Description

Technical Field

[0001] This application relates to the technical field of environmental protection construction, and particularly relates to a dust removal device for building construction. Background Art

[0002] Dust is an open pollution source that enters the atmosphere due to the dust on the ground being carried by wind, human activities, and other factors. It is an important component of total suspended particulate matter in ambient air. During construction, the fine dust in the powder particles is first separated from the powder particles and carried into the air by air currents, ventilation-induced air flow, and the air flow generated by the rotation of moving parts of equipment. Then, due to the indoor air flow, the dust diffuses, thus completing the process from dust generation to diffusion.

[0003] Existing construction dust removal devices usually use the method of air extraction or air injection to remove dust debris around the construction site. These devices are generally designed with a single pipe section structure. Although they are simple and easy to use, when dealing with dust debris containing a large amount of fibrous materials, problems such as blockage and entanglement are likely to occur. This kind of blockage not only affects the dust removal efficiency of the device but also increases the difficulty of cleaning and maintenance. In addition, fibrous materials are easily adhered to the handle of the device, further affecting the operation efficiency and the service life of the device. Due to these defects, existing construction dust removal equipment shows obvious deficiencies in practical applications, especially when dealing with mixed dust debris, and it is difficult to meet the requirements of high-efficiency and long-lasting dust removal.

[0004] Generally speaking, during the process of building construction dust removal, methods including air extraction and air injection are used to remove nearby dust debris. However, the traditional dust removal head only includes a single pipe section. If the dust debris contains a large amount of fibrous materials, blockage and entanglement at the end are likely to occur. At the same time, this kind of waste debris is also easily adhered to the handle, affecting the actual dust removal efficiency. Summary of the Invention

One end of the air inlet and outlet pipe is installed with a dust debris inlet and outlet pipe mechanism, and multiple electrostatic adsorption mechanisms are arranged outside the dust debris inlet and outlet pipe mechanism. One end of the dust debris inlet and outlet pipe mechanism is installed with a cover mechanism.

[0006] Wherein the dust debris inlet and outlet pipe mechanism includes a double-barrel support base. One end of the double-barrel support base is used to connect to the air inlet and outlet pipe. The top of the double-barrel support base includes an outer support part and an inner support part. A bearing part one is installed on the top of the outer support part of the double-barrel support base. The top of the outer support part is rotatably connected to a support cylinder section one, and an outer cylinder section is fixedly installed on the top of the support cylinder section one.

[0007] A bearing part two is installed at the top of the inner bearing part in the double-barrel support seat. The top of the inner bearing part is rotatably connected to a second support cylinder section. A plurality of spiral fan blades for facing the wind are installed in the second support cylinder section. A plurality of static friction rings are fixedly installed outside the second support cylinder section. The static adsorption mechanism includes a static friction rope. When the static friction rope rubs against the static friction rings, a static adsorption state is formed.

[0008] Preferably, a second connecting pipe section is communicated and provided at the bottom of the double-barrel support seat. A first connecting pipe section is fixedly installed at the bottom of the second connecting pipe section. An air pipe connecting bolt for connecting the air inlet and outlet pipes is fixedly installed at the bottom of the first connecting pipe section.

[0009] Preferably, a plurality of prefabricated longitudinal grooves are formed outside the outer cylinder section. The plurality of prefabricated longitudinal grooves are arranged in a circular distribution. The prefabricated longitudinal groove includes a longitudinal straight groove and a circular clamping groove. A plurality of circular clamping grooves are formed in each longitudinal straight groove, and the circular clamping grooves are used for installing the static adsorption mechanism.

[0010] Preferably, a transmission mechanism is installed between the first support cylinder section and the second support cylinder section. The transmission mechanism includes a bearing part three. The bearing part three is installed at the bottom of the inner cavity of the double-barrel support seat. A support roller shaft is rotatably connected in the double-barrel support seat. A gear block is fixedly installed at the top of the support roller shaft. A first gear groove is formed at the bottom of the second support cylinder section. A second gear groove is formed on the inner wall of the first support cylinder section. The gear block, the first gear groove and the second gear groove are meshed with each other.

