Description

Technical Field

[0001] The utility model relates to the field of pneumatic conveying, in particular to a tank pneumatic conveying system. Background Art

[0002] Pneumatic conveying systems utilize the energy of airflow to transport granular materials along the airflow within a closed pipeline. This system features a simple structure and easy operation. It can convey materials horizontally, vertically, or at an angle, while also performing physical operations such as heating, cooling, drying, and airflow classification, as well as certain chemical operations.

[0003] During the transport process in pneumatic conveying systems, particulate matter can easily become stuck or adhere to the pipes, leading to blockage. This phenomenon often occurs when the air source pressure is low or the air volume is insufficient. Ash remaining in the pipes is not blown away, leading to re-feeding, resulting in an overabundance of material in the pipes, making it impossible for subsequent high-pressure air to blow away the accumulated material. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a tank pneumatic conveying system, which aims to solve the problem of pipeline blockage in the existing pneumatic conveying system.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a tank pneumatic conveying system, comprising a storage tank, and a feeding pipe fixedly connected to the top of the storage tank, a connecting valve pipe fixedly connected to the bottom of the storage tank, a stacking bin installed at the bottom of the connecting valve pipe and a pneumatic conveying pipe installed at the bottom of the stacking bin, a pushing assembly is provided inside the stacking bin, and a drainage assembly is provided inside the stacking bin.

[0007] The pushing assembly includes a round rod, a sleeve and a rotating plate. The round rod is fixedly connected to the inside of the material stacking bin, the sleeve is installed inside the material stacking bin, and the rotating plate is installed inside the material stacking bin.

[0008] The rotating plate is composed of an outer plate, an adjusting plate and a spring. The outer plate is fixedly connected to the outer wall of the sleeve. The adjusting plate is installed on the outer wall of the outer plate. The spring is fixedly connected to the outer wall of the outer plate.

[0009] Preferably, the round rod passes through the sleeve and extends to the outside of the sleeve, and the outer wall of the round rod is slidably connected to the inner wall of the sleeve.

[0010] By adopting the above technical solution, the sleeve can rotate on the outer wall of the round rod.

[0011] Preferably, the rotating plates are evenly distributed on the outer wall of the sleeve, and the outer wall of the rotating plates contacts the inner wall of the material storage bin.

[0012] By adopting the above technical solution, the materials inside the silo can be separated under the action of the rotating plate, avoiding too much material being transported at the same time, resulting in insufficient high-pressure air pressure and pipeline blockage.

[0013] Preferably, one side of the outer plate passes through the adjustment plate and extends to the inside of the adjustment plate, the outer wall of the outer plate is slidably connected to the inner wall of the adjustment plate, and the side of the spring away from the outer plate is fixedly connected to the inner wall of the adjustment plate.

[0014] By adopting the above technical solution, the adjustment plate can move on the outer wall of the outer plate, and the spring can push the adjustment plate to move.

[0015] Preferably, the drainage assembly includes an inclined plate, a rotating rod, a back plate, a swinging plate and an outer shell, the inclined plate is installed inside the material stacking bin, the rotating rod is fixedly connected to the inside of the material stacking bin, the back plate is fixedly connected to the inside of the material stacking bin, the swinging plate is installed inside the material stacking bin, and the outer shell is slidably connected to the outer wall of the swinging plate.

[0016] Preferably, the bottom of the inclined plate contacts the outer wall of the rotating plate, and the rotating rod passes through the inclined plate and is rotatably connected to the inclined plate.

[0017] By adopting the above technical solution, the inclined plate will swing around the rotating rod under the action of the rotating plate.

[0018] Preferably, the swing plate is rotatably connected to the stacking bin, and the bottom of the shell abuts against the top of the inclined plate.

[0019] By adopting the above technical solution, the swing plate can rotate inside the stacking bin. When the inclined plate shakes, the outer shell will move on the surface of the inclined plate, thereby assisting the inclined plate in unloading.

[0020] The beneficial effects of the utility model are:

[0021] 1. By setting a rotating plate, when the external high-pressure air is transported to the inside of the stacking bin through the pneumatic conveying pipe, it will push the rotating plate to rotate. The rotating plate can separate the materials transported to the inside of the stacking bin, so that the gas inside the pneumatic conveying pipe can transport a small amount of materials at the same time, thereby avoiding material accumulation, resulting in insufficient air pressure, and making it impossible for high-pressure air to push the material to flow. At the same time, when the rotating plate rotates under the action of high-pressure air, it can push the material inside the pneumatic conveying pipe to flow, further avoiding the accumulation of materials inside the pneumatic conveying pipe and the inability to flow; solving the problem of pipeline blockage in the existing pneumatic conveying system.

[0022] 2. By setting the inclined plate and the back plate, when the rotating plate rotates under the action of high-pressure air, the inclined plate can be pushed to rotate and shake around the rotating rod, so that the material accumulated on the top of the inclined plate can be transported under the action of the shaking inclined plate. At the same time, the existence of the back plate can support the inclined plate after the rotating plate is separated from the inclined plate, avoiding the inclined plate from being seriously tilted under the action of the material, resulting in the inability to achieve the gravitational effect of the inclined plate.

