Technical Field
[0001] This application relates to the field of tank container technology, and more particularly to a powder tank container. Background Technology
[0002] Powder tank container unloading involves using a fluidized bed to fluidize the powder before unloading. However, powder tends to accumulate in the middle area of the fluidized bed, resulting in high powder residue, incomplete unloading, and difficult cleaning. Existing powder containers incorporate ash collection troughs to reduce residue, but the unloading effect remains unsatisfactory, with powder accumulating between adjacent feed troughs. Furthermore, most tank containers use a single air inlet pipe for single-area air intake and unloading, leading to low unloading efficiency. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention

The two ends of the lower end beam 202 are respectively connected to the corner posts 204. Each end frame 2 is provided with one saddle 8 and two saddle plates 7. The saddle 8 is disposed between the two saddle plates 7. The saddle plates 7 are connected to the end frame 2 and the cylinder 101. The saddle 8 is connected to the outer periphery of the cylinder 101. The two ends of the saddle 8 are respectively connected to the corresponding saddle plates 7. The saddle 8 is an integral box-shaped structure formed by bending, with fewer parts and fewer welding points. The end frame 2 strengthens the support of the tank 1 through the saddle 8, thereby improving the overall strength.
[0021] like Figures 1-8As shown, a reinforcing diagonal brace 206 is provided between adjacent end beams 202 and corner posts 204. A corner reinforcement 207 is provided at the corner formed by the corner post 204 and the end beam 202. The corner reinforcement 207 is fixedly connected to the corner post 204 and the end beam 202 respectively. The reinforcing diagonal brace 206 and the corner reinforcement 207 work together to improve the overall strength of the end frame 2. Specifically, the corner reinforcement 207 is a triangular plate or a trapezoidal plate.
[0022] like Figures 1-8 As shown, a reinforcing diagonal brace 9 connects the lower corner piece 205 to the saddle plate 7. The reinforcing diagonal brace 9 connects the saddle plate 7 and the end frame 2, resulting in better overall integrity, a more reasonable stress structure, and the ability to distribute stress and reduce deformation.
[0023] like Figures 1-8 As shown, further, the inner side of the reinforcing diagonal brace 9 is connected to a bottom reinforcing member 10. The bottom reinforcing member 10 is connected to the saddle plate 7 and the lower end beam 202 respectively. The bottom reinforcing member 10 connects the reinforcing diagonal brace 9, the saddle plate 7 and the lower end beam 202, making the stress structure more reasonable, dispersing the stress and reducing deformation. Specifically, the bottom reinforcing member 10 is a triangular plate or a trapezoidal plate.
[0024] like Figures 1-8 As shown, a lower reinforcing block 208 is provided at the corner formed by the lower corner piece 205 and the lower end beam 202. The bottom reinforcing member 10 is connected to one side of the lower reinforcing block 208, which strengthens the connection between the lower end beam 202 and the lower corner piece 205, provides reasonable stress distribution, is not easily deformed, and increases the connection area of the lower reinforcing block 208, making the connection of the bottom reinforcing member 10 more secure.
[0025] like Figures 1-8 As shown, an intermediate reinforcing member 209 is provided between two adjacent reinforcing diagonal bars 206. The two ends of the intermediate reinforcing member 209 are fixedly connected to the reinforcing diagonal bars 206 respectively, and the bottom side of the intermediate reinforcing member 209 is fixedly connected to the end beam 202. The force is reasonable. Specifically, the shape of the intermediate reinforcing member 209 is an isosceles trapezoidal plate.
[0026] like Figures 1-8As shown, the multi-zone air intake and unloading device 3 includes at least one unloading branch pipe 301 disposed on the cylinder 101, an air intake main pipe 302, at least one air intake assembly, and an unloading main pipe 303. The air intake assembly includes a tee joint disposed on the air intake main pipe 302 and two air intake connecting pipes connected to the tee joint. Each air intake connecting pipe is connected to two air intake branch pipes respectively. The air intake branch pipes are connected to the interior of the cylinder 101. The unloading branch pipe 301 is connected to the unloading main pipe 303. One end of the unloading main pipe 303 is provided with a total unloading outlet. The air intake main pipe 302 is provided with a blowing aid pipe 331, which is connected to the air intake main pipe 302 and the unloading main pipe 303 respectively.
