Polyurethane high-speed dispersion kettle

Abstract

This utility model belongs to the field of polyurethane processing, specifically a high-speed polyurethane dispersion kettle, including a dispersion kettle body with a connecting valve on the inner side. By setting up a first motor, pulleys, a belt, and a first stirring rod, and through the slotting of the cylindrical groove on the inner side of the dispersion kettle body and the horizontal placement of the first stirring rod, the first motor drives one pulley to rotate, which in turn drives the belt to rotate, which in turn drives the other pulley to rotate, causing a rotating plate to rotate. This rotating plate then causes the stirring blades of the first stirring rod to rotate up and down, ensuring that the distance between the stirring blades of the first stirring rod and the upper and lower sides of the cylindrical groove on the inner side of the dispersion kettle body is equal. This results in more frequent contact between the first stirring rod and the lower polyurethane, and the first stirring rod causes the lower polyurethane to rise and mix with the upper polyurethane, making the mixing more uniform and improving the mixing stability of the device.

Description

Technical Field

[0001] This utility model relates to the field of polyurethane processing, specifically a high-speed polyurethane dispersion autoclave. Background Technology

[0002] Polyurethane is a polymer compound produced by the addition polymerization reaction of isocyanate and polyol. Due to its excellent physical properties and chemical stability, polyurethane materials are widely used in many fields such as coatings, elastomers, foams, adhesives, and fibers. In the production process of polyurethane, a dispersion tank is required to stir it so that the reaction is more uniform.

[0003] However, the existing dispersion tanks have relatively fixed stirring structures, which makes it difficult for the polyurethane on the bottom side of the tank to come into contact with the stirring structure, resulting in uneven stirring. Therefore, a high-speed polyurethane dispersion tank is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-speed polyurethane dispersion vessel of this utility model includes a dispersion vessel body, a connecting valve connected to the inner side of the dispersion vessel body, a rotating plate rotatably connected to the inner side of the dispersion vessel body, a first motor fixedly connected to the outer side of the dispersion vessel body, pulleys fixedly connected to the outer side of one side of the rotating plate and the output end of the first motor, a belt rotatably connected to the outer side of the pulleys, and a first stirring rod fixedly connected to the inner side of the rotating plate; this step, by setting the first motor, pulleys, belt, and first stirring rod, and through the opening of the cylindrical groove on the inner side of the dispersion vessel body... The horizontal placement of the tank and the first stirring rod allows the first motor to drive one side pulley to rotate, which in turn drives the belt to rotate, which in turn drives the other side pulley to rotate, causing the rotating plate to rotate. This rotating plate then causes the stirring blades of the first stirring rod to rotate up and down, ensuring that the distance between the stirring blades of the first stirring rod and the upper and lower sides of the cylindrical tank inside the dispersion vessel is equal. This results in more frequent contact between the first stirring rod and the polyurethane on the lower side, and the first stirring rod also causes the polyurethane on the lower side to rise and mix with the polyurethane on the upper side, resulting in more uniform mixing and improved mixing stability of the device.

[0006] Preferably, a second motor is fixedly connected to the outside of the dispersion vessel body, a first gear is fixedly connected to the output end of the second motor, a second gear meshes with the outside of the first gear, a rotating block is rotatably connected to the inside of the rotating plate, one side of the rotating block and the second gear are fixedly connected, and a loading box is fixedly connected to the side of the rotating blocks that are close to each other. In this step, by setting up the second motor, the first gear, the second gear, the rotating block and the loading box, when the rotating plate drives the first stirring rod to rotate up and down to stir the polyurethane, the second motor can drive the first gear to rotate, the first gear can drive the second gear to rotate, and the second gear can drive the rotating block to rotate, so that the rotating block drives the loading box to rotate to a suitable direction, so as to load part of the polyurethane at the bottom of the inner side of the dispersion vessel body into the inner side of the loading box. By raising the loading box, the polyurethane is also raised, which makes the contact between the upper and lower sides of the polyurethane more frequent, and further improves the stability of loading and mixing.

[0007] Preferably, a third gear meshes with the outer side of the first gear, and a second stirring rod is rotatably connected to one side of the third gear. Both the second stirring rod and the third gear are rotatably connected to the rotating plate. This step, by setting the third gear and the second stirring rod, will synchronously drive the second stirring rod and the third gear to move when the rotating plate rotates, so that the second stirring rod comes into contact with and collides with the polyurethane, thereby further breaking down the polyurethane. When the first gear drives the loading box to adjust its opening angle, it will synchronously drive the third gear to rotate, and the third gear will drive the second stirring rod to rotate, thereby cooperating with the first stirring rod to further stir and break down the polyurethane, further improving the uniformity of the device's breaking down.

