Tesla valve type drainage plate and manufacturing method and application thereof
The invention discloses a Tesla valve type drainage plate. The Tesla valve type drainage plate comprises an air source device, wherein the air source device is connected with a drainage plate core through an air source air delivery pipe and a flow divider; the drainage plate core and a filter membrane form a complex; drainage grooves are formed in the surfaces of the outer walls of the two sides of the drainage plate core; Tesla valves are vertically arranged in the drainage plate core and correspond to the drainage grooves; holes are asymmetrically formed in the bottoms of the drainage grooves; air inlets are formed in the tops of the Tesla valves; air guide channels are formed in the Tesla valves; air holes are formed in the outer walls of the air guide channels and are connected with one of the ends of branch pipes with inverted membranes; and the other one of the ends of the branch pipes is adhered to the corresponding hole in the bottom of each drainage groove. The Tesla valve type drainage plate has the beneficial effects that airflow enters from the Tesla valves in the forward direction, is accelerated by the Tesla valves and is sprayed out from the openings of the polypropylene branch pipes with the inverted membranes; and the accelerated sprayed airflow acts on soil particles and the filter membrane blocking the drainage grooves via the asymmetric small holes in the drainage plate, has a pushing effect on soft clay particles on the drainage plate and solves the problem that pits are easily formed in the drainage grooves as the filter membrane has weak lateral pressure resistance.
本发明公开了一种特斯拉阀式排水板，包括气源装置，气源装置经气源输气管、分流器连接排水板芯，排水板芯与滤膜组成复合体，排水板芯两侧外壁表面形成排水槽，排水板芯内部对应排水槽竖直布置特斯拉阀，排水槽槽底不对称开孔，特斯拉阀顶部设有进气口，特斯拉阀内部为导气通道，导气通道外壁上开设风孔，风孔与带倒膜的支管一端连接，支管另一端与排水槽槽底的孔粘接。气流从特斯拉阀正向进入，经过特斯拉阀加速，从带倒膜的共聚丙烯支管口喷出；加速喷出的气流经排水板上不对称小孔作用到堵塞排水槽的土颗粒和滤膜上，对排水板上的软粘土颗粒有推动作用，并且解决因滤膜抗侧压能力弱，容易在各排水槽处产生凹陷的问题。
