DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-4As shown, a mixing device for preparing metal anti-rust oil comprises a tank body 1, a jacket 2 is arranged on the outer surface of the tank body 1, two heating ports 3 are arranged on the jacket 2, a discharge port 4 is arranged at the lower end of the tank body 1, a sealing cover 5 is arranged above the tank body 1, a flange 6 is arranged at the upper end of the tank body 1 and the lower end of the sealing cover 5, screws 7 are evenly arranged on the upper end surface of the flange 6 on the tank body 1, through holes matching with the screws 7 are evenly opened on the outer surface of the flange 6 on the sealing cover 5, a nut 8 is threadedly connected to the upper end of the screw 7, a spring 9 is sleeved on the outer surface of the screw 7 and between the flange 6 on the sealing cover 5 and the nut 8, A driving motor 10 is provided at the upper end of the sealing cover 5, and a stirring rod 11 is provided at the output end of the driving motor 10. The stirring rod 11 is located inside the tank body 1. Extension plates 12 are evenly provided on the outer surface of the flange 6 on the tank body 1. A supporting frame 13 is provided on the extension plate 12. A hydraulic cylinder 14 is provided on the supporting frame 13. The output end of the hydraulic cylinder 14 is fixedly connected to the upper end of the sealing cover 5. A feeding port 15 is provided on the sealing cover 5. An exhaust fan 16 is provided on the feeding port 15. An end cover 17 is provided on the exhaust fan 16. The exhaust fan 16 and the feeding port 15 as well as the exhaust fan 16 and the end cover 17 are all rotatably connected.

[0019] The two heating ports 3 on the jacket 2 are symmetrically arranged. An external high-temperature steam device injects high-temperature steam into the jacket 2 through one of the heating ports 3 and discharges it to the outside through the other heating port 3. During the movement of the high-temperature steam in the jacket 2, the base oil in the tank body 1 can be continuously heated to 90-120°C. A condensate discharge outlet is also provided at the bottom of the jacket 2, which is not shown in the drawing and is used to discharge the condensate in the jacket 2.

[0020] The sealing cover 5 and the end cover 17 can seal the upper opening of the tank body 1. When the base oil in the tank body 1 needs to be heated, in order to reduce heat loss and improve heating efficiency, the sealing cover 5 is fitted to the tank body 1 and the feed port 15 is closed by the end cover 17, so that the temperature of the base oil in the tank body 1 can be increased as quickly as possible and the heating efficiency can be improved.

[0021] When the base oil in the tank body 1 reaches the interval temperature, the end cover 17 and the exhaust fan 16 are rotated to open the feeding port 15 on the sealing cover 5, and then additives such as rust inhibitor, co-solvent, antioxidant, etc. are added into the tank body 1 in sequence. After the addition is completed, the feeding port 15 is closed by rotating the end cover 17 and the exhaust fan 16, and the stirring rod 11 is driven by the driving motor 10 to mix the additives and the base oil evenly for subsequent use.

[0022] The addition temperature of the film-forming agent is in the range of 50-80°C. After the additives other than the film-forming agent are completely stirred, the input of high-temperature steam into the jacket 2 is stopped, and the end cover 17 is rotated. Then, the sealing cover 5 is driven to move upward by the movement of the hydraulic cylinder 14, and then the exhaust fan 16 is started to quickly discharge the hot air in the tank body 1 to the outside through the feeding port 15 and the gap between the tank body 1 and the sealing cover 5. At the same time, the stirring rod 11 continues to rotate to accelerate the heat dissipation efficiency of the base oil in the tank body 1. When the base oil in the tank body 1 When the temperature of the oil drops from 90-120°C to 50-80°C, the exhaust fan 16 is turned off and turned on, and the film-forming agent is added into the tank body 1 through the feeding port 15, and then the feeding port 15 is closed by the exhaust fan 16 and the end cover 17, and then the sealing cover 5 is controlled to move downward by the hydraulic cylinder 14 to re-close the tank body 1, and an appropriate amount of high-temperature steam is injected into the jacket 2 through the heating port 3 to keep the temperature in the tank body 1 at 50-80°C, and stirring is continued until the preparation of the rust-proof oil is completed.

[0023] After the preparation of the anti-rust oil is completed, the temperature of the anti-rust oil in the tank body 1 is still high. At this time, the sealing cover 5 can be driven to move upward by the hydraulic cylinder 14, and the hot air in the tank body 1 can be continuously discharged through the exhaust fan 16 by rotating the end cover 17, thereby accelerating the loss of temperature in the tank body 1 and reducing the cooling time for subsequent filling and storage.

[0024] By means of the provided spring 9 and nut 8 , the upper flange 6 and the sealing cover 5 can be tightly pressed against the lower flange 6 and the tank body 1 , so as to quickly open the sealing cover 5 and close the tank body 1 .

[0025] Furthermore, the exhaust fan 16 and the feeding port 15 are connected to the end cover 17 via locking members 18, respectively. The locking members can ensure that the positions of the exhaust fan 16 and the end cover 17 will not change, thereby improving the stability of the exhaust fan 16 and the end cover 17 during production.

[0026] Furthermore, the outer surface of the screw 7 includes a smooth portion and a threaded portion. The outer surface of the smooth portion of the screw 7 is fitted with the inner surface of the through hole at the flange 6 on the sealing cover 5 to improve the smoothness of the fit between the screw 7 and the flange 6.

[0027] Furthermore, it also includes a temperature sensor 19 which is arranged on the sealing cover 5 and extends to the inside of the tank body 1. The temperature sensor 19 is used to detect the temperature of the liquid in the tank body 1, so as to control the production process according to the temperature.

[0028] Furthermore, a discharge pump 20 is installed at the discharge port 4 of the tank body 1. When the temperature of the anti-rust oil in the tank body 1 drops below 25°C, the anti-rust oil can be discharged to the outside through the discharge port 4. Through the set discharge pump 20, the anti-rust oil can be directly pumped into the storage tank, and at the same time, the extraction efficiency of the anti-rust oil can be improved, and the use effect is good.

[0029] The device can quickly discharge the high-temperature gas in the tank body 1 to the outside by lifting the sealing cover 5 and using the exhaust fan 16, and can accelerate the cooling efficiency of the liquid in the tank body 1 and shorten the cooling time through continuous stirring of the stirring rod 11, thereby facilitating subsequent safe filling.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
