Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic storage tanks, and more specifically, to a glass fiber reinforced plastic anti-corrosion storage tank structure resistant to petrochemical environmental corrosion. Background Art

[0002] FRP storage tank is a new type of composite material, generally composed of substrate, reinforcing material, lining, shell, joint and seal. FRP storage tank has the characteristics of high strength, light weight and long life. Therefore, FRP storage tank is widely used in petrochemical, food, environmental protection and other industries. Because of its high strength, FRP storage tank is mostly used in petrochemical industry.

[0003] A patent application with publication number CN221025495U discloses a corrosion-resistant FRP storage tank, which relates to the field of FRP storage tanks, including a tank body and supporting legs. The tank body includes an anti-corrosion layer, a structural layer and a surface layer. There is a bonding layer between the anti-corrosion layer, the structural layer and the surface layer. There is a flushing groove on the surface of the anti-corrosion layer. The flushing groove is a groove recessed toward the inner side of the anti-corrosion layer. The flushing groove spirally extends downward from the upper side of the inner wall of the tank body to facilitate cleaning the inner wall of the storage tank and prevent the inner wall from being corroded by residual liquid due to incomplete cleaning.

[0004] However, the above technical solution still has some shortcomings. When the FRP storage tank stores petroleum, floating impurities in the petroleum, such as oil stains, water or other insoluble substances, will float on the surface of the petroleum to form an oil floating layer. When the oil floating layer floats on the FRP storage tank for a long time, it will cause corrosion to the inner wall of the FRP storage tank, thereby reducing the service life of the FRP storage tank. In addition, the impurities in the oil floating layer may mix with the petroleum, resulting in a decrease in the purity of the petroleum and affecting the quality of the petroleum.

[0030] Specifically, in the initial state, the oil is placed into the tank body 1 through the liquid inlet, and the lower end of the tank body 1 is provided with a liquid outlet. When the oil in the tank body 1 is left to stand for a period of time, the staff climbs to the upper end of the tank body 1 through the ladder 2. Thereafter, the staff rotates the drive mechanism 4, and the drive mechanism 4 drives the mounting rod 32 to rotate in the annular groove 31, thereby limiting the mounting rod 32 and the drive mechanism 4. The rotation of the mounting rod 32 drives the cleaning component 33 to rotate, and the cleaning component 33 rotates to clean the floating oil layer floating on the surface of the oil, so as to avoid the floating oil layer from floating for a long time, avoid corrosion to the inner wall of the FRP storage tank, and reduce the service life of the FRP storage tank. It also avoids the impurities in the floating oil layer from mixing with the oil, resulting in reduced purity of the oil, which is beneficial to ensure the quality of the oil.

[0031] Please refer to Figure 3 , Figure 4 , Figure 5 The cleaning assembly 33 includes: a cleaning box 331 fixedly connected to the top surface of the mounting rod 32, a liquid inlet is provided on the side wall of the cleaning box 331, and a leakage hole is provided at the bottom of the inner cavity of the cleaning box 331; and a filter plate 332 fixedly installed in the cleaning box 331, the filter plate 332 can be a filter plate 332 made of polypropylene, and the filter plate 332 made of polypropylene can effectively filter floating impurities.

[0032] Specifically, after the oil in the tank body 1 has been standing for a period of time, the driving mechanism 4 is rotated, and the driving mechanism 4 drives the mounting rod 32, the cleaning box 331, and the filter plate 332 to rotate, and the oil and the floating oil layer enter from the liquid inlet, and the filter plate 332 filters the floating oil layer and the oil entering the cleaning box 331, and the floating oil layer remains on the surface of the filter plate 332, and the oil flows down from the filter plate 332 and leaks out from the leakage hole, thereby filtering the floating impurities in the oil and preventing the floating oil layer from corroding the tank body 1.

[0033] Please refer to Figure 2 , Figure 4 , Figure 5, also includes a scraper assembly 34, which is used to clean the floating oil layer on the surface of the filter plate 332, and a sliding groove 341 is opened on the top surface of the cleaning box 331. The scraper assembly 34 includes: a telescopic rod 342 slidably set in the sliding groove 341; a mounting block 343 fixedly connected to the top of the telescopic rod 342; a first fixed plate 344 fixedly installed on the top of the inner cavity of the tank body 1, the first fixed plate 344 is in contact with the mounting block 343; and a scraper 345 fixedly connected to the bottom of the telescopic rod 342, one side of the lower end of the first fixed plate 344 is an inclined surface, the top of the mounting block 343 is an arc surface, and the shape of the first fixed plate 344 is an inclined arc, so that when the first fixed plate 344 is in contact with the mounting block 343, the mounting block 343 drives the telescopic rod 342 and the scraper 345 to move closer to the driving mechanism 4.

