[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

It should be noted that, in the absence of conflict, the embodiments in this disclosure and the feature vectors in the embodiments can be arbitrarily combined with each other.
[0033] In the related technology, the pre-oxidation process is a crucial intermediate step in the preparation of carbon fiber. However, a large amount of silicon powder will be generated in this process. When using existing processing devices, the silicon powder accumulates in the production equipment, which can easily cause blockage of the device, resulting in the device not being able to work properly and causing safety hazards, such as overheating or pressure accumulation, which increases the risk to operators. At the same time, frequent blockages and improper maintenance will also extend the production cycle and reduce production efficiency and timeliness.
[0034] In order to solve the problems existing in the related art, the embodiment of the present disclosure provides a dust removal device for removing metal dust in exhaust gas, the dust removal device includes a box body and an ash suction component, the box body includes at least one dust removal chamber, the ash suction component is arranged in the dust removal chamber, the ash suction component includes a dust suction rod, a dust removal structure and a telescopic mechanism, the dust removal structure is sleeved on the outside of the dust suction rod, wherein the telescopic mechanism is connected to the dust suction rod and / or the dust removal structure, and is used to drive the dust removal structure and the dust suction rod to move relative to each other in the extension direction of the dust suction rod. In the present disclosure, the ash suction component is arranged in the dust removal chamber, the dust removal structure of the ash suction component is sleeved on the outside of the dust suction rod of the ash suction component, the telescopic mechanism of the ash suction component is connected to the dust suction rod and / or the dust removal structure, and is used to drive the dust removal structure and the dust suction rod to move relative to each other in the extension direction of the dust suction rod, and the dust suction structure scrapes off the dust adsorbed on the surface of the dust suction rod, so as to avoid the accumulation of dust on the surface of the dust suction rod, which leads to the decrease of the dust suction performance of the dust suction rod, and ensure the dust removal performance of the dust removal device.
[0035] In order to make the purpose, technical solution and beneficial effects of the embodiment of the present disclosure more clear, a dust removal device provided by the embodiment of the present disclosure is described in detail below in conjunction with the accompanying drawings. Figures 1 to 8 As shown, a dust removal device is shown for removing metal dust in exhaust gas, such as aluminum powder, silicon powder, tungsten powder, etc. These dusts may cause harm to operators during the production process. Therefore, a dust removal device is used to effectively process metal dust to avoid external environmental pollution.
[0036] like Figures 1 to 8 As shown, the dust removal device includes a box body 1 and a dust suction assembly 2. The shape and structure of the box body 1 can be adaptively set according to needs. The box body 1 includes at least one dust removal chamber 10. For example, the box body 1 can be provided with two dust removal chambers 10 (such as Figure 1 As shown), for example, the housing 1 may be provided with a dust removal chamber 10 (as shown Figure 5As shown), it can be adaptively set according to the required chamber size. The dust suction component 2 is arranged in the dust removal chamber 10. The dust suction component 2 is used to remove the exhaust gas or dust in the dust removal chamber 10. The dust suction component 2 includes a dust suction rod 21, a dust removal structure 22 and a telescopic mechanism 23. The metal dust is separated from the exhaust gas by suction and attached to the dust suction rod 21. The dust removal structure 22 is sleeved on the outside of the dust suction rod 21. During the cleaning process, the dust removal structure 22 can remove and collect the metal dust on the dust suction rod 21, and the dust removal structure 22 can be made of multi-layer filter screens or solid plate materials to ensure efficient dust removal effects. For example, the dust removal structure 22 may be composed of multiple layers of filter screens. During the dust removal process, when metal dust is adsorbed onto the dust collection rod 21, the dust removal structure 22 may scrape the metal dust onto the dust removal structure 22. The dust removal structure 22 with multiple layers of filter screens may filter and collect metal dust. For another example, the dust removal structure 22 may be a solid plate. The solid plate-shaped dust removal structure 22 may scrape the metal dust on the dust collection rod 21, scrape the metal dust to the bottom of the box 1 and collect it, thereby improving the dust removal effect.
