Description

Technical Field

[0001] This utility model relates to the technical field of formaldehyde solution ton containers, specifically a leak-proof double-layer structure formaldehyde solution ton container. Background Technology

[0002] Formaldehyde solution ton containers are containers used for storing and transporting formaldehyde solutions. They are usually in ton container size with a capacity of 1000 liters. They are characterized by corrosion resistance, pressure resistance, and good sealing performance. They are mainly used for storing and transporting corrosive liquids such as formaldehyde solutions and liquid alkalis, and are commonly found in the chemical industry.

[0003] Currently, most formaldehyde solution ton containers are single-layer structures, relying mainly on the sealing of the container itself to prevent leakage. If the container is subjected to a large impact, leakage is likely to occur. In the face of complex situations during transportation, such as violent collisions and extreme temperature changes, the formaldehyde solution inside the ton container may evaporate or expand in volume. Excessive pressure can easily lead to container rupture and leakage.

[0004] To address these issues, we offer a leak-proof, double-layered formaldehyde solution container. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a leak-proof double-layer structure formaldehyde solution ton container.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof double-layer formaldehyde solution ton container, comprising an inner tank, a protective mechanism provided on the outer side of the inner tank, the protective mechanism comprising an outer tank, a gas storage tank fixedly connected to the top of the outer tank, a warning light fixedly connected to the upper surface of the gas storage tank, a safety valve fixedly connected to the top of the inner tank, a discharge pipe fixedly connected to the output end of the safety valve, the end of the discharge pipe away from the safety valve fixedly connected to the right side of the gas storage tank, a liquid inlet fixedly connected to the top of the inner tank, a sealing cap threadedly connected to the outer surface of the liquid inlet, a plurality of identical first buffer plates fixedly connected to the outer surface of the inner tank, a plurality of identical second buffer plates fixedly connected to the inner wall of the outer tank, and two buffer springs fixedly connected to the side of each first buffer plate and second buffer plate that are close to each other.

[0007] Furthermore, a fixing ring is fixedly connected to the outer surface of the warning light, and the bottom end of the fixing ring is fixedly connected to the upper surface of the gas storage tank.

[0008] Furthermore, a support frame is fixedly connected to the outer surface of the safety valve, and the bottom surface of the support frame is fixedly connected to the top of the outer barrel.

[0009] Furthermore, a limit ring is fixedly connected to the outer surface of the safety valve input end, and the bottom end of the limit ring is fixedly connected to the top end of the inner barrel.

[0010] Furthermore, a sealing ring is fixedly connected to the outer surface of the discharge pipe, and the end of the sealing ring away from the safety valve is fixedly connected to the right side of the gas storage tank.

[0011] Furthermore, a rubber strip is fixedly connected to the top of the liquid inlet, and the top of the rubber strip is in contact with the inner wall of the sealing cap.

[0012] Compared with existing technologies, this leak-proof double-layer formaldehyde solution tank has the following advantages:

[0013] 1. This utility model features a double-layer structure with an inner and outer barrel. The inner barrel directly holds the formaldehyde solution, while the outer barrel acts as a secondary protective barrier. Even if the inner barrel is accidentally damaged, the outer barrel can temporarily contain the leaked solution, preventing it from directly leaking into the external environment. This structurally reduces the risk of formaldehyde leakage. The first buffer plate on the outer surface of the inner barrel and the second buffer plate on the inner wall of the outer barrel are connected by a buffer spring to form an elastic buffer structure. When the container is subjected to external forces such as collisions and impacts, the buffer spring can absorb and mitigate the impact force, reduce damage, and further reduce the possibility of the inner barrel breaking and leaking.

[0014] 2. This utility model uses a pressure regulating system consisting of a safety valve, a discharge pipe, and a gas storage tank. When the pressure in the inner barrel rises to the set value due to temperature changes, the safety valve automatically opens, allowing excess gas to be temporarily stored in the gas storage tank through the discharge pipe. This prevents the inner barrel from rupturing due to excessive pressure. The gas storage tank can temporarily store the discharged gas, preventing formaldehyde gas from being directly released into the air and causing pollution. At the same time, with the warning light, it can promptly issue a warning in case of abnormal pressure or gas leakage, reminding staff to take action. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] This embodiment provides a leak-proof double-layer formaldehyde solution ton container. This device is used to facilitate the storage and transportation of formaldehyde solution ton containers. Due to the protection of the outer ton container, the leak-proof double-layer structure ton container has stronger impact resistance. At the same time, the internal pressure can be adjusted to reduce the risk of leakage caused by pressure changes. The warning device can also detect potential leakage in time, greatly improving safety performance.

