A powder tanker with a blowing-assisting device comprises a powder tanker body, wherein the powder tanker body comprises at least two material conveying pipes 1, a connector 2 and a blowing-assisting device 3 (shown in figure 1). In the embodiment, there are two material conveying pipes 1, including a first conveying pipe 11 and a second conveying pipe 12; the joint 2 is provided with a first connecting port 211, a second connecting port 221 and a third connecting port 23 which are coaxially arranged, the third connecting port 23 is arranged below the axis, the inner cavity 24 is used for communicating the material conveying pipe 1 with the blowing assisting device 3, the first connecting port 211 is welded with the first conveying pipe 11, the connecting end part of the first conveying pipe 11 extends into the inner cavity 24 of the joint 2, and the second connecting port 221 is welded with the second conveying pipe 12; the blowing assisting device 3 is arranged below a horizontal plane where the joint 2 is located, the two ends of the blowing assisting device are respectively provided with a gas inlet 311 and a gas outlet 312, the gas inlet 311 is used for being connected with an external gas conveying device, and the gas outlet 312 faces to a gap formed by the outer side wall, extending into the inner cavity 24, of the first conveying pipe 11 and the inner side wall of the inner cavity 24 and is welded with the third connecting port 23. In use, the first transfer tube 11 transfers material into the other end face of the first transfer tube 11 opposite to the end face located in the cavity 24 of the connector 2, the material flowing along the first transfer tube 11, the connector 2 and the second transfer tube 12. In the structure, the air outlet 312 of the blowing assisting device 3 faces the material conveying direction, so that air and materials are mixed, the material conveying speed is increased, and the discharging efficiency is improved. Extending the end of the first conveying pipe 11 into the inner cavity 24 of the joint 2 largely avoids material being deposited at the bottom of the inner cavity 24 of the joint 2 during the conveying process, which effectively prevents clogging. In addition, the blowing-assisting device 3 is arranged below the interface, and can blow the material deposited at the bottom of the joint 2 into the material conveying pipe 1, so that the material is further prevented from being deposited and blocked in the conveying pipe.

As an improved scheme, as shown in fig. 2, the projection of the blowing-assisting device 3 in the extending direction of the inner cavity 24 is located on the first conveying pipe 11, and the projection of the blowing-assisting device 3 is located on the first conveying pipe 11, so that in the working process of the blowing-assisting device 3, the gas is blown to the space between the outer side wall of the first conveying pipe 11 and the inner wall of the joint 2, and then the gas can only move in the material conveying direction (the side of the second connecting port 221), and the problem that the material conveying speed and the discharging efficiency are reduced due to turbulent flow and even backflow of the gas in the inner cavity 24 of the joint 2 is avoided.

As a modification, as shown in fig. 1-2, the end of the first delivery tube 11 located in the inner chamber 24 is close to the second connection port 221. In this way, during the material transportation process, the material is prevented from depositing on the bottom of the inner cavity 24 of the connector 2 during the transportation process, which can effectively prevent blockage.

As a modification, as shown in fig. 3 to 4, the radial cross section of the joint 2 is a closed circular arc, and the diameter of the radial cross section in the direction from the first connection port 211 to the second connection port 221 gradually increases and then gradually decreases. Preferably, the joint 2 comprises a first joint 21 and a second joint 22, both of which are circular in radial section; one end of the first joint 21 is provided with a first connecting port 211, and the other end is provided with a third connecting port 23; the second joint 22 has a second connection port 221 at one end thereof, a fourth connection port welded to the third connection port 23 at the other end thereof, and the third connection port 23 and the fourth connection port have the largest diameters in radial cross section. The caliber of the radial section of the joint 2 is set to be a simple circle, so that the circulation resistance of gas in the inner cavity 24 of the joint 2 is avoided, and the phenomena of turbulence and backflow in the inner cavity 24 of the joint 2 are avoided, thereby being beneficial to improving the conveying speed of materials and improving the conveying efficiency.

In the above embodiment, it should be noted that the diameter of the radial cross section of the joint 2 in the direction from the first connection port 211 to the second connection port 221 gradually increases and then gradually decreases, that is, the diameter thereof gradually increases and then decreases; the above distribution is, as viewed in an axial cross section, a distribution of which is shown as an arcuate line in fig. 1. It should be noted that the first joint 21 and the second joint 22 may be integrally formed parts, and the radial cross section of the first joint and the second joint may be changed by several degrees, so long as the gas flow resistance is reduced and the turbulence phenomenon is generated.

As a modification, as shown in fig. 1, the horizontal plane of the joint 2 is at an angle of less than 90 ° to the blowing-aid device 3. In the actual use process, the smaller the included angle between the horizontal plane of the joint 2 and the blowing-assisting device 3 is, the more directly the gas can be blown into the second connecting port 221, the lower the flow resistance in the inner cavity 24 of the joint 2 is, and the problem of low use efficiency of the blowing-assisting device is solved.

As an improved scheme, as shown in fig. 1, the blowing-assisting device 3 includes a gas pipe 31 and a ball valve 32 connected in series in the gas pipe 31, two ends of the gas pipe 31 are respectively a gas inlet 311 and a gas outlet 312, the gas inlet 311 is used for being connected with an external gas conveying device, and the gas outlet 312 faces the material conveying direction and is connected with the third connecting port 23. The ball valve 32 in the air pipe 31 can conveniently control the on-off of the blowing-assisting device 3, thereby being convenient for users to use. In addition, a one-way check valve 33 is further arranged on the side close to the third connecting port 23, so that even if a user forgets to close the ball valve 32, the one-way check valve 33 can prevent the material in the material conveying pipe 1 from flowing back to the pipeline of the blowing-assisting device 3, and the possibility of blockage caused by the fact that the material enters the pipeline of the blowing-assisting device 3 due to forgetting to close the ball valve 32 by human error is avoided.

As a modified scheme, as shown in fig. 4, the end face of the first conveying pipe 11 in the inner cavity 24 is taken as a cross section (i.e., a cross section a-a in fig. 1), and the material conveying direction is taken as a projection direction, the projection of the second joint 22 and the first conveying pipe 11 is annular, and the annular area S is equal to half of the sum of the radial cross-sectional areas of the air conveying pipe 31 and the second conveying pipe 12. Therefore, the generation of turbulent flow and even backflow phenomenon of the gas in the blowing assisting process is reduced, the circulation resistance is reduced, the efficiency loss of the blowing assisting device 3 is avoided, and the unloading efficiency is improved.
