[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 As shown, an environmentally friendly polyether silane catalytic synthesis reactor includes: a reactor 1, and a catalytic mechanism 8 disposed within the reactor 1;

[0029] like Figures 2-3 As shown, a mounting plate 5 is fixedly connected to one side of the outer wall of the reactor 1. The bottom of the reactor 1 is hemispherical. The catalytic mechanism 8 includes: a motor 801, which is fixedly connected to one side of the mounting plate 5. One end of the output shaft of the motor 801 passes through the reactor 1 and is fixedly connected to a rotating rod 806. A connecting plate 802 is slidably connected to the outer circumference of the rotating rod 806. One side of the connecting plate 802 is rotatably connected to one side of the inner wall of the reactor 1.

[0030] A number of stirring plates 803 are slidably connected to the outer circumference of the connecting plate 802. A mixing plate 804 is fixedly connected to the inner circumference of each of the stirring plates 803. Two through slots 805 are opened on one side of each mixing plate 804. The outer circumference of each stirring plate 803 is tightly fitted to the inner circumference of the reactor 1.

[0031] It should be noted that the lower half of the reactor 1 is hemispherical, which helps to distribute materials evenly and reduce mixing dead zones. The catalytic mechanism 8 is driven by a motor 801 and is securely connected to one side of the reactor 1 via a mounting plate 5. The output shaft of the motor 801 drives the rotating rod 806 to rotate, which in turn drives the stirring plate 803 and the mixing plate 804 to stir within the reactor 1 via a connecting plate 802. The two through slots 805 on the mixing plate 804 enhance the material cutting and mixing effect, increasing the catalytic reaction rate. At the same time, the close fit between the stirring plate 803 and the inner wall of the reactor 1 ensures that material does not accumulate at the bottom of the reactor 1 during the reaction and can scrape the inner wall of the bottom of the reactor 1, effectively reducing material residue. When the mixing plate 804 moves, the material can flow out through the through slots 805, improving the reaction effect.

[0032] like Figures 2-3As shown, one end of the rotating rod 806 is provided with a reverse transmission assembly, which includes: a fixed plate 807, which is fixedly connected to the inner wall of the other side of the reactor 1, and a first gear 809 is fixedly connected to one end of the rotating rod 806.

[0033] The first gear 809 is rotatably connected to one side of the fixed plate 807. A plurality of second gears 810 are rotatably connected to one side of the fixed plate 807. A rotating cylinder 812 is rotatably connected to one side of the fixed plate 807. A plurality of tooth blocks 811 are fixedly connected to the inner circumference of the rotating cylinder 812. The outer circumference of the plurality of second gears 810 meshes with the outer circumference of the first gear 809. The plurality of second gears 810 are sleeved on the outer side of the plurality of second gears 810 and mesh. One side of the rotating cylinder 812 is rotatably connected to one side of the connecting plate 802. A plurality of reversing plates 813 are fixedly connected to the outer circumference of the rotating cylinder 812.

[0034] A protective shell 6 is fixedly connected to one side of the mounting plate 5. The motor 801 is located inside the protective shell 6. Several through heat dissipation grooves 4 are opened on the outer circumference of the protective shell 6. A transmission ring 808 is fixedly connected to the other end of several stirring plates 803. The inner circumference of the transmission ring 808 is rotatably connected to the outer circumference of the fixed plate 807. The top pipe of the reactor 1 is connected to the feed hopper 7. The bottom of the reactor 1 is fixedly connected to the discharge pipe 3. A valve is installed in the discharge pipe 3. Several support rods 2 are fixedly connected to the bottom of the reactor 1.

[0035] It should be noted that the rotation of the rotating rod 806 driven by the motor 801 not only causes the stirring plate 803 to freely stir within the reactor 1, but also, through the use of the reverse transmission assembly including: a fixed plate 807, a first gear 809, several second gears 810, a rotating cylinder 812 and its gear blocks 811, and a reverse plate 813, achieves dual reverse rotation of the stirring plate 803 and the reverse plate 813, improving the uniformity of material mixing and the efficiency of the catalytic reaction. The motor 801 is housed within the protective shell 6, and the heat dissipation groove 4 effectively dissipates heat, ensuring the long-term stable operation of the motor 801. The stirring plate 803, through the rotational connection between the transmission ring 808 and the fixed plate 807, and the synergistic effect of the reverse plate 813, achieves all-round, multi-angle stirring of the material. Furthermore, the feed hopper 7 at the top of the reactor 1 and the discharge pipe 3 connected to the bottom make the addition and discharge of materials simple and quick, improving production efficiency.

[0036] In use, this invention introduces materials into the reactor 1 through the feed hopper 7 for catalytic reaction. The motor 801 is started, causing its output shaft to rotate. This rotation drives the rotating rod 806, which in turn rotates the connecting plate 802 and several stirring plates 803 on its outer circumference within the reactor 1. The stirring plates 803 also cause several mixing plates 804 to move. During this movement, the grooves 805 on the mixing plates 804 facilitate material cutting and mixing. Simultaneously, the rotating rod 806 drives the first gear 809, which in turn drives several second gears 810. These second gears 810 then rotate the rotating cylinder 812 and its outer circumference's reversing plate 813. This rotation of the stirring plates 803 and mixing plates 804, along with the reversing plate 813, ensures comprehensive and multi-angle mixing and stirring of the materials within the reactor 1, guaranteeing sufficient contact between the catalyst and the raw materials for reaction. When the catalytic reaction is complete, open the valve on the discharge pipe 3 at the bottom of the reactor 1 to discharge the reaction product into the collection container.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
