Description

Technical Field

[0001] This invention relates to the field of storage tank technology, and more specifically, to a safe and stable storage tank for chemical applications. Background Technology

[0002] Currently, chemical companies mainly use storage tanks to store chemical products or semi-finished products. These storage tanks are generally made of metal. When the storage environment is at a high temperature or the weather is hot, heat is transferred to the storage tank, which may cause denaturation of the chemical products or semi-finished products stored inside. Therefore, it is necessary to cool the storage tanks. In the existing technology, air conditioning equipment and other refrigeration equipment are mainly used to cool the storage tanks. However, this method cannot quickly dissipate the heat inside the chemical products in the storage tank, resulting in poor cooling effect. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a safe and stable storage tank for chemical products. The technical problem to be solved by the present invention is that the existing storage tanks have poor cooling effect, which may lead to the denaturation of chemical products.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A safe and stable chemical storage tank, comprising a tank body, and further comprising:

[0006] The condenser pipes are installed at the upper and lower ends of the tank body. The condenser pipes, from top to bottom, include a first straight pipe connected end to end, a Z-shaped bend, and a second straight pipe.

[0007] A movable sleeve is fitted onto the condenser tube, the inner diameter of which is much larger than the outer diameter of the condenser tube;

[0008] An annular airbag is coaxially mounted inside the movable sleeve, and the annular airbag is sleeved on the condenser tube;

[0009] A driving device is provided on the tank body, which is used to drive the movable sleeve to move along the length of the condenser tube.

[0010] Furthermore, the upper and lower outer walls of the tank are respectively provided with a feed inlet and a discharge outlet.

[0011] Furthermore, the driving device includes:

[0012] A movable frame is vertically slidably connected to the tank body, and the middle part of the movable frame is hollowed out;

[0013] A sliding block is horizontally slidably connected to the movable frame. The movable frame has a sliding groove for the sliding block to engage. The sliding block slides freely horizontally within the sliding groove. A pivot is fixedly connected to the periphery of the movable sleeve. The sliding block has an insertion hole for the pivot to engage. The pivot rotates freely within the insertion hole.

[0014] A lifting assembly is provided on the top of the tank body, which is used to drive the movable frame to move up and down.

[0015] Furthermore, each of the two sides of the movable frame is fixedly connected to a protrusion, and a guide block is fixedly connected to the inner wall of the tank. The guide block has a guide groove for the protrusion to engage, and the protrusion slides freely up and down in the guide groove.

[0016] Furthermore, the lifting assembly includes:

[0017] A lead screw is vertically rotatably connected to the top of the tank body. The lead screw is driven to rotate by a servo motor installed on the top of the tank body. An ear plate is fixed to one side of the movable frame.

[0018] A nut is fitted into the ear plate, and the nut is threaded onto the lead screw.

[0019] Furthermore, the longitudinal section of the sliding block is rectangular.

[0020] Furthermore, the sliding block is provided with an inflation / deflation assembly for inflating and deflating the annular airbag.

[0021] Furthermore, the inflation / deflation assembly includes:

[0022] A hollow seat is fixed to the side wall of the sliding block. An air tube is installed on the lower outer wall of the hollow seat. The end of the air tube away from the hollow seat is connected to the annular airbag.

[0023] A piston is coaxially engaged within the hollow seat, and the piston slides freely up and down within the hollow seat;

[0024] A sliding rod is coaxially connected to the lower end face of the piston, and the lower end of the sliding rod extends out of the lower end face of the hollow seat and slides freely;

[0025] An elastic element installed inside the hollow seat is used to elastically push against the piston downwards.

[0026] A fixing plate is horizontally fixed to the side wall of the movable frame, and a fixing block is fixedly attached to the fixing plate.

[0027] Furthermore, a ball bearing is rotatably embedded at the lower end of the sliding rod, and the ball bearing rolls in contact with the upper surface of the fixing plate and the upper surface of the fixing block.

[0028] Furthermore, the elastic element is a spring vertically installed inside the hollow seat, with both ends of the spring elastically abutting against the inner top wall of the hollow seat and the piston, respectively.

[0029] The technical effects and advantages of this invention are as follows:

[0030] By installing a condenser tube, an external delivery system supplies coolant to the condenser tube. As the coolant flows inside the condenser tube, it exchanges heat with the chemical products inside the tank, thereby cooling the chemical products. Because it is in direct contact with the chemical products, the cooling effect is better. In addition, by installing a movable sleeve and an annular airbag, the movable sleeve is driven by a drive device to move along the length of the condenser tube, and the annular airbag can scrape off the chemical products adhering to the surface of the condenser tube. This avoids the chemical products in some parts of the tank from being in contact with the condenser tube for a long time, which would reduce the heat exchange efficiency between the condenser tube and the chemical products in other parts of the tank. Furthermore, the condenser tube is equipped with a Z-shaped bend, which improves the cooling efficiency of the chemical products.

