Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion treatment, and particularly to an anti-corrosion treatment device for the surface of a plastic storage tank chassis. Background Art

[0002] A plastic storage tank is a corrosion-resistant storage container mainly made of polyethylene, and is mainly used in fields such as chemical industry, environmental protection, and food processing. When the plastic storage tank is filled with liquid, the pressure borne by the bottom is relatively large. In order to evenly disperse the weight at the bottom of the storage tank to a larger contact surface, a chassis for support is usually added at the bottom of the plastic storage tank to prevent the bottom of the tank body from expanding or cracking due to concentrated stress.

[0003] Since most of the structures used to support plastic storage tanks on the market are made of metal materials, and the metal chassis is easily rusted and corroded due to moisture when exposed to the external environment, which in turn affects the structural stability of the overall chassis. Therefore, after the chassis is completed and erected with the plastic storage tank, anti-corrosion treatment is usually required on the surface of the chassis. The traditional anti-corrosion treatment methods include sandblasting or chemical rust removal on the surface of the chassis, or the use of organic coatings, as well as methods such as metal plating and modification and electrochemical protection.

[0004] At present, the use of electrochemical protection can effectively ensure the anti-corrosion ability of the chassis. The electrochemical protection method usually connects active metals (such as magnesium, zinc) etc. as sacrificial electrodes to protect the main metal. When the existing sacrificial anodes are connected to the main metal, they usually need to be attached and fixed on the surface of the main metal, and the sacrificial anode metal itself will be consumed, and the consumption rate is determined according to the actual environmental conditions where the chassis is located. This easily leads to the sacrificial anode metal not being detected in time after being completely consumed, thereby affecting the anti-corrosion treatment effect of the chassis; secondly, when the plastic storage tank is connected to the chassis device, although the plastic storage tank has better corrosion resistance, there is still an easy situation where the bottom of the storage tank cracks due to excessive pressure. After the bottom of the plastic storage tank cracks, the internal solution will directly drip onto the ground and cannot be recycled. If the stored liquid is corrosive, it is easy to cause corrosion of the chassis; in addition, the existing chassis structure is usually a bottom column plus a ring frame structure, and the inner diameter of the ring frame is adapted to the outer diameter of the bottom of the storage tank. Since the chassis does not effectively extend outwards or is provided with a stability structure, and at the same time the chassis lifts the plastic storage tank to a relatively high position above the ground, the plastic storage tank placed on the chassis is prone to tipping, which is not conducive to ensuring the stability of the plastic storage tank.

[0007] Preferably, vertical strips are arranged on the outer wall of the top cover, clamping strips are arranged on the inner wall of the collar, and the collar is sleeved and connected to the top cover through the vertical strips and the clamping strips.

[0008] Preferably, the side plates are movably inserted into the clamping frames through the plastic storage tank, and the side plates are slidably connected to the vertical cylinder through the clamping frames.

[0009] Preferably, connecting rods are fixedly connected to the bottom and middle of the vertical column, a plurality of inclined support frames are arranged in the middle of the central column, and the top ends of the plurality of inclined support frames are respectively fixedly connected to the outer walls of the vertical column and the top of the vertical pipe.

[0010] Preferably, through holes are formed at the bottom end of the vertical pipe, and the zinc anode is connected to the ground through the through holes.

[0011] Preferably, the top end of the telescopic spring is fixedly connected to the bottom end of the support plate, the bottom end of the telescopic spring is fixedly connected to the bottom of the cavity, and an anti-corrosion coating is arranged on the inner wall of the cavity.

[0012] Preferably, a cross frame is fixedly connected to the bottom end of the base plate, and a plurality of magnesium anodes are arranged on the outer wall of the cross frame.

[0013] Preferably, the inside of the drain pipe is communicated with the inside of the cavity.

[0014] Preferably, the contact alarm is electrically connected to the built-in power supply, and the built-in power supply is a detachable structure.

