Description

Technical Field

[0001] This utility model relates to the field of material drying technology, specifically to an ABS plastic granule drying device. Background Technology

[0002] ABS plastic granules are granular raw materials of acrylonitrile-butadiene-styrene copolymer. They are commonly used thermoplastic engineering plastics, possessing rigidity, toughness, and processability. They are one of the most widely used "general-purpose engineering plastics" in industry.

[0003] Because ABS plastic granules contain polar components (acrylonitrile), they absorb moisture from the air during storage and transportation. If directly put into processing equipment (such as injection molding machines and extruders), the moisture will quickly vaporize at high temperatures, causing surface defects in the molded products and affecting product quality. Therefore, ABS plastic granules need to be dried before use. Traditional ABS plastic granule drying equipment usually stirs the plastic granules and then introduces hot air to dry the water stains. However, the hot air can only contact the upper layer of granules, resulting in insufficient contact area and affecting drying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an ABS plastic granule drying device. By introducing hot air from below, the ABS plastic granules slide down along a slide plate. During the sliding process, the granules are not only evenly dispersed, increasing the contact area with the hot air, but the hot air also directly penetrates the slide plate through the air holes and diffuses upward from the bottom of the granules, further increasing the contact area between the ABS plastic granules and the hot air. In addition, the slide plate is spirally designed to prolong the falling time of the ABS plastic granules, making the drying more thorough, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ABS plastic granule drying device, comprising:

[0006] Drying jar;

[0007] A fixed cylinder is vertically fixed at the center of the inner cavity of the drying tank. A spiral slide plate is fixed between the inner side wall of the drying tank and the outer side wall of the fixed cylinder. The top and bottom of the drying tank are provided with inlet and outlet ports connected to the slide plate. An air heater is installed at the lower end of the outer side of the drying tank and is connected to the drying tank. Multiple sets of rotating rollers are rotatably connected between the drying tank and the fixed cylinder through bearings. A brush plate is fixed on the outer side of the rotating rollers. The inner cavity of the fixed cylinder is provided with a drive assembly for driving the multiple sets of rotating rollers.

[0008] The top of the drying tank is equipped with an exhaust fan that is connected to the drying tank.

[0009] Preferably, the drive assembly includes a rotating shaft rotatably connected to the inner cavity of the fixed cylinder via a bearing, a drive motor is fixedly mounted on the top of the drying tank, the output shaft of the drive motor is fixedly connected to one end of the rotating shaft, a drive bevel gear is fixedly mounted on the outer side of the rotating shaft, and one end of the rotating roller extends through the inner cavity of the fixed cylinder and is fixedly mounted with a driven bevel gear that meshes with the drive bevel gear.

[0010] Preferably, the top of the slide plate is provided with a raised blocking strip, and the slide plate is provided with air holes.

[0011] Preferably, a flow divider is fixed to the top of the slide plate, and the flow divider is located at the center of the slide plate.

[0012] Preferably, a baffle is fixed between the drying tank and the fixed cylinder, and both ends of the baffle are fixedly connected to the lower part of the slide plate. The baffle is located below the air heater.

[0013] Preferably, the outer side of the rotating shaft is rotatably connected to multiple sets of support plates via bearings, and the support plates are fixed to the inner wall of the fixed cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model involves feeding ABS plastic granules into the feed inlet and allowing them to slide down a spiral slide plate. Then, an air heater draws in and adds outside air, which is then introduced into the drying tank. The hot air diffuses upwards within the drying tank and heats the ABS plastic granules upon contact, causing surface moisture to evaporate. Simultaneously, a rotating roller drives a brush plate to flip the ABS plastic granules on the slide plate. The hot air then diffuses upwards through the air holes between the ABS plastic granules, improving drying efficiency. Subsequently, the humid hot air is extracted by an exhaust fan, reducing the moisture inside the drying tank.

[0016] 2. This utility model, through the setting of the diversion strip, facilitates the diversion of ABS plastic granules on the slide plate, preventing the ABS plastic granules from standing upright on the top of the slide plate and sliding down, thus avoiding the accumulation of ABS plastic granules.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-4 The ABS plastic pellet drying device shown includes:

[0024] Drying container 1;

[0025] A fixed cylinder 2 is vertically fixed at the center of the inner cavity of the drying tank 1. A spiral slide plate 3 is fixed between the inner side wall of the drying tank 1 and the outer side wall of the fixed cylinder 2. The top and bottom of the drying tank 1 are provided with a feed port and a discharge port connected to the slide plate 3. An air heater 4 is installed at the lower end of the outer side of the drying tank 1. The air heater 4 is connected to the drying tank 1. Multiple sets of rotating rollers 5 are rotatably connected between the drying tank 1 and the fixed cylinder 2 through bearings. A brush plate 6 is fixed on the outer side of the rotating rollers 5. The inner cavity of the fixed cylinder 2 is provided with a drive assembly 7 for driving the multiple sets of rotating rollers 5.

