[0022] Compared with the related art, the cooling device for anhydrous sodium sulfate provided by the present invention has the following beneficial effects:

[0023] The utility model provides a cooling device for anhydrous sodium sulfate. By arranging a cooling mechanism, a spiral cooling slide extends the sliding time of the material in the slide, so that the material can fully exchange heat with the low-temperature slide wall, thereby achieving a fast and efficient cooling effect. Since the slides are longitudinally staggered, the material can continuously change direction during the sliding process, which is conducive to heat exchange between the materials, making the cooling more uniform and avoiding local overheating or overcooling. The cooling slide can also effectively prevent the material from agglomerating during the cooling process, because the material is continuously rubbed and stirred by the slide wall during the sliding process, thereby maintaining a good dispersion state.

[0024] The utility model provides a cooling device for anhydrous sodium sulfate, which adopts a mixing mechanism. The spiral shape of the fan blades and the rotational movement of the second rotating rod can fully stir and mix the materials in the hopper, so that the temperature between the materials is more uniform, and the quality difference caused by the temperature gradient is avoided. Through the stirring action of the mixing mechanism, the agglomeration or agglomeration that may exist in the materials can be further broken, so that the particle size of the final product is more uniform and the quality is higher.

[0030] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which typical embodiments of the present invention are shown.

[0031] like Figures 1-4 As shown, a cooling device for anhydrous sodium sulfate of the present invention includes a main body 1, a cooling mechanism 6 and a mixing mechanism 7. The cooling mechanism 6 includes a first feeding trough 601 and a second feeding trough 602. The bottoms of the first feeding trough 601 and the second feeding trough 602 are respectively connected to a first cooling chute 603 and a second cooling chute 604. The bottoms of the first cooling chute 603 and the second cooling chute 604 are connected to a first feeding pipe 605 and a second feeding pipe 606.

[0032] The mixing mechanism 7 includes a motor 701, the output end of the motor 701 is connected to the first gear 702 through a connecting rod, the first gear 702 is connected to the first rotating rod 703 through the second gear 704, the first rotating rod 703 is provided with a third gear 705, the third gear 705 is connected to the second rotating rod 707 through the fourth gear 706, the second rotating rod 707 is provided with a fan blade 708, and the outer side of the second rotating rod 707 is provided with a shell 709. The double drop pipe ensures that the cooled material can be discharged in an orderly and rapid manner, avoids the accumulation and blockage of the material in the device, and improves the continuous operation capacity of the device. The mixing mechanism 7 is driven by the motor 701 with high transmission efficiency and is easy to adjust and control, providing strong power support for the mixing of materials.

[0033] like Figure 2 、 Figure 4 As shown, the first cooling chute 603 and the second cooling chute 604 are both spirally arranged, and the first cooling chute 603 and the second cooling chute 604 are longitudinally staggered. The spiral shape of the first cooling chute 603 and the second cooling chute 604 increases the sliding path and residence time of the material in the chute. The spiral chute enables the material to continuously roll and stir during the sliding process. This dynamic motion state helps to accelerate the transfer and dissipation of heat.

[0034] like Figure 1 As shown, a water inlet pipe 2 is provided on one side of the main body 1, and a drain pipe 3 is provided on the other side of the main body 1. The setting of the water inlet pipe 2 allows cooling water to easily enter the interior of the main body 1 to provide necessary cooling conditions for anhydrous sodium sulfate. The setting of the drain pipe 3 is used to discharge the used cooling water from the main body 1.

[0035] like Figure 1 As shown, a feed port 4 is provided at the top of the main body 1, and a drop hopper 5 is provided at the bottom of the first drop pipe 605 and the second drop pipe 606. The feed port 4 provided at the top of the main body 1 enables the material to be conveniently added to the cooling device from above. The setting of the first drop pipe 605 and the second drop pipe 606 realizes the diversion of the material and improves the cooling efficiency of the material.

[0036] like Figure 1As shown, the hopper 5 is conically shaped, and a discharge port 8 is provided at the bottom of the hopper 5. The hopper 5 is conically shaped, and this shape allows the material to naturally concentrate at the bottom of the hopper and smoothly converge to the discharge port 8. The conical hopper 5 also helps to improve the mixing effect. When the fan blades 708 of the mixing mechanism 7 rotate in the hopper, the conical shape enables the material to be stirred and mixed more easily.

[0037] like Figure 2 As shown, the fan blades 708 are arranged in a spiral shape, and the second rotating rod 707 is arranged along the central axis of the hopper 5. The fan blades 708 are arranged in a spiral shape. When the second rotating rod 707 rotates, the fan blades can produce strong stirring and mixing effects. The second rotating rod 707 is arranged along the central axis of the hopper 5, so that the fan blades 708 can evenly cover the internal space of the hopper.

[0038] like Figure 2 As shown, the first discharge chute 601, the second discharge chute 602 and the first drop pipe 605, the second drop pipe 606 are all symmetrically arranged along the central axis of the main body 1. The first discharge chute 601 and the second discharge chute 602 are symmetrically arranged along the central axis of the main body 1 to ensure that the material entering from the feed port 4 can be evenly distributed to the two discharge chutes. The symmetrical arrangement of the first drop pipe 605 and the second drop pipe 606 ensures that the material sliding down from the cooling slide can smoothly enter the drop hopper 5.

[0039] During implementation, the anhydrous sodium sulfate after high-temperature drying is evenly fed into the cooling device through the feed port 4. The material first falls into the first feeding trough 601 and the second feeding trough 602. The material spirally slides down along the first cooling slide 603 and the second cooling slide 604 in the first feeding trough 601 and the second feeding trough 602 respectively. The cooling water in the main body 1 makes the material fully contact with the cooling slide wall during the sliding process, thereby achieving effective cooling. When the first gear 702 rotates, the first rotating rod 703 is driven to rotate through the second gear 704, and then the second rotating rod 707 is driven to rotate through the third gear 705 and the fourth gear 706. The fan blades 708 on the second rotating rod 707 are spirally arranged. As the second rotating rod 707 rotates, the fan blades stir and mix the material in the hopper 5 to ensure that the material is evenly cooled. The valve of the discharge port 8 is opened to discharge the cooled anhydrous sodium sulfate from the hopper 5 for bagging or further processing.

[0040] The advantages of this technical solution in practical applications include but are not limited to the following:

[0041] 1. Cooling mechanism: The spiral cooling slide extends the sliding time of the material in the slide, allowing the material to fully exchange heat with the low-temperature slide wall, thereby achieving a fast and efficient cooling effect;

[0042] 2. Mixing mechanism: the spiral shape of the fan blades and the rotation of the second rotating rod can fully stir and mix the materials in the hopper.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
