[0002] Trimethylolpropane (TMP), a key fine chemical product and a common chain extender in the resin industry, has a wide range of applications, including alkyd resins, polyurethanes, unsaturated resins, polyester resins, and coatings. It is also used in the synthesis of aviation lubricants, plasticizers, surfactants, explosives, printing inks, and as a textile auxiliaries and heat stabilizer for polyvinyl chloride resins. In China, TMP is produced primarily through the sodium and calcium methods. In TMP production processes using calcium hydroxide as a catalyst, the condensation reaction produces a large amount of calcium slag, which contains a large amount of water. To reduce its moisture content and facilitate subsequent processing, a dehydration device is typically used for dehydration.

[0003] After searching, the authorization announcement number CN221815444U is a calcium-based trimethylolpropane dehydration device, whose structure includes a mounting base and a liquid recovery tank. A dehydration component for removing moisture from the calcium slag is provided on the upper surface of the mounting base and located on the side of the collection hopper. A conveying component for conveying and squeezing out impurities is provided on the upper surface of the mounting base and located on the side of the dehydration component. The dehydration component includes a press and a liquid guide plate. The outer arc surface of the press is provided with several groups of dehydration holes. The liquid guide plate is provided above the side of the liquid recovery tank away from the collection hopper. By placing the calcium slag into the collection hopper, the auger brings the calcium slag into the press for dehydration.
