[0031] In some embodiments, the dangerous powders may include lithium sulfide, lithium hexafluorophosphate, etc.

[0032] In other embodiments, the powder storage and transportation device of the present application can also be used to store and transport conventional powders. Such as: flour, fly ash, cement, etc.

[0033] Figure 3 is Figure 2 a sectional view of the structure shown in

[0034] Refer to Figures 1 to 3 , for the convenience of understanding and description, taking the state of the powder storage and transportation device during use as a reference, the up and down directions of the powder storage and transportation device are defined as the up and down directions in the following text.

[0035] Figure 4 is Figure 3 an enlarged view of the structure at position A of the structure shown in Figure 5 is Figure 2 a partial sectional view of the structure shown in Figure 6 is Figure 2 a schematic diagram of the structure after removing the cylinder body and its related structures of the structure shown in

[0036] Refer to Figures 1 to 6, this application provides a powder storage and transportation device (hereinafter referred to as the storage and transportation device), which includes a tank body 100, a conical hopper structure 200, and an air inlet structure 500. The tank body 100 extends along a horizontal direction. An accommodation space 110 is provided inside the tank body 100, and the accommodation space 110 can accommodate powder for the storage and transportation of the powder. The conical hopper structure 200 is accommodated inside the accommodation space 110. The conical hopper structure 200 includes a connecting cylinder section 210, a bottom sealing plate 220, and a discharge conical hopper 230. The connecting cylinder section 210 extends in the up and down direction to penetrate the bottom wall of the tank body 100. The bottom sealing plate 220 is sealingly connected to the bottom end of the connecting cylinder section 210. In the direction from top to bottom, the cross-sectional area of the bottom sealing plate 220 gradually decreases, and a first discharge port 221 is provided at the bottom of the bottom sealing plate 220. In the direction from top to bottom, the cross-sectional area of the discharge conical hopper 230 gradually decreases. The upper end of the discharge conical hopper 230 is sealingly connected to the inner peripheral wall of the tank body 100. The lower end of the discharge conical hopper 230 extends into the connecting cylinder section 210. The lower end of the discharge conical hopper 230 has a second discharge port 2321. The lower end of the discharge conical hopper 230 is spaced from the bottom sealing plate 220 to form an air outlet 241. An air outlet cavity 240 is formed between the outer peripheral wall of the discharge conical hopper 230, the connecting cylinder section 210, and the bottom sealing plate 220. The air inlet structure 500 is provided outside the tank body 100, and the air outlet end of the air inlet structure 500 is communicated with the air outlet cavity 240. The air inlet structure 500 is used to connect to an external compressed air source to be able to input the compressed gas in the compressed air source into the air outlet cavity 240.

[0037] When the powder storage and transportation device transports the powder to the destination and needs to unload the powder, the air inlet structure 500 connects to an external compressed air source to input the compressed gas into the air outlet cavity 240. The compressed gas in the air outlet cavity 240 blows the powder through the air outlet 241. The powder in the tank body 100 is output to the outside through the first discharge port 221 under the action of its own gravity and the kinetic energy of the compressed gas, thereby effectively improving the unloading efficiency of the powder.

[0038] Moreover, when the powder unloading is completed, the compressed gas can purge the bottom end of the bottom sealing plate 220, effectively avoiding the powder residue on the bottom sealing plate 220, thereby increasing the fluidization effect of the powder and reducing the unloading residue rate of the storage and transportation device when transporting dangerous powder. It avoids the residual dangerous powder in the tank body 100 from contacting and reacting with air and water vapor, prevents the powder from decomposing into toxic and harmful substances, and ensures the life, health, and safety of the staff and environmental safety.

[0039] Refer to Figures 1 to 3 、 Figure 5 、 Figure 6 , in this embodiment, the tank body 100 may include a cylindrical body 101 and two end head covers 102. The cylindrical body 101 extends along a horizontal direction, and the two end head covers 102 are sealingly connected to both ends of the cylindrical body 101 to ensure the airtightness of the tank body 100.

[0040] In some embodiments, the tank body 100 is further provided with structures such as a feed inlet, a feed valve, a manhole, a manhole valve, etc., which can be set with reference to the general structure of relevant powder storage and transportation tanks.

