And then the materials are stirred by the disturbance device at the discharge port and smoothly fall off from the discharge port.

Description

Technical Field

[0001] The utility model relates to an arch breaking device, in particular to a powder material arch breaking device. Background Art

[0002] Since powders with poor fluidity or high solid content are prone to agglomeration and accumulation at the bottom of the storage tank, it is difficult for the powder to fall smoothly from the discharge port at the bottom of the storage tank. The existing method is to set stirring blades at the central axis position in the storage tank so that the powder around the central axis is stirred by the blades and becomes loose, allowing the powder around the central axis to fall from the discharge port. However, in this structure, part of the powder around the central axis will be thrown to the surroundings by the stirring blades, and the powder sticking to the inner wall of the storage tank will have difficulty flowing downward automatically, resulting in a low falling speed and efficiency of the entire powder, which is difficult to meet the requirements of large-scale use of powder.

[0015] As a preferred solution, the horizontal section is arranged in the discharge port of the storage tank, and the non-horizontal section extends into the storage tank above the discharge port.

[0021] As a preferred solution, the lower end of the rotating rod extends into the discharge port of the storage tank, and a first stirring rod is provided on the rotating rod located in the discharge port of the storage tank.

[0022] As a preferred solution, the blade is provided with a second stirring rod for disturbing the powder around the blade.

[0023] As a preferred solution, a third stirring rod is provided on the spiral stirring blade.

[0024] The implementation of this utility model has the following beneficial effects:

[0025] 1. The utility model uses a disturbance device to break the arch of a certain thickness of powder on the inner wall of the storage tank, so that the powder near the inner wall of the storage tank can flow and flow to the discharge port under the action of its own gravity, so that the powder in the powder storage tank can fall evenly and smoothly. When the disturbance device stirs the powder at the discharge port and the inner wall of the storage tank at the same time, as the powder at the discharge port is stirred by the disturbance device and falls from the discharge port, the powder on the inner wall of the storage tank is stirred by the disturbance device and flows downward along the inner wall of the storage tank to the discharge port under its own gravity, and then is stirred by the disturbance device at the discharge port and falls smoothly from the discharge port.

[0026] 2. The parallel blades of the utility model stir and break the arch of the powder on the inner wall of the storage tank, so that the powder flows to the center of the storage tank and the discharge port under gravity. At the same time, the cross blades stir and break the arch of the powder around the center of the storage tank, so that the powder flowing from the inner wall of the storage tank to the center of the storage tank is stirred again, so that the powder remains in a flowing state.

[0027] 3. The blades and spiral stirring blades of the utility model can stir the powder on the inner wall of the entire storage tank, and can also stir the powder in the discharge port, thereby achieving the function and purpose of stirring the powder on the inner wall of the storage tank and the discharge port at the same time, and has the advantages of all-round arch breaking and high work efficiency.

[0028] 4. When the lower end of the spiral stirring blade is vertically close to the upper end of the blade, there is an area between the spiral stirring blade and the blade that is not stirred by both. At this time, the flow rate of the powder in this undisturbed area is slower, so that the powder in the storage tank has different flow rates, reducing the occurrence of accumulation without causing accumulation problems. When the lower end of the spiral stirring blade and the upper end of the blade are in contact or intersecting in the vertical direction, the blade and the spiral stirring blade can stir the powder on the inner wall of the entire storage tank, thereby stirring the powder on the entire inner wall of the storage tank, increasing the flow rate of the powder and preventing the problem of accumulation in local areas.

[0029] 5. When the rotating rod drives the spiral stirring blades and blades to rotate, the spiral stirring blades and blades can perform staggered stirring and arch breaking at different positions in the circumferential direction on the inner wall of the storage tank, so that the powder flowing downward from the stirring area of ​​the spiral stirring blades can be stirred by the blades in a timely and rapid manner when it flows to the stirring area of ​​the blades, reducing the possibility of powder accumulation.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] Reference Figures 1 to 4 This embodiment relates to a powder arch-breaking device, comprising a storage tank 1 for storing and discharging powder, and a disturbance device 2 for stirring the powder in the storage tank 1; a discharge port 11 is provided at the bottom end of the storage tank 1, and the disturbance device 2 stirs the powder accumulated at the discharge port 11 and / or the inner wall of the storage tank 1, causing the powder to fall from the discharge port 11.

