The invention provides a vortex suction prevention device. The vortex suction prevention device comprises a baffle; the spacing structure is arranged on the baffle; a first opening is formed in the bottom of the bell jar, a second opening is formed in the top of the bell jar, the first opening corresponds to the baffle, the bottom of the side wall of the bell jar is connected with the top end of the spacing structure, and a gap is defined by the side wall of the bell jar, the baffle and the spacing structure; one port of the suction pipe is formed in the upper end of the bell jar and communicated with the bell jar, the suction pipe corresponds to the second opening, and the medium can enter the first opening through the gap and enter the suction pipe through the second opening. The comprehensive performance of low-liquid-level suction and bottom disturbance caused by suction of the suction device can be improved, the medium utilization rate is increased, and the medium cleanliness is improved.

    本申请提供的防涡流吸入装置,包括:挡板;间隔结构,设置于挡板上;钟形罩,底部设置有第一开口,顶部设置有第二开口,第一开口与挡板相对应,钟形罩的侧壁底部与间隔结构的顶端连接,钟形罩的侧壁、挡板和间隔结构围设有空隙;吸入管,的一个端口设置于钟形罩的上端,并与钟形罩连通,吸入管对应第二开口,介质能够通过空隙进入第一开口、经第二开口进入吸入管。能够提高吸入装置低液位抽吸及抽吸对底部扰动的综合性能,提高介质利用率,以及介质的清洁度。
