Abstract
Description
Technical Field
[0001] The utility model relates to an environmentally friendly dust removal device for building construction, belonging to the technical field of building construction dust removal. Background Art
[0002] Construction refers to the construction work carried out on a construction site, including foundation engineering, structural engineering, building decoration engineering, installation engineering and other aspects. During the construction process, safe production is of vital importance. It is related to the safety of construction workers, the assurance of project quality and the social responsibility of the enterprise. Various construction dusts are often emitted during the construction production process, which will damage the working air environment and endanger the health of operating employees. In order to control and treat construction dust, improve the operating air environment of construction sites and prevent air pollution, it is necessary to understand the source of construction dust and its hazards.
[0003] However, the existing construction dust removal device has the following deficiencies and defects during use:
[0004] 1. When dealing with dust generated by construction, although the dust can be sucked into the dust collection box for spraying and dust reduction treatment, after the dust is sucked into the dust collection box, the existing dust collection boxes do not perform point-to-point spraying treatment, that is, several sprinkler heads are hung on the top of the dust collection box, and the sprinkler heads spray water mist into the dust collection box over a large area to achieve dust reduction. However, such spraying is not comprehensive. Due to the large gaps between adjacent sprinkler heads, a small amount of dust will be scattered in the gaps between the sprinkler heads and the pipe connections, and the dust cannot be effectively sprayed and dusted there. It is then discharged into the air again from the exhaust pipe, resulting in the inability to completely clean the dust sucked into the dust collection box.
[0005] 2. After the dust is removed, a large amount of spray wastewater will be generated. The existing treatment method is to discharge it directly into the sewer without filtering and reusing the spray wastewater, resulting in a large amount of water loss during dust removal, which increases the dust removal cost. Utility Model Content
[0006] The technical problem to be solved by the utility model is to provide an environmentally friendly dust removal device for construction, which solves the technical problems that dust inside the existing dust removal box easily enters the gap between the spray heads, the spray dust removal effect is poor, and the wastewater cannot be effectively utilized.
[0007] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:
[0008] An environmentally friendly dust removal device for construction includes: a dust removal box, one end of which is provided with a feed pipe extending into the dust removal box for feeding dust into the dust removal box;
[0009] A spray sealing assembly is provided in the dust removal box. The extended end of the feed pipe passes through the spray sealing assembly and extends to the outside of the spray sealing assembly. The spray sealing assembly includes a plurality of spray heads arranged in intervals, and seals are filled between adjacent spray heads.
[0010] The filter assembly is connected to the dust removal box and is located in the direction of dust settling, and is used to filter the wastewater generated by the spraying;
[0011] The filter assembly is connected to the spray seal assembly through a pipeline and is used to provide a water source for the spray seal assembly.
[0012] Furthermore, the spray seal assembly further includes:
[0013] A collection box is mounted in the dust removal box, and the feed pipe extends into the collection box;
[0014] a water tank connected to the collection tank and the filter assembly and capable of supplying water to the collection tank;
[0015] The sealing member is a partition, which is fixed in the collection box and arranged parallel to the radial direction of the feed pipe;
[0016] The partition is provided with a spray hole corresponding to the spray head, and the spray is placed in the spray hole and sealed;
[0017] The diversion pipe is installed in the collection box and connected to the water tank through a pipeline.
[0018] The spray sealing assembly can be used to spray the collected dust point-to-point to reduce dust, which can prevent the dust from entering the gaps between the spray heads, and the dust entering the dust removal box will be treated more cleanly, avoiding secondary discharge of dust to pollute the air.
[0019] Furthermore, the collection box is connected to an exhaust pipe that extends out of the dust box and is sealed to the dust box. A dust cover is threaded onto the exhaust pipe. The dust cover has a mesh structure that allows air to flow in and out while preventing dust particles from passing through. This ensures that the internal and external pressures of the dust box are equal during the dust removal process, preventing excessive internal pressure from damaging internal components.
