Abstract
Description
Technical Field
[0001] This utility model relates to the field of PPO plastic granule processing, and in particular to a PPO plastic granule drying and dehumidification device. Background Technology
[0002] PPO plastic granules, as a thermoplastic general-purpose engineering plastic, exhibit excellent comprehensive properties in white granular form: high rigidity, high thermal stability (glass transition temperature 211°C, melting point 268°C), high strength, top-notch electrical insulation and water resistance. They are dimensionally stable, flame-retardant, lightweight, and non-toxic, making them suitable for the food and pharmaceutical industries. PPO is easy to blend and modify, compatible with materials such as ABS and HDPE, and widely used in the electronics, automotive, and home appliance industries. During the processing of PPO plastic granules, the use of drying equipment is crucial to ensure optimal material performance.
[0003] However, in the existing technology, PPO plastic granules often accumulate inside the drying equipment, which leads to uneven contact between the plastic granules and hot air, thus affecting the drying efficiency and making the overall drying process less efficient. Utility Model Content
[0004] The purpose of this invention is to provide a PPO plastic granule drying and dehumidification device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PPO plastic granule drying and dehumidification device, comprising a base, a housing on the base, a cover plate on the upper end of the housing, a support block fixedly connected to the upper end of the cover plate, an electric push rod on the left side of the support block, a rack fixedly connected to the left side of the electric push rod, a connecting plate fixedly connected to the upper end of the cover plate near the support block, a guide groove opened inside the connecting plate, a guide block slidably connected inside the guide groove, a gear on one side of the rack, a rotating rod fixedly connected to the lower end of the gear, and a rotating plate fixedly connected to the other end of the rotating rod; The inner wall of the shell is provided with an electric heating plate, the inside of the shell is provided with a placement cylinder, the lower end of the shell is fixedly connected with a discharge pipe, the inside of the discharge pipe is provided with a control valve, and the upper edge of the cover plate is fixedly connected with a feeding pipe.
[0006] Preferably, a pressure plate is fixedly connected to the lower end of the base, a movable plate is fixedly connected to the lower end of the pressure plate, a buffer box is provided inside and outside the movable plate, a support leg is fixedly connected to the lower end of the buffer box, and a base plate is fixedly connected to the lower end of the support leg.
[0007] Preferably, a retaining ring is fixedly connected inside the buffer box, a spring is provided inside the retaining ring, a retaining ring is provided at the upper end of the spring, a short rod is fixedly connected at the upper end of the retaining ring, and a damping rod is provided inside the buffer box near the retaining ring.
[0008] Preferably, the guide block slides within the guide groove via a rack and pinion mechanism and an electric push rod.
[0009] Preferably, the number of buffer boxes is two sets, and they are symmetrically arranged about the center line of the base.
[0010] Preferably, the retaining ring slides inside the retaining ring via a spring.
[0011] Using the above technical solution, by activating the electric push rod, the push rod drives the rack to move linearly. During the movement of the rack, its unique tooth structure causes the gear meshing with it to rotate, which in turn drives the rotating rod and rotating plate to rotate synchronously. This chain reaction allows the stirring rod installed on the rotating plate to fully agitate the plastic granules in the placement cylinder, achieving uniform mixing and turning. While the rack moves, the guide block slides inside the guide groove. Under the action of the guide block and guide groove, the stability of the rack movement can be improved. Through the electric push rod, rack, guide block, gear and other components, the plastic granules can be stirred, effectively avoiding the accumulation phenomenon. At the same time, it can also increase the contact area between the plastic granules and hot air, further improving the overall drying efficiency.
[0012] By adopting the above technical solution, the damping rod is used as a preliminary shock absorption measure, which effectively reduces the vibration frequency of the housing. When vibration occurs, the moving plate moves downward and drives the retaining ring to compress the spring. During this process, the spring absorbs and dissipates the energy generated by the vibration, further improving the overall shock absorption effect. The damping rod, spring, retaining ring, retaining ring, moving plate, pressure plate and other components can buffer the working device, thereby ensuring that it is not damaged by vibration and extending its service life.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0020] Example 1 Please see Figures 1-5 This utility model provides a technical solution: a PPO plastic granule drying and dehumidification device, including a base 1, a housing 2 on the base 1, a cover plate 3 on the upper end of the housing 2, a support block 4 fixedly connected to the upper end of the cover plate 3, an electric push rod 5 on the left side of the support block 4, a rack 6 fixedly connected to the left side of the electric push rod 5, a connecting plate 7 fixedly connected to the upper end of the cover plate 3 near the support block 4, a guide groove 8 is opened inside the connecting plate 7, a guide block 9 is slidably connected inside the guide groove 8, a gear 10 is arranged on one side of the rack 6, a rotating rod 11 is fixedly connected to the lower end of the gear 10, a rotating plate 12 is fixedly connected to the other end of the rotating rod 11, an electric heating plate 15 is arranged on the inner wall of the housing 2, a placement cylinder 14 is arranged inside the housing 2, a discharge pipe 16 is fixedly connected to the lower end of the housing 2, a control valve 17 is arranged inside the discharge pipe 16, a feeding pipe 13 is fixedly connected to the upper edge of the cover plate 3, and the guide block 9 slides in the guide groove 8 through the rack 6 and the electric push rod 5.
