Description

Technical Field

[0001] The invention relates to the technical field of metal casting, and in particular to a casting fume treatment system and a use method thereof. Background Art

[0002] Casting is an ancient and important metal processing technology, which forms parts or products of predetermined shapes by injecting molten metal into a mold and waiting for it to cool and solidify. This process is widely used in the manufacture of various mechanical parts, tools and artworks. Casting not only has high precision and consistency, but also can produce components of complex shapes to meet diverse needs. However, during the casting process, smoke pollution is usually generated.

[0003] Existing smoke and dust filtration usually directly relies on a filter to filter the smoke and dust.

[0004] The existing patent (publication number: CN115055009A) discloses an automatic smoke treatment device for automobile brake hub casting equipment, including a box body, a connection seat is fixedly connected at the bottom center of the box body, a base is fixedly connected to the end of the connection seat, a self-locking universal wheel is fixedly installed at the bottom of the base at equal intervals, an air inlet is opened at equal intervals on the surface of the box body, and a collection box is slidably installed on the outer surface of the box body. The present invention can adsorb smoke in multiple directions by installing a guide plate, thereby enhancing flexibility, and by setting a guide plate, the direction of smoke drifting can be guided, which speeds up the time for smoke to enter the box body, so that the smoke can be quickly filtered. By installing a spring, when the vibration motor inside the outer frame is started, the filter screen can be shaken at a high frequency inside the box body to clean the dust adhering to the surface of the filter screen, and due to the shape of the outer frame and the filter screen, the efficiency of dust shaking is also enhanced. Existing smoke filtration usually uses a filter screen, which directly relies on the filter screen for smoke filtration, causing the filter screen to be easily clogged and requiring frequent filter screen replacement, increasing maintenance costs and workload. The device uses vibration to shake off the smoke on the filter screen. Long-term vibration may affect the threaded connection or have a certain impact on internal components, and replacing the filter screen may require manual disassembly and installation of the filter screen frame. This process is not only cumbersome but also time-consuming, affecting production efficiency.

[0005] In view of this, we propose a casting fume treatment system and a method of use. Summary of the invention

[0019] A method for using a casting smoke treatment system comprises the following steps:

[0020] S1. Place the entire device on top of the casting equipment and align the smoke exhaust port with the smoke recovery bin, or place the device in the casting equipment site, actively suction the smoke through the smoke through the slot opened on the smoke recovery bin, and drive the dust suction fan blades inside the smoke recovery bin to actively suction the smoke generated by the casting equipment during operation through a driving motor, and perform filtering treatment;

[0021] S2. The smoke enters the water curtain filter chamber through the smoke recovery chamber. Clean water is injected into the water curtain buffer chamber in advance. The active worm connected to the top of the drive motor is started to drive the driven worm gear to rotate, and the driven worm gear drives the external vane pump to rotate. The vane pump extracts clean water from the water curtain buffer chamber through the connecting hose. When the clean water enters the water curtain output end through the water curtain connecting pipe, the water flow is flattened to form a water curtain, and the water flow is sprayed out through the water curtain output shell. The water curtain passes through the water curtain through the groove to cover the entire water curtain filter chamber, and the tiny particles mixed in the smoke are brought into the water curtain recovery chamber, and are guided to the water curtain filter through the drainage groove for filtration and then enter the water curtain buffer chamber again for circulation. When the water flows through the water curtain filter bin, it will push the internal driving blade to rotate. The driving blade drives the blade threaded rod to rotate in the internal threaded sleeve through the blade chassis. The blade threaded rod extends outward and pushes the external cylindrical cam to move outward. The blade reset spring is a torsion spring and drives the blade threaded rod to reset when the water flow power is insufficient. The cylindrical cam moves outward to drive the driven turntable connected to it to rotate. The driven turntable drives the direct-acting sliding block to reciprocate through the connecting rod. The direct-acting sliding block pushes and pulls the L-shaped plate through the push-pull rod while moving horizontally, so that the L-shaped plate can block or open the water curtain guide groove on the water curtain output housing. The cylindrical cam is reset by the cylindrical reset spring.