[0041] Since the powder in the storage tank 1 tends to accumulate at the discharge port, especially for the storage tank 1 with a funnel-shaped inner wall, the powder of a certain thickness that contacts and is close to the inner wall will have poor fluidity and cannot flow out of the discharge port 11 under its own gravity. The present device provides a disturbance device 2 in the storage tank 1 to stir the powder at the discharge port 11, so that the powder in the storage tank 1 will not accumulate at the discharge port 11, and the powder can fall from the discharge port 11 under its own gravity. It can be seen that the disturbance device 2 breaks the arch of the powder of a certain thickness on the inner wall of the storage tank 1, so that the powder close to the inner wall of the storage tank 1 can flow and flow to the discharge port 11 under the action of its own gravity, so that the powder in the powder storage tank 1 can fall evenly and smoothly. When the disturbance device 2 simultaneously stirs the powder at the discharge port 11 and the inner wall of the storage tank 1, as the powder at the discharge port 11 is stirred by the disturbance device 2 and falls from the discharge port 11, the powder on the inner wall of the storage tank 1 is stirred by the disturbance device 2 and flows downward along the inner wall of the storage tank 1 to the discharge port 11 under its own gravity, and is then stirred by the disturbance device 2 at the discharge port 11 and falls smoothly from the discharge port 11. The disturbance device 2 of the present device can stir the powder at the discharge port 11 alone, or stir the powder near the inner wall of the storage tank 1 alone, or stir the powder at the discharge port 11 and the powder near the inner wall of the storage tank 1 at the same time.

[0042] The agitation device 2 includes a rotating rod 21 disposed on the central axis of the storage tank 1, and blades 22 mounted on the rotating rod 21. The blades 22 stir the discharge port 11 and / or the powder accumulated on the inner wall of the storage tank 1. During operation, the rotating rod 21 drives the blades 22 to stir the powder in the discharge port 11, so that the powder in the storage tank 1 does not accumulate at the discharge port 11, allowing the powder to fall from the discharge port 11 under its own gravity. The rotating rod 21 can also drive the blades 22 to stir a certain thickness of powder on the inner wall of the storage tank 1, so that the powder near the inner wall of the storage tank 1 can flow and flow toward the discharge port 11 under the action of its own gravity, so that the powder in the powder storage tank 1 can fall evenly and smoothly. It can be seen that the rotating rod 21 drives the blades 22 to stir the discharge port 11 and the powder near the inner wall of the storage tank 1 at the same time, so that the powder of a certain thickness near the inner wall of the storage tank 1 can flow to the discharge port 11, and will not accumulate and fall down under the stirring action of the blades 22 at the discharge port 11.

[0043] like Figure 1 and Figure 3As shown, the blades 22 include parallel blades 221 parallel to the inner wall of the storage tank 1, and cross blades 222 intersecting the inner wall of the storage tank 1. The parallel blades 221 stir and break the powder on the inner wall of the storage tank 1, causing the powder to flow toward the center of the storage tank 1 and the discharge port 11 under gravity. At the same time, the cross blades 222 stir and break the powder around the center of the storage tank 1, causing the powder flowing from the inner wall of the storage tank 1 to the center of the storage tank 1 to be stirred again, so that the powder remains in a flowing state, completely solving the problem of powder accumulation.

[0044] The blade 22 includes a horizontal section 223 and a non-horizontal section 224. One end of the horizontal section 223 is connected to the rotating rod 21, and the other end is connected to the non-horizontal section 224. The horizontal section 223 serves to connect the rotating rod 21 and the non-horizontal section 224. When the rotating rod 21 drives the horizontal section 223 to rotate, the horizontal section 223 stirs the powder around the rotating rod 21, while the non-horizontal section 224 stirs the powder near a certain thickness on the inner wall of the storage tank 1, thereby simultaneously breaking the arch of the powder around the rotating rod 21 and on the inner wall of the storage tank 1.

