Description

Technical Field

[0001] The present application relates to the technical field of hydrophilic resin preparation, and in particular to a continuous polymerization device. Background Art

[0002] Polymerization is a key method for preparing hydrophilic resins. This involves converting a monomeric reaction solution into a gel-like solid phase to form a hydrophilic resin. This method typically involves a long, horizontal conveyor line and the use of UV lamps to gradually polymerize the reaction solution. However, this method results in lower product quality and higher costs. Utility Model Content

[0003] The present application aims to address the existing problems of low quality and high cost in the polymerization of hydrophilic resins. Therefore, the present application provides a continuous polymerization apparatus that utilizes exhaust ducts and cooling equipment to control the polymerization temperature, thereby improving the quality of the hydrophilic resin. Furthermore, the highly structured, multi-layered first conveyor line minimizes floor space and reduces costs.

[0004] The embodiment of the present application provides a continuous polymerization device for continuously bagging a reaction solution to prepare a hydrophilic resin, comprising a first conveying line, and a first ultraviolet lamp, an exhaust pipe, and a cooling device arranged above the first conveying line;

[0005] The first conveying line is used to receive and continuously move the continuously bagged reaction solution, and to polymerize the reaction solution under the irradiation of the first ultraviolet lamp to form a hydrophilic resin;

[0006] The exhaust pipe is provided with a plurality of exhaust ports toward the first conveying line, and the exhaust ports are located above the first ultraviolet lamp;

[0007] The cooling device is provided corresponding to the first ultraviolet lamp and is used to cool the first ultraviolet lamp;

[0008] The first conveyor line is provided with multiple layers, and the multiple layers of the first conveyor lines are arranged in sequence along the height direction. A flipping component is provided between adjacent first conveyor lines. The flipping component is used to flip and move the continuous bagged reaction liquid between two adjacent first conveyor lines, so that the front and back of the continuous bagged reaction liquid are alternately placed on the two adjacent first conveyor lines.

[0009] By adopting the above technical solution, the first ultraviolet lamp is cooled by a cooling device to prevent the large amount of heat generated by the lamp from being dissipated and causing the polymerization environment to heat up rapidly. The polymerization environment is also cooled as a whole by an exhaust duct, taking into account the heat dissipation of the lamp and the heat dissipation of the polymerization reaction, to avoid the reaction liquid from heating up too quickly locally, resulting in uneven polymerization, affecting the quality of the finished product, and even overheating causing safety problems, thereby improving the quality of the hydrophilic resin; at the same time, by arranging multiple layers of the first conveyor line in sequence along the height direction, that is, utilizing the height layout, the overall device footprint can be effectively controlled, thereby reducing costs; and, by cooperating with the flipping component, the front and back sides of the continuously bagged reaction liquid are alternately illuminated, further improving the polymerization uniformity and improving the quality of the hydrophilic resin.

[0010] In some embodiments, the flipping assembly includes a guide roller, which is connected to a motor and rotates under the drive of the motor, so that the continuously bagged reaction liquid is flipped from the lower first conveyor line through the roller surface of the guide roller and moved to the upper first conveyor line.

[0011] By adopting the above technical solution, the continuous bagged reaction liquid is turned over and moved by guiding the drum surface of the guide roller, which has a simple structure and improves the reliability of the turning and movement, thereby improving the reliability and quality of the polymerization preparation.

[0012] In some embodiments, the flipping assembly also includes a guide plate and a limit plate, the guide plate having an arc-shaped guide surface adapted to the cylinder surface of the guide roller, the guide surface of the guide plate and the cylinder surface of the guide roller being used to cooperate with each other to clamp the continuously bagged reaction liquid; the limit plate is arranged at both ends of the guide roller and connected to the edge of the guide surface of the guide plate.

[0013] By adopting the above technical solution, the guide surface of the guide plate and the cylinder surface of the guide roller are matched, and the limit plate is matched with the end of the guide roller, which further improves the reliability of the flipping movement, has a simple structure, and effectively controls the cost.

[0014] In some embodiments, the conveying surface of the first conveying line is provided with a plurality of heat dissipation holes.