[0022] S3. The filter frame is installed on the filter clamping mechanism in the filter filtration bin, and the spare filter is installed in the filter replacement mechanism. The clamping mounting plate is pulled out into the filter replacement bin through the handle bracket. The clamping mounting plate clamps the filter frame through the clamping plate. At this time, observe the use of the filter through the window plate. If the filter needs to be replaced, pull the pull rod backwards. At this time, the pull rod drives the sliding plate to move backwards. A path control groove is opened on the sliding plate. The clamping plate can only move linearly in the clamping mounting plate and is controlled by the path control groove. The path control groove is composed of a straight line and an oblique line segment, and the top and the bottom are opposite, so that the displacement direction of the clamping plate is opposite when the sliding plate moves. By pulling the sliding plate, the inner clamping plate is first located in the straight line segment and the outer clamping plate is located in the oblique line segment. The inner clamping plate first does not move and moves inwards toward the outside until the inner clamping plate is located in the oblique line segment and the outer clamping plate enters the straight line segment and moves to the maximum inner distance. The inner clamping plate moves outward and no longer supports the filter frame, so that the filter frame falls into the filter recovery seat at the bottom. At this time, release the pull rod and reset it under the action of the pull rod reset spring. The pull rod will drive the top ramp block to move in a straight line during the pulling process. When the filter clamping mechanism is pulled to the filter replacement bin, the ramp block contacts the contact wheel of the filter replacement mechanism. During the backward movement of the ramp block, the contact wheel is pushed upward and drives the active rack upward. The active rack drives the driven gear meshing with it to rotate, and the driven gear drives the ratchet turntables at both ends to rotate. The ratchet turntable, the ratchet connecting rod and the active ratchet form a crank rocker structure, which drives the active ratchet The driven ratchet is pushed to rotate, and the driven ratchet drives the gear support shaft and the transmission gear through the connecting shaft, and finally drives the clamping chain belt set on the outside to transmit downward. The clamping chains on both sides are used to clamp the filter frame to be replaced. When the clamping chain is transmitted downward, the filter frame is lowered to the clamping plate on the filter clamping mechanism to achieve a one-time filter replacement. When the ramp block is reset with the pull rod, the active rack moves downward under the influence of gravity, and the driven gear reverses. However, due to the setting of the ratchet pawl, the ratchet cannot be reversed to prevent the clamping chain belt from transmitting in the opposite direction.

[0023] S4. When the device is finished running, the electric push rod on the blade cleaning mechanism is started, which presses the push plate down and presses the contact protrusion on the cam block through the spiral path groove on the push claw, so that the contact protrusion rotates. The cleaning wipe is sleeved on the surface of the dust suction fan blade, and the cleaning wipe is pushed outward by the contact protrusion and the cleaning reset spring is pulled until the connecting hard pipe is inserted into the valve on the small water storage tank. The small water storage tank receives water from the water curtain buffer tank through the water injection pipe and distributes it through the connecting pipe. The valve is used to block the water outlet of the small water storage tank. When the connecting hard pipe is inserted, the valve opens it, and the water flows into the cleaning wipe through the connecting hard pipe. At this time, the electric push rod retreats, and the push plate is reset under the action of the push plate reset spring. The cam block is reset and the cleaning wipe is driven to reset by the cleaning reset spring. The surface of the dust suction fan blade is cleaned by the cleaning wipe with water.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] In the present invention, by setting up a water curtain circulation mechanism, the casting smoke is first filtered through the water curtain, which reduces the frequency of filter replacement and can circulate water. When the water flow power is insufficient to form a water curtain, the water curtain self-locking mechanism can be forced to close to prevent water from falling to the ground or the surface of the casting equipment.

[0026] In the present invention, by setting up the filter clamping mechanism and the filter replacing mechanism, by pulling the pulling rod and utilizing the path control groove to realize the control of different displacement requirements of the upper and lower clamping plates, the upper and lower clamping plates can simultaneously lower the original filter frame and the filter frame receiving the top, and use the gear to drive the chain to clamp the spare filter frame, and utilize the movement and resetting of the pulling rod on the filter clamping mechanism to drive the gear rack and the ratchet pawl mechanism to rotate the clamping chain belt to lower the filter frame, and it has the effect of preventing reversal, preventing the clamping chain from driving the filter frame to retreat.

