Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below.
Referring to fig. 1 to 7, an automatic ash removal device 200 for a blower inlet box includes an ash removal pipeline 210 for removing ash from the bottom of the blower inlet box 10, and a return pipeline 220 connected to the ash removal pipeline 210. The two sets of ash removal devices 200 in this embodiment are symmetrically disposed at the left and right ends of the blower, respectively.
The ash cleaning pipeline 210 comprises at least one air inlet box ash cleaning pipe 211 arranged in the air inlet box 10 of the fan, one end of the return pipeline 220 is communicated with the inner cavity of the volute 20, the other end of the return pipeline is connected with the ash cleaning pipeline 210, and the return pipeline 220 is provided with a control valve assembly 230 connected with an external control device 300. The control device 300 may be a central control system commonly used in the industry at present, which is a conventional technology.
The air inlet box dust removing pipe 211 in this embodiment is arranged in parallel along the axial direction of the fan, one end of the air inlet box dust removing pipe 211 extends into the inner cavity of the air inlet box 10, the other end of the air inlet box dust removing pipe 211 is left outside the air inlet box 10 and is connected with the other end of the return pipeline 220, and a plurality of nozzles 212 are arranged at the bottom of the air inlet box dust removing pipe 211 at intervals along the axial direction. Specifically, the lower part of the air inlet box ash removal pipe 211 is provided with a plurality of nozzles 212 on the same radial cross section at intervals in the circumferential direction, and a central angle a formed between each two adjacent nozzles and the central axis of the air inlet box ash removal pipe is 45 degrees, so that the left and right coverage of the nozzles is realized, and the bottom of the air inlet box 10 is ensured not to have ash removal dead angles.
The return line 220 includes a return line 221 and an intermediate line 222, one end of the return line 221 is communicated with the inner cavity of the volute 20, the other end is connected with the intermediate line 222, the intermediate line 222 is connected with the ash removal line 210, and the control valve assembly 230 is disposed on the return line 221. The middle pipe 222 is a local arc pipe structure concentrically arranged with the main shaft 40 of the blower, three connecting holes 222a are arranged on the middle pipe 222 at intervals along the length direction, and each connecting hole 222a is connected with an air inlet box dust removing pipe 211.