[0037] The telescopic mechanism 23 is connected to the dust collecting rod 21 and / or the dust removing structure 22 to drive the dust removing structure 22 and the dust collecting rod 21 to extend in the direction of the dust collecting rod 21 (eg Figure 2 Relative motion in the z direction (as shown in FIG. Figure 2 As shown, the telescopic mechanism 23 is connected to the dust removal structure 22, and the dust removal structure 22 can be driven pneumatically or mechanically along the extension direction of the dust suction rod 21 (such as Figure 2 The dust collecting rod 21 is repeatedly moved in the z direction (as shown in the figure) so that the dust collecting structure 22 can cover the entire structure of the dust collecting rod 21, thereby improving the dust collecting efficiency and ensuring that metal dust can be effectively removed at different positions of the dust collecting rod 21. For another example, the telescopic mechanism 23 is connected to the dust collecting rod 21 and extends along the extension direction of the dust collecting rod 21 (as shown in the figure). Figure 2 The dust collecting rod 21 is driven to move in the z direction as shown in FIG. 2 , so that the dust removal structure 22 can collect the metal dust on the dust collecting rod 21 , thereby achieving a cleaning effect.
[0038] During the use of the dust removal device, the exhaust gas enters the dust removal chamber 10 in the box body 1, and the dust suction rod 21 absorbs the metal dust in the exhaust gas under the action of suction. Then the telescopic mechanism 23 drives the dust removal structure 22 to move repeatedly on the dust suction rod 21, ensuring that the entire surface of the dust suction rod 21 is evenly scraped by the dust removal structure 22, thereby further improving the dust removal effect and preventing dust from accumulating in the equipment.
[0039] In the present disclosure, the dust suction component is arranged in the dust removal chamber, the dust removal structure of the dust suction component is sleeved on the outer side of the dust suction rod of the dust suction component, and the telescopic mechanism of the dust suction component is connected to the dust suction rod and / or the dust removal structure to drive the dust removal structure and the dust suction rod to move relative to each other in the extension direction of the dust suction rod. The dust adsorbed on the surface of the dust suction rod is scraped off by the dust removal structure to avoid the accumulation of dust on the surface of the dust suction rod, which may lead to a decrease in the dust suction performance of the dust suction rod, thereby ensuring the dust removal performance of the dust removal device.
[0040] In some embodiments, the shape and structure of the dust removal structure 22 can be adaptively set as needed. In one example, Figure 1 and Figure 2 As shown, the dust removal structure 22 includes a plate-like body 221, which can be a square structure, and a plurality of through holes 222 arranged on the plate-like body 221. The dust suction rod 21 passes through the through holes 222, and there is a spacing of 2-5 mm between the inner diameter of the through hole 222 and the outer diameter of the dust suction rod 21, so that the dust removal structure 22 can move smoothly during operation. During the dust removal process, the plate-like body 221 can move around the dust suction rod 21 to ensure that the dust suction rod 21 can fully contact each through hole 222 on the plate-like body 221, and the plate-like body 221 is located between adjacent dust suction rods 21 and is connected to the telescopic mechanism 23 to perform the cleaning task of multiple dust suction rods 21 at the same time, so that the surface of each dust suction rod 21 can be scraped by the plate-like body 221, thereby improving the dust removal efficiency.
[0041] In some embodiments (not shown in the drawings), the inner diameter of the through hole is larger than the outer diameter of the vacuum stick, and an annular rubber plug is provided at the through hole, the inner ring of the annular rubber plug contacts the outer wall of the vacuum stick to scrape off the dust on the surface of the vacuum stick. In one example, the annular rubber plug can be a split rubber plug, which can be quickly replaced without removing the plate-like body from the vacuum stick.
