[0001] The invention relates to dust removal equipment for building construction, in particular to dust removal equipment for green building construction applied in the field of construction dust removal equipment. Background Art

[0002] During the construction process, the control of dust and pollutants is crucial. In order to avoid the interference of construction ground dust on the construction environment and to ensure the health of construction workers, suction filtration and spraying water mist are usually used to perform corresponding dust removal operations. However, in actual operations, the two methods are often used in combination, resulting in water vapor in the dust during suction, which sticks to the surface of the filter belt and is difficult to clean by scraping and vibration.

[0003] The specification of Chinese invention patent CN118045435B discloses a dust collector for construction projects, which solves the problem that dust at construction sites is relatively moist and easily adheres to filter equipment and is difficult to detach, causing the filter equipment to be clogged with dust and difficult to use, increasing the difficulty and frequency of cleaning.

[0004] When dealing with the problem of the filter belt being difficult to clean due to the suction of dust containing water vapor, existing construction dust removal equipment uses the method of drying first and then cleaning, which makes the dust removal process more cumbersome and the dust on the surface of the filter belt is not properly handled. In addition, if the filter belt is washed with water, the water will be polluted after multiple washings, which will cause the cleaning quality of the filter belt surface to decrease, and then result in the need to change the water after each cleaning, resulting in increased water resource consumption.

[0007] In the above-mentioned dust removal equipment for green building construction, dust blockages containing water vapor are effectively cleaned, and the filter belt is cleaned by water washing in an energy-saving manner on the basis of controlling water resource consumption.

[0008] As a further improvement of the present application, the cross-sectional dimension of the filter belt is larger than the cross-sectional dimension of the suction port, and the surface of the filter belt is in close contact with the surface of the suction port.

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1-5 A dust removal device for green building construction is shown, comprising a dust removal box 1, a rectangular suction port 101 is provided on one side surface of the dust removal box 1, a suction fan 2 is installed on the inner wall of the dust removal box 1 away from the suction port 101, a filter belt 4 is installed inside the dust removal box 1 through three rotating shafts, and the cross section of the filter belt 4 is a right triangle, a dust reduction water frame 6 is installed inside the dust removal box 1, and water mixed with flocculants is contained inside the dust reduction water frame 6, and depressions are provided at the four corners of the inner wall of the dust reduction water frame 6, and the upper rotating rod 9 and the lower rotating rod 12 arranged up and down are rotatably connected inside the depression, and the surface of the lower rotating rod 12 is wound with an isolation belt 8, and the isolation belt 8 is divided into a hollow area 801 and an isolation area 802, and the filter diameter of the isolation area 802 is smaller than the filter diameter of the filter belt 4; The upper rotating rod 9 and the lower rotating rod 12 are connected by a conveyor belt 11, and the conveyor belt 11 is located in the depression. In the initial state, the upper rotating rod 9 is located above the dust-reducing water frame 6. Both ends of the upper rotating rod 9 are rotatably connected with extension blocks. A servo motor 7 is installed on the surface of one of the extension blocks, and the output end of the servo motor 7 is connected to the end of one of the upper rotating rods 9. Two electric extension rods 5 symmetrically arranged about the dust-reducing water frame 6 are installed inside the dust removal box 1, and the power end of the electric extension rod 5 is fixedly connected to the bottom of the extension block; The cross-sectional dimensions of the filter belt 4 in the vertical direction, the cross-sectional dimensions of the inner wall of the dust-reducing water frame 6 and the cross-sectional dimensions of the isolation belt 8 are all the same.

[0021] The cross-sectional dimension of the filter belt 4 is larger than the cross-sectional dimension of the suction port 101 , and the surface of the filter belt 4 is in close contact with the surface of the suction port 101 .

[0022] The three rotating shafts are arranged with one up and two down. A driving motor 3 is installed on the surface of the dust removal box 1, and the output end of the driving motor 3 is connected to the end of the rotating shaft located at the top, and the two rotating shafts located at the bottom are penetrated and rotatably connected to the inside of the dust removal water frame 6.

[0023] The inner wall of the dust reduction water frame 6 is rotatably installed with a rotating rod 602 located between two horizontally arranged rotating shafts, the surface of the rotating rod 602 is installed with an eccentrically arranged knocking rod, the surface of the dust reduction water frame 6 is installed with a rotating motor, and the output end of the rotating motor is connected to one of the ends of the rotating rod 602.

