Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide granulation technology, specifically to a polyacrylamide granulation device. Background Technology

[0002] When producing polyacrylamide from acrylamide, some polyacrylamide products require hydrolysis for performance optimization. This requires additional hydrolysis reactors, which puts significant pressure on the actual production equipment, floor space, process flow, and process costs. Due to functional requirements, some polyacrylamides need to be hydrolyzed with alkaline solutions to produce negatively charged chains. These negatively charged chains repel each other, resulting in a more straight conformation for the polyacrylamide, which enhances its thickening ability with water.

[0003] For example, CN217414572U discloses a polyacrylamide granulation device, which includes a reactor for generating polyacrylamide. The reactor is connected to a screw extruder granulator. The screw extruder granulator has a hydrolysate pipe on its barrel, through which hydrolysate is injected into the barrel. A fluidized bed is provided below the screw extruder granulator, and the fluidized bed outputs the produced polyacrylamide granules.

[0004] However, in implementing the relevant technology, the above-mentioned polyacrylamide granulation device has the following problems: it is difficult to clean the inside of the granulator extrusion cylinder and it is difficult to dry the inside of the granulator extrusion cylinder, resulting in residual material in the extrusion cylinder, which can easily cause cross-contamination. Therefore, a polyacrylamide granulation device is proposed. Utility Model Content

[0010] The drying mechanism is located on the rear side of the cabinet.

[0011] Preferably, the drying mechanism includes a nitrogen tank disposed on the rear side of the cabinet and a fixing pipe fixedly connected to the outer wall of the L-shaped tube, the fixing pipe being located in front of the solenoid valve.

[0012] A second solenoid valve is provided on the outer wall of the fixed tube. A hose is fixedly connected to one end of the fixed tube, and one end of the hose is fixedly connected to the output end of the nitrogen tank.

[0013] Preferably, the output end of the granulator extrusion cylinder is fixedly connected to an external threaded extrusion nozzle, and a cap-shaped extrusion screen is provided on the front side of the external threaded extrusion nozzle, and the cap-shaped extrusion screen is threadedly connected to the external threaded extrusion nozzle.

[0014] Preferably, a mounting shell is fixedly installed above the extrusion cylinder of the granulator, and an electric telescopic rod is fixedly installed through one side of the mounting shell, with a mounting plate fixedly connected to the output end of the electric telescopic rod.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] After granulation, the water pump and solenoid valve one are started, and solenoid valve two is closed. The water pump draws water from the water tank and delivers it through an L-shaped pipe to the inside of the hollow sealing rod, then sprays it out from the nozzle to clean the inside of the granulator's extrusion cylinder.
