Description

Technical Field

[0001] This invention relates to the field of dust suppression equipment technology, specifically a covered indoor construction dust suppression device. Background Technology

[0002] Dust refers to solid particles suspended in the air, such as dust, abrasive particles, smoke, mineral dust, sand, and powder. These terms lack clear boundaries. The presence of dust in the atmosphere is one of the main reasons for maintaining the Earth's temperature; too much or too little dust in the atmosphere will have catastrophic effects on the environment. Indoor construction, such as decoration, demolition, plumbing and electrical work, and wall sanding, generates dust that not only pollutes the environment but also harms the health of construction workers and those around them, while also increasing the difficulty of subsequent cleaning. Dust and debris are unavoidable during indoor construction. Dust control measures at construction sites are crucial. The impact of dust on construction sites not only affects the health of construction workers but also impacts construction efficiency and quality; handling every detail is critical.

[0003] Currently, existing methods for dust suppression during indoor construction can only handle large dust particles, and are ineffective at dealing with small, suspended dust particles. This results in dust filling the air, which not only pollutes the atmosphere and is detrimental to environmental protection, but also causes workers to inhale large amounts of dust, affecting their health. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: A covered indoor construction dust suppression device, comprising: The machine body, and the fan fixedly installed on the top side of the machine body, the top of the fan is equipped with an air inlet hopper, the bottom of the machine body is equipped with a sewage pipe, and the top of the inner cavity of the machine body is equipped with a pre-treatment device. The air inlet hopper is funnel-shaped to increase the air intake range, cover the indoor construction site, and further promote dust reduction at the construction site. The dust suppression mechanism includes a triangular plate and a pump body. One end of the triangular plate is fixedly installed on the side of the inner wall of the machine body, and the pump body is fixedly installed on the bottom of the machine body surface. A cylinder is fixedly connected to the end of the triangular plate away from the inner wall of the machine body. The outlet of the pump body is connected to a bent pipe, which penetrates the machine body and extends into it. A filter screen is fixedly installed at the inlet of the pump body. A guide rod is fixedly connected to the bottom of the outer surface of the cylinder. A spray assembly is installed between the outlet of the bent pipe and the top of the inner cavity of the cylinder. The dust carried by the airflow enters the inside of the cylinder, and under the guidance of the cylinder, the airflow moves downward and extends through the bottom of the cylinder to the water body at the bottom of the inner cavity of the machine body, so that the dust carried by the airflow comes into full contact with the water body, thereby adsorbing and treating the residual small dust particles. The spray assembly includes a rotating connector and a bracket. The rotating connector is installed at the outlet of the bent pipe. Both ends of the bracket are fixedly connected to the top of the inner cavity of the cylinder. A connecting pipe is rotatably installed between the top of the rotating connector and the center of the bracket. A conical block is fixedly connected to the top of the connecting pipe, and blades are fixedly connected to the surface of the conical block. A dust filter is fixedly connected to the outer surface of the connecting pipe. A spray head is connected to the outlet of the outer surface of the connecting pipe. Airflow blows onto the surface of the blades, causing the blades to be subjected to the blowing force of the airflow. Combined with the bracket, the connecting pipe is rotated and supported, causing the connecting pipe to drive the dust filter to rotate. The rotating connector installed at the bottom of the connecting pipe ensures that the dust filter rotates smoothly and is not prone to jamming. Thus, the spiral dust filter rotates, keeping the dust filter dynamic at all times, without dead corners, promoting the treatment of suspended dust.

[0005] Preferably, the cylinder is installed vertically, and the top of the cylinder is conical, with the cylinder installed directly above the liquid outlet of the bent pipe.

[0006] Preferably, the inlet end of the pump body penetrates through the surface of the machine body and extends into its interior, the guide rod is installed vertically, there are two guide rods, and the two guide rods are installed symmetrically along the central axis at the middle of the cylinder.

