[0002] With the acceleration of the urbanization process, building construction activities have become increasingly frequent, and the problem of dust pollution generated at building construction sites has also become increasingly serious. During the building construction process, a large amount of dust is generated in links such as concrete mixing, sand and gravel transportation, and wood processing. These dusts not only pose a threat to the health of construction workers, but also cause pollution to the surrounding environment. Therefore, how to effectively handle the dust generated during building construction has become an urgent technical problem to be solved.

[0003] Traditional air dust removal and purification devices usually adopt a single dust removal method, such as cyclone dust removal, bag dust removal or adsorption purification.

Specific implementation mode

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0045] Embodiment 1

At least one of the upstream connection pipe 111 and the downstream connection pipe 112 is assembled in the splicing frame 1. The processing unit includes an air inlet module 2, an exhaust module 3, and a cyclone dust removal module 4, a bag dust removal module 5, an adsorption purification module 6, and an immersion treatment module 7 that are arranged between the air inlet module 2 and the exhaust module 3 and are selectively assembled.

[0047] It further includes a drive assembly 8. The drive assembly 8 includes a drive motor 81, a guide rod 82, a spline shaft 83, and a docking assembly 84. The guide rod 82 and the spline shaft 83 are arranged in parallel and along the arrangement direction of the splicing frame 1. The drive motor 81 is power-connected to the spline shaft 83, and multiple groups of docking assemblies 84 are assembled on the guide rod 82 and the spline shaft 83.

[0048] The docking assembly 84 includes a sliding bracket 841, a first bevel gear 842, a second bevel gear 843, and a locking groove 844. The sliding bracket 841 is slidably connected with the guide rod 82. The first bevel gear 842 and the second bevel gear 843 are rotatably installed on the sliding bracket 841 and maintained in a meshing arrangement. The axis of the first bevel gear 842 is slidably connected with the spline shaft 83, the axis of the second bevel gear 843 is perpendicular to the spline shaft 83, and the locking groove 844 is coaxially fixed with the second bevel gear 843.

[0049] The cyclone dust removal module 4, the bag dust removal module 5, the adsorption purification module 6, the water treatment module 7, and the exhaust module 3 are all equipped with locking joints 85, and power transmission can be achieved when the locking joints 85 are nested and locked with the locking grooves 844 at the corresponding positions.

[0050] The setting of the splicing frame 1 can ensure that each module can be stably installed therein, and realize the connection combination with the matching upstream connecting pipe 111 and the downstream connecting pipe 112, and at the same time can realize the docking combination between the splicing frames 1, so as to realize the stable assembly of the powder selection and dust removal module, the bag dust removal module 5, the adsorption purification module 6, and the water treatment module between the air inlet module 2 and the exhaust module 3, and form an air dust removal and purification device with a specific processing process.

[0051] After the modules are arranged and assembled according to the processing sequence, the downstream pipe 112 of the front module is connected to the upstream pipe 111 of the rear module to ensure that the processed air is stably transmitted along the arrangement sequence and complete the corresponding processing task.

[0052] The dust generated at construction sites is mostly construction materials that diffuse into the surrounding air in the form of particles, such as concrete, gravel, ground soil, wood chips, etc.

[0053] Therefore, the air and the granular building materials diffused therein are extracted through the air inlet module 2, and transported backward to the cyclone dust removal module 4, the bag dust removal module 5, the adsorption purification module 6, and the water treatment module 7 according to the correspondingly spliced upstream connecting pipe 111 and the downstream connecting pipe 112. After the dust removal and purification treatment, the air is discharged back into the environment by the exhaust module 3.

[0054] The cyclone dust removal module 4, the bag dust removal module 5, the adsorption purification module 6, and the immersion treatment module 7 can be increased or decreased according to the specific type of dust to be treated, so as to improve the pertinence and applicability of the environmental treatment on the construction site.

[0055] Example 2

[0056] See also Figures 1-3In order to ensure that the processing units arranged and combined in a set order can be stably loaded and moved at the construction site, and stably operate under the power support provided by the drive assembly 8, the following technical solution is provided.

