Description

Technical Field

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

[0002] Indoor construction projects belong to building decoration projects, including plastering, painting, tiling, curtain wall installation of interior and exterior walls, as well as interior ceiling, floor decoration, door and window installation, etc. When operating indoor projects, some operations will cause large-area dust flying, such as wall grinding, cutting of raw materials such as tiles and wood, etc. When performing such operations, personnel usually wear protective equipment such as masks. However, due to the small particle size of the fine dust in the air, it is easy to float in the air for a long time, which may cause damage to the human eyes and respiratory system. Most conventional air dust purification devices work on the suction (passive) principle. The air is drawn into the machine by an internal fan, and then various filters or technologies are used to filter and purify pollutants such as dust in the air. Due to the limited volume of general air dust purification devices, their suction range is limited, and it is difficult to suck dust at different heights. Moreover, when the human body is operating normally, since the human body will move within a certain range, and the suction range of general air dust purification devices is limited, it is difficult to accurately reduce the dust near the human head, which is rather inconvenient. Summary of the Invention

[0003] The purpose of the present invention is to provide an air dust purification device for construction engineering to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

A plurality of connecting pipes are fixedly connected to both ends of the rubber box. The rubber box is located below the rubber plate, and a rectangular groove is formed on the top surface of the rubber plate. A plurality of inflow holes are formed on the inner bottom surface of the rectangular groove. The two fixing plates are respectively fixedly connected to the bottom ends of the opposite sides of the rubber box. A plurality of jacks are formed on the top surface of any fixing plate. The two connecting plates are respectively located above the two fixing plates. The two connecting plates are both U-shaped, and a plurality of circular holes are formed on both arms of the two connecting plates. A plurality of screw holes are formed at both ends of any fixing plate. A plurality of sleeve holes are formed on the top surface of any connecting plate. The plurality of sleeve holes on any connecting plate correspond to the plurality of jacks on the adjacent fixing plate one by one. A positioning rod is fixedly sleeved inside any sleeve hole, and one end of any positioning rod is movably inserted into the adjacent jack. Both ends of any connecting rib are fixedly connected with a collar, and the inside of any collar is movably sleeved on the outer side wall of the adjacent positioning rod.

[0010] Furthermore, a support plate is provided above any connecting plate. A plurality of connecting holes are formed on the top surface of any support plate. The plurality of connecting holes on any support plate correspond to the plurality of positioning rods on the adjacent connecting plate one by one. The inner side wall of any connecting hole is fixedly sleeved on the outer side wall of the corresponding positioning rod.

[0011] Furthermore, two grating plates are provided above the rubber plate. Two connecting rings are fixedly connected to one side of any grating plate. The four connecting rings are respectively movably sleeved on the outer side walls of the four sleeves. An installation plate is detachably connected between the two grating plates.

[0012] Furthermore, a limiting ring is fixedly sleeved on the outer side wall of any sleeve, and any connecting ring is located above the adjacent limiting ring.

[0013] Furthermore, the separation mechanism includes:

[0014] A filter cloth for separating dust and water liquid in the muddy water and a winding rod for rotating and winding the filter cloth and squeezing the filter cloth. One end of the filter cloth is detachably connected to the top surface of the rubber plate. The filter cloth is located between the grating plate and the rubber plate, and the outer side wall of the winding rod is fixedly connected to the other end of the filter cloth.

[0015] Furthermore, both ends of the rubber box are fixedly connected with L-shaped plates. A chute is formed on one side of any one of the L-shaped plates. A motor box is arranged on one side of any one of the L-shaped plates. One end of any one of the motor boxes is fixedly connected with a slider. Any one of the sliders is slidably clamped inside the adjacent chute. A driving motor is arranged inside any one of the motor boxes. The motor shaft of any one of the driving motors is fixedly connected with the end of the adjacent winding rod. Two guide wheels are fixedly sleeved on the outer side wall of the winding rod.

