Description

Technical Field

[0001] This invention relates to the field of high-temperature alumina powder storage, specifically to a high-temperature alumina powder post-production storage device and its usage method. Background Technology

[0002] Industrial alumina is prepared from bauxite and gibbsite. For alumina requiring high purity, chemical methods are generally used for preparation.

[0003] In existing technologies, alumina powder is heated during storage to evaporate moisture and prevent deterioration. However, existing equipment conducts heat to the powder through the inner wall of the storage chamber during drying. Since the alumina powder is cylindrically packed within the chamber, the powder in the center is relatively far from the inner wall, resulting in uneven heating and incomplete drying. This leads to deterioration of the alumina powder during storage. Summary of the Invention

[0004] The purpose of this invention is to provide a high-temperature alumina powder post-production storage device and its usage method, to solve the problem mentioned in the background art where alumina powder accumulates in a cylindrical shape in the storage bin, resulting in incomplete drying and deterioration of the alumina powder during storage. To achieve the above objective, this invention provides the following technical solution: a high-temperature alumina powder post-production storage device, comprising an outer cylinder, a bearing fixedly connected inside the outer cylinder, and an inner heating cylinder fixedly connected inside the bearing. The bottom surfaces of both the inner heating cylinder and the inner wall of the outer cylinder are concave. A conveying mechanism is rotatably connected to the bottom surface of the inner heating cylinder, and the conveying mechanism extends to the outside of the outer cylinder and is equipped with a discharge mechanism.

[0005] Preferably, the feeding mechanism includes a motor fixed to the top surface of the inner wall of the inner heating cylinder, an inner tube fixedly connected to the bottom end of the motor's rotating shaft, the lower end of the inner tube passing through the inner heating cylinder and the outer cylinder in sequence, a protective sleeve sleeved on the side of the inner tube, and the protective sleeve rotatably connected to the inner heating cylinder, and a spiral blade fixedly connected to the inner wall of the inner tube.

[0006] The inner tube has a discharge port and a feed port on its side. The feed port is located between the outer wall of the inner heating cylinder and the inner wall of the outer cylinder. The discharge port is located inside the inner heating cylinder. The discharge port is in contact with an upper cover plate. One end of the upper cover plate is fixedly connected to a connecting shaft. The connecting shaft is hinged to the outside of the inner tube. The lower end of the connecting shaft extends to the lower side of the inner heating cylinder and is fixedly connected to a flow guide cover plate. The flow guide cover plate is located outside the feed port. A transmission plate is fixedly connected to the side of the flow guide cover plate.

[0007] The upper side of the transmission plate abuts against the rotating tube, the bottom surface of the rotating tube is inserted with a friction column, and the top of the friction column abuts against the outer wall of the inner heating cylinder. The bottom end of the friction column is fixedly connected to a limit frame, and a pressure plate is slidably arranged on the inner side of the limit frame. The side of the pressure plate is hinged to the bottom surface of the rotating tube, and a spring telescopic rod is hinged between the pressure plate and the limit frame.

[0008] Preferably, the discharge mechanism includes a ring fixedly sleeved on the bottom of the outer side of the inner tube, an arc-shaped toothed plate fixedly connected to the outer side of the ring, and arc-shaped rods fixedly connected to both ends of the arc-shaped toothed plate;

[0009] The side of the arc-shaped toothed plate is engaged with a gear, the top surface of the gear is fixedly connected to an annular plate, and the annular plate is rotatably connected to the bottom surface of the outer cylinder. A contact post is movably inserted into the bottom surface of the annular plate, one end of the contact post abuts against the outer wall of the outer cylinder, and a C-shaped frame is fixedly connected to the bottom end of the contact post. Two trigger plates are slidably connected to the inner side of the C-shaped frame, and the surface of the trigger plate abuts against the surface of the arc-shaped rod. The side of the trigger plate is hinged to the bottom surface of the annular plate, and a return spring is fixedly connected between the trigger plate and the annular plate.

[0010] A sealing blade is fixedly connected to the lower end face of the gear, and the top surface of the sealing blade abuts against the bottom end of the inner tube.

[0011] Preferably, the number of sealing blades is five, and the five sealing blades form a circle to seal the bottom end of the inner tube.

[0012] Preferably, the top surface of the inner heating cylinder is conical, and the apex of the cone of the inner heating cylinder is on the central axis of the outer cylinder.

[0013] Preferably, the flow guide cover plate is arc-shaped, and a baffle is fixedly connected to the inner side of the flow guide cover plate, and the baffle slides on the upper side of the inner wall of the feed inlet.

[0014] Preferably, the outer corner of the top surface of the inner tube is rounded.