[0015] Preferably, the transparent tube communicates with the inside of the vertical tube, and the transparent tube is fixedly connected to the base plate through the vertical tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this surface anti-corrosion treatment device for the bottom frame of a plastic storage tank, through the vertical tube, transparent tube, vertical rod, round block and contact alarm provided, the strip-shaped sacrificial anode metal can be vertically placed in the vertical cylinder and vertical tube. As the sacrificial anode is consumed through the through hole in contact with the ground, the length of the sacrificial anode in the vertical cylinder will become shorter, causing the vertical rod propped on the top of the sacrificial anode metal to slide down due to gravity. When the sacrificial anode metal is almost completely consumed, the contact sensor provided at the top of the vertical rod will contact the top surface of the screw cap, triggering the contact alarm to emit a beeping sound for alarm reminder. This is beneficial for promptly detecting the sacrificial anode metal that is about to be consumed completely, thereby reducing the adverse impact on the anti-corrosion effect of the bottom frame.

[0017] 2. In this surface anti-corrosion treatment device for the bottom frame of a plastic storage tank, through the vertical cylinder, support plate, telescopic spring, collar, side plate and clamping frame, when there is a leakage at the bottom of the plastic storage tank, the liquid in the storage tank will flow into the vertical cylinder from the leakage port. At the same time, the weight of the storage tank itself will become lighter, reducing the force on the telescopic spring that was originally under greater pressure. As a result, the telescopic spring can lift the storage tank and drive the collar to slide upward along the inner side of the clamping frame. At this time, the inspection personnel can judge whether there is a leakage in the plastic storage tank according to the position of the bottom end of the side plate and the clamping frame. At the same time, the leaked liquid in the storage tank will be concentrated in the vertical cylinder. After opening the solenoid valve, the liquid leaking from the storage tank can be discharged through the drain pipe and then collected and processed again, thus avoiding the corrosion of the bottom frame by the liquid leaking from the storage tank.

[0018] 3. In this surface anti-corrosion treatment device for the bottom frame of a plastic storage tank, through the central column, cross frame and base plate extending outward at the four corners, after the bottom of the device lifts the plastic storage tank, the pressure of the storage tank can be dispersed to the central column of the base plate and the vertical columns at the four corners, making the stress surface of the bottom frame larger. This reduces the situation where the plastic storage tank at the top topples due to the instability of the bottom frame, and is more beneficial for improving the stability of the plastic storage tank.

