Description

TECHNICAL FIELD

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

[0002] The chemical raw material storage tank is a large container or facility for storing various chemical raw materials. In the modern chemical industry production system, the chemical raw material storage tank, as key infrastructure, is widely used in the fields of petroleum refining, fine chemical industry, pharmaceutical industry, chemical fertilizer industry, dye industry, polymer material industry and the like, and bears important functions such as raw material receiving, intermediate product temporary storage, finished product storage and logistics allocation.

[0003] In the transportation link of the traditional storage tank, the dynamic load such as acceleration, deceleration, steering operation and road bumping generated when the vehicle runs can cause violent shaking of the liquid in the tank body. The shaking can generate significant liquid dynamic impact force, which directly acts on the inner wall, top and bottom structure of the storage tank.

[0004] Specifically, the liquid impact in the storage tank can cause dynamic imbalance phenomena such as tank body vibration aggravation and gravity center deviation, and in severe cases, can also cause the transportation vehicle and the storage tank to overturn together. On the other hand, the long-term repeated liquid impact load can generate alternating stress in the tank body structure, which not only accelerates the initiation and expansion of material fatigue cracks, shortens the service life of the equipment, but also can cause major safety accidents such as chemical raw material leakage due to structural failure, and poses a threat to the environment and personnel safety.

[0005] In order to reduce the harm of liquid shaking impact in the storage tank, the traditional method is to install fixed partitions in the tank to divide the space into several fixed areas, thereby reducing the overall shaking amplitude and impact force of the liquid. However, the fixed partitions cannot adjust the size of the divided space according to the liquid storage amount and liquid level. When the liquid storage cannot occupy the divided space, the liquid will still shake greatly in the fixed partition limited area, impacting the partition and the tank body. In addition, the fixed partitions are difficult to effectively reduce the kinetic energy of the liquid shaking, and the liquid and the partition are still in rigid impact, so that the partition and the tank body continue to bear the alternating stress generated by the shaking, accelerating the material fatigue. SUMMARY

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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 5As shown in the figure; the transmission screw 204 can drive the telescopic cylinder assembly through the torque limiter 210.

[0083] In this embodiment, the power input part of the telescopic module 2 is the transmission screw 204.

[0084] The telescopic cylinder assembly includes: a fixed cylinder 201, an intermediate cylinder 202 and a top cylinder 203 which are nested from outside to inside; the fixed cylinder 201, the intermediate cylinder 202 and the top cylinder 203 are provided with tension springs 205; the fixed cylinder 201, the intermediate cylinder 202 and the top cylinder 203 can be elastically linked through the tension springs 205, as Figure 2 , Figure 4 shown.

[0085] The torque limiter 210 is arranged on the top cylinder 203; the fixed cylinder 201 is fixedly connected to the first pedestal 103.

[0086] One end of the transmission screw 204 is rotatably connected to the second pedestal 104 through a bearing 207; the second pedestal 104 is provided with a bearing gland 206 for limiting the bearing 207.

[0087] One end of the fixed cylinder 201 and the intermediate cylinder 202 is provided with a limiting ring 208; the fixed cylinder 201 and the intermediate cylinder 202 are provided with a flow slot 209.

[0088] The flow slot 209 facilitates the discharge of liquid from the telescopic cylinder assembly, preventing liquid from remaining inside the telescopic module 2, as Figure 4 shown.

[0089] The outer wall of the fixed cylinder 201, the intermediate cylinder 202 and the top cylinder 203 is provided with a retaining ring 211 for limiting the partition plate module 4; in this embodiment, the connection between the retaining ring 211 and the fixed cylinder 201, the intermediate cylinder 202 and the top cylinder 203 is detachable screw connection.