[0041] Refer to Figures 3 to 6 , in this embodiment, a receiving space 110 is defined inside the tank body 100. The discharge hopper 230 divides the receiving space 110 into a powder storage and transportation chamber 111 and a pressure maintaining chamber 112 in the vertical direction. The powder storage and transportation chamber 111 is located above the discharge hopper 230 for accommodating powder. The pressure maintaining chamber 112 is located below the discharge hopper 230.

[0042] When the powder storage and transportation equipment loads powder, the powder enters the powder storage and transportation chamber 111 through the feed inlet on the tank body 100 to ensure the loading efficiency of the powder. After the powder enters the powder storage and transportation chamber 111, it can be stored in the tank body 100 and can move along with the transportation of the tank body 100.

[0043] When the powder storage and transportation equipment unloads powder, the powder in the powder storage and transportation chamber 111 can be discharged through the discharge hopper 230.

[0044] In some embodiments, heat insulation structures, strengthening structures, etc. can be provided inside and outside the tank body 100 to improve the heat insulation performance and structural strength of the tank body 100. In other embodiments, a heat insulation layer can be coated on the outside of the tank body 100. A reinforcing ring can be provided outside the tank body 100.

[0045] Refer to Figures 2 to 6 , in this embodiment, a pressurized air inlet is defined on the tank body 100 relative to the powder storage and transportation chamber 111. A pressure maintaining air inlet is defined on the tank body 100 relative to the pressure maintaining chamber 112.

[0046] Refer to Figures 3 to 6 , in this embodiment, the hopper structure 200 is received in the receiving space 110 to be able to carry powder. And when the storage and transportation equipment unloads powder, the hopper structure 200 can assist in unloading the powder, improve the unloading efficiency of the powder, prevent the powder from contacting the outside world during unloading, reduce the residual rate of powder unloading, and ensure the safety of the staff.

[0047] The hopper structure 200 includes a connecting cylinder section 210, a bottom sealing plate 220, and a discharge hopper 230. The connecting cylinder section 210 extends in the vertical direction to penetrate through the bottom wall of the tank body 100. The outer periphery of the connecting cylinder section 210 is tightly connected to the tank body 100 to ensure the airtightness of the tank body 100.

[0048] In some embodiments, the connecting cylinder section 210 is welded to the tank body 100.

[0049] Refer to Figures 3 to 6, in this embodiment, in the direction from top to bottom, the cross-sectional area of the connecting barrel section 210 gradually decreases, so as to effectively improve the connection strength and reliability between the connecting barrel section 210 and the tank body 100, and prevent the connecting barrel section 210 from disengaging from the tank body 100.

[0050] Refer to Figures 3 to 6 , in this embodiment, a barrel inlet 211 is provided on the circumferential side wall of the connecting barrel section 210 opposite to the air outlet cavity 240. The barrel inlet 211 is connected to an external compressed air source through an air inlet structure 500, so as to be able to input compressed gas into the air outlet cavity 240.

[0051] In the direction towards the axis of the connecting barrel section 210, the cross-sectional area of the air outlet cavity 240 can be gradually reduced, so that after the compressed gas diffuses in the air outlet cavity 240, it is gradually compressed and output through the air outlet 241, thereby increasing the flow rate of the gas output from the air outlet 241, improving the purging efficiency of the gas, and ensuring the fluidized discharging efficiency and purging quality of the powder.

[0052] Refer to Figures 3 to 6 , in this embodiment, the upper end of the connecting barrel section 210 is arranged close to the bottom of the tank body 100, so as to reduce the taper of the discharge hopper 230, improve the fluidity of the powder on the upper side of the discharge hopper 230, and reduce the discharging residue rate on the discharge hopper 230.

[0053] Refer to Figures 3 to 6 , in this embodiment, the bottom sealing plate 220 is arranged at the bottom end of the connecting barrel section 210. In the direction from top to bottom, the cross-sectional area of the bottom sealing plate 220 gradually decreases, and a first discharge port 221 is opened at the bottom of the bottom sealing plate 220. The powder in the powder storage and transportation cavity 111 can be discharged to the outside of the tank body 100 through the first discharge port 221 in the bottom sealing plate 220. Moreover, the inclined bottom sealing plate 220 can improve the fluidity of the powder and reduce the discharging residue rate of the powder.

