Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-strength thermoplastic steel-lined plastic storage tanks, and more specifically, to a high-strength thermoplastic steel-lined plastic storage tank. Background Art
[0002] In the existing technology, high-strength thermoplastic steel-lined plastic storage tanks are widely used for liquid storage in the chemical, food and other industries due to their corrosion resistance and good sealing performance. However, when these tanks are used to store volatile raw materials, a technical problem may be encountered. Volatile raw materials may vaporize during storage, producing a large amount of gas, causing the pressure in the tank to increase. If the pressure in the tank exceeds the design tolerance of the tank, and there is no appropriate pressure relief measure, it may cause damage to the tank or even a leakage accident, which will seriously affect the safety of use.
[0003] Existing high-strength thermoplastic steel-lined plastic storage tanks may not take into account the characteristics of volatile raw materials during design, and therefore may lack effective pressure relief devices or have insufficient pressure relief capacity. When the pressure inside the tank is too high, if the pressure is not relieved in time, it will not only threaten the structural integrity of the tank, but may also cause safety accidents such as explosions or leaks, causing serious harm to personnel and the environment. In addition, excessive pressure may also affect the sealing performance of the tank, resulting in the loss of raw materials and environmental pollution. Utility Model Content

[0015] (III) Beneficial effects
[0016] Compared with the prior art, the utility model provides a high-strength thermoplastic steel-lined plastic storage tank, which has the following beneficial effects:
[0017] 1. The design of the pressure relief mechanism enables the high-strength thermoplastic steel-lined plastic storage tank to quickly and effectively relieve pressure when the internal pressure is too high. Through the cooperation of the pressure relief pipe and the regulating mechanism, when the pressure in the tank exceeds the set value, the elastic force of the spring is overcome, and the seal between the sealing disc and the sealing sleeve is released, thereby allowing the medium to be released to the external collection equipment through the pressure relief pipe. This design avoids damage to the tank structure or leakage accidents caused by excessive pressure, and ensures the safety of the tank when storing volatile raw materials.
[0018] 2. The regulating mechanism provides fine control over the pressure relief flow and pressure. Through the cooperation of the rotating head and the intermediate rod, the operator can adjust the position of the guide rod, thereby driving the relative position of the threaded sleeve and the adjusting disk to change. This design allows the pressure relief flow to be adjusted according to actual needs. When the distance between the adjusting disk and the adjusting sleeve increases, the pressure relief flow increases; otherwise, it decreases. In addition, when the storage tank needs to be completely closed, the adjusting disk can be fitted on the adjusting sleeve and a double-layer seal is achieved through the closing ring, ensuring the sealing performance of the storage tank in a non-pressure relief state and preventing leakage of the medium.
[0019] 3. The receiving mechanism plays an important supporting and collecting role in the pressure relief process of the storage tank. The support frame not only provides a stable installation platform for the storage tank, but also facilitates the operator to monitor and handle the pressure relief medium, ensuring the reliability and efficiency of the entire pressure relief system.

[0029] See also Figure 1-5 A high-strength thermoplastic steel lined plastic storage tank comprises an outer shell 1, which is connected to external equipment. A pressure relief mechanism is arranged on the outer shell 1, and the pressure relief mechanism comprises a pressure relief pipe 2, an adjusting mechanism, an intermediate pipe 3, an intermediate rod 4, an adjusting sleeve 5, a cone head 6, an adjusting disk 7, a threaded sleeve 8, a guide rod 9 and a receiving mechanism. The pressure relief pipe 2 is installed on the outer shell 1, and the adjusting mechanism is installed on the pressure relief pipe 2. The adjusting mechanism is cooperatively connected to the pressure relief pipe 2 and the intermediate pipe 3. The intermediate rod 4 is slidably connected in the intermediate pipe 3. The cone head 6 is installed on the intermediate rod 4, and the cone head 6 fits on the intermediate pipe 3. The adjusting sleeve 5 is installed in the pressure relief pipe 2. The threaded sleeve 8 is threadedly connected to the intermediate pipe 3. The adjusting disk 7 is installed on the threaded sleeve 8. The guide rod 9 is installed on the cone head 6. A guide hole 10 is opened on the adjusting disk 7. The guide rod 9 is slidably connected in the guide hole 10. The receiving mechanism is installed on the outer shell 1. A fixed disk 11 is coaxially provided on the intermediate pipe 3. A rotating head 12 is provided on the middle rod 4, and the rotating head 12 is attached to the fixed disk 11. The adjusting mechanism includes a sealing sleeve 13 and a sealing disk 14. The sealing sleeve 13 is installed on the pressure relief pipe 2, and the sealing disk 14 is installed on the intermediate pipe 3, and the sealing disk 14 is attached to the sealing sleeve 13. A threaded tube 15 is threaded on the pressure relief pipe 2, and the intermediate pipe 3 is slidably connected in the threaded tube 15. A rotating disk 16 is coaxially provided on the threaded tube 15, and an anti-slip groove 17 is provided on the side wall of the rotating disk 16. A spring 18 is provided on the threaded tube 15, and the spring 18 abuts on the sealing disk 14. A closing ring 19 is coaxially provided on the threaded tube 15. An external pipe 20 is provided on the side wall of the pressure relief pipe 2, and the external pipe 20 is connected to an external collection device. The receiving mechanism includes a support frame 21 and a discharge port 22. The support frame 21 is installed on the external device, and the shell 1 is installed on the support frame 21, and the discharge port 22 is installed on the lower end surface of the shell 1.
