Description

孔隙可调的转盘式养虾池用底排污装置 技术领域
本发明属于水产养殖工程领域，具体地说是一种孔隙可调的转盘式养虾池用底排污装置。
背景技术
对虾养殖过程中为高效排出虾壳、死虾、残饵粪便等污物，需采用间歇式回水工艺(如2017年9月22日公开、公开号为CN107182893A、发明名称为“一种循环水养殖系统间歇式回水装置及其回水工艺”)。采用该工艺技术养虾时，开启间歇式回水瞬间，由于吸污口吸力较大，活虾会随同虾壳、污物等一同吸出到活虾防逃筐内(活虾防逃筐参见2019年3月12日公开、公开号为CN109452215A、发明名称为“循环水养虾系统中去除污物以及活虾防逃的装置和方法”)；因此在生产过程中，为防止过多的活虾被吸出，需要更换底排污装置孔隙，增加工人的劳动量。如何将养殖水体中虾壳、死虾和残饵粪便等污物高效排出，同时防止活虾跟随污物一同排出是养虾系统设计的关键技术。公开号为CN109452215A公开了一种“循环水养虾系统中去除污物以及活虾防逃的装置和方法”，适应于长方形养虾池排污，且不具备孔隙调节功能。因此，如何解决孔隙调节的问题，避免活虾跟随虾壳、死虾一同排出，优化循环水养虾系统整体设计，是循环水养虾产业发展的迫切技术需求。
发明内容
为了解决孔隙调节问题，优化循环水养虾排污装置，便于根据活虾不同规格调节排污孔隙，有效防止活虾跟随污物排出，本发明的目的在于提供一种孔隙可调的转盘式养虾池用底排污装置。
本发明的目的是通过以下技术方案来实现的：
本发明包括弯头、排水管道A、排水管道B、扣板、活虾防逃齿及底盘，其中弯头的两端分别与排水管道B的一端及排水管道A相连通，所述排水管道B的另一端由扣板上开设的螺纹孔穿过、端部连接有底盘，该排水管道B的另一端开设有通孔；所述排水管道B两端之间的外表面上设有外螺纹段，所述扣板通过螺纹孔与该外螺纹段形成螺旋副；所述底盘放置在养虾池的底面，通过扣板与外螺纹段之间的螺旋副，旋转扣板实现扣板相对排水管道B的升降，进而调节所述扣板外边缘下端与养虾池底面之间形成的吸污孔隙的大小；所述扣板外边缘上设有避免活虾近距离接触吸污孔隙的活虾防逃齿；
其中：所述扣板为中间开螺纹孔的圆形板，该扣板的外边缘向下延伸，延伸部的下端与养虾池底面之间形成所述吸污孔隙，所述活虾防逃齿设置在该延伸部 外表面靠近下端的位置；
所述活虾防逃齿为多个，沿圆周方向均布，各所述活虾防逃齿等高、呈水平辐射状排列设置，所述活虾防逃齿与延伸部下端之间的间距为3～8mm，相邻活虾防逃齿之间的间距为15～25mm；
所述活虾防逃齿的一端连接于扣板外边缘上，另一端为球面；
所述扣板上设有便于其旋转的牵引环；
所述弯头与排水管道B连接的一端、排水管道B、扣板及底盘的轴向中心线共线。
本发明的优点与积极效果为：
1.本发明的扣板可根据活虾规格进行上下调节，进而调节吸污孔隙的大小，扣板上设置了避免活虾近距离接触吸污孔隙的活虾防逃齿，利于污物排出的同时，还避免活虾在间歇排水启动瞬间跟随污物被吸出。
2.本发明的吸污孔隙调节可通过手持装置在养虾池外旋转实现，不需要进入养虾池内操作。
3.本发明是配合间歇式回水工艺使用的养虾池用底排污装置，可实现养虾池的高效排污。

图2为本发明的俯视剖视图；
其中：1为弯头，2为排水管道A，3为排水管道B，4为扣板，5为活虾防逃齿，6为底盘，7为吸污孔隙，8为通孔，9为牵引环，10为外螺纹段。
具体实施方式
下面结合附图对本发明作进一步详述。
如图1、图2所示，本发明包括弯头1、排水管道A2、排水管道B3、扣板4、活虾防逃齿5及底盘6，其中弯头1的两端分别与排水管道B3的一端及排水管道A2相连通，排水管道B3的另一端由扣板4上开设的螺纹孔穿过、端部连接有底盘6，该排水管道B3的另一端沿圆周方向均匀开设有多个通孔8；本实施例的弯头1为直角弯头，排水管道A2的轴向中心线与排水管道B3的轴向中心线相垂直。
排水管道B3两端之间的外表面上设有外螺纹段10，扣板4上的螺纹孔开设在中间位置，扣板4通过螺纹孔与该外螺纹段10形成螺旋副。
底盘6放置在养虾池的底面，通过扣板4与外螺纹段10之间的螺旋副，旋转扣板4，螺旋副即转变为实现扣板4相对排水管道B3升降的移动副，进而调节扣板4外边缘下端与养虾池底面之间形成的吸污孔隙7的大小。
扣板4的外边缘上沿周向均布有多个活虾防逃齿5，可以避免活虾近距离接触吸污孔隙7。本实施例的扣板4为中间开螺纹孔的圆形板，扣板4的外边缘向下延伸，延伸部的下端与养虾池底面之间形成吸污孔隙7，活虾防逃齿5设置在该延伸部外表面靠近下端的位置。本实施例的各活虾防逃齿5等高、呈水平辐射状排列设置，活虾防逃齿5与延伸部下端之间的间距为3～8mm，相邻活虾防逃齿5之间的间距为15～25mm。活虾防逃齿5的一端连接于扣板4外边缘延伸部上，另一端为球面。
为了便于扣板4旋转，本实施例在扣板4的上表面沿圆周方向均匀焊接了四个牵引环9。
本实施例的弯头1与排水管道B3连接的一端、排水管道B3、扣板4及底盘6的轴向中心线共线。
本发明的工作原理为：
本发明是配合间歇式回水工艺使用的养虾池用底排污装置，可实现养虾池的高效排污。
将牵引环9上系上绳索，再将本发明的底排污装置放置在养虾池中，底盘6与养虾池的底面接触；在养虾池外通过绳索、牵引环9旋转扣板4，利用扣板4与外螺纹段10之间的螺旋副，转变为扣板4的升降，根据养虾池中活虾的规格调节扣板4外边缘延伸部下端与养虾池底面之间吸污孔隙7的大小，吸污孔隙7的调节范围在0～20mm，利于污物排出的同时避免活虾逃出。污物经吸污孔隙7进入到扣板4与养虾池底面之间，再经通孔8、排水管道B3、弯头1、排水管道A2排出。
