Description

Technical Field

[0001] This utility model relates to the field of high-temperature calcining furnace technology, and in particular to a high-temperature calcining furnace for recycling recycled metals. Background Technology

[0002] The main function of a high-temperature calcining furnace is to heat raw materials, promote chemical reactions, and improve the performance of raw materials. During the high-temperature calcination process, the raw material particles undergo internal and external decomposition and recombination to form new crystal structures and compounds, thereby improving the physical properties of the raw materials, such as increasing hardness, wear resistance, and impermeability, to meet the production needs of specific industries.

[0003] During the high-temperature calcination process, harmful substances in the recycled metal decompose into harmful gases. These harmful gases need to be discharged through exhaust pipes to prevent them from harming the health of workers. During the exhaust process, because the gases contain a large number of calcined particulate impurities, they need to be filtered to facilitate the subsequent centralized treatment and absorption of harmful gases. After these particulate impurities are filtered through the filter screen, some of them will accumulate on the surface of the filter screen and need to be cleaned regularly. However, after these particulate impurities harden, they are very difficult to clean. Utility Model Content

[0004] To overcome the problem that after particulate impurities pass through the filter screen, some of them accumulate on the surface of the filter screen and need to be cleaned regularly, but these particulate impurities are very troublesome to clean after they harden.

[0008] Preferably, a collection pipe is fixedly connected to the surface of the exhaust pipe, and a filter cover is fixedly installed at the lower end of the collection pipe. The filter cover is used to filter out particulate impurities that have been cleaned up, and a secondary exhaust fan is located at the upper end of the collection pipe.

[0009] Preferably, a bearing seat is fixedly installed on the inner wall of the calcining furnace body, the stirring rod is rotatably connected to the end of the stirring rod, a motor is fixedly installed on one side of the calcining furnace body, a connecting shaft three is fixedly connected to one end of the motor, a bevel gear three is fixedly connected to one end of the connecting shaft three, a bevel gear four is fixedly connected to one end of the stirring rod, and the bevel gear four meshes with the bevel gear three.

[0012] The beneficial effects of this utility model are:

[0013] 1. In the process of the high-temperature calcining furnace for recycling metals, the main induced flow fan introduces harmful gases and particulate impurities generated during calcination into the exhaust pipe, while simultaneously driving the cleaning plate to rotate. The cleaning plate continuously cleans the particulate impurities accumulated on the surface of the filter screen, thereby preventing the particulate impurities from hardening on the surface of the filter screen. When the main induced flow fan is working, it also drives the auxiliary induced flow fan to rotate, and the cleaned impurities are sucked into the collection pipe, thus completing the centralized collection of impurities.

[0014] 2. After calcination, during cooling, the rotating stirring rod disperses the calcination residue, increasing the contact area between the residue and air, thus accelerating cooling. The rotating stirring rod also drives the stirring roller to rotate, which in turn mixes the absorbent liquid in the waste gas purification chamber. This prevents the high temperature of the waste gas from causing excessively high temperatures in some areas of the absorbent liquid, which would otherwise result in ineffective absorption of harmful gases from the waste gas.

The surface of the exhaust pipe 3 has an opening. A mounting bracket 12 is fixedly connected to the opening of the surface of the exhaust pipe 3. A connecting shaft 13 is rotatably connected to the surface of the mounting bracket 12. A secondary exhaust fan 14 is fixedly connected to the lower end of the connecting shaft 13. A bevel gear 15 is fixedly connected to the upper end of the connecting shaft 13. The bevel gear 15 meshes with the bevel gear 8. A protective shell is provided inside the exhaust pipe 3. Both the bevel gear 15 and the bevel gear 8 are located in the protective shell. A collection pipe 16 is fixedly connected to the surface of the exhaust pipe 3. A filter cover 17 is fixedly installed at the lower end of the collection pipe 16. The filter cover 17 is used to filter the particulate impurities that are cleaned up. The auxiliary flow fan 14 is located at the upper end of the collection pipe 16. After calcination, the main flow fan 6 is started. The main flow fan 6 introduces harmful gases and particulate impurities generated during calcination into the exhaust pipe 3. The particulate impurities are filtered by the filter screen 11. The harmful gases in the exhaust gas enter the exhaust gas purification box 4 through the exhaust pipe 3 for absorption. During the rotation of the main flow fan 6, the cleaning plate 10 rotates at the same time. During the rotation of the cleaning plate 10, it will continuously clean the particulate impurities accumulated on the surface of the filter screen 11, thereby preventing the particulate impurities from hardening on the surface of the filter screen 11. The auxiliary flow fan 14 rotates at the same time. Under the action of the auxiliary flow fan 14, the cleaned impurities are sucked into the collection pipe 16. The filter cover 17 at the lower end of the collection pipe 16 filters and collects the impurities. This completes the centralized collection of impurities. The protective shell is used to protect the various connecting parts to ensure that impurities cannot enter them and affect their operation.

[0024] Please see Figure 3 and Figure 4In this embodiment, a bearing seat 18 is fixedly installed on the inner wall of the calcining furnace body 1. A stirring rod 19 is rotatably connected to the end of the stirring rod 19. A motor 20 is fixedly installed on one side of the calcining furnace body 1.

