Description

Technical Field

[0001] This utility model belongs to the field of unloading and dust removal technology, specifically referring to a dust removal device for unloading bauxite. Background Technology

[0002] In modern aluminum production, bauxite is the main ore raw material for aluminum refining, and its unloading process is the starting point of the entire production process and is crucial. However, the unloading of bauxite generates a large amount of dust. This dust, which floats in the air, not only seriously pollutes the surrounding atmospheric environment, but also spreads with air currents, affecting the quality of life of nearby residents and increasing the risk of respiratory diseases.

[0003] Most existing dust removal devices for bauxite unloading use a single filtration method, which is insufficient to handle dust of different particle sizes generated during bauxite unloading. Large dust particles easily clog the filter components, causing the equipment to malfunction, while fine particles often penetrate the filter layer, resulting in excessive pollutants in the exhaust gas. Moreover, the filter plates of traditional dust removal equipment are mostly fixed, making cleaning or replacement cumbersome and costly in terms of time and manpower, which seriously affects the continuity and production efficiency of bauxite unloading operations. Utility Model Content

[0004] To address the aforementioned problems of poor filtration efficiency and inconvenient maintenance of filter plates in dust removal devices, this utility model provides a dust removal device for unloading bauxite.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A dust removal device for unloading bauxite includes a dust removal box, an exhaust chamber connected to the side of the dust removal box, a fan installed in the exhaust chamber, a pull-out filter plate movably installed on the dust removal box for adsorbing dust after primary filtration, a limiting component provided on the side of the dust removal box for fixing the pull-out filter plate on the dust removal box, the pull-out filter plate dividing the dust removal box into an upper air chamber and a lower air chamber, a rectangular dust suction groove connected to the ground opened on the side of the dust removal box, a filter plate installed between the rectangular dust suction groove and the lower air chamber for preliminary filtration of dust and interception of some larger dust particles.

[0006] As a preferred technical solution of this utility model, the limiting component includes a rotating rod and an F-shaped support block. The rotating rod is fixedly mounted on the side of the dust collector body, and a torsion spring is sleeved on the rotating rod. One end of the F-shaped support block is rotatably mounted at the end of the rotating rod, and the other end of the F-shaped support block is connected to the end of the pull-out filter plate. The two ends of the torsion spring are respectively fixed on the side of the dust collector body and the inner side of the F-shaped support block.

[0007] As a preferred embodiment of this utility model, an L-shaped support rod is provided on the side of the dust collector, and the exhaust chamber is mounted on the L-shaped support rod.

[0008] As a preferred embodiment of this utility model, a push handle is provided on the side of the dust collection box.

[0009] As a preferred embodiment of this utility model, the bottom of the dust collection box is evenly provided with movable wheels equipped with brakes.

[0010] As a preferred embodiment of this utility model, the pull-out filter plate is an aramid cloth bag layer.

[0011] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0012] By combining filter plates, rectangular dust collection troughs, limiting components, and pull-out filter plates, efficient collection and graded filtration of dust generated during bauxite unloading is achieved. The rectangular dust collection troughs, under the action of a fan, create negative pressure suction, quickly drawing dust into the dust collector. The filter plates first intercept large dust particles, reducing the burden on subsequent filtration. The pull-out filter plates, using aramid fiber bags, further adsorb fine particles, ensuring purification efficiency. The limiting components facilitate the installation, fixing, and disassembly of the pull-out filter plates, making maintenance and replacement convenient. This enhances the practicality and stability of the dust collection device, effectively improving the working environment during bauxite unloading and reducing dust pollution.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, the present invention provides a dust removal device for unloading bauxite, including a dust removal box 1; a push handle 14 is provided on the side of the dust removal box 1 to facilitate the operator to push the dust removal box 1 to move; the bottom of the dust removal box 1 is evenly provided with moving wheels 15 with brakes, so that the entire dust removal device can be easily moved at the bauxite unloading site, and the position of the dust removal device can be flexibly adjusted according to different unloading positions to better target the dust source for dust collection. An exhaust chamber 2 is connected to the side of the dust removal box 1; an L-shaped support rod 13 is provided on the side of the dust removal box 1, and the exhaust chamber 2 is installed on the L-shaped support rod 13 to support the exhaust chamber 2. A fan 3 is installed in the exhaust chamber 2. When the fan 3 is working, it draws out the purified air in the dust removal box 1 and discharges it to the external environment through the exhaust chamber 2 to ensure the circulation of airflow in the dust removal box 1.

