Description

Technical Field

[0001] The invention belongs to the technical field of raw material storage tanks, and more specifically, particularly relates to a chemical raw material storage tank which is easy to clean. Background Art

[0002] Chemical raw material storage tanks play a vital role in the chemical industry. They are used to store various chemical raw materials, and play a role of buffering and transition between the procurement, transportation and production of raw materials, facilitating the allocation and management of raw materials. They can isolate and store dangerous, volatile, perishable or reactive chemical raw materials, reducing safety risks and the possibility of quality changes.

[0003] 1. Storage tanks usually adopt an integrated structural design. Pipe interfaces are installed at both ends of the storage tank. Through the pipe interfaces, operators can inject cleaning fluid or clean water into the storage tank to achieve the purpose of cleaning. However, due to the relatively small size of these pipe interfaces, the smaller pipe interfaces mean that the spray range of the cleaning fluid is limited, resulting in certain areas inside the storage tank may not be fully rinsed, thus affecting the overall effect and quality of cleaning.

[0004] 2. When cleaning the storage tank, you can first use a low-pressure water gun or steam to perform a preliminary flushing operation on the tank. After the initial flushing, you need to inject chemical solvents into the storage tank to dissolve the remaining chemical residues in the tank. Due to the limited size of the interface of the storage tank, the cleaning process cannot complete the cleaning of the entire tank at one time, so it needs to be done step by step. This step-by-step cleaning method will make the entire cleaning process time-consuming. Summary of the invention

The adjusting ring 39 moves downward between the fixed cylinder 37 and the top sleeve 43, and the adjusting ring 39 drives the second closing block 46 to insert into the bayonet at the top of the adjusting ring 39. At the same time, the adjusting ring 39 drives the first closing block 45 to continue to move downward, disconnecting the first closing block 45 from the docking interface inside the adjusting ring 39, so that the middle channel is opened.

The side end of each first connecting plate 18 is rotatably installed with two rotating rollers 28, and a hose 27 is arranged inside each rotating roller 28. The side end of the sealing plate 12 is fixedly installed with a feed pipe 21.

[0029] Working principle:

[0030] The first step is that when in use, multiple first connecting plates 18 push the second connecting plates 25, allowing the second connecting plates 25 to slide inside the guide frame 36, and the second connecting plates 25 fit against the inner wall of the tank body 11. Since the flexible plate 22 itself is a soft material, the support ring 17 itself has a certain elasticity. Under the pulling force of the multiple second connecting plates 25, the support ring 17 and the flexible plate 22 are both reset, and the support ring 17 and the flexible plate 22 expand to fit the inner wall of the tank body 11. The chemical raw materials are filled into the interior of the tank body 11 through the feeding pipe 21 on one side. At the same time, a discharge pipe 16 is installed at the side end of the sealing plate 12. After the chemical raw materials stored in the tank body 11 are discharged through the discharge pipe 16, the first pipe 14 is connected to the second pipe 15. The first pipe 14 is a double-layer design, and two different raw materials can be transported through the first pipe 14 at the same time. At the same time, the blower is connected through the second pipe 15, and the tank body is fed through the second pipe 15. 11, the first pipe 14 is a double-layer design, clean water and chemical solvents circulate in the first pipe 14 at the same time, and a plurality of rotating drums 28 are rotatably installed at the side end of the first connecting plate 18, and a plurality of hoses 27 are wound and installed inside each of the rotating drums 28. The first pipe 14 and the hoses 27 are interconnected to push the clean water and chemical solvents into the first connecting plate 18, and two third pipes 29 are installed inside the first connecting plate 18 to transport the solution and the air respectively. At the same time, the top of the first connecting plate 18 is interconnected with the U-shaped block 19, and the air is transported to the inside of the U-shaped block 19 through the third pipe 29 inside the first connecting plate 18. Two sets of mutually symmetrical nozzles 26 are installed at the top of the U-shaped block 19, and the top of the nozzle 26 is inclined. The airflow is impacted to the inside of the tank body 11 through the nozzle 26 to clean the water stains remaining on the inner wall of the tank body 11.

[0031] When in use, the motor inside the power box 24 controls the driving rod 31 to rotate at the side end of the power box 24, the driving rod 31 is sleeved inside the collar 32, the surface of the driving rod 31 is threaded, the driving rod 31 fits inside the third connecting plate 34, and the third connecting plate 34 moves toward the side end of the power box 24 through the rotation of the driving rod 31, and the third connecting plate 34 drives the positioning ring 35 to slide toward one side of the collar 32 first, and at the same time, the movement of the third connecting plate 34 causes the third connecting plate 34 to move to multiple The end of the first connecting plate 18 generates an oblique pulling force, and the other end of the first connecting plate 18 is connected to the second connecting plate 25. The second connecting plate 25 subjected to the pulling force slides inside the guide frame 36. The sliding of multiple second connecting plates 25 reduces the distance between the second connecting plates 25, allowing the second connecting plate 25 to drive the support ring 17 to move and bend. At the same time, the side end of the third connecting plate 34 is connected to the middle of the flexible plate 22, and the third connecting plate 34 moves toward the side end of the sleeve 32, driving the flexible plate 22 to bend and stretch synchronously. The flexible plate 22 is bent into a conical design under force, and at the same time, a pulling force is generated on the support ring 17, allowing the support ring 17 to bend. Through the bending of the support ring 17, the support ring 17 is disconnected from the inner wall of the tank body 11. The first pipe 14 is a double-layer design, and clean water and chemical solvents flow inside the first pipe 14 at the same time. One end of the first pipe 14 is connected to the fixed tube 37. At this time, the first closing block 45 is in the middle of the sealing sleeve 38, blocking the middle channel, and clean water enters the fixed tube through the outer channel. The inside of the fixed cylinder 37 is then sprayed toward the inner side of the tank body 11 through the splash port 44 at the top to flush the inner wall of the tank body 11. At the same time, the third connecting plate 34 drives the positioning ring 35 to the side end of the power box 24, so that the positioning ring 35 and the sleeve ring 32 are docked with each other. The driving rod 31 itself is rotating, and at the same time, the sleeve ring 32 is docked with the positioning ring 35, driving the power box 24 and the support ring 17 on one side to rotate as a whole, and cooperate with the splash port 44 to rotate and flush the inner wall of the tank body 11 to expand the flushing cleaning surface.