[0090] In this embodiment, the type of torque limiter 210 is a friction safety clutch, and a steel ball safety clutch is also preferred; conventionally, the torque limiter 210 is divided into a movable part and a fixed part, the movable part can drive the fixed part to move synchronously within the torque limiting range, and when the limiting torque is exceeded, the two parts move separately, and the movable part continues to rotate relative to the fixed part; the transmission screw 204 is threadedly connected with the movable part of the torque limiter 210, within the torque limiting range, the transmission screw 204 can drive the torque limiter 210 to move axially along the transmission screw 204, and the torque limiter 210 moves synchronously with the top cylinder 203.

[0091] When the telescopic module 2 is extended, the transmission screw 204 drives the top cylinder 203 to move upwards, and further, the top cylinder 203 drives the intermediate cylinders 202 to move upwards and extend through the tension springs 205 step by step; when the tension springs 205 are compressed to the limit position, the intermediate cylinders 202 and the top cylinder 203 reach the limit stroke, at which time the telescopic module 2 is fully unfolded; at this time, the torque limiter 210 is limited by the top cylinder 203 and cannot continue to move along the transmission screw 204, and further, if the transmission screw 204 continues to rotate, the torque on the torque limiter 210 increases, and when the torque exceeds the limit torque, the movable part of the torque limiter 210 moves relative to the fixed part, and the transmission screw 204 cannot continue to drive the top cylinder 203 to move upwards, thereby protecting the telescopic cylinder assembly, the transmission screw 204 and the driving part 305 from mechanical damage due to overload.

[0092] In the conventional working state of the storage tank, the tension springs 205 in the telescopic cylinder assembly are not compressed to the limit state, and still have a space for movement, and the intermediate cylinders 202 and the tension springs 205 cooperate to move in the liquid in the tank body 1; when the liquid in the tank body 1 shakes, the liquid flow drives the baffle 401 to move, the baffle 401 drives the intermediate cylinders 202 to move, and the tension springs 205 provide elastic support for the intermediate cylinders 202, and the kinetic energy of the baffle 401 is partially converted into the elastic potential energy of the tension springs 205, and the liquid flow is subjected to the damping action of the baffle 401 and the telescopic cylinder assembly; at the same time, the baffle 401 generates a movement trend opposite to the liquid flow under the action of the tension springs 205, hinders the movement of the liquid flow, and the kinetic energy of the liquid flow is consumed in the friction with the components and the elastic potential energy of the tension springs 205.

[0093] Specifically, the tank cover module 3 comprises: a cover body 301, and a floating plate assembly arranged on the inner side of the cover body 301.

[0094] The floating plate assembly comprises: a guide cylinder 302 arranged on the cover body 301; the guide cylinder 302 is sleeved with a buoyancy spring 304 and an elongated cylinder 303 inside; the buoyancy spring 304 can provide elastic support for the elongated cylinder 303; the guide cylinder 302 is sleeved with a floating plate 309; one side of the floating plate 309 can abut against the elongated cylinder 303; the floating plate 309 is further hinged to the cover body 301 through a telescopic connecting rod assembly. The guide cylinder 302 and the elongated cylinder 303 can provide guidance and support for the floating plate 309 during the floating process of the floating plate 309.

[0095] The telescopic connecting rod assembly can elastically drive the floating plate 309 to abut against the liquid surface in the tank body 1.

[0096] Specifically, the end of the guide cylinder 302 is provided with a flange ring 3021 for limiting the elongated cylinder 303.

[0097] The end surface of the elongated cylinder 303 is provided with a flange 3031, and the floating plate 309 can abut against the flange 3031. In the embodiment, the flange 3031 is threadedly connected to the elongated cylinder 303.

[0098] The telescopic connecting rod assembly comprises a first elongated rod 306 and a second elongated rod 308 which are hingedly connected, and a spring rod 307 which is hingedly connected between the first elongated rod 306 and the second elongated rod 308. The first elongated rod 306 is hingedly connected to the inner side of the cover body 301, and one end of the second elongated rod 308 is hingedly connected to the floating plate 309.