[0054] In some embodiments, the axis of the bottom sealing plate 220 is coaxially arranged with the axis of the connecting barrel section 210, so as to facilitate the powder to converge in the middle of the bottom sealing plate 220 and be output to the outside of the tank body 100 through the first discharge port 221.

[0055] In some embodiments, the bottom sealing plate 220 is welded to the connecting barrel section 210.

[0056] In other embodiments, the bottom sealing plate 220 is received in the connecting barrel section 210 and welded to the inner circumferential wall of the connecting barrel section 210, so that the bottom sealing plate 220 can be adapted to the structure of the connecting barrel section 210, prevent the bottom sealing plate 220 from disengaging from the connecting barrel section 210, and improve the connection strength between the bottom sealing plate 220 and the connecting barrel section 210.

[0057] In some embodiments, the bottom sealing plate 220 may include a spherical crown head, a frustum head, a straw hat head, etc. In other embodiments, the bottom sealing plate 220 may further include a bottom cover to seal the connection between the bottom sealing plate 220 and the connecting barrel section 210, and in the direction from top to bottom, the cross-sectional area of the bottom sealing plate 220 gradually decreases.

[0058] Refer to Figures 3 to 6 , in this embodiment, the discharge hopper 230 is accommodated in the accommodation space 110 of the tank body 100. In the direction from top to bottom, the cross-sectional area of the discharge hopper 230 gradually decreases. The upper end of the discharge hopper 230 is hermetically connected to the inner peripheral wall of the tank body 100, so that the discharge hopper 230 can divide the accommodation space 110 into a powder storage and transportation chamber 111 and a pressure maintaining chamber 112. The lower end of the discharge hopper 230 extends into the connecting barrel section 210. The lower end of the discharge hopper 230 has a second discharge port 2321.

[0059] When the storage and transportation equipment loads powder, the powder enters the powder storage and transportation chamber 111 through the feed port and accumulates on the discharge hopper 230. The inclined discharge hopper 230 can improve the fluidity of the powder while ensuring the powder transportation volume.

[0060] When the storage and transportation equipment unloads, the powder on the discharge hopper 230 can, under the action of the inclined discharge hopper 230, pass through the second discharge port 2321 and the first discharge port 221 in sequence and be output outside the tank body 100, so as to avoid powder residue on the discharge hopper 230, reduce the powder unloading residue rate, thereby avoiding material waste, reducing the cleaning cost of the tank body after unloading, avoiding long-term attachment of residual powder to corrode the tank body, avoiding powder blockage of the unloading pipeline and valve, and avoiding the formation of a dust environment in the tank body by residual powder resulting in dust explosion.

[0061] In some embodiments, the diameter of the second discharge port 2321 is larger than that of the first discharge port 221. When the airflow output from the air outlet 241 is large enough, the airflow will cause the powder at the bottom of the accommodation space 110 to expand, suspend, and generate bubbles, so that the powder in the accommodation space 110 reaches bubbling fluidization, thereby increasing the unloading efficiency, stability, and reliability.

[0062] In some embodiments, the axis of the first discharge port 221 is coaxial with the axis of the second discharge port 2321, so that the powder output from the second discharge port 2321 can be quickly output outside the tank body 100 through the first discharge port 221. Moreover, it is also convenient for the air outlet 241 to blow the powder output from the second discharge port 2321, improving the fluidization efficiency and unloading speed of the powder and reducing the unloading residue rate on the bottom sealing plate 220.

[0063] Refer to Figure 3 , Figure 4, in this embodiment, the angle between the discharge hopper 230 and the horizontal plane is greater than the angle of repose of the powder material, so as to ensure that the powder material can flow out of the tank body 100 smoothly under the action of the discharge hopper 230, avoid powder blockage, and reduce the residual rate of powder unloading.

[0064] In some embodiments, in the plane where the axis of the discharge hopper 230 is located, the angle between the tangent line at any point on the discharge hopper 230 and the horizontal plane is greater than the angle of repose of the powder material, so as to ensure the fluidity of the powder material, facilitate the unloading of the powder material, and reduce the participation rate of powder unloading.

