Description

Technical Field

[0001] This utility model relates to the field of dispensing tank device technology, and more specifically, to a variable pressure anti-clogging dispensing tank. Background Technology

[0002] As a key piece of equipment in pneumatic conveying systems for powder and granular materials, the variable pressure conveying tank achieves closed-loop material conveying through cyclical changes in internal pressure. Traditional anti-clogging technologies rely on airflow disturbance and structural optimization, but when handling high-viscosity, hygroscopic materials, serious problems of internal wall adhesion and clogging still exist. During dynamic conveying, such materials will continuously accumulate on the inner wall of the tank due to viscous adsorption effects, forming a dense adhesive layer.

[0003] The tank body of the delivery tank is mostly conical, and its inclined inner wall will aggravate the retention of material. The adhesion layer accumulates and thickens on the inclined wall, eventually forming a blockage at the bottom of the cone. The airflow of the existing pneumatic unblocking solution cannot effectively peel off the adhered material layer, and the traditional mechanical rapping device cannot fit the cone surface to remove dead corners due to structural limitations, resulting in frequent blockage at the bottom of the tank body, which seriously affects the continuous operation capability of the equipment.

[0004] In view of this, we propose a variable pressure anti-clogging delivery tank. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this invention is to provide a variable pressure anti-clogging delivery tank to solve the problem mentioned in the background art that material adheres to the inclined inner wall of the traditional variable pressure delivery tank, causing the tank to become clogged and affecting the processing efficiency of the device.

[0007] 2. Technical Solution

[0008] A variable pressure anti-clogging dispensing tank includes a tank body and a support for supporting the tank body. The top and bottom of the tank body are respectively provided with a feed inlet and a discharge outlet. A feed valve is provided at the feed inlet, and a discharge pipe is connected to the discharge outlet. An air inlet valve and an air outlet valve are fixedly connected to the tank body. A mounting bracket is fixedly connected to the top of the tank body. A rotating rod is rotatably connected to the mounting bracket. Multiple inclined rods are fixedly connected to the rotating rod. A rotating ring located at the discharge outlet is fixedly connected to the bottom of the rotating rod.

[0009] Preferably, a rotating block is fixedly connected to the top of the rotating rod, and a mounting block is fixedly connected to the top of the tank body. The rotating block is rotatably connected to the mounting frame.

[0011] Preferably, a sealing ring for sealing is fixedly connected at the rotatable connection between the drive rod and the mounting rod.

[0012] Preferably, the axes of the plurality of inclined rods are all parallel to the generatrix of the conical section of the inner wall of the tank, and the plurality of inclined rods overlap with the inner wall of the tank, so that when the plurality of inclined rods rotate with the rotating rod, they can peel off and remove the material adhesion layer attached to the inner wall of the tank to prevent the tank from becoming blocked.

[0013] Preferably, a connecting rod is fixedly connected to the top of each of the plurality of inclined rods, one end of the connecting rod is fixedly connected to the inclined rod, and the other end of the connecting rod is fixedly connected to the rotating rod.

[0014] Preferably, a plurality of follower rods are fixedly connected inside the rotating ring, and the plurality of follower rods are all fixedly connected to the bottom of the rotating rod. The plurality of follower rods are used to disturb the discharge port at the bottom of the tank when rotating with the rotating rod to further prevent blockage inside the tank.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model, by setting the inclined rods to fit against the inner wall of the tank, allows multiple inclined rods to form continuous scraping during rotation, directly destroying the inner wall adhesion layer of highly viscous materials, thus eliminating the problem of device blockage caused by the cone-shaped material accumulation due to scraping dead corners in traditional equipment.

[0018] 2. The rotating ring and follower rod of this utility model form a bottom disturbance structure at the discharge port and cooperate with the wall scraping action of the inclined rod. While removing the adhesive layer on the cone wall, it actively breaks the material bridging blockage at the discharge port, reduces the number of downtime maintenance caused by blockage, improves the continuous operation effect of the equipment, and thus improves the processing efficiency.

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] A variable pressure anti-clogging delivery tank includes a tank body 1 and a bracket 13 for supporting the tank body 1. The top and bottom of the tank body 1 are respectively provided with a feed inlet 11 and a discharge outlet 12. A feed valve 111 is provided at the feed inlet 11, and a discharge pipe 121 is connected to the discharge outlet 12. An air inlet valve 112 and an air outlet valve 113 are fixedly connected to the tank body 1. A mounting bracket 14 is fixedly connected to the top of the tank body 1. A rotating rod 15 is rotatably connected to the mounting bracket 14. Multiple inclined rods 6 are fixedly connected to the rotating rod 15. A rotating ring 7 located at the discharge outlet 12 is fixedly connected to the bottom of the rotating rod 15. This configuration establishes a physical anti-clogging system through the linkage structure of the rotating rod 15, the inclined rods 6, and the rotating ring 7. While retaining the traditional variable pressure function, it makes the cone wall scraping and bottom disturbance operate synchronously to prevent clogging.

