TECHNICAL FIELD
[0001] The present application relates to the technical field of fan, in particular to a noise-reducing explosion-proof fan. BACKGROUND
[0002] The fan is a machine that converts mechanical energy into gas pressure energy and kinetic energy, and delivers the gas. The fan is mainly divided into two types of axial flow fan and centrifugal fan. The axial flow fan is widely used in various fields of industrial production due to its simple structure and easy installation. The axial flow fan mainly includes a fan cylinder, a driving motor, an impeller shaft and an impeller connected with the impeller shaft. The fan cylinder is provided with a mounting frame, the driving motor is fixedly installed on the mounting frame, the impeller shaft is rotatably installed on the mounting frame through a rotating shaft, and the output shaft of the driving motor is directly connected with the impeller shaft. During use, the driving motor drives the impeller shaft to rotate, thereby driving the impeller to rotate.
[0003] The Chinese authorized patent document with publication number CN214945164U discloses a low-noise explosion-proof axial flow fan, which includes a shell, a sliding slot is formed in one end of the inner wall of the shell, a mounting ring is slidably arranged in the sliding slot, first and second filter screens are fixedly arranged at the front and rear ends of the mounting ring, a separation screen is fixedly arranged at the tail of the shell, a support is fixedly arranged on the side of the separation screen close to the inside of the shell. The scheme mainly filters dust and foreign matter through the arrangement of the first and second filter screens and the separation screen, avoids foreign matter from entering the inside of the fan to cause the blade to be wound and thus cause the fan to be unable to work normally, and may also cause explosion. The inside of the fan is damped and silenced through the joint action of the soundproof board and the sound-absorbing cotton, the vibration of the motor during work is reduced through the arrangement of the plurality of spring columns, and the wind resistance of the blade during operation is reduced through the arrangement of the plurality of flow guide grooves, thereby achieving the effect of noise reduction and avoiding excessive noise to cause the discomfort of the user.
[0004] The above-mentioned scheme and the axial explosion-proof fan in the prior art generally arrange corresponding sound-absorbing cotton and other sound-absorbing and noise-reducing structures in the inner shell of the cylinder to avoid the generation of large noise during the operation of the fan. However, there is a lack of a noise-reducing component matched with the base of the fan. If the continuous operation power of the fan is too large, although the noise generated inside can be eliminated to a certain extent, the vibration generated by the whole fan will be transmitted to the base, causing the whole fan to shake and also generate corresponding noise. For example, the above-mentioned scheme arranges a shock-absorbing pad on the bottom side of the base, but lacks a matched fixing structure, so that the base still has the possibility of vibrating and causing the position to deviate.

[0018] Compared with the prior art, the present application has the following beneficial effects:
[0019] The explosion-proof fan designed in this invention includes a fan body and connecting flanges at both ends of the fan body. A base is provided on the bottom side of the fan body, and protective filters are connected to both ends of the fan body. Sound-insulating cotton pads are provided on the inner wall of the fan body. A support plate is fixedly installed on the bottom side of the inner cavity of the fan body, and a drive motor is mounted on the support plate, connected to an impeller. A support base plate is fixedly installed at the bottom of the base, and a shock-absorbing pad is fixedly installed at the bottom of the support base plate. The base is stabilized by noise-reducing and stabilizing components. During the operation of the explosion-proof fan, the noise generated inside the fan body is reduced by the sound-insulating cotton pads. For the overall operation of the explosion-proof fan, the base also needs corresponding vibration and noise reduction measures. The support base plate and the shock-absorbing pad at the bottom of the support base plate provide vibration damping for the base of the explosion-proof fan, thus achieving a corresponding noise reduction function.

In this case, this solution uses the second stabilizing component to stabilize the supporting base plate, preventing positional displacement and noise problems caused by vibration.

Detailed Implementation
[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.
[0033] Example 1: Please refer to Figures 1-11A noise-reducing explosion-proof fan includes a fan body 1 and connecting flanges 11 at both ends of the fan body 1. A base 12 is provided on the bottom side of the fan body 1. Protective filters 2 are connected to both ends of the fan body 1. Sound-insulating cotton pads 3 are provided on the inner side wall of the fan body 1. A support plate 4 is fixedly provided on the bottom side of the inner cavity of the fan body 1. A drive motor 5 is provided on the support plate 4 and connected to an impeller 6. A support base plate 7 is fixedly provided at the bottom end of the base 12. A shock-absorbing pad 8 is fixedly provided at the bottom end of the support base plate 7. The base 12 is stabilized by noise-reducing and stabilizing components.