[0011] Preferably, the cover body mechanism includes a first cover body section. The first cover body section is installed at the top of the second support cylinder section. A second cover body section is installed at the top of the first cover body section. The second cover body section is arranged in a flared shape. The diameter of the top opening of the second cover body section is larger than the diameter of the outer cylinder section. An air inlet and outlet groove is formed in the middle of the first cover body section and the second cover body section. The air inlet and outlet groove is communicated with the second support cylinder section.

[0012] Preferably, a support seat is installed on the outer wall of the second cover body section. A bearing part four is installed at the bottom of the support seat. The support seat is installed on the top of the outer cylinder section through the bearing part four.

[0013] Preferably, the static adsorption mechanism includes a positioning cylinder. A hollow groove is formed inside the positioning cylinder. A rope section positioning pipe is fixedly installed at one end of the inner cavity of the hollow groove. The static friction rope is fixedly installed in the inner cavity of the hollow groove through the rope section positioning pipe. Positioning panels are installed at both ends of the positioning cylinder. The positioning cylinder is clamped in the circular clamping groove of the prefabricated longitudinal groove through the two positioning panels.

[0014] The technical effects and advantages of the present invention:

[0015] The traditional dust removal head design is prone to causing fibrous materials to adhere to the handle, affecting the dust removal efficiency. In the present invention, an electrostatic friction ring is installed on the second support cylinder section and the outer cylinder section, generating static electricity through friction with the electrostatic friction rope, enabling fibrous materials to be effectively adsorbed, preventing them from clogging the dust extraction equipment or winding around the key parts of the dust removal device, and ensuring the continuous and efficient operation of the equipment;

[0016] Traditional construction dust removal devices usually adopt a single pipe section design, which is prone to low dust removal efficiency due to the clogging or winding of the end by fibrous materials. In the present invention, by designing a double-cylinder support seat, the second support cylinder section and the outer cylinder section can rotate to form an air flow. Combining with the windward effect of the spiral fan blades, the dust removal efficiency is effectively improved. The air flow can better capture and remove dust particles in the air through the spiral fan blades during rotation, achieving a more efficient dust removal effect;

[0017] When traditional dust removal equipment processes mixed dust particles, it is difficult to effectively distinguish fibrous materials from dust, easily leading to equipment blockage. In the present invention, through electrostatic adsorption technology, fibrous materials are adsorbed on the surface of the electrostatic friction rope, while the heavier dust is directly washed away or sucked away by the air flow. This not only effectively realizes classified dust removal, improves the dust removal efficiency, but also protects the normal operation of the equipment and reduces the maintenance frequency;

[0018] The design of the present invention has a high degree of flexibility and adaptability. By replacing or adjusting the materials or structures of the electrostatic friction ring and the electrostatic friction rope, it can adapt to different dust removal requirements. For example, materials more suitable for adsorbing specific types of dust particles can be selected, so that it can be widely applied in various construction environments, significantly enhancing the practical value and market competitiveness of the equipment.

