[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention arranges a scraping assembly. When exhausting smoke, gas enters the smoke inlet pipe and flows to drive the filter plate to rotate. The rotation of the filter plate drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the reciprocating screw. The rotation of the reciprocating screw drives the sliding seat to move back and forth. The movement of the sliding seat drives the movement of the annular scraper, so that the annular scraper moves on the inner wall of the smoke inlet pipe. Since the outer wall of the annular scraper is slidingly fitted with the inner wall of the smoke inlet pipe, the impurities attached to the inner wall of the smoke inlet pipe are scraped off during the movement of the annular scraper to prevent the formation of a layer of impurities that is difficult to remove, which increases the resistance to smoke flow, thereby reducing the efficiency of the smoke exhaust system. Scraping away the impurities in time can ensure the efficiency of the smoke exhaust system.

[0021] 2. The present invention arranges a rotating assembly. When the scraping assembly is working, the movement of the sliding seat drives the movement of the second gear. The second gear meshes with the rack plate and rotates during the movement. The rotation of the second gear drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the fourth bevel gear. The rotation of the fourth bevel gear drives the rotation of the third bevel gear. The rotation of the third bevel gear drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the first gear. The rotation of the first gear drives the rotation of the annular gear. The rotation of the annular gear drives the rotation of the rotating ring. The rotation of the rotating ring drives the rotation of the mounting plate and the bristles, so that the bristles rotate when they move along the axis of the inner wall of the smoke inlet pipe. The rotating action increases the friction between the bristles and the inner wall of the smoke inlet pipe, thereby improving the efficiency of impurity removal, and can more effectively cover every corner of the inner wall of the smoke inlet pipe, reducing cleaning dead angles.

[0022] 3. The present invention arranges a knocking assembly. When the filter plate rotates, it drives the movement of the protrusion. When the end of the protrusion contacts the inner wall of the smoke inlet pipe, it slides into the filter plate under force. The end of the protrusion contacts the connecting rod to press it outward. The movement of the connecting rod drives the movement of the knocking plate, so that the knocking plate moves to the side away from the filter plate. At the same time, the connecting shaft slides in the filter plate. The movement of the connecting shaft drives the third spring to stretch and deform to store elastic potential energy. When one end of the protrusion is separated from the inner wall of the smoke inlet pipe, the elastic potential energy is released by the third spring to pull the connecting shaft to slide into the filter plate, so that the knocking plate moves to one side of the filter plate to produce a knocking effect on it, which helps to loosen and fall off impurities on the filter plate and keep the filtration unobstructed, thereby ensuring the normal operation of the smoke exhaust system and improving the smoke exhaust efficiency.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, in the embodiment of the present invention, a diffusion furnace for producing electroplated brass steel wire comprises a furnace body 1, a connecting pipe 2 is installed at the top of the furnace body 1, a smoke exhaust fan 4 is arranged on one side of the connecting pipe 2, the input end and the output end of the smoke exhaust fan 4 are respectively connected to a smoke inlet pipe 3 and a smoke exhaust pipe 5, and a filtering component and a scraping component are arranged inside the smoke inlet pipe 3;

[0034] The filter assembly includes a filter plate 6 disposed inside the smoke inlet pipe 3, a knocking assembly is disposed on the side wall of the filter plate 6, a plurality of filter plates 6 are evenly disposed in a ring array, and the plurality of filter plates 6 are fixedly mounted on the outer wall of a first rotating shaft 7, and the first rotating shaft 7 is rotatably mounted inside the smoke inlet pipe 3;

[0035] The scraping assembly includes an annular scraper 12 arranged inside the smoke inlet pipe 3, the top of the annular scraper 12 is fixedly connected to a sliding seat 11, the inner wall of the sliding seat 11 is threadedly connected to a reciprocating screw rod 10, one end of the reciprocating screw rod 10 is fixedly connected to a second bevel gear 9, the bottom end of the second bevel gear 9 is meshedly connected to a first bevel gear 8, and the first bevel gear 8 is fixedly installed on the top of the first rotating shaft 7.

