Technical Field

[0001] The utility model belongs to the technical field of spray devices, and in particular relates to an angle-adjustable spray device. Background Art

[0002] Dust refers to solid particles suspended in the air. Dust pollution directly threatens people's lives. Long-term exposure to dust pollution can cause a variety of cardiovascular and respiratory diseases. Excessive dust can easily breed bacteria and viruses, and is also extremely harmful to skin health.

[0003] The density of dust suspended in the production workshop of the factory is much denser than that of outdoor air. Therefore, it is necessary to use a water mist dust removal device in the production workshop to reduce dust. The existing water mist dust removal device absorbs dust in the air by spraying and makes it fall to the ground with the water mist. However, the nozzle of the existing water mist dust removal device is usually fixed and the direction of the nozzle cannot be changed. The dust removal effect is limited and cannot meet the use requirements of different occasions. Utility Model Content

For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0024] Example 1

[0025] like Figure 1-3 As shown, this embodiment provides an angle-adjustable spray device, including a mounting member 1, a rotating member 3, a mounting seat 4, a rotating shaft 5, and a fixed shaft 2;

[0026] The mounting member 1 is fixed on a wall or other mounting position, the mounting member 1 is fixed to the rotating shaft 5, the rotating member 3 is penetrated by a rotating hole, the rotating shaft 5 is inserted in the rotating hole, so that the rotating member 3 can rotate around the rotating shaft 5, the rotating member 3 is penetrated by a first positioning hole, the mounting member 1 is penetrated by a plurality of second positioning holes, and the plurality of second positioning holes are evenly spaced along the circumference of the rotating shaft 5, the fixed shaft 2 is simultaneously inserted in the first positioning hole and one of the second positioning holes, so that the mounting member 1 and the rotating member 3 remain relatively fixed, and the rotating member 3 cannot rotate around the rotating shaft 5 at this time, the mounting seat 4 is fixed to the rotating member 3, and the mounting seat 4 is used to install the spray unit 6, and the spray unit 6 can be a rod-type spray unit or a box-type spray unit.

[0027] Based on the above structure, after the fixed shaft 2 is removed, the rotating member 3 can rotate around the rotating shaft 5, which can drive the mounting seat 4 to rotate, and then drive the spray unit 6 to rotate. After adjusting to a suitable position, the fixed shaft 2 is inserted into the first positioning hole and the corresponding second positioning hole again to fix the rotating member 3. In this way, during use, the spray angle of the spray unit 6 can be adjusted at any time to target the dust-generating point, meet the dust suppression needs of various occasions, such as gates, silos, and scrap steel rooms, and achieve a good spray dust removal effect.

[0028] In this embodiment, the mounting base 4 may include an outer cylinder 401 and two locking bolts 402. A spray hole 403 is opened on the side wall of one side of the outer cylinder 401, and the spray hole 403 extends from one side to the other side. That is, the cross-section of the outer cylinder 401 is a C-shaped structure.

[0029] Two through holes are provided on the side wall on the other side of the outer cylinder 401, and two locking rings 404 with internal threads are fixed on the side wall of the outer cylinder 401, the two locking rings 404 are coaxial with the two through holes, the two locking bolts 402 are screwed with the two locking rings 404, and the two locking bolts 402 are coaxial with the two through holes, the inner ends of the locking bolts 402 pass through the coaxial through holes and extend to the inside of the outer cylinder 401, and the inner ends of the two locking bolts 402 and the outer cylinder 401 jointly clamp and fix the spray unit 6.

[0030] For example, when the spray unit 6 is a rod-type spray unit, the rod-type spray unit is slid into the opening at one end of the outer cylinder 401. After reaching the designed position, the locking bolt 402 is rotated so that the inner end of the locking bolt 402 gradually approaches the rod-type spray unit until the inner end of the locking bolt 402 abuts against one side of the rod-type spray unit. At this time, the other side of the rod-type spray unit abuts against the inner wall of the outer cylinder 401. Figure 1 As shown, the inner ends of the two locking bolts 402 are respectively abutted against the air pipe and water pipe of the rod-type spray unit, and the bottom of the rod-type spray unit is abutted against the inner bottom of the outer cylinder 401, and the nozzle of the rod-type spray unit is exposed from the spray hole 403, so that the rod-type spray unit can be firmly fixed.

[0031] In this embodiment, the mounting member 1 and the mounting seat 4 are both sheet metal parts. The mounting member 1 can be an L-shaped structure. One side of the L-shaped structure is fixed to the rotating shaft 5, and the other side of the L-shaped structure is penetrated with a screw hole, through which the mounting seat 4 can be fixed to a wall or other location by bolts. The bends of the mounting seat 4 are all chamfered to an obtuse angle. The mounting seat 4 is welded and fixed to the rotating member 3, and the welding fixation method is more secure.
