The medium coarse particles which cannot pass through the classifying device and cannot meet the fineness requirement of the finished product can form air flow disturbance due to collision of downward gravity and upward conveying wind force, and the medium coarse particles suspend in the air to block a rising channel of the finished product meeting the fineness requirement, so that the productivity is reduced, and the energy consumption is increased.
2. High energy consumption. Powder separators in the market are commonly in machine top feeding, and the feeding height and the feeding amount are both at the cost of electric energy loss.
3. Black slag is easy to generate, and the separation purity is not high. The materials to be separated often contain black slag, and the existing powder selecting device generally uses mechanical force to disperse at high speed in the powder selecting process, so that the black slag is secondarily ground, and the black slag meeting the fineness requirement is separated and mixed into a finished product, thereby influencing the purity of the finished product.

Detailed Description
The technical scheme of the invention is further described below with reference to the embodiment shown in the drawings.
The invention relates to an energy-saving environment-friendly high-efficiency powder concentrator, which comprises a separating cylinder 1, an air inlet pipe 2, a rotor 5, a separating cylinder 6, a negative pressure exhaust pipe 3 and an air deflector 7.
The separating cylinder 1 comprises a cylindrical cylinder body I on the upper part and an inverted cone-shaped cylinder body I on the lower part, wherein a qualified powder discharge port is coaxially formed in the top of the cylindrical cylinder body I, the qualified powder discharge port is communicated with a negative pressure exhaust pipe 3 arranged on the top of the cylindrical cylinder body I, a rotor 5 driven by an external cylinder motor 11 is coaxially arranged in the cylindrical cylinder body I below the qualified powder discharge port, and a slag hole I4 is formed in the bottom cylinder opening of the inverted cone-shaped cylinder body I, as shown in fig. 1.
The air inlet pipe 2 (connecting fan) is horizontally arranged at the lower part of the cylindrical barrel I of the separating barrel 1 (the bottom of the air inlet pipe 2 is parallel and level to the lower end barrel mouth of the cylindrical barrel I), the air inlet pipe 2 is communicated with the separating barrel 1 in a tangential mode with the cylindrical barrel I, and a feed inlet 10 is formed in the cylindrical barrel I at the top of the air inlet pipe 2, as shown in fig. 1.
The separating cylinder 3 is coaxially arranged in the separating cylinder 1, the separating cylinder 3 comprises a cylindrical cylinder II at the upper part and an inverted cone cylinder II at the lower part, the cylindrical cylinder II is coaxially arranged in the cylindrical cylinder I, the upper end cylinder opening of the cylindrical cylinder II is positioned below the rotor 5 and has a diameter larger than that of the rotor 5, the lower end cylinder opening of the cylindrical cylinder II is flush with the lower end cylinder opening of the cylindrical cylinder I, an annular cavity is formed between the cylindrical cylinder II and the cylindrical cylinder I, a louver-shaped fence plate 12 (with functions of upper wind guiding and downward blanking) is arranged at the lower end cavity opening of the annular cavity, the bottom cylinder opening of the inverted cone cylinder II is a slag outlet II 8, the slag outlet II 8 is communicated with a blanking pipe 9, and the blanking pipe 9 is obliquely downwards communicated with the inverted cone cylinder I, as shown in fig. 1.
The air deflectors 7 are uniformly distributed on the circumference of the upper part (higher than the feeding hole 10) of the annular cavity, and each air deflector 7 can synchronously adjust the angle so as to control the wind speed passing through the annular cavity, as shown in figure 1.
The operation mode of the invention is as follows:
The fan starts, and the material gets into from feed inlet 10, blows in the gas in annular chamber from air-supply line 2 and breaks up the material for the first time, and the wind that gets into has two kinds of trends that upwards and downward move, and fence board 12 has stopped the trend of wind direction downmovement, therefore, the air inlet