Description

Technical Field

[0001] This invention belongs to the field of construction dust removal technology, and in particular relates to a dust filtration device based on green construction. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, dust pollution during construction has become increasingly prominent. Dust not only poses a serious threat to the health of construction workers, but also pollutes the surrounding environment and affects air quality. Therefore, corresponding filtration devices are installed during construction to filter the dust generated during the construction process.

[0003] A patent application with publication number CN120242653A discloses a dust filtration device for road engineering based on green construction. The device includes a filter box with an air inlet at the front and an air outlet at the rear. It also includes a filtration unit. Dust enters the filter box through the air inlet and exits through the air outlet. When dust is in the filter box, it passes through a filter cartridge. A servo motor, drive disc, guide plate, and scraper scrape off dust particles adhering to the inside of the filter cartridge. Simultaneously, an extraction pipe draws out dust impurities, preventing them from accumulating on the outer wall of the filter cartridge and reducing its filtration efficiency. A crank, impact rod, and absorption plate shake off large dust particles from the surface, preventing excessive dust accumulation and filter cartridge blockage.

[0004] The above-mentioned technical solution uses a spray pipe at the air inlet to spray dust when filtering dust, followed by filtration using filter plates and filter cartridges. The defects of this method are particularly obvious: after the dust is moistened by the spray, the uncaptured damp dust is very easy to adhere to the surface of the filter plate or filter cartridge during the subsequent filtration process, forming caking, which leads to filter hole blockage, increased ventilation resistance, and a rapid decrease in filtration efficiency, resulting in a deterioration of the overall filtration effect.

[0037] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1 Please see Figures 1-9This invention relates to a dust filtration device based on green construction, comprising a drive base 1, a filter box 2 mounted on the drive base 1, an air collecting hood 3 connected to one side of the filter box 2, a suction fan 4 located on the other side of the filter box 2, a diversion pipe 5 connected to the suction fan 4 near the filter box 2, a flow valve 6 sleeved on the surface of the diversion pipe 5, a filtration mechanism 7 disposed inside the filter box 2, the filtration mechanism 7 comprising support plates 71 respectively disposed on the front and rear sides inside the filter box 2, a filter plate 72 installed between the two support plates 71, an anti-clogging component 73 disposed on one side of the filter plate 72, an adjustment component 74 disposed on the other side of the filter plate 72, and a spraying mechanism 8 disposed on one side of the diversion pipe 5, the spraying mechanism 8 comprising a spraying component installed at the bottom inside the filter box 2. The system includes a fixed cylinder 81, a spray pipe 82 located at the top of the fixed cylinder 81, a water tank 83 installed at the bottom of the filter box 2, a pressure pump 84 connected to the rear side of the water tank 83, a conduit 85 connected to the rear side of the pressure pump 84, a movable pipe 86 rotatably connected to the surface of the conduit 85, a filter screen 87 installed inside the water tank 83, a fixed shell 88 installed on the side of the filter plate 72 near the fixed cylinder 81, a horizontal pipe 89 connected to the side of the fixed cylinder 81 near the fixed shell 88, a ventilation pipe 810 connected to the side of the fixed shell 88 near the fixed cylinder 81, and guide ports 811 respectively opened at the bottom of the filter box 2 and the top of the water tank 83. The bottom of the suction fan 4 is fixedly connected to a support, and the suction fan 4 is installed on one side of the filter box 2 through the support.

[0039] The drive base 1 is used to support the entire device and drive it to move on the construction site, improving the mobility and operating range of the equipment. The filter box 2 serves as the main container for dust filtration, and contains the filter mechanism 7, spray mechanism 8, and other structures to achieve centralized dust treatment. The air collection hood 3 collects dust-laden air from the construction environment and guides it into the filter box 2 for filtration.

[0040] The exhaust end of the suction fan 4 is equipped with a dustproof screen. The suction fan 4 provides negative pressure suction, driving the dust-laden air from the air collection hood 3 into the filter box 2, and exhausting the filtered clean air. The end of the diversion pipe 5 away from the suction fan 4 extends into the interior of the filter box 2 and connects to the top of the fixed cylinder 81. The diversion pipe 5 is fixedly connected to the filter box 2. The diversion pipe 5 guides the airflow to the spray mechanism 8, adjusts the airflow distribution, and optimizes the spray dust removal effect. The flow valve 6 adjusts the airflow in the diversion pipe 5, controls the air intake of the spray area, and avoids affecting the filtration efficiency.

