Chemical production equipment is prone to generate dust when in use, and the commonly used water spraying range is small, the dust absorption is not comprehensive, and the direct discharge of atomized water used for dust removal will cause a certain waste of resources; b. Sewage is easy to cause blockage of components in the water pump and dust removal system in the entire circulation system; c. The filter holes of the filter assembly are prone to blockage after long-term filtration, and manual disassembly and cleaning is not only labor-intensive, but also requires the suspension of the production line, affecting production capacity; d. The space after dust removal by the dust removal system is in a humid state, which has a certain impact on the use of the equipment.

[0082] Embodiment 3:

[0083] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.

[0084] like Figure 1-Figure 10 As shown, this embodiment provides a chemical production safety dust reduction device, including a frame 6, a partition 7 for supporting the production equipment is provided at the bottom of the frame 6, a plurality of drainage holes 3 distributed at equal distances are opened on the top of the partition 7, a dust removal system 1 for reducing dust is provided on the top of the frame 6, a water collecting box 5 is provided at the bottom of the partition 7, a water circulation system 4 connected to the dust removal system 1 is provided on one side of the water collecting box 5, a filter component 38 for filtering sewage is provided in the water collecting box 5, a self-cleaning component for cleaning the filter component 38 is provided on the outside of the water collecting box 5, and a fresh air system 2 for dehumidifying the space where the production equipment is located after dust reduction is provided on both sides of the frame 6.

After filtration, the filter holes are prone to clogging, and manual disassembly and cleaning is not only labor-intensive, but also requires the suspension of the production line, affecting production capacity. Therefore, a self-cleaning component is used to enable the filter component 38 to be automatically cleaned, thereby effectively improving productivity. The space after dust removal by the dust removal system 1 is in a humid state, so a fresh air system 2 is used to dehumidify and exchange air for the internal space of the frame 6, thereby achieving effective protection of the chemical production equipment. Two slopes 10 are provided on the top of the partition 7, and the lowest points of the two slopes 10 are opposite, and the lowest point is located in the middle position of the partition 7, so that water can gather along the slope 10 to the middle position of the partition 7 through its own gravity, thereby effectively avoiding water accumulation above the partition 7.

[0086] In order to solve the problem that chemical production equipment is prone to generate dust when in use and the direct discharge of atomized water used for dust removal will cause a certain amount of waste of resources, the dust removal system 1 in this embodiment includes a plurality of guide rails 14, and the plurality of guide rails 14 are respectively installed on the inner walls of both sides of the frame 6 through vertical fixed seats, and a slide 13 is slidably connected to one side of the guide rail 14, and a connecting frame 18 is fixed between the plurality of slides 13 by bolts, and a plurality of drainage pipes 24 are fixed to the bottom of the connecting frame 18 by bolts, and a plurality of rotating seats 27 distributed at equal distances are rotatably connected to the bottom of the drainage pipe 24, and two branch pipes 29 are arranged at the bottom of the rotating seat 27, and an atomizing nozzle 28 is arranged at the bottom end of the branch pipe 29, and a side of the frame 6 is provided with a nozzle 28 for enabling the atomizing nozzle 28 to be The driving mechanism for uniform water spraying includes a plurality of pull ropes 25, which are respectively fixed between the diagonals of two adjacent rotating seats 27. A reset torsion spring 26 is provided on one side of the rotating seat 27, and the two ends of the reset torsion spring 26 are respectively fixed to the drainage pipe 24 and the rotating seat 27. A force rod 21 is fixed to one side of one rotating seat 27 by bolts, and a plurality of levers 23 corresponding to the force rod 21 are fixed to the inside of the top two sides of the frame body 6 by bolts. A servo motor 15 is fixed to the outer wall of one side of the frame body 6 by bolts, and a turntable 16 is fixed to one end of the output shaft of the servo motor 15 by bolts. The top of the turntable 16 is rotatably connected to a connecting rod 17, and one end of the connecting rod 17 is rotatably connected to a connecting frame 18.

[0087] When in use, water is passed through the water circulation system 4 to enter the branch pipe 29 through the drainage pipe 24 and is sprayed from the atomizing nozzle 28. Then, by starting the servo motor 15, the servo motor 15 rotates to make the turntable 16 drive the connecting frame 18 and the slide 13 to reciprocate along the guide rail 14 through the connecting rod 17, thereby preliminarily improving the spraying range of the atomizing nozzle 28. While the connecting frame 18 reciprocates, the force rod 21 intermittently contacts the lever 23. At this time, the force rod 21 is forced to drive the rotating seat 27 to rotate. When the rotating seat 27 located in the first position rotates, the pull rope 25 arranged diagonally makes the rotating seats 27 at adjacent positions rotate in the opposite direction. Then, the rotating seat 27 after rotation is reversely rotated and reset by the reset torsion spring 26. The mist sprayed by the adjacent atomizing nozzles 28 can hit each other and form a finer water mist, thereby further improving the spraying range and the fineness of the water mist of the atomizing nozzle 28, so that the atomized water can contact the dust in the air more comprehensively.

