[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] See also Figure 1 、 Figure 2 and Figure 3 A new type of tank truck feeding and blowing system includes an air compressor 1 and a powder tank truck 12. The output end of the air compressor 1 is connected to a first air storage tank 2 through a pipeline. The output of the first air storage tank 2 is connected to a dryer 3 through a pipeline. The output end of the dryer 3 is connected to a second air storage tank 4 through a pipeline. The output end of the second air storage tank 4 is connected to a Y-type filter 5 through a pipeline. The output end of the Y-type filter 5 is connected to a pressure reducing valve 6 through a pipeline. The air compressor 1 is used to pressurize the powder tank truck 12 so that it has a higher pressure and higher conveying kinetic energy when unloading, thereby increasing the conveying height and conveying distance. The compressed high-pressure gas is dried by the dryer 3 to remove moisture in the high-pressure gas, thereby preventing the high-pressure gas from causing the powder in the powder tank truck 12 to agglomerate, thereby affecting the unloading of the powder in the powder tank truck 12. The pressure reducing valve 6 is used to pressurize the powder tank truck 12 so that it has a higher pressure and higher conveying kinetic energy when unloading. The output end of the valve 6 is connected to a pressure gauge 11 through a pipeline. By designing a pressure reducing valve 6, a pressure gauge 11 and a pressure transmitter at the air inlet of the powder tanker 12, the pressure of the air supply to the powder tanker 12 is guaranteed to be ≤0.3MPa, thereby ensuring the safety of material charging. The pressure gauge 11 is connected to two powder tankers 12 through a pipeline. A gasification discharging system and a compressed air system are provided between the pressure gauge 11 and the powder tanker 12. The gasification discharging system is used to pressurize the interior of the powder tanker 12, squeeze out the material of the powder tanker 12, and discharge it through the blower 10. At the same time, the blower 10 is added during the conveying process to improve the conveying kinetic energy. The conveying pressure is increased by an external compressed air system, and the high-pressure gas is delivered to the blower 10, and the powder at the blower 10 is further pressurized, thereby increasing the conveying height and conveying distance.

[0023] See also Figure 1 、 Figure 2 and Figure 3The gasification discharging system and the compressed air system both include a check valve 7, a manual stop valve 8 and a quick connector 9. One end of the check valve 7 is connected to a pressure gauge 11 through a pipeline, and the other end of the check valve 7 is connected to a manual stop valve 8 through a pipeline. The manual stop valve 8 is connected to a quick connector 9 through a pipeline, and the quick connector 9 is connected to a powder tanker 12. A blower 10 is connected between the manual stop valve 8 and the quick connector 9 in the compressed air system. The gasification discharging system and the compressed air system of this system are connected to the powder tanker 12 through the quick connector 9, which is simple and convenient. A check valve 7 is provided on the pipeline connected to the powder tanker 12 to prevent backflow of the air source.

[0024] See also Figure 2 、 Figure 3 and Figure 4 The blower 10 includes an inlet 13, a contraction portion 14 and an outflow portion 15. The inner diameter of the inflow portion 13 is larger than that of the outflow portion 15, and the inner diameter of the outflow portion 15 is larger than that of the contraction portion 14. A flow-limiting orifice plate 16 is fixed between the inflow portion 13 and the contraction portion 14. A through-hole 19 is symmetrically provided on the outer wall of the outflow portion 15.

The blower 10 is a Venturi structure. The internal design of the flow-limiting orifice plate 16 of the blower 10 ensures that the gas source is stably replenished into the delivery pipeline and is slidably connected to the inside of the outflow portion 15. The adjusting column 17 can adjust the amount of compressed air for blowing by moving the adjusting column 17. An adjusting screw 20 is provided on the outside of the outflow portion 15. The left and right ends of the adjusting screw 20 are both slidingly connected to the outflow portion 15. The inner wall of the adjusting screw 20 is threadedly connected to the connecting rod 18. The left and right ends of the adjusting screw 20 are rotatably connected to the outflow portion 15 and the connection is sealed. The outer wall of the adjusting screw 20 is provided with anti-slip grooves. The diameter of the adjusting column 17 is the same as the inner diameter of the contraction portion 14. Anti-slip grooves are provided on the outer wall of the adjusting screw 20 to prevent hand slippage when rotating the adjusting screw 20 to adjust the adjusting column 17. At the same time, a sealing treatment is performed at the rotational connection between the adjusting screw 20 and the outflow portion 15 to prevent the gas of the blowing aid 10 from escaping and affecting the unloading effect.

[0025] When using this utility model:

[0026] The air compressor 1 generates high-pressure gas and stores it in the first gas storage tank 2. The high-pressure gas is dried by the dryer 3 to prevent the moisture in the gas from causing the powder to agglomerate. The dried high-pressure gas passes through the Y-type filter 5, the pressure reducing valve 6 and the pressure gauge 11 to the gasification discharge system and the compressed air system. The gasification discharge system is used to pressurize the interior of the powder tanker 12, squeeze out the material in the powder tanker 12, and discharge it through the blower 10. At the same time, the blower 10 is added during the conveying process to increase the conveying kinetic energy. The conveying pressure is increased by the external compressed air system, and the high-pressure gas is conveyed to the blower 10, further pressurizing the powder at the blower 10, thereby increasing the conveying height and distance.
