An engineering environmental protection dust removal device

Abstract

This utility model discloses an environmentally friendly dust removal device for engineering, relating to the field of environmental engineering technology. The utility model includes a dust collection box, on which a dust removal mechanism and a spraying mechanism are installed. By incorporating the dust removal mechanism, when the drive motor rotates the shaft and impeller, the air inside the dust collection box is drawn to the outside in conjunction with the fan casing. When the dust suction hood end on the corrugated pipe is aligned with the area requiring dust removal, external air and dust are drawn into the dust suction hood. The air is then filtered by the filter blocks, removing dust. After prolonged use, pulling the two pads moves the sliding rod away from the slot on the dust suction hood, pulling the two springs and stretching them, allowing the filter blocks to be removed from the dust suction hood for replacement. This ensures long-term effective dust removal and filtration, significantly improving the overall lifespan of the device.

Description

Technical Field

[0001] This utility model belongs to the field of environmental protection engineering technology, and in particular relates to an engineering environmental dust removal device. Background Technology

[0002] Environmental protection refers to all actions taken by human beings to solve existing or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure the sustainable development of the economy and society. Its methods and means include engineering technology, administrative management, innovative research and development, as well as legal, economic, publicity and education, etc. In the construction industry, dust suppression spraying is often required to protect the construction environment.

[0003] Traditional dust removal equipment often struggles to accurately target the areas requiring dust removal, significantly reducing its effectiveness. Furthermore, its poor air filtration fails to effectively separate dust from air, resulting in exhaust air still containing a significant amount of impurities. Additionally, after prolonged use, filter components become difficult to disassemble and replace, and continued use reduces the dust removal and filtration efficiency, also impacting the overall lifespan of the equipment. Summary of the Invention

[0004] The purpose of this utility model is to provide an engineering environmental protection dust removal device, which solves the problem that traditional dust removal equipment often has difficulty in accurately targeting the location that needs dust removal, resulting in a significant reduction in dust removal effect. Moreover, its air filtration effect is poor, and it cannot effectively separate dust from air, resulting in the exhaust air still containing a lot of impurities. In addition, after long-term use, the filter components are not easy to disassemble and replace, and continued use will reduce the dust removal filtration effect and also affect the overall service life of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an engineering environmental protection dust removal device, including a dust collection box, on which a dust removal mechanism and a spraying mechanism are provided;

[0007] The dust removal mechanism includes two corrugated pipes respectively connected to the left and right sides of the dust collection box. Both corrugated pipes are fixedly connected to the dust collection box. A dust suction hood is connected to the end of each of the two corrugated pipes away from the dust collection box. Two sliding rods slide through each of the two dust suction hoods. Gaskets are fixedly connected to the outer walls of the four sliding rods. Springs are wound around the outer walls of the four sliding rods. One end of the spring is fixedly connected to the gasket, and the other end of the spring is fixedly connected to the dust suction hood. Filter blocks are slidably connected to the inner walls of the two dust suction hoods. Two slots that match the sliding rods are formed on each of the two filter blocks.

[0008] Furthermore, a fan housing is connected to the top of the dust collection box, and a motor is fixedly connected to the top of the fan housing. The output end of the motor is fixedly connected to a rotating shaft via a coupling.

[0009] Furthermore, an impeller is fixedly connected to the outer wall of the rotating shaft, and the impeller is located inside the fan casing.

[0010] Furthermore, the spraying mechanism includes a water storage tank fixedly connected to the rear side of the dust collection box, a liquid pump fixedly connected to the inner wall of the water storage tank, and a conduit fixedly connected to the output end of the liquid pump.

[0011] Furthermore, the end of the conduit away from the liquid pump extends into the interior of the dust collection box, the dust collection box is fixedly connected to the conduit, and an annular pipe is connected to the end of the conduit away from the liquid pump, the annular pipe is fixedly connected to the conduit.

[0012] Furthermore, the outer wall of the annular tube is connected to several nozzles, and the inner wall of the dust collection box is fixedly connected to a filter cartridge. The several nozzles are evenly distributed on the outer wall of the filter cartridge in a circumferential arrangement.

[0013] Furthermore, a drain pipe is connected to the bottom of the filter cartridge and is fixedly connected to the filter cartridge. A sewage pipe is connected to the top of the dust collection box and is fixedly connected to the dust collection box. Valves are installed on both the drain pipe and the sewage pipe.

[0014] Furthermore, the dust collection box has a hinged door on the front side, a sliding groove on the front side of the dust collection box, a return plate slidably connected to the inner wall of the sliding groove, a plurality of diversion grooves on the return plate, the return plate being located above the filter cartridge and below the fan housing.

[0015] This utility model has the following beneficial effects:

[0016] Equipped with a dust removal mechanism, the drive motor rotates the shaft and impeller, which, in conjunction with the fan casing, draws air from inside the dust collection box to the outside. When the dust suction hood on the corrugated pipe is aligned with the area requiring dust removal, outside air and dust are drawn into the hood. The filter blocks then filter the air, removing dust. After prolonged use, pulling the two pads moves the sliding rod away from the slot on the dust suction hood, pulling the two springs and stretching them. This allows the filter block to be removed from the dust suction hood for replacement, ensuring long-term effective dust removal and filtration, and significantly extending the overall lifespan of the device.

