Description

Technical Field

[0001] The utility model relates to the technical field of waste tire processing, in particular to a material pushing device and a material feeding device for processing waste tires. Background Art

[0002] The waste tires are transported forward during the pyrolysis process and are evenly heated during the material reaction process. A pyrolysis kettle is generally used as a reaction vessel for the pyrolysis of waste tires. Specifically, the waste tires are fed into the pyrolysis kettle through a feeding port by a feeding device for rotational pyrolysis.

[0003] At present, there is a pushing screw conveyor at the feeding port to push the material. With the help of the rotation of the screw conveyor's auger shaft, the material fills the auger, preventing the air from flowing in the auger, and the material is pushed forward by the twisted blades on the auger shaft, slowly moving toward the outlet to achieve the purpose of sealing and conveying the material. Since the feeding device is directly connected to the pyrolysis kettle, it is particularly important to ensure the sealing of the feeding device in order to ensure the sealing of the pyrolysis kettle.

[0004] Since the pitch between the twisted blades affects the material conveying process, when the conveying volume and blade diameter are constant, the change in pitch will change the sliding surface of the material movement, resulting in a change in the material movement speed. When the pitch increases, the axial conveying speed is high, but the circumferential speed is low, and the filling coefficient is relatively small, which leads to poor sealing effect. On the contrary, although the sealing effect is good, the axial conveying speed is low and the power consumption is high. In the prior art, the twisted blades of the auger shaft are generally evenly spaced, so it is impossible to meet the sealing effect while ensuring the conveying efficiency, which leads to the inability to achieve both sealing and axial speed.

[0029] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. The directional terms "upper", "lower", "inner" and "outer" mentioned herein are based on the orientation of the drawings.

[0030] Reference Figure 1-2 As shown, a pushing device for processing waste tires proposed in an embodiment of the utility model includes a conveying barrel 1, an auger shaft 2 and a supporting body 3.

[0031] See also Figure 1 As shown, one end of the conveying barrel 1 is connected to the supporting body 3, and the other end of the conveying barrel 1 extends to one end of the pyrolysis kettle. A feeding port 11 is provided at one end of the conveying barrel 1 close to the supporting body 3. The auger shaft 2 is supported by the supporting body 3 to ensure that the auger shaft 2 is horizontal in the axial direction, thereby improving the feeding effect at the right end of the feeding barrel 1.

[0032] The auger shaft 2 is arranged in the conveying barrel 1 , and one end of the auger shaft 2 passes through the conveying barrel 1 and the supporting body 3 and is connected to a driving member that drives the auger shaft 2 to rotate.

[0033] In this embodiment, the auger shaft 2 includes a first sealing section 21 and a pushing section 22. The first sealing section 21 is located at the feed inlet 11, and one end of the first sealing section 21 is connected to the driving member, and the other end is connected to one end of the pushing section 22.

[0034] The utility model is a pusher device for processing waste tires. By arranging a first sealing section 21 and a pusher section 22 on the auger shaft, and the first sealing section 21 is arranged at the feed port 11, sealing can be achieved. By arranging the pusher section 22 away from the feed port, the feeding efficiency is ensured, which not only satisfies the sealing effect of the auger shaft 2 but also ensures the conveying efficiency. The utility model solves the technical problem that the sealing effect cannot be satisfied while the conveying efficiency cannot be ensured, and thus the sealing performance and the axial speed cannot be achieved at the same time.

[0035] Furthermore, the first sealing section 21 includes a plurality of first hinged leaves 211, and the distance between two adjacent first hinged leaves 211 is a first pitch l.

[0036] Furthermore, the pushing section 22 includes a plurality of second twisted leaves 221, and the distance between two adjacent second twisted leaves 221 is a second spiral h.

[0037] Furthermore, the ratio of the first pitch l to the second pitch h is 0.85-0.9 times. The preferred pitch ratio is 0.85 times. It is to be noted that after summarizing multiple data, it is found that the pitch ratio of 0.85 times can make the sealing effect and the pushing effect in the best state, that is, while ensuring the sealing, the pushing effect is also in the best state.

[0038] Furthermore, the auger shaft 2 also includes a second sealing section 23, and the other end of the pushing section 22 is connected to the second sealing section 23, and the second sealing section 23 is located near the discharge port of the pyrolysis kettle. The addition of the second sealing section 23 at the discharge port can seal the material from both sides, thereby improving the sealing effect.

[0039] Furthermore, the pitch of the hinged blades of the second sealing section 23 is the same as the pitch of the first hinged blades 211 of the first sealing section 21. This simplifies the process and reduces the manufacturing cost.

[0040] Furthermore, the support body 3 includes a support cylinder 31, a roller bearing 32 and a sealing ring 33. The support cylinder 31 is detachably connected to the conveying barrel 1, and the roller bearing 32 is located between the auger shaft 2 and the support cylinder 31, and is used to support the auger shaft 2. The sealing ring 33 is arranged on an end surface of the support cylinder 31 close to the driving member, and is sleeved on the outer wall of the auger shaft 2. The support body 3 can further seal the end of the feed barrel 1 close to the feed port 11 to prevent air leakage, thereby affecting the sealing effect and the pushing effect. In comparison, this embodiment can avoid sealing at one end of the feed port 11, thereby ensuring the support effect and sealing performance.
