[0049] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a PVC granule filtration device.

[0050] A PVC granule filtering device includes a machine body 1 and a receiving hopper 2, and also includes multiple support columns 3, which are disposed on the machine body 1 and fixedly connected to the machine body 1; a discharge port 4, disposed on the machine body 1, for discharging PVC granules; a feed hopper 5, disposed on the machine body 1 and fixedly connected to the machine body 1; two isolation doors 6, which are disposed on the machine body 1 and rotatably connected to the machine body 1; and a filtering mechanism, disposed on the machine body 1, for filtering PVC granules.

[0051] refer to Figure 1 and Figure 2 In a preferred embodiment, the filtration mechanism includes: a sliding part disposed on the body 1 for mounting some components of the filtration mechanism; a driving part disposed on the body 1 and the sliding part for providing power to the filtration mechanism; and a cleaning part disposed on the body 1 for cleaning impurities remaining after filtration.

[0052] refer to Figure 2 and Figure 3 as well as Figure 4 In a preferred embodiment, the sliding part includes: multiple mounting grooves 7, which are disposed on the machine body 1; multiple slide rails 8, which are disposed within the mounting grooves 7 and fixedly connected to the mounting grooves 7; multiple sliders 9, which are disposed on the slide rails 8 and slidably connected to the slide rails 8; a first sieve plate 10, which is disposed on the sliders 9 and fixedly connected to the sliders 9; and a second sieve plate 11, which is disposed on the sliders 9 and fixedly connected to the sliders 9.

[0053] In this configuration, the first screen plate 10 and the second screen plate 11 are used to filter PVC granules. The aperture of the first screen plate 10 is larger than that of the second screen plate 11. The first screen plate 10 and the second screen plate 11 can slide on the slide rail 8 via the slider 9. The first screen plate 10 and the second screen plate 11 are inclined to facilitate the collection of impurities remaining on the first screen plate 10 and the second screen plate 11.

[0054] refer to Figure 4 and Figure 5 In a preferred embodiment, the drive unit includes: a connecting plate 12, disposed on the first sieve plate 10 and the second sieve plate 11, and fixedly connected to the first sieve plate 10; a fixing groove 13, disposed within the machine body 1, for mounting components of the drive unit; a moving plate 14, disposed within the fixing groove 13, and slidably connected to the fixing groove 13; a swinging member 15, disposed within the fixing groove 13, and rotatably connected to the fixing groove 13; a motor 17, disposed within the fixing groove 13, and fixedly connected to the fixing groove 13; and a rotating member 16, disposed at the output end of the motor 17, and fixedly connected to the output end of the motor 17.

[0055] In this configuration, the movable plate 14 is equipped with a rack; the swing member 15 consists of two parts: one part is a toothed structure that meshes with the rack on the movable member and drives the movable member to slide; the second part is a groove that contacts the cylinder on the rotating member 16. When the rotating member 16 rotates, the cylinder drives the swing member 15 to swing. The part connected to the fixed groove 13 is located at the connection point between the two parts of the swing member 15. The rotating member 16 is equipped with a cylinder. When the cylinder rotates with the rotating member 16, it can slide in the groove of the swing member 15, allowing the swing member 15 to swing as the position of the cylinder changes. When the rotating member 16 rotates one revolution, it drives the swing member 15 to swing back and forth once, and at the same time, it drives the movable member to slide back and forth once.

[0056] refer to Figure 1 and Figure 3 In a preferred embodiment, the cleaning unit includes: two sliding grooves 18 disposed on the body 1 for moving the component; two cleaning plates 19 disposed within the sliding grooves 18 and slidably connected to the sliding grooves 18; and a connecting member 20 disposed on the cleaning plate 19 and fixedly connected to the cleaning plate 19.

[0057] In this configuration, the cleaning plate 19 is used to push away impurities remaining on the first sieve plate 10 and the second sieve plate 11; the connector 20 can connect to the cleaning plate 19, and the cleaning plate 19 can be moved by pulling the connector 20.

[0058] This device, by incorporating a filtration mechanism, accelerates the filtration of PVC granules and prevents clogging caused by PVC granule accumulation, thereby further improving work efficiency. The filtration mechanism also allows for the collection of unfilterable impurities through the inclined first and second screen plates 10 and 11 during the filtration process, facilitating cleaning. Simultaneously, the cleaning plate 19 cleans impurities from the first and second screen plates 10 and 11, simplifying the cleaning process.

[0059] Working Principle: When using this device, the motor 17 is started first. The rotation of the motor 17 drives the rotating component 16 to rotate. The cylinder on the rotating component 16 swings within the fixed groove 13. During swinging, the toothed structure on the swing component 15 meshes with the rack on the moving plate 14, allowing the rack to slide within the fixed groove 13. This sliding motion of the moving component drives the connecting plate 12 to move, which in turn drives the first screen plate 10 and the second screen plate 11. These move along the slide rail 8 via the slider 9. As the motor 17 rotates, the first screen plate 10 and the second screen plate 11 reciprocate. The PVC granules entering the device are sieved by the first screen plate 10 and the second screen plate 11. The filter can move quickly and perform filtration. Impurities that cannot be filtered will move towards the isolation door 6 under the influence of gravity. Finally, the filtered PVC granules will be collected in the receiving bucket 2 through the discharge port 4. Most of the impurities remaining on the first screen plate 10 and the second screen plate 11 are concentrated near the isolation door 6 for easy collection. The remaining impurities on the first screen plate 10 and the second screen plate 11 can be collected by pulling the connecting piece 20. The connecting piece 20 will drive the cleaning plate 19 to slide in the sliding groove 18. The movement of the cleaning plate 19 will push the impurities on the first screen plate 10 and the second screen plate 11 to the side of the isolation door 6 for collection.

[0060] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
