Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing, in particular to an asphalt mixture mixer. Background Art

[0002] When mixing asphalt, the asphalt and aggregate need to be heated to a high temperature of 100° to allow the asphalt to bond with the aggregate, so that the asphalt and aggregate need to be heated before stirring and mixing. The traditional heating method is to set a heating device in the mixer to heat the asphalt and aggregate in the mixer at the same time, but because the asphalt and aggregate are piled in the mixer, the aggregate and the asphalt are heated unevenly during heating, and the time required for the asphalt and aggregate to be heated to 100° at the same temperature is different, so that when the asphalt is heated to the predetermined temperature, the aggregate has not reached the predetermined temperature, so that the asphalt needs to be continuously heated until the aggregate is heated before stirring and mixing, which not only reduces the mixing efficiency of asphalt and aggregate, but also causes asphalt aging and affects product quality. Utility Model Content

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, an asphalt mixing machine comprises:

[0022] Box body 1, a conical box 5 is fixedly mounted on the bottom end of the box body 1;

[0023] A feed pipe 2 is symmetrically arranged in the box body 1, and a heating rod 3 is fixedly installed in the feed pipe 2;

[0024] A spiral feeding plate 4 is rotatably disposed in the feeding pipe 2 and spirally arranged on the side wall of the heating rod 3;

[0025] A mixing pipe 6 is fixedly installed in the conical box 5 and connected to the feeding pipe 2.

[0026] Specifically, when asphalt mixture needs to be made, asphalt and aggregate are respectively fed into the feed pipe 2 symmetrically arranged in the box body 1, so that the feed pipe 2 feeds the asphalt and aggregate into the mixing pipe 6 for mixing at the same time, and the asphalt and aggregate in the feed pipe 2 are heated by the heating rod 3 arranged in the feed pipe 2, so that the asphalt and aggregate are heated to a predetermined temperature during the feeding process, and the spiral feeding plate 4 is arranged in the feed pipe 2, so that the asphalt and aggregate need to roll along the spiral feeding plate 4, thereby extending the feeding time of the aggregate and asphalt, improving the heating effect, and avoiding insufficient heating of the aggregate and asphalt, and by adjusting the different heating temperatures of the heating rod 3, the asphalt and aggregate can be processed at the same time, so that the asphalt and aggregate can be stirred when entering the mixing pipe 6, thereby improving the mixing efficiency.

[0027] In the above embodiment, asphalt and aggregate are transported to the mixing tube 6 installed in the conical box 5 through two symmetrically arranged feeding pipes 2 in the box body 1, so that the asphalt and aggregate can be divided into two feeding pipes 2 and enter the mixing tube 6 at the same time for mixing, and the asphalt and aggregate are heated by the heating rod 3 installed in the feeding pipe 2, so that the aggregate and asphalt are heated to a predetermined temperature in the process of moving to the mixing tube 6, and the spiral feeding plate 4 arranged in the feeding pipe 2 makes the aggregate and asphalt roll along the spiral feeding plate 4 into the mixing tube 6, so that the heating time of the aggregate and asphalt is longer and uneven heating is avoided, and by setting different heating temperatures for the heating rod 3, the asphalt and aggregate can be heated to a predetermined temperature at the same time, so that the asphalt and aggregate can be stirred as soon as they enter the mixing tube 6, which not only improves the mixing efficiency, but also improves the product quality and effectively avoids the aging of asphalt caused by long-term heating.

[0028] As an embodiment further provided by the present invention, a symmetrically arranged annular groove 13 is provided in the feed pipe 2 .

[0029] Furthermore, a fixing block 11 is fixedly mounted on the end surface of the spiral feeding plate 4 , and a side wall of the fixing block 11 is movably connected to an annular groove 13 . Ball bearings 12 are symmetrically arranged in the fixing block 11 , and the ball bearings 12 abut against the annular groove 13 .

[0030] Specifically, a fixed block 11 is installed on the spiral feed plate 4 and connected to the annular groove 13, so that a ball 12 is installed on the side wall of the fixed block 11 to abut against the inner wall of the annular groove 13. When asphalt and aggregate fall on the spiral feed plate 4, the gravity generated by the asphalt and aggregate drives the spiral feed plate 4 to rotate, so that the fixed block 11 rotates along the annular groove 13, so that the asphalt and aggregate can be fully heated.

[0031] As another embodiment further provided by the present invention, a motor 8 is fixedly mounted on the bottom end of the box body 1 , the output end of the motor 8 extends into the mixing tube 6 , and a stirring frame 9 is fixedly mounted on the output end of the motor 8 .

[0032] Specifically, the stirring frame 9 is driven to rotate by the motor 8 so that the stirring frame 9 stirs and mixes the asphalt and aggregate falling into the mixing pipe 6, thereby forming an asphalt mixture.

[0033] As another embodiment further provided by the present invention, a heating plate 7 is fixedly installed in the conical box 5 , and the side wall of the heating plate 7 abuts against the mixing tube 6 .

[0034] Specifically, the mixing pipe 6 is heated by the installed heating sheet 7, so that the asphalt and aggregate in the mixing pipe 6 can continue to be heated during the mixing process, so that the asphalt mixture can reach a predetermined temperature when discharged.

[0035] Working principle: Asphalt and aggregate are transported to the mixing pipe 6 installed in the conical box 5 through two symmetrically arranged feeding pipes 2 in the box body 1, so that the asphalt and aggregate can enter the mixing pipe 6 from different feeding pipes 2 at the same time for mixing. When the asphalt and aggregate enter the feeding pipe 2, the heating rod 3 is driven to heat the asphalt and aggregate, so that the asphalt and aggregate are heated to a predetermined temperature during the feeding process. By adjusting the temperature of the heating rod 3, the asphalt and aggregate can be heated to a predetermined temperature at the same time. When the asphalt and aggregate enter the feeding pipe 2 and fall on the spiral feeding plate 4, the spiral feeding plate 4 The increase in gravity causes the spiral feed plate 4 to rotate. The spiral feed plate 4 rotates, causing the aggregate and asphalt to spirally roll down along the spiral feed plate 4, thereby increasing the heating time of the asphalt and the aggregate, and allowing the asphalt and the aggregate to be heated more fully. When the asphalt and the aggregate enter the mixing pipe 6, the motor 8 drives the stirring frame 9 to stir and mix the aggregate and the asphalt, so that the asphalt and the aggregate can be processed into an asphalt mixture, and the mixing pipe 6 is heated by the heating plate 7, so that the asphalt and the aggregate can continue to be heated during the mixing process, so that the asphalt mixture can be maintained at a predetermined temperature.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
