Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a liftable dust collection device for building construction. Background Technology

[0002] Construction dust mainly originates from earthwork excavation, concrete mixing, wall construction, and decoration, and is characterized by its dispersed generation points, wide pollution range, and long duration. Especially in high-rise building construction, as the working height increases, dust is easily dispersed to surrounding areas by airflow, not only affecting the health of construction workers but also seriously impacting the living environment of nearby residents, transportation, and the overall ecological environment.

[0003] Long-term exposure to high dust levels can easily lead to respiratory diseases in construction workers, such as pneumoconiosis, bronchitis, and asthma. Related medical research indicates that pneumoconiosis in the construction industry is showing a trend towards affecting younger people. Furthermore, heavy metal particles in the dust (such as lead and mercury) can enter the bloodstream through the respiratory tract, damaging the nervous, digestive, and immune systems, posing a long-term potential threat to human health. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a liftable dust collection device for construction engineering, comprising: a base frame, a rotating frame fixedly installed inside the base frame, two rotating frames being provided, a lifting frame being rotatably installed on the surface of the two rotating frames, an installation plate being fixedly installed on the top of the lifting frame, and a hydraulic push rod being fixedly installed on the side of the top of the base frame, the hydraulic push rod being fixedly installed on the side of the bottom of the installation plate; A collection component for dust storage is fixedly mounted at the center of the top of the mounting plate; A conveying assembly is used to separate easily entangled impurities during dust extraction and conveying during construction. A dust suction duct is fixedly installed on the outer surface of the conveying assembly, and the conveying assembly is installed on top of the collecting assembly. A mixing and dispersing component is used to disperse collected clumps of dust. This component is rotatably installed inside the collection component. Construction projects generate a large amount of dust. During dust collection, the suction duct is made of a molded material. Workers adjust the angle of the suction duct to change its position relative to the building, and then activate the lifting frame to adjust its angle. This causes the mounting plate to move the collection component up and down, allowing workers to collect dust from higher areas during dust collection. The collected dust flows through the suction duct into the conveying component and accumulates within the collection component. The mixing and dispersing component inside the collection component disperses the collected dust clumps.

[0005] Preferably, the collection assembly includes a collection cylinder, with locking blocks fixedly installed on both sides of the top of the collection cylinder, and four stabilizing seats fixedly installed at the bottom of the collection cylinder. The four stabilizing seats are symmetrically arranged around the collection cylinder, and a water injection pipe is fixedly installed on the outer surface of the collection cylinder. After dust is collected, it is stored in the collection cylinder. For subsequent dust recycling, workers inject water into the collection cylinder through the water injection pipe. A rotating blade mixes the water and dust to form a slurry that can be directly used in subsequent construction. Because some dust is sticky, the arc-shaped blade, with its gentle stirring and soft peeling properties, prevents the sticky dust from adhering firmly, effectively handling the sticky slurry.

[0006] Preferably, the stabilizing base is fixedly installed on the top of the mounting plate, the locking block is engaged with the conveying component, and the collecting cylinder is connected to the conveying component through the locking block.

[0007] Preferably, the conveying assembly includes a dust cover, a vacuum cleaner is fixedly installed at the center of the top of the dust cover, a handle and a connecting pipe are fixedly installed on the outer surface of the vacuum cleaner, a hook-shaped component is fixedly installed inside the connecting pipe, and buckles are fixedly installed on both sides of the top of the dust cover. When the worker starts the vacuum cleaner, the vacuum cleaner generates suction to suck up the dust from the construction site through the suction duct. The sucked-up dust is collected in the collection cylinder. During the dust suction process, fibrous and easily entangled impurities at the construction site are also affected by the suction and sucked into the collection assembly along the suction duct. Easily entangled impurities entering the collection cylinder can easily become entangled with the mixing and dispersing components, causing the mixing and dispersing components to become unbalanced and their speed to decrease, which in turn causes abnormal noise and vibration in the equipment. To prevent easily entangled impurities from entering the collection cylinder, a hook-shaped component is installed inside the connecting pipe to hook the easily entangled impurities, thereby separating the easily entangled impurities from the dust. The dust cover and the collection cylinder are fixed together by buckles and locking blocks. The worker can remove the dust cover to clean the easily entangled impurities hooked on the hook-shaped component.