[0027] like Figures 1-8 As shown, specifically, there are three intake components: a first intake component, a second intake component, and a third intake component. The first intake component includes a tee connector A304 disposed on the main intake pipe 302, a first intake connecting pipe 305 and a second intake connecting pipe 306 connected to the tee connector A304, a first intake branch pipe 307 and a second intake branch pipe 308 connected to the first intake connecting pipe 305, a third intake branch pipe 309 connected to the second intake connecting pipe 306, and a third intake branch pipe 309 connected to the second intake connecting pipe 306. The four intake branch pipes 310 are connected to the interior of the cylinder 101 via the first intake branch pipe 307, the second intake branch pipe 308, the third intake branch pipe 309, and the fourth intake branch pipe 310. Specifically, the first intake connecting pipe 305 is connected to the first intake branch pipe 307 and the second intake branch pipe 308 via a three-way connecting pipe a311, and the second intake connecting pipe 306 is connected to the third intake branch pipe 309 and the fourth intake branch pipe 310 via a three-way connecting pipe b312. Thus, the first intake assembly has four intake branch pipes.
[0028] like Figures 1-8 As shown, the second intake assembly includes a tee connector B313 disposed on the main intake pipe 302, a third intake connecting pipe 314 and a fourth intake connecting pipe 315 connected to the tee connector B313, a fifth intake branch pipe 316 and a sixth intake branch pipe 317 connected to the third intake connecting pipe 314, and a seventh intake branch pipe 318 and an eighth intake branch pipe 319 connected to the fourth intake connecting pipe 315. The fifth intake branch pipe 316... The sixth intake branch pipe 317, the seventh intake branch pipe 318, and the eighth intake branch pipe 319 are connected to the interior of the cylinder 101. Specifically, the third intake connecting pipe 314 is connected to the fifth intake branch pipe 316 and the sixth intake branch pipe 317 through a three-way connecting pipe c320, and the fourth intake connecting pipe 315 is connected to the seventh intake branch pipe 318 and the eighth intake branch pipe 319 through a three-way connecting pipe d321. Thus, the second intake assembly has four intake branch pipes.
[0029] like Figures 1-8 As shown, the third intake assembly includes a tee connector C322 disposed on the main intake pipe 302, a fifth intake connecting pipe 323 and a sixth intake connecting pipe 324 connected to the tee connector C322, a ninth intake branch pipe 325 and a tenth intake branch pipe 326 connected to the fifth intake connecting pipe 323, and an eleventh intake branch pipe 327 and a twelfth intake branch pipe 328 connected to the sixth intake connecting pipe 324. The ninth intake branch pipe 325, the tenth intake branch pipe 326, the ninth intake branch pipe 327, and the tenth intake branch pipe 328 are also connected to the main intake pipe 302. Pipe 326 is connected to the interior of the cylinder 101. Specifically, the fifth air inlet connecting pipe 323 is connected to the ninth air inlet branch pipe 325 and the tenth air inlet branch pipe 326 through a three-way connecting pipe e329, and the sixth air inlet connecting pipe 324 is connected to the eleventh air inlet branch pipe 327 and the twelfth air inlet branch pipe 328 through a three-way connecting pipe f330. In this way, the third air inlet assembly has 4 air inlet branch pipes, and the 3 air inlet assemblies have a total of 12 air inlet branch pipes, realizing multi-area air inlet, which can significantly accelerate the flow of powder in each area, thereby improving the unloading efficiency.
[0030] It is worth noting that the three air intake components are one embodiment, and the number of air intake components can be determined according to the length of the tank 1.
[0031] The tee connector has two outlets and one inlet. The tee connector is equipped with a tee control valve to control the opening and closing of the tee connector, which can control the intake of air through the intake connection pipe.
[0032] like Figures 1-8 As shown, the unloading main pipe 303 is provided with a main unloading outlet at one end. Specifically, there are two unloading branch pipes 301, both of which are connected to the unloading main pipe 303. The powder flows to the two unloading branch pipes 301, improving the unloading efficiency and preventing the powder from flowing to the same unloading branch pipe 301 and clogging it.
