Description

Technical Field

[0001] This utility model relates to the technical field of magnesium sulfate whisker preparation, and in particular to a magnesium sulfate whisker preparation apparatus. Background Technology

[0002] Magnesium sulfate whiskers, also known as basic magnesium sulfate whiskers, magnesium salt whiskers, or magnesium oxysulfate whiskers, are a new type of inorganic flame retardant and fiber reinforcing material. They have a single crystal structure. The preparation of magnesium sulfate whiskers requires preparing solutions of magnesium sulfate and sodium hydroxide separately and adding them to a reaction vessel according to the ratio. After reacting at a certain temperature for a certain time, coarse whiskers are obtained. Then, after fractionation, drying, and other operations, different grades of dry whisker products are obtained.

[0003] Existing magnesium sulfate whisker preparation devices, such as the magnesium sulfate crystallization equipment disclosed in utility model patent application number 202222355351.7, mainly include a fixed cylinder, a fixed box fixedly installed on the top of the fixed cylinder, a liquid inlet pipe installed on one side of the fixed box, a cooling box fixedly installed on the top of the fixed box, multiple cooling pipes installed at the bottom of the cooling box, and a common conversion box installed at the bottom of the multiple cooling pipes. The conversion box is equipped with a water guiding mechanism. In use, the liquid inlet pipe introduces magnesium sulfate liquid into the fixed cylinder, while ice is placed in the cooling box and sealed with a cover plate. Water in the cooling box is introduced into the conversion box through the cooling pipes under the action of gravity, thereby cooling the magnesium sulfate liquid. Then, the motor switch is turned on, and the output shaft of the motor drives the rotating shaft to rotate. The rotating shaft drives the propeller to rotate. The rotating propeller, in cooperation with the water guiding box, leads the water source in the conversion box out through the water inlet and introduces it into the cooling box through the water guiding pipe for circulation. At the same time, the cooled magnesium sulfate crystals are formed.

[0004] However, most existing preparation devices cannot sieve magnesium sulfate whiskers after preparation, resulting in inconsistent quality of magnesium sulfate whiskers. Moreover, the reaction and drying of magnesium sulfate whiskers require a certain amount of time, and most existing preparation devices are relatively inefficient. Utility Model Content

After a certain period of time, the preparation mechanism transports the solution to the sieving mechanism for sieving.