[0027] In the present invention, by setting up the blade cleaning mechanism, the conversion between linear motion and rotation is realized through the electric push rod and the cam, and the movement of the cleaning wipe is dispersed in three directions, so that the blades are cleaned simultaneously.

[0072] S2, smoke and dust enter the water curtain filter chamber 2 through the smoke recovery chamber 1, and clean water is injected into the water curtain buffer chamber 44 in advance. The active worm 41 connected to the top of the drive motor 13 is started to drive the driven worm gear 42 to rotate, and the driven worm gear 42 drives the external vane pump 48 to rotate. The vane pump 48 extracts clean water in the water curtain buffer chamber 44 through the connecting hose 46. When the clean water enters the water curtain output end 51 through the water curtain connecting pipe 49, the water flow is flattened to form a water curtain, and the water flow is sprayed out through the water curtain output shell 52. The water curtain passes through the water curtain through the groove 21 to cover the entire water curtain filter chamber 2, and the tiny particles mixed in the smoke and dust are brought into the water curtain recovery chamber 45, and are guided to the water curtain filter 471 through the drainage groove 451 for filtration and then enter the water curtain buffer chamber 44 again for recycling. When the water flows through the water curtain, the water curtain filter 471 is filtered and then enters the water curtain buffer chamber 44 for recycling. When the curtain filters the bin 2, the internal driving blade 55 is pushed to rotate. The driving blade 55 drives the blade threaded rod 57 to rotate in the internal threaded sleeve 571 through the blade chassis 56. The blade threaded rod 57 extends outward and pushes the external cylindrical cam 511 to move outward. The blade reset spring 58 is a torsion spring and drives the blade threaded rod 57 to reset when the water flow power is insufficient. The cylindrical cam 511 moves outward to drive the driven turntable 515 connected thereto to rotate. The driven turntable 515 drives the direct-acting sliding block 517 to reciprocate through the connecting rod 516. The direct-acting sliding block 517 pushes and pulls the L-shaped plate 520 through the push-pull rod 519 while moving horizontally, so that the L-shaped plate 520 can block or open the water curtain guide groove 53 on the water curtain output housing 52.

The clamping mounting plate 62 clamps the filter frame 7 through the clamping plate 68 at this time. At this time, by observing the use of the filter through the window plate 33, if the filter needs to be replaced, the pulling rod 65 is pulled backward. At this time, the pulling rod 65 drives the sliding plate 66 to move backward. A path control groove 67 is opened on the sliding plate 66. The clamping plate 68 can only move linearly in the clamping mounting plate 62 and is controlled by the path control groove 67 The path control groove 67 is composed of a straight line and an oblique line segment, and the top and the bottom are opposite, so that the displacement direction of the clamping plate 68 is opposite when the sliding plate 66 moves. By pulling the sliding plate 66, the inner clamping plate 68 is first located in the straight line segment and the outer clamping plate 68 is located in the oblique line segment. The inner clamping plate 68 first does not move and moves inward from the outside until the inner clamping plate 68 is located in the oblique line segment and the outer clamping plate 68 enters the straight line segment and moves to the maximum inner distance. The inner clamping plate 68 moves outward and no longer supports the filter frame 7, so that the filter frame 7 falls into the filter recovery seat 34 at the bottom. At this time, the pull rod 6 is released. 5 and resets under the action of the pull rod reset spring 64. The pull rod 65 drives the top ramp block 69 to move linearly during the pulling process. When the filter clamping mechanism 6 is pulled to the filter replacement bin 32, the ramp block 69 contacts the contact wheel 89 of the filter replacement mechanism 8. During the backward movement of the ramp block 69, the contact wheel 89 is pushed upward and the active rack 87 is pushed upward. The active rack 87 drives the driven gear 810 meshing with it to rotate. The driven gear 810 drives the ratchet turntables 811 at both ends to rotate. The ratchet turntable 811, the ratchet connecting rod 812 and the active ratchet 813 form a crank rocker structure to drive the active rack 87 to rotate. The pawl 813 pushes the driven ratchet 85 to rotate, and the driven ratchet 85 drives the gear support shaft 81 and the transmission gear 82 through the connecting shaft 84, and finally drives the clamping chain belt 83 set on the outside to transmit downward. The clamping chain belts 83 on both sides are used to clamp the filter frame 7 to be replaced. When the clamping chain is transmitted downward, the filter frame 7 is lowered to the clamping plate 68 on the filter clamping mechanism 6 to achieve a one-time filter replacement. When the ramp block 69 is reset with the pull rod 65, the active rack 87 moves downward under the influence of gravity, and the driven gear reverses. However, due to the setting of the ratchet pawl, the ratchet cannot be reversed to prevent the clamping chain belt 83 from reverse transmission;