[0007] Preferably, the connecting pipe is installed vertically, with its axis coinciding with the central axis of the cylinder. The inlet at the bottom of the connecting pipe is connected to the outlet of the bent pipe. The blades are installed at an angle and are evenly distributed on the surface of the conical block. The pump's suction draws out some water from the bottom of the machine's internal cavity. As the water passes through the filter screen, it filters out dust and residue. Under the transport of the bent pipe, the water enters the interior of the connecting pipe and is sprayed from the spray head into the interior of the cylinder, thus spraying dust into the cylinder.

[0008] Preferably, the dust filter is spiral-shaped and is evenly distributed in the middle of the outer circular surface of the connecting pipe. The spray head is installed between the dust filter and the bracket and is evenly distributed at the liquid outlet on the outer circular surface of the connecting pipe.

[0009] Preferably, the pretreatment process includes a dust collector and an air duct. The dust collector is fixedly installed on the side of the machine body surface. The top of the air duct is fixedly installed to the side of the top of the machine body cavity by screws. The air inlet of the air duct is connected to the air outlet at the bottom of the fan. The air outlet of the air duct is connected to the top of the cylinder. A first dust collection pipe is connected to the side of the bottom of the air duct. A second dust collection pipe is connected to the middle of the bottom of the air duct. The end of the second dust collection pipe away from the bottom of the air duct is connected to the middle of the surface of the first dust collection pipe. The first and second dust collection pipes are connected at the top of their inner cavities, and conical rings are fixedly connected to the top of their inner cavities. By using a fan to draw in air from the construction site, dust particles will enter the interior of the duct along with the airflow. Since the duct is S-shaped, the direction of airflow can be changed, and the speed of airflow will also change, causing large dust particles to fall due to their own gravity. The first and second dust collection pipes collect and guide the falling large dust particles, allowing them to smoothly enter the interior of the dust collector.

[0010] Preferably, the air duct is S-shaped, and the first dust collection pipe and the second dust collection pipe are installed directly below the air duct.

[0011] When large dust particles enter the first and second dust collection pipes, they pass through the center of the conical ring. The conical ring gradually decreases in diameter from top to bottom, which prevents the large dust particles from flowing back and promotes dust collection.

[0012] Preferably, the bottom end of the first dust collection pipe penetrates the inner wall of the machine body and extends into the interior of the dust collector, and the inner diameter of the conical ring gradually decreases from top to bottom.

[0013] Preferably, an auxiliary mechanism is installed on the surface of the cylinder. The auxiliary mechanism includes a connecting ring. The inner side of the connecting ring is slidably installed between the inner side of the connecting ring and the surface of the cylinder via a guide rod. A conical floating ring is fixedly connected to the bottom of the connecting ring. A square hole is opened at the top of the surface of the conical floating ring. A Y-shaped tooth is fixedly connected to the side of the surface of the connecting ring. A striking block is fixedly connected to the top of the Y-shaped tooth. When the conical floating ring floats on the surface of the water, a large number of bubbles are generated when the airflow passes through the cylinder and enters the water at the bottom of the machine's internal cavity. With the support of the connecting ring, the conical floating ring always floats on the outer surface of the cylinder, which can intercept the bubbles and make them less likely to float. This increases the contact time between the gas and the water at the bottom of the machine's internal cavity, thereby helping to absorb residual suspended dust.

[0014] As bubbles gather on the inner side of the conical float ring and at the bottom of the connecting ring, and with the continuous airflow entering the water from inside the cylinder, the number of bubbles increases, applying an upward pushing force to the conical float ring and the connecting ring. Combined with the striking block installed directly below the air duct, and connected by Y-shaped teeth, the connecting ring drives the Y-shaped teeth and the striking block to move upward together. This causes the striking block to strike the bottom of the second dust collection pipe. Since both the first and second dust collection pipes are made of elastic material, the second dust collection pipe vibrates, causing the first dust collection pipe to vibrate as well. This promotes the falling of large particles of debris inside both dust collection pipes, reducing the likelihood of blockage.

[0015] Preferably, the cylinder passes through the center of the connecting ring and the center of the conical float ring. The inner diameter of the connecting ring gradually increases from top to bottom. The square holes are evenly distributed on the top of the surface of the conical float ring. As bubbles gather on the inner side of the conical float ring, some bubbles will pass through the square holes and burst, creating a scene of boiling water bubbles rolling upwards and bursting. By bursting the bubbles, the upward force of the bubbles on the conical float ring and the connecting ring is reduced. The connecting ring can then drive the striking block to move downwards for resetting, which helps to strike again later. This process of repeated striking is repeated.