[0034] Please refer to Figure 2 , Figure 4 , Figure 5 The scraper assembly 34 also includes: a fixed inclined plate 346 fixedly installed on the inner side wall of the cleaning box 331, fixed plates 347 are fixedly installed on both sides of the telescopic rod 342, and the fixed plates 347 are located between the fixed inclined plate 346 and the filter plate 332; and a spring 348 fixedly installed between the cleaning box 331 and the telescopic rod 342, the spring 348 is arranged in the sliding groove 341, and the spring 348 is used to drive the telescopic rod 342 to move in the sliding groove 341.

[0035] Specifically, after the oil in the tank body 1 has been stationary for a period of time, the driving mechanism 4 is rotated to make the mounting block 343 collide with the first fixed plate 344. One side of the lower end of the first fixed plate 344 is an inclined surface, and the top of the mounting block 343 is an arc surface, so that the first fixed plate 344 and the mounting block 343 are more labor-saving when they collide. The shape of the first fixed plate 344 is an inclined arc. When the first fixed plate 344 and the mounting block 343 collide, the mounting block 343 drives the telescopic rod 342 and the scraper 345 to approach the driving mechanism 4. Mechanism 4 moves, the telescopic rod 342 moves to drive the fixed plate 347 to move, and the fixed inclined plate 346 limits the fixed plate 347, so that the bottom surface of the fixed inclined plate 346 is always in contact with the top surface of the fixed plate 347, so that the scraper 345 is always in contact with the filter plate 332, and then the scraper 345 cleans the floating oil layer on the surface of the filter plate 332. When the first fixed plate 344 does not conflict with the mounting block 343, the spring 1 348 drives the mounting block 343, the telescopic rod 342, the scraper 345, and the fixed plate 347 to reset.

[0038] Please refer to Figure 3 , Figure 6 , and also includes a separation mechanism 5, which is used to collect water settled at the bottom of the tank body 1, and the separation mechanism 5 includes: a disc 51 and a solid disc 52 fixedly installed inside the hollow rotating shaft 41 from top to bottom; a separation tube 53 with one end rotatably connected to the solid disc 52, and the other end of the separation tube 53 is fixedly connected to the bottom of the inner cavity of the tank body 1, and a plurality of water inlet holes 54 are opened at the lower end of the separation tube 53; and a one-way valve 1 55 and a one-way valve 2 56 fixedly installed on the separation tube 53 from top to bottom, the one-way valve 1 55 can only allow water to flow from bottom to top, and the one-way valve 2 56 can only allow water to flow from bottom to top.

[0039] Please refer to Figure 3 , Figure 6 The separation mechanism 5 also includes: a first drive assembly 57 fixedly mounted on the upper end of the separation pipe 53, the first drive assembly 57 is used to transport the water settled to the bottom of the tank body 1 upward; a water outlet pipe 58 located between the fixed plate 52 and the disc 51, one end of the water outlet pipe 58 is fixedly connected to the hollow rotating shaft 41 and communicated with the hollow rotating shaft 41, the other end of the water outlet pipe 58 is fixedly connected to the cleaning box 331 and communicated with the cleaning box 331; and a sewage pipe 59 fixedly connected between the cleaning box 331 and the hollow rotating shaft 41, one end of the sewage pipe 59 is fixedly connected to the cleaning box 331 and communicated with the cleaning box 331, the other end of the sewage pipe 59 is fixedly connected to the hollow rotating shaft 41 and communicated with the hollow rotating shaft 41, and the connecting position of the sewage pipe 59 and the hollow rotating shaft 41 is above the disc 51.

[0041] Specifically, after the oil in the tank body 1 has been standing for a period of time, because the density of water is greater than that of oil and oil is insoluble in water, the water sinks to the bottom and the oil floats on the surface, and the hollow rotating shaft 41 drives the mounting rod 32 and the second fixed plate 574 to rotate, so that the second fixed plate 574 contacts the piston bent rod 573. The top surface of the piston bent rod 573 is an inclined surface, and the bottom surface of the second fixed plate 574 is an inclined surface, and the second fixed plate 574 is an inclined arc shape. When the second fixed plate 574 contacts the piston bent rod 573, the piston bent rod 573 moves to squeeze the second spring 575, so that the inside of the separation tube 53 is in a negative pressure state, thereby causing the water at the bottom of the tank body 1 to enter the inner cavity of the separation tube 53 through the water inlet hole 54. When the second fixed plate 574 does not contact the piston bent rod 573, the second spring 575 drives the piston bent rod 573 to move. The rod 573 is reset, and the one-way valve 56 is installed, so that when the piston bent rod 573 is reset, the water entering the separation tube 53 will not flow downward, and the piston bent rod 573 is reset to make the water in the separation tube 53 flow upward, and the one-way valve 55 prevents the water flowing between the solid disk 52 and the disc 51 from flowing downward. After a certain volume of water between the solid disk 52 and the disc 51, it flows into the part without filter holes of the filter plate 332 in the cleaning box 331 through the outlet pipe 58, thereby flushing the floating oil layer on the surface of the filter plate 332.