[0024] Such as Figures 1 to 6As shown, the surface anti-corrosion treatment device of the plastic storage tank chassis of this embodiment includes a base plate 7. The material of the base plate 7 is the same as that of the vertical column 8. At the same time, the four corners of the base plate 7 are passivated, so that the base plate 7 is not prone to safety hazards. The top of the base plate 7 is fixedly connected with a vertical cylinder 6. The top of the vertical cylinder 6 is provided with an opening. The plastic storage tank 1 is placed in the interior of the vertical cylinder 6 through the opening. At the same time, the outer diameter of the plastic storage tank 1 is adapted to the inner diameter of the vertical cylinder 6, so that the vertical cylinder 6 can cooperate with the plastic storage tank 1, which is beneficial to enhancing the stability of the connection between the plastic storage tank 1 and the chassis. When necessary, the sealing strip is sealed, and the vertical cylinder 6 itself is provided with a through hole. The through hole is conducive to the installation of the drainage pipe fittings of the plastic storage tank 1 and the gap is sealed. The top of the two side walls of the vertical cylinder 6 is A card frame 4 is provided, and a screw hole is also provided on one side wall of the card frame 4 so that the card frame 4 can pass through the fastening screws, which is used to lock and fix the side panels 5 inserted in the card frame 4 by fastening the screws during transportation, thereby facilitating the overall transportation of the chassis. At the same time, the card frame 4 functions to limit the side panels 5, so that when the side panels 5 are lifted up with the plastic storage tank 1, the stability of the plastic storage tank 1 can be ensured, and the probability of the plastic storage tank 1 tipping over can be reduced. A cavity 21 is provided inside the vertical cylinder 6. The cavity 21 functions to hold the plastic storage tank 1 filled with a solution, and can collect liquid seeping out of the plastic storage tank 1, so as to prevent the liquid seeping out of the plastic storage tank 1 from falling on the chassis, thereby reducing the adverse effect of the liquid on the anti-corrosion treatment effect on the surface of the chassis. The interior of the cavity 21 A support plate 17 is provided, and the outer diameter of the support plate 17 is adapted to the inner diameter of the vertical cylinder 6, so that the support plate 17 can slide stably in the vertical cylinder 6, and at the same time, a pad with a large friction coefficient is provided on the top surface of the support plate 17, so that the support plate 17 can fit tightly with the bottom of the plastic storage tank 1, reducing the probability of the plastic storage tank 1 sliding along the surface of the support plate 17. A telescopic spring 18 is provided at the bottom of the support plate 17. The function of the telescopic spring 18 is to apply an upward force to the support plate 17 through elastic deformation, so that the support plate 17 can push the plastic storage tank 1 that has leakage and light weight to rise. A plastic storage tank 1 is placed on the top of the support plate 17. The plastic storage tank 1 is a traditional polyethylene storage tank. The top of the plastic storage tank 1 is movably threadedly connected to a top cover 2. The function of the top cover 2 is to facilitate the plastic storage tank 1 from the top The top cover 2 is filled with liquid, and a collar 3 is provided on the outside of the top cover 2. The function of the collar 3 is to enable the side panels 5 to be engaged and fixed on both sides of the top cover 2, so that the side panels 5 can rise with the rise of the plastic storage tank 1. The two side walls of the collar 3 are fixedly connected with the side panels 5. The function of the side panels 5 is to increase the contact surface between the plastic storage tank 1 and the vertical cylinder 6, and at the same time, the two side walls of the plastic storage tank 1 can be supported from both sides, thereby reducing the probability of the plastic storage tank 1 tilting in the vertical cylinder 6, thereby helping to improve the stability of the plastic storage tank 1 after being connected to the chassis device. A central column 23 is fixedly connected to the middle of the bottom end of the base plate 7. The function of the central column 23 is to support the center point of the base plate 7 and improve the load capacity of the base plate 7. The triangle at the bottom end of the base plate 7 is fixedly connected with a vertical column 8.The function of the vertical column 8 is to support the bottom end of the base plate 7, so that the force on the base plate 7 can be dispersed outward. The bottom end of the vertical column 8 is fixedly connected with a bottom block 24. The bottom block 24 is made of silica gel and can be disassembled. Its function is to facilitate the leveling of the bottom end of the vertical column 8; A vertical pipe 15 is provided at the remaining corner of the bottom end of the base plate 7. The inner diameter of the vertical pipe 15 is the same as the inner diameter of the transparent pipe 13. A transparent pipe 13 is provided at the top of the vertical pipe 15. The function of the transparent pipe 13 is to facilitate the inspection personnel to check the state of the zinc anode 14, so as to facilitate adjusting the sacrificial anode metal in time according to the consumption of the zinc anode 14 to ensure the anti-corrosion treatment effect of the base frame device. The top of the transparent pipe 13 is movably threadedly engaged with a screw cap 12. The screw cap 12 can be unscrewed and removed from the top of the transparent pipe 13, so that the top of the transparent pipe 13 can be opened, thus facilitating the replenishment of new zinc anodes 14 into the vertical pipe 15 through the transparent pipe 13. A zinc anode 14 is arranged inside the vertical pipe 15. The zinc anode 14 has a "cylindrical" structure, and the outer diameter of the zinc anode 14 is adapted to the inner diameter of the vertical pipe 15, so that the zinc anode 14 can slide down along the inner wall of the vertical pipe 15, enabling a potential difference between the zinc anode 14 and the vertical pipe 15, and further enabling the zinc anode 14 to be consumed as a sacrificial anode. A vertical rod 11 passes through the middle of the screw cap 12. The vertical rod 11 can slide smoothly along the middle of the screw cap 12. The function of the vertical rod 11 is to make the round block 10 contact the top end of the zinc anode 14, so that the change in the length of the zinc anode 14 can drive the position of the vertical rod 11 to change accordingly, thus facilitating the triggering of the contact alarm 27. The top end of the vertical rod 11 is fixedly connected with a round block 10. The function of the round block 10 is to protect the contact alarm 27 and at the same time increase the weight of the top of the vertical rod 11 to facilitate the smooth sliding of the vertical rod 11. A contact alarm 27 is installed at the bottom of the round block 10. The bottom end of the contact alarm 27 protrudes from the bottom surface of the round block 10, so that when the round block 10 contacts the screw cap 12, the contact alarm 27 can be triggered to start. An internal power supply 28 is arranged inside the round block 10. The internal power supply 28 is a rechargeable battery. At the same time, a charging port is arranged on the side of the round block 10, so that the internal power supply 28 can maintain sufficient power to ensure the normal start of the contact alarm 27. A drain pipe 19 penetrates through one side wall of the bottom of the vertical cylinder 6. The drain pipe 19 is made of transparent material, which can facilitate the inspection personnel to observe whether there is liquid in the drain pipe 19, thus facilitating the auxiliary inspection personnel to judge whether the plastic storage tank 1 has leakage. A solenoid valve 20 is installed at the end of the drain pipe 19. The function of the solenoid valve 20 is to facilitate the control of the opening and closing of the drain pipe 19.