[0065] Refer to Figures 3 to 6 , in this embodiment, the outer periphery of the discharge hopper 230 is hermetically connected to the upper end of the connecting barrel section 210, so as to improve the structural strength of the hopper structure 200 while ensuring the airtightness between the discharge hopper 230 and the connecting barrel section 210, so that the pressure maintaining cavity 112 and the air outlet cavity 240 are separated.

[0066] Refer to Figures 3 to 6 , in this embodiment, the lower end of the discharge hopper 230 is spaced from the bottom sealing plate 220 to form an air outlet 241. An air outlet cavity 240 is formed among the outer peripheral wall of the discharge hopper 230, the connecting barrel section 210 and the bottom sealing plate 220. Compressed gas in the external compressed gas source can enter the air outlet cavity 240 through the barrel section air inlet 211, and after diffusing in the air outlet cavity 240, it blows the powder material through the air outlet 241. On the one hand, the gas output from the air outlet 241 can effectively improve the unloading efficiency of the powder material and reduce the time cost; on the other hand, the gas output from the air outlet 241 can blow the powder material at the bottom of the bottom sealing plate 220, avoid too much residual powder material at the bottom of the bottom sealing plate 220, and reduce the unloading residual rate.

[0067] The air outlet cavity 240 is annular. The air outlet 241 between the bottom end of the discharge hopper 230 and the bottom sealing plate 220 is annular. When the air inlet structure 500 inputs compressed gas into the air outlet cavity 240, the compressed gas diffuses in the air outlet cavity 240 along the annular shape to fill the air outlet cavity 240. The gas in the air outlet cavity 240 is then output through the annular air outlet 241, so that the gas output from the air outlet 241 blows the powder material in an annular shape, so that the powder material on the bottom sealing plate 220 can be quickly output through the first discharge port 221. And after the powder material is output, the residual powder material on the bottom sealing plate 220 can be reduced, and the unloading residual rate of the powder material can be reduced.

[0068] Refer to Figures 3 to 6, in this embodiment, in the direction towards the axis of the first discharge port 221, the distance between the bottom sealing plate 220 and the discharge hopper 230 gradually decreases. After the compressed gas diffuses in the air outlet cavity 240, the gas can flow towards the air outlet 241 in the air outlet cavity 240. According to Bernoulli's law, after the compressed gas flows towards the air outlet 241 in the air outlet cavity 240, the gas velocity output from the air outlet 241 increases, so as to facilitate the gas to impact the powder material, and after mixing with the powder material, it is output to the outside of the tank body 100 through the first discharge port 221, thereby effectively improving the unloading efficiency of the powder material and avoiding the residual powder material on the bottom sealing plate 220.

[0069] In some embodiments, the discharge hopper 230 includes a first hopper part 231 and a second hopper part 232. The first hopper part 231 is located above the second hopper part 232. The upper end of the first hopper part 231 is hermetically connected to the inner peripheral wall of the tank body 100. The second hopper part 232 is located within the connecting barrel section 210. The upper end of the second hopper part 232 is hermetically connected to the lower end of the first hopper part 231, so as to facilitate the powder material to enter the second hopper part 232 from the first hopper part 231.

[0070] In some other embodiments, there is a smooth transition between the first hopper part 231 and the second hopper part 232.

[0071] In some other embodiments, the connection part between the first hopper part 231 and the second hopper part 232 is also hermetically connected to the upper end of the connecting barrel section 210, thereby improving the structural strength and reliability of the hopper structure 200.

[0072] In some other embodiments, the upper end of the connecting barrel section 210 can be hermetically connected to the outer periphery of the first hopper part 231 or the second hopper part 232.

[0073] In some other embodiments, the first hopper part 231 and the second hopper part 232 are integrally formed.

[0074] In some embodiments, the axis of the first hopper part 231 is coaxially arranged with the axis of the second hopper part 232.

[0075] Refer to Figures 3 to 6 , in this embodiment, the storage and transportation equipment includes a plurality of hopper structures 200. The plurality of hopper structures 200 are arranged in sequence along the axial direction of the tank body 100. The opposite sides of the upper ends of the plurality of discharge hoppers 230 are hermetically connected, and the outer peripheries of the upper ends of the plurality of discharge hoppers 230 are closely connected to the inner peripheral wall of the tank body 100, so as to divide the accommodation space 110 into an upper powder storage and transportation cavity 111 and a lower pressure maintaining cavity 112.

