Abstract
Description
Technical Field
[0001] This utility model relates to the field of amino molding compound production technology, and in particular to a cooling and drying device for amino molding compound production. Background Technology
[0002] Amino molding compounds are common thermosetting plastics, with phenolic and urea-formaldehyde resins being the most common varieties. They are typically produced in granular form during processing and are widely used in molding and injection molding. Amino molding compounds possess excellent mechanical strength, heat resistance, and corrosion resistance, and their processing technology is simple, meeting the needs of various high-performance applications. Granulated amino molding compound granules may contain a small amount of moisture, especially when formaldehyde or moisture in the resin is not completely removed. To ensure product quality, the granules usually require drying.
[0003] Most existing amino molding compound granules are dried in an oven. During drying, the amino molding compound granules remain stationary, making it difficult to ensure uniform and complete drying. Furthermore, they need to be allowed to cool naturally after drying before they can be removed, which takes a long time and is not conducive to continuous drying work, thus reducing work efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling and drying device for the production of amino molding compounds.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cooling and drying device for the production of amino molding compounds includes: a drying chamber and a drying cylinder. The two ends of the drying chamber are respectively horizontally connected to a first rotating shaft and a second rotating shaft. The drying cylinder is horizontally welded to one end of the first rotating shaft. The first rotating shaft is welded to the outer periphery inside the drying chamber with a first stirring blade. One end of the second rotating shaft extends into the drying cylinder and is rotatably connected to the drying cylinder. The outer periphery of the second rotating shaft is welded to the outside and the inside of the drying cylinder with a second stirring blade and a third stirring blade, respectively. Both sides of the inside of the drying chamber are provided with annular pipes, and the inner sides of the two annular pipes are respectively inclinedly connected to a first air supply branch pipe and a second air supply branch pipe.
[0007] A drive mechanism is used to drive the first rotating shaft and the second rotating shaft to rotate;
[0008] An air supply mechanism is used to supply air to two annular pipes.
[0009] As a further technical solution of this utility model, the four corners of the bottom of the drying oven are vertically welded with support legs, a controller is fixedly installed on the outer side of the drying oven, and a cover plate is hinged at the center of the top and bottom of the drying oven. An exhaust pipe is vertically connected to one side of the bottom of the drying oven, and a valve is installed on the exhaust pipe.
[0010] As a further technical solution of this utility model, an arc-shaped cover is hinged at the top center of the drying cylinder, and the arc-shaped cover and the drying cylinder are pressed and locked together. Multiple through holes are evenly opened on the surface of the arc-shaped cover, the surface of the drying cylinder and both ends.
[0011] As a further technical solution of this utility model, multiple first stirring blades, second stirring blades and third stirring blades are provided. Multiple first stirring blades are evenly distributed along the circumference and transverse direction on the outer periphery of the first rotating shaft located inside the drying chamber. Multiple second stirring blades and third stirring blades are evenly distributed along the circumference and transverse direction on the outer periphery of the second rotating shaft located outside and inside the drying cylinder.
[0012] As a further technical solution of this utility model, mounting blocks are welded to both ends of the bottom of the drying oven. The two annular pipes pass through the two mounting blocks respectively and are fixedly connected to the mounting blocks. Multiple first and second air supply branch pipes are provided and evenly distributed along the circumference inside the two annular pipes. The first and second air supply branch pipes face opposite directions.
[0013] As a further technical solution of this utility model, the driving mechanism includes a rotary motor. A support base is horizontally welded to the outer side of one end of the drying chamber. The rotary motor is horizontally fixedly installed on the top of the support base. The output end of the rotary motor is fixedly connected to one end of a first rotating shaft. A driving bevel gear is welded on the first rotating shaft. A second driven bevel gear is welded to one end of the second rotating shaft. The driving bevel gear and the second driven bevel gear are symmetrically arranged. The sides of the driving bevel gear and the second driven bevel gear are meshed with the first driven bevel gear. A linkage shaft is horizontally welded to the center of each of the two first driven bevel gears. Support blocks are welded to both ends of the outer side of the drying chamber. The two linkage shafts pass through the two support blocks respectively and are rotatably connected to the support blocks. The two linkage shafts are connected by the same belt.
[0014] The starting rotary motor drives the first rotating shaft to rotate in the forward direction. The first rotating shaft drives multiple first stirring blades and the drying cylinder to rotate in the forward direction. The first rotating shaft drives one of the linkage shafts to rotate through a driving bevel gear and one of the first driven bevel gears. One linkage shaft drives another linkage shaft to rotate through a belt. The other linkage shaft drives the second rotating shaft to rotate in the reverse direction through another first driven bevel gear and a second driven bevel gear. The second rotating shaft drives multiple second and third stirring blades to rotate in the reverse direction. The drying cylinder and the multiple third stirring blades inside the drying cylinder rotate in opposite directions. This allows the amino molding compound inside the drying cylinder to be continuously stirred and turned over, so that each amino molding compound can be fully contacted with the hot air, thus ensuring that the amino molding compound dries more evenly and completely.
[0015] As a further technical solution of this utility model, the air supply mechanism includes a hot air blower and a cold air blower. A mounting base is welded to the upper part of one side of the drying chamber. The hot air blower and the cold air blower are fixedly installed side by side at the bottom of the mounting base. The air outlets of the hot air blower and the cold air blower are vertically connected to air outlet pipes. Valves are installed on both air outlet pipes, and the bottom of the two air outlet pipes are horizontally connected to the same C-shaped pipe. Both ends of the C-shaped pipe extend into the interior of the drying chamber and are respectively connected to two annular pipes.
[0016] During drying, the valve on the hot air blower's outlet pipe is opened, and the hot air blower generates hot air that enters two annular pipes through the outlet pipe and C-shaped pipe. Then, multiple first and second air supply branch pipes generate spiral hot air in opposite directions, blowing it onto the amino molding compound inside the drying cylinder. At the same time, the first and second stirring blades rotating in opposite directions also stir and mix the hot air, allowing the hot air to contact the amino molding compound more evenly and powerfully for drying, resulting in better drying effect and shorter drying time. After drying, the valve on the cold air blower's outlet pipe is opened, and the cold air blower is started. In the same way, the dried amino molding compound is cooled, accelerating its cooling speed and eliminating the need to wait for natural cooling, which facilitates continuous drying work and improves work efficiency.
[0017] The beneficial effects of this invention are as follows: the stirring force in different directions can continuously stir and turn the amino molding compound inside the drying cylinder, and can generate a more uniform and powerful spiral airflow in different directions, so that each amino molding compound can be fully in contact with the hot air, thereby ensuring that the amino molding compound dries more evenly and completely, with better drying effect and shorter drying time; it can also cool the dried amino molding compound, accelerate its cooling speed, eliminate the need to wait for natural cooling, facilitate continuous drying work, and improve work efficiency.
