Description

Technical Field

[0001] The invention relates to the technical field of construction air dust removal, and in particular to an air dust removal device for environmental protection engineering construction. Background Art

[0002] The air dust removal device used in environmental protection engineering construction is a special equipment designed to effectively remove large particles, fine particles, toxic and harmful gases and other pollutants in the air at the construction site to reduce the impact on the surrounding environment and protect the health of construction workers.

[0003] After searching, the Chinese patent with announcement number CN213286101U discloses a dust removal device for construction, including a dust removal vehicle body, a roller and a push frame. A dust separation chamber is arranged in the dust removal vehicle body, a pipe groove is arranged on a side wall of one side of the dust separation chamber, and a dust suction mechanism extending to the outside of the dust removal vehicle body is connected in the pipe groove; a dust filter element is arranged in the dust separation chamber, and a fan and a blower both connected to the inside of the dust filter element are arranged on the dust removal vehicle body; a dust collecting box for collecting dust is detachably connected at the bottom of the dust separation chamber; a baffle for opening and closing the pipe groove is arranged in the dust removal vehicle body, an exhaust member is arranged on the side wall of the dust separation chamber, a filter plate is arranged on the exhaust member, and an end cover for opening and closing the exhaust member is detachably connected at one end of the exhaust member away from the dust separation chamber. The above scheme provides a dust removal device for construction, which can realize that after the dust removal is completed, the structure for filtering dust does not need to be replaced or disassembled, and can be directly cleaned, which is convenient for next use. However, the above scheme still has the following shortcomings when actually used: Although the above scheme provides the function of cleaning the filter element, in actual application, this scheme has the following significant disadvantages: First, the cleaning process requires suspending the operation of the machine, which directly affects the working efficiency of the device. In an industrial production environment, the dust removal device often needs to operate continuously to ensure the cleanliness and safety of the production environment. Suspending the machine for cleaning will not only cause production interruptions, but may also affect the overall production progress and efficiency, and increase production costs. Secondly, this scheme adopts the method of reverse blowing into the filter element for cleaning. This cleaning method has limitations. It is difficult to effectively remove the dust tightly attached to the surface of the filter element by jet cleaning alone. Under long-term use, a dust layer that is difficult to remove is easy to accumulate on the surface of the filter element, which gradually causes the filter element to become clogged. The filter element clogged will not only reduce the dust removal effect, but may also increase the operating load of the machine and shorten the service life of the filter element.

[0015] As a preferred technical solution of the present invention, the outer peripheral surface of the rotating disk is provided with anti-slip grooves, and the damping rod is made of rubber material.

[0016] The present invention has the following beneficial effects: 1. When the present invention is in use, the cleaning mechanism uses a rod-shaped handle to push the horizontal plate to move, thereby driving the dust cleaning plate to move on the dust filter plate. The dust cleaning plate applies pressure on the surface of the dust filter plate to effectively push the dust to move toward the sewage outlet. The design of the torsion spring ensures that the dust cleaning plate has sufficient cleaning force during the movement. Through the automatic cleaning mechanism, the dust removal performance of the dust filter plate is restored, the service life of the filter plate is extended, and the need for frequent replacement of the dust filter plate is reduced, which not only reduces maintenance costs, but also provides convenience for staff; 2. The dust removal filter plate is soaked by water flow, and the dust will be mixed in the water flow and closely combined with the wet filter plate. The wet environment reduces the adhesion of dust on the surface of the filter plate, making it easier for the dust removal plate to remove dust from the surface of the filter plate when moving, effectively avoiding the