Description

Technical Field

[0001] The utility model relates to the technical field of silicone oil production and processing, in particular to an integrated safety explosion-proof vacuum tank. Background Art

[0002] Silicone oil usually refers to linear polysiloxane products that remain liquid at room temperature. They are generally divided into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil is methyl silicone oil, also known as ordinary silicone oil. All of its organic groups are methyl. Methyl silicone oil has good chemical stability, insulation, and good hydrophobic properties. It is produced by hydrolyzing dimethyldichlorosilane with water to obtain a primary polycondensation ring body. The ring body is cracked and distilled to obtain a low-ring body. Then, the ring body, capping agent, and catalyst are put together for polymerization to obtain a mixture of various polymerization degrees. Silicone oil can be obtained by removing low-boiling substances through reduced pressure distillation. During the production process of silicone oil, storage equipment is required to store the silicone oil.

[0003] A silicone oil storage barrel with authorization announcement number CN205633328U includes a barrel body, an opening at the top of the barrel body, a cover body on the opening, an annular first flange at the edge of the upper surface of the cover body, a frustum on the lower surface of the cover body, the diameter of the frustum gradually decreases from top to bottom, and an annular slope matching the shape of the frustum is provided at the opening. The purpose of this utility model is to provide a silicone oil storage barrel with high cover strength and capable of multi-layer storage.

[0004] Although the cover of this device is strong and can store multiple layers, it cannot create a vacuum environment in the barrel. In addition, the device does not have a stirring function and cannot prevent the silicone oil from stratifying after being placed for a long time. In addition, the device cannot scrape off the silicone oil adhering to the barrel wall. In view of this, we propose an integrated safety and explosion-proof vacuum tank. Utility Model Content

[0025] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0026] An integrated safety explosion-proof vacuum tank includes a vacuum tank 1, a top cover 11 is provided on the top of the vacuum tank 1, and a hydraulic cylinder 12 is symmetrically fixedly connected to the outer wall of the vacuum tank 1 near the left and right sides by bolts. The piston rod end of the hydraulic cylinder 12 is fixedly connected to the bottom of the top cover 11 by bolts to drive the top cover 11 to move.

[0027] Specifically, a sealing ring 13 is fixed to the bottom of the top cover 11 by glue to play a sealing role. The sealing ring 13 is made of rubber.

[0028] Furthermore, a vacuum pump 14 is fixedly connected to the top of the top cover 11 near the left side by bolts, and the air inlet of the vacuum pump 14 is connected to a vacuum tube 15. The bottom end of the vacuum tube 15 passes through the bottom of the top cover 11 and passes into the inner cavity of the vacuum tank 1, which is used to extract the air in the vacuum tank 1.

[0029] It should be added that a pressure gauge 16 is fixedly connected to the top of the top cover 11 near the right side by bolts. The detection head of the pressure gauge 16 passes through the bottom of the top cover 11 and extends into the inner cavity of the vacuum tank 1 to monitor the air pressure in the vacuum tank 1.

[0030] As a preference of this embodiment, a stirring mechanism 2 is provided in the vacuum tank 1 , and the stirring mechanism 2 includes a rotating motor 21 . The rotating motor 21 is fixedly connected to the bottom of the top cover 11 by bolts to drive the outer shell 22 to rotate.

[0031] Specifically, the output shaft of the rotary motor 21 is coaxially connected to the housing 22 , and the inner wall of the housing 22 is fixedly connected to the limiting ring 23 by bolts to limit the highest position of the slider 27 .

[0032] Specifically, a driving motor 24 is fixedly connected to the top of the inner wall of the shell 22 by bolts to drive the reciprocating screw 25 to rotate. The output shaft of the driving motor 24 is coaxially connected to the reciprocating screw 25 to drive the slider 27 to reciprocate up and down.

[0033] Specifically, the bottom end of the reciprocating screw 25 is fixedly connected to the limit plate 26 by bolts to limit the lowest position of the slider 27. The reciprocating screw 25 is threadedly connected to the slider 27, and the slider 27 is slidably connected to the inner wall of the shell 22 to drive the connecting rod 28 to move.

[0034] Specifically, the bottom of the slider 27 near the left and right sides is symmetrically fixed with connecting rods 28 by bolts. The bottom end of the connecting rod 28 passes through the bottom of the shell 22 and is slidably connected to the shell 22 to drive the L-shaped mounting plate 29 to move.

[0035] Specifically, the bottom end of the connecting rod 28 is fixedly connected to an L-shaped mounting plate 29 by bolts, which is used to drive the stirring rod 291 to move. The outer surface of the L-shaped mounting plate 29 is fixedly connected to a plurality of stirring rods 291 by bolts. The stirring rods 291 are evenly spaced and are used to stir the silicone oil.

[0036] Specifically, one end of the stirring rod 291 is fixedly connected to the arc scraper 292 by bolts. The outer wall of the arc scraper 292 is in contact with the inner wall of the vacuum tank 1 to scrape off the silicone oil adhering to the inner wall of the vacuum tank 1.

[0037] It is worth mentioning that the structures and working principles of the vacuum pump 14 and the pressure gauge 16 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0038] During specific use, when the silicone oil inside the vacuum tank 1 needs to be stirred, the user first turns on the rotating motor 21, which drives the outer shell 22 to rotate, thereby driving the drive motor 24 to rotate, thereby driving the reciprocating screw 25 to rotate, thereby driving the slider 27 to rotate, thereby driving the two connecting rods 28 to rotate, thereby driving the two L-shaped mounting plates 29 to rotate, thereby driving the stirring rod 291 to rotate and stir the silicone oil, thereby driving the arc-shaped scraper 292 to rotate and scrape off the silicone oil adhering to the inner wall of the vacuum tank 1;

[0039] Turn on the drive motor 24, which drives the reciprocating screw 25 to rotate, thereby driving the slider 27 to move upward, thereby driving the two connecting rods 28 to move upward, thereby driving the two L-shaped mounting plates 29 to move upward, thereby driving the stirring rod 291 to move upward, thereby driving the arc scraper 292 to move upward;

[0040] Until the top of the slider 27 is tightly fitted with the bottom of the limit ring 23, the reciprocating screw 25 reverses, thereby driving the slider 27 to move downward, thereby driving the two connecting rods 28 to move downward, thereby driving the two L-shaped mounting plates 29 to move downward, thereby driving the stirring rod 291 to move downward, thereby driving the arc-shaped scraper 292 to move downward, until the bottom of the slider 27 is fitted with the top of the limit plate 26, the reciprocating screw 25 rotates forward and drives the slider 27 to move upward again;

[0041] During this process, the reciprocating screw 25 drives the slider 27 to reciprocate up and down, thereby driving all the stirring rods 291 and all the curved scrapers 292 to reciprocate up and down. Since all the stirring rods 291 and all the curved scrapers 292 are rotating, they are driven to reciprocate up and down during the rotation process.

[0042] When it is necessary to create a vacuum environment in the vacuum tank 1, the user first turns on the vacuum pump 14. The vacuum pump 14 extracts the air in the vacuum tank 1 through the vacuum tube 15. The air pressure in the vacuum tank 1 can be known by observing the pressure gauge 16. When the air pressure in the vacuum tank 1 is lower than one atmosphere, the internal environment of the vacuum tank 1 is in a vacuum state.

[0043] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
