Description

Technical Field

[0001] This utility model relates to the field of fixed building technology, and in particular to an asphalt manufacturing device with a cleaning structure. Background Technology

[0002] In the asphalt manufacturing process, the mixing tank plays a crucial role. The cleaning scraper inside the tank is like a broom for cleaning at home, responsible for cleaning the asphalt residue on the tank wall. This ensures that the mixing tank is clean and tidy, so that it will not affect the next asphalt production. However, this "broom", that is, the cleaning scraper, now has many troublesome problems.

[0003] Most cleaning scrapers are made of a single piece of metal or ordinary materials. Take a broom for sweeping the floor at home as an example. If the broom is used for a long time and the bristles are worn out, it will not sweep the floor clean and you will have to replace it with a new broom, which will increase the cost. Similarly, in the asphalt manufacturing industry, traditional cleaning scrapers wear out very quickly when faced with high temperature and high viscosity asphalt.

[0004] During asphalt manufacturing, the temperature inside the mixing tank is extremely high, and the asphalt is very sticky, like melted syrup stuck to the tank walls. When the scraper scrapes this asphalt, it has to withstand a lot of friction. In addition, there may be some small particles and impurities in the asphalt, which is like sweeping the ground with many small stones. Of course, the broom will wear out quickly. Once the scraper wears out, the cleaning effect will be greatly reduced, and a lot of asphalt will remain on the tank walls. If this residual asphalt is not cleaned properly, it will affect the quality of the new asphalt in the next batch of asphalt manufacturing and may also cause uneven mixing, just like having lumps in the dough when kneading it, resulting in a poor texture in the finished product. This, in turn, reduces the lifespan of the scraper. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an asphalt manufacturing device with a cleaning structure. This device can solve the problem that when the scraper scrapes the asphalt, it has to withstand a lot of friction. In addition, there may be some small particles and impurities in the asphalt. This is like sweeping the ground with a broom and finding many small stones. The broom will wear out quickly. Once the scraper is worn, the cleaning effect will be greatly reduced. A lot of asphalt will remain on the tank wall. If this residual asphalt is not cleaned properly, it will affect the quality of the new asphalt when manufacturing asphalt next time. It may also cause uneven mixing, just like having lumps in the dough when kneading it. This will result in a poor texture of the finished product and reduce the service life of the scraper.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an asphalt manufacturing device with a cleaning structure, including a mixing tank 1, a control panel 2, a tank cover 3, a motor 4, a feed pipe 5, a discharge pipe 6, and a mixing shaft 8; The stirring shaft 8 is equipped with a wear-resistant liner protection assembly; The wear-resistant liner protection assembly includes a fixing frame 15, two wear-resistant liner sleeves 9, and two scrapers 12. The fixing frame 15 is fixedly installed on the outer wall of the stirring shaft 8, which is rotatably installed on the lower surface of the tank cover 3. Multiple butterfly spring assemblies 14 are installed inside grooves on both sides of the outer wall of the fixing frame 15. One end of the outer wall of each scraper 12 is slidably connected to the corresponding groove on both sides of the outer wall of the fixing frame 15. The outer walls of the multiple butterfly spring assemblies 14 away from the fixing frame 15 are respectively fixedly connected to the outer wall of the corresponding scraper 12 closest to the fixing frame 15. Each wear-resistant liner sleeve 9 is slidably fitted onto the outer wall of the scraper 12. The outer walls of both scrapers 12 are provided with twelve fixing bolt slots 13. The twelve fixing bolt slots 13 on the scraper 12 are in groups of four. The outer walls of the two wear-resistant liner sleeves 9 are fixedly installed with six fixing plates 10. The six fixing plates 10 on the wear-resistant liner sleeves 9 are in groups of two. The outer walls of the three groups of fixing plates 10 are threaded with two fixing bolts 11. The two wear-resistant liner sleeves 9 are installed on the scraper 12 through the fixing plates 10 and the corresponding fixing bolt slots 13 on the scraper 12.

[0024] The motor 4 is fixedly installed on the upper surface of the tank cover 3, which is bolted to the upper outer wall of the mixing tank 1. The feed pipe 5 is fixedly installed on the upper surface of the tank cover 3, and the interior of the mixing tank 1 is connected to the interior of the feed pipe 5. The output end of the motor 4 extends to the outside of the tank cover 3 and is fixedly connected to one end of the stirring shaft 8. The control panel 2 is fixedly installed on the upper outer wall of the mixing tank 1, and the motor 4 is electrically connected to the control panel 2. The discharge pipe 6 is fixedly installed at the lower end of the mixing tank 1, and the interior of the mixing tank 1 is connected to the interior of the discharge pipe 6. A heating pipe 7 is installed inside the mixing tank 1, and the heating pipe 7 is arranged in a spiral shape. The control panel 2 is electrically connected to the heating pipe 7.

[0025] Furthermore, when using this device, the heating pipe 7 is first activated via the control panel 2 to preheat the interior of the mixing tank 1. After reaching a suitable temperature, the asphalt raw material is conveyed into the mixing tank 1 through the feed pipe 5. Then, the motor 4 is activated via the control panel 2. The output end of the motor 4 drives the mixing shaft 8 to rotate. The rotation of the mixing shaft 8 drives the fixed frame 15 to rotate as well. The fixed frame 15 drives the scraper 12 to rotate via the butterfly spring assembly 14. During the rotation of the scraper 12, due to the elastic force of the butterfly spring assembly 14, the scraper 12 is tightly attached to the inner wall of the mixing tank 1. The wear-resistant lining sleeve 9, which is sleeved on the outer wall of the scraper 12, rotates with the scraper 12 to scrape off the asphalt adhering to the tank wall, preventing asphalt from accumulating on the tank wall. The wear-resistant lining sleeve 9 is fixed to the scraper 12 via the fixed plate 10 and the fixed bolt 11. The fixed bolt slot 13 is used for fixing, ensuring that it will not loosen during the scraping process. At the same time, the wear-resistant material reduces the wear of the scraper 12. When it is necessary to clean or replace the wear-resistant liner 9, simply unscrew the fixing bolt 11, slide the wear-resistant liner 9 off the scraper 12, replace it with a new wear-resistant liner 9, and then fix it with the fixing bolt 11. The operation is convenient. During the mixing process, the heating pipe 7 continuously heats the asphalt, keeping it in good fluidity and facilitating thorough mixing. After mixing is completed, the motor 4 and the heating pipe 7 are turned off, and the mixed asphalt is discharged from the mixing tank 1 through the discharge pipe 6. If there is still residual asphalt on the tank wall, the motor 4 can be restarted to allow the scraper 12 and the wear-resistant liner 9 to continue working and cleaning the tank wall. The entire process is conveniently controlled through the control panel 2, ensuring efficient asphalt production and tank wall cleaning.

[0026] The wear-resistant liner sleeve 9 in the wear-resistant liner protection assembly can be detached and installed by cooperating with the fixing plate 10, fixing bolt 11 and fixing bolt groove 13 on the scraper 12. When the wear-resistant liner sleeve 9 is worn due to long-term scraping of high temperature and viscous asphalt, it is not necessary to replace the entire scraper 12. Just unscrew the fixing bolt 11, remove the old wear-resistant liner sleeve 9 and replace it with a new one. This "partial replacement" mode greatly reduces the cost of spare parts and reduces resource waste.