[0025] Specifically, the outer wall of the top cover 2 is provided with vertical bars, and the inner wall of the ring 3 is provided with a clamping strip 29. The ring 3 is connected to the top cover 2 through the vertical bars and the clamping strip 29. The function of the clamping strip 29 is to facilitate the ring 3 to be put on the top cover 2 according to the set position, so as to facilitate the side panel 5 on the ring 3 to be inserted into the clamping frame 4 on the side wall of the vertical tube 6.

[0026] Furthermore, the side panel 5 is movably connected to the card frame 4 through the plastic storage tank 1, and the side panel 5 is slidably connected to the vertical tube 6 through the card frame 4, so that the side panel 5 can slide up and down along the inner side of the card frame 4, thereby facilitating the protection of the plastic storage tank 1 by the side panel 5.

[0027] Furthermore, the bottom and middle parts of the vertical column 8 are fixedly connected with the connecting rod 9, and a plurality of diagonal braces 22 are arranged in the middle part of the central column 23. The top ends of the plurality of diagonal braces 22 are respectively fixedly connected with the tops of the outer walls of the vertical column 8 and the vertical tube 15. The diagonal braces 22 can form a stable triangular structure with the vertical column 8 and the vertical tube 15, thereby facilitating the vertical column 8 and the vertical tube 15 to disperse the weight of the base plate 7, and making it easier for the base frame to maintain better stability.

[0028] Furthermore, a through hole 16 is provided at the bottom end of the vertical pipe 15, and the zinc anode 14 is connected to the ground through the through hole 16. The function of the through hole 16 is to enable the zinc anode 14 to contact the ground, thereby facilitating the sacrificial anode and grounding.

[0029] Furthermore, the top of the telescopic spring 18 is fixedly connected to the bottom of the support plate 17, and the bottom of the telescopic spring 18 is fixedly connected to the bottom of the cavity 21. The inner wall of the cavity 21 is provided with an anti-corrosion coating. The function of the telescopic spring 18 is to undergo elastic deformation. At the same time, the deformation of the telescopic spring 18 is large, so that the displacement distance of the side plate 5 sliding up along the card frame 4 is more obvious, so that it is convenient for the inspection personnel to judge whether there is liquid leakage in the plastic storage tank 1 by the change of the bottom position of the side plate 5. Considering that the plastic storage tank 1 will also perform an upward movement, the drainage pipe fittings of the plastic storage tank 1 can be set to a retractable hose form, and it can also be considered not to set the drainage pipe fittings, and the internal raw materials of the plastic storage tank 1 can be discharged by suction discharge.

[0030] Furthermore, a cross frame 25 is fixedly connected to the bottom end of the base plate 7, and a plurality of magnesium anodes 26 are provided on the outer wall of the cross frame 25. The function of the cross frame 25 is to support the magnesium anode 26. The magnesium anode 26 is electrically connected to the zinc anode 14 through the built-in wire of the vertical tube 15, so that the magnesium anode 26 can be electrochemically protected synchronously with the zinc anode 14.

[0031] Furthermore, the interior of the drain pipe 19 is connected to the interior of the cavity 21, so that the liquid that seeps out from the plastic storage tank 1 into the cavity 21 can flow smoothly into the drain pipe 19, thereby facilitating the re-collection of the leaked liquid through the drain pipe 19 and preventing the leaked liquid from dripping directly onto the main structure of the base frame.