[0016] Furthermore, a U-shaped frame is arranged above the two plate bodies. One ends of the two arms of the U-shaped frame are respectively rotatably connected with the top surfaces of the two plate bodies. The U-shaped frame is detachably connected with a plurality of fans.

[0017] Furthermore, two support plates are fixedly connected to the opposite sides of the two plate bodies respectively. A worm is rotatably connected between the two support plates on any one of the plate bodies. One ends of the two arms of the U-shaped frame are both fixedly connected with worm wheels. The two worm wheels are respectively meshed with the two worms.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By using the adsorption mechanism to release water mist from above the human body and cooperating with the collection mechanism to suck the water mist, the water mist moves along the path from above the human body to below the human body, so that the water mist first adsorbs the dust near the human head in the air, improves the protection effect on the human body, and makes the dust at different heights near the human body be adsorbed and settled by the water mist, further reducing the dust concentration. Moreover, in hot weather, part of the water mist can be evaporated by the high temperature, increasing the air humidity around and reducing the problem of dry air in the environment.

[0020] 2. By connecting the box body with the U-shaped plate, then using the water pump and the water pipe to inject water flow into the box body, and then starting the atomizer, the atomizer atomizes the water flow inside the box body into water mist and sprays it out. By rotating the two worms, the two worm wheels can be driven to rotate, so that the two worm wheels drive the U-shaped frame to rotate and adjust the angles of the multiple fans. Then start the fans to blow the water mist downward and adjust the moving direction of the water mist.

[0021] 3. By covering the rubber plate on the rubber box, and then connecting the air extraction pump with the connecting pipe through the conduit, the air extraction pump can suck the air above the grille plate to a certain extent through the inflow hole on the rubber plate, so as to guide the moving paths of the dust and the water mist.

[0022] 4. After the dust and water mist are mixed and fall onto the filter cloth, they will form a mud-like state. By starting two driving motors to drive the winding rod to rotate, while the winding rod rotates, it moves on the L-shaped plate relying on the guide wheel, and the winding rod drives the two motor boxes to move synchronously, so that the winding rod winds the filter cloth. When the motor box moves to the end of the chute, the guide wheel is located inside the arc-shaped groove to reduce the contact area with the L-shaped plate, so that the guide wheel can continue to rotate. Then the winding rod continues to rotate to tighten and squeeze the filter cloth, so that the mud-like dust and water flow are separated by squeezing the filter cloth. Then the winding rod is reset to make the filter cloth unfold again. If there is too much dust on the filter cloth and it affects the normal use of the air extraction pump, the filter cloth can be removed from the rubber plate and the dust can be manually cleaned, or the filter cloth can be directly replaced.

Detailed Embodiment

[0032] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0033] Please refer to Figures 1-8 , in the embodiments of the present invention, a building engineering air dust purification device includes:

[0034] A rubber plate 100, an adsorption mechanism 200 for generating water mist to adsorb tiny dust in the air, a collection mechanism 300 for collecting the water mist generated by the adsorption mechanism 200, and a separation mechanism 400 for separating dust from the water liquid. A plurality of connecting ribs 110 are provided inside the rubber plate 100. Both ends of any one of the connecting ribs 110 are located at opposite sides of the rubber plate 100 respectively. The adsorption mechanism 200 is located above the rubber plate 100. The adsorption mechanism 200 includes two plate bodies 210. And U-shaped plates 220 are provided on opposite sides of any one of the plate bodies 210. One end of each arm of any one of the U-shaped plates 220 is rotatably connected to the two plate bodies 210 respectively. A plurality of box bodies 230 are detachably connected between the two U-shaped plates 220. A water pipe is fixedly connected to one end of any one of the box bodies 230. An atomizer 231 is provided inside any one of the box bodies 230. The collection mechanism 300 is located below the rubber plate 100, and the separation mechanism 400 is located above the rubber plate 100.

