Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an apparatus for drying polypropylene. Background Technology

[0002] In actual production processes, polypropylene must undergo drying due to specific technological requirements and product quality assurance considerations. This drying process effectively removes excess moisture and other volatile substances from the polypropylene material that may affect its performance, thereby ensuring that the polypropylene product possesses excellent physicochemical properties and stable performance in subsequent processing, molding, and final application stages.

[0003] Existing polypropylene drying devices lack basic filtration functions in their input hoppers. Furthermore, during the feeding of bagged polypropylene, no dedicated platform is provided, requiring manual lifting of the bags to feed them into the input hopper of the drying device. Therefore, it is necessary to design a device for drying polypropylene. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device for drying polypropylene.

[0005] The objective of this utility model can be achieved through the following technical solution: A device for drying polypropylene includes a frame, on which a drying tank is fixed. The bottom of the drying tank has an outlet and an inlet. The inlet is characterized in that the lower parts of both sides of a U-shaped auxiliary component are rotatably connected to the inlet via a connecting shaft. The upper part of the middle of the U-shaped auxiliary component is rotatably connected to one end of a placement platform via a mounting shaft. The other end of the placement platform can abut against the inlet. The inlet also has a filter screen that cooperates with the U-shaped auxiliary component. An arc-shaped groove plate is fixed to the middle of both sides of the U-shaped auxiliary component. A locking bolt that cooperates with the arc-shaped groove plate is threaded onto the inlet.

[0006] A handle is also installed on the upper part of the middle of the U-shaped auxiliary component.

[0007] The lower part of the middle section of the U-shaped auxiliary component is fixedly connected to one end of the elastic strip, and the other end of the elastic strip is fixedly connected to the input bucket.

[0008] The placement platform has an anti-slip pad embedded in the middle.

[0009] A reinforcing block is also fixedly connected between the input bucket and the frame.

[0010] Compared with existing technologies, this apparatus for drying polypropylene has the following advantages: This invention features a rotatable U-shaped auxiliary component and a placement platform. When bagged polypropylene needs to be fed in, the U-shaped auxiliary component can be unfolded downwards, forming a temporary storage area between the U-shaped auxiliary component and the input hopper. The placement platform can then be unfolded upwards, with its end abutting against the input hopper. As a dedicated platform, the placement platform allows for easy feeding without manual lifting. The filter mesh can filter the polypropylene from the temporary storage area, removing any impurities it may contain. Attached Figure Description

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figures 1-3As shown, the apparatus for drying polypropylene includes a frame 1, on which a drying tank 8 is fixed. The bottom of the drying tank 8 has an outlet 11 and an input hopper 2. In this example, the drying tank 8 is also connected to the existing hot air conveying module 10 and material lifting module 9, which is an existing structure. The input hopper 2 is rotatably connected to the lower parts of both sides of a U-shaped auxiliary component 5 via a connecting shaft 4. The upper part of the middle of the U-shaped auxiliary component 5 is rotatably connected to one end of a placement platform 7 via a mounting shaft 14. The other end of the placement platform 7 can abut against the input hopper 2. The input hopper 2 also has a filter mesh 2a that cooperates with the U-shaped auxiliary component 5. The middle parts of both sides of the U-shaped auxiliary component 5 are also fixed. An arc-shaped groove plate 15 is fixed, and a locking bolt 12 that mates with the arc-shaped groove plate 15 is threaded onto the input hopper 2. The angle of the U-shaped auxiliary component 5 can be flexibly adjusted and fixed through the cooperation between the arc-shaped groove plate 15 and the locking bolt 12, so that the U-shaped auxiliary component 5 is in a retracted or extended state. According to actual needs, the middle part of the U-shaped auxiliary component 5 also has a protrusion that mates with the filter mesh 2a. Thus, when the U-shaped auxiliary component 5 is retracted, the protrusion extends into the filter mesh 2a, preventing polypropylene from being trapped in the filter mesh 2a. Therefore, when retracted, the polypropylene to be dried can be put into the input hopper 2 according to the normal process.

[0014] A handle 6 is also installed on the upper part of the middle of the U-shaped auxiliary component 5.

[0015] The lower part of the U-shaped auxiliary component 5 is fixedly connected to one end of the elastic strip 13, and the other end of the elastic strip 13 is fixedly connected to the input bucket 2. The elastic strip 13 can provide a certain sealing performance between the two, while not affecting the normal movement of the U-shaped auxiliary component 5. This is an existing technology.

[0016] An anti-slip pad 7a is embedded in the middle of the placement platform 7. With this structure, the placement platform 7 is unfolded upward so that its end abuts against the input hopper 2. At this time, a certain friction force can be provided to the bagged polypropylene placed on the placement platform 7 to prevent it from slipping off the placement platform 7. In this embodiment, there are two placement platforms 7. The bagged polypropylene can be put into the temporary storage area from the gap between the two placement platforms 7.

[0017] A reinforcing block 3 is also fixedly connected between the input bucket 2 and the frame 1.

[0018] In this example, both the input hopper 2 and the U-shaped auxiliary component 5 adopt an inclined structure, so that polypropylene can automatically enter the input hopper 2 from the U-shaped auxiliary component 5 and finally enter the drying tank 8.

[0019] This utility model is equipped with a rotatable U-shaped auxiliary component 5 and a placement platform 7. When bagged polypropylene needs to be added, the U-shaped auxiliary component 5 can be unfolded downwards, forming a temporary storage area between the U-shaped auxiliary component 5 and the input hopper 2. The placement platform 7 can be unfolded upwards, with its end abutting against the input hopper 2. The placement platform 7 serves as a dedicated platform, allowing for easy material feeding without manual lifting. The filter mesh 2a can perform preliminary filtration of the polypropylene from the temporary storage area, removing any large particulate impurities that may be present. This allows for convenient material feeding and filtration without occupying the space of the input hopper 2.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
