[0030] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0031] An intelligent powder pneumatic pressure conveying tank comprises a tank body 1, which is a teardrop-shaped structure, and the lower part is buried in the ground of an external factory building. A feed pipe 2 is provided at one end of the top of the tank body 1, and a gas main pipe 4 is provided on the outside of the tank body 1. The output end of the gas main pipe 4 is connected to a guide pipe 5, and the top of the guide pipe 5 is connected to a first gas branch pipe 6, and the outside of the guide pipe 5 and one end close to the first gas branch pipe 6 are connected to a second gas branch pipe 7, and the bottom of the guide pipe 5 is connected to a third gas branch pipe 8. The output end of the first gas branch pipe 6 is connected to the top of the tank body 1, the output end of the second gas branch pipe 7 is connected to one side of the feed pipe 2, and the output end of the third gas branch pipe 8 is connected to the bottom of the tank body 1. A discharge pipe 13 is connected to the middle of the bottom of the tank body 1, and a backwash pipe 14 is connected to the bottom of the tank body 1 and one end away from the third gas branch pipe 8.

[0032] Specifically, the powder enters the tank body 1 from the feed pipe 2, and the volume of the powder is detected by the material level detection mechanism 17 to determine when the feeding is completed. After the feeding is completed, a high-pressure airflow is pumped into the gas main pipe 4 and output in sequence through the first gas branch pipe 6, the second gas branch pipe 7 and the third gas branch pipe 8 to pressurize the powder. After being pressed by the high-pressure airflow, the powder flows out through the discharge pipe 13 and is output to the external silo, automatically completing the quantitative pressure-holding and conveying of the powder, saving time and effort. At the same time, since the lower part of the tank body 1 is buried in the ground of the external factory building, the floor area is reduced, so that the pipeline transportation is carried out entirely underground, and dust pollution and noise pollution will not be generated. Again, compared with the traditional elevator feeding method, the height requirement for the factory building is greatly reduced, protecting the factory building environment.

[0033] Furthermore, the input end of the feed pipe 2 is connected to an external pumping device, and a feed solenoid valve 3 is also provided on the outside of the feed pipe 2 to facilitate the control of the input and stop of the powder.

[0034] Furthermore, a first ball valve 9 is installed on the outside of the first gas branch pipe 6 to facilitate control of the first gas branch pipe 6, a first water hammer eliminator 10 is installed on the outside of the second gas branch pipe 7, and a second water hammer eliminator 11 is installed at the lower outside of the guide pipe 5 to facilitate slight buffering of the high-pressure airflow, reduce the impact force of the airflow on the pipeline, and increase the service life of the pipeline.

[0035] Furthermore, a second ball valve 12 is installed in the middle of the outer side of the gas transmission main pipe 4 to facilitate the control of the gas transmission main pipe 4 .

[0036] Furthermore, a third water hammer arrester is installed on the outside of the gas main pipe 4 and on one side of the second ball valve 12, so as to further slightly buffer the high-pressure airflow and protect the gas pipeline. A pipeline pressure sensor is also installed on the outside of the gas main pipe 4 and on the side of the third water hammer arrester away from the second ball valve 12, so as to monitor the pipeline gas pressure.

[0037] Furthermore, the bottom of the discharge pipe 13 is connected to the external silo through a pipeline, and a discharge solenoid valve 15 is installed in the middle of the outer side of the discharge pipe 13 to facilitate better discharge of the powder.

[0038] Furthermore, the backwash pipe 14 is connected to an external backwash device, and a backwash solenoid valve 16 is installed in the middle of the outer side of the backwash pipe 14 to facilitate better backwashing of the tank body 1.

[0039] Furthermore, a material level detection mechanism 17 is provided inside the tank body 1 , and the material level detection mechanism 17 is used to detect the volume of powder in the tank body 1 .

[0040] Furthermore, the material level detection mechanism 17 includes a screw rod 171, which is rotatably connected to one side of the interior of the tank body 1, and a slide rod 172 is fixedly installed on one side of the interior of the tank body 1. A lifting plate 173 is slidably connected to the outer side of the slide rod 172, and one end of the lifting plate 173 is threadedly connected to the screw rod 171. A material level meter 174 is fixedly installed on one end of the lifting plate 173 close to the middle of the tank body 1. A dust cover 175 is installed on one side of the tank body 1, and a rotating plate 176 is rotatably connected to the top of the dust cover 175. The top of the screw rod 171 extends to the interior of the dust cover 175 and is fixedly connected to a universal shaft 177, and the other end of the universal shaft 177 is coaxially connected to the rotating plate 176.

[0041] Specifically, when the level meter 174 rises or falls, the powder detection volume in the tank body 1 can be increased or decreased. First, the rotating plate 176 can be rotated to drive the screw 171 to rotate through the universal shaft 177, thereby driving the lifting plate 173 to rise or fall. The lifting and lowering of the lifting plate 173 drives the level meter 174 to rise and fall at the same time. When the level meter 174 rises, it means that the volume of the powder transported in the tank body 1 at a single time has increased, and vice versa, it means that the volume of the powder transported in the tank body 1 at a single time has decreased. When the material reaches the detection position of the level meter 174, it means that the powder volume has reached the requirement, the feeding stops, and the discharge is ready.

[0042] Furthermore, a PLC controller is provided outside the tank body 1, and the PLC controller is electrically connected to the feed solenoid valve 3, the discharge solenoid valve 15, the back-blowing solenoid valve 16 and the material level meter 174, respectively, so as to better control the equipment.

[0043] In this embodiment, first, the feed solenoid valve 3 is opened, the discharge solenoid valve 15 and the back-blowing solenoid valve 16 are closed, and the powder enters the tank body 1 from the feed pipe 2 through the external screw conveyor, and the powder volume is detected by the material level detection mechanism 17. After detecting that the powder volume meets the requirements, the feeding is completed, and the feed solenoid valve 3 is closed, the discharge solenoid valve 15 is opened, and the back-blowing solenoid valve 16 is closed. Then the gas main pipe 4 pumps in high-pressure airflow and outputs it through the first gas branch pipe 6, the second gas branch pipe 7 and the third gas branch pipe 8 in sequence, and the powder is pressurized. After being pressurized by the high-pressure airflow, the powder flows out through the discharge pipe 13 and is output to the external silo, automatically completing the quantitative powder pressure conveying, saving time and effort. After the powder in the tank body 1 is transported, the above operation can be repeated to transport the next batch of powder. After the tank body 1 is used up, it can be backwashed through the backwashing pipe 14. At this time, the feed solenoid valve 3 is closed, the discharge solenoid valve 15 and the backwashing solenoid valve 16 are opened, and then the backwashing pipe 14 pumps high-pressure backwashing airflow into the tank body 1 to backwash the tank body 1. The backwashing airflow and residual powder flow out through the discharge pipe 13. Since the lower part of the tank body 1 is buried in the ground of the external factory building, the floor area is reduced, so that the pipeline transportation is carried out entirely underground, and no dust pollution and noise pollution are generated. Again, compared with the traditional elevator feeding method, the height requirement of the factory building is greatly reduced, protecting the factory building environment.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