[0035] Specifically, the atomizer 231 is an ultrasonic spray atomizer. When installing the box body 230, holes can be opened in the box body 230 and the U-shaped plate 220 and then connected by bolts and other connecting parts, so that the box body 230 can be disassembled and assembled from the U-shaped plate 220. The two U-shaped plates 220 can be rotated to a parallel state for connecting with the box body 230. During use, a plurality of box bodies 230 are located above the human body. Water is pumped through the water pipe into the inside of the box body 230. Then the liquid inside the box body 230 will be atomized into water mist by the atomizer 231. Since the water mist is heavier than air, it will naturally float down. Thus, the floating-down water mist naturally adsorbs and condenses with the dust in the air to form liquid droplets, and the liquid droplets will naturally fall and be collected by the collection mechanism 300 after that. Therefore, the water mist drifts down from above, passes through the human head first and then falls to the human feet. Thus, the dust near the human head is adsorbed first, giving priority to protecting the head and the respiratory system, and can cover the whole body of the human body, forming a continuous dust reduction path. This can ensure that dust is captured and settled by the water mist at different heights, reducing the suspension time of dust in the air and further reducing the dust concentration. Moreover, in hot weather, part of the water mist can be evaporated, thus increasing the air humidity around and reducing the problem of dry air in the environment.

[0036] Example 1

[0037] As Figures 1-2 shown, in this embodiment, two insertion cylinders are fixedly connected to one side of each of the two U-shaped plates 220. Four sleeves 120 are fixedly connected to the four corners of the top surface of the rubber plate 100, and the four sleeves 120 correspond to the four insertion cylinders one by one. An insertion rod 121 is provided between any one of the insertion cylinders and the corresponding sleeve 120. Both ends of any one of the insertion rods 121 are movably inserted into the adjacent sleeve 120 and the insertion cylinder respectively.

[0038] In this embodiment, when in use, the rubber plate 100 can be fixed to the collection mechanism 300. Then, after the two U-shaped plates 220 are rotated to a parallel state, the box body 230 is fixed to the two U-shaped plates 220, so that the box body 230 positions the two U-shaped plates 220, thereby making the relative positions of the two U-shaped plates 220 no longer change. Then, the four insertion rods 121 are inserted into the insertion cylinders and the sleeves 120, so that the insertion rods 121 provide support for the two U-shaped plates 220, making the two U-shaped plates 220 located above the human body. Moreover, the insertion rods 121 and the box body 230 are detachable, and the two U-shaped plates 220 can be folded in half, which is convenient for the user to carry and store.

[0039] As Figures 5-7 shown, in this embodiment, the collection mechanism 300 includes:

[0040] A rubber box 310 for collecting and receiving water flow, two fixed plates 320 supported on the ground, and two connecting plates 330 for supporting the rubber plate 100. A plurality of connecting pipes 311 are fixedly connected to both ends of the rubber box 310. The rubber box 310 is located below the rubber plate 100, and a rectangular groove is formed on the top surface of the rubber plate 100. A plurality of inflow holes 101 are formed on the bottom surface of the rectangular groove. The two fixed plates 320 are respectively fixedly connected to the bottom ends of the opposite sides of the rubber box 310. A plurality of jacks are formed on the top surface of any one of the fixed plates 320. The two connecting plates 330 are respectively located above the two fixed plates 320. The two connecting plates 330 are both U-shaped, and a plurality of circular holes are formed on both arms of the two connecting plates 330. A plurality of screw holes are formed at both ends of any one of the fixed plates 320. A plurality of sleeve holes are formed on the top surface of any one of the connecting plates 330. The plurality of sleeve holes on any one of the connecting plates 330 correspond to the plurality of jacks on the adjacent fixed plate 320 one by one. A positioning rod 331 is fixedly sleeved inside any one of the sleeve holes. One end of any one of the positioning rods 331 is movably inserted into the adjacent jack. Both ends of any one of the connecting ribs 110 are fixedly connected with a collar 111. The inside of any one of the collars 111 is movably sleeved on the outer wall of the adjacent positioning rod 331. A support plate 332 is arranged above any one of the connecting plates 330. A plurality of connection holes are formed on the top surface of any one of the support plates 332. The plurality of connection holes on any one of the support plates 332 correspond to the plurality of positioning rods 331 on the adjacent connecting plate 330 one by one. The inner wall of any one of the connection holes is fixedly sleeved on the outer wall of the corresponding positioning rod 331. Two grid plates 340 are arranged above the rubber plate 100. Two connection rings are fixedly connected to one side of any one of the grid plates 340. The four connection rings are respectively movably sleeved on the outer walls of the four sleeves 120. An installation plate 341 is detachably connected between the two grid plates 340. A limit ring is fixedly sleeved on the outer wall of any one of the sleeves 120. Any one of the connection rings is located above the adjacent limit ring.

