Description

Technical Field

[0001] This utility model relates to the field of aluminum melting furnace technology, specifically to an exhaust device for an aluminum melting furnace. Background Technology

[0002] An aluminum melting furnace is a new type of high-efficiency and energy-saving equipment developed based on the aluminum smelting process, mainly used for melting and holding aluminum ingots. The exhaust system on the aluminum melting furnace primarily functions to collect and discharge waste gases. These waste gases include harmful gases and particulate matter generated during the aluminum smelting process, which are safely guided to the external environment through the exhaust system.

[0003] Utility model patent application document with announcement number "CN212058265U" discloses an exhaust device for an aluminum melting furnace, including a gas pipe, a threaded connecting pipe, a rubber gasket, oil-absorbing cotton, activated carbon filter cotton, and a stainless steel dustproof mesh. This utility model has a simple structure, easily absorbs oil mixed in with the gas, preventing it from adhering to the inside of the pipe wall. Simultaneously, the activated carbon filtration effectively absorbs odors from the gas, facilitating gas filtration and thus effectively cooling the gas. It is easy to operate and suitable for widespread promotion and use.

[0004] The exhaust device for aluminum melting furnace disclosed in the aforementioned document has the following defects: the exhaust device draws gas from inside the aluminum melting furnace into a threaded connecting pipe through an air pump. The gas is filtered by oil-absorbing cotton installed on the inner wall of the threaded connecting pipe and activated carbon filter cotton installed at the bottom of the gas pipe. The filtered gas then enters the gas pipe. If the oil-absorbing cotton and activated carbon filter cotton, which have absorbed oil and odors, cannot be effectively cleaned or replaced after filtration, the filtration effect of the exhaust device for aluminum melting furnace will be reduced, thereby causing environmental pollution.

[0005] Therefore, it can be seen that the existing exhaust devices for aluminum melting furnaces do not provide a convenient and quick way to replace oil-absorbing cotton with activated carbon filter cotton. It is necessary to improve the existing shortcomings and provide an exhaust device for aluminum melting furnaces. Utility Model Content

The housing 301 has a second sliding groove 30102, a third sliding groove 30103, and a fourth sliding groove 30104 inside, which are set to be four in total. Furthermore, they are symmetrically arranged, with the first slide groove 30101, the second slide groove 30102 and the third slide groove 30103 cooperating to form the fifth slide groove, and the second slide groove 30102 and the fourth slide groove 30104 cooperating to form the sixth slide groove. The connecting block 13 is slidably connected inside the fifth slide groove, and the blocking block 302 is slidably connected inside the sixth slide groove. The end of the blocking block 302 away from the air pipe 1 has an inclined surface, and a spring 303 is installed on the outer surface of the blocking block 302. The other end of the spring 303 is installed inside the fourth slide groove 30104.

[0031] The ramp formed by connecting block 13 abuts against the ramp formed by blocking block 302;

[0032] By setting up a connecting block 13, a housing 301, a first slide groove 30101, a second slide groove 30102, a third slide groove 30103, a fourth slide groove 30104, a blocking block 302, and a spring 303, the threaded connecting pipe 2 is installed together with the connecting seat 3 after being squeezed by the blocking block 302 and rotated into the third slide groove 30103 via the connecting block 13.

[0033] The connecting base 3 includes a connector 304. The outer surface of the housing 301 is provided with a seventh sliding groove. There are four seventh sliding grooves arranged symmetrically. One end of the connector 304 is installed on the outer surface of the blocking block 302 through the seventh sliding groove. The other end of the connector 304 is installed with a column 305.

[0034] The connecting base 3 includes a rotating member 306. The housing 301 has an annular groove inside. There are two annular grooves arranged symmetrically.

The limiting post 307 is slidably connected inside the limiting groove. A rubber pad 308 is installed at the other end of the limiting post 307.

[0037] By setting the limiting post 307 and the rubber pad 308, the rotation of the rotating part 306 is restricted, thus preventing the separation of the connecting seat 3 from the threaded connecting pipe 2.

[0038] In use, the gas inside the aluminum melting furnace enters the threaded connecting pipe 2 through the air pump 6. The oil-absorbing cotton 4 and activated carbon filter cotton 5 inside the threaded connecting pipe 2 filter the oil and odor in the gas. Then, the air pump 6 sends the filtered gas into the gas pipe 1. When it is necessary to install the oil-absorbing cotton 4 and activated carbon filter cotton 5, the threaded connecting pipe 2, which contains the oil-absorbing cotton 4 and activated carbon filter cotton 5, is adjusted to a suitable angle so that the connecting block 13 installed on it is aligned with the first slide groove 30101. Then, the connecting block 13 is moved towards the blocking block 302. When the inclined surface of the blocking block 302 is pressed against the inclined surface of the connecting block 13, the blocking block 302 is forced to enter the fourth slide groove 30104 from the second slide groove 30102. At the same time, the connecting block 13 enters the second slide groove 30102 through the first slide groove 30101. Then, by rotating the threaded connecting pipe 2, the connecting block 13 enters the third slide groove 30103. When the connecting block 13 is completely inside the third slide groove 30103... At 0103, the blocking block 302 is pushed by the spring 303 into the second slide groove 30102 and abuts against the outer surface of the connecting block 13, thereby completing the installation of the oil-absorbing cotton 4 and the activated carbon filter cotton 5. When it is necessary to disassemble the oil-absorbing cotton 4 and the activated carbon filter cotton 5, first move the rubber pad 308 away from the housing 301 so that the limiting post 307 releases the rotation restriction on the rotating part 306. Then rotate the rotating part 306 so that the column 305 moves along the ninth slide groove 30601 and drives the blocking block 302 installed at one end of the connecting part 304 to enter the interior of the fourth slide groove 30104 from the second slide groove 30102. Then rotate and lift the threaded connecting pipe 2 so that the connecting block 13 installed on it passes through the second slide groove 30102 from the third slide groove 30103 and through the first slide groove 30101, so that the threaded connecting pipe 2 is separated from the connecting seat 3, thereby smoothly removing the threaded connecting pipe 2 and the oil-absorbing cotton 4 and activated carbon filter cotton 5 inside.
