Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aluminum ash conveying equipment, and specifically to a conveying device for aluminum ash. Background Technology
[0002] In aluminum ash processing, ordinary ball valves are typically installed on the conveying pipeline to control the opening and closing of the pipeline. The material conveyed is fine aluminum ash powder containing salt. The aluminum ash adheres to the inner surface of the ball valve, and the valve body wears down with the aluminum ash during rotation, resulting in a high failure rate of the ball valve. This increases the cost and reduces the efficiency of aluminum ash conveying. Therefore, there is an urgent need for a conveying device specifically designed for aluminum ash to solve these problems. Utility Model Content
[0003] To address the technical problem of aluminum ash adhering to the inner surface of ball valves and causing wear on the valve body during rotation, this invention provides an aluminum ash conveying device. This device has a simple structure, replaces traditional ball valves, and enables the opening and closing of the conveying pipeline. It offers good sealing and low loss.
[0004] This utility model provides a conveying device for aluminum ash, including a conveying pipe and a sealing structure. The sealing structure includes a spherical outer shell and a rubber bladder. The spherical outer shell is disposed on the conveying pipe and is connected to the conveying pipe. The rubber bladder is disposed inside the spherical outer shell and is used to open or close the connection point between the spherical outer shell and the conveying pipe. A three-way valve is disposed on the spherical outer shell. One of the valve ports of the three-way valve is connected to the rubber bladder, and the other two valve ports of the three-way valve are fixedly connected to an air compressor and a vacuum pump, respectively.
[0005] Furthermore, the conveying device also includes a fixing structure, which comprises multiple suction nozzles evenly arranged on the top of the spherical shell. The air inlets of the multiple suction nozzles are connected through a suction pipe located outside the spherical shell. The suction pipe is fixedly connected to a vacuum pump, and the air outlets of the multiple suction nozzles all face inward towards the rubber bladder. When the air compressor is turned off and the vacuum pump is started, the vacuum pump draws away the high-pressure gas inside the rubber bladder. Simultaneously, the vacuum pump causes the suction nozzles to adhere to the outer wall of the rubber bladder, further ensuring that the rubber bladder is stably attached to the first sealing gasket.
[0006] Furthermore, the top of the spherical shell is evenly provided with multiple fixing holes, and each suction nozzle is fixedly connected to the fixing hole. The suction nozzle is fixed to the top of the spherical shell through the fixing holes.
[0007] Furthermore, a first sealing gasket is provided between the upper part of the inner wall of the spherical outer shell and the outer wall of the rubber bladder, and a first notch is provided at the position corresponding to the air outlet of the suction nozzle. The first sealing gasket not only fixes the upper part of the inner wall of the spherical outer shell to the outer wall of the rubber bladder, but also further ensures that the rubber bladder is stably attached to the first sealing gasket.
[0008] Furthermore, the conveying device also includes a backflushing structure, which comprises a backflushing pipe and multiple backflushing holes evenly distributed at the bottom of the spherical shell. The backflushing pipe is fixedly connected to the air compressor, and multiple connecting pipes are provided on the backflushing pipe. Each backflushing hole is equipped with a valve, and each valve is fixedly connected to a connecting pipe. When the air compressor is turned off and the vacuum pump is started, the vacuum pump draws away the high-pressure gas inside the rubber bladder, causing the rubber bladder to deflate. At this time, the valve is opened, and high-pressure gas is introduced into the backflushing pipe. The high-pressure gas in the backflushing pipe enters the interior of the spherical shell and blows towards the rubber bladder, further ensuring that the rubber bladder is stably attached to the upper part of the inner wall of the spherical shell.
[0009] Furthermore, a second sealing gasket is provided at the lower part of the inner wall of the spherical outer shell, and a second notch is provided at the position corresponding to the backflush hole on the second sealing gasket. The second sealing gasket prevents aluminum ash powder from entering between the outer wall of the rubber bladder and the inner wall of the spherical outer shell when the connection point between the rubber bladder and the conveying pipe is closed, thus affecting the seal of the rubber bladder. The second notch ensures that the high-pressure gas in the backflush pipe enters the interior of the spherical outer shell and is blown towards the rubber bladder.
