Description

Technical Field

[0001] The invention relates to the technical field of continuous production of water-based acrylic resin, and more specifically to a tubular reaction device for continuous production of water-based acrylic resin. Background Art

[0002] As an important chemical material, water-based acrylic resin is widely used in coatings, adhesives, inks and other fields. With the continuous improvement of environmental protection requirements, its market demand is growing. In the production process of water-based acrylic resin, the efficiency of the reaction process and the stability of product quality are crucial.

[0003] At present, the tubular reaction device used for the continuous production of water-based acrylic resin has an inner cavity of basically fixed length. In actual production, the water-based acrylic resin presents a reaction state in which the front end is relatively viscous and the rear end is relatively sparse in the tubular reaction device. On the one hand, due to the viscosity of the reaction front end, the flow resistance of the material in the tubular reaction device is large, and it is difficult to distribute and react evenly. This makes it difficult to fully carry out the reaction, which easily leads to local overreaction or incomplete reaction, thereby affecting the quality of the product. For example, some polymer molecules may be excessively aggregated at the front end of the reaction, resulting in uneven molecular weight distribution of the product, affecting the performance of the product. On the other hand, the sparse state at the rear end of the reaction makes the reaction efficiency low. Due to the relatively low concentration of the material at the rear end of the reaction, the reaction speed is slow, and it takes a long time to complete the reaction. This not only increases the production cycle, but also reduces the production efficiency. In order to cope with this situation, the existing tubular reaction device often needs to react repeatedly, or complete the reaction by connecting multiple tubular reaction devices in series. However, this method is not only time-consuming and labor-intensive, but also increases production costs. For example, during repeated reactions, the reaction conditions need to be adjusted multiple times, which increases the complexity and uncertainty of the operation; and connecting multiple tubular reaction units in series requires more equipment investment and maintenance costs.

[0004] In summary, the existing tubular reaction device cannot be highly adapted to the reaction state of water-based acrylic resin, resulting in low production efficiency and difficulty in ensuring product quality. Therefore, it is of great practical significance to develop a tubular reaction device that can be optimized according to the reaction state of water-based acrylic resin. In view of this, we propose a tubular reaction device for continuous production of water-based acrylic resin. Summary of the invention

Since the external thread groove of the first screw is matched with the internal thread groove of the inner wall of the inner sleeve block of the second sleeve, the first screw is rotated to eject the second sleeve. When the first screw rotates, the linear slide groove provided on the outer wall of the first screw is slidably plugged with the linear slide bar provided on the inner wall of the second screw. Therefore, the second screw is driven to rotate synchronously while the first screw rotates. When the second screw rotates, since the external thread groove of the second screw is matched with the internal thread groove of the inner wall of the inner sleeve block of the third sleeve, the second screw is rotated to eject the third sleeve. When the second screw rotates, the linear slide groove provided on the outer wall of the second screw is plugged with the linear slide bar provided on the inner wall of the second screw. The sliding groove is slidably connected with the linear sliding bar arranged on the inner wall of the third screw, so the third screw will be driven to rotate synchronously when the second screw rotates; when the third screw rotates, since the external thread groove of the third screw is adapted to the internal thread groove of the inner sleeve block of the fourth sleeve, the third screw rotates to eject the fourth sleeve. Therefore, when the first sleeve, the second sleeve, the third sleeve and the fourth sleeve are all ejected, the internal area of ​​the reaction chamber is lengthened, otherwise the internal area of ​​the reaction chamber is reduced.

[0046] like Figures 1 to 18 As shown, the present invention relates to a tubular reaction device for continuous production of water-based acrylic resin, comprising a raw material tank 1, a frame 2 is provided on one side of the raw material tank 1, a mounting frame 3 is provided on the frame 2 near one end of the raw material tank 1, a driving mechanism 4 is provided inside the mounting frame 3, a dual-state reaction tube group 5 is provided on the frame 2, a rotating tube 6 is provided on the top of the mounting frame 3, an input end of the rotating tube 6 is connected to an output end of the raw material tank 1 through a hose 7, an input end of the dual-state reaction tube group 5 is rotatably connected to an end of the rotating tube 6 away from the hose 7, an output end of the driving mechanism 4 is connected to the dual-state reaction tube group 5, an end of the dual-state reaction tube group 5 away from the rotating tube 6 is provided with a resin whipping mechanism 8, a heating half-tube 9 is provided around the outer wall of the dual-state reaction tube group 5, a heat preservation pump 10 is provided on the outer wall of the mounting frame 3, and both ends of the heating half-tube 9 are connected to the heat preservation pump 10. The present invention improves the structure of the existing tubular reaction device, arranges a dual-state reaction tube group 5 on a frame 2, connects a raw material tank 1 through a hose 7, and raw materials such as acrylic acid monomer, initiator, emulsifier, deionized water, etc. in the raw material tank 1 enter the dual-state reaction tube group 5 through the hose 7 to perform tubular reaction, and drives the dual-state reaction tube group 5 through a driving mechanism 4 to form a viscous reaction state or a sparse reaction state, thereby adapting to different states of the water-based acrylic resin at the front and rear ends in the tubular reaction. At the front end of the reaction, the reaction tube group can be adjusted to a viscous state, so that the material can fully react under high viscosity and improve the reaction rate; at the rear end of the reaction, it is adjusted to a sparse state, reducing the flow resistance of the material, accelerating the reaction process, and reducing the reaction time. The present invention has the advantages of improving reaction efficiency and product quality.

