Abstract

本实用新型公开了一种沼气池，涉及一种沼气发生装置，本实用新型的目的是提供一种造价低而使用寿命长的沼气池。本实用新型的技术方案是，一种沼气池，包括池体，在池顶壁的内表面设有一托架，密封膜置于池顶壁与托架之间。所述托架与池顶壁内表面形状相吻合。本实用新型用于小型沼气发生装置。

Description

一种沼气池
技术领域：
本实用新型涉及一种沼气发生装置，特别是一种沼气池。
背景技术：
沼气池一般采用混凝土砌成，池体埋在地层中，这种沼气池由于造价低广泛用于农村家户。这种混凝土沼气池在使用过程中由于池体沉降或者老化使池顶部出现裂缝，导致漏气，沼气池报废。由于上述原因，这种沼气池的寿命较短，有的寿命仅有2-3年。
发明内容：
本实用新型的目的是提供一种造价低而使用寿命长的沼气池。本实用新型的技术方案是，一种沼气池，包括池体，其特征在于：在池顶壁的内表面上设有一托架，密封膜置于池顶壁与托架之间。所述托架与池顶壁内表面形状相吻合。本实用新型由于在池顶部的内壁上设置了由塑料膜和托架组成的密封机构，因而与现有技术比较具有使用寿命长而造价低的优点。
附图说明：
图1是本实用新型沼气池的纵剖面图，图2是图1的A向局部视图。
具体实施方式：
结合以上附图对本实用新型作详细说明，沼气池的池体1埋在地表下，沼气池出管5外露在地表上，沼气池的两侧设有进料口6和出料口2，这种沼气池结构简单、造价低，发生裂缝漏气主要在池的顶壁3中。为了解决此问题，在池顶壁3的内表面上设置一塑料膜4，该膜由一个与顶壁相吻合的弧形辐射条组成的托架7支撑在顶壁的内表面，托架可用塑料制成，重量轻，造价低。安装方法是，当混凝土沼气池建成后，将一个与顶壁内表面形状相同的塑料膜4放在托架7上，然后使托架和塑料膜贴在顶壁内表面上并将托架固定在池体上，此时便可投料使用3，当产出沼气后，沼气的压力自然将塑料膜贴在顶壁上，如果池顶壁出现缝隙时，由于有塑料膜的密封作用，不会发生泄露气的事故，可使沼气池的寿命大大延长。

Claims (2)

1、一种沼气池，包括池体，其特征在于：在池顶壁的内表面上设有一托架，密封膜置于池顶壁与托架之间。
2、如权利要求1的一种沼气池，其特征在于：所述托架与池顶壁内表面形状相吻合。