[0033] like Figures 1-8 As shown, the main air intake pipe 302 is provided with a blowing aid pipe 331, which is connected to the main air intake pipe 302 and the main unloading pipe 303 respectively. The blowing aid pipe 331 can avoid blockage and improve unloading efficiency.
[0034] like Figures 1-8As shown, the unloading main pipe 303 is equipped with a first pressure gauge 332 to monitor the pressure inside the unloading main pipe 303, and the air inlet main pipe 302 is equipped with a second pressure gauge 333 to monitor the pressure inside the air inlet main pipe 302. The ash collection trough 4 is equipped with a ventilated belt 334, and an air inlet pipe 335 is provided at each end of the ventilated belt 334. The air inlet pipe 335 is connected to the air inlet main pipe 302 and introduces gas into the ventilated belt 334 to unload the powder in the ash collection trough 4. Further details are omitted.
[0035] like Figures 1-8 As shown, the bottom of the ash collection trough 4 is fixedly connected with a plurality of first air intake support assemblies for fixing the three-way connecting pipe. The first air intake support assembly includes a first air intake fixing plate 11 and two first air intake support rings 12 symmetrically arranged on the first air intake fixing plate 11. The two opposite ends of the three-way connecting pipe pass through the corresponding first air intake support rings 12. The first air intake support rings 12 are U-shaped and the first air intake support rings 12 are detachably connected to the first air intake fixing plate 11.
[0036] like Figures 1-8 As shown, a plurality of second air intake support assemblies are fixedly connected to the bottom of the outer periphery of the cylinder 101. The second air intake support assembly includes a second air intake fixing plate 13 and a second air intake support ring 14 disposed on the second air intake fixing plate 13. The main air intake pipe 302 passes through the second air intake support ring 14, and the second air intake support ring 14 is detachably connected to the second air intake fixing plate 13.
[0037] like Figures 1-8 As shown, multiple unloading support assemblies are fixedly connected to the bottom of the outer periphery of the cylinder 101. The unloading support assembly includes an unloading fixing plate 15 and an unloading support ring 16 disposed on the unloading fixing plate 15. The unloading main pipe 303 passes through the unloading support ring 16, and the unloading support ring 16 and the unloading fixing plate 15 are detachably connected.
[0038] like Figures 1-8 As shown, the saddle plate 7 has a clearance groove 701 on its lower side and a clearance notch 702 on the upper side of one end of the saddle plate 7. The clearance groove 701 is used to avoid the intake branch pipe. Specifically, two arc-shaped reinforcing ribs 103 are provided on both sides of the dust accumulation groove 4. The clearance notch 702 facilitates the avoidance of the reinforcing ribs 103.
[0039] like Figures 1-8As shown, the powder tank container also includes a positive and negative pressure protection pipeline assembly. The positive and negative pressure protection pipeline assembly includes a negative pressure inlet pipe 17, a first safety control valve 18, a three-way connector 19, a filter ventilation device 20, an exhaust pipe 21, a second safety control valve 22, and a switch valve 23 connected in sequence. The switch valve 23 is connected to the unloading main pipe 303. The negative pressure inlet pipe 17 is located on the periphery of the tank body 1. The filter ventilation device 20 is connected to the inside of the tank body 1. When the pressure inside the tank body 1 is too high, the gas inside the tank body 1 enters the exhaust pipe 21 from the bottom of the filter ventilation device 20, and then goes to the unloading main pipe 303 for exhaust, thereby achieving positive pressure protection for the tank body 1. When the pressure inside the tank body 1 is too low, the gas inside the tank body 1 flows through the filter ventilation device 20 from the negative pressure inlet pipe 17, and then enters the tank body 1 for pressurization, thereby achieving negative pressure protection for the tank body 1.
[0040] Specifically, the three-way connector 19 has a first interface, a second interface, and a third interface. The first interface is connected to the negative pressure intake pipe 17, the second interface is connected to the exhaust pipe 21, and the third interface is connected to the filter ventilation device 20. The first safety control valve 18 and the second safety control valve 22 are commonly available valves that automatically open and close according to the pressure. The three-way connector 19 can be a three-way fitting or a self-made three-way connecting pipe.
