进一步地,所述进水口13设于罐盖11的盖板。然本设计不限于此,于其他实施例中,所述进水口13也可设在罐体12的上端。当然,本实施例中,将所述进水口13设在罐盖11的盖板上,可使得冷罐1获得更高的水位;另外,还可简化罐体12的结构。可选地,罐盖11的盖板在所述进水口13处设有内接头112,导流管2的进水端套接于该内接头112,如此,可便于实现导流管2进水端与所述进水口13之间的连通。Further, the water inlet 13 is provided on the cover plate of the tank cover 11. However, the design is not limited to this. In other embodiments, the water inlet 13 may also be provided at the upper end of the tank 12. Of course, in this embodiment, arranging the water inlet 13 on the cover plate of the tank cover 11 can enable the cold tank 1 to obtain a higher water level; in addition, the structure of the tank body 12 can also be simplified. Optionally, the cover plate of the tank cover 11 is provided with an inner joint 112 at the water inlet 13, and the water inlet end of the diversion tube 2 is sleeved on the inner joint 112. In this way, it is convenient to realize the water intake of the diversion tube 2 The connection between the end and the water inlet 13.
进一步地,导流管2设置为U形管,如此,导流管2的结构简单,且能很好地将进水导流至减速板10的下侧面;然本设计不限于此,于其他实施例中,导流管2还可以设置成其他形状,例如但但不限于呈螺旋形,只要能将进水导流至减速板10的下侧面即可。Further, the flow guide tube 2 is configured as a U-shaped tube, so that the flow guide tube 2 has a simple structure and can well divert the inlet water to the lower side of the speed plate 10; however, the design is not limited to this, and other In the embodiment, the guide tube 2 can also be arranged in other shapes, such as but not limited to a spiral shape, as long as it can divert the inlet water to the lower side of the speed plate 10.
进一步地,减速板10的下侧面设置为满布凸起及/或凹坑的粗糙面,如此,可增强减速板10下侧面对水膜的减速效果,从而避免水膜在冲击到减速板10的边缘时,仍有较高的冲击速度。可选地,当减速板10为金属板(通常为不锈钢板)时,可通过酸洗的方法对金属板的下侧面进行处理,以使其下侧面变成粗糙面。另外,可选地,当减速板10为塑料板时,可通过满布凸起及/或凹坑的注塑模具,直接注塑出下侧面为所述粗糙面的减速板10。然本设计不限于此,于其他实施例中,还可在减速板10的下侧面上贴设具有粘性阻尼特性的材质,例如但不限于食品级的硅胶膜,来提高减速板10下侧面对水膜的摩擦力,从而增强其减速效果。Further, the lower side surface of the speed brake 10 is configured as a rough surface full of protrusions and/or pits. In this way, the deceleration effect of the lower side of the speed brake 10 on the water film can be enhanced, so as to prevent the water film from impacting the speed brake 10 At the edge, there is still a higher impact velocity. Optionally, when the speed plate 10 is a metal plate (usually a stainless steel plate), the lower side of the metal plate can be treated by pickling, so that the lower side becomes a rough surface. In addition, optionally, when the speed brake 10 is a plastic plate, the speed brake 10 with the rough surface on the lower side can be directly injected through an injection mold full of protrusions and/or pits. However, the design is not limited to this. In other embodiments, a material with viscous damping properties, such as but not limited to food-grade silicone film, can be attached to the lower side of the speed plate 10 to improve the lower side of the speed plate 10 The friction of the water film enhances its deceleration effect.
本申请中,在所述喷射狭缝所喷出水膜的速度、及减速板10直径既定的情况下,可选用具有合适减速效果的减速板10下侧面,以使得最终的水膜半径大于或等于减速板10半径的一半,以及使得最终的水膜边缘与减速板10的边缘之间的距离在10mm~15mm,从而使进水在喷出之后能得到较长的减速冲程,以充分消耗其动能,同时避免进水在喷出之后直接冲击冷罐1的侧壁(通常是罐盖11的盖沿)。In this application, when the speed of the water film sprayed by the spray slit and the diameter of the speed plate 10 are fixed, the lower side of the speed plate 10 with a suitable deceleration effect can be selected to make the final water film radius larger than or It is equal to half of the radius of the speed plate 10, and the distance between the final water film edge and the edge of the speed plate 10 is 10mm~15mm, so that the influent water can get a longer deceleration stroke after spraying to fully consume it. Kinetic energy, and at the same time, prevent the influent water from directly impacting the side wall of the cold tank 1 (usually the edge of the tank cover 11) after spraying.
进一步地,减速板10的与导流管2出水端正对的位置设有分水结构101,该分水结构101形成有沿周向分布的多个分水槽。可以理解,该多个分水槽分别朝向不同的方向,以通过该多个分水槽将所述喷射狭缝喷出的水分散导向到不同的方向,从而使得各个方向的水膜更为均匀。Further, a water diversion structure 101 is provided at a position of the deceleration plate 10 directly opposite to the water outlet end of the guide tube 2, and the water diversion structure 101 is formed with a plurality of water diversion grooves distributed along the circumferential direction. It can be understood that the plurality of water diversion grooves respectively face different directions, so that the water sprayed from the spray slits is dispersed and directed to different directions through the plurality of water diversion grooves, so that the water film in each direction is more uniform.
需要说明的是,本实施例中,仅在减速板10上设置所述分水结构101。然本设计不限于此,于其他一些实施例中,还可仅在导流管2的出水端内设置所述分水结构101。而于其他再一些实施例中,还可既在减速板10上设置所述分水结构101,又在导流管2的出水端内设置所述分水结构101。It should be noted that, in this embodiment, only the water diversion structure 101 is provided on the deceleration plate 10. However, the present design is not limited to this. In some other embodiments, the water diversion structure 101 may be provided only in the water outlet end of the diversion tube 2. In still other embodiments, the water diversion structure 101 can be provided on the speed plate 10 and the water diversion structure 101 can be provided in the water outlet end of the guide tube 2.