[0099] The cover body 301 is further provided with a driving member 305 and a mechanical seal 310. The transmission screw rod 204 can pass through the floating plate assembly and is connected to the cover body 301 through the mechanical seal 310. The driving member 305 is connected to the transmission screw rod 204 and can drive the transmission screw rod 204 to rotate.

[0100] In the embodiment, the power output part of the tank cover module 3 is the driving member 305. Preferably, the driving member 305 is an electric motor, and the output shaft of the electric motor can be connected to the transmission screw rod 204 through a shaft coupling. Further, the driving member 305 can also use a crank as a backup, and manually drive the transmission screw rod 204 to rotate.

[0101] In the embodiment, the cover body 301 of the tank cover module 3 can be further provided with a pressure balance valve, a liquid level sensor, and an active control unit with a single-chip microcomputer as the core. In the embodiment, the model of the liquid level sensor is VEGAFLEX83. The floating plate 309 is provided with a reserved hole for wiring of the liquid level sensor, and the detection head part of the liquid level sensor can pass through the liquid flow channel 405 and enter the tank body 1. The driving member 305, the liquid level sensor, and the control unit are electrically connected. When the driving member 305 is an electric motor, the control unit can drive the electric motor and the transmission screw rod 204 to quantitatively rotate according to the liquid level parameter fed back by the liquid level sensor, so as to adjust the height of the telescopic module 2 and the working interval of the baffle module 4 to adapt to the liquid level in the tank body 1. As shown in Figure 8 The cover body 301 is further provided with a liquid inlet.

[0102] The floating plate 309 comprises a center sleeve 3094, and a grid plate 3091 and a flow stabilizing plate 3092 are arranged on the outer side of the center sleeve 3094 at intervals. The grid plate 3091 is located above the flow stabilizing plate 3092, and a gap is left between the grid plate 3091 and the flow stabilizing plate 3092. The outer edge of the grid plate 3091 is provided with a sealing lip ring 3093 which can be attached to the inner wall of the barrel body 101. The center sleeve 3094 is provided with an expanded portion 3095 near the opening of the guide cylinder 302. The expanded portion 3095 is trumpet-shaped, and its diameter is greater than the outer diameter of the guide cylinder 302, so as to facilitate the floating plate 309 to abut against and be sleeved on the guide cylinder 302 when it is floated upward, as shown in Figure 9 .

[0103] The grid plate 3091 is provided with a plurality of holes, as shown in the figure Figure 9 The liquid surface in the tank is evenly divided into the holes of the grid plate 3091, and when the liquid in the tank 1 is shaken, the liquid surface is limited to fluctuate in the holes due to the grid plate 3091, avoiding the overall fluctuation of the liquid surface to generate large waves, and at the same time, the liquid is subjected to the friction of the grid plate 3091, and the energy generated by the shaking of the liquid is consumed, further limiting the fluctuation amplitude of the liquid.

[0104] When the liquid is shaken violently, the flow stabilizing plate 3092 can block the liquid below the liquid surface of the grid plate 3091 from surging up, preventing the liquid from passing through the grid plate 3091 to generate liquid flow and foam, and assisting the grid plate 3091 to stabilize the divided liquid surface; the sealing lip ring 3093 closes the gap between the grid plate 3091 and the inner wall of the barrel body 101, preventing the liquid from surging up along the gap.

[0105] The telescopic connecting rod assembly elastically presses the floating plate 309 to fit onto the liquid surface, further limiting the liquid below the floating plate 309, preventing the floating plate 309 from being lifted up and losing its function when the liquid surface fluctuates, and 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 liquid in the form of elastic potential energy, so that the shaken liquid can be quickly stabilized.

[0106] In this embodiment, the flow stabilizing plate 3092 and the grid plate 3091 are both made of hard foam, and the sealing lip ring 3093 is made of rubber, and preferably, the operator can select the grid plate 3091 and the flow stabilizing plate 3092 made of different materials according to the density of the filled liquid to ensure that the floating plate 309 can float onto the liquid surface. Specifically, the floating plate 309 can float on the liquid surface by relying on the buoyancy of the flow stabilizing plate 3092 and the grid plate 3091, and the buoyancy of the floating plate 309 can overcome the elastic force of the spring rod 307.