[0034] During the operation of the explosion-proof fan, the noise generated inside the fan casing 1 is reduced by sound-insulating cotton pads 3. For the overall operation of the explosion-proof fan, its base 12 also requires corresponding vibration and noise reduction measures. A support base plate 7 and a shock-absorbing pad 8 are installed at the bottom of the support base plate 7 to provide vibration damping for the base 12, thus achieving noise reduction. Furthermore, this solution also provides stability to the support base plate 7 by setting corresponding noise-reducing stabilizing components, thereby preventing vibration of the base 12 and avoiding positional displacement and noise problems. The noise-reducing stabilizing components include a first stabilizing component and a second stabilizing component, allowing for selection of either the first or second stabilizing component based on actual usage, providing excellent operational flexibility.
[0035] For the placement of the explosion-proof fan, when it is necessary to fix the support base plate 7 to the ground, a suitable threaded groove is opened on the ground at the corresponding placement position, or a corresponding threaded sleeve is pre-embedded for use with bolts for fixation. This solution uses a first stabilizing component to stabilize the support base plate 7, minimizing vibration and noise. Specifically, a loading hole 901 is first opened on the support base plate 7, and the loading hole 901 passes through the shock-absorbing pad 8. Then, a rubber damping inner sleeve 902 is inserted into the loading hole 901. Next, a fixing threaded post 904 is inserted into the rubber damping inner sleeve 902, and is flush with the ground. The threaded connection is achieved by using a pre-embedded threaded sleeve or a threaded groove until the fixed threaded post 904 is tightened, ensuring that the connecting disc 905 at one end of the fixed threaded post 904 is in close contact with the supporting base plate 7. Finally, the sound-absorbing cotton post 908 is inserted into the through groove 907 in the fixed threaded post 904. The rubber damping inner sleeve 902 provides a shock-absorbing auxiliary function for the fixed threaded post 904 and the supporting base plate 7, and improves the connection stability of the fixed threaded post 904. Furthermore, a first auxiliary hole 903 is provided in the rubber damping inner sleeve 902, and a second auxiliary hole is provided on the side wall of the fixed threaded post 904. The purpose of 909 is that both can be used in conjunction with the sound-absorbing cotton column 908 in the through-groove 907. This provides noise absorption at the connection point between the fixed threaded column 904 and the support base plate 7. The first stabilizing component includes a loading hole 901, a rubber damping inner sleeve 902, a first auxiliary hole 903, a fixed threaded column 904, a connecting disc 905, a hexagonal screw head 906, the through-groove 907, the sound-absorbing cotton column 908, the second auxiliary hole 909, and fasteners. The loading hole 901 is disposed through the support base plate 7 and the vibration damping pad 8, and a [missing information - likely a device or component] is embedded within the loading hole 901. A rubber damping inner sleeve 902 has first auxiliary holes 903 evenly arranged on its sidewalls. A fixed threaded post 904 is inserted into the rubber damping inner sleeve 902, and a connecting disc 905 is fixedly arranged at one end of the fixed threaded post 904. A hexagonal screw head 906 is fixedly arranged on one side of the connecting disc 905. A through groove 907 is provided through the fixed threaded post 904, and the through groove 907 extends sequentially into the connecting disc 905 and the hexagonal screw head 906. Second auxiliary holes 909 are evenly arranged on the sidewalls of the fixed threaded post 904, and the second auxiliary holes 909 are connected to the through groove 907.
[0036] To further improve the connection stability of the fixed threaded post 904 to the supporting base plate 7, this solution also uses corresponding fasteners for locking. These fasteners include annular threaded groove 1001, annular retaining groove 1002, a fastening cap 1003, a rotating auxiliary protrusion 1004, and a locking structure. The annular threaded groove 1001 is located on the top of the supporting base plate 7 and is positioned on the side of the loading hole 901. The annular retaining groove 1002 is located on the side of the connecting disc 905. The cap of the fastening cap 1003 is threaded to fit the annular threaded groove 1001. A rotating auxiliary protrusion 1004 is fixedly installed on the side of the cap of the fastening cap 1003, and the fastening cap 1003 is locked by the locking structure. The locking structure includes a threaded through hole 1101, a locking screw 1102, and a knob 1103. The threaded through hole 1101 is located on the side of the fastening cap 1003. Furthermore, the threaded through hole 1101 is threadedly connected to the locking screw 1102, and a knob 1103 is fixedly provided at one end of the locking screw 1102. After the fixed threaded post 904 is tightened and installed, the cap of the fastening cap 1003 is threadedly connected to the annular threaded groove 1001 until the fastening cap 1003 is tightened. The purpose of providing a rotating auxiliary protrusion 1004 at the top of the fastening cap 1003 is to facilitate its tightening and loosening. When the fastening cap 1003 is tightened, the top of the inner cavity of the fastening cap 1003 contacts and presses against the hexagonal screw head 906. On the other hand, the threaded through hole 1101 on the side of the fastening cap 1003 is aligned with the annular groove 1002 on the side of the connecting disc 905. Then, the locking screw 1102 is threaded into the threaded through hole 1101 until one end of the locking screw 1102 is engaged in the annular groove 1002.
