Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically to a high-efficiency dust removal device. Background Technology

[0002] Metal processing plants generate metal dust during the processing of metal parts. This dust remains suspended in the air and disperses within and around the factory. Metal dust can also be stirred up by worker activities such as sweeping, handling, and stacking metal materials. Metal dust can negatively impact worker health and pollute equipment and the environment, thus requiring its management.

[0003] Dust removal devices on the market generally remove dust through the filtration effect of filter bags. However, after prolonged use, particulate matter tends to accumulate on the surface of the filter bags, causing them to become clogged. This reduces the gas flow and decreases the filtration effect, requiring regular replacement of the filter bags. Furthermore, frequent replacement of filter bags also reduces the filtration efficiency. Therefore, this invention provides a high-efficiency dust removal device. Summary of the Invention

[0004] The technical problem solved by this invention is that after prolonged use, particulate matter tends to accumulate on the surface of the filter bag in existing dust removal devices, causing the filter bag to become clogged. This reduces the gas flow and decreases the filtration effect, requiring regular replacement of the filter bag. Furthermore, frequent replacement of the filter bag also reduces the filtration efficiency.

[0006] A further technical improvement of the present invention is that: the other end of the second rod is fixedly connected to the third rod, and the third rod is located above the annular baffle.

[0007] A further technical improvement of the present invention is that: multiple water spray nozzles are fixedly connected to the bottom of the annular baffle for humidifying the exhaust gas.

[0008] A further technical improvement of the present invention is that a fan blade is fixedly connected to one end of the first rod above the filter screen, and the fan blade is located above the push rod.

[0009] A further technical improvement of the present invention is that a graphite plate is detachably connected to the No. 1 plate on the side near the No. 1 rod.

[0010] A further technical improvement of the present invention is that: two electromagnetic plates are fixedly connected to the bottom end of the first rod, the electromagnetic plates are located below the air intake pipe, and the surface of the electromagnetic plates is provided with multiple through holes.

[0011] A further technical improvement of the present invention is that: a drain pipe is installed at the bottom of the dust collection box, and a valve is provided on the drain pipe; a liquid level sensor is fixedly installed on the inner wall of the dust collection box to detect the liquid level at the bottom of the dust collection box.

[0012] A further technical improvement of the present invention is that: a cylinder is inserted into the top of the exhaust pipe, an activated carbon plate is provided on the inner wall of the cylinder, and an ear plate is fixedly connected to the top of the cylinder.

[0013] A further technical improvement of the present invention is that: the No. 1 plate has an installation groove on the side near the No. 1 rod, the graphite plate is engaged in the installation groove, the inner wall of the installation groove has a round hole, and a round rod is fixed to one side of the graphite plate, the round rod is inserted through the round hole.

[0014] A further technical improvement of the present invention is that: the end of the round rod away from the graphite plate is provided with a thread, the round rod is fixed to the No. 1 plate by a nut, and a collection groove is provided at the bottom of the mounting groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, when the motor drives rod number one to rotate, rod number one will drive push rod to press plate number one, causing plate number one to drive rod number two to rotate slightly, causing plate number one to leave the top of the filter screen. The torsion spring generates torque. When push rod leaves plate number one, rod number two will rotate due to the action of the torsion spring. At this time, plate number one will hit the filter screen, causing the filter screen to vibrate, which facilitates the shaking off of dust at the bottom of the filter screen, thereby avoiding the problem of filter screen clogging, reducing the number of filter screen replacements, and ensuring the filtration effect of gas.

[0017] 2. In this invention, when the push rod presses the No. 1 plate, it will press the graphite plate. The push rod slides on the surface of the graphite plate, causing frictional heat to be generated on the surface of the graphite plate. This, together with the No. 1 rod, drives the fan blade to rotate. The air generated by the fan blade rotation and the heat combine to help dry the filter screen and ensure the filtration effect of the filter screen.

