Description

Technical Field

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

[0002] Styrene-butadiene latex in latex is made by emulsion copolymerization of butadiene and styrene. There are different grades according to the ratio of styrene to butadiene. According to the temperature of emulsion copolymerization, there are also high-temperature (50 °C) styrene-butadiene latex and low-temperature (5 °C) styrene-butadiene latex. The latter has better performance than the former, with higher strength and better cold resistance. The heat resistance and aging resistance of styrene-butadiene latex adhesives are both better than those of natural rubber latex adhesives. Even after aging, they do not become sticky or soften, but harden.

[0003] During the production of styrene-butadiene latex, batching is required and added to the processing barrel. During feeding, manual intermittent feeding is usually used, which is rather troublesome; there is also feeding using a feeding channel. However, there are liquid materials and granular or powdered materials in the materials. The two materials usually use the same feeding channel to feed one after another. This causes a 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 the polymerization device, the present application provides a polymerization device for the safe production of latex.

[0005] A polymerization device for the safe production of latex provided by the present application adopts the following technical solution: 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 inserted into the interior of the polymerization tank body is provided on the polymerization top cover. At least two feeding components are provided on the polymerization top cover. At least two of the feeding components are respectively arranged on the polymerization top cover, and each feeding component allows materials of the same form to pass through.

[0006] By adopting the above technical solution, an independent feeding channel design for materials of different forms is realized, avoiding the problem of channel blockage caused by the mixing reaction of liquid materials and granular or powdered materials during the feeding process, thereby significantly improving the feeding efficiency of the polymerization device.

[0007] Preferably, the feeding component 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 communicates with the inner cavity of the polymerization tank body through the feeding hole.

[0008] By adopting the above technical solution, the setting of the feeding pipe enables materials in different forms to enter the polymerization tank through their respective channels, avoiding the blockage problem caused by the mixing of liquid materials and granular or powdery materials in the same feeding channel. The opening of the feeding hole and the connection design between the feeding pipe and the inside of the polymerization tank ensure the smoothness of material transportation, thereby improving the feeding efficiency of the polymerization device.

[0009] Preferably, an auxiliary uniformity component is arranged in the polymerization tank. The auxiliary uniformity component includes a special-shaped ring, and the distance from the circumference 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. A matching component is arranged between the feeding pipe and the special-shaped ring. During the synchronous rotation of the special-shaped ring with the rotating shaft, the feeding pipe continuously connects with the special-shaped ring by using the matching component; a plurality of the feeding pipes are installed at different positions on the special-shaped ring through the matching component.

[0010] By adopting the above technical solution, the distance from the circumference of the special-shaped ring to the rotating shaft continuously changes, and a plurality of feeding pipes are installed at different positions on the special-shaped ring through the matching component, enabling materials in different forms to be added and quickly dispersed at different positions, avoiding the problems of premature reaction and blockage between materials, and further improving the feeding efficiency and production safety.

[0011] Preferably, the matching component includes a connecting ring, a sliding ring and a connecting pipe. The feeding hole is a waist-shaped hole. The sliding ring is slidably arranged in the feeding hole. The sliding ring is slidably connected to the polymerization top cover. One end of the feeding pipe close to the feeding hole is fixedly installed on the sliding ring; a moving ring groove is formed in the peripheral wall of the special-shaped ring. The connecting ring is slidably connected to the special-shaped ring and can move along the moving ring groove. One end of the connecting pipe is connected to the connecting ring and the other end is connected to the sliding ring. When the special-shaped ring rotates, the connecting ring moves in the moving ring groove, and the materials in the feeding pipe are discharged into the polymerization tank through the connecting pipe.

[0012] By adopting the above technical solution, the rotation of the special-shaped ring can drive the connecting ring to move in the moving ring groove, and then drive the sliding ring to slide in the waist-shaped hole through the connecting pipe. This design enables the position of the feeding pipe to change with the rotation of the special-shaped ring, thereby realizing the uniform distribution of materials. It ensures the smoothness of material transmission and further improves the feeding efficiency.

