Description

Technical Field

[0001] The utility model belongs to the technical field of vegetable oil storage, in particular to a self-circulating jet stirring device for a large vegetable oil tank. Background Art

[0002] In most vegetable oil factories, the crude oil produced by pressing and leaching is first stored in crude oil tanks for use. Crude oil tanks are generally designed to be larger, such as 1,000-ton, 3,000-ton, and 5,000-ton oil storage tanks. The crude oil will be stratified after being stored in large tanks for a period of time. The upper crude oil is relatively clear, while the lower crude oil is relatively viscous due to the precipitation of phospholipids, proteins, water and residues. During refining, the different quality of the upper and lower crude oils affects the stability of production. Various refining parameters are automatically controlled and basically do not change once set. If the crude oil quality is different, the changes in various parameters will inevitably be affected, which is not conducive to production control. Utility Model Content

There are a plurality of input pipes, which are arranged in parallel up and down, one end of which is connected together and connected to the circulating oil pump, and the other end respectively penetrates the side wall of the tank body and extends to the center of the tank body. One end of each input pipe in the tank body is connected to a plurality of oil spray pipes, and the plurality of oil spray pipes are distributed in a circular array on a horizontal plane with the end of the input pipe as the center of the circle, one end of which is connected to the input pipe, and the other end extends to the side wall of the tank body. Each oil spray pipe is vertically connected to a plurality of nozzles, and the nozzles on the oil spray pipes connected to the same input pipe are all connected to the same side of the oil spray pipe in a clockwise or counterclockwise direction.
