Description

Technical Field

[0001] The present application relates to the field of latex production equipment, and in particular to a polymerization device for safe production of latex. Background Art

[0002] Styrene-butadiene latex is produced through the emulsion copolymerization of butadiene and styrene. Different grades are available depending on the ratio of styrene to butadiene. Depending on the temperature of the emulsion copolymerization, there are high-temperature (50°C) and low-temperature (5°C) styrene-butadiene latex. The latter outperforms the former, offering higher strength and better cold resistance. Styrene-butadiene latex adhesives are more heat-resistant and aging-resistant than natural rubber latex adhesives. Even after aging, they do not become sticky or soften, but rather harden.

[0003] During the production of styrene-butadiene latex, ingredients need to be mixed and added to the processing barrel. During the addition, intermittent addition is usually done manually, which is cumbersome to operate. There are also feeding channels for feeding, but the materials include liquid materials and granular or powdered materials. The two materials are usually added in sequence through the same feeding channel. This causes part of the later added material to react with the remaining earlier added material in the channel and adhere to the channel, resulting in channel blockage and reduced feeding efficiency. Summary of the Invention

[0004] In order to improve the feeding efficiency of a polymerization device, the present application provides a polymerization device for safe production of latex.

[0005] The present application provides a polymerization device for safe production of latex using the following technical solutions:

[0006] A polymerization device for the safe production of latex includes a polymerization tank body, a polymerization top cover is installed on the top of the polymerization tank body, a rotating shaft is inserted into the interior of the polymerization tank body, and at least two feeding components are provided on the polymerization top cover. At least two feeding components are respectively arranged on the polymerization top cover, and each feeding component allows materials of the same form to pass through.

[0007] By adopting the above technical solution, independent feeding channel designs for materials in different forms are realized, avoiding the problem of channel blockage caused by mixing reaction between liquid materials and granular or powdered materials during the feeding process, thereby significantly improving the feeding efficiency of the polymerization device.

[0008] Preferably, the feeding assembly includes a feeding pipe, a feeding hole is opened on the polymerization top cover, one end of the feeding pipe is inserted into the feeding hole, and the feeding pipe is connected with the inner cavity of the polymerization tank through the feeding hole.

[0009] By adopting this technical solution, the feed pipe allows different materials to enter the polymerization tank through their own channels, avoiding blockage caused by the mixing of liquid materials and granular or powdered materials in the same feeding channel. The design of the feed hole and the connection between the feed pipe and the interior of the polymerization tank ensure smooth material transportation, thereby improving the feeding efficiency of the polymerization device.

[0010] Preferably, an auxiliary uniformization component is provided in the polymerization tank body, and the auxiliary uniformization component includes a special-shaped ring, and the circumferential distance of the special-shaped ring to the rotating shaft continuously changes; the special-shaped ring is connected to the rotating shaft and rotates synchronously with the rotating shaft, and a matching component is provided between the feeding tube and the special-shaped ring, and the feeding tube is continuously connected to the special-shaped ring by using the matching component during the period of synchronous rotation of the special-shaped ring with the rotating shaft; multiple feeding tubes are installed at different positions on the special-shaped ring through the matching component.

[0011] By adopting the above technical solution, the circumferential distance from the special-shaped ring to the rotating shaft continuously changes, and multiple feeding pipes are installed at different positions of the special-shaped ring through matching components, so that materials of different forms can be added at different positions and quickly dispersed, avoiding premature reaction and blockage problems between materials, and further improving feeding efficiency and production safety.

[0012] Preferably, the mating component includes a connecting ring, a sliding ring and a connecting tube, the feeding hole is a waist-shaped hole, the sliding ring is slidably set in the feeding hole, the sliding ring is slidably connected to the polymerization top cover, and the feeding tube is fixedly installed on the sliding ring at one end close to the feeding hole; a movable ring groove is provided on the peripheral wall of the special-shaped ring, the connecting ring is slidably connected to the special-shaped ring and can move along the movable ring groove, one end of the connecting tube is connected to the connecting ring and the other end is connected to the sliding ring, the connecting ring moves in the movable ring groove when the special-shaped ring rotates, and the material in the feeding tube is discharged into the polymerization tank body through the connecting tube.