[0013] Preferably, a protective sliding sleeve is further arranged on the feeding pipe, and a protective sliding frame is arranged on the polymerization top cover. The protective sliding sleeve is slidably connected to the protective sliding frame. When the sliding ring moves in the feeding hole, the protective sliding sleeve synchronously slides on the protective sliding frame.

[0014] By adopting the above technical solution, the provisions of the protective sliding sleeve and the protective sliding frame can effectively reduce the wear of the feeding pipe during movement and improve the service life of the feeding pipe. At the same time, the sliding fit between the protective sliding sleeve and the protective sliding frame ensures the stability of the feeding pipe when moving with the sliding ring, avoiding offset or jamming caused by external interference, thereby enhancing the reliability of the entire polymerization device during the feeding process.

[0015] Preferably, a plurality of the special-shaped rings are provided. The special-shaped ring close to the polymerization top cover is connected to the feeding pipe through a matching component, and the remaining special-shaped rings are sequentially installed on the rotating shaft along the axis direction of the rotating shaft; the auxiliary uniformity component further includes a mixing plate, a plurality of connecting rods, and a plurality of sealing and resetting components. The connecting rods are installed on the inner wall of the polymerization tank, and the mixing plate is installed on the connecting rods through the sealing and resetting components; the mixing plate can abut against the outer peripheral wall of the special-shaped ring and can approach or move away from the rotating shaft.

[0016] By adopting the above technical solution, the provision of a plurality of 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 close to the polymerization top cover is connected to the feeding pipe through a matching component, ensuring that the material can be immediately guided to a suitable position after being discharged from the feeding pipe, avoiding material accumulation or uneven distribution. The remaining special-shaped rings are sequentially installed along the axis direction of the rotating shaft, further enhancing the fluidity and mixing uniformity of the material in the polymerization tank. The mixing plate in the auxiliary uniformity component is installed on the connecting rods through the sealing and resetting components, and can abut against the outer peripheral wall of the special-shaped ring when the special-shaped ring rotates, and at the same time approach or move away from the rotating shaft under the action of the sealing and resetting components and the special-shaped ring, 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.

[0017] Preferably, the sealing and resetting component includes a stabilizing ring, two reset springs, and a sealing telescopic tube. The stabilizing ring is slidably sleeved on the connecting rod in a matching manner. Both of the two reset springs are sleeved on the connecting rod and are respectively arranged on both sides of the stabilizing ring. One end of each 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 fixedly 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, and the end wall of the mixing plate is fixedly connected to the outer wall of the sealing telescopic tube. The mixing plate and the stabilizing ring are symmetrically arranged on the inner and outer sides of the sealing telescopic tube.

[0018] By adopting the above technical solutions, the setting of the sealing and resetting member can achieve the stable resetting and sealing effect of the mixing plate. Specifically, the sliding fit of the stabilizing ring on the connecting rod and the elastic action of the two reset springs ensure that the mixing plate can automatically reset after contacting the special-shaped ring, avoiding irreversible displacement of the mixing plate due to external forces. At the same time, the setting of the sealing telescopic tube effectively prevents material leakage, and its sealed connection with the inner wall of the polymerization tank body and the end of the connecting rod further improves 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.

[0019] Preferably, a contact guiding arc plate is arranged on one side of the mixing plate close to the special-shaped ring, and there are always gaps between both ends of the contact guiding arc plate and the special-shaped ring.

[0020] By adopting the above technical solutions, a contact guiding arc plate is arranged on one side of the mixing plate close to the special-shaped ring, and there are always gaps between both ends of the contact guiding arc plate and the special-shaped ring, which can effectively avoid abrasion caused by direct contact between the mixing plate and the special-shaped ring. At the same time, it ensures that during the rotation of the special-shaped ring, the material is more evenly distributed under the guidance of the contact guiding arc plate, thereby improving the mixing effect and reducing equipment wear.

