Description

Technical Field

[0001] This utility model relates to the field of online analytical instrument technology, specifically a filter structure for the interface of an online analytical instrument. Background Technology

[0002] Online analytical instruments are automated analytical instruments specifically designed for use in chemical production processes. They are also known as process analytical instruments or quality monitoring instruments and are widely used for real-time analysis in industrial production and continuous monitoring of environmental quality and pollution emissions.

[0003] The filter structure used in the interface of online analytical instruments is a key component that ensures the removal of mechanical impurities, dust, suspended matter, and chemical components from samples that may interfere with analysis or corrode system components, thereby protecting the normal operation of the instrument and providing accurate measurement results.

[0004] In existing technologies, replacing the filter unit in an online analytical instrument interface requires shutting off the flow in the pipeline via a valve. However, after the valve is closed, the flow in the pipeline stagnates for an extended period, causing the online analytical instrument to experience stagnation or gaps in its measurements, resulting in inaccurate results. Therefore, those skilled in the art have provided a filter structure for online analytical instrument interfaces to address the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filter structure for the interface of online analytical instruments. This solves the problem that in existing technologies, when replacing the filter unit in the interface of online analytical instruments, it is necessary to cut off the flow in the pipeline through a valve. However, after the valve is closed, the flow in the pipeline stagnates for a long time, causing the data measured by the online analytical instrument to stagnate or become discontinuous, resulting in inaccurate measurement results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter structure for an online analytical instrument interface, comprising an interface pipe, a break in the middle of the interface pipe, a reinforcing block installed on one side of the interface pipe, a stepper motor installed inside the reinforcing block, a gear driven by the upper output end of the stepper motor, an online analytical instrument body installed at the lower end of the reinforcing block, a fixed shaft installed on the side of the interface pipe away from the reinforcing block, a turntable installed on the fixed shaft, a threaded hole on the turntable, a filter plate threadedly connected to the threaded hole, and toothed grooves on the peripheral sidewall of the turntable.

[0007] Preferably, the online analytical instrument body passes through the reinforcing block and is connected to the lower part of the interface pipe.

[0008] Preferably, the turntable has a through hole in the middle, and the turntable is rotatably connected to the fixed shaft through the through hole.

[0009] Preferably, the tooth groove engages with the gear, and the gear is driven to rotate by a stepper motor. The rotation of the gear drives the turntable to rotate, so that the clean filter plate on the turntable moves into the break in the interface pipe, thereby realizing the rapid replacement of the filter plate.

[0010] Preferably, annular grooves are formed in the two end faces of the fracture, and a pressure ring is provided in the annular groove.

[0011] Preferably, a spring is installed at the end of the pressure ring away from the break, and a sealing ring is installed at the end of the pressure ring adjacent to the break. The sealing ring is in contact with the turntable by compression. The contact between the sealing ring and the turntable can improve the sealing between the turntable and the interface pipe. Moreover, the diameter of the sealing ring is larger than the inner diameter of the threaded hole, so there will be no problem of it entering the threaded hole.

[0012] Compared with the prior art, this utility model provides a filter structure for the interface of an online analytical instrument, which has the following advantages:

[0013] Through design, the filter structure for the online analytical instrument interface in this utility model includes an interface pipe, the online analytical instrument body, a turntable, and filter plates. A break is made in the middle of the interface pipe. When the filter plate in the turntable becomes clogged, causing a reduction in flow, a stepper motor drives a gear to rotate. The rotation of the gear drives the turntable to rotate, moving the clean filter plate on the turntable to the break in the interface pipe, thereby achieving rapid replacement of the filter plate. This replacement method does not require switching valves to cut off the flow in the interface pipe, reducing the replacement time of the filter unit and thus reducing the problems of data acquisition stagnation and interruption in the online analytical instrument body.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] This utility model provides a technical solution: a filter structure for an interface of an online analytical instrument. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 The system includes an interface pipe 1, with a break 101 in the middle of the interface pipe 1. A reinforcing block 2 is installed on one side of the interface pipe 1, and a stepper motor 10 is installed inside the reinforcing block 2. A gear 11 is driven and connected to the upper output end of the stepper motor 10. An online analysis instrument body 3 is provided at the lower end of the reinforcing block 2. The online analysis instrument body 3 passes through the reinforcing block 2 and is connected to the lower part of the interface pipe 1. A fixed shaft 8 is installed on the side of the interface pipe 1 away from the reinforcing block 2. A turntable 4 is provided on the fixed shaft 8. A threaded hole 401 is provided on the turntable 4. A filter plate 9 is threadedly connected inside the threaded hole 401. A toothed groove 402 is provided on the peripheral side wall of the turntable 4.