[0107] Conventionally, the telescopic connecting rod assembly is in an extended state, at which time the spring rod 307 is extended and elastically supported between the first elongated rod 306 and the second elongated rod 308, and the telescopic rod assembly drives the floating plate 309 to be pressed down, as shown in the figure Figure 17 When the liquid surface in the tank 1 rises, the floating plate 309 is lifted up under the action of the buoyancy, at which time the spring rod 307 is compressed, the first elongated rod 306 and the second elongated rod 308 are folded and contracted, and the elongated cylinder 303 is contracted into the guide cylinder 302, as shown in the figure Figure 2 .

[0108] In the embodiment, the elastic support direction provided by the buoyancy spring 304 for the elongated cylinder 303 is opposite to the elastic support direction provided by the spring rod 307 for the floating plate 309; the elastic force of the buoyancy spring 304 is far less than the elastic force of the spring rod 307, and the purpose of the buoyancy spring 304 is to support the elongated cylinder 303 to shrink along with the floating of the floating plate 309, and also to avoid the elongated cylinder 303 from extending outwards to interfere with the lifting of the telescopic module 2.

[0109] Specifically, the baffle module 4 comprises: a plurality of baffles 401 which are sleeved on the telescopic cylinder assembly, and a plurality of foldable spoilers 403 which are hinged between the baffles 401; a plurality of damping valves 402 are embedded on the baffles 401, and liquid flow can pass through the baffles 401 through the damping valves 402.

[0110] In the embodiment, the spoilers 403 are arranged in pairs, and when the baffle module 4 is in the contracted state, the spoilers 403 are in the folded state, and the folded spoilers 403 protrude towards the center of the baffle 401, as shown in Figure 17 .

[0111] The baffle 401 is provided with a fixing cap 404, and the baffle 401 can be connected to the telescopic cylinder assembly through the fixing cap 404; the side surface of the baffle 401 can abut against the check ring 211.

[0117] When the liquid passes through the damping valve 402, the liquid pressure acts on the valve plate 4023, the valve plate 4023 moves and compresses the damping spring 4025, and further, the valve plate 4023 releases the closure of the liquid inlet of the shell 4021, the liquid enters the shell 4021 from the liquid inlet and flows out from the liquid outlet slot 4026. By tightening the pre-tightening pin 4024, the damping spring 4025 can be compressed, and the elastic pressure of the valve plate 4023 is increased, at this time, the opening pressure required by the valve plate 4023 is increased, and the damping force provided by the damping valve 402 is increased; on the contrary, by loosening the pre-tightening pin 4024, the damping spring 4025 can be relaxed, and the elastic pressure of the valve plate 4023 is reduced, at this time, the opening pressure required by the valve plate 4023 is reduced, and the damping force provided by the damping valve 402 is reduced.

[0119] When the liquid storage shakes, the baffle 401 on the middle cylinder 202 is driven to move, the damping valve 402 on the baffle 401 is opened under the impact of the liquid flow, and part of the energy of the liquid flow is consumed when passing through the damping valve 402, so as to reduce the kinetic energy of the liquid flow and prevent the liquid storage from shaking. In the embodiment, a plurality of damping valves 402 are staggered according to the opening direction, so as to ensure that the damping valves 402 move when the baffle 401 moves up and down, as shown in Figure 1 or Figure 10 .

[0120] The spoiler 403 includes a frame 4031, a plurality of blades 4032 are uniformly arranged in the frame 4031, and a plurality of liquid flow gaps 4033 are formed between the blades 4032; when the liquid storage shakes, the liquid flow can pass through the liquid flow gaps 4033, and the damping effect is generated, and at the same time, the plurality of blades 4032 increase the friction of the liquid flow, and the comprehensive effect of the two limits the liquid flow and prevents the liquid storage from shaking.