[0015] Preferably, the method of using the high-temperature alumina powder post-production storage equipment includes the following steps:

[0016] S1: When storing high-temperature alumina powder, the user heats it up through the inner heating cylinder, and then opens the outer cylinder and injects high-temperature alumina powder into it. At this time, the high-temperature alumina powder flows in an umbrella shape along the outside of the inner heating cylinder between the inner heating cylinder and the outer cylinder and gathers on the bottom surface of the inner wall of the outer cylinder, thus avoiding the presence of water vapor on the high-temperature alumina powder.

[0017] S2: At this time, the motor drives the inner tube to rotate clockwise. When the transmission plate slides on the bottom surface of the rotating tube, the resistance of the rotating tube causes the guide cover plate to deflect and open the feed port. The upper cover plate is driven to deflect synchronously through the connecting shaft to cover the discharge port. When the transmission plate deflects and touches the pressure plate, the pressure plate is squeezed and deflected, causing the upper end of the friction column on the limit frame to move down and separate from the bottom surface of the outer wall of the inner heating cylinder. The rotating tube rotates synchronously with the transmission plate. The guide cover plate squeezes the high-temperature alumina powder into the feed port and continuously conveys it to the spiral blades. The spiral blades convey the high-temperature alumina powder to the upper end of the inner tube and guide it into the interior of the inner heating cylinder. This process is continued to store the high-temperature alumina powder.

[0018] Furthermore, when the inner tube rotates clockwise, the ring at its lower end rotates clockwise simultaneously, causing the arc-shaped toothed plate to push the upper arc surface of the arc rod to apply pressure to the trigger plate, causing the contact column to separate from the outer wall of the outer cylinder. At this time, the ring plate rotates clockwise along with the inner tube.

[0019] S3: When the device needs to discharge material, the motor drives the inner tube to rotate counterclockwise. At this time, when the transmission plate slides on the bottom surface of the rotating tube, the resistance of the rotating tube causes the guide cover plate to deflect and block the inlet. When the guide cover plate deflects, it simultaneously drives the upper cover plate to deflect and open the outlet. At the same time as the outlet opens, the ring at its lower end rotates counterclockwise, causing the arc rod to deflect counterclockwise, causing the arc rod to separate from the trigger plate first. Then, the contact column abuts against the outer wall of the outer cylinder to fix the trigger plate. At this time, the arc toothed plate deflects counterclockwise, causing the gear to rotate, causing the sealing blade to deflect and open. Then, the upper cover plate, which rotates counterclockwise with the inner tube, scrapes the high-temperature alumina powder inside the inner heating cylinder into the inner tube and conveys it along the inside of the inner tube to the outside of the inner heating cylinder, realizing the discharge of high-temperature alumina powder by the device.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In this invention, heat is generated by an inner heating cylinder, and then high-temperature alumina powder is injected into the outer cylinder by opening it. At this time, the high-temperature alumina powder flows in an umbrella-like pattern along the outside of the inner heating cylinder between the inner heating cylinder and the outer cylinder and gathers on the bottom surface of the inner wall of the outer cylinder. This increases the uniformity of drying the high-temperature alumina powder by the device, avoids the presence of moisture on the high-temperature alumina powder, and prevents the high-temperature alumina powder from deteriorating.

[0022] In this invention, the inner tube is driven to rotate clockwise by a motor. When the transmission plate slides on the bottom surface of the rotating tube, the resistance of the rotating tube causes the guide cover plate to deflect and open the feed port. The upper cover plate is driven to deflect synchronously through the connecting shaft to cover the discharge port. When the transmission plate deflects and abuts against the pressure plate, the pressure plate is squeezed and deflected, causing the upper end of the friction column on the limit frame to move down and separate from the bottom surface of the outer wall of the inner heating cylinder. The rotating tube rotates synchronously with the transmission plate. The guide cover plate squeezes the high-temperature alumina powder into the feed port and continuously conveys it to the spiral blades. The spiral blades then convey the high-temperature alumina powder to the upper end of the inner tube and guide it into the interior of the inner heating cylinder. This process is continued to store the high-temperature alumina powder. The double protection of the outer cylinder and the inner heating cylinder increases the protection effect of the device for the high-temperature alumina powder.

[0023] In this invention, the inner tube is driven to rotate counterclockwise by a motor. When the transmission plate slides on the bottom surface of the rotating tube, the resistance of the rotating tube causes the guide cover plate to deflect and block the feed inlet. At the same time, the deflection of the guide cover plate drives the upper cover plate to deflect and open the discharge port. Simultaneously, the ring at the lower end of the discharge port rotates counterclockwise, causing the arc rod to deflect counterclockwise. This causes the arc rod to separate from the trigger plate first, and then the contact post abuts against the outer wall of the outer cylinder to fix the trigger plate. At this time, the arc toothed plate deflects counterclockwise, causing the gear to rotate and causing the sealing blade to deflect and open. The upper cover plate, which rotates counterclockwise with the inner tube, scrapes the high-temperature alumina powder inside the inner heating cylinder into the inner tube and conveys it from the inside of the inner tube to the outside of the inner heating cylinder, thus realizing the discharge of the high-temperature alumina powder by the device.

[0047] In this embodiment, as Figure 5 and Figure 6 As shown, the outer corner of the top surface of the inner tube 32 is rounded.

[0048] The method of use and advantages of this invention: The method of using this high-temperature alumina powder post-production storage equipment is as follows:

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown:

[0050] S1: When storing high-temperature alumina powder, the user heats it up through the inner heating cylinder 2, and then opens the outer cylinder 1 and injects high-temperature alumina powder into it. At this time, the high-temperature alumina powder flows in an umbrella shape along the outside of the inner heating cylinder 2 between the inner heating cylinder 2 and the outer cylinder 1 and gathers on the bottom surface of the inner wall of the outer cylinder 1, so as to avoid the high-temperature alumina powder containing water vapor.

[0051] S2: At this time, the inner tube 32 is rotated clockwise by the motor 31. When the transmission plate 39 slides on the bottom surface of the rotating tube 310, it is resisted by the rotating tube 310 and causes the guide cover plate 38 to deflect and open the feed port 35. The upper cover plate 36 is driven to deflect synchronously through the connecting shaft 37 to cover the discharge port 34. When the transmission plate 39 deflects and abuts against the pressure plate 313, the pressure plate 313 is squeezed and deflected, causing the upper end of the friction column 311 on the limit frame 312 to move down and separate from the bottom surface of the outer wall of the inner heating cylinder 2. The rotating tube 310 rotates synchronously with the transmission plate 39. The high temperature alumina powder is squeezed into the feed port 35 through the guide cover plate 38 and continuously transported to the spiral blade 33. The high temperature alumina powder is transported to the upper end of the inner tube 32 through the spiral blade 33 and guided into the interior of the inner heating cylinder 2. This process is continued to store the high temperature alumina powder.

[0052] Furthermore, when the inner tube 32 rotates clockwise, the ring 41 at its lower end rotates clockwise simultaneously, causing the arc-shaped toothed plate 42 to push the upper arc surface of the arc rod 43 to apply pressure to the trigger plate 48, causing the contact post 46 to separate from the outer wall of the outer cylinder 1. At this time, the annular plate 45 rotates clockwise along with the inner tube 32.

[0053] S3: When the device needs to discharge material, the motor 31 drives the inner tube 32 to rotate counterclockwise. At this time, when the transmission plate 39 slides on the bottom surface of the rotating tube 310, the resistance of the rotating tube 310 causes the guide cover plate 38 to deflect and block the inlet 35. When the guide cover plate 38 deflects, it simultaneously drives the upper cover plate 36 to deflect and open the outlet 34. At the same time as the outlet 34 opens, the ring 41 at its lower end rotates counterclockwise, causing the arc rod 43 to deflect counterclockwise, thus causing the arc... The face rod 43 first separates from the trigger plate 48, and then the contact column 46 abuts against the outer wall of the outer cylinder 1 to fix the trigger plate 48. At this time, the arc-shaped toothed plate 42 deflects counterclockwise, driving the gear 44 to rotate, causing the sealing blade 410 to deflect and open. At this time, the upper cover plate 36, which rotates counterclockwise with the inner tube 32, scrapes the high-temperature alumina powder inside the inner heating cylinder 2 into the inner tube 32, and conveys it along the inner tube 32 to the outside of the inner heating cylinder 2, realizing the discharge of high-temperature alumina powder by the device.

[0054] After the sealing blade 410 deflects and opens, the arc-shaped toothed plate 42 pushes the upper arc surface of the arc rod 43 to apply pressure to the trigger plate 48, causing the contact post 46 to separate from the outer wall of the outer cylinder 1. At this time, the annular plate 45 is in the open state and rotates clockwise with the inner tube 32.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

The rod (43) first separates from the trigger plate (48), and then the abutting column (46) abuts against the outer wall of the outer cylinder (1) to fix the trigger plate (48). At this time, the arc-shaped toothed plate (42) deflects counterclockwise, driving the gear (44) to rotate, causing the sealing blade (410) to deflect and open. At this time, the upper cover plate (36) that follows the inner tube (32) to rotate counterclockwise scrapes the high-temperature alumina powder inside the inner heating cylinder (2) into the inner tube (32) and conveys it along the inner tube (32) to the outside of the inner heating cylinder (2), realizing the discharge of high-temperature alumina powder by the device.
