Abstract
Description
Technical Field
[0001] This utility model relates to a plastic pellet draining and drying device. Background Technology
[0002] In the plastics manufacturing industry, producers typically recycle the scraps generated from the production of plastic products. The recycled plastic scraps are usually melted, then extruded into strips, cooled, granulated, washed, drained, and bagged for sale or directly fed into injection molding machines to produce new products. Currently, the method for draining plastic granules involves blowing them dry during the transport process on a long conveyor belt. The biggest problem with this draining method is that it requires a large area and occupies a significant amount of the company's production space.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned problems and provide a plastic pellet draining and drying device, which has the advantages of small size and high drying efficiency.
[0005] To achieve the above objectives, this utility model provides a plastic granule draining and drying device, which includes a draining box, a vibrating motor, and a blower fan. The draining box is provided with a first grid plate and a second grid plate distributed vertically. Both the first grid plate and the second grid plate are inclined. The end of the first grid plate with a higher horizontal height corresponds to the feed inlet of the draining box, and the end of the first grid plate with a lower horizontal height corresponds to the end of the second grid plate with a higher horizontal height. The end of the second grid plate with a lower horizontal height corresponds to the discharge outlet of the draining box. The blower fan is located on the side of the draining box and blows air into the draining box. The draining box has an air inlet structure on the side where the blower fan is located. The vibrating motor is installed at the bottom of the draining box, and a heating element is provided inside the draining box.
[0006] In one or more embodiments, the draining box is provided with a partition that divides the draining box into left and right draining areas, and the partition also divides the first grid plate and the second grid plate into left and right parts.
[0007] In one or more embodiments, the drain box is provided with an air outlet structure on the remaining side where a blower fan is not installed.
[0008] In one or more embodiments, the tilt angle of the first grid plate is 20°-35°, and the tilt angle of the second grid plate is 25°-40°.
[0009] In one or more embodiments, the bottom of the drain box is provided with a water receiving area, and the water receiving area is provided with a drain hole.
[0010] In one or more embodiments, the drain box is provided with a fan cover around the blower fan.
[0011] In one or more embodiments, the draining box, the first grid plate, and the second grid plate are all made of stainless steel.
[0012] In one or more embodiments, a heating element is provided inside the draining box.
[0013] Compared with the prior art, the advantages of this utility model are as follows: plastic granules are fed into the draining box through the inlet, and the water is drained out during the conveying process through the first and second grid plates. The plastic granules are continuously blown by a blower fan to accelerate the evaporation of water on the surface of the plastic granules. Since the upper and lower layer structure conveying method is adopted, the vertical space is fully utilized. Moreover, the blower fan blows into the inside of the draining box, and the air force is more concentrated, which further accelerates the evaporation of water on the surface of the plastic granules.

[0015] Figure 2 This is a structural schematic diagram of the first grid plate, the second grid plate, and the partition plate of this application. Detailed Implementation
[0016] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0017] Please refer to the appendix. Figure 1-2 This application provides a plastic granule draining and drying device, which includes a draining box 1, a vibration motor, and a blower fan 2. The draining box 1 is provided with a first grid plate 3 and a second grid plate 4 arranged vertically. Both the first grid plate 3 and the second grid plate 4 are inclined. The higher end of the first grid plate 3 corresponds to the inlet 6 of the draining box 1, and the lower end of the first grid plate 3 corresponds to the higher end of the second grid plate 4. The lower end of the second grid plate 4 corresponds to the outlet 7 of the draining box 1. Plastic granules are poured into the draining box from the inlet. Then, the plastic granules are conveyed along the first and second grid plates, during which excess water is drained. The blower fan 2 is located on the side of the draining box 1 and blows air into the draining box. As the plastic granules are conveyed along the first and second grid plates, the blower fan dries the moisture on the surface of the plastic granules. The draining box 1 has an air inlet structure 8 on the side where the blower fan 2 is located. The vibration motor is installed at the bottom of the draining box 1. The vibration motor drives the draining box to vibrate, so that the plastic granules can be slowly conveyed from the first and second grid plates.
[0018] In this embodiment, the draining box 1 is provided with a partition 5, which divides the draining box 1 into two draining areas, left and right. The partition 5 also divides the first grid plate 3 and the second grid plate 4 into two parts, left and right. The plastic particles are transported separately to the two draining areas, and the plastic particles in the two draining areas are blown by a blower fan, which can make the plastic particles transported more evenly and make it easier for the surface moisture to be dried by the blower fan.
[0019] The drain box 1 has an air outlet structure 9 on the other side where the blower fan 2 is not installed. Both the air inlet and outlet structures are composed of multiple ventilation holes.
[0020] The tilt angle of the first grid plate 3 is 20°-35°, and the tilt angle of the second grid plate 4 is 25°-40°. The tilt angle of the first grid plate is preferably 25° and the tilt angle of the second grid plate is preferably 30°. The tilt angle of the first grid plate is slightly smaller than that of the second grid plate, which allows the plastic granules on the first grid plate to be conveyed more slowly, which is conducive to the drainage of water. The tilt angle of the second grid plate is slightly larger, so that the plastic granules that have drained excess water through the first grid plate can quickly roll on the second grid plate, thereby ensuring that they are exposed to air from multiple sides and accelerating the evaporation of water.
[0021] The bottom of the drain box 1 is provided with a water receiving area 10, and a drain hole is provided on the water receiving area. The water receiving area collects the drained water and actively discharges it through the drain hole. The drain hole can be connected to a drain hose to guide the drainage.
[0022] The drain box 1 is surrounded by a fan cover 11, which serves a protective function.
[0023] The drain box 1, the first grid plate 3, and the second grid plate 4 are all made of stainless steel. Stainless steel has good waterproof and corrosion-resistant properties, making it suitable as a material for manufacturing the drain box, the first grid plate, and the second grid plate.
[0024] In this embodiment, a heating element is installed inside the draining box 1. The heating element can raise the temperature inside the draining box, which helps the surface moisture of the plastic particles to evaporate faster.
[0025] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
