Description

Technical Field

[0001] This utility model relates to the field of isobutylene storage technology, and in particular to an isobutylene storage tank. Background Technology

[0002] Isobutylene's main functions are asphyxiation, mild anesthesia, and mild irritation. It can form explosive mixtures with air. It poses a risk of combustion and explosion when exposed to heat sources and open flames. It may undergo a violent polymerization reaction when heated. It reacts violently with oxidizers. As the gas is heavier than air, it can diffuse to considerable distances at lower levels and will ignite upon contact with an ignition source.

[0003] In the prior art, when storing isobutylene, the sealing and opening of the feed pipe and the discharge pipe are controlled by valves. However, it is impossible to detect the valves and the feed pipes and discharge pipes. According to the content of Chinese Utility Model Patent No. CN205972501U, after the valves have been used for a long time, isobutylene leakage is likely to occur at the feed pipes and discharge pipes due to wear and tear or other factors, thereby affecting the safety of isobutylene storage.

[0004] To address the aforementioned technical deficiencies, a solution is proposed that allows for the detection of the feed pipe and discharge pipe during isobutylene storage to prevent leakage. Utility Model Content

[0005] The purpose of this invention is to provide an isobutylene storage tank to solve the problems mentioned above.

[0006] The objective of this utility model can be achieved through the following technical solution: An isobutylene storage tank includes a storage tank body and a feed pipe. A feed pipe is fixedly connected to the top of the storage tank body, and a discharge pipe is fixedly connected to the bottom of the storage tank body. Both the feed pipe and the discharge pipe are equipped with electrically controlled valves on their side walls. The feed pipe and the discharge pipe are both connected to the storage tank body. Monitoring cylinders are provided on both the upper and lower sides of the storage tank body. The feed pipe and the discharge pipe are respectively located in the two monitoring cylinders. One end of the feed pipe and the discharge pipe is fixedly connected with an internal threaded ring. Both monitoring cylinders have through holes on their side walls. Both internal threaded rings are threaded with sealing heads. The side walls of the two sealing heads abut against the side walls of the two monitoring cylinders. Both sealing heads have handles fixedly connected to their side walls. Both monitoring cylinders are equipped with second pressure sensors. One end of the feed tube is fixedly connected to a connector, which is adapted to an internal threaded ring.

[0007] Preferably, a first pressure sensor is fixedly connected to the top of the storage tank body, and a pressure relief valve is provided on the top of the storage tank body.

[0008] Preferably, the storage tank body is configured with three layers: the outermost layer is a heat insulation layer, the middle layer is a tank base layer, and the innermost layer is an anti-static layer.

[0009] Preferably, the storage tank body is fixedly connected to four feet at the bottom, and the bottom diameter of each of the four feet is larger than the top diameter.

[0010] Preferably, a rubber pad is fixedly connected to one end of each of the two monitoring cylinders, and the two rubber pads are respectively located between the two monitoring cylinders and the two sealing heads.

[0011] Preferably, both ends of the storage tank body are provided with T-shaped positioning ring grooves, and one end of each of the two monitoring cylinders is fixedly connected with a sealing ring. The two monitoring cylinders and the two sealing rings are slidably connected in the two T-shaped positioning ring grooves, and the two sealing rings abut against the side walls of the two T-shaped positioning ring grooves.

[0012] The beneficial effects of this utility model are: When storing or introducing isobutylene into the storage tank, a sealing head can be used to seal one side of the monitoring cylinder, sealing the feed pipe and discharge pipe within two monitoring cylinders. This allows for the monitoring of the feed pipe and discharge pipe, preventing leaks caused by wear of the electronically controlled valves or other factors after prolonged use. This improves the safety of isobutylene storage. Furthermore, when introducing isobutylene into the storage tank, a connecting head can be used to compress and seal the connection between the feed pipe and the guide pipe, preventing leakage and further enhancing the safety of introducing isobutylene into the storage tank. By using a sealing head to seal the top of the monitoring cylinder, the sealing head can also squeeze and fix the monitoring cylinder. When the electric control valve or the second pressure sensor is damaged, the monitoring cylinder can be disassembled by removing the sealing head and then lifting the monitoring cylinder, which facilitates the replacement and maintenance of the electric control valve or the second pressure sensor.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: The application background of this utility model is based on isobutylene storage. However, it is impossible to detect leaks at the feed pipe and discharge pipe during isobutylene storage. The technical solution of this utility model is to solve the problem of how to detect leaks at the feed pipe and discharge pipe of the storage tank during isobutylene storage, so as to prevent isobutylene leakage and improve the safety of isobutylene storage. Please see Figures 1-4 As shown, this embodiment is an isobutylene storage tank, including a storage tank body 1 and a feed pipe 5. A feed pipe 15 is fixedly connected to the top of the storage tank body 1, and a discharge pipe 7 is fixedly connected to the bottom of the storage tank body 1. Both the feed pipe 15 and the discharge pipe 7 are provided with electrically controlled valves 16 on their side walls. The feed pipe 15 and the discharge pipe 7 are both connected to the inside of the storage tank body 1. Monitoring cylinders 2 are provided on both the upper and lower sides of the storage tank body 1. The feed pipe 15 and the discharge pipe 7 are respectively located in the two monitoring cylinders 2. One end of the feed pipe 15 and the discharge pipe 7 is fixedly connected with an internal threaded ring 11. Both monitoring cylinders 2 have through holes on their side walls. Both internal threaded rings 11 are threadedly connected with sealing heads 10. The side walls of the two sealing heads 10 are respectively abutted against the side walls of the two monitoring cylinders 2. Both sealing heads 10 are fixedly connected with handles 9 on their side walls. Both monitoring cylinders 2 are provided with second pressure sensors 14. One end of the feed tube 5 is fixedly connected to a connector 4, which is adapted to the internal threaded ring 11.

