Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand cooling, in particular to a quartz sand cooling device. Background Art

[0002] Quartz sand is quartz particles obtained by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is an important industrial mineral raw material, widely used in industries such as glass, casting, ceramics, fireproofing, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, and filter media.

[0003] After the existing quartz sand is processed, its internal temperature will increase. Quartz sand is usually cooled naturally by standing still, and the cooling speed is relatively slow, which is not convenient for subsequent work. Therefore, those skilled in the art provide a quartz sand cooling device to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to provide a quartz sand cooling device in order to solve the problem that the cooling speed of quartz sand is relatively slow.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quartz sand cooling device, characterized by comprising a cylindrical cooling box, a cover plate disposed on the top of the cylindrical cooling box, a feed port disposed on the cover plate, a stirring device disposed within the cylindrical cooling box, an outlet disposed at the bottom, and a cooling output device fixedly connected below the outlet. The cooling output device includes a cooling pipe, the cooling pipe being a horizontally arranged cylindrical shape, the outlet being seamlessly fixedly connected to the cooling pipe, a conveying device disposed within the cooling pipe, a first drive motor disposed at one end of the cooling pipe near the outlet, and a discharge port at the other end.

[0006] As a further embodiment of the present invention, the conveying device includes an auger blade and a first rotating shaft, the auger blade being mounted on the first rotating shaft, the first rotating shaft being arranged along the central axis of the cooling pipe, and one end of the first rotating shaft being connected to the output end of the first drive motor. This arrangement of the conveying device not only prevents blockage of the cooling pipe but also allows the discharge speed to be adjusted according to the temperature of the material being discharged. When the temperature is high, the speed can be reduced to extend the time the quartz sand remains in the cooling pipe to lower the temperature of the quartz sand. When the temperature is low, the speed can be increased to speed up the discharge.

[0007] As a further solution of the present invention, the bottom of the cylindrical cooling box is in the shape of a cone with a larger top and a smaller bottom, and the lower surface of the cone is seamlessly connected to the cooling pipe. Through the seamless connection between the cylindrical cooling box and the cooling pipe, two-stage cooling of the quartz sand can be achieved.

[0008] As a further embodiment of the present invention, the stirring device includes a second rotating shaft and a stirring paddle, the stirring paddle being mounted on the second rotating shaft, which is arranged along the central axis of the cylindrical cooling box. A second drive motor is mounted on the cover plate, and one end of the second rotating shaft is connected to an output end of the second drive motor. The stirring device can achieve stirring, heat dissipation, and cooling of the quartz sand within the cylindrical cooling box.

[0009] As a further solution of the present invention, the cover plate is provided with an exhaust hole which is connected to an external exhaust device to timely discharge or recover the hot air in the cylindrical cooling box, thereby accelerating the cooling of the quartz sand.

[0010] As a further embodiment of the present invention, the outer walls of the cylindrical cooling box and the cooling pipe are fixedly provided with a connecting interlayer channel. A cooling medium is provided within the interlayer channel and is connected to an external cooling device. Cooling water is provided within the interlayer channel and connected to an external circulating refrigeration system to achieve internal cooling of the cylindrical cooling box and the cooling pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Interlayer channels are provided on the outer walls of the cylindrical cooling box and the cooling pipe. The cooling water in the interlayer channels is circulated and cooled in conjunction with an external circulating refrigeration system. This allows the quartz sand to be pre-cooled in the cylindrical cooling box in conjunction with the stirring device before entering the cooling pipe for secondary cooling. The discharge speed of the quartz sand in the cooling pipe can be adjusted based on the temperature at the time of discharge. When the temperature is high, the speed can be reduced, and the time the quartz sand spends in the cooling pipe can be extended to lower the temperature of the quartz sand. When the temperature is low, the speed can be increased to speed up the discharge. The cooling pipe has a microchannel structure that can accelerate the cooling rate of the quartz sand and improve cooling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The first rotating shaft 11 is arranged along the central axis of the cooling pipe 4. One end of the first rotating shaft 11 is connected to the output end of the first drive motor 5. The arrangement of the conveying device can not only prevent the cooling pipe 4 from being blocked, but also adjust the discharge speed according to the temperature at the time of discharge. When the temperature is high, the speed can be reduced to extend the time that the quartz sand stays in the cooling pipe 4 to reduce the temperature of the quartz sand. When the temperature is low, the speed can be increased to speed up the discharge.

[0021] The bottom of the cylindrical cooling box 1 is in a cone shape with a larger top and a smaller bottom, and the lower surface of the cone is seamlessly connected to the cooling pipe 4.

One end of the second rotating shaft 13 is connected to the output end of the second drive motor 8. The arrangement of the stirring device can achieve stirring, heat dissipation and cooling of the quartz sand in the cylindrical cooling box 1.

[0023] The cover plate 2 is provided with an exhaust hole 7. The exhaust hole 7 on the cover plate 2 is connected to an external air extraction device to timely discharge or recycle the hot air in the cylindrical cooling box 1 to accelerate the cooling of the quartz sand.
