Remote control system for intelligently monitoring material deposition in pipeline in pneumatic conveying

Abstract

The invention discloses a remote control system for intelligently monitoring material deposition in a pipeline in pneumatic conveying, which comprises a main controller, a wireless communication module, a cloud server, a deposition detection terminal and a mobile phone client, wherein the deposition detection terminal is laid on the lower pipe wall of the bottom of a double-sleeve pipe and is connected with the main controller; the main controller communicates with the cloud server through the wireless communication module; the deposition detection terminal comprises a capacitive antenna, an insulating sheet and a measuring unit; the ratio S11 of incident power to reflected power of a signal source output by the capacitive antenna is positively correlated with the thickness of a depositionlayer in a pipe, the insulating sheet is tightly attached to the bottom of the pipe, the capacitive antenna is fixed to the insulating sheet, the grounding end of the capacitive antenna is directly fixed to the bottom of the pipe, and the bottom of the pipe is grounded; the feed end of the capacitive antenna is led out of the pipe wall through a wire to be connected with a chip pin in the measuring unit, and the measuring unit is connected with the main controller through an SPI interface. The system can detect the deposition amount of the double-sleeves pipe in unit area in real time.

Description

technical field [0001] The invention relates to the technical field of pneumatic conveying, in particular to a remote control system for intelligently monitoring material deposition in pipelines during pneumatic conveying. Background technique [0002] Pneumatic conveying has been widely used in industrial fields such as electric power, food, mining, metallurgy, chemical industry and pharmaceuticals, especially in thermal power plants, when using double casings to convey granular materials, it can achieve large output of materials and long-distance transportation . However, it is impossible to monitor the material deposition in the pipeline in real time during the transportation process. When the material deposition is too serious, it cannot be dealt with in time. In severe cases, the system will be completely paralyzed and the safety of the equipment will be endangered. In order to ensure the safe operation of conveying facilities, convenient and effective material deposit...

Problems solved by technology

[0003] At present, there are few structures on the market that monitor material deposition in pipelines in pneumatic conveying. Most of the detection of material deposition is manual detection, and there are also long-distance wireless detections. For example, a Chinese patent (patent No. A remote monitoring system and detection method for the amount of fine dust deposition. Based on the photoelectric effect, a Fresnel lens is installed at the bottom of the dust collection tank, and the weight of the dust accumulation is converted into dust according to the influence of the accumulation of dust on the change of light intensity, and transmitted to the Cloud computing center, wireless and automatic monitoring of multiple monitoring points

However, its deposition detection terminal is too complicated and takes up a lot of space. If the deposition thickness is too large, light cannot pass through, and the measurement data error will increase. Based on the photoelectric effect, only a small amount of deposition can be monitored, which cannot be applied to large-scale, long-distance transportation. double casing structure