[0013] By adopting this technical solution, the rotation of the shaped ring drives the connecting ring to move within the movable ring groove, which in turn drives the sliding ring to slide within the waist-shaped hole through the connecting tube. This design allows the position of the feeding tube to change with the rotation of the shaped ring, thereby achieving uniform material distribution. This ensures smooth material transfer and further improves feeding efficiency.

[0014] Preferably, a protective sleeve is further provided on the feeding tube, a protective slide is provided on the polymer top cover, the protective sleeve is slidably connected to the protective slide, and when the sliding ring moves in the feeding hole, the protective sleeve slides synchronously on the protective slide.

[0015] By adopting the above technical solution, the provision of a protective sleeve and a protective carriage effectively reduces wear on the feeding tube during movement, thereby increasing its service life. Furthermore, the sliding coordination between the protective sleeve and the protective carriage ensures the stability of the feeding tube as it moves with the sliding ring, preventing deviation or jamming caused by external interference, thereby improving the reliability of the entire polymerization device during the feeding process.

[0016] Preferably, there are multiple special-shaped rings, the special-shaped ring close to the polymer top cover is connected to the feeding tube through a matching component, and the remaining special-shaped rings are installed on the rotating shaft in sequence along the axial direction of the rotating shaft; the auxiliary uniform component also includes a mixing plate, multiple connecting rods and multiple sealing reset parts, the connecting rods are installed on the inner wall of the polymer tank, and the mixing plate is installed on the connecting rods through the sealing reset part; the mixing plate can interfere with the outer peripheral wall of the special-shaped ring and can be close to or away from the rotating shaft.

[0017] By adopting the above technical solution, the provision of multiple special-shaped rings enables the material to be guided and dispersed at different heights and positions, thereby achieving a more uniform mixing effect. The special-shaped ring near the polymerization top cover is connected to the feeding pipe through a matching component, ensuring that the material can be immediately guided to the appropriate position after being discharged from the feeding pipe, avoiding material accumulation or uneven distribution. The remaining special-shaped rings are installed in sequence along the axis of the rotating shaft, further enhancing the fluidity and mixing uniformity of the material in the polymerization tank. The mixing plate in the auxiliary uniform component is installed on the connecting rod through a sealing reset member, which can contact the outer peripheral wall of the special-shaped ring when the special-shaped ring rotates, and at the same time, under the action of the sealing reset member and the special-shaped ring, it approaches or moves away from the rotating shaft, thereby dynamically adjusting and mixing the material, effectively improving the mixing efficiency and uniformity. This design not only improves the feeding efficiency, but also significantly improves the overall performance of the polymerization device.

[0018] Preferably, the sealing reset part includes a stabilizing ring, two reset springs and a sealing telescopic tube, the stabilizing ring is adapted to slide on the connecting rod, the two reset springs are both sleeved on the connecting rod and are respectively arranged on both sides of the stabilizing ring, one end of the reset spring is connected to the side wall of the stabilizing ring, and the other end is connected to the end of the connecting rod; the sealing telescopic tube is sleeved on the two reset springs, one end of the sealing telescopic tube is sealed and connected to the inner wall of the polymerization tank, and the other end is connected to the end of the connecting rod; the outer peripheral wall of the stabilizing ring is fixedly connected to the inner wall of the sealing telescopic tube, the end wall of the mixing plate is fixedly connected to the outer wall of the sealing telescopic tube, and the mixing plate and the stabilizing ring are symmetrically arranged on the outer and inner sides of the sealing telescopic tube.

