Abstract

The utility model relates to an airflow pulverizer and classifier apparatus, and particularly relates to air intakes of a diamond airflow jet mill and classifier. The air intakes of the airflow pulverizer and classifier comprise a pulverizing cavity and a feeding pipe. A first air intake pipe, a third air intake pipe and a fifth air intake pipe are uniformly distributed on the outer wall at the bottom of the pulverizing cavity. The air intakes of the airflow pulverizer and classifier are characterized in that a second air intake pipe, a fourth air intake pipe and a sixth air intake pipe are uniformly distributed on the same horizontal surface with the first intake pipe, the third air intake pipe and the fifth air intake pipe. Each air intake pipe forms a 45-degree angle with the pulverizing cavity. Six air intake pipes are adopted, so that impact force of the airflow can be enhanced; a phenomenon that a diamond raw material falls back repeatedly and impacted again is prevented. Since each air intake pipe forms a 45-degree angle with the pulverizing cavity, the high pressure airflow forms high pressure whirlpool in the pulverizing cavity, the diamond raw materials can be abraded sufficiently, and the rate of finished products is increased remarkably.

Description

A kind of jet mill grinding machine air inlet

[technical field]

The utility model relates to a kind of airflow crush grading plant, particularly a kind of diamond jet mill grinding machine air inlet.

[background technology]

Air-flow crushing split pole machine plays an important role in the diamond shaping process, its operation principle is: compressed air enters the air-flow crushing cavity by jet pipe, the diamond raw material of shaping is not driven by air-flow and mutually clashes into, rubs and pulverize in the air-flow crushing cavity, entered grading plant by the diamond after pulverizing with air-flow and carry out the classification processing, qualified fine powder is carried by ascending air and enters finished product and collect feed bin, and meal falls back to grading plant under Action of Gravity Field bottom is fallen in the air-flow crushing cavity via the feed back pipe and again pulverized.

At present, the pulverizing cavity bottom of jet mill grinding machine has 4 air inlets, level is distributed on cavity inner wall, two relative air inlets are vertically opposite, the gases at high pressure level of 4 air inlet ejections is met on the axis of pulverizing cavity, form powerful impact, but from the axis more away from, impact and frictional force are just less, cause the rear shaping of diamond raw material pulverizing insufficient, and large content of starting materials often needs repeatedly to repeat falling and again clashes into, caused crushing phenomenon, cause yield rate to reduce, production cost is high, and production efficiency reduces.

[utility model content]

For addressing the above problem, the utility model provides a kind of jet mill grinding machine air inlet.

The utility model for achieving the above object, the technical scheme of employing is as follows:

A kind of jet mill grinding machine air inlet, comprise and pulverize cavity, feed pipe, the first air inlet pipe, the 3rd air inlet pipe, the 5th air inlet pipe level are distributed on the outer wall of pulverizing cavity bottom, it is characterized in that: be evenly equipped with the second air inlet pipe, the 4th air inlet pipe, the 6th air inlet pipe on the first air inlet pipe, the 3rd air inlet pipe, the 5th air inlet pipe same level, the first air inlet pipe and the second air inlet pipe interval 5cm, the 3rd air inlet pipe and the 4th air inlet pipe interval 5cm, the 5th air inlet pipe and the 6th air inlet pipe interval 5cm.Aforementioned the first air inlet pipe, the second air inlet pipe, the 3rd air inlet pipe, the 4th air inlet pipe, the 5th air inlet pipe, the 6th air inlet pipe are 45° angle with the inwall of pulverizing cavity.

Adopt technique scheme, owing to having adopted 6 air inlet pipe, and two strands of high pressure draughts with the aspect of every air inlet pipe ejection, gas shock power is increased, can make the diamond raw material clash into fast pulverizing, reduced and repeated to fall after rise the phenomenon of again clashing into; And because every air inlet pipe and the inwall of pulverizing cavity are 45° angle, make high pressure draught form the high pressure whirlpool in pulverizing cavity, can make fully friction between the diamond raw material, significantly improve yield rate.
