Description

Technical Field

[0001] The utility model belongs to the technical field of liquid atomization equipment, and relates to an atomizing nozzle, in particular to a single-fluid solid cone atomizing nozzle. Background Technique

[0002] The main dust prevention measure in coal mines in China is spray dust removal. As the most basic component of spray dust removal, the atomization ability (spray pattern and droplet size) of the nozzle directly determines the effect of spray dust removal.

[0003] An atomizing nozzle is a device that can atomize and eject a liquid so that it can be evenly suspended in the air. Its working principle is that through internal pressure, the internal liquid is squeezed into the nozzle. There is an iron sheet placed inside the nozzle. The high-speed flowing liquid impacts on the iron sheet, and after rebounding, atomized particles with a diameter of about 15 - 60 microns are formed and ejected through the nozzle outlet. At present, the spray pattern formed by the existing single-fluid atomizing nozzles on the market is a hollow cone, that is, the atomized particles ejected by the atomizing nozzle are in a conical circular ring shape, and there are no atomized particles ejected in the central part, resulting in a poor humidifying spray effect.

[0004] Therefore, for those skilled in the art, it is still necessary to develop a single-fluid solid cone atomizing nozzle with good humidifying and dust reduction effects. Summary of the Invention

[0005] The purpose of the utility model is to address the above problems existing in the prior art, and propose a single-fluid solid cone atomizing nozzle, which has the characteristics of good humidifying and dust reduction effects and solves the above problems.

One end of the body is provided with an insert. One side of the insert is provided with a nozzle gland. An outlet hole is opened inside the insert. An inlet hole is opened inside the nozzle gland. The nozzle body, the insert and the nozzle gland form a cavity, and the cavity is communicated with the inlet hole and the outlet hole. A locking member is provided on the other side of the nozzle gland. The insert and the nozzle gland are pressed tightly inside the nozzle body by the locking member.

[0007] By adopting the above technical solutions, by providing an insert and opening an outlet hole inside the insert, after the liquid enters the nozzle body, it passes through the cavity and then enters the inlet hole of the nozzle gland, and then enters the inner cavity of the insert and moves along its length direction to the outlet hole and is ejected, realizing the solid injection of liquid atomization and improving the humidifying and dust removal effects.

[0008] In the above-mentioned single-fluid solid-cone atomizing nozzle, a connecting member is provided on the other side of the locking member, and a filter screen is sleeved on the outer wall of the connecting member.

[0009] By adopting the above technical solution, the filter screen can quickly filter the water entering the nozzle body.

The diameters on both sides of the frustum of the cone match the diameters of the first hole and the second hole respectively, and the diameter of the first hole is larger than the diameter of the second hole.

[0013] By adopting the above technical solution, the atomized liquid droplets can be ejected in a solid-cone shape, improving the effect of humidification and dust removal.

The diameters on both sides of the frustum of the cone match the diameters of the first through hole and the second through hole respectively, and the diameter of the first through hole is smaller than the diameter of the second through hole.

[0015] By adopting the above technical solution, under the action of pressure, the water entering the nozzle gland from the cavity sprays towards the insert, so that the water entering the inner cavity of the insert moves at a high speed and can be ejected from the water outlet hole of the insert.

[0016] In the above-mentioned single-fluid solid-cone atomizing nozzle, a round hole is opened on the locking member.

[0017] By adopting the above technical solution, a round hole is opened on the locking member, and the water filtered by the filter screen enters the cavity of the nozzle body through the hole.

[0018] In the above-mentioned single-fluid solid-cone atomizing nozzle, the filter screen is made of stainless steel.