[0036] When the diffusion furnace is working, the smoke exhaust fan 4 is controlled to start and connected to the connecting pipe 2 through the smoke inlet pipe 3 to exhaust the smoke and waste gas inside the furnace body 1 to keep the furnace environment clean;

[0037] During smoke exhaust, the gas flows into the smoke inlet pipe 3 and drives the filter plate 6 to rotate. The rotation of the filter plate 6 drives the rotation of the first rotating shaft 7. The rotation of the first rotating shaft 7 drives the rotation of the first bevel gear 8. The rotation of the first bevel gear 8 drives the rotation of the second bevel gear 9. The rotation of the second bevel gear 9 drives the rotation of the reciprocating screw 10. The rotation of the reciprocating screw 10 drives the sliding seat 11 to move back and forth. The movement of the sliding seat 11 drives the movement of the annular scraper 12, so that the annular scraper 12 moves on the inner wall of the smoke inlet pipe 3. Since the outer wall of the annular scraper 12 is slidingly fitted with the inner wall of the smoke inlet pipe 3, the impurities attached to the inner wall of the smoke inlet pipe 3 are scraped off during the movement of the annular scraper 12 to prevent the formation of a layer of impurities that are difficult to remove, increase the resistance to smoke flow, and thus reduce the efficiency of the smoke exhaust system. Scraping away impurities in time can ensure the efficiency of the smoke exhaust system.

[0038] like Figure 2 , Figure 3 and Figure 7 As shown, a rotating ring 13 is installed on one side of the annular scraper 12 through a rotating assembly, and a mounting plate 14 is installed on the outer wall of the rotating ring 13. The mounting plates 14 are evenly distributed in an annular array, and bristles 15 are fixedly installed on the outer wall of each mounting plate 14.

[0039] The movement of the annular scraper 12 drives the movement of the rotating ring 13, the movement of the rotating ring 13 drives the movement of the mounting plate 14, the movement of the mounting plate 14 drives the movement of the brush 15, the brush 15 contacts the inner wall of the smoke inlet pipe 3 during the movement, and the impurities attached to the inner wall of the smoke inlet pipe 3 are removed by the friction and scraping effect of the brush 15, so as to prevent the accumulation of impurities on the inner wall of the smoke inlet pipe 3, which may cause corrosion or wear to the pipe material. By scraping off these impurities, their damage to the pipe material can be reduced, thereby extending the service life of the pipe;

[0040] The bristles 15 are arranged on the leeward side;

[0041] When the bristles 15 brush off the impurities, the annular scraper 12 scrapes them away. The combined use of the two can better clean the impurities attached to the inner wall of the smoke inlet pipe 3.

[0042] like Figure 3 and Figure 4 As shown, the rotating assembly includes an annular gear 16 fixedly connected to one side of the rotating ring 13, the annular gear 16 is embedded in the inside of the annular scraper 12, the top of the annular gear 16 is meshedly connected with the first gear 17, the inner wall of the first gear 17 is fixedly mounted with a second rotating shaft 18, one end of the second rotating shaft 18 is fixedly mounted with a third bevel gear 19, the top of the third bevel gear 19 is meshedly connected with a fourth bevel gear 20, the top of the fourth bevel gear 20 is fixedly mounted with a third rotating shaft 21, the top of the third rotating shaft 21 is fixedly mounted with a second gear 22, one side of the second gear 22 is meshedly connected with a rack plate 23, and the rack plate 23 is fixedly mounted on the inner wall of the smoke inlet pipe 3.

[0043] When the scraping assembly is working, the movement of the sliding seat 11 drives the movement of the second gear 22. The second gear 22 meshes with the rack plate 23 and rotates during the movement. The rotation of the second gear 22 drives the rotation of the third rotating shaft 21. The rotation of the third rotating shaft 21 drives the rotation of the fourth bevel gear 20. The rotation of the fourth bevel gear 20 drives the rotation of the third bevel gear 19. The rotation of the third bevel gear 19 drives the rotation of the second rotating shaft 18. The rotation of the second rotating shaft 18 drives the rotation of the first gear 17. The rotation of the first gear 17 drives the rotation of the ring gear 16. The rotation of the ring gear 16 drives the rotation of the rotating ring 13. The rotation of the rotating ring 13 drives the rotation of the mounting plate 14 and the bristles 15, so that the bristles 15 rotate when moving along the axis of the inner wall of the smoke inlet pipe 3. The rotating action increases the friction between the bristles 15 and the inner wall of the smoke inlet pipe 3, thereby improving the efficiency of impurity removal, and can more effectively cover every corner of the inner wall of the smoke inlet pipe 3, reducing cleaning dead angles.

