Description

Technical Field

[0001] This utility model relates to the field of PVC particle mixing technology, specifically to a PVC particle mixing device with good mixing effect. Background Technology

[0002] PVC particles are plastic granules made from polyvinyl chloride resin as the base material and by adding a variety of additives. They are mainly used for molding plastic products. Before using PVC particles to process plastic products, various PVC particles and other particles with different properties are mixed to enhance the various properties of the plastic products. In the mixing process, vertical spiral agitators are often used to mix PVC particles and other particles with different properties.

[0003] In existing technology, when using a vertical spiral mixer, PVC particles and other particles with specific properties are conveyed into the vertical mixer through a spiral conveyor component. However, the vertical spiral mixer only conveys the PVC particles and other particles to the top of the vertical mixer and allows them to fall under gravity to achieve mixing. The mixing effect is poor. At the same time, during the mixing process, various materials are discharged through the circulating discharge port and circulated into the vertical spiral mixer tank. However, when discharging from the circulating discharge port, only the mixed particles near the circulating discharge port can be discharged. This causes the material at the bottom of the vertical spiral mixer to remain stationary or flow slowly for a long time, resulting in poor mixing effect as well. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a PVC particle mixing device with good mixing effect includes a mixing tank 1. A first fixed cylinder 2 is fixedly installed in the middle of the mixing tank 1. A first screw conveyor assembly 3 is installed inside the first fixed cylinder 2. A motor 4 for driving the first screw conveyor assembly 3 to rotate is fixedly installed at the bottom of the mixing tank 1. The top end of the first screw conveyor assembly 3 is rotatably installed at the top center of the mixing tank 1 through a bearing. Pusher plates 5 are symmetrically fixedly installed on the outer side of the top end of the first screw conveyor assembly 3. The bottom end of the pusher plate 5 is in contact with the mixing material. The bottom inner wall of the mixing tank 1 is provided with a second fixed cylinder 6 symmetrically fixedly installed on the top inner wall of the mixing tank 1. A second screw conveyor assembly 7 is rotatably installed at the top of the mixing tank 1 corresponding to the middle position of the second fixed cylinder 6 via a bearing. The second screw conveyor assembly 7 is located inside the second fixed cylinder 6 and is drively connected to the first screw conveyor assembly 3. A circulating discharge pipe 14 is fixedly installed at the bottom of the mixing tank 1. The circulating discharge pipe 14 is connected to the interior of the mixing tank 1 and slides inside. A baffle 15 is inserted into the mixing tank 1. A feeding hopper 16 is fixedly installed on the outer bottom of the mixing tank 1, corresponding to the position of the circulating material discharge pipe 14. PVC particles and other materials are poured into the feeding hopper 16. The first screw conveyor assembly 3 is driven to rotate by the motor 4. The material inside the feeding hopper 16 is conveyed through the bottom of the mixing tank 1 to the top of the first fixed cylinder 2 and discharged from the top of the first fixed cylinder 2. The material falls into the mixing tank 1 for mixing. During the mixing process, the second screw conveyor assembly 7 is controlled to rotate, and the material inside the mixing tank 1 is conveyed through the second screw conveyor assembly 7. The bottom of the fixed cylinder 6 is conveyed to the top of the second fixed cylinder 6 and discharged, which can further mix the material inside the mixing tank 1 and improve the mixing effect. When the material is discharged from the circulating discharge pipe 14 to the feeding bin 16 by pulling the baffle 15, the rotation of the first screw conveyor assembly 3 will drive the pusher plate 5 to rotate. The pusher plate 5 can push the material at the bottom inner wall of the mixing tank 1, and can evenly discharge the material at the bottom inner wall of the mixing tank 1 from the circulating discharge pipe 14 and fall into the feeding bin 16, realizing the cyclic feeding of the material and improving the mixing effect.

[0021] like Figures 1 to 4 As shown, a fixing frame 8 is fixedly installed at the top of the first spiral conveying assembly 3, and a gear ring 9 is fixedly installed on the outer side of the fixing frame 8. A first driven gear 10 is fixedly installed at the top of the second spiral conveying assembly 7, and the first driven gear 10 is meshed with the gear ring 9.

[0022] When the first spiral conveying assembly 3 is driven to rotate by the motor 4, the gear ring 9 on the fixed frame 8 at the top of the first spiral conveying assembly 3 will be driven to rotate synchronously. The second spiral conveying assembly 7 can be driven to rotate synchronously by the meshing of the first driven gear 10 and the gear ring 9.

[0023] like Figures 1 to 4 As shown, a rotating rod 11 is symmetrically mounted on the top of the mixing tank 1 via a bearing. A stirring blade 12 is fixedly mounted at equal intervals in the middle of the rotating rod 11. A second driven gear 13 is fixedly mounted on the top of the rotating rod 11. The second driven gear 13 meshes with the gear ring 9.

[0024] During the rotation of the first spiral conveyor assembly 3, the meshing of the second driven gear 13 with the gear ring 9 will drive the rotating rod 11 to rotate. The stirring blades 12 installed at equal intervals on the rotating rod 11 can stir the material inside the mixing tank 1, thereby controlling the flow of the material inside the mixing tank 1 and further improving the mixing effect.

[0025] like Figures 1 to 4 As shown, a dust suction pipe 17 is fixedly installed at the top of the mixing tank 1, and the dust suction pipe 17 is connected to the bag filter dust collector.

[0026] The dust generated by the PVC particle material being transported into the mixing tank 1 can be absorbed by the bag filter and the suction pipe 17, thereby improving the quality of the PVC particle mixture.

[0027] This utility model provides a PVC particle mixing device with good mixing effect, and its specific working principle is as follows:

[0028] In operation, PVC particles and other materials are poured into the feeding hopper 16. The motor 4 drives the first screw conveyor assembly 3 to rotate, transporting the material inside the feeding hopper 16 from the bottom of the mixing tank 1 to the top of the first fixed cylinder 2, and then discharging it from the top of the first fixed cylinder 2. The material falls into the mixing tank 1 for mixing. During mixing, the rotation of the first screw conveyor assembly 3 drives the gear ring 9 on the fixed frame 8 at the top of the first screw conveyor assembly 3 to rotate. The meshing of the first driven gear 10 with the gear ring 9 drives the second screw conveyor assembly 7 to rotate, transporting the material inside the mixing tank 1 from the bottom of the second fixed cylinder 6 to the top of the second fixed cylinder 6 and discharging it. This allows for further processing of the material inside the mixing tank 1. The mixing process is improved. At the same time, the meshing of the second driven gear 13 with the gear ring 9 will drive the rotating rod 11 to rotate. The stirring blades 12 installed at equal intervals on the rotating rod 11 can stir the material inside the mixing tank 1, which is used to control the flow of the material inside the mixing tank 1, thereby improving the mixing effect. When the material is discharged from the circulating discharge pipe 14 to the feeding bin 16 by pulling the baffle 15, the rotation of the first screw conveyor assembly 3 will drive the pusher plate 5 to rotate. The pusher plate 5 can push the material at the bottom inner wall of the mixing tank 1, so that the material at the bottom inner wall of the mixing tank 1 can be evenly discharged from the circulating discharge pipe 14 and fall into the feeding bin 16, realizing the cyclic feeding of the material and improving the mixing effect.
