[0027] The present application embodiment discloses a powder feeding device, referring to Figure 1-2, including a tank body 1, the tank body 1 is square, the top of the tank body 1 is open, and the tank body 1 is made of 304 stainless steel, which is more corrosion-resistant and has a longer service life. At the same time, the side wall of the tank body 1 is connected with a standard feeding interface 3, and the standard feeding interface 3 is adapted to the powder tanker. After the powder tanker is connected with the standard feeding interface 3, the powder tanker can feed the material into the tank body 1 through the standard feeding interface 3. At the same time, the bottom of the tank body 1 is connected with a feeding pipe 4, and the side wall of the feeding pipe 4 is connected with two air pipes 41. The end of the air pipe 41 away from the feeding pipe 4 is connected with the air source, and the air outlet direction of the air pipe 41 is toward the feeding direction of the powder. The air pipe 41 is installed with a solenoid valve 42. When the powder enters the feeding pipe 4 under the action of gravity in the tank body 1, the solenoid valve 42 is opened, and the air source is blown into the feeding pipe 4 through the air pipe 41 to assist in blowing and feeding, thereby blowing the powder away faster and increasing the feeding speed. At the same time, the bottom of the tank body 1 is integrally formed with a cone 12, which is set in a cone shape. The large end of the cone 12 is connected to the bottom of the tank body 1, and the end of the feeding pipe 4 is connected to the small end of the cone 12. The cone 12 can facilitate the concentration of powder in the tank body 1 to the cone 12, so that the feeding can be better. In addition, a discharge valve 13 is installed between the small end of the cone 12 and the feeding pipe 4. The discharge valve 13 can facilitate the opening and closing of the bottom of the tank body 1. After the discharge valve 13 is opened, the powder can be fed into the feeding pipe 4. When the discharge valve 13 is closed, the feeding of the powder can be stopped.

[0028] In addition, a ton bag breaking knife 2 is provided in the tank body 1, and the ton bag breaking knife 2 is located at the upper part of the tank body 1. When the ton bag is used for feeding, the ton bag filled with powder is lifted to the top of the tank body 1, and then the ton bag is put down, and the ton bag breaking knife 2 is pierced to release the powder from the ton bag. At the same time, the ton bag breaking knife 2 includes a horizontal knife and a vertical knife, and the horizontal knife and the vertical knife are both arranged in a triangular shape, and the horizontal knife and the vertical knife are perpendicular to each other, and the corner of the top of the horizontal knife intersects with the corner of the top of the vertical knife, so that the ton bag breaking knife 2 can have a higher structural strength, and can better break the ton bag to make the break larger. In addition, a grille 5 is provided in the tank body 1. The grille 5 includes a plurality of crisscross horizontal and vertical grilles. The bottom of the horizontal knife is fixedly connected to the horizontal grille of the grille 5, and the bottom of the vertical knife is fixedly connected to the vertical grille of the grille 5. This makes the ton bag breaking knife 2 more secure, and the grille 5 can better support the ton bag, while allowing the powder to be released smoothly. At the same time, a convex edge is welded to the inner wall of the tank body 1, and the edge of the grille 5 is supported on the convex edge. A plurality of bolts are fixedly connected between the grille 5 and the convex edge. When the grille 5 needs to be replaced, the bolts are unscrewed to remove the grille 5 from the tank body 1.

[0029] In addition, a silo wall vibrator 6 is fixedly installed on the outer side wall of the tank body 1. Due to the different properties of the powder, sometimes the material is shed and sticky. The silo wall vibrator 6 can vibrate the tank body 1 and the powder in the tank body 1 to shake the powder off. In addition, a protective cover plate 11 is provided on the top of the tank body 1. The protective cover plate 11 covers the top of the tank body 1. One side of the protective cover plate 11 is hinged to the side wall of the tank body 1. The protective cover plate 11 is made of aluminum and is provided with a sealing strip. After adding powder into the tank body 1 or using a tank truck to deliver materials, the protective cover plate 11 is covered to prevent the powder from escaping.

[0030] The implementation principle of a powder feeding device in an embodiment of the present application is as follows: when a tank truck is used for feeding, the powder tank truck is connected to the standard feeding interface 3, the powder tank truck feeds the material into the tank body 1 through the standard feeding interface 3, and then the powder is fed through the feeding pipe 4, and the air blowing through the air pipe 41 can blow the powder away from the feeding pipe 4 to prevent the powder from accumulating in the feeding pipe 4; when a ton bag is used for feeding, the ton bag filled with powder is lifted to the top of the tank body 1, and then the ton bag is lowered, and the ton bag breaking knife 2 is used to pierce the ton bag, so that the powder is released from the ton bag, and the entire feeding process realizes automatic feeding without manual loading.

[0031] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