[0042] In some embodiments, continue to refer to Figure 1 and Figure 8 The top surface of the plate-like body 221 is an inclined surface. The plate-like body 221 with an inclined surface is conducive to the sliding and collection of metal dust. For example, when the plate-like body 221 scrapes the metal dust attached to the dust suction rod 21, part of the metal dust may adhere to the surface of the plate-like body 221. The plate-like body 221 with an inclined surface facilitates the attached metal dust to slide down under the action of gravity, avoiding the accumulation of metal dust on the plate-like body 221, thereby reducing the cleaning frequency and improving the overall efficiency of the dust removal device. In some optional embodiments, for example, a vibration motor can be set inside or below the plate-like body, and the vibration of the motor drives the plate-like body to vibrate, ensuring that the metal dust can slide down.
[0043] In some embodiments, the extension direction of the dust suction rod 21 (eg Figure 2The z direction shown in FIG) and the height direction of the box 1 (as shown in FIG Figure 2 The angle between the dust collecting rod 21 and the dust collecting rod 21 is 0° to 30°, so as to ensure that the dust collecting rod 21 can cover a larger space range during the dust removal process, thereby improving the comprehensiveness of dust removal. Figure 1 and Figure 2 As shown, the extension direction of the dust suction rod 21 (as shown in Figure 2 The z direction shown in FIG) and the height direction of the box 1 (as shown in FIG Figure 2 There is an angle of 0° between the z direction shown in Figure 2 The z directions shown in FIG. 1 are parallel to each other, and a plurality of dust suction rods 21 are arranged in the dust removal chamber 10 , so that the dust removal structure 22 can quickly process the metal dust in the dust removal chamber 10 .
[0044] In another example (not shown in the drawings), since one side of the vacuum stick is an air inlet and the other side is an air suction port, the amount of dust adsorbed on both sides of the vacuum stick is different. Therefore, the placement angle of the vacuum stick can be adjusted according to actual conditions. For example, the extension direction of the vacuum stick and the height direction of the box can be set to an angle of 0°-30°, so that both sides of the vacuum stick can effectively adsorb dust to achieve a stronger dust removal effect. In some optional embodiments, the vacuum stick can also be connected to a motor, and the motor drives the vacuum stick to rotate, so that both sides of the vacuum stick can effectively adsorb dust.
[0045] In some embodiments, Figures 1 to 8 As shown, the dust removal device also includes an electrostatic emitter 3, which can generate static electricity within a certain range and has characteristics such as adsorption. The electrostatic emitter 3 is arranged outside the dust removal chamber 10 of the box body 1 and is electrically connected to the dust collection rod 21. The electrostatic emitter 3 can control the dust collection rods 21 in multiple dust removal chambers 10 at the same time. Multiple electrostatic emitters 3 can also be arranged and correspond to multiple dust removal chambers 10, so that each electrostatic emitter 3 can control the dust collection rod 21 in one dust removal chamber 10. In one example, continue to refer to Figure 1 The electrostatic emitter 3 is arranged on the top of the box body 1 and is connected to the dust collection rod 21 in the box body 1. Each electrostatic emitter 3 controls the corresponding dust collection rod 21. When dust removal is performed, turning on the electrostatic emitter 3 will generate static charge, and the static charge is transmitted to the inside of the dust removal chamber 10 of the box body 1 through the dust collection rod 21, thereby absorbing the metal dust in the dust removal chamber 10. After the required adsorption time, the dust absorption component 2 is used for scraping and cleaning, so as to achieve the dust removal effect through the action of electrostatics.
[0046] In some embodiments, continue to refer to Figures 1 to 8 The bottom of the box body 1 is provided with a funnel structure 4, the top of the funnel structure 4 is connected to the bottom of the dust removal chamber 10, and the shape of the funnel structure 4 can be a square structure, a trapezoidal structure, etc., and can be adaptively set as needed. In one example, as Figure 2 As shown, the funnel structure 4 is an inverted trapezoidal structure, which has a wide mouth and a narrow mouth. The inverted trapezoidal funnel structure 4 is not only conducive to the smooth collection and centralized discharge of metal dust or impurities, but also prevents blockage. The wide mouth of the inverted trapezoidal funnel structure 4 faces upward and is adapted to the bottom of the dust removal chamber 10, so that metal dust or impurities can easily enter the funnel structure 4 from the bottom of the dust removal chamber 10, and are discharged through the narrow mouth of the funnel structure 4 after being collected, thereby ensuring that the process of discharging metal dust or impurities is more efficient and smooth, reducing the frequency and difficulty of maintenance, and improving the working reliability and service life of the entire dust removal device.
