Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder material conveying, in particular to a powder material pneumatic conveying device. Background Art

Therefore, a powder pneumatic conveying device is needed to meet the needs. Utility Model Content

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Example 1: Reference Figure 1-3The pneumatic conveying device for powder comprises a fixed frame 1, on which a pressurized tank 2 is fixed, and an air inlet pipe 5 and a discharge pipe 3 are connected and fixed to the pressurized tank 2 at the top and bottom, respectively, and an air compressor and a control valve 4 are fixed to the air inlet pipe 5 and the discharge pipe 3, respectively. The air compressor increases the pressure in the pressurized tank 2 through the air inlet pipe 5, and when the pressure is increased to a preset value, the passage of the air inlet pipe 5 is closed, so that the powder in the pressurized tank 2 will not enter the air inlet pipe 5, ensuring that no powder will be wasted, a gate valve 6 is fixed on the pressurized tank 2, and a first hopper 7 is fixed on the gate valve 6, and the powder is intermittently added to the pressurized tank 2 through the first hopper 7 through the opening and closing of the gate valve 6, so that the accidental situation of adding too much powder to the pressurized tank 2 at one time can be avoided, thereby ensuring the safe use of the pressurized tank 2.
[0019] When in use, the powder is added into the first hopper 7, and then the gate valve 6 is opened to allow the powder to fall from the first hopper 7 into the pressurized tank 2, and then the gate valve 6 is closed, and the air compressor is used to pressurize the inside of the pressurized tank 2 through the air inlet pipe 5. When the preset pressure is reached in the pressurized tank 2, the control valve 4 is opened, and under the action of high pressure, the powder in the pressurized tank 2 is transported to the high-altitude equipment through the discharge pipe 3, and under the action of high pressure, the powder is broken up at the moment of being discharged through the discharge pipe 3, so that the powder transported to the high-altitude equipment will not clump and will not affect the use of the powder.
[0020] Embodiment 2: In embodiment 1, due to the support of the fixing frame 1 and the pressurized tank 2, the height of the first hopper 7 is relatively high, and it is still very laborious to load materials into the first hopper 7. Figure 1-3 As another preferred embodiment of the utility model, the difference from embodiment 1 is that a feeding mechanism is fixed on the first hopper 7, and the feeding mechanism includes a cylinder 10, and the cylinder 10 is connected and obliquely fixed to the second conveying pipe 13 and the first conveying pipe 12 respectively at the upper and lower parts, and the second conveying pipe 13 is connected and fixed to the first hopper 7, and the first conveying pipe 12 is connected and fixed to the second hopper 11, and the second hopper 11 is fixed on the cylinder 10, and a rotating shaft 15 is provided inside the cylinder 10 for rotation, and a motor 14 and a spiral blade 16 are fixed on the rotating shaft 15, and the spiral blade 16 is in contact with the inner wall of the cylinder 10, and the motor 14 drives the spiral blade 16 to rotate in the cylinder 10 through the rotating shaft 15, and then the powder at the bottom of the cylinder 10 is conveyed to the second conveying pipe 13 by the rotating spiral blade 16;
[0021] The cylinder 10 is fixed with a first connecting frame 8 and a second connecting frame 9, which are respectively fixed to the first hopper 7 and the pressurized tank 2. With the assistance of the first connecting frame 8 and the second connecting frame 9, the position of the cylinder 10 is processed so that the cylinder 10 can be used more stably.
[0022] When in use, a worker standing on the ground can add powder into the second hopper 11. With the help of the powder's own weight, the powder in the second hopper 11 is transported to the cylinder 10 through the inclined first conveying pipe 12. The powder entering the cylinder 10 is continuously transported to the second conveying pipe 13 driven by the rotating spiral blades 16, which not only prevents the first conveying pipe 12 from being blocked by powder, but also allows the powder at a lower location to be transported to the higher first hopper 7 through the second conveying pipe 13, thereby reducing the labor intensity of the workers. In addition, even if there is a light agglomeration of powder when it enters the first hopper 7, it can be broken up during the subsequent high-pressure pneumatic conveying process, which will not affect the use of the powder.
[0023] Embodiment 3: In embodiment 2, since the spiral blade 16 squeezes the powder, it is easy to cause the powder to agglomerate, which makes it easy for the powder to be blocked when passing through the second conveying pipe 13, which is not conducive to the smooth conveying of the powder. Figure 1-4 As another preferred embodiment of the utility model, the difference from embodiment 1 is that an electric telescopic rod 17 is passed through and sealed on the first hopper 7, a fixed rod 18 is fixed on the push rod of the electric telescopic rod 17, and a dredging block 19 is fixed on the fixed rod 18. The electric telescopic rod 17 can insert the dredging block 19 into the second conveying pipe 13 through the fixed rod 18, so that the dredging block 19 can dredge the slightly blocked powder in the second conveying pipe 13. The dredging block 19 is a conical structure, and the dredging block 19 and the second conveying pipe 13 are arranged coaxially. When the dredging block 19 with a conical structure moves, it will not contact the inner side wall of the second conveying pipe 13, and reserve space for the loosened powder to pass through, thereby ensuring smooth dredging of the powder in the second conveying pipe 13.
[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
