Description

Technical Field

[0001] This utility model relates to the field of powder batching technology, specifically to a powder batching machine. Background Technology

[0002] In the preparation of metal additives (raw material metal powder and co-solvent powder) or aluminum-based grain refiners (raw material potassium fluorotitanate and potassium fluoroaluminate), a powder batching machine is required. Typically, the bottom of the powder batching machine's cylinder is inverted conical. Powder is discharged from the bottom of the cylinder under gravity. Since the cross-sectional area of ​​the cylinder outlet is much smaller than the cross-sectional area of ​​the storage section above the cylinder, when the material falls to the smaller outlet position, the friction between the materials increases due to mutual compression. Irregularly shaped materials mesh with each other, leading to force balance and often causing arching in the hopper. This prevents the material from being discharged smoothly, affecting subsequent operations and production efficiency.

[0003] According to a public announcement of an arch-breaking device for a powder batching machine (Announcement No.: CN222240108U), the above application includes a batching cylinder and a blowing arch-breaking assembly. The blowing arch-breaking assembly includes an air supply pump, a connecting ring pipe, and an air supply branch pipe. The batching cylinder includes a storage chamber arranged in a straight cylindrical shape and a discharge chamber connected below the storage chamber. The discharge chamber is arranged in an inverted conical shape.

[0004] However, the aforementioned arch-breaking device has a belt drive in the powder silo, and the powder is very easy to scatter and settle on the belt and pulley device, causing dust to enter between the belt and pulley, aggravating wear or causing vibration, which seriously affects the operation of the whole machine; in view of this, we propose a powder batching machine. Utility Model Content

[0005] The purpose of this invention is to provide a powder batching machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder batching machine, comprising a batching cylinder, wherein a feed inlet is provided at the top of the batching cylinder, and an arch-breaking component is provided on the inner wall of the batching cylinder, the arch-breaking component comprising:

[0007] The motor has a rotating shaft fixedly connected to its output end, a rotating column fixedly connected to the bottom end of the rotating shaft, a conical block sleeved on the side wall of the rotating column, a convex ball fixedly connected to the bottom end face of the conical block, a crossbar fixedly connected to the side wall of the rotating shaft, and a helical rod fixedly connected to the bottom end face of the crossbar.

[0008] The bracket has a mounting base fixedly connected to its end face, and a disturbance block is fixedly connected to the top end face of the mounting base. An air inlet pipe is inserted into the inner wall of the dispensing cylinder.

[0009] Preferably, the motor is fixedly connected to the top end face of the mixing cylinder, and the cross-section of the rotating column is an equilateral hexagon.

[0010] Preferably, the top of the mounting base is arc-shaped, and the disturbance block is movably connected to the convex ball.

[0011] Preferably, the inner wall of the mixing cylinder is provided with an inclined groove, and the air inlet pipe abuts against the inner wall of the inclined groove.

[0012] Preferably, the bracket is fixedly connected to the inner wall of the mixing cylinder, and the air inlet pipe is fixedly connected to an external air blowing device, through which air is blown into the mixing cylinder to break up arches.

[0013] Preferably, there are two sets of spiral rods, which are symmetrically arranged on both sides of the crossbar, and the spiral rods continuously stir the powder in the mixing cylinder.

[0014] Preferably, a protrusion is fixedly connected to the inner wall of the dispensing cylinder, and a striking rod is fixedly connected to the side wall of the rotating shaft, with the striking rod being movably connected to the protrusion.

[0015] Compared with the prior art, the present invention provides a powder batching machine, which has the following beneficial effects:

[0016] 1. This powder batching machine, through its arch-breaking component, eliminates the need for a precise transmission structure within the batching cylinder, enhancing the long-term reliability of the system. It is suitable for continuous or harsh environments. The conical block continuously pushes the powder upwards, breaking down the arch structure formed inside the batching cylinder. The agitation of the spiral rod, while propelling the powder towards the outlet, also reduces internal friction and adhesion, enhancing its fluidity under gravity. The upward-blown airflow creates a spiral disturbance along the inner wall, impacting powder adhering to the wall and helping to break down arch structures or wall adhesion, improving overall material fluidity and preventing blockages caused by the powder's own weight or adhesion.

[0017] 2. This powder batching machine, through the setting of protrusions and striking rods, generates intermittent vibrations on the inner wall of the batching cylinder, further breaking the bridge structure, loosening the powder and allowing it to continue falling, maintaining the continuous and uniform falling of materials, improving the smoothness of the entire batching process, and reducing downtime and cleaning work caused by material blockage.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a powder batching machine, including a batching cylinder 1, a feed inlet 2 at the top of the batching cylinder 1, and an arch-breaking component 3 on the inner wall of the batching cylinder 1. The arch-breaking component 3 includes a motor 301, a rotating shaft 302, a rotating column 303, a conical block 304, a convex ball 305, a bracket 306, a mounting base 307, a disturbance block 308, an air inlet pipe 309, an inclined groove 310, a crossbar 311, and a spiral rod 312.

