Description

Technical Field

[0001] The utility model relates to the field of storage tanks, in particular to a double-stacked combined storage tank. Background Art

[0002] With the advancement of industrial development and modernization, the demand for storage tanks is increasing. Traditional single-layer storage tanks have some problems during use, such as susceptibility to external environmental influences and prone to leakage. These problems pose serious challenges to the safety of stored materials and environmental protection. Therefore, double-layer storage tanks have gradually become the dominant product in the storage tank market. They have advantages such as strong sealing, wide adaptability, high safety, and corrosion resistance, and are widely used in the petroleum, chemical, pharmaceutical and other fields.

[0003] At present, the double-layer horizontal storage tanks used in the industry include an outer tank body arranged horizontally, an inner tank body arranged horizontally inside the outer tank body, and a gap between the outer wall of the inner tank body and the inner wall of the outer tank body. There are a feed pipe and a discharge pipe on the inner tank body, and the outer ends of the feed pipe and the discharge pipe respectively pass through the side wall of the outer tank body and extend outward, and the feed pipe and the discharge pipe are both sealed with the side wall of the outer tank body. There is a feed valve on the feed pipe and a discharge valve on the discharge pipe. During the use of this type of storage tank, when the inner tank body or the outer tank body leaks, the user cannot immediately know, which poses a safety hazard. Moreover, conventional double-layer horizontal storage tanks directly add materials to the inner end of the inner tank, which has no buffering effect and will cause a large impact force, causing damage or deformation of the inner tank, reducing the service life of the equipment.

[0004] Therefore, those skilled in the art provide a double-stacked combined storage tank to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a double-stacked combined storage tank. The utility model can observe whether the inner tank and the outer tank are leaking, and the feed port of the utility model is equipped with a buffer mechanism to prevent the inner tank from being damaged.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The air bag is fixedly mounted on the top of the air bag, and the air bag is piped with a plurality of pipes extending along the length of the air bag so as to prevent the air bag from leaking out.

[0008] Furthermore, the two supporting legs are fixedly arranged on the inner side of the outer tank body near the bottom end, and the gas generating device is fixedly arranged on the other side of the upper end of the bottom plate.

[0009] Furthermore, the discharge pipe passes through the outer tank body and reaches the lower end of the outer side of the outer tank body, and the feed pipe passes through the outer tank body and reaches the upper end of the outer tank body.

[0010] Furthermore, valves are fixedly provided on the outer ends of the vacuum pipe, air inlet pipe, feed pipe and discharge pipe.

[0011] Furthermore, the feed pipe and the discharge pipe are both sealed with the side wall of the outer tank body, the inner tank body is made of steel, and the outer tank body is made of reinforced glass fiber.

[0012] Furthermore, the four fixing rods are fixedly arranged at the lower end of the feed pipe, and the fixing box is fixedly arranged at the lower end of the feed pipe.

[0013] Furthermore, a plurality of the guide grooves are opened at the lower end of the feed pipe, and the movable block is movably arranged at the lower end of the feed pipe.

[0014] The utility model has the following beneficial effects:

[0015] 1. The double-layer stacked combined storage tank proposed by the present invention is used by first opening the feed pipe to feed the material to be stored into the tank body, then closing the feed pipe, then opening the vacuum valve, starting the vacuum device, extracting the air in the outer tank body, then closing the vacuum valve, opening the air inlet valve, starting the nitric oxide gas generator, and pouring nitric oxide into the outer tank body, finally closing the nitric oxide gas generator and the air inlet valve. When the inner tank body leaks, the liquid in the inner tank body enters the outer tank body from the leak, and due to gravity, the liquid in the inner tank body enters the outer tank body from the leak. The leaked material enters the observation tube from the bottom of the groove. The user can tell that the inner tank has leaked by observing the transparent observation tube. When the outer tank leaks, air from the air can enter through the leak. Since there is nitric oxide in the inner tank, the nitric oxide encounters the leaked air and causes the color of the outer tank to change. A transparent observation port is opened on one side of the outer tank. The user can tell that the outer tank has leaked by observing the transparent observation port. Liquid leakage from the inner tank can be detected in time through the transparent observation tube, while leakage of the outer tank will be warned by color change. This design allows immediate measures to be taken when a leak occurs, reducing safety risks.

[0016] 2. The utility model proposes a double-stacked combined storage tank. When the material enters the inner tank body, it will first fall on the upper end of the movable block. The spring design at the lower end of the movable block can effectively buffer the impact force of the entering material, prevent damage caused by the rapid fall of the material, and extend the service life of the equipment. The guide groove can divert the material and finally flow into the inner tank body. The design of the guide groove allows the material to be evenly diverted before flowing into the inner tank body, avoiding concentrated accumulation, thereby reducing the blockage and accumulation of the material and ensuring that the material can flow smoothly into the inner tank body.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1-Figure 5 , an embodiment provided by the utility model:

