Description

Technical Field

[0001] This utility model relates to the field of PET bottle flake recycling technology, specifically a dryer for recycling and processing recycled PET bottle flakes. Background Technology

[0002] PET plastic bottles are widely used not only for packaging carbonated beverages, drinking water, juice, enzymes, and tea drinks, but are also the most widely used beverage packaging today. They are also widely used in many fields such as food, chemical, and pharmaceutical packaging. However, when these materials are discarded, the problem of how to dispose of them arises. Generally, the recycling and processing method for PET plastic bottles involves using a crusher to crush the bottle body into PET flakes, then using a dryer to remove the moisture from the PET flakes, and finally melting and granulating them into PET raw material granules.

[0003] The published patent document with announcement number CN220417846U discloses a dryer for recycling PET bottle flakes. This published patent document solves the problems of conventional drying methods being unable to uniformly dry a large number of PET bottle flakes and the inability to timely remove large amounts of moisture during the drying process by setting up a base plate, a fixing plate, air pipes, branch pipes, a rotating shaft, and a spherical drying cage. However, the published patent document is an intermittent drying method, which requires drying one batch of PET bottle flakes and then emptying them before the next batch of PET bottle flakes can be dried, resulting in low work efficiency.

Several fixing rings are equidistantly sleeved and fixedly installed on the long rotating shaft. Connecting rods are symmetrically fixedly connected to both sides of the fixing rings. A scraper matching the mesh inclined cylinder is fixedly installed at the end of each connecting rod. A hot air box matching the mesh inclined cylinder is fixedly installed on the rear side of the short support rod.

[0006] By adopting the above technical solution, the drive motor drives the long rotating shaft to rotate. The long rotating shaft, pulley one, belt and pulley two drive the short rotating shaft to rotate. The short rotating shaft, spur gear and ring gear drive the mesh inclined cylinder to rotate in the opposite direction to the long rotating shaft. The rotation of the mesh inclined cylinder can throw the water off the PET bottle flakes and allow the PET bottle flakes to slide along the inside of the mesh inclined cylinder, realizing continuous drying operation and increasing work efficiency. The long rotating shaft, fixed ring and connecting rod drive the scraper to rotate along the inner wall of the mesh inclined cylinder to prevent the PET bottle flakes from accumulating and affecting the drying effect.

[0007] Optionally, the front side of the hot air box is connected to several air outlet pipes, and several electric heating rods are fixedly installed inside the hot air box. A matching box cover is fixedly installed on the rear side of the hot air box, and several air inlets are opened on the box cover. A fan is installed inside the air inlets.

[0008] By adopting the above technical solution, the fan delivers outside air to the inside of the hot air box through the air inlet, the electric heating rod heats the air, and the hot air enters the inside of the mesh inclined cylinder through the air outlet to perform hot air drying operation on the PET bottle flakes inside the mesh inclined cylinder.

[0009] Optionally, the tilt angle of the air outlet pipe is the same as the tilt angle of the mesh inclined cylinder.

[0010] By adopting the above technical solution, hot air can be ensured to move along the inside of the mesh inclined cylinder, thereby increasing the air drying effect.

[0011] Optionally, two limiting rings are fitted onto the mesh inclined cylinder and rotatably connected thereto, and support rods are symmetrically fixedly connected to both sides of the limiting rings.

[0012] By adopting the above technical solution, the stability of the rotation of the mesh inclined cylinder is guaranteed.

[0013] Optionally, a base is provided below the mesh inclined cylinder, the bottom of the support rod is fixedly installed to the top of the base, and the long support rod and the short support rod are respectively fixedly installed on the front and rear sides of the top of the base.

[0014] By adopting the above technical solution, support is provided for the long support rod, the short support rod, and the limiting ring, ensuring the stability of the dryer during operation.

[0015] Optionally, a number of casters are fixedly installed on the bottom of the base.

[0016] By adopting the above technical solution, the dryer can be moved easily.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses a long support rod, a short support rod, a drive motor, a long rotating shaft, a pulley one, a belt, a pulley two, a short rotating shaft, a spur gear, and a ring gear to drive the mesh inclined cylinder to rotate in opposite directions to the long rotating shaft. The rotation of the mesh inclined cylinder can throw out the water on the PET bottle flakes and allow the PET bottle flakes to slide along the inside of the mesh inclined cylinder, realizing continuous drying operation. There is no need to wait for one batch of PET bottle flakes to dry before the next batch is dried, which greatly increases the work efficiency. The long rotating shaft, the fixing ring, and the connecting rod drive the scraper to rotate along the inner wall of the mesh inclined cylinder, preventing the PET bottle flakes from accumulating and affecting the drying effect.

