The utility model provides a sealing device of screen box front and back doors, including the main body of the sealing strip and sealing strip positioning plate, the main body of the sealing strip is composed of elastic and elastic elastic head tail, head and tail elastic molding, cross section of the elastic head is in a semicircle shape, the tail part of the front end is connected with the elastic elastic head, since the front end to the tail end of elastic elastic tail width increases gradually, a section of the seal of the positioning plate is L, which seal the positioning plate by hypotenuse and straight edge, bevel edge of the top part and the elastic medial head offset, edge part and the elastic outer tail tightly, elastic tail is provided with a smooth transition is symmetric. The front door and rear door sealing device of the screen box ensure the tightness between the arc head and the contact surface of the sealing strip. The sealing form is mosaic, and it is easy to install. It can effectively prevent the material from splashing into the gap between the sealing strip and the sealing strip positioning plate, so as to achieve better sealing effect.
【技术实现步骤摘要】
筛箱前门和后门密封装置
本技术属于密封件领域,特别涉及一种筛箱前门和后门密封装置。
技术介绍
目前,压力曲筛用于玉米淀粉加工中淀粉与纤维的分离工序和纤维的洗涤工序,它是一个安装着120°圆弧状压力曲筛筛面的静止箱体,此静止箱体被称为筛箱。筛箱的前门、后门要密封,防止物料流出。传统的密封形式是用铆钉固定密封槽,若需要更换密封条时,必须将所有铆钉拆掉,换上新密封条后,又要重新打铆钉。这有以下弊端:①拆掉铆钉、重新打铆钉的工作量大;②更换后的前门的铆钉孔,物料容易通过铆钉孔流到筛箱的前门外。因此,现在亟需一种设计更加科学,密封效果更好的筛箱前门和后门密封装置。
技术实现思路
本技术提出一种筛箱前门和后门密封装置,解决了现有技术中普通密封装置密封效果不好的问题。本技术的技术方案是这样实现的:一种筛箱前门和后门密封装置,用于密封筛箱前门或筛箱后门,包括密封条本体和密封条定位板,所述密封条本体由弹性头部和弹性尾部组成,所述弹性头部和所述弹性尾部为一体成型,所述弹性头部的截面呈半圆状,所述弹性尾部的前端与所述弹性头部连接,自所述弹性尾部前端至所述弹性尾部后端宽度逐渐增大,所述密封条定位板的截面呈L型,所述密封条定位板由斜边部和直边部组成,所述斜边部的顶端与所述弹性头部内侧相抵,所述斜边部与所述弹性尾部外缘紧密贴合。作为一优选的实施方式,所述弹性尾部后端对称设有圆滑过渡部。作为一优选的实施方式,所述弹性尾部前端的宽度为8mm。作为一优选的实施方式,所述弹性尾部后端的宽度为9mm。作为一优选的实施方式,所述密封条本体的材质为硅胶。采用了上述技术方案后,本技术的有益效果是:此密封形式 ...