[0024] Specifically, the length of the isolation zone 802 is greater than the cross-sectional length of the dust reduction water frame 6. Therefore, when the isolation zone 802 is in the upper state, the cross-sectional size design of the isolation belt 8 can effectively isolate and intercept the cross-sectional area of ​​the dust reduction water frame 6.

[0025] When using the present application for suction dust removal, the suction fan 2 is started to drive the external air of the dust removal box 1 into the interior of the dust removal box 1. During this process, the dust in the air is intercepted by the surface of the filter belt 4 attached to the surface of the suction port 101.

[0026] With the long-term suction interception treatment, the surface of the filter belt 4 in the area corresponding to the suction port 101 is in a blocked state, and the corresponding area of ​​the filter belt 4 (hereinafter referred to as the contaminated area) needs to be cleaned accordingly. At this time, the servo motor 7 is used to drive the conveyor belt 11 to rotate, and the isolation belt 8 is indirectly adjusted so that the hollow area 801 faces upward and the isolation area 802 faces downward (such as Figure 6 As shown), and the isolation belt 8 is placed in a lower position in the dust reduction water frame 6 (at this time, there is a certain vertical gap between the contaminated area of ​​the filter belt 4 and the hollow area 801, which is convenient for subsequent knocking and cleaning), and the drive motor 3 is started to drive the filter belt 4 to adjust its position, so that the contaminated area is gradually transferred to the inside of the dust reduction water frame 6, and then the drive motor 3 is stopped, so that the uncontaminated filter belt 4 can be sucked and intercepted, and the contaminated area of ​​the filter belt 4 is displaced to the inside of the dust reduction water frame 6. At this time, the rotating motor is started to drive the knocking rod to knock the contaminated area of ​​the filter belt 4 immersed in the dust reduction water frame 6, so that the dust blockage containing water vapor on the surface of the filter belt 4 can be effectively cleaned.

[0027] After the knocking cleaning is completed, the electric extension rod 5 moves up, and the servo motor 7 is used to indirectly drive the isolation belt 8 to rotate, so that the isolation area 802 faces upward, until the surface of the isolation area 802 is in contact with the surface of the filter belt 4, and then the electric extension rod 5 drives the isolation belt 8 to move downward. As the isolation area 802 faces upward, during the downward movement, the dirt in the water body of the dust reduction water frame 6 after immersion cleaning can be intercepted and concentratedly isolated below the isolation area 802 (such as Figure 7-8 As shown), then let it stand for a while, waiting for the area of ​​the filter belt 4 to be contaminated again after adjustment, and flocculation and sedimentation are carried out to make the upper liquid in the dust reduction water frame 6 return to a relatively clear state (because of the size difference between the isolation area 802 and the filter diameter of the filter belt 4, the isolation area 802 can effectively intercept the dirt cleaned up after interception on the surface of the filter belt 4), waiting for the next round of cleaning. In the next round of cleaning, the hollow area 801 needs to be adjusted to an upward state first.

[0028] When it is necessary to adjust the cleaned contaminated area to the oblique edge area of ​​the filter belt 4 (that is, the area close to the suction fan 2), the drive motor 3 is restarted, and the surface of the cleaned filter belt 4 will contact the surface of the wiping rod 10, and any objects that may remain on the surface of the filter belt 4 will be scraped off, thereby further enhancing the cleanliness of the surface of the filter belt 4 after cleaning.

[0029] Figure 5 It is shown that a liquid level sensor is installed inside the dust reduction water frame 6, a sewage pipe 601 with its tail end extending to the outside of the dust removal box 1 is installed through the inner wall of the dust reduction water frame 6 near the bottom wall, and an electromagnetic valve is installed on the surface of the sewage pipe 601, and wiping rods 10 located on both sides of the filter belt 4 are installed on the inner wall of the dust reduction water frame 6, and the wiping rods 10 are located above the horizontally arranged rotating shaft.

[0030] Specifically, with the increase in the number of flocculation and sedimentation times, the liquid level height in the dust reduction water frame 6 increases and exceeds the set safety threshold (the liquid level rises due to the accumulation of the flocculation sedimentation layer, and the safety threshold is set according to the actual situation). At this time, the liquid level sensor can control the solenoid valve to open, and the water in the dust reduction water frame 6 and the sedimentation layer are discharged through the sewage pipe 601, and wait for subsequent water replenishment (a water inlet pipe is installed inside the dust reduction water frame 6, which is not drawn in the figure, and the end of the water inlet pipe extends to the outside of the dust removal box 1. Since the water inlet pipe is a prior art, no further elaboration is made).