[0021] Specifically, the electric push rod 5 is activated, which drives the rack 6 to move linearly. During the movement of the rack 6, its unique tooth structure causes the gear 10 meshing with it to rotate, which in turn drives the rotating rod 11 and the rotating plate 12 to rotate synchronously. This chain reaction allows the stirring rod installed on the rotating plate 12 to fully stir the plastic granules in the placement cylinder 14, achieving uniform mixing and turning. While the rack 6 moves, the guide block 9 slides inside the guide groove 8. Under the action of the guide block 9 and the guide groove 8, the stability of the rack 6 during movement can be improved. Through the components such as the electric push rod 5, rack 6, guide block 9, and gear 10, the plastic granules can be stirred, effectively avoiding the accumulation phenomenon. At the same time, it can also increase the contact area between the plastic granules and the hot air, further improving the overall drying efficiency.
[0022] Example 2 Please see Figures 1-5 This utility model provides a technical solution: a PPO plastic granule drying and dehumidification device, wherein a pressure plate 18 is fixedly connected to the lower end of the base 1, a movable plate 19 is fixedly connected to the lower end of the pressure plate 18, a buffer box 20 is provided inside and outside the movable plate 19, a support leg 25 is fixedly connected to the lower end of the buffer box 20, a base plate 26 is fixedly connected to the lower end of the support leg 25, a retaining ring 23 is fixedly connected inside the buffer box 20, a spring 24 is provided inside the retaining ring 23, a retaining ring 22 is provided at the upper end of the spring 24, a short rod 27 is fixedly connected to the upper end of the retaining ring 22, a damping rod 21 is provided inside the buffer box 20 near the retaining ring 23, there are two sets of buffer boxes 20, and they are symmetrically arranged about the center line of the base 1, and the retaining ring 22 slides inside the retaining ring 23 through the spring 24.
[0023] Specifically, the damping rod 21 serves as a preliminary shock absorption measure, effectively reducing the vibration frequency experienced by the housing 2. When vibration occurs, the moving plate 19 moves downward and drives the retaining ring 22 to compress the spring 24. During this process, the spring 24 absorbs and dissipates the energy generated by the vibration, further improving the overall shock absorption effect. The components such as the damping rod 21, spring 24, retaining ring 22, retaining ring 23, moving plate 19, and pressure plate 18 can buffer the working device, thereby protecting it from vibration damage and extending its service life.
[0024] Working Principle: When using this PPO plastic granule drying and dehumidification equipment, firstly, the plastic granules to be dried need to be fed into the placement cylinder 14 through the feeding pipe 13. After feeding, the electric heating plate 15 is activated, and the electric heating plate 15 immediately generates hot air. This hot air enters the placement cylinder 14 to effectively dry the plastic granules. Next, the electric push rod 5 is activated, which drives the rack 6 to move linearly. During the movement of the rack 6, its unique tooth structure causes the gear 10 meshing with it to rotate, thereby driving the rotating rod 11 and the rotating plate 12 to rotate synchronously. This chain reaction allows the stirring rod installed on the rotating plate 12 to fully stir the plastic granules in the placement cylinder 14, achieving uniform mixing and turning. While the rack 6 moves, the guide block 9 slides inside the guide groove 8. Under the action of the guide block 9 and the guide groove 8, the stability of the rack 6 during movement is improved. Through the electric push rod 5, rack 6, and guide block... Components such as gear 10 can stir the plastic granules, effectively preventing accumulation and increasing the contact area between the plastic granules and hot air, further improving the overall drying efficiency. After drying, the control valve 17 is opened, and the plastic granules are discharged from the discharge pipe 16, completing the entire drying process. During equipment operation, the damping rod 21 serves as a preliminary shock absorption measure, effectively reducing the vibration frequency of the housing 2. When vibration occurs, the moving plate 19 moves downward and drives the retaining ring 22 to compress the spring 24. During this process, the spring 24 absorbs and dissipates the energy generated by the vibration, further improving the overall shock absorption effect. Components such as damping rod 21, spring 24, retaining ring 22, retaining ring 23, moving plate 19, and pressure plate 18 can buffer the working device, thereby protecting it from vibration damage and extending its service life.
[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
