Description

Technical Field

[0001] The utility model relates to the technical field of grease storage tanks, in particular to a grease storage tank which can be preheated. Background Art

[0002] Fatty acids, as organic matter, need to be decomposed by fat and then extracted for use. At present, when preparing fatty acids, workers generally use cattle and sheep fat for hydrolysis. Before preparing fatty acids with animal fats, the fats are generally stored in storage tanks. However, if the fats are not preheated before entering the hydrolysis tower, the hydrolysis efficiency is greatly reduced. There are currently two ways to heat. One is to connect a heat exchanger to the back of the storage tank for heating. This structure increases the floor space and cost. The other is to directly set a jacket outside the storage tank. This storage tank is directly heated. This structure can generally only be used for small storage tanks. If large storage tanks do not use all the fat, it will have a certain impact on the fat that has been heated but not discharged. Moreover, most of the existing storage tanks are an integral inner cavity, which causes the fat added after a period of time to be directly mixed with the previous fat, which is not conducive to the storage of fat. Therefore, an improved technology is urgently needed to solve this problem in the prior art. Utility Model Content