[0057] It also includes a load-bearing frame 9, both sides of which are equipped with support wheels 91, and the splicing frame 1 is fixedly installed on the load-bearing frame 9 in a detachable manner. A clearance groove 92 is opened on the load-bearing frame 9, and the guide rod 82, the spline shaft 83, and the docking assembly 84 are all arranged below the clearance groove 92 and arranged along the clearance groove 92. The cyclone dust removal module 4, the bag dust removal module 5, the adsorption purification module 6, the immersion treatment module 7, and the exhaust module 3 pass through the clearance groove 92 and are dynamically connected to the docking assembly 84.

[0058] The bottom plate of each load-bearing frame 9 is fixed to the load-bearing frame 9 by bolts to facilitate its disassembly, assembly and replacement. The setting of the support wheels 91 can stably support the load-bearing frame 9 and facilitate the transfer of the load-bearing frame 9 and the processing unit assembled thereon at the construction site.

[0059] The provided clearance slots 92 can ensure that each processing unit is stably assembled on the supporting frame 9 and realizes power connection with the driving assembly 8 .

[0060] Rubber pads 12 can be installed on the front and rear sides of the splicing frame 1. When two adjacent groups of splicing frames 1 are assembled, the pads 12 thereon remain in close contact with each other to avoid direct rigid contact between the splicing frames 1. At the same time, the impact of vibration on surrounding processing units can be reduced when the processing units are running.

[0061] Two sets of devices arranged side by side can be mounted on the load-bearing frame 9 to improve the air treatment efficiency at the construction site.

[0062] In order to ensure that the drive assembly 8 can be stably assembled on the supporting frame 9, and to ensure that the upstream pipe 111 and the downstream pipe 112 of the adjacent splicing frames 1 can be matched and connected to realize air transmission, the following technical solution is provided.

[0063] The bottom of the carrier frame 9 is fixedly connected with assembly plates 93 respectively arranged at both ends of the clearance slot 92, the guide rod 82 is fixedly installed between the two groups of assembly plates 93, the spline shaft 83 is rotatably installed between the two groups of assembly plates 93, the drive motor 81 is fixedly installed on one group of assembly plates 93, the output shaft of the drive motor 81 is fixedly connected with a drive bevel gear 811, and the end of the spline shaft 83 is fixedly connected with a transmission bevel gear 831 that keeps meshing with the drive bevel gear 811;

[0064] The end of the upstream pipe 111 is fixedly connected with a plug-in pipe 113 , and the plug-in pipe 113 is nested and plugged into the inner side of the adjacent downstream pipe 112 . Flanges are installed at the ports of the upstream pipe 111 and the downstream pipe 112 .

[0065] The setting of the assembly plate 93 can ensure the stable installation of the driving motor 81, the guide rod 82 and the spline shaft 83 in the driving assembly 8. The power generated when the driving motor 81 is working can drive the spline shaft 83 to operate stably through the combination of the driving bevel gear 811 and the transmission bevel gear 831.

[0066] The combined action of the guide rod 82 and the spline shaft 83 can ensure that the docking assembly 84 can slide stably along the axial direction, so that the locking groove 844 therein can achieve power connection with the corresponding processing unit. The combination of the spline shaft 83 and the No. 1 bevel gear 842 can ensure that power is always transmitted to the docking assembly 84 at the corresponding position, and then drive the corresponding processing unit to operate stably through the combination of the No. 1 transmission bevel gear 831, the No. 2 transmission bevel gear 831, and the locking groove 844.

[0067] When the upstream pipe 111 and the downstream pipe 112 on two adjacent groups of splicing frames 1 are assembled, the plug-in pipe 113 on the upstream pipe 111 can be plugged into the downstream pipe 112, and the two groups of flanges are fixedly connected by a bolt assembly to realize the combination of the upstream pipe 111 and the downstream pipe 112. A sealing strip can also be installed at the interface position to ensure the sealing effect of the connection position of the two groups of pipes.

[0068] Example 3

[0069] See also Figures 4-6 In order to ensure that the air supply module can be stably assembled on the corresponding splicing frame 1 and achieve the purpose of stably extracting and transmitting the air in the construction environment, the following technical solution is provided.

