[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] like Figs. 1 to 3 As shown, this utility model discloses a powder ton bag feeding and screening system. The technical solution includes a vibrating screen 2 and an electric hoist 3. A lifting rod 4 is hung on the hook of the electric hoist 3, and two lifting lugs above the ton bag 1 containing calcium powder are hung at both ends of the lifting rod 4. The screen plate of the vibrating screen 2 is located directly below the outlet of the ton bag 1.

[0020] To prevent the powder from being released instantaneously due to static friction when the ton bag 1 is opened, causing the vibrating screen 2 below to be overloaded, a buffer pipe 6 is installed between the vibrating screen 2 and the ton bag 1 via a support 5. Neither the buffer pipe 6 nor the support 5 is in contact with the vibrating screen 2, and the lower opening of the ton bag 1 is located in the buffer pipe 6.

[0021] like Fig. 2 , Fig. 3 As shown, the main body of the buffer tube 6 is a tube body 602. The tube body 602 is set vertically and has openings at both the top and bottom. There is a ring plate 601 on the upper end face. The ring plate 601 has bolt holes 6011. By passing a screw through the bolt holes 6011 and screwing it onto the bracket 5, the buffer tube 6 can be fixed on the bracket 5.

[0022] The bottom surface of the buffer tube 6 has solar ribs 603, which are thin strips to support the powder. The friction between the solar ribs and the powder prevents the powder from being released quickly in a near-block form. Different shaped and sized discharge holes are opened on the solar ribs 603. Side holes 6021 are opened on the lower side of the tube body 602 to break the friction between the bottom and lower side of the powder, so that the powder gradually falls and is released. The discharge holes and side holes 6021 can make the powder evenly sprinkled on the screen of the vibrating screen 2 below.

[0023] To prevent the side hole 6021 from becoming clogged, a longitudinal elongated hole was adopted for the side hole 6021.

[0024] The working principle of this utility model:

[0025] The lifting lug of the ton bag 1 is hung on the lifting rod 4, the ton bag 1 is lifted by using the electric hoist 3, and is transported to above the buffer pipe 6; the discharge port below the ton bag 1 is opened, and the opening of the ton bag 1 enters the buffer pipe 6; the opening of the ton bag 1 is seated on the sun muscle 603, and contact with the screen of the vibrating screen 2 is avoided; the powder in the ton bag 1 is seated on the sun muscle 603, and instantaneous release is avoided under the action of the static friction force of the powder; the powder on the bottom falls through the discharge hole and the side hole 6021, and is scattered on the screen of the vibrating screen 2; since the falling speed of the powder is moderate, the vibrating screen 2 can perform screening treatment with high screening effect, and the normal working life of the vibrating screen 2 can be ensured, and the service life is not reduced due to overload operation.

[0026] The mechanical connection of the utility model relates to the usual means adopted by the person skilled in the art, and technical inspiration can be obtained through limited tests, and it belongs to the common general knowledge.

[0027] The components not described in detail in the present application are prior art.