[0076] Refer to Figures 3 to 6, in this embodiment, the upper end of the discharge hopper 230 is arc-shaped and transitions smoothly with the inner wall of the tank body 100 to reduce the residual amount of powder at the gap between the discharge hopper 230 and the inner wall of the tank body 100.

[0077] Refer to Figures 5 to 6 , in this embodiment, a plurality of partition plates 310 are arranged in the tank body 100. The partition plates 310 are located between adjacent two hopper structures 200. The partition plates 310 extend in an arc shape along the circumferential direction of the tank body 100. The inner circumference of the partition plates 310 is connected to the facing sides of adjacent two discharge hoppers 230, and the outer circumference of the partition plates 310 is connected to a part of the inner circumferential wall of the tank body 100 relative to the pressure-holding cavity 112. The partition plates 310 can effectively improve the support for the hopper structure 200, thereby effectively ensuring the structural strength and stability of the storage and transportation equipment.

[0078] In some embodiments, at least one ventilation hole 311 is provided on a part of the partition plates 310 located in the pressure-holding cavity 112 to connect the part of the pressure-holding cavity 112 on both sides of the partition plates 310, ensuring uniform pressure everywhere in the pressure-holding cavity 112 and improving the structural strength and stability of the storage and transportation equipment.

[0079] Refer to Figure 5 and Figure 6 , in this embodiment, the inner circumference of the partition plates 310 extends beyond the hopper structure 200. Adjacent two discharge hoppers 230 are respectively located on both sides of the partition plates 310 and are tightly connected to both sides of the partition plates 310.

[0080] In some embodiments, the facing sides of adjacent two discharge hoppers 230 are welded to the partition plates 310 to ensure the connection strength and reliability between the discharge hoppers 230 and the partition plates 310.

[0081] Refer to Figures 1 to 3 , Figure 5 , Figure 6 , in this embodiment, the storage and transportation equipment further includes a discharge main pipe 400. The discharge main pipe 400 is located below all the hopper structures 200 and extends along the axial direction of the tank body 100. The discharge main pipe 400 can communicate with the powder storage and transportation cavity 111 through a plurality of first discharge ports 221, so that the powder in the powder storage and transportation cavity 111 can be respectively output into the discharge main pipe 400 through a plurality of hopper structures 200 and discharged outside the storage and transportation equipment through the discharge main pipe 400.

[0082] In some embodiments, a discharge valve is provided between the discharge main pipe 400 and the bottom sealing plate 220 to control the unloading of the powder in the powder storage and transportation cavity 111 into the discharge main pipe 400 and improve the unloading efficiency of the powder.

[0083] Refer to Figures 1 to 4, in this embodiment, the storage and transportation device further includes an air inlet structure 500. The air inlet structure 500 includes a first air inlet pipe 510. The air inlet end of the first air inlet pipe 510 can be connected to an external compressed air source, and the air outlet end of the first air inlet pipe 510 is connected to a barrel joint air inlet 211 on the connecting barrel section 210 for inputting compressed gas in the external compressed air source into the air outlet cavity 240. The compressed gas in the air outlet cavity 240 can blow the powder through the air outlet 241. On the one hand, it can accelerate the unloading speed of the powder and reduce the time cost of powder unloading; on the other hand, it can blow the bottom sealing plate 220 after the powder unloading is completed to reduce the residual rate of powder unloading.

[0084] In some embodiments, there are multiple first air inlet pipes 510, and the multiple first air inlet pipes 510 are respectively arranged corresponding to multiple hopper structures 200, so that the compressed gas in the compressed air source can correspondingly enter the air outlet cavities 240 in the multiple hopper structures 200, thereby facilitating the compressed gas to blow the powder at multiple hopper structures 200 respectively.

[0085] In some embodiments, the type of gas in the compressed air source can be processed according to the type of powder. When the powder is a conventional powder, such as flour, cement, etc., the compressed gas can be compressed air.

[0086] In some embodiments, when the powder is a high-risk powder, such as lithium sulfide, lithium hexafluorophosphate, the compressed gas can be compressed nitrogen to prevent lithium sulfide and lithium hexafluorophosphate from contacting with moisture and reacting. In other embodiments, the compressed gas can also be an inert gas to prevent the powder from contacting with moisture and reacting.