[0016] This invention provides a covered indoor construction dust suppression device. It has the following beneficial effects: (i) This covered indoor construction dust suppression device utilizes the dust carried by the airflow to enter the interior of the cylinder. Under the guidance of the cylinder, the airflow moves downward and extends through the bottom of the cylinder to the water body at the bottom of the machine's internal cavity, so that the dust carried by the airflow can fully contact the water body and adsorb the residual small dust particles.

[0017] (ii) This covered indoor construction dust suppression device uses a funnel-shaped air intake hopper to increase the air intake range, cover the indoor construction site, and further promote dust suppression at the construction site.

[0018] Third, this covered indoor construction dust suppression device uses airflow to blow on the surface of the blades, so that the blades are subjected to the blowing force of the airflow, which causes the connecting pipe to drive the dust filter to rotate. This makes the dust filter rotate smoothly and is not prone to jamming. By using the spiral dust filter to rotate, the dust filter always keeps dynamic and there are no dead corners, which promotes the treatment of suspended dust.

[0019] IV. This covered indoor construction dust suppression device uses the suction of the pump body to draw out some water from the bottom of the inner cavity of the machine. When the water passes through the filter screen, it will filter out dust and residue. Under the transportation of the bend pipe, the water enters the interior of the connecting pipe and is sprayed out from the spray head into the interior of the cylinder to perform spray dust suppression on the dust that enters the cylinder.

[0020] 5. This covered indoor construction dust suppression device uses a fan to draw in air from the indoor construction site. Dust particles enter the interior of the air duct along with the airflow. The S-shaped curve of the air duct changes the direction of airflow and the speed of airflow, causing large dust particles to fall due to their own gravity. The first and second dust collection pipes collect and guide the falling large dust particles, allowing them to smoothly enter the interior of the dust collector.

[0021] VI. In this covered indoor construction dust suppression device, large dust particles enter the interior of the first and second dust collection pipes. The large dust particles pass through the center of the conical ring, and the inner diameter of the conical ring gradually decreases from top to bottom, which can prevent the large dust particles from flowing back, thereby promoting the collection of dust.

[0022] 7. When the airflow passes through the cylinder and enters the water at the bottom of the machine's internal cavity, a large number of bubbles are generated. With the support of the connecting ring, the conical floating ring always floats on the outer surface of the cylinder, which can intercept the bubbles and make them less likely to float. This increases the contact time between the gas and the water at the bottom of the machine's internal cavity, thereby helping to absorb residual suspended dust.

[0023] 8. This covered indoor construction dust suppression device uses air bubbles to apply upward pushing force to the conical floating ring and connecting ring, causing the connecting ring to drive the Y-shaped teeth and the striking block to move upward together. This allows the striking block to strike the bottom of the second dust collection pipe, causing the second dust collection pipe to vibrate and causing the first dust collection pipe to vibrate as well. This promotes the falling of large particles of debris inside the first and second dust collection pipes, making it less likely to cause blockage.

[0024] 9. In this indoor construction dust suppression device, as bubbles gather on the inner side of the conical floating ring, some bubbles will pass through the square holes and burst, creating a scene similar to boiling water bubbles rolling upwards and breaking. By bursting the bubbles, the upward force of the bubbles on the conical floating ring and the connecting ring is reduced, and the connecting ring can drive the striking block to move downwards to reset it, which helps to strike again later. This process is repeated in a cycle. Attached Figure Description

[0027] 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.