[0041] The support plate 71 is in close contact with the filter box 2. The filter plate 72 is designed to be inclined. The inclined setting of the filter plate 72 makes it easier for dust to slide down under the action of gravity, reducing adhesion and improving filtration efficiency and self-cleaning ability. The fixed cylinder 81 houses the spray pipe 82 and serves as an airflow channel in the spray area, enhancing the contact time between water and dust. The spray pipe 82 sprays water to capture fine dust, realizing secondary wet dust removal. One side of the water tank 83 is connected to the liquid inlet pipe, and the bottom of the water tank 83 is connected to the liquid outlet pipe. Both the liquid inlet pipe and the liquid outlet pipe are threaded with pipe caps. The water tank 83 stores the spray water and recovers and purifies the spray wastewater through the filter screen 87, realizing the recycling of water resources.

[0042] The pressure pump 84 is mounted on a mounting base on top and is installed on the rear side of the water tank 83 via the mounting base. The pressure pump 84 provides water pressure to the spray system to ensure the spraying effect. The filter screen 87 filters and recovers particulate matter in the water to prevent the spray system from clogging. The end of the conduit 85 away from the pressure pump 84 extends into the interior of the housing 731. The movable pipe 86 is rotatably connected to the surface of the conduit 85 via a bearing. The top of the movable pipe 86 is located inside the housing 731, and its bottom extends into the interior of the fixed cylinder 81 and communicates with the spray pipe 82. The movable pipe 86 is in close contact with both the filter box 2 and the fixed cylinder 81. The fixed shell 88 covers the area of ​​the filter plate 72 and guides the airflow into the spraying area to prevent dust from directly penetrating the filter plate 72 and spreading. The horizontal pipe 89 is sleeved on the surface of the ventilation pipe 810 and is in close contact with the ventilation pipe 810. The guide port 811 guides the wastewater after spraying back to the water tank 83 to realize the recycling of water.

[0043] During operation, the drive unit 1 drives the entire equipment to move within the construction site. The suction fan 4 operates, and dusty air enters through the air collection hood 3. Under the action of the inclined filter plate 72, the dust is blocked and filtered, and deposited at the bottom of the filter box 2 under the action of gravity. Because the filter plate 72 is designed to be inclined, the dust is more likely to fall off after being filtered by the filter plate 72, reducing the adhesion on the surface of the filter plate 72. The small amount of dust that is not captured enters the fixed cylinder 81 with the air through the fixed shell 88, ventilation pipe 810 and horizontal pipe 89, causing the pressure pump 84 to operate. Water in the water tank 83 is sprayed out from the spray pipe 82 through the conduit 85 and movable pipe 86, thereby removing the small amount of dust in the air. Since the area where the suction fan 4 generates negative pressure is located at the top of the fixed cylinder 81, the contact time between the dust and water increases when the air rises, so that the dust in the air is fully removed. Clean air is discharged from the exhaust end of the suction fan 4, thereby avoiding the adhesion of damp dust and improving the dust filtration effect.

[0044] When the spray pipe 82 is working, the suction force generated by the suction fan 4 is adjusted by the flow valve 6 to ensure that the dusty air is drawn in normally, but without affecting the spray dust removal. The water after spraying is filtered by the filter screen 87 through the guide port 811 and then enters the water tank 83 for reuse. The water in the water tank 83 is replaced periodically through the liquid inlet pipe and the liquid outlet pipe.

