Description

Technical Field

[0001] This utility model belongs to the field of polyacrylamide particle production technology, and in particular relates to a grading and screening device for anionic polyacrylamide particles. Background Technology

[0002] Polyacrylamide granules are a widely used polymer material in water treatment, oil extraction, and other fields, often used as flocculants and oil displacement agents. Among them, anionic polyacrylamide granules, due to the introduction of anionic groups such as carboxyl groups on the molecular chain, have a molecular weight, charge density, and particle size that are closely related. The flocculation efficiency and dissolution rate of products with different particle sizes vary significantly, requiring grading according to particle size to adapt to different application scenarios. Traditional screening equipment is prone to agglomeration and screen blockage due to particle stickiness, resulting in low grading accuracy and poor efficiency, which cannot meet the fine processing requirements of anionic polyacrylamide granules. To address this, a grading and screening device for anionic polyacrylamide granules has been developed. Through targeted optimization of the screening structure and temperature control and anti-sticking design, efficient and accurate grading is achieved, ensuring product performance stability.

[0003] However, existing grading and screening devices are not easy to adjust in terms of vibration intensity during use. When faced with particles with high moisture content and viscosity, the lower intensity is insufficient to disperse the particles, causing them to clump together and making it difficult for them to pass through the screen plate. On the other hand, when faced with particles with low moisture content and viscosity, the higher intensity causes some particles that have not yet fallen off the screen plate to be discharged directly from the outlet, thereby reducing the screening quality of the device. Utility Model Content

[0004] The purpose of this invention is to provide a grading and screening device for anionic polyacrylamide particles. By setting up a vibration adjustment part, the invention solves the problem that existing grading and screening devices are not easy to adjust the vibration intensity during use. When dealing with particles with high moisture and viscosity, the low intensity is not enough to disperse the particles, resulting in particle agglomeration and difficulty in passing through the screen plate. When dealing with particles with low moisture and viscosity, the high intensity will cause some particles that have not yet fallen off the screen plate to be discharged directly from the outlet, thereby reducing the screening quality of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a grading and screening device for anionic polyacrylamide particles, comprising a support frame 1 and a support frame 2 fixedly connected to the top of the support frame 1, and a support frame 3 fixedly connected to the top of the support frame 1. It also includes: an adjustment part installed inside the support frame 2; a vibration part disposed inside the support frame 3; the adjustment part includes a sliding component disposed inside the support frame 3; and a limiting component located inside the support frame 2. The sliding component includes a window 1 opened on the support frame 3, and a window 2 opened on the support frame 2. A rotating disk is rotatably connected to the inner wall of the support frame 2, and a slider 1 is slidably connected to the inner wall of the rotating disk. The rotating disk is a circular block, providing the structural basis for adjusting the vibration intensity. The adjustment function is achieved through the cooperation of the rotating disk and the slider 1.

[0006] Furthermore, the vibrating part includes a shaking component disposed within the second bracket; and a separation component mounted on the third bracket, the shaking component being used to drive the separation component to shake.

[0007] Furthermore, the limiting component includes several limiting grooves formed on the inner wall of the rotating disk, and two sliding grooves formed on the inner wall of the first slider. Each of the two sliding grooves is provided with an elastic element. The several limiting grooves are arranged in an array, and the two elastic elements are mirror images of each other. Each elastic element includes a second slider that is slidably connected to the inner wall of the sliding groove. Two springs are fixedly connected to the inner wall of the second slider. The side of each spring away from the second slider is fixedly connected to the sliding groove. The two springs are mirror images of each other. The position of the first slider is fixed by the engagement of the elastic element and the limiting groove, ensuring the stability of the vibration intensity after adjustment.

[0008] Furthermore, the shaking assembly includes a motor fixedly connected to the front side of the second support. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through the second support and through a rotating disk. The outer wall of the rotating shaft is rotatably connected to the second support and fixedly connected to the rotating disk. A limit rod is fixedly connected to the rear side of the first slider. A connecting rod is rotatably connected to the outer wall of the limit rod. A transmission component is provided on the second support. The connecting rod is located behind the rotating disk. The transmission component includes two limit rods two fixedly connected to the top of the second support. A fourth support is slidably connected to the outer walls of the two limit rods two. The left side of the connecting rod is hinged to the fourth support. The top of the fourth support is fixedly connected to the fifth support. The two limit rods two are mirror images of each other and are driven by a motor. Through the transmission structure, they drive the separation assembly to shake, providing power for screening.