[0047] In some embodiments, Figure 2 As shown, a dust collecting part 5 is installed at the bottom of the funnel structure 4. The dust collecting part 5 is used to collect and store metal dust or impurities discharged from the funnel structure 4 to prevent them from entering the air again. The dust collecting part 5 is connected to the bottom of the funnel structure 4 through a first valve 51. The first valve 51 can be a stop valve or a regulating valve. In one example, the dust collecting part 5 is connected to the bottom of the funnel structure 4 through a first valve 51. The first valve 51 can be a regulating valve. The regulating valve makes the connection between the funnel structure 4 and the dust collecting part 5 more sealed and firm. The discharge frequency and speed can also be controlled by adjusting the opening and closing of the valve. During the dust removal process, only the regulating valve needs to be opened, and the metal dust or impurities will flow from the funnel structure 4 to the dust collecting part 5, which is convenient for centralized treatment and also ensures the thoroughness and effectiveness of dust removal.
[0048] In some embodiments, Figures 1 to 4As shown, the box body 1 includes a plurality of independent dust removal chambers 10, each of which has an air inlet 101 and an air outlet 102, and the air inlet 101 and the air outlet 102 can ensure the flow and effective treatment of exhaust gas. The dust removal device includes an air inlet channel 6 and an air outlet channel 7, and the air inlet channel 6 includes an air inlet main duct 61 and a plurality of air inlet branch ducts 62 arranged in parallel. The air inlet main duct 61 is an exhaust gas conveying path and is connected to an exhaust gas generating device. When performing dust removal work, it can provide a stable gas flow. One end of the plurality of air inlet branch ducts 62 are connected to the air inlet main duct 61, so that the exhaust gas can enter and be distributed to the plurality of air inlet branch ducts 62 at the same time, thereby forming an efficient exhaust gas distribution process to quickly process the exhaust gas. The other ends of the air inlet branch ducts 62 are respectively connected to the air inlets 101 of the plurality of dust removal chambers 10, ensuring that each dust removal chamber 10 can receive sufficient gas flow to achieve efficient exhaust gas operation and treatment. The air outlet channel 7 includes an air outlet main duct 71 and a plurality of air outlet branch ducts 72 arranged in parallel. The air outlet main duct 71 is used to discharge the treated exhaust gas. One ends of the plurality of air outlet branch ducts 72 are connected to the air outlet main duct 71. The gases in the plurality of air outlet branch ducts 72 can be collected to the air outlet main duct 71 and centrally processed, thereby forming an efficient gas discharge process. The other ends of the air outlet branch ducts 72 are respectively connected to the air outlets 102 of the plurality of dust removal chambers 10, ensuring that the treated gas in each dust removal chamber 10 can be discharged smoothly, thereby achieving good ventilation and gas circulation of the entire system.
[0049] In one example, if Figures 1 to 4 As shown, the box body 1 includes two independent dust removal chambers 10, each of which is connected to the air inlet main duct 61 through the air inlet branch duct 62, and is connected to the air outlet main duct 71 through the air outlet branch duct 72. During the dust removal process, the exhaust gas flows into each air inlet branch duct through the air inlet main duct 61 to enter the corresponding dust removal chamber 10, and the electrostatic emitter 3 is turned on to control the dust collection rods 21 in the two boxes 1 to absorb the metal dust in the exhaust gas, and then clean and collect it. The exhaust gas in each dust removal chamber 10 is discharged through the exhaust main duct 71 through the air outlet branch duct 72, thereby completing the exhaust gas treatment work.
