Description

Technical Field

[0001] The invention relates to a buffer storage tank for chemical raw materials and belongs to the technical field of chemical storage tanks. Background Art

[0002] Chemical raw material storage tanks are large containers or facilities used to store various chemical raw materials. In the modern chemical industrial production system, chemical raw material storage tanks, as key infrastructure, are widely used in many fields such as petroleum refining, fine chemicals, pharmaceuticals, fertilizers, dyes, polymer materials, etc., and undertake important functions such as raw material reception, temporary storage of intermediate products, storage of finished products and logistics allocation.

[0003] During the transportation of traditional storage tanks, dynamic loads such as acceleration and deceleration, steering, and road bumps during vehicle operation can cause the liquid inside the tank to slosh violently. This sloshing generates significant hydraulic impact forces that directly act on the tank's inner walls, roof, and bottom structures.

[0004] Specifically, the impact of liquid in the storage tank will cause dynamic imbalance phenomena such as increased vibration of the tank body and shift of the center of gravity. In severe cases, it will cause the transport vehicle and the storage tank to overturn together. On the other hand, long-term and repeated liquid impact loads will produce alternating stress in the tank structure, which will not only accelerate the initiation and expansion of fatigue cracks in the material and shorten the service life of the equipment, but may also lead to major safety accidents such as leakage of chemical raw materials due to structural failure, posing a threat to the environment and personnel safety.

[0005] To mitigate the hazards of liquid sloshing and impact in storage tanks, the traditional approach is to install fixed partitions in the tank to divide the space into several fixed areas, thereby reducing the overall sloshing amplitude and impact force of the liquid. However, fixed partitions cannot adjust the size of the partition space according to the amount of stored liquid and the liquid level. When the stored liquid cannot fill the partition space, the liquid will still slosh significantly within the area defined by the fixed partition, impacting the partition and the tank body. In addition, fixed partitions are difficult to effectively dissipate the kinetic energy of liquid sloshing, and there is still a rigid impact between the liquid and the partition, causing the partition and the tank body to continue to bear the alternating stress generated by the sloshing, accelerating material fatigue. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: to overcome the shortcomings of the existing technology and provide a buffer storage tank for chemical raw materials, which is equipped with movable partitions and floating plates inside.

[0044] like Figures 1-18 As shown, this embodiment is implemented through the following technical solution: the tank body 1 and the tank cover module 3 are arranged in coordination.

[0045] An elastically tensionable telescopic module 2 is provided inside the tank body 1. The power input portion of the telescopic module 2 is cooperatively connected with the power output portion on the tank cover module 3. The tank cover module 3 can drive the telescopic module 2 to be retracted and extended step by step.

[0046] The telescopic module 2 is provided with retractable and stacked partition modules 4; the telescopic module 2 can drive the partition modules 4 to be unfolded or stacked step by step.

[0047] After the telescopic module 2 drives the partition module 4 to expand, the partition module 4 can divide the internal space of the tank body 1 into several chambers.

[0048] A floating plate assembly is provided on the tank cover module 3, and a portion of the floating plate assembly can float up and down along with the liquid level in the tank body 1, thereby limiting the fluctuation of the liquid level.

[0049] Specifically, the tank body 1 comprises a barrel body 101, wherein the bottom of the barrel body 101 is convex inwardly to form a support platform 102; and the bottom of the barrel body 101 is concave inwardly to form a seat groove 105 corresponding to the support platform 102. In this embodiment, a liquid discharge port is provided at the bottom of the barrel body 101.

[0050] The support platform 102 constrains the stored liquid to gather at a low position in the tank body 1, so that a small amount of stored liquid can be discharged from the tank body, avoiding tail liquid from remaining in the tank body 1. Figure 2 As shown; the support platform 102 is provided with a hollow first pedestal 103 and a second pedestal 104, the hollow structure of the first pedestal 103 and the second pedestal 104 facilitates the outflow of liquid from the inside thereof, and avoids the liquid remaining in the first pedestal 103 and the second pedestal 104 when the tank is discharged. Figure 2 、 Figure 3 shown.

