Description

Technical Field

[0001] This utility model belongs to the technical field of online monitoring devices for acid mist exhaust gas, and specifically relates to an online pH monitoring device for acid mist exhaust gas. Background Technology

[0002] Acid mist is an acidic substance between flue gas and water mist, and it has strong corrosive properties. Acid mist exhaust gas is generated in manufacturing plants, so it is necessary to use an online pH meter for monitoring acid mist exhaust gas. However, existing online pH meters for acid mist exhaust gas are generally fixed on a column and cannot be flexibly raised or lowered. When the online pH meter for acid mist exhaust gas is damaged and needs to be repaired, personnel need to use a ladder to climb to a high position for repair. This operation is cumbersome, and the risk of personnel climbing to a high position is also high. Therefore, we propose an online pH monitoring device for acid mist exhaust gas. Summary of the Invention

[0003] The purpose of this utility model is to provide an online pH monitoring device for acid mist exhaust gas. By designing a base, hollow column, online acid mist exhaust gas monitor, and lifting component, the online acid mist exhaust gas monitor can be lowered by rotating the upright when it is damaged and needs repair after it is installed in a designated position. This eliminates the need for personnel to climb with a ladder for maintenance, reducing the risk factor. The overall structure is compact and easy to operate, bringing convenience to the maintenance work of the staff.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an online pH monitoring device for acid mist exhaust gas, comprising a base, a hollow column at the top of the base, an online acid mist exhaust gas monitor installed on one side of the top of the hollow column, a lifting assembly between the online acid mist exhaust gas monitor and the hollow column, the lifting assembly including a threaded rod disposed inside the hollow column, the top of the threaded rod being rotatably connected to the top of the inner side of the hollow column, the bottom of the threaded rod being rotatably connected to the bottom of the inner side of the base, a threaded sleeve being threadedly fitted on the top of the surface of the threaded rod, a connecting rod being disposed on one side of the threaded sleeve, and a sliding groove for the connecting rod to move on the surface of the hollow column near the online acid mist exhaust gas monitor, and a first gear being fixedly fitted on the bottom of the surface of the threaded rod, a second gear being meshed on one side of the first gear, a rotating rod being fixedly disposed on the bottom of the second gear, the bottom of the rotating rod being rotatably connected to the bottom surface of the inner side of the base, and a circular through hole being disposed on the top surface of the base, a rotating upright being disposed inside the circular through hole, the bottom of the rotating upright being fixedly connected to the top surface of the second gear.

[0005] Preferably, it also includes a protective component, which includes a protective cover that is slidably fitted onto the surface of the hollow column. A horizontal plate is provided on one side of the protective cover, and a column is provided at the bottom end of the horizontal plate. A threaded cylinder is slidably fitted onto the surface of the column, and a threaded column adapted to the threaded cylinder is also provided on one side of the top of the base.

[0006] Preferably, the circular through hole is located directly above the second gear.

[0007] Preferably, the thread helix angle of the threaded rod is less than the equivalent friction angle.

[0008] Preferably, the protective cover is made of plastic.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. By designing a base, hollow column, online acid mist exhaust gas monitor, and lifting component, the online acid mist exhaust gas monitor can be lowered by rotating the upright when it is damaged and needs to be repaired after it is installed in a designated position. This eliminates the need for personnel to climb with a ladder for maintenance, reducing the risk factor. The overall structure is compact and easy to operate, bringing convenience to the maintenance work of the staff.

[0010] 2. By designing a protective component, once the online acid mist exhaust gas monitor is raised to the designated position, personnel can pull the protective cover down along the surface of the hollow column, causing the protective cover to wrap around the rotating upright. Then, personnel can tighten the threaded cylinder onto the surface of the threaded column to fix the position of the protective cover, thereby effectively preventing the rotating upright from being touched by external forces, and thus ensuring good stability of the online acid mist exhaust gas monitor after it is installed in the designated position.

