Abstract
The utility model discloses a tungsten carbide nozzle which belongs to the field of spray drying equipment in the mechanical field. The utility model adopts a tungsten carbide material to make the nozzle, and improves the structure so as to obtain the tungsten carbide nozzle adaptable to high-pressure spray. The tungsten carbide nozzle comprises a protective casing and a nut, wherein a tungsten carbide nozzle core is inserted into the protective casing and then the nut is screwed up on the protective casing. The tungsten carbide nozzle is characterized in that the nozzle not only adopts tungsten carbide as the material of the nozzle core to greatly improve abrasion resistance, but also is structurally improved as compared with the prior nozzle.
Description
Technical field:
The utility model belongs to the spray drying device field in the mechanical field.
Background technology:
In spray drying device, the liquid material nozzle is in down ejection of high pressure (greater than 30MPa), presents vaporificly on the drying tower top, and becomes powder at the tower inner drying, realizes drying purpose.And traditional metallic nozzle wearability is very poor, and it is very fast to wear and tear in the use, and frequent the replacing brought a lot of inconvenience, and influence production efficiency, though the ceramic nozzle wearability is better, because of toughness too poor, under high pressure often brittle failure is burst apart, and also can't satisfy the requirement of high-pressure spray-drying.And traditional nozzle is to connect with containment vessel by interference fit with a round tablet, because of can not effectively compressing, nozzle core in use usually occurs and moves relative to protecting to rotate or go here and there.
Summary of the invention:
Thereby the utility model adopts tungsten carbide material to make nozzle and has improved structure and reaches the tungsten carbide nozzle that adapts to high-pressure fog.
The utility model comprises containment vessel, nut, and the tungsten carbide nozzle core is inserted in the containment vessel, then nut is screwed on the containment vessel.
Two spheres on the top of the utility model tungsten carbide mouth core are concentric circles.
The utility model is equipped with seal washer between nut and tungsten carbide nozzle core.
Characteristics of the present utility model are removed and are adopted tungsten carbide as the nozzle core material, improve greatly outside the anti-wear performance, with conventional spout improvement is arranged also on the structure, the one, two spheres of tungsten carbide nozzle core adopt two homocentric spheres, this make two spheres everywhere wall thickness equate, reach the equal strength purpose; The 2nd, nozzle core is to be pressed in the containment vessel by being threaded, and can prevent rotating and axial motion relative to containment vessel when the tungsten carbide nozzle core is under high pressure worked like this.
Description of drawings:
Accompanying drawing is the utility model structure cutaway view.
The specific embodiment:
The utility model comprises containment vessel 2, nut 4, and tungsten carbide nozzle core 1 is inserted in the containment vessel 2, then nut 4 is screwed on the containment vessel 2.
Two spheres on the top of the utility model tungsten carbide mouth core 1 are concentric circles.
The utility model is equipped with seal washer 3 at nut 4 and 1 in tungsten carbide nozzle core.
Tungsten carbide nozzle 1 of the present utility model is fitted together with containment vessel 2 precision-fit, and nut 4 compresses tungsten carbide nozzle core 1 by seal washer 3, prevents that it from rotating or axial motion under the effect of high-pressure liquid material.Seal washer 3 adopts organic materials, is used for sealing, and prevents that liquid material under high pressure runs off and minimizing pressure from the gap of 1 in containment vessel 2 and tungsten carbide nozzle core.Tungsten carbide nozzle core 1 top is two concentric sphericals, and sphere cuts out the through-flow otch of desired angle and width on request, changes angle and width and can change flow.Liquid material under high pressure flows into from the centre bore of tungsten carbide nozzle core 1, and the otch ejection through tungsten carbide nozzle core 1 forms a fan-shaped vaporific plane.