[0020] Furthermore, one end of the water tank is connected to a drain pipe and a water inlet pipe, respectively. The drain pipe and the water inlet pipe are arranged parallel to each other in the direction of dust settling, and a sealing cap is threadedly installed on the drain pipe and the water inlet pipe. When the water in the water tank is recycled multiple times or has an odor, the sealing cap at the outer end of the drain pipe is opened to drain the recycled water in the water tank. The sealing cap at the outer end of the water inlet pipe is then opened to connect the external water pipe to refill the water tank.
[0021] Furthermore, the filter assembly includes:
[0022] The filter box has two ends connected to the dust removal box spray sealing assembly;
[0023] Multi-stage filter assemblies are arranged in intervals along the direction of dust settling and are slidably connected to the inner wall of the filter box. The multi-stage filter assemblies can absorb dust in stages, effectively preventing dust from escaping.
[0024] Furthermore, the multi-stage filter assembly includes: three pull-out plates arranged at intervals along the direction of dust settling, and the three pull-out plates are, in order along the direction of dust settling, a filter pull-out plate, a coarse gauze pull-out plate, and a fine gauze pull-out plate;
[0025] A limiting groove is provided on the inner wall of the filter box, and the pull-out plate is placed in the limiting groove and slides in a direction perpendicular to the dust settling direction.
[0026] Furthermore, a baffle is provided on the pull-out plate, and iron sheets are embedded at both ends of the baffle. A magnetic sheet is provided at a position corresponding to the iron sheet on the filter box. When the magnetic sheet is adsorbed on the iron sheet, the pull-out plate is limited to the limiting groove and cannot slide out.
[0027] Furthermore, the feed pipe is connected to a dust suction fan, and a dust suction duct is connected to the end of the dust suction fan opposite to the feed pipe. One end of the dust suction duct is connected to a collection hood for collecting dust and guiding it into the feed pipe. The dust suction fan directly sucks dust from the vicinity of the collection hood into the dust removal box, thereby improving the efficiency of dust collection.
[0028] The beneficial effects of the utility model are:
[0029] (1) The spray sealing assembly of the utility model can be used to spray and reduce dust collected point by point, that is, it can prevent dust from penetrating into the gaps between the spray heads and the pipe connections within the gaps, and can clean the dust entering the dust removal box, thereby improving the spray dust removal capability and preventing dust from being discharged again to pollute the air.
[0030] (2) The filter assembly of the utility model can recycle and reuse the waste water after spraying, thus avoiding the waste of water resources and reducing the cost of dust suppression. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Example
[0044] The existing construction dust removal device has the following deficiencies and defects during use:
[0045] 1. When dealing with dust generated by construction, although the dust can be sucked into the dust collection box for spraying and dust reduction treatment, after the dust is sucked into the dust collection box, the existing dust collection boxes do not perform point-to-point spraying treatment, that is, several sprinkler heads are hung on the top of the dust collection box, and the sprinkler heads spray water mist into the dust collection box over a large area to achieve dust reduction. However, such spraying is not comprehensive. Due to the large gaps between adjacent sprinkler heads, a small amount of dust will be scattered in the gaps between the sprinkler heads and the pipe connections, and the dust cannot be effectively sprayed and dusted there. It is then discharged into the air again from the exhaust pipe, resulting in the inability to completely clean the dust sucked into the dust collection box.
[0046] 2. After the dust is removed, a large amount of spray wastewater will be generated. The existing treatment method is to discharge it directly into the sewer without filtering and reusing the spray wastewater, resulting in a large amount of water loss during dust removal, which increases the dust removal cost.
