[0004] When the above-mentioned technology is in use, although it achieves a certain degree of dust reduction effect by directly spraying water to the outside, this will also cause the relatively moist dust that falls directly to the ground to stick to the ground, making the ground muddy and slippery, thus affecting the construction of personnel. It cannot be used in environments where it is inconvenient to spray water, which leads to the low applicability of the above-mentioned technology when used. Therefore, in order to solve the above-mentioned technical problems, we proposed a green construction dust reduction device. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0027] Reference Figure 1-8 A green construction dust reduction device includes a collecting box 1, a discharge pipe 2 and a feed pipe 3 are respectively installed at the two ends of the upper side of the collecting box 1, a plurality of filter screens 4 are arranged inside the discharge pipe 2, a fan 5 is arranged at the end of the upper end of the feed pipe 3, one side of the tube body of the feed pipe 3 located between the fan 5 and the collecting box 1 is open and hinged with a conversion plate 6, spray nozzles 7 are installed on the tube bodies of the feed pipe 3 and the conversion plate 6, and each spray nozzle 7 is connected to an external water supply facility through a connecting pipe 8, and a restraint rope 9 is commonly sleeved between the upper ends of the connecting pipe 8. Example

[0028] Reference Figure 1-8 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0029] A protective frame 10 is installed on the outer side of the upper end of the feed pipe 3 by screws. The protective frame 10 is in the shape of a grid. The setting of the protective frame 10 is convenient for forming a protective grid at the end of the upper end of the feed pipe 3, that is, to prevent light and large-volume debris such as paper, plastic bags, and films from entering the feed pipe 3 and causing interference to the blades of the fan 5 inside the feed pipe 3; a protective cylinder 11 is installed on the inner side of the upper end of the feed pipe 3, and the motor in the fan 5 is installed inside the protective cylinder 11. The motor of the fan 5 is a waterproof motor, and the gap between the motor and the protective cylinder 11 is filled with coolant. The setting of the protective cylinder 11 and the coolant provides dust protection for the motor of the fan 5 while not causing too much adverse effect on the heat dissipation of the motor, thereby improving the stability of the components when the device is used; the tube body at the upper end of the feed pipe 3 is set to two sections, and the two sections of the tube body at the upper end of the feed pipe 3 are connected by a rotating connector 12, and the rotating connector 12 can be a bearing, so that it is convenient for personnel to adjust the dust suction direction of the device.

[0030] One end of the collecting box 1 is open and is equipped with a sealing door 13. An observation window 14 is provided in the middle of the sealing door 13. The setting of the sealing door 13 is convenient for sealing and finally cleaning the dust and water inside the collecting box 1; the filtering precisions of the various filter screens 4 inside the discharge pipe 2 are different, and the filtering precision of the bottom filter screen 4 is the lowest. Since the filtering precisions of the various filter screens 4 are different, the device can have different dust reduction effects; the restraining rope 9 is elastic, and rings 15 are provided at both ends of the restraining rope 9. The setting of the ring 15 makes it convenient for personnel to connect the two ends of the restraining rope 9 to the upper end of the connecting pipe 8.

[0031] Principle and advantages of use: During the use of the utility model, an external water pump or water supply facility such as tap water supplies water to the spray nozzle 7 through the connecting pipe 8, so that water mist can be sprayed out from the spray nozzle 7. Then, during use, if the external environment can directly spray water mist, the personnel first remove the restraining rope 9, and then flip the conversion plate 6 outward, and finally fix the position of the conversion plate 6 through the restraining rope 9, that is, under the action of the restraining rope 9, when the restraining rope 9 is away from the hinge, the conversion plate 6 is restrained and fixed at the feed pipe 3, at this time, the conversion plate 6 and the feed pipe 3 form a complete pipe body, when the restraining rope 9 is close to the hinge, the conversion plate 6 is restricted by the restraining rope 9 and flipped outward, that is, at this time, the conversion plate 6 is in an outwardly opened state, at this time, the feed pipe 3 and the spray nozzle 7 at the conversion plate 6 can directly spray water mist to the outside, so that the water mist combines with the dust in the air, and finally achieves the dust reduction effect.

[0032] In the above process, if the external environment is restricted, that is, it is impossible to spray water mist directly to the outside, the conversion plate 6 is combined with the feed pipe 3 through the restraining rope 9, and then the fan 5 is started. The fan 5 generates a negative pressure so that the turbid air from the outside is sucked in from the upper end of the feed pipe 3 and sprayed into the collection box 1, and finally discharged from the discharge pipe 2. In this process, when the dust flows through the spray nozzle 7 with the air, the dust combines with the water mist, thereby achieving a better dust reduction effect. Subsequently, the air that has been dust-reduced by the water mist is filtered again when it flows through the filter net 4, thereby effectively reducing the dust from the turbid air from the outside through the multi-stage filtering component, and the water mist will not be directly sprayed onto the ground outside.

[0033] In the above process, if the external environment restricts the air humidity, the connecting pipe 8 is closed at this time, so that the spray nozzle 7 cannot spray water mist, and the turbid air is subjected to dust reduction treatment through the filter 4; in summary, during the use of this solution, through the setting of the conversion plate 6, the device can conveniently adjust the dust reduction measures according to different usage scenarios, thereby having a multi-stage dust reduction effect and multiple dust reduction methods, thereby solving the defect of poor adaptability when using the traditional solution.

[0034] It should be further explained that the provision of the protection frame 10 facilitates the formation of a protection grille at the end of the upper end of the feed pipe 3, thereby preventing light and large-volume debris such as paper, plastic bags, and films from entering the feed pipe 3 and causing interference with the blades of the fan 5 inside the feed pipe 3; the provision of the protection tube 11 and the coolant provides dust protection for the motor of the fan 5 while not causing too much adverse effect on the heat dissipation of the motor, thereby improving the stability of the components when the device is in use; the rotating connector 12 can be a bearing, thereby facilitating personnel to adjust the dust suction direction of the device; the provision of the sealing door 13 facilitates the sealing and final cleaning of the dust and water inside the collection box 1; the provision of the ring 15 facilitates personnel to connect the two ends of the restraint rope 9 to the upper end of the connecting pipe 8.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