[0028] For the first embodiment, please refer to... Figure 1-4 The present invention provides a technical solution: A covered indoor construction dust suppression device, comprising: The machine body 1 and the fan 2 fixedly installed on the top side of the machine body 1. The top of the fan 2 is equipped with an air inlet 3, the bottom of the machine body 1 is equipped with a sewage pipe 4, and the top of the inner cavity of the machine body 1 is equipped with a pretreatment device 5. The air inlet 3 is funnel-shaped to increase the air intake range, cover the indoor construction site, and further promote dust reduction at the construction site. The dust suppression mechanism 6 includes a triangular plate 61 and a pump body 62. One end of the triangular plate 61 is fixedly installed on the side of the inner wall of the machine body 1. The pump body 62 is fixedly installed on the bottom of the surface of the machine body 1. A cylinder 63 is fixedly connected to the end of the triangular plate 61 away from the inner wall of the machine body 1. The outlet of the pump body 62 is connected to a bent pipe 64. The bent pipe 64 passes through the machine body 1 and extends into its interior. A filter screen 65 is fixedly installed at the inlet of the pump body 62. A guide rod 66 is fixedly connected to the bottom of the outer surface of the cylinder 63. A spray assembly 67 is installed between the outlet of the bent pipe 64 and the top of the inner cavity of the cylinder 63. The dust carried by the airflow enters the interior of the cylinder 63. Under the guidance of the cylinder 63, the airflow moves downward and extends through the bottom end of the cylinder 63 to the water body at the bottom of the inner cavity of the machine body 1, so that the dust carried by the airflow comes into full contact with the water body and adsorbs the residual small dust particles. The cylinder 63 is installed vertically, and the top of the cylinder 63 is conical. The cylinder 63 is installed directly above the liquid outlet of the bent pipe 64.

[0029] The inlet end of the pump body 62 penetrates the surface of the machine body 1 and extends into its interior. The guide rod 66 is installed vertically. There are two guide rods 66, and the two guide rods 66 are installed symmetrically along the central axis at the middle of the cylinder 63.

[0030] The spray assembly 67 includes a rotary connector 671 and a bracket 672. The rotary connector 671 is installed at the outlet of the bent pipe 64. Both ends of the bracket 672 are fixedly connected to the top of the inner cavity of the cylinder 63. A connecting pipe 677 is rotatably installed between the top of the rotary connector 671 and the center of the bracket 672. A conical block 673 is fixedly connected to the top of the connecting pipe 677. A blade 674 is fixedly connected to the surface of the conical block 673. A dust filter 675 is fixedly connected to the outer circular surface of the connecting pipe 677. The outlet of the outer circular surface of the connecting pipe 677 is connected to... With a spray head 676, when the airflow blows into the inside of the cylinder 63, the airflow blows onto the surface of the blades 674, causing the blades 674 to be subjected to the blowing force of the airflow. Combined with the bracket 672, the connecting pipe 677 is rotated and supported, causing the connecting pipe 677 to drive the dust filter 675 to rotate. The bottom of the connecting pipe 677 is equipped with a rotating connector 671, which allows the dust filter 675 to rotate smoothly and is not prone to jamming. Thus, by using the spiral dust filter 675 to rotate, the dust filter 675 always remains dynamic and there are no dead corners.

[0031] The connecting pipe 677 is installed vertically, and the axis of the connecting pipe 677 coincides with the central axis of the cylinder 63. The liquid inlet at the bottom of the connecting pipe 677 is connected to the liquid outlet of the bent pipe 64. The blades 674 are installed at an angle and are evenly distributed on the surface of the conical block 673.

[0032] The operator starts the pump body 62 and uses the suction of the pump body 62 to draw out some water from the bottom of the inner cavity of the machine body 1. When the water passes through the filter screen 65, it will filter out the dust and residue. Under the transportation of the bent pipe 64, the water enters the interior of the connecting pipe 677 and is sprayed out from the spray head 676 into the interior of the cylinder 63 to spray and suppress the dust that has entered the interior of the cylinder 63.

[0033] The dust filter 675 is spiral-shaped and is evenly distributed in the middle of the outer circle of the connecting pipe 677. The spray head 676 is installed between the dust filter 675 and the bracket 672 and is evenly distributed at the liquid outlet on the outer circle of the connecting pipe 677.