[0045] Example 2 Please see Figures 2-7 Based on Embodiment 1, the anti-clogging component 73 includes a housing 731 installed on the top of the filter box 2, a protective filter cartridge 732 installed on the top of the housing 731, a motor 733 installed inside the top of the protective filter cartridge 732 with its output end extending into the interior of the housing 731, a drive rod 734 installed at the output end of the motor 733, a rotating rod 735 rotatably connected to the front and rear sides of the filter box 2 with its bottom end extending into the interior of the filter box 2, an eccentric wheel 736 installed on the surface of the rotating rod 735, a connecting frame 737 disposed on the side of the eccentric wheel 736 near the support plate 71, a fixing plate 738 disposed on the side of the connecting frame 737 near the support plate 71, and a mounting plate 738 disposed on the side of the fixing plate 738 near the connecting frame 737. A support cylinder 739 on one side, a spring 7310 installed inside the support cylinder 739 near the connecting frame 737, a movable frame 7311 installed on the side of the spring 7310 near the connecting frame 737, and clearance grooves 7312 respectively opened on the front and rear sides inside the filter box 2. The top and bottom of the movable frame 7311 are equipped with sliders, which are slidably connected to the support cylinder 739. The top and bottom of the support cylinder 739 are provided with sliding grooves that are adapted to the sliders. The connecting frame 737 is in contact with the eccentric wheel 736. The side of the movable frame 7311 away from the spring 7310 extends through to the side of the support cylinder 739 near the connecting frame 737 and is installed on the side of the connecting frame 737 away from the eccentric wheel 736.

[0046] The output end of motor 733 is rotatably connected to housing 731 via bearing. Motor 733 provides power to drive drive rod 734 to rotate, thereby driving anti-clogging component 73 to work. Drive rod 734 transmits power to rotating rod 735 and movable tube 86 via synchronous belt drive. The bottom of drive rod 734 is rotatably connected to the top of filter box 2 via bearing. The top and bottom of rotating rod 735 are rotatably connected to filter box 2 via bearing. Synchronous pulleys are fixedly connected to the surfaces of drive rod 734, rotating rod 735, and movable tube 86. Synchronous pulleys on the surfaces of drive rod 734 and movable rod 735, as well as between drive rod 734 and rotating rod 735, are also fixedly connected to the surfaces of the movable tube 86. The synchronous pulleys on surface 35 are all connected by synchronous belt drive. The synchronous pulleys drive the synchronous pulleys through tooth meshing. The synchronous pulleys, synchronous belts, and the drive between them are all existing mature technologies, which will not be described in detail here. The eccentric wheel 736 rotates with the rotating rod 735, generating periodic reciprocating motion, which drives the connecting frame 737 to vibrate. The connecting frame 737 is in close contact with the eccentric wheel 736. The connecting frame 737 is installed on the support plate 71 near the side of the eccentric wheel 736. The fixing plate 738 is installed inside the filter box 2. The connecting frame 737 transmits the motion of the eccentric wheel 736 to the support plate 71, causing the filter plate 72 to vibrate.

[0047] During operation, when the filter plate 72 is filtering, the motor 733 drives the drive rod 734 to rotate, which in turn drives the rotating rod 735 to rotate via the synchronous pulley and synchronous belt. The eccentric wheel 736 presses against the connecting frame 737, and the support plate 71 drives the filter plate 72 to vibrate horizontally and reciprocally. This shakes off the dust adhering to the surface of the filter plate 72 during filtration, preventing blockage, ensuring airflow, and further improving the filtration effect. When the drive rod 734 rotates, it also drives the movable pipe 86 and the spray pipe 82 to rotate via the synchronous pulley and synchronous belt, increasing the spray range and ensuring the dust removal effect of spraying.

The third gear 7412 and the fourth gear 74111 mesh with each other, and the first gear 7410 and the second gear 7411 mesh with each other.

[0049] The connecting rod 743 is rotatably connected to the top of the reset cylinder 742 via a bearing. The torsion spring 745 is located on the surface of the connecting rod 743 and is in an energy storage state. The sealing cylinder 744 is located on the surface of the reset cylinder 742 and is in close contact with the reset cylinder 742. At the same time, the top of the sealing cylinder 744 is designed with an arc surface to avoid dust accumulation. The bottom of the conical frame 746 is installed on the side of the guide hood 747 away from the filter plate 72. The guide hood 747 is connected to the air collecting hood 3. The connecting section between the guide hood 747 and the air collecting hood 3 is made of soft elastic rubber. The bottom of the extrusion rod 748 is designed with a spherical shape and is in close contact with the conical frame 746.

[0050] The first gear 7410 is mounted on the surface of the drive rod 734. The movable rod 749 and the reciprocating screw 7418 are rotatably connected to the filter box 2 and the top of the box body 731 via bearings. The third gear 7412 is designed centrally and is located on the surface of the movable rod 749. The bottom of the movable block 7417 is slidably connected to the top of the filter box 2. The top of the filter box 2 has a movable groove that matches the movable block 7417. The limiting plate 74110 is slidably connected to the box body 731.