accumulation of dust, thereby significantly improving the dust cleaning effect of the dust removal plate; 3. When the staff controls the horizontal plate to reset, the cleaning plate will contact the dust filter plate again and rest on the filter plate. Due to the obstruction of the dust filter plate, the cleaning plate will rotate in the opposite direction. During this process, the cleaning plate will not apply additional force to the torsion spring, and the reaction force of the torsion spring will not act on the cleaning plate. This design cleverly avoids the cleaning plate from applying unnecessary pressure to the dust filter plate during the reset process, thereby reducing the wear between the cleaning plate and the dust filter plate, and effectively extending the service life of the dust filter plate; 4. The device allows cleaning of a dust filter plate during the dust removal process without interrupting the entire dust removal process. By adjusting the position of the guide plate, the gas is guided to the other air outlet for discharge, ensuring the continuity of the dust removal work. This design not only improves work efficiency, but also avoids production interruptions caused by shutdown for cleaning; 5. Through the elastic force of the booster spring, the damping rod always keeps a tight state against the rotating disk. This design creates a large friction force between the damping rod and the rotating disk. This friction force can effectively prevent the rotating disk from accidentally rotating without human operation, thereby ensuring the position stability of the guide plate during the dust removal process.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-12 , an air dust removal device for environmental protection engineering construction, comprising an outer chassis 1, two dust filter plates 2, an air guide unit, a drive unit and a filter material regeneration unit, a first vertical plate 103 and a second vertical plate 104 are fixed inside the outer chassis 1, two partitions 105 are fixed between the first vertical plate 103 and the second vertical plate 104, and the two dust filter plates 2 are respectively located above the two partitions 105, and the air dust removal device for environmental protection engineering construction proposed by the present invention has two dust filter plates 2, when the device is used, the air guide unit guides the airflow, so that the dust-containing gas in the external environment is sprayed toward the dust filter plate 2 through the air outlet hood 36, in this process, the dust filter plate 2 can intercept the dust in the gas, and the clean gas will pass through the dust filter plate 2, so as to capture and collect the dust, and the bottom surface of the outer chassis 1 is installed with four universal wheels, so that the staff can flexibly arrange the position of the outer chassis 1; Reference Fig. 9The air guide unit is arranged inside the outer case 1 for guiding the airflow. The air guide unit includes two air outlet covers 36, which are respectively located above the two dust filter plates 2. The outer case 1 is provided with an air inlet 101 and two air outlets 102. The air guide unit includes an air inlet cover 31, a plurality of exhaust fans 32, a flow divider cover 33, two air supply cylinders 35 and two exhaust fans 39. The air inlet cover 31 is fixed on the first vertical plate 103, and the air inlet cover 31 is arranged opposite to the air inlet 101. The plurality of exhaust fans 32 are installed inside the air inlet cover 31. The flow divider cover 33 is arranged on the side of the second vertical plate 104. The flow divider cover 33 has an inlet. The air end and the two air outlet ends, the air inlet hood 31 and the air inlet end of the diverter hood 33 are connected through a first connecting pipe 34, the two air supply cylinders 35 are fixed on the side of the second vertical plate 104, the two air outlet ends of the diverter hood 33 are connected with a second connecting pipe 38, the two second connecting pipes 38 are connected with the two air supply cylinders 35 at one end away from the diverter hood 33, the two air supply cylinders 35 are respectively arranged opposite to the two air outlet hoods 36, each air supply cylinder 35 is connected to the corresponding air outlet hood 36 through a bellows 37, and the two exhaust fans 39 are installed on the second vertical plate 104, and the two exhaust fans 39 are respectively arranged opposite to the two air outlets 102; For the air guide unit, when the device is running, a plurality of exhaust fans 32 are synchronously operated to guide the airflow. Under the exhaust action of the plurality of exhaust fans 32, the ambient gas will be sucked into the air inlet hood 31 and enter the diverter hood 33 