[0034] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 6 As shown: The pretreatment process 5 includes a dust collector 51 and an air duct 52. The dust collector 51 is fixedly installed on the side of the surface of the body 1. The top of the air duct 52 is fixedly installed on the side of the top of the inner cavity of the body 1 by screws. The air inlet of the air duct 52 is connected to the air outlet at the bottom of the fan 2. The air outlet of the air duct 52 is connected to the top of the cylinder 63. A first dust collection pipe 53 is connected to the side of the bottom of the air duct 52. A second dust collection pipe 54 is connected to the middle of the bottom of the air duct 52. The end of the second dust collection pipe 54 away from the bottom of the air duct 52 is connected to the middle of the surface of the first dust collection pipe 53. Conical rings 55 are fixedly connected to the top of the inner cavity of the first dust collection pipe 53 and the top of the inner cavity of the second dust collection pipe 54. By using the fan 2 to draw in the air at the construction site, dust will enter the interior of the air duct 52 along with the airflow. Since the air duct 52 is S-shaped, the direction of airflow can be changed, and the speed of airflow will also change, so that large dust particles will fall due to their own gravity. The first dust collection pipe 53 and the second dust collection pipe 54 collect and guide the falling large dust particles, so that the large dust particles can smoothly enter the interior of the dust collector 51.

[0035] The air duct 52 is S-shaped. The first dust collection pipe 53 and the second dust collection pipe 54 are installed directly below the air duct 52. When large dust particles enter the interior of the first dust collection pipe 53 and the second dust collection pipe 54, the large dust particles will pass through the center of the conical ring 55. The inner diameter of the conical ring 55 gradually decreases from top to bottom to prevent the large dust particles from flowing back.

[0036] The bottom end of the first dust collection pipe 53 penetrates the inner wall of the body 1 and extends into the interior of the dust collector 51, and the inner diameter of the conical ring 55 gradually decreases from top to bottom.

[0037] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 8 As shown: An auxiliary mechanism 7 is installed on the surface of the cylinder 63. The auxiliary mechanism 7 includes a connecting ring 71. The inner side of the connecting ring 71 is slidably installed between the cylinder 63 and the surface of the cylinder 63 via a guide rod 66. A conical float ring 72 is fixedly connected to the bottom of the connecting ring 71. A square hole 73 is opened at the top of the surface of the conical float ring 72. A Y-shaped tooth 74 is fixedly connected to the side of the surface of the connecting ring 71. A striking block 75 is fixedly connected to the top of the Y-shaped tooth 74. The conical float ring 72 floats on the surface of the water. When the airflow passes through the cylinder 63 and enters the water at the bottom of the inner cavity of the machine body 1, a large number of bubbles will be generated. With the support of the connecting ring 71, the conical float ring 72 always floats on the outer surface of the cylinder 63, which can intercept the bubbles and make them less likely to float. This increases the contact time between the gas and the water at the bottom of the inner cavity of the machine body 1, thereby helping to absorb residual suspended dust.

[0038] As bubbles gather on the inner side of the conical float ring 72 and at the bottom of the connecting ring 71, and with the continuous airflow entering the water from inside the cylinder 63, the number of bubbles increases, applying an upward pushing force to the conical float ring 72 and the connecting ring 71. Combined with the striking block 75 installed directly below the air duct 52 and connected by the Y-shaped teeth 74, the connecting ring 71 drives the Y-shaped teeth 74 and the striking block 75 to move upward together. This allows the striking block 75 to strike the bottom of the second dust collection pipe 54. Since both the first and second dust collection pipes 53 and 54 are made of elastic material, the second dust collection pipe 54 vibrates, causing the first dust collection pipe 53 to vibrate as well. This promotes the falling of large particles of debris inside the first and second dust collection pipes 53 and 54, preventing blockages.

[0039] The cylinder 63 passes through the center of the connecting ring 71 and the center of the conical float ring 72. The inner diameter of the connecting ring 71 gradually increases from top to bottom. The square holes 73 are evenly distributed on the top of the surface of the conical float ring 72. As bubbles gather on the inner side of the conical float ring 72, some bubbles will pass through the square holes 73 and burst, forming a scene of boiling water bubbles rolling upward and bursting. By bursting the bubbles, the upward force of the bubbles on the conical float ring 72 and the connecting ring 71 is reduced. Then, the connecting ring 71 can drive the striking block 75 to move downward for reset, which helps to strike again later. This process of repeated striking is repeated.