[0087] In some embodiments, the compressed air source can also be connected to the outside of the tank body 100 to move with the tank body 100. That is, the storage and transportation device has an in-built compressed air source, which is input into the tank body 100, the hopper structure 200 and the discharge main pipe 400 through the air inlet structure 500.

[0088] Refer to Figures 1 to 4 , in this embodiment, the air inlet structure 500 further includes a second air inlet pipe 520. The air inlet end of the second air inlet pipe 520 is connected to the compressed air source, and the air outlet end of the second air inlet pipe 520 is connected to the powder storage and transportation cavity 111 through a pressurized air inlet to input compressed gas into the powder storage and transportation cavity 111. When the powder is unloaded, the second air inlet pipe 520 inputs the compressed gas in the compressed air source into the powder storage and transportation cavity 111. After the compressed gas enters the powder storage and transportation cavity 111, it presses on the powder to prevent the powder storage and transportation cavity 111 from having a negative pressure, assisting the powder to be quickly unloaded and improving the unloading efficiency of the powder. Moreover, the compressed gas input into the powder storage and transportation cavity 111 can also protect the powder, preventing the powder in the powder storage and transportation cavity 111 from contacting the air and ensuring the safety and reliability of the powder.

[0089] See also Figures 1 to 4 In this embodiment, the air intake structure 500 also includes a third air intake pipe 530, the air intake end of the third air intake pipe 530 is connected to the compressed air source, and the air outlet end of the third air intake pipe 530 is connected to the pressure maintaining chamber 112 through the pressure maintaining air inlet to input compressed gas into the pressure maintaining chamber 112.

[0090] When the powder is being discharged, the second air inlet pipe 520 inputs compressed gas into the powder storage and transportation chamber 111, and the compressed gas applies pressure to the powder to ensure that the powder is quickly discharged. When the compressed gas applies pressure to the powder, the powder is pressed on the discharge cone hopper 230. At this time, the third air inlet pipe 530 inputs compressed gas into the pressure-maintaining chamber 112, and the compressed gas input by the third air inlet pipe 530 applies pressure to the discharge cone hopper 230.

[0091] The pressure applied by the compressed gas in the pressure-maintaining chamber 112 to the discharge cone hopper 230 is the same as the pressure applied by the compressed gas in the powder storage and transportation chamber 111 to the discharge cone hopper 230, so that the accommodating space 110 in the tank body 100 forms a pressure balance as a whole. The discharge cone hopper 230 is not subjected to the internal pressure but only to the weight of the powder, thereby avoiding distortion of the connection between the discharge cone hopper 230 and the tank body 100, thereby effectively protecting the discharge cone hopper 230 and improving the structural strength and carrying capacity of the storage and transportation equipment.

[0092] Furthermore, the provision of the powder storage and transportation chamber 111 and the pressure-maintaining chamber 112 can reduce the thickness of the discharge cone hopper 230 while ensuring the structural strength of the discharge cone hopper 230 , thereby reducing the weight of the storage and transportation equipment and reducing the production cost of the storage and transportation equipment.

[0093] See also Figures 1 to 4 In this embodiment, the air intake structure 500 further includes a fourth air intake pipe 540 , and the air outlet end of the fourth air intake pipe 540 is connected to one end of the discharge main pipe 400 to input the compressed gas into the discharge main pipe 400 .

[0094] When the powder is unloading, the powder in the powder storage and transportation chamber 111 passes through the second discharge port 2321 and the first discharge port 221 and then enters the discharge main pipe 400. The fourth air inlet pipe 540 inputs the compressed gas in the compressed gas source into the discharge main pipe 400 to push the powder to move in the discharge main pipe 400. In addition, the compressed gas output by the fourth air inlet pipe 540 can purge the powder in the discharge main pipe 400 to prevent the powder from remaining in the discharge main pipe 400, reduce the unloading residual rate of the storage and transportation equipment, thereby preventing the powder from contacting with the air and reacting, and protecting the life, health and safety of the staff.

