Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide application technology, and in particular to a rapid dissolution device for polyacrylamide used on site. Background Technology

[0002] Polyacrylamide is a water-soluble polymer with excellent flocculation properties, which can reduce frictional resistance between liquids. It is widely used in water treatment, oil extraction, papermaking, and many other fields. In practical applications, it is necessary to dissolve solid polyacrylamide particles into a homogeneous solution.

[0003] Chinese patent CN214809906U discloses a rapid dissolution device for polyacrylamide, including a dissolution cylinder and a stirring mechanism disposed inside the dissolution cylinder. The dissolution cylinder has a liquid outlet pipe at the bottom and a top cover at the top, which has a feed inlet and an exhaust port. The stirring mechanism includes a stirring motor mounted on the top cover and a stirring rod connected to the stirring motor and extending into the dissolution cylinder. The stirring rod has an upper stirring blade and a lower stirring blade installed sequentially from top to bottom. An annular vent pipe is disposed at the bottom of the dissolution cylinder, which has two rows of exhaust ports. The vent pipe is connected to an air pump outside the dissolution cylinder through an air supply pipe, which has a one-way valve.

U-shaped support 5, which is fixedly installed on the bottom wall of the dissolving tank 1; Crushing mechanism 6 is installed on the upper side wall of the tank cover 2. Crushing mechanism 6 is used to crush the polyacrylamide added into the dissolving tank 1. The dispersing mechanism 7 is located on the lower side wall of the tank cover 2 and is used to disperse the crushed polyacrylamide into the dissolving tank 1. An ultrasonic generator 8 is mounted on a U-shaped support 5.

[0023] The above-described structure enables efficient dissolution of polyacrylamide particles.

[0024] The crushing mechanism 6 includes a crushing barrel 61, which is fixedly installed at the center of the upper side wall of the tank cover 2 and communicates with the interior of the dissolving tank 1. The upper end of the follower shaft 42 extends into the crushing barrel 61, and a number of crushing blades 62 are evenly arranged on the shaft wall of the follower shaft 42 inside the crushing barrel 61.

[0025] By setting up the above structure, polyacrylamide particles can be crushed before entering the dissolving tank 1, refining larger particles, increasing the specific surface area of ​​the particles, thereby improving the contact efficiency between the particles and the solvent and accelerating the dissolving process.

[0026] The dispensing mechanism 7 includes a shield 71, which is fixedly installed on the lower side wall of the can cover 2. The follower shaft 42 is located inside the shield 71 and has a number of blades 72 evenly arranged on the shaft wall.

[0027] By setting up the above structure, the crushed polyacrylamide particles can be evenly dispersed, and the particles that might otherwise aggregate can be evenly distributed to various areas inside the dissolving tank 1, avoiding the accumulation of particles in certain areas and shortening the dissolving time.

[0028] The ultrasonic generating device 8 includes an ultrasonic generator 81 and multiple ultrasonic transducers 82.

The ultrasonic generator 81 is fixedly installed on the lower inner wall of the U-shaped support 5, and the multiple ultrasonic transducers 82 are arranged around the bottom wall of the dissolving tank 1.

[0029] With the above-mentioned structure, when ultrasound propagates in the solution, it acts on polyacrylamide particles using cavitation and mechanical effects. The cavitation effect generates a large number of tiny bubbles in the liquid, and the impact force generated when the bubbles burst can destroy the surface structure of the polyacrylamide particles. The mechanical effect promotes the flow and mixing of the solution through the vibration of ultrasound, accelerating the dissolution of the particles.

[0030] The melting tank 1 is fitted with an insulation shell 9 on its outer side, and an electric heating wire is wound inside the insulation shell 9. A temperature sensor is installed inside the melting tank 1.

[0031] The above structure enables heating of the inside of the dissolving tank 1, improving dissolving efficiency, and the insulation shell 9 reduces heat loss, improving energy utilization efficiency.

[0032] The crushing barrel 61 is equipped with a feeding hopper 611 at the top, through which polyacrylamide particles are added into the crushing barrel 61.

[0033] The upper side wall of the can lid 2 is provided with a liquid injection port 21. The solution is added into the dissolving tank 1 through the liquid injection port 21. The side wall of the dissolving tank 1 is provided with a drain pipe 11. A valve is installed on the drain pipe 11.

[0035] With the above-described structure, the controller 10 has a pre-set suitable dissolution temperature value. A temperature sensor monitors the temperature of the solution in the dissolution tank 1 in real time and feeds this temperature information back to the controller 10. When the temperature received by the controller 10 is lower than the preset value, the controller 10 issues a command to activate the heating wire, heating the dissolution tank 1 to raise the solution temperature. As heating progresses, the temperature sensor continuously monitors the solution temperature and feeds this information back to the controller 10. When the solution temperature reaches the preset value, the controller 10 issues a command to stop heating, causing the heating wire to stop working. Furthermore, the controller 10 can control the operation of the drive motor 3 and the ultrasonic generator 81, enabling automated operation of the device.

[0036] It should be noted that the controller 10 mentioned above uses an STM32 microcontroller. The input and output pins of the microcontroller are connected to the heating wire, temperature sensor, drive motor 3 and ultrasonic generator 81 as described above, and can be implemented by programming the microcontroller. The circuit and program used are common technologies in the field of microcontrollers. Those skilled in the art can easily derive the specific circuit based on the above control relationship description. Therefore, the specific circuit will not be described in detail in this article.

[0037] The inner walls of the crushing barrel 61 and the shield 71 are covered with an anti-stick coating, and the surfaces of the crushing blade 62 and the blade 72 are also covered with an anti-stick coating. The anti-stick coating is a polytetrafluoroethylene coating, which can prevent polyacrylamide particles from adhering.

[0038] It should be noted that this utility model is a rapid dissolution device for polyacrylamide used on site. In use, the solution is first added into the dissolution tank 1 through the injection port 21. Then, the dissolution program is started by the controller 10. The controller 10 turns on the heating wire, the ultrasonic generator 81 and the drive motor 3. The output shaft of the drive motor 3 drives the stirring shaft 4 and the stirring blade 41 to rotate. The stirring blade 41 stirs the solution. Then, the polyacrylamide particles are added into the crushing barrel 61 through the feeding hopper 611. While the stirring shaft 4 is rotating, it will drive the follower shaft 42 to rotate. The rotation of the follower shaft 42 will drive the crushing blade 62 and the blade 72 to rotate. The rotation of the crushing blade 62 can crush the polyacrylamide particles added into the crushing barrel 61. The crushed polyacrylamide particles enter the dissolution tank 1 and are then dispersed by the rotating blade 72. Under the protection of the shield 71, they are evenly distributed around the stirring shaft 4. Then, under the combined action of stirring, heating and ultrasonic waves, the polyacrylamide particles dissolve rapidly. After dissolution, the valve on the drain pipe 11 is opened, and the dissolved solution is discharged through the drain pipe 1.
