Description

Technical Field

[0001] This utility model relates to the field of proportioning device technology, and in particular to a proportioning device for aqueous solution in polyacrylamide emulsion production. Background Technology

[0002] Aqueous solutions are the core carrier and the basis for performance control in the production of polyacrylamide emulsions. Their importance is evident throughout the entire production process and product application. They can uniformly dissolve acrylamide monomers, initiators, chelating agents, and other additives, avoiding uneven polymerization caused by excessively high local monomer concentrations, and providing a stable environment for the polymerization reaction.

[0003] In traditional polyacrylamide emulsion production aqueous solution proportioning devices, water is first added to the tank, and then powdered acrylamide is added to the mixing tank. When the operator adds acrylamide, a large amount of acrylamide tends to fall rapidly into the water in the tank, which does not allow sufficient time for the acrylamide to be wetted and dispersed by the liquid. This results in clumping on the liquid surface or forming "fish eyes" (a wet outer layer with a dry powder inside), which are difficult to disperse quickly. Consequently, this reduces the efficiency of the operator in proportioning and mixing the aqueous solution. Based on the above problems, there is a need to provide a polyacrylamide emulsion production aqueous solution proportioning device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for mixing aqueous solutions in the production of polyacrylamide emulsions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for preparing an aqueous solution for polyacrylamide emulsion production includes a tank body. A cover plate is provided on the top of the tank body. A feed hopper and a water inlet hopper are respectively fixedly connected through the top two sides of the cover plate. A circular hole is formed through the center of the top of the cover plate. A stirring rod is rotatably connected to the inside of the circular hole. A motor is installed on the top of the cover plate. A support plate is fixedly connected to the top of the cover plate. The motor is fixedly connected to one side of the support plate. The bottom end of the motor output shaft is fixedly connected to the top end of the stirring rod. A fixing plate is fixedly connected to the outside of the tank body. A first circular groove is formed through the fixing plate on one side of the tank body, and a second circular groove is formed through the fixing plate on the other side of the tank body. A U-shaped plate is provided inside the tank body. A rotating rod and a synchronous rotating rod are respectively fixedly connected to both sides of the U-shaped plate. The rotating rod is rotatably connected to the first circular groove, and the synchronous rotating rod is rotatably connected to the second circular groove.

[0006] By adopting the above technical solution, and by setting up a cover plate, a fixed plate, a rotating rod, a synchronous rotating rod, and a U-shaped plate, during the acrylamide feeding process, when the acrylamide enters the barrel from the feed hopper, it will fall to the inside of the U-shaped plate. At this time, the tilt angle of the U-shaped plate can be adjusted by rotating the rotating rod, thereby adjusting the falling speed of the acrylamide.

[0007] Preferably, a first sealed bearing is installed inside the circular hole, the stirring rod is rotatably connected to the circular hole through the first sealed bearing, a second sealed bearing is installed inside the first circular groove, the rotating rod is rotatably connected to the first circular groove through the second sealed bearing, a third sealed bearing is installed inside the second circular groove, and the synchronous rotating rod is rotatably connected to the second circular groove through the third sealed bearing.

[0008] By adopting the above technical solution, and by setting up a stirring rod and a first sealed bearing, the friction between the stirring rod and the cover plate during rotation can be reduced, increasing the rotation efficiency of the stirring rod. At the same time, it can also prevent dust and other impurities from entering the tank through the gap between the stirring rod and the cover plate, thus affecting product quality. By setting up a second sealed bearing and a third sealed bearing, the friction between the rotating rod and the synchronous rotating rod during rotation can be reduced, increasing the rotation efficiency of the rotating rod and the synchronous rotating rod.

[0009] Preferably, a locking sleeve is fixedly fitted on the outer side of the rotating rod, and several locking blocks are fixedly connected to the outer side of the locking sleeve. Two fixing rods are fixedly connected to one side of the fixing plate. Mounting sleeves are slidably fitted on the outer side of each of the two fixing rods. A slip ring is fixedly connected between the two mounting sleeves. Several slots are opened on the inner wall of the slip ring. The slip ring is slidably fitted on the outer side of the locking sleeve, and the locking blocks are adapted to the slots.