[0025] In one embodiment of this utility model, a motor 301 is fixedly connected to the top end face of the mixing cylinder 1. A rotating shaft 302 is fixedly connected to the output end of the motor 301. A rotating column 303 is fixedly connected to the bottom end of the rotating shaft 302. The rotating column 303 has an equilateral hexagonal cross-section. A conical block 304 is sleeved on the side wall of the rotating column 303. A convex ball 305 is fixedly connected to the bottom end face of the conical block 304. A crossbar 311 is fixedly connected to the side wall of the rotating shaft 302. A spiral rod 312 is fixedly connected to the bottom end face of the crossbar 311. Two sets of spiral rods 312 are provided, and the two sets of spiral rods 312 are symmetrically arranged on both sides of the crossbar 311. The spiral rods 312 continuously stir the powder in the mixing cylinder 1.

[0026] The bracket 306 is fixedly connected to the inner wall of the mixing cylinder 1. The end face of the bracket 306 is fixedly connected to the mounting base 307. The top end face of the mounting base 307 is fixedly connected to the disturbance block 308. The disturbance block 308 is movably connected to the convex ball 305. The inner wall of the mixing cylinder 1 is inserted with an air inlet pipe 309. The top of the mounting base 307 is arc-shaped. With the vibration generated by the intermittent knocking of the disturbance block 308 and the convex ball 305, the powder is prevented from accumulating on the top of the mounting base 307. The inner wall of the mixing cylinder 1 is provided with an inclined groove 310. The air inlet pipe 309 abuts against the inner wall of the inclined groove 310. The air inlet pipe 309 is fixedly connected to an external air blowing device. The external air blowing device blows air into the mixing cylinder 1 to break the arch. The air inlet pipe 309 continuously blows air from the outside to form a stable and continuous positive pressure airflow. The speed and pressure of the outward rush can prevent the powder from flowing back into the pipe and avoid it from accumulating at the pipe opening and causing blockage.

[0027] The motor 301 drives the rotating shaft 302 and the rotating column 303 to rotate, which in turn drives the conical block 304 to rotate, causing the convex ball 305 to continuously contact the disturbance block 308. The disturbance block 308 pushes the conical block 304 upward to bounce, causing the conical block 304 to continuously push the powder upward, breaking the arch bridge structure formed by the powder inside the batching cylinder 1. The rotation of the rotating shaft 302 drives the screw rod 312 to rotate, and the screw rod 312 continuously stirs the powder in the batching cylinder 1. The stirring action of the screw rod 312 not only pushes the powder to flow towards the discharge port, but also reduces the internal friction and adhesion of the powder, enhances its fluidity under gravity, and reduces material retention.

[0028] Air is blown into the mixing cylinder 1 through an external air blowing device and an air inlet pipe 309. The airflow is blown into the mixing cylinder 1 along the inclined groove 310, causing the airflow to blow obliquely upward along the inner wall of the mixing cylinder 1. The obliquely upward airflow forms a spiral disturbance along the inner wall, which disturbs and impacts the powder that is stuck against the wall. This helps to break the arch structure or wall adhesion phenomenon formed by the powder, improve the overall flowability of the material, and prevent the powder from clogging due to its own weight or adhesion. The mixing cylinder 1 is equipped with a precision transmission structure, which improves the reliability of the system in long-term operation and is suitable for continuous or harsh environments.

[0029] In addition, a protrusion 4 is fixedly connected to the inner wall of the batching cylinder 1, and a striking rod 5 is fixedly connected to the side wall of the rotating shaft 302. The striking rod 5 is movably connected to the protrusion 4. When the rotating shaft 302 rotates, it causes the striking rod 5 to rotate, so that the striking rod 5 contacts the protrusion 4, generating intermittent vibration on the inner wall of the batching cylinder 1. This further breaks the bridge structure, loosens the powder, and allows it to continue falling, maintaining continuous and uniform material falling, improving the smoothness of the entire batching process, and reducing downtime and cleaning work caused by material blockage.

[0030] In this utility model, during use, the motor 301 drives the rotating shaft 302 and the rotating column 303 to rotate, the conical block 304 rotates, and the disturbance block 308 pushes the conical block 304 upward to bounce, so that the conical block 304 continuously pushes the powder upward, destroying the arch bridge structure formed by the powder inside the mixing cylinder 1. The stirring action of the spiral rod 312 pushes the powder to flow towards the discharge port, while also reducing the internal friction and adhesion of the powder. The air blowing device and the air inlet pipe 309 blow air into the mixing cylinder 1. The airflow is blown into the mixing cylinder 1 along the inclined groove 310, so that the airflow blows obliquely upward along the inner wall of the mixing cylinder 1. The obliquely upward airflow forms a spiral disturbance along the inner wall, which disturbs and impacts the powder stuck against the wall, which helps to destroy the arch bridge structure or the phenomenon of sticking to the wall formed by the powder and improves the overall fluidity of the material.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