Specific embodiments

[0028] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0029] Please refer to Figure 1-7 , as shown in the figure, a building construction dust removal device provided in this embodiment, such as Figure 1As shown in the figure, it includes an air inlet and outlet pipe 1. Specifically, the air inlet and outlet pipe 1 is used to connect the air inlet and outlet pipes of the air extraction or exhaust equipment, and the air extraction or exhaust equipment is used for construction dust removal. One end of the air inlet and outlet pipe 1 is equipped with a dust and debris inlet and outlet pipe mechanism 2. A plurality of electrostatic adsorption mechanisms 5 are installed on the outer wall of the dust and debris inlet and outlet pipe mechanism 2. One end of the dust and debris inlet and outlet pipe mechanism 2 far from the air inlet and outlet pipe 1 is equipped with a cover mechanism 4. Among them, the dust and debris inlet and outlet pipe mechanism 2 includes a double-barrel support seat 24. One end of the double-barrel support seat 24 is used to communicate with the air inlet and outlet pipe 1. The top of the double-barrel support seat 24 includes an outer bearing part and an inner bearing part. A bearing part one 25 is installed on the top of the outer bearing part of the double-barrel support seat 24. The top of the outer bearing part is rotatably connected with a support cylinder section one 27 through the bearing part one 25. A bearing part two 26 is installed on the top of the inner bearing part of the double-barrel support seat 24. The top of the inner bearing part is rotatably connected with a support cylinder section two 28 through the bearing part two 26. The top of the support cylinder section one 27 is fixedly installed with an outer cylinder section 29. A plurality of spiral fan blades 210 for facing the wind are installed in the inner cavity of the support cylinder section two 28. A plurality of electrostatic friction rings 212 are fixedly installed on the outer wall of the support cylinder section two 28. The electrostatic adsorption mechanism 5 is installed inside the outer cylinder section 29. The electrostatic adsorption mechanism 5 includes an electrostatic friction rope 55. When the electrostatic friction rope 55 rubs against the electrostatic friction ring 212, an electrostatic adsorption state is formed.

[0030] Regarding the spiral fan blades 210, it should be noted that by designing the double-barrel support seat 24, the support cylinder section two 28 and the outer cylinder section 29 can rotate to form an air flow. Combining with the wind-facing effect of the spiral fan blades 210, the dust removal efficiency is effectively improved. The air flow can better capture and remove dust and debris in the air through the spiral fan blades 210 during the rotation process, achieving a more efficient dust removal effect. The air flow is formed by the rotation of the support cylinder section two 28 and the outer cylinder section 29 supported by the double-barrel support seat 24. Combining with the wind-facing effect of the spiral fan blades 210, the classified dust removal efficiency is improved. The air flow captures and removes dust and debris in the air during the rotation process. At the same time, the electrostatic friction ring 212 and the electrostatic friction rope 55 generate static electricity to adsorb fiber-like materials, realizing classified dust removal.

[0031] Among them, a connecting pipe section two 23 is installed at the bottom of the double-barrel support seat 24 in a communicating state. A connecting pipe section one 22 is fixedly installed at the bottom of the connecting pipe section two 23. An air pipe connecting bolt 21 for connecting the air inlet and outlet pipe 1 is fixedly installed at the bottom of the connecting pipe section one 22.

[0032] Furthermore, a plurality of prefabricated longitudinal grooves 211 are formed through the outer wall of the outer cylinder section 29. The plurality of prefabricated longitudinal grooves 211 are arranged in a circular distribution; as Figure 6 shown, the prefabricated longitudinal groove 211 includes a longitudinal straight groove and a circular card slot. A plurality of circular card slots are opened in each longitudinal straight groove, and the circular card slots are used to install the electrostatic adsorption mechanism 5.

[0033] Specifically, a transmission mechanism 3 is installed between the first support cylinder section 27 and the second support cylinder section 28. The transmission mechanism 3 includes a third bearing member 31, and the third bearing member 31 is installed at the bottom of the inner cavity of the double-cylinder support seat 24. A support roller shaft 32 is rotatably connected to the bottom of the inner cavity of the double-cylinder support seat 24 through the third bearing member 31. A gear block 33 is fixedly installed at the top of the support roller shaft 32 by bolts; a first gear groove 34 is formed in the outer wall at the bottom of the second support cylinder section 28, and a second gear groove 35 is formed in the inner wall of the first support cylinder section 27. The gear block 33, the first gear groove 34, and the second gear groove 35 are meshed with each other.

