The device includes an outer tank, a drying tank inside the outer tank, a feed inlet at the top of the drying tank, a discharge outlet at the bottom of the drying tank, a cavity between the outer tank and the drying tank, hot steam delivered into the cavity by a steam furnace, a rotating shaft inside the drying tank, the left and right ends of the rotating shaft penetrating through the left and right sides of the drying tank, the left end of the rotating shaft rotatably connected to the output shaft of motor a, the output shaft of motor a inserted into the left side of the outer tank, the right end of the rotating shaft penetrating through the right side of the outer tank and rotatably connected to the left side of the heating device, a heating core inside the rotating shaft, and the right end of the heating core fixedly connected to the heating device. By setting the heating core and starting the heating device, the heating core releases heat to heat the sodium fluorosilicate powder in the center of the drying tank. Since the drying tank is long and cylindrical, and the discharge outlet is located at the central position of the bottom end of the drying tank, when the dried powder is discharged, the material at the end of the drying tank cannot flow to the discharge outlet. Manual intervention is required to pour the dried material at the end of the drying tank out of the discharge outlet, which consumes labor. SUMMARY

[0003] The utility model aims to provide a kind of sodium fluorosilicate drying equipment to solve the problem that the discharge outlet is located at the central position of the bottom end of the drying tank, and when the dried powder is discharged, the material at the end of the drying tank cannot flow to the discharge outlet.

[0004] To solve the above problems, the technical scheme provided is as follows:

[0005] A sodium fluorosilicate drying equipment includes an outer tank and a drying tank inside the outer tank.

[0006] The basic principle of the above technical solution is that the sodium fluosilicate wet material is poured into the drying tank through the feeding port for drying treatment, and after drying is completed, the discharge port is opened. Since the drying tank is spherical, the discharge port is at the lowest end of the bottom, and the dried material will automatically fall out of the discharge port under the action of gravity.

[0007] The beneficial effects of the above technical solution are that, compared with the existing long cylindrical drying tank, the material at the end of the drying tank cannot flow to the discharge port for discharge, and the drying tank is set to be spherical, and the discharge port is set at the lowest end of the bottom of the drying tank. There is no storage of dried material at the end to cause the material to flow to the discharge port for discharge, saving the discharge processing time and labor cost.

[0008] Further, the hollow rotating shaft is provided in the drying tank, the top end of the rotating shaft extends out of the top end of the outer tank body, the motor is fixedly connected outside the rotating shaft, and the hollow spherical pier head is communicated with the bottom end of the rotating shaft. A plurality of stirring shafts directed to the inner wall of the drying tank are communicated with the hollow spherical pier head, the hollow spherical pier head is located at the center of the drying tank, and heating wires are arranged in the rotating shaft, the hollow spherical pier head and the stirring shafts. The motor drives the rotating shaft to rotate, the rotating shaft drives the stirring shafts to stir in the drying tank, and the heating wires in the rotating shaft, the hollow spherical pier head and the stirring shafts dry the material in the drying tank.

[0009] Further, the rotating shaft is coaxial with the motor output shaft, the top end of the rotating shaft extends out of the top end of the motor, and the power supply is fixedly arranged at the top end of the motor. The power supply supplies power to the heating wires and the motor. The rotating shaft is coaxially arranged with the motor output shaft, the heating wires in the rotating shaft can rotate synchronously with the rotating shaft, and the power supply also rotates synchronously, so that the heating wires do not twist and entangle during rotation.

The arc-shaped scraper rotates with the stirring shaft, can scrape the material attached to the inner wall of the drying tank, avoids that the material is attached to the inner wall of the drying tank for a long time to form a wall, and ensures that the material in the drying tank is evenly dried.

[0011] Further, the outer tank body is provided with an air inlet and an air outlet communicated with the cavity, and a steam furnace is arranged on one side of the outer tank body. The steam outlet of the steam furnace is fixedly connected with the air inlet. The steam furnace enters hot steam into the cavity through the air inlet, so that the heat in the drying tank is more, and the drying efficiency is improved.

[0012] Further, the bottom of the outer tank body is provided with supporting legs. The supporting legs suspend the whole device in the air, facilitating the discharge of the discharge port.

[0013] Further, the inner wall of the outer tank body is provided with a heat insulation layer. The heat insulation layer blocks the heat loss in the cavity, avoiding resource waste. BRIEF DESCRIPTION OF DRAWINGS
