Description

Technical Field

[0001] This utility model relates to the field of rotary valve technology, and more specifically, to a rotary valve with anti-clogging monitoring function. Background Technology

[0002] In industrial production, rotary valves are widely used in many fields such as chemical, food, and building materials as key components of material conveying systems. Their main function is to continuously and stably transport materials from one space to another under different pressure environments, while maintaining the system's sealing to prevent gas leakage or material backflow.

[0003] A search revealed that Chinese patent CN219295734U discloses a rotary valve. This invention addresses the shortcomings of existing structures, such as the inability to precisely control the discharge speed of butterfly valves, the complexity of existing screw-type discharge structures, the need for extensive manual disassembly and cleaning, and the difficulty in cleaning. Existing rotary valves consist of two separate valve bodies connected by bolts, requiring the entire valve body to be disassembled for cleaning the valve core, resulting in significant time consumption for both disassembly and cleaning. This invention utilizes a rotary valve for weighing, batching, and powder dispensing, enabling automatic powder discharge with precise control of the discharge speed and quantity. Furthermore, this invention is easy to disassemble and clean, suitable for large-scale powder processing, and reduces the intensity of manual labor.

[0004] Materials often contain lumpy or fibrous impurities, or the materials themselves have sticky or easily agglomerated characteristics. These factors can easily cause materials to accumulate and block inside the rotary valve, hindering the normal rotation of the unloading rotor. If the rotary valve is blocked, the blockage cannot be detected in time, and effective cleaning and maintenance measures cannot be taken immediately, further aggravating the negative impact of the blockage on production. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a rotary valve with anti-clogging monitoring function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotary valve with anti-clogging monitoring function, comprising a rotary valve body, fixed tubes on both sides of the rotary valve body, a fixed column inside the fixed tube, a rotating shaft rotatably connected inside the fixed column, and a clogging monitoring mechanism inside the rotary valve body;

[0007] The blockage monitoring mechanism includes a discharge rotor, which is fixedly sleeved on the outside of the rotating shaft. A pressure sensor is fixedly installed inside the discharge rotor. Fixed annular plates are fixedly sleeved on the top and bottom outer sides of the rotary valve body. A first fixed plate is fixedly connected inside the fixed annular plate. An ultrasonic level sensor is fixedly installed at the bottom of the first fixed plate. A fixed platform is fixedly connected to the rear side of the rotary valve body. A microcontroller is fixedly installed on the front side of the fixed platform. An audible and visual alarm is fixedly connected to the top of the fixed platform.

[0008] Preferably, the microcontroller is electrically connected to the ultrasonic level sensor, pressure sensor, and audible and visual alarm.

[0009] Preferably, the top surface of the fixed annular plate is provided with mounting holes, and the number of mounting holes is set to multiple.

[0010] Preferably, a threaded groove is formed on one side surface of the fixing tube, and a second fixing plate is fixedly sleeved on the outside of the fixing column, with a threaded hole formed on one side surface of the second fixing plate.

[0011] Preferably, both the threaded groove and the threaded hole are internally threaded with fixing bolts.

[0012] Preferably, one end of the fixing column passes through the second fixing plate and extends into the interior of the fixing tube, and one end of the rotating shaft passes through the fixing column and extends into the interior of the fixing tube.

[0013] Preferably, the fixed pipe and the rotary valve body are fixedly connected by welding.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a blockage monitoring mechanism, the pressure sensor inside the unloading rotor monitors material pressure changes in real time, and the ultrasonic level sensor inside the fixed annular plate on the top and bottom of the rotary valve body detects material accumulation height changes. The blockage situation is accurately monitored from two dimensions: pressure and level. This dual monitoring mechanism can promptly detect abnormal accumulation of materials during the conveying process. Compared with a single monitoring method, it greatly improves the accuracy and timeliness of blockage monitoring, and buys valuable time for quick response measures. At the same time, the strong flashing light and high-decibel sound alarm emitted by the audible and visual alarm when a blockage occurs can quickly attract the attention of operators in a noisy working environment, promptly reminding them that the rotary valve is blocked, avoiding further deterioration of the blockage problem, and reducing production losses caused by blockage.

[0016] 2. Multiple mounting holes on the top surface of the fixed annular plate facilitate the installation of the rotary valve in a specific working position using bolts and other connecting parts, ensuring a stable installation and allowing for flexible adjustment of the installation position according to actual needs. At the same time, the connection between the fixed pipe and the fixed column through threaded grooves, threaded holes, and fixing bolts facilitates the installation and disassembly of the rotating shaft and the unloading rotor, greatly improving the convenience of equipment maintenance and repair, reducing maintenance time and costs, and improving the overall service life and operational reliability of the equipment.

