Description

Technical Field

[0001] The utility model belongs to the field of waste heat utilization treatment of metal castings, and particularly relates to a waste heat utilization treatment device for metal castings. Background Art

[0002] The heat treatment of metal fasteners is a process of heating metal or alloy workpieces in a certain medium to an appropriate temperature, maintaining them at this temperature for a certain period of time, and then cooling them at different speeds in different media. By changing the microscopic structure on the surface or inside of the metal material, its performance is controlled. The metal heat treatment process can generally be divided into three categories: overall heat treatment, surface heat treatment, and chemical heat treatment. After heat treatment, tempering is required to strengthen the quality of the metal steel strip. A large amount of waste heat will be generated during tempering, so a waste heat recovery device is essential.

[0003] Some treatment devices for waste heat utilization of metal castings have been specially developed in the prior art. For example, the Chinese patent with the publication number "CN214193361U" discloses "a waste heat recovery device for heat treatment of metal fasteners". By setting a magnet, the recovered waste heat is sucked into the interior of the adsorption box, and the metal impurities in the waste heat are adsorbed by the magnet. After adsorption, the waste heat passes through a heat conversion plate for reuse, improving the accuracy of metal fasteners. By setting an annular magnetic strip, the metal impurities can be adsorbed twice, which is beneficial to the accuracy of metal fasteners. Rotating the dust collection sleeve can clean the metal impurities adsorbed inside the dust collection sleeve.

[0004] Although the impurities remaining in the waste heat can be removed by the magnet, it can be found in actual use that the impurities adsorbed on the magnet are difficult to be cleaned by the staff. After long-term use, the surface of the magnet is covered with impurities, which will affect the adsorption effect of the magnet on the impurities. The staff needs to remove the magnet for cleaning, and the impurities adsorbed on the magnet will increase the cleaning difficulty during cleaning, and the impurities on the magnet cannot be quickly cleaned, resulting in the slow operation of the machine and the inability to improve the recovery efficiency.

[0031] Principle of use and advantages: During use, the staff starts the suction pump 9 to absorb the waste heat emitted from the tempering box 4 into the first pipeline 3 from the suction hood 2. Since a connecting pipe 30 is fixedly installed inside the suction hood 2, and three suction ports 28 are fixedly installed at one end of the connecting pipe 30, and the first pipeline 3 is communicated with the connecting pipe 30, the waste heat will flow into the first pipeline 3 from the suction ports 28. Then, under the suction of the suction pump 9, the waste heat will flow through the first pipeline 3 into the filter box 7. A filter net 20 is slidably installed inside the filter box 7. When the waste heat passes through the filter net 20, the impurities in the waste heat will be filtered out by the filter net 20, so that the impurities remaining in the waste heat can be effectively blocked. Since the filter net 20 is slidably installed inside the filter box 7, after long-term use, the filter net 20 needs to be replaced. At this time, pulling the pull rod 6 can take out the filter net 20, which is convenient for replacement and can effectively improve the replacement speed, thereby improving the efficiency of the machine in recovering waste heat. A cover plate 5 is slidably installed on one side of the filter box 7. A sealing gasket 19 and a sealing plate 21 are fixedly installed inside the cover plate 5. A groove 22 is opened inside one side of the filter box 7 close to the cover plate 5. When the cover plate 5 is slidably installed on one side of the filter box 7, the sealing gasket 19 seals inside the filter box 7, and the sealing plate 21 slides into the groove 22, so that the filter box 7 can be effectively sealed to prevent the waste heat from leaking out. After passing through the filter box 7, the waste heat will flow along the second pipeline 17 into the treatment box 16. An activated carbon bucket 36 is movably installed inside the treatment box 16. The filtered waste heat will be secondarily filtered inside the activated carbon bucket 36. The larger impurities remaining in the waste heat inside the filter box 7 before will be removed, and the small amount of harmful stains remaining in the waste heat will be adsorbed by the activated carbon bucket 36, so that the cleanliness of the waste heat can be effectively improved and the harmful stains can be reduced. A circular sealing cover 15 is threadedly connected to the upper end of the treatment box 16. Fixed blocks 34 are fixedly installed inside both the circular sealing cover 15 and the treatment box 16. A circular block 35 is fixedly installed at one end of the fixed block 34 away from the circular sealing cover 15 and the treatment box 16. A circular opening 37 is provided inside the activated carbon bucket 36. When installing the activated carbon inside the treatment box 16, the circular opening 37 needs to be aligned with the circular block 35 for installation, and the circular block 35 at the bottom of the circular sealing cover 15 is also installed inside the circular opening 37, so that the activated carbon bucket 36 can be effectively stabilized inside the treatment box 16, which can effectively improve the filtering effect of the activated carbon bucket 36 and is helpful for replacement and convenient for improving the replacement speed when the activated carbon bucket 36 needs to be replaced. Then, the waste heat filtered by the activated carbon bucket 36 will flow into the third pipeline 14, enter the suction box 8 through the third pipeline, and will flow into the fourth pipeline 11 when passing through the suction box 8. The waste heat inside the fourth pipeline 11 will flow into the recovery box 12.The heat conversion plate 40 installed inside the recycling bin 12 can convert and reuse the waste heat, preventing excessive metal impurities from adhering to the surface of the metal casting, thus affecting the surface finish of the metal fastener and improving the precision of the metal casting. A square sealing cover 13 is threadedly connected to the upper end of the processing box 16 to prevent the waste heat from escaping. Since a plurality of fixing frames 39 are fixedly installed inside both the square sealing plate 21 and the recycling bin 12, when the heat conversion plate 40 needs to be replaced, the square sealing plate 21 can be opened and then the heat conversion plate 40 can be taken out, which can improve the convenience of replacement, improve the efficiency of the machine while facilitating replacement, and finally discharge the filtered waste heat through the air outlet pipe 38 fixedly installed on one side of the recycling bin 12.