[0051] Specifically, the telescopic module 2 includes: a telescopic cylinder assembly, a transmission screw 204 is provided on the telescopic cylinder assembly; a torque limiter 210 is also provided on the telescopic cylinder assembly, and the transmission screw 204 is connected to the telescopic cylinder assembly through the torque limiter 210; the transmission screw 204 is threadedly connected to the torque limiter 210, such as Figure 5 The drive screw 204 can drive the telescopic cylinder assembly through the torque limiter 210 to move.

[0052] In this embodiment, the power input portion of the telescopic module 2 is a transmission screw 204 .

[0053] The telescopic cylinder assembly includes: a fixed cylinder 201, an intermediate cylinder 202 and a top cylinder 203 nested from outside to inside; a tension spring 205 is provided on the fixed cylinder 201, the intermediate cylinder 202 and the top cylinder 203; the fixed cylinder 201, the intermediate cylinder 202 and the top cylinder 203 can be elastically linked by the tension spring 205, such as Figure 2 、 Figure 4 shown.

[0054] The torque limiter 210 is provided on the top cylinder 203 ; the fixed cylinder 201 is fixedly connected to the first pedestal 103 .

[0055] One end of the transmission screw 204 is rotatably connected to the second pedestal 104 via a bearing 207 ; a bearing cover 206 for limiting the position of the bearing 207 is provided on the second pedestal 104 .

[0056] A limiting ring 208 is provided at one end of the fixed cylinder 201 and the intermediate cylinder 202 ; and a drainage groove 209 is provided through the fixed cylinder 201 and the intermediate cylinder 202 .

[0057] The drain groove 209 facilitates the discharge of liquid from the telescopic cylinder assembly to prevent liquid from remaining inside the telescopic module 2. Figure 4 shown.

[0058] The outer walls of the fixed tube 201, the middle tube 202 and the top tube 203 are all provided with retaining rings 211 for limiting the partition module 4. In this embodiment, the retaining ring 211 is connected to the fixed tube 201, the middle tube 202 and the top tube 203 by a detachable threaded connection.

[0059] In this embodiment, the torque limiter 210 is a friction safety clutch, and preferably a steel ball safety clutch can also be used; conventionally, the torque limiter 210 is divided into a movable part and a fixed part. Within the torque limit range, the movable part can drive the fixed part to move synchronously. After exceeding the limited torque, the two parts are separated and the movable part continues to rotate relative to the fixed part; the transmission screw 204 and the movable part of the torque limiter 210 are threadedly matched. Within the torque limit range, the transmission screw 204 rotates, which can drive the torque limiter 210 as a whole to move axially along the transmission screw 204, and the torque limiter 210 moves synchronously with the top cylinder 203.

[0060] When the telescopic module 2 is extended, the transmission screw 204 drives the top cylinder 203 to move upward. Furthermore, the top cylinder 203 drives several intermediate cylinders 202 to rise and extend step by step through the tensioning spring 205. When the tensioning springs 205 of each stage are compressed to the limit position, the intermediate cylinder 202 and the top cylinder 203 reach the limit stroke, and the telescopic module 2 is fully unfolded. At this time, the torque limiter 210 is restricted by the top cylinder 203 and cannot continue to move along the transmission screw 204. Furthermore, if the transmission screw 204 continues to rotate, the torque applied to the torque limiter 210 increases. When the torque exceeds the limited torque, the movable part and the fixed part of the torque limiter 210 produce relative movement, and the transmission screw 204 cannot continue to drive the top cylinder 203 to rise, thereby protecting the telescopic cylinder assembly, the transmission screw 204 and the driving member 305, and preventing these components from being mechanically damaged due to overload.

[0061] Under the normal working state of the storage tank, the tensioning spring 205 in the telescopic cylinder assembly is not compressed to the limit state, and it still has room to move. The intermediate cylinder 202 and the tensioning spring 205 cooperate to move in the liquid stored in the tank body 1; when the liquid in the tank body 1 shakes, the liquid flow drives the partition 401 to move, and the partition 401 drives the intermediate cylinder 202 to move, and the tensioning spring 205 provides elastic support for the intermediate cylinder 202. The kinetic energy of the partition 401 is partially converted into the elastic potential energy of the tensioning spring 205, and the liquid flow is subjected to the damping effect of the partition 401 and the telescopic cylinder assembly; at the same time, the partition 401 produces a movement trend opposite to the liquid flow under the action of the tensioning spring 205, which hinders the movement of the liquid flow, and the kinetic energy of the liquid flow is consumed in the friction between it and the various components and the elastic potential energy of the tensioning spring 205.

