Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a road dust absorption device for building civil engineering. Background Art

[0002] In each link of construction, such as excavation and drilling, mixing operations, plastering and grinding, a large amount of dust will be generated, which will not only pollute the environment of the construction site, but also harm the health of construction workers. When using water spray to reduce dust on the construction site, wet dust is not only difficult to clean, but the wastewater is also easy to pollute the surrounding environment. At the same time, due to the low friction of wet dust, it is easy to cause construction workers to slip when walking, and it will also cause vehicles to slip, affecting driving safety. At the same time, during the driving process of the vehicle, wet dust adheres to the vehicle, making it difficult to clean the vehicle. Wet dust will also cause corrosion to the metal parts of the vehicle.

[0003] The dust absorption devices commonly used in current construction projects include bag dust collectors, mobile vacuum cleaners, cartridge dust collectors, etc. The principle of most of them is to absorb dust into the filter material part, so that the filter material can capture the dust particles in the air, thereby realizing the separation of dust and air. However, in construction projects, in order to prevent dust from drifting, spray systems such as fog cannons are used in construction sites to reduce dust. This results in the above-mentioned dust collectors and vacuum cleaners. During the actual working process, as the dust contacts the filter material, the moisture combined with the dust will moisten the filter material, and as the filter material filters the dust, under the action of moisture, the air passing efficiency of the filter material decreases, thereby affecting the actual filtering effect, and will also affect the service life of the filter material. Summary of the invention

[0006] The inside of the shell is fixedly connected with a fan and a dust suction pipe, the air inlet end of the dust suction pipe is connected with the air outlet of the fan, the middle part of the dust suction pipe is a contraction section and is connected with a converging pipe, the air outlet end of the dust suction pipe is fixedly connected with a filter mechanism, the outer side surface of the dust suction pipe close to the air outlet end is fixedly connected with a plurality of semiconductor chips, the outer sides of the plurality of semiconductor chips are fixedly sleeved with a heat conducting ring, the heat conducting ring is fixedly sleeved with a heat conducting pipe, and the heat conducting pipe is fixedly connected with a heat dissipation plate;

[0007] The filtering mechanism comprises a filtering shell, the heat sink is embedded in the filtering shell, a stepping motor is fixedly connected to the inside of the shell, the output shaft of the stepping motor passes through the filtering shell and is fixedly sleeved with a filter.

[0008] Preferably, the filter includes a grid frame and a plurality of filter nets, the grid frame is located inside the filter shell and is concentric with the filter shell, a plurality of snap-in grooves are provided on the grid frame, filter nets are movably snap-inned in the snap-in grooves, the diameter of the filter nets is the same as the diameter of the air outlet end of the dust suction pipe, and the filter nets are made of hydrophobic fibers.

[0009] Preferably, the bottom of the filter shell is fixedly connected with a communicating dust exhaust port, the two opposite inner sides of the filter shell are fixedly connected with a knocking rod, the two sides of the grid are fixedly connected with a dial wheel, and the side of the dial wheel facing the knocking rod is fixedly connected with a protrusion.

[0010] Preferably, there are gaps between the knocking rod and the filter housing and the grid, and the knocking rod is made of elastic material. After the protrusion on the dial squeezes the knocking rod and separates from it, the knocking rod vibrates back and forth and knocks the filter housing and the grid.

[0011] Preferably, an exhaust pipe and a water vapor pipe are fixedly connected to one side of the filter shell away from the dust suction pipe, and the other ends of the exhaust pipe and the water vapor pipe both penetrate the shell and communicate with the outside.

[0012] Preferably, a ash bag bin is fixedly opened in the shell, the dust discharge port passes through the top surface of the ash bag bin and extends into the ash bag bin, a dust collecting bag sleeved on the dust discharge port is arranged in the ash bag bin, and a ash bag door is hinged at the ash bag bin.

