Description

Technical Field

[0001] This utility model belongs to the field of spraying devices, specifically relating to an anti-drip spray head. Background Technology

[0002] Currently, dust suppressant spraying devices are used on coal transportation lines in my country to reduce coal dust pollution along the route. Existing swing-arm type dust suppressant spraying devices typically have horizontally arranged spray pipes with nozzles installed at the bottom of the pipes. After spraying stops, liquid continues to flow out through the nozzles, causing dripping. Therefore, an anti-drip nozzle is proposed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide an anti-drip nozzle to solve the problem that existing dust suppressant spraying devices continue to drip after spraying has stopped.

[0004] The technical solution of this utility model is: an anti-drip spray head, including a nozzle and a spray core, and also including an inner cylinder, the inner cylinder being connected to the upper end of the nozzle, the inner cylinder being installed at the bottom of the spray pipe, and the upper end of the inner cylinder extending into the spray pipe.

[0005] As a further improvement of this utility model, the nozzle and the inner cylinder are connected by threads.

[0006] As a further improvement of this utility model, the lower end of the spray core is provided with a conical surface.

[0007] As a further improvement of this utility model, it also includes an adjusting screw and an adjusting nut. The adjusting screw is connected to the nozzle core, and the adjusting nut is connected to the nozzle through a connecting block. The adjusting screw and the adjusting nut are connected by threads.

[0008] The beneficial effects of this utility model are: 1. This utility model has an inner cylinder at the upper end of the nozzle, with the upper end of the inner cylinder extending into the spray pipe. When spraying, the liquid level in the spray pipe is higher than the upper end of the inner cylinder, and the liquid enters the nozzle from the inner cylinder, allowing the nozzle to spray normally. When spraying stops, the liquid level in the spray pipe is lower than the upper end of the inner cylinder, and the liquid in the spray pipe will not enter the inner cylinder, thereby reducing dripping.

[0009] 2. In this utility model, the spray core is installed inside the nozzle by adjusting the lead screw and adjusting nut. The vertical position of the spray core can be adjusted by adjusting the thread between the lead screw and adjusting nut, thereby adjusting the gap between the conical surface of the spray core and the inner wall of the nozzle, and thus adjusting the spray volume.

[0012] The present invention will now be described in detail with reference to the accompanying drawings.

[0013] Example 1 like Figure 1-3 As shown, an anti-drip spray head includes a nozzle 1 and a spray core 3, and also includes an inner cylinder 2. The inner cylinder 2 is connected to the upper end of the nozzle 1 and is installed at the bottom of a spray pipe 6. The upper end of the inner cylinder 2 extends into the spray pipe 6. In this embodiment, the upper end of the inner cylinder 2 extends into the spray pipe 6 by at least half a diameter.

[0014] Nozzle 1 is connected to inner cylinder 2 by threads.

[0015] The lower end of the spray core 3 is provided with a conical surface.

[0016] It also includes an adjusting screw 5 and an adjusting nut 4. The adjusting screw 5 is connected to the spray core 3, and the adjusting nut 4 is connected to the nozzle 1 through three connecting blocks 7. The adjusting screw 5 and the adjusting nut 4 are connected by threads.

[0017] During spraying, the liquid level in the spray pipe 6 is higher than the upper end of the inner cylinder 2, and the liquid enters the nozzle 1 from the inner cylinder 2, and the nozzle sprays normally; when spraying stops, the liquid level in the spray pipe 6 is lower than the upper end of the inner cylinder 2, and the liquid in the spray pipe 6 will not enter the inner cylinder 2, thereby reducing dripping.

[0018] Tightening the adjusting screw 5 allows adjustment of the up-down position of the spray core 3 via the thread between the adjusting screw 5 and the adjusting nut 4, thereby adjusting the gap between the conical surface of the spray core 3 and the inner wall of the nozzle 1, and thus adjusting the spray volume.

[0019] The nozzle 1 is connected to the inner cylinder 2 by a thread, which makes it easy to disassemble and assemble, simple to operate, easy to maintain, and highly practical.
