Description

Technical Field

[0001] The invention relates to the technical field of containers, in particular to a powder tank container. Background Art

[0002] Powder tank containers are mainly used for the transportation of powdery and granular materials such as cement, fly ash, and mineral powder. They have environmentally friendly properties such as closed transportation and pollution-free. Because they also have the characteristics of containers, they can meet the needs of multimodal transportation by road, rail, and water. At the same time, the tank body adopts pneumatic unloading method, which can realize closed loading and unloading, and meet the transportation needs of different materials at different heights.

[0003] At present, the powder tank container is composed of a tank body, an air supply system, a unloading system, a container frame and other parts. The tank body adopts a straight cylindrical structure and is divided into two compartments. Each compartment is equipped with a slide plate, an air chamber, a fluidized bed, etc. The slide plate, the air chamber and the tank body are welded and fixed, and the breathable cloth is laid on the slide plate to form a fluidized bed. The material is fluidized through the fluidized bed and then transported to the outside.

[0004] However, the existing powder tank containers still have the following shortcomings:

[0005] In order to achieve the fluidization performance of materials, the existing powder tank containers need to arrange a slide plate in the tank body. There must be gas in the tank body and an air chamber is arranged. The arrangement of the slide plate and the air chamber increases the dead weight of the tank body and reduces the volume utilization rate. In addition, many dead angles are generated between the slide plate, the air chamber and the tank body. During the unloading process, the materials in the dead angles cannot be fluidized, resulting in material residue and a large material surplus rate. After the slide plate is welded to the tank body, due to the pressure of the tank body during operation, the ratio of the space in the slide plate to the effective space of the tank body is large, and the slide plate is prone to deformation during operation, resulting in stress concentration at the welding point with the tank body, causing the weld to crack easily and the slide plate to crack.

[0006] 2. Regarding the air supply system for powder containers, each bin of the tank body is divided into front and rear parts. During the unloading process, due to the different material discharge speeds, the unloading completion time of the front and rear parts of each bin is different. It is easy for the material on the other side to remain after the unloading on one side is completed. At this time, the air chamber air supply valve cannot confirm which one is closed, and the air supply pressure is unbalanced, resulting in insufficient unloading and the need for multiple secondary unloading operations.

[0007] 3. Regarding the unloading system of the powder transport vehicle, the separate unloading is adopted, which requires the operator to observe the operation on site and wait for unloading on site, resulting in low unloading efficiency. During the unloading process, the fluidization of the material at the discharge port is affected by the influence of the breathable cloth pressure plate at the suction port, resulting in problems such as small material discharge and large gas discharge in the later stage, resulting in slow unloading speed and residual unloading. During the unloading process, it is a closed work and cannot be visualized, resulting in the inability to understand the actual situation at the later stage of unloading, resulting in low operation efficiency and requiring multiple secondary unloading operations.

[0018] The lower fixing seat is provided with an air inlet 1.

[0019] Furthermore, the elastic body includes a fixed rubber plate, on which nylon rubber is fixedly mounted by fixing bolts, and a vent is also provided in the elastic body;

[0020] The vents in the two elastic bodies are communicated with the head air chamber and the compartment air chamber respectively.

[0021] Further, the pressure compensation and balancing system of the air supply system includes a pressure balance compensation tank, the pressure balance compensation tank includes an air inlet two, and is fixedly connected with a front air intake pipe and a rear air intake pipe, one end of the front air intake pipe away from the pressure balance compensation tank is communicated with the head air chamber, and one end of the rear air intake pipe away from the pressure balance compensation tank is communicated with the compartment air chamber;

[0026] Beneficial effects of the present invention:

[0027] 1. The tank structure provided by the present invention adopts a two-point sinking structure and a trapezoidal cone structure. The docking section with the head adopts a perfect circular section, and the other end section adopts a hyperbolic arc section, which improves the pressure bearing capacity of the tank body and breaks through the problem that the material of the straight-cylinder tank body cannot accumulate at one point.

After the powder is fluidized in the rectangular fluidized bed, it gradually gathers to the lowest point of the tank, and the annular fluidized bed forms annular fluidization on the material again, which increases the material flow rate and the unloading speed. In addition, the arrangement of the annular fluidized bed can reduce the residual material at the lowest point. The annular fluidized bed forms fluidization, which makes it easier to discharge the tank and prevents material residue.