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] Please see Figure 1 , Figure 2This utility model provides a technical solution: an online pH monitoring device for acid mist exhaust gas, including a base 1, a hollow column 2 at the top of the base 1, an online acid mist exhaust gas monitor 3 installed on one side of the top of the hollow column 2, a lifting assembly between the online acid mist exhaust gas monitor 3 and the hollow column 2, the lifting assembly including a threaded rod 4 disposed inside the hollow column 2, the top of the threaded rod 4 being rotatably connected to the top of the inner side of the hollow column 2, the bottom of the threaded rod 4 being rotatably connected to the bottom of the inner side of the base 1, a threaded sleeve 5 being threadedly fitted onto the top of the surface of the threaded rod 4, a connecting rod 6 being disposed on one side of the threaded sleeve 5, and a groove 7 for the connecting rod 6 to move on the side of the hollow column 2 near the online acid mist exhaust gas monitor 3, and the threaded rod... A first gear 8 is fixedly sleeved on the bottom of the 4-surface base. A second gear 9 is meshed with one side of the first gear 8. A rotating rod 10 is fixedly installed at the bottom of the second gear 9. The bottom of the rotating rod 10 is rotatably connected to the bottom surface of the base 1. A circular through hole 11 is also provided on the top surface of the base 1. A rotating upright rod 12 is provided inside the circular through hole 11. The bottom of the rotating upright rod 12 is fixedly connected to the top surface of the second gear 9. The circular through hole 11 is directly above the second gear 9, so that the rotating upright rod 12 will not be obstructed during movement. The thread helix angle of the threaded rod 4 is less than the equivalent friction angle, ensuring that the threaded sleeve 5 will not move downward due to gravity, giving the threaded rod 4 a self-locking function. Online pH meters for acid mist exhaust gas monitoring are typically fixed to a column and cannot be flexibly raised or lowered. When the pH meter is damaged and needs repair, personnel must use a ladder to climb to a higher position, which is cumbersome and dangerous. To lower the pH meter, personnel simply need to hold the rotating rod 12 and rotate it in a circular motion. This rotation drives the second gear 9, which in turn drives the first gear 8, which in turn drives the threaded rod 4. During the rotation of the threaded rod 4, the threaded sleeve 5 descends slowly due to the mutual restraint between the connecting rod 6 and the sliding groove 7. When the set 5 descends, it also lowers the acid mist exhaust gas online monitoring instrument 3. Once the acid mist exhaust gas online monitoring instrument 3 has descended to a suitable height, personnel stop rotating the rotating pole 12. After that, personnel can then perform maintenance on the acid mist exhaust gas online monitoring instrument 3, completing the operation. By designing the base 1, hollow column 2, acid mist exhaust gas online monitoring instrument 3, and lifting components, after the acid mist exhaust gas online monitoring instrument 3 is installed in the designated position, when it is damaged and needs maintenance, personnel can simply rotate the rotating pole 12 to lower the acid mist exhaust gas online monitoring instrument 3. This eliminates the need for personnel to climb to a height for maintenance, reducing the risk factor. The overall structure is compact and easy to operate, bringing convenience to the maintenance work of the staff.

[0017] In this embodiment, preferably, please refer to... Figure 1 , Figure 2 , Figure 3As shown, it also includes a protective component, which includes a protective cover 13 that slides on the surface of the hollow column 2. A horizontal plate 14 is provided on one side of the protective cover 13, and a column 15 is provided at the bottom end of the horizontal plate 14. A threaded cylinder 16 is slidably fitted on the surface of the column 15, and a threaded column 17 that matches the threaded cylinder 16 is also provided on one side of the top of the base 1. The protective cover 13 is made of plastic, which effectively saves on material costs. By designing the protective component, when the acid mist exhaust gas online monitoring instrument 3 is raised to the designated position, the personnel can pull the protective cover 13 down along the surface of the hollow column 2 so that the protective cover 13 wraps around the rotating column 12. Then, the personnel can tighten the threaded cylinder 16 to the surface of the threaded column 17 to fix the position of the protective cover 13, thereby effectively preventing the rotating column 12 from being touched by external forces, and thus ensuring good stability of the acid mist exhaust gas online monitoring instrument 3 after it is installed in the designated position.