[0013] Preferably, an inspection door is hinged on the rear side of the shell, and a plurality of casters are fixedly connected to the bottom surface of the base.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. In the present invention, through the dust suction pipe, after the fan is started, as the outside air is pumped into the air inlet end of the dust suction pipe by the fan, the moist dust around the base floats up under the suction of the fan, and at the same time, the dust inlet connected to the contraction end of the dust suction pipe generates suction, thereby sucking in the moist dust suspended nearby, and then driven by the airflow, the moist dust moves to the air outlet end of the dust suction pipe. At this time, after the moist dust enters the area where the semiconductor chip is located, the moisture wrapped in the dust crystallizes due to cooling. After the ice crystals continue to contact the filter along the airflow, the filter captures the ice crystals. At this time, the dust is wrapped by ice crystals and stays on the filter. As the stepper motor works, the filter moves to the next position. When the filter moves to the position corresponding to the heat sink, the heat generated by the semiconductor chip heats the ice crystals on the filter through the heat sink to melt them. At this time, the water generated by the melting drives the remaining ice crystals and dust to flow, thereby separating from the filter and finally being discharged from the dust outlet under the filter shell, thereby achieving the absorption of moist dust and preventing moist dust from adhering to the dust suction pipe, thereby preventing dust from accumulating in the dust suction pipe and affecting the dust absorption effect.

[0016] 2. Secondly, when the grid is rotated by the operation of the stepper motor and the filter is switched, as the dial wheel contacts the knocking rod, the knocking rod is pushed up by the protrusion on the dial wheel, and then as the dial wheel no longer contacts the knocking rod, the knocking rod vibrates, thereby knocking the filter shell and the grid. At this time, the ice crystals attached to the filter shell and the grid fall off due to the vibration, and finally enter the dust collecting bag in the ash bag bin from the dust discharge port under the filter shell, avoiding moist dust from adhering to the filter shell and the filter net, thereby reducing the subsequent dust collection effect. At the same time, it also avoids the filter net being discharged from the exhaust pipe by the airflow generated by the fan when collecting dust again after rotating one circle, and failing to absorb and collect dust.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 9 As shown, an embodiment of the present invention provides a dust absorption device for construction and civil engineering roads, comprising a base 1 and a shell 2, wherein the shell 2 is fixedly connected to the base 1, a manifold 12 is fixedly connected to the top surface of the base 1, a dust inlet 11 is symmetrically provided on the side surface of the base 1, the dust inlet 11 is communicated with the manifold 12 through an inclined tube 13, and the top of the manifold 12 penetrates and extends into the shell 2;

[0029] The housing 2 is fixedly connected with a fan 22 and a dust suction pipe 23. The air inlet end of the dust suction pipe 23 is connected with the air outlet of the fan 22. The middle part of the dust suction pipe 23 is a contraction section and is connected with the manifold 12. The air outlet end of the dust suction pipe 23 is fixedly connected with a filter mechanism 3. The outer side surface of the dust suction pipe 23 near the air outlet end is fixedly connected with a plurality of semiconductor chips 24. The outer side surfaces of the plurality of semiconductor chips 24 are fixedly sleeved with a heat conducting ring 25. The heat conducting ring 25 is fixedly sleeved with a heat conducting pipe 26. The heat conducting pipe 26 is fixedly connected with a heat dissipation plate 27.

[0030] The filter mechanism 3 includes a filter shell 31 , in which the heat sink 27 is embedded. A stepper motor 35 is fixedly connected to the inside of the housing 2 . The output shaft of the stepper motor 35 passes through the filter shell 31 and is fixedly sleeved with a filter 4 .

