Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide cooling technology, and more specifically, to a polyacrylamide spiral stirring cooling device. Background Technology

[0002] The polyacrylamide spiral stirring and cooling device is a specialized piece of equipment designed for stirring and cooling during the polymerization process of polyacrylamide. This device achieves effective stirring and cooling of the polyacrylamide polymerization reaction through spiral stirring blades and a built-in cooling system. During the polymerization of polyacrylamide, once the reaction begins, the viscosity of the polymer system increases rapidly, posing a significant challenge to effective stirring. Because the polymer gel itself is a poor thermal conductor, the heat generated by the polymerization reaction is difficult to dissipate effectively from the gel, causing the system temperature to rise rapidly. As the temperature rises, the polymerization reaction rate accelerates further, releasing even more heat, which in turn exacerbates the temperature rise. This positive feedback mechanism gradually leads the polymerization reaction into an uncontrollable state, with continuously rising temperatures, accelerating reaction rates, and increasing heat release, creating a vicious cycle. This can not only lead to a decline in the quality of the polymerized product but also pose safety hazards, endangering production equipment and operators. Utility Model Content

[0026] 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 protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, this utility model provides a polyacrylamide spiral stirring and cooling device, including a barrel 1, a first fixing plate 3 fixedly installed inside the barrel 1, a rotating shaft 4 movably installed inside the first fixing plate 3, and one end of the rotating shaft 4 passing through the inside of the barrel 1. A second gear 26 is fixedly installed at one end of the rotating shaft 4. A box 27 is fixedly installed at the bottom of the barrel 1, a motor 17 is fixedly installed at the bottom of the box 27, and a first gear 15 is fixedly installed at the output end of the motor 17, and the first gear 15 and the second gear 16 are meshed.

[0028] A water outlet assembly is movably installed inside the rotating shaft 4, an inner cylinder 14 is fixedly installed inside the tank body 1, a stirring rod 28 is fixedly installed on the outer surface of the rotating shaft 4, and the stirring rod 28 is arranged in a circular array. A spiral blade 13 is fixedly installed on the outer surface of the rotating shaft 4.

[0029] The worker pours polyacrylamide into the inner cylinder 14, then turns on the motor 17. The motor 17 drives the first gear 15 to rotate inside the housing 27. Through the meshing of the teeth between the first gear 15 and the second gear 16, the first gear 15 drives the second gear 16 to rotate. The second gear 16 drives the rotating shaft 4 to rotate clockwise inside the first fixed plate 3 and the barrel 1. The rotating shaft 4 drives the spiral blade 13 to rotate inside the inner cylinder 14. Now the water outlet component is turned on, and the polyacrylamide is cooled through the water outlet component. When the polyacrylamide is slowly conveyed to the top of the inner cylinder 14 through the spiral blade 13, the rotating shaft 4 drives the stirring rod 28 to disperse the polyacrylamide, which is beneficial to the heat dissipation efficiency of the polyacrylamide. At this time, the polyacrylamide enters the interior of the barrel 1, thus completing the heat dissipation of the polyacrylamide.

[0030] Polyacrylamide is poured into the inner cylinder 14, and then the motor 17 is turned on. The motor 17 drives the first gear 15 to rotate inside the housing 27, which in turn drives the second gear 16 to rotate. The second gear 16 then drives the rotating shaft 4 to rotate clockwise inside the first fixed plate 3 and the barrel 1. The rotating shaft 4 drives the spiral blade 13 to rotate inside the inner cylinder 14. Now, the water outlet component is turned on to cool the polyacrylamide. As the polyacrylamide is slowly conveyed out of the top of the inner cylinder 14 by the spiral blade 13, the rotating shaft 4 drives the stirring rod 28 to disperse the polyacrylamide. Compared with traditional devices, this device uses a spiral blade to disperse the polyacrylamide. The interaction between blade 13 and water, through continuous agitation and mixing of polyacrylamide, increases the contact area and time between polyacrylamide and the water cooling medium. Simultaneously, stirring rod 28 disperses the material, further promoting heat exchange and significantly improving cooling efficiency. Water, as the cooling medium, circulates within the device; by adjusting its flow rate and temperature, the cooling process can be precisely controlled, ensuring the material is cooled within a suitable temperature range. Furthermore, the rotation of the spiral blades ensures uniform distribution of polyacrylamide, promoting internal heat transfer, preventing localized overheating or insufficient cooling, and enhancing cooling uniformity. Under the stirring of spiral blade 13, water is evenly distributed around the material, reducing the temperature gradient and further improving cooling efficiency and quality.