through the first connecting pipe 34. The diverter hood 33 has an air inlet end and two air outlet ends, and a guide plate 331 is also arranged inside the diverter hood 33. The staff can control the direction of the airflow in the diverter hood 33 by the position of the guide plate 331, such as Fig.10 As shown, in the initial state, the guide plate 331 guides the airflow to one of the air outlet ends, and enters the air supply cylinder 35 through the corresponding second connecting pipe 38. Further, the gas will enter the air outlet cover 36 through the bellows 37, and finally be ejected through the air outlet cover 36. Two exhaust fans 39 are installed on the second vertical plate 104, and the two exhaust fans 39 are respectively arranged opposite to the two dust filter plates 2. The airflow after passing through the dust filter plates 2 will be discharged from the inside of the outer chassis 1 under the guidance of the exhaust fans 39, and finally the gas in the construction environment is purified. The present invention designs two dust removal filter plates 2. When a worker needs to replace a dust removal filter plate 2, he only needs to adjust the position of the guide plate 331 to ensure that the other dust removal filter plate 2 continues to perform dust removal work, thereby ensuring the continuous progress of the production or processing process. This feature not only avoids production interruption and time loss caused by stopping to replace the filter plate, but also improves the overall work efficiency and equipment utilization. The continuously running dust removal system can more effectively control dust emissions and avoid dust removal window periods. Reference Fig.10 and Fig.11 A rotatable shaft 332 is mounted on the flow divider 33, one end of the shaft 332 extends to the outside of the flow divider 33, a guide plate 331 is fixed on the shaft 332, and the guide plate 331 is located inside the flow divider 33, and a rotating assembly is arranged on the outside of the flow divider 33, the rotating assembly includes a rotating disk 333, a side plate 334, an outer cylinder 335 and a damping rod 336, the rotating disk 333 is fixed to one end of the shaft 332 located outside the flow divider 33, and the rotating disk 333 and the shaft 332 are aligned. The outer cylinder 335 is fixed on the side of the shroud 33, and the outer cylinder 335 is fixed on the side of the shroud 33. The end of the outer cylinder 335 away from the side plate 334 is open. The damping rod 336 is movably inserted in the outer cylinder 335. One end of the damping rod 336 extends to the outside of the outer cylinder 335 and abuts against the rotating disk 333. The outer cylinder 335 and the damping rod 336 are connected by a booster spring 337. The outer peripheral surface of the rotating disk 333 is provided with anti-slip grooves, and the damping rod 336 is made of rubber material. When the staff controls the deflector 331 to rotate, the rotating disk 333 can be used to drive the rotating shaft 332 to rotate. An outer cylinder 335 and a damping rod 336 are provided below the rotating disk 333, and the outer cylinder 335 and the damping rod 336 are connected by a booster spring 337. Under the elastic force of the booster spring 337, the damping rod 336 is always in a state of pressing against the rotating disk 333, so that there is a large friction force between the damping rod 336 and the rotating disk 333, and the friction force can prevent the rotating disk 333 from rotating in an unintentional manner, thereby ensuring the position stability of the deflector 331 during the dust removal process. Reference Figure 4 The driving unit is arranged inside the outer case 1 and is used to drive the two air outlet covers 36 to move. The driving unit includes two push rods 41, a connecting frame 42 and a linear actuator 43. The two push rods 41 pass through the second vertical plate 104 and are slidably connected to the second vertical plate 104. One end of the two push rods 41 is connected to the two air outlet covers 36 respectively, and the other end of the two push rods 41 is connected to the connecting frame 42. The linear actuator 43 is installed inside the outer case 1, and the moving part of the linear actuator 43 is connected to the connecting frame 42. During the dust removal process, the linear actuator 43 operates and drives the connecting frame 42 to move back and forth. When the connecting frame 42 moves, it can drive the two push rods 41 to move, so that the two push rods 41 drive the two air outlet covers 36 to move back and forth. Under the action of the linear actuator 43, the air outlet covers 36 can move back and forth during the exhaust process. This mechanism effectively prevents excessive accumulation of dust at a certain