[0009] Furthermore, the separation component includes a bracket five slidably connected to the inner wall of bracket three. Two discharge ports are fixedly connected to the outer wall of bracket five. Several collection boxes are provided at the bottom of bracket five. A separation component is provided inside bracket five. Three collection boxes are provided. The left collection box is located on the left side of bracket five, and the two collection boxes on the right side are located at the bottom of the two discharge ports respectively. The separation component includes two screen plates fixedly connected to the inner wall of bracket five. The upper screen plate is inclined to the left, and the lower screen plate is inclined to the rear. The discharge port on the rear side is connected to the area between the two screen plates, while the discharge port on the front side is connected to the bottom area of ​​the lower screen plate. Different particles are separated by means of the inclined screen plates, and the graded particles are collected into the corresponding collection boxes through the discharge ports to complete the grading and screening.

[0010] This utility model has the following beneficial effects: 1. By setting an adjustment section, when adjustment is needed, first turn off the vibration section, manually rotate the rotating disk to align the limiting component with the window, press the second slider to compress the spring so that it is disengaged from the limiting groove, slide the first slider to change the distance between the limiting rod and the rotating shaft, and after releasing, the second slider will be inserted into the limiting groove under the action of the spring. This adjusts the vibration intensity. Moving away from the rotating shaft increases the intensity, and vice versa. This allows for adjustment of the vibration intensity, avoiding the situation where it is difficult to disperse clumps of particles with high humidity and viscosity, and preventing particles with low humidity and viscosity from being directly discharged from the device, thereby ensuring the screening quality of the device. 2. By setting up a vibrating section, when the vibrating section is running, the motor drives the rotating shaft and rotating disk to rotate, causing the limiting rod to drive the connecting rod, allowing the bracket four to slide back and forth along the limiting rod, thereby causing the bracket five to shake. Particles are poured in from the right side and classified by the upper and lower screen plates. Particles of different sizes fall into the collection box from the corresponding discharge ports. This can drive the screen plates to vibrate, causing them to separate the particles on the screen plates. As a result, larger particles are discharged from the discharge ports set on the screen plates, while smaller particles fall below the screen plates.

Three collection boxes 323 are provided: the left collection box 323 is located on the left side of the support frame 321, and the two collection boxes 323 on the right side are located at the bottom of the two discharge ports 322.

By setting the vibrating part 3, the screen plate 324 can be driven to vibrate, so that the particles on the screen plate 324 are separated through the screen plate 324. Thus, larger particles are discharged from the discharge port 322 on the screen plate 324, while smaller particles fall below the screen plate 324.

[0019] It should be noted that the control of motor 311 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be set using existing technologies, such as PLC.

[0020] A specific application of this embodiment is as follows: During use, the motor 311 can be started, causing its output shaft to drive the rotating disk 213 to rotate via the rotating shaft 312. This, in turn, causes the limiting rod 313 to rotate around the rotating shaft 312. At this time, the connecting rod 314 will move along with the limiting rod 313, causing the bracket 316 to slide back and forth on the two limiting rods 315. The bracket 316 will also cause the bracket 321 to sway on the bracket 303. At this time, particles can be poured in from the right side of the bracket 321, while the swaying bracket... Under the action of the support frame 321, medium and small particles will be screened to the bottom of the upper screen plate 324 by the upper screen plate. Particles falling below the upper screen plate 324 will be screened to the bottom of the support frame 321 by the lower screen plate 324. At this time, large particles will fall from the left side of the support frame 321 into the left collection box 323, medium particles will fall from the rear discharge port 322 into the rear collection box 323, and small particles will fall from the front discharge port 322 into the front collection box 323. Inside the header 323, when it is necessary to adjust the intensity of vibration, the vibrating part 3 can be turned off, and a hand can be inserted into window 1 211. Then, the rotating disk 213 can be manually rotated through window 212, and the limiting component 22 can be moved to a position flush with window 212. At this time, the two sliders 223 can be pressed, causing them to slide in the two grooves 222 respectively. At this time, several springs 224 will be compressed and generate elastic force. During the sliding of sliders 223, they will move away from the limiting grooves 221. At this time, the sliders can be slid. When the first limit rod 313 slides upward or downward, the distance between the first limit rod 313 and the rotating shaft 312 will change. After sliding to the corresponding position, the two sliders 223 can be released. At this time, under the action of the spring force 224, the sliders 223 will be locked into the limit groove 221, thereby completing the adjustment. When the first limit rod 313 moves away from the side of the rotating shaft 312, the swing range of the connecting rod 314 when the rotating vibration part 3 starts will increase, thereby increasing the vibration intensity. Conversely, it will decrease the vibration intensity.