[0047] The present invention improves the tubular reaction device used in the production of existing water-based acrylic resin. Since the inner cavity of the existing reaction device is basically fixed in length, in actual production, the water-based acrylic resin presents a reaction state in which the front end is relatively viscous and the rear end is relatively sparse in the tubular reaction device. On the one hand, due to the viscosity of the reaction front end, the flow resistance of the material in the tubular reaction device is large, and it is difficult to distribute and react evenly; making it difficult to fully carry out the reaction, it is easy to cause local overreaction or incomplete reaction, thereby affecting product quality. On the other hand, the sparse state of the reaction rear end makes the reaction efficiency low. Since the concentration of the material at the reaction rear end is relatively low, the reaction speed is slow, and it takes a long time to complete the reaction. This not only increases the production cycle, but also reduces the production efficiency. In order to cope with this situation, an adjustable dual-state reaction tube group 5 is set to adapt to the above two reaction states respectively to improve its reaction efficiency.

[0048] The existing tubular reaction device needs to react repeatedly, and the reaction is completed by connecting multiple tubular reaction devices in series. The materials need to be transferred in multiple devices, and the reaction continuity is poor. Compared with the existing tubular reaction device, the present invention realizes the front-end and rear-end reactions of the water-based acrylic resin in the dual-state reaction tube group 5, and there is no need to transfer equipment. Therefore, the present invention has strong continuity and can efficiently realize continuous production.

[0049] In an embodiment of the present invention, the dual-state reaction tube group 5 includes a first screw 501, a second screw 502, a third screw 503, a first sleeve 504, a second sleeve 505, a third sleeve 506 and a fourth sleeve 507. The first screw 501 is connected to the driving mechanism 4, the second screw 502 is sleeved on the first screw 501, the third screw 503 is sleeved on the second screw 502, the first sleeve 504 is arranged on the frame 2, the second sleeve 505 is slidably arranged on the first sleeve 504, the third sleeve 506 is slidably arranged on the second sleeve 505, and the fourth sleeve 507 is slidably arranged on the third sleeve 506. The first screw 501 is rotatably arranged on the first sleeve 504, the second screw 502 is rotatably arranged on the second sleeve 505, the third screw 503 is rotatably arranged on the third sleeve 506, and the resin beating mechanism 8 is arranged on the fourth sleeve 507. The first sleeve 504, the second sleeve 505, the third sleeve 506 and the fourth sleeve 507 in the present invention are in a slidably plugged connection relationship with each other.

[0050] Sparse reaction state: refers to the first screw 501, the second screw 502 and the third screw 503 of the dual-state reaction tube group 5 driven by the driving mechanism 4 to rotate, and the first sleeve 504, the second sleeve 505, the third sleeve 506 and the fourth sleeve 507 are ejected, so that the volume of the reaction chamber is increased, which is suitable for the material reaction front end with a relatively sparse texture;

[0051] Viscous reaction state: refers to the first screw 501, the second screw 502 and the third screw 503 of the dual-state reaction tube group 5 driven by the driving mechanism 4 to rotate in opposite directions, shrinking the first sleeve 504, the second sleeve 505, the third sleeve 506 and the fourth sleeve 507, so that the volume of the reaction chamber is reduced, which is suitable for the material with a more viscous texture at the rear end of the reaction;

[0052] In an embodiment of the present invention, the outer walls of the first screw 501, the second screw 502 and the third screw 503 are all provided with external thread grooves 508, the inner walls of the second sleeve 505, the third sleeve 506 and the fourth sleeve 507 are all provided with inner sleeve blocks 509, the inner walls of the inner sleeve blocks 509 are provided with internal thread grooves 510, and the external thread grooves 508 are threadably matched with the internal thread grooves 510.

