Description

Technical Field

[0001] This utility model relates to the field of polycarbonate production technology, and in particular to a polycarbonate separation device. Background Technology

[0002] Polycarbonate is widely used in water. In its production, the prepared polycarbonate is granulated. However, after granulation, the particle size is uneven. Therefore, a screening device is usually used for screening. The screen plates of existing screening devices are generally fixed parts that cannot be replaced, resulting in poor applicability of the device.

[0003] Prior art CN221387381U discloses a screening structure for polycarbonate production, including a mobile screening cart, a combined screening screen, and a drive component. The combined screening screen is disposed within the mobile screening cart and includes two sliding members, a rectangular frame, a limiting frame, and a screen frame. The two sliding members are disposed within the mobile screening cart, the rectangular frame is disposed between the two sliding members, the limiting frame is fixedly connected to the lower part of the rectangular frame, and the screen frame is detachably connected to the rectangular frame via multiple latches. The drive component is disposed within the rectangular frame. On one side, when screening polycarbonate particles, the structure is moved to the usage area by a mobile screening vehicle. The corresponding screen frame is selected according to the requirements and fixed by multiple locks. After the polycarbonate particles are poured into the screen frame, the drive unit is activated. The rectangular frame slides back and forth, driving the screen frame to reciprocate. Smaller particles fall through the screen frame to the bottom of the mobile screening vehicle, while larger particles are intercepted above the screen frame. By changing the screen plate, polycarbonate particles with different requirements can be screened to improve the applicability of the structure.

[0004] However, the existing screening structures used in polycarbonate production can only separate larger particles from smaller particles. The smaller particles still contain particles smaller than the required size, resulting in incomplete screening and quality deviations when using polycarbonate. Utility Model Content

[0005] The purpose of this invention is to provide a polycarbonate separation device, which aims to solve the problem that existing screening structures used in polycarbonate production can only separate larger particles from smaller particles, while the smaller particles still contain particles smaller than the required size. This incomplete screening leads to quality deviations when using polycarbonate.

[0006] To achieve the above objectives, this utility model provides a polycarbonate separation device, including a mobile screening vehicle, a combined screening screen, a driving component, and a secondary separation mechanism. The secondary separation mechanism includes a separation frame, a separation screen plate, a discharge plate, a collection box, and two vibrating motors. The combined screening screen is disposed above the mobile screening vehicle, and the driving component is disposed on one side of the combined screening screen. The separation frame is fixedly connected inside the mobile screening vehicle and located below the combined screening screen. The separation screen plate is slidably connected above the separation frame. The discharge plate is fixedly connected to one side of the separation frame. The collection box is slidably connected inside the mobile screening vehicle and located below the discharge plate. The two vibrating motors are fixedly connected to both sides of the separation frame.

[0007] The re-separation mechanism further includes a speed control component, which includes a rotating shaft and a guide plate. The rotating shaft is rotatably connected to the mobile screening vehicle, and the guide plate is fixedly connected to the rotating shaft and rotatably connected to the mobile screening vehicle.

[0008] The speed control assembly further includes a fastening disc and a rotating handle. The fastening disc is threaded to the surface of the rotating shaft, and the rotating handle is fixedly connected to one end of the rotating shaft.

[0009] The re-separation mechanism further includes a replacement plate and a fixing bolt. The replacement plate is slidably connected to the mobile screening vehicle and is located on one side of the separation frame. The fixing bolt is threadedly connected to the mobile screening vehicle and passes through the replacement plate.

[0010] The re-separation mechanism further includes a replacement door and a pull handle. The replacement door is hinged to the mobile screening vehicle and located on one side of the collection box, and is equipped with an observation glass plate. The pull handle is fixedly connected to the surface of the replacement door.

[0011] This utility model discloses a polycarbonate separation device. When using the device, the combined screening screen is adjusted according to the required polycarbonate particle size, and a suitable separation screen plate is selected. The separation screen plate is installed in the separation frame. The drive unit and two vibration motors are activated, and polycarbonate is poured onto the combined screening screen. Larger particles are intercepted, while the remaining polycarbonate falls onto the separation screen plate. Under the action of the two vibration motors, the separation screen plate is in a shaking state, causing smaller particles to pass through the separation screen plate and fall into the bottom of the mobile screening vehicle. Suitable particles on the separation screen plate are then collected in the collection box under gravity along the discharge plate. This avoids the problem of existing screening structures used in polycarbonate production only separating larger and smaller particles, leaving smaller particles still containing particles smaller than the required size, resulting in incomplete screening and quality deviations when using polycarbonate. This device improves accuracy. Attached Figure Description

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] See also Figures 1-4 ,in Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a schematic diagram of the internal structure of the mobile screening vehicle of this utility model; Figure 3 yes Figure 1 A magnified view of a section at point A in the middle; Figure 4 yes Figure 2 A magnified view of a section at point B.

[0020] This utility model provides a polycarbonate separation device, including a mobile screening cart 1, a combined screening screen 2, a driving component 3, and a secondary separation mechanism. The secondary separation mechanism includes a separation frame 4, a separation screen plate 5, a discharge plate 6, a collection box 7, two vibration motors 8, a speed control component 9, a replacement plate 14, fixing bolts 15, a replacement door 16, and a pull handle 18. The speed control component 9 also includes a fastening disc 12 and a rotating handle 13. The aforementioned solution solves the problem that existing screening structures used in polycarbonate production can only separate larger particles from smaller particles, while the smaller particles still contain particles smaller than the required size, resulting in incomplete screening and quality deviations when using polycarbonate.

