Based on this, the utility model provides a new feeder for a pneumatic conveying system. Utility Model Content

[0006] Furthermore, the other end of the balancing rod passes through the other side wall of the shell, the other end of the breaking rod passes through the other side wall of the feed port, and the other end of the scattering rod passes through the other side wall of the discharge port. The output end of the driving motor and the other end of the balancing rod are fixedly connected by a coupling.
[0007] Furthermore, the gap between the material leveling blade and the inner wall of the shell is less than 0.5 mm.
[0008] Furthermore, the maximum distance between the material distribution blades is matched with the outlet end of the feed inlet and the inlet end of the discharge port.
[0009] Furthermore, the crushing blades arranged in the feed port are equidistantly arranged on the crushing rod.
[0010] Furthermore, the breaking rod is provided with breaking blades at equal intervals and placed in the discharge port.
[0011] The beneficial effects of the utility model are as follows: the utility model drives the turning of the balancing blades through the rotation of the balancing rod, so that the powdered material or small particle material can be continuously and evenly conveyed to the next equipment in the pneumatic conveying system; the rotation of the crushing blades is driven by the rotation of the breaking rod, so that the material added from the inlet end of the feed port can be broken up to prevent the materials from sticking together and causing the materials to accumulate in the feed port; the rotation of the breaking blades is driven by the rotation of the breaking rod, so that the materials falling downward from the inlet end of the discharge port can be broken up to prevent the materials from falling directly vertically downward and causing the discharge port to be blocked by too fast material flow; by using the same motor, the balancing rod, the breaking rod and the breaking rod can be driven to rotate at the same time under the transmission of the sprocket and the chain, thereby effectively reducing the overall cost and having good practicality.

One end passes through the other side wall of the discharge port 3, and the output end of the driving motor 6 is fixedly connected to the other end of the equalizing rod 4 by a coupling 11. Through the driving motor 6, under the connection of the coupling 11, the equalizing rod 4 is driven to rotate, and then the sprocket 9 on the equalizing rod 4 is driven to rotate. Under the transmission of the chain 10, the sprocket 9 on the crushing rod 7 and the sprocket 9 on the breaking rod 8 are driven to rotate, so that the crushing rod 7 and the breaking rod 8 are rotated. The rotation of the crushing rod 7 can crush the material added from the inlet end of the feed port 2 to prevent the materials from sticking together, thereby causing the materials to accumulate in the feed port 2. The rotation of the breaking rod 8 can scatter the materials falling downward from the inlet end of the discharge port 3 to prevent the materials from falling directly vertically downward, resulting in the situation where the material flow is too fast and blocks the discharge port 3.
[0019] As an optional embodiment, the gap between the material balancing blade 5 and the inner wall of the shell 1 is less than 0.5 mm, which effectively prevents the material from passing through the gap between the material balancing blade 5 and the inner wall of the shell 1 and affecting the material balancing effect.
[0020] As an optional embodiment, the maximum distance between the material-leveling blades 5 is matched with the outlet end of the feed port 2 and the inlet end of the discharge port 3, so that the powdery material or small particle material can be continuously and evenly conveyed to the next device in the pneumatic conveying system.
[0021] As an optional embodiment, crushing blades 12 are equidistantly arranged on the crushing rod 7 and placed in the feed port 2 to crush the powdered materials that are stuck together.
[0022] As an optional embodiment, the breaking rod 8 is provided with breaking blades 13 at equal intervals and placed in the discharge port 3, which play the role of breaking up the powdery materials or small particle materials that fall continuously and evenly downward.
[0023] Principle of the utility model
[0024] When in use, powdery materials or small particles are added into the shell 1 through the feed port 2, and the driving motor 6, under the connection of the coupling 11, drives the equalizing rod 4 to rotate, and then drives the sprocket 9 on the equalizing rod 4 to rotate, and under the transmission of the chain 10, drives the sprocket 9 on the crushing rod 7 and the sprocket 9 on the scattering rod 8 to rotate, so that the crushing rod 7 and the scattering rod 8 rotate, and the rotation of the equalizing rod 4 drives the equalizing blade 5 to flip, so that the powdery materials or small particles can be continuously and evenly conveyed to the next equipment in the pneumatic conveying system. The crushing blade 12 is driven to rotate by the rotation of the crushing rod 7, and the material added from the inlet end of the feed port 2 can be broken to prevent the materials from sticking together, thereby causing the materials to accumulate in the feed port 2. The scattering blade 13 is driven to rotate by the rotation of the scattering rod 8, and the material falling downward from the inlet end of the discharge port 3 can be broken to prevent the materials from falling directly vertically downward, resulting in the discharge port 3 being blocked by too fast material flow.
[0025] The utility model uses the same motor, and can drive the material balancing rod 4, the crushing rod 7 and the breaking rod 8 to rotate simultaneously under the transmission of the sprocket and the chain, thereby effectively reducing the overall cost and having good practicality.
[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
