Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a fiber uniform dispersion device for ECC bridge deck casting. Background Technology

[0002] ECC material is a high-performance cement-based composite material composed of cement, mineral admixtures, aggregates, fibers, and additives. Among them, fibers, as the reinforcing phase, play a core role in improving the mechanical properties of ECC materials. However, in the actual construction of ECC bridge deck casting, the uniform dispersion of fibers faces many challenges.

[0003] When existing mixers mix ECC materials containing fibers, the design of the mixing blades and the mixing mode are relatively simple, making it difficult to generate a sufficiently complex flow field to effectively disperse the fibers. During the mixing process, the fibers tend to entangle and aggregate to form clusters. These clusters are unevenly distributed in the ECC material, resulting in local areas with excessively high or low fiber content. This uneven fiber distribution directly leads to increased dispersion in the mechanical properties of ECC bridge decks, which cannot meet the stringent requirements of modern bridge engineering for structural consistency and reliability.

[0004] An existing patent (publication number: CN221314675U) discloses an uncoated PVA fiber dispersion device for concrete. The static electricity generated by the friction between the fiber and the high-speed airflow is beneficial to the rapid dispersion of the fiber. The time required for the fiber to be evenly dispersed in the mixing equipment is taken into account, which is beneficial to the uniform dispersion of the fiber in the cement matrix. The pressure difference is used to drive the airflow to perform self-cleaning of the equipment, so that the fiber loss during the dispersion process is reduced.

[0005] To address the aforementioned problems, existing patents offer solutions, but they are not convenient for breaking up fiber clumps. During the packaging and transportation of fiber raw materials, fibers easily become entangled into large, tightly packed clumps. When these fiber clumps enter the existing device, due to the lack of an effective mechanism specifically designed to break them up, high-speed airflow alone is insufficient to completely disperse them. The stirring process is also ineffective because the fiber clumps are large, resulting in the fiber clumps remaining in clump form within the ECC material. This severely affects the uniform distribution of fibers in the material and reduces the practicality of the device.

[0006] To address this, a fiber uniform dispersion device for ECC bridge deck casting is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a fiber uniform dispersion device for ECC bridge deck casting, which solves the problem that existing fiber uniform dispersion devices for ECC bridge deck casting are not convenient for breaking up fiber clumps. During the packaging and transportation of fiber raw materials, fibers easily become entangled into large, tightly packed clumps. When these fiber clumps enter the existing device, due to the lack of an effective mechanism specifically for breaking up the fiber clumps, it is difficult to completely break up the fiber clumps by relying solely on high-speed airflow. The stirring process is also unable to fully play its role due to the large size of the fiber clumps, resulting in the fiber clumps still existing in clumps in the ECC material, which seriously affects the uniform distribution of fibers in the material and reduces the practicality of the device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fiber uniform dispersion device for ECC bridge deck casting, comprising a tank, wherein a mixing component is fixedly connected inside the tank and a dispersion component is fixedly connected to the top of the tank, the mixing component comprising a mixing motor, wherein a rotating rod is fixedly connected to the output end of the mixing motor and the mixing motor is located on the front side of the tank;

[0016] Preferably, a support plate is movably connected to the top of the base, the top of the support plate is fixedly connected to the bottom of the tank, and several buffers are fixedly connected to the bottom of the support plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A fiber uniform dispersion device for ECC bridge deck casting includes a tank 1, a mixing component 2 fixedly connected inside the tank 1, and a dispersion component 3 fixedly connected to the top of the tank 1. The mixing component 2 includes a mixing motor 201, a rotating rod 202 fixedly connected to the output end of the mixing motor 201, and the mixing motor 201 is located on the front side of the tank 1.

[0029] The dispersion component 3 includes an inlet pipe 301. Grinding rollers 302 are rotatably connected to the front and rear sides of the inlet pipe 301. Rotary motors 303 are fixedly connected to the right sides of the two grinding rollers 302. A top cover plate 304 is movably connected to the top of the inlet pipe 301. An inlet valve 305 is fixedly connected to the bottom of the inlet pipe 301. A pressurizing fan 306 is fixedly connected to the rear side of the inlet pipe 301. An air supply pipe 307 is provided between the pressurizing fan 306 and the inlet pipe 301.

[0030] In this embodiment: the combined use of the suction pipe 6 and the louvers 7 not only increases the suction range but also filters impurities in the outside air. Simultaneously, under the action of the pressurizing fan 306, the filtered air flows smoothly into the interior of the pipe 301 through the air delivery pipe 307, thereby driving the smooth movement of the fibers, protecting the pressurizing fan 306, reducing the probability of fan failure, and improving the service life of the dispersing component 3. Then, by rotating the motor 303 to drive the grinding roller 302 to rotate smoothly, the fiber clumps can be broken up. Simultaneously, under the action of the inlet valve 305, the broken fibers can be smoothly blown into the interior of the tank 1. The mixing component 2 ensures the quality of the ECC bridge deck casting and improves the ease of use of the dispersing component 3. Then, the mixing motor 201 drives the rotating rod 202 to rotate, which in turn drives the connecting plate 205 and the cross fixing plate 203 to rotate, and simultaneously drives the stirring blade 204 to rotate. This allows the raw materials and fibers inside the tank 1 to flow, thereby ensuring the full mixing of the raw materials and fibers and improving the ease of use of the device. Then, under the action of the scraper 206, the scraper 206 moves along the inner wall of the tank 1, which can scrape off the material attached to the inner wall of the tank 1, avoiding the accumulation of material residues that interfere with the subsequent mixing process and improving the ease of use of the mixing component 2.