[0070] The air inlet module 2 includes an air collecting hood 21 and a blower 22 fixedly installed in the corresponding splicing frame 1. The air collecting hood 21 is connected to the air inlet of the blower 22 through an air inlet pipe 221, and the air outlet of the blower 22 is connected to the corresponding downstream connecting pipe 112 through an exhaust pipe 222.

[0071] The negative pressure generated by the blower 22 when running at high speed can extract the air and dust from the construction site, which are collected by the air collecting hood 21 and transmitted to the corresponding downstream connecting pipe 112 through the air inlet pipe 221 and the exhaust pipe 222.

[0072] A vertical plate 13 is welded on the splicing frame 1 on which the air inlet module 2 is assembled, and a barrel opening for assembling the air collecting hood 21 is opened on the vertical plate 13, so that the air collecting hood 21 can be stably installed on the vertical plate 13 with the opening, and the base of the blower 22 is fixedly installed on the bottom plate of the splicing frame 1.

[0073] To ensure that the exhaust air module 3 can be stably assembled on the splicing frame 1 and enable the air after dust removal and purification of each processing unit on the front side to be evenly discharged into the construction environment, the following technical solutions are provided.

[0074] The exhaust air module 3 includes a rotating sleeve 31, an exhaust hood 32, a drive shaft A 33, a crank 34, and a connecting rod 35. The rotating sleeve 31 is rotatably installed on the corresponding splicing frame 1 and rotates around the vertical axis. The exhaust hood 32 is fixedly connected to the bottom of the rotating sleeve 31 and is arranged horizontally. The top of the rotating sleeve 31 is rotatably connected to the corresponding upstream connecting pipe 111. The drive shaft A 33 is rotatably installed on the splicing frame 1 and is arranged vertically. The upper and lower ends of the drive shaft A 33 are respectively fixedly connected with a crank 34 and a locking joint 85. The two ends of the connecting rod 35 are respectively hinged to the crank 34 and the rotating sleeve 31.

[0075] When the power of the drive assembly 8 drives the drive shaft A 33 and the crank 34 through the combination of the locking groove 844 and the locking joint 85, the drive can drive the rotating sleeve 31 and the exhaust hood 32 to swing periodically within a specific angle range through the connecting rod 35. Since the rotating sleeve 31 is rotatably connected to the corresponding upstream connecting pipe 111, the air transmitted by the upstream connecting pipe 111 can always be conveyed to the exhaust hood 32 through the rotating sleeve 31 during the swinging process of the rotating sleeve 31, and then the exhaust hood 32 discharges the air after dust removal and purification treatment into the surrounding environment.

[0076] An assembly seat 14 is also fixedly connected in the splicing frame 1 for assembling the exhaust air module 3. The drive shaft A 33 and the rotating sleeve 31 are both rotatably installed on the assembly seat 14 to achieve their stable installation in the splicing frame 1.

[0077] Embodiment 4

[0078] Please refer to Figures 7-10 , to ensure that the cyclone dust removal module 4 can be stably assembled in the corresponding splicing frame 1 and effectively remove dust from the air entering it, the following technical solutions are provided.

[0079] The cyclone dust removal module 4 includes a cyclone dust collector 41, a drive shaft B 42, a spiral conveyor blade A 43, and a fan impeller 44. The cyclone dust collector 41 is fixedly installed in the splicing frame 1. The drive shaft B 42 is rotatably installed at the axial position of the cyclone dust collector 41. The tangential connecting pipe 411 of the cyclone dust collector 41 is connected to the corresponding upstream connecting pipe 111, and the axial connecting pipe 412 of the cyclone dust collector 41 is connected to the corresponding downstream connecting pipe 112. The drive shaft B 42 is fixedly connected with a fan impeller 44, a spiral conveyor blade A 43, and a locking joint 85 arranged from top to bottom. The fan impeller 44 is arranged in the axial connecting pipe 412, and the spiral conveyor blade A 43 is arranged in the ash discharge pipe 413 at the bottom of the cyclone dust collector 41.

