade, thus seriously affecting product quality. 
The double-blade device is equipped in the central press section, couch roll in the net section and so on. Under the action of centrifugal force, the moisture and fine fibers will be thrown away from the pores of couch roll and vacuum compression roller, and then attach to the first blade which is able to destroy their surface tension, remove part of moisture and fine fibers and form a small negative pressure behind the blade. The second blade will clear away the moisture and fine fibers expelled from the pores by the small negative pressure.
The double air-cell blades can effectively solve these problems. It is able to keep the roller surface clean while maintaining a proper lineal pressure and angle and protecting materials. Besides, it can reduce ends down and paper defects, effectively protect roller surface, prolong the service life of roller, and reduce the frequency of shutdown for replacement and maintenance, thus improving the economic benefit.