[0018] 3. In this invention, the motor drives the first rod and the electromagnetic plate to rotate, which on the one hand stirs the water and makes the dust fully contact the water, and on the other hand, by charging the electromagnetic plate, the metal dust is adsorbed on the electromagnetic plate, thereby achieving the separation of metal dust and dust. The separated metal dust and dust can be discharged from the drain pipe respectively, thereby achieving the classification of dust. Attached Figure Description

[0025] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0026] Please see Figures 1-4As shown, a high-efficiency dust removal device includes a dust collection box 1. An air inlet pipe 2 is provided on the side wall of the dust collection box 1, and an exhaust pipe 3 is provided on the top of the dust collection box 1. An annular baffle 4 is fixed to the inner wall of the dust collection box 1, and the annular baffle 4 is located above the air inlet pipe 2. A through groove is opened at the center of the top of the annular baffle 4, and a filter screen 5 is fixedly connected in the through groove. Multiple water spray nozzles 6 are fixed to the bottom of the annular baffle 4 for humidifying the exhaust gas. The water spray nozzles 6 are connected to a water pump through pipes. After the outside gas enters the dust collection box 1 through the air inlet pipe 2, the water pump is started, causing the water pump to draw water from the water tank into the pipe and spray it out from the water spray nozzles 6, thereby humidifying the gas. Simultaneously, metal dust and grime sink to the bottom of the dust collection box 1. At the same time, some gas flows from the filter screen 5 to the top of the annular baffle 4 and is discharged from the exhaust pipe 3, thus achieving dust removal from the gas.

[0027] Furthermore, a cylinder 7 is inserted into the top of the exhaust pipe 3, and an activated carbon plate 8 is provided on the inner wall of the cylinder 7. An ear plate is fixed to the top of the cylinder 7. By providing the activated carbon plate 8 in the exhaust pipe 3, the gas is further purified. At the same time, the cylinder 7 and the exhaust pipe 3 are detachable, making it convenient to replace the activated carbon plate 8.

[0028] Since the water mist sprayed from the nozzle 6 will sink and accumulate at the bottom of the dust collection box 1, in order to agitate this water and allow it to absorb more dust, a rod 9 is rotatably connected through the center of the filter screen 5. The rod 9 is driven by a motor, which is fixedly installed on the top of the dust collection box 1. Two electromagnetic plates 10 are fixedly attached to the bottom of the rod 9. The electromagnetic plates 10 are located below the air inlet pipe 2, and multiple through holes 11 are opened on the surface of the electromagnetic plates 10. A drain pipe 12 is installed at the bottom of the dust collection box 1, and a valve is installed on the drain pipe 12. By starting the motor, the motor drives the rod 9 and the electromagnetic plates 10 to rotate. On the one hand, this agitates the water, allowing the dust to come into full contact with the water. On the other hand, by charging the electromagnetic plates 10, the metal dust is adsorbed onto the electromagnetic plates 10, thereby achieving the separation of metal dust and dust. The separated metal dust and dust can be discharged from the drain pipe 12, thereby achieving the classification of dust.

[0029] Furthermore, to prevent the water level at the bottom of the dust collector 1 from exceeding the air inlet pipe 2, a liquid level sensor 13 is fixedly installed on the inner wall of the dust collector 1. This facilitates the detection of the liquid level at the bottom of the dust collector 1. When the accumulated water at the bottom of the dust collector 1 submerges the liquid level sensor 13, the liquid level sensor 13 transmits a signal to the PLC controller. The PLC controller controls the water pump to stop working, and at the same time, the air inlet pipe 2 also stops intake. Then, the valve is opened, allowing the water containing dust to be discharged from the drain pipe 12 first. After that, the water pump is restarted, and the electromagnetic plate 10 is de-energized, so that the metal dust can be discharged from the drain pipe 12 along with the water flow.

[0030] To prevent dust accumulation on the surface of filter screen 5, which could lead to clogging and reduced filtration efficiency, a second rod 14 is rotatably connected to the inner wall of the dust collector 1. A torsion spring is installed on the shaft of the second rod 14. A plate 15 is fixedly connected to one end of the second rod 14 near the first rod 9, and the first plate 15 is positioned above the filter screen 5. A push rod 16 for pressing the first plate 15 is also fixedly connected to the outer wall of the first rod 9. A third rod 17 is fixedly connected to the other end of the second rod 14, and the third rod 17 is positioned above the annular baffle 4. When the motor drives the first rod 9 to rotate, it will cause the first rod 9 to drive the push rod 16... Rod 16 presses against plate 15, causing plate 15 to drive rod 14 to rotate slightly. At this time, the bottom end of rod 17 will hit the annular baffle 4, causing the annular baffle 4 to vibrate and shake off the dust at the bottom of the annular baffle 4. At the same time, after push rod 16 leaves plate 15, due to the action of torsion spring, rod 14 will rotate. At this time, plate 15 will hit filter screen 5, causing filter screen 5 to vibrate, which facilitates the shaking off of dust at the bottom of filter screen 5, thereby avoiding the problem of filter screen 5 clogging, reducing the number of times filter screen 5 needs to be replaced, and ensuring the filtration effect of gas.