[0008] Preferably, the buckle and the locking block are engaged and adapted, the hook-shaped part extends through the connecting tube into the interior of the vacuum cleaner, and the connecting tube is fixedly connected to the vacuum suction tube.

[0009] Preferably, the hook-shaped component includes a mounting ring, on the outer surface of which a connecting strip is fixedly mounted. Several connecting strips are arranged circumferentially on the surface of the mounting ring. A serrated blade and a pressure pad are fixedly mounted on the surface of each connecting strip, the pressure pad being made of a flexible material. The mounting ring is mounted on the surface of the connecting tube, and the connecting strip extends through the mounting ring into the interior of the connecting tube. The serrated blades on the connecting strips have sharp, serrated sides. When easily entangled impurities are drawn into the connecting tube by suction, the serrated blades hook the impurities, preventing them from entering the collection cylinder. Furthermore, the serrated blades and pressure pads are evenly distributed inside the connecting tube. When dust particles flow with the airflow, the serrated blades and pressure pads prevent particles from continuously accumulating in the same position, avoiding the formation of a hard accumulation layer. If this accumulation layer is not cleaned in time, it can reduce the effective inner diameter of the pipe, leading to a decrease in airflow velocity and further exacerbating blockage. In scenarios with a sudden increase in dust generation, high-concentration dust clumps can easily form inside the pipe. If these clumps directly impact the inner wall of the pipe, they can easily adhere and form blockages. The serrated blades and the extrusion pads can break up dust clumps into small particle groups, reduce the adsorption force between particles, and guide the particles to be evenly distributed with the airflow, reducing the accumulation caused by excessively high local concentrations. Preferably, the mixing and dispersing component includes a motor, a protective cover fixedly mounted on the outer surface of the motor, a rotating shaft fixedly mounted on the output end of the motor, a dispersing component rotatably mounted on the outer surface of the rotating shaft, a side connecting block fixedly mounted on the top of the rotating shaft, and a curved block fixedly mounted on the surface of the side connecting block. When the operator starts the motor, the dispersing component agitates the dust accumulated in the collection cylinder as the output end of the motor drives the rotating shaft to rotate. The side connecting block and the curved block are located below the exhaust port of the vacuum cleaner. When the dust falls, the side connecting block and the curved block will separate the falling positions, thereby preventing the dust from accumulating in one place and causing the dust to accumulate too thickly, affecting subsequent collection.

[0010] Preferably, the motor is fixedly installed at the bottom of the collecting cylinder, and the agitator is rotatably installed inside the collecting cylinder, with the agitator rubbing against the inner wall of the collecting cylinder.

[0011] Preferably, the agitator includes a positioning triangular plate, a retaining pad fixedly installed inside the positioning triangular plate, a spring fixedly installed on the top of the retaining pad, a round block fixedly installed on the top of the spring, and a lever fixedly installed on the bottom of the round block. Two levers are provided, and a spring band is fixedly installed between the adjacent surfaces of the two levers. When the positioning triangular plate rotates with the shaft, the levers installed inside the retaining pad agitate the dust in the collection cylinder. Because the retaining pad is made of flexible material, it is flung outwards by centrifugal force during rotation, causing the spring band installed between the two levers to be stretched and deformed. When the flexible retaining pad rotates inside the collection cylinder, the flexible medium only breaks up clumps when in contact with the dust, without compacting the dust, ensuring that the dust remains loose and facilitating subsequent unloading without damaging intact dust particles. Some construction dust needs to be reused or mixed with other materials in a fixed proportion. If, after dust collection, coarse particles sink and fine particles float due to differences in particle size and density, the proportions will be unbalanced during subsequent mixing. The stirring action of the paddle ensures that dust particles of different sizes and densities are thoroughly mixed, guaranteeing that the dust concentration and composition of each extracted portion are consistent, thus providing a guarantee for the quality control of reuse or the stable effect of disposal.

[0012] Preferably, the positioning triangle is fixedly installed on the outer surface of the rotating shaft, the paddle is made of a flexible material, and the paddle is frictionally adapted to the inner wall of the collecting cylinder.