[0015] By adopting the above technical solution, the polymerization heat can be quickly dissipated from the bottom of the first conveyor line, further improving the heat dissipation effect of the device, thereby improving the polymerization quality and safety; and especially when the reaction liquid is still liquid, if the bagged reaction liquid leaks, the liquid at the leakage location can be discharged quickly, reducing the impact on the entire first conveyor line and improving maintenance convenience.

[0016] In some embodiments, corridors are provided on the sides of the first conveying line on each floor, and the corridors on multiple floors are connected by stairs, which are provided at the ends of the first conveying line on each floor.

[0017] The above technical solution facilitates the observation of the polymerization process of the continuous bagged reaction liquid and the maintenance of each layer of equipment.

[0018] In some embodiments, a stabilization unit is connected to the front end of the first conveying line at the bottom layer, and the stabilization unit includes a second conveying line and a second ultraviolet lamp arranged above the second conveying line.

[0019] By adopting the above technical solution, through the cooperation of the second conveyor line, the second ultraviolet lamp and the first conveyor line and the first ultraviolet lamp at the bottom layer, the reaction liquid entering the continuous polymerization device has a longer polymerization reaction time before flipping, so that the state is stabilized before the first flipping, that is, the liquid is initially changed into a gel state, avoiding the reaction liquid from shaking significantly in the bag during the flipping process and moving away from its original position, resulting in the generated hydrophilic resin having low quality or even being unable to be flipped and moved.

[0020] In some embodiments, a heat dissipation conveying line is connected above the first conveying line on the top layer through the flip assembly, and the exhaust duct is provided above the heat dissipation conveying line.

[0021] The above technical solution is adopted to improve the heat dissipation efficiency of the polymerization product, so that the polymerization product can enter the final stable state more quickly, facilitate rapid entry into the subsequent process flow, and improve overall efficiency.

[0022] In some embodiments, a plurality of the first ultraviolet lamps are provided, and the plurality of the first ultraviolet lamps are sequentially arranged along the length direction of the first conveying line;

[0023] The width of the first ultraviolet lamp is adapted to the width of the first conveying line.

[0024] Other features and corresponding beneficial effects of the present application are described in the latter part of the specification, and it should be understood that at least some of the beneficial effects become obvious from the description in the specification of the present application.

[0042] Figure 2 This is a schematic top view of the structure of an embodiment of the present application, in which the exhaust vents 131 and the first ultraviolet lamp 120 of each layer are omitted;

[0044] The embodiment of the present application provides a continuous polymerization device, which is particularly suitable for preparing hydrophilic resins from continuously bagged reaction liquids and can realize continuous polymerization reactions of continuously bagged reaction liquids.

[0045] The device includes a first conveying line 110 , and a first ultraviolet lamp 120 , an exhaust pipe 130 and a cooling device arranged above the first conveying line 110 .

[0046] The first conveyor line 110 is used to receive and continuously move the continuously bagged reaction solution, and polymerize the reaction solution to form a hydrophilic resin under the irradiation of the first ultraviolet lamp 120. The preparation of hydrophilic resin using ultraviolet polymerization is a conventional technique in the art, and those skilled in the art can prepare the reaction solution according to the preparation requirements.

[0047] In one embodiment, a plurality of first UV lamps 120 are provided, and the plurality of first UV lamps 120 are sequentially arranged along the length of the first conveyor line 110. Preferably, the width of the first UV lamps 120 is adapted to the width of the first conveyor line 110, so that the continuously bagged reaction solution is more comprehensively illuminated, thereby improving product quality.

[0048] A cooling device is provided corresponding to the first UV lamp 120 and is used to cool the first UV lamp 120 to prevent the large amount of heat generated by the lamp from being dissipated, causing a rapid temperature rise in the polymerization environment, resulting in excessive local temperature rise in the reaction solution, uneven polymerization, and affecting the quality of the finished product. The cooling device can be an air conditioner.

[0049] The exhaust duct 130 is provided with a plurality of exhaust ports 131 facing the first conveyor line 110, and the exhaust ports 131 are located above the first ultraviolet lamp 120. The exhaust duct 130 is used to cool the polymerization environment as a whole, taking into account both the heat dissipation of the lamp and the heat dissipation of the polymerization reaction, thereby avoiding local excessive temperature rise of the reaction liquid, resulting in uneven polymerization, affecting the quality of the finished product, and even overheating causing safety problems, thereby improving the quality of the hydrophilic resin.

