Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic particle drying and separation technology, specifically a drying and separation device based on modified polyphenylene sulfide plastic particles. Background Technology
[0002] Polyphenylene sulfide (PPS) plastic granules are granular materials made of polyphenylene sulfide resin. They belong to high-performance thermoplastic engineering plastics. The presence of moisture in the plastic granules can affect subsequent processing. Therefore, a drying and separation device is used to dry and separate the granules before processing.
[0003] A search revealed Chinese Patent Publication No. CN217257552U, which discloses a drying and separating device for plastic granules. The device includes a base plate, a blower fixedly connected to the upper surface of the base plate, a connecting pipe fixedly connected to one end of the blower, a conical shell fixedly connected to the upper surface of the base plate, and the connecting pipe communicating with the conical shell. A rotating rod movably connected to the upper surface of the base plate is located inside the conical shell, and multiple fan blades are fixedly connected to the outer circumference of the rotating rod. Multiple fixing rods are fixedly connected inside the conical shell, and heating wires are mounted on the fixing rods. A vent plate is fixedly connected to the top of the conical shell. This invention not only avoids overheating of the plastic granules, preventing them from sticking together, but also ensures more uniform heating of the plastic granules, improving drying efficiency and enhancing the stability of the device.
[0004] In the aforementioned utility model, when plastic granules are dried, regardless of their size, the small granules may reach the required moisture content in a short time due to their fast drying speed, but the large granules still need a longer drying time. If the drying time is uniformly extended, it will lead to energy waste for the small granules and incomplete drying of the large granules. Therefore, it is necessary to provide a device that can dry plastic granules in layers to improve the drying quality. Utility Model Content

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.
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] Please see Figure 1-4 As shown, this utility model is a drying and separation device based on modified polyphenylene sulfide plastic particles, comprising:
[0029] The base plate 11, mounting platform 111, drying chamber 12 and feed inlet 15 are provided. The mounting platform 111 is fixed on one side of the upper surface of the base plate 11, the drying chamber 12 is fixed in the middle of the mounting platform 111, the feed inlet 15 is opened in the center of the upper surface of the drying chamber 12, the lower end of the outer surface of the drying chamber 12 is connected to the connecting pipe 13, the end of the connecting pipe 13 is fixed to the hot air blower 14, the upper surface of the drying chamber 12 is provided with ventilation holes 16, and two discharge ports 17 are fixed on one side of the outer surface of the drying chamber 12.
[0030] The base plate 11 serves as the supporting foundation for the entire equipment, ensuring stable operation. The drying chamber 12 is the core drying area, containing plastic granules and drying them with hot air circulation. The feed inlet 15 is the entrance for plastic granules, facilitating direct feeding. The hot air blower 14 provides the hot air required for drying and delivers it to the drying chamber 12 through the connecting pipe 13, forming a forced airflow. The connecting pipe 13 connects the hot air blower 14 and the drying chamber 12, guiding the hot air to be evenly distributed in the drying area.
[0031] The separation assembly includes a limiting frame 21, a mounting plate 22, a rotating groove 23, a first drain hole 24, and a rotating plate 25. The limiting frame 21 is fixed to the upper part of the inside of the drying oven 12, the mounting plate 22 is fixed inside the limiting frame 21, the rotating groove 23 is opened inside the mounting plate 22, the first drain hole 24 is opened on the outer surface of the mounting plate 22, and the rotating plate 25 is installed inside the rotating groove 23.
[0032] The limiting frame 21 restricts the movement range of the mounting plate 22 and the rotating plate 25 to ensure the stability of the separation process. The mounting plate 22 carries the particles and participates in the separation process. The outer surface of the mounting plate 22 has a first leakage hole 24 for the initial screening of small particles. The rotating groove 23 provides the mounting space and rotating track for the rotating plate 25 to ensure that the rotating plate 25 rotates smoothly in the mounting plate 22. When the rotating plate 25 rotates, the second leakage hole 26 periodically coincides with or is offset from the first leakage hole 24, thereby controlling whether the particles pass through the leakage hole.