[0031] Among them, a limiting plate 29 is fixedly installed at the bottom of the barrel 1, a connecting rod 30 is movably installed inside the limiting plate 29, a collection box 11 is hinged to one end of the connecting rod 30, a limiting block 31 is fixedly installed at the other end of the connecting rod 30, a push rod 25 is fixedly installed on the back of the collection box 11, a water outlet pipe 23 is fixedly installed at the top of the barrel 1, a one-way valve 22 is fixedly installed inside the water outlet pipe 23, and universal wheels 26 are hinged around the bottom of the collection box 11.

[0032] Workers need to collect the cooled polyacrylamide. By holding the push rod 25, the collection box 11 and the casters 26 are pushed to the bottom of the barrel 1. The collection box 11 then drives the connecting rod 30 and the limiting block 31 through the inside of the limiting plate 29. Then, by holding the limiting block 31, the limiting plate 29 is rotated 90 degrees. Now, the one-way valve 22 is opened inside the outlet pipe 23, allowing the cooled polyacrylamide to enter the collection box 11 through the outlet pipe 23, thus completing the collection of polyacrylamide.

[0033] The cooled polyacrylamide needs to be collected. By holding the push rod 25, the collection box 11 and the casters 26 are pushed to the bottom of the barrel 1. The collection box 11 then drives the connecting rod 30 and the limiting block 31 through the inside of the limiting plate 29. Then, by holding the limiting block 31, the limiting plate 29 is rotated 90 degrees. Now, the one-way valve 22 is opened inside the water outlet pipe 23, allowing the cooled polyacrylamide to enter the collection box 11 through the water outlet pipe 23. Compared with traditional devices, this device, through the cooperation between the limiting plate 29, the connecting rod 30 and the limiting block 31, facilitates the limiting and fixing of the collection box 11. The collection box 11 collects the polyacrylamide, effectively preventing the material from scattering during stirring and cooling, reducing loss and ensuring the integrity of the material, which is convenient for subsequent collection and processing. At the same time, the design of this device focuses on the convenience of material discharge. There is a discharge port at the bottom or side. The cooled polyacrylamide can be easily discharged by rotating the spiral blades, simplifying the collection process, reducing the need for manual operation and improving the level of automation.

[0034] The water outlet assembly is movably installed inside the rotating shaft 4. The water outlet assembly includes a first connecting pipe 2 movably installed inside the rotating shaft 4. A water pump 21 is fixedly installed on the outer surface of the tank body 1. The output end of the water pump 21 is fixedly connected to the first connecting pipe 2. A water tank 7 is fixedly installed on the outer surface of the tank body 1. A second connecting pipe 6 is movably installed inside the water tank 7. One end of the second connecting pipe 6 is fixedly connected to the output end of the water pump 21.

[0035] The staff needs to turn on the water pump 21 to allow the water inside the inner cylinder 14 to enter the water pump 21 through the second connecting pipe 6, then through the water pump 21 into the first connecting pipe 2, and then through the first connecting pipe 2 into the first fixed plate 3, which facilitates the cooling of polyacrylamide and improves the cooling efficiency of polyacrylamide.

[0036] Among them, a fixing seat 18 is fixedly installed on the right side of the water tank 7, a fixing block 19 is movably installed inside the fixing seat 18, and a toolbox 8 is fixedly installed on the right side of the fixing block 19.

[0037] By holding the toolbox 8, the fixing block 19 is slowly placed into the fixing seat 18. The fixing seat 18 limits and fixes the fixing block 19. By adding the toolbox 8, it is convenient for the staff to take out and place maintenance tools inside the toolbox 8, and to maintain the device in a timely manner.