[0029] 3. The elastomer is in an uninflated state during loading, and the material fills the entire tank body; during unloading, when the air supply system inflates the tank body, it will also inflate the elastomer. As the material decreases, the elastomer will fill the entire space between the tip and the tank body after inflation, preventing the material from remaining here and solving the problem of material residue here.

[0030] 4. The setting of the pressure compensation balance system of the air supply system can effectively solve the problem of incomplete unloading on the other side caused by continued air supply after the material on one side is unloaded. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0045] Example:

[0046] See also Figures 1 to 10 In an embodiment of the present invention, a powder tank container includes a box frame 1, a tank assembly is fixedly installed in the box frame 1, a gas supply system 6 and a discharge system 7 are provided in the tank assembly, the tank assembly includes a tank body, a partition plate 16 is fixedly installed in the middle position of the tank body, two partition air chambers 14 are provided at both sides of the bottom of the partition plate 16, the tank body is divided into two identical storage bins by the partition plate 16, both ends of the tank body are trapezoidal cones 3, and both ends of the tank body are fixedly installed with a head 2, and a head air chamber 8 is provided in the head 2;

[0047] A loading port 4 is provided on the top of the storage bin, a pressure relief valve 5 is provided on the top of one storage bin, and a ladder 15 is fixedly installed on the outside of one storage bin;

[0048] A fluidized bed system is installed at the bottom of the storage bin, and a suction port 13 is fixedly installed just above the fluidized bed system;

[0049] The bottom of the storage bin is provided with elastic bodies 10 near the end cap air chamber 8 and the compartment air chamber 14;

[0050] A pressure compensation balance system for the air supply system is arranged below the storage bin.

[0051] The tank body structure adopts a two-point sinking structure and a trapezoidal cone structure. The docking section with the head 2 adopts a perfect circular section, and the other end section adopts a hyperbolic arc section, which improves the pressure-bearing capacity of the tank body and breaks through the problem that materials in a straight-cylinder tank body cannot accumulate at one point. The use of the trapezoidal cone can remove the original sliding plate structure in the tank body, forming a sliding plate-free structure, and solving the problem that traditional sliding plates are easy to open welds.

[0052] The fluidized bed system includes a rectangular fluidized bed 22 arranged at the bottom of the storage bin. The rectangular fluidized bed 22 is composed of a plurality of air-permeable belts 11. Both ends of the air-permeable belts 11 are fixedly connected with tips 9. The ends of the two tips 9 away from the air-permeable belts 11 are respectively fixedly connected to the end cap air chamber 8 and the compartment air chamber 14 in a through-type manner.

[0053] An annular fluidized bed 12 is disposed in the middle of the rectangular fluidized bed 22 .

[0054] The annular fluidized bed 12 includes an annular fluidized bed tank body connecting plate 23 located in the middle of the rectangular fluidized bed 22 and fixedly mounted on the tank body. The annular fluidized bed tank body connecting plate 23 is provided with a lower fixing seat 25. A breathable cloth 24 is fixedly mounted on the annular fluidized bed tank body connecting plate 23 through the lower fixing seat 25 and the connecting bolts 26.

[0055] An air inlet 27 is provided on the lower fixing seat 25 .

[0056] The arrangement of the rectangular fluidized bed 22 and the annular fluidized bed 12 makes the fluidized bed system a composite fluidized bed system. The composite fluidized bed can make the bottom fluidized bed cover the entire bottom of the tank body, achieving a fluidized state without dead corners. After the powder is fluidized in the rectangular fluidized bed 22, it gradually gathers to the lowest point of the tank body, and the annular fluidized bed 12 forms annular fluidization on the material again, thereby increasing the material flow rate and the unloading speed. In addition, the arrangement of the annular fluidized bed 12 can reduce the residual material at the lowest point. The annular fluidized bed 12 is fluidized to make it easier to discharge from the tank body, thereby preventing the residue of the material.

[0057] In the annular fluidized bed 12, the annular fluidized bed tank connecting plate 23 is fixed to the tank body, and then the breathable cloth 24 is fixed to the annular fluidized bed tank connecting plate 23 through the lower fixing seat 25 by the connecting bolts 26. When the tank body is unloaded, the air enters the space of the lower fixing seat 25 through the air inlet 27, and the material is fluidized by the breathable cloth 24. In addition, the annular fluidized bed 12 can be used as a sewage outlet, and sewage can be discharged in an emergency.