[0010] Furthermore, the second sealing gasket is provided with an embedded groove, and a protrusion matching the embedded groove is fixedly connected to the outer wall of the rubber bladder. The protrusion can be locked in the embedded groove. When the rubber bladder is inflated, the connection point between the spherical outer shell and the conveying pipe is closed. The protrusion on the rubber bladder is locked in the embedded groove. The cooperation between the protrusion and the embedded groove can further prevent aluminum dust powder from entering between the outer wall of the rubber bladder and the inner wall of the spherical outer shell, thereby improving the sealing performance of the rubber bladder.
[0011] Compared with the prior art, the present invention has the following technical effects:
[0012] The material transported by the conveying pipeline is fine aluminum ash powder containing salt. When the air compressor is started and the vacuum pump is turned off, the three-way valve is opened, allowing high-pressure gas generated by the air compressor to enter the rubber bladder through the three-way valve. The rubber bladder inflates, and at this point, the connection between the rubber bladder and the spherical outer shell and the conveying pipeline closes, stopping the conveying of material. When the air compressor is turned off and the vacuum pump is started, the three-way valve opens, and the vacuum pump removes the high-pressure gas from inside the rubber bladder, causing it to deflate. The rubber bladder then completely adheres to the upper part of the inner wall of the spherical outer shell, and the connection between the spherical outer shell and the conveying pipeline opens, allowing the conveying pipeline to continue transporting material. This new conveying device has a simple structure and is easy to use. It replaces the traditional ball valve to open or close the conveying pipeline, providing good sealing and low loss.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1-3As shown, a conveying device for aluminum ash includes a conveying pipe 1 and a sealing structure. The sealing structure includes a spherical outer shell 2 and a rubber bladder 3. The spherical outer shell 2 is disposed on the conveying pipe 1 and is connected to the conveying pipe 1. The rubber bladder 3 is disposed inside the spherical outer shell 2 and is used to open or close the connection point between the spherical outer shell 2 and the conveying pipe 1. A three-way valve 21 is disposed on the spherical outer shell 2. One valve port of the three-way valve 21 is connected to the rubber bladder 3, and the other two valve ports of the three-way valve 21 are fixedly connected to an air compressor 7 and a vacuum pump 8, respectively. The other two valve ports of the three-way valve 21 are fixedly connected to the air outlet of the air compressor 7 and the vacuum pump 8, respectively. The conveying pipe 1 and the spherical outer shell 2 can be made of metal, such as steel.
[0024] The conveying process of the conveying device in this embodiment is as follows: The material conveyed by the conveying pipe 1 is fine aluminum ash powder containing salt. The air compressor 7 is started, the vacuum pump 8 is turned off, and the three-way valve 21 is opened, allowing the high-pressure gas generated by the air compressor 7 to enter the rubber bladder 3 through the three-way valve 21. The rubber bladder 3 inflates and expands. At this time, the connection point between the rubber bladder 3 and the spherical outer shell 2 and the conveying pipe 1 is closed, and the conveying pipe 1 stops conveying material. The air compressor 7 is turned off, the vacuum pump 8 is started, and the three-way valve 21 is opened. The vacuum pump 8 removes the high-pressure gas inside the rubber bladder 3, causing the rubber bladder 3 to deflate. At this time, the rubber bladder 3 is completely attached to the upper part of the inner wall of the spherical outer shell 2, and the connection point between the spherical outer shell 2 and the conveying pipe 1 is opened. At this time, the conveying pipe 1 continues to convey material.
[0025] The conveying device in this embodiment has a simple structure and is easy to use. It replaces the traditional ball valve to open or close the conveying pipeline 1, has good sealing performance, and low loss.
[0026] As one possible implementation, the conveying device further includes a fixing structure, which includes multiple suction nozzles 4 evenly arranged on the top of the spherical shell 2. The air inlets of the multiple suction nozzles 4 are connected through a suction pipe 5, which is located outside the spherical shell 2. Specifically, plugs are provided at both ends of the suction pipe 5, and the suction nozzles 4 are fixedly connected to the middle of the suction pipe 5. The middle of the suction pipe 5 is fixedly connected to and communicates with a vacuum pump 8. The air outlets of the multiple suction nozzles 4 all face into the rubber bladder 3. When the air compressor 7 is turned off and the vacuum pump 8 is started, the vacuum pump 8 draws away the high-pressure gas inside the rubber bladder 3. At the same time, the vacuum pump 8 causes the suction nozzles 4 to suck onto the outer wall of the rubber bladder 3, further ensuring that the rubber bladder 3 is stably attached to the upper part of the inner wall of the spherical shell 2.
