Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an environmental dust removal device for building engineering construction. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls and foundations, as well as internal spaces that can meet people's production, living, learning and public activities. It is well known that a large amount of dust will be generated during the construction of construction projects. These dusts have caused serious pollution to the environment, so dust removal devices are an indispensable device during the construction of construction projects. The current construction dust removal devices generally use atomizers in combination with hair dryers for spray dust removal, but this method easily blows the dust in the air and spreads it. Part of the dust has already floated away, and this part of the dust is no longer within the dust removal range of the atomizer, so the dust cannot be gathered and removed, which reduces the dust removal effect and efficiency.

[0003] After searching, it is found that the existing Chinese patent publication number: CN218221663U is a dust removal device for construction projects, including a main base, a support frame and an outer shell, one side of the top of the main base is fixedly connected with a rotating groove, both sides of the inside of the rotating groove are installed with lateral angle adjustment structures, the lateral angle adjustment structure includes a threaded groove, a threaded rod, a rubber pad and a ball, a support frame is installed on the top of the rotating groove, a water tank is provided on the other side of the top of the main base, and a fan is installed on the other side of the inside of the outer shell.

[0004] The cited patent document also has the same problem. The atomizer cannon is used in conjunction with a hair dryer to spray and remove dust, but this method easily spreads the dust in the air. Part of the dust has already floated away, and this part of the dust is no longer within the dust removal range of the atomizer cannon. The dust cannot be gathered and removed, which reduces the dust removal effect and efficiency. Utility Model Content

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0031] The preferred embodiment of the utility model is a dust removal device for construction engineering environment. Figure 1-Figure 4 As shown, it includes a construction dust removal cart 1 and a water tank 3 installed inside the construction dust removal cart 1, moving wheels 2 are symmetrically arranged on both sides of the bottom surface of the construction dust removal cart 1, and a water pump 8 is installed on the top of the water tank 3. The input end of the water pump 8 extends to the inner cavity of the water tank 3 through a water pipe fitting, so that the water in the inner cavity of the water tank 3 can be extracted under the action of the water pump 8, and then output through the output pipe of the water pump 8.

[0032] In this embodiment, an inverted U-shaped support frame 4 is installed on the top surface of the construction dust removal cart 1, and a negative pressure dust removal fan 5 for providing negative pressure to attract dust is rotatably installed on the top surface of the U-shaped support frame 4. A support disc 20 is provided in the middle of the top surface of the U-shaped support frame 4, and a connecting disc 9 is provided on the bottom surface of the negative pressure dust removal fan 5. A rotating motor 22 is embedded in the middle of the top surface of the supporting disc 20, and the output shaft of the rotating motor 22 is connected to the connecting disc 9.

[0033] Specifically, a motor slot 21 for installing the rotating motor 22 is opened in the middle of the top surface of the supporting disc 20, and a key block is provided on the circumferential side of the output shaft of the rotating motor 22, and a mounting hole that is installed in accordance with the output shaft and the key block of the rotating motor 22 is opened on the bottom surface of the connecting disc 9, so that the rotating motor 22 can drive the connecting disc 9 to rotate, thereby enabling the connecting disc 9 to drive the negative pressure dust removal fan 5 to swing and rotate on the U-shaped support frame 4, and at the same time, the rotation range of each swinging rotation is less than 360°, which prevents entanglement of the pipe fittings, and at the same time can expand the negative pressure suction range of the negative pressure dust removal fan 5, thereby improving the dust removal range and efficiency.

[0034] In this embodiment, the top surface of the negative pressure dust removal fan 5 is provided with a linear motion module, and a dust removal spray head 7 is arranged on the linear motion output end of the linear motion module. The linear motion module includes a linear motion housing 6 and a screw member (not shown in the figure) rotatably installed in the inner cavity of the linear motion housing 6, and a movable support 11 which is horizontally penetrated by the screw member and slides on the top surface of the linear motion housing 6. A servo motor 14 is installed on the outer wall of one end of the linear motion housing 6, and the output shaft of the servo motor 14 is fixedly connected to the screw member. A mounting boss 19 is integrally formed on the top surface of the negative pressure dust removal fan 5. The linear motion housing 6 is fixedly installed on the top surface of the mounting boss 19 by bolts. A support plate 12 is welded on the top surface of the movable support 11, and the dust removal spray head 7 is fixedly installed on the upper part of the support plate 12. The output end of the water pump 8 is connected to the dust removal spray head 7 through a delivery hose 13.

[0035] Specifically, when the negative pressure dust removal fan 5 is swinging to adjust the angle, the servo motor 14 performs forward and reverse operation to drive the screw to rotate in the inner cavity of the linear movable shell 6, so that the screw drives the movable support 11 to move back and forth in a straight line, thereby causing the movable support 11 to drive the dust removal spray head 7 to move forward and backward in synchronization with the swing adjustment of the negative pressure dust removal fan 5. Therefore, the cooperation between the two can not only expand the dust removal spray range and meet the attraction of dust at different positions, but also reduce the dust caused by the negative pressure attraction force through the forward and backward movement of the dust removal spray head 7, thereby improving the dust removal effect and efficiency.

[0036] In this embodiment, the back of the negative pressure dust removal fan 5 has a filter assembly that can filter dust carrying water droplets by suction under negative pressure. The back of the negative pressure dust removal fan 5 is threadedly connected to a detachable end cover 10. The end of the negative pressure dust removal fan 5 has an external threaded tube 15, and the inner wall of the detachable end cover 10 has an internal threaded path 18 that is threadably matched with the external threaded tube 15. The filter assembly includes a filter mesh 16 installed in the detachable end cover 10, and the outer end wall of the detachable end cover 10 has a limit ring 17 for limiting and blocking the filter mesh 16.

[0037] Specifically, after the negative pressure dust removal fan 5 has been working for a period of time, dust will adhere to the filter mesh 16 due to the attraction of negative pressure. Therefore, the filter mesh 16 needs to be disassembled and cleaned in time. When disassembling the filter mesh 16, it is only necessary to loosen the detachable end cover 10 to separate the detachable end cover 10 and the negative pressure dust removal fan 5, and take the filter mesh 16 out of the detachable end cover 10 for water flushing or brush cleaning.

[0038] Working principle:

[0039] The environmental dust removal device for construction engineering is moved to the construction site, and the water pump 8, the negative pressure dust removal fan 5, the rotating motor 22 and the servo motor 14 are turned on. The rotating motor 22 can drive the connecting disc 9 to rotate, so that the connecting disc 9 drives the negative pressure dust removal fan 5 to swing and rotate on the U-shaped support frame 4. The water output by the water pump 8 is transported from the delivery hose 13 to the dust removal spray head 7, and the dust removal spray head 7 sprays to reduce dust. When the negative pressure dust removal fan 5 is in the process of swinging to adjust the angle, the servo motor 14 performs forward and reverse operation to drive the screw member to rotate in the inner cavity of the linear movable housing 6, so that the screw member drives the movable support 11 to move back and forth in a straight line, so that the movable support 11 drives the dust removal spray head 7 to move forward and backward and synchronize with the swing adjustment of the negative pressure dust removal fan 5, and the dust caused by the negative pressure attraction is reduced by the forward and backward movement of the dust removal spray head 7.

[0040] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
