The utility model provides a sealing ring of the nozzle short pipe and the upper body plate of the screen box, including the seal ring body, the center of the seal ring is provided with a tube hole, the nozzle short pipe passes through the tube hole, the sealing ring is provided with an upper seal pad and a lower seal pad, the upper seal pad and the lower seal pad are formed in one, and between the upper seal and the lower seal pads. There is a groove, the edge of the upper body plate of the sieve box is extended into the groove. The width of the slot is fit to the thickness of the edge of the body plate on the screen box. The length of the groove is greater than the distance of the upper body plate on the sifter, and the outer diameter of the upper sealing pad is larger than the outer diameter of the lower seal pad. The sealing ring is designed to make the seal more tight through the design of two sealing gaskets up and down. There is no gap between the body plate and the sealing ring of the screen box, preventing the overflow of acid gas, preventing the dirty things falling into the sieve box, preventing the material from the sifter to cause the dirty surface of the equipment.

喷嘴短管与筛箱上体板的密封圈
本技术属于密封配件领域,特别涉及一种喷嘴短管与筛箱上体板的密封圈。
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。玉米淀粉加工中要使用亚硫酸来浸泡玉米颗粒,因此在筛箱内也存在着酸气,酸气的逸出,对工人的健康产生不利的影响。传统喷嘴短管与筛箱上体板因密封圈是贴着上体板而已,工人更换喷嘴时容易使密封圈移动,导致出现缝隙,这会出现以下弊端:①酸气逸出;②脏东西掉到筛箱内,影响产品质量;③筛内物料从缝隙出来,导致设备表面脏。因此,现在亟需一种密封效果更好的喷嘴短管与筛箱上体板密封圈。
技术实现思路
本技术提出一种喷嘴短管与筛箱上体板的密封圈,解决了现有技术中喷嘴短管与筛箱上体板密封圈密封效果不好的问题。本技术的技术方案是这样实现的:一种喷嘴短管与筛箱上体板的密封圈,包括密封圈本体,所述密封圈本体的中央设有管孔,喷嘴短管穿过所述管孔,所述密封圈本体上设有上密封垫和下密封垫,所述上密封垫和所述下密封垫为一体成型,所述上密封垫和所述下密封垫之间设有卡 ...