[0041] In specific implementation, both the rubber box 310 and the rubber plate 100 are made of soft rubber material. By laying the two fixing plates 320 on the ground, and then screwing the two arms of the two connecting plates 330 through the circular holes and into the screw holes, the connecting plate 330 is fixed to the adjacent fixing plate 320, and the positioning rod 331 is inserted into the adjacent jack. Then, the rubber plate 100 is unfolded, and the collar 111 on the connecting rib 110 is sleeved on the adjacent positioning rod 331 until the collar 111 abuts against the adjacent supporting plate 332, so that the plurality of connecting ribs 110 support the rubber plate 100. The two grating plates 340 and the mounting plate 341 can be connected by connecting members such as bolts. By sleeving the connecting ring on the grating plate 340 on the sleeve 120 until the connecting ring is supported by the limiting ring, a U-shaped structure is formed between the plurality of connecting ribs 110, the plurality of positioning rods 331 and the two fixing plates 320 to support on the ground. A person can stand on the grating plate 340 and the mounting plate 341. After the water mist adsorbs dust and forms droplets, the droplets drip through the grating plate 340 into the rectangular groove on the rubber plate 100 and flow into the rubber box 310 through the inflow hole 101. The top surface of the rubber box 310 is closely attached to the bottom surface of the rubber plate 100. During use, an air pump can also be used to connect with the connecting pipe 311 through a conduit, so that the air above the rubber plate 100 can be sucked inside the rubber box 310 through the plurality of inflow holes 101, and the floating water mist and dust in the air are sucked. By the downward floating of the water mist and the suction of the water mist from below by the air pump, the dust removal path of the water mist from top to bottom is further limited. There is a certain space between the connecting pipe 311 and the inner bottom surface of the rubber box 310, and the bottom surface area of the rubber box 310 is large, so that the water flow inside the rubber box 310 is not easily sucked by the air pump. The air pump is a prior art and will not be elaborated here, so that the water flow can be collected for recycling.

[0042] As Figures 6-8 shown, in this embodiment, the separation mechanism 400 includes:

[0043] a filter cloth 410 for separating dust from the water in the muddy water and a winding rod 420 for rotating and winding the filter cloth 410 and squeezing the filter cloth 410. One end of the filter cloth 410 is detachably connected to the top surface of the rubber plate 100. The filter cloth 410 is located between the grating plate 340 and the rubber plate 100. The outer side wall of the winding rod 420 is fixedly connected to the other end of the filter cloth 410. Both ends of the rubber box 310 are fixedly connected with L-shaped plates 430. A sliding groove is opened on one side of any L-shaped plate 430. A motor box 440 is arranged on one side of any L-shaped plate 430. One end of any motor box 440 is fixedly connected with a slider, and any slider is slidably clamped inside the adjacent sliding groove. A driving motor is arranged inside any motor box 440, and the motor shaft of any driving motor is fixedly connected to the end of the adjacent winding rod 420. Two guide wheels 421 are fixedly sleeved on the outer side wall of the winding rod 420.