[0019] By adopting the above-mentioned technical solution, the provision of the sealing reset member can achieve a stable reset and sealing effect for the mixing plate. Specifically, the sliding movement of the stabilizing ring on the connecting rod, combined with the elastic action of the two reset springs, ensures that the mixing plate can automatically reset after contact with the special-shaped ring, thus avoiding irreversible displacement of the mixing plate due to external forces. At the same time, the provision of the sealing telescopic tube effectively prevents material leakage, and its sealed connection with the inner wall of the polymerization tank and the end of the connecting rod further enhances the sealing performance of the overall device. In addition, the design of symmetrically arranging the mixing plate and the stabilizing ring on the inner and outer sides of the sealing telescopic tube makes the structure more compact and reasonable, enhances the movement stability of the mixing plate, and thus improves the uniformity of material mixing.

[0020] Preferably, a contact guide arc plate is provided on one side of the mixing plate close to the special-shaped ring, and there is always a gap between the two ends of the contact guide arc plate and the special-shaped ring.

[0021] By adopting the above technical solution, a contact guide arc plate is provided on the side of the mixing plate close to the special-shaped ring, and there is always a gap between the two ends of the contact guide arc plate and the special-shaped ring, which can effectively avoid the wear caused by direct contact between the mixing plate and the special-shaped ring, and at the same time ensure that during the rotation of the special-shaped ring, the material is more evenly distributed under the guidance of the contact guide arc plate, thereby improving the mixing effect and reducing equipment loss.

[0022] Preferably, the special-shaped ring is elliptical, the minimum distance from the special-shaped ring to the rotation axis is the distance from the short axis focus of the special-shaped ring to the rotation axis, and the maximum distance from the special-shaped ring island rotation axis is the distance from the long axis focus of the special-shaped ring to the rotation axis.

[0023] By employing this technical solution, the elliptical profiled ring can periodically change its relative distance from the rotating shaft during rotation. This design allows the feed tube mounted on the profiled ring to achieve periodic positional changes through mating components, resulting in a more uniform distribution of materials as they enter the polymerization tank. Specifically, in this solution, the minor and major axis focal points of the profiled ring determine its minimum and maximum distances from the rotating shaft, respectively. This feature further optimizes the feed tube's positional range, improves the uniformity of material mixing, and thus enhances the overall feeding efficiency of the polymerization unit.

[0024] Preferably, the diameters of the plurality of feeding tubes are inconsistent.

[0025] By adopting this technical solution, multiple feeding pipes with different diameters can be used to transport materials with different shapes and flow requirements. This design improves the accuracy of material transfer, reduces material residue and mixing during the feeding process, thus preventing channel blockage and further improving the feeding efficiency of the polymerization device.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The independent feeding channel design for materials in different forms avoids the problem of channel blockage caused by mixing reaction between liquid materials and granular or powdered materials during the feeding process, thereby significantly improving the feeding efficiency of the polymerization device;

[0028] The distance from the circumference of the special-shaped ring to the rotating shaft continuously changes. Multiple feeding pipes are installed at different positions of the special-shaped ring through matching components, so that materials of different forms can be added at different positions and quickly dispersed, avoiding premature reaction and blockage between materials, further improving feeding efficiency and production safety.

[0029] The mixing plate in the auxiliary homogenization assembly is mounted on the connecting rod via a sealing reset member. This plate contacts the outer wall of the shaped ring as it rotates. The sealing reset member and the shaped ring simultaneously move the plate closer to or further from the rotating shaft, dynamically adjusting and mixing the material, effectively improving mixing efficiency and uniformity. This design not only increases feeding efficiency but also significantly enhances the overall performance of the polymerization unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The present application discloses a polymerization device for the safe production of latex. Figure 1and Figure 2 The polymerization device for safe production of latex includes a polymerization tank body 1, which is placed on the ground. A polymerization top cover 2 is installed on the top of the polymerization tank body 1. The polymerization top cover 2 is provided with a rotating shaft 3 inserted into the interior of the polymerization tank body 1. The rotating shaft 3 is rotatably connected to the polymerization top cover 2 through a bearing and is driven to rotate by a motor. A stirring blade is provided at one end of the rotating shaft 3 located in the polymerization tank body 1 to mix the materials in the polymerization tank body 1.

