Description

Technical Field

[0001] This invention belongs to the field of spray head technology and relates to a spray head with anti-clogging function. Background Technology

[0002] In mining operations, spraying operations are required to control the underground environment and prevent explosions such as gas and coal dust that frequently occur in mines. During the spraying process, water is atomized through an external water supply system to control and reduce dust.

[0003] A spray head is a common spraying device widely used in agriculture, horticulture, firefighting, and industry. The basic principle of a spray head is to utilize the pressure and velocity of water flow to atomize the water into fine droplets through a nozzle, forming a uniform spray. The spray effect of a spray head mainly depends on the structure and shape of the nozzle; different nozzles can produce different spray angles, ranges, and densities.

[0004] However, spray heads often encounter nozzle clogging during use, leading to reduced spray performance or even complete malfunction. The main cause of nozzle clogging is the presence of particulate matter in the water flow, such as mud, sand, and pebbles. These particles enter the nozzle with the water flow and easily cause blockage due to the small outlet size. To address this issue, current spray heads typically incorporate a filter or screen at the inlet to block particulate matter in the water flow. However, this method also has drawbacks. The filter or screen itself is prone to clogging by particulate matter, requiring regular cleaning or replacement, increasing operating costs and maintenance complexity. Furthermore, the filter or screen can reduce water pressure and velocity, affecting spray performance. Additionally, the addition of a filter or screen increases the size and weight of the spray head, making installation and portability inconvenient. Summary of the Invention

[0005] In view of this, the present invention addresses the shortcomings of the prior art by providing a spray head with anti-clogging function.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A spray head with anti-clogging function includes a spray head housing, a nozzle, a flow divider ring, a swirling core, and an annular spiral blade; the nozzle, swirling core, and flow divider ring are sequentially disposed inside the spray head housing; the annular spiral blade is rotatably disposed inside the flow divider ring and rotates under the drive of water flow to crush particulate dust in the water flow;

[0008] One end of the diverting ring is tightly attached to the vortex core, and the other end is connected to the water inlet of the nozzle housing. The diverting ring is provided with several diverting grooves. A buffer cavity is formed between the outer wall of the vortex core and the nozzle housing. The diverting grooves are connected to the buffer cavity, and the inner cavity of the vortex core is connected to the nozzle. The vortex core is provided with several vortex holes. One end of each vortex hole is connected to the buffer cavity, and the other end is connected to the inner cavity of the vortex core. The water flows sequentially through the diverting groove, the buffer cavity, the vortex holes, and the inner cavity of the vortex core before being atomized and sprayed out from the nozzle.

[0009] Furthermore, the annular spiral blade includes a connecting rod and multiple annular blades. The annular blades are rotatably mounted on one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the end face of the vortex core. The annular blades are hollow annular structures in a spiral shape. The sidewalls of the annular blades act as cutting edges, impacting, cutting, and crushing dust particles. Compared with conventional spiral blades, the annular structure can form more cutting edges within the same area, resulting in higher crushing efficiency and better crushing effect.

[0010] Furthermore, the swirling holes are distributed in a spiral radial pattern on the swirling core, and the outlet end of any one swirling hole is not opposite to the outlet end of another swirling hole.

[0011] Furthermore, the flow divider ring is connected to the nozzle housing by a thread; the flow divider ring is fitted to the swirl core by a conical surface, and the flow divider grooves are arranged in a circular array on the conical surface.

[0012] Furthermore, the swirling core is pressed against the nozzle end face, and the outer wall of the nozzle is bonded to the nozzle housing via a conical surface; the swirling core and the nozzle are pressed and fixed by the threaded connection between the flow divider ring and the nozzle housing.

[0013] Furthermore, the annular blade is located above the inlet end of the diversion channel.

[0014] Furthermore, a connector is provided at the end of the nozzle housing away from the nozzle, which is connected to the water supply pipe.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The spray head of the present invention utilizes annular spiral blades that rotate under the drive of water flow to crush particulate dust in the water flow, thereby preventing particulate dust from clogging the nozzle and ensuring the spraying effect.

[0017] 2. The spray head of the present invention utilizes the swirling holes on the swirling core to generate a swirling effect, so that the water flow forms a stable vortex in front of the nozzle, thereby improving the uniformity and stability of the spray.

[0018] 3. The spray head of the present invention has a simple structure, low cost, and is easy to manufacture and use. It does not require additional power or control devices and has a self-cleaning function, which reduces the difficulty of maintenance.