[0027] In one possible implementation, the top of the spherical shell 2 is evenly provided with multiple fixing holes, and each suction nozzle 4 is fixedly connected to a fixing hole. The suction nozzle 4 is fixed to the top of the spherical shell 2 through the fixing holes.
[0028] In one possible implementation, a first sealing gasket 22 is provided between the upper part of the inner wall of the spherical outer shell 2 and the outer wall of the rubber bladder 3. The first sealing gasket 22 has a first notch at a position corresponding to the air outlet of the suction nozzle 4. The first sealing gasket 22 not only securely connects the upper part of the inner wall of the spherical outer shell 2 to the outer wall of the rubber bladder 3, but also further ensures that the rubber bladder 3 is stably attached to the first sealing gasket 22. Furthermore, the first sealing gasket 22 prevents aluminum ash powder from entering between the outer wall of the rubber bladder 3 and the inner wall of the spherical outer shell 2 when the connection point between the rubber bladder 3 and the spherical outer shell 2 is closed, thus affecting the seal of the rubber bladder 3. The first notch ensures that the suction nozzle 4 can adhere to the outer wall of the rubber bladder 3.
[0029] In one possible implementation, the conveying device further includes a backflushing structure, which comprises a backflushing pipe 6 and multiple backflushing holes evenly distributed at the bottom of the spherical outer shell 2. The backflushing pipe 6 is fixedly connected to and communicates with the air compressor 7. Specifically, one end of the backflushing pipe 6 is fixedly connected to the air outlet of the air compressor 7, and the other end of the backflushing pipe 6 is provided with a plug. Multiple connecting pipes are provided on the backflushing pipe 6, and the multiple connecting pipes are located in the middle of the backflushing pipe 6. Each backflushing hole is provided with a valve, and each valve is fixedly connected to a connecting pipe. When the air compressor 7 is started and the vacuum pump 8 is turned off, the valve is closed, and high-pressure gas is not introduced into the backflushing pipe 6. When the air compressor 7 is turned off and the vacuum pump 8 is started, the vacuum pump 8 draws away the high-pressure gas inside the rubber bladder 3, causing the rubber bladder 3 to deflate. At this time, the valve is opened, and high-pressure gas is introduced into the backflush pipe 6. The high-pressure gas in the backflush pipe 6 enters the interior of the spherical shell 2 and blows towards the rubber bladder 3, further ensuring that the rubber bladder 3 is stably attached to the upper part of the inner wall of the spherical shell 2.
[0030] In one possible implementation, a second sealing gasket 23 is provided on the lower part of the inner wall of the spherical outer shell 2. The second sealing gasket 23 has a second notch at a position corresponding to the backflush hole. The second sealing gasket 23 prevents aluminum ash powder from entering between the outer wall of the rubber bladder 3 and the inner wall of the spherical outer shell 2 when the connection point between the rubber bladder 3 and the conveying pipe 1 is closed, thus affecting the seal of the rubber bladder 3. The second notch ensures that the high-pressure gas in the backflush pipe 6 enters the interior of the spherical outer shell 2 and is blown towards the rubber bladder 3.
[0031] In one possible implementation, the second sealing gasket 23 is provided with an inner groove, and a protrusion 31 matching the inner groove is fixedly connected to the outer wall of the rubber bladder 3. The protrusion 31 is fixed to the outer wall of the rubber bladder 3 by adhesive bonding, and the protrusion 31 can be locked in the inner groove. When the rubber bladder 3 is inflated, the connection point between the spherical outer shell 2 and the conveying pipe 1 is closed, and the protrusion 31 on the rubber bladder 3 is locked in the inner groove. The cooperation between the protrusion 31 and the inner groove can further prevent aluminum ash powder from entering between the outer wall of the rubber bladder 3 and the inner wall of the spherical outer shell 2, thereby improving the sealing performance of the rubber bladder 3.
[0032] In one possible implementation, the spherical outer shell 2 has two openings facing each other, and each opening is provided with a first flange. The conveying pipe 1 has a notch, and the notch is provided with two second flanges. The first flanges and the second flanges are fixedly connected by bolts. The spherical outer shell 2 and the conveying pipe 1 are connected and communicate with each other through the first flanges and the second flanges. The rubber bladder 3 opens or closes the connection point between the spherical outer shell 2 and the conveying pipe 1, which is also the opening or closing of the connection point between the first flanges and the second flanges.
[0033] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
