The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application. It should be noted that unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. Without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Many specific details are set forth in the following description to facilitate a full understanding of the present application. The described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0044] In the embodiments of the present application, for the convenience of description rather than limiting the present application, the term "connection" used in the patent application specification and claims of the present application is not limited to physical or mechanical connection, whether direct or indirect. "Upper", "lower", "above", "below", "left", "right", etc. are only used to represent relative position relationships. When the absolute position of the object being described changes, the relative position relationship also changes accordingly.

[0045] Please refer to Figure 1 , an embodiment of the present application provides a feeding dust removal device 100, which can be applied to the feeding station of a roller hearth kiln to reduce the dust generated during the feeding process. The feeding dust removal device 100 includes a feeder 10, a dust-proof cover 20, and a dust collector 30. The feeder 10 passes through the dust-proof cover 20. The dust-proof cover 20 includes an inner layer 21 and an outer layer 22. The inner layer 21 and the outer layer 22 are spaced apart to form a dust suction cavity 23. The inner layer 21 is provided with a plurality of openings 211 therethrough, and each opening 211 communicates with the dust suction cavity 23. The dust collector 30 communicates with the dust suction cavity 23, and the dust collector 30 evacuates the air in the dust suction cavity 23 to collect the material dust in the dust suction cavity 23. It can be understood that in other embodiments, the above-mentioned feeding dust removal device 100 can be applied to other industrial equipment or stations involving the feeding of powdery materials 201 and requiring dust control, such as the feeding process of a glass melting furnace, the loading station of a metal powder sintering furnace, etc. In the feeding process of a glass melting furnace, similarly, the feeding of powdery materials 201 (such as quartz sand powder, etc.) is involved, and material dust is easily generated during the process. The present feeding dust removal device 100 can effectively reduce dust flying, improve the working environment and reduce the waste of materials 201. For the loading station of a metal powder sintering furnace, metal powder is easily scattered during feeding. By using the feeding dust removal device 100, through the synergistic effect of the dust suction cavity 23 of the dust-proof cover 20 and the dust collector 30, the material dust generated during the feeding process can be effectively collected, thereby improving production efficiency, protecting the health of operators, reducing equipment maintenance costs, and ensuring the normal operation of the equipment and the stability of product quality.

[0046] During specific use, first place the feeding dust removal device 100 above a crucible 200. When observing in the vertical direction, the dust shielding cover 20 covers the crucible 200. Then start the dust collector 30 to work, creating a negative pressure below the dust shielding cover 20 and inside the dust suction cavity 23. Feed the powdery material 201 into the crucible 200 through the feeder 10. During this process, due to the influence of gravity on the material 201, buoyancy in the air, electrostatic force between the particles of the material 201, etc., material dust is generated in the space below the dust shielding cover 20. Under the action of the negative pressure, this material dust enters the dust suction cavity 23 through multiple openings 211, and finally enters the dust collector 30 and is collected by the dust collector 30. In this way, the material dust generated during the feeding process can be effectively restricted within the area covered by the dust shielding cover 20, and is timely collected and processed through the dust suction cavity 23 and the dust collector 30, avoiding the diffusion of dust around the feeding station of the roller hearth kiln, greatly reducing the pollution of the production environment by the material dust, reducing the harm of the material dust to the health of the operators, preventing the dispersion and waste of the material 201, being beneficial to ensuring the normal operation of the equipment, reducing the maintenance frequency required due to the deposition of material dust on the equipment, and extending the service life of the equipment.

[0047] In some embodiments, the feeder 10 is generally funnel-shaped. The feeder 10 includes a first part 11 and a second part 12 connected to the first part 11. The first part 11 has a feed channel 111, and the second part 12 has a discharge channel 121. The feed channel 111 communicates with the discharge channel 121, and the cross-sectional width of the feed channel 111 is greater than the cross-sectional width of the discharge channel 121. That is, the wider feed channel 111 of the first part 11 facilitates receiving the material 201, while the narrower discharge channel 121 of the second part 12 extends to a position inside the dust shielding cover 20 close to the upper part of the crucible 200. The first part 11 is arranged on the side of the outer layer 22 away from the dust suction cavity 23, and the second part 12 penetrates through the dust shielding cover 20, so that the discharge channel 121 extends to a position inside the dust shielding cover 20 close to the upper part of the crucible 200, which is beneficial to accurately feeding the material 201 into the crucible 200.

[0048] In some other embodiments, the feeding dust removal device 100 further includes a valve with adjustable flow rate (not shown in the figure), and the valve is arranged in the discharge channel 121 to control the output speed of the material 201. In this way, it helps to accurately feed the material 201 according to the actual production requirements and can further optimize the control effect of material dust generation. On the one hand, in different production processes, there are different requirements for the feeding speed of the material 201. By adjusting the output speed of the material 201 with the valve, it can ensure that the material 201 is accurately and stably fed into the crucible 200 or other target containers according to the established production process and process parameters. For example, the production of some products may require a slower and uniform feeding speed of the material 201 to ensure the uniformity of product quality; while in some large-scale production scenarios, a faster feeding speed may be required to improve production efficiency, but at the same time, the accuracy of the material 201 feeding also needs to be ensured. On the other hand, the control of the output speed of the material 201 is also closely related to the amount of material dust generated. A slower and stable output speed of the material 201 usually reduces the impact and disturbance during the falling process of the material 201, thereby reducing the amount of material dust generated. When the working ability of the dust collector 30 is within a certain range, controlling the output speed of the material 201 helps to match the amount of material dust generated with the dust removal ability, avoiding the situation where excessive material dust is generated due to too fast feeding speed of the material 201, resulting in the dust collector being unable to collect dust in time and completely, and thus improving the effectiveness and reliability of the entire feeding dust removal device 100.