[0095] In some embodiments, valves are provided on the first intake pipe 510, the second intake pipe 520, the third intake pipe 530, and the fourth intake pipe 540 to be able to control the on-off states of the first intake pipe 510, the second intake pipe 520, the third intake pipe 530, and the fourth intake pipe 540, thereby facilitating the staff to control the storage and transportation equipment.

[0096] In some other embodiments, the valve can be a pneumatic valve, an electric valve, or a manual valve.

[0097] In some embodiments, the intake ends of the first intake pipe 510, the second intake pipe 520, the third intake pipe 530, and the fourth intake pipe 540 are connected and communicated to simplify the intake structure 500 and reduce the production cost of the intake structure 500.

[0098] In this embodiment, the storage and transportation equipment may further include a frame 600. The frame 600 is disposed outside the tank body 100 and connected to the tank body 100 to support the tank body 100, thereby facilitating the placement and transportation of the tank body 100.

[0099] In some embodiments, the structure of the frame 600 may refer to the frame structure of an existing tank container to facilitate the transportation and stacking of the storage and transportation equipment.

[0100] In some embodiments, the storage and transportation equipment can be a storage tank structure or a tank container structure as long as it can achieve the function of storing and transporting powder materials.

[0101] In some embodiments, a pressure relief valve (not shown in the figure) may be provided on the tank body 100. When the tank body 100 is loaded with powder materials, the pressure relief valve can discharge some of the gas in the powder material storage cavity 111 and / or the pressure maintaining cavity 112, thereby facilitating the loading, transportation, and unloading of the powder materials.

[0102] In this embodiment, the storage and transportation equipment may further be provided with a walkway structure. The walkway structure is disposed on the top of the tank body 100 to facilitate the staff to move on the tank body 100. In some embodiments, the walkway structure can be connected to the frame 600.

[0103] Refer to Figures 1 to 6 , this application provides a powder material storage and transportation equipment. The powder material can enter the powder material storage cavity 111 through the feed valve and can be transported to the destination following the storage and transportation equipment.

[0104] When the powder material storage and transportation equipment reaches the destination, the first discharge port 221 is opened so that the powder material on the discharge hopper 230 is output into the discharge main pipe 400 through the second discharge port 2321 and the first discharge port 221.

[0105] When discharging the powder material, the first communication pipe, the second communication pipe, the third communication pipe and the fourth communication pipe are all opened. Part of the compressed gas in the compressed gas source can be input into the air outlet cavity 240 through the first air inlet pipe 510 and diffuse along the annular air outlet cavity 240. After the compressed gas diffuses in the air outlet cavity 240, it is output through the annular air outlet 241 to purge the powder material on the bottom sealing plate 220, thereby improving the fluidization effect and flow rate of the powder material, enabling the powder material in the tank body 100 to be quickly discharged, and improving the discharging efficiency. Moreover, it can also prevent the powder material from remaining on the bottom sealing plate 220, reduce the unloading residue rate of the powder material, and avoid the reaction of the powder material with air, which may endanger the life, health and safety of the staff.

[0106] Part of the compressed gas in the compressed gas source can be input into the powder storage and transportation cavity 111 through the second air inlet pipe 520, so that the compressed gas source can press the powder material, thereby assisting the powder material to be output to the discharge main pipe 400 through the second discharge port 2321 and the first discharge port, effectively improving the fluidization effect of the powder material and increasing the discharging efficiency of the powder material. Moreover, it can also purge the powder material on the discharge cone hopper 230, prevent the powder material from remaining on the discharge cone hopper 230, and reduce the unloading residue rate of the storage and transportation equipment.

[0107] Part of the compressed gas in the compressed gas source can be input into the pressure maintaining cavity 112 through the third air inlet pipe 530, so that the air pressure in the pressure maintaining cavity 112 is balanced with the air pressure in the powder storage and transportation cavity 111, thereby ensuring the structural strength and stability of the discharge cone hopper 230.

[0108] Part of the compressed gas in the compressed gas source can also be input into the discharge main pipe 400 through the fourth air inlet pipe 540 to push the material in the discharge main pipe 400 to move, assist in discharging the powder material, and improve the discharging efficiency. Moreover, it can also purge the powder material in the discharge main pipe 400, thereby preventing the powder material from remaining in the discharge main pipe 400 and reducing the unloading participation rate of the powder material.
