Description

Technical Field

[0001] The utility model relates to the field of air flow vibration of powder bins, in particular to an air flow vibration device for powder bins. Background Technique

[0002] A powder bin is a device used for storing and transporting powder and granular materials. During the transportation of powder and granular materials, phenomena such as "bridging", "arching", and "rat holes" may occur in the materials, thus blocking the outlet of the powder bin. Therefore, an air flow vibration device is required. Among them, the "air flow vibration device for powder bins" disclosed in the application number "CN202022342941.7" is also an increasingly mature technology. The air flow vibration device for powder bins provided by the utility model has gas nozzles arranged on both sides of the feeding port and is connected to a compressed air source. When a "bridging phenomenon" occurs in the feeding port during the feeding of the powder bin, the compressed air is introduced into the gas nozzles by controlling the solenoid valve, and the powder material at the "bridging" position is blown to disperse it and dredge the feeding port; a dust collector is arranged on the upper part of the powder bin, which can discharge the ejected compressed air, while the powder material is intercepted to avoid polluting the atmosphere and wasting. Moreover, the air flow vibration device for powder bins provided by the utility model is simple to operate and has strong applicability. However, during the use of this vibration device, there are still the following defects: although the vibration device can indeed achieve a vibration effect by setting the solenoid valve to compress the gas into the nozzle, the above structure is simple, so the vibration effect achieved is not significant enough. Based on this, it is necessary to provide an air flow vibration device that can significantly improve the vibration effect and the dredging performance of powder and granular materials. In addition, the stability of this air flow vibration device during installation with the powder bin needs to be improved. Based on this, it is necessary to provide an air flow vibration device that can improve the installation stability and thus improve the use safety. Content of the Utility Model

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1-6 , the present invention provides a pneumatic vibration device for a powder bin, including a mounting assembly 100 and a vibration assembly 200;

[0026] Among them, the mounting assembly 100 includes a mounting plate 101. A plurality of mounting blocks 102 are fixedly connected to the side surface of the mounting plate 101. A protective sheet 103 is connected to the lower end of the mounting plate 101. A protective block 104 is fixedly connected to the lower end of the protective sheet 103. A plurality of suction cups 105 are detachably connected to the lower end of the mounting plate 101. Air extraction heads 106 are fixedly connected to the surfaces of the plurality of suction cups 105;

[0027] The vibration assembly 200 includes a first vibration housing 201 and a second vibration housing 202 mounted on the upper end of the mounting plate 101. A connecting flange 203 is fixedly connected to the surface of the first vibration housing 201. A vibration gear 204 is installed inside the first vibration housing 201 and the second vibration housing 202. A plurality of second screw holes 205 are formed on the surface of the vibration gear 204. Counterweight bolts 206 are threadedly connected to the interiors of three of the second screw holes 205. Connecting shafts 207 are fixedly connected to both sides of the vibration gear 204. Bearings 208 are sleeved on the surfaces of the connecting shafts 207.

[0028] In a specific embodiment, the installation component 100 and the vibration component 200 are configured to not only enhance the installation stability between the vibration device and the powder bin, thereby improving the use safety of the air flow vibration device, but also enhance the air flow vibration effect, and further enhance the practicality of the vibration device. When in use, first, the protective piece 103 and the protective block 104 at the lower end of the mounting plate 101 are attached to the surface of the powder bin. The protective piece 103 and the protective block 104 can increase the friction between the mounting plate 101 and the bin, initially improving the stability. At the same time, a plurality of suction cups 105 are adsorbed on the surface of the bin. At this time, the suction device is connected to the suction head 106, so that the air in the suction cup 105 can be pumped out to form a vacuum inside, thereby significantly enhancing the connection and installation strength between the mounting plate 101 and the bin. Subsequently, strong air flow is conveyed into the first vibration shell 201 and the second vibration shell 202 through the connection flange 203 by an external air supply device. The strong air flow can blow the vibration gear 204 and the connecting shafts 207 on both sides thereof to rotate around the bearing 208. At this time, the three counterweight bolts 206 on one side of the vibration gear 204 can increase the weight on one side of the vibration gear 204 and change the center of gravity position. When the vibration gear 204 rotates to the top or bottom, it can drive the first vibration shell 201 and the second vibration shell 202 to vibrate. At this time, when the first vibration shell 201 and the second vibration shell 202 contact the surface of the bin, the vibration force can be transmitted to the bin, thereby being able to achieve the effect of dredging the powder and enhancing the practicality of the vibration device.

