Description

Technical Field

[0001] The present invention relates to the technical field of dust purification, in particular to an air purification device for high-dust workshops. Background Art

[0002] In the automotive manufacturing industry, the generation of metal dust and other dust is unavoidable. This dust primarily originates from processes such as cutting, welding, and grinding of automotive parts. Metal dust is not only harmful to worker health but can also cause fires and explosions, while also polluting production equipment and the environment.

[0003] Traditional filtering purification devices are large in size. Large mechanical dust purification devices are usually fixedly installed on the roof of the factory, which is difficult to move and cannot be flexibly adjusted according to production needs. In addition, large mechanical dust purification devices have poor adaptability to different types of dust and different production areas and are difficult to meet diverse needs. Mechanical filtering devices not only require regular replacement of filters, but their high-power fans and complex piping systems are also prone to wear and tear due to the purification of metal dust under long-term work, requiring frequent maintenance and replacement of parts, which increases the maintenance cost and replacement frequency of the equipment.

An electromagnetic generator is provided at the bottom of the water bath box, and the electromagnetic generator is electrically connected to the electromagnetic plate. A power supply for powering the electromagnetic generator is provided on one side of the electromagnetic generator.

[0009] Preferably, the gas guide device includes an L-shaped guide plate 1, which is arranged on the side of the water bath box close to the air inlet pipe, and a guide plate 2 is provided in the middle and lower part of the water bath box. An arc-shaped guide plate 3 is provided on the side of the guide plate 1 close to the guide plate 2, and the guide plate 3 covers the guide plate 2.

[0010] Preferably, a roller is provided at the bottom of the water bath body, a door is provided on a side of the water bath body away from the air inlet pipe, and a sealing strip is provided at the edge of the door.

[0011] Preferably, the bottom of the water bath box is tilted, and the water bath box is provided with a collection bin below the box door. The water bath box is connected to the collection bin, a water pipe is provided on one side of the collection bin, a water valve is provided on the water pipe, and a detachable baffle is provided on the top of the collection bin, and a sealing layer is provided at the edge of the baffle.

[0012] Preferably, an opening is provided on one side of the fan housing, an activated carbon adsorption layer is inserted into the opening, the activated carbon adsorption layer is located above the motor, and a handle is provided at one end of the opening of the activated carbon adsorption layer.

[0013] Preferably, one end of the top of the guide plate one is connected to the inner wall of the water bath box above the air inlet pipe, and the bottom end of the guide plate one is arranged toward the bottom of the water bath box, and the horizontal height of the bottom end of the guide plate one is higher than the horizontal height of the bottom end of the guide plate two, and one end of the guide plate three is connected to the side wall of the guide plate one, and the other end of the guide plate three is arranged toward the bottom of the water bath box, and the horizontal height of one end of the guide plate three toward the bottom of the water bath box is lower than the horizontal height of the top of the guide plate two.

[0014] The beneficial effects of the embodiments of the present invention are: 1. This device uses water splashes to wash the powder-laden gas passing through water. The metal dust and dust in the gas are washed into the water. The clean gas enters the fan box and is discharged to the outside through the exhaust device. Since an electromagnetic adsorption device is provided at the bottom of the water bath box, the electromagnetic adsorption device can adsorb the metal dust at the bottom of the water bath box, preventing the metal dust from being re-suspended from the water into the gas phase, resulting in a decrease in the dust purification effect. At the same time, it prevents the metal dust from swirling with the water splashes at the bottom of the water bath box, causing damage to the gas guide device.

[0015] 2. By rotating the rotating cover, the multiple shielding pieces 1 on the upper part of the rotating cover can cooperate with the multiple shielding pieces 2 on the top of the air outlet pipe to form a complete circular baffle in cooperation with the annular limit block and the annular groove, thereby preventing external dust from entering the interior of the device; when using the device, by rotating the rotating cover, the multiple shielding pieces 1 on the upper part of the rotating cover can overlap with the multiple shielding pieces 2 on the top of the air outlet pipe in cooperation with the annular limit block and the annular groove, thereby ensuring that the air outlet pipe is connected to the outside, thereby facilitating the discharge of gas inside the device to the outside.