[0031] Because of the water spraying action of the spray nozzle 6, the filter screen 5 will be in a wet state, which will affect the filtration effect of the filter screen 5. When the push rod 16 presses the first plate 15, it will cause the push rod 16 to press the first plate 15, which will generate frictional heat on the surface of the first plate 15. In order to transfer this heat to the surface of the filter screen 5 and dry the filter screen 5, a fan blade 18 is fixedly connected to the end of the first rod 9 above the filter screen 5, and the fan blade 18 is located above the push rod 16.

[0032] Furthermore, in order to improve the effect of frictional heat generation, a graphite plate 19 is detachably connected to the first plate 15 on the side near the first rod 9. More heat is generated through the friction between the push rod 16 and the graphite plate 19, which, together with the wind generated by the rotation of the fan blade 18, is conducive to the drying of the filter screen 5.

[0033] In the above description, the installation structure between graphite plate 19 and plate 15 is as follows: plate 15 has an installation groove 22 on the side near rod 9, graphite plate 19 is engaged in the installation groove 22, the inner wall of the installation groove 22 has a round hole, a round rod 20 is fixed to one side of graphite plate 19, and the round rod 20 is inserted through the round hole; the end of the round rod 20 away from graphite plate 19 is threaded, and the round rod 20 is fixed to plate 15 by nut 21; when installing activated carbon plate 8, first insert the round rod 20 into the round hole so that one side of graphite plate 19 is in close contact with the inner wall of the installation groove 22, and then screw the nut 21 in from the other side of plate 15, thereby fixing graphite plate 19 in the installation groove 22;

[0034] A collection groove 23 is provided at the bottom of the mounting groove 22. When the graphite plate 19 is worn, its powder will fall into the collection groove 23, preventing the powder from falling on the top of the filter screen 5.

[0035] In use, external gas enters the dust collector 1 through the inlet pipe 2. A water pump is activated, drawing water from the tank into the pipe and spraying it from the nozzle 6, humidifying the gas. This causes metal dust and other particles to settle to the bottom of the dust collector 1. Simultaneously, some gas flows from the filter screen 5 to the top of the annular baffle 4 and is discharged through the exhaust pipe 3, thus achieving dust removal. Activating the motor rotates the first rod 9 and the electromagnetic plate 10, agitating the water to ensure thorough contact between the dust and water. Simultaneously, charging the electromagnetic plate 10 causes the metal dust to adhere to it, separating the metal dust and other particles. The separated metal dust and other particles are discharged through the drain pipe 12, achieving dust classification. When the motor rotates the first rod 9, it causes the first rod... Push rod 16, driven by rod 9, presses against plate 15, causing plate 15 to rotate slightly, which in turn causes rod 14 to rotate slightly. At this time, the bottom of rod 17 will hit the annular baffle 4, causing the annular baffle 4 to vibrate and shake off the dust at the bottom of the annular baffle 4. Simultaneously, after push rod 16 leaves plate 15, rod 14 will rotate due to the action of the torsion spring. At this time, plate 15 will hit filter screen 5, causing filter screen 5 to vibrate, which facilitates the shaking off of dust at the bottom of filter screen 5, thereby avoiding the problem of filter screen 5 clogging, reducing the number of times filter screen 5 needs to be replaced, and ensuring the filtration effect of gas. When push rod 16 presses against plate 15, it will press against graphite plate 19, causing frictional heat to be generated on the surface of graphite plate 19. Combined with the rotation of fan blade 18 driven by rod 9, the air generated by the rotation of fan blade 18 and the heat are conducive to the drying of filter screen 5, ensuring the filtration effect of filter screen 5.