[0088] In order to solve the problem that sewage easily causes blockage of components in the water pump 41 and the dust removal system 1 in the entire circulation system, the water circulation system 4 in this embodiment includes a water pump 41, which is fixed to one side of the frame 6 by bolts, and one end of the water outlet of the water pump 41 is fixed with an inlet pipe 20 by bolts, and one side of the water inlet pipe 20 is connected with multiple drainage pipes 24 through multiple hoses 19 respectively, and the filter components 38 are connected through a connecting pipe 39, one end of the connecting pipe 39 passes through the water collecting tank 5 and is welded with a sedimentation ball 40, and the top side of the sedimentation ball 40 is fixed to one end of the water inlet of the water pump 41 through an overflow pipe, and the filter component 38 is a plurality of outer filter cartridges 44, and the plurality of outer filter cartridges 44 are evenly arranged inside the water collecting tank 5.

[0089] When in use, by starting the water pump 41, the water pump 41 rotates to allow the water collected in the water collecting box 5 to pass through the filter assembly 38 and the sedimentation ball 40 and enter the water inlet pipe 20, and then enter the dust removal system 1 through the water inlet pipe 20.

[0090] In order to solve the problem that the filter holes 45 are easily blocked after long-term filtration, manual disassembly and cleaning is not only labor-intensive, but also requires the suspension of the production line, affecting production capacity. The self-cleaning component in this embodiment includes an inner filter frame 42, which is rotatably connected to the inside of an outer filter cartridge 44. The outer side of the outer filter cartridge 44 is provided with a plurality of filter holes 45 distributed at equal distances, and the inside of the filter holes 45 is provided with an inner conical surface 46. Through holes 48 distributed at equal distances are provided on multiple sides of the inner filter frame 42, and the through holes 48 correspond to the filter holes 45. A top ball 47 that can move up and down along the inner wall of the through hole 48 is provided in the through hole 48, and the top ball 47 can contact the inner conical surface 46. The top of the top ball 47 is a smooth surface 51, and a top rod 49 is welded to the bottom of the top ball 47. A tension spring 50 is fixed to one end of the top rod 49 by bolts, and the other end of the tension spring 50 is fixed to the inner filter frame 42. One end of the inner filter frame 42 is welded There is a rotating shaft 43, one end of which passes through the outer filter cartridge 44 and the water collecting box 5 and is keyed to a gear 34. One side of the frame body 6 is slidably connected to a force frame 31 through a plurality of vertical slides 32. The bottom of the force frame 31 is fixed with a plurality of racks 33 that are respectively meshed with a plurality of gears 34 by bolts. A guide reset mechanism is provided between the force frame 31 and the frame body 6. A slope 30 is provided on the top of the force frame 31. A pressure frame 22 is fixed with bolts on one side of the connecting frame 18, and the pressure frame 22 can contact the slope 30 provided on the force frame 31. The guide reset mechanism includes two guide rods 37. The two guide rods 37 are fixed to one side of the frame body 6 by bolts. One side of the force frame 31 is fixed with two guide cylinders 36 that are plugged into the guide rods 37 by bolts. A reset spring 35 is fixed between the guide cylinder 36 and the frame body 6 by bolts. The reset spring 35 realizes the upward movement and reset of the force frame 31.

[0091] When in use, double filtration is achieved through the inner filter frame 42 and the outer filter cartridge 44. Then, when the connecting frame 18 is reciprocating, it will intermittently drive the pressing frame 22 to contact the inclined surface 30 opened on the top of the force-bearing frame 31, and squeeze the force-bearing frame 31 through the inclined surface 30. At this time, the force-bearing frame 31 drives the rack 33 to move downward. After the rack 33 moves downward, it drives the gear 34 to rotate. The rotation of the gear 34 causes the rotating shaft 43 to drive the inner filter frame 42 to rotate. At this time, the inner filter frame 42 and the outer filter cartridge 44 are rotated and misaligned. Then, when the top ball 47 moves to the position of the inner conical surface 46 of the filter hole 45, the pull The spring 50 shortens and resets, so that the push rod 49 drives the push ball 47 to move quickly out of the through hole 48. At this time, the water flow impact force generated by the movement of the push ball 47 flushes the dirt blocking the filter hole 45, and when the push ball 47 is in full contact with the inner conical surface 46, the dirt blocking the filter hole 45 is further ejected. Under this dual action, the cleaning effect is improved. When the inner filter frame 42 continues to rotate, the smooth surface 51 separates the push ball 47 from the inner conical surface 46 and squeezes the push ball 47 back into the through hole 48. This reciprocating cycle is repeated to achieve rapid cleaning of the filter hole 45.

