Description

Technical Field

[0001] This utility model relates to the field of asphalt unloading bin technology, specifically an asphalt mixing plant unloading bin. Background Technology

[0002] The unloading silo of an asphalt mixing plant is a crucial link in the asphalt mixture production process. It is mainly used to store and unload finished asphalt mixtures, balancing the differences in production and transportation schedules. After being unloaded from the unloading silo, the mixture is transported to storage silos, loading points, or subsequent processing stages.

[0003] Due to the high temperature, viscosity, and segregation characteristics of asphalt mixtures, the mixture tends to adhere to the bin walls during actual unloading. Relying solely on natural flow for unloading can easily cause blockages at the unloading port, resulting in a mismatch between the unloading speed and the production and transportation rhythm, leading to material jamming at the discharge point. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an asphalt mixing plant unloading bin, including a bin 1, the lower end of the bin 1 is connected to a first unloading pipe 2, the lower end of the first unloading pipe 2 is connected to a guide hopper 3, the guide hopper 3 is connected to a second unloading pipe 4, the first unloading pipe 2 has an unloading assembly 21 built in it, the unloading assembly 21 includes a gear transmission box 211, the output shaft of the gear transmission box 211 is connected to a first rotating rod 212, a first spiral blade 213 is welded and fixed on the first rotating rod 212, a second motor 41 is installed at one end of the second unloading pipe 4, the output shaft of the second motor 41 is fixedly connected to a second rotating rod 42, a second spiral blade 43 is welded and fixed on the second rotating rod 42.

[0025] When the first rotating rod 212 rotates under the drive of the first motor 217, it drives the first spiral blade 213 to rotate synchronously. The rotating first spiral blade 213 conveys the mixture and pushes the mixture downward along the first discharge pipe 2 to achieve vertical conveying of the mixture.

[0026] When the second motor 41 is working, it drives the second rotating rod 42 to rotate. The second rotating rod 42 drives the second spiral blade 43 to rotate synchronously. The rotating second spiral blade 43 conveys the mixture and pushes the mixture to move horizontally along the second discharge pipe 4, thereby realizing the horizontal conveying of the mixture.

[0027] The first unloading pipe 2 forms the first spiral conveying assembly, and the second unloading pipe 4 forms the second spiral conveying assembly. The first spiral blade 213, the second spiral blade 43, and the inner wall structure of the equipment are all treated with an anti-stick coating. The mixture inside the silo 1 first enters the first unloading pipe 2, then enters the guide hopper 3 through the first unloading pipe 2, and then enters the second unloading pipe 4 through the guide hopper 3. Finally, it is unloaded through the discharge pipe 5 at the end of the second unloading pipe 4. Two sets of spiral conveying assemblies are added at the lower end of the silo 1 to convey the mixture vertically and horizontally, respectively. The mixture moves under the combined action of gravity and spiral thrust, reducing the risk of blockage, jamming, adhesion, and segregation of the mixture. The conveying volume can be precisely controlled by frequency conversion speed regulation to adapt to the loading speed of different vehicle models.

[0028] The gear transmission box 211 contains a first bevel gear 214 and a second bevel gear 215. The first bevel gear 214 meshes with the second bevel gear 215 for transmission. The second bevel gear 215 is fixedly connected to the main shaft 216. The main shaft 216 is driven by a first motor 217, and the output shaft of the first motor 217 is fixedly connected to the main shaft 216 through a coupling. The first bevel gear 214 is fixedly connected to the first rotating rod 212.

[0029] When the first motor 217 is working, it drives the main shaft 216 at one end to rotate. The main shaft 216 drives the second bevel gear 215 at one end to rotate. Through the meshing transmission between the teeth, the second bevel gear 215 drives the first bevel gear 214 to rotate. The first bevel gear 214 drives the first rotating rod 212 to rotate, thereby realizing the spiral conveying.

[0030] The first motor 217 is installed on the outer side of the first discharge pipe 2. The first motor 217 does not come into contact with the mixture to prevent the first motor 217 from overheating. The external structure of the first motor 217 is conducive to heat dissipation and daily maintenance.

[0031] The second unloading pipe 4 is equipped with a feed inlet 44 and a discharge outlet 45.

[0032] The feed inlet 44 is connected to the guide hopper 3, and the discharge outlet 45 is connected to the discharge pipe 5. The mixture is transported to the guide hopper 3 through the first discharge pipe 2. The mixture discharged from the guide hopper 3 enters the second discharge pipe 4 through the feed inlet 44 of the second discharge pipe 4. The second discharge pipe 4 horizontally transports the mixture, and the mixture is finally discharged through the discharge pipe 5.

[0033] The discharge pipe 5 includes a corrugated hose 51 and a straight pipe 52. The corrugated hose 51 is sealed and fixed to the discharge port 45. The corrugated hose 51 is a flexible component that serves as a connector to connect the straight pipe 52 and the discharge port 45. The corrugated hose 51 can be bent, which allows for flexible adjustment of the discharge direction and position of the straight pipe 52, as well as flexible adjustment of the end discharge position, thereby improving the flexibility of the unloading process.

[0034] The top of the silo 1 is equipped with a feeding port 11. The asphalt mixture after processing by the asphalt mixing plant enters the silo 1 through the feeding port 11 and is then unloaded through the silo 1.

[0035] The lower end of the silo 1 is provided with a feeding hopper 12, and the feeding hopper 12 is sealed and fixed with the first unloading pipe 2. The feeding hopper 12 performs preliminary material guiding of the mixture.

[0036] The first unloading pipe 2 has a built-in crossbar 22, and the unloading assembly 21 is installed on the crossbar 22.

[0037] Working principle: During operation, the asphalt mixture processed by the asphalt mixing plant enters the silo 1 through the feed inlet 11 and is then discharged through the silo 1. When the first rotating rod 212 rotates under the drive of the first motor 217, it drives the first spiral blade 213 to rotate synchronously. The rotating first spiral blade 213 conveys the mixture and pushes the mixture downward along the first discharge pipe 2, achieving vertical conveying of the mixture. When the second motor 41 is working, it drives the second rotating rod 42 to rotate, and the second rotating rod 42 drives the second spiral blade. The second spiral blade 43 rotates synchronously and conveys the mixture through the rotating second spiral blade 43. The second spiral blade 43 pushes the mixture to move horizontally along the second discharge pipe 4, realizing the horizontal conveying of the mixture. The mixture inside the hopper 1 first enters the first discharge pipe 2, then enters the guide hopper 3 through the first discharge pipe 2, and then enters the second discharge pipe 4 through the guide hopper 3. Finally, it is discharged through the discharge pipe 5 at the end of the second discharge pipe 4. The corrugated hose 51 is a flexible component and serves as a connector to connect the straight pipe 52 and the discharge port 45. The corrugated hose 51 can be bent to flexibly adjust the end discharge position.
