Fish oil pumping device and pumping method

Abstract

The invention relates to a fish oil pumping device and pumping method. The fish oil pumping device comprises a fish oil temporary storage container, an oil pumping conveying pipeline and two pumping device bodies, wherein the two pumping device bodies are connected in parallel between the fish oil temporary storage container and the oil pumping conveying pipeline and are provided with the same structure; the oil inlets of the pumping device bodies communicate with the fish oil temporary storage container; the oil outlets of the pumping device bodies communicate with the oil pumping conveying pipeline; the bottom height of the fish oil temporary storage container is higher than the oil inlets; each of the two pumping device bodies comprises a cylinder and a piston arranged in the cylinder in a sealing, sliding and sleeving manner; the oil outlets are formed in the opening end parts of the cylinders; an opening-closing plate opens or closes the communicating part between each of the oiloutlets and the oil pumping conveying pipeline; and the upper ends of the opening-closing plates are hinged to the upper end parts of the cylinders. The fish oil pumping device and pumping method canovercome the adverse factor of the existing oil pump to fish oil, generate less heat and can avoid adverse effect of the heat to the fish oil quality.

Description

technical field [0001] The invention relates to a fish oil pumping device and a pumping method, belonging to the field of food processing equipment. Background technique [0002] The oil pump is a light and compact pump having a housing made of a material containing aluminum and a movable molded part arranged in the housing, wherein the movable molded part is at least partly made of A sinterable material comprising at least one austenitic iron-based alloy, and wherein the molding made of a sinterable material has a thermal expansion of at least 60% of the thermal expansion coefficient of the housing coefficient. There are three types of oil pumps: in-line type, distributed type and single type. The oil pumps for general automobile diesel engines at home and abroad are produced by a few professional factories in the world. In the production process of fish oil, oil pumps are also needed, and gear pumps are commonly used, but unlike ordinary mechanical oil or chemical oil, f...

Problems solved by technology

In the production process of fish oil, oil pumps are also needed, and gear pumps are commonly used, but unlike ordinary mechanical oil or chemical oil, fish oil is a biological oil, and severe beating will have a greater impact on its quality At the same time, because the gear pump relies on gear meshing to pump oil, it is easy to generate heat and the temperature rises, resulting in a certain degree of damage to the quality of fish oil