[0010] By adopting the above technical solution, by setting a locking sleeve, a mounting sleeve, a locking block, a locking groove, and a slip ring, the locking groove and the locking block can fix the U-shaped plate by docking, and by setting a fixing rod, the movement of the mounting sleeve can be guided.

[0011] Preferably, a spring is fixedly connected between the fixing plate and the mounting sleeve.

[0012] By adopting the above technical solution and setting a spring, the mounting sleeve can be made to increase the moving resistance and the reset moving speed.

[0013] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the fixing plate, and the size of the limiting plate is larger than the size of the inner side of the mounting sleeve.

[0014] By adopting the above technical solution and setting a limiting plate, when the mounting sleeve moves to the end of the fixing rod away from the fixing plate, the size of the limiting plate is larger than the size of the inner side of the mounting sleeve, thus preventing the mounting sleeve from falling off the fixing rod.

[0015] Preferably, a pressing plate is fixedly connected to the top of one side of the slip ring, and a handle is fixedly connected to the end of the rotating rod away from the fixed plate. The pressing plate has multiple anti-slip protrusions on one side, and an anti-slip sleeve is provided on the outside of the handle. The anti-slip sleeve is made of rubber and has anti-slip texture on its surface.

[0016] By adopting the above technical solutions, the friction of the pressing plate can be increased by setting anti-slip ridges, and the friction of the grip can be increased by setting anti-slip sleeves and anti-slip textures, thus preventing slippage.

[0017] Preferably, a discharge pipe is fixedly connected through the bottom of the barrel, a valve is installed at one end of the discharge pipe, and multiple support legs are fixedly connected to the bottom of the barrel.

[0018] By adopting the above technical solution, the material inside the barrel can be quickly discharged by setting up a discharge pipe, and the barrel can be supported by setting up support legs to keep the barrel at a certain distance from the ground. Setting up multiple support legs can increase the stability of the barrel.

[0019] Preferably, both the feed hopper and the water inlet hopper are hinged to have top covers, and a handle is installed on one side of the top cover.

[0020] By adopting the above technical solution and setting a top cover, dust and other impurities can be prevented from entering the barrel from the feed hopper and water inlet, thus affecting product quality. The top cover can be opened more easily and quickly by setting hinges and handles.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a cover plate, a fixing plate, a synchronous rotating rod, a rotating rod, and a U-shaped plate, allows the operator to rotate the rotating rod when adding acrylamide. The rotation of the rotating rod drives the U-shaped plate and the synchronous rotating rod to rotate. After the acrylamide enters the tank from the feed hopper, it falls onto the U-shaped plate. By changing the tilt angle of the U-shaped plate, the falling speed of the acrylamide can be adjusted, thereby preventing the acrylamide from falling into the water of the tank in a rapid and large amount. This ensures that the acrylamide has sufficient time to be dispersed by the stirring rod, shortens the stirring time, and increases the efficiency of the operator in mixing the aqueous solution.

[0022] 2. By setting a locking sleeve, fixing rod, mounting sleeve, slip ring, locking block and locking groove, the U-shaped plate can be fixed by the locking groove and locking block when it is rotated to any angle. When acrylamide falls onto the U-shaped plate, the U-shaped plate will not rotate at will, thus increasing the stability of the U-shaped plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 A device for preparing an aqueous solution for polyacrylamide emulsion production includes a barrel 1 made of transparent material. The barrel 1 has graduation marks on its outer side (not shown in the figure, as this is existing technology). A cover plate 2 is located on the top of the barrel 1. A feed hopper 3 and a water inlet hopper 4 are fixedly connected to the top of the cover plate 2 on both sides. Both the feed hopper 3 and the water inlet hopper 4 are hinged to a top cover. A handle is installed on one side of the top of the top cover. When adding material to the feed hopper 3 or water to the water inlet hopper 4, the operator holds the handle and pulls it to quickly open the cover plate 2 via the hinge. A circular hole is drilled through the center of the top of the cover plate 2. A stirring rod 9 is rotatably connected to the inside of the circular hole. A first sealing bearing is installed inside the circular hole. The stirring rod 9 is rotatably connected to the circular hole via the first sealing bearing, which reduces friction between the stirring rod 9 and the circular hole during rotation, extending the service life of the stirring rod 9.

