Description

Technical Field

[0001] This utility model belongs to the field of kaolin technology, and in particular relates to a water-cooling device for calcined kaolin. Background Technology

[0002] Kaolin is one of the world's four major non-metallic minerals. It is a type of clay and clay rock mainly composed of kaolinite group clay minerals. It is widely distributed in my country, spanning both northern and southern regions, but its reserves are relatively concentrated, with the southern region having the largest reserves. Kaolinite group clay minerals are formed in acidic media lacking alkali and alkaline earth metals, through the weathering of feldspar or other silicate minerals in igneous and metamorphic rocks. Kaolin boasts excellent properties and a wide range of applications. It possesses advantages such as high whiteness, fine particle size, strong covering power, rapid adsorption, good acid and alkali resistance, and stable physicochemical properties. Processed kaolin products are widely used in various industries including papermaking, architectural coatings, plastics, high-grade ceramics, and petrochemicals. During the calcination process, the temperature of the kaolin powder rises significantly, and the high-temperature powder requires rapid cooling during transportation to prevent quality degradation and equipment damage. Chinese utility model CN ​​209399779 U discloses a cooling device for calcining kaolin clinker. The air cooler includes a cooling chamber fixed on a support frame, the cooling chamber comprising upper and lower perforated plates, a cooling conveying pipe, an air inlet, an air outlet, and several air duct partitions with interconnected air duct openings arranged vertically and alternately. The air outlet is located in the upper part of the cooling chamber, and the air inlet is located in the lower part of the cooling chamber. The cooling conveying pipe extends from the upper perforated plate to the lower perforated plate, connecting the feed chamber and the discharge hopper. The above-mentioned cooling device is complex, occupies a large space, and has poor cooling uniformity, resulting in high energy consumption, low efficiency, and high noise. Summary of the Invention

[0003] The technical problem solved by this utility model is that the existing cooling devices for conveying and cooling kaolin powder are complex, occupy a large space, and have poor cooling uniformity, resulting in high energy consumption, low efficiency, and high noise.

The conveying pipeline passes through the water bath. The cooling circulation assembly includes a cooling tower and a cooling water tank. The cooling water tank contains a hot water pool and a cold water pool. The hot water pool inlet pipe is connected to the outlet of the water bath, the hot water pool outlet pipe is connected to the cooling tower, the cooling tower outlet pipe is connected to the cold water pool, and the cold water pool outlet pipe is connected to the inlet of the water bath via a circulating water pump and a solenoid valve. The temperature control assembly includes temperature sensors respectively installed at the inlet and outlet of the conveying pipeline, inside the water bath, and inside the cooling water tank, and a controller. The controller input is electrically connected to the temperature sensors at the inlet and outlet of the conveying pipeline, inside the water bath, and inside the cooling water tank, and the controller output is electrically connected to the circulating water pump and the solenoid valve, respectively.

[0005] Furthermore, the water bath is a rectangular tank, and multiple overflow ports are evenly spaced at the upper end of one side wall of the water bath.
