[0002] Pneumatic ash conveying, also known as air flow conveying, is a technology that uses the energy of air flow to convey granular materials along the air flow direction in a closed pipeline. Its basic principle is to use compressed air or other gases as the conveying medium to fluidize the material and then transport it through the pipeline.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1 , the present invention provides a technical solution:

[0017] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0018] Embodiment: The device collects the ash in the ash hopper 1, manually opens the dome valve 2, and all the ash falls into the silo pump 5, and then manually closes the dome valve 2, and the ash falls into the ash conveying pipe 7 through the silo pump 5, and the air compression pump at one end of the ash conveying pipe 7 is turned on to blow air, so that the air mixed with the ash moves along the ash conveying pipe 7. The connecting pipe 3 and the silo pump 5 are prone to dust accumulation. A pair of first temperature stickers 4 are located on the side wall surface of the connecting pipe 3, and a pair of second temperature stickers 6 are respectively located on the side wall surface of the silo pump 5. The temperature change in the connecting pipe 3 is sensed by a temperature sensor, and The temperature information transmitted by the pair of first temperature stickers 4 and the pair of second temperature stickers 6 is sent to the monitoring device 8 via a wireless signal, and the monitoring device 8 displays the temperature information transmitted by the pair of first temperature stickers 4 and the pair of second temperature stickers 6 via the display panel. The operator only needs to observe the temperature of the display panel to understand whether there is a blockage or ash adhesion problem. Because if blockage or ash adhesion occurs, the ash will accumulate and remain on the side wall of the connecting pipe 3 or the silo pump 5, and the temperature of the ash will continue to drop, driving the surface temperature of the connecting pipe 3 or the silo pump 5 to drop, so that the operator can understand the exact location of the blockage or ash adhesion, which is convenient for cleaning.