[0027] Reference Figures 1-4 A motor 8, model YE3-90L-2, is installed on the top of the cover plate 2. A support plate 17 is fixedly connected to the top of the cover plate 2, and the motor 8 is fixedly connected to one side of the support plate 17. By setting the support plate 17, the motor 8 can be fixed, increasing the stability of the motor 8 during operation. The bottom end of the output shaft of the motor 8 is fixedly connected to the top end of the stirring rod 9. A fixing plate 5 is fixedly connected to the outside of the barrel 1. The fixing plate 5 and one side of the barrel 1 are both provided with a first circular groove, and the fixing plate 5 and the other side of the barrel 1 are both provided with a second circular groove. A U-shaped plate 7 is provided inside the barrel 1, and two parts are fixedly connected to the sides of the U-shaped plate 7 respectively. The rotating rod 6 and the synchronous rotating rod 19, and the inner dimension of the U-shaped plate 7 being larger than the bottom dimension of the feed hopper 3, ensure that all acrylamide added from the feed hopper 3 falls inside the U-shaped plate 7. When adding acrylamide, the operator rotates the rotating rod 6, which drives the U-shaped plate 7 to rotate. The rotation of the U-shaped plate 7 drives the synchronous rotating rod 19 to rotate. When the acrylamide enters the barrel 1 from the feed hopper 3, it will first fall inside the U-shaped plate 7. By rotating the rotating rod 6 to adjust the tilt angle of the U-shaped plate 7, the falling speed of the acrylamide can be quickly adjusted, ensuring that the product meets the specifications and reducing production costs.

[0028] Reference Figures 1-4 The rotating rod 6 is rotatably connected to the first circular groove. A second sealed bearing is installed inside the first circular groove. The rotating rod 6 is rotatably connected to the first circular groove through the second sealed bearing. The synchronous rotating rod 19 is rotatably connected to the second circular groove. A third sealed bearing is installed inside the second circular groove. The synchronous rotating rod 19 is rotatably connected to the second circular groove through the third sealed bearing. By setting the second and third sealed bearings, the friction force when the rotating rod 6 and the synchronous rotating rod 19 rotate can be reduced, and the rotation efficiency of the rotating rod 6 and the synchronous rotating rod 19 can be increased.

[0029] Reference Figure 1 , Figure 2 and Figure 4 A locking sleeve 13 is fixedly sleeved on the outside of the rotating rod 6. Several locking blocks are fixedly connected to the outside of the locking sleeve 13. Two fixing rods 10 are fixedly connected to one side of the fixing plate 5. An installation sleeve 11 is slidably sleeved on the outside of the two fixing rods 10. By setting the fixing rods 10, when the installation sleeve 11 slides on the outside of the fixing rods 10, the fixing rods 10 can guide the movement of the installation sleeve 11. A limit plate is fixedly connected to the end of the fixing rod 10 away from the fixing plate 5. The size of the limit plate is larger than the size of the inside of the installation sleeve 11. By setting the limit plate, the installation sleeve 11 is limited. When the installation sleeve 11 moves to the end of the fixing rod 10 near the handle 16, the limit plate will block the installation sleeve 11 from continuing to move, preventing the installation sleeve 11 from falling off the outside of the fixing rod 10.