[0044] In specific implementation, a plurality of through holes are formed in one end of the filter cloth 410 and on the top surface of the rubber plate 100. Bolts can be passed through the through holes and then screwed with nuts to fix one end of the filter cloth 410 on the rubber plate 100. When the liquid drops onto the filter cloth 410, it can be naturally filtered by the filter cloth 410, so that the dust that gets wet and turns into mud falls on the filter cloth 410, and the water flows through the filter cloth 410 and falls into the rubber box 310. Then, by starting two driving motors to drive the winding rod 420 to rotate, the winding rod 420 rolls on two L-shaped plates 430 by relying on two guide wheels 421, so that the winding rod 420 can drive two motor boxes 440 to move along two chutes during rotation, and the winding rod 420 winds the filter cloth 410. Arc-shaped grooves are formed on the inner bottom surfaces of the two L-shaped plates 430. After the sliders on the two motor boxes 440 move to the ends of the chutes, the guide wheels 421 move into the arc-shaped grooves, reducing the contact surface with the L-shaped plates 430, causing the guide wheels 421 to slip. Then, the winding rod 420 continues to wind the filter cloth 410 to squeeze out the water contained in the mud-like dust, thereby improving the water collection effect. The rubber box 310 is relatively thick, and the two L-shaped plates 430 and the two fixing plates 320 are all made of hard materials. There is a gap between any L-shaped plate 430 and the adjacent fixing plate 320, so that the user can bend the rubber box 310 at the gap between the L-shaped plate 430 and the adjacent fixing plate 320, so that the rubber box 310 can be folded along its own diagonal. When passing through narrow doors and other places, the rubber box 310 can be folded to pass through the narrow door.

[0045] Embodiment 2

[0046] On the basis of Embodiment 1, a fan 241 is provided to facilitate controlling the floating direction of the water mist.

[0047] As Figures 2-3 shown, in this embodiment, a U-shaped frame 240 is arranged above the two plate bodies 210, and one ends of the two arms of the U-shaped frame 240 are respectively rotatably connected to the top surfaces of the two plate bodies 210. A plurality of fans 241 are detachably connected to the U-shaped frame 240. Two support plates are fixedly connected to the opposite sides of the two plate bodies 210. A worm 211 is rotatably connected between the two support plates on any one plate body 210. One ends of the two arms of the U-shaped frame 240 are fixedly connected with worm wheels 242, and the two worm wheels 242 are respectively meshed with the two worms 211.

[0048] In specific implementation, when in use, rotating the worm 211 drives the adjacent worm wheel 242 to rotate, causing the worm wheel 242 to drive the U-shaped frame 240 to rotate, thereby adjusting the angle of the fan 241. The fan 241 can be fixed to the U-shaped frame 240 through connectors such as screws. Then, the fan 241 is started to blow the water mist to adjust the direction of the water mist. And when the fan 241 blows the water mist, it can simultaneously blow the dust in the air, causing the dust to be blown downward by the fan 241. At the same time, the dust is sucked downward by the air extraction pump through the inflow hole 101 on the rubber plate 100, thereby restricting the movement path of the dust and reducing the dust near the human head. The suction force of the air extraction pump through the inflow hole 101 becomes weaker due to the blockage of the filter cloth 410. However, since the filter cloth 410 is relatively thin, although the suction force generated inside the rubber box 310 becomes weaker, the air extraction pump can still operate normally and generate a certain suction force on the dust above the grille plate 340. If muddy dust adheres to the filter cloth 410, after the muddy dust on the filter cloth 410 is squeezed dry by the winding rod 420, the filter cloth 410 can be removed from the rubber plate 100, and then the squeezed dust can be manually cleaned from the filter cloth 410, or the filter cloth 410 can be directly replaced.

[0049] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