[0037] At least two feeding assemblies 4 are provided on the polymer cover 2. In this embodiment, three feeding assemblies 4 are provided, one on each polymer cover 2, each for passing materials of the same form. The feeding assemblies 4 include a feeding tube 41. A feeding hole 21 is provided on the polymer cover 2. One end of the feeding tube 41 is inserted into the feeding hole 21, and the feeding tube 41 communicates with the inner cavity of the polymer tank 1 through the feeding hole 21. The diameters of the multiple feeding tubes 41 are different. In this embodiment, the feeding tube 41 with the smallest diameter is used to transport liquid materials, the feeding tube 41 with the largest diameter is used to transport granular materials, and the feeding tube 41 with an intermediate diameter is used to transport powder materials.

[0038] The design of independent feeding channels for materials in different forms avoids the problem of channel blockage caused by mixing reaction between liquid materials and granular or powdered materials during the feeding process, thereby significantly improving the feeding efficiency of the polymerization device.

[0039] Reference Figure 2 and Figure 3 An auxiliary uniform component 5 is provided in the polymerization tank body 1, and the auxiliary uniform component 5 includes a special-shaped ring 51. In this embodiment, a plurality of special-shaped rings 51 are provided, and the plurality of special-shaped rings 51 are fixedly installed on the rotating shaft 3 in sequence along the axial direction of the rotating shaft 3; in this embodiment, the special-shaped ring 51 is elliptical, and the minimum distance from the special-shaped ring 51 to the rotating shaft 3 is the distance from the short-axis focus of the special-shaped ring 51 to the rotating shaft 3, and the maximum distance from the special-shaped ring 51 to the rotating shaft 3 is the distance from the long-axis focus of the special-shaped ring 51 to the rotating shaft 3.

[0040] The circumferential distance of the special-shaped ring 51 to the rotating shaft 3 continuously changes, and the special-shaped ring 51 is connected to the rotating shaft 3 and rotates synchronously with the rotating shaft 3; one of the special-shaped rings 51 is located at the top of the rotating shaft 3, and a matching component 6 is provided between the feeding tube 41 and the special-shaped ring 51 located at the top of the rotating shaft 3. During the period when the special-shaped ring 51 rotates synchronously with the rotating shaft 3, the feeding tube 41 is continuously connected to the special-shaped ring 51 by means of the matching component 6; multiple feeding tubes 41 are installed at different positions on the special-shaped ring 51 through the matching component 6.

[0041] The feeding hole 21 is a waist-shaped hole, and a soft sealing material is provided at the feeding hole 21 to cover the waist-shaped hole. A notch is provided in the soft sealing material to allow the feeding tube 41 to move. The feeding tube 41 can prop the notch open, and the notch is closed where the feeding tube 41 is not present. Because the feeding tube 41 is limited by the inner wall of the feeding hole 21 but is movably connected to the special-shaped ring 51 through the mating component 6, the feeding tube 41 reciprocates along the length of the feeding hole 21 as the special-shaped ring 51 rotates synchronously with the rotating shaft 3. This allows materials of different forms to be added at different locations and quickly dispersed, avoiding premature reactions and blockages between materials, further improving feeding efficiency and production safety.

[0042] The mating component 6 includes a sliding ring 62, which is slidably arranged in the feeding hole 21. The sliding ring 62 is slidably connected to the polymer top cover 2, and the end of the feeding tube 41 close to the feeding hole 21 is fixedly installed on the sliding ring 62; during the movement of the sliding ring 62 in the feeding hole 21, the feeding tube 41 moves synchronously with the sliding ring 62, and the feeding tube 41 is also provided with a removable protective sleeve 42. A protective slide 42 is installed on the polymer top cover 2 by bolts, and the protective slide 43 is slidably connected to the protective slide 43. When the sliding ring 62 moves in the feeding hole 21, the protective sleeve 42 slides synchronously on the protective slide 43.

