Technical Field

[0001] The utility model relates to the technical field of silo monitoring equipment, in particular to a petroleum coke storage silo pendulum type material level monitoring device with a limit switch. Background Art

[0002] Petroleum coke silos are facilities specifically used to store petroleum coke. They are usually cylindrical or rectangular enclosed structures made of steel or concrete.

[0003] The pendulum-type material level monitoring device is an instrument used to measure the height of materials in a silo. When there is no material in the silo, the pendulum is in a natural drooping state. As the material gradually accumulates, the material will contact the pendulum and exert force on it, causing the pendulum to deviate from the natural drooping position, thereby driving the trigger sensor, and the sound and light alarm light corresponding to the storage silo number will sound, reminding that the silo is full. The application effect is good.

[0004] In the existing technology, the pendulum-type material level monitoring equipment has a relatively simple structure, reasonable design, and is easy to use. It can well indicate the material level status of the storage bin. However, there is a shortcoming that most of them add sensors to the pendulum to determine the material level changes through the sensors. Due to the large amount of dust in the bin, after long-term use, the sensor is covered with dust, which can easily cause the material level to be unable to be correctly sensed, thereby affecting normal production. Therefore, a petroleum coke storage bin pendulum-type material level monitoring equipment with a limit switch is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a petroleum coke storage bin pendulum type material level monitoring device with a limit switch, aiming to improve the problem in the existing technology that the sensor is easily covered by dust and the sensing is not timely, which leads to the inability to correctly indicate the material level.

The petroleum coke falls into the storage bin 2 through the discharge pipe 3. When the material level reaches the position of the baffle 7, the petroleum coke will generate a thrust on the side of the baffle 7. The baffle 7 drives the connecting rod 6 to swing, and the connecting rod 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives one end of the connecting block 15 to move downward, thereby driving the gasket 16 to move downward, pulling the spring 2 19 and making the gasket 16 vertically contact the limiter 17, so that the limit switch is triggered, thereby driving the sound and light alarm 21 to start. When the material level is normal, the reaction force of the spring 2 19 drives the connecting block 15 to reset, and the gasket 16 moves away from the limiter 17, thereby turning off the sound and light alarm 21, realizing that the equipment drives the limiter 17 quickly and stably through the pendulum, thereby timely and effectively reflecting the material level situation, is less affected by dust, and greatly improves the practicality of the equipment.

[0033] Reference Figure 2-Figure 4 The fixing assembly includes a slide groove 9, which is opened on one side of the mounting seat 8.

The baffle 7 drives the connecting rod 6 to swing, and the connecting rod 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives one end of the connecting block 15 to move downward, and then drives the gasket 16 to move downward, pulling the spring 2 19 and making the gasket 16 vertically contact the limiter 17, so that the limit switch is triggered, and then drives the sound and light alarm 21 to start. When the material level is normal, the reaction force of the spring 2 19 drives the connecting block 15 to reset, and the gasket 16 moves away from the limiter 17, and then turns off the sound and light alarm 21, realizing that the equipment can quickly and stably drive the limiter 17 through the pendulum, thereby timely and effectively reflecting the material level situation, and is less affected by dust, greatly improving the practicality of the equipment.

[0036] Secondly, the rotating cover 11 is aligned with the mounting seat 8 and inserted vertically, so that the pressure block 13 squeezes the spring 10, and the protrusion 12 is vertically inserted into the entrance end of the slide groove 9. The rotating cover 11 is rotated so that the protrusion 12 slides on the surface of the slide groove 9 and finally enters the deepest part of the slide groove 9.
