Description

Technical Field

[0001] The utility model relates to the technical field of degassing equipment, in particular to a vacuum degassing device for producing waterproof and breathable membranes. Background Art

[0002] A waterproof and breathable membrane is a functional polymer material that blocks liquid water penetration while effectively transmitting water vapor. However, after the membrane material is melted, the various materials need to be stirred and mixed, resulting in a large number of bubbles within the melt. Therefore, vacuum degassing is necessary to eliminate these bubbles. Vacuum degassing is a process that removes bubbles from the material under a vacuum environment. Under vacuum conditions, the molten material is stirred to remove air or other gases. Air or other gases escape from the liquid under vacuum, while mechanical agitation helps the bubbles aggregate and accelerate their detachment from the liquid surface. The vacuum environment reduces the solubility of gases in the liquid, making them easier to escape.

[0003] Although the deaeration device in the prior art has many benefits, it lacks a material turning structure, which causes the material to move inside the deaeration device due to centrifugal force when being stirred, but also makes it difficult for the material located at the bottom of the deaeration device to float up, affecting the floating efficiency of the bubbles and thus affecting the bubble elimination efficiency.

[0014] By adopting the above technical solution, the adsorption force generated by the magnetic force between the first magnet body and the second magnet body ensures the position stability of the second magnet body inside the movable groove and ensures that the rotating shaft can drive the connecting rod to rotate.

[0015] Specifically, an electric push rod is installed on one side of the lower end of the inner wall of the shell, and the upper end of the electric push rod is rotatably linked to the outer wall of the lower end of the connecting plate.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model describes a vacuum degassing device for the production of waterproof and breathable membranes, comprising a shell 1, a rotating shaft 2 and a second magnet body 3. The rotating shaft 2 is rotatably mounted on one side of the upper end of the inner wall of the shell 1, and a movable groove 22 is provided on the outer wall of the lower end of the rotating shaft 2. The second magnet body 3 is arranged inside the movable groove 22, and a connecting rod 31 is installed on the outer wall of the lower end of the second magnet body 3. A connecting disk 32 is installed on the outer wall of the lower end of the connecting rod 31, a connecting ring 33 is installed on the outer wall of the connecting disk 32, and a flipping plate 34 distributed in a circular array is installed on the outer wall of the connecting ring 33.

[0030] When in use, the magnetic attraction between the first magnet body 23 and the second magnet body 3 enables the rotating shaft 2 to drive the second magnet body 3, the connecting rod 31 and the connecting disk 32 to rotate in a circle, thereby driving the connecting disk 32 and the flipping plate 34 to rotate, and the arc shape of the flipping plate 34 drives the molten material to move, so that the molten material at the lower end of the shell 1 moves upward.

[0031] For loading and unloading, for example, Figure 2 As shown, a feed pipe 11 is installed on one side of the outer wall of the upper end of the shell 1, and a discharge pipe 15 is installed on one side of the outer wall of the lower end of the shell 1. The feed pipe 11 and the discharge pipe 15 are both connected to the interior of the shell 1, and a heating device is provided on the inner wall of the shell 1.

[0032] During use, the material enters the shell 1 through the feed pipe 11, and the heating device heats and melts the material, so that the material is in a molten state inside the shell 1, and the degassed material is discharged through the discharge pipe 15 to ensure the smoothness of the material in and out.

[0033] In order to adjust the internal pressure of the housing 1, for example, Figure 2 As shown, connecting pipes 12 are installed on both sides of the outer wall of the upper end of the shell 1, and the two connecting pipes 12 are respectively installed with an air intake pipe 13 and an air exhaust pipe 14.

[0034] When in use, the air inlet pipe 13 is connected to an external air pump, which can transport gas to the inside of the shell 1, maintain the air pressure inside the shell 1 stable, and ensure the smoothness of material discharge inside the shell 1. The air exhaust pipe 14 is connected to an external vacuum pump, which can discharge the gas inside the shell 1 and put the inside of the shell 1 into a vacuum state.

[0035] In order to stir the materials, for example, Figure 2 As shown, the outer wall of the rotating shaft 2 is installed with stirring rods 21 distributed in a circular array. The stirring rods 21 are located inside the outer shell 1 and do not contact the inner wall of the outer shell 1. A motor is provided on the outer wall of the upper end of the rotating shaft 2, and the motor is connected to the outer wall of the upper end of the outer shell 1.

[0036] When in use, the motor drives the rotating shaft 2 to rotate in a circular motion, so that the stirring rod 21 stirs the molten material inside the shell 1, helps bubbles to gather and assists bubbles to separate from the molten material.

[0037] In order to drive the connection disk 32 to rotate, for example, Figure 3 As shown, the inner wall of the movable groove 22 is embedded with a first magnet body 23 distributed in a circular array, and the first magnet body 23 is attracted to the second magnet body 3 .

[0038] During use, the magnetic force between the first magnet body 23 and the second magnet body 3 generates an adsorption force, which ensures the position stability of the second magnet body 3 inside the movable groove 22 and ensures that the shaft 2 can drive the connecting rod 31 to rotate.

[0039] In order to control the rotation of the connecting disk 32, for example, Figure 3 As shown, an electric push rod 16 is installed on one side of the lower end of the inner wall of the shell 1, and the upper end of the electric push rod 16 is rotatably connected to the outer wall of the lower end of the connecting plate 32.

[0040] When in use, the electric push rod 16 can push the connecting disk 32 to move vertically, thereby adjusting the use height of the flip plate 34 inside the shell 1. The flip plate 34 can flip and move the material inside the shell 1, and the electric push rod 16 can rotate relative to the connecting disk 32 to keep the position of the electric push rod 16 stable.

[0041] For turning the material, for example, Figure 4 As shown, the turning plate 34 is designed in an arc shape, and the turning plate 34 does not contact the inner wall of the shell 1.

[0042] When in use, the turning plate 34 is driven by the connecting rod 31 and the connecting disk 32 to rotate in a circle, so that the turning plate 34 can drive the molten material inside the shell 1 to move, so that the material at the lower end of the shell 1 moves upward, thereby turning the molten material.

[0043] When the utility model is in use, the material enters the interior of the housing 1 through the feed pipe 11, and the heating device adjusts the temperature of the material inside the housing 1 to keep the material in a molten state;

[0044] The motor drives the rotating shaft 2 and the stirring rod 21 to rotate in a circular motion, thereby stirring the material inside the housing 1, helping bubbles to gather and separate from the molten material;

[0045] The external vacuum pump extracts and evacuates the interior of the housing 1 through the exhaust pipe 14 and the connecting pipe 12, keeping the interior of the housing 1 in a vacuum state, reducing the solubility of the gas in the liquid, and promoting the escape of bubbles from the molten material.

[0046] The electric push rod 16 pushes the connecting plate 32 to move vertically, so that the second magnet body 3 moves between the first magnet body 23. Through the magnetic attraction between the first magnet body 23 and the second magnet body 3, the rotating shaft 2 can drive the second magnet body 3, the connecting rod 31 and the connecting plate 32 to rotate in a circle, thereby driving the connecting plate 32 and the flipping plate 34 to rotate;

[0047] When the flipping plate 34 rotates, the arc shape of the flipping plate 34 drives the molten material to move, causing the molten material at the lower end of the shell 1 to move upward, thereby achieving the purpose of flipping the material inside the shell 1, helping the molten material at the lower end to move upward with the bubbles, and assisting the bubbles to move to the upper end of the liquid surface.