[0032] In the second step, the support ring 17 drives the second connecting plate 25 to slide inside the guide frame 36, leaving a gap between the support ring 17 and the tank body 11, and a driving motor is installed inside the control box 13. At the same time, the first pipe 14 and the second pipe 15 are connected to the inside of the control box 13, and the telescopic rod 23 is driven to extend and retract by the control box 13. One end of the telescopic rod 23 is connected to the sealing plate 12, and the top of the telescopic rod 23 generates a force on the power box 24, so that the power box 24 moves slowly to one side inside the tank body 11. While the U-shaped block 19 rotates and flushes the inside of the tank body 11, one end of the sealing plate 12 pulls the top of the hose 27 to allow The hose 27 pulls the rotating drum 28 to rotate at the side end of the first connecting plate 18. A torsion spring is installed inside the rotating drum 28. By pulling the hose 27, the rotating drum 28 rotates while adjusting the length of the hose 27 to complete the overall cleaning of the inside of the tank body 11. At the same time, by continuing to drive the driving rod 31, the driving rod 31 applies a pulling force to the third connecting plate 34, and then the third connecting plate 34 drives the positioning ring 35 to continue to squeeze the side end of the collar 32. The collar 32 is a telescopic design, and the end can be slid and compressed. By moving the third connecting plate 34, the third connecting plate 34 continues to drive the end of the deflection plate to deflect, thereby 5, the second connecting plate 25 continues to slide and compress inside the guide frame 36, and at the same time, two push rods 47 are rotatably installed on the side ends of the second connecting plate 25. The push rods 47 themselves are also a telescopic structure. In the process of the push rods 47 driving the positioning ring 35 to move the docking sleeve 32, the push rods 47 first compress their own volume. When the positioning ring 35 docks with the sleeve 32, the push rods 47 themselves are also compressed to the limit value, and continue to push the second connecting plate 25 to move, so that the second connecting plate 25 drives the push rods 47 to apply downward compression to the side ends of the adjusting ring 39, so that the adjusting ring 39 slides between the fixing tube 37 and the top sleeve 43. A top sleeve 43 and a sealing sleeve 38 are installed at the end. Both the fixed cylinder 37 and the sealing sleeve 38 are of multi-layer telescopic design. The adjusting ring 39 moves downward between the fixed cylinder 37 and the top sleeve 43. The adjusting ring 39 drives the second closing block 46 to insert into the bayonet at the top of the adjusting ring 39. At the same time, the adjusting ring 39 drives the first closing block 45 to continue to move downward, disconnecting the first closing block 45 from the docking interface inside the adjusting ring 39, opening the middle channel, and allowing the chemical solvent to clean the inner wall of the tank body 11 through the splash port 44. Two different solutions can be used to clean the inner wall of the tank body 11 through a top sleeve 43. The structure is compact and can be used alternately to reduce cleaning time.

[0033] The third step is to discharge the cleaned impurities through the discharge pipe 16 installed on one side of the sealing plate 12, and to ventilate the interior of the tank body 11, by driving the telescopic rod 23 to extend and retract, so that the telescopic rod 23 is extended and retracted toward the side end of the sealing plate 12, and at the same time, the power box 24 drives the driving rod 31 to rotate in the opposite direction, and the rotating driving rod 31 pushes the third connecting plate 34 to leave the side end of the power box 24, and the third connecting plate 34 drives the positioning ring 35 to leave. After the third connecting plate 34 is disconnected from the collar 32, the rotating force of the driving rod 31 acts tightly on the collar 32, and the driving rod 31 stops rotating the third connecting plate 34, and at the same time, the third connecting plate 34 moves toward the side end of the flexible plate 22, and the third connecting plate 34 drives the ends of the four deflection plates to deflect, and the deflection plates gradually rotate to a vertical state, and the top end of the first connecting plate 18 rotates at the end of the second connecting plate 25. The second connecting plate 25 is allowed to slide inside the nozzle 26, and the second connecting plate 25 slides out of the guide frame 36. The second connecting plate 25 drives the support ring 17 to reset. At the same time, the side end of the third connecting plate 34 drives the first connecting plate 18 to squeeze the flexible plate 22, so that the support ring 17 and the flexible plate 22 are gradually intact and reset, and fit with the inner wall of the tank body 11. At the same time, the second connecting plate 25 pulls the top of the two push rods 47 during the movement. The push rods 47 apply an upward force to the adjusting ring 39, so that the adjusting ring 39 moves upward at the top of the fixing tube 37. The adjusting ring 39 drives the sealing sleeve 38 to stretch upward. At the same time, the adjusting ring 39 drives the guide frame 36 to leave the interior of the adjusting ring 39. However, under the reverse force of the adjusting ring 39, the positioning ring 35 is inserted upward into the interior of the adjusting ring 39, automatically reset, and switched to the first splashing mode.
