Description

支架式沼气储气罩
技术领域
本发明涉及的是水压沼气发酵装置的活动储气罩,尤其是一种支架式沼气储气罩。
背景技术
中国专利ZL03201184.3《可叠式沼气储气罩》公开了一种适用于沼气装置的活动气罩结构,在这种活动气罩罩体的顶部设有三根筋梁,在筋梁上安装有活动卡件。活动卡件插入沼气发酵装置池口内壁,可将活动气罩固定于池口内。当活动气罩内储存有沼气时,活动气罩由于被固定于池口内,所以不能向上浮起。这种结构的活动气罩在实际使用中,都能满足沼气池发酵装置的使用要求。但是,在实际使用中发现,这种结构的活动储气罩存在以下缺陷:由于罩体是通过三根筋梁与池口的连接来防止其上浮的并得到固定的,即由三根筋梁从罩体的顶部压住储气罩。当活动储气罩受到池内气体压力作用时,受压上浮的罩体在三根筋梁限制下,罩体极易变形。因此,现有储气罩要求罩体必须具有很高的抗变形刚度和强度。它既导致活动储气罩的制造成本提高;也因其结构上的不尽合理,会影响活动储气罩的使用寿命。
发明内容
本发明的目的是针对上述水压沼气发酵装置活动储气罩存在的不足,提供一种可大大降低对罩体抗变形刚度和强度要求的支架式储气罩,从而大大降低储气罩的生产成本,延长储气罩的使用寿命。
本发明的支架式沼气储气罩,包括:设有出气咀的罩体,其特征在于:罩体的罩口设有加强圈;罩体的下沿罩口之加强圈上至少设有两个用于将其固定在沼气池口内的支架。
所述罩体的下沿设有三个支架。
本发明支架式沼气储气罩的设计原理是:将固定储气罩的位置由顶部改为底部下沿,即:将防止罩体上浮并固定的受力点移至罩体的下沿,使得罩体不受压,因此储气罩罩体可保持其自然的半球形而不变形。通过安装在罩体下沿的支架来固定储气罩,则只要求储气罩下沿有高的刚度和强度,而对储气罩罩体的刚度无要求,对罩体的强度要求也极低,所以储气罩罩体甚至可以为软体。
这种结构上的改变,使罩体的受力更加科学,对储气罩罩体的刚度和强度要求大大降低,因此,可大大降低储气罩的生产成本,延长储气罩的使用寿命。
本发明支架式沼气储气罩设计科学,结构合理,方便实用。利用设置在罩体罩口周边的支架,通过插销即可方便地将储气罩固定在沼气池池口内。它既具备了现有活动储气罩的功能和正常使用要求,亦克服了现有活动储气罩整体用材要求严格,制造成本高、使用寿命短等缺陷。是一种更符合使用要求的活动储气罩。
本发明支架式沼气储气罩的具体结构由以下附图和实施例详细给出。
附图说明
图1是支架式沼气储气罩的结构示意图;
图2是图1所示支架式沼气储气罩的分解结构示意图;
图3是一种支架的结构示意图;
图4是另一种支架的结构示意图;
图5是图2所示支架式沼气储气罩A部位放大结构示意图;
图6是图1所示支架式沼气储气罩在沼气发酵装置上的安装示意图。
具体实施方式
实施例:从图1和图2可清楚地看到这是一种顶部设有出气咀12的支架式沼气储气罩,它由罩体1和支架2组成。所述罩体1为半球形壳体结构,罩体1的圆形罩口连接有加强圈11,罩体1顶部设有出气咀12。围绕罩体1罩口之加强圈11安装有三个用于将罩体1固定在沼气池口上的支架2。
所述的支架2如图3所示,支架2由三角架22及设置在三角架22顶角的供插销3穿置的圆筒21构成。三角架22的底边为弧形边221,弧形边221的弧度与加强圈11的弧度相一致。弧形边221上开有供三角架22连接安装的连接孔223,弧形边221通过螺栓固定在加强圈11上。
所述的支架2也可如图4所示,圆筒21与三角架22顶端间为铰连接,三角架22两斜边222端与弧形边221两端亦采用铰连接结构。它可使支架2各连接端成为活关节,以方便调节安装作业。
所述圆筒21为Ω马蹄形结构,圆筒21的开口两条边211上分别开有螺孔;三角架22的两斜边222为S形,斜边222的两头分别开有螺孔;三角架22的弧形边221上设有2个开有螺孔的U形构件224;两斜边222的顶端合拢后插入圆筒21的开口两条边211间,并用螺栓连接;两斜边222的分叉端分别插入弧形边221上的U形构件224内,分别用螺栓连接。这种支架的优点是可调节圆筒21相对三角架22的角度以及三角架22的两条斜边222相对弧形边221的角度,以便于将支架式沼气储气罩在池口内的固定。
为方便消除大气压,储气罩的罩体1顶部设有一配有密封盖14的通气孔13(见图5)。围绕通气孔13内周壁设有螺纹131,并设有供密封胶圈15设置的台阶132;密封盖14底部设有与通气孔13内周壁螺纹131相配的螺纹141,密封盖14与通气孔13间为螺纹配合连接,垫衬在密封盖14与通气孔13台阶132间的密封胶圈15可确保两者间的密封连接。密封盖14的顶部设有出气咀12。
本发明支架式沼气储气罩在混凝土沼气池上安装如图6所示。先在混凝土沼气池的池口4内壁开设与储气罩各支架顶角圆筒21位置相对应的销孔。然后将支架式沼气储气罩置于池口4内,用三个插销3分别穿过支架2的圆筒21并插入池口内壁销孔内,即可将支架式沼气储气罩固定于池口4内。
以上内容是结合具体的优选实施方式,对本发明所作的进一步详细说明,不能认定本发明的具体实施只局限于这些说明。在不脱离本发明构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本发明由所提交的权利要求书确定的专利保护范围。