[0044] like Figures 2 to 4 As shown, the sliding seat 11 is arranged on the outer wall of the rack plate 23 , and the sliding seat 11 and the rack plate 23 are slidably connected.

[0045] like Figure 7 and Figure 8 As shown, a slider 24 is fixedly mounted on the bottom end of the mounting plate 14 , and the slider 24 is slidably mounted on the inner wall of the rotating ring 13 , and a first spring 25 is arranged between the slider 24 and the rotating ring 13 .

[0046] When the mounting plate 14 moves or rotates with the rotating ring 13, the elasticity of the first spring 25 can make the slider 24 slide a certain distance in the inner wall of the rotating ring 13, which helps the bristles 15 to maintain good elasticity and toughness during long-term use, and is less likely to break or deform, thereby improving durability and reliability.

[0047] like Figure 8 As shown, the first springs 25 are arranged on both sides of the slider 24 .

[0048] like Figure 7 and Figure 8 As shown, the mounting plate 14 is slidably mounted on the top end of the rotating ring 13 .

[0049] The inner wall of the rotating ring 13 is provided with a slide groove for the sliding block 24 to slide, and the mounting plate 14 is located above the slide groove;

[0050] When the slider 24 slides in the slide groove on the inner wall of the rotating ring 13 , it is blocked and protected by the mounting plate 14 .

[0051] like Figure 7 As shown, a ventilation cavity 26 is formed on the inner wall of the annular scraper 12 , and the ventilation cavity 26 is arranged on one side of the bristles 15 .

[0052] During the operation of the device, smoke and dust gas is blown toward one side of the bristles 15 through the ventilation cavity 26, so that the bristles 15 are in contact with the gas during the rotation of the rotating ring 13, which helps to blow away the impurities on the inner wall of the bristles 15 and under the brush.

[0053] like Figure 5 and Figure 6 As shown, the knocking assembly includes a knocking plate 27 disposed on one side of the filter plate 6, a connecting shaft 31 is fixedly connected to the side wall of the knocking plate 27, the connecting shaft 31 is embedded in the inside of the filter plate 6, and a third spring 32 is disposed between the connecting shaft 31 and the filter plate 6;

[0054] The side walls at both ends of the knocking plate 27 are fixedly connected with connecting rods 28 , and the two connecting rods 28 are slidably installed inside the filter plate 6 , and a protrusion 29 is provided on one side of one of the connecting rods 28 .

[0055] One side of one of the connecting rods 28 close to the protrusion 29 is arranged in an inclined shape;

[0056] When the filter plate 6 rotates, the projection 29 is driven to move. When the end of the projection 29 contacts the inner wall of the smoke inlet pipe 3, it is forced to slide into the filter plate 6. The end of the projection 29 contacts the connecting rod 28 to press it outward. The movement of the connecting rod 28 drives the knocking plate 27 to move away from the filter plate 6. At the same time, the connecting shaft 31 slides in the filter plate 6. The movement of the connecting shaft 31 drives the third spring 32 to stretch and deform to store elastic potential energy.

[0057] When one end of the protrusion 29 is separated from the inner wall of the smoke inlet pipe 3, the third spring 32 releases elastic potential energy to pull the connecting shaft 31 into the filter plate 6, so that the knocking plate 27 moves to one side of the filter plate 6 to produce a knocking effect on it, which helps to loosen and fall off impurities on the filter plate 6, keeping the filtration unobstructed, thereby ensuring the normal operation of the smoke exhaust system and improving the smoke exhaust efficiency.