[0022] A pull-out filter plate 4 is movably installed on the dust collector 1 to adsorb the dust after primary filtration. The pull-out filter plate 4 is an aramid bag layer. When the airflow containing dust passes through the pull-out filter plate 4, the fine particles in the dust will be adsorbed by the aramid bag layer, thereby achieving further purification of the air and making the discharged gas meet certain environmental protection standards.

[0023] A limiting component 5 is provided on the side of the dust collector 1 to fix the pull-out filter plate 4 to the dust collector 1. The pull-out filter plate 4 divides the interior of the dust collector 1 into an upper air chamber 6 and a lower air chamber 7. A rectangular dust suction trough 8 connected to the ground is opened on the side of the dust collector 1. Under the action of the fan 3, a negative pressure environment is formed inside the dust collector 1. The dust generated during the unloading of bauxite is sucked into the lower air chamber 7 of the dust collector 1 from the rectangular dust suction trough 8 under the action of negative pressure suction. A filter plate 9 is installed between the rectangular dust suction trough 8 and the lower air chamber 7. The dust entering the lower air chamber 7 from the rectangular dust suction trough 8 will pass through the filter plate 9. The filter plate 9 can perform preliminary filtration of the dust, intercepting some larger dust particles and preventing them from directly entering the upper air chamber 6, thus reducing the filtration burden of the subsequent pull-out filter plate 4.

[0024] like Figure 2 and 3 As shown, the limiting assembly 5 includes a rotating rod 10 and an F-shaped support block 11. The rotating rod 10 is fixedly mounted on the side of the dust collector 1. A torsion spring 12 is sleeved on the rotating rod 10. One end of the F-shaped support block 11 is rotatably mounted on the end of the rotating rod 10, and the other end of the F-shaped support block 11 is connected to the end of the pull-out filter plate 4. The two ends of the torsion spring 12 are fixedly mounted on the side of the dust collector 1 and the inner side of the F-shaped support block 11, respectively. When the pull-out filter plate 4 is inserted into the dust collector 1, the F-shaped support block 11, under the action of the torsion spring 12, presses the pull-out filter plate 4 tightly onto the dust collector 1. This mechanism secures the pull-out filter plate 4, preventing it from shifting due to vibration during dust removal. When the pull-out filter plate 4 needs to be disassembled or replaced, rotating the F-type support block 11 causes the torsion spring 12 to deform significantly, storing elastic potential energy. This allows the pull-out filter plate 4 to be pulled out of the dust collector housing 1 for easy cleaning, replacement, and other maintenance operations. After the operation is completed, the pull-out filter plate 4 is reinserted, the F-type support block 11 is released, and the torsion spring 12 releases its elastic potential energy, allowing the F-type support block 11 to return to its initial position, thus securing the pull-out filter plate 4 again.

[0025] In practical use, when using the dust removal device for bauxite unloading, first use the push handle 14 on the side of the dust removal box 1 and the bottom moving wheels 15 to move it to the vicinity of the bauxite unloading point, so that the rectangular dust suction trough 8 is aligned with the dust generation source; then turn on the fan 3 in the exhaust chamber 2 to form a negative pressure in the box, so that the dust generated during unloading is sucked into the lower air chamber 7 from the rectangular dust suction trough 8, and the large dust particles are initially filtered by the filter plate 9 to reduce the burden of subsequent filtration; the dust-laden airflow continues to rise, and the fine particles are adsorbed by the pull-out filter plate 4 (aramid bag layer) to achieve deep purification. The purified air is discharged by the fan 3 through the exhaust chamber 2; when it is necessary to clean or replace the pull-out filter plate 4, rotate the F-type support block 11 to deform the torsion spring 12 and pull out the pull-out filter plate 4 for maintenance. After completion, reinsert the pull-out filter plate 4, loosen the F-type support block 11, and use the elastic reset of the torsion spring 12 to push the F-type support block 11 to fix the pull-out filter plate 4.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
