Abstract

The utility model discloses a jet flow agitator, be located the efflux direction the place ahead of the efflux pipe (5) of cauldron, install in cauldron wall (6) through round pin axle (4), the agitator includes impeller (1), splint (2) and spacer sleeve (3), impeller (1) outer fringe is 45 degrees diagonals, jet flow agitator's beneficial effect both can realize jet flow agitator's efflux effect, can also realize the effect that mechanical stirring changes the fluid direction, make the mixing that fluid can be better, rotate with the help of jet flow drive jet flow agitator and mix the make full use of energy, for mechanical agitator, the leakage problem has not been had, the installation and use is all very convenient, frequent maintenance has been avoided.

Description

Jet flow stirrer

Technical Field

The utility model belongs to the technical field of the stirring, especially jet mixer.

Background

Mechanical stirring equipment is widely applied to various reaction processes, and the working process of the mechanical stirring equipment is to transmit the power of a driving device outside a kettle to a stirrer on a stirring shaft in the kettle through a transmission shaft so as to realize the mixing of fluid materials in the kettle. This inevitably presents a sealing problem where the transfer shaft meets the vessel wall. If the operating conditions of the apparatus are high temperature and high pressure and no leakage is permitted, a stirring apparatus with a jet stirrer may be used.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a jet flow agitator for jet flow agitated vessel realizes the good mixed effect to the material in the cauldron.

The utility model provides an above-mentioned technical problem, the technical means of taking is inventing a jet flow agitator, is located the efflux direction the place ahead of the efflux pipe in the cauldron, installs in the cauldron wall through the round pin axle. The stirrer comprises an impeller, a clamping plate and a spacer sleeve. The impeller comprises a flat plate at one end, a flat plate at the other end and a curved plate connected with the flat plate and the flat plate through one side. When the impeller is arranged on the pin shaft, the flat plate at one end is clamped and fixed by the upper clamping plate and the lower clamping plate, the flat plate at the other end is also clamped and fixed by the upper clamping plate and the lower clamping plate, and the distance between the two ends is kept by the isolating sleeve. When the fluid jet device works, fluid is jetted onto the stirrer through the jet pipe, on one hand, the fluid is jetted out through the stirrer impeller, and on the other hand, the stirrer impeller rotates along with the flow of the fluid, so that the direction of the fluid is changed.

Experiments show that when the outer edge of the impeller is in an oblique line shape, vortex is easily formed, and entrainment of surrounding fluid is facilitated, so that the jet effect is greatly exerted, and the mixing effect is better. For convenient installation and manufacture, 4 impellers are generally adopted, the outer edges of the impellers are in a 45-degree oblique line shape, namely, the outer edges of a flat plate at one end and a flat plate at the other end form an angle of 45 degrees with the radial direction, the surface where the outer edge of a curved plate is located forms an angle of 45 degrees with a pin shaft, the outer edge lines of three sections are in smooth continuous transition, and the stirring effect is the best.

The beneficial effects of the utility model are that both can realize the efflux effect of efflux agitator, can also realize the effect that mechanical stirring changes the fluid direction, make the mixing that the fluid can be better, rotate with the help of efflux drive efflux agitator and mix the make full use of energy. Compared with a mechanical stirrer, the leakage problem is avoided, the installation and the use are very convenient, and the frequent maintenance is avoided.
