Because the impeller used in this fan is a multi-blade fan, the working principle is the same as that of the centrifugal fan, so it is very popular and vividly called a multi-blade centrifugal fan. The aging furnace uses a double-intake multi-blade centrifugal fan.

[0003] An existing single-inlet multi-blade centrifugal fan for an aging furnace can refer to the utility model patent with Chinese patent announcement number CN220850166U, which discloses a single-inlet multi-blade centrifugal fan for an aging furnace, and relates to the technical field of aluminum aging furnace fans. It improves the problem that external dust can easily enter the inside of the fan, and it is time-consuming and labor-intensive to disassemble the fan for cleaning. The fan comprises a base, the base is fixedly connected to a casing, a long shaft is rotatably connected to the side wall of the casing through a bearing, an impeller is fixedly sleeved on the long shaft, an air inlet and an air outlet are opened on the casing, a mounting mechanism is arranged on the casing, a dustproof net is arranged on the air inlet, and a power mechanism is arranged on the base.

[0004] However, during the actual use of the device, it was found that although the device can improve the dust-proof effect through the dust-proof net, the device uses mounting bolts to fix the dust-proof net. This results in the need to use special equipment to disassemble the device after long-term use, which increases its maintenance difficulty. Therefore, the present application provides a double-intake multi-blade centrifugal fan for an aging furnace to meet the demand. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a double-intake multi-wing centrifugal fan for an aging furnace to solve the problem that the dust screen of the existing device is fixed by mounting bolts, which leads to the need to use special equipment to disassemble the device after long-term use, thereby increasing the difficulty of maintenance.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A double-intake multi-blade centrifugal fan for an aging furnace comprises: a base, and a double-intake multi-blade centrifugal fan body and a dustproof component installed on the top of the base; the dustproof component comprises a fixed ring installed on the outer wall of the double-intake multi-blade centrifugal fan body, the inner wall of the fixed ring is provided with a circular groove, the top of the inner wall of the circular groove is fixedly equipped with a spring, the bottom of the spring is fixedly equipped with a connecting block, the bottom of the connecting block is fixedly equipped with a clamping block, the outer wall of the clamping block is clamped with a dustproof plate, the outer wall of the fixed ring is provided with an annular groove, the inner wall of the annular groove is rotatably connected with a swivel, the end of the connecting block away from the clamping block is fixedly equipped with a connecting rope, and the end of the connecting rope away from the connecting block is fixedly connected to the swivel.

[0008] A groove is provided at the bottom of the base, and a rubber pad is fixedly mounted on the inner wall of the groove.

[0009] A clamping groove is formed on the outer wall of the dustproof plate, and a limiting block is clamped on the inner wall of the clamping groove. The side of the limiting block away from the clamping groove is fixedly connected to the inner wall of the fixing ring.

[0010] The limiting block is inclined toward the dustproof plate at a side away from the double-intake multi-blade centrifugal fan body.

[0011] The cross-sectional shape of the block is a right-angled trapezoid, and the hypotenuse of the block is located at a side away from the double-intake multi-blade centrifugal fan body.

[0012] The number of the springs, connecting blocks and clamping blocks is six, and the six springs, connecting blocks and clamping blocks are evenly distributed on the circumference of the inner wall of the fixing ring.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, when the dustproof plate needs to be disassembled, the connecting rope is displaced by rotating the swivel, thereby pulling the connecting block and the clamping block to separate from the dustproof plate. At this time, the dustproof plate can be disassembled. When the dustproof plate needs to be installed, the dustproof plate only needs to be aligned with the inner wall of the fixing ring and inserted inward. When the clamping block is squeezed, it moves toward the depth of the circular groove until the dustproof plate is completely inserted into the fixing ring. At this time, the clamping block is no longer squeezed, and the connecting block and the clamping block are pushed toward the direction of the dustproof plate by the spring until they are clamped with the dustproof plate, thereby completing the installation of the dustproof plate, which is conducive to improving the convenience of disassembly and assembly of the dustproof plate and ensuring the protection effect against dust.