[0031] In the present invention, by setting the dust suction pipe 23, after the fan 22 is started, as the outside air is sucked into the air inlet end of the dust suction pipe 23 by the fan 22, the moist dust around the base 1 floats up under the suction of the fan 22, and at the same time, the dust inlet 11 connected to the contraction end of the dust suction pipe 23 generates suction, thereby sucking in the moist dust suspended nearby, and then driven by the airflow, the moist dust moves to the air outlet end of the dust suction pipe 23. At this time, after the moist dust enters the area where the semiconductor chip 24 is located, the moisture wrapped in the dust crystallizes due to cooling, and after the ice crystals continue to contact the filter 43 along the airflow, the filter 43 captures the ice crystals. When the dust is wrapped by ice crystals and stays on the filter 43, as the stepper motor 35 works, the filter 43 moves to the next position. When the filter 43 moves to the position corresponding to the heat sink 27, the heat generated by the semiconductor chip 24 heats the ice crystals on the filter 43 through the heat sink 27 to melt them. At this time, the water generated by the melting drives the remaining ice crystals and dust to flow, thereby separating from the filter 43 and finally being discharged from the dust outlet 32 ​​under the filter shell 31, thereby achieving the absorption of moist dust and preventing moist dust from adhering to the dust suction pipe 23, thereby preventing dust from accumulating in the dust suction pipe 23 and affecting the dust absorption effect.

[0032] Secondly, when the mesh frame 41 is rotated by the operation of the stepper motor 35 and the filter screen 43 is switched, as the dial wheel 36 contacts the knocking rod 37, the knocking rod 37 is pushed up by the protrusion on the dial wheel 36, and then as the dial wheel 36 no longer contacts the knocking rod 37, the knocking rod 37 vibrates, thereby knocking the filter shell 31 and the mesh frame 41. At this time, the ice crystals attached to the filter shell 31 and the mesh frame 41 fall off due to the vibration, and finally enter the dust collecting bag in the ash bag bin 28 from the dust discharge port 32 under the filter shell 31, so as to prevent moist dust from adhering to the filter shell 31 and the filter screen 43, thereby reducing the subsequent dust collection effect. At the same time, it also prevents the filter screen 43 from being discharged from the exhaust pipe 34 by the airflow generated by the fan 22 when collecting dust again after rotating one circle, and failing to absorb and collect dust.

[0033] like Figures 7 to 9 As shown, the filter 4 includes a grid 41 and a plurality of filter screens 43. The grid 41 is located inside the filter shell 31 and is concentric with the filter shell 31. A plurality of snap-in grooves 42 are provided on the grid 41. The filter screens 43 are movably snap-into the snap-in grooves 42. The diameter of the filter screens 43 is the same as the diameter of the air outlet end of the dust suction pipe 23. The filter screens 43 are made of hydrophobic fibers, which can reduce residual moisture and facilitate the detachment of ice crystals.

[0034] Multiple filters 43 are arranged in a ring shape on the frame 41. When a filter 43 is in a dust collecting state, the separator ring in the filter shell 31 separates the filter 43 from other filters 43, thereby preventing a large amount of airflow generated by the fan 22 from entering the filter shell 31, causing ice crystals to be blown and attached to the filter shell 31 and the frame 41. The airflow interferes with the knocking of the knocking rod 37, affecting the detachment of ice crystals on the filter 43.

[0035] like Figure 7 and Figure 8 As shown, the bottom of the filter shell 31 is fixedly connected with a communicating dust exhaust port 32, the two opposite inner sides of the filter shell 31 are fixedly connected with knocking rods 37, the two sides of the grid 41 are fixedly connected with dial wheels 36, the sides of the dial wheel 36 facing the knocking rod 37 are fixedly connected with protrusions, there are gaps between the knocking rod 37 and the filter shell 31 and the grid 41, the knocking rod 37 is made of elastic material, after the protrusion on the dial wheel 36 squeezes the knocking rod 37 and separates from it, the knocking rod 37 vibrates back and forth and knocks the filter shell 31 and the grid 41.

