[0012] Beneficial Effects

[0013] The present invention provides a pipe blockage monitoring system for a pneumatic ash conveying system. The present invention designs a structure that can conveniently and quickly locate the ash conveying blockage position. The device concentrates the ash body in the ash hopper, and the ash body falls into the ash conveying pipeline through the bin pump. The air compression pump is turned on to make the air mixed with the ash body move along the ash conveying pipeline. Several temperature stickers will sense the temperature of the ash conveying pipeline at the location through the temperature sensor, and transmit it to the monitoring device through wireless signals.

[0019] The present embodiment is further configured such that the dome valve 2 can be adjusted manually.

[0020] This embodiment is further configured such that ash bodies can be stored in the silo pump 3 .

[0021] The present embodiment is further configured such that the silo pump 3 is in a shape of being wide at the top and narrow at the bottom.

[0022] This embodiment is further configured such that a plurality of the temperature stickers 5 are installed on the side wall surfaces of the ash conveying pipeline 4 in different directions, and the distance between any two of the temperature stickers 5 is the same.

[0023] 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.

[0024] Embodiment: The device concentrates the ash body in the ash hopper 1, manually opens the dome valve 2, and all the ash body falls into the silo pump 3, and then manually closes the dome valve 2. The ash body passes through the silo pump 3 and falls into the ash conveying pipe 4. The air compression pump at one end of the ash conveying pipe 4 is turned on to blow air so that the air mixed with the ash body moves along the ash conveying pipe 4. Since the temperature of the ash body generally reaches about 200 degrees, the heat will be transferred when passing through the ash conveying pipe 4, so that the temperature of the ash conveying pipe 4 rises to about 90 degrees, and several temperature stickers 5 will sense the temperature of the ash conveying pipe 4 at the location through the temperature sensor, and transmit it to the monitoring device 6 through the wireless signal. The operator can observe the sensed temperature of several temperature stickers 5 through the display panel connected to the monitoring device 6. If blockage occurs or the ash body adheres to the inner wall of the ash conveying pipe 4, the ash body temperature at this location will cool down after a period of time, so that the surface temperature at its location will drop, so that the operator can understand the exact location where the blockage or ash body adheres, which is convenient for cleaning.