[0043] A movable ring groove 52 is provided on the peripheral wall of the special-shaped ring 51. The special-shaped ring 51 is located in the movable ring groove 52 and is slidably connected to a connecting ring 61. The connecting ring 61 is movably connected to the special-shaped ring 51 through a rotating ball, and the connecting ring 61 can slide along the circumference of the movable ring groove 52. A connecting pipe 63 is installed on the connecting ring 61 and the sliding ring 62. The end of the connecting pipe 63 close to the sliding ring 62 is fixedly connected to the feeding pipe 41, so that the connecting pipe 63 is connected to the feeding pipe 41. The end of the connecting pipe 63 close to the connecting ring 61 is rotatably connected to the connecting ring 61. The connecting ring 61 moves in the movable ring groove 52 when the special-shaped ring 51 rotates, and the material in the feeding pipe 41 is discharged into the polymerization tank body 1 through the connecting pipe 63.

[0044] Reference Figure 2 and Figure 4 Except for the special-shaped ring 51 connected to the feeding tube 41, the other special-shaped rings 51 play an auxiliary role in stirring the material. The auxiliary uniform component 5 also includes a mixing plate 53, multiple connecting rods 54 and multiple sealing reset parts 55. The connecting rods 54 are installed on the inner wall of the polymerization tank body 1 through bolts, and the mixing plate 53 is installed on the connecting rods 54 through the sealing reset parts 55; the mixing plate 53 can interfere with the outer peripheral wall of the special-shaped ring 51 that stirs the material, and can approach or move away from the rotating shaft 3.

[0045] The sealing return member 55 includes a stabilizing ring 551, two return springs 552 and a sealing telescopic tube 553. The stabilizing ring 551 is adapted to slide on the connecting rod 54. The two return springs 552 are both mounted on the connecting rod 54 and are respectively arranged on both sides of the stabilizing ring 551. One end of the return spring 552 is connected to the side wall of the stabilizing ring 551, and the other end is connected to the end of the connecting rod 54.

[0046] The sealing telescopic tube 553 is sleeved on two return springs 552, one end of the sealing telescopic tube 553 is sealed and connected to the inner wall of the polymerization tank body 1, and the other end is connected to the end of the connecting rod 54; the outer peripheral wall of the stabilizing ring 551 is fixedly connected to the inner wall of the sealing telescopic tube 553; the end wall of the mixing plate 53 is fixedly connected to the outer wall of the sealing telescopic tube 553, and the mixing plate 53 and the stabilizing ring 551 are symmetrically arranged on the outer and inner sides of the sealing telescopic tube 553. In this embodiment, in order to improve the stability of the mixing plate 53 during installation, a connecting short rod is provided between the mixing plate 53 and the stabilizing ring 551, and the mixing plate 53 and the stabilizing ring 551 clamp the sealing telescopic tube 553 to achieve sealing.

[0047] A contact guide arc plate 531 is provided on the side of the mixing plate 53 near the shaped ring 51. A gap always exists between the ends of the contact guide arc plate 531 and the shaped ring 51. During the rotation of the shaped ring 51, the long axis of the shaped ring 51 contacts the contact guide arc plate 531, which smoothly guides the long axis of the shaped ring 51 to the mixing plate 53. At this time, the mixing plate 53, under the action of the shaped ring 51, moves away from the rotating shaft 3 to stir the material. When the long axis of the shaped ring 51 rotates out of the contact guide arc plate 531, the mixing plate 53, under the action of the return spring 552, moves back toward the rotating shaft 3 to stir the material again.

[0048] The implementation principle of a polymerization device for safe production of latex in an embodiment of the present application is as follows: during the rotation of the rotating shaft 3, the special-shaped ring 51 moves synchronously with the rotating shaft 3. Under the rotation of the special-shaped ring 51, the feeding tube 41 is limited by the inner wall of the feeding hole 21, so the connecting ring 61 slides along the movable ring groove 52, but because the inner diameter of the special-shaped ring 51 continues to change, the sliding ring 62 moves with the feeding tube 41 in the feeding hole 21, and the connecting tube 63 also moves back and forth, so that materials of different forms can be added at different positions and quickly dispersed, avoiding premature reaction and blockage problems between materials, and further improving feeding efficiency and production safety.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
