[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown, an intelligent early warning device for sediment height in a silo of the present invention comprises a slag storage silo 1 and an inductive proximity sensor 3. An opening 2 is provided on the top of the slag storage silo 1 for connecting a slurry delivery pipe to input mud into the slag storage silo 1. After the mud is filtered by the filter screen, the sediment remains in the slag storage silo 1. The inductive proximity sensor 3 is installed on the top of the cylinder wall of the slag storage silo 1, and an inductive proximity sensor receiver 301 is installed on the top of the inductive proximity sensor 3, and a floating water cover 303 is connected to the bottom through a connecting rod 304. An inductive proximity sensor transmitter 302 is installed on the top of the floating water cover 303. When the sediment rises, the floating water cover 303 will be pressed up, causing it to rise, thereby driving the inductive proximity sensor transmitter 302 to rise. The change in the distance between the inductive proximity sensor receiver 301 and the transmitter 302 will be converted into an electrical signal, and the sediment height will be displayed in real time through the LCD display.

[0028] The outside of the slag storage bin 1 is connected to a liquid crystal display screen for digitally displaying the height of the slag in the bin from the bin top. The liquid crystal display screen is also connected to multiple inductive proximity sensors 3, and the monitoring height range can be adjusted by touch. In addition, a hidden handle is fixedly installed on the outside of the slag storage bin 1 to facilitate the rapid cleaning of the slag storage bin.

[0029] When in use, first move the monitoring device to the monitoring area and fix it. Then, fix the slurry delivery pipe at the slurry delivery hole 2 on the top of the slag storage bin 1. Issue instructions through the LCD screen, set the monitoring height, and clear the distance between the sensor transmitter 302 and the receiver 301. Next, operate the LCD screen to issue instructions to start detection, open the slurry delivery pipe to start slurry delivery. After the mud is filtered by the filter screen, the sediment continues to rise and accumulates on the floating water cover 303. The inductive proximity sensor transmitter 302 on the upper part of the floating water cover 303 transmits a signal, and the inductive proximity sensor receiver 301 on the upper part receives the signal. The LCD screen can view the monitoring process in real time. When the set monitoring height is reached, the LCD screen issues a "slag storage bin sediment is full warning" and the slag delivery pipe is automatically closed. After the monitoring is completed, the slag delivery pipe is removed, the slag storage bin 1 is opened to clean the sediment to an open space, and the slag storage bin door is closed. Finally, the LCD screen is connected to the mobile phone Bluetooth or a laptop computer, the monitoring data is exported, the sediment height is analyzed, and the final amount of sediment cleaned is calculated.

[0030] In summary, the present invention provides an intelligent silo sediment height warning device and monitoring method, which can monitor the silo sediment height in real time and accurately, improve the accuracy and reliability of monitoring, and provide strong support for related fields such as industrial production and foundation treatment.