[0013] This invention provides a liftable dust collection device for construction engineering. It has the following beneficial effects: I. This construction project's liftable dust collection equipment addresses the large amount of dust generated during construction. The dust collection duct, made of a molded material, allows workers to adjust its angle to change its position relative to the building. The lifting frame is then activated, causing the mounting plate to move the collection assembly up and down. This facilitates the collection of dust from higher areas during site cleaning. The collected dust flows through the dust collection duct into the conveying assembly and accumulates there. The mixing and dispersing components within the collection assembly further disperse the clumps of dust.

[0014] II. The construction project's liftable dust collection equipment collects dust into a collection cylinder. For subsequent dust recycling, workers inject water into the collection cylinder through a water injection pipe. A rotating blade mixes the water and dust to create a slurry that can be directly used in subsequent construction. Since some dust is sticky, the arc-shaped blades gently stir the sticky slurry, and through their soft peeling properties, the sticky dust does not adhere firmly, effectively handling the sticky slurry.

[0015] III. The construction project's liftable dust collection equipment works by having workers start a vacuum cleaner, which generates suction to draw dust from the construction site through a suction duct. The collected dust is then deposited into a collection cylinder. During the dust collection process, fibrous and easily entangled impurities from the construction site are also drawn in by the suction and enter the collection assembly through the suction duct. These easily entangled impurities can easily become entangled with the mixing and dispersing components, causing imbalance and a decrease in rotation speed, which in turn can lead to abnormal noise and vibration in the equipment. To prevent these easily entangled impurities from entering the collection cylinder, hook-shaped parts are installed inside the connecting pipe to catch them, thus separating them from the dust. The dust cover is fixed to the collection cylinder with clips and blocks. Workers can remove the dust cover to clean the easily entangled impurities caught on the hook-shaped parts.

[0016] IV. The construction project's liftable dust collection equipment is installed on the surface of the connecting pipe via an mounting ring. The connecting strip extends into the connecting pipe through the mounting ring. The serrated edges of the connecting strip are sharp and serrated. When easily entangled impurities are drawn into the connecting pipe by suction, the serrated edges hook these impurities, preventing them from entering the collection cylinder. Furthermore, the serrated edges and pressure pads are evenly distributed inside the connecting pipe. As dust particles flow with the airflow, the serrated edges and pressure pads prevent particles from continuously accumulating in the same location, avoiding the formation of a hard accumulation layer. If this accumulation layer is not cleaned in time, it can reduce the effective inner diameter of the pipe, causing a decrease in airflow velocity and further exacerbating blockage. In scenarios with a sudden increase in dust generation, high-concentration dust clumps can easily form inside the pipe. If these clumps directly impact the inner wall of the pipe, they can easily adhere and cause blockages. The serrated edges and pressure pads can break up dust clumps into smaller particle groups, reducing the adsorption force between particles and guiding the particles to distribute evenly with the airflow, reducing the accumulation caused by excessively high local concentrations. V. This construction project's liftable dust collection equipment, through the rotation of a positioning triangular plate along a rotating shaft, agitates the dust within the collection cylinder using paddles installed inside the clamping pad. Because the clamping pad is made of flexible material, it is flung outwards by centrifugal force during rotation, causing the elastic band installed between the two paddles to deform under tension. When the flexible clamping pad rotates within the collection cylinder, the flexible medium, upon contact with the dust, only breaks up clumps, preventing dust compaction and ensuring the dust remains loose. This facilitates subsequent unloading without damaging intact dust particles. Some construction dust requires reuse or needs to be mixed with other materials in a fixed ratio. If, after collection, the dust exhibits stratification due to differences in particle size and density, with coarse particles settling and fine particles floating, it can lead to an imbalance in the mixing ratio during subsequent mixing. The paddle agitation ensures thorough mixing of dust with different particle sizes and densities, guaranteeing consistent dust concentration and composition in each collected portion, thus providing a guarantee for stable quality control and disposal during reuse.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] First embodiment, such as Figures 1 to 10As shown, the present invention provides a technical solution: a liftable dust collection device for construction engineering, comprising: a base frame 7, a rotating frame 5 fixedly installed inside the base frame 7, two rotating frames 5 are provided, a lifting frame 8 is rotatably installed on the surface of the two rotating frames 5, an installation plate 4 is fixedly installed on the top of the lifting frame 8, a hydraulic push rod 6 is fixedly installed on the side of the top of the base frame 7, and the hydraulic push rod 6 is fixedly installed on the side of the bottom of the installation plate 4; Collection component 3, which is used for dust storage, is fixedly installed at the middle of the top of the mounting plate 4; Conveying component 2 is used to separate easily entangled impurities during dust suction and conveying during construction. A dust suction duct 1 is fixedly installed on the outer surface of the conveying component 2, and the conveying component 2 is installed on top of the collecting component 3. A mixing and dispersing component 9 is used to disperse collected clumps of dust. This component 9 is rotatably installed inside the collecting component 3. Construction projects generate a large amount of dust. When collecting this dust, the suction duct 1, made of a molded material, is adjusted by workers to change its position relative to the building. Then, the angle of the lifting frame 8 is adjusted, causing the mounting plate 4 to move the collecting component 3 up and down. This allows workers to collect dust from higher areas during dust collection at the construction site. The collected dust flows along the suction duct 1 into the conveying component 2 and accumulates in the collecting component 3. The mixing and dispersing component 9 within the collecting component 3 disperses the collected dust clumps.