[0031] Specifically, such as Figure 4 As shown, the rotating rod 202 extends into the tank 1 from the side away from the mixing motor 201. The front and rear sides of the rotating rod 202 are fixedly connected with cross fixing plates 203, and stirring blades 204 are rotatably connected to the four corners of the opposite side of the two cross fixing plates 203.

[0032] Specifically, such as Figure 4 As shown, a connecting plate 205 is fixedly connected to the front side of the rotating rod 202, and the connecting plate 205 is located in front of the cross fixing plate 203. Scrapers 206 are fixedly connected to both sides of the rear side of the connecting plate 205, and the surface of the scraper 206 is in contact with the inner wall of the tank 1.

[0033] Specifically, such as Figure 3 As shown, a rotating hole 4 is provided on the front side of the tank body 1 to cooperate with the rotating rod 202, and the surface of the rotating rod 202 is in contact with the inner wall of the rotating hole 4.

[0034] In this embodiment: the mixing motor 201 drives the rotating rod 202 to rotate, which in turn drives the connecting plate 205 and the cross fixing plate 203 to rotate, and simultaneously drives the stirring blade 204 to rotate. This causes the raw materials and fibers inside the tank 1 to flow, thereby ensuring that the raw materials and fibers are fully mixed and improving the ease of use of the device. Then, under the action of the scraper 206, the scraper 206 moves along the inner wall of the tank 1, which can scrape off the material attached to the inner wall of the tank 1, ensuring the cleanliness of the inside of the tank 1 and avoiding the interference of material residue accumulation on the subsequent mixing process. Therefore, it is not necessary to frequently perform deep cleaning and maintenance on the tank 1, saving manpower and time costs and improving the ease of use of the mixing component 2.

[0035] Specifically, such as Figure 3 As shown, the top of the tank body 1 is provided with a mounting hole 5 for use with the inlet valve 305, and the surface of the inlet valve 305 is in contact with the inner wall of the mounting hole 5.

[0036] Specifically, such as Figure 5 As shown, an air intake pipe 6 is fixedly connected to the rear side of the pressurizing fan 306, and a louver 7 is fixedly connected to the side of the air intake pipe 6 away from the pressurizing fan 306.

[0037] In this embodiment: the combined use of the suction pipe 6 and the louvers 7 increases the suction range and filters impurities in the outside air, allowing air to flow smoothly into the inlet pipe 301 through the pressurizing fan 306, protecting the pressurizing fan 306, reducing the probability of fan failure, and increasing the service life of the dispersion component 3. Simultaneously, the combined use of the inlet valve 305 and the mounting hole 5 makes the inlet valve 305 connection more secure, enabling the fibers to be smoothly blown into the interior of the tank 1, preventing impurities from mixing into the raw materials, ensuring the quality of ECC bridge deck casting, and improving the ease of use of the dispersion component 3.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a base 8 is provided at the bottom of the tank body 1, and a steering wheel 9 is fixedly connected to each of the four corners of the bottom of the base 8.

[0039] Specifically, such as Figure 2 , Figure 3 As shown, a support plate 10 is movably connected to the top of the base 8. The top of the support plate 10 is fixedly connected to the bottom of the tank 1, and several buffers 11 are fixedly connected to the bottom of the support plate 10.

[0040] In this embodiment: the base 8 can be moved smoothly by the steering wheel 9, and the position of the device can be adjusted according to the actual situation. At the same time, under the action of the buffer 11, it generates a reaction force, which drives the support plate 10 to return to its original position smoothly. This can buffer the impact force from the outside, ensure the stability of the device during the processing, and improve the stability of the device.

[0041] Working Principle: During the pouring of the ECC bridge deck, the base 8 can be moved smoothly by the steering wheel 9, allowing the device's position to be adjusted according to actual conditions. Simultaneously, the buffer 11 generates a reaction force, causing the support plate 10 to smoothly return to its original position, buffering external impacts and ensuring the device's stability during processing. Then, the top cover 304 allows fibers to enter the inlet pipe 301 and seals it, preventing fibers from scattering in the outside air. The combination of the suction pipe 6 and louvers 7 increases the suction range and filters impurities from the outside air. Simultaneously, the pressurized fan 306 allows the filtered air to flow smoothly into the inlet pipe 301 through the air supply pipe 307, thereby carrying... The smooth flow of the moving fibers protects the pressurizing blower 306 and reduces the probability of its failure. Then, the grinding roller 302 is driven to rotate smoothly by the rotating motor 303, which can break up the fiber clumps. At the same time, under the action of the inlet valve 305, the broken fibers can be smoothly blown into the interior of the tank 1, ensuring the quality of the ECC bridge deck casting. Then, the rotating rod 202 is driven to rotate by the mixing motor 201, which drives the connecting plate 205 and the cross fixing plate 203 to rotate, and simultaneously drives the stirring blade 204 to rotate, which can drive the raw materials and fibers inside the tank 1 to flow, thereby ensuring the full mixing of the raw materials and fibers. Then, under the action of the scraper 206, the scraper 206 moves along the inner wall of the tank 1, which can scrape off the material attached to the inner wall of the tank 1, avoiding the accumulation of material residues that may interfere with the subsequent mixing process.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
