Description

Technical Field

[0001] The invention relates to the technical field of mixing, and in particular to a stirring device for preparing a scheelite flotation enhancer. Background Art

[0002] Stirring is a kind of circulation through the agitator, so that the gas, liquid and even suspended particles in the solution can be mixed evenly. Scheelite is a type of tungsten ore. Tungsten is a metal element, silvery white crystal, hard and brittle, with a high melting point. It can be made into very fine wires and special alloy steels: tungsten wire, tungsten iron, tungsten steel. When extracting scheelite from mineral water, flotation enhancers need to be added to the mineral water. A stirring device is required during the preparation of flotation enhancers.

[0003] In the prior art, for example, the Chinese patent with the announcement number CN217288191U, entitled A stirring device for preparing a scheelite flotation enhancer, states in the public technical solution that by driving the first pulley transmission mechanism and the second pulley transmission mechanism to work, the hollow connecting tube drives the stirring tube to rotate, driving the stirring paddle to rotate, and achieving mixing and stirring. When the stirring paddle is stirring, the stirring direction of the stirring paddle remains unchanged from beginning to end, so that the material in the stirring tank rotates with the rotation of the stirring blade; after stirring for a certain period of time, the speed difference between the material and the stirring paddle is very small, resulting in poor stirring effect. Summary of the invention

[0004] The present invention provides a stirring device for preparing a scheelite flotation enhancer to solve the above problems.

[0005] The invention discloses a stirring device for preparing a scheelite flotation enhancer, which adopts the following technical scheme: a stirring device for preparing a scheelite flotation enhancer, comprising an outer cylinder, an inner cylinder and a driving mechanism; the outer cylinder is arranged vertically; a feed port is arranged at the upper end of the side wall of the outer cylinder; the inner cylinder is coaxially rotatably installed in the outer cylinder and is located below the feed port; a stirring plate is fixed on the inner wall of the inner cylinder; the driving mechanism comprises a connecting rod, a driving motor and an adjusting component; two connecting rods are symmetrically arranged about the axis of the inner cylinder; the connecting rod is arranged at the upper end of the inner cylinder radially along the inner cylinder; one end of the connecting rod close to the inner wall of the inner cylinder is fixedly connected to the inner cylinder; a driving rod is arranged between the two connecting rods; the driving rod and the connecting rod are coaxially arranged; the driving rod and the connecting rod are rotatably matched.

[0006] The axis of the output shaft of the driving motor is arranged radially along the driving rod; the driving motor is installed in the outer cylinder by rotating around the axis of the driving rod through a supporting assembly; an upper working position of the driving motor is arranged above the driving rod, and a lower working position of the driving motor is arranged below the driving rod; when the driving motor is in the upper working position and the lower working position, the axis of the output shaft of the driving motor is in a vertical state; a force storage torsion spring is connected between the output shaft of the driving motor and the driving rod; when the driving motor is in the lower working position, the driving motor drives the driving rod to rotate forward through the force storage torsion spring, and when the driving motor is in the upper working position, the driving motor drives the driving rod to rotate reversely through the force storage torsion spring; in the initial state, the driving motor is in the lower working position.

[0007] The regulating assembly is used to drive the driving motor to rotate 180° around the axis of the driving rod after each preset time interval, so that the driving motor can be periodically switched between the upper working station and the lower working station. During the stirring process, the driving motor is started, and the driving motor rotates to cause the force storage torsion spring to deform and store energy, and the force storage torsion spring drives the driving rod to rotate forward, and the driving rod drives the inner drum to rotate forward through the connecting rod. After the inner drum rotates for a preset time, the adjusting component drives the driving motor to rotate 180° around the axis of the driving rod, so that the driving motor rotates from the lower station to the upper station, and the driving motor drives the driving rod to reverse through the force storage torsion spring, and the driving rod drives the inner drum to reverse through the connecting rod. In the process of the driving motor rotating from the lower station to the upper station, the inner drum continues to rotate forward under the action of rotational inertia, so that the driving rod drives the force storage torsion spring to further deform and store energy to buffer the rotational inertia of the inner drum in the forward rotation.

[0012] Furthermore, a protective sleeve is sleeved on the lower connecting column; the protective sleeve is fixedly connected to the bottom wall of the inner tube.

[0013] Furthermore, an inner discharge port is provided on the bottom wall of the inner cylinder; an electromagnetic valve is provided at the inner discharge port.

[0016] Furthermore, protective plates are fixed at both ends of the support plate along the axial direction of the support plate; the protective plates are semicircular; and the protective plates and the support plate are concentric.

[0017] The beneficial effect of the present invention is that during the stirring process, the driving motor is started, and the driving motor rotates to cause the force storage torsion spring part to deform and store energy, and the force storage torsion spring part drives the driving rod to rotate forward, and the driving rod drives the inner drum to rotate forward through the connecting rod.