[0026] A blower 8 connected to the top of the drying tank 1 is installed;

[0027] The air heater 4 is equipped with an electric heating wire inside, and a blower is installed at the air inlet to blow in external air and drive the air flow.

[0028] ABS plastic granules are fed into the feed port and spiral down the slide plate 3. Then, the air heater 4 draws in outside air and adds it, which is then introduced into the drying tank 1. The hot air diffuses upward in the drying tank 1 and heats the ABS plastic granules when it comes into contact with them, causing the surface water stains to evaporate. At the same time, the rotating roller 5 drives the brush plate 6 to flip the ABS plastic granules on the slide plate 3. Then, the hot air diffuses upward along the air holes between the ABS plastic granules, improving the drying efficiency. Subsequently, the hot air with moisture is extracted by the exhaust fan 8, reducing the moisture inside the drying tank 1.

[0029] Among them, such as Figure 3 As shown:

[0030] The drive assembly 7 includes a rotating shaft 71 rotatably connected to the inner cavity of the fixed cylinder 2 via bearings. A drive motor 72 is fixed to the top of the drying tank 1. The output shaft of the drive motor 72 is fixedly connected to one end of the rotating shaft 71. A drive bevel gear 73 is fixed to the outside of the rotating shaft 71. One end of the rotating roller 5 passes through the inner cavity of the fixed cylinder 2 and is fixed with a driven bevel gear 74 that meshes with the drive bevel gear 73. The drive motor 72 drives the rotating shaft 71 to rotate, and then the rotating shaft 71 drives the drive bevel gear 73. Subsequently, the drive bevel gear 73 drives the rotating roller 5 to rotate through the driven bevel gear 74, so that the brush plate 6 intermittently contacts the ABS plastic granules, which facilitates the flipping of the sliding ABS plastic granules, facilitates contact with hot air, and improves drying efficiency.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown:

[0032] The top of the slide plate 3 is provided with a raised baffle strip 9, and air holes are opened on the slide plate 3. By setting the baffle strip 9, the speed of the ABS plastic granules sliding down is slowed down, so that the ABS plastic granules stay in the drying tank 1 for a longer time, ensuring thorough drying. At the same time, the air holes on the slide plate 3 facilitate the hot air to directly pass through the air holes from below and diffuse upwards, so that it can come into contact with the ABS plastic granules from below, increasing the contact area between the ABS plastic granules and the hot air.

[0033] Preferred, such as Figure 2 and Figure 4 As shown:

[0034] A diversion strip 11 is fixed on the top of the slide plate 3. The diversion strip 11 is located at the center of the slide plate 3. The diversion strip 11 facilitates the diversion of ABS plastic particles on the slide plate 3, preventing the ABS plastic particles from standing on the top of the slide plate 3 and sliding down, and thus preventing the ABS plastic particles from accumulating.

[0035] It is worth noting that, such as Figure 4 As shown:

[0036] A baffle 12 is fixed between the drying tank 1 and the fixed cylinder 2. Both ends of the baffle 12 are fixedly connected to the bottom of the slide plate 3. The baffle 12 is located below the air heater 4. The baffle 12 is designed to block the hot air in the drying tank 1 downwards, preventing the hot air from diffusing downwards and being discharged directly from the outlet, thus avoiding heat waste.

[0037] In a further preferred embodiment, such as Figure 3 As shown:

[0038] Multiple sets of support plates 10 are rotatably connected to the outer side of the rotating shaft 71 via bearings. The support plates 10 are fixed on the inner wall of the fixed cylinder 2. The support plates 10 facilitate the support of the rotating shaft 71, ensuring that the driving bevel gear 73 and the driven bevel gear 74 mesh, and preventing the rotating shaft 71 from shaking and affecting the meshing relationship between the driving bevel gear 73 and the driven bevel gear 74.

[0039] In practical use, ABS plastic granules are slowly injected into the feed port at the top of the drying tank 1. The ABS plastic granules then slide down the slide plate 3. At the same time, the air heater 4 draws in outside air and heats it. The hot air is then introduced into the drying tank 1 and diffuses upwards inside the drying tank 1. It then contacts the ABS plastic granules on the slide plate 3 along the space between the slide plates 3. Simultaneously, the hot air also passes directly through the air holes of the slide plate 3 and contacts the ABS plastic granules above. The hot air heats the ABS plastic granules, causing the water stains on their surface to heat up and vaporize rapidly. The exhaust fan 8 above draws the hot air containing it out of the drying tank 1, ensuring airflow inside the drying tank 1 and expelling moisture. At the same time, the drive motor 72 drives the rotating shaft 71 to rotate. The rotating shaft 71 drives the drive bevel gear 73 to rotate. Then, the drive bevel gear 73 drives the rotating roller 5 through the driven bevel gear 74. The rotating roller 5 drives the brush plate 6 to flip the ABS plastic granules on the slide plate 3, ensuring that the ABS plastic granules are evenly heated and dried.