[0021] The collection component 3 includes a collection cylinder 31. Two locking blocks 34 are fixedly installed on the top two sides of the collection cylinder 31. Four stabilizing supports 32 are fixedly installed at the bottom of the collection cylinder 31, symmetrically arranged around the collection cylinder 31. A water injection pipe 33 is fixedly installed on the outer surface of the collection cylinder 31. After dust collection, the dust is collected in the collection cylinder 31. For subsequent dust recycling, workers inject water into the collection cylinder 31 through the water injection pipe 33. A rotating paddle 933 mixes the water and dust to form a slurry that can be directly used in subsequent construction. Because some dust is sticky, the arc-shaped paddle 933, with its flexible stirring and soft peeling properties, prevents sticky dust from adhering firmly, effectively handling the sticky slurry.

[0022] The stabilizing base 32 is fixedly installed on the top of the mounting plate 4, the locking block 34 is engaged and adapted with the conveying component 2, and the collecting cylinder 31 is connected to the conveying component 2 through the locking block 34.

[0023] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 7 As shown, the mixing and dispersing component 9 includes a motor 91, a protective cover 92 fixedly installed on the outer surface of the motor 91, a rotating shaft 94 fixedly installed at the output end of the motor 91, a dispersing component 93 rotatably installed on the outer surface of the rotating shaft 94, a side connecting block 96 fixedly installed on the top of the rotating shaft 94, and a curved block 95 fixedly installed on the surface of the side connecting block 96. When the operator starts the motor 91, the dispersing component 93 agitates the dust accumulated in the collection cylinder 31 when the output end of the motor 91 drives the rotating shaft 94 to rotate. The side connecting block 96 and the curved block 95 are located below the exhaust port of the vacuum cleaner 21. When the dust falls, the side connecting block 96 and the curved block 95 will separate the falling position, thereby preventing the dust from accumulating in one place and causing the dust to accumulate too thickly, affecting subsequent collection.

[0024] The motor 91 is fixedly installed at the bottom of the collecting cylinder 31, and the agitator 93 is rotatably installed inside the collecting cylinder 31. The agitator 93 is frictionally adapted to the inner wall of the collecting cylinder 31.

[0025] The stirring component 93 includes a positioning triangle plate 932, a retaining pad 934 is fixedly installed inside the positioning triangle plate 932, a spring 935 is fixedly installed on the top of the retaining pad 934, a round block 931 is fixedly installed on the top of the spring 935, and a paddle 933 is fixedly installed on the bottom of the round block 931. There are two paddles 933, and a spring band 936 is fixedly installed between the adjacent surfaces of the two paddles 933. As the positioning triangle 932 rotates with the shaft 94, the paddles 933 installed inside the pad 934 agitate the dust in the collection cylinder 31. Because the pad 934 is made of flexible material, it is flung outwards by centrifugal force during rotation, causing the elastic band 936 installed between the two paddles 933 to deform under tension. When the flexible pad 934 rotates inside the collection cylinder 31, the flexible medium only breaks up clumps of dust, preventing compaction and ensuring the dust remains loose. This facilitates subsequent unloading without damaging intact dust particles. Some construction dust needs to be reused or mixed with other materials in a fixed ratio. If, after collection, the dust exhibits stratification due to differences in particle size and density (coarse particles sinking, fine particles floating), it can lead to an imbalance in the mixing ratio during subsequent mixing. The agitation by the paddles 933 ensures thorough mixing of dust with different particle sizes and densities, guaranteeing consistent dust concentration and composition in each collected portion. This provides assurance for quality control during reuse or stable disposal.