[0032] Furthermore, the contact alarm 27 is electrically connected to the built-in power supply 28. The built-in power supply 28 is a detachable structure. The contact alarm 27 includes a physical contact structure and a buzzer part, and a microprocessor is also provided inside. When the contact alarm 27 comes into contact with the screw cap 12, it will be triggered and emit a beeping sound.

[0033] Furthermore, the inside of the transparent tube 13 is communicated with the inside of the vertical tube 15. The transparent tube 13 is fixedly connected to the base plate 7 through the vertical tube 15, so that when the zinc anode 14 is replenished, it can be more convenient and fast, thus facilitating the timely replenishment of the sacrificed zinc anode 14.

[0034] The usage method of this embodiment is as follows: When using this anti-corrosion treatment device for the surface of the plastic storage tank 1 chassis, it is necessary to first place the base plate 7 and the vertical column 8 on a relatively flat ground so that the base plate 7 can be in a position parallel to the ground. Then, the empty plastic storage tank 1 can be placed into the vertical cylinder 6. Next, the top cover 2 at the top of the plastic storage tank 1 is opened, and liquid is filled into the plastic storage tank 1. At this time, as the liquid in the storage tank increases, the weight of the plastic storage tank 1 will increase, causing the pressure of the storage tank on the support plate 17 to increase, prompting the support plate 17 to squeeze the bottom telescopic spring 18, causing the telescopic spring 18 to compress and deform. After the liquid filling is completed, the top cover 2 is tightened. Then, the card strip 29 on the collar 3 is aligned with the vertical strip on the top cover 2 and lowered. At this time, the side plates 5 on both sides of the collar 3 will be inserted into the corresponding card frames 4 on both side walls of the vertical cylinder 6; When there is a liquid leakage at the bottom of the plastic storage tank 1, the liquid will flow from the plastic storage tank 1 into the cavity 21 of the vertical cylinder 6, and then flow along the cavity 21 into the drain pipe 19. As the liquid in the storage tank leaks out, the weight of the storage tank will become lighter, causing the force on the bottom telescopic spring 18 of the support plate 17 to become smaller, and the upward thrust of the telescopic spring 18 to become larger, prompting the support plate 17 to drive the plastic storage tank 1 to move upward. At the same time, the plastic storage tank 1 will drive the collar 3 and the side plates 5 to rise, causing the side plates 5 to move upward along the card frames 4. When the inspection personnel find that the position between the bottom end of the side plate 5 and the card frame 4 has changed, they can check whether there is liquid leaking from the storage tank inside the pipe through the drain pipe 19. If there is liquid of the same color as that in the storage tank, it means that the plastic storage tank 1 has a leakage. Then, the connecting pipe can be connected to the drain pipe 19, and the solenoid valve 20 is opened, so that the liquid in the cavity 21 of the vertical cylinder 6 can be smoothly discharged and collected for treatment, making the liquid leaked from the plastic storage tank 1 not easily fall on the main structure of the chassis, thereby reducing the adverse impact of the storage tank leakage on the anti-corrosion treatment of the chassis; After the chassis is placed, the screw cap 12 can be unscrewed from the top of the transparent tube 13, and then cylindrical zinc anodes 14 adapted to the inner diameter of the vertical tube 15 are successively placed into the top of the opened transparent tube 13, so that the bottom end of the zinc anode 14 can contact the ground through the through hole 16 at the bottom end of the vertical tube 15. Then, the screw cap 12 is tightened. At this time, the bottom end of the vertical rod 11 on the screw cap 12 will contact the top end of the zinc anode 14 in the transparent tube 13. When the zinc anode 14 is consumed through electrochemical protection, the length of the zinc anode 14 in the vertical tube 15 will become shorter, causing the bottom end of the vertical rod 11 to move downward, driving the round block 10 to approach the top of the screw cap 12. When the contact alarm at the bottom of the round block 10 contacts the top surface of the screw cap 12, the contact alarm will emit a beeping sound to remind the inspection personnel and prompt the staff to replenish the sacrificed zinc anode 14 on the chassis in a timely manner.