[0047] Based on this, in order to solve the technical problems that dust easily enters the gap between the above-mentioned spray heads, dust cannot be effectively sprayed and removed, and dust removal wastewater cannot be used, this embodiment provides an environmentally friendly dust removal device for construction, such as Figures 1-6As shown, it includes: a rectangular dust box 1, a mobile base 101, a water tank 102, a spray seal assembly, and a filter assembly. The mobile base 101 is fixedly mounted to the bottom of the dust box 1 via a support rod, the water tank 102 is mounted on top of the mobile base 101, the spray seal assembly is installed inside the dust box 1 to collect and remove dust generated during construction, and the filter assembly is installed on top of the water tank 102 to filter and collect the water used for spraying and dust reduction.
[0048] In some embodiments, as Figure 1-Figure 2 As shown, a dust collecting fan 103 is installed on the top of the dust collecting box 1, a dust collecting air duct 104 is installed on one side of the outer end of the dust collecting fan 103, a collection hood 105 is installed on one end of the dust collecting air duct 104, and a feeding pipe 106 is installed on the other side of the dust collecting fan 103. The feeding pipe 106 passes through the dust collecting box 1 and the collection box 107 and extends to the bottom of the partition 108. When the dust collecting box 1 is in use, it is moved to the construction area by the movable base 101 at the bottom of the dust collecting box 1, and the dust collecting fan 103 is started to generate suction to the dust collecting air duct 104 and the collection hood 105, so that the collection hood 105 sucks in the dust generated in the construction area, and discharges it into the collection box 107 of the dust collecting box 1 through the dust collecting fan 103 and the feeding pipe 106, and then the dust is collected inside the dust collecting box 1 for processing.
[0049] In some embodiments, as Figure 1-Figure 3 As shown, the spray sealing assembly includes: a collecting box 107 installed inside the dust removal box 1, a partition 108 installed inside the collecting box 107, a plurality of spray holes 109 opened on the top of the partition 108, a diversion pipe 110 installed on the top of the partition 108, a nozzle 111 installed at the bottom of the diversion pipe 110 and connected to the plurality of spray holes 109, a water pump 112 installed on one side of the outer end of the water tank 102, a water supply pipe 113 installed on the outer end of the water pump 112, and the water supply pipe 113 passes through the dust removal box 1 and the collecting box 107 and is connected to the diversion pipe 110. When collecting dust, the collecting box 107 is separated by the partition 108, and the feed pipe 106 runs through the bottom of the partition 108, so that the collected dust is gathered at the bottom of the partition 108, and the dust is discharged upward with the air, so that the dust is spread upward around the multiple spray holes 109. At this time, the water pump 112 is started to work, and the water pump 112 pumps out the water inside the water tank 102, and transports it to the diversion pipe 110 through the water pipe 113, and then passes through the diversion pipe 11 0 is diverted to multiple nozzles 111. Since the nozzles 111 correspond one-to-one to the spray holes 109, point-to-point spraying can be formed. When the nozzles 111 spray water mist downward, the water mist is sprayed from the spray holes 109 to the bottom of the partition 108, and will be scattered at multiple spray holes 109 for spraying and dust reduction. Such a structural setting can perform point-to-point spraying and dust reduction on the collected dust, and can completely clean the dust entering the dust removal box 1, avoiding secondary discharge of dust to pollute the air.
[0050] In some embodiments, as Figure 2 and Figure 6 As shown, an exhaust pipe 3 is installed on one side of the outer end of the collection box 107, and the exhaust pipe 3 passes through the outside of the dust removal box 1. A dust shield 301 is threadedly installed on the outer end of the exhaust pipe 3. After the dust is removed from the collection box 107, the air entering the collection box 107 can be discharged from the dust removal box 1 through the exhaust pipe 3. During use, the exhaust pipe 3 can be shielded from dust by the dust shield 301. The dust shield 301 uses a 600-mesh screen to isolate fine dust.
