Description

Technical Field

[0001] The invention relates to the technical field of asphalt processing, and in particular to an asphalt modified mixer and a use method thereof. Background Art

[0002] In the production process of asphalt modified materials, traditional mixers have some significant technical problems, which directly affect the production efficiency, the uniformity of material mixing and the cleanliness of the production environment. First, traditional mixers have limitations in raw material input and mixing. Since there is usually only one feed port and the mixing method is relatively single, it is difficult to achieve sufficient and uniform mixing of different types of raw materials in a short time. This not only reduces production efficiency, but also may lead to unstable quality of mixed materials, thus affecting the overall performance of asphalt modified materials. Secondly, material blockage and dust pollution are another major problem faced by traditional mixers. During the mixing process, materials are easy to adhere to the inner wall of the agitator or conveying pipeline, causing blockage and affecting the smoothness of material flow. At the same time, the dust generated during the mixing process is difficult to collect and treat effectively, which is easy to pollute the production environment and endanger the health of workers. In addition, the design of traditional mixers is often large and complex, and the connection and transmission methods between the various components are not flexible enough, resulting in poor stability of the equipment during operation and difficulty in daily cleaning and maintenance.

[0021] Reference Figure 1-Figure 9 , an asphalt modified mixer, mainly composed of a mixing box 1. A feeding part 2 is installed on the top of the mixing box 1 for the initial addition of raw materials. Three groups of guide parts 3 are arranged alternately inside the mixing box 1 to enhance the flow and mixing effect of the materials in the mixing box. At the top of the second group of guide parts 3, a feeding part 2 4 is provided for adding the second or subsequent raw materials. A beating part 5 is installed at the bottom of each guide part 3 and feed part 2 4. When the beating part rotates, it will beat the bottom of the guide part to help the material fall and prevent blockage. The inner wall of the mixing box 1, below the guide part 3, is equipped with a stirring part 6 for stirring and mixing the materials. A suction part 7 is installed on one side of the mixing box 1 for collecting dust in the mixing box. The dust is sucked into the air storage box 8 for storage through the suction part 7.

The material guiding part 3 includes a sliding seat 31 installed at the mixing part 1, and an inner cavity 311 is opened in the sliding seat 31. An electric heating plate 312 is arranged in the inner cavity 311. The electric heating plate 312 is used to heat the material flowing at the sliding seat 31. Through the setting of the electric heating plate 312, the material flowing at the sliding seat 31 can be laid flat, so that the heating effect is better and more uniform during heating.

[0022] In the present invention, the feed part 2 includes a material guide seat 21 installed on the top of the mixing box 1, a cavity 22 is provided on the top of the material guide seat 21, and a feed port 23 is provided on the top of the cavity 22. A rotatable transmission shaft 24 is installed in the cavity 22, and a transmission blade 25 is installed on the surface of the transmission shaft 24. When the raw material enters the cavity 22 from the feed port 23, the transmission shaft 24 drives the transmission blade 25 to rotate, and the raw material is evenly fed into the mixing box 1. This design ensures that the raw material can enter the mixing box evenly and continuously, avoiding the problems of blockage and uneven distribution of raw materials.

[0023] In the present invention, a stirring motor 61 is installed on the surface of the mixing box 1, and a stirring rod 62 is installed at the output end of the stirring motor 61. The stirring rod 62 is rotatably connected to the inner wall of the mixing box 1 through a bearing and penetrates the outside of the mixing box 1.

When the transmission shaft 24 rotates, the rotating rod 51 is driven to rotate through the belt member 2 54, and then the beating rod 52 is driven to beat the bottom of the sliding material seat 31. This design ensures that the beating part 5 can work with the rotation of the transmission shaft 24, and effectively prevents the material from being blocked at the bottom of the sliding material seat 31.

[0025] In the present invention, the extraction part 7 includes a temporary storage tube 71 installed on the side of the mixing box 1, a piston rod 72 is inserted into the inner wall of the temporary storage tube 71, and a connecting spring 73 is installed between the piston rod 72 and the inner wall of the temporary storage tube 71.

A discharge pipe 76 is also installed on the top of the temporary storage tube 71, and the discharge pipe 76 is inserted into the air storage box 8. Check valves are installed at the extraction pipe 74 and the discharge pipe 76. When the piston rod 72 moves under the drive of the transmission part 9, the dust in the mixing box 1 is sucked into the temporary storage tube 71 through the extraction head 75, and then discharged into the air storage box 8 through the discharge pipe 76, thereby realizing the effective collection and storage of dust.