[0015] 2. In the above scheme, by providing the grooves and the rubber pads, it is helpful to increase the friction between the bottom of the device and the contact surface, thereby improving the stability of the device during use. At the same time, the rubber also has a certain shock-absorbing effect, thereby reducing the noise generated during its use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the utility model provides a double-intake multi-blade centrifugal fan for an aging furnace, comprising: a base 1, and a double-intake multi-blade centrifugal fan body 2 and a dust-proof component 3 installed on the top of the base 1; the dust-proof component 3 comprises a fixing ring 31 installed on the outer wall of the double-intake multi-blade centrifugal fan body 2, the inner wall of the fixing ring 31 is provided with a circular groove 32, the top of the inner wall of the circular groove 32 is fixedly equipped with a spring 33 providing elastic force, the bottom of the spring 33 is fixedly equipped with a connecting block 34, the bottom of the connecting block 34 is fixedly equipped with a clamping block 35, and the outer wall of the clamping block 35 is clamped with a spring 33 for removing dust. The dustproof plate 36 of the filter has an annular groove 37 on the outer wall of the fixing ring 31, and the inner wall of the annular groove 37 is rotatably connected with a swivel 38. The end of the connecting block 34 away from the clamping block 35 is fixedly equipped with a connecting rope 39, and the end of the connecting rope 39 away from the connecting block 34 is fixedly connected to the swivel 38. The number of springs 33, connecting blocks 34 and clamping blocks 35 is six, and the six springs 33, connecting blocks 34 and clamping blocks 35 are evenly distributed on the circumferential side of the inner wall of the fixing ring 31. By limiting the number and position of the springs 33, connecting blocks 34 and clamping blocks 35, it is beneficial to ensure the firmness of the dustproof plate 36 when it is fixed.

[0032] like Figure 1 and Figure 2 As shown, a groove 11 is provided at the bottom of the base 1, and a rubber pad 12 is fixedly mounted on the inner wall of the groove 11. The groove 11 and the rubber pad 12 are provided to increase the friction between the bottom of the device and the contact surface, thereby improving the stability of the device during use. At the same time, the rubber also has a certain shock-absorbing effect, thereby reducing the noise generated during use.

[0033] like Figure 2 and Figure 3 As shown, a slot 4 is provided on the outer wall of the dustproof plate 36, and a limiting block 5 is clamped on the inner wall of the slot 4. The side of the limiting block 5 away from the slot 4 is fixedly connected to the inner wall of the fixing ring 31. By setting the slot 4 and the limiting block 5, it is helpful to limit the installation of the dustproof plate 36 and improve the stability of the fixation of the dustproof plate 36.

[0034] like Figure 2 and Figure 3 As shown, the limit block 5 is inclined toward the dustproof plate 36 away from the side of the double-intake multi-blade centrifugal fan body 2. By limiting the limit block 5, it is beneficial to guide the dustproof plate 36 when installing the dustproof plate 36, thereby improving the convenience of its installation.

[0035] like Figure 2 and Figure 3 As shown, the cross-sectional shape of the block 35 is a right-angled trapezoid, and the hypotenuse of the block 35 is located on the side away from the double-intake multi-blade centrifugal fan body 2. By limiting the block 35, it is helpful to improve the smoothness of the installation of the dust plate 36.

[0036] The technical solution provided by the utility model is that when the dustproof plate 36 needs to be disassembled during operation, the swivel ring 38 is rotated to drive the connecting rope 39 to move, thereby pulling the connecting block 34 and the clamping block 35 to separate from the dustproof plate 36, and the dustproof plate 36 can be disassembled at this time. When the dustproof plate 36 needs to be installed, it is only necessary to align the dustproof plate 36 with the inner wall of the fixing ring 31 and insert it inwardly. When the clamping block 35 is squeezed, it moves to the depth of the circular groove 32 until the dustproof plate 36 is completely inserted into the fixing ring 31. At this time, the clamping block 35 lacks squeezing, and the spring 33 pushes the connecting block 34 and the clamping block 35 in the direction of the dustproof plate 36 until they are clamped with the dustproof plate 36, thereby completing the installation of the dustproof plate 36.

[0037] The groove 11 and the rubber pad 12 are provided to increase the friction between the bottom of the device and the contact surface, thereby improving the stability of the device when in use. At the same time, the rubber also has a certain shock-absorbing effect, thereby reducing the noise generated when in use.
