[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] according to Figure 1-4This utility model provides a quick cleaning mechanism for a radar level gauge waveguide connector, comprising: a cleaning tube 1 and a connecting cylinder 2.

[0022] Connecting cylinder 2 is connected to the reactor. A waveguide connector extends into connecting cylinder 2. Two cleaning tubes are positioned opposite each other on both sides of connecting cylinder 2 and extend into connecting cylinder 2. Two cleaning tubes 1 are positioned opposite each other on both sides of the reactor and extend into connecting cylinder 2. Cleaning tube 1 includes: an inlet pipe 11 and a jet pipe 12. The inlet pipe 11 is connected to the jet pipe 12. The jet pipe 12 faces the waveguide connector.

[0023] By incorporating the connecting tube 2, less liquid splashes onto the waveguide connector, making subsequent processing easier. When cleaning the waveguide connector is required, airflow enters through the inlet pipe 11 and exits through the jet pipe 12. Since the jet pipe 12 faces the waveguide connector, impurities on the connector are blown off, preventing obstruction of its outer surface. By using two cleaning pipes 1 on both sides to clean the waveguide connector, all parts of the connector can be cleaned. Nitrogen gas can be introduced into the inlet pipe 11 to remove most impurities without reacting with the material. Airflow can also be introduced periodically for cleaning.

[0024] The cleaning pipe 1 also includes: a circular plate 13, a return spring 14, and a retaining ring 15. The return spring 14 is disposed inside the intake pipe 11. One end of the return spring 14 near the jet pipe 12 is fixed to the intake pipe 11, while the other end is movable relative to the intake pipe 11. The circular plate 13 is connected to the end of the return spring 14 away from the jet pipe 12. The retaining ring 15 is disposed on the side of the circular plate 13 away from the return spring 14. The outer edge of the retaining ring 15 is in contact with the inner wall of the intake pipe 11. The diameter of the circular plate 13 is larger than the inner diameter of the retaining ring 15; the diameter of the circular plate 13 is smaller than the inner diameter of the intake pipe 11. The intake pipe 11 slopes downwards from the side away from the jet pipe 12 to the other side.

[0025] The return spring 14, located away from the jet pipe 12 within the inlet pipe 11, is movable relative to the inlet pipe 11 and connected to the circular plate 13, allowing the circular plate 13 to move relative to the inlet pipe 11. The outer edge of the retaining ring 15 is fitted against the inner wall of the inlet pipe 11, ensuring that airflow can only flow within the inner ring of the retaining ring 15. The circular plate 13, with a diameter larger than the inner diameter of the retaining ring 15, can block the retaining ring 15, preventing airflow. When airflow enters the inlet pipe 11, the retaining ring 15 applies pressure to the circular plate 13, compressing the return spring 14 and causing the circular plate 13 to move away from the retaining ring 15, allowing airflow to pass through and clean the waveguide connector via the jet pipe 12. When no airflow enters, the return spring 14 springs back, blocking the retaining ring 15, preventing liquid and gas from passing through even when the cleaning pipe 1 is closed, ensuring the sealing of the reactor and preventing liquid leakage. By tilting the air intake pipe 11 downwards from one side away from the jet pipe 12 to the other side, the circular plate 13 will move closer to the fixed ring 15 due to gravity, making the circular plate 13 fit more tightly with the fixed ring 15, thus improving the sealing effect of the cleaning pipe 1.

[0026] The cleaning pipe 1 also includes: a baffle 16, a telescopic spring 17, and a fixing rod 18. The jet pipe 12 has a jet port 121 on the side away from the air intake pipe 11. The fixing rod 18 is located on the side of the jet port 121 near the air intake pipe 11. The baffle 16 is located on the side of the fixing rod 18 near the jet port 121. A telescopic rod 161 is provided on the side of the baffle 16 near the fixing rod 18. The fixing rod 18 has a telescopic opening 181. The telescopic rod 161 can extend and retract through the telescopic opening 181. The baffle 16 is larger than the jet port 121. The cleaning pipe 1 also includes: a telescopic spring 17. The baffle 16 also includes: a sealing plate 162 and a fixing plate 163. The sealing plate 162 is in contact with the fixing plate 163. The sealing plate 162 can move relative to the fixing plate 163. The sealing plate 162 is smaller than the jet port 121. The sealing plate 162 can extend into the jet port 121. One end of the telescopic rod 161 is connected to the enclosed plate 162, and the other end can extend and retract through the telescopic opening 181. One end of the telescopic spring 17 is connected to the enclosed plate 162, and the other end is connected to the fixed rod 18. The circular plate 13 is provided with an abutment rod 131 on the side near the fixed rod 18. The abutment rod 131 and the telescopic rod 161 are on the same straight line.

[0027] A baffle 16 is installed inside the jet pipe 12 to block the jet nozzle 121, ensuring that liquid splashing in can only enter the jet pipe 12, which is inclined downwards towards the connecting cylinder 2, thus preventing certain materials from affecting the return spring 14 and other structures. When airflow is introduced, the airflow pushes the circular plate 13 to move, causing the contact rod 131 to move towards the telescopic rod 161, which is then contacted. This causes the telescopic rod 161 to move towards the jet nozzle 121 within the telescopic port 181, separating the sealing plate 162 from the fixed plate 163 and stretching the telescopic spring 17. The jet nozzle 121 then connects to the air inlet pipe 11, allowing airflow to pass through. When the airflow stops, the telescopic spring 17 rebounds, blocking the jet nozzle 121. This allows for automatic control of the opening and closing of the jet nozzle 121, facilitating its use.

[0028] Working principle and usage process of this utility model:

[0029] When cleaning the waveguide connector is required, airflow is introduced into the air inlet pipe 11, causing the airflow to move towards the circular plate 13. This applies pressure to the circular plate 13, moving it away from the retaining ring 15, and compressing the return spring 14. Simultaneously, the contact rod 131 moves towards the telescopic rod 161, causing the telescopic rod 161 to be contacted. The telescopic rod 161 then moves towards the jet nozzle 121 within the telescopic port 181, separating the sealing plate 162 from the retaining plate 163. The telescopic spring 17 is then stretched, and the airflow, after passing through the retaining ring 15, moves towards the jet pipe 12 and is ejected from the jet nozzle 121 onto the waveguide connector, cleaning impurities from the connector. After the airflow is stopped, the telescopic spring 17 returns, causing the sealing plate 162 to re-adhere to the retaining plate 163, and the return spring 14 also returns to its original position, adhering to the retaining ring 15, thus sealing the cleaning pipe 1.

[0030] In summary, this utility model, by setting a connecting cylinder that is connected to the reaction vessel and providing cleaning pipes on both sides of the connecting cylinder, allows airflow to be introduced through the cleaning pipes to clean the waveguide connector inside the connecting cylinder, thus ensuring the accuracy of waveguide connector monitoring.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