[0016] 3. This device generates a magnetic field on the battery panel through the transmission of electric current. When metal dust enters the water, it is adsorbed on the electromagnetic plate at the bottom of the water bath due to the action of the electromagnetic plate. When the purification is completed, the magnetism on the electromagnetic plate disappears by turning off the power, making it easier to collect and clean the metal dust on the electromagnetic plate.

[0017] 4. The highest water level inside the water bath of this device is higher than the bottom of guide plate 1, and there is a gap between the bottom of guide plate 2 and the bottom of the water bath. The lowest end of guide plate 3 is higher than the highest water level. When external air enters the water bath, due to the suction effect of the suction device, a negative pressure is formed inside the water bath. At this time, the highest water level at the bottom of guide plate 1 is constantly higher and lower than the horizontal height of the bottom of guide plate 1 (when the water level is lower than the horizontal height of the bottom of guide plate 1, external air can enter between guide plates 1 and 2. At this time, the air pressure inside the water bath is instantly restored, and the water level rises again to be parallel to the lowest end of guide plate 1. When the water level is parallel to the lowest end of guide plate 1, the water bath is The internal air pressure drops again, so the water level rises and falls repeatedly). As the water level at one guide plate rises and falls continuously, water splashes continuously form between guide plates one and two, and the gas entering between guide plates one and two is continuously flushed clean. Some water in the clean gas follows the gas to move to the upper part between guide plates one and two. Since an arc-shaped guide plate three is provided on the side of guide plate one and the top of guide plate two, which crosses the top of guide plate two, some water in the gas is blocked by the arc-shaped guide plate three and falls into the water. The clean gas rises toward the upper fan box of the water bath until it passes through the fan box and is discharged from the outlet pipe.

[0018] 5. This device is provided with an opening on one side of the fan housing and an activated carbon adsorption layer at the opening, which can adsorb a small amount of water vapor in the gas after the water bath to ensure the dryness of the exhaust gas. A handle is provided on one side of the activated carbon adsorption layer to facilitate the operator to quickly install or remove it, and to facilitate the removal of the activated carbon adsorption layer for drying after purification, thereby facilitating subsequent purification work.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0022] Example 1 An air purification device for high dust workshop, such as Figure 1-Figure 5 As shown, it includes a water bath box body 1, a fan box body 2 connected to the water bath box body 1 is provided on the top, a suction device is provided inside the fan box body 2, an exhaust device is provided on the top of the fan box body 2, an air inlet pipe 3 is provided on one side of the middle part of the water bath box body 1, an electromagnetic adsorption device is provided at the bottom of the water bath box body 1, and a gas guide device is provided on the side of the water bath box body 1 close to the air inlet pipe 3.

[0023] When the suction device is started, the air pressure inside the water bath box 1 decreases. Since the water bath box 1 is filled with water and the water submerges the bottom of the gas guide device and is located below the air inlet pipe 3, when the water bath box 1 is lowered, the metal dust and dust from the outside enter the water bath box 1 through the air inlet pipe 3 and are introduced into the water through the gas guide device. Due to the suction of the suction device and the cooperation of the gas guide device, the dust-containing gas will float again after passing through the guide device into the water, thereby forming a water splash to wash the powder-containing gas passing through the water. The metal dust and dust in the gas are all washed into the water, and the clean gas enters the fan box 2 and is discharged to the outside through the exhaust device. Since an electromagnetic adsorption device is provided at the bottom of the water bath box 1, the electromagnetic adsorption device can adsorb the metal dust at the bottom of the water bath box 1, preventing the metal dust from being re-suspended from the water into the gas phase, resulting in a reduction in the dust purification effect, and at the same time preventing the metal dust from swirling with the water splash at the bottom of the water bath box 1, causing damage to the gas guide device.

[0024] The suction device includes a mounting shell 11. A through hole is opened between the top of the water bath box 1 and the bottom of the fan box 2. The mounting shell 11 is arranged at the through hole. A mounting frame 12 is provided inside the mounting shell 11. Fan blades 13 are provided at the bottom of the mounting frame 12. A motor 14 for driving the fan blades 13 is provided at the top of the mounting frame 12.