[0026] The positioning triangle plate 932 is fixedly installed on the outer surface of the rotating shaft 94, and the paddle 933 is made of flexible material. The paddle 933 is frictionally adapted to the inner wall of the collecting cylinder 31.

[0027] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 10As shown, the conveying assembly 2 includes a dust cover 26, a vacuum cleaner 21 is fixedly installed at the middle of the top of the dust cover 26, a handle 24 and a connecting tube 22 are fixedly installed on the outer surface of the vacuum cleaner 21, a hook-shaped part 25 is fixedly installed inside the connecting tube 22, and buckles 23 are fixedly installed on both sides of the top of the dust cover 26. Workers start the vacuum cleaner 21, which generates suction to extract dust from the construction site through the suction duct 1. The extracted dust is collected in the collection cylinder 31. During the dust extraction process, fibrous and easily entangled impurities at the construction site are also affected by the suction and are sucked into the collection component 3 along the suction duct 1. Easily entangled impurities entering the collection cylinder 31 can easily become entangled with the mixing and dispersing component 9, causing the mixing and dispersing component 9 to become unbalanced and its speed to decrease, which in turn causes abnormal noise and vibration of the equipment. To prevent easily entangled impurities from entering the collection cylinder 31, a hook-shaped part 25 is installed inside the connecting pipe 22 to hook the easily entangled impurities, thereby separating the easily entangled impurities from the dust. The dust cover 26 is fixed to the collection cylinder 31 by a buckle 23 and a locking block 34. Workers can remove the dust cover 26 to clean the easily entangled impurities hooked on the hook-shaped part 25.

[0028] The buckle 23 and the locking block 34 are engaged and adapted to each other. The hook-shaped part 25 extends through the connecting tube 22 into the interior of the vacuum cleaner 21. The connecting tube 22 is fixedly connected to the vacuum suction tube 1.

[0029] The hook-shaped component 25 includes a mounting ring 251. A connecting strip 252 is fixedly mounted on the outer surface of the mounting ring 251. Several connecting strips 252 are provided and distributed in a circumferential shape on the surface of the mounting ring 251. A serrated blade 254 and a compression pad 253 are fixedly mounted on the surface of the connecting strip 252 respectively. The compression pad 253 is made of a flexible material. The mounting ring 251 is installed on the surface of the connecting pipe 22. The connecting strip 252 extends into the interior of the connecting pipe 22 through the mounting ring 251. The serrated blades 254 on the connecting strip 252 have sharp, serrated sides. When easily entangled impurities are drawn into the connecting pipe 22 by suction, the serrated blades 254 hook the impurities to prevent them from entering the collection cylinder 31. In addition, the serrated blades 254 and the compression pads 253 are evenly distributed inside the connecting pipe 22. When dust particles flow with the airflow, the serrated blades 254 and the compression pads 253 can prevent particles from continuously accumulating in the same position, avoiding the formation of a hard accumulation layer. If the accumulation layer is not cleaned in time, it will reduce the effective inner diameter of the pipe, causing the airflow speed to decrease and further aggravating the blockage. In scenarios where the amount of dust generated increases sharply, high-concentration dust clumps are easily formed inside the pipe. If they directly impact the inner wall of the pipe, they are prone to sticking together and forming a blockage. The serrated blade 254 and the extrusion pad 253 can break up dust clumps into small particle groups, reduce the adsorption force between particles, and guide the particles to be evenly distributed with the airflow, reducing the accumulation caused by excessive local concentration.

[0030] During use, a large amount of dust is generated during construction. When collecting and treating the dust, the suction duct 1 is made of a plastic material. The staff adjusts the tilt angle of the suction duct 1 to change the position between the suction duct 1 and the building. Then, the angle of the lifting frame 8 is adjusted, so that the mounting plate 4 drives the collection component 3 to rise and fall, so that the staff can collect the dust at high places when vacuuming the construction site. The collected dust enters the conveying component 2 along the suction duct 1 and gathers in the collection component 3. The mixing and dispersing component 9 in the collection component 3 disperses the collected dust and disperses the absorbed dust clumps.

