Description

Technical Field

[0001] This invention relates to the field of fastener manufacturing, and more specifically, to a fume purification device for fastener manufacturing. Background Technology

[0002] During the manufacturing process of fasteners (such as bolts, nuts, and screws), especially in processes like heat treatment, forging, welding, and spraying, industrial fumes containing oil mist, dust, and harmful gases (such as volatile organic compounds and nitrogen oxides) are often generated. If these pollutants are emitted directly without effective treatment, they will not only severely pollute the workshop environment and endanger the health of operators, but may also damage the atmospheric environment. Therefore, equipping fastener production lines with efficient and reliable fume purification equipment is crucial.

[0003] Traditional spray or wet scrubbing equipment often relies on static diffusion or simple convection for gas-liquid contact, resulting in insufficient contact and long reaction times. This leads to limited purification efficiency for some harmful substances, making it difficult to meet increasingly stringent emission standards. Furthermore, in equipment using mechanical filtration methods such as filters and plates, the pores of the filter media (such as filter plates) are easily and quickly clogged when treating high-concentration, oily, or sticky particulate matter fumes. This not only drastically increases system resistance and affects ventilation, but also causes a rapid decline in equipment purification efficiency. Frequent shutdowns are required for manual cleaning or filter replacement, severely impacting production continuity and increasing maintenance costs and manpower burden.

[0004] Therefore, a fume purification device for fastener production is proposed. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a fume purification device for fastener production, which can improve the contact effect between harmful gases and treatment liquids and accelerate the reaction speed.

A first spring is fixedly connected to the upper end of the moving block, and the upper end of the first spring is fixedly connected to the inner wall of the upper end of the circular shell. A protrusion is slidably connected to the inner wall of the moving block, and a second spring is fixedly connected to one side of the protrusion. A support rod is fixedly connected to the inner wall of the lower end of the conical shell, and a support plate is fixedly connected to the upper end of the multiple support rods.

[0008] Preferably, a limiting rod is fixedly connected to the upper inner wall of the conical shell, and the wall of the limiting rod is slidably connected to both sides of the inner side of the circular block.

[0009] Preferably, the interior of the support plate is slidably connected to the wall of the rotating rod, and a third spring is sleeved on the wall of the rotating rod, with the upper end of the third spring fixedly connected to the lower end of the support plate.

[0010] Preferably, blades are fixedly connected to both sides of the rod wall of the rotating rod.

[0011] Preferably, a horizontal block is fixedly connected to the upper end of the blade, a cleaning block is slidably connected to the upper end of the horizontal block, and a fourth spring is fixedly connected to the lower end of the cleaning block.

[0012] Preferably, a load-bearing rod is fixedly connected to the upper end of the inner wall of the processing shell, and the lower end of the load-bearing rod is rotatably connected to the upper end of the rotating rod.

[0013] Preferably, a reciprocating screw is fixedly connected to the lower end of the load-bearing rod. The upper end of the lower end of the reciprocating screw is rotatably connected to the interior of the rotating rod. A rectangular block is meshed with the wall of the reciprocating screw. A rectangular groove is formed inside the wall of the rotating rod. A gear is rotatably connected inside the rectangular groove. Gears are meshed with toothed rods on both sides of the gear. The upper end of the toothed rod on the left is fixedly connected to the lower end of the rectangular block. A vertical rod is fixedly connected to the inner wall of the rectangular groove. The wall of the vertical rod is slidably connected to the interior of the toothed rod on the right. A horizontal bar is provided on the opposite side of both toothed rods. A moving rod is slidably connected inside the horizontal bar. A sixth spring is sleeved on the upper end of the wall of the moving rod. A top block is fixedly connected to the lower end of the moving rod.