[0020] Please see Figure 1 , Figure 2 , Figure 3 The turntable 4 has a through hole 403 in the middle. The turntable 4 is rotatably connected to the fixed shaft 8 through the through hole 403. The tooth groove 402 is in contact with the gear 11. The stepper motor 10 drives the gear 11 to rotate. The rotation of the gear 11 drives the turntable 4 to rotate, so that the clean filter plate 9 on the turntable 4 moves into the break 101 of the interface pipe 1, thereby realizing the quick replacement of the filter plate 9. The two end faces of the break 101 have annular grooves 102. The annular grooves 102 are provided in the annular grooves 102. The pressure ring 5 is provided in the annular grooves 102. The end of the pressure ring 5 away from the break 101 is equipped with a spring 6. The end of the pressure ring 5 adjacent to the break 101 is equipped with a sealing ring 7. The sealing ring 7 is in contact with the turntable 4. The contact between the sealing ring 7 and the turntable can improve the sealing between the turntable 4 and the interface pipe 1. Moreover, the diameter of the sealing ring 7 is larger than the inner diameter of the threaded hole 401, so there will be no problem of entering the threaded hole 401.

[0021] The filter structure for the interface of the online analytical instrument in this utility model includes an interface pipe 1, an online analytical instrument body 3, a turntable 4, and a filter plate 9. A break 101 is provided in the middle of the interface pipe 1. Annular grooves 102 are provided in the upper and lower end faces of the break 101. A pressure ring 5 is provided in the annular groove 102. A spring 6 is installed at the end of the pressure ring 5 away from the break 101, and a sealing ring 7 is installed at the end of the pressure ring 5 adjacent to the break 101. A reinforcing block 2 is installed on one side of the interface pipe 1 to improve the stability of the interface pipe 1. A stepper motor 10 is provided in the reinforcing block 2. A gear 11 is driven and connected to the upper output end of the stepper motor 10. The gear 11 is located on one side of the break 101. The online analytical instrument is connected to the lower part of the interface pipe 1 after passing through the lower end of the reinforcing block 2.

[0022] A fixed shaft 8 is installed on the side of the interface pipe 1 away from the reinforcing block 2. The fixed shaft 8 also serves to stabilize the interface pipe 1. A turntable 4 is rotatably sleeved on the height shaft. Several threaded holes 401 are opened on the turntable 4. A filter plate 9 is threaded inside the threaded holes 401. The filter plate 9 can be replaced. Gear grooves 402 are opened on the peripheral side wall of the turntable 4. The gear grooves 402 mesh with the gear 11. The sealing ring 7 is pressed against the turntable 4. The diameter of the sealing ring 7 is larger than the inner diameter of the threaded hole 401, so there will be no problem of entering the threaded hole 401.

[0023] When the filter plate 9 in the break 101 of the turntable 4 becomes clogged, causing a reduction in flow, the stepper motor 10 drives the gear 11 to rotate. The rotation of the gear 11 drives the turntable 4 to rotate, so that the clean filter plate 9 on the turntable 4 moves into the break 101 of the interface pipe 1, thereby realizing the rapid replacement of the filter plate 9. This replacement method does not require switching valves to cut off the flow in the interface pipe 1, reducing the replacement time of the filter unit, and thus reducing the problem of data acquisition stagnation and interruption in the online analysis instrument body 3.