[0021] In this specific embodiment, the combined screening screen 2 is positioned above the mobile screening vehicle 1, the driving component 3 is positioned on one side of the combined screening screen 2, the separating frame 4 is fixedly connected inside the mobile screening vehicle 1 and located below the combined screening screen 2, the screen separating plate is slidably connected above the separating frame 4, the discharge plate 6 is fixedly connected to one side of the separating frame 4, the collecting box 7 is slidably connected inside the mobile screening vehicle 1 and located below the discharge plate 6, and two vibrating motors 8 are fixedly connected to both sides of the separating frame 4. When using the device, the size of the polycarbonate particles is adjusted according to the desired size. Adjust the combined screening screen 2 and select a suitable separation screen plate 5. Install the separation screen plate 5 in the separation frame 4, start the drive unit 3 and the two vibration motors 8, and pour polycarbonate onto the combined screening screen 2. Larger particles are intercepted, while the remaining polycarbonate falls onto the separation screen plate 5. Under the action of the two vibration motors 8, the separation screen plate 5 is in a shaking state, which causes smaller particles to pass through the separation screen plate 5 and fall into the bottom of the mobile screening vehicle 1. Suitable particles on the separation screen plate 5 will be collected in the collection box 7 along the discharge plate 6 under the action of gravity.

[0022] The speed control component 9 includes a rotating shaft 10 and a guide plate 11. The rotating shaft 10 is rotatably connected to the mobile screening vehicle 1. The guide plate 11 is fixedly connected to the rotating shaft 10 and rotatably connected to the mobile screening vehicle 1. When polycarbonate particles fall from the combined screening screen 2, they first land on the guide plate 11. Depending on the inclination of the guide plate 11, they slide onto the separation screen 5 at different speeds. When controlling the feeding speed of polycarbonate, the rotating shaft 10 can be rotated to drive the guide plate 11 to rotate, thereby changing the inclination of the guide plate 11 and affecting the sliding speed of the polycarbonate particles.

[0023] Secondly, the fastening disc 12 is threaded to the surface of the rotating shaft 10, and the rotating handle 13 is fixedly connected to one end of the rotating shaft 10. When adjusting the guide plate 11, the rotating shaft 10 can be rotated through the rotating handle 13. After the adjustment is completed, the fastening disc 12 is screwed to press against the mobile screening vehicle 1, thereby fixing the rotating shaft 10 and the guide plate 11.

[0024] Meanwhile, the replacement plate 14 is slidably connected to the mobile screening vehicle 1 and is located on one side of the separation frame 4. The fixing bolt 15 is threadedly connected to the mobile screening vehicle 1 and passes through the replacement plate 14. When replacing different separation screen plates 5, the fixing bolt 15 is unscrewed, and then the replacement plate 14 is pulled out. At this time, the separation screen plate 5 can be pulled out for replacement.

[0025] Finally, the replacement door 16 is hinged to the mobile screening vehicle 1 and located on one side of the collection box 7, and is provided with an observation glass plate 17. The pull handle 18 is fixedly connected to the surface of the replacement door 16. When using the device, the collection situation in the collection box 7 can be observed through the observation glass plate 17 for processing. When the collection box 7 is full, the device is closed, and the replacement door 16 is opened by the pull handle 18 to move the collection box 7 out of the mobile screening vehicle 1 for processing.

[0026] When using the device, adjust the combined screening screen 2 according to the required size of the polycarbonate particles, select a suitable separating screen plate 5, install the separating screen plate 5 in the separating frame 4, start the drive unit 3 and the two vibration motors 8, pour the polycarbonate onto the combined screening screen 2. Larger particles are intercepted, while the remaining polycarbonate falls onto the separating screen plate 5. Under the action of the two vibration motors 8, the separating screen plate 5 is in a shaking state, which allows smaller particles to pass through the separating screen plate 5 and fall into the bottom of the mobile screening vehicle 1. Suitable particles on the separating screen plate 5 will be collected in the collection box 7 under the action of gravity along the discharge plate 6. When the polycarbonate particles fall from the combined screening screen 2, they first fall onto the guide plate 11, and slide onto the separating screen plate 5 at different speeds according to the inclination of the guide plate 11. When controlling the feeding speed of the polycarbonate, the rotating shaft 10 can be rotated by the rotating handle 13 to drive the guide plate 11. The device is rotated to change the inclination of the guide plate 11, affecting the sliding speed of the polycarbonate particles. After adjustment, the fastening plate 12 is tightened to press against the mobile screening cart 1, thereby fixing the rotating shaft 10 and the guide plate 11. When changing different separating screen plates 5, the fixing bolts 15 are loosened, and then the replacement plate 14 is pulled out. At this time, the separating screen plate 5 can be pulled out for replacement. When using the device, the collection situation in the collection box 7 can be observed through the observation glass plate 17 for processing. When the collection box 7 is full, the device is closed, and the replacement door 16 is opened by the pull handle 18 to move the collection box 7 out of the mobile screening cart 1 for processing. This avoids the problem that the existing screening structure used for polycarbonate production can only separate larger particles from smaller particles, and the smaller particles still contain particles smaller than the required size. The screening is incomplete, which will lead to quality deviations when using polycarbonate. This improves the accuracy of the device.