[0021] Preferably, the special-shaped ring is oval, the minimum distance from the special-shaped ring to the rotating shaft is the distance from the short-axis focus of the special-shaped ring to the rotating shaft, and the maximum distance from the special-shaped ring to the rotating shaft is the distance from the long-axis focus of the special-shaped ring to the rotating shaft.

[0022] By adopting the above technical solutions, the oval special-shaped ring can periodically change the relative distance from the rotating shaft during rotation. This design enables the feeding pipe installed on the special-shaped ring to achieve periodic position changes through the matching components, thereby forming a more uniform distribution effect when the material enters the polymerization tank body. Specifically in this solution, the short-axis focus and long-axis focus of the special-shaped ring respectively determine its minimum and maximum distances from the rotating shaft, and this feature further optimizes the position change range of the feeding pipe, improves the uniformity of material mixing, and thus enhances the overall feeding efficiency of the polymerization device.

[0023] Preferably, the diameters of multiple said feeding pipes are inconsistent.

[0024] By adopting the above technical solutions, the inconsistent diameters of multiple feeding pipes enable materials with different forms or flow requirements to be transported through the adapted feeding pipes. This design can improve the accuracy of material transmission, reduce material residue and mixing during the feeding process, thereby avoiding channel blockage and further enhancing the feeding efficiency of the polymerization device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: The independent feeding channel design for materials in different forms can avoid the problem of channel blockage caused by mixing reaction between liquid materials and granular or powdery materials during the feeding process, thereby significantly improving the feeding efficiency of the polymerization device; The distance from the circumference of the special-shaped ring to the rotating shaft changes continuously. 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, and further improving feeding efficiency and production safety; The mixing plate in the auxiliary homogenization component is installed on the connecting rod through the sealing reset part, which can contact the outer peripheral wall of the special-shaped ring when the special-shaped ring rotates, and at the same time, it is close to or away from the rotating shaft under the action of the sealing reset part and the special-shaped ring, so as to dynamically adjust and mix the materials, 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. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a polymerization device for safe production of latex. Figure 1 and Figure 2, The polymerization device for the safe production of latex includes a polymerization tank body 1. The polymerization tank body 1 is placed on the ground. A polymerization top cover 2 is installed on the top of the polymerization tank body 1. A rotating shaft 3 inserted into the interior of the polymerization tank body 1 is provided on the polymerization top cover 2. 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 inside the polymerization tank body 1 to mix the materials inside the polymerization tank body 1.

[0033] At least two feeding components 4 are provided on the polymerization top cover 2. In this embodiment, three feeding components 4 are provided. The three feeding components 4 are respectively arranged on the polymerization top cover 2, and each feeding component 4 allows materials of the same form to pass through; the feeding component 4 includes a feeding pipe 41. A feeding hole 21 is opened on the polymerization top cover 2. One end of the feeding pipe 41 is inserted into the feeding hole 21, and the feeding pipe 41 is communicated with the inner cavity of the polymerization tank body 1 through the feeding hole 21; the diameters of the multiple feeding pipes 41 are inconsistent. In this embodiment, the feeding pipe 41 with the smallest diameter is used to transport liquid materials, the feeding pipe 41 with the largest diameter is used to transport granular materials, and the feeding pipe 41 with the intermediate diameter is used to transport powder materials.

[0034] The design of independent feeding channels for materials of different forms is realized, avoiding the problem of channel blockage caused by the mixing reaction of liquid materials and granular or powdery materials during the feeding process, thereby significantly improving the feeding efficiency of the polymerization device.

[0035] Refer to Figure 2 and Figure 3 , An auxiliary uniform component 5 is arranged inside the polymerization tank body 1. The auxiliary uniform component 5 includes a special-shaped ring 51. In this embodiment, multiple special-shaped rings 51 are provided. The multiple special-shaped rings 51 are sequentially and fixedly installed on the rotating shaft 3 along the axial direction of the rotating shaft 3; in this embodiment, the special-shaped ring 51 is oval. 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.

