Abstract
The invention discloses an efficient and abrasion-resisting nozzle with a swirl flow core. Aiming at the difficult problems that a prior nozzle used for spraying and aspirating underground a coal mine is not ideal in atomization effect and is prone to being abraded and blocked, the efficient and abrasion-resisting nozzle with the swirl flow core comprises a fine filter screen, the swirl flow core, a ceramic atomization sprayer and a self-compacting sealing device. Water flow is filtered by the fine filter screen, so that the sprayer is prevented from being blocked, and at the same time, cleanness and replacement are convenient; fixed-angle rotation and inflowing of the water flow are achieved through the swirl flow core, the water flow is fully mixed and collided to form certain vortex through a sprayer flow mixing cavity, then the water flow is contracted at the vortex sprayer and is sprayed out in an atomized mode, and the abrasion resistance is improved as the atomization sprayer is made of ceramic materials. The efficient and abrasion-resisting nozzle with the swirl flow core is obvious in improving the atomization effect and the abrasion resistance of the sprayer.
Description
Technical field
The present invention relates to a kind of eddy flow core high-efficient atomizing wear resistant spray nozzle, specifically a kind of employing by structure innovation, key parameter optimization and new material realizes nozzle high-efficient atomizing, the nozzle arrangements that improves its wearability and prevent from stopping up.
Background technology
It is the key that realizes the prevention and cure of occupational disease of safety in production pneumoconiosis that coal dust is prevented and treated, and wherein spray precipitation method is the more effective dust-removing method of generally acknowledging at present, and shower nozzle has played decisive role as the key components of realizing final atomization of water current injection to dust-laying effect.Yet effect is unsatisfactory in actual use for the various nozzles of current development, is mainly manifested in the following aspects: the one, and nebulization efficiency is not high, and the 2nd, nozzle often stops up, and the 3rd, nozzle is Fast Wearing in a short time.Therefore the present invention proposes a kind of new version and carried out Parameters Optimal Design, and crucial position easy to wear has adopted ceramic material, thereby improved atomization ability and the wearability of nozzle, and prevented that by the design in preposition meticulous filter screen and crucial aperture nozzle is blocked.
Summary of the invention
Technical problem: the present invention overcome existing colliery not high by atomizing de-dusting nozzle atomization efficiency, easily stop up and deficiency easy to wear, designed a kind of high-efficiency atomizing nozzle of simple in structure, anti-blocking resistant wear, for the atomizing de-dusting of coal mine work area.
Technical scheme: a kind of eddy flow core high-efficient atomizing wear resistant spray nozzle, comprises meticulous filter screen, eddy flow core, ceramic spray head, O RunddichtringO and nozzle body.The nozzle body water inlet end of described nozzle is passing hole, and water side is processed with seal groove, and O RunddichtringO is fitted in seal groove; Ceramic spray head water side is pressed in nozzle body by O RunddichtringO; The water inlet end of eddy flow core and ceramic spray head fits tightly; Eddy flow core is with ceramic spray head interference fit and keep coaxial; Meticulous filter screen is fixed in nozzle body and is close to eddy flow core by the mode of rubber seal.
Eddy flow core is comprised of central through hole and the angle inclined hole of determining that is distributed in cylinder surrounding, by adjusting the angle of inclined hole, can control the mixed flow intensity of current in mixed flow chamber, and the angle reasonable value scope of determining angle inclined hole is 30 ° ~ 60 °.
Ceramic spray head by thering is the mixed flow chamber of certain draw ratio, the spray-hole that has the contraction section of certain angle and have a certain pore size forms, and made by ceramic material, wearability improves, the draw ratio scope in mixed flow chamber is 0.6 ~ 1, the size in outgoing aperture coordinate pressure of supply water can control water consumption number.
Nozzle carries out single filter by preposition meticulous filter screen to current, by eddy flow core central through hole with determine the aperture of angle inclined hole and the design in spray-hole aperture prevents that impurity from entering nozzle, thereby is easy to nozzle cleaning, prevents spray nozzle clogging.
Described technical scheme can improve the atomizing effect of outgoing current by eddy flow core greatly to the optimization in incident angle, ceramic nozzle mixed flow chamber draw ratio and outgoing aperture and coupling, improves the ability of atomizing de-dusting.
The present invention has following advantage: 1) nozzle arrangements is simple, and volume is little, adopts modular connection to be connected with supply channel, is easy to install and use on the various device of down-hole.2) spray effect is good, and atomizing particle is moderate, and the demand that can meet depositing dust can guarantee certain jet length again.3) long service life, stifled and wear-resisting owing to being difficult for, greatly improve average life.