[0045] The horizontal section 223 is disposed within the discharge port 11 of the storage tank 1, while the non-horizontal section 224 extends into the storage tank 1 above the discharge port 11. The non-horizontal section 224 extends into the storage tank 1 and is positioned close to the inner wall of the storage tank 1. When the rotating rod 21 drives the non-horizontal section 224 to rotate, the non-horizontal section 224 stirs a certain thickness of powder on the inner wall of the storage tank 1. Simultaneously, the horizontal section 223 not only connects the rotating rod 21 and the non-horizontal section 224, but also serves to horizontally break the powder in the discharge port 11.

[0046] A spiral stirring blade 211 is spirally wound around the outer circumference of the rotating rod 21, and the spiral stirring blade 211 is arranged close to the inner wall of the storage tank 1. The spiral stirring blade 211 is connected to the rotating rod 21 by a connecting rod 6. The spiral stirring blade 211 stirs the powder on the inner wall of the storage tank 1 above the blade 22, that is, the blade 22 and the spiral stirring blade 211 can stir the powder on the inner wall of the entire storage tank 1, and can also stir the powder in the discharge port 11, thereby achieving the function and purpose of stirring the powder on the inner wall of the storage tank 1 and the discharge port 11 at the same time, having the advantages of all-round arch breaking and high work efficiency, and perfectly solving the problem of powder accumulation.

[0047] The upper end of the spiral stirring blade 211 is close to the upper end of the inner wall of the storage tank 1, and the lower end of the spiral stirring blade 211 is close to, or contacts, or crosses the upper end of the blade 22 in the vertical direction. When the lower end of the spiral stirring blade 211 is close to the upper end of the blade 22 in the vertical direction, there is an area between the spiral stirring blade 211 and the blade 22 that is not stirred by both. At this time, the flow rate of the powder in the unstirred area is slow, so that the powder in the storage tank 1 has different flow rates, reducing the generation of accumulation, but does not cause the problem of accumulation. When the lower end of the spiral stirring blade 211 is in contact with or crosses the upper end of the blade 22 in the vertical direction, the blade 22 and the spiral stirring blade 211 can stir the powder on the inner wall of the entire storage tank 1, thereby stirring the powder on the entire inner wall of the storage tank 1, increasing the flow rate of the powder and preventing the problem of accumulation in local areas.

[0048] The lower end of the spiral stirring blade 211 is staggered from the upper end of the blade 22 in the horizontal and circumferential directions. When the rotating rod 21 drives the spiral stirring blade 211 and the blade 22 to rotate, the spiral stirring blade 211 and the blade 22 can staggeredly stir and break the arch at different circumferential positions on the inner wall of the storage tank 1. As a result, the powder flowing downward from the stirring area of ​​the spiral stirring blade 211 can be stirred promptly and quickly by the blade 22 when it flows into the stirring area of ​​the blade 22, reducing the possibility of powder accumulation.

[0049] like Figure 1 As shown, the inner wall of the storage tank 1 is funnel-shaped; the spiral diameter of the spiral stirring blade 211 gradually decreases from top to bottom along the central axis of the rotating rod 21. The spiral stirring blade 211 with a gradually decreasing diameter corresponds to the funnel-shaped inner wall of the storage tank 1, allowing the spiral stirring blade 211 to better approach the inner wall of the storage tank 1, thereby allowing the spiral stirring blade 211 to stir the powder on the entire inner wall of the storage tank 1.

[0050] The lower end of the rotating rod 21 extends into the discharge port 11 of the storage tank 1. A first stirring rod 3 is provided on the rotating rod 21 located within the discharge port 11 of the storage tank 1. The lower end of the rotating rod 21 extends into the discharge port 11, and the first stirring rod 3 is provided thereon. When the rotating rod 21 rotates, the first stirring rod 3 stirs the powdered material surrounding the rotating rod 21. Furthermore, the first stirring rod 3, when used in conjunction with the blades 22 within the discharge port 11, stirs the powdered material in various areas within the discharge port 11, effectively preventing the accumulation of powdered material within the discharge port 11.

