Abstract
Description
Technical Field
[0001] This utility model relates to the field of alumina powder processing, and in particular to an alumina powder feeding and conveying device. Background Technology
[0002] Alumina powder is a common industrial raw material, appearing as a white, amorphous powder with high hardness and a high melting point. It is widely used in metallurgy, ceramics, chemical and other industries. During its production and use, conveying devices are often required to transfer and feed the material to meet the needs of continuous production.
[0003] Traditional feeding and conveying devices have significant drawbacks in the transfer of alumina powder: when material falls from the discharge port of the upstream equipment into the inlet of the conveying device, a large amount of dust escapes from the connection point due to the impact of the drop and airflow disturbance, polluting the working environment and endangering the health of operators. While some existing devices use fixed dust covers to reduce dust, the dust cover structure is simple and cannot adapt to changes in the height or angle of the discharge port of different equipment, resulting in unstable sealing performance. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0023] Example: This example provides an alumina powder feeding and conveying device, see [link to example]. Figure 1-4 Specifically, it includes a screw conveyor body 1 and a dust cover 11 installed at the feed inlet of the screw conveyor body 1. The dust cover 11 is composed of a bottom frame 111, a corrugated pipe 112 and a cloth cover 113 that are fixedly connected in sequence. The bottom frame 111 is fixedly connected to the feed inlet of the screw conveyor body 1. An adjustment component 3 is installed on the outer wall of the screw conveyor body 1. The adjustment component 3 is connected to one end of the corrugated pipe 112. The adjustment component 3 is used to drive the dust cover 11 to extend and retract to adjust its height and angle.
[0024] In this embodiment, the base frame 111 serves as the base of the dust cover 11, achieving a rigid and sealed connection with the feed inlet of the screw conveyor body 1. The corrugated pipe 112 serves as the main pipe of the dust cover 11, and its bendable and stretchable characteristics are the core for adjusting the height and angle. The cloth cover 113 is usually made of flexible sealing material (such as waterproof cloth, felt, etc.). The cloth cover 113 has a frame composed of iron wire inside, which supports the cloth cover 113 into a frustum shape. The iron wire and the cloth cover 113 can quickly change shape, making it convenient for the cloth cover 113 to be fitted onto the discharge port of the upstream equipment. Alumina powder falls from the discharge port of the upstream equipment and enters the sealed channel formed by the cloth cover 113 and the corrugated pipe 112, falling directly into the screw conveyor, thereby effectively suppressing dust dispersion.
[0025] In the specific implementation process, such as Figure 1 and Figure 2 As shown, multiple connecting straps 2 are fixedly provided on the outer wall of the cloth cover 113, and ropes 21 are inserted into the connecting straps 2. By tightening the ropes 21, the connecting straps 2 can be tightened, thereby tightening the opening of the cloth cover 113, so that it can be tightly fitted onto the discharge port of the external equipment, forming a complete sealing system, which greatly enhances the dustproof effect.
[0026] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the adjustment component 3 includes a base 31 fixedly installed on the outer wall of the screw conveyor body 1. A fixed tube 32 is rotatably provided inside the base 31. A first moving tube 33 is slidably provided inside the fixed tube 32. A lubricating layer is added between the fixed tube 32 and the first moving tube 33. The sliding resistance increases with the number of uses without jamming. A second moving tube 34 is slidably provided inside the first moving tube 33. A screw 35 is threaded on the outer wall of the ends of the fixed tube 32 and the first moving tube 33. A bending member is provided at the end of the second moving tube 34.
[0027] In this embodiment, the base 31 is used to fix the entire adjustment assembly 3, providing a supporting foundation. The fixed tube 32, the first moving tube 33, and the second moving tube 34 form a three-stage telescopic structure, and the length is adjusted by sliding. The end of the second moving tube 34 is connected to the corrugated tube 112. The screw 35 locks the relative positions of the fixed tube 32 and the first moving tube 33, as well as the first moving tube 33 and the second moving tube 34, through threads to prevent slippage. During adjustment, the screw 35 is loosened, and the second moving tube 34 is manually stretched or compressed, causing the corrugated tube 112 to extend or retract; after adjusting to the appropriate length, the screw 35 is tightened to fix the position, ensuring that the corrugated tube 112 maintains the adjusted state to adapt to different discharge port heights.
[0028] In the specific implementation process, such as Figure 3 and Figure 4As shown, the bending component includes a rotating shaft 4 rotatably disposed at the end of the second moving tube 34. A rotating block 41 is fixedly disposed at one end of the rotating shaft 4, and a positioning ring 42 is disposed at the threaded part of the other end of the rotating shaft 4. A connecting component is disposed between the outer wall of the rotating block 41 and the bellows 112.
[0029] In this embodiment, the rotating shaft 4 allows the rotating block 41 to rotate around the shaft, thereby adjusting the angle. The rotating block 41 is a key component connected to the bellows 112, and its rotation adjusts the bending direction of the bellows 112. After the positioning ring 42 is tightened, it presses against the rotating shaft 4, fixing the angle of the rotating block 41 and preventing loosening after adjustment. When the angle of the bellows 112 needs to be adjusted, the positioning ring 42 is loosened, the rotating block 41 is rotated to the target angle (such as to accommodate an inclined discharge port), and then the positioning ring 42 is tightened to lock the rotating shaft 4, ensuring that the bellows 112 maintains its adjusted bending state and achieves a sealed connection.
[0030] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the connector includes a locking rod 5 fixedly mounted on the outer wall of the rotating block 41, a fixing frame 52 fixedly mounted on the outer wall of the end of the bellows 112, a locking block 51 fixedly mounted on the outer wall of the fixing frame 52, and the locking rod 5 inserted into the locking block 51.
[0031] In this embodiment, during installation, the locking rod 5 is inserted into the slot of the locking block 51 to achieve a rigid connection between the rotating block 41 and the bellows 112, so that the extension and angle adjustment force of the adjusting component 3 is transmitted to the bellows 112; during disassembly, the locking rod 5 can be pulled out directly to separate, which is convenient for maintenance or replacement of parts.
[0032] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the base 31 has multiple symmetrical slots 6, and a rod 61 is inserted into each slot 6, passing through the bottom edge of the fixing tube 32. The fixing tube 32 can rotate along the base 31 to adjust the angle of the dust cover 11. The fixing tube 32 is fixed in position by the rod 61 passing through the slot 6 and the bottom of the fixing tube 32.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