[0050] In one embodiment, the first conveyor line 110 is configured with multiple layers, each arranged sequentially along the height direction. This height-based layout effectively controls the footprint of the system, thereby reducing costs. Furthermore, the saved floor space can be used to install other process equipment, enabling direct docking and centralized production, reducing transit and transportation routes, and thereby reducing overall process costs for the hydrophilic resin, while improving production efficiency and the quality of the final product.

[0051] In one embodiment, a flipping assembly 140 is provided between adjacent first conveyor lines 110. The flipping assembly 140 is used to flip and move the continuously bagged reaction liquid between the two adjacent first conveyor lines 110, so that the front and back sides of the continuously bagged reaction liquid are alternately placed on the two adjacent first conveyor lines 110, that is, the front and back sides are alternately illuminated, further improving the polymerization uniformity and improving the quality of the hydrophilic resin.

[0052] In one embodiment, the conveying surface of the first conveyor line 110 is provided with a plurality of heat dissipation holes, allowing polymerization heat to quickly escape from the bottom of the first conveyor line 110, further enhancing the heat dissipation effect of the device, thereby improving polymerization quality and safety. Furthermore, if the bagged reaction solution leaks while the reaction solution is still liquid, the liquid can be quickly drained from the leak site, reducing the impact on the entire first conveyor line 110 and improving maintenance convenience.

[0053] In one embodiment, a corridor 150 is set up on the side of each layer of the first conveyor line 110, and the multiple layers of corridors 150 are connected by stairs 160. The stairs 160 are set at the end of the first conveyor line 110 on each layer, which facilitates the observation of the continuous bagging reaction liquid polymerization process and the maintenance of the equipment on each layer.

[0054] Preferably, the driving motor 111 of the first conveyor line 110 is arranged on the corridor 150, so as to further facilitate maintenance.

[0055] Preferably, guardrails 151 are provided on the sides of the corridor 150 to improve personnel safety.

[0056] In one embodiment, the front end of the first conveyor line 110 at the bottom layer is connected to a stabilizing unit, which includes a second conveyor line 170 and a second ultraviolet lamp arranged above the second conveyor line 170. That is, through the cooperation of the second conveyor line 170, the second ultraviolet lamp, and the first conveyor line 110 and the first ultraviolet lamp 120 at the bottom layer, the reaction liquid entering the continuous polymerization device has a longer polymerization reaction time before flipping, so that the state is stabilized before the first flipping, that is, the liquid is initially changed into a gel state, to avoid the reaction liquid from shaking significantly in the bag during the flipping process and moving away from its original position, resulting in the generated hydrophilic resin having low quality or even unable to be flipped and moved.

[0057] In one embodiment, a heat dissipation conveyor line is connected above the top first conveyor line 110 through a flip assembly 140, and an exhaust duct 130 is provided above the heat dissipation conveyor line to improve the heat dissipation efficiency of the polymer product, so that the polymer product can enter the final stable state faster, facilitate rapid entry into subsequent process flow, and improve overall efficiency.

[0058] See Figure 4 , Figure 4 It is an enlarged structural diagram of the flip assembly 140 in the embodiment of the present application.

[0059] In one embodiment, the flipping assembly 140 includes a guide roller 141, which is connected to a motor and rotates when driven by the motor, so that the continuously bagged reaction liquid is flipped from the lower first conveyor line 110 through the roller surface of the guide roller 141 and moved to the upper first conveyor line 110. The structure is simple and the reliability of the flipping movement is improved, thereby improving the reliability and quality of the polymerization preparation.

[0060] In one embodiment, the flipping assembly 140 also includes a guide plate 142, which has an arc-shaped guide surface that is compatible with the cylinder surface of the guide roller 141. The guide surface of the guide plate 142 and the cylinder surface of the guide roller 141 are used to cooperate with each other to clamp the continuous bagged reaction liquid, further improving the reliability of the flipping movement, and the structure is simple, effectively controlling the cost.

[0061] In one embodiment, the flipping assembly 140 also includes a limit plate 143, which is arranged at both ends of the guide roller 141 and connected to the edge of the guide surface of the guide plate 142, thereby preventing the continuous bagged reaction liquid from deviating during the flipping process, further improving the reliability of the flipping movement, and having a simple structure, effectively controlling the cost.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