[0062] Specifically, the tank cover module 3 includes: a cover body 301, and a floating plate assembly is arranged on the inner side of the cover body 301; The floating plate assembly includes a guide cylinder 302 mounted on the cover 301; a buoyancy spring 304 and an extension cylinder 303 are sheathed within the guide cylinder 302; the buoyancy spring 304 provides elastic support for the extension cylinder 303; a floating plate 309 is sheathed on the guide cylinder 302; one side of the floating plate 309 abuts against the extension cylinder 303; and the floating plate 309 is hinged to the cover 301 via a telescopic link assembly. The guide cylinder 302 and extension cylinder 303 provide guidance and support for the floating plate 309 during its floating motion.

[0063] The telescopic connecting rod assembly can elastically drive the floating plate 309 to fit onto the liquid surface in the tank body 1 .

[0064] Specifically, a flange ring 3021 for limiting the extension tube 303 is provided at the end of the guide tube 302 .

[0065] A flange 3031 is provided on the end surface of the extension tube 303 , and the floating plate 309 can abut against the flange 3031 ; in this embodiment, the flange 3031 is threadedly connected to the extension tube 303 .

[0066] The telescopic link assembly includes: a first extension rod 306 and a second extension rod 308 connected by a hinge; a spring rod 307 is hinged between the first extension rod 306 and the second extension rod 308; the first extension rod 306 is hinged to the inner side of the cover body 301, and one end of the second extension rod 308 is hinged to the floating plate 309.

[0067] The cover 301 is also provided with a driving member 305 and a mechanical seal 310 . The transmission screw 204 can pass through the floating plate assembly and be connected to the cover 301 through the mechanical seal 310 . The driving member 305 is connected to the transmission screw 204 and can drive the transmission screw 204 to rotate.

[0068] In this embodiment, the power output part on the tank cover module 3 is the driving member 305. Preferably, the driving member 305 is a motor, and the output shaft of the motor can be connected to the transmission screw 204 through a coupling; further, the driving member 305 can also use a crank as a backup, and the transmission screw 204 is manually rotated.

[0069] In this embodiment, a pressure balancing valve and a liquid level sensor, as well as an active control unit with a single chip microcomputer as the core, can also be provided on the cover body 301 of the tank cover module 3; in this embodiment, the liquid level sensor model is VEGAFLEX83, and a reserved hole for wiring the liquid level sensor is provided on the float plate 309. The detection head of the liquid level sensor can penetrate into the tank body 1 through the liquid flow channel 405; the driving member 305, the liquid level sensor and the control unit are electrically connected; when the driving member 305 adopts a motor, the control unit can drive the motor and the transmission screw 204 to rotate quantitatively according to the liquid level parameters fed back by the liquid level sensor, thereby adjusting the extension height of the telescopic module 2 and the working interval of the partition module 4 to adapt to the liquid level in the tank body 1. Figure 8 As shown, the cover body 301 is also provided with a liquid inlet.

[0070] The floating plate 309 includes: a central sleeve 3094, on the outer surface of which a grid plate 3091 and a flow stabilizer 3092 are provided at intervals, the grid plate 3091 being located above the flow stabilizer 3092, with a gap between the grid plate 3091 and the flow stabilizer 3092; a sealing lip ring 3093 is provided on the outer edge of the grid plate 3091, which can be attached to the inner wall of the barrel body 101; a flared portion 3095 is provided on the opening of the central sleeve 3094 near the guide cylinder 302; the flared portion 3095 is trumpet-shaped, and its diameter is larger than the outer diameter of the guide cylinder 302, so that the floating plate 309 can be connected and sleeved on the guide cylinder 302 when the floating plate 309 is retracted and floated. Figure 9 shown.