position of the dust filter plate 2, and realizes uniform coverage of dust on the surface of the filter plate, which not only improves the dust removal efficiency, but also extends the service life of the dust filter plate 2, and avoids the problem of premature blockage or damage of the filter plate due to local accumulation of dust; Reference Figure 4, Figure 5 and Figure 8 The filter material regeneration unit includes two cleaning components and two collecting components. The two cleaning components are respectively arranged opposite to the two dust filter plates 2. The two collecting components are arranged on the first vertical plate 103. Each collecting component includes a dirt collecting box 58. The dirt collecting box 58 is arranged on the side of the first vertical plate 103. When the cleaning component is running, the dust on the surface of the dust filter plate 2 is scraped into the corresponding dirt collecting box 58. The cleaning component includes a horizontal plate 51, a shaft 52 and a cleaning plate 53. The horizontal plate 51 is located between the dust filter plate 2 and the air outlet cover 36. Brackets are fixed at both ends of the bottom surface of the horizontal plate 51. The shaft 52 is rotatably assembled between the two brackets. The cleaning plate 53 is fixed The horizontal plate 51 is sleeved on the shaft 52, one end of the shaft 52 is connected to the corresponding bracket through a torsion spring 54, a rod-shaped handle is fixed on the side of the horizontal plate 51, and one end of the rod-shaped handle away from the horizontal plate 51 passes through the second vertical plate 104 and is slidably connected to the second vertical plate 104, and a top rod 55 is also fixed on the side of the horizontal plate 51. The collection assembly also includes a sewage outlet 56 and a cover plate 57. The sewage outlet 56 is opened on the side of the first vertical plate 103, and the sewage outlet 56 is arranged opposite to the top rod 55. The cover plate 57 is rotatably assembled on the side of the first vertical plate 103, and the cover plate 57 is arranged opposite to the sewage outlet 56. The sewage collecting box 58 is located below the sewage outlet 56; The dust removal device proposed in the present invention also has the function of cleaning the dust filter plate 2, regenerating the dust filter plate 2 to restore the dust removal performance of the dust filter plate 2. Specifically, when it is necessary to clean the dust filter plate 2 during dust removal, the staff first controls the position of the guide plate 331 so that the guide plate 331 guides the gas to another air outlet end, so that the gas is discharged through another air outlet hood 36. Through this operation, the device can use another dust filter plate 2 to capture dust, and at the same time clean the previously used dust filter plate 2. When cleaning, the staff can push the rod-shaped handle to make the rod-shaped handle drive the horizontal plate 51 to move. In the initial state, under the action of the torsion spring 54, the cleaning plate 53 is in an inclined state. When the horizontal plate 51 moves, the cleaning plate 53 moves accordingly. When the cleaning plate 53 is connected with the dust filter plate 2, the cleaning plate 53 will rotate forward under the blocking effect of the dust filter plate 2 and apply torsion to the torsion spring 54. When the cleaning plate 53 moves to the top of the dust filter plate 2, the dust filter plate 2 can move toward the surface of the dust filter plate 2 under the elastic force of the torsion spring 54. The pressure is applied, and under the action of the pressure, the cleaning plate 53 can push the dust on the surface of the dust filter plate 2 during the movement, and push the dust to a position close to the sewage outlet 56. In this process, the elastic force provided by the torsion spring 54 can ensure the cleaning effect of the cleaning plate 53 on the dust. When the horizontal plate 51 moves to a position close to the sewage outlet 56, the top rod 55 on the horizontal plate 51 will first contact the cover plate 57 and push the cover plate 57 to rotate the cover plate 57. When the cover plate 57 rotates, the cover plate 57 no longer blocks the sewage outlet 56, which makes the cleaning plate The plate 53 can push the dust out through the sewage outlet 56. When the dust cleaning plate 53 is separated from the dust filter plate 2, the dust filter plate 2 no longer blocks the dust cleaning plate 53. At this time, the dust cleaning plate 53 will reverse and reset under the elastic force of the torsion spring 54. In this process, the swinging action of the dust cleaning plate 53 can push the dust out through the sewage outlet 56, so that the dust falls into the dust collecting box 