[0029] Please refer to Figure 2 and Figure 3 , first screw holes 111 are formed on the surfaces of a plurality of mounting blocks 102, and a screw block 112 is fixedly connected to the upper end of the suction cup 105. The screw block 112 is threadedly connected inside the first screw hole 111.

[0030] In a specific embodiment, the threaded connection of the screw block 112 inside the first screw hole 111 can not only enhance the connection strength between the suction cup 105 and the mounting plate 101, but also facilitate the disassembly of the suction cup 105 as needed.

[0031] Please refer to Figure 2 and Figure 3 , two T-shaped grooves 121 are formed at the upper end of the mounting plate 101.

[0032] In a specific embodiment, the T-shaped grooves 121 are used to guide the first vibration shell 201 and the second vibration shell 202.

[0033] Please refer to Figures 4-6, at the upper ends of the first vibration housing 201 and the second vibration housing 202, two ear blocks 211 are fixedly connected. Third screw holes 212 are formed on the surfaces of the two ear blocks 211. A third bolt 213 is threadedly connected inside the third screw hole 212, and one end of the third bolt 213 is threadedly connected with a third nut 214.

[0034] In a specific embodiment, by threading the third bolt 213 inside the third screw hole 212 and cooperating with the third nut 214, the connection strength and tightness between the first vibration housing 201 and the second vibration housing 202 can be enhanced, and the vibration effect of the vibration device can be improved.

[0035] Please refer to Figures 4-6 , on one side of the first vibration housing 201, a sealing block 221 is fixedly connected. On one side of the second vibration housing 202, a sealing groove 222 is formed. The sealing block 221 is snap-fitted inside the sealing groove 222.

[0036] In a specific embodiment, the sealing block 221 being snap-fitted inside the sealing groove 222 can further enhance the connection tightness between the first vibration housing 201 and the second vibration housing 202, avoid strong air leakage, and ensure the vibration frequency and intensity of the vibration device.

[0037] Please refer to Figures 4-6 , on the opposite surfaces of the first vibration housing 201 and the second vibration housing 202, a first installation groove 231 and two second installation grooves 232 are formed. The vibration gear 204 is installed inside the first installation groove 231, and the two bearings 208 are both installed inside the second installation grooves 232.

[0038] In a specific embodiment, the first installation groove 231 and the second installation grooves 232 can improve the installation stability of the vibration gear 204 and the bearings 208.

[0039] Please refer to Figures 4-6 , at the lower ends of the first vibration housing 201 and the second vibration housing 202, two T-shaped blocks 241 are fixedly connected. The two T-shaped blocks 241 are both slidably connected inside the T-shaped groove 121.

[0040] In a specific embodiment, the T-shaped blocks 241 are snap-fitted inside the T-shaped groove 121. When the T-shaped blocks 241 slide along the T-shaped groove 121, the first vibration housing 201 and the second vibration housing 202 can be controlled to move away from or close to each other, improving the disassembly and assembly convenience of the vibration gear 204.

[0041] Please refer to Figure 2 and Figure 3 , the protective sheet 103 and the protective block 104 are both made of rubber.

[0042] In a specific embodiment, the protective sheet 103 and the protective block 104 made of rubber can protect the mounting plate 101 and the silo, thereby extending the service life of the vibration device.

[0043] Working principle: During use, first, the protective sheet 103 and the protective block 104 at the lower end of the mounting plate 101 are attached to the surface of the powder silo. Under the action of the protective sheet 103 and the protective block 104, the friction between the mounting plate 101 and the silo can be increased to initially improve the stability of the mounting plate 101. At this time, several suction cups 105 adsorb on the surface of the silo. Subsequently, an air extraction device is connected to the air extraction head 106 and the air inside the suction cups 105 is extracted to make the inside of the suction cups 105 in a vacuum state, thereby significantly enhancing the connection and installation strength between the mounting plate 101 and the silo. When dredging powder and granular materials, first, a strong air flow is conveyed into the first vibration shell 201 and the second vibration shell 202 through the connecting flange 203 by an external air conveying device. The strong air flow blows the vibration gear 204 and the connecting shafts 207 on both sides of it to rotate around the bearing 208. Since the three counterweight bolts 206 on one side of the vibration gear 204 can increase the weight on one side of the vibration gear 204 and change the center of gravity position, when the vibration gear 204 rotates to the top or bottom, it can drive the first vibration shell 201 and the second vibration shell 202 to vibrate. At this time, when the first vibration shell 201 and the second vibration shell 202 contact the surface of the silo, the vibration force can be transmitted to the silo, thereby achieving the effect of dredging powder to avoid blockage, and further enhancing the practicability of the vibration device.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