[0040] When in use, first move the indoor construction dust suppression device to the designated location on the construction site, and inject an appropriate amount of water into the body 1 so that the conical floating ring 72 contacts the water surface and the conical floating ring 72 is buoyed by the water. At this time, the staff turns on the fan 2 to work. The air intake hopper 3 is funnel-shaped to increase the air intake range and cover the indoor construction site. The fan 2 draws in the air at the indoor construction site, and the dust will enter the interior of the air duct 52 along with the airflow. The air duct 52 is S-shaped, which can change the direction of airflow and change the speed of airflow. This causes large dust particles to fall due to their own gravity. The first dust collection pipe 53 and the second dust collection pipe 54 collect and guide the falling large dust particles, so that the large dust particles can smoothly enter the interior of the dust collector 51. When large dust particles enter the interior of the first dust collection pipe 53 and the second dust collection pipe 54, the large dust particles will pass through the center of the conical ring 55, and the inner diameter of the conical ring 55 gradually decreases from top to bottom to prevent the large dust particles from flowing back. Furthermore, when the airflow blows into the interior of the cylinder 63, it blows onto the surface of the blades 674, causing the blades 674 to be subjected to the blowing force of the airflow. Combined with the bracket 672, the connecting pipe 677 is rotated and supported, causing the connecting pipe 677 to drive the dust filter 675 to rotate. The bottom of the connecting pipe 677 is equipped with a rotating connector 671, which allows the dust filter 675 to rotate smoothly and is not prone to jamming. Thus, by using the spiral dust filter 675 to rotate, the dust filter 675 always remains dynamic and there are no dead corners. At the same time, the staff started the pump body 62 to work, using the suction of the pump body 62 to suck out some water from the bottom of the inner cavity of the machine body 1. When the water passes through the filter screen 65, it will filter out the dust and residue. Under the transportation of the bent pipe 64, the water enters the interior of the connecting pipe 677 and is sprayed from the spray head 676 into the interior of the cylinder 63 to spray and suppress the dust that has entered the interior of the cylinder 63. Furthermore, the dust carried by the airflow enters the interior of the cylinder 63, and under the guidance of the cylinder 63, the airflow moves downward and extends through the bottom end of the cylinder 63 to the water body at the bottom of the inner cavity of the machine body 1, so that the dust carried by the airflow comes into full contact with the water body and adsorbs the residual small dust particles. Furthermore, by using the conical floating ring 72 to float on the surface of the water, when the airflow passes through the cylinder 63 and enters the water at the bottom of the inner cavity of the machine body 1, a large number of bubbles will be generated. With the support of the connecting ring 71, the conical floating ring 72 will always float on the outer surface of the cylinder 63, which can intercept the bubbles and make them less likely to float up. This increases the contact time between the gas and the water at the bottom of the inner cavity of the machine body 1, thereby helping to absorb residual suspended dust. As bubbles gather on the inner side of the conical float ring 72 and at the bottom of the connecting ring 71, and with the continuous airflow entering the water from inside the cylinder 63, the number of bubbles increases, applying an upward pushing force to the conical float ring 72 and the connecting ring 71. Combined with the striking block 75 installed directly below the air duct 52 and connected by the Y-shaped teeth 74, the connecting ring 71 drives the Y-shaped teeth 74 and the striking block 75 to move upward together. This allows the striking block 75 to strike the bottom of the second dust collection pipe 54. Since both the first and second dust collection pipes 53 and 54 are made of elastic material, the second dust collection pipe 54 vibrates, causing the first dust collection pipe 53 to vibrate as well. This promotes the falling of large particles of debris inside the first and second dust collection pipes 53 and 54, reducing the likelihood of blockage. As bubbles gather on the inner side of the conical float ring 72, some bubbles will pass through the square hole 73 and burst, creating a scene of boiling water bubbles rolling upwards and breaking. By bursting the bubbles, the upward force of the bubbles on the conical float ring 72 and the connecting ring 71 is reduced, and the connecting ring 71 can drive the striking block 75 to move downwards to reset, which helps to strike again later. This process of striking is repeated in a cycle.