[0014] Preferably, a support block is fixedly connected to each of the two opposing sides of the rack, a fifth spring is fixedly connected inside the support block, one side of the fifth spring is fixedly connected to the crossbar, a sliding groove is provided at the upper and lower positions of the support block, a slider is slidably connected inside the sliding groove, a round rod is fixedly connected at the upper and lower positions of the crossbar, the wall of the round rod is rotatably connected to the inside of the slider, and a return spring is fixedly connected between the round rod and the slider.

[0015] Preferably, a drain pipe is fixedly connected to the lower end of the processing shell.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention uses airflow to drive the blades to rotate the rotating rod, and then uses structures such as reciprocating grooves, circular blocks and moving blocks to make the conical shell vibrate periodically. This vibration can effectively bounce gas molecules in the purification chamber, increase the contact area and contact effect between the gas and the treatment liquid sprayed from the nozzle, and accelerate the chemical reaction rate between the treatment liquid and harmful substances in the gas, thereby significantly improving the purification efficiency of the smoke.

[0017] (2) The rotation of this rotating rod is driven by a reciprocating screw, rectangular block, rack and pinion, and gears to make the crossbar with the top block reciprocate up and down; on the other hand, the rotating rod also drives the crossbar to rotate. This allows the top block to align with and insert into different filter holes of the filter plate during rotation, pushing the impurities clogging the filter holes downwards. This design realizes fully automatic and uninterrupted cleaning of the core filter element during the purification process, effectively preventing filter plate clogging and ensuring long-term stable operation and continuous filtration effect of the equipment.

[0018] (3) When the top block is stuck in the filter hole, the continued movement of the rack will cause the crossbar to shift and rotate relative to the support block, thereby storing elastic potential energy. Once the top block is dislodged from the filter hole, the stored energy will quickly reset the crossbar. This mechanism avoids rigid interference between the cleaning components and the filter plate, ensuring that the rotation of the entire transmission system is not obstructed while cleaning efficiently, greatly improving the operational reliability and service life of the equipment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 9 A fume purification device for fastener production includes a housing 1, a treatment shell 6 fixedly connected inside the housing 1, an air inlet pipe 3 fixedly connected to the lower end of the treatment shell 6, through which gas containing harmful substances is introduced into the interior of the treatment shell 6, a driving fan device is connected to the outside of the air inlet pipe 3, an exhaust pipe 2 fixedly connected to the upper end of the treatment shell 6, the exhaust pipe 2 is used to discharge the treated gas, and a fume treatment mechanism is provided inside the treatment shell 6. The smoke treatment mechanism includes a liquid pipe 5 fixedly connected to the left side of the treatment housing 6, which is used to introduce treatment liquid into the interior of the treatment housing 6. A filter plate 7 is fixedly connected to the lower end of the inner wall of the treatment housing 6. A rotating rod 9 is rotatably connected inside the air inlet pipe 3. Blades 10 are evenly arranged on the lower end of the rod wall of the rotating rod 9. The blades 10 are located inside the air inlet pipe 3, so that when the gas flows, the gas has a certain blowing effect on the blades 10, which causes the blades 10 to move and drive the rotating rod 9 to rotate. A conical shell 8 is rotatably connected to the upper end of the rotating rod 9, and the rotating rod 9 can rotate relative to the conical shell 8. The left side of the conical shell 8 is fixedly connected to the right side of the liquid pipe 5. A nozzle 41 is evenly fixedly connected to the lower end of the interior of the conical shell 8. The nozzle 41 is used to atomize the liquid. A liquid shell 40 is fixedly connected to the inner wall of the conical shell 8, and the liquid shell 40 communicates with the nozzle 41. The upper end of the rod wall of the rotating rod 9 is open. A reciprocating groove 31 is provided, and a circular block 33 is engaged with the outer side of the reciprocating groove 31. The rotation of the rotating rod 9 causes the reciprocating groove 31 to rotate, thereby causing the circular block 33 to move up and down continuously. A circular shell 36 is fixedly connected to the inner wall of the upper end of the conical shell 8. A moving block 34 is slidably connected to the inner wall of the circular shell 36. A first spring 37 is fixedly connected to the upper end of the moving block 34. The upper end of the first spring 37 is fixedly connected to the inner wall of the upper end of the circular shell 36. The first spring 37 has a downward pushing force on the moving block 34. A protrusion 39 is evenly slidably connected to the inner wall of the moving block 34. The protrusion 39 can move into the interior of the moving block 34. A second spring 38 is fixedly connected to one side of the protrusion 39. The second spring 38 has a certain pushing force on the protrusion 39. A support rod 35 is fixedly connected to the inner wall of the lower end of the conical shell 8. A support plate 43 is fixedly connected to the upper end of the multiple support rods 35. During operation, gas is introduced into the processing housing 6 through the intake pipe 3. This gas exerts a certain blowing force on the blades 10, causing them to move. The blades 10 cause the rotating rod 9 to rotate, which in turn drives the reciprocating groove 31 to rotate. The rotation of the reciprocating groove 31 causes the circular block 33 to move up and down continuously. When the circular block 33 moves upward, it contacts the protrusion 39, causing the protrusion 39 to drive the moving block 34 upward. The upward movement of the moving block 34 compresses the first spring 37. When the elastic force of the first spring 37 reaches a certain level, the circular block 33 continues to move upward, causing it to misalign with the protrusion 39. At this point, the moving block 34, under the action of the first spring 37... The cone-shaped shell 8 moves downwards rapidly, impacting the upper end of the support plate 43 and causing it to vibrate. The support rod 35 causes the lower end of the cone-shaped shell 8 to vibrate. As the circular block 33 moves downwards, the moving block 34 is limited by the support plate 43, allowing the circular block 33 to smoothly pass over the protrusion 39 and reset. This improves the contact between the gas and the treatment liquid. The vibration of the cone-shaped shell 8 enhances the rebound effect of gas molecules, thus improving the contact between the treatment liquid and the gas. Simultaneously, the vibration accelerates the reaction speed between the treatment liquid and the gas, thereby improving the removal of harmful substances from the gas.