[0022] See Figure 1 and Figure 2 A leak-proof double-layer formaldehyde solution ton container includes an inner tank 1, with a protective mechanism 2 on the outside of the inner tank 1. The protective mechanism 2 includes an outer tank 201, with a gas storage tank 204 fixedly connected to the top of the outer tank 201. A warning light 203 is fixedly connected to the upper surface of the gas storage tank 204, and a fixing ring 3 is fixedly connected to the outer surface of the warning light 203. The bottom end of the fixing ring 3 is fixedly connected to the upper surface of the gas storage tank 204. The fixing ring 3 can fix the position of the warning light 203 to prevent it from shifting or becoming unstable during transportation.

[0023] See Figure 2 and Figure 4 A safety valve 209 is fixedly connected to the top of the inner tub 1. The output end of the safety valve 209 is fixedly connected to the discharge pipe 210. A support frame 4 is fixedly connected to the outer surface of the safety valve 209. The bottom surface of the support frame 4 is fixedly connected to the top of the outer tub 201. The support frame 4 can fix and support the safety valve 209 to prevent it from swaying during use.

[0024] See Figure 2 and Figure 4 The end of the discharge pipe 210 away from the safety valve 209 is fixedly connected to the right side of the gas storage tank 204. The top of the inner barrel 1 is fixedly connected to the liquid inlet 205. The outer surface of the input end of the safety valve 209 is fixedly connected to the limiting ring 6. The bottom end of the limiting ring 6 is fixedly connected to the top of the inner barrel 1. Through the limiting ring 6, the position of the safety valve 209 can be fixedly limited, thus playing a fixed limiting role.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer surface of the liquid inlet 205 is threaded with a sealing cap 202. Several identical first buffer plates 206 are fixedly connected to the outer surface of the inner barrel 1. Several identical second buffer plates 207 are fixedly connected to the inner wall of the outer barrel 201. A sealing ring 5 is fixedly connected to the outer surface of the discharge pipe 210. The end of the sealing ring 5 away from the safety valve 209 is fixedly connected to the right side of the gas storage tank 204. Through the sealing ring 5, the connection between the discharge pipe 210 and the gas storage tank 204 can be sealed and reinforced to prevent gas leakage and pollution to the outside world.

[0026] See Figure 1 , Figure 3 and Figure 4 Each of the first buffer plates 206 and the second buffer plates 207 has two buffer springs 208 fixedly connected to one side of each other. A rubber strip 7 is fixedly connected to the top of the liquid inlet 205. The top of the rubber strip 7 contacts the inner wall of the sealing cover 202. The rubber strip 7 can further improve the sealing performance of the device and enhance its applicability.

[0027] Working principle: During use, first inject formaldehyde solution into the container through inlet 205. Open the sealing cap 202 and slowly inject the formaldehyde solution into the inner container 1 through inlet 205. During injection, carefully control the flow rate to avoid splashing. After injection, close the sealing cap 202, ensuring a tight connection between the cap and inlet 205. At this point, the rubber strip 7 at the top of inlet 205 will be compressed, further enhancing the seal and preventing leakage. During storage, the container should be placed in a flat, dry, and well-ventilated area, avoiding... Avoid direct sunlight and extreme temperature environments. If the ambient temperature changes, the formaldehyde solution in the inner tank 1 may evaporate due to the increased temperature, causing the pressure inside the inner tank 1 to rise. When the pressure rises to the set value of the safety valve 209, the safety valve 209 will automatically open, and the excess gas in the inner tank 1 will be introduced into the gas storage tank 204 through the discharge pipe 210 for temporary storage, to prevent the inner tank 1 from rupturing due to excessive pressure. After the gas is temporarily stored in the gas storage tank 204, if the internal gas concentration reaches a certain threshold or the pressure is abnormal, the warning light 203 will automatically light up to remind the staff to deal with it in time.

[0028] During transportation, the ton container may be subjected to external impacts such as bumps and collisions. At this time, the buffer spring 208 between the first buffer plate 206 on the outer surface of the inner container 1 and the second buffer plate 207 on the inner wall of the outer container 201 will deform to absorb and mitigate the impact force, reduce the direct damage of external forces to the ton container, reduce the risk of the inner container 1 breaking and leaking, and improve its safety.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
