Description

Technical Field

[0001] This utility model relates to the field of roasting furnace technology, specifically to an adjustable smoke exhaust device for a roasting furnace. Background Technology

[0002] A calcining furnace is an industrial device used to process materials by controlling heating conditions. Calcining furnaces can reduce sintering temperature and improve material properties. They are widely used in metallurgy, chemical industry and new energy fields. Calcining furnaces use exhaust devices to assist in exhausting smoke. There are various types of exhaust devices for calcining furnaces on the market.

[0003] For example, the utility model with authorization announcement number CN212431802U discloses a flue gas exhaust device for a roasting furnace, including a flue gas hood connected to the exhaust end of the roasting furnace. The front surface of the flue gas hood is hinged with a door that can be opened and closed and sealed when closed. The inner surface of the flue gas hood is equipped with a filter body for preliminary filtration. The top of the flue gas hood is equipped with an inlet pipe and an exhaust pipe, and the bottom of the flue gas hood is equipped with an exhaust nozzle for convenient dust discharge. This utility model provides a flue gas hood with a filter body, an inlet pipe, and an exhaust pipe, which performs preliminary filtration near the roasting furnace and cools the flue gas. The externally openable door facilitates maintenance and cleaning. The tapered connecting pipe at the bottom facilitates dust collection, and the screw cap facilitates cleaning and discharge. This effectively solves the problem that when existing roasting furnace flue gas systems use long pipes to transport flue gas to waste gas treatment equipment, dust easily accumulates in the long pipes during transmission, causing poor heat dissipation or even blockage. It is also convenient for cleaning.

[0004] However, based on existing solutions and actual usage, current calcining furnace exhaust devices suffer from insufficient flue gas flow, inconvenient flue gas volume adjustment, insufficient flue gas passage through the filter, poor filtration effect, and inconvenient filter replacement and installation. Therefore, we propose an adjustable exhaust device for calcining furnaces to address the aforementioned problems. Utility Model Content

[0028] 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.

[0029] Please see Figure 1-7This utility model provides a technical solution: an adjustable smoke exhaust device for a roasting furnace, including a smoke inlet pipe 1, a filter barrel 2, a smoke exhaust pipe 3, a partition plate 4, a connecting wheel 5, a limiting ring 6, a fixing rod 7, a first support spring 8, a cover plate 9, mounting bolts 10, a support frame 11, a filter body 12, a mounting frame 13, a lifting ring 14, a second support spring 15, and a mounting block 16;

[0030] First, as attached Figure 1 As shown, a filter barrel 2 is installed at the right end of the smoke inlet pipe 1. An adjustment mechanism for controlling the amount of smoke is provided on the smoke inlet pipe 1. By adjusting the amount of smoke, the smoke enters the filter barrel 2 through the smoke inlet pipe 1. The filter barrel 2 is equipped with a filter mechanism that is easy to disassemble and install to filter the smoke. An exhaust pipe 3 is installed on the lower right side of the filter barrel 2. The filtered smoke is discharged through the exhaust pipe 3.

[0031] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the adjustment mechanism includes a partition 4, a connecting wheel 5, a limiting ring 6, a fixing rod 7, and a first support spring 8. The partition 4 is connected to the smoke inlet pipe 1 by a slot. The partition 4 is rotatably connected to the smoke inlet pipe 1 and adjusts the amount of smoke in the smoke inlet pipe 1. The connecting wheel 5 is fixed above the partition 4. The limiting ring 6 is engaged with the outer side of the connecting wheel 5. When it is necessary to adjust the angle of the partition 4, the limiting ring 6 is slidably connected to the outer side of the fixing rod 7 through the first support spring 8. Pushing the limiting ring 6 downward causes the limiting ring 6 to squeeze the first support spring 8 installed below it. The first support spring 8 is wrapped around the outer side of the fixing rod 7. The fixing rod 7 is slotted in the limiting ring 6 and plays a limiting role for the limiting ring 6. The longitudinal section of the fixing rod 7 has a "T" shaped structure. The fixing rod 7 is symmetrically distributed on the left and right to ensure stability. Pushing the limiting ring 6 causes it to disengage from the engagement connection with the connecting wheel 5. Then the connecting wheel 5 can be rotated. The connecting wheel 5 drives the partition 4 fixed below to rotate. Adjusting the angle of the partition 4 can adjust the amount of smoke inlet.

[0032] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the filtration mechanism includes a support frame 11 and a filter body 12. The filter body 12 is connected to the internal slot of the support frame 11. The support frame 11 is connected to the filter barrel 2. After the flue gas enters the filter barrel 2 from the smoke inlet pipe 1, it is filtered by the filter body 12 and then discharged from the exhaust pipe 3. The lower part of the support frame 11 has a ring structure. The impurities filtered in the filter body 12 will be concentrated at the bottom of the filter barrel 2, which is convenient for cleaning.

[0033] A cover plate 9 is connected to the upper slot of the filter barrel 2. Mounting bolts 10 are installed at equal angles on the outer side of the cover plate 9. When the filter body 12 needs to be replaced, the mounting bolts 10 are removed, allowing the cover plate 9 to be removed from the filter barrel 2, thus detaching it from the slot connection. A mounting bracket 13 is installed on the inner side of the support frame 11. A lifting ring 14 is fixed above the mounting bracket 13, allowing the support frame 11 and filter body 12 to be lifted. The mounting block 16 is slidably connected to the mounting bracket 13 via a second support spring 15. Sliding the mounting block 16, which is connected to the slot on the mounting bracket 13, allows the mounting block 16 to detach from the slot connection. The mounting bracket 13 can be removed from the support frame 11 by compressing the second support spring 15 with the mounting block 16. The filter body 12 can then be removed from the support frame 11. A new filter body 12 can be placed into the support frame 11, so that the filter body 12 and the support frame 11 are connected by the slot. The mounting bracket 13 is placed above the filter body 12. The position of the mounting block 16 is adjusted, the second support spring 15 is compressed, and the mounting block 16 is released. The elasticity of the second support spring 15 pushes the mounting block 16, so that the mounting block 16 and the support frame 11 are connected by the slot. The mounting bracket 13 can then be fixed in the support frame 11.
