Three-dimensional composite spiral spray stirrer

Abstract

The invention relates to a three-dimensional composite spiral spray stirrer. The three-dimensional composite spiral spray stirrer comprises a fluid inlet pipe, a flow-guiding hood, a sealing permanent seat, a rotating hood and two declination rotary nozzles, wherein the lower end of the fluid inlet pipe is connected with a flange connection seat, the upper end of the fluid inlet pipe is connected with the flow-guiding hood, the lower end of the sealing permanent seat is fixed on the flow-guiding hood, the upper end of the sealing permanent seat is connected with the rotating hood, the rotating hood is internally provided with a transmission mechanism, the flow-guiding hood is internally provided with a driving impeller, the two declination rotary nozzles are installed on the rotating hood, the two declination rotary nozzles are respectively communicated with the annular channel of the sealing permanent seat, the annular channel of the sealing permanent seat is communicated with the inlet pipe, the rotating hood is fixedly connected with the sealing permanent seat through a large bevel gear, and the two declination rotary nozzles are connected with the rotating hood through small bevel gears. The motion trajectories of the rotating hood and the nozzles are overlapped to form an omni-directional spherical trajectory and realize the function of three-dimensional and omni-directional spraying.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a three-dimensional compound rotary jet agitator which uses fluid jet to stir the storage liquid. Background technique [0002] For some large and medium-sized crude oil storage tanks, various oil blending tanks and other equipment, during use, long-term storage of liquids will cause deposition. For example, due to the long-term storage of crude oil in the crude oil storage tank, asphalt colloids and other organic matter in the crude oil are deposited, which makes the transportation of crude oil difficult. It is necessary to empty and clean the storage tank regularly or irregularly, and each cleaning requires a long period of time. , greatly reducing the utilization rate of the oil tank; at the same time, during the process of emptying and cleaning, the deposited asphalt colloid and other organic matter cannot flow, and are removed and discharged from the oil tank as waste, resulting in a l...