[0019] 2. The technical solution of this application uses a fan to deliver outside air from the air inlet to the inside of the hot air box. The electric heating rod heats the air, and the hot air finally enters the inside of the mesh inclined cylinder through the air outlet to perform hot air drying operation on the PET bottle flakes inside the mesh inclined cylinder. The direction of the hot air flow is opposite to the sliding direction of the PET bottle flakes, which increases the drying effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-2 This utility model provides a dryer for recycling PET bottle flakes, including a mesh inclined cylinder 1. A long support rod 2 and a short support rod 3 are respectively arranged at the front and rear of the mesh inclined cylinder 1. A long rotating shaft 9 passes through the center of the mesh inclined cylinder 1. A drive motor 12 is fixedly installed on the front side of the long support rod 2, and a short rotating shaft 13 is rotatably installed on the rear side of the long support rod 2. The long rotating shaft 9 is rotatably installed between the long support rod 2 and the short support rod 3. A pulley 14 is sleeved and fixedly connected to the front side of the long rotating shaft 9, and a second pulley 15 is sleeved and fixedly connected to the short rotating shaft 13. 5. A spur gear 17 is fixedly installed at the rear end of the short rotating shaft 13. A belt 16 is provided between the pulley 14 and the pulley 15. A ring gear 10 is sleeved and fixedly installed on the front side of the mesh inclined cylinder 1. The ring gear 10 meshes with the spur gear 17. Several fixing rings 18 are equidistantly sleeved and fixedly installed on the long rotating shaft 9. Connecting rods 19 are symmetrically fixedly connected on both sides of the fixing rings 18. A scraper 20 matching the mesh inclined cylinder 1 is fixedly installed at the end of the connecting rod 19. A hot air box 4 matching the mesh inclined cylinder 1 is fixedly installed on the rear side of the short support rod 3.

[0028] In this technical solution, the long rotating shaft 9 is driven by the drive motor 12 to rotate. The long rotating shaft 9 drives the short rotating shaft 13 to rotate through the pulley 14, belt 16 and pulley 15. The short rotating shaft 13 drives the mesh inclined cylinder 1 to rotate in the opposite direction to the long rotating shaft 9 through the spur gear 17 and the ring gear 10. The rotation of the mesh inclined cylinder 1 can throw off the water on the PET bottle flakes and allow the PET bottle flakes to slide along the inside of the mesh inclined cylinder 1, realizing continuous drying operation. There is no need to wait for one batch of PET bottle flakes to dry before the next batch is dried, which greatly increases the work efficiency. The long rotating shaft 9 drives the scraper 20 to rotate along the inner wall of the mesh inclined cylinder 1 through the fixing ring 18 and the connecting rod 19 to prevent the PET bottle flakes from accumulating and affecting the drying effect.

[0029] In some technical solutions, such as Figure 1 , Figure 3 and Figure 4 As shown, the front of the hot air box 4 is connected to several air outlet pipes 23, and several electric heating rods 24 are fixedly installed inside the hot air box 4. A matching box cover 5 is fixedly installed on the rear side of the hot air box 4. Several air inlets 21 are opened on the box cover 5, and a fan 22 is installed inside the air inlets 21.

[0030] In use, the fan 22 delivers outside air through the air inlet 21 to the hot air box 4, the electric heating rod 24 heats the air, and the hot air finally enters the mesh inclined cylinder 1 through the air outlet 23 to perform hot air drying on the PET bottle flakes in the mesh inclined cylinder 1. The hot air flow direction is opposite to the sliding direction of the PET bottle flakes to increase the drying effect.

[0031] In some technical solutions, such as Figure 3 As shown, the tilt angle of the air outlet pipe 23 is the same as the tilt angle of the mesh inclined cylinder 1.

[0032] During use, the air outlet pipe 23, which has the same tilt angle as the mesh inclined cylinder 1, ensures that the hot air can move along the inside of the mesh inclined cylinder 1, thereby increasing the air drying effect.

[0033] In some technical solutions, such as Figure 1 As shown, two limiting rings 6 are fitted onto the mesh inclined cylinder 1 and rotatably connected thereto. Support rods 8 are symmetrically fixedly connected to both sides of the limiting rings 6.

[0034] During use, the limiting ring 6 ensures the stability of the rotation of the mesh inclined cylinder 1.

[0035] In some technical solutions, such as Figure 1 As shown, a base 7 is provided below the mesh inclined cylinder 1, the bottom of the support rod 8 is fixedly installed to the top of the base 7, and the long support rod 2 and the short support rod 3 are fixedly installed on the front and rear sides of the top of the base 7, respectively.

[0036] During use, the base 7 provides support for the long support rod 2, the short support rod 3, and the limiting ring 6, ensuring the stability of the dryer during operation.

[0037] In some technical solutions, such as Figure 1 As shown, several casters 11 are fixedly installed on the bottom of the base 7.

[0038] When in use, the dryer can be easily moved using the casters 11.

[0039] Working principle: During use, the PET bottle flakes to be dried are first placed inside the mesh inclined cylinder 1. The drive motor 12 drives the long rotating shaft 9 to rotate. The long rotating shaft 9 drives the short rotating shaft 13 to rotate through the pulley 14, belt 16 and pulley 15. The short rotating shaft 13 drives the mesh inclined cylinder 1 to rotate in the opposite direction to the long rotating shaft 9 through the spur gear 17 and ring gear 10. The rotation of the mesh inclined cylinder 1 can shake off the water on the PET bottle flakes and allow the PET bottle flakes to slide along the inside of the mesh inclined cylinder 1 to achieve continuous drying operation. The long rotating shaft 9 drives the scraper 20 to rotate along the inner wall of the mesh inclined cylinder 1 through the fixing ring 18 and connecting rod 19 to prevent the PET bottle flakes from accumulating and affecting the drying effect. At the same time, the fan 22 delivers outside air to the hot air box 4 through the air inlet 21. The electric heating rod 24 heats the air. Finally, the hot air enters the inside of the mesh inclined cylinder 1 through the air outlet 23 to perform hot air drying operation on the PET bottle flakes inside the mesh inclined cylinder 1.
