Technical Field

[0001] The utility model relates to the technical field of sealing detection, in particular to a sealing safety detection device for a chemical device. Background Art

[0002] In chemical production, chemical equipment has many containers, and chemical raw materials and products are mostly flammable substances with active chemical properties. Once these flammable substances leak, explosions will occur, causing major accidents. Therefore, in order to ensure the sealing of chemical equipment, sealing detection devices are often used.

[0003] In the related art, a chemical device sealing detection device is designed, including a connecting pipe, a main pipe and a float slidably arranged in the main pipe. The connecting pipe is connected to the main pipe, and the outer wall of the connecting pipe is provided with a thread. The connecting pipe is connected to the connecting hole on the chemical device to be measured through the thread, so that the chemical substances in the chemical device enter the main pipe through the connecting pipe and push the float to float up. When no discharge is carried out, the float drops, indicating that there may be a problem with the sealing of the chemical device, which needs to be eliminated in time. In order to facilitate the penetration of the main pipe, an observation window or a measuring sensor is often provided.

[0004] However, in actual use, it is inconvenient to rotate the connecting pipe and the main pipe when installing the detection device installed by thread. In particular, some chemical plants are relatively high, so the main pipe needs to be designed to be longer, which is more inconvenient to rotate. There is still room for improvement in the convenience of installation. Utility Model Content

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a sealing safety detection device for a chemical device. Figure 1 and Figure 2, which comprises an insertion tube 2, a mounting tube 3 and a main column 1. The main column 1 is square. The insertion tube 2 is fixedly arranged on the side wall of the main column 1. The mounting tube 3 is rotatably arranged on the side wall of the main column 1 through a T-shaped block. The mounting tube 3 is sleeved on the outside of the insertion tube 2 and the length of the insertion tube 2 is greater than the length of the mounting tube 3. The outer wall of the mounting tube 3 is provided with a plurality of circles of threads. A sealing gasket 21 is fixedly arranged between the mounting tube 3 and the insertion tube 2. Four rotating handles 32 are fixedly arranged on the outer wall of the mounting tube 3. The rotating handles 32 are arranged between the mounting threads and the main column 1. The main column 1 is provided with a reduction groove 12 connecting the insertion tube 2 and the floating groove 11. The floating groove 11 is arranged in the height direction inside the main column 1. The floating groove 11 is adapted to slide and is provided with a floating ball 4. The side wall of the main column 1 away from the insertion tube 2 is provided with a transparent observation window 13 made of glass. The observation window 13 is used to observe the position of the floating ball 4 in the floating groove 11. During installation, insert the insertion tube 2 and the installation tube 3 into the corresponding holes of the chemical device, rotate the installation tube 3 by the handle and install the installation tube 3 on the chemical device through the connecting thread 31, and connect the inside of the chemical device and the floating groove 11 through the insertion tube 2 and the reduction groove 12. In other embodiments, a rope buckle or other structure can be set to improve the stability of the connection between the main column 1 and the chemical device. After installation, the chemical device is charged, the chemical substance enters the floating groove 11 and pushes the float 4 to rise. The float 4 can be observed through the observation window 13. When the float 4 drops, there is a possibility of leakage of the chemical device in the non-discharging situation, which needs to be checked in time to reduce safety risks. During installation, you only need to rotate the installation tube 3 to improve the convenience of installation. At the same time, by setting the installation tube 3, the possibility of chemical substances leaking from the connection between the detection device and the chemical device is reduced, and the safety performance is further improved.

[0033] In order to reduce the possibility of the float ball 4 being separated from the floating groove 11 and affecting the use, refer to Figure 2 The diameter of the end of the reduction groove 12 connected to the insertion tube 2 is larger than the end connected to the floating groove 11, and the diameter of the end of the reduction groove 12 connected to the floating groove 11 is smaller than the diameter of the float 4. The bottom wall of the column is provided with a replacement groove 15 which is in communication with the bottom wall of the floating groove 11. The float 4 can pass through the replacement groove 15. A replacement bolt 151 is inserted in the replacement groove 15. The replacement bolt 151 is threadedly connected to the replacement groove 15. The float 4 cannot be separated from the floating groove 11 through the reduction groove 12. When replacement is required, the replacement bolt 151 is unscrewed and the float 4 is replaced through the replacement groove 15. In another embodiment, a sealing gasket can be provided at the connection between the replacement bolt 151 and the main column 1 to further improve the sealing of the connection between the replacement bolt 151 and the main column 1.

[0034] To improve the convenience of use, refer to Figure 2 and Figure 3The main column 1 is provided with a mounting block 6 and a mounting bolt 61. The mounting bolt 61 is used to mount the mounting block 6 on the main column 1. The mounting block 6 is provided with a mounting groove 62. The main column 1 can be inserted into the mounting groove 62. A distance sensor 51 is fixedly provided on the inner wall of the mounting groove 62. The top wall of the main column 1 is provided with an observation port 14 that communicates with the floating groove 11. The width of the observation port 14 is smaller than the width of the floating groove 11. The distance sensor 51 is adapted to be inserted into the observation port 14. The side wall of the distance sensor 51 is provided with a sealing pad 511. The bottom wall of the distance sensor 51 is flush with the top wall of the floating groove 11. A controller 5 connected to the signal of the distance sensor 51 is provided in the mounting block 6. An indicator light 52 connected to the signal of the controller 5 is fixedly provided on the top wall of the mounting block 6. The distance sensor 51 measures the distance from the float 4 to the top wall of the floating tank 11. When the float 4 drops, the detection value of the distance sensor 51 drops, and the controller 5 controls the indicator light 52 to light up, reminding the staff to check whether there is a leak in the chemical device. Through intelligent control, there is no need for manual observation of the float 4 at all times, which improves the convenience of use, reduces the possibility of untimely post-leakage treatment, and reduces safety risks.

[0035] The implementation principle of the sealing safety detection device for chemical devices in the embodiment of the present application is as follows: during installation, the insertion tube 2 is adapted to be inserted into the insertion hole of the chemical device, so that the insertion tube 2 and the reduction groove 12 are connected to the inside of the chemical device and the floating groove 11, and the installation tube 3 is inserted into the installation hole of the chemical device, and the installation tube 3 is rotated by rotating the handle 32 so that the connecting thread 31 on the installation tube 3 is connected with the thread of the installation hole, thereby completing the installation. Compared with the detection device in the prior art that needs to rotate the whole, the detection device of the present application is more convenient to install. After installation, the chemical device is fed, and the chemical substance enters the floating groove 11 through the insertion tube 2 and the reduction groove 12 and pushes the floating ball 4 to move up. The distance sensor 51 detects the distance between the floating ball 4 and the top wall of the floating groove 11 in real time. When the chemical device leaks, the value of the distance sensor 51 decreases. At this time, the controller 5 controls the indicator light 52 to light up, reminding the staff to check whether the chemical device has leaked, improve the immediacy of leak detection and processing, and reduce safety risks. At the same time, by setting the installation tube 3, the possibility of chemical substances leaking from the connection between the detection device and the chemical device is reduced, and the safety performance is further improved.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
