Abstract
Description
Technical Field
[0001] The utility model relates to the field of extruders, in particular to an anti-blocking extruder. Background Technique
[0002] Polyacrylamide is a hard glassy solid at room temperature. The products include glue solution, latex, white powder particles, translucent beads and flakes, etc., and it has good thermal stability. It can be dissolved in water in any proportion, and the aqueous solution is a uniform and transparent liquid. During its production process, it is necessary to extrude and form the polyacrylamide raw material through an extruder for subsequent manufacturing.
[0003] Currently, when the existing extruder is in use, it is first necessary to preheat the inside of the machine and then add the polyacrylamide raw material. When the amount of raw material input is too much, it is easy to become blocked at the machine feed inlet, and the too high temperature inside the machine is likely to melt the polyacrylamide raw material and adhere to the feed inlet. If not dredged in time, it is easy to cause the raw material to accumulate at the feed inlet, resulting in blockage. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide an anti-blocking extruder to solve the technical problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-blocking extruder, including a heat preservation cylinder, a barrel and a motor. The inside of the heat preservation cylinder is welded and connected with the barrel through a fixing block. One side of the heat preservation cylinder is provided with a motor. The output end of the motor is connected with a first screw rod through a coupling. The first screw rod is connected with the inside of the barrel through a bearing. One side of the first screw rod is meshed and connected with a second screw rod which is connected with the barrel bearing. The top of the barrel is welded and connected with a feed barrel penetrating through the heat preservation cylinder. The top of the feed barrel is provided with a feed inlet. A driving motor is installed on one side of the top of the feed barrel. The output end of the driving motor is connected with a reciprocating screw rod through a coupling. The outside of the reciprocating screw rod is threadedly connected with a dredging frame. A guide plate is welded and connected inside the feed barrel. The reciprocating screw rod is connected with the guide plate through a bearing.
[0006] Preferably, a heater is installed inside the heat preservation cylinder, and a heating box is welded and connected to one side of the top of the heat preservation cylinder.
[0007] Preferably, an air inlet is opened on one side of the heating box, and a filter screen is connected inside the air inlet through a screw.
[0008] Preferably, a blower is installed inside the heating box, and a heating wire is connected to one side of the blower through a power cord.
[0009] Preferably, a pipeline is connected between the heat preservation cylinder and the heating box, and an air outlet is provided at the bottom of the heat preservation cylinder.
[0010] Preferably, one end of the barrel is connected with a mold through a flange, and a discharge port is provided inside the barrel and the mold.
[0011] In summary, the utility model mainly has the following beneficial effects:
[0012] 1. When the existing anti-blocking extruder feeds polyacrylamide raw materials, due to excessive feeding amount and too high temperature inside the machine, the raw materials are blocked at the feed inlet, and the situation of premature melting and adhesion occurs. Through the first screw, the second screw, the feed cylinder, the feed inlet, the drive motor, the reciprocating lead screw, the dredging frame and the guide plate provided by the utility model, the polyacrylamide raw materials are put into the inside of the feed cylinder through the feed inlet, and at the same time, the drive motor is started, so that the output end of the drive motor drives the reciprocating lead screw to rotate, and the dredging frame threadedly connected to the outside of the reciprocating lead screw can move up and down, so as to achieve the purpose of dredging the blocked polyacrylamide raw materials and prevent the barrel from being blocked during feeding;
[0013] 2. The temperature control of the existing anti-blocking extruder is relatively low. Generally, it is heated by the installed heater, and its heating speed is slow and the heating is uneven. Through the heater, the heating box, the air inlet, the filter screen, the heating wire, the fan, the pipeline, the air outlet, the mold and the discharge port provided by the utility model, the heater is turned on to preheat the inside of the barrel and the heat preservation cylinder. While the polyacrylamide raw materials enter the inside of the barrel for stirring and melting, the fan is turned on, and the heating wire can heat the air at the air inlet, and the hot air enters the inside of the heat preservation cylinder through the pipeline, so that the temperature rises, so as to achieve the purpose of facilitating the melting of the polyacrylamide raw materials.
