Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a warm-mix construction device for steel slag modified asphalt. Background Technology

[0002] Steel slag modified asphalt is a new type of road construction material with environmental value and promising engineering applications. Its production process has high requirements for temperature control, mixing uniformity, and construction continuity. Its core process is to eliminate the instability of free calcium oxide by crushing, screening, aging and other physical and chemical treatments of industrial waste slag generated during steel smelting. This waste slag is then used to replace the natural basalt or limestone aggregate in traditional asphalt mixtures. It is then mixed and compounded with high-performance asphalt with modifiers such as SBS and rubber powder under specific temperature conditions to form a green paving material with excellent high-temperature stability, low-temperature crack resistance and durability.

[0003] Currently, conventional warm-mix construction equipment mostly adopts a single mixing drum structure. After the steel slag and modified asphalt are mixed, the material needs to be discharged manually or semi-automatically through the bottom outlet. This means that the next batch of mixing can only be carried out after the previous discharge is completed. This intermittent operation not only reduces the utilization rate of the equipment, but also affects the overall construction efficiency. The mixing efficiency is not high. Moreover, after the steel slag modified asphalt mixture is discharged, the temperature is prone to drop rapidly due to the ambient temperature difference. Especially in cold regions or under strong wind conditions, the surface of the mixture is prone to crusting and segregation occurs inside, affecting the paving quality and road performance.

[0004] Therefore, it is necessary to design a warm-mix construction device for steel slag modified asphalt to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the aforementioned shortcomings, the technical problem of this utility model is to provide a warm-mix construction device for steel slag modified asphalt.

Detailed Implementation

[0022] Example: A warm-mix construction device for steel slag modified asphalt, such as... Figures 1-6As shown, the system includes a base 1, a storage frame 2, a mixing tank 4, a connecting pipe 3, a motor 5, a stirring rod 501, a heating element 6, a first baffle 7, a pull rope 8, a first guide rod 9, a first spring 10, a locking strip 11, a handle 12, and a second spring 13. The storage frame 2 is fixedly connected to the rear of the base 1, and the mixing tank 4 is fixedly connected to the top of the storage frame 2. The mixing tank 4 is tilted at a 45-degree angle. The lower rear side of the mixing tank 4 is connected to the front top of the storage frame 2 via a connecting pipe 3. The motor 5 is bolted to the middle of the upper part of the mixing tank 4. The output shaft of the motor 5 passes through the mixing tank 4 and is fixedly connected to the stirring rod 501. Multiple heating elements 6 are fixedly connected to the left and right sides of the storage frame 2 and the outer side of the mixing tank 4. The heating elements 6 on the mixing tank 4... Arranged in a ring array, the mixing tank 4 is rotatably connected to a first baffle 7, which is made of high-density polyethylene. The first baffle 7 has locking blocks on both sides and a pull rope 8 is fixedly connected between the left and right sides of the first baffle 7. The first guide rod 9 is bolted to both sides of the first baffle 7. The first guide rod 9 is semi-circular and each first guide rod 9 is connected to the first baffle 7 with a corresponding first spring 10. The first baffle 7 is slidably connected to the left and right sides with locking strips 11. The locking strips 11 slide on the connecting pipe 3 and have multiple locking slots corresponding to the locking blocks. Each locking strip 11 has a handle 12 bolted to its front side. The connecting pipe 3 has a second spring 13 connected between the left and right sides of the connecting strip 11 at the corresponding positions.

[0023] When this device is needed, the pretreated steel slag aggregate and modified asphalt are first added from the top of the mixing drum 4. Then, the motor 5 is started. The output shaft of the motor 5 drives the mixing rod 501 to rotate at high speed, which fully mixes the pretreated steel slag aggregate and modified asphalt. At the same time, the heating pipes 6 arranged around the outside of the mixing drum 4 provide continuous heat to ensure that the mixture is always within a suitable warm mixing temperature range, thereby improving the uniformity of the material and its adaptability to construction.

[0024] After mixing is complete, the operator pulls both handles 12 simultaneously, compressing the second spring 13 and causing the latches on the two locking strips 11 to disengage from the locking blocks on the first baffle 7. At this time, the first spring 10 is compressed, and the first baffle 7 is rotated open. After rotating to a certain angle and aligning the locking blocks with the locking slots, the two handles 12 are released, and the second spring 13 resets, causing the locking strips 11 to reset. The locking blocks are inserted into the locking slots, continuing to restrict the first baffle 7. The mixed asphalt mixture enters the storage frame 2 through the connecting pipe 3 for temporary storage, and the heating pipe 6 of the storage frame 2 continues to maintain a suitable temperature.

[0025] like Figures 1-5 and Figure 6As shown, it also includes a second baffle 14, a pull rod 15, a second guide rod 16, a third spring 17, an observation window 18, and a guide hopper 19. The storage frame 2 is slidably connected to the lower part of the second baffle 14. The pull rod 15 is bolted to the rear side of the second baffle 14. The second guide rods 16 are fixedly connected to both the left and right sides of the second baffle 14. The second guide rods 16 are slidably connected to the storage frame 2. The two second guide rods 16 are respectively connected to the lower left and right sides of the storage frame 2 and the third springs 17 are connected to them. The observation window 18 is fixedly connected to the middle of the front side of the storage frame 2. The guide hopper 19 is bolted to the rear side of the base 1 and is located at the lower part of the storage frame 2. The guide hopper 19 is tilted at 30 degrees.

[0026] The storage box 2 has a sliding second baffle 14 at the bottom. By pulling the pull rod 15, the second guide rod 16 and the second baffle 14 are moved, and the third spring 17 is compressed. At this time, the stored mixture can be discharged through the guide hopper 19 to the transport vehicle or paver for use. When the pull rod 15 is released, the third spring 17 returns to its original position, which drives the second baffle 14 and the second guide rod 16 to return to their original position. The third spring 17 achieves elastic locking. In addition, the observation window 18 facilitates real-time monitoring of the material level in the storage box 2. The guide hopper 19 adopts a 30-degree tilt design to improve the smoothness of material discharge.
