Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction spray equipment, in particular to dust reduction spray equipment for a garbage landfill. Background Art

[0002] In the process of handling garbage in landfills, a large amount of dust is generated due to the decomposition, transportation and operation of garbage. This dust not only pollutes the air, but may also be blown to surrounding areas by the wind, posing a threat to the living environment and health of residents. At present, dust reduction spray equipment is generally used to treat dust. It can moisten and settle dust particles in the air by spraying water mist, effectively reducing dust concentration and improving air quality.

[0003] The patent with the current announcement number CN219424010U discloses a spray-type dust reduction device, which includes a base, a rotating device, a supporting structure and a spray device. The rotating device is installed inside the base, the supporting structure is installed at the top of the rotating device, and the spray device is installed in the middle of the supporting structure. The rotating device includes a transmission unit, a rotation unit and a limit unit. The transmission unit, the rotation unit and the transmission unit are installed in sequence. The transmission unit includes a motor, a transmission shaft, and a threaded sleeve. The motor is fixedly installed on the bottom surface of the inner wall of the base. The spray-type dust reduction device is equipped with a threaded sleeve, a gear, a transmission block, a groove and a rotating rod. When the device is used, the threaded sleeve drives the gear to rotate so that the transmission block performs regular reciprocating motion in the groove, thereby rotating the rotating rod, thereby achieving the effect of rotating the device.

[0004] However, the above technology still has the following problems:

[0005] After the dust suppression spray equipment is used, water will remain in its spray head and water pipe. In the cold winter environment, it is easy for the water remaining in the spray head and water pipe to freeze into ice, which will cause the spray head or water pipe to be blocked, making it take a long time to thaw when work is needed, affecting work efficiency.

[0018] 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.

[0019] See also Figures 1 to 3 A dust suppression spray device for a landfill includes a fog cannon main body 1, which includes a spray barrel and a base. A rotating component 2 is fixedly connected to the upper surface of the spray barrel, a protective component 3 is fixedly connected to the rotating component 2, a limiting component 4 is fixedly connected to the surface of the spray barrel, and a water supply pipe 5 is connected to the bottom of the spray barrel.

[0020] The dust suppression spray device for landfill in the utility model is similar in structure to the existing dust suppression spray device, such as the spray dust suppression device disclosed in the publication number CN219424010U. The main improvement of the utility model is that the spray head of the dust suppression spray device is protected by the protective component 3 to prevent the residual water in the spray head from being frozen due to the low temperature in winter, causing the spray head to be blocked, thereby affecting the spray effect. Figures 1 to 3 As shown, the dust reduction spray equipment for landfill in the utility model can be used in winter when the dust reduction spray equipment is not needed. The tightening bolt 404 on the limit assembly 4 is removed, and the protective assembly 3 is rotated around the rotating shaft 203. The protective cover 301 covers the front end of the spray barrel, and the tightening bolt 404 is passed through the circular hole 305 and threadedly connected to the third fixed block 402 to fix the protective assembly 3 to protect the spray head. At the same time, in the case that the spray head is frozen, the heating plate 302 connected to the power supply in the fog cannon body 1 is started to heat the spray head so that the spray head is thawed to prevent the spray effect from being affected during the spray operation.

[0021] like Figure 1 As shown, the surface of the water supply pipe 5 is covered with a first thermal insulation layer.

[0022] Specifically, the first insulation layer is a plastic foam insulation material to prevent the water supply pipe 5 from being frozen due to the low temperature in winter, thereby affecting the spraying work.

[0023] like Figure 3 As shown, the rotating assembly 2 includes a first fixed block 201 fixed above the air outlet of the spray barrel, a groove 202 is provided on the surface of the first fixed block 201, a rotating shaft 203 is rotatably connected in the groove 202, and an L-shaped support rod 204 is fixedly connected to the rotating shaft 203.

[0024] Specifically, when the protection component 3 is used, the protection component 3 is rotated so that the protection component 3 rotates around the rotating shaft 203 along with the L-shaped support rod 204 until the protection component 3 rotates to the front end of the spray barrel to cover the spray head. When not in use, it can be rotated in the opposite direction.

[0025] like Figure 2 As shown, the protection component 3 includes a protection cover 301, a heating plate 302 is fixedly connected inside the protection cover 301, a second insulation layer 303 is provided on the outer surface of the protection cover 301, a baffle 304 is fixedly connected to the front end of the protection cover 301, and a circular hole 305 is opened on the baffle 304.

[0026] Specifically, the protective cover 301 covers the spray head, and the second insulation layer 303 prevents the residual water in the spray head from being frozen. For the frozen spray head, the heating plate 302 can also be started to heat and thaw it to ensure the circulation of the spray head, thereby ensuring the spray efficiency of the dust reduction spray equipment.

[0027] like Figure 3 As shown, the limiting assembly 4 includes a second fixing block 401 fixed below the baffle 304, and a third fixing block 402 is fixedly connected to the lower surface of the spray barrel. The surfaces of the second fixing block 401 and the third fixing block 402 are both provided with threaded holes 403 corresponding to the circular holes 305, and the threaded holes 403 are internally threadedly connected with tightening bolts 404.

[0028] Specifically, before the dust reduction spray equipment works, the protective component 3 is rotated around the rotating shaft 203 to the second fixed block 401, the tightening bolt 404 is placed in the circular hole 305, and the tightening bolt 404 is rotated to turn the tightening bolt 404 into the threaded hole 403, so that the protective component 3 is fixed above the spray barrel, which does not affect the normal spraying operation of the dust reduction spray equipment. When the dust reduction spray equipment is no longer needed, the tightening bolt 404 is promptly released, and the protective component 3 is rotated to the front end of the spray barrel to fit with the third fixed block 402, and the removed tightening bolt 404 is reconnected to the threaded hole 403 in the third fixed block 402, so that the protective component 3 covers the spray head, thereby preventing the spray head from being frozen.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