[0080] The dusty air tangentially enters the cyclone dust collector 41 at a relatively high speed through the tangential connection pipe 411 and can form a rotating air flow. When it rotates at a high speed inside the body, the dust is thrown towards the inner wall under the action of centrifugal force and separated from the gas. The dust thrown towards the inner wall slides down along the inner wall of the conical cylinder structure and finally falls into the ash discharge pipe 413 at the bottom. The separated gas forms an upward inner swirling flow in the center of the cyclone dust collector 41 and is transmitted to the corresponding downstream connection pipe 112 through the axial connection pipe 412.

[0081] The transmission shaft B42 receives power under the action of the docking assembly 84 and the locking joint 85 and drives the screw conveyor blade and the fan impeller 44 to operate. The screw conveyor blade A43 can apply a downward force to the dust collected in the ash discharge pipe 413 and discharge and collect it outside the lateral opening at the bottom of the ash discharge pipe 413, thereby ensuring that the ash discharge pipe 413 can continuously collect the dust separated by the cyclone dust collector 41. The operating fan impeller 44 can apply a force to the separated air flow to accelerate the discharge of the separated air flow from the axial connection pipe 412.

[0082] To ensure that the bag dust removal module 5 can be stably assembled in the corresponding splicing frame 1 and effectively remove dust from the entering air, the following technical solutions are provided.

[0083] The bag dust removal module 5 includes an installation sleeve 51, a connection cover 52, a dust removal bag 53, a dust discharge pipe 54, a transmission shaft C55, a cleaning brush 56, and a screw conveyor blade B57. The connection cover 52 and the dust discharge pipe 54 are respectively fixed to the upper and lower ends of the installation sleeve 51 and are arranged coaxially. The two ends of the dust removal bag 53 are respectively fixedly connected to the connection cover 52 and the dust discharge pipe 54. The installation sleeve 51 is connected to the corresponding downstream connection pipe 112, and the connection cover 52 is connected to the corresponding upstream connection pipe 111. The transmission shaft C55 is rotatably installed at the center of the installation sleeve 51. The cleaning brush 56, the screw conveyor blade B57, and the locking joint 85 are fixedly connected to the transmission shaft C55 in a top-down arrangement. The cleaning brush 56 is arranged in a spiral shape and fits the inner wall of the dust removal bag 53. The screw conveyor blade B57 is arranged in the dust discharge pipe 54.

[0084] The bottom of the installation sleeve 51 is designed as an inverted cone, which is convenient for collecting the intercepted dust and can cooperate with the connection cover 52 to ensure the stable installation of the dust removal bag 53 in the installation sleeve 51. The connection cover 52 is fixedly connected to the installation sleeve 51 in a detachable manner, which is convenient for removing it to replace the internal dust removal bag 53.

[0085] The dust removal cloth bag 53 can divide the installation sleeve 51 into inner and outer chambers. The air transmitted from the upstream can directly enter the dust removal cloth bag 53 through the connecting cover 52. After being filtered by the dust removal cloth bag 53, the filtered air can enter the outer chamber and then be transmitted downstream through the downstream connection pipe 112, while the carried dust is intercepted on the inner wall of the dust removal cloth bag 53.

[0086] The cleaning brush 56 is also fixedly installed on the transmission shaft C55 through the spiral arrangement of the connecting brackets 58. The power of the driving assembly 8 drives the transmission shaft C55, the cleaning brush 56, and the spiral conveyor blade B57 to rotate synchronously through the combination of the locking groove 844 and the locking joint 85. The cleaning brush 56 can sweep the dust attached to the inner wall of the dust removal cloth bag 53 and finally fall into the dust discharge pipe 54 below, while the spiral conveyor blade B57 can exert a downward force on the dust collected in the dust discharge pipe 54, and finally be discharged and collected from the lateral opening at the bottom of the dust discharge pipe 54 to ensure the permeability of the dust removal cloth bag 53 and the effect of continuously treating dust.

