Description

Technical Field

[0001] This invention relates to an apparatus for producing ethylene bis-stearamide, and more particularly to a refining production line and process for ethylene bis-stearamide. Background Technology

[0002] The production process of ethylene bis-stearamide is as follows: Prepare raw materials, including ethylene amine and stearamide; mix ethylene amine and stearamide together and feed them into a reaction vessel; add a small amount of acidic catalyst (such as copper sulfate or sodium sulfate); heat the mixture in the reaction vessel to the reaction temperature (usually 60-80℃) and maintain the reaction time for 3-5 hours; discharge the mixture from the reaction vessel after the reaction is complete, wash and dry it to obtain the finished product. Currently, the preparation of ethylene bis-stearamide using a reaction vessel is a mature process, but the ethylene bis-stearamide produced by the reaction vessel is a mixture and requires refining. The current production of ethylene bis-stearamide requires a lot of independent equipment, and the loading and unloading of each piece of equipment requires manpower and resources, which significantly affects production efficiency and costs. Summary of the Invention

The bottom of the receiving hopper is in contact with the upper surface of the conveyor belt, and a discharge notch is provided on the bottom of the receiving hopper on the side away from the conveyor belt.

[0008] The production process includes:

[0009] S1. Pour all the mixture after the chemical reaction in the reactor into the cleaning tank, add clean water into the cleaning tank and control the stirrer to rotate and stir. After stirring for a period of time, stop the stirrer and let it stand for a period of time. After draining the upper wastewater, add clean water again and repeat the above steps at least twice. Finally, obtain a cleaned mixture of ethylene bis-stearamide and water. Turn on the stirrer again and open the discharge port to discharge the ethylene bis-stearamide fluid.

[0010] S2 guides the ethylene bis-stearamide fluid discharged from S1 to the filtration equipment for filtration, and removes excess water;

[0011] S3, pour the wet ethylene bis-stearamide granules obtained in S2 onto the drying platform of the primary drying equipment, heat the drying platform with the electric heating element, and after the predetermined time is reached, the tilting table is tilted downward to pour out the ethylene bis-stearamide granules on it.

[0012] S4. Pour the ethylene bis-stearamide granules obtained in S3 into the receiving hopper. The ethylene bis-stearamide granules in the receiving hopper are output from the discharge gap along the conveyor belt, heated by the thermal radiation heating component, and then output from the conveyor belt.

Primary drying equipment; 3. The moist ethylene bis-stearamide granules are gradually heated by the drying platform and roughly dried. The tilting table tilts downward to pour out the ethylene bis-stearamide granules; 4. The receiving hopper is used to receive the preliminarily dried ethylene bis-stearamide granules and output them from the discharge gap along the conveyor belt. After being heated by the thermal radiation heating component, they are output from the conveyor belt.