[0071] There are several holes on the grid plate 3091, such as Figure 9 As shown, the liquid level in the storage tank is evenly divided into the holes of the grid plate 3091. When the stored liquid in the tank body 1 shakes, the grid plate 3091 divides the liquid level into several holes, and the liquid level is restricted to fluctuate within the holes, thereby avoiding the overall fluctuation of the liquid level and generating large waves. At the same time, the stored liquid is subjected to the friction of the grid plate 3091, and the energy generated by the shaking of the stored liquid is consumed, further limiting the amplitude of the stored liquid fluctuation.

[0072] When the stored liquid is subjected to violent shaking, the flow stabilizer 3092 can block the liquid below the liquid level of the grid plate 3091 from surging up, preventing the liquid from passing through the grid plate 3091 to stir up liquid flow and foam, and assisting the grid plate 3091 to stabilize the separation of the liquid level; the sealing lip ring 3093 seals the gap between the grid plate 3091 and the inner wall of the barrel body 101 to prevent the liquid from surging up along the gap.

[0073] The telescopic connecting rod assembly elastically presses the floating plate 309 to fit the liquid surface, further limiting the stored liquid below the floating plate 309, preventing the floating plate 309 from being lifted up and losing its function when the liquid level fluctuates. At the same time, the spring rod 307 on the telescopic connecting rod assembly can consume part of the energy generated by the shaking of the stored liquid in the form of elastic potential energy, so that the shaking stored liquid can be quickly stabilized.

[0074] In this embodiment, the flow stabilizer 3092 and the grid plate 3091 are both made of hard foam, and the sealing lip ring 3093 is made of rubber. Preferably, the operator can select different materials for the grid plate 3091 and the flow stabilizer 3092 based on the density of the liquid to ensure that the floating plate 309 can float on the liquid surface. Specifically, the floating plate 309 can float on the liquid surface by relying on the buoyancy of the flow stabilizer 3092 and the grid plate 3091. The buoyancy of the floating plate 309 can overcome the elastic force of the spring rod 307.

[0075] Conventionally, the telescopic link assembly is in an extended state, at which time the spring rod 307 is extended and elastically supported between the first extension rod 306 and the second extension rod 308, and the telescopic rod assembly drives the floating plate 309 to press down, as shown in FIG. Figure 17 As shown; when the liquid level in the tank body 1 rises, the float 309 floats under the action of buoyancy, at this time the spring rod 307 is compressed, the first extension rod 306 and the second extension rod 308 fold and shrink, and the extension tube 303 shrinks into the guide tube 302, as shown Figure 2 shown.

[0076] In this embodiment, the direction of elastic support provided by the buoyancy spring 304 for the extension tube 303 is opposite to the direction of elastic support provided by the spring rod 307 for the floating plate 309; the elastic force of the buoyancy spring 304 is much smaller than the elastic force of the spring rod 307. The purpose of the buoyancy spring 304 is to support the extension tube 303 to contract as the floating plate 309 floats, while also preventing the extension tube 303 from extending outward and interfering with the rising of the telescopic module 2.

[0077] Specifically, the partition module 4 includes: a plurality of partitions 401 stacked and sleeved on the telescopic cylinder assembly, with foldable spoilers 403 hinged between the partitions 401; a plurality of damping valves 402 are embedded on the partitions 401, and the liquid flow can pass through the damping valves 402 and through the partitions 401.

[0078] In this embodiment, the spoilers 403 are arranged in pairs. When the partition module 4 is in the contracted state, the spoilers 403 are in the folded state. The folded spoilers 403 protrude toward the center of the partition 401. Figure 17 shown.

[0079] A fixing cap 404 is provided on the partition 401 , and the partition 401 can be connected to the telescopic cylinder assembly through the fixing cap 404 ; the side surface of the partition 401 can abut against the retaining ring 211 .

[0080] The fixed cylinder 201 , the middle cylinder 202 and the top cylinder 203 are all sleeved with partition plates 401 .

