[0002] Aviation hydraulic oil is a lubricant used to reduce friction and wear during mechanical movement. Aviation hydraulic oil also needs to have other properties, such as good oxidation resistance and thermal stability, and the ability to be used at extreme temperatures. The preparation of aviation hydraulic oil usually involves the Fischer-Tropsch synthesis reaction, which refers to the process of converting different raw materials (such as hydrocarbon compounds) into finished products under high temperature and high pressure conditions. During the preparation process, the oil barrels need to be cleaned to avoid contamination by dust and other impurities.

A placement through hole 102 is opened on the top of the box body 1, and a groove 1021 is opened on one side of the placement through hole 102. The U-shaped placement plate 3 is located in the box body 1 and has a diameter larger than the placement through hole 102. The oil drum 2 is inverted on the U-shaped placement plate 3. Two water tanks 103 are installed on one side of the inner bottom wall of the box body 1. Liquid supply components 7 are provided in the two water tanks 103. The two water tanks 103 are respectively provided with an inner infusion tube 104 and an outer infusion tube 105. Each water tank 103 is divided into a clean water chamber and a clean liquid chamber by a fixed partition 1031. Each liquid supply assembly 7 includes a water pump 701, and the top of each water pump 701 is connected to an output pipe 702, and each output pipe 702 passes through the top wall of the water tank 103 and is respectively connected to the bottom ends of the inner infusion pipe 104 and the outer infusion pipe 105, and an L-shaped suction pipe 703 is connected to the outer wall of one side of each water pump 701, and the end of each suction pipe 703 passes through the partition 1031 and is located in the cleaning liquid cavity, and the bottom wall of each suction pipe 703 is connected to a first liquid inlet pipe 7031, and the top of the outer wall of each suction pipe 703 is connected to a second liquid inlet pipe 7032, and the first liquid inlet pipe 7031 and the second liquid inlet pipe 7032 are both installed with a control valve 704; The top ends of the external infusion tube 105 and the external brush plate 508 are extended to the outside of the box body 1 through the groove 1021, and the two sides of the outer wall of the internal infusion tube 104 and the outer wall of the external infusion tube 105 close to the oil barrel 2 are connected with a plurality of nozzles. A sealing door 101 is installed on the side of the box body 1 close to the human body, and a lifting protective cover is provided at the top of the box body 1 at the placement through hole 102. The processing mechanism 4 is composed of an adjustment component 5 and a downward moving component 6. The adjustment component 5 is used to clean the oil barrels 2 of different diameters, and the downward moving component 6 is used to control the downward movement of the U-shaped placement plate 3 and control the rotation of the oil barrel 2. The adjustment component 5 includes two electric telescopic cylinders 501, two internal brush plates 507 and two external brush plates 508. The two internal brush plates 507 are symmetrically arranged on both sides of the internal infusion tube 104, and the two external brush plates 508 are symmetrically arranged on both sides of the external infusion tube 105. The two external brush plates 508 and the internal brush plates 507 are connected by a gear rack system. When preparing aviation hydraulic oil through Fischer-Tropsch synthesis products, the oil barrel 2 filled with oil needs to be cleaned. First, the staff puts the oil barrel 2 upside down on the U-shaped placement plate 3, and then starts the downward moving component 6 and the adjusting component 5 in the processing mechanism 4 in sequence through the external controller. The downward moving component 6 controls the U-shaped placement plate 3 to move downward, so that the placed oil barrel 2 moves into the box body 1 through the placement through hole 102 until its inner bottom wall contacts the cleaning brush plate 5071 of the adjusting component 5. At the same time, the structure for driving the oil barrel 2 to rotate in the downward moving component 6 also contacts the outer wall of the oil barrel 2. Then the electric telescopic cylinder 501 of the adjusting component 5 works to push the outer brush plate 508 to move, and then controls the inner brush plate 507 to move through the gear rack system (the driving gear 5041 and the inner gear 506 in the text) to contact the outer wall and inner wall of the oil barrel 2 respectively. At this time, the oil barrel 2 rotates; Then the water pump 701 of the liquid supply component 7 starts to work, and the cleaning liquid is first sent into the inner liquid infusion tube 104 and the outer liquid infusion tube 105 through the second liquid inlet pipe 7032 through the suction pipe 703 and the output pipe 702, and is sprayed from the nozzle to the inner and outer walls of the oil barrel 2, and the rotating oil barrel 2 can ensure comprehensive spraying. At the same time, during the rotation process, the inner brush plate 507 and the outer brush plate 508 clean the wall of the oil barrel 2. After a period of time, the cleaning water is sent into the inner liquid infusion tube 104 and the outer liquid infusion tube 105 through the first liquid inlet pipe 7031 through the suction pipe 703 and the output pipe 702, and sprayed onto the wall of the oil barrel 2 for rinsing. After cleaning, it is dried and then filled with aviation hydraulic oil.

[0035] See also Figure 1-8 As shown, according to the above embodiment, a process for preparing an aviation hydraulic oil production device from a Fischer-Tropsch synthesis product is also provided, comprising the following steps: Step 1, preparation of aviation hydraulic oil, adopting a hydrofining-hydrodecondensation-hydrogenation supplementary refining-precision fractionation process under mild hydrogenation conditions to prepare an aviation hydraulic oil base oil containing an appropriate amount of aromatics, heating the base oil to 80-90°C, adding various additives in sequence and stirring for 2 hours, and maintaining 80-90°C for warming to obtain a semi-finished hydraulic oil, then cooling the semi-finished hydraulic oil after warming to 70-75°C, vacuum filtering, and naturally cooling to room temperature to obtain a finished hydraulic oil; This step is a prior art, and the raw material can be atypical cycloalkane wax oil, which has a distillation range of 250-360°C, a pour point of -3 to 3°C, a sulfur content of 2 to 2.5%, an aromatic content of 20 to 25%, cycloalkanes of 33 to 40 wt%, and paraffins of 10 to 12 wt%; The product yield obtained by this preparation method is greater than 90%, the aromatic content is 7-10%, the pour point is less than -85°C, the cycloalkane content is greater than 85%, and the sulfur content is less than 5ppm.

[0036] Step 2: placing the oil barrel. When the finished hydraulic oil is obtained, the oil barrel 2 is inverted on the U-shaped placement plate 3, and then the downward moving component 6 in the processing mechanism 4 is started.

Finally, the water pump 701 works to first spray the cleaning liquid onto the wall of the oil barrel 2 through the second liquid inlet pipe 7032, and cooperate with the friction wheel 6082 to drive the oil barrel 2 to rotate to complete the cleaning. Then, the cleaning water is sprayed onto the oil barrel 2 through the first liquid inlet pipe 7031. After cleaning, it is dried and then filled with aviation hydraulic oil.