[0025] By starting the motor 14, the fan blades 13 installed at the bottom can be driven to rotate. When the fan blades 13 rotate, the gas in the water bath box 1 can be discharged from the device, which is convenient for pumping negative pressure inside the water bath box 1, ensuring that water can effectively clean the dust-containing gas, without using a water pump to spray the gas, thereby ensuring the cleaning efficiency of the dust-containing gas.

[0026] The exhaust device includes an air outlet pipe 4, the outer wall of the air outlet pipe 4 is provided with an annular groove 6, the outer side of the air outlet pipe 4 is provided with a rotating cover 5, the inner wall of the rotating cover 5 is provided with an annular limit block 7 adapted to the annular groove 6, the top of the air outlet pipe 4 is provided with a fan-shaped shielding piece 1 8, and the top of the rotating cover 5 is provided with a shielding piece 2 9 adapted to the shielding piece 1 8.

[0027] When the device is not in use, by rotating the rotating cover 5, with the cooperation of the annular limit block 7 and the annular groove 6, the multiple shielding pieces 8 on the upper part of the rotating cover 5 can cooperate with the multiple shielding pieces 2 9 on the top of the outlet pipe 4 to form a complete circular baffle 17, thereby preventing external dust from entering the interior of the device; when the device is in use, by rotating the rotating cover 5, with the cooperation of the annular limit block 7 and the annular groove 6, the multiple shielding pieces 8 on the upper part of the rotating cover 5 can overlap with the multiple shielding pieces 2 9 on the top of the outlet pipe 4, thereby ensuring that the outlet pipe 4 is connected to the outside, thereby facilitating the discharge of gas inside the device to the outside.

[0028] The electromagnetic adsorption device includes an electromagnetic plate 19, which is arranged on one side of the bottom of the water bath box 1 near the air inlet pipe 3. An electromagnetic generator 20 is provided at the bottom of the water bath box 1. The electromagnetic generator 20 is electrically connected to the electromagnetic plate 19, and a power supply 21 for powering the electromagnetic generator 20 is provided on one side.

[0029] When the device is started, the power supply 21 supplies energy to the electromagnetic generator 20, ensuring that the electromagnetic generator 20 is directly connected to the electromagnetic plate 19 through a wire. The transmission of current causes the battery plate to generate a magnetic field. When metal dust enters the water, due to the action of the electromagnetic plate 19 at the bottom of the water bath, the metal dust is adsorbed on the electromagnetic plate 19. When the purification is completed, by turning off the power supply 21, the magnetism on the electromagnetic plate 19 disappears, making it easier to collect and clean the metal dust on the electromagnetic plate 19.

[0030] The gas guiding device includes an L-shaped guide plate 1 22, which is disposed on a side of the water bath body 1 near the air inlet pipe 3. A guide plate 2 23 is disposed in the middle and lower portion of the water bath body 1. A curved guide plate 3 24 is disposed on a side of the guide plate 1 22 near the guide plate 2 23. The guide plate 3 24 covers the guide plate 2 23. One end of the top of the guide plate 1 22 is connected to the inner wall of the water bath body 1 above the air inlet pipe 3. The bottom end of the guide plate 1 22 is disposed toward the bottom of the water bath body 1. The bottom end of the guide plate 1 22 is higher than the bottom end of the guide plate 2 23. One end of the guide plate 3 24 is connected to the side wall of the guide plate 1 22. The other end of the guide plate 3 24 is disposed toward the bottom of the water bath body 1. The bottom end of the guide plate 3 24 is lower than the top end of the guide plate 2 23.