[0081] Specifically, the fixing cap 404 is fixedly connected to the fixing cylinder 201, the intermediate cylinder 202 and the top cylinder 203 by screws, and the partition 401 is pressed between the retaining ring 211 and the fixing cap 404 to achieve axial positioning; at the same time, a protrusion is provided on the fixing cap 404, which is inserted into the groove on the partition 401 to perform circumferential positioning on the partition 401, such as Figure 12 shown.

[0082] A liquid flow channel 405 is provided between the outer edge of the partition 401 and the inner wall of the barrel body 101. Figure 6 As shown, when the tank body 1 is being filled or discharged, the liquid can flow in the tank body 1 through the liquid flow channel 405 .

[0083] Specifically, the damping valve 402 includes: a through-shaped housing 4021, a bottom plate 4022 fixedly connected to the liquid outlet of the housing 4021, and a liquid outlet slot 4026 is provided on the bottom plate 4022; a valve plate 4023 is provided inside the housing 4021, and the valve plate 4023 abuts against the liquid inlet of the housing 4021; a pre-tightening nail 4024 is threadedly connected to the bottom plate 4022; Figure 11 shown.

[0084] A damping spring 4025 is provided in the mounting seat of the valve plate 4023, and the pre-tightening nail 4024 can be inserted into the mounting seat to abut against the damping spring 4025; the damping spring 4025 can support the valve plate 4023 to elastically abut against the liquid inlet of the housing 4021, thereby elastically sealing the liquid inlet of the housing 4021; Figure 11 shown.

[0085] When liquid passes through damping valve 402, liquid pressure acts on valve plate 4023, causing it to move and compress damping spring 4025. This releases the seal on the liquid inlet of housing 4021, allowing liquid to enter housing 4021 and exit through drain notch 4026. Tightening preload pin 4024 compresses damping spring 4025, increasing the elastic pressure on valve plate 4023. This increases the opening pressure required for valve plate 4023 and strengthens the damping force provided by damping valve 402. Conversely, loosening preload pin 4024 relaxes damping spring 4025, reducing the elastic pressure on valve plate 4023. This reduces the opening pressure required for valve plate 4023 and weakens the damping force provided by damping valve 402.

[0086] The valve plate 4023 is also provided with a plurality of liquid flow holes 4027, such as Figure 11 As shown; the residual liquid in the shell 4021 can be discharged through the liquid flow hole 4027, thereby avoiding liquid accumulation in the damping valve 402; in this embodiment, the aperture of the liquid flow hole 4027 is much smaller than the area of ​​the valve plate 4023, thereby limiting the flow rate of the liquid flow hole 4027 and ensuring that the impact force of the liquid mainly acts on the valve plate 4023.

[0087] When the stored liquid sways, it drives the partition 401 on the middle cylinder 202 to move. The damping valve 402 on the partition 401 is opened by the impact of the liquid flow. When the liquid flows through the damping valve 402, part of the energy of the liquid flow is consumed, thereby reducing the kinetic energy of the liquid flow and preventing the stored liquid from swaying. In this embodiment, multiple damping valves 402 are staggered according to the direction of opening to ensure that the damping valve 402 is activated when the partition 401 moves up and down. Figure 1 or Figure 10 shown.

[0088] The spoiler 403 includes: a frame 4031, a plurality of blades 4032 are evenly arranged in the frame 4031, and the intervals between the blades 4032 form a plurality of liquid flow gaps 4033; when the stored liquid shakes, the liquid flow can pass through the liquid flow gaps 4033, generating a damping effect, and at the same time, the plurality of blades 4032 increase the friction of the stored liquid flow. The combined effect of the two limits the flow of the stored liquid and prevents the stored liquid from shaking.

[0089] Specifically, the tank transfer base 5 includes: a base 505, on which a protective seat 501 for clamping the tank body 1 is movably connected; a plurality of lateral support modules are also provided on the base 505; when the protective seat 501 moves, it can drive the lateral support modules to support the base 505.