A connecting shaft 25 is rotatably connected inside the calcining furnace body 1. A bevel gear 24 is fixedly connected to one end of the connecting shaft 25. The bevel gear 24 meshes with the bevel gear 23. A protective shell is provided inside the calcining furnace body 1. The bevel gears 22, 23, and 24 are all located in the protective shell. A transmission wheel 26 is fixedly connected to one end of the connecting shaft 25. A stirring roller 27 is rotatably connected inside the exhaust gas purification box 4. One end of the stirring roller 27 is fixedly connected to... There is a second transmission wheel 28, which is connected to the first transmission wheel 26 via a belt. The stirring roller 27 is used to mix the absorbent liquid. Multiple sets of heat sinks 29 are fixedly installed on one side of the exhaust gas purification box 4. After calcination, the calcination residue needs to be cooled before it can be processed. During cooling, the motor 20 is started, and the stirring rod 19 rotates simultaneously at the bearing seat 18. During the rotation of the stirring rod 19, the calcination residue is dispersed, so that the contact area between the calcination residue and the air will be larger, thereby accelerating the cooling. During the rotation of the stirring rod 19, the stirring roller 27 rotates simultaneously. The stirring roller 27 is used to mix the absorbent liquid in the exhaust gas purification box 4 to prevent the temperature of the absorbent liquid in some areas from becoming too high after the high temperature exhaust gas enters the exhaust gas purification box 4 through the exhaust pipe 3. The absorbent liquid with too high a temperature will not have an ideal absorption effect on the harmful gases in the exhaust gas. The heat sink 29 is used to further ensure the heat dissipation of the absorbent liquid in the exhaust gas purification box 4.

[0025] After calcination is completed, the main exhaust fan 6, which is fixedly installed on one side of the mounting bracket 5, is started. The main exhaust fan 6 introduces harmful gases and particulate impurities generated during calcination into the exhaust pipe 3. The particulate impurities are filtered by the filter screen 11 fixedly installed inside the exhaust pipe 3, and the harmful gases in the exhaust gas enter the exhaust gas purification box 4 for absorption through the exhaust pipe 3.

[0026] During the rotation of the main exhaust fan 6, the connecting shaft 7, which is fixedly connected to one end of the main exhaust fan 6 shaft, simultaneously drives the connecting rod 9 to rotate. The cleaning plate 10, which is fixedly connected to one end of the connecting rod 9, also rotates. During the rotation, the cleaning plate 10 continuously cleans the particulate impurities accumulated on the surface of the filter screen 11, thereby preventing the particulate impurities from accumulating and hardening on the surface of the filter screen 11.

[0027] A bevel gear 8 is fixedly connected to the surface of the connecting shaft 7. The bevel gear 8 meshes with the bevel gear 15. The bevel gear 15 is fixedly connected to the upper end of the connecting shaft 13. The connecting shaft 13 rotates at the mounting bracket 12. The auxiliary exhaust fan 14, which is fixedly connected to the lower end of the connecting shaft 13, also rotates. Under the action of the auxiliary exhaust fan 14, the cleaned impurities are sucked into the collection pipe 16. The filter cover 17 at the lower end of the collection pipe 16 filters and collects the impurities, thus completing the centralized collection of impurities.

[0028] After calcination, the calcination residue needs to be cooled before it can be processed. During cooling, the motor 20 is started, and the motor 20 drives the connecting shaft 21 to rotate. The bevel gear 22 at one end of the connecting shaft 21 rotates at the same time, and the bevel gear 23 meshing with the bevel gear 22 rotates at the same time. The bevel gear 23 is fixedly connected to one end of the stirring rod 19. The stirring rod 19 rotates at the bearing seat 18. During the rotation, the stirring rod 19 disperses the calcination residue, so that the contact area between the calcination residue and the air will be larger, thereby accelerating the cooling.

[0029] During the rotation of the stirring rod 19, the bevel gear 24, which meshes with the bevel gear 23, rotates simultaneously. The bevel gear 24 is fixedly connected to one end of the connecting shaft 25. When the connecting shaft 25 rotates, the transmission wheel 26, which is fixedly connected to one end of the connecting shaft 25, simultaneously drives the transmission wheel 28 to rotate. The transmission wheel 28 is fixedly connected to one end of the stirring roller 27. The stirring roller 27 rotates simultaneously. The stirring roller 27 is used to mix the absorbent liquid in the exhaust gas purification box 4 to prevent the temperature of the absorbent liquid in some areas from becoming too high after the high-temperature exhaust gas enters the exhaust gas purification box 4 through the exhaust pipe 3. If the temperature of the absorbent liquid is too high, the absorption effect of the absorbent liquid in the exhaust gas will not be ideal. The heat sink 29 is used to further ensure the heat dissipation of the absorbent liquid in the exhaust gas purification box 4.

[0030] Through the above steps, during the process of the main exhaust fan 6 introducing harmful gases and particulate impurities generated during calcination into the exhaust pipe 3, the high-temperature calcining furnace for recycling recycled metal will simultaneously drive the cleaning plate 10 to rotate. The cleaning plate 10 will continuously clean the particulate impurities accumulated on the surface of the filter screen 11, thereby preventing the particulate impurities from accumulating and hardening on the surface of the filter screen 11. When the main exhaust fan 6 is working, it will simultaneously drive the auxiliary exhaust fan 14 to rotate, and the cleaned impurities will be sucked into the collection pipe 16, thus completing the centralized collection of impurities.