[0031] By setting a sliding block and a pivot, the movable sleeve is rotatably connected to the sliding block via the pivot. In addition, the sliding block is horizontally slidably connected to the movable frame. Thus, when the movable frame moves vertically, the sliding block moves horizontally accordingly, and the movable sleeve rotates, thereby enabling the movable sleeve to move along the entire length of the condenser tube. During the movement, the annular airbag can scrape off the chemical products adhering to the surface of the condenser tube. The structure is simple and the operation is convenient.

[0032] By setting up an inflation / deflation assembly, when the annular airbag moves to the bend of the condenser tube, the gas inside the annular airbag decreases, allowing the annular airbag to relax and thus smoothly pass through the bend of the condenser tube, avoiding any obstruction to the movement of the annular airbag on the condenser tube.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1-8 As shown, this embodiment discloses a safe and stable chemical storage tank, including a tank body 2. The upper and lower outer walls of the tank body 2 are provided with an inlet 3 and an outlet 9. The inlet 3 is connected to a chemical raw material conveying system through a pipeline. In addition, control valves are installed on both the inlet 3 and the outlet 9. A condenser pipe 10 is installed on the tank body 2. The material of the condenser pipe 10 needs to ensure that it does not react chemically with the chemical raw materials. The condenser pipe 10 includes, from top to bottom, a first straight pipe, a Z-shaped bend, and a second straight pipe connected end to end. The first straight pipe is connected to the outlet of the coolant conveying system through a pipeline, and the second straight pipe is connected to the inlet of the coolant conveying system through a pipeline. In this way, the coolant conveying system conveys the low-temperature coolant to the first straight pipe, then to the second straight pipe through the Z-shaped bend, and then back to the coolant conveying system from the second straight pipe. During the circulation, the coolant can remove the heat of the chemical products in the tank body 2, thereby rapidly cooling the chemical products.

[0044] Guide blocks 11 are vertically welded to opposite sides of the inner wall of the tank body 2. Each guide block 11 has a notch-shaped guide groove. A movable frame 5 is installed inside the tank body 2. Protrusions 4 are welded to both ends of the movable frame 5 along its length. The two protrusions 4 engage with the two guide grooves and slide freely up and down within the guide grooves, allowing the movable frame 5 to slide vertically within the tank body 2. The middle of the movable frame 5 is hollow, and a movable sleeve 15 is installed within the hollow portion. The movable sleeve 15 is fitted onto the condenser tube 10, and the inner diameter of the movable sleeve 15 is much larger than the outer diameter of the condenser tube 10. An annular airbag 21 is coaxially installed inside the movable sleeve 15. The annular airbag 21 is inflatable and deflate; therefore, when the annular airbag... When the annular airbag 21 is inflated, its volume expands, causing the annular airbag 21 to fit tightly onto the condenser tube 10. In addition, when the annular airbag 21 slides on the condenser tube 10, it can scrape away the material on the surface of the condenser tube 10. The outer walls on both sides of the movable frame 5 in the width direction are provided with sliding grooves 13 in the form of through holes. The length direction of the sliding grooves 13 is parallel to the length direction of the movable frame 5. A sliding block 16 is fitted into the sliding groove 13. The sliding block 16 can slide freely in the sliding groove 13 along the length direction of the movable frame 5. In addition, a pivot 19 is welded on the periphery of the movable sleeve 15. The sliding block 16 is provided with a hole for the pivot 19 to be inserted. The pivot 19 can rotate freely in the hole, so that the movable sleeve 15 is rotatably connected to the sliding block 16.

[0045] A servo motor 1 is installed on the top of the tank body 2. A lead screw 8 is coaxially rotatably connected to the output shaft of the servo motor 1. The lower end of the lead screw 8 extends into the tank body 2. An ear plate 12 is welded to the side wall of the movable frame 5. A nut sleeve 4 is vertically inserted through the ear plate 12. The nut sleeve 4 is threaded onto the lead screw 8. When the output shaft of the servo motor 1 rotates, it will drive the lead screw 8 to rotate. The lead screw 8 and the nut sleeve 4 are threaded together, which will drive the nut sleeve 4 to move up and down, and drive the movable frame 5 to move up and down. When the movable frame 5 moves up and down, it will drive the movable sleeve 5 to move up and down. At the same time, the movable sleeve 5 will move along the length of the condenser tube 10. During the movement, the movable sleeve 5 will not generate much resistance when it moves on the condenser tube 10 due to the rotation of the pivot 19 and the horizontal movement of the sliding block 16 in the sliding groove 13. In addition, the longitudinal section of the sliding block 16 is rectangular, so the sliding block 16 will not rotate in the vertical plane in the sliding groove 13.

