Description

Technical Field

[0001] This utility model belongs to the field of polyacrylamide drying technology, and in particular relates to a polyacrylamide drying device. Background Technology

[0002] Drying is a key step in the production process of polyacrylamide. Drying can transform the polymerized polyacrylamide from a liquid to a solid state, making it easier to store, transport and use the product. During drying, the material is placed on a tray, and hot air circulates in the drying chamber, making full contact with the material. For example, in some multi-layer tray-type hot air drying chambers, the material is evenly spread on the tray, and hot air enters from the bottom or side vents, passes through the material layer, and takes away the moisture.

[0003] As moisture evaporates, the humidity in the drying chamber gradually increases. The exhaust port in the ventilation system can expel the high-humidity air, while the air inlet will replenish fresh air. The existing integrated open structure cannot adjust the airflow. In order to ensure that the air humidity in the drying chamber is maintained at a suitable level, we propose a polyacrylamide drying device with adjustable airflow to solve the above-mentioned shortcomings. Utility Model Content

The output shaft of the servo motor passes through the support frame and extends to the inner cavity of the support frame, where a shaft is fixedly connected. The surface of the shaft is rotatably connected to the support frame via a bearing. A gear is fixedly connected to the surface of the shaft.

[0010] Preferably, the front of the drying chamber is provided with a door.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses hot air generated by a hot air blower to blow hot air onto the powder material on the placement plate through ventilation holes. The hot air passes through the material layer and carries away the moisture. As the moisture evaporates, the air humidity in the drying chamber will gradually increase. At this time, it is only necessary to exhaust the high humidity air by exhausting it and replenishing fresh air at the same time. When it is necessary to adjust the inlet and outlet flow rate, it is only necessary to adjust it through the adjustment structure in the air duct. By setting the above structure, the air inlet and outlet flow rate can be adjusted to ensure that the air humidity in the drying chamber is maintained at a suitable level.

[0013] 2. This utility model uses a servo motor to drive the shaft to rotate, the shaft to drive the gear to rotate, which in turn drives the toothed ring plate to rotate, and drives the adjusting plate to rotate around the rod body as the center point, so that the fixed plate and the rod body can overlap or be offset, thereby adjusting the duct opening and thus adjusting the air inlet and outlet flow rate;

[0014] 3. This utility model, by setting a through hole, allows the gear to mesh with the toothed ring plate, thereby driving the toothed ring plate to rotate;

[0015] 4. This utility model guides the rotation of the adjustment plate and supports it by setting the outer surface of the sliding block to slide and connect it to the inner surface of the sliding groove. Attached Figure Description

[0023] In the following description, embodiments of the polyacrylamide drying apparatus of the present invention will be described with reference to the accompanying drawings.

[0024] Example:

[0025] Figure 1-4This invention illustrates a polyacrylamide drying device according to an embodiment of the present invention, comprising a drying chamber 1, a door on the front of the drying chamber 1, multiple partitions 2 fixedly connected vertically to the inner cavity of the drying chamber 1, placement plates 3 placed between the partitions 2, multiple convection ventilation holes 4 opened inside the partitions 2, a hot air fan 5 fixedly connected to the bottom of the inner cavity of the drying chamber 1, an airflow cavity formed at the top of the inner cavity of the drying chamber 1 and fixedly connected to an exhaust fan 6, and an air duct 7 connected to the top of the drying chamber 1 at a position corresponding to the exhaust fan 6, the air duct 7 having an adjustment structure inside, the adjustment structure being used to adjust... The airflow adjustment structure includes a support frame 8 fixedly connected to one side of the duct 7. A servo motor 9 is fixedly connected to the top of the support frame 8. The output shaft of the servo motor 9 passes through the support frame 8 and extends into the inner cavity of the support frame 8, where a shaft is fixedly connected. The surface of the shaft is rotatably connected to the support frame 8 via a bearing. A gear 10 is fixedly connected to the surface of the shaft. The surface of the gear 10 penetrates the inner surface of the duct 7. A toothed ring plate 11 meshes with the surface of the gear 10. An adjusting plate 12 is fixedly connected to the top of the toothed ring plate 11. A rod 14 is fixedly connected to the axis of the adjusting plate 12. The inner surface of the duct 7... A fixed plate 13 is fixedly connected to the top. The surface of the rod 14 is rotatably connected to the fixed plate 13 via a bearing seat. A servo motor 9 drives the shaft to rotate, which in turn drives the gear 10 to rotate, thereby driving the toothed ring plate 11 to rotate. This causes the adjusting plate 12 to rotate around the rod 14 as the center point, so that the fixed plate 13 and the rod 14 overlap or stagger, adjusting the duct opening and thus regulating the airflow. A through hole is provided on the surface of the duct 7 at the corresponding position of the gear 10. One side of the gear 10 passes through the through hole and meshes with the toothed ring plate 11. The through hole allows the gear 10 to mesh with the toothed ring plate 11, thereby driving the toothed ring plate 11 to rotate. A sliding block 15 is fixedly connected to the surface of the adjusting plate 12. A sliding groove 16 is opened on the inner surface of the air duct 7. The inner surface of the sliding groove 16 is slidably connected to the outer surface of the sliding block 15. By setting the outer surface of the sliding block 15 to the inner surface of the sliding groove 16, the rotation of the adjusting plate 12 is guided and supported. Both the adjusting plate 12 and the fixed plate 13 are semi-circular designs. The rotation angle of the adjusting plate 12 with the rod 14 as the rotation point is from zero to 180 degrees.

[0026] Working principle: When this utility model is in use, the hot air generated by the hot air blower 5 is blown onto the powder material on the placement plate 3 through the ventilation hole 4. The hot air passes through the material layer and carries away the moisture. As the moisture evaporates, the air humidity in the drying chamber will gradually increase. At this time, the high humidity air is discharged by the exhaust fan 6, and fresh air is replenished at the same time. When it is necessary to adjust the inlet and outlet flow rate, the servo motor 9 drives the shaft to rotate, the shaft drives the gear 10 to rotate, thereby driving the toothed ring plate 11 to rotate, and driving the adjusting plate 12 to rotate around the rod body 14 as the center point, so that the fixed plate 13 and the rod body 14 coincide or stagger, thereby adjusting the pipe opening of the air duct and thus adjusting the inlet and outlet flow rate of the air.