[0030] In addition, a rotating block 16 is fixedly connected to the top of the rotating rod 15, and a mounting block is fixedly connected to the top of the tank body 1. The rotating block 16 is rotatably connected to the mounting frame 14. The mounting frame 14 should be located at the bottom of the feed valve 111. This arrangement can ensure the stability of the rotating rod 15.

[0031] Secondly, a mounting rod 17 is fixedly connected to the tank body 1, a drive rod 18 is rotatably connected to the mounting rod 17, a motor 19 for driving the drive rod 18 is fixedly connected to the mounting rod 17, a first bevel gear 3 is fixedly connected to the drive rod 18, a second bevel gear 4 is fixedly connected to the rotating rod 15, the first bevel gear 3 and the second bevel gear 4 are meshed, and a sealing ring 2 for sealing is fixedly connected at the rotatable connection between the drive rod 18 and the mounting rod 17. This arrangement allows the motor 19 to directly drive the rotating rod 15 to rotate when it starts, while the sealing ring 2 ensures the airtightness of the device.

[0032] Furthermore, the axes of the multiple inclined rods 6 are all parallel to the generatrix of the conical section of the inner wall of the tank 1, and the multiple inclined rods 6 overlap with the inner wall of the tank 1. This allows the multiple inclined rods 6 to peel off and remove the material adhesion layer attached to the inner wall of the tank 1 when the rotating rod 15 rotates, thus preventing the tank 1 from becoming clogged. This arrangement ensures that the multiple inclined rods 6 can generate continuous shearing force to peel off the adhesion layer when the rotating rod 15 rotates.

[0033] In addition, a connecting rod 5 is fixedly connected to the top of each of the multiple inclined rods 6. One end of the connecting rod 5 is fixedly connected to the inclined rod 6, and the other end of the connecting rod 5 is fixedly connected to the rotating rod 15. This arrangement makes the connecting rod 5 a cantilever support for the inclined rod 6. The strength of the inclined rod 6 is enhanced by the triangular stabilizing structure, preventing the long rod from bending and deforming under the resistance of viscous materials, and ensuring the uniform distribution of scraping pressure.

[0034] Furthermore, multiple follower rods 8 are fixedly connected inside the rotating ring 7. All follower rods 8 are fixedly connected to the bottom of the rotating rod 15. The multiple follower rods 8 are used to disturb the discharge port 12 at the bottom of the tank 1 when rotating with the rotating rod 15 to further prevent the tank 1 from being blocked. By forming a rotating blade structure within the frame of the rotating ring 7 through the follower rods 8, the phenomenon of material bridging and blockage at the discharge port 12 can be actively broken.

[0035] Working principle:

[0036] During the feeding stage, the feed valve 111 is opened and the vent valve 113 is opened simultaneously to depressurize the tank 1 to atmospheric pressure. The material falls into the tank through the feed inlet 11 under gravity. At this time, the vent valve 112 remains closed to prevent gas leakage. After feeding is complete, the feed valve 111 and vent valve 113 are closed to form a sealed cavity. Then, the vent valve 112 is opened to inject compressed gas into the tank, increasing the pressure to the set conveying pressure. After entering the feeding stage, the conveying valve on the discharge pipe 121 is opened. The high-pressure gas pushes the material out through the discharge pipe 121. After the material is discharged, the discharge valve and vent valve 113 are closed. 12. Open the vent valve 113 again to complete the system depressurization and prepare for the next feeding cycle. During the material feeding stage of the tank 1, the drive motor 19 is started simultaneously. The power is transmitted to the rotating rod 15 through the bevel gear set to drive it to rotate stably. The inclined rod 6 moves continuously against the wall during the rotation, forming a continuous circumferential mechanical scraping action, which effectively peels off the adhesive layer formed by the sticky material on the inclined wall. At the same time, the annular frame at the bottom of the rotating rod 15 drives multiple follower rods 8 to rotate at high speed in the area of ​​the discharge port 12, forming a dynamic paddle structure to actively destroy the material bridging and blockage.