[0074] S4. When the device is finished running, the electric push rod 95 on the blade cleaning mechanism 9 is started, which presses the push plate 98 down, and presses the contact protrusion 912 on the cam block 911 through the spiral path groove 910 on the push claw 99, so that the contact protrusion 912 rotates, and the cleaning wipe 96 is sleeved on the surface of the dust suction fan blade 14, and the cleaning wipe 96 is pushed outward by the contact protrusion 912 and the cleaning reset spring 914 is pulled until the connecting hard pipe 97 is inserted into the valve 93 on the small water storage tank 92, and the small water storage tank 92 is filled with water. The water pipe 94 receives water from the water curtain buffer bin 44 and distributes it through the connecting pipe 91. The valve 93 is used to block the water outlet of the small water storage bin 92. When the connecting hard pipe 97 is inserted, the valve 93 opens it, and the water flows through the connecting hard pipe 97 into the cleaning wipe 96. At this time, the electric push rod 95 retreats, and the push plate 98 is reset under the action of the push plate reset spring 913. The cam block 911 is reset and the cleaning wipe 96 is driven to reset through the cleaning reset spring 914. The surface of the dust collector blade 14 is cleaned by the cleaning wipe 96 with water.

9. A method for using a casting fume treatment system, characterized in that: Using a casting smoke treatment system as described in any one of claims 1 to 8 comprises the following steps: S1. The entire device is placed on top of the casting equipment, and the smoke exhaust port is aligned with the smoke recovery bin (1), or the device is placed in the casting equipment site, and the smoke is actively sucked through the smoke through the slot (11) opened on the smoke recovery bin (1), and the smoke recovery inside is driven by the driving motor (13) to drive the dust suction fan blade (14) to actively suck the smoke generated when the casting equipment is working, and perform filtering treatment; S2, smoke enters the water curtain filter chamber (2) through the smoke recovery chamber (1), clean water is injected into the water curtain buffer chamber (44) in advance, the driving motor (13) is started, and the active worm (41) connected to the top of the driving motor (13) drives the driven worm gear (42) to rotate, and the driven worm gear (42) drives the external vane pump (48) to rotate, and the vane pump (48) extracts clean water in the water curtain buffer chamber (44) through the connecting hose (46). When the clean water passes through the water curtain connecting pipe (4 9) enters the water curtain output end (51) to flatten the water flow to form a water curtain, and sprays the water flow through the water curtain output housing (52). The water curtain passes through the water curtain through the groove (21) to cover the entire water curtain filter chamber (2), and brings the tiny particles mixed in the smoke into the water curtain recovery chamber (45), and guides them to the water curtain filter screen (471) through the drainage groove (451) for filtration before entering the water curtain buffer chamber (44) for recycling. When the water flows through the water curtain filter chamber (2), it drives the internal driving blade (55) to rotate. The driving blade (55) drives the blade threaded rod (57) to rotate in the internal threaded sleeve (571) through the blade chassis (56). The blade threaded rod (57) extends outward and pushes the external cylindrical cam (511) to move outward. The blade reset spring (58) is a torsion spring and drives the blade threaded rod (57) to reset when the water flow power is insufficient. The cylindrical cam (511) moves outward and drives the blade threaded rod (57) connected to it to rotate. The driven rotating disk (515) connected thereto rotates, and the driven rotating disk (515) drives the direct-acting sliding block (517) to move back and forth through the connecting rod (516). The direct-acting sliding block (517) pushes and pulls the L-shaped plate (520) through the push-pull rod (519) while moving laterally, so that the L-shaped plate (520) can block or open the water curtain guide groove (53) on the water curtain output housing (52), and the cylindrical cam (511) is reset through the cylindrical reset spring (512); S3, the filter frame (7) is installed on the filter clamping mechanism (6) in the filter filter bin (3), and the spare filter is installed in the filter replacement mechanism (8). The clamping mounting plate (62) is pulled out into the filter replacement bin (32) through the handle