[0030] Reference Figure 1 , Figure 2 and Figure 4 A spring 14 is fixedly connected between the fixed plate 5 and the mounting sleeve 11. When the slip ring 12 moves towards the fixed plate 5, the slip ring 12 moves, causing the mounting sleeve 11 to move. The moving mounting sleeve 11 compresses the spring 14, which increases the resistance to movement. When the slip ring 12 moves towards the handle 16, the spring 14 rebounds, accelerating the reset movement speed of the mounting sleeve 11 and the slip ring 12. A slip ring 12 is fixedly connected between the two mounting sleeves 11. Several slots are provided on the inner wall of the slip ring 12. The slip ring 12 is slidably sleeved on the outside of the locking sleeve 13. The locking block matches the slot. By setting the locking block, slot, and slip ring 12, when the U-shaped plate 7 rotates to a specified tilt degree, the slot and locking block fix the U-shaped plate 7 by docking. When acrylamide falls onto the U-shaped plate 7, the U-shaped plate 7 will not rotate arbitrarily, increasing the stability of the U-shaped plate 7.

[0031] Reference Figures 3-6 A pressing plate 15 is fixedly connected to the top of one side of the slip ring 12, and a handle 16 is fixedly connected to the end of the rotating rod 6 away from the fixed plate 5. By setting the handle 16, the rotating rod 6 can be easily rotated by simply squeezing the handle 16 with your hand without the need for tools. The pressing plate 15 has multiple anti-slip protrusions on one side, and the handle 16 has an anti-slip sleeve on the outside. The anti-slip sleeve is made of rubber and has anti-slip texture on its surface. By setting the anti-slip protrusions, the friction force when the operator pushes the pressing plate 15 can be increased. By setting the anti-slip sleeve and anti-slip texture, the friction force when the operator rotates the handle 16 with their hand can be increased, preventing slippage.

[0032] Reference Figures 1-3 A discharge pipe 18 is fixedly connected through the bottom of the barrel 1. A valve is installed at one end of the discharge pipe 18. Multiple support legs are fixedly connected to the bottom of the barrel 1. The support legs have a certain height. After the mixing is completed, the staff can place a collection device at the bottom of the discharge pipe 18 and open the discharge pipe 18 to collect the material in the barrel 1.

[0033] In this utility model, the working principle of an aqueous solution proportioning device for polyacrylamide emulsion production is as follows: When the operator needs to add acrylamide to the tank 1, they first determine the ratio of acrylamide to water by using the scale markings on the outside of the tank 1. Then, they open the top cover of the water inlet 4 and add the aqueous solution into the water inlet 4, allowing water to enter the tank 1. With one hand, they push the pressing plate 15, causing it to move towards the fixed plate 5. The movement of the pressing plate 15 drives the sliding ring 12 to move, which in turn drives the mounting sleeve 11 to move. The mounting sleeve 11 then compresses the spring 14 until the groove on the inner side of the sliding ring 12 completely separates from the locking block on the outer side of the locking sleeve 13. At this point, with the other hand, they hold the handle 16 and rotate it. The rotation of the handle 16 drives the rotating rod 6 to rotate, which in turn drives the U-shaped plate 7 to rotate, which in turn drives the synchronous rotating rod 6 to rotate. Rotate rod 19 until U-shaped plate 7 rotates to the specified tilt angle. At this time, release pressing plate 15. Spring 14 rebounds without being squeezed by mounting sleeve 11. Spring 14 rebounds and drives mounting sleeve 11 to move towards handle 16. The movement of mounting sleeve 11 drives slip ring 12 to move until the inner groove of slip ring 12 completely locks the outer block of locking sleeve 13. Start motor 8. Motor 8 rotates and drives stirring rod 9 to rotate. At this time, open the top cover of feed hopper 3 and add acrylamide to feed hopper 3. Acrylamide enters barrel 1. The bottom size of feed hopper 3 is smaller than the inner size of U-shaped plate 7, so it can fall into the inner side of U-shaped plate 7. Then, acrylamide slides slowly down along the tilted U-shaped plate 7 to the water in barrel 1 through the specified tilt angle of U-shaped plate 7. Finally, acrylamide is fully mixed with water under the action of stirring rod 9.