[0041] like Figures 1-8 As shown, an exhaust support assembly for supporting the exhaust pipe 21 is provided on the outer periphery of the tank body 1. Further, the exhaust support assembly includes a connecting rod connected to the outer periphery of the tank body 1 and an exhaust support ring connected to the connecting rod. The exhaust pipe 21 passes through the exhaust support ring. The connecting rod is installed at the bottom of the outer periphery of the tank body 1. The exhaust support ring can support the exhaust pipe 21 and prevent the exhaust pipe 21 from falling off.
[0042] like Figures 1-8 As shown, a one-way valve 24 and a transition pipe 27 are sequentially connected between the discharge main pipe 303 and the switching valve 23. The connecting pipe is connected to the discharge main pipe 303. The switching valve 23 is connected to the discharge main pipe 303 through the one-way valve 24 and the transition pipe 27. The one-way valve 24 prevents the powder from flowing back into the exhaust pipe 21.
[0043] like Figures 1-8 As shown, the switching valve 23 is a ball valve, which is simple and quick to operate and easy to select. The first safety control valve 18 adopts an automatic switch check valve or a commonly available automatic switch safety valve. The second safety control valve 22 adopts a commonly available automatic switch safety valve. The positive and negative pressure protection pipeline of this application can automatically balance the pressure in the tank 1.
[0044] like Figures 1-8As shown, the negative pressure air inlet pipe 17 is a bent pipe. Optimal, the negative pressure air inlet pipe 17 is a 90° bend. The inlet of the negative pressure air inlet pipe 17 faces the tank body 1. This is beneficial for waterproofing and reduces dust accumulation. If the negative pressure air inlet pipe 17 is a straight pipe, although air can enter, rainwater can easily enter the negative pressure air inlet pipe 17 during rainy days, which can seriously cause the powder inside the tank body 1 to stick together.
[0045] like Figures 1-8 As shown, corresponding through holes (not shown) are provided on the connecting ring 5, which is beneficial for the routing of the exhaust pipe 21 and can also limit the exhaust pipe 21 to prevent it from shaking excessively.
[0046] like Figures 1-8 As shown, one of the end frames 2 is provided with a limiting component, which includes a limiting connecting plate 25 connected to the end frame 2 and a limiting ring 26 connected to the limiting connecting plate 25. The exhaust pipe 21 passes through the limiting ring 26, which can limit the shaking of the exhaust pipe 21.
[0047] like Figures 1-8 As shown, specifically, the limiting ring 26 has a U-shaped structure or an annular structure. When the limiting ring 26 has a U-shaped structure, it can be directly welded to the limiting connecting plate 25, or the two ends of the limiting ring 26 are provided with threads, and the limiting connecting plate 25 is provided with two threaded holes accordingly. The limiting ring 26 and the limiting connecting plate 25 are detachably connected, which is convenient for installation and disassembly. When the limiting ring 26 has an annular structure, it is welded to the limiting connecting plate 25.
[0048] The specific working process is as follows: the air intake manifold 302 is connected to the air source, and the blowing aid pipe 331 is opened to allow gas to enter the unloading manifold 303. Specifically, the air intake manifold 302 is detachably equipped with an air intake elbow joint, which is equipped with an air intake main valve to control the opening and closing of the air intake manifold 302. The blowing aid pipe 331 is equipped with a blowing aid control valve to control the gas to enter the unloading manifold 303 for blowing aid, thereby improving the unloading efficiency.
[0049] Open the valve on the air inlet branch pipe to allow gas to enter the tank 1, enabling multi-zone air intake of the fluidized bed 30 and initiating unloading. Specifically, there are 12 air inlet branch pipes. The fluidized bed 30 includes two symmetrically arranged fluidized bed plates 3001, each divided into 6 air inlet zones along its length, thus dividing the fluidized bed 30 into 12 air inlet zones. Each air inlet zone corresponds to one air inlet branch pipe, ensuring excellent flowability of the powder in each zone of the fluidized bed 30, resulting in a large effective unloading volume and significantly reducing powder residue to below 1%. The third air inlet branch pipe 309, the fourth air inlet branch pipe 310, the seventh air inlet branch pipe 318, and the eighth air inlet branch pipe 319 ensure excellent flowability of the powder near the end caps 102, solving the technical problem of easy powder residue at the end caps 102 of existing tank containers.
