Description

Technical Field

[0001] The utility model relates to the technical field of PE plastic preparation, in particular to a vertical stirring drum-type PE plastic device. Background Art

[0002] Plastic PE has good chemical stability, can withstand the corrosion of most acids and alkalis, is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation properties.

[0003] PE plastics typically require stirring during processing. When using existing drum-type stirring devices for PE plastics, the stirring rod cannot stir the plastic near the inner wall of the drum. This makes it difficult to fully mix the plastics fed into the drum, which affects the physical and chemical properties of the product and results in low-quality plastic products. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a vertical stirring drum type plastic PE device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A vertical stirring drum-type plastic PE device includes a base and an outer cover fixedly arranged on the base. A transmission shaft is inserted into the center of the upper surface of the base. A ring gear and a fixed gear are sleeved on the transmission shaft. The fixed gear is built into the ring gear and maintains meshing transmission with it. The ring gear rotates synchronously with the transmission shaft, and a slewing bearing is sleeved on the outside of the ring gear.

[0007] In a preferred technical solution, a bottom motor is provided inside the base, and a transmission shaft provided at the output end of the bottom motor passes through the base upward and extends into the outer cover.

[0008] In a preferred technical solution, a thrust bearing is provided on the inner side of the fixed gear, and the fixed gear is sleeved on the shaft of the transmission shaft through the thrust bearing and maintains a constant position.

[0009] In a preferred technical solution, the ring gear is sleeved on the transmission shaft and enables the transmission shaft, the ring gear and the slewing bearing to rotate synchronously.

[0010] In a preferred technical solution, the transmission shaft is located at an eccentric position inside the ring gear.

[0011] A stirring drum is installed on the top of the slewing support, a stirring shaft is inserted into the inner center of the stirring drum, and a plurality of stirring rods are arranged on the stirring shaft.

[0012] In a preferred technical solution, a top cover is provided on the top of the stirring drum, a top motor is mounted on the top cover, and a stirring shaft extending into the stirring drum is provided at the output end of the top motor.

[0013] A discharge valve is provided on the side of the stirring drum.

[0014] In a preferred technical solution, a material receiving port is provided on the outer cover and corresponds to the position of the discharge valve port provided on the stirring drum.

[0015] In a preferred technical solution, the outer cover is designed to have a shape that matches the rotation profile of the stirring drum.

[0016] The beneficial effects of the utility model are:

[0017] The stirring drum proposed in this solution solves the problem that the PE plastic in the drum has stirring corners and the plastic cannot be fully stirred and mixed. In the design of this stirring drum, while using the stirring rod to mix the plastic, the stirring drum also rotates centrifugally to drive the plastic that the stirring rod cannot reach as much as possible to move, so that it participates in the stirring environment, thereby improving the uniformity of the PE plastic stirring and ensuring the production quality of subsequent products.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In this embodiment, refer to Figure 1-3A vertical mixing drum-type plastic PE device includes a base 1 and an outer cover 2 fixedly mounted on the base 1. A bottom motor 3 is disposed within the base 1 and is mounted at the center of the base 1. A transmission shaft 15 disposed at the top output end of the bottom motor 3 extends upward through the base 1 and into the outer cover 2.

[0024] The transmission shaft 15 is provided with a ring gear 4 and a fixed gear 7.

[0025] A thrust bearing 6 is provided on the inner side of the fixed gear 7. The thrust bearing 6 can be used to maintain the state of the fixed gear 7. The fixed gear 7 is sleeved on the shaft of the transmission shaft 15 through the thrust bearing 6 and maintains the same position.

[0026] The ring gear 4 rotates synchronously with the transmission shaft 15 , and a slewing bearing 5 is sleeved on the outside of the ring gear 4 . The ring gear 4 is sleeved on the transmission shaft 15 and enables the transmission shaft 15 , the ring gear 4 and the slewing bearing 5 to rotate synchronously.

[0027] It should be made clear that, as Figure 3 As shown, the transmission shaft 15 is located at an eccentric position inside the ring gear 4. In addition, the fixed gear 7 is built into the ring gear 4 and maintains meshing transmission therewith.

[0028] When the bottom motor 3 starts working, the ring gear 4 rotates along with the transmission shaft 15, and the position of the fixed gear 7 remains unchanged. Since the ring gear 4 engages with the fixed gear 7 inside it during the rotation process, the ring gear 4 forms a centrifugal motion trajectory while rotating.

[0029] A stirring drum 8 is installed on the top of the slewing bearing 5. The stirring drum 8 maintains a synchronous motion state with the ring gear 4. Therefore, the stirring drum 8 can maintain centrifugal rotation. Compared with the rotation along the axis of the cylinder, the centrifugal rotation can vibrate the plastic particles inside the stirring drum 8, increase the activity of the plastic particles, increase the probability of collision of the plastic particles during the stirring process, and avoid the situation where some plastic particles cannot be stirred.

[0030] A top cover 9 is provided on the top of the mixing drum 8, on which a top motor 10 is mounted. A stirring shaft 11 extending into the mixing drum 8 is provided at the output end of the top motor 10, and a plurality of stirring rods 12 are provided on the stirring shaft 11. During the rotation of the mixing drum 8 itself, the top motor 10 is synchronously driven to control the rotation of the stirring shaft 11, so that the plastic particles put into the mixing drum 8 can fully contact and mix, thereby improving the uniformity of the PE plastic mixing.

[0031] Finally, as attached Figure 3 As shown, the outer cover 2 is designed to be in a shape adapted to the centrifugal rotation profile of the stirring drum 8 .

[0032] A discharge valve 13 is provided on the side of the mixing drum 8. After sufficient mixing, the mixing drum 8 stops working and is positioned against the inner surface of the outer cover 2. The outer cover 2 has a material receiving port 14 corresponding to the position of the discharge valve 13 on the mixing drum 8. The mixed plastic can be drawn out through the discharge valve 13 and finally discharged out through the material receiving port 14.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