[0087] It should be noted that the cyclone dust removal module 4 is used to clean larger particles of dust, while the bag dust removal module 5 is used to clean smaller particles of dust. When the two are used simultaneously, the bag dust removal module 5 needs to be assembled on the downstream side of the cyclone dust removal module 4.

[0088] Embodiment 5

[0089] Please refer to Figures 11-14 , in order to ensure that the adsorption and purification module 6 can be stably assembled in the corresponding splicing frame 1 and realize the adsorption and purification treatment of the air entering it, the following technical solutions are provided.

[0090] The adsorption and purification module 6 includes a processing sleeve 61, a connecting pipe 62, a transmission shaft D63, and stirring blades 64. The connecting pipe 62 is fixedly connected to the bottom center of the processing sleeve 61 and is connected to the corresponding upstream connection pipe 111. The top of the processing sleeve 61 is connected to the corresponding downstream connection pipe 112. A plurality of partition plates 611 are fixedly connected in the processing sleeve 61. The partition plates 611 divide the processing sleeve 61 into multiple adsorption chambers 612. The transmission shaft D63 is rotatably installed at the center of the processing sleeve 61 and penetrates through each layer of adsorption chamber 612. Stirring blades 64 and locking joints 85 are fixedly connected to the transmission shaft D63, and stirring blades 64 are distributed in each layer of adsorption chamber 612.

[0091] The adsorption chamber 612 is filled with activated carbon or other adsorption materials. Through holes are provided on each layer of partition plate 611 to intercept the adsorption materials while ensuring that the air can pass through stably from top to bottom. When the air with fine dust or harmful substances passes through each layer of adsorption chamber 612 from bottom to top, the adsorption materials therein can effectively adsorb it.

[0092] During the operation of the drive assembly 8 driving the transmission shaft D63 and the stirring blades 64 thereon through the locking groove 844 and the locking joint 85, the adsorption material can be evenly stirred to improve the adsorption efficiency of the adsorption material and achieve the purpose of efficiently purifying the air.

[0093] To ensure that the water immersion treatment module 7 can be stably assembled in the corresponding splicing frame 1 and introduce the transmitted air into the water, so that the carried fine particles aggregate and precipitate in the water to achieve the purification of the air, the following technical solutions are provided for this.

[0094] The water immersion treatment module 7 includes a water storage cylinder 71, a sediment pipe 72, a sludge discharge pipe 73, a transmission shaft E74, and a spiral conveyor blade C75. The sludge discharge pipe 73 is connected to the center of the bottom of the water storage cylinder 71, and the corresponding upstream connection pipe 111 extends to the bottom of the water storage cylinder 71. The top of the water storage cylinder 71 is connected to the corresponding downstream connection pipe 112. The sludge discharge pipe 73 is fixedly installed at the center of the water storage cylinder 71 and extends into the sediment pipe 72. The transmission shaft E74 is rotatably installed in the sludge discharge pipe 73, and a spiral conveyor blade C75 and a locking joint 85 are fixedly connected to the transmission shaft E74.

[0095] Clear water covering the upstream connection pipe 111 is added to the water storage cylinder 71, and a flocculant or other chemicals can be added to the clear water. The air transmitted from upstream is transported to the water storage cylinder 71 through the upstream connection pipe 111. After entering the water storage cylinder 71, it is absorbed by the water or forms sediment and deposits in the sediment pipe 72 at the bottom. The connection between the sediment pipe 72 and the water storage cylinder 71 is set as an inverted cone structure, which helps the sediment enter the sediment pipe 72. The purified air rises above the water surface and is discharged from the downstream connection pipe 112 connected to the top of the water storage cylinder 71.

[0096] When the drive assembly 8 drives the transmission shaft E74 and the spiral conveyor blade C75 to operate, the sludge can be output upward from the water storage cylinder 71 through the sludge discharge pipe 73 and collected externally from the opening on the side of the sludge discharge pipe 73.

[0097] It should also be noted that the air discharged from the water storage cylinder 71 contains a certain amount of moisture. To avoid contaminating the adsorption material in the adsorption purification module 6, the water immersion treatment module 7 is usually arranged on the downstream side of the adsorption purification module 6.