[0050] like Figures 1-8 As shown, fluidized bed 30 is provided with fluidizing guide end plates 31 at both ends. The fluidizing guide end plates 31 have arc surfaces and are connected to the inner wall of end cap 102. They can guide the powder in end cap 102 to flow and reduce the residue of material in end cap 102.
[0051] like Figures 1-8 As shown, the flow guide 6 is pyramid-shaped with four flow guide surfaces, allowing the powder to flow on all four sides of the flow guide 6, preventing powder accumulation. Specifically, the flow guide 6 is made of four triangular-shaped flat plates welded together or two bent plates welded together.
[0052] like Figures 1-8 As shown, the guide member 6 is provided with a pipe connector on the side facing the unloading branch pipe 301. The two ends of the pipe connector are respectively connected to the unloading pipe and the guide member 6. The unloading branch pipe 301 is generally directly inserted into the cylinder 101 and is mainly fixed by the cylinder 101. However, the material entering the unloading branch pipe 301 will generate an impact force, causing the unloading branch pipe 301 to shake, affecting the unloading, and may also cause the cylinder 101 to deform, shortening the service life of the cylinder 101. The pipe connector can fix the unloading branch pipe 301, prevent the unloading branch pipe 301 from shaking, and prevent the cylinder 101 from deforming.
[0053] like Figures 1-8As shown, the pipe connector includes a first pipe connecting plate 28 disposed on the side of the guide 6 facing the unloading branch pipe 301, and a second pipe connecting plate 29 disposed on the outer periphery of the unloading branch pipe 301. The first pipe connecting plate 28 is connected to the unloading branch pipe 301, and the second pipe connecting plate 29 is connected to the unloading branch pipe 301. The first pipe connecting plate 28 and the second pipe connecting plate 29 are detachably connected. The pipe connector can be configured as an integral structure, with both ends of the pipe connector directly welded to the guide 6 and the unloading branch pipe 301. However, this would make it difficult to disassemble the unloading branch pipe 301. Therefore, the pipe connector is configured such that the first pipe connecting plate 28 and the second pipe connecting plate 29 are detachably connected, which facilitates the disassembly and replacement of the unloading branch pipe 301 during subsequent maintenance and cleaning.
[0054] like Figures 1-8 As shown, the first pipe connecting plate 28 and the second pipe connecting plate 29 are L-shaped to facilitate the connection of the guide member 6 and the unloading branch pipe 301.
[0055] like Figures 1-8 As shown, the first pipe connecting plate 28 is provided with at least one adjustment hole (not shown), and a bolt is inserted into the adjustment hole. This allows for adjustment according to the position of the unloading branch pipe 301 during installation, improving installation flexibility. Furthermore, the adjustment hole is oblong in shape.
[0056] Any numerical values cited herein include all values ranging from a lower limit to an upper limit, increasing by one unit, with at least two units between any lower and any higher value. For example, if the quantity of a component or the value of a process variable (e.g., temperature, pressure, time, etc.) is described as being from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, the purpose is to illustrate that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification. For values less than 1, a unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1, etc. These are merely examples intended for explicit expression, and it can be assumed that all possible combinations of values listed between the minimum and maximum values are explicitly described in this specification in a similar manner.
[0057] Unless otherwise stated, all ranges include the endpoints and all numbers between them. The terms "approximately" or "about" used with ranges apply to both endpoints of the range. Thus, "approximately 20 to 30" is intended to cover "approximately 20 to approximately 30," including at least the specified endpoints.
[0058] All articles and references disclosed herein, including patent applications and publications, are incorporated herein by reference for various purposes. The term “substantially constitutes…” used to describe a combination should include the identified elements, components, parts, or steps, as well as other elements, components, parts, or steps that do not substantially affect the essential novelty of the combination. The use of the terms “comprising” or “including” to describe combinations of elements, components, parts, or steps herein also contemplates embodiments substantially constituted by such elements, components, parts, or steps. The use of the term “may” herein is intended to indicate that any described attribute included by “may” is optional.
[0059] Multiple elements, components, parts, or steps can be provided by a single integrated element, component, part, or step. Alternatively, a single integrated element, component, part, or step can be divided into multiple separate elements, components, parts, or steps. The use of "a" or "an" to describe an element, component, part, or step does not imply the exclusion of other elements, components, parts, or steps.