[0051] In some embodiments, as Figure 2 、 Figure 4 and Figure 5 As shown, the filter assembly includes: a filter box 2 installed on the top of the water tank 102, the top of the filter box 2 is connected to the collecting box 107, and the collecting box 107, the filter box 2 and the water tank 102 are communicated, three pull-out plates 201 are arranged inside the filter box 2, and the three pull-out plates 201 are respectively a filter pull-out plate 201, a coarse yarn pull-out plate 201 and a fine yarn pull-out plate 201 from top to bottom, limit grooves 202 are opened on both sides of the inside of the filter box 2 and are slidably connected to the pull-out plates 201, and a baffle 203 is installed on the outer end of the pull-out plate 201. When spraying dust to reduce dust, since the collection box 107, the filter box 2 and the water tank 102 are connected, the sprayed wastewater can fall from the inside of the collection box 107 into the filter box 2, and the wastewater will pass through three pull-out plates 201 in sequence. The top pull-out plate 201 has a filter screen inside, the middle layer is coarse gauze, and the bottom layer is fine gauze. When water is sprayed on dust, it will come into contact with the dust to form mud particles. The mud particles can be filtered through the upper pull-out plate 201, and the large mud can be filtered when passing through the middle layer, and the fine mud can be filtered when passing through the lower layer, thereby filtering out the mud particles and mud in the wastewater. The filtered wastewater drips from the pull-out plate 201 and is collected inside the water tank 102, so that the wastewater after spraying can be recycled and reused, avoiding waste of water resources and reducing the cost of dust reduction.
[0052] In some embodiments, as Figure 4-Figure 5As shown, iron sheets 204 are embedded and installed on both sides of the inner wall of the baffle 203, and magnetic sheets 205 are embedded and installed on both sides of the outer wall of the filter box 2, and the iron sheets 204 and the magnetic sheets 205 are magnetically fixed. When the pull-out plate 201 is used, the box door on the outside of the filter box 2 is opened, and the pull-out plate 201 is respectively inserted into the limiting grooves 202 on both sides of the inside of the filter box 2. After being fully inserted, the baffles 203 on the outer ends of the pull-out plate 201 will fit tightly with the outer wall of the filter box 2. At this time, the iron sheets 204 on both sides of the inner wall of the baffle 203 and the magnetic sheets 205 on both sides of the outer wall of the filter box 2 are magnetically fixed together, so that the pull-out plate 201 is firmly placed inside the limiting groove 202. When the pull-out plate 201 needs to be cleaned, the box door on the outside of the filter box 2 is opened, and the handle at the outer end of the baffle 203 is directly pulled out from the inside of the limiting groove 202 for cleaning.
[0053] In some embodiments, as Figure 1-Figure 2 As shown, a drain pipe 4 is installed at the bottom of the outer end of the water tank 102, and a water inlet pipe 401 is installed at the top of the outer end of the water tank 102. A sealing cap 402 is threadedly installed on the outer ends of the drain pipe 4 and the water inlet pipe 401, and an observation window 403 is installed on the top of the outer side of the water tank 102. When the water inside the water tank 102 is recycled many times or has an odor, the sealing cap 402 at the outer end of the drain pipe 4 is opened to drain the recycled water inside the water tank 102, and then the sealing cap 402 at the outer end of the water inlet pipe 401 is opened to connect the external water pipe to refill water into the water tank 102. During the water filling process, the water level can be observed through the observation window 403 on the outer side of the water tank 102. When the water level is at the top of the water tank 102, the water filling can be stopped.
[0054] It should be noted that if Figure 1 As shown, a device box 5 is installed at the bottom of the outer side of the water tank 102, a control switch 501 is installed inside the device box 5, and a power cord connected to the control switch 501 is installed at the outer end of the device box 5. When the dust suction fan 103 and the water pump 112 are in use, the dust suction fan 103 and the water pump 112 are respectively connected to the control switch 501 in the device box 5 through wires, while the other side of the control switch 501 is connected to the power cord. A plug is installed at the outer end of the power cord, which can be inserted into an external socket to turn on the power supply, so that the control switch 501, the dust suction fan 103 and the water pump 112 can be powered on and used normally. The control program involved in the present utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.
[0055] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