[0055] In the present invention, the first screw rod 501 is driven to rotate by the driving mechanism 4. Since the external thread groove 508 of the first screw rod 501 is adapted to the internal thread groove 510 of the inner wall of the inner sleeve block 509 of the second sleeve 505, the first screw rod 501 is rotated to eject the second sleeve 505. When the first screw rod 501 rotates, the line slide groove 513 provided on the outer wall of the first screw rod 501 is slidably plugged with the line slide bar 514 provided on the inner wall of the second screw rod 502. Therefore, when the first screw rod 501 rotates, the second screw rod 502 is driven to rotate synchronously.

[0056] When the second screw 502 rotates, the outer thread groove 508 of the second screw 502 is matched with the inner thread groove 510 of the inner wall of the inner sleeve block 509 of the third sleeve 506, so the second screw 502 rotates to eject the third sleeve 506. When the second screw 502 rotates, the line slide groove 513 provided on the outer wall of the second screw 502 is slidably plugged with the line slide bar 514 provided on the inner wall of the third screw 503, so the rotation of the second screw 502 will drive the third screw 503 to rotate synchronously;

[0057] When the third screw 503 rotates, since the external thread groove 508 of the third screw 503 is adapted to the internal thread groove 510 of the inner sleeve block 509 of the fourth sleeve 507, the third screw 503 rotates to eject the fourth sleeve 507. Therefore, when the first sleeve 504, the second sleeve 505, the third sleeve 506 and the fourth sleeve 507 are all ejected, the internal area of ​​the reaction chamber is lengthened, and vice versa. The internal area of ​​the reaction chamber is reduced. The present invention can flexibly adjust the reaction space to meet the space requirements of different reaction stages, improve the reaction efficiency and quality, and enhance the versatility and flexibility of the equipment.

Since the external thread groove 508 of the first screw 501 is adapted to the internal thread groove 510 of the inner wall of the inner sleeve block 509 of the second sleeve 505, the first screw 501 rotates to eject the second sleeve 505. When the first screw 501 rotates, since the line slide groove 513 provided on the outer wall of the first screw 501 is slidably plugged with the line slide bar 514 provided on the inner wall of the second screw 502, the second screw 502 will be driven to rotate synchronously while the first screw 501 rotates;

[0065] When the second screw 502 rotates, the outer thread groove 508 of the second screw 502 is matched with the inner thread groove 510 of the inner wall of the inner sleeve block 509 of the third sleeve 506, so the second screw 502 rotates to eject the third sleeve 506. When the second screw 502 rotates, the line slide groove 513 provided on the outer wall of the second screw 502 is slidably plugged with the line slide bar 514 provided on the inner wall of the third screw 503, so the rotation of the second screw 502 will drive the third screw 503 to rotate synchronously;

[0066] When the third screw 503 rotates, since the external thread groove 508 of the third screw 503 is adapted to the internal thread groove 510 of the inner sleeve block 509 of the fourth sleeve 507, the third screw 503 rotates to eject the fourth sleeve 507. Therefore, when the first sleeve 504, the second sleeve 505, the third sleeve 506 and the fourth sleeve 507 are all ejected, the internal area of ​​the reaction chamber is lengthened, otherwise the internal area of ​​the reaction chamber is reduced.

[0067] During the reaction, the present invention does not need to switch equipment, but only needs to switch the reaction form of the dual-state reaction tube group 5 to adapt the front-end reaction and the back-end reaction of the water-based acrylic resin, thereby realizing continuous production;

[0068] Secondly, according to the reaction state of the dual-state reaction tube group 5, the state of the resin whipping mechanism 8 is switched. When the inner area of ​​the reaction chamber is longer and the mixture is more sparse, or when the inner area of ​​the reaction chamber is shorter and the mixture is more viscous, the electric push rod 8031 ​​is driven to push the movable plug rod 8032 and the clutch gear 8033 to move, and the full-rotation gear 8022 or the adjustment gear 8023 is selected to mesh. When the clutch gear 8033 meshes with the adjustment gear 8023, the servo motor 8011 is driven to drive the worm 8012 to rotate, and the worm 8012 meshes with the worm wheel 8013. The worm gear 8013 rotates, and the movable plug rod 8032 and the clutch gear 8033 fixed thereto rotate. The clutch gear 8033 engages to drive the adjusting gear 8023 to rotate. The adjusting gear 8023 engages to drive the toothed groove 8025 and the beating block 8024 to rotate, thereby achieving size adjustment. The beating block 8024 is expanded to achieve the effect of expanding the beating area. Conversely, the beating block 8024 is retracted to achieve the effect of reducing the beating area. When the clutch gear 8033 engages with the full-rotation gear 8022, it drives the rotating frame 8021 to rotate as a whole, thereby achieving the whipping function.

[0069] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