[0036] As the filter 43 collects dust, ice crystals with dust are attached to the filter 43, and as the stepper motor 35 works, the filter 43 moves to the next position and enters the interior of the filter shell 31. As the rack 41 rotates, when the filter 43 enters the heating position of the heat sink 27, the ice crystals begin to melt. Under the hydrophobic effect of the fibers made of the filter 43, the ice crystals flow downward with the water flow. Then, as the rack 41 continues to rotate, the ice crystals in the flowing state vibrate under the knocking of the knocking rod 37, detach from the filter 43, and then are discharged from the dust outlet 32 ​​below. After that, these ice crystals fall into the dust bag connected to the dust outlet 32 ​​with the dust, thereby achieving adsorption and desorption of dust. The hydrophobic fibers of the filter 43 prevent the ice crystals from being adsorbed on the filter 43 by water.

[0037] like Figures 1 to 5 As shown, an exhaust pipe 34 and a water vapor pipe 33 are fixedly connected to one side of the filter shell 31 away from the dust suction pipe 23, and the other ends of the exhaust pipe 34 and the water vapor pipe 33 both penetrate the outer shell 2 and communicate with the outside.

[0038] When the dust around the base 1 is sucked into the dust suction pipe 23 and captured by the filter 43, the ice crystals begin to melt due to the heat as the filter 43 enters the area heated by the heat sink 27. At this time, the water vapor generated after the melting is discharged along the water vapor pipe 33 above, thereby preventing the humidity in the filter shell 31 from being too high and affecting the service life of the internal components.

[0039] like Figures 1 to 3As shown, a dust bag bin 28 is fixedly opened in the shell 2, a dust discharge port 32 passes through the top surface of the dust bag bin 28 and extends into the dust bag bin 28, a dust collecting bag connected to the dust discharge port 32 is arranged in the dust bag bin 28, and a dust bag door 29 is hinged at the dust bag bin 28.

[0040] As the knocking rod 37 vibrates, the dust and ice crystals leave the filter shell 31 through the dust outlet 32 ​​and eventually fall into the dust bag in the dust bag bin 28. At this time, the ice crystals in the dust bag will moisten the dust bag after melting, so that the dust that subsequently falls into the dust bag will be absorbed by the wet dust bag, thereby preventing the dust inside from flying around and polluting the surrounding environment again under the operation of the staff when replacing the dust bag.

[0041] like Figures 1 to 3 As shown, an inspection door 21 is hinged on the rear side of the housing 2, and a plurality of casters 14 are fixedly connected to the bottom surface of the base 1, so that the device can be moved according to actual needs.

[0042] Working principle:

[0043] When using the device to absorb dust on a construction site, first push the device to the corresponding position, then turn on the switch of the fan 22, so that the fan 22 provides airflow into the dust suction pipe 23, and then under the action of atmospheric pressure, the moist dust floating around the base 1 is sucked into the dust suction pipe 23 and moves toward the filtering mechanism 3 along with the airflow. The fan 22 attracts the surrounding air, which enhances the air flow around the device, so that the moist dust nearby can move toward the device faster and be sucked into the dust suction pipe 23.

[0044] As the wet dust enters the area where the semiconductor wafer 24 is located, the water droplets around the wet dust are cooled and crystallized, and then contact the filter 43 driven by the airflow, and are captured by the filter 43. At this time, clean air is discharged from the exhaust pipe 34.

[0045] As the fan 22 works for a certain period of time, a certain amount of ice crystals accumulate on the filter 43. At this time, the stepper motor 35 works and rotates the set angle, so that the filter 43 that captures the ice crystals enters the filter shell 31. At this time, the heat sink 27 heats the air in the filter shell 31. When the filter 43 is adjacent to the heat sink 27, the heat emitted by the heat sink 27 will heat the ice crystals, causing the ice crystals to begin to melt, and the ice crystals will flow under the drive of water, so that the ice crystals move to the bottom of the filter shell 31. Then, as the grid 41 continues to rotate, the vibration and knocking of the knocking rod 37 cause the ice crystals to fall off the filter 43, and then enter the dust bag in the ash bag bin 28 along the dust outlet 32 ​​below.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