[0036] The distance from the circumference of the special-shaped ring 51 to the rotating shaft 3 continuously changes. 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. A matching component 6 is arranged between the feeding pipe 41 and the special-shaped ring 51 located at the top of the rotating shaft 3. During the synchronous rotation of the special-shaped ring 51 with the rotating shaft 3, the feeding pipe 41 continuously connects with the special-shaped ring 51 by using the matching component 6; the multiple feeding pipes 41 are installed at different positions of the special-shaped ring 51 through the matching component 6.

[0037] 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 on the soft sealing material for the feeding tube 41 to move, and the feeding tube 41 can open the notch, and the notch is closed where there is no feeding tube 41. Since 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 matching component 6, the special-shaped ring 51 rotates synchronously with the rotating shaft 3, and the feeding tube 41 reciprocates in the length direction of the feeding hole 21, so that materials of different forms can be added at different positions and quickly dispersed, avoiding premature reaction and blockage between materials, and further improving feeding efficiency and production safety.

[0038] The mating component 6 includes a sliding ring 62, which is slidably set in the feeding hole 21, and the sliding ring 62 is slidably connected to the polymer top cover 2. The end of the feeding tube 41 close to the feeding hole 21 is fixedly installed on the sliding ring 62; when the sliding ring 62 moves 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 43 is installed on the polymer top cover 2 by bolts, and the protective sleeve 42 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.

[0039] A movable annular groove 52 is provided on the peripheral wall of the special-shaped ring 51. The special-shaped ring 51 is located in the movable annular 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 circumferential direction of the movable annular 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 and the feeding pipe 41 are connected. 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 annular 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.

[0040] 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, a plurality of connecting rods 54 and a plurality of sealing reset parts 55. The connecting rod 54 is installed on the inner wall of the polymerization tank body 1 by bolts, and the mixing plate 53 is installed on the connecting rod 54 by the sealing reset part 55; the mixing plate 53 can contact 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.

[0041] The seal reset member 55 includes a stabilizing ring 551, two reset springs 552, and a seal telescopic tube 553. The stabilizing ring 551 is adaptively sleeved and slidably arranged on the connecting rod 54. The two reset springs 552 are both sleeved on the connecting rod 54 and are respectively arranged on both sides of the stabilizing ring 551. One end of the reset 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.

[0042] The seal telescopic tube 553 is sleeved on the two reset springs 552. One end of the seal telescopic tube 553 is hermetically 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 seal telescopic tube 553. The end wall of the mixing plate 53 is fixedly connected to the outer wall of the seal telescopic tube 553. The mixing plate 53 and the stabilizing ring 551 are symmetrically arranged on the outer and inner sides of the seal 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 seal telescopic tube 553 to achieve sealing.

[0043] A contact guiding arc plate 531 is arranged on one side of the mixing plate 53 close to the special-shaped ring 51, and there is always a gap between both ends of the contact guiding arc plate 531 and the special-shaped ring 51. During the rotation of the special-shaped ring 51, the long axis of the special-shaped ring 51 contacts the contact guiding arc plate 531. The contact guiding arc plate 531 smoothly guides the long axis of the special-shaped ring 51 to the mixing plate 53. At this time, the mixing plate 53 moves away from the rotating shaft 3 under the action of the special-shaped ring 51 to stir the material. When the long axis of the special-shaped ring 51 rotates out of the contact guiding arc plate 531, the mixing plate 53 moves closer to the rotating shaft 3 again under the action of the reset spring 552 to stir the material again.

[0044] The implementation principle of a polymerization device for the 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 pipe 41 is limited by the inner wall of the feeding hole 21. Therefore, the connecting ring 61 slides along the moving ring groove 52. However, due to the continuous change in the inner diameter of the special-shaped ring 51, the sliding ring 62 drives the feeding pipe 41 to move in the feeding hole 21, and the connecting pipe 63 also moves reciprocally, enabling materials in different forms to be added at different positions and quickly dispersed, avoiding premature reactions and blockage problems between materials, and further improving the feeding efficiency and production safety.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