[0058] like Figure 6 As shown, the protrusion 29 is slidably installed inside the filter plate 6, and a second spring 30 is installed between the filter plate 6 and the protrusion 29.

[0059] When the protrusion 29 contacts the inner wall of the smoke inlet pipe 3 and slides into the filter plate 6, the second spring 30 is deformed by force to store elastic potential energy;

[0060] When the protrusion 29 is separated from the inner wall of the smoke inlet pipe 3 , the second spring 30 releases the elastic potential energy to reset, which helps the knocking plate 27 to knock the filter plate 6 back and forth.

[0061] Working principle and usage process:

[0062] When the diffusion furnace is working, the smoke exhaust fan 4 is controlled to start and connected to the connecting pipe 2 through the smoke inlet pipe 3 to exhaust the smoke and waste gas inside the furnace body 1 to keep the furnace environment clean;

[0063] When exhausting smoke, the gas flows into the smoke inlet pipe 3 to drive the filter plate 6 to rotate, the rotation of the filter plate 6 drives the rotation of the first rotating shaft 7, the rotation of the first rotating shaft 7 drives the rotation of the first bevel gear 8, the rotation of the first bevel gear 8 drives the rotation of the second bevel gear 9, the rotation of the second bevel gear 9 drives the rotation of the reciprocating screw 10, the rotation of the reciprocating screw 10 drives the sliding seat 11 to move back and forth, the movement of the sliding seat 11 drives the movement of the annular scraper 12, so that the annular scraper 12 moves in the inner wall of the smoke inlet pipe 3 to scrape off impurities attached to the inner wall of the smoke inlet pipe 3;

[0064] At the same time, the movement of the annular scraper 12 drives the movement of the rotating ring 13, the movement of the rotating ring 13 drives the movement of the mounting plate 14, and the movement of the mounting plate 14 drives the movement of the bristles 15. The bristles 15 contact the inner wall of the smoke inlet pipe 3 during the movement, and the impurities attached to the inner wall of the smoke inlet pipe 3 are removed by the friction and scraping effect of the bristles 15.

[0065] At the same time, the movement of the sliding seat 11 drives the movement of the second gear 22, and the second gear 22 meshes with the rack plate 23 and rotates during the movement. The rotation of the second gear 22 drives the rotation of the third rotating shaft 21, and the rotation of the third rotating shaft 21 drives the rotation of the fourth bevel gear 20. The rotation of the fourth bevel gear 20 drives the rotation of the third bevel gear 19. The rotation of the third bevel gear 19 drives the rotation of the second rotating shaft 18. The rotation of the second rotating shaft 18 drives the rotation of the first gear 17. The rotation of the first gear 17 drives the rotation of the ring gear 16. The rotation of the ring gear 16 drives the rotation of the rotating ring 13. The rotation of the rotating ring 13 drives the rotation of the mounting plate 14 and the bristles 15, so that the bristles 15 rotate when moving along the axis of the inner wall of the smoke inlet pipe 3, thereby increasing the friction between the bristles 15 and the inner wall of the smoke inlet pipe 3.

[0066] When the filter plate 6 rotates, the projection 29 is driven to move. When the end of the projection 29 contacts the inner wall of the smoke inlet pipe 3, it is forced to slide into the filter plate 6. The end of the projection 29 contacts the connecting rod 28 to press it outward. The movement of the connecting rod 28 drives the knocking plate 27 to move to the side away from the filter plate 6. At the same time, the connecting shaft 31 slides in the filter plate 6. The movement of the connecting shaft 31 drives the third spring 32 to stretch and deform to store elastic potential energy. When one end of the projection 29 is separated from the inner wall of the smoke inlet pipe 3, the elastic potential energy is released by the third spring 32 to pull the connecting shaft 31 into the filter plate 6, so that the knocking plate 27 moves to one side of the filter plate 6 to produce a knocking effect on it, which helps to loosen and fall off the impurities on the filter plate 6 and keep the filtration smooth.

[0067] When the diffusion furnace stops working, the smoke exhaust fan 4 needs to continue working for a period of time to exhaust smoke.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