[0026] In the present invention, the material guide part 3 includes a sliding seat 31 installed on the inner wall of the mixing box 1, a reset member 32 is installed at the bottom of the sliding seat 31, a scraper plate 33 is slidably connected to the inner wall of the sliding seat 31, and the reset member 32 is used to reset the scraper plate 33. A baffle plate 34 is installed on the top of the sliding seat 31, and a material discharge trough 35 is opened at the bottom of the baffle plate 34. When the scraper plate 33 moves under the pressure of the material, the reset member 32 will reset it, pushing the material attached to the inner wall of the sliding seat 31 to be discharged through the discharge chute 35. This design ensures that the material can be discharged smoothly from the sliding seat 31, reducing the residual material in the mixing box. A guide rod 36 is installed at the inner wall of the sliding seat 31, and the scraper plate 33 is connected with the guide rod 36. A limit plate 37 is installed at the end of the guide rod 36 for limiting the scraper plate 33.

This design realizes the linkage of the stirring part 6 and the material extraction part 7, and improves the working efficiency and automation of the mixer.

[0028] A method for using an asphalt modified mixer comprises the following steps: asphalt is transported from a feed section 1 2 into a mixing box 1, and then gradually flows downward through a top material guide section 3, and when falling to the middle material guide section 3, a modifier is transported from the feed section 2 4 to the middle material guide section 3 through a set feed section 2 4, and at this time, asphalt and modifier continuously flow in the material guide section 3, thereby achieving a mixing effect; when mixing, the material guide section 3 is continuously tapped by a flapping section 5, thereby achieving an oscillating effect on the material guide section 3, further ensuring an effect of mixing the asphalt and the modifier when flowing; and then finally the mixture falls to the top of the inner bottom wall of the mixing box 1, and is stirred by a set stirring section 6, thereby ensuring an effect of mixing; finally, through the setting of a transmission section 9, the extraction section 7 is driven to extract the dust generated in the mixing box 1 due to oscillation, mixing and stirring into an air storage box 8 for storage, so as to facilitate subsequent recycling and treatment.

[0029] The specific working principle of the present invention is as follows: the operator puts the raw material into the cavity 22 through the feed port 23 of the feed part 2, and the transmission shaft 24 starts to rotate under the action of the driving device, driving the transmission blades 25 to evenly feed the raw material into the mixing box 1. At the same time, the stirring motor 61 is started, driving the stirring rod 62 and the stirring blades 63 to rotate, and the raw materials entering the mixing box 1 are preliminarily mixed. After the initial mixing, the raw materials enter the sliding seat 31 of the guide part 3, and the scraper plate 33 slides along the guide rod 36 under the material pressure. When the material pressure decreases or disappears, the reset spring 322 pushes the scraper plate 33 to reset, and the material attached to the inner wall of the sliding seat 31 is discharged through the discharge chute 35. In this process, the rotating rod 51 of the flapping part 5 rotates in conjunction with the transmission shaft 24 through the belt part 2 54, driving the flapping rod 52 to flap the bottom of the sliding seat 31 to prevent material blockage. When the second or subsequent raw materials need to be added When the material is mixed, the operator puts it into the mixing box 1 through the feeding part 24. These raw materials are further mixed with the raw materials mixed for the first time under the action of the stirring blades 63. During the mixing process, the dust generated in the mixing box 1 is sucked into the temporary storage tube 71 through the extraction head 75 of the extraction part 7. When the stirring rod 62 rotates, the half gear 91 engages with the rack 92, driving the connecting rod 93 and the piston rod 72 to move in the temporary storage tube 71. The movement of the piston rod 72 discharges the dust in the temporary storage tube 71 through the discharge pipe 76 into the air storage box 8 for storage. When the raw material mixing meets the predetermined requirements, the stirring motor 61 and the transmission device are turned off, and the discharge port at the bottom of the mixing box 1 is opened. It is not explicitly mentioned in the claims, but the mixer usually has a discharge device to discharge the mixed materials. After completing a mixing task, the mixer is cleaned and maintained as necessary, including cleaning the dust in the air storage box 8 and checking the wear of each component.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