[0017] Equipped with a spray mechanism, after external air is introduced into the dust collection box, water is poured into the water storage tank and a liquid pump is driven to pump the water into the conduit. The water flows through the annular pipe and is then distributed to multiple nozzles to spray onto the outer wall of the filter cartridge, forming a water curtain on the outer wall of the filter cartridge. When external air is drawn to the fan casing through the water curtain, it can perform secondary dust removal and dust suppression treatment on the air, thereby further improving the dust removal effect of the overall device. The multiple diversion grooves on the return plate increase the resistance to air rising, causing water vapor in the air to condense on the diversion grooves and drip into the filter cartridge, which is then discharged through the drain pipe, preventing water vapor from escaping and ensuring the reliability of the overall device.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The dust removal mechanism 2 includes two corrugated pipes 21 respectively connected to the left and right sides of the dust collection box 1. Both corrugated pipes 21 are fixedly connected to the dust collection box 1. A dust suction hood 22 is connected to the end of each of the two corrugated pipes 21 away from the dust collection box 1. Two sliding rods 23 slide through each of the four dust suction hoods 22. Gaskets 24 are fixedly connected to the outer walls of each of the four sliding rods 23. Springs 25 are wound around the outer walls of each of the four sliding rods 23. One end of the spring 25 is fixedly connected to the gasket 24, and the other end of the spring 25 is fixedly connected to the dust suction hood 22. Filter blocks 26 are slidably connected to the inner walls of each of the two dust suction hoods 22. Each of the two filter blocks 26 has two slots that are adapted to the sliding rods 23. The top of the dust collection box 1 is connected to a fan housing 27. A motor 28 is fixedly connected to the top of the fan housing 27. The output end of the motor 28 is fixedly connected to a rotating shaft 29 via a coupling. An impeller 291 is fixedly connected to the outer wall of the rotating shaft 29. The impeller 291 is located inside the fan housing 27. With the dust removal mechanism 2, after the filter block 26 has been used for a long time, the two pads 24 are pulled. At this time, the slide rod 23 moves away from the slot on the dust collection hood 22, pulling the two springs 25, so that the two springs 25 are in a stretched state, thereby removing the filter block 26 from the inside of the dust collection hood 22 for replacement, ensuring a long-term effective dust removal and filtration effect, and greatly improving the service life of the overall device.

[0030] The spraying mechanism 3 includes a water tank 31 fixedly connected to the rear side of the dust collection box 1. A liquid pump 32 is fixedly connected to the inner wall of the water tank 31. A conduit 33 is fixedly connected to the output end of the liquid pump 32. One end of the conduit 33 away from the liquid pump 32 extends into the interior of the dust collection box 1. The dust collection box 1 is fixedly connected to the conduit 33. An annular pipe 34 is connected to the end of the conduit 33 away from the liquid pump 32. The annular pipe 34 is fixedly connected to the conduit 33. Several nozzles 35 are connected to the outer wall of the annular pipe 34. A filter cartridge 36 is fixedly connected to the inner wall of the dust collection box 1. Several nozzles 35 are evenly distributed in a circular arrangement on the outer wall of the filter cartridge 36. A drain pipe 37 is connected to the bottom of the filter cartridge 36. The drain pipe 37 is fixedly connected to the filter cartridge 36. A sewage pipe 38 is connected to the top of the dust collection box 1. The sewage pipe 38 is fixedly connected to the dust collection box 1. Both the drain pipe 37 and the sewage pipe 38 are equipped with valves 39. The front of the dust collection box 1 is hinged with a door 11. The front of the dust collection box 1 is provided with a sliding groove 12. The inner wall of the sliding groove 12 is slidably connected with a return plate 13. Several diversion grooves 14 are provided on the return plate 13. The return plate 13 is located above the filter cartridge 36 and below the fan housing 27. Water is poured into the water storage tank 31 by the spraying mechanism 3 and the liquid pump 32 is driven to pump the water into the conduit 33. After flowing through the annular pipe 34, the water is diverted to multiple nozzles 35 and sprayed to spray the outer wall of the filter cartridge 36, thereby forming a water curtain on the outer wall of the filter cartridge 36. When the outside air is drawn to the fan housing 27 through the water curtain, it can perform secondary dust removal and dust reduction treatment on the dust in the air, thereby further improving the dust removal effect of the overall device.

[0031] A specific application of this embodiment is as follows: By setting up a dust removal mechanism 2, when the drive motor 28 drives the rotating shaft 29 and impeller 291 to rotate, the air inside the dust collection box 1 can be drawn to the outside and discharged in conjunction with the fan housing 27. After the dust suction hood 22 end on the corrugated pipe 21 is aligned with the position that needs to be dusted, the outside air and dust can be drawn into the dust suction hood 22. Under the filtering action of the filter holes of the filter block 26, the air can be dusted. After the filter block 26 has been used for a long time, the two pads 24 are pulled. At this time, the slide rod 23 moves away from the slot on the dust suction hood 22, and pulls the two springs 25, so that the two springs 25 are in a stretched state, thereby removing the filter block 26 from the inside of the dust suction hood 22 for replacement, ensuring a long-term effective dust removal and filtration effect, and greatly improving the service life of the overall device.

[0032] By incorporating a spray mechanism 3, after introducing external air into the dust collection box 1, water is poured into the water storage tank 31 and the liquid pump 32 is driven to pump the water into the conduit 33. The water then flows through the annular pipe 34 and is distributed to multiple nozzles 35 to spray onto the outer wall of the filter cartridge 36, thereby forming a water curtain on the outer wall of the filter cartridge 36. When external air is drawn to the fan casing 27 through the water curtain, it can perform secondary dust removal and dust reduction treatment on the dust in the air, thereby further improving the dust removal effect of the overall device. Meanwhile, the multiple diversion grooves 14 on the return plate 13 increase the resistance to air rise, causing water vapor in the air to condense on the diversion grooves 14 and drip into the filter cartridge 36 and be discharged through the drain pipe 37, preventing water vapor from escaping and ensuring the reliability of the overall device.
