Description

Technical Field

[0001] The utility model relates to the technical field of nylon particle production, in particular to air-drying equipment for producing enhanced nylon particles. Background Art

[0002] Nylon 66 is polyhexamethylene adipamide. In order to improve the tensile strength, impact strength, modulus, wear resistance and dimensional stability of nylon 66, a reinforcing agent is often added to the polymer matrix of nylon 66. The improved nylon 66 is reinforced nylon 66. Reinforced nylon 66 has excellent wear resistance, heat resistance and electrical properties, high mechanical strength, self-extinguishing ability, good dimensional stability, and is widely used in automotive industrial products, textile products, pump impellers and primary precision engineering components.

[0003] The patent number CN219045884U in the prior art discloses a nylon plastic granule production air drying device, including a tank body, the lower surface of the tank body is respectively fixedly connected with a support frame and a discharge pipe, the upper surface of the tank body is fixedly connected with a feed hopper, the middle part of the inner bottom wall of the tank body is provided with a drive motor, the output shaft of the drive motor is fixedly connected with a cylinder, and the side of the cylinder is provided with a plurality of air holes, and the surface of the cylinder is provided with a spiral blade. The utility model is convenient for the nylon plastic granules entering the tank body from the feed funnel to fall on the spiral blades through the provided cylinder, spiral blades and spiral baffles, and then by providing a hollow tube, a sealed bearing and a vent pipe, it is convenient to connect the vent pipe to an air pump, so that the gas enters the cylinder through the vent pipe and the hollow tube, and goes out through the air holes on the surface of the cylinder, and the plastic granules rolling on the surface of the spiral blades are air dried, thereby increasing the effect of air drying the nylon plastic granules.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) The device of the prior art increases the uniform air-drying effect by rolling the nylon plastic particles on the surface of the spiral fan blades. However, when the number of nylon particles is large, the nylon particles are prone to accumulation, which results in a small contact area with the air, causing uneven heating of the nylon particles, thereby causing uneven internal drying. When the nylon particles fall onto the rotating spiral fan blades, they are quickly transported out of the tank, which easily leads to incomplete air-drying and reduces the drying effect.

[0006] (2) The prior art device discharges materials through a collecting funnel and a Y-shaped discharge pipe. Since most nylon particles have a certain elasticity, the material outlet is easily blocked during discharge, which affects the normal operation of the operation, wastes time, and reduces production efficiency.

[0029] The air drying box 2 is provided with an auxiliary material unloading component 4, which includes a material guide mesh plate 1 41 and a material guide mesh plate 2 42. The material guide mesh plate 1 41 is fixedly connected to the front and rear ends of the inner wall of the air drying box 2. The material guide mesh plate 1 41 is set high in the middle and low on both sides. A material unloading through hole 1 is opened on both sides of the material guide mesh plate 1 41. The material guide mesh plate 2 42 is fixedly connected to the two sides of the inner wall of the air drying box 2. The material guide mesh plate 2 42 is set high in the middle and low in the middle. A material unloading through hole 2 is opened in the middle of the material guide mesh plate 2 42. The material guide mesh plate 1 41 and the material guide mesh plate 2 42 are staggered. When the reinforced nylon particles enter the air drying box 2, they are first dispersed by the material guide mesh plate 41, then contact the material guide mesh plate 42 during the falling process, and slide down to the material guide mesh plate 41 again, and disperse and slide down along the material guide mesh plate 41, so that the reinforced nylon particles pass through the surfaces of multiple staggered material guide mesh plates 41 and 42 when falling, which increases the contact time between the reinforced nylon particles and the hot air flow. Therefore, during the falling process, there is no accumulation between the reinforced nylon particles, and the contact area with the air inside the air drying box 2 is large, so that the reinforced nylon particles are heated evenly.