[0038] The inner diameter of the fixing seat 18 is equal to the outer diameter of the fixing block 19, and the inner surface of the fixing block 19 is smooth.

[0039] Since the inner diameter of the fixing base 18 is equal to the outer diameter of the fixing block 19, and the inner surface of the fixing block 19 is smooth, the fixing block 19 can be slowly inserted into the fixing base 18 by holding the toolbox 8, thus ensuring the installation efficiency of the toolbox 8.

[0040] A support block 12 is fixedly installed between the first fixing plate 3 and the first connecting pipe 2, and the support block 12 has two shapes of the same size.

[0041] Since the support block 12 has two identical shapes at the angle between the first fixing plate 3 and the first connecting pipe 2, the support block 12 can provide stable support for the first connecting pipe 2, ensuring the stability of the first connecting pipe 2 during use.

[0042] Among them, a support plate 5 is fixedly installed at the bottom of the barrel 1, and a second fixing plate 9 is fixedly installed between the two support plates 5. The second fixing plate 9 and the support plate 5 are in pairs, and there are two pairs in total at the bottom of the barrel 1.

[0043] Since the second fixing plate 9 and the support plate 5 are paired up, there are two sets at the bottom of the barrel 1. The cooperation between the second fixing plate 9 and the support plate 5 facilitates stable support for the barrel 1 and ensures the efficiency of cooling polyacrylamide by the barrel 1.

[0044] Among them, a reinforcing rib 10 is fixedly installed at the angle between the support plate 5 and the second fixing plate 9, and the reinforcing rib 10 is triangular in shape.

[0045] Since the reinforcing rib 10 is triangular in shape at the angle between the support plate 5 and the second fixing plate 9, and triangles have stability characteristics, the stability of the second fixing plate 9 and the support plate 5 is ensured during use.

[0046] Among them, a support base 20 is fixedly installed on the outer surface of the barrel 1, and the interior of the support base 20 has a U-shaped form.

[0047] Since the support base 20 is U-shaped on the outer surface of the barrel 1, it provides stable support for the water pump 21, reduces the shaking of the water pump 21 during use, and improves the stability of the water pump 21 during use.

[0048] The rotating shaft 4 has water outlet holes 24 inside, and the water outlet holes 24 are arranged in a circular array.

[0049] Since the water outlet 24 is arranged in a circular array inside the rotating shaft 4, when water enters the interior of the rotating shaft 4 through the first connecting pipe 2, it flows evenly inside the inner cylinder 14 through the rotating shaft 4, thereby improving the cooling efficiency of the polyacrylamide.

[0050] Working principle and usage process of this utility model:

[0051] The worker pours polyacrylamide into the inner cylinder 14, then turns on the motor 17. The motor 17 drives the first gear 15 to rotate inside the housing 27. Through the meshing of the teeth between the first gear 15 and the second gear 16, the first gear 15 drives the second gear 16 to rotate. The second gear 16 drives the rotating shaft 4 to rotate clockwise inside the first fixed plate 3 and the barrel 1. The rotating shaft 4 drives the spiral blade 13 to rotate inside the inner cylinder 14. Now the water outlet component is turned on, and the polyacrylamide is cooled through the water outlet component. When the polyacrylamide is slowly conveyed to the top of the inner cylinder 14 through the spiral blade 13, the rotating shaft 4 drives the stirring rod 28 to disperse the polyacrylamide, which is beneficial to the heat dissipation efficiency of the polyacrylamide. At this time, the polyacrylamide enters the interior of the barrel 1, thus completing the heat dissipation of the polyacrylamide.

[0052] Workers need to collect the cooled polyacrylamide. By holding the push rod 25, the collection box 11 and the casters 26 are pushed to the bottom of the barrel 1. The collection box 11 then drives the connecting rod 30 and the limiting block 31 through the inside of the limiting plate 29. Then, by holding the limiting block 31, the limiting plate 29 is rotated 90 degrees. Now, the one-way valve 22 is opened inside the outlet pipe 23, allowing the cooled polyacrylamide to enter the collection box 11 through the outlet pipe 23, thus completing the collection of polyacrylamide.