bracket (63). The clamping mounting plate (62) clamps the filter frame (7) through the clamping plate (68). At this time, by observing the use of the filter through the window plate (33), if the filter needs to be replaced, the pull rod (65) is pulled backward. At this time, the pull rod (65) drives the sliding plate (66) to move backward. The sliding plate (66) is provided with a path control groove (67). The clamping plate (68) can only move linearly in the clamping mounting plate (62) and pass through the path control groove ( 67), the path control groove (67) is composed of a straight line and an oblique line segment and the top and the bottom are opposite, so that when the sliding plate (66) moves, the displacement direction of the clamping plate (68) is opposite. By pulling the sliding plate (66), the inner clamping plate (68) is first located in the straight line segment and the outer clamping plate (68) is located in the oblique line segment. The inner clamping plate (68) first does not move and moves inward from the outside until the inner clamping plate (68) is located in the oblique line segment and the outer clamping plate (68) enters the straight line segment and moves to the maximum distance inward. The inner clamping plate (68) moves outward and no longer supports the filter frame (7), so that the filter frame (7) falls into the filter recovery seat (34) at the bottom. At this time, the pulling rod (65) is released. The pull rod (65) is reset under the action of the pull rod reset spring (64). The pull rod (65) drives the top ramp block (69) to move linearly during the pulling process. When the filter screen clamping mechanism (6) is pulled to the filter screen replacement bin (32), the ramp block (69) contacts the contact wheel (89) of the filter screen replacement mechanism (8). During the backward movement of the ramp block (69), the contact wheel (89) is pushed upward and the active rack (87) is pushed upward. The active rack (87) drives the driven gear (810) meshing therewith to rotate. The driven gear (810) drives the ratchet rotating discs (811) at both ends to rotate. The ratchet rotating disc (811), the ratchet connecting rod (812) and the active ratchet (813) form a crank rocker structure to drive the driven gear (810) to rotate. The active ratchet pawl (813) drives the driven ratchet (85) to rotate. The driven ratchet (85) drives the gear support shaft (81) and the transmission gear (82) through the connecting shaft (84), and finally drives the clamping chain belt (83) provided on the outside to transmit downward. The clamping chain belts (83) on both sides are used to clamp the filter frame (7) to be replaced. When the clamping chain is transmitted downward, the filter frame (7) is lowered to the clamping plate (68) on the filter clamping mechanism (6), so that the filter can be replaced once. When the ramp block (69) is reset along with the pull rod (65), the active rack (87) moves downward under the influence of gravity, and the driven gear reverses. However, due to the setting of the ratchet pawl, the ratchet cannot reverse to prevent the clamping chain belt (83) from transmitting in the reverse direction. S4. When the device is finished running, the electric push rod (95) on the blade cleaning mechanism (9) is started, which presses the push plate (98) downward, and presses the contact protrusion (912) on the cam block (911) through the spiral path groove (910) on the push claw (99), so that the contact protrusion (912) rotates, and the cleaning wipe (96) is sleeved on the surface of the dust suction fan blade (14). The cleaning wipe (96) is pushed outward by the contact protrusion (912) and the cleaning reset spring (914) is pulled until the connecting hard pipe (97) is inserted into the valve (93) on the small water storage tank (92), and the small water storage tank (92) is filled with water through the water injection pipe. (94) receives water from the water curtain buffer chamber (44) and distributes it through the connecting pipe (91). The valve (93) is used to block the water outlet of the small water storage chamber (92). When the connecting hard pipe (97) is inserted into the valve (93), the valve (93) is opened, and the water flows into the cleaning wipe (96) through the connecting hard pipe (97). At this time, the electric push rod (95) retreats, and the push plate (98) is reset under the action of the push plate reset spring (913). The cam block (911) is reset and drives the cleaning wipe (96) to reset through the cleaning reset spring (914). The surface of the dust suction fan blade (14) is cleaned by the cleaning wipe (96) filled with water.