[0030] In this embodiment, when the pressure in the housing 1 is too large and needs to be relieved, first the pressure in the housing 1 exceeds the elastic force of the spring 18, so the seal between the sealing disk 14 and the sealing sleeve 13 will be released, and then the adjusting disk 7 will move toward the adjusting sleeve 5. When the adjusting disk 7 moves toward the adjusting sleeve 5, the flow rate will be reduced, and then a balance will be reached, and then the pressure will be relieved to the external collection device through the external pipe 20, thereby completing the pressure relief process. When the flow rate of the leakage flow needs to be adjusted, first, the rotating head 12 can be rotated to drive the guide rod 9 to rotate under the action of the intermediate rod 4 and the cone head 6. Since the guide rod 9 is inserted into the adjusting disk 7, the threaded sleeve 8 on the adjusting disk 7 will be driven to rotate along the thread of the intermediate pipe 3, so that the initial position of the adjusting disk 7 and the adjusting sleeve 5 can be changed. When the adjusting disk 7 is farther away from the adjusting sleeve 5, the flow rate of the leakage flow is greater, so corresponding adjustments are made. When complete sealing is required, the adjusting disk 7 is first rotated to fit on the adjusting sleeve 5, and the threaded tube 15 is rotated to make the closing ring 19 contact the sealing sleeve 13, thereby completing the double-layer sealing, and then completing the sealing process.
[0031] More specifically, when the pressure of the pressure relief needs to be adjusted, the threaded tube 15 is first rotated to change the position between the threaded tube 15 and the pressure relief tube 2, and then the compression degree of the spring 18 is changed, thereby changing the pressure of the pressure relief, thereby ensuring safety of use.
[0032] In summary, when the overall device is in use or running: when the pressure in the housing 1 is too high and needs to be relieved, first the pressure in the housing 1 exceeds the elastic force of the spring 18, thereby releasing the seal between the sealing disk 14 and the sealing sleeve 13, and then the adjusting disk 7 moves toward the adjusting sleeve 5. When the adjusting disk 7 moves toward the adjusting sleeve 5, the flow rate will be reduced, and then a balance will be reached, and then the pressure will be relieved to the external collection device through the external pipe 20, thereby completing the pressure relief process. When the flow rate of the leakage flow needs to be adjusted, first the rotating head 12 can be rotated through the intermediate rod 4 The guide rod 9 is driven to rotate under the action of the cone head 6. Since the guide rod 9 is inserted into the adjusting disk 7, the threaded sleeve 8 on the adjusting disk 7 will be driven to rotate along the thread of the intermediate tube 3. Therefore, the initial positions of the adjusting disk 7 and the adjusting sleeve 5 can be changed. The farther the adjusting disk 7 is from the adjusting sleeve 5, the greater the leakage flow rate. Therefore, corresponding adjustments are made. When complete sealing is required, the adjusting disk 7 is first rotated to fit the adjusting sleeve 5, and the threaded tube 15 is rotated to make the closing ring 19 contact the sealing sleeve 13, thereby completing the double-layer seal and then completing the sealing process.
[0033] When the pressure of the pressure relief needs to be adjusted, the threaded tube 15 is first rotated to change the position between the threaded tube 15 and the pressure relief tube 2, and then the compression degree of the spring 18 is changed, thereby changing the pressure of the pressure relief, thereby ensuring the safety of use.
