[0002] In the process of heating and processing aluminum rods, the aluminum rod furnace is an important heating device that generates a large amount of waste heat during operation. If this waste heat cannot be effectively utilized, it will not only waste energy but may also have an adverse impact on the production environment. Therefore, the recovery and utilization of waste heat from aluminum rod furnaces has become an important research direction in this field.
[0003] A prior art energy-saving aluminum rod heating furnace heat recovery device has a flue gas outlet at the top of the furnace, a feed inlet on one side of the furnace, and an air inlet on the side of the furnace near the feed inlet. A first pipe is fixedly connected to one side of the flue gas outlet, and a dust collector is fixedly connected to the side of the first pipe away from the flue gas outlet. The advantages of this invention are: by setting a first filter plate and a second filter plate, the first, second, third, and fourth filter plates perform two filtrations of the flue gas, thus also protecting the fan; a water storage tank reduces the activity of the flue gas, achieving effective filtration; and a handle allows the filter plate or fan frame to be pulled out directly for inspection and cleaning, enabling quick inspection and cleaning.
[0004] However, although the device is equipped with a handle for easy removal of the filter plate for cleaning, in actual use, if the dust on the filter plate is not cleaned in time, especially after the first filter plate has absorbed a large amount of impurities, the filtration efficiency will decrease, the resistance to flue gas passage will increase, and the effect of waste heat recovery will be affected.
[0005] Therefore, it is necessary to provide an aluminum rod furnace with a waste heat recovery device to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] First Embodiment
[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an aluminum rod furnace with a waste heat recovery device provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure. Figure 3 for Figure 1 The diagram shows a front cross-sectional view of the filter box. Figure 4 for Figure 1 The diagram shows a top-view cross-sectional view of the filter box. An aluminum rod furnace with a waste heat recovery device includes: a furnace body 1;
[0029] Heat exchange box 2, which is fixedly installed on the top of the furnace body 1;
[0030] Fan 3, which is fixedly installed at the gas input end of the heat exchange box 2;
[0031] A filter box 4 is fixedly installed at the input end of the fan 3. Two partitions 41 are fixedly installed on both sides of the inner side of the filter box 4. Baffles 42 are fixedly installed at the bottom of the two partitions 41. A feed chute 43 is opened inside both ends of the baffles 42. A filter plate 44 is arranged between the two partitions 41. A drive motor 46 is fixedly installed on one side of the filter box 4. A threaded rod 47 is fixedly installed at the output end of the drive motor 46. A scraper 48 is threadedly connected to the outer side of the threaded rod 47. A collection frame 49 is arranged at the bottom of the baffles 42. A partition plate 40 is fixedly installed on the inner side of the collection frame 49.
[0032] When the scraper 48 moves from left to right, it pushes the impurities to the right, allowing them to enter the inner side of the feed trough 43. The space to the right of the scraper 48 is sealed, which prevents the impurities from flying around and allows them to fall into the collection box 49 by their own gravity.
[0033] When in use, the drive motor 46 can rotate in both directions, thereby driving the threaded rod 47 to rotate in both directions, and then driving the scraper 48 to move back and forth.
[0034] A sealing plate 45 is fixedly installed on the top of the filter plate 44, and the bottom of the sealing plate 45 abuts against the top of the filter box 4.
[0035] The outer side of the baffle 42 is fixedly installed on the inner side of the filter box 4, one side of the scraper 48 is attached to the side of the filter plate 44, and the bottom of the scraper 48 is attached to the top of the baffle 42.
[0036] An air pipe 5 is fixedly installed at the input end of the filter box 4, and the input end of the air pipe 5 is fixedly installed at the output end of the furnace body 1.
[0037] A water outlet pipe 23 is fixedly installed on the top of one side of the heat exchange box 2, a water inlet pipe 21 is fixedly installed on the bottom of the other side of the heat exchange box 2, and an air outlet pipe 22 is fixedly installed on the back of the heat exchange box 2.
[0038] The heat exchange box 2 is equipped with a spiral heat exchange tube. The inlet end of the spiral heat exchange tube is connected to the outlet end of the fan 3, and the outlet end of the spiral heat exchange tube is connected to the outlet pipe 22. When in use, external cold water enters the heat exchange box 2 through the inlet pipe 21 and comes into contact with the spiral heat exchange tube, thereby heating the water. Then, it is discharged through the outlet pipe 23, thus playing the role of recovering and reusing the waste heat of the aluminum rod furnace.
[0039] The working principle of the aluminum rod furnace with waste heat recovery device provided by this utility model is as follows:
[0040] When in use, the fan 3 draws out the flue gas from inside the furnace body 1 and delivers it to the inner side of the filter box 4 through the air pipe 5. Then it is filtered through the filter plate 44 and enters the inside of the fan 3, then enters the inside of the heat exchange box 2, and is then discharged through the air outlet pipe 22.
[0041] After a certain period of time, the drive motor 46 is automatically started, causing the drive motor 46 to drive the threaded rod 47 to rotate, thereby making the threaded rod 47 threadedly connected inside the scraper 48, thus driving the scraper 48 to move. When the scraper moves from left to right, it will scrape off the dust on the filter plate 44, and then drop it into the inner side of the collection frame 49 through the discharge chute 43.
[0042] After one cleaning cycle is completed, the drive motor 46 will reverse during the next cleaning cycle, thereby moving the scraper 48 from the right to the left to scrape off the impurities on the filter plate 44. At this time, the impurities fall into the inner side of the collection frame 49 through the left feed chute 43.
[0043] Compared with related technologies, the aluminum rod furnace with waste heat recovery device provided by this utility model has the following beneficial effects:
[0044] The filter box 4, partition 41, baffle 42, feed chute 43, filter plate 44, drive motor 46, threaded rod 47, scraper 48, and collection frame 49 work together in a coordinated manner. During use, the drive motor 46 periodically drives the threaded rod 47 to rotate, causing the scraper 48 to move back and forth on the side of the filter plate 44, scraping off the dust on the filter plate 44. The dust falls into the collection frame 49 through the feed chute 43. In this way, there is no need for frequent manual cleaning of the filter plate 44. Impurities on the surface of the filter plate 44 can be automatically removed, effectively preventing the filter plate 44 from reducing filtration efficiency and increasing flue gas resistance due to dust accumulation, thus ensuring the effect of waste heat recovery.

[0048] One end of each of the two corrugated sleeves 6 is fixedly installed on the inner side of the furnace body 1.
[0049] The working principle of the aluminum rod furnace with waste heat recovery device provided by this utility model is as follows:
[0050] When in use, the scraper 48 moves back and forth, which drives the two corrugated sleeves 6 to extend and retract, so that the corrugated sleeves 6 are always fitted on the outer side of the threaded rod 47.
[0051] Compared with related technologies, the aluminum rod furnace with waste heat recovery device provided by this utility model has the following beneficial effects:
[0052] The corrugated sleeve 6 protects the threaded rod 47 during use, preventing dust from accumulating on it and increasing the stability of the scraper 48 during movement.
