Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a lubricating oil fine filtering and purification device. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

[0003] However, during the use of lubricating oil, it is inevitable that various dust, debris and mechanical impurities will be mixed in. In order to ensure the reuse of lubricating oil, the waste lubricating oil needs to be filtered, washed, pickled and purified before being put into use again. However, since some chemical impurities will be mixed in the lubricating oil during the washing and pickling process, affecting its use, further fine filtration and purification is required to remove gas impurities and chemical components in the lubricating oil. In addition, since the lubricating oil will become dense after cooling for a period of time, the lubricating oil will accumulate during the feeding process, affecting the feeding effect.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] A lubricating oil fine filtration and purification device, such as Figure 1 As shown, it includes a filter adsorption box 1, a feed pipe 2 and an evaporation tank 8. The feed pipe 2 is arranged on one side of the top of the filter adsorption box 1 and is connected to the filter adsorption box 1. The filter adsorption box 1 is connected to the evaporation tank 8 through an oil pipeline 7.

[0016] The end of the feed pipe 8 is connected to an oil inlet 3, and a conveying screw 15 is installed inside the feed pipe 8. One end of the conveying screw 15 is connected to a rotating motor 17 outside the feed pipe 8, and is used to deliver the lubricating oil after preliminary filtration into the filter adsorption box 1 for re-filtration.

[0017] A preheating rod 16 is installed inside the conveying screw 15 located inside the feed pipe 8, which can preheat the lubricating oil through the heat conduction effect of the conveying screw 15 to prevent the lubricating oil from becoming thick due to cooling and being difficult to convey to the filter adsorption box 1.

[0018] An activated carbon adsorption layer 4, a filter membrane cloth 5, and an oil collecting layer 6 are arranged in sequence from top to bottom inside the filter adsorption box 1. The activated carbon adsorption layer 4 can adsorb some impurities in the lubricating oil that cannot be physically filtered through activated carbon particles, and the filter membrane cloth 5 can prevent the activated carbon particles from flowing into the oil collecting layer below along with the lubricating oil.

[0019] The oil collecting layer 6 is communicated with the oil delivery pipe 7 to facilitate the delivery of the filtered lubricating oil, and the oil delivery pipe 7 is provided with an oil delivery pump.

[0020] A heating plate 9 is installed at the bottom of the evaporation tank 8, and an adjustable valve 10 is installed at the center of the heating plate 9 to facilitate the lubricating oil after evaporation and purification to be sent out from the oil outlet 11 at the bottom.

[0021] A stirring rod 12 is installed inside the evaporation tank 8 to stir the lubricating oil so that it is heated evenly. The top end of the stirring rod 12 passes through the evaporation tank 8 upward and is connected to a driving motor 13 at the top.

[0022] The top of the evaporation tank 8 is connected to an exhaust port 14, and the evaporated water vapor and other impurity gases are discharged from the exhaust port to be separated from the lubricating oil.

[0023] In order to prevent the exhausted gas impurities from flowing back into the evaporation tank 8 , a one-way valve is provided on the exhaust port 14 .

[0024] When in use, firstly, the preheating rod 16 is started for preheating, so that the conveying screw 15 can conduct heat through its own thermal conductivity, and then lubricating oil is conveyed into the feed pipe and the conveying screw is started for conveying.

[0025] After the lubricating oil enters the filter adsorption box 1, the lubricating oil first reacts with the activated carbon particles in the activated carbon adsorption layer to remove some impurities. Then, the reacted lubricating oil moves downward through the filter membrane cloth to be filtered again and enters the oil collecting layer, while preventing the activated carbon particles from passing through.

[0026] The lubricating oil in the oil collecting layer is sent to the evaporation tank through the oil pipeline for evaporation and purification. The lubricating oil is stirred by the stirring rod 12 so that the lubricating oil can be evenly heated. The evaporated gas impurities are discharged through the exhaust port. After evaporation is completed, the valve 10 is opened to discharge the lubricating oil from the oil outlet.

[0027] The utility model provides a lubricating oil fine filtering and purification device with a simple structure and convenient operation. The lubricating oil is filtered by a preheating rod to make the lubricating oil thinner, thereby avoiding lubricating oil accumulation and improving the feeding speed. The lubricating oil is filtered again by a filtering adsorption box, which can adsorb the color and odor in the lubricating oil on the one hand and preliminarily adsorb harmful substances in the lubricating oil on the other hand. The impurities in the lubricating oil are evaporated and purified by an evaporating tank and then discharged through an exhaust port, thereby effectively improving the purification efficiency and ensuring the purity of the lubricating oil.