[0017] A first pressure sensor 13 is fixedly connected to the top of the storage tank body 1. A pressure relief valve 12 is provided on the top of the storage tank body 1. The first pressure sensor 13 can monitor the pressure inside the storage tank body 1, and the pressure relief valve can be used to release the pressure inside the storage tank body 1.

[0018] The storage tank body 1 adopts a three-layer structure: the outermost layer is a heat insulation layer, the middle layer is a tank body base layer, and the innermost layer is an antistatic layer. This is used to improve the heat insulation and antistatic performance of the storage tank body 1, reduce the influence of external temperature on isobutylene, and prevent isobutylene from generating static sparks during the flow process, which could lead to an explosion.

[0019] The storage tank body 1 is fixedly connected to four feet 6 at the bottom. The bottom diameter of the four feet 6 is larger than the top diameter, which is used to provide stable support for the storage tank body 1.

[0020] Each of the two monitoring cylinders 2 is fixedly connected to one end with a rubber pad 17. The two rubber pads 17 are located between the two monitoring cylinders 2 and the two sealing heads 10, respectively, to improve the sealing between the two monitoring cylinders 2 and the two sealing heads 10. Reference Figures 1-4 As shown, during use, by screwing one end of the sealing head 10 into the internal threaded ring 11, the bottom of the sealing head 10 abuts against the top side wall of the monitoring cylinder 2, thereby sealing the top of the monitoring cylinder 2 and creating a sealed state inside the monitoring cylinder 2. The pressure inside the monitoring cylinder 2 can be detected by the second pressure sensor 14 to prevent isobutylene leakage at the feed pipe 15 and the electrically controlled valve 16. When introducing isobutylene into the storage tank body 1, by screwing the connector 4 at one end of the feed pipe 5 into the internal threaded ring 11, the connection... The head 4 side wall abuts against the top side wall of the monitoring cylinder 2, and isobutylene is introduced into the storage tank body 1 through the guide pipe 5 and the feed pipe 15. At this time, the connection between the guide pipe 5 and the feed pipe 15 is located inside the monitoring cylinder 2. When isobutylene is introduced into the storage tank body 1, the second pressure sensor 14 can also detect the connection between the guide pipe 5 and the feed pipe 15 to prevent isobutylene leakage between the guide pipe 5 and the feed pipe 15. Through the two monitoring cylinders 2, the feed pipe 15 and the discharge pipe 7 can be detected at the same time. As can be seen from the above operation process, when storing or introducing isobutylene into the storage tank body 1, the sealing head 10 can seal one side of the monitoring cylinder 2, so that the feed pipe 15 and the discharge pipe 7 are sealed in the two monitoring cylinders 2, and the feed pipe 15 and the discharge pipe 7 are detected to prevent air leakage caused by wear of the electric control valve 16 or other factors after long-term use, thereby improving the safety of isobutylene during storage. The connecting head 4 can connect the guide pipe 5 and the feed pipe 15. The connecting head 4 is pressed against the top of the monitoring cylinder 2 to seal the monitoring cylinder 2, so that the connection between the guide pipe 5 and the feed pipe 15 can be detected when isobutylene is introduced into the storage tank body 1 to prevent isobutylene leakage and improve the safety of isobutylene when it is introduced into the storage tank body 1. Example 2: Please refer to Figures 1-4As shown, both ends of the storage tank body 1 are provided with T-shaped positioning ring grooves 3, and one end of each of the two monitoring cylinders 2 is fixedly connected with a sealing ring 8. The two monitoring cylinders 2 and the two sealing rings 8 are slidably connected in the two T-shaped positioning ring grooves 3 respectively, and the two sealing rings 8 abut against the side walls of the two T-shaped positioning ring grooves 3. The monitoring cylinder 2, along with the sealing ring 8, can be inserted into the T-shaped positioning ring groove 3 through the T-shaped positioning ring groove 3. The sealing head 10 is screwed into the internal threaded ring 11 to squeeze the monitoring cylinder 2, so that the monitoring cylinder 2 and the sealing ring 8 are firmly squeezed into the T-shaped positioning ring groove 3. The T-shaped positioning ring groove 3 increases the contact area between the monitoring cylinder 2 and the T-shaped positioning ring groove 3, thereby improving the sealing performance between the monitoring cylinder 2 and the T-shaped positioning ring groove 3. By using the sealing head 10 to seal the top of the monitoring cylinder 2, the sealing head 10 can also squeeze and fix the monitoring cylinder 2. When the electric control valve 16 or the second pressure sensor 14 is damaged, the sealing head 10 can be removed and the monitoring cylinder 2 can be lifted to disassemble the monitoring cylinder 2, thereby facilitating the replacement and maintenance of the electric control valve 16 or the second pressure sensor 14.

[0021] Combining Embodiments 1 and 2, it can be seen that, on the one hand, when storing isobutylene, the sealing head 10 can seal one side of the monitoring cylinder 2, sealing the feed pipe 15 and the discharge pipe 7 within the two monitoring cylinders 2, allowing for the detection of the feed pipe 15 and the discharge pipe 7, preventing air leakage caused by wear of the electronically controlled valve 16 or other factors after prolonged use, thereby improving the safety of isobutylene during storage; on the other hand, by using the sealing head 10 to seal the top of the monitoring cylinder 2, the sealing head 10 can also compress and fix the monitoring cylinder 2, so that if the electronically controlled valve 16 or the second pressure sensor 14 is damaged, the sealing head 10 can be removed, and then the monitoring cylinder 2 can be lifted to disassemble it, thus facilitating the replacement and maintenance of the electronically controlled valve 16 or the second pressure sensor 14.

[0022] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
