Description

Technical Field

[0001] This utility model relates to the field of carbon electrode production, specifically to a dust removal powder feeding device for carbon electrodes. Background Technology

[0002] Carbon electrodes are electrodes made of carbon materials and are widely used in metallurgy, chemical industry, electronics and other industrial fields. Carbon electrodes are conductive materials made from high-purity carbon materials (such as graphite or coke) through high-temperature processing, and their main component is carbon.

[0003] In the prior art, carbon electrodes are usually produced using carbon powder as the main raw material. The carbon powder is fed into a feeding device and introduced into the production equipment to produce carbon electrodes. A dust removal device is installed at the inlet of the feeding device to absorb the carbon powder dust generated during the feeding process.

[0004] However, the dust removal devices installed on the existing feeding devices are ineffective. When carbon powder is poured into the feed inlet of the feeding device, the generated carbon powder dust will fly out of the feed inlet before the dust removal device can absorb the generated dust. During this process, some dust is not absorbed by the dust removal device, resulting in carbon powder dust leakage, which has an adverse effect on the health of personnel. Utility Model Content

[0005] The purpose of this invention is to provide a dust-collecting powder feeding device for carbon electrodes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dust removal powder feeding device for carbon electrodes, comprising a feeding device body, wherein a dust removal powder mechanism body is installed inside the feeding device body, and the dust removal powder mechanism body includes an internal mounting mechanism, a motor, a rotating shaft, a fan, a rotating plate, a brush, a filter plate, and a lower guide structure.

[0007] Preferably, the lower guide structure has a funnel-shaped structure, the outer side of the lower guide structure is fixedly connected to the filter plate, and a positioning plate is fixedly connected to the filter plate.

[0008] Preferably, a brush is fixedly installed on the rotating plate, the brush is in contact with the upper surface of the filter plate, and the filter plate has an annular plate structure.

[0009] Preferably, a rotating shaft is fixedly connected to the rotating plate. The rotating shaft has a cylindrical structure, and a fan is fixedly connected to the rotating shaft. One end of the rotating shaft is fixedly connected to the drive shaft of the motor, and the motor is fixedly connected to the internal mounting mechanism.

[0010] Preferably, a lower mounting mechanism is installed at the lower end of the main body of the feeding device, and a dust removal mechanism body is installed inside the main body of the feeding device.

[0011] Preferably, the inner mounting mechanism has a cylindrical structure, and an upper guide mechanism is fixedly connected to the upper surface of the inner mounting mechanism. The upper guide mechanism has a hemispherical shape.

[0012] Preferably, the positioning plate has an "L" shaped plate structure, one end of which can be inserted into a positioning groove opened on the inner mounting mechanism, and an mounting plate is fixedly connected to the side of the inner mounting mechanism. The mounting plate has an "L" shaped plate structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention proposes a dust-collecting powder feeding device for carbon electrodes. A fan rotates, and under the constraint of a lower guide structure, it generates a downward airflow. According to Bernoulli's principle, where the wind speed is high, the air pressure is low. The resulting negative pressure causes the carbon dust within the feeding device to move downwards under the influence of the airflow. The carbon dust directly enters the carbon electrode production equipment through the discharge port on the lower mounting mechanism and does not escape from the inlet on the main body of the feeding device. This dust collection at the source of carbon dust generation is significantly more effective than installing a dust suction mechanism at the inlet of the main body of the feeding device. Better yet, it can effectively prevent carbon dust leakage. The filter plate can filter carbon dust in the air, preventing it from flying into the inner cavity of the inner mounting mechanism and damaging the motor. The brush fixedly installed on the rotating plate follows the rotation and repeatedly brushes the filter plate, causing the dust clogging the filter holes to fall off, improving the ventilation effect of the filter plate. The lower mounting mechanism and the main body of the dust removal mechanism can be disassembled from the main body of the feeding device. By unscrewing and removing the bolts on the positioning plate, the filter plate and the lower guide structure can be removed from the inner mounting mechanism, making it convenient for workers to disassemble the device for internal maintenance.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit 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.

[0024] Example 1

[0025] Please see Figures 1-6 This utility model provides a technical solution: a dust removal powder feeding device for carbon electrodes, including a feeding device body 1, and a dust removal powder mechanism body 2 installed inside the feeding device body 1. The dust removal powder mechanism body 2 includes an internal mounting mechanism 4, a motor 7, a rotating shaft 8, a fan 9, a rotating plate 10, a brush 11, a filter plate 13, and a lower guide structure 14.

[0026] In practical use, the main body 1 of the feeding device is fixedly installed with the lower mounting mechanism 3. The lower mounting mechanism 3 is installed on the production equipment. By starting the motor 7 in the main body 2 of the dust removal mechanism, the fan 9 is driven to rotate and generate airflow. Under the restriction of the lower guide structure 14, the airflow is blown downward. Where the wind speed is high, the air pressure is low, and a negative pressure is generated in the main body 1 of the feeding device. This drives the dust in the space between the main body 2 of the dust removal mechanism and the inner side of the main body 1 of the feeding device to move downward, instead of flying upward through the feed port on the main body 1 of the feeding device, thus avoiding the impact of dust on personnel.