The fourth gear 74111 is mounted on the smooth section of the reciprocating screw 7418. The bottom of the fixing bracket 74112 extends into the inside of the filter box 2 and is mounted on the top of the extrusion rod 748. The fixing bracket 74112 is in close contact with the filter box 2.

[0051] Support cylinder 739 and spring 7310 provide elastic support, enhance vibration amplitude, and act as a buffer to protect structural stability. Movable frame 7311 and slider slide within support cylinder 739 to ensure stable vibration direction and prevent deviation. Eccentric wheel 736 in clearance groove 7312 provides movement space and avoids interference with the inner wall of filter box 2. Horizontal plate 741 and reset cylinder 742 support sealing cylinder 744 and conical frame 746. Torsion spring 745 is installed inside reset cylinder 742 to provide reset torque. Sealing cylinder 744 resets under the action of torsion spring 745, maintaining the initial position of guide shroud 747. The guide shroud 747 is adjustable in angle, changing the position of the airflow directly blowing onto the filter plate 72, avoiding local blockage, and improving the utilization efficiency of the filter plate 72. The extrusion rod 748 pushes the conical frame 746 to rotate, realizing the angle adjustment of the guide shroud 747. The movable rod 749 transmits the power of the drive rod 734 to the reciprocating screw 7418 through transmission, realizing automatic adjustment. The reciprocating screw 7418 and the ball nut sleeve 7419 convert the rotational motion into linear motion, pushing the extrusion rod 748 to move up and down. The electric telescopic rod 7413 and the limit rod 7414 realize the start and stop of the adjustment component 74.

[0052] During operation, dust-laden air drawn in from the three collection hoods is guided by the guide hood 747 and blown toward the filter plate 72. Periodically, the electric telescopic rod 7413 operates, causing the limiting rod 7414 to insert into the limiting groove 7415. When the drive rod 734 rotates, it drives the second gear 7411 to rotate via the first gear 7410. Through the limiting rod 7414, the electric telescopic rod 7413, and the third gear 7412, the fourth gear 74111 rotates. The fourth gear 74111 drives the reciprocating screw 7418 to rotate, causing the ball nut sleeve 7419 to move. When sleeve 7419 moves upward, torsion spring 745 resets, causing sealing cylinder 744, conical frame 746, and guide shroud 747 to rotate backward. When ball nut sleeve 7419 moves downward, it squeezes conical frame 746, causing guide shroud 747 to rotate forward. This adjusts the position of the direct blowing surface of guide shroud 747 on filter plate 72, preventing direct blowing to only one position and causing filter plate 72 to become clogged. The replacement of the direct blowing surface can provide space for vibration cleaning of filter plate 72, further improving the filtration effect. After adjustment, the electric telescopic rod 7413 resets, releasing the limit on second gear 7411.

[0053] Example 4 Please see Figure 1 Based on Examples 1 to 3, an observation window 9 is provided on the front side of the filter box 2, and a sealing plate 10 is installed on the surface of the observation window 9. The sealing plate 10 is installed on the front side of the filter box 2 by the first bolt.

[0054] The observation window 9 allows users to easily observe the bending state of the air guide 747, and the sealing plate 10 allows users to easily open the filter box 2 to clean the air guide 747.

[0055] Example 5 Please see Figures 1-4 Based on Examples 1 to 4, a collection shell 11 is installed on the bottom of the filter box 2 away from the air collecting hood 3 by a second bolt, and a material guide hood 12 is installed inside the collection shell 11.

[0056] The top of the guide hood 12 has an arc-shaped surface design, and the bottom has a conical opening design. The top is in close contact with the filter plate 72, the support plate 71, and the fixed shell 88. When the filter plate 72 is filtering, the dust will be deposited in the collection shell 11 under the action of gravity through the guide hood 12. The dust shaken off during vibration will be deposited at the contact position between the top of the guide hood 12 and the filter plate 72. During vibration, the dust at this point will be continuously pushed into the collection shell 11 through the guide hood 12 by the filter plate 72 and the support plate 71. The collected dust can be cleaned by periodically disassembling the collection shell 11.

[0057] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