[0028] A double-stacked combined storage tank includes a bottom plate 7, an inner tank body 8 and a buffer mechanism 10. The upper end of the bottom plate 7 is fixedly provided with a fixing ring 6 on both sides. The inner end of the fixing ring 6 is fixedly provided with an outer tank body 1. A vacuum tube 2 is fixedly provided on one side of the upper end of the outer tank body 1. A vacuum pump 3 is fixedly provided on the upper end of the vacuum tube 2. An air inlet pipe 4 is fixedly provided on the other side of the upper end of the outer tank body 1. A gas generating device 5 is fixedly provided on the output end of the air inlet pipe 4. A groove 11 is provided on the bottom end of the outer tank body 1. A transparent observation tube 12 is fixedly provided on one side of the lower end of the outer tank body 1. A feeding pipe 9 is fixedly provided on one side of the upper end of the inner tank body 8. A discharge pipe 13 is fixedly provided, and support feet 14 are fixedly provided on both sides of the lower end of the inner tank body 8. The two support feet 14 are fixedly provided on the inner side of the outer tank body 1 near the bottom end. The gas generating device 5 is fixedly provided on the other side of the upper end of the bottom plate 7. The discharge pipe 13 passes through the outer tank body 1 and leads to the outer side of the outer tank body 1 near the lower end. The feed pipe 9 passes through the outer tank body 1 and leads to the upper end of the outer tank body 1. The outer ends of the vacuum tube 2, the air inlet pipe 4, the feed pipe 9 and the discharge pipe 13 are fixedly provided with valves. The feed pipe 9 and the discharge pipe 13 are sealed with the side wall of the outer tank body 1. The inner tank body 8 is made of steel and the outer tank body 1 is made of reinforced glass fiber.

[0029] Specifically, when in use, first open the feed pipe 9 and feed the material to be stored into the tank body. Then, close the feed pipe 9, then open the vacuum valve, start the vacuum device, and extract the air in the outer tank body 1. After that, close the vacuum valve, open the air inlet valve, start the nitric oxide gas generating device 5, and pour nitric oxide into the outer tank body 1. Finally, close the nitric oxide gas generating device 5 and the air inlet valve. When the inner tank body 8 leaks, the liquid contained in the inner tank body 8 enters the outer tank body 1 from the leak. Due to gravity, the leaked material flows out from the concave part. The bottom of the groove 11 flows into the observation tube. By observing the transparent observation tube 12, the user can know that the inner tank 8 has leaked. When the outer tank 1 leaks, air from the atmosphere can enter through the leak. Since the inner tank 8 contains nitric oxide, the nitric oxide encounters the leaked air, causing the color of the outer tank 1 to change. A transparent observation port is provided on one side of the outer tank 1. The user can know that the outer tank 1 has leaked by observing the transparent observation port. Liquid leakage from the inner tank 8 can be detected immediately through the transparent observation tube 12, while leakage from the outer tank 1 is warned by the color change. This design allows immediate action when a leak occurs, reducing safety risks.

[0030] Reference Figure 6 、 Figure 7 The buffer mechanism 10 includes a fixed box 1001, four fixed rods 1002 are fixedly provided at the outer end of the fixed box 1001, a plurality of guide grooves 1003 are opened at the upper end of the fixed box 1001, a spring 1004 is provided in the groove at the upper end of the fixed box 1001, a movable block 1005 is fixedly provided at the upper end of the spring 1004, the four fixed rods 1002 are fixedly provided at the lower end of the feed pipe 9, the fixed box 1001 is fixedly provided at the lower end of the feed pipe 9, a plurality of guide grooves 1003 are opened at the lower end of the feed pipe 9, and the movable block 1005 is movably provided at the lower end of the feed pipe 9.

[0031] Specifically, when the material enters the inner tank body 8, it will first fall on the upper end of the movable block 1005. The spring 1004 at the lower end of the movable block 1005 is designed to effectively buffer the impact force of the entering material, prevent damage caused by the rapid fall of the material, and extend the service life of the equipment. The guide groove 1003 can divert the material, and finally flow into the inner tank body 8. The design of the guide groove 1003 allows the material to be evenly diverted before flowing into the inner tank body 8, avoiding concentrated accumulation, thereby reducing the blockage and accumulation of the material, and ensuring that the material can flow smoothly into the inner tank body 8.

[0032] Working principle: when in use, first open the feed pipe 9 and feed the material to be stored into the tank body, then close the feed pipe 9, then open the vacuum valve, start the vacuum device, and extract the air in the outer tank body 1, then close the vacuum valve, open the air inlet valve, start the nitric oxide gas generator 5, and pour nitric oxide into the outer tank body 1, finally, close the nitric oxide gas generator 5 and the air inlet valve. When the inner tank body 8 leaks, the liquid contained in the inner tank body 8 enters the outer tank body 1 from the leak. Due to gravity, the leaked material enters the observation tube from the bottom of the groove 11. The user can know that the inner tank body 8 has leaked by observing the transparent observation tube 12. When the outer tank body 1 leaks, air in the air can enter from the leak. Since there is nitric oxide in the inner tank body 8, the nitric oxide encounters the leaked air and causes the color of the outer tank body 1 to change. A transparent observation port is provided on one side of the outer tank body 1. The user can know that the outer tank body 1 has leaked by observing the transparent observation port.

[0033] Secondly, when the material enters the inner tank body 8, it will first fall on the upper end of the movable block 1005. Since there is a spring 1004 at the lower end of the movable block 1005, the entering material can be buffered, and the guide groove 1003 can divert the material, and finally it will flow into the inner tank body 8.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