[0008] Preferably, a limiting ring is fixedly connected to the outer side of one side of the rotating plate, and the first gear, the second gear, and the third gear are all used in conjunction with the limiting ring. This step, by setting the limiting ring, allows the rotating plate to fit tightly against the two side planes of the first gear, the second gear, and the third gear, making the meshing between them more efficient and improving the stability of the device operation.

[0009] Preferably, a groove is provided on the inner side of the first stirring rod, and a heating tube is rotatably connected to the inner side of the groove. The heating tube is fixedly connected to the dispersion vessel body. This step, by setting the groove and the heating tube, allows the first stirring rod to be heated through the heating tube when the polyurethane needs to be heated, thereby heating the polyurethane through the first stirring rod, which improves the practicality of the device.

[0010] Preferably, a mounting plate is fixedly connected to the outside of the dispersion vessel body, and a mounting groove is formed on the surface of the mounting plate; this step improves the convenience of device installation by setting up the mounting plate and the mounting groove, and by screwing bolts into the mounting groove and the mounting location.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a first motor, pulleys, belts, and a first stirring rod, and through the slotting of the cylindrical groove inside the dispersion vessel body and the horizontal placement of the first stirring rod, enables the first motor to drive one side pulley to rotate, which in turn drives the belt to rotate, which in turn drives the other side pulley to rotate, which in turn drives the rotating plate to rotate, which in turn drives the stirring blades of the first stirring rod to rotate up and down. This ensures that the stirring blades of the first stirring rod are equidistant from the upper and lower sides of the cylindrical groove inside the dispersion vessel body, thereby increasing the contact between the first stirring rod and the polyurethane on the lower side. The first stirring rod also causes the polyurethane on the lower side to rise and mix with the polyurethane on the upper side, resulting in more uniform mixing and improved mixing stability of the device.

[0013] 2. This utility model, by setting up a second motor, a first gear, a second gear, a rotating block, and a loading box, allows the first gear to rotate when the rotating plate drives the first stirring rod to stir the polyurethane. The second motor then drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear then drives the rotating block to rotate, causing the rotating block to rotate the loading box to a suitable direction. This allows some of the polyurethane at the bottom of the dispersion vessel to be loaded into the loading box. Furthermore, the lifting of the loading box causes the polyurethane to rise, resulting in more frequent contact and exchange of polyurethane between the upper and lower sides, thus further improving the stability of the loading and mixing process.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, a high-speed polyurethane dispersion vessel includes a dispersion vessel body 1. A connecting valve 2 is connected to the inner side of the dispersion vessel body 1. A rotating plate 3 is rotatably connected to the inner side of the dispersion vessel body 1. A first motor 4 is fixedly connected to the outer side of the dispersion vessel body 1. A pulley 5 is fixedly connected to the outer side of one side of the rotating plate 3 and the output end of the first motor 4. A belt 6 is rotatably connected to the outer side of the pulley 5. A first stirring rod 7 is fixedly connected to the inner side of the rotating plate 3. This step, through the arrangement of the first motor 4, pulley 5, belt 6, and first stirring rod 7, utilizes the slotting of the cylindrical groove inside the dispersion vessel body 1 and the lateral placement of the first stirring rod 7... The first motor 4 drives one side pulley 5 to rotate, which in turn drives the belt 6 to rotate, which in turn drives the other side pulley 5 to rotate. This causes the other side pulley 5 to rotate the rotating plate 3, which in turn causes the stirring blades of the first stirring rod 7 to rotate up and down. This ensures that the stirring blades of the first stirring rod 7 are equidistant from the upper and lower sides of the cylindrical groove inside the dispersion vessel body 1. Consequently, the first stirring rod 7 comes into more frequent contact with the polyurethane on the lower side, and the first stirring rod 7 causes the polyurethane on the lower side to rise and mix with the polyurethane on the upper side, resulting in a more uniform mixture and improved mixing stability of the device.