[0043] Please refer to Figure 8 , Fig. 9The collecting assembly 72 comprises: a limiting plate 721 rotatably connected to the end of the reciprocating screw 713; and a connecting rod 722 at one end fixedly connected to the bottom of the limiting plate 721, the other end of the connecting rod 722 passes through and is slidably connected to the top of the hollow rotating shaft 41, and a collecting barrel unit 723 is fixedly connected to the lower end of the connecting rod 722, and the collecting barrel unit 723 collects the cleaned floating oil layer sewage; wherein, the collecting barrel unit 723 comprises: a collecting barrel 7231 fixedly connected to the end of the connecting rod 722, and the collecting barrel 7231 is arranged inside the hollow rotating shaft 41; a rubber sheet 7232 attached to the bottom surface of the inner cavity of the collecting barrel 7231, a partial edge of the rubber sheet 7232 is fixedly connected to the bottom surface of the inner cavity of the collecting barrel 7231, and a through hole is opened at the bottom of the collecting barrel 7231, the diameter of the rubber sheet 7232 is greater than the diameter of the through hole, and is located directly above the through hole; a collecting barrel 7231 is opened in the collecting barrel 7 231 side wall, a fixed groove 7234 is provided on the inner wall of the hollow rotating shaft 41; a slide plate 7235 slidably set in the slide groove 7233, and a hole is provided at the lower end of the slide plate 7235; a first magnet 7236 fixedly connected to the side wall of the slide plate 7235, the first magnet 7236 is slidably set in the fixed groove 7234, a second magnet 7237 is fixedly installed on the top of the fixed groove 7234, and the first magnet 7236 can attract the second magnet 7237 to each other; a fixed row pipe 7238 fixedly connected to the lower end of the hollow rotating shaft 41, the fixed row pipe 7238 is connected to the hollow rotating shaft 41; and a collection box 7239 fixedly installed inside the groove 6, when the second magnet 7237 drives the slide plate 7235 to move upward through the first magnet 7236, the collection box 7239 can be connected with the collection bucket 7231 through the hole on the slide plate 7235.

[0044] Specifically, the rotation of the hollow shaft 41 drives the first fixed wheel to rotate, the first fixed wheel drives the transmission belt 712 to rotate, the transmission belt 712 drives the second fixed wheel and the shaft body 711 to rotate, and the rotation of the shaft body 711 causes the reciprocating screw 713 to reciprocate up and down. When the reciprocating screw 713 moves downward, it drives the collecting assembly 72 to move downward. When the collecting barrel 7231 moves to the lower end, since the rubber sheet 7232 has a certain elasticity and flexibility, the floating oil layer sewage lifts the rubber sheet 7232, and the floating oil layer sewage enters the collecting barrel 7231 from the through hole at the bottom of the collecting barrel 7231. When the reciprocating screw 713 moves upward, it drives the limit plate 721, the connecting rod 722, and the collecting barrel unit 723 to move upward. The water relies on gravity to drive the rubber sheet 7232 to fit the bottom surface of the collecting barrel 7231, so that the water in the collecting barrel 7231 will not flow out from the bottom through hole. A fixed hole is provided on the side wall of 231. When the collecting barrel 7231 moves to a certain position, the second magnet 7237 adsorbs the first magnet 7236, so that the first magnet 7236 drives the slide plate 7235 to move slowly upward in the slide groove 7233. When the collecting barrel 7231 moves to the uppermost end, the second magnet 7237 and the first magnet 7236 are completely adsorbed, and the first magnet 7236 drives the slide plate 7235 to move to the uppermost end of the slide groove 7233. At this time, the fixed hole of the collecting barrel 7231, the hole of the slide plate 7235 and the fixed discharge pipe 7238 are connected, and the floating oil layer sewage in the collecting barrel 7231 is discharged into the collecting box 7239. The staff treats the floating oil layer sewage in the collecting box 7239, thereby cleaning the floating oil layer cleaned by the cleaning mechanism 3, avoiding manual cleaning of the floating oil layer in the cleaning mechanism 3 again, thereby saving the cleaning time of the floating oil layer.