[0058] The elastic body 10 includes a fixed rubber plate 20, on which a nylon rubber 18 is fixedly mounted by a fixing bolt 19, and a vent 21 is also provided in the elastic body 10;

[0059] The vents 21 in the two elastic bodies 10 are communicated with the end cap air chamber 8 and the compartment air chamber 14 respectively.

[0060] There is a dead space between the tip 9 and the tank body, and the gas cannot blow directly here, causing the material to be hidden in this space, increasing the residual rate of the tank body; in the present invention, the elastomer 10 is in an uninflated state during loading, and the material fills the entire tank body; during the unloading process, when the air supply system 6 inflates the tank body, the elastomer 10 is also inflated at the same time. As the material decreases, the elastomer 10 is inflated and fills the entire space between the tip 9 and the tank body, preventing the material from remaining here, thereby solving the problem of material residue here.

[0061] Specifically, when the tank is inflated and unloaded, gas is introduced from the vent 21, and the elastomer 10 is gradually inflated and expanded. During the unloading process of the tank, the elastomer 10 is gradually inflated and expanded until it is aligned with the tip 9 and the breathable belt 11, which can reduce the residual material here and reduce the residual rate; in addition, the vent 21 of the elastomer 10 is connected to the head air chamber 8, which can maintain air pressure balance. After the unloading of the tank is completed, the gas in the elastomer 10 is discharged into the tank through the head air chamber 8, and the elastomer 10 returns to its original state after the pressure is released, ensuring that the loading volume requirement can be met when the tank is loaded.

[0062] The pressure compensation and balancing system of the air supply system includes a pressure balance compensation tank 32, the pressure balance compensation tank 32 includes an air inlet 2 33, and is fixedly connected with a front air intake pipe 28 and a rear air intake pipe 37, the end of the front air intake pipe 28 away from the pressure balance compensation tank 32 is communicated with the head air chamber 8, and the end of the rear air intake pipe 37 away from the pressure balance compensation tank 32 is communicated with the compartment air chamber 14;

[0063] The air supply system pressure compensation and balancing system also includes a control system.

[0064] The control system includes a control box 38, a front material sensor 31 and a rear material sensor 34 installed on the bottom surface of the storage bin, a front control switch 30 and a front intake pipe pressure sensor 29 installed in the front intake pipe 28, and a rear control switch 35 and a rear intake pipe pressure sensor 36 installed in the rear intake pipe 37;

[0065] The front material sensor 31 , the rear material sensor 34 , the front control switch 30 , the rear control switch 35 , the front intake pipe pressure sensor 29 , the rear intake pipe pressure sensor 36 and the control box 38 are electrically connected.

[0066] When the air supply system 6 is working, air is supplied into the tank body through the second air inlet 33, and air is supplied to the head air chamber 8 and the compartment air chamber 14 through the front air inlet pipe 28 and the rear air inlet pipe 37. When the second air inlet 33 supplies air into the tank, the gas is stored in the pressure balance compensation tank 32 as a means of adjusting the pressure balance of the front and rear air inlet pipes to ensure that there is always sufficient working pressure in the tank body; during the air supply process, the front air inlet pipe pressure sensor 29 and the rear air inlet pipe pressure sensor 36 monitor the pressure and reflect it to the control system. After receiving the signal, the control system controls the front control switch 30 and the rear control switch 35 to adjust the ventilation ratio of the second air inlet 33;

[0067] The control switch has a one-way check function to balance the air supply. The pressure balance compensation tank 32 serves as a pressure compensation device to supply air to the front and rear control switches. The front material sensor 31 and the rear material sensor 34 monitor the material status during the unloading operation in the tank and sense the remaining material status in the tank. If the material on one side has been unloaded, the control system controls the front control switch 30 and the rear control switch 35 to close the air inlet valve, which can effectively solve the problem of incomplete unloading on the other side due to continued air supply after the material on one side has been unloaded.

[0068] The storage bin is provided with reinforcing ribs 17, and the provision of the reinforcing ribs 17 improves the stability of the tank structure.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
