Description
Technical Field
The utility model belongs to the technical field of fluid gasification equipment, a adjustable nozzle structure is related to.
Background
In chemical enterprises using the coal water slurry as a raw material, a nozzle is the key of coal water slurry gasification, and the nozzle is very easy to damage due to the application of the nozzle in high-pressure, high-temperature and heterogeneous environments. The nozzles in the united states were originally introduced by the industry and had an average life of 2 months and were replaced. After many years of exploration, the improved nozzles used in the current industry are replaced by one batch in 6 months. The cost is high, and the problems are also existed when the nozzle is applied to other industries.

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
In the drawings 1-7, the device comprises a cylinder body 1, an upper cavity 1-1, a lower cavity 1-2, a knurled part 1-3, a sealing plate 2, a gasket 3, a fastener 4, a nozzle 5, a spring washer 6 and the like.
As shown in fig. 1-7, the utility model relates to an adjustable nozzle structure, including barrel 1, coaxial upper portion cavity 1-1, the lower part cavity 1-2 that link up of axial set up on barrel 1, barrel 1 lower part terminal surface fastening connection shrouding 2, form spout 5 between barrel 1 lower part terminal surface and the shrouding 2.
As shown in fig. 1, a gasket 3 is provided between the lower end surface of the cylinder 1 and the upper surface of the sealing plate 2, and the gasket 3 is a semi-annular metal sheet.
As shown in fig. 7, the fastening member 4 is a connecting bolt, and a spring washer 6 is provided between a bolt head of the connecting bolt and the upper end surface of the cylinder 1.
As shown in figure 2, a circle of knurled parts 1-3 is arranged on the circumferential surface of the cylinder body 1, the cylinder body 1 is made of wear-resistant metal, and the knurled parts 1-3 are used for clamping a wrench in use.
As shown in FIG. 2, the inner diameter of the upper chamber 1-1 is smaller than that of the lower chamber 1-2.
The utility model discloses connecting hole quantity on the shrouding 2 in the product corresponds the cooperation with the connecting hole on the gasket 3, and the size of spout 5 has been decided to the breach of gasket 3, when specifically using, according to using the place needs, selects gasket 3 of suitable thickness to satisfy operation requirement.
The utility model discloses the product can be effectively be suitable for with water coal or other trades, when the parking is overhauld, as long as change gasket 3 can, effectively reduce nozzle structure's use cost.
The utility model discloses the theory of operation of product: when the coal water slurry gasification device works, high-temperature and high-pressure coal water slurry enters from the upper cavity 1-1, and is sprayed and gasified from a nozzle 5 formed between the cylinder 1 and the sealing plate 2 under the action of the metal gasket 3 with the semi-ring structure.
