Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyacrylamide production technology, specifically to a polyacrylamide granulation and molding equipment. Background Technology
[0002] Polyacrylamide granules have a wide range of applications. For example, in water treatment, polyacrylamide granules can be used for sludge dewatering, treatment of domestic sewage and organic wastewater, and can effectively carry out coagulation and sedimentation. In addition, they can also be used as a water-reducing agent and oil displacement agent in the field of chemical mining. In the textile industry, they can be used as a sizing agent to stabilize the performance of the sizing liquid and make the fabric surface smoother.
[0003] However, during the production and granulation process of polyacrylamide granules, the equipment needs to be granulated after extrusion molding. When using the granulator, clogging of the template is a common problem, which may be due to the presence of impurities with large particle sizes in the material, thus affecting the normal output. During the granulation process, the blades will affect the smoothness and granulation effect after prolonged use, but they cannot be removed for sharpening or replacement frequently. Therefore, the maintenance of the granulation blades during use is not easy. Utility Model Content
[0004] The purpose of this invention is to provide a polyacrylamide granulation and molding equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyacrylamide granulation and molding equipment, comprising a main body, a hot melter at the top of the main body, a chain mechanism on one side of the main body, a hot melt chamber at the top of the hot melter, the hot melt chamber being cylindrical, the upper side of the chain mechanism being coaxial with the hot melt chamber, a granulation chamber body on the side of the hot melt chamber away from the chain mechanism, a grinding groove embedded in the top of the granulation chamber body, protruding locking blocks on both sides of the grinding groove, a hydraulic cylinder on the upper side of the interior of the granulation chamber body, a granulation storage chamber on the lower side of the interior of the granulation chamber body, a first pressure plate at the lower end of the hydraulic cylinder, and a second pressure plate inserted into the lower outer wall of the movable end of the hydraulic cylinder.

[0008] Preferably, the inner wall of the hot melt chamber is provided with a heat-conducting layer, the heat-conducting layer is electrically connected to the hot melter, and an extrusion hole is provided at one end of the hot melt chamber near the main body of the granulation chamber.
[0009] Preferably, a second servo motor is provided on the lower side of the granulation chamber body at the top of the hot melt chamber, and a pelletizing blade is provided at the output end of the second servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This polyacrylamide granulation molding equipment, by setting a first pressure plate, a second pressure plate, and a limiting block, aims to prevent template blockage when the equipment is used immediately after molding. This necessitates regular cleaning of the discharge hole. During normal pressing, the limiting block inserts into the first pressure plate and rotates 90° to lock into the limiting slot, ensuring the bottom end of the insert rod is flush with the bottom end of the first pressure plate. When unblocking the template, the limiting block penetrates the entire limiting slot and rotates 90°, allowing each insert rod to be inserted into the corresponding discharge hole, thus unblocking the discharge hole and achieving the equipment's automatic unblocking and blockage prevention function.
[0014] 2. This polyacrylamide granulation molding equipment is equipped with a grinding groove, a protruding locking block, and a second servo motor. When the second servo motor drives the pelletizing blade to rotate, the pelletizing blade cuts the extruded polyacrylamide into pellets along the extrusion hole. After continuing to rotate, it will pass through the grinding groove, realizing the function of automatically maintaining the pelletizing blade. Furthermore, the grinding groove assembled by the protruding locking block is easier to assemble and replace. Attached Figure Description
