Abstract

The utility model discloses a graphite sleeve. On the basis of the prior art, the thickness (1) of the graphite sleeve is reduced to 80 millimeters, and the diameter (d) of a liquid inlet is enlarged to phi 85 millimeters. By using the graphite sleeve, the amount of aluminum liquid which flows through the graphite sleeve is increased, the time that the aluminum liquid passes through the graphite sleeve is shortened, the high temperature of an atomizer during atomizing is ensured, a spray nozzle is not easy to block, and the continuity of production is ensured.

Description

Graphite cannula
Technical field
The utility model relates to a kind of graphite cannula, especially relates to the graphite cannula of using in a kind of production of aluminum powder process.
Background technology
Aluminium liquid atomizing operation in the production of aluminum powder process, 750 ℃-820 ℃ aluminium liquid are to get into atomizer through the graphite trepanning to atomize.Existing graphite cannula is honest and kind to be 90mm, and the inlet diameter of graphite trepanning is φ 60mm, but this graphite cannula thickness is thick partially; The graphite trepanning is less than normal, aluminium flow impurity in the aluminium liquid when graphite pores be deposited on graphite pores around, cause interior hole plug in the short period of time; Because endoporus is less than normal blocked up with thickness, the aluminium flow in the stove is little through the graphite cannula amount, and is longer through the graphite cannula time again; Temperature is low during through atomizer, is prone to plug nozzle, causes stopping production.
The utility model content
The purpose of the utility model is the deficiency to prior art, and a kind of graphite cannula that in the production of aluminum powder process, is difficult for stopping up trepanning, production continuity, good stability is provided.
The purpose of the utility model is achieved in that it is that graphite cannula thickness is narrowed down to 80mm, and the inlet diameter changes big to φ 85mm.
The beneficial effect of the utility model has been to increase the aluminium liquid measure of graphite cannula of flowing through, and has shortened the time of aluminium liquid through graphite cannula, and temperature is high when guaranteeing the atomizer atomizing, is difficult for plug nozzle, guarantees the production continuity.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of existing graphite cannula;
Fig. 2 is the structural representation of the utility model graphite cannula.
The specific embodiment
Embodiment:
As shown in Figure 2, the utility model graphite cannula narrows down to 80mm with original graphite cannula thickness l by original 90mm, and the inlet diameter d is changed big to φ 85mm by φ 60mm.

Claims (1)

1. graphite cannula, it is characterized in that: it is that graphite cannula thickness (1) is narrowed down to 80mm, inlet diameter (d) changes big to φ 85mm.