[0031] Workers start the vacuum cleaner 21, which generates suction to extract dust from the construction site through the suction duct 1. The extracted dust is collected in the collection cylinder 31. During the dust extraction process, fibrous and easily entangled impurities at the construction site are also affected by the suction and are sucked into the collection component 3 along the suction duct 1. Easily entangled impurities entering the collection cylinder 31 can easily become entangled with the mixing and dispersing component 9, causing the mixing and dispersing component 9 to become unbalanced and its speed to decrease, which in turn causes abnormal noise and vibration of the equipment. To prevent easily entangled impurities from entering the collection cylinder 31, a hook-shaped part 25 is installed inside the connecting pipe 22 to hook the easily entangled impurities, thereby separating the easily entangled impurities from the dust. The dust cover 26 is fixed to the collection cylinder 31 by a buckle 23 and a locking block 34. Workers can remove the dust cover 26 to clean the easily entangled impurities hooked on the hook-shaped part 25.

[0032] The mounting ring 251 is installed on the surface of the connecting pipe 22. The connecting strip 252 extends into the interior of the connecting pipe 22 through the mounting ring 251. The serrated blades 254 on the connecting strip 252 have sharp, serrated sides. When easily entangled impurities are drawn into the connecting pipe 22 by suction, the serrated blades 254 hook the impurities to prevent them from entering the collection cylinder 31. In addition, the serrated blades 254 and the compression pads 253 are evenly distributed inside the connecting pipe 22. When dust particles flow with the airflow, the serrated blades 254 and the compression pads 253 can prevent particles from continuously accumulating in the same position, avoiding the formation of a hard accumulation layer. If the accumulation layer is not cleaned in time, it will reduce the effective inner diameter of the pipe, causing the airflow speed to decrease and further aggravating the blockage. In scenarios where the amount of dust generated increases sharply, high-concentration dust clumps are easily formed inside the pipe. If they directly impact the inner wall of the pipe, they are prone to sticking together and forming a blockage. The serrated blades 254 and the squeezing pads 253 can break up dust clumps into small particle groups, reducing the adsorption force between particles, and guiding the particles to be evenly distributed with the airflow, reducing the accumulation caused by excessively high local concentrations. When the operator starts the motor 91, the output end of the motor 91 drives the rotating shaft 94 to rotate, and the agitator 93 agitates the dust accumulated in the collection cylinder 31. The side block 96 and the curved block 95 are located below the exhaust port of the vacuum cleaner 21. When the dust falls, the side block 96 and the curved block 95 will separate the falling position, thereby preventing the dust from accumulating in one place, causing the dust to accumulate too thickly and affecting subsequent collection.

[0033] As the positioning triangle 932 rotates with the shaft 94, the paddles 933 installed inside the pad 934 agitate the dust in the collection cylinder 31. Because the pad 934 is made of flexible material, it is flung outwards by centrifugal force during rotation, causing the elastic band 936 installed between the two paddles 933 to deform under tension. When the flexible pad 934 rotates inside the collection cylinder 31, the flexible medium only breaks up clumps of dust, preventing compaction and ensuring the dust remains loose. This facilitates subsequent unloading without damaging intact dust particles. Some construction dust needs to be reused or mixed with other materials in a fixed ratio. If, after collection, the dust exhibits stratification due to differences in particle size and density (coarse particles sinking, fine particles floating), it can lead to an imbalance in the mixing ratio during subsequent mixing. The agitation by the paddles 933 ensures thorough mixing of dust with different particle sizes and densities, guaranteeing consistent dust concentration and composition in each collected portion. This provides assurance for quality control during reuse or stable disposal.

[0034] After dust is collected, it is stored in the collection cylinder 31. In subsequent dust recycling, the staff injects water into the collection cylinder 31 through the water injection pipe 33. The water and dust are mixed by the rotating blade 933 to form a slurry that can be directly used in subsequent construction. Since some dust is sticky, the arc-shaped blade 933 can gently stir the sticky slurry and peel it off easily, making it difficult for sticky dust to adhere firmly. This can effectively handle sticky slurry.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
