Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt crushing, and in particular relates to asphalt crushing equipment. Background Art

[0002] Asphalt is an important road construction material, and its resources are relatively limited. By crushing waste asphalt pavement, the asphalt and mineral materials in it can be recovered and reused, thereby reducing the demand for new resources and achieving the goal of saving resources.

[0003] For example, the Chinese patent with the publication number CN211070398U discloses a solid asphalt crushing device, including a first crushing box and a rotating grinding disc, the top of the first crushing box is provided with a feed port, the crushing cylinder is arranged in the first crushing box, and a drainage frame is arranged on the lower side of the crushing cylinder, a fixed grinding disc is arranged on the outer side of the bottom of the drainage frame, and the fixed grinding disc is fixed in the first crushing box by a first bolt, the bottom of the first crushing box is connected to the second crushing box by a second bolt, and a motor box is fixed inside the second crushing box, the rotating grinding disc is connected to the upper side of the second motor by a second motor shaft, and the rotating grinding disc is arranged on the lower side of the fixed grinding disc, and a discharge port is provided at the bottom of the second crushing box, and a bracket is arranged on the outer side of the discharge port. In the solid asphalt crushing device, after the material enters between the fixed grinding disc and the rotating grinding disc, it can be crushed twice under the extrusion of the fixed grinding disc and the rotating grinding disc, thereby improving the crushing effect.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when the above device is crushing, asphalt with smaller particles that do not need to be crushed will also be crushed, resulting in reduced crushing efficiency and wasted time. At the same time, after the above device has crushed the asphalt, there will be impurities on the asphalt, which requires manual cleaning by personnel, wasting time. In view of this, we propose an asphalt crushing device. Utility Model Content

[0006] The purpose of the utility model is to provide an asphalt crushing device to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides an asphalt crushing device, comprising:

[0008] A crushing shell, wherein a crushing chamber is provided in the crushing shell, a filter screen 1 is rotatably installed in the crushing chamber, an elliptical cylinder is rotatably installed in the crushing chamber and at the bottom of the filter screen 1, the top of the elliptical cylinder is tightly fitted with the bottom of the filter screen 1, and two crushing rollers are rotatably installed in the crushing chamber and below the elliptical cylinder;

[0009] A driving assembly, which is located on the crushing shell and is used to drive the two crushing rollers to rotate and the elliptical cylinder to rotate;

[0010] A connecting pipe, the connecting pipe is fixedly installed at the bottom of the crushing shell, a cleaning tank is fixedly installed at one end of the connecting pipe, a drying chamber is opened in the cleaning tank, an electric heating wire is fixedly installed in the drying chamber, two rotating columns are rotatably installed in the inner cavity of the cleaning tank, a plurality of stirring blades are fixedly installed on the rotating columns, a connecting rod is fixedly installed on one of the rotating columns, and the other end of the connecting rod is rotatably connected to the other rotating column;

[0011] A power assembly is located on the cleaning tank and is used to drive the two rotating columns to rotate.

[0012] In the technical scheme, when the asphalt needs to be crushed, the driving assembly is set up to drive the two crushing rollers to rotate in opposite directions and the elliptical cylinder to rotate. The elliptical cylinder will knock the bottom of the filter screen one, causing the filter screen one to rotate upward, and then under the action of gravity, the filter screen one rotates downward. The personnel then pour the asphalt into the crushing chamber, and then the asphalt falls to the top of the filter screen one. After being filtered by the filter screen one, the asphalt with smaller particles falls directly to the bottom of the crushing chamber, and the asphalt with larger particles falls to the top of the two crushing rollers. Then the asphalt with larger particles is crushed by the two crushing rollers and falls to the bottom of the crushing chamber. Finally, all the crushed asphalt enters the cleaning tank through the connecting pipe, ensuring that the asphalt with smaller particles does not need to be crushed, thereby speeding up the crushing efficiency.

[0013] Then pour the water and detergent into the cleaning tank through the feed pipe. Through the set power component, one of the rotating columns can be driven to rotate, and through the set power component, another rotating column can be driven to rotate and rotate on its own. The other rotating column drives the corresponding several stirring blades to rotate and rotate on their own. The several stirring blades can stir and mix the asphalt, water and detergent in the cleaning tank to ensure that the asphalt can be cleaned. After the asphalt is cleaned, the water and detergent are discharged to the outside. After the water and detergent are discharged, the personnel start the electric heating wire, which will dry the remaining water and detergent on the asphalt, and the steam generated by the drying is discharged to the outside. When the asphalt is dried, it is discharged to the outside, which can clean the dirt on the asphalt to ensure that the asphalt can be reused.

After being filtered by the filter screen 1, the asphalt with smaller particles falls directly to the bottom of the crushing chamber, and the asphalt with larger particles falls to the top of the two crushing rollers. Then the asphalt with larger particles is crushed by the two crushing rollers and then falls to the bottom of the crushing chamber. Finally, all the crushed asphalt enters the cleaning tank through the connecting pipe, ensuring that the asphalt with smaller particles does not need to be crushed, thereby speeding up the crushing efficiency.

[0018] In the above technical solution, further, the power assembly includes:
