Description

Technical Field

[0001] This utility model relates to the field of alumina powder technology, specifically to an alumina powder conveying device. Background Technology

[0002] Aluminum can be oxidized to produce alumina. Alumina powder is a powdery substance, also known as bauxite in mining, ceramics and materials science. In the production of alumina, an alumina powder conveying device is needed to transport the alumina powder.

[0003] For example, the "Conveying Device for Alumina Powder Production" with authorization announcement number "CN219129459U" mainly uses a motor to operate a conveying rod to transport alumina powder to the right. The alumina powder flows into a container placed inside the placement frame through a guide pipe on the lower side to collect the alumina powder. However, in actual use, because there is a certain gap between the bottom of the guide pipe and the placement frame, and because alumina powder is a powder, it is easy for it to overflow during the process of flowing into the container for collecting alumina powder. This causes some alumina powder to fall outside the container for collecting alumina powder, resulting in waste of alumina powder. Utility Model Content

[0004] The purpose of this invention is to provide an alumina powder conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an alumina powder conveying device, including a conveying frame, a hopper fixedly connected to the top of the conveying frame, a slide fixedly connected to the inner side of the bottom of the conveying frame, a transfer frame set at the slide of the conveying frame, a through pipe inserted into the bottom of the hopper, a movable pipe slidably connected to the bottom of the through pipe, an inlet pipe inserted into the top of the transfer frame, a flow limiting mechanism set inside the movable pipe, and a top rod fixedly connected to the inner side of the inlet pipe by a small rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model describes an alumina powder conveying device. Through the cooperation of structures such as a movable pipe, an inlet pipe, and a flow limiting mechanism, the alumina powder is kept inside the through pipe, movable pipe, and inlet pipe during its descent, preventing the alumina powder from overflowing when it flows into the transfer frame.

[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.

[0019] Please see Figure 1-4This embodiment provides an alumina powder conveying device, including a conveyor frame 1. A hopper 2 is fixedly connected to the top of the conveyor frame 1, and a slide 11 is fixedly connected to the inner side of the bottom end of the conveyor frame 1. A transfer frame 3 is set at the slide 11 on the conveyor frame 1. When in use, the transfer frame 3 is moved to the bottom end of the hopper 2 through the slide 11. At this time, the alumina powder in the hopper 2 can be transferred to the transfer frame, and the transfer frame 3 is conveyed by carrying the alumina powder inside it on the slide 11.

[0020] A through-tube 4 is inserted into the bottom of the hopper 2. A movable tube 5 is slidably connected to the bottom of the through-tube 4. An O-ring can be installed on the inner wall of the through-tube 4 to ensure the sealing between the through-tube 4 and the movable tube 5. An inlet tube 6 is inserted into the top of the transfer frame 3. A flow limiting mechanism 7 is installed on the inner side of the movable tube 5. A top rod 8 is fixedly connected to the inner side of the inlet tube 6 by a small rod. A stop block is fixedly connected to the inner side of the bottom of the transport frame 1. When the transfer frame 3 touches the stop block, the inlet tube 6 is exactly at the bottom of the movable tube 5. At this time, by sliding the movable tube 5 downward, the bottom end of the movable tube 5 is fitted onto the inlet tube 6, and the outer diameter of the inlet tube 6 is exactly the same as the inner diameter of the movable tube 5. As the movable tube 5 continues to slide downwards, the top of the push rod 8 presses against the flow-limiting mechanism 7, allowing the alumina powder in the hopper 2 to enter the transfer frame 3. After the alumina powder enters the transfer frame 3, the movable tube 5 slides upwards, moving away from the inlet tube 6. The push rod 8 does not press against the flow-limiting mechanism 7, thus limiting the flow of alumina powder under the action of the flow-limiting mechanism 7. This ensures that the alumina powder does not fall from the movable tube 5, keeping it inside the through tube 4, movable tube 5, and inlet tube 6 during its descent. This prevents the alumina powder from overflowing during its flow into the transfer frame 3, thereby avoiding waste of alumina powder.

[0021] The flow limiting mechanism 7 includes a connecting frame 71 fixedly connected to the inner wall of the movable tube 5. A baffle 72 is slidably connected to the bottom end of the connecting frame 71. The top end of the baffle 72 is designed with an inclination. A first elastic element 73 is provided between the baffle 72 and the connecting frame 71. The first elastic element 73 can be a spring or a sheet. The flow limiting mechanism 7 also includes a baffle frame 74 fixedly connected to the inner wall of the movable tube 5. When the bottom end of the movable tube 5 is fitted onto the inlet tube 6 and the movable tube 5 continues to slide downward, the push rod 8 can squeeze the baffle 72, compress the first elastic element 73, and the baffle 72 slides upward. At this time, there is a certain gap between the baffle 72 and the baffle frame 74, which allows the alumina powder to flow downward into the inlet tube 6 and the transfer frame 3. When the push rod 8 does not squeeze the flow limiting mechanism 7, the first elastic element 73 expands, allowing the baffle 72 to squeeze the baffle frame 74, ensuring that the alumina powder does not fall.

[0022] The top surface of the baffle 74 is inclined, and a sealing gasket 9 is bonded to the top surface of the baffle 74. The inclined design makes it easy for alumina powder to fall along the inclined direction by gravity. The design of the sealing gasket 9 ensures good sealing between the baffle 72 and the baffle 74 when the baffle 72 squeezes the baffle 74.

[0023] A second elastic element 10 is fixedly connected to the top of the movable tube 5. The top of the second elastic element 10 is fixedly connected to the hopper 2. A handle is fixedly connected to one side of the movable tube 5. The second elastic element 10 is a spring. The two ends of the spring are fixedly connected to the bottom of the movable tube 5 and the hopper 2, respectively. When the handle is held and the movable tube 5 is slid down, the second elastic element 10 is stretched. When the handle is released, the second elastic element 10 moves the movable tube 5 back to its original position under the action of the second elastic element 10, so that the movable tube 5 is away from the inlet tube 6 and does not affect the movement and conveying of the transfer frame 3.

[0024] The bottom of the transfer frame 3 is equipped with rollers. The outer edge of the rollers fits against the slide 11. The rollers are designed to facilitate the sliding of the transfer frame 3 on the slide 11. The rollers can be driven by a motor, so that the transfer frame 3 can move automatically for conveying.

[0025] A discharge pipe 12 is inserted into one side of the transfer frame 3, and an inclined plate 13 is attached to the inner side of the transfer frame 3. A driving component is provided at the top of the transfer frame 3. The driving component can be a servo electric cylinder. The servo electric cylinder is fixed at the top of the transfer frame 3. The output shaft of the servo electric cylinder passes through the transfer frame 3 and is fixedly connected to the inclined plate 13. When conveying, the output shaft of the servo electric cylinder extends and retracts, so that the inclined plate 13 is at the top of the discharge pipe 12. When it reaches the area that needs to be conveyed, the output shaft of the servo electric cylinder extends, so that the top of the inclined plate 13 is flush with the inner wall of the bottom end of the discharge pipe 12, so that the alumina powder can be discharged from the discharge pipe 12.
