Description

Technical Field

[0001] This utility model relates to the field of nylon production, and in particular to a vacuum drying device for nylon production. Background Technology

[0002] During the production and processing of nylon, the moisture contained within it can trigger a hydrolysis reaction during the high-temperature molding stage, causing a decrease in the molecular weight of nylon and thus deteriorating the mechanical properties of the product, such as a significant decrease in tensile strength and impact toughness. It can also form defects such as bubbles and silver streaks on the surface of the product. Furthermore, as nylon is increasingly used in high-end fields such as automobiles and electronics, the market has placed more stringent requirements on the quality of nylon. Against this backdrop, vacuum drying equipment for nylon production has emerged, aiming to efficiently remove moisture from nylon and meet the industry's demand for high-quality nylon products.

[0003] Existing vacuum drying equipment for nylon production places the nylon material to be dried in a sealed drying chamber. A vacuum pump extracts air from the chamber to create a negative pressure environment, which lowers the boiling point of water and makes the moisture in the nylon material easier to vaporize. At the same time, a heating system heats the material to provide energy for the moisture vaporization. The vaporized water vapor is then extracted by the vacuum pump, thereby achieving the drying of the nylon material and removing moisture to meet production requirements.

[0004] However, in vacuum drying equipment used for nylon production, when nylon raw materials are put into the drying chamber, there is often severe accumulation, resulting in different degrees of contact between the material and the heat transfer and vacuum environment. This difference ultimately leads to uneven drying effect, affecting the quality stability and performance uniformity of nylon products. Therefore, a vacuum drying device for nylon production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vacuum drying device for nylon production, aiming to improve the problem in the prior art where severe accumulation causes different degrees of contact between the material and the heat transfer and vacuum environment, resulting in uneven drying effect and affecting the quality stability and performance uniformity of nylon products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum drying device for nylon production, comprising a box body, a stirring assembly provided on the side wall of the box body, a feeding assembly provided on the top of the box body, the stirring assembly including a motor fixedly connected to the right side wall of the box body, a rotating rod fixedly connected to the output end of the motor, two electric telescopic rods fixedly connected inside the rotating rod, a slider fixedly connected to the output end of each electric telescopic rod, multiple stirring blades fixedly connected to the surface of each slider, and multiple grooves opened on the side wall of the rotating rod;

[0007] As a further description of the above technical solution: the feeding assembly includes a storage hopper fixedly connected to the top of the box, a fan fixedly connected to the right side wall of the storage hopper, a filter screen fixedly connected to the left side wall of the storage hopper, a dust collection box abutting against the right side wall of the filter screen, and a feeding hopper fixedly connected to the top of the storage hopper.

[0008] As a further description of the above technical solution: a heating mechanism is provided on the right side wall of the box, a vacuum mechanism is provided on the right side wall of the box, and an air outlet mechanism is provided on the left side wall of the box;

[0009] As a further description of the above technical solution: the rotating rod is rotatably connected inside the housing, and the slider is slidably connected inside the rotating rod;

[0010] As a further description of the above technical solution: the stirring blade is slidably connected inside the chute, and the bottom of the box is provided with a discharge port;

[0011] As a further description of the above technical solution: the stirring blade abuts against the inner wall of the box;

[0012] As a further description of the above technical solution: the storage hopper is interconnected with the box body, and the dust collection box is slidably connected to the right side wall of the storage hopper;

[0013] As a further description of the above technical solution: the feed hopper and the storage hopper are interconnected, and an electromagnetic valve is provided between the feed hopper and the storage hopper.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, through the structural design of the stirring assembly, the motor drives the rotating rod to rotate, which in turn drives the stirring blade to rotate. This allows for thorough stirring of the nylon material, effectively preventing nylon from accumulating inside the chamber. This ensures that the material is heated and comes into contact with the vacuum environment more evenly during the drying process, greatly improving the drying effect and ensuring the stability and uniformity of the nylon product quality. The electric telescopic rod can move the slider within the chute, thereby adjusting the position of the stirring blade. By changing the position of the stirring blade, the stirring range can be increased to adapt to the drying needs of nylon materials with different quantities and accumulation states. This solves the problem in the prior art where severe accumulation leads to varying degrees of contact between the material and the heat transfer and vacuum environment, resulting in uneven drying effects and affecting the quality stability and performance uniformity of nylon products.

[0016] 2. In this utility model, through the structural design of the feeding component, the fan can promote the air circulation in the storage hopper, allowing hot air to contact the nylon material more evenly and preheat the nylon. At the same time, the flowing air carries dust and other impurities through the filter screen, which can effectively intercept impurities, purify the air, and prevent impurities from accumulating in the device and affecting the drying effect and equipment operation. The dust collection box can collect the dust and other impurities intercepted by the filter screen, which is convenient for regular cleaning, keeps the inside of the device clean, and enhances the practicality of the vacuum drying device for nylon production.

An air outlet mechanism 6 is installed on the left side wall of the box 1 to discharge the vaporized water vapor from the box 1. The rotating rod 22 is rotatably connected inside the box 1, so that the motor 21 drives the rotating rod 22 to rotate, which in turn drives the stirring blade 25 to rotate. The slider 24 is slidably connected inside the rotating rod 22, and the stirring blade 25 is slidably connected inside the slide groove 26. The slider 24 slides inside the rotating rod 22, which drives the stirring blade 25 to slide inside the slide groove 26, so as to carry out all-round stirring of the nylon inside the box 1. A discharge port is provided at the bottom of the box 1 to facilitate the discharge of dried nylon materials. The stirring blade 25 abuts against the inner wall of the box 1 to carry out deep stirring of the nylon materials.
