Description

Technical Field

[0001] The invention relates to the technical field of silicone oil production, in particular to a silicone oil preparation device. Background Art

[0002] Silicone oil usually refers to linear polysiloxane products that remain in liquid state at room temperature. It is 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. The reactor is the main container for producing silicone oil.

[0003] At present, when the materials used in silicone oil production are introduced into the reactor in sequence on the market, the materials are often in a stratified state due to different material densities and materials. During stirring, the reactor will drive several stirring rods to rotate rapidly in the horizontal direction to stir the materials. Since the materials are in a stratified state and the stirring rods rotate in the horizontal direction, the top and bottom areas of the reactor and the edge areas need to be stirred for a long time to be fully mixed, resulting in low production efficiency, which affects production efficiency.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a silicone oil preparation device, which has the following beneficial effects:

[0020] 1. The silicone oil preparation device drives the spiral stirring rod to rotate through a charged wireless motor, and at the same time combines the up and down swing of the stirring component on the corrugated fixed cylinder to achieve all-round and three-dimensional mixing of the silicone oil raw materials in the reactor, avoiding the mixing dead corners in the traditional stirring method, especially the top and bottom areas of the reactor, as well as the edge areas, which easily lead to uneven mixing of the silicone oil raw materials. This movement mode not only covers the upper and lower spaces and the radius space, but also takes into account the mixing of the inner circle and the outer circle, ensuring the uniform mixing of the silicone oil raw materials.

[0021] 2. The silicone oil preparation device can swing up and down in the support frame through the multiple stirring components set up. The two first connecting rods set up will rotate with the connection point of the first connecting rod and the rotating seat as the center of the circle when they are driven upward by the second connecting rod. Moreover, the connection between the two first connecting rods and the motor fixing seat can make the spiral stirring rod on the charging wireless motor always move parallel to the inner wall of the reactor. This makes it possible to have a larger contact area with the silicone oil in the reactor while the spiral stirring rod rotates and swings up and down, so that the silicone oil in the reactor can be evenly mixed. The connection design of the two first connecting rods and the rotating seat makes it possible for the spiral stirring rod on the charging wireless motor to always move parallel to the inner wall of the reactor. This design maximizes the contact area between the spiral stirring rod and the silicone oil and promotes more sufficient mixing. The movement trajectory of the spiral stirring rod parallel to the inner wall ensures that the silicone oil in each area of ​​the reactor can be evenly stirred, reducing the risk of uneven mixing.

[0022] 3. The silicone oil preparation device, through the drive of the large sprocket arranged in the uniform mixing motion component, can make multiple stirring components rotate while swinging up and down evenly under the cooperation of the pulley and the corrugated fixed cylinder. The cooperation of the pulley driven by the large sprocket and the corrugated fixed cylinder realizes the compound motion of rotation and up and down swing of the stirring components. This motion mode ensures the all-round and dead-angle mixing of the silicone oil in the reactor. This compound motion mode not only increases the mixing path of the silicone oil raw material, but also breaks the stratification phenomenon in the mixing process through continuous ups and downs motion, thereby further improving the mixing effect.

[0035] Furthermore, the two rotating seats 8 in the stirring assembly are respectively fixedly connected to the outer surfaces of the two hexagonal sleeves 7, the two first connecting rods 9 are respectively rotatably connected in the corresponding rotating seats 8, and the two ends of the motor fixed seat 10 are respectively rotatably connected to the ends of the two first connecting rods 9 away from the rotating seat 8.

[0036] Furthermore, a charging radio motor 11 is fixedly connected to the outer surface of the motor fixing base 10 , and a spiral stirring rod 12 is fixedly sleeved on the outer surface of the output shaft of the charging radio motor 11 .

The second connecting rod 13 is used to drive the first connecting rod 9 to swing up and down.

[0038] Furthermore, the uniform mixing motion assembly further comprises a rotating cylinder 5 , which is fixedly connected to the upper end of the hexagonal shaft 6 , and a plurality of first slider grooves 14 are provided on the outer surface of the rotating cylinder 5 .

[0039] Furthermore, a plurality of waist-shaped slide grooves 15 are provided on the inner surface of the rotating cylinder 5 and communicate with the corresponding first slide grooves 14 , and the convex slide blocks 16 in the stirring assembly are slidably connected in the corresponding first slide grooves 14 .

[0040] Furthermore, the pulley 17 extends out of the waist-shaped slide groove 15, and the corrugated fixed cylinder 18 is rotatably connected to the bottom wall position in the rotating cylinder 5, and the upper surface of the corrugated fixed cylinder 18 is adapted to the pulley 17 in the stirring assembly.

[0041] Furthermore, the outer surface of the rotating cylinder 5 is rotatably connected to the moving plate 4, a large sprocket 20 is fixedly sleeved on the upper end of the rotating cylinder 5, a sprocket motor 21 is fixedly installed on the moving plate 4, and a motor sprocket 22 is fixedly sleeved on the outer surface of the output shaft of the sprocket motor 21.

[0042] Furthermore, a chain 23 is transmission-connected between the motor sprocket 22 and the large sprocket 20 , a connecting column fixing frame 24 is fixedly connected to the upper surface of the movable plate 4 , and a connecting column 19 for fixing the corrugated fixing cylinder 18 is fixedly connected between the connecting column fixing frame 24 and the corrugated fixing cylinder 18 .

[0043] Furthermore, a moving component 3 for driving the moving plate 4 to move up and down is provided on the support frame 1, and the moving plate 4 is fixedly connected to the moving end of the moving component 3. The outer surface of the reactor 2 is fixedly connected to a reactor heating component 25, and the reactor heating component 25 is fixedly connected to the support frame 1.