[0034] In the construction dust removal device of the present invention, a transmission mechanism 3 is installed between the first support cylinder section 27 and the second support cylinder section 28. The support roller shaft 32 is rotatably connected through the third bearing member 31. The gear block 33 is fixedly installed at the top of the support roller shaft 32 by bolts. The gear block 33 is meshed with the first gear groove 34 of the second support cylinder section 28 and the second gear groove 35 of the first support cylinder section 27 to achieve linkage rotation, enhance the air flow effect, and improve the dust removal efficiency.

[0035] Further, the hood mechanism 4 includes a first hood section 41. The first hood section 41 is installed at the top of the second support cylinder section 28 by bolts. A second hood section 42 is installed at the top of the first hood section 41 by bolts. The second hood section 42 is arranged in a flared shape, and the diameter of the top opening of the second hood section 42 is larger than the diameter of the outer cylinder section 29; an air inlet and outlet groove 43 is formed in the middle of the first hood section 41 and the second hood section 42, and the air inlet and outlet groove 43 is communicated with the second support cylinder section 28;

[0036] Further, an annular support seat 44 is fixedly installed on the outer wall of the second hood section 42. A fourth bearing member 45 is installed at the bottom of the support seat 44. The support seat 44 is installed on the top of the outer cylinder section 29 through the fourth bearing member 45.

[0037] Specifically, the electrostatic adsorption mechanism 5 includes a positioning cylinder 51. A hollow groove 52 is formed inside the positioning cylinder 51. One end of the inner cavity of the hollow groove 52 is fixedly installed with a rope section positioning pipe 54. The electrostatic friction rope 55 is fixedly installed in the inner cavity of the hollow groove 52 through the rope section positioning pipe 54; positioning panels 53 are installed at both ends of the positioning cylinder 51 by bolts. The positioning cylinder 51 is clamped in the circular card slot of the prefabricated longitudinal groove 211 through the two positioning panels 53.

[0038] It can be understood that during actual use, first, the air inlet and outlet pipe 1 is connected to one end of the connecting pipe section 12 through the air pipe connecting bolt 21. The end of the air inlet and outlet pipe 1 far from the dust and debris inlet and outlet pipe mechanism 2 is connected to the air extraction or exhaust device. Immediately afterwards, the second support cylinder section 28 and the outer cylinder section 29 are connected to one end of the connecting pipe section 12 and the connecting pipe section 23. The air inlet and outlet of the air extraction or exhaust device can achieve the effect of removing the dust diffused in the air at the construction site;

[0039] During the process of air intake and exhaust, since the second support cylinder section 28 and the outer cylinder section 29 can rotate with the double-cylinder support seat 24 as the support point, when the air flow passes through the spiral fan blade 210, the second support cylinder section 28 will form a rotating state. When the second support cylinder section 28 rotates, the second support cylinder section 28 drives the gear block 33 to rotate through the first gear groove 34. When the gear block 33 rotates, it will drive the outer cylinder section 29 to reverse through the second gear groove 35, so that the second support cylinder section 28 and the outer cylinder section 29 form a forward and reverse rotation state. At this time, the static friction rope 55 will swing due to inertia. When the static friction rope 55 reciprocally rubs against the static friction ring 212, static electricity will be generated. In this way, fibrous materials can be adsorbed on the surface of the static friction rope 55 by static electricity, and floating dust materials can be directly washed away or directly sucked away. Because fibrous materials are lighter in mass, compared with dust, floating fibrous materials are more harmful to the human body on the one hand, and on the other hand, fibrous materials are very likely to block the dust extraction equipment. Therefore, through this solution, the state of static electricity adsorption and the effect of classified dust removal are achieved. Finally, by rubbing the outside of the outer cylinder section 29 by hand, the fibrous dust on the surface of the static friction rope 55 can fall off;

[0040] In addition, it should be noted that the structures of the first bearing part 25, the second bearing part 26, the third bearing part 31, and the fourth bearing part 45 are not detailed in the attached drawings of the specification in this solution. The bearings can be sealed bearings, pedestal bearings, etc. in the prior art, and are only used to express the specific installation positions of the bearing parts in the attached drawings of the specification.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