[0049] In still other embodiments, the feeding dust removal device 100 further includes an electrostatic eliminator (not shown in the figure), and the electrostatic eliminator is disposed at the end of the discharge passage 121. Thus, it is beneficial to reduce the agglomeration and adsorption phenomena of the material 201 particles due to electrostatic action, thereby improving the uniformity and accuracy of the material 201 feeding, and further reducing the generation of material dust. During the flow of the material 201 in the discharge passage 121, the material 201 may become electrostatically charged due to reasons such as friction. The electrostatically charged material 201 particles are prone to attracting and agglomerating with each other, which may cause blockage at the end of the discharge passage 121, affecting the normal feeding of the material 201, making the feeding uneven, and further affecting the normal progress of production. The setting of the electrostatic eliminator can neutralize the electrostatic charges carried by the material 201 particles, avoid particle agglomeration, and ensure that the material 201 can flow out from the end of the discharge passage 121 in a uniformly dispersed state and be put into a target container (such as the crucible 200). At the same time, the adsorption force generated by the electrostatic charge between the material 201 particles also affects the generation of material dust. When the material 201 particles are adsorbed together due to static electricity, their behavior during the falling process will change, and larger particle clusters may be formed. Such particle clusters are more likely to generate material dust when hitting during the fall. The electrostatic eliminator eliminates static electricity, enabling the material 201 particles to fall in a single or smaller particle group state, reducing the amount of material dust during the falling process, and helping to improve the dust removal effect of the entire feeding dust removal device 100.

[0050] In some embodiments, the dust shielding cover 20 is generally in a hollow bowl-shaped structure. Among them, the inner layer 21 includes a first top plate 212 and a first side plate 213, and the first side plate 213 surrounds one side of the first top plate 212 to form an inner dust collection space A. The outer layer 22 includes a second top plate 221 and a second side plate 222. The second top plate 221 surrounds one side of the second top plate 221. The second side plate 222 is disposed at an interval from the first side plate 213, and the second top plate 221 is disposed at an interval from the first top plate 212 to form the dust suction cavity 23. The second part 12 of the feeder 10 passes through the first top plate 212, the dust suction cavity 23, and the second top plate 221 and enters the inner dust collection space A. The first side plate 213 is obliquely connected to the first top plate 212, that is, the cross-sectional width of the first side plate 213 at the end far from the first top plate 212 is greater than the cross-sectional width of the first side plate 213 at the end close to the first top plate 212.

[0051] In some embodiments, a first opening 221a is formed through the second top plate 221. One end of the first opening 221a communicates with the dust suction chamber 23, and the other end communicates with the dust collector 30 through a pipeline 31. The first side plate 213 has a first distal end 213a away from the first top plate 212, and the second side plate 222 has a second distal end 222a away from the second top plate 221. A second opening 202 is formed between the first distal end 213a and the second distal end 222a, and the second opening 202 communicates with the dust suction chamber 23. When the dust collector 30 starts to work, a negative pressure is created at the second opening 202. Under the action of the negative pressure, the material dust at the second opening 202 enters the dust suction chamber 23. Then, together with the material dust entering through the plurality of openings 211, it enters the first opening 221a, and finally enters the dust collector 30 through the pipeline 31 and is collected by the dust collector 30. By providing the second opening 202 at the edge of the dust-proof cover 20, the material dust at the edge of the dust-proof cover 20 can be effectively collected. Since the edge of the dust-proof cover 20 may be an area where material dust is likely to escape, the provision of the second opening 202 can create a negative pressure attraction in this area, attracting the material dust that might otherwise disperse to the outside into the dust suction chamber 23, further improving the dust removal effect of the entire feeding dust removal device 100, ensuring that as much material dust as possible is collected and processed during the feeding process of the roller hearth kiln, and reducing the pollution to the surrounding environment.

[0052] In some embodiments, the first distal end 213a has a first surface 213b, and the second distal end 222a has a second surface 222b. The first surface 213b is flush with the second surface 222b, and the first surface 213b is arranged parallel to the first top plate 212. In this way, it helps to accurately determine the boundary of the second opening 202, making the structure of the second opening 202 more regular, and thus helping to form a stable and uniformly distributed negative pressure field at the second opening 202 when the dust collector 30 is working. The stable negative pressure area can more effectively attract the material dust at the edge of the dust-proof cover 20, ensuring that the material dust enters the dust suction chamber 23 more smoothly and efficiently, thereby further enhancing the collection effect of the entire feeding dust removal device 100 on the material dust and better meeting the dust removal requirements of the feeding station of the roller hearth kiln.

[0053] In some embodiments, the dust collector 30 includes a filter element (not labeled), a dust collection element (not labeled), and a power element (not labeled). The filter element is used to filter the air containing material dust, separating the material dust from the air flow. The filter can be composed of filter media such as filter bags and filter elements. When the air containing material dust passes through the filter element, the material dust is intercepted on the surface of the filter media, while the clean air can pass through. The dust collection element is used to collect the material dust intercepted by the filter element. The dust collection element can be a cavity with a certain capacity, and the filtered material dust accumulates in the dust collection element under the influence of gravity or other acting forces, facilitating subsequent cleaning. The power element provides power for the entire dust removal process. For example, it can be a device such as a fan. When the fan operates, it can form a negative pressure inside the dust collector 30 and in parts such as the dust suction cavity 23 connected thereto, prompting the dust-containing air to flow towards the dust collector 30 and ensuring the air flow circulation and the maintenance of the pressure difference in the entire dust removal process, thereby ensuring the continuous and effective operation of the feeding dust removal device 100.