[0051] Similarly, the blade 22 may also be provided with a second stirring rod 4 for agitating the powder around the blade 22. The second stirring rod 4 can agitate the powder on the side of the blade 22 near the center of the discharge port 11. When used in conjunction with the first stirring rod, the second stirring rod 4 can agitate the powder in the discharge port 11 in all directions, achieving higher stirring efficiency and better arch breaking effect.

[0052] The spiral stirring blade 211 is provided with a third stirring rod 5. The third stirring rod 5 can stir the powder on one side of the spiral stirring blade 211 close to the center of the storage tank 1.

[0053] Example 2

[0054] This embodiment is based on the embodiment 1, as an improvement to the structure of the blade 22. Figure 2 and Figure 4 As shown, the blades 22 used in this embodiment include parallel blades 221 parallel to the inner wall of the storage tank 1. The parallel blades 221 stir the powder on the inner wall of the storage tank 1, causing the powder to flow toward the center of the storage tank 1 and the discharge port 11 under the force of gravity. The lower portion of the parallel blades 221 is located within the discharge port 11 of the storage tank 1 and stirs the powder in the discharge port 11 to prevent powder accumulation at the discharge port 11. At the same time, the upper portion of the parallel blades 221 extends into the storage tank 1 above the discharge port 11 and stirs a certain thickness of powder on the inner wall of the storage tank 1, causing the powder to flow toward the center of the storage tank 1 and the discharge port 11 under the force of gravity.

[0055] The parallel blades 221 include a horizontal section 223 and a non-horizontal section 224. One end of the horizontal section 223 is connected to the rotating rod 21, and the other end of the horizontal section 223 is connected to the non-horizontal section 224. The non-horizontal section 224 extends into the storage tank 1 and is positioned close to the inner wall of the storage tank 1. When the rotating rod 21 drives the non-horizontal section 224 to rotate, the non-horizontal section 224 stirs a certain thickness of powder on the inner wall of the storage tank 1. At the same time, the horizontal section 223 not only connects the rotating rod 21 and the non-horizontal section 224, but also stirs the powder in the discharge port 11 in a horizontal direction.

[0056] Example 3

[0057] This embodiment is based on the embodiment 1, as an improvement to the structure of the blade 22. Figure 5As shown, the blade 22 includes a lower blade 225 disposed within the discharge port 11. The lower blade 225 stirs the powdered material in the discharge port 11. The lower blade 225 of this structure stirs only the powdered material in the discharge port 11, solving the problem of powdered material easily accumulating at the discharge port 11. The lower blade 225 is in an inverted U-shape and includes a horizontal section 223 and a non-horizontal section 224. One end of the horizontal section 223 is connected to the rotating rod 21, and the other end of the horizontal section 223 is connected to the non-horizontal section 224. The non-horizontal section 224 is disposed near the inner wall of the discharge port 11. When the rotating rod 21 drives the non-horizontal section 224 to rotate, the non-horizontal section 224 stirs the powdered material in the discharge port 11 vertically. Simultaneously, the horizontal section 223 serves both to connect the rotating rod 21 and the non-horizontal section 224 and to stir the powdered material in the discharge port 11 horizontally.

[0058] Example 4

[0059] This embodiment is based on the embodiment 1, as an improvement to the structure of the blade 22. Figure 6 and Figure 7 As shown, the blade 22 used in this embodiment includes a lower blade 225 and an upper blade 226. The lower blade 225 is arranged in the discharge port 11 of the storage tank 1 to stir the powder in the discharge port 11 so that the discharge port 11 does not produce a situation where the powder accumulates. At the same time, the upper blade 226 extends into the storage tank 1 above the discharge port 11 to stir the powder of a certain thickness on the inner wall of the storage tank 1, so that the powder flows toward the center of the storage tank 1 and the discharge port 11 under the force of gravity. This structure cleverly arranges the lower part (lower blade 225) and the upper part (upper blade 226) of the blade 22 in the discharge port 11 and in the storage tank 1 respectively, so as to achieve simultaneous stirring of the powder at the discharge port 11 and the inner wall of the storage tank 1, ensuring that the powder at each position in the storage tank 1 can flow toward the discharge port 11.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