[0046] A hollow seat 20 is welded to the side wall of the sliding block 16 via a bracket. A connecting pipe is fixedly connected to the annular airbag 21, and the connecting pipe extends out of the movable sleeve 15. Additionally, an air pipe 17 is installed on the lower outer wall of the hollow seat 20, with one end of the air pipe 17 away from the hollow seat 20 connected to the connecting pipe. This allows the interior of the hollow seat 20 to communicate with the interior of the annular airbag 21. A piston 23, capable of sliding freely up and down, is engaged inside the hollow seat 20. When the piston 23 moves upward within the hollow seat 20, it draws air from the annular airbag 21 into the hollow seat 20, causing the annular airbag 21 to contract. Furthermore, when the annular airbag 21 moves... When the movement reaches the bend of the Z-shaped bend, the annular airbag 21 relaxes, allowing it to pass smoothly through the bend of the condenser tube 10. A sliding rod 18 is coaxially connected to the lower end face of the piston 23. The lower end of the sliding rod 18 extends out of the lower end face of the hollow seat 20 and slides freely. A spring 22 is vertically installed inside the hollow seat 20. The two ends of the spring 22 elastically abut against the inner top wall of the hollow seat 20 and the piston 23, respectively. A fixing plate 14 is fixedly connected to a fixing block 7. A ball bearing 24 is rotatably embedded at the lower end of the sliding rod 18. The ball bearing 24 rolls in contact with the upper surface of the fixing plate 14 and the upper surface of the fixing block 7.

[0047] When the sliding block 16 moves horizontally, it is pushed against the piston 23 by the elastic force of the spring 22, causing the ball 24 to contact the upper surface of the fixed plate 14. As the sliding block 16 approaches the fixed block 7, the ball 24 gradually rolls from the upper surface of the fixed plate 14 to the upper surface of the fixed block 17. This causes the ball 24 to drive the sliding rod 18 to move upward, and causes the piston 23 to overcome the elastic pushing force of the spring 22. When the piston 23 moves upward, it can draw some air from the annular airbag 21 into the hollow seat 20 through the air pipe 17. This allows the volume of the annular airbag 21 to shrink, thus allowing the annular airbag 21 to pass through the bend of the Z-shaped bend more smoothly and exit. After the bend, the ball bearing 24 rolls from the upper surface of the fixing block 7 to the upper surface of the fixing plate 14. Under the elastic resistance of the spring 22, the piston 23 moves downward, thereby squeezing the air in the hollow seat 20 into the annular airbag 21, causing the volume of the annular airbag 21 to expand again. This allows the annular airbag 21 to continue sliding on the first or second straight tube. Furthermore, in this embodiment, the number of fixing blocks 7 on each fixing plate 14 is set to two, and they correspond to the two bends of the Z-shaped bend, respectively, to ensure that the annular airbag 21 can be inflated or deflated when it moves to the two bends of the Z-shaped bend.

[0048] The working principle of this invention is as follows: The coolant delivery system delivers low-temperature coolant to the first straight pipe, then to the second straight pipe via the Z-shaped bend, and then back to the coolant delivery system from the second straight pipe. During the circulation, the coolant can remove the heat from the chemical products in the tank 2, thereby rapidly cooling the chemical products. During the cooling process, the servo motor 1 is started, and the output shaft of the servo motor 1 rotates, which drives the lead screw 8 to rotate. The lead screw 8 is screwed into the lead nut sleeve 4, which in turn drives the lead nut sleeve 4 to move up and down, and drives the movable frame 5 to move up and down. When the movable frame 5 moves up and down, it drives the movable sleeve 5 to move up and down. At the same time, the movable sleeve 5 will move along the length of the condenser pipe 10.

[0049] When the sliding block 16 moves horizontally, it is pushed against the piston 23 by the spring force of the spring 22, causing the ball 24 to contact the upper surface of the fixed plate 14. As the sliding block 16 approaches the fixed block 7, the ball 24 gradually rolls from the upper surface of the fixed plate 14 to the upper surface of the fixed block 17. This causes the ball 24 to drive the sliding rod 18 to move upward, and causes the piston 23 to overcome the elastic pushing force of the spring 22. When the piston 23 moves upward, it can draw some air from the annular airbag 21 into the hollow seat 20 through the air pipe 17, thus... The volume of the annular airbag 21 can be reduced, allowing it to pass smoothly through the bend of the Z-shaped tube. After passing through the bend, the ball bearing 24 rolls from the upper surface of the fixed block 7 to the upper surface of the fixed plate 14. Under the elastic resistance of the spring 22, the piston 23 moves downward, which in turn compresses the air in the hollow seat 20 into the annular airbag 21, causing the volume of the annular airbag 21 to expand again. This allows the annular airbag 21 to continue sliding on the first or second straight tube.