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.

[0024] As attached Figure 1-5 The rotary valve shown includes a rotary valve body 1, fixed pipes 2 on both sides of the rotary valve body 1, fixed columns 3 inside the fixed pipes 2, a rotating shaft 4 rotatably connected inside the fixed columns 3, and a blockage monitoring mechanism inside the rotary valve body 1.

[0025] The blockage monitoring mechanism includes a discharge rotor 5, which is fixedly sleeved on the outside of the rotating shaft 4. A pressure sensor 17 is fixedly installed inside the discharge rotor 5. Fixed annular plates 6 are fixedly sleeved on the top and bottom outer sides of the rotary valve body 1. A first fixed plate 7 is fixedly connected inside the fixed annular plate 6. An ultrasonic level sensor 8 is fixedly installed at the bottom of the first fixed plate 7. A fixed platform 9 is fixedly connected to the rear side of the rotary valve body 1. A microcontroller 10 is fixedly installed on the front side of the fixed platform 9. An audible and visual alarm 11 is fixedly connected to the top of the fixed platform 9.

[0026] As attached Figure 2 , 3 As shown, the microcontroller 10 is electrically connected to the ultrasonic level sensor 8, the pressure sensor 17, and the audible and visual alarm 11, which facilitates signal transmission to the microcontroller 10, thereby enabling the audible and visual alarm 11 to issue a blockage alarm.

[0027] As attached Figure 1 , 2 As shown in Figure 4, the top surface of the fixed annular plate 6 is provided with mounting holes 12, and the number of mounting holes 12 is set to be multiple, which facilitates the installation of the rotary valve body 1.

[0028] As attached Figure 1-5 As shown, a threaded groove 14 is provided on one side surface of the fixed tube 2, and a second fixed plate 13 is fixedly sleeved on the outside of the fixed column 3. A threaded hole 15 is provided on one side surface of the second fixed plate 13. Fixed bolts 16 are threadedly connected inside the threaded groove 14 and the threaded hole 15. One end of the fixed column 3 passes through the second fixed plate 13 and extends into the fixed tube 2. One end of the rotating shaft 4 passes through the fixed column 3 and extends into the fixed tube 2, which facilitates the disassembly and replacement of the rotating shaft 4 and the unloading rotor 5.

[0029] As attached Figure 1-4 As shown, the fixed pipe 2 and the rotary valve body 1 are fixedly connected by welding, which improves the overall sealing effect of the rotary valve.

[0030] The working principle of this utility model is as follows: The unloading rotor 5 is fixedly sleeved on the outside of the rotating shaft 4. When the material enters the rotary valve body 1, it pushes the unloading rotor 5 to rotate around the rotating shaft 4, thereby realizing the material conveying. A pressure sensor 17 is fixedly installed inside the unloading rotor 5. When the material is conveyed normally, the pressure sensor 17 will monitor a relatively stable pressure value. Once a blockage occurs, the material accumulates inside the unloading rotor 5, causing a pressure change. The pressure sensor 17 can sense this pressure change in real time and transmit the pressure data to the microcontroller 10. Fixed annular plates 6 are fixedly sleeved on the top and bottom outer sides of the rotary valve body 1. An ultrasonic level sensor 8 is fixedly installed inside the fixed annular plate 6 through a first fixed plate 7. The ultrasonic level sensor 8 emits ultrasonic waves into the rotary valve body 1 and detects the reflected waves. The ultrasonic level sensor 8 calculates the material level height by measuring the time of wave motion. When blockage occurs, the material accumulation height changes. The ultrasonic level sensor 8 transmits the detected level data change to the microcontroller 10. The microcontroller 10 is electrically connected to the ultrasonic level sensor 8, the pressure sensor 17, and the audible and visual alarm 11. After receiving data from the pressure sensor 17 and the ultrasonic level sensor 8, the microcontroller 10 analyzes and processes the data according to a preset algorithm. When the pressure data or level data exceeds the normal range, the microcontroller 10 determines that the rotary valve is blocked. Once the microcontroller 10 determines that a blockage has occurred, it immediately triggers the audible and visual alarm 11, which is electrically connected to it. The audible and visual alarm 11 emits a strong flashing light and a sound alarm to remind the operator that the rotary valve is blocked so that timely cleaning and other maintenance measures can be taken.
