Abstract
本实用新型涉及环保技术领域，尤其是一种平流式初次沉淀池。一种平流式初次沉淀池，包括长方体结构的池体，所述池体的底部一端具有锥形的泥斗，靠近泥斗底部的侧壁上设有排空管，池体上端一侧设有进水管，进水管旁的池体上纵向依次设置有穿孔墙和通气管，通气管上通过三通连接有排泥管，池体上端另一侧设有出水管，出水管旁的池体上纵向依次设置有出水挡板和浮渣槽，池体上端安装有刮泥车，以便刮泥车在池体上端可来回滑动。本实用新型通过在通气管三通连接排泥管，加上池体上端安装刮泥车，从而有效克服现有的平流式沉淀池在沉淀区的底壁容易堆积较多的沉淀物的缺点。

[0001] 本实用新型涉及环保技术领域，尤其是一种平流式初次沉淀池。
背景技术
[0002] 平流式沉淀池的池型呈长方形，在池的进水区的底部设贮泥斗，沉淀区的底壁有坡度，倾向贮泥斗。废水从池的进水区流入，水平方向流过池子，从池的出水区流出。平流式沉淀池对冲击负荷和温度变化的适应能力较强，施工简单，造价低；其适用于大、中、小型污水处理厂。但现有的沉淀池整体对废水的沉淀情况较为一致，在沉淀区的底壁容易堆积较多的沉淀物，而不是使大部分的沉淀物能够在进水区便沉淀到贮泥斗中，故需要经常对沉淀区的底壁进行刮泥，从而降低沉淀效率，增加成本。
实用新型内容
[0003] 本实用新型要解决的技术问题是:基于上述问题，提供一种平流式初次沉淀池，从而克服现有的平流式沉淀池在沉淀区的底壁容易堆积较多的沉淀物的缺点。
[0004] 本实用新型解决其技术问题所采用的技术方案是:一种平流式初次沉淀池，包括长方体结构的池体，所述池体的底部一端具有锥形的泥斗，靠近泥斗底部的侧壁上设有排空管，池体上端一侧设有进水管，进水管旁的池体上纵向依次设置有穿孔墙和通气管，通气管上通过三通连接有排泥管，池体上端另一侧设有出水管，出水管旁的池体上纵向依次设置有出水挡板和浮渣槽，池体上端安装有刮泥车，以便刮泥车在池体上端可来回滑动。
[0005] 进一步地，所述排泥管延伸至泥斗底部。
[0006] 进一步地，所述排空管上设有阀门。
[0007] 进一步地，所述池体上端设有一圈护栏。
[0008] 本实用新型的有益效果是:本实用新型通过在通气管三通连接排泥管，加上池体上端安装刮泥车，从而有效克服现有的平流式沉淀池在沉淀区的底壁容易堆积较多的沉淀物的缺点。

具体实施方式
[0013] 现在结合附图对本实用新型作进一步详细的说明。这些附图均为简化的示意图，仅以示意方式说明本实用新型的基本结构，因此其仅显示与本实用新型有关的构成。
[0014] 如图1〜2所示，一种平流式初次沉淀池，包括长方体结构的池体1，池体I的底部一端具有锥形的泥斗2，靠近泥斗2底部的侧壁上设有排空管3，排空管3上设有阀门4，池体I上端一侧设有进水管5，进水管5旁的池体I上纵向依次设置有穿孔墙6和通气管7，通气管7上通过三通8连接有排泥管9，排泥管9延伸至泥斗2底部，池体I上端另一侧设有出水管10，出水管10旁的池体I上纵向依次设置有出水挡板11和浮澄槽12，池体I上端安装有刮泥车13，以便刮泥车13在池体I上端可来回滑动。进一步地，池体I上端设有一圈护栏14。
[0015] 水由进水管5通过穿孔墙6上均匀分布的进水孔流入池体1，穿孔墙6后设有挡板，使水流均匀地分布在整个池宽的横断面；出口多采用溢流堰，以保证沉淀后的澄清水可沿池宽均匀地流入出水渠。堰前设浮渣槽12和挡板11以截留水面浮渣。水流部分是池的主体，池宽和池深要保证水流沿池的过水断面布水均匀，依设计流速缓慢而稳定地流过。泥斗2用来积聚沉淀下来的污泥，多设在池前部的池底以下，斗底有排泥管9，定期排泥。
[0016] 以上述依据本实用新型的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项实用新型技术思想的范围内，进行多样的变更以及修改。本项实用新型的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