[0090] Specifically, a positioning platform 503 and several guard plates 502 are provided on the top of the protective seat 501; the positioning platform 503 can be snapped into the seat groove 105; the guard plates 502 are arranged around the periphery of the barrel body 101; and the bottom of the protective seat 501 is provided with several support columns 504. The positioning platform 503 not only provides positioning for the can body 1, but also forms a secure fixation for the can body 1 through its concave and convex fit with the seat groove 105, preventing the can body 1 from slipping on the protective seat 501. The guard plates 502 protect the can body 1 from impacts and knocks. In this embodiment, the guard plates 502 are made of plastic and can be further provided with anchor holes, to which straps can be fixed, so that the can body 1 can be reinforced and sealed manually with straps.

[0091] A plurality of support tubes 514 are provided on the base 505 , and the support columns 504 are slidably connected to the support tubes 514 . The support tubes 514 are also provided with return springs 515 that can provide elastic support for the support columns 504 .

[0092] The lateral support module includes: a guide rail 508 and a support seat 516 fixedly connected to the base 505, and a pressure plate 506 fixedly connected to the bottom of the protective seat 501; the support seat 516 is hinged with a main swing arm 511 and an auxiliary swing arm 512, and the main swing arm 511 and the auxiliary swing arm 512 are also hinged to the support beam 513 respectively; a movable hinge seat 509 is slidably connected to the guide rail 508; the movable hinge seat 509 is hinged to the pressure plate 506 through a push rod 507; the movable hinge seat 509 is hinged to the main swing arm 511 through a push rod 510.

[0093] In this embodiment, the main swing arm 511, the auxiliary swing arm 512, the support beam 513 and the support seat 516 form a parallelogram structure; the bottom surface of the support beam 513 is provided with an elastic anti-slip pad made of rubber.

[0094] The tank body 1 is placed on the protective seat 501 and pressed down. The protective seat 501 presses down and drives the lateral support module to the ground. The lateral support module expands the support range of the base 505, thereby providing strong support for the tank body 1 and preventing the tank body 1 from overturning due to centrifugal force during transportation. Figure 16 As shown, the protection seat 501 drives the pressure plate 506 to move downward, and the pressure plate 506 drives the movable hinge seat 509 to move outward through the push rod 507. Synchronously, the movable hinge seat 509 drives the push rod 510 to lift the proximal end of the main swing arm 511, and the distal end of the main swing arm 511 is pressed downward, and drives the auxiliary swing arm 512 and the support beam 513 to be pressed downward. Furthermore, the bottom of the support beam 513 is attached to the ground, and the lateral support module completes the extension support action.

[0095] Furthermore, after the tank body 1 is moved out, the protective seat 501 is reset under the action of the reset spring 515, the pressure plate 506 is lifted and drives the proximal end of the main swing arm 511 to be pressed down through the push rod 507, the movable hinge seat 509 and the push rod 510, and the distal end of the main swing arm 511 is lifted, and the auxiliary swing arm 512 and the support beam 513 are lifted accordingly. At this time, the lateral support module retracts toward the side of the base 505 to reduce space occupancy.

[0096] The specific operating principle of the present invention is as follows: During use, liquid chemical raw materials are filled into the tank body 1 from the liquid inlet of the cover body 301. After filling, the driving member 305 drives the transmission screw 204 to rotate quantitatively according to the amount of stored liquid, so that the telescopic module 2 and the partition module 4 are gradually raised and expanded. The stored liquid in the tank body 1 is divided into multi-layer chambers, and the partition 401 on the top layer of the partition module 4 is below the liquid level; the floating plate 309 is attached to the liquid surface in the tank body 1 under the action of the spring rod 307 to prevent the liquid level from fluctuating; during transportation, when the stored liquid is shaken, the liquid flow is damped by the damping valve 402 of the partition module 4 and the tensioning spring 205 on the telescopic module 2, and the kinetic energy of the liquid flow is greatly consumed. At the same time, the spoiler 403 further hinders the flow of liquid in the chamber. Under the combined action of the above structures, the shaking of the stored liquid is limited; when the tank is transported, the tank can also be installed on the tank transfer base 5 to ensure the transportation stability of the tank.

[0097] Of course, the above contents are only preferred embodiments of the present invention and should not be considered as limiting the scope of the embodiments of the present invention. The present invention is not limited to the above examples. Equivalent changes and improvements made by ordinary technicians in this technical field within the essential scope of the present invention should all fall within the scope of the patent of the present invention.