[0031] It also includes a dust removal control system, which includes an adjustment module, a lifting and isolation module and a shaking cleaning module, wherein the adjustment module is connected to the drive motor 3 signal for adjusting the contact area between the filter belt 4 and the suction port 101, the lifting and isolation module is connected to the electric extension rod 5 and the servo motor 7 signal for adjusting the distribution state of the hollow area 801 and the isolation area 802, and the shaking cleaning module is connected to the rotating motor and the lifting and isolation module signal for cleaning blockages on the surface of the filter belt 4.

[0032] Specifically, during shaking cleaning, the lifting isolation module needs to make the isolation area 802 face downward, and the isolation belt 8 is in a lower state, so as to provide space for shaking cleaning. The lifting isolation module is used to cooperate with the servo motor 7 to adjust the surface area of ​​the isolation belt 8, and cooperate with the electric extension rod 5 to adjust the spatial height of the isolation belt 8.

[0033] The second implementation method: Figure 9-10 It is shown that an extension groove is provided on the inner wall of one side of the hollow area 801, and multiple elastic tubes 803 are installed inside the extension groove, and the cross-section of the elastic tube 803 is Z-shaped. Control valve No. 1 and control valve No. 2 are respectively installed at both ends of the elastic tube 803. The length of the elastic tube 803 after stretching is not less than the height value of the dust suppression water frame 6.

[0034] In the initial state, both ends of the elastic tube 803 are flush with the top and bottom of the isolation belt 8, respectively, and the folded portion of the elastic tube 803 is arranged horizontally.

[0035] It also includes a dust removal and cleaning module, which is connected to the liquid level sensor, control valve No. 1 and control valve No. 2 by signal, and is used to discharge the sewage in the dust removal water frame 6 through the sewage pipe 601 after stirring the flocculation sedimentation layer on the bottom wall of the dust removal water frame 6.

[0036] Different from the first embodiment, this embodiment is mainly aimed at the flocculation sedimentation layer in the first embodiment accumulated on the bottom wall of the dust reduction water frame 6, which is in a relatively sticky state (similar to the state of silt), resulting in the sewage pipe 601 being inconvenient in discharging the flocculation sedimentation layer and water body in the dust reduction water frame 6.

[0037] Specifically, when sewage needs to be discharged, the isolation belt 8 is lifted to an upper position by the electric extension rod 5 (that is, the entire isolation belt 8 is immersed in the upper clear liquid after standing), and the isolation area 802 is facing upward, and then the No. 1 control valve is opened to allow the clear liquid to enter the elastic tube 803, and the length of the elastic tube 803 is increased, and the bottom end of the elastic tube 803 falls and contacts the bottom wall of the dust suppression water frame 6, and then the servo motor 7 is used to drive the isolation belt 8 to rotate, thereby driving the hollow area 801 to move in the horizontal direction, and driving the elastic tube 803 after water injection to move, so as to stir the flocculation sedimentation layer (such as Fig.11 As shown), the state of sedimentation accumulation is destroyed. During this process, the isolation area 802 is always in an upward state, and the flocculation sedimentation layer can be stirred and mixed, so that the state of the water body on the bottom wall of the dust reduction water frame 6 changes from the initial adhesion state to a turbid state, and then it can be discharged relatively smoothly through the sewage pipe 601. Finally, open the No. 2 control valve to discharge the water body in the elastic tube 803, so that the elastic tube 803 returns to its original state.

[0038] In summary, the present application utilizes the cooperation of the dust reduction water frame 6, the isolation belt 8 and the electric extension rod 5, so that when the filter belt 4 knocks to clean the blockage containing water vapor on the surface, the water body after immersion cleaning can be intercepted and isolated, so that the blockage in the cleaned sewage is isolated in the lower area and will not interfere with the subsequent immersion cleaning. The presence of the wiping rod 10 can further enhance the cleaning effect on the surface of the filter belt 4. In addition, in conjunction with the elastic tube 803, when discharging sewage, the design of the water-injected elastic tube 803 can be utilized to destroy the adhesion state of the flocculation sedimentation layer on the bottom wall of the dust reduction water frame 6, which is convenient for subsequent sewage treatment. After the sewage is discharged, the No. 2 control valve is opened to discharge the water injected in the elastic tube 803, thereby playing a supplementary cleaning role.

[0039] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