[0092] In order to solve the problem that the space is in a humid state after dust removal by the dust removal system 1, which has a certain impact on the use of the equipment, the fresh air system 2 in this embodiment includes a plurality of blowing fan mounting frames 12, and the plurality of blowing fan mounting frames 12 are respectively fixed to the outer walls on both sides of the frame body 6 by bolts, and the bottom ends of the plurality of blowing fan mounting frames 12 are fixed with hot blowing fans 11 by bolts, and the top outer wall of the frame body 6 is fixed with two exhaust fan mounting frames 9 by bolts, and one end of the two exhaust fan mounting frames 9 is fixed with normal temperature exhaust fans 8 by bolts.

[0093] When in use, by starting the hot blowing fan 11, the hot blowing fan 11 rotates to generate hot air and dry and dehumidify the air inside the frame 6 and the chemical production equipment. At this time, the hot air temperature is relatively high, and its volume expands after being heated, its density decreases, and its weight becomes lighter, so the hot air will flow upward. At the same time, by starting the normal temperature exhaust fan 8, the normal temperature exhaust fan 8 rotates to accelerate the air flow, thereby realizing wind circulation, further improving the dehumidification effect of the space where the production equipment is located after dust reduction.

[0094] Working principle of this embodiment:

[0095] When in use, first build a frame 6 around the chemical production equipment, and make the chemical production equipment located above the partition 7. At this time, by starting the water pump 41, the water pump 41 rotates to make the water collected in the water collection tank 5 pass through the filter assembly 38 and the sedimentation ball 40 and enter the water inlet pipe 20, and then enter the drainage pipe 24 through the water inlet pipe 20. Then the water enters the branch pipe 29 through the drainage pipe 24 and is sprayed out from the atomizing nozzle 28. Then, by starting the servo motor 15, the servo motor 15 rotates to make the turntable 16 drive the connecting frame 18 and the slide 13 to reciprocate along the guide rail 14 through the connecting rod 17, thereby preliminarily improving the spray range of the atomizing nozzle 28. While the connecting frame 18 reciprocates, the force rod 21 intermittently contacts the lever 23. When the force-bearing rod 21 is driven by the force to drive the rotating seat 27 to rotate, when the rotating seat 27 at the first position rotates, the pull rope 25 arranged diagonally causes the rotating seats 27 at different positions to rotate, and then the rotating seat 27 after rotation is reversely rotated and reset by the reset torsion spring 26, thereby further improving the spraying range of the atomizing nozzle 28, making the atomized water contact with the dust in the air more comprehensive, and connecting the collected water with the dust removal system 1 through the water circulation system 4 to realize water recycling. At this time, the filter component 38 is used to filter the sewage in the water collection tank 5, so that the filtered sewage enters the water circulation system 4, and double filtration is realized through the inner filter frame 42 and the outer filter cartridge 44, and then the connecting frame 18 will intermittently bring the dust in the water collection tank 5 when it moves back and forth. The dynamic pressure frame 22 contacts the inclined surface 30 opened on the top of the force-bearing frame 31, and squeezes the force-bearing frame 31 through the inclined surface 30. At this time, the force-bearing frame 31 drives the rack 33 to move downward. After the rack 33 moves downward, it drives the gear 34 to rotate. The rotation of the gear 34 causes the rotating shaft 43 to drive the inner filter frame 42 to rotate. Then, when the top ball 47 moves to the position of the inner conical surface 46 of the filter hole 45, the tension spring 50 shortens and resets, so that the top rod 49 drives the top ball 47 to move quickly out of the through hole 48. At this time, the water flow impact force generated by the movement of the top ball 47 flushes the dirt blocked in the filter hole 45, and when the top ball 47 is completely in contact with the inner conical surface 46, the dirt blocked in the filter hole 45 is further ejected. Under this dual action, the cleaning effect is improved, and the inner filter frame 42 continues to rotate. When the top ball 47 is separated from the inner conical surface 46 by the smooth surface 51, and the top ball 47 is squeezed into the through hole 48 again, and the reciprocating cycle is repeated, so that the filter hole 45 can be quickly cleaned. Therefore, a self-cleaning component is used to enable the filter component 38 to be automatically cleaned, thereby effectively improving productivity. At the same time, by starting the hot blowing fan 11, the hot blowing fan 11 rotates to generate hot air and dry and dehumidify the air inside the frame 6 and the chemical production equipment. At this time, the hot air has a high temperature, and its volume expands after being heated, its density decreases, and its weight becomes lighter. Therefore, the hot air will flow upward. At the same time, by starting the normal temperature exhaust fan 8, the normal temperature exhaust fan 8 rotates to accelerate the air flow, thereby realizing wind circulation, and further improving the dehumidification effect of the space where the production equipment is located after dust reduction.Thereby achieving effective protection of chemical production equipment.

[0096] The electrical components mentioned above are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0097] The present invention adopts a dust removal system to perform effective dust removal and collects sewage through a water collecting tank, and then connects the collected water to the dust removal system through a water circulation system to realize water recycling, and adopts a self-cleaning component to enable the filter component to be automatically cleaned, thereby effectively improving productivity, and adopts a fresh air system to dehumidify and exchange air in the space inside the frame, thereby realizing effective protection of chemical production equipment.