[0023] like Figure 8 and Figure 9 As shown, a limiting rod 32 is fixedly connected to the upper inner wall of the conical shell 8. The rod wall of the limiting rod 32 is slidably connected to both sides of the inner side of the circular block 33. The limiting rod 32 enables the circular block 33 to move stably up and down.

[0024] like Figure 8 As shown, the interior of the support plate 43 is slidably connected to the wall of the rotating rod 9. The wall of the rotating rod 9 is fitted with a third spring 42. The upper end of the third spring 42 is fixedly connected to the lower end of the support plate 43. Through the third spring 42 and the slidable connection between the rotating rod 9 and the support plate 43, the impact force of the moving block 34 on the support plate 43 can be better transmitted to the lower end of the conical shell 8, thereby improving the vibration effect.

[0025] like Figure 3 and Figure 5 As shown, blades 12 are fixedly connected to both sides of the rotating rod 9. A horizontal block 13 is fixedly connected to the upper end of the blade 12. A cleaning block 14 is slidably connected to the upper end of the horizontal block 13. A fourth spring 15 is fixedly connected to the lower end of the cleaning block 14. The rotation of the rotating rod 9 drives the blades 12 to rotate, thereby sweeping the gas entering the processing shell 6. This allows the gas to pass through the filter plate 7 evenly, thereby improving the efficiency of the filter plate 7. Through the supporting force of the fourth spring 15 on the cleaning block 14, the upper end of the cleaning block 14 is in contact with the lower end of the filter plate 7. The movement of the blades 12 drives the horizontal block 13 to move, thereby moving the cleaning block 14 to scrape away harmful substances at the lower end of the filter plate 7, ensuring the filtration effect of the filter plate 7.

