The embodiment of the application provides an ash conveying device, as shown in fig. 1 and fig. 2, the ash conveying device comprises an ash conveying pipeline 1, a three-way pipe 2 and a first air inlet pipeline 3, a first port 21 of the three-way pipe 2 is communicated with the ash conveying pipeline 1, and the ash conveying pipeline 1 is used for receiving smoke dust particles conveyed by an ash bin; the second port 22 of the three-way pipe 2 is used for conveying the smoke dust particles from the ash conveying pipeline 1 to the suction pressure conveying vehicle; the third port 23 of tee 2 is blind. The first air inlet pipeline 3 is communicated with the external air, and the first air inlet pipeline 3 is provided with a control device for controlling the unidirectional circulation of the air into the three-way pipe 2; a first air inlet communicated with the first air inlet pipeline 3 is arranged on the pipe body of the three-way pipe 2.
In particular, as shown in fig. 4-6, tee 2 comprises a first port 21, a second port 22 and a third port 23, the first port 21 being connected to the terminal 13, the second port 22 being for ash discharge, the third port 23 being blind, which third port 23 is in this embodiment blocked by a baffle 24. The air inlet pipeline 3 is arranged on the pipe body of the three-way pipe 2, the first air inlet pipeline 3 comprises a first end 31 and a second end 32, the first end 31 is communicated with the atmosphere, and the second end 32 is communicated with the three-way pipe 2.
In this embodiment, the second port 22 may be directly used as the ash outlet 11 or the second port 22 is connected to a section of a pipeline, the second port 22 discharges ash through the pipeline, and the ash outlet 11 is located on the pipeline, which is not limited in this application. The end of the ash conveying pipeline 1 far away from the ash outlet 11 is defined as a head end 12, the end close to the ash outlet is defined as a tail end 13, the head end 12 is used for receiving the smoke and dust particles conveyed by the ash bin, the tail end 13 is connected with a second port 22 of the three-way pipe 2, and the second port 22 is used for conveying the smoke and dust particles from the ash conveying pipeline 1 to the suction pressure conveying vehicle. The suction pressure conveying trolley forms a vacuum environment under the driving of the vacuum pump, and negative pressure is formed between the suction pressure conveying trolley and the ash outlet 11, so that smoke particles are transferred to the suction pressure conveying trolley by means of negative pressure adsorption. Set up first inlet duct 3 between first port 21 and second port 22, first inlet duct 3 can communicate with the atmosphere to promote the fluidized state of material, ensure that the smoke and dust granule in the ash conveying pipeline 1 is discharged by ash hole 11 smoothly, reduce the risk that the smoke and dust granule deposits here, thereby reduce the risk of tee bend pipe 2 department jam. The control device of one-way circulation can control the flow direction of gas in the first air inlet pipe 3 for the first air inlet pipe 3 only allows outside air to enter the three-way pipe 2 through the control device of one-way circulation, and does not allow smoke and dust particles in the three-way pipe 2 to enter the air through the control device of one-way circulation.

In addition, the three-way pipe 2 arranged at the tail end 13 of the ash conveying pipeline 1 can further increase the flow area of the ash outlet 11 and improve the problem that dead angles are easy to occur in direct elbow connection compared with the mode that the ash conveying pipeline 1 is directly connected with a section of elbow, so that the risk of blockage at the position is further reduced.
It should be noted that the pipe diameter of the ash conveying pipeline 1 needs to be matched with the rated volume of the tank body of the suction pressure conveying vehicle. According to the rated volume of the tank body of the suction delivery vehicle, the calculated pipe diameter matched with the economic flow rate is not too low in flow rate in the pipeline due to too large pipe diameter, and is not too large in abrasion to the pipeline, pipe fittings and the like due to too small pipe diameter and high flow rate. For example, when the tank body of the suction-pressure feed vehicle has a rated volume of 23m 3 The ash conveying pipe 1 can adopt the specification of pipe diameter D159 multiplied by 4.5, wherein D159 is the diameter of the ash conveying pipe 1, and 4.5 is the wall thickness of the ash conveying pipe 1.

In this embodiment, the extension line of the second end 32 forms a predetermined angle θ with the ash conveying pipe 1, and the predetermined angle θ means that a certain angle between the air inlet direction of the first air inlet pipe 3 to the three-way pipe 2 and the ash outlet direction of the ash conveying pipe 1 is a predetermined angle θ. When the preset included angle theta is larger than 0 degrees and smaller than 90 degrees, the smoke dust particles are favorably dispersed, the fluidization state of materials can be promoted, and the risk of blockage of the three-way pipe 2 is reduced.
Further, the preset included angle θ may be greater than 30 ° and smaller than 60 ° to better disperse the soot particles and reduce the risk of blockage of the tee 2, as shown in fig. 4, the preset included angle θ is 45 °.
In one embodiment, shown in fig. 1 and 2, the one-way flow control means is a check valve 4, and the check valve 4 is capable of controlling the flow direction of the gas in the first gas inlet pipe 3, so that the first gas inlet pipe 3 only allows the outside air to enter the tee pipe 2 through the check valve 4, and does not allow the smoke particles in the tee pipe 2 to enter the air through the check valve 4. Therefore, the control device with one-way circulation is set as the check valve 4, and the structure is simple.
In an embodiment the first inlet conduit 3 is further provided with a shut-off valve 5, and a non-return valve 4 is arranged between said shut-off valve 5 and the third port 23.

One end of the insert 6 is fixed to the baffle 24, and the two may be fixed by welding. An extension of the second end 32 of the first air inlet duct 3 intersects the insert 6 so that the insert 6 can block the gas blown out of the first air inlet duct 3, thereby changing the direction of the gas blown out of the first air inlet duct 3. The direction of the air blown out from the first air inlet pipeline 3 after being blocked by the plug-in piece 6 becomes more dispersed, so that the deposition of smoke particles can be avoided, the fluidization state of materials is promoted, and the risk of blockage in the three-way pipe 2 is reduced.
Specifically, the insert 6 is cylindrical, that is, the outer surface of the insert 6 along the length direction is circular, and the length direction of the insert 6 is consistent with the length direction of the ash conveying pipe 1. The rounded outer surface reduces the footprint of the soot particles and therefore is less prone to dust build-up on the insert 6, thereby providing better blockage prevention.
The inside of the plug-in 6 can be a solid structure or a hollow structure. When the hollow structure is adopted, the material can be saved, and the cost is reduced.
Further, as shown in fig. 7, the free end 61 of the insert 6 is beveled. The flowing direction of the smoke and dust particles flowing along the ash conveying pipeline 1 can be changed in the process of contacting with the inclined surface, but the change range is small, the probability of returning along the original path is reduced, and therefore the conveying efficiency of the smoke and dust particles in the ash conveying pipeline 1 cannot be greatly influenced.
