Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to an acrylamide suspension pretreatment device. Background Technology

[0002] The polymerization of monomer aqueous solutions suspended in an organic solvent with small droplets is called suspension polymerization, also known as bead polymerization. Suspension polymers mainly consist of monomers, initiators, organic solutions, and suspending agents. The initiator is dissolved in the monomer aqueous solution. The dispersant, also called a suspending agent, functions to disperse the monomer aqueous solution into small droplets under stirring and suspend them in the organic solvent to prevent the polymer particles from adhering to each other during polymerization.

[0003] Because mixing requires high-speed flow of wastewater, while sedimentation requires the wastewater to remain still, the two steps need to be operated separately, making it difficult to operate them continuously and efficiently. This results in the relatively low practicality of conventional acrylamide suspension pretreatment devices.

[0004] To address these issues, we propose a pretreatment device for acrylamide suspension. Utility Model Content

[0005] The purpose of this invention is to address the problem of low practicality of conventional acrylamide suspension pretreatment devices, and to propose an acrylamide suspension pretreatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pretreatment device for acrylamide suspension includes a sedimentation tank. A water valve is installed at the bottom of the sedimentation tank, and a stirring tank is fixedly connected to the top of the sedimentation tank. A bearing frame is fixedly connected to the top of the stirring tank, and a stirring tube is rotatably installed inside the bearing frame. A drive motor is also fixedly connected to the bearing frame, and the drive motor meshes with the stirring tube. Acrylamide suspension is poured into the stirring tube, and wastewater is simultaneously discharged into the stirring tube. During this process, the drive motor drives the stirring tube to rotate, mixing the wastewater discharged into the stirring tank with the acrylamide suspension. The rotation of the stirring tube further agitates the mixture, making it more uniform. The mixture is then discharged into the sedimentation tank through the stirring tank for sedimentation. When the sludge buildup at the bottom of the sedimentation tank becomes too thick, the water valve is opened to discharge wastewater, thus facilitating mixing and sedimentation.

[0008] Preferably, a feeding hopper is fixedly connected to the drive motor, the lower part of which is located inside the stirring tube and does not contact the stirring tube. Acrylamide suspension is poured into the feeding hopper and guided into the stirring tube through the feeding hopper, facilitating the addition of acrylamide suspension into the stirring tube.

[0009] Preferably, the mixing tank includes a tank body and a conical trough, with the tank body and the conical trough fixedly connected. After the acrylamide suspension and wastewater enter the conical trough, they are stirred by the rotating stirring pipe before entering the tank body. The mixture is then slowly discharged into the sedimentation tank through the tank body, where it is decelerated by the upper space of the sedimentation tank, thus minimizing its impact on sedimentation.

[0010] Preferably, the bearing bracket includes a fixing rod and a bearing, with the fixing rod fixedly connected to the outer periphery of the bearing. The bearing guides the rotation of the stirring tube, facilitating the mixing of the acrylamide suspension and wastewater within the conical tank.

[0011] Preferably, the stirring tube includes a rotating tube, a first gear, and a brush. The lower part of the rotating tube has a drain outlet. The first gear is fixedly installed on the upper part of the rotating tube, and the brush is uniformly fixedly connected to the lower outer end of the rotating tube. When the drive motor rotates the first gear, the rotating tube rotates, which in turn rotates the brush, causing the wastewater and acrylamide suspension inside the rotating tube to be discharged through the drain outlet. The mixture is then stirred by the brush, facilitating mixing.

[0012] Preferably, the drive unit includes a fixed frame, a motor, and a second gear. The motor is fixedly connected to the inner end of the fixed frame, and the second gear is fixedly connected to the lower part of the motor rotor. The motor drives the second gear to rotate, which in turn drives the first gear to rotate, facilitating the drive unit to rotate the stirring tube.

[0013] Preferably, the drive unit further includes a reinforcing block, which is fixedly connected to the lower end of the fixing frame. The reinforcing block increases the stability between the fixing frame and the fixing rod.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Pour the acrylamide suspension into the mixing tube, and at the same time discharge the wastewater into the mixing tube. During the process, use the drive motor to rotate the mixing tube, so that the wastewater discharged into the mixing tank through the mixing tube mixes with the acrylamide suspension. Use the rotation of the mixing tube to stir, so that the mixture is more uniform. Then discharge it into the sedimentation tank through the mixing tank for sedimentation. When the sludge at the bottom of the sedimentation tank is too thick, open the water valve to discharge the sewage, so as to facilitate stirring, mixing and sedimentation.

[0016] 2. After the acrylamide suspension and wastewater enter the conical tank, they are stirred by the rotation of the stirring pipe and then slowly discharged into the sedimentation tank through the tank body. The sedimentation tank is slowed down by the upper space to reduce the impact on sedimentation.

[0017] 3. When the drive motor drives the first gear to rotate, the first gear drives the rotating pipe to rotate, which in turn drives the brush to rotate, so that the sewage and acrylamide suspension in the rotating pipe are discharged through the drain outlet and then stirred by the brush, which facilitates mixing.
