Description

Technical Field

[0001] The utility model relates to a material level meter structure with self-cleaning function. Background Art

[0002] The material level meter is suitable for acid and alkali storage tanks, slurry storage tanks, solid particles, small oil storage tanks and other types of conductive, non-conductive media, corrosive media, such as coal bunkers, ash bunkers, oil tanks, acid tanks, etc., and has been widely used in various industries such as electricity, metallurgy, petrochemicals, papermaking, etc.

[0003] like Figure 1 As shown, when a level meter is used to measure the material level of a powder silo, fine powder particles (especially moist fine powder particles) will stick to the end of the level meter probe, making it impossible to accurately and real-time measure the material level. The level meter can only be removed for manual cleaning, which increases the workload.

[0004] The applicant owns a Chinese patent with patent number 202221213061.2, which provides an ultrasonic level meter device with a purge device, which can purge the condensed water at the end of the ultrasonic level meter sensor, which is conducive to the safe, stable and economical operation of the device. This patent solution is suitable for ultrasonic level meters in liquid environments, but for level meters in powder silo environments, the cleaning effect needs to be further improved. Utility Model Content

[0007] The utility model also comprises bolts and nuts, and the mounting flange is fixed on the counter flange through the bolts and nuts.

[0008] The installation flange of the utility model is provided with an installation hole, and the cleaning pipe is installed in the installation hole.

[0009] The outlet of the cleaning pipe of the utility model is located on the side of the end of the probe.

[0010] The utility model also comprises a ferrule joint, which is installed on the cleaning pipe and connected with the mounting flange to fix the cleaning pipe on the mounting flange.

[0011] The utility model also comprises a mounting pipe, the top of which is fixed on the mounting flange, the mounting pipe sleeve is arranged outside the probe of the material level meter, and the outlet of the cleaning pipe is mounted on the mounting pipe.

[0012] Compared with the prior art, the utility model has the following advantages and effects: when particles are attached to the end of the level meter probe, resulting in inaccurate measurement, the fine powder particles of the probe can be effectively cleaned to achieve accurate measurement of the level meter without removing the level meter, thereby reducing workload.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0017] The embodiment of the utility model comprises a sleeve 2, bolts and nuts 3, a counter flange 4, a mounting flange 5, a level meter 6, a ferrule joint 8, a three-way valve 9, a cleaning pipe 10, a mounting pipe 11, an air inlet pipe 12 and a water inlet pipe 13.

[0018] The casing 2 is embedded in advance or welded and fixed to the top of the silo 1 when constructing the silo 1. The counter flange 4 is welded and fixed to the top of the casing 2. The mounting flange 5 is fixed to the counter flange 4 by bolts and nuts 3. The level meter 6 is installed on the mounting flange 5, and the probe 7 of the level meter 6 extends into the casing 2. The above is a conventional installation structure of the level meter 6.

[0019] The mounting flange 5 is provided with a mounting hole, and the cleaning pipe 10 is mounted in the mounting hole, so that the cleaning pipe 10 is mounted on the mounting flange 5. The outlet of the cleaning pipe 10 is located in the sleeve 2 and faces the end of the probe 7. In this embodiment, the outlet of the cleaning pipe 10 is located on the side of the end of the probe 7, so that the cleaning effect is better; the inlet of the cleaning pipe 10 is located outside the sleeve 2.

[0020] The ferrule joint 8 is installed on the cleaning pipe 10 and connected to the mounting flange 5 to fix the cleaning pipe 10 on the mounting flange 5 .

[0021] The outlet of the three-way valve 9 is connected to the inlet of the cleaning pipe 10, one inlet of the three-way valve 9 is connected to the water inlet pipe 13, and the other inlet is connected to the air inlet pipe 12. The water inlet pipe 13 is used to take in cleaning water, and the air inlet pipe 12 is used to take in compressed air.

[0022] The top of the mounting pipe 11 is welded and fixed on the mounting flange 5, the mounting pipe 11 is sleeved on the outside of the probe 7 of the material level meter 6, and the outlet of the cleaning pipe 10 is installed on the mounting pipe 11 through the ferrule joint 8. The mounting pipe 11 not only fixes the outlet of the cleaning pipe 10, but also when cleaning, the compressed air and atomized water are flushed into the mounting pipe 11. The compressed air and atomized water are in a relatively small space and will not be dispersed too quickly, so the cleaning effect on the probe 7 is better.

[0023] The workflow of this utility model is as follows:

[0024] 1) When the material level meter 6 measures inaccurately, open the three-way valve 9 to let the compressed air in, but not the cleaning water. The compressed air enters the cleaning pipe 10 through the air inlet pipe 12, and then enters the inside of the installation pipe 11, and blows at the end of the probe 7. If the measurement is still inaccurate, proceed to the second step;

[0025] 2) Open the three-way valve 9 to allow compressed air and cleaning water to enter at the same time. The compressed air enters the cleaning pipe 10 through the air inlet pipe 12, and the cleaning water enters the cleaning pipe 10 through the water inlet pipe 13. The cleaning water is atomized by the compressed air and wrapped around the probe 7. The atomized water softens the dust adhering to the end of the probe 7. Then turn off the cleaning water and blow through the compressed air to blow away the particles attached to the probe 7 to achieve accurate measurement.

[0026] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. Any equivalent changes or simple changes made based on the structure, features and principles described in the concept of the utility model patent are included in the protection scope of the utility model patent.
