Wherein the feeder adopts a screw feeder.
Wherein, the air nozzle is located the below of feed inlet.
Wherein the feeder is provided with a hopper.
Wherein, the motor adopts pneumatic motor or motor.
Wherein, crushing section of thick bamboo bottom is provided with the shutoff lid.
The utility model has the beneficial effects that: the utility model provides a high-efficient jet mill of high accuracy, the raw materials is sent into the feed inlet through the feeder, utilize rotatory blade to cut and pre-smash, avoid big particulate matter unable quick kibbling problem through the air current, promote crushing efficiency, then carry out subsequent crushing through the air current, the fine powder passes through the primary filter screen along with rising air current and gets into the classifying cylinder, carry out further classification, great coarse powder is blocked by the primary filter screen, participate in jet milling once more along with gravity whereabouts, avoid great coarse powder to get into the classifying cylinder, ensure crushing precision.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
The technical solution of the present utility model is further described below with reference to fig. 1 by means of a specific embodiment.
The high-precision and high-efficiency jet mill shown in fig. 1 comprises: crushing section of thick bamboo 5, classifying section of thick bamboo 1, air nozzle 6, blade 4, motor 9, primary filter screen 10 and feeder 3, classifying section of thick bamboo 1 sets up at the top of crushing section of thick bamboo 5, and the material after smashing gets into classifying section of thick bamboo 1, carries out the classification. The crushing section of thick bamboo 5 bottom is provided with shutoff lid 7, and shutoff lid 7 adopts the screw fixation, conveniently dismantles, carries out the maintenance of crushing section of thick bamboo 5.
The feeder 3 is arranged at one side of the crushing cylinder 5, a feed port 11 corresponding to the feeder 3 is arranged on the side wall of the crushing cylinder 5, and in the embodiment, the feeder 3 adopts a screw feeder, so that the feeding is uniform. The feeder 3 is provided with a hopper 2, raw materials are fed into the feeder 3 through the hopper 2, and then are uniformly fed into the crushing cylinder 5 through a feed inlet 11.
The air nozzles 6 are arranged on the outer wall of the classifying cylinder 1 at intervals and extend to the inner side of the classifying cylinder 1, the air nozzles 6 are externally connected with a compressed air supply pipeline, the dried air flow is sent to the air nozzles 6 to be sprayed out, high-speed air flow impact energy is generated, and raw materials are collided and crushed. In this embodiment, the air nozzle 6 is located below the feeding port 11, so that the raw material falling from the feeding port 11 can flow at a high speed through the air nozzle 6, and the crushing efficiency is improved.
In order to avoid the problem that large particles cannot be crushed quickly by air flow, the motor 9 is provided outside the classifying cylinder 1 and is fixed by screws. In this embodiment, the motor 9 is a pneumatic motor or an electric motor, and the rotation speed is high. The motor 9 is internally provided with the rotating shaft 8 extending into the feed inlet 11, the tail end of the rotating shaft 8 is provided with the cutter disc, the blades 4 are arranged on the excircle of the cutter disc at intervals, and the rotating blades 4 are used for cutting and pre-crushing, so that the crushing efficiency is improved, and larger particles can be prevented from directly entering the crushing cylinder 5.
As shown in fig. 1, in order to avoid mixing part of coarse powder into fine powder and passing through the classifying cylinder 1, the primary filter screen 10 is arranged in the pulverizing cylinder 5 and above the feed inlet 11, the fine powder can directly enter the classifying cylinder 1 along with the ascending airflow through the primary filter screen 10 to further classify, the pulverizing precision is improved, the larger coarse powder is blocked by the primary filter screen 10, falls along with gravity and participates in jet milling again, the production efficiency is high, and the application range is wider.