[0024] Furthermore, such as Figure 1 and Figure 3As shown, a second motor 8 is fixedly connected to the outside of the dispersion vessel body 1. A first gear 9 is fixedly connected to the output end of the second motor 8. A second gear 10 meshes with the outside of the first gear 9. A rotating block 11 is rotatably connected to the inside of the rotating plate 3. One side of the rotating block 11 and the second gear 10 are fixedly connected. A loading box 12 is fixedly connected to the side of the rotating blocks 11 that are close to each other. In this step, by setting up the second motor 8, the first gear 9, the second gear 10, the rotating block 11, and the loading box 12, when the rotating plate 3 drives the first stirring rod 7 to rotate up and down to stir the polyurethane, the second motor 8 can drive the first gear 9 to rotate, the first gear 9 can drive the second gear 10 to rotate, and the second gear 10 can drive the rotating block 11 to rotate. This causes the rotating block 11 to drive the loading box 12 to rotate to a suitable direction, so that part of the polyurethane at the bottom of the inner side of the dispersion vessel body 1 is loaded into the inner side of the loading box 12. By raising the loading box 12, the polyurethane is also raised, which makes the contact between the upper and lower sides of the polyurethane more frequent, further improving the stability of the loading and mixing.

[0025] Furthermore, such as Figure 3 As shown, a third gear 13 meshes with the outer side of the first gear 9. A second stirring rod 14 is rotatably connected to one side of the third gear 13. Both the second stirring rod 14 and the third gear 13 are rotatably connected to the rotating plate 3. In this step, by setting the third gear 13 and the second stirring rod 14, when the rotating plate 3 rotates, it will synchronously drive the second stirring rod 14 and the third gear 13 to move, so that the second stirring rod 14 comes into contact with the polyurethane, thereby further dispersing the polyurethane. When the first gear 9 drives the loading box 12 to adjust its opening angle, it will synchronously drive the third gear 13 to rotate. The third gear 13 drives the second stirring rod 14 to rotate, thereby cooperating with the first stirring rod 7 to further stir and disperse the polyurethane, further improving the uniformity of the device's dispersion.

[0026] Furthermore, such as Figure 1 As shown, a limiting ring 15 is fixedly connected to the outer side of the rotating plate 3 on one side. The first gear 9, the second gear 10, and the third gear 13 are all used in conjunction with the limiting ring 15. This step, by setting the limiting ring 15, allows the rotating plate 3 to fit tightly against the two side planes of the first gear 9, the second gear 10, and the third gear 13, making their meshing more efficient and improving the stability of the device operation.

[0027] Furthermore, such as Figure 2 and Figure 5As shown, a groove 16 is provided on the inner side of the first stirring rod 7, and a heating tube 17 is rotatably connected to the inner side of the groove 16. The heating tube 17 is fixedly connected to the dispersion vessel body 1. This step, by setting the groove 16 and the heating tube 17, allows the first stirring rod 7 to be heated through the heating tube 17 when the polyurethane needs to be heated, thereby heating the polyurethane through the first stirring rod 7, which improves the practicality of the device.

[0028] Furthermore, such as Figure 2 As shown, an installation plate 18 is fixedly connected to the outside of the dispersion vessel body 1, and an installation groove 19 is provided on the surface of the installation plate 18. This step improves the convenience of device installation by setting the installation plate 18 and the installation groove 19 and screwing the bolts into the installation groove 19 and the installation location to install and fix the device.

[0029] The working principle is as follows: Polyurethane is poured into the inner side of the dispersion vessel body 1. The first motor 4 drives one side pulley 5 to rotate, which in turn drives the belt 6 to rotate. The belt 6 drives the other side pulley 5 to rotate, which in turn drives the rotating plate 3 to rotate. The rotating plate 3 drives the stirring blades of the first stirring rod 7 to rotate up and down, which in turn drives the second stirring rod 14 to move up and down, thus cooperating with the first stirring rod 7 to uniformly stir the polyurethane. At the same time, the second motor 8 is started, which drives the first gear 9 to rotate, which in turn drives the second gear 10 to rotate, which in turn drives the rotating block 11 to rotate. The rotating block 11 drives the loading box 12 to rotate to a suitable direction, so that part of the polyurethane at the bottom of the inner side of the dispersion vessel body 1 is loaded into the loading box 12. The loading box 12 is then raised, causing the polyurethane to rise. Then, the loading box 12 is rotated to pour the polyurethane down, making its position change more frequent and achieving more uniform mixing.