[0044] Furthermore, when in use, by starting the charging radio motor 11 in the multiple stirring components, the charging radio motor 11 will drive the spiral stirring rod 12 thereon to rotate, and at this time, the sprocket motor 21 is started. The sprocket motor 21 can drive the rotating drum 5 to rotate through the motor sprocket 22, the chain 23 and the large sprocket 20 arranged thereon. When the rotating drum 5 rotates, it can drive the hexagonal shaft 6 and the multiple stirring components thereon to rotate together. While the multiple stirring components are rotating, the corrugated fixed cylinder 18 is restricted and fixed by the connecting column 19 and the connecting column fixing frame 24, so that the corrugated fixed cylinder 18 does not rotate. When the multiple stirring components rotate together, the pulley 17 therein will be driven by the upper surface of the corrugated fixed cylinder 18, so that the pulley 17 can drive the corrugated fixed cylinder 18 and the second connecting rod 13 thereon to move upward along the axial direction of the first slider groove 14. At the same time, because the pulleys 17 on the multiple stirring components are downwardly fitted under the action of their own gravity, the multiple stirring components The pulley 17 on the mixing component will be at different heights, rotating and undulating at the same time, so that the second connecting rod 13 on multiple stirring components can follow and drive the first connecting rod 9 to move upward. The upward movement of the first connecting rod 9 can drive the charging radio motor 11 to swing up and down through the motor fixing seat 10, which can make the spiral stirring rod 12 rotating on the charging radio motor 11 swing up and down on the basis of the revolution of the hexagonal shaft 6. The spiral stirring rod 12 is driven to rotate by the charging radio motor 11, and combined with the up and down swinging of the stirring component on the corrugated fixing cylinder 18, the all-round and three-dimensional mixing of the silicone oil raw material in the reactor 2 is realized, avoiding the mixing dead corners in the traditional stirring method, especially the top and bottom areas of the reactor 2, and the edge areas, which are prone to uneven mixing of the silicone oil raw materials. This movement mode not only covers the upper and lower spaces and the radius space, but also takes into account the mixing of the inner circle and the outer circle, ensuring the uniform mixing of the silicone oil raw materials.

[0045] Furthermore, the multiple stirring assemblies are capable of swinging up and down in the support frame 1, and the two first connecting rods 9 are driven upward by the second connecting rod 13, so that they rotate with the connection point between the first connecting rod 9 and the rotating seat 8 as the center of the circle, and the connection between the two first connecting rods 9 and the motor fixing seat 10 enables the spiral stirring rod 12 on the charging radio motor 11 to always move parallel to the inner wall of the reactor 2, so that when the spiral stirring rod 12 rotates and swings up and down, it can have a larger contact area with the silicone oil in the reactor 2, so that the silicone oil in the reactor 2 can be evenly mixed. The connection design of the two first connecting rods 9 and the rotating seat 8 enables the spiral stirring rod 12 on the charging radio motor 11 to always move parallel to the inner wall of the reactor 2. This design maximizes the contact area between the spiral stirring rod 12 and the silicone oil, promotes more sufficient mixing, and the movement trajectory of the spiral stirring rod 12 parallel to the inner wall ensures that the silicone oil in each area of ​​the reactor 2 can be evenly stirred, reducing the risk of uneven mixing.

[0046] Furthermore, by driving the large sprocket 20 arranged in the uniform mixing motion component, the cooperation of the pulley 17 and the corrugated fixed cylinder 18 can enable multiple stirring components to rotate while swinging up and down evenly. The cooperation of the pulley 17 driven by the large sprocket 20 and the corrugated fixed cylinder 18 realizes the composite motion of rotation and up and down swinging of the stirring component. This motion mode ensures the all-round and dead-angle mixing of the silicone oil in the reactor 2. This composite motion mode not only increases the mixing path of the silicone oil raw material, but also breaks the stratification phenomenon in the mixing process through continuous ups and downs motion, thereby further improving the mixing effect.

[0047] Working principle: When in use, by starting the charging radio motor 11 in the multiple stirring components, the charging radio motor 11 will drive the spiral stirring rod 12 thereon to rotate, and then start the sprocket motor 21. The sprocket motor 21 can drive the rotating drum 5 to rotate through the motor sprocket 22, the chain 23 and the large sprocket 20 provided thereon. When the rotating drum 5 rotates, it can drive the hexagonal shaft 6 and the multiple stirring components thereon to rotate together. While the multiple stirring components are rotating, the corrugated fixed cylinder 18 is restricted and fixed by the connecting column 19 and the connecting column fixing frame 24, so that the corrugated fixed cylinder 18 will not rotate. When the multiple stirring components rotate together, the pulley 17 therein will be driven by the upper surface of the corrugated fixed cylinder 18, so that the pulley 17 can drive the corrugated fixed cylinder 18 and the second connecting rod 13 thereon along the first slider groove 14. The axis direction moves upward, and at the same time, since the pulleys 17 on the multiple stirring components are pressed downward under the action of the self-gravity of the charging radio motor 11, the pulleys 17 on the multiple stirring components will be at different height positions, rotating and undulating, so that the second connecting rod 13 on the multiple stirring components can follow and drive the first connecting rod 9 to move upward, and the upward movement of the first connecting rod 9 can drive the charging radio motor 11 to swing up and down through the motor fixing seat 10, which can make the spiral stirring rod 12 rotating on the charging radio motor 11 swing up and down on the basis of the revolution of the hexagonal shaft 6. The spiral stirring rod 12 is driven to rotate by the charging radio motor 11, and combined with the up and down swinging of the stirring component on the corrugated fixing cylinder 18, all-round and three-dimensional mixing of the silicone oil raw material in the reactor 2 is achieved.
