Technical Field
[0001] This utility model relates to the field of lubricating oil technology, specifically to a filtration device for dipentaerythritol chain oil. Background Technology
[0002] Dipentaerythritol ester chain oil is a chain oil made from dipentaerythritol ester as the base oil. Dipentaerythritol ester is made by reacting dipentaerythritol with organic acids and then undergoing a special post-processing process. It can be used in the chain drive systems of heat setting machines, resin finishing machines and other equipment in industries such as plastic products, metallurgical machinery, and food processing, as well as some chain equipment in high-temperature drying ovens, to provide them with reliable lubrication and protection.
[0003] The crude product from dipentaerythritol ester chain oil requires filtration. However, the dipentaerythritol ester produced has a high viscosity at room temperature, making it difficult to filter. At high temperatures (such as 80°C), the viscosity of dipentaerythritol ester decreases, making it easier to filter. However, at excessively high temperatures, impurities in the crude product, such as unreacted organic acids, are more likely to volatilize and are harmful to the human body. Therefore, we have proposed a filtration device for dipentaerythritol ester chain oil. Utility Model Content
