Abstract
Description
Technical Field
[0001] This application relates to the field of resin processing technology, and in particular to a production and processing apparatus for high heat-resistant polyamide-modified polyester resin. Background Technology
[0002] As is well known, polyamide resin is a condensation-type polymer compound with a CONH structure in its molecule. It is usually obtained by condensation polymerization of diacids and diamines. The most prominent advantage of polyamide resin is that its softening point range is particularly narrow. Unlike other thermoplastic resins, it does not have a gradual curing or softening process. Instead, it causes rapid curing when the temperature is slightly below the melting point.
[0003] While existing resin production and processing equipment can perform resin mixing and processing relatively well, the heat recovery and utilization efficiency during resin mixing is not high. Furthermore, the synchronization of resin aeration and mixing within the equipment is poor during heat recovery, making it easy for bubbles to be generated during resin processing, reducing resin production quality. In addition, the preheating effect of the equipment cavity is not good, which can easily lead to increased energy consumption of heat within the equipment after shutdown and restart, thus increasing the operating cost of the equipment. Utility Model Content
[0004] This application provides a production and processing apparatus for high heat-resistant polyamide-modified polyester resin to solve the problems of low efficiency in heat recovery and utilization during resin stirring and poor synchronization of resin aeration and stirring within the apparatus during heat recovery.
[0005] This application provides a production and processing apparatus for high heat-resistant polyamide-modified polyester resin, comprising an apparatus body, an air outlet on the outer wall of the apparatus body, a rotating shaft rotatably connected to the inner wall of the apparatus body, a stirring rod fixedly connected to the outer wall of the rotating shaft, a return pipe detachably connected to the inner wall of the air outlet, a rotary joint fixedly connected to one end of the return pipe and rotatably connected to the inner wall of the rotating shaft, a diversion pipe fixedly connected to the outer wall of the return pipe and fixedly connected to the outer wall of the apparatus body, a heat storage chamber inside the apparatus body, and aeration holes on the surface of the stirring rod.
[0006] Preferably, a servo motor is provided on the outer wall of the main body of the device, and a first gear is fixedly connected to the output end of the servo motor. A second gear, which is fixedly connected to the outer wall of the rotating shaft, meshes with the outer wall of the first gear.
[0007] Preferably, the inner wall of the rotating shaft has a first flow channel, and the inner wall of the stirring rod has a second flow channel.
[0008] Preferably, the stirring rod is interconnected with the rotating shaft through the second flow channel and the first flow channel.
[0009] Preferably, the aeration holes are arranged in a ring on the surface of the stirring rod.
[0010] Preferably, the rotating shaft forms a rotating structure with the device body through a first gear and a second gear.
[0011] Preferably, the outer wall of the diversion pipe is provided with a solenoid valve, and the diversion pipe and the heat storage chamber are interconnected.
[0012] Beneficial effects: While existing resin production and processing equipment can perform resin mixing and processing relatively well, the heat recovery and utilization efficiency during resin mixing is not high. Furthermore, the synchronization of resin aeration and mixing within the equipment is poor during heat recovery, which makes it easy for bubbles to be generated during resin processing, reducing resin production quality. In addition, the preheating effect of the equipment cavity is not good, which can easily lead to increased energy consumption of heat within the equipment after shutdown and restart, thus increasing the operating cost of the equipment.
[0013] When it is necessary to recover and utilize the heat during resin mixing, a return pipe is installed between the outlet and the rotary joint, and a rotary joint is installed between the rotary joint and the rotating shaft. This allows the heat recovered from the outlet to be transported to the rotating shaft through the rotary joint. With the opening of the first and second flow channels, the recovered heat is transported to the aeration holes. The servo motor is then turned on, and the rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the rotating shaft and the stirring rod to rotate synchronously, achieving the effect of aerating and mixing the resin. Through the setting of the diversion pipe, the heat is transported to the heat storage chamber, achieving the effect of preheating the device for use.
