Description

Technical Field

[0001] This utility model relates to the field of amino molding compound drying technology, specifically to a high-efficiency drying device for amino molding compounds. Background Technology

[0002] Amino molding compounds are indeed a type of plastic material, produced primarily from urea or urea through polymerization, addition, and condensation reactions. This plastic exists as a colorless or light yellow granular solid, exhibiting excellent physical and chemical properties. Its hardness far exceeds that of ordinary plastics, reaching more than three times, while also possessing good mechanical strength and stability. Furthermore, amino molding compounds also possess excellent fire resistance, moldability, corrosion resistance, and cost-effectiveness.

[0003] In existing amino molding compound granule drying devices, the amino molding compound granules are placed inside the drying kettle, and the hot air can only dry the amino molding compound granules at the top, but cannot effectively blow to the amino molding compound granules at the bottom, resulting in uneven drying; and the discharge speed is slow because the material is discharged by opening the valve on the discharge port.

[0024] This invention provides a high-efficiency drying device for amino molding compounds. Please refer to [link / reference]. Figure 1-4 The apparatus includes a drying kettle 1, on which second vent holes are equally spaced, the diameter of which is smaller than the particle size of the amino molding compound granules to be dried. A feed hopper 7 is connected to the drying kettle 1, and the bottom of the feed hopper 7 is fixedly connected to the drying kettle 1 through a conduit. The bottom of the drying kettle 1 has a discharge port 6. The top of the drying kettle 1 is covered with a lid 2, on which a drying mechanism is installed. A support ring 10 is provided inside the drying kettle 1, and the support ring 10 is slidably connected to the inner wall of the drying kettle 1. The bottom of the support ring 10 is hinged to a support plate 17, on which first vent holes are equally spaced, the diameter of which is smaller than the particle size of the amino molding compound granules to be dried.

[0025] A U-shaped bracket 11 is welded to the bottom of the support ring 10, and an electric push rod 13 is hinged between the support plate 17 and the U-shaped bracket 11. Specifically, a first hinge block is welded to the bottom of the support plate 17, and a second hinge block is welded to the U-shaped bracket 11. Both ends of the electric push rod 13 are hinged to the first hinge block and the second hinge block respectively through pins. When the electric push rod 13 retracts, it can drive the support plate 17 to rotate, so that the amino molding compound granules fall through the gap between the support ring 10 and the support plate 17 and are discharged through the discharge port 6. A vibrator 12 is fixedly connected to the bottom of the U-shaped bracket 11.

[0026] The bottom of the vibrator 12 is fixedly connected to a support beam, and the two ends of the support beam are welded to the inner wall of the drying kettle 1. When the vibrator 12 works, the U-shaped support 11 vibrates, which in turn drives the support ring 10 and the support plate 17 to vibrate, thereby causing the material to vibrate and playing a turning role.

[0027] The drying mechanism includes a blower 5 and a heating device 4 fixedly installed on the lid 2. The heating device 4 can be an air preheater, an existing heating box, or any heating box with heating wires inside. The output end of the blower 5 is connected to the air inlet of the heating device 4 through a conduit. The air outlet of the heating device 4 is connected to the air inlet 81 of the outer annular pipe 8 through a guide pipe 3. A support connecting seat 14 is welded on the outer annular pipe 8. An L-shaped support rod 9 is inserted into the inner wall of the support connecting seat 14. The L-shaped support rod 9 and the support connecting seat 14 are fixed together by bolts. The L-shaped support rod 9 is welded to the inner wall of the drying kettle 1. The inner wall of the outer annular pipe 8 has a first interface 82. The first interface 82 is fixedly connected to the bridge pipe 16. The end of the bridge pipe 16 is fixedly connected to the second interface 151 of the inner annular pipe 15. Multiple jet nozzles are installed at the bottom of the outer annular pipe 8 and the inner annular pipe 15.

[0028] In practical use: Amino molding compound granules are placed on the support ring 10 and support plate 17 inside the drying kettle 1 through the feeding hopper 7; the vibrator 12 is started to make the U-shaped support 11 vibrate, thereby driving the support ring 10 and support plate 17 to vibrate, thus causing the material to vibrate and play a turning role; the blower 5 blows the air heated by the heating equipment 4 into the outer annular pipe 8 and inner annular pipe 15, and then sprays it onto the amino molding compound granules through the nozzle to achieve the drying of the amino molding compound granules;

[0029] After drying, the electric push rod 13 retracts to drive the support plate 17 to rotate, so that the amino molding compound granules fall through the gap between the support ring 10 and the support plate 17 and are discharged through the discharge port 6.