[0050] In some embodiments, Figures 1 to 7As shown, the air inlet main duct 61 and / or each air inlet branch duct 62 is provided with a second valve 8, and the second valve 8 is used to control the connection and disconnection of the duct, and / or the air outlet main duct 71 and / or each air outlet branch duct 72 is provided with a third valve 9, and the third valve 9 is used to control the connection and disconnection of the duct. For example, the air inlet main duct 61 is provided with a second valve 8, and the air outlet main duct 71 is provided with a third valve 9. When the dust removal work is performed, the second valve 8 can be opened to allow the exhaust gas to flow into the air inlet main duct 61 and the exhaust gas can be diverted to multiple dust removal chambers 10 through the air inlet branch duct 62, so that multiple dust removal chambers 10 can perform dust removal work at the same time. After the dust removal is completed, the third valve 9 is opened to collect the treated exhaust gas in the multiple dust removal chambers 10 to the air outlet main duct 71 through the air outlet branch duct 72 for centralized treatment, thereby improving the efficiency and quality of the simultaneous treatment of multiple dust removal chambers 10. For another example, a second valve 8 is provided on each air inlet branch duct 62, and a third valve 9 is provided on each air outlet branch duct 72. When dust removal is performed, the required exhaust gas capacity in different dust removal chambers 10 is adjusted, that is, the amount or speed of exhaust gas flowing into the dust removal chamber 10 from each air inlet branch duct is controlled by each second valve 8. After the dust removal is completed, adjustment is made according to the content of the treated exhaust gas in different dust removal chambers 10, that is, the speed or size of the exhaust gas flow in the corresponding air outlet branch duct 72 is controlled by each third valve 9, so as to ensure that the treated exhaust gas in each dust removal chamber 10 is smoothly discharged through the air outlet main duct 71, thereby improving the dust removal efficiency.
[0051] It should be noted that the connection positions and quantities of each air inlet branch duct 62 and air outlet branch duct 72 can be flexibly adjusted according to actual needs to adapt to dust removal tasks of different scales and types, thereby helping to improve the service life and dust removal efficiency of the overall device.
[0052] In some embodiments, Figures 1 to 5 As shown, the height of the air inlet 101 is not higher than the height of the air outlet 102, and the exhaust gas entering the dust removal chamber 10 can form an upward airflow path, thereby lifting the exhaust gas in the dust removal chamber 10 and preventing other impurities in the exhaust gas from sinking to the bottom of the dust removal chamber 10. Since the position of the air outlet 102 is higher than the air inlet 101, when the dust removal work is performed, the metal dust in the exhaust gas will be adsorbed onto the dust suction rod 21, and the remaining dust or impurities in the exhaust gas continue to be located at the top, which can be taken out through the air outlet, thereby improving the dust removal efficiency. Through the height difference between the air inlet 101 and the air outlet 102, the air flow path in each dust removal chamber 10 is optimized, thereby enhancing the dust removal effect.
[0053] The working principle of a dust removal device disclosed in the present invention:
[0054] like Figures 1 to 8As shown, first, the box body 1 is provided with appropriate dust removal chambers 10 according to the required number, the required dust removal chambers 10 are arranged in parallel, and the dust removal structure 22 is installed on the dust suction rod 21.
[0055] Next, the second valve 8 is controlled to transport the exhaust gas into the dust removal chamber 10 through the air inlet channel 6, so that the impurities in the exhaust gas in the dust removal chamber 10 are lifted and brought to the top, and at the same time, the electrostatic emitter 3 on the top of the box body 1 is turned on to adsorb the metal dust in the exhaust gas onto the dust collection rod 21.
[0056] After that, the electrostatic emitter 3 is turned off, and the plate-shaped body 221 on the dust removal structure 11 is used to extend along the extension direction of the dust suction rod 21 (such as Figure 2 The box body 1 is repeatedly moved in the z direction (as shown in the figure) to scrape and collect the metal dust in the exhaust gas. A funnel structure 4 is provided at the bottom of the box body 1, and the scraped metal dust can flow into the dust collecting part 5 through the funnel structure 4.
[0057] Finally, the third valve 9 is controlled to discharge the remaining impurities in the waste gas after adsorption through the air outlet 102, so that the waste gas in the box body 1 can be removed in time to achieve dust removal work, and at the same time, the dust removal device can be used continuously.
