Stirring device

Abstract

The invention belongs to the technical field of fluid stirring, and discloses a stirring device which comprises a tank body, a middle shaft and a stirring piece, a driving piece is arranged on the tank body, the middle shaft is located in the tank body, one end of the middle shaft is connected to the output end of the driving piece, and the driving piece can drive the middle shaft to rotate around the axis of the middle shaft; The stirring part comprises a plurality of blades, one end of the blades is hinged to the middle shaft, a plurality of blades are evenly distributed around the circumference of the middle shaft, and when the middle shaft rotates, the blades can be driven to rotate into a plane perpendicular to the middle shaft. The included angle between the blades and the middle shaft can be adjusted to be small or even overlapped, and the blades are not influenced by the length of the blades when entering through the tank opening of the tank body, so that the blades can be set to be large in size, and the driving piece drives the middle shaft to rotate when stirring is needed; under the effect of rotating centrifugal force, the blades rotate into the plane perpendicular to the middle shaft from the free drooping state, the blades with the large size can be unfolded to fully stir the coating, and the stirring device is suitable for stirring the coating with the high solid content and the high viscosity.

Description

technical field [0001] The invention belongs to the technical field of fluid stirring, and in particular relates to a stirring device. Background technique [0002] The anti-corrosion of marine engineering products belongs to heavy anti-corrosion, and its coating has the characteristics of high solid content and high viscosity. Among them, epoxy two-component coating accounts for more than 70% of the total consumption. According to the statistics of China Shipbuilding Industry Association, China's shipbuilding industry reached 36.9 million in 2019. Tons (approximately 25 million square meters of coating volume), about 15 million liters of epoxy two-component coatings are needed, suitable for supply in large packages of 500-1000L / can, due to its high solid content, after using large-volume cans , easy to produce precipitation, in order not to affect the anti-corrosion life of the paint film, full stirring before use is very important. [0003] The diameter of the tank mouth ...

AI Technical Summary

Problems solved by technology

[0003] The diameter of the tank mouth of the agitator currently used is small, and the propeller blades used are small, which cannot fully agitate the coating in the tank, and cannot meet the mixing requirements of heavy-duty anti-corrosion coatings with high solid content and high viscosity; high-viscosity coatings are easy to hang on the wall and Accumulation of deposits and serious residues are not conducive to paint consumption and cost control; in order to stir high-viscosity paint, the stirring power needs to be increased, and increasing the stirring power will easily cause the blade to break