58, thereby realizing automatic cleaning and collection of the dust. Through this cleaning mechanism, the dust removal performance of the dust filter plate 2 can be restored, and the staff does not need to frequently replace the dust filter plate 2, which provides convenience for the use of the dust removal device. It is worth noting that since the dust filter plate 2 is soaked by the water flow, the dust will be mixed in the water flow, and the wet dust filter plate 2 and the dust are more tightly combined, reducing the adhesion of the dust on the surface of the filter plate, which makes it easier to remove the dust from the surface of the filter plate when the cleaning plate 53 moves, avoiding the accumulation of dust on the filter plate, thereby improving the cleaning effect of the cleaning plate 53 on the dust. In addition, when the staff controls the horizontal plate 51 to reset, the cleaning plate 53 will contact the dust filter plate 2 again and rest on the dust filter plate 2. Under the obstruction of the dust filter plate 2, the cleaning plate 53 will rotate in the opposite direction. When the cleaning plate 53 rotates in the opposite direction, it will not apply force to the torsion spring 54, and the reaction force of the torsion spring 54 will not act on the cleaning plate 53. This makes the cleaning plate 53 not apply pressure to the dust filter plate 2 during the resetting process, avoiding unnecessary wear between the cleaning plate 53 and the dust filter plate 2, thereby improving the service life of the dust filter plate 2; Referring to Figures 4-6, water spray pipes 61 are fixed to the sides of the two air outlet hoods 36, and a plurality of water spray ports 62 are provided on the two water spray pipes 61, each of which is arranged downwardly, and a water circulation unit is arranged inside the outer case 1, the water circulation unit comprises a water storage tank 63, two water receiving tanks 64 and a water pump 65, the water storage tank 63 is arranged on the inner bottom surface of the outer case 1, the two water receiving tanks 64 are arranged on two partitions 105 respectively, the water pump 65 is installed on the side of the water storage tank 63, the water inlet end of the water pump 65 is connected to the water storage tank 63, the water outlet end of the water pump 65 is connected to a water supply pipe 66, and the end of the water supply pipe 66 away from the water pump 65 faces outward. The top of the chassis 1 is extended, and two connecting pipes 67 are connected to the water supply pipe 66. The ends of the two connecting pipes 67 away from the water supply pipe 66 are respectively connected to the two water spray pipes 61. The water storage tank 63 and the two water receiving tanks 64 are jointly provided with a return pipe structure, and the return pipe structure is used to guide the water flow in the two water receiving tanks 64 to the water storage tank 63. The return pipe structure includes a main return pipe and two branch return pipes. One end of the main return pipe is connected to the water storage tank 63, and the other end of the main return pipe extends toward the top of the outer chassis 1. One end of the two branch return pipes is connected to the main return pipe, and the other end of the two branch return pipes is respectively connected to the two water receiving tanks 64; In the process of capturing dust, the staff starts the water pump 65 simultaneously. When the water pump 65 is running, it can draw water from the water storage tank 63 and pump the water into the water supply pipe 66. Then, the water will enter the water spray pipe 61 through the connecting pipe 67 and finally be sprayed out through a plurality of water spray ports 62. When the air outlet hood 36 moves, the water spray pipe 61 moves accordingly. In this process, the water can be sprayed onto the dust filter plate 2 through a plurality of water spray ports 62, so that the water soaks the dust filter plate 2. This wet dust filter plate 2 significantly improves the capture of dust. The water flow not only helps to adhere to and fix the fine dust particles, but also reduces the rebound and escape of the dust on the surface of the filter plate, thereby improving the dust capture effect of the dust removal filter plate 2. The water overflowing from the dust removal filter plate 2 will drip into the water receiving box 64 and accumulate in the water receiving box 64. The water storage tank 63 is connected to the two water receiving boxes 64 through a return pipe structure. The water flow in the water receiving box 64 can flow into the main return pipe through the branch return pipe, and finally flow back to the water storage tank 63 through the main return pipe, thereby realizing the circulation of water.