[0033] The outer surface of the rotating plate 25 is provided with a second leakage hole 26, and the first leakage hole 24 corresponds to the second leakage hole 26. A connecting rod 27 is fixed at the center of the upper surface of the rotating plate 25, and the upper end of the connecting rod 27 passes through the feed inlet 15. A side plate 28 is fixed on the outer surface of the connecting rod 27.
[0034] The connecting rod 27 passes through the feed inlet 15 and connects the rotating plate 25 to the external operating device to transmit rotational power. The side plate 28 is fixed on the outer surface of the connecting rod 27 to enhance the stability of the connecting rod 27 and prevent it from shaking during rotation. The rotating plate 25 adjusts the overlap of the leakage holes to separate small particles and large particles. Small particles fall through the leakage holes onto the air-permeable plate 33 to dry, while large particles remain on the mounting plate 22 to dry.
[0035] Working principle:
[0036] During drying, polyphenylene sulfide plastic granules are fed into the drying chamber 12 through the feed inlet 15. Depending on the size of the plastic granules, the operator rotates the connecting rod 27. The rotation of the connecting rod 27 synchronously drives the rotating plate 25 to rotate. When the rotating plate 25 rotates, the second leakage hole 26 rotates, so that the positions of the first leakage hole 24 and the second leakage hole 26 are staggered. Smaller plastic granules fall through the first leakage hole 24 and the second leakage hole 26 and land on the lower vent plate 33. Larger plastic granules remain on the upper surface of the mounting plate 22, thus drying the plastic granules in layers.
[0037] This step, by adjusting the angle of the rotating plate 25 through the rotating connecting rod 27, can adapt to plastic particles with different particle size distributions, achieve efficient separation, and realize the precise drying treatment of polyphenylene sulfide plastic particles, which combines high efficiency, energy saving and product quality stability.
[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0039] The anti-stick component includes a motor 31, a rotating shaft 32, and a vent plate 33. The motor 31 is fixed on the lower surface of the drying chamber 12, the rotating shaft 32 is fixed at the output end of the motor 31, and the rotating shaft 32 rotates through the drying chamber 12. The vent plate 33 is fixed inside the lower end of the drying chamber 12.
[0040] The motor 31 serves as a power source, driving the rotating shaft 32 and the connecting plate 34 to rotate. The rotating shaft 32 transmits the power of the motor 31, causing the connecting plate 34 and the abutment plate 37 to rotate. The vent plate 33 supports small plastic particles and allows hot air to pass through. The connecting plate 34 generates airflow disturbance through rotation, preventing particles from sticking to the inner wall of the drying oven 12 or the vent plate 33 due to movement or mechanical collision.
[0041] Four connecting plates 34 are fixed on the outer surface of the rotating shaft 32, and the connecting plates 34 have mounting grooves 35 inside. A spring 36 is fixed inside the mounting groove 35, and a stop plate 37 is fixed to one end of the spring 36. The stop plate 37 is in contact with the inside of the drying oven 12.
[0042] The mounting slot 35 inside the connecting plate 34 provides mounting space for the spring 36 and the abutment plate 37. The spring 36 provides elastic force to press the abutment plate 37 tightly against the inner wall of the drying oven 12. Under the elastic force of the spring 36, the abutment plate 37 is tightly attached to the inner wall of the drying oven 12 to prevent plastic particles from entering the outer dead corners or sticking.
[0043] Working principle:
[0044] The hot air blower 14 sends hot air into the drying chamber 12 through the connecting pipe 13. The hot air first comes into contact with the vent plate 33. To prevent the small plastic particles below from melting, the motor 31 is started by the external controller. The motor 31 drives the rotating shaft 32 to rotate. The rotating shaft 32 rotates synchronously and drives the connecting plate 34 to rotate. The connecting plate 34 drives the plastic particles to rotate. Under the elastic force of the spring 36 inside the mounting groove 35, the abutment plate 37 is pressed against the inner wall of the drying chamber 12 to prevent the plastic particles from piling up on the outside of the drying chamber 12.
[0045] In this step, the abutment 37 forms a guide surface by closely adhering to the inner wall, preventing plastic particles from being carried by the airflow to the dead corners outside the drying chamber, which would result in uneven drying.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
