[0023] like Figures 1 to 6 As shown, the utility model relates to a spray device for building construction, comprising a fixing frame 1, a clamp 2 fixed to an external building steel frame is installed at one end of the fixing frame 1, a hollow rod 3 is connected to the other end of the fixing frame 1, a spray inner cover 4 is fixed to the outer periphery of one end of the hollow rod 3, a spray exhaust fan 5 is rotatably connected to the end of the hollow rod 3, the spray inner cover 4 is a suction opening close to the dust-raising side, an air outlet valve is provided on the other side of the spray inner cover 4, a mud discharge port is provided at the bottom of the spray inner cover 4, a fan blade portion of the spray exhaust fan 5 is designed to fit the inner side of the spray inner cover 4, a spray head 6 fixed to the spray inner cover 4 is provided on one side of the spray exhaust fan 5, a spray cylinder 7 is provided inside the spray head 6, the spray cylinder 7 is connected to an external water supply unit, and the external water supply unit can be a water tank with a liquid extraction pipe.

[0024] The working principle is to arrange it according to the area where dust is generated more frequently, use multiple devices in conjunction with the clamp 2 to fix it on the steel frame of the building steel structure, and then connect the mud discharge port to the mud guide pipe. A collection box with a filter plate can be set below according to needs. When used in this way, a high suction force will be generated through the operation of the spray exhaust fan 5, and then the atomized spray of the spray cylinder 7 and the spray head 6 can react with the deposition reaction on the sucked-in dust, so that it will settle to the lower mud discharge port, thereby achieving efficient dust reduction.

[0025] The spraying liquid can be selected according to the situation. The most commonly used one is water. When water is sprayed on the dust, the dust particles will absorb water molecules, and the particles will gather together due to the action of water molecules. At the same time, because water increases the weight of the dust particles, they are easier to settle under the action of gravity. In addition, calcium chloride, calcium chloride (CaCl2) and other salt substances can be selected to improve the effect. Principle: Calcium chloride is a highly hygroscopic salt. When calcium chloride particles are exposed to the air, they absorb moisture in the air and form a deliquescence phenomenon. At the construction site, calcium chloride can absorb moisture in the air and increase the humidity of the surrounding environment. In a high humidity environment, construction dust particles are easy to absorb moisture, thereby increasing weight and accelerating sedimentation. In addition, calcium chloride solution can react chemically with some components in the dust (such as certain metal oxides) to generate more insoluble substances and promote dust deposition.

[0026] Since the dust reduction effect is improved by combining the suction force of the fan and the spraying during the installation, and multiple arrays are arranged, if normal operating equipment or structures are used, the operating cost will be greatly increased and the practicality will be affected. In view of this, a spray liquid extraction structure 8 is arranged inside the spray cylinder 7, and the spray liquid extraction structure 8 includes a liquid extraction shell 801, and a one-way inlet valve 802 and a plurality of one-way outflow valves 803 are connected to the outer periphery of the liquid extraction shell 801. The one-way inlet valve 802 is connected to an external water supply unit. A cylindrical cam 804 is provided in the center of the liquid extraction shell 801, and an elliptical reciprocating plate 805 is provided on the outer periphery of the cylindrical cam 804. Due to the non-circular design of the reciprocating plate 805, its self-rotation is avoided. The reciprocating plate 805 fits the inside of the liquid extraction shell 801. A circular cavity is provided at the center of the hollow rod 3, and a limiting column 806 is integrally formed on the circular cavity. The contact parts of the reciprocating plate 805 and the cylindrical cam 804 are bonded with a rubber layer to strengthen the seal. The cylindrical cam 804 is provided with a first-connected reciprocating curved groove 807, and a spray driving structure 9 is provided at one end of the hollow rod 3 away from the spray pumping structure 8. The spray driving structure 9 includes a driving shell 901, one end of the driving shell 901 is fixed to the hollow rod 3, the interior of the driving shell 901 is a circular cavity, the center of the driving shell 901 is rotatably connected to the center rod 902, and the periphery of the center rod 902 is connected to a plurality of blades 903. The top and bottom of the driving shell 901 are respectively provided with an air inlet 904 and an air outlet 905, and the air inlet 904 and the air outlet 905 are connected to an external air supply unit.

[0027] It is worth mentioning that the center rod 902 passes through the hollow rod 3 and the spray cylinder 7 and is fixedly connected to the center of the cylindrical cam 804, and the outer periphery of the center rod 902 is connected to the center of the spray exhaust fan 5, that is, the operation of the center rod 902 can drive the two movements to run synchronously, and an air pump station can be arranged on the construction site to cooperate with multi-way pipes to connect with several devices, thereby further reducing the operating cost.

[0028] Working principle: during operation, the external air supply unit delivers gas, and the gas is input from the air inlet 904, which drives the blades 903 to rotate, so that the center rod 902 rotates, and the spray exhaust fan 5 rotates to suck the external dust. At the same time, the rotation of the center rod 902 drives the cylindrical cam 804 to rotate, so that the reciprocating curved groove 807 rotates, and the reciprocating plate 805 moves back and forth. Combined with the design of the one-way inlet valve 802 and multiple one-way outlet valves 803, water enters from the one-way inlet valve 802, and then sprays out from the multiple one-way outlet valves 803, and then sprays out through the spray cylinder 7 and the spray head 6. Therefore, through the operation of a center rod 902, its suction and spraying are driven, and one pump station can drive multiple devices to operate at the same time, greatly reducing the operating cost.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