[0031] The highest water level line inside the water bath box body 1 is higher than the bottom end of the guide plate 1 22, and there is a gap between the bottom of the guide plate 23 and the bottom of the water bath box, and the lowest end of the guide plate 3 24 is higher than the highest water level line. When external air enters the interior of the water bath box body 1, due to the suction effect of the suction device, a negative pressure is formed inside the water bath box body 1. At this time, the highest water level line at the bottom end of the guide plate 1 22 is constantly higher than and lower than the horizontal height of the bottom of the guide plate 1 22 (when the water level line is lower than the horizontal height of the bottom end of the guide plate 1 22, external air can enter between the guide plate 1 22 and the guide plate 2 23. At this time, the air pressure inside the water bath box body 1 is instantly restored, and the water level line rises again to be parallel to the lowest end of the guide plate 1 22. When the water level line is parallel to the lowest end of the guide plate 1 22, the air inside the water bath box body 1 is restored. The pressure drops again, so the water level rises and falls repeatedly). As the water level at the guide plate 1 22 rises and falls continuously, water splashes are continuously formed between the guide plate 1 22 and the guide plate 2 23, and the gas entering between the guide plate 1 22 and the guide plate 2 23 is continuously flushed clean. Some water contained in the clean gas follows the gas to move to the upper part between the guide plate 1 22 and the guide plate 2 23. Since the side of the guide plate 1 22 and the top of the guide plate 2 23 are provided with an arc-shaped guide plate 3 24 spanning the top of the guide plate 2 23, some water contained in the gas is blocked by the arc-shaped guide plate 3 24 and falls into the water, and the clean gas rises toward the upper fan box 2 of the water bath box 1 until it passes through the fan box 2 and is discharged from the outlet pipe 4.

[0032] A roller 26 is provided at the bottom of the water bath box 1 , and a door 16 is provided on a side of the water bath box 1 away from the air inlet pipe 3 . A sealing strip is provided at the edge of the door 16 .

[0033] The device can be moved to a position where air purification is required by the roller 26, and after the air is purified, the water bath box 1 can be opened through the box door 16 to facilitate cleaning and maintenance inside it. The sealing strip at the edge of the box door 16 can ensure the sealing of the inside of the water bath box 1 to prevent water leakage.

[0034] The bottom of the water bath box 1 is tilted, and the water bath box 1 is provided with a collection bin 25 below the box door 16. The water bath box 1 is connected to the collection bin 25. A water pipe 18 is provided on one side of the collection bin 25, and a water valve is provided on the water pipe 18. A removable baffle 17 is provided on the top of the collection bin 25, and a sealing layer is provided at the edge of the baffle 17.

[0035] When the purification is completed, the magnetism of the electromagnetic plate 19 disappears, and the metal dust adsorbed on the electromagnetic plate 19 is separated from the electromagnetic plate 19. By opening the water valve on the water pipe 18, the water at the bottom of the water bath box 1 will flow toward the water pipe 18 due to the inclination of the bottom. The dust and metal dust will be discharged through the water pipe 18, but the rest will remain in the collection bin 25. By opening the baffle 17 on the top of the collection bin 25, the dust and metal dust inside the collection bin 25 can be completely cleaned to avoid clogging the water pipe 18 or corrosion of the device.

[0036] Example 2 Based on the first embodiment, an opening is provided on one side of the fan housing 2, an activated carbon adsorption layer 10 is inserted into the opening, the activated carbon adsorption layer 10 is located above the motor 14, and a handle 15 is provided at one end of the opening of the activated carbon adsorption layer 10.

[0037] Since the dust is purified by a water bath, a small amount of water vapor will be discharged along with the gas discharged from the outlet pipe 4. After the discharged water vapor condenses on the surface of the equipment, it may cause corrosion of metal parts. In addition, the water vapor enters the interior of the electrical equipment, which may cause a short circuit or a decrease in insulation performance, affecting the normal operation of the equipment. By providing an opening on one side of the fan case 2 and providing an activated carbon adsorption layer 10 at the opening, a small amount of water vapor in the gas after the water bath can be adsorbed to ensure the dryness of the discharged gas. By providing a handle 15 on one side of the activated carbon adsorption layer 10, it is convenient for the operator to quickly install or remove it, and it is convenient to remove the activated carbon adsorption layer 10 for drying after purification, which is convenient for subsequent purification work.

The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