A pushing assembly 6 is provided inside the stacking bin 4, and a drainage assembly 7 is provided inside the stacking bin 4.

[0032] The pushing assembly 6 includes a round rod 601, a sleeve 602 and a rotating plate 603. The round rod 601 is fixedly connected to the inside of the material stacking bin 4, the sleeve 602 is installed inside the material stacking bin 4, the round rod 601 passes through the sleeve 602 and extends to the outside of the sleeve 602. The outer wall of the round rod 601 is slidably connected to the inner wall of the sleeve 602, and the sleeve 602 can rotate on the outer wall of the round rod 601. The rotating plate 603 is installed inside the material stacking bin 4. The rotating plates 603 are evenly distributed on the outer wall of the sleeve 602. The outer wall of the rotating plate 603 contacts the inner wall of the material stacking bin 4. The material inside the material stacking bin 4 can be separated under the action of the rotating plate 603 to avoid too much material being transported at the same time, resulting in insufficient high-pressure air pressure and pipeline blockage.

[0033] The rotating plate 603 consists of an outer plate 6031, an adjusting plate 6032 and a spring 6033. The outer plate 6031 is fixedly connected to the outer wall of the sleeve 602, and the adjusting plate 6032 is installed on the outer wall of the outer plate 6031. One side of the outer plate 6031 passes through the adjusting plate 6032 and extends to the interior of the adjusting plate 6032. The outer wall of the outer plate 6031 is slidably connected to the inner wall of the adjusting plate 6032 passed through, and the adjusting plate 6032 can move on the outer wall of the outer plate 6031. The spring 6033 is fixedly connected to the outer wall of the outer plate 6031, and the side of the spring 6033 away from the outer plate 6031 is fixedly connected to the inner wall of the adjusting plate 6032. The spring 6033 can push the adjusting plate 6032 to move.

[0034] By setting up the rotating plate 603, when the external high-pressure air is transported to the inside of the stacking bin 4 through the pneumatic conveying pipe 5, the rotating plate 603 will be pushed to rotate. The rotating plate 603 can separate the materials transported to the inside of the stacking bin 4, so that the gas inside the pneumatic conveying pipe 5 can transport a small amount of materials at the same time, thereby avoiding the accumulation of materials, resulting in insufficient air pressure, and making it impossible for the high-pressure air to push the materials to flow. At the same time, when the rotating plate 603 rotates under the action of the high-pressure air, it can push the materials inside the pneumatic conveying pipe 5 to flow, further avoiding the accumulation of materials inside the pneumatic conveying pipe 5 and the inability to flow; solving the problem of pipeline blockage in the existing pneumatic conveying system.

[0035] The drainage assembly 7 includes an inclined plate 701, a rotating rod 702, a counter plate 703, a swing plate 704 and a shell 705. The inclined plate 701 is installed inside the stacking bin 4, and the bottom of the inclined plate 701 contacts the outer wall of the rotating plate 603. The rotating rod 702 is fixedly connected to the inside of the stacking bin 4. The rotating rod 702 passes through the inclined plate 701 and is rotatably connected to the inclined plate 701. Under the action of the rotating plate 603, the inclined plate 701 will rock around the rotating rod 702.

The shell 705 is slidably connected to the outer wall of the swing plate 704, and the bottom of the shell 705 abuts against the top of the inclined plate 701. When the inclined plate 701 rocks, the shell 705 will move on the surface of the inclined plate 701, thereby assisting the inclined plate 701 to unload.

[0036] By setting the inclined plate 701 and the support plate 703, when the rotating plate 603 rotates under the action of high-pressure air, the inclined plate 701 can be pushed to rotate and shake around the rotating rod 702, so that the material accumulated on the top of the inclined plate 701 is transported under the action of the shaking inclined plate 701. At the same time, the existence of the support plate 703 can support the inclined plate 701 after the rotating plate 603 is separated from the inclined plate 701, thereby preventing the inclined plate 701 from being seriously tilted under the action of the material, resulting in the inability to achieve the gravitational effect of the inclined plate 701.

[0037] The working principle of this tank pneumatic conveying system is as follows: the material is conveyed to the interior of the storage tank 1 through the feed pipe 2, and the material is conveyed to the interior of the stacking bin 4 through the connecting valve pipe 3. At this time, the high-pressure gas pushes the rotating plate 603 to rotate through the pneumatic conveying pipe 5. At this time, the material flowing into the stacking bin 4 will flow under the action of the inclined plate 701 and be separated under the action of the rotating plate 603. When the rotating plate 603 rotates, the separated material will be conveyed to the interior of the pneumatic conveying pipe 5 and transported under the action of the high-pressure gas inside the pneumatic conveying pipe 5.