[0026] like Figure 2 As shown, a load-bearing rod 11 is fixedly connected to the upper end of the inner wall of the processing shell 6. The lower end of the load-bearing rod 11 is rotatably connected to the upper end of the rotating rod 9, so that the rotating rod 9 can rotate stably.

[0027] like Figure 3-7As shown, a reciprocating screw 18 is fixedly connected to the lower end of the load-bearing rod 11. Under the action of the load-bearing rod 11, the reciprocating screw 18 is in a stationary state. The lower end and upper end of the reciprocating screw 18 are rotatably connected to the inside of the rotating rod 9. A rectangular block 17 is meshed with the wall of the reciprocating screw 18. The rotation of the rotating rod 9 drives the rectangular block 17 to rotate, and thus rotates relative to the reciprocating screw 18. This allows the rectangular block 17 to move up and down inside the rotating rod 9. A rectangular groove 22 is opened inside the wall of the rotating rod 9. A gear 20 is rotatably connected inside the rectangular groove 22. Both sides of the gear 20 are meshed with toothed rods 19. The toothed rods 19 can move up and down in the rectangular groove. The internal structure of 22 moves up and down. The upper end of the left toothed rod 19 is fixedly connected to the lower end of the rectangular block 17. The rectangular block 17 drives the left toothed rod 19 to move. Through the gear 20, the right toothed rod 19 moves up and down. The inner wall of the rectangular groove 22 is fixedly connected to a vertical rod 21. The rod wall of the vertical rod 21 is slidably connected to the inside of the right toothed rod 19. Both toothed rods 19 are provided with horizontal rods 16 on opposite sides. The inside of the horizontal rods 16 is evenly connected to a moving rod 29. The upper end of the rod wall of the moving rod 29 is fitted with a sixth spring 30. The sixth spring 30 has a downward pushing force on the vertical rod 21. The lower end of the moving rod 29 is fixedly connected to a top block 44. The rotation of the rotating rod 9 drives the rectangular block 17 to rotate. Under the action of the reciprocating screw 18, the rectangular block 17 moves up and down. The rectangular block 17 drives the left toothed rod 19 to move up and down. The left toothed rod 19, through the gear 20, causes the right toothed rod 19 to also move up and down continuously. The movement of the toothed rod 19 drives the horizontal bar 16 to move up and down. The horizontal bar 16 drives the moving rod 29 to move up and down. The moving rod 29 drives the top block 44 to move. When the top block 44 moves downward, it can enter the filter holes of the filter plate 7, moving the impurities inside the filter holes downward. For those where the top block 44 does not enter the filter holes, it will cause the moving rod 29 to move upward relative to the horizontal bar 16. It can make appropriate self-adjustment according to the situation of the filter holes, and thus push out the impurities inside the filter holes at different positions. When the rotating rod 9 rotates, it can drive the horizontal bar 16 to move synchronously. The horizontal bar 16 moves up and down under the action of the toothed rod 19, and the moving rod 29 can clean the inside of the filter holes, thus ensuring the filtration effect of the filter plate 7.

[0028] like Figure 7As shown, support blocks 23 are fixedly connected to the opposite sides of the two toothed rods 19. A fifth spring 28 is fixedly connected inside the support block 23. The fifth spring 28 exerts a certain tension on the crossbar 16. One side of the fifth spring 28 is fixedly connected to the crossbar 16. Slide grooves 24 are provided at the upper and lower positions of the support block 23. A slider 27 is slidably connected inside the slide groove 24. The slider 27 can move left and right inside the slide groove 24. Round rods 25 are fixedly connected at the upper and lower positions of the crossbar 16. The rod wall of the round rod 25 is rotatably connected to the inside of the slider 27. The round rod 25 can rotate relative to the slider 27. A return spring 26 is fixedly connected between the round rod 25 and the slider 27. The return spring 26 is used to reset the round rod 25 after it rotates relative to the slider 27. When the top block 44 enters the filter hole, the rotating rod 9 rotates continuously. However, the top block 44 cannot move at this time. The rack 19 continues to move, driving the support block 23 to move. At this time, the fifth spring 28 enables the crossbar 16 to move relative to the support block 23 and rotate relative to the support block 23. This causes the fifth spring 28 and the return spring 26 to deform and be subjected to force. When the top block 44 moves upward and disengages from the filter hole, the crossbar 16 is reset under the action of the fifth spring 28 and the return spring 26. This prevents the top block 44 from getting stuck in the filter hole and affecting the rotation of the rotating rod 9.