[0027] Example 2

[0028] Based on Example 1, in order to enable the main body 1 of the feeding device to have a dust removal effect, a feeding device main body 1 is provided. A lower installation mechanism 3 is installed at the lower end of the feeding device main body 1. A dust removal powder mechanism main body 2 is installed inside the feeding device main body 1. The operator inverts the raw material onto the feeding port on the feeding device main body 1 and feeds the raw material into the carbon electrode production equipment through the feeding device main body 1.

[0029] The inner mounting mechanism 4 has a cylindrical structure. An upper guide mechanism 15 is fixedly connected to the upper surface of the inner mounting mechanism 4. The upper guide mechanism 15 has a hemispherical shape. The poured carbon powder slides down under the restriction of the upper guide mechanism 15. The lower guide structure 14 has a funnel-shaped structure. The outer side of the lower guide structure 14 is fixedly connected to the filter plate 13. A positioning plate 12 is fixedly connected to the filter plate 13. The carbon powder slides onto the inclined surface of the lower guide structure 14. Guided by the lower guide structure 14, the carbon powder continues to slide down until it falls into the carbon electrode production equipment through the discharge port on the lower mounting mechanism 3. A large amount of carbon dust is generated during this process. A rotating shaft 8 is fixedly connected to the rotating plate 10. The rotating shaft 8 has a cylindrical structure. A fan is fixedly connected to the rotating shaft 8. Fan 9, one end of the rotating shaft 8 is fixedly connected to the drive shaft of motor 7, and motor 7 is fixedly connected to the inner mounting mechanism 4. The motor 7 drives the fan 9 to rotate, generating airflow. Under the restriction of the lower guide structure 14, a downward airflow is generated. Where the wind speed is high, the air pressure is low. The negative pressure generated can drive the carbon dust in the main body 1 of the feeding device to move downward under the influence of the airflow. The carbon dust will directly enter the carbon electrode production equipment through the discharge port on the lower mounting mechanism 3. The generated carbon dust will not fly out from the inlet on the main body 1 of the feeding device. By removing dust at the source of carbon dust generation, the dust removal effect is better than installing a dust suction mechanism at the inlet of the main body 1 of the feeding device. It effectively avoids carbon dust leakage and improves the cleanliness of the production workshop.

[0030] A brush 11 is fixedly installed on the rotating plate 10. The brush 11 contacts the upper surface of the filter plate 13. The filter plate 13 has a ring-shaped structure and can be ventilated, serving as the upper ventilation of the dust removal mechanism 2. The filter plate 13 can filter carbon dust in the air, preventing carbon dust from flying into the inner cavity of the inner installation mechanism 4 and damaging the motor 7, thus improving the overall reliability of the device. The motor 7 is started to drive the rotating shaft 8 to rotate. The fan 9 on the rotating shaft 8 and the rotating plate 10 follow the rotation, driving the brush 11 fixedly installed on the rotating plate 10 to move. The brush 11 repeatedly brushes the filter plate 13, causing the dust blocking the filter holes on the filter plate 13 to fall off, thus improving the ventilation effect of the filter plate 13.

[0031] Example 3

[0032] Based on Embodiment 2, a positioning plate 12 is provided to facilitate subsequent maintenance by the staff. The positioning plate 12 has an "L"-shaped plate structure. One end of the positioning plate 12 can be inserted into the positioning groove 6 opened on the inner mounting mechanism 4. The inner mounting mechanism 4 is fixedly connected to the side of the mounting plate 5, which also has an "L"-shaped plate structure. The staff can remove the entire device from the production equipment, remove the lower mounting mechanism 3 from the main body 1 of the feeding device, and then loosen and remove the bolts on the mounting plate 5. This allows the dust removal mechanism main body 2 to be removed from the main body 1 of the feeding device. By loosening and removing the bolts on the positioning plate 12, the staff can remove the positioning plate 12 from the positioning groove 6 opened on the inner mounting mechanism 4, and remove the filter plate 13 and the lower guide structure 14 from the inner mounting mechanism 4. The structure is simple, making it easy for the staff to disassemble the device and facilitate subsequent maintenance, thus improving the reliability of the device.

[0033] In actual use, the fan 9 rotates and generates a downward airflow under the constraint of the lower guide structure 14. According to Bernoulli's principle, where the wind speed is high, the air pressure is low. The resulting negative pressure causes the carbon dust inside the main body 1 of the feeding device to move downward under the influence of the airflow. The carbon dust will directly enter the carbon electrode production equipment through the discharge port on the lower mounting mechanism 3 and will not fly out from the inlet on the main body 1 of the feeding device. Dust removal at the source of carbon dust generation is more effective than installing a dust suction mechanism at the inlet of the main body 1 of the feeding device, and can effectively prevent carbon dust leakage. The filter plate 13 can filter carbon dust in the air, preventing carbon dust from flying into the inner cavity of the inner mounting mechanism 4 and damaging the motor 7. The brush 11 fixedly installed on the rotating plate 10 follows the rotation and repeatedly brushes the filter plate 13, causing the dust clogging the filter holes to fall off and improving the ventilation effect of the filter plate 13. The lower mounting mechanism 3 and the dust removal mechanism body 2 can be disassembled from the feeding device body 1. The filter plate 13 and the lower guide structure 14 can be removed from the inner mounting mechanism 4 by unscrewing and removing the bolts on the positioning plate 12, making it convenient for the staff to disassemble the device for internal maintenance.