[0037] If, when placing the explosion-proof fan, it is inconvenient to create threaded grooves or pre-embed threaded sleeves on the supporting ground, it cannot be used in conjunction with the fixed threaded post 904 to stabilize and reduce noise on the support base plate 7. In this case, the support base plate 7 is placed directly on the workstation floor. Therefore, this solution uses a second stabilizing component to stabilize the support base plate 7, preventing it from shifting due to vibration and generating noise. After the support base plate 7 is placed, the shock-absorbing pad 8 at the bottom of the support base plate 7 provides stability and noise reduction. The second stabilizing component includes a load-bearing body 1201, an adhesive pad 1202, an extension plate 1203, an auxiliary baffle 1204, and a screw rod. 1205, auxiliary handle 1206, stabilizing pressure plate 1207, rubber auxiliary pad 1208, and auxiliary components; an adhesive pad 1202 is fixedly installed at the bottom end of the support body 1201, and an extension plate 1203 is fixedly installed on one side of the top end of the support body 1201. An auxiliary baffle 1204 is fixedly installed on the bottom side of the extension plate 1203, and the auxiliary baffle 1204 is vertically installed; a screw rod 1205 is threadedly connected through the extension plate 1203, an auxiliary handle 1206 is fixedly installed at the top end of the screw rod 1205, and a stabilizing pressure plate 1207 is fixedly installed at the bottom end of the screw rod 1205. A rubber auxiliary pad 1208 is fixedly installed at the bottom end of the stabilizing pressure plate 1207.
[0038] First, the auxiliary baffle 1204 on the bottom side of the extension plate 1203 is tightly attached to the side wall of the support base plate 7. Then, the auxiliary baffle 1204 is slowly moved down until the adhesive pad 1202 at the bottom of the bearing 1201 is attached to the support surface. After the attachment is secure, the screw rod 1205 is rotated by the auxiliary handle 1206, causing the screw rod 1205 to push down the stabilizing pressure plate 1207 until the stabilizing pressure plate 1207 presses against the support base plate 7. Then, the screw rod 1205 is tightened. The screw rod 1205 in the extension plate 1203 presses down on the stabilizing pressure plate 1207, causing the stabilizing pressure plate 1207 to press against the top of the support base plate 7. This has a positioning function for the support base plate 7 in the vertical direction and has a positive effect on preventing shaking and reducing noise.
[0039] An auxiliary component is provided on the other side of the top of the support body 1201. The auxiliary component includes a connecting column 1301, a connecting screw 1302, an adjusting handle 1303, an auxiliary bearing 1304, an extension protrusion 1305, and a stabilizing pressure body 1306. The connecting column 1301 is equidistantly fixed on the top side wall of the support body 1201 and is inclined. The connecting screw 1302 is threaded through the connecting column 1301. The adjusting handle 1303 is fixedly installed at the top of the connecting screw 1302. The auxiliary bearing 1304 is sleeved at the bottom of the connecting screw 1302 and is embedded and fixedly installed in the extension protrusion 1305. The extension protrusion 1305 is fixed. The stabilizing pressure body 1306 is installed on the connecting screw 1302. The number of stabilizing pressure bodies 1306 and connecting screw 1302 are connected. One stabilizing pressure body 1306 is installed at the bottom of each connecting screw 1302, and the bottom end of the stabilizing pressure body 1306 is provided with a horizontal surface. By rotating the connecting screw 1302 with the control handle 1303, one end of the connecting screw 1302 pushes the stabilizing pressure body 1306. During this process, one hand needs to rotate the control handle 1303 and the other hand needs to hold the stabilizing pressure body 1306. The purpose is to ensure that the horizontal surface at the bottom end of the stabilizing pressure body 1306 is parallel to the supporting ground until the horizontal surface finally contacts the supporting ground. Finally, the connecting screw 1302 is tightened by the control handle 1303.
