Description

Technical Field

[0001] The utility model relates to a blower for an aluminum melting furnace, in particular to an installation structure thereof in a factory building. Background Art

[0002] In the prior art, an aluminum melting furnace is placed on the ground of a factory building, and a blower is arranged beside the aluminum melting furnace. The blower and the aluminum melting furnace are arranged side by side face to face. The blower is as close as possible to the aluminum melting furnace in the transverse direction to make the structure compact. An air duct extends from the side wall of the blower facing the aluminum melting furnace, and the distal end of the air duct is connected to the side wall of the aluminum melting furnace facing the blower. The blower is too close to the aluminum melting furnace in the transverse direction. Although the structure is compact, there are the following two problems: on the one hand, the space between the blower and the aluminum melting furnace is narrow, and there is an air duct blocking, which makes it inconvenient to repair the side wall of the aluminum melting furnace facing the blower; on the other hand, the blower generates noise. If the blower is too close to the aluminum melting furnace, the noise near the aluminum melting furnace will be too loud, causing hearing damage to the operators beside the aluminum melting furnace. Content of the Utility Model

[0003] The utility model aims to provide an installation structure of a blower for an aluminum melting furnace, which can reserve the maintenance space at the side wall of the aluminum melting furnace facing the blower and avoid the hearing damage caused by the noise generated by the blower to the operators beside the aluminum melting furnace on the premise of ensuring the compact structure of the blower and the aluminum melting furnace in the transverse direction.

[0004] An installation structure of a blower for an aluminum melting furnace includes a factory building ground, and an aluminum melting furnace is placed on the factory building ground; a blower is arranged on the left side of the aluminum melting furnace, an air duct extends from the right side wall of the blower, and the right end of the air duct is connected to the left side wall of the aluminum melting furnace. The underground layer below the factory building ground includes an underground soil layer, and a maintenance well is opened on the left side of the local part directly below the aluminum melting furnace in the underground soil layer. The blower is accommodated in the right part of the maintenance well close to the aluminum melting furnace. A wellhead is opened on the local part of the factory building ground directly above the left part of the maintenance well, a manhole cover is installed on the wellhead, and a ventilation opening is opened on the manhole cover, and a sound-absorbing cotton board is installed in the ventilation opening.

[0005] Further, the manhole cover has three layers, which are an upper wire mesh, a middle sound-absorbing cotton board and a lower wire mesh from top to bottom. The mesh holes of the upper wire mesh and the lower wire mesh serve as the ventilation opening.

[0006] Further, a supporting frame is installed at the wellhead, and the supporting frame supports the peripheral edge of the bottom wall of the manhole cover; a positioning frame is installed at the non-peripheral part of the bottom wall of the manhole cover. When the manhole cover is in the state of closing the wellhead, the positioning frame falls into the supporting frame and is limited by the circumferential inner wall of the supporting frame.

[0007] Further, a sound-absorbing buffer pad is installed on the circumferential outer wall of the positioning frame.

[0008] The beneficial effects are as follows: In the present utility model, the blower is placed as close as possible to the molten aluminum furnace in the horizontal position, ensuring a compact structure. On this basis, due to the different height positions from the molten aluminum furnace, a maintenance space is reserved at the left side wall of the molten aluminum furnace, facilitating the maintenance of the left side wall of the molten aluminum furnace. The blower is placed in the maintenance well. When the blower is working, the well cover closes the wellhead of the maintenance well, and the noise generated by the blower is blocked by the sound-absorbing cotton board on the well cover. Therefore, the decibel value reaching the molten aluminum furnace has been greatly reduced, avoiding hearing damage to the operators beside the molten aluminum furnace.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following further elaborates on the present inventive concept in conjunction with the specific embodiments.

[0014] As Figure 1 shown, the factory floor includes a left part and a right part. A molten aluminum furnace 1 is placed on the right part 17 of the factory floor. The underground soil layer 2 directly below the left part 16 of the factory floor is hollowed out to form a maintenance well 13. The right part of the maintenance well 13 is close to the molten aluminum furnace 1, and a blower 3 is placed in the right part of the maintenance well 13. An air duct 15 is installed on the right side wall of the blower 3. The right end of the air duct 15 extends upward through the right part 17 of the factory floor and then turns right to connect to the left side wall of the molten aluminum furnace 1 and then communicates with the inner cavity of the molten aluminum furnace 1. A wellhead 12 is provided in a local area of the left part 16 of the factory floor directly above the left part of the maintenance well 13. A well cover 7 is provided at the wellhead 12, and the right end of the well cover 7 is hinged to the left end of the right part 17 of the factory floor. As Figure 2As shown, the manhole cover 7 has three layers, which are the upper wire mesh 4, the middle sound-absorbing cotton board 5, and the lower wire mesh 6 from top to bottom. The upper wire mesh 4 and the lower wire mesh 6 fix the middle sound-absorbing cotton board 5. The manhole cover 7 closes the wellhead 12, and the middle sound-absorbing cotton board 5 of the manhole cover 7 insulates the wellhead 12 of the inspection well 13. The mesh holes of the upper wire mesh 4 and the lower wire mesh 6 serve as ventilation openings, and the blower 3 sucks air from outside the wellhead 12 of the inspection well 13 through the mesh holes and blows air into the inner cavity of the aluminum melting furnace 1. A supporting frame 9 is installed on the inner side wall of the right part 17 of the factory floor at the wellhead 12, and the supporting frame 9 supports the peripheral edge 14 of the bottom wall of the manhole cover 7; a positioning frame 10 is installed at a non-peripheral position on the bottom wall of the manhole cover 7, and the positioning frame 10 sinks into the supporting frame 9 and is limited by the circumferential inner wall of the supporting frame 9. A sound-absorbing buffer pad 11 is installed on the circumferential outer wall of the positioning frame 10, and the sound-absorbing buffer pad 11 closes the gap between the circumferential outer wall of the positioning frame 10 and the circumferential inner wall of the supporting frame 9, having both buffering and sound-absorbing functions.

[0015] When the blower 3 needs to be overhauled, the operator rotates the manhole cover 7 around the hinge 8 to Figure 3 a state, and the operator can enter the inspection well 13 to overhaul the blower 3. The blower 3 is as close as possible to the aluminum melting furnace 1 in the horizontal position, ensuring a compact structure. On this basis, since the height position of the blower 3 is different from that of the aluminum melting furnace 1, a maintenance space is reserved at the left side wall of the aluminum melting furnace 1, facilitating the maintenance of the left side wall of the aluminum melting furnace 1.

[0016] As described above, it is only the implementation mode of the present utility model creation, and does not limit the scope of patent protection. Those skilled in the art make non-substantive changes or substitutions based on the present utility model creation, and still fall within the scope of patent protection.