[0029] like Figure 1 As shown, a drain pipe 4 is fixedly connected to the lower end of the treatment shell 6 to discharge dirt and the treatment liquid after use.

[0030] Working principle: During operation, gas is introduced into the processing housing 6 through the air inlet pipe 3. This gas exerts a certain blowing force on the blades 10, causing them to move. The blades 10 cause the rotating rod 9 to rotate, which in turn drives the reciprocating groove 31 to rotate. The rotation of the reciprocating groove 31 causes the circular block 33 to move up and down continuously. When the circular block 33 moves upward, it contacts the protrusion 39, causing the protrusion 39 to drive the moving block 34 upward. The upward movement of the moving block 34 compresses the first spring 37. When the elastic force of the first spring 37 reaches a certain level, the circular block 33 continues to move upward, causing it to misalign with the protrusion 39. At this point, the moving block 34 compresses the first spring 37. Under the action of the cone, it moves downward quickly and impacts the upper end of the support plate 43, causing the support plate 43 to vibrate. Through the support rod 35, the lower end of the cone shell 8 vibrates. When the round block 33 moves downward, the moving block 34 is limited by the support plate 43, so that the round block 33 can smoothly pass over the protrusion 39 to reset. This allows the gas and the treatment liquid to come into contact. The vibration of the cone shell 8 can make the gas molecules bounce better, thereby improving the contact effect between the treatment liquid and the gas. At the same time, the vibration can accelerate the reaction speed between the treatment liquid and the gas, thereby improving the removal of harmful substances in the gas. Furthermore, the rotation of the rotating rod 9 drives the rectangular block 17 to rotate. Under the action of the reciprocating screw 18, the rectangular block 17 moves up and down. The rectangular block 17 drives the left toothed rod 19 to move up and down. The left toothed rod 19, through the gear 20, causes the right toothed rod 19 to also move up and down continuously. The movement of the toothed rod 19 drives the horizontal rod 16 to move up and down. The horizontal rod 16 drives the moving rod 29 to move up and down. The moving rod 29 drives the top block 44 to move. When the top block 44 moves downward, it can enter the filter hole of the filter plate 7 and move the impurities inside the filter hole downward. For those where the top block 44 does not enter the filter hole, the moving rod 29 will move upward relative to the horizontal rod 16. It can make appropriate self-adjustment according to the situation of the filter hole, and thus push out the impurities inside the filter hole at different positions. In this way, when the rotating rod 9 rotates, it can drive the horizontal rod 16 to move synchronously. The horizontal rod 16 moves up and down under the action of the toothed rod 19, and the moving rod 29 can clean the inside of the filter hole, thereby ensuring the filtration effect of the filter plate 7. Furthermore, when the top block 44 enters the filter hole, the rotating rod 9 rotates continuously without stopping, but the top block 44 cannot move at this time. The rack 19 continues to move, driving the support block 23 to move. At this time, the fifth spring 28 enables the crossbar 16 to move relative to the support block 23, and the crossbar 16 can rotate relative to the support block 23. This causes the fifth spring 28 and the return spring 26 to deform and be subjected to force. When the top block 44 moves upward and disengages from the filter hole, the crossbar 16 is reset under the action of the fifth spring 28 and the return spring 26. This can prevent the top block 44 from getting stuck in the filter hole and affecting the rotation of the rotating rod 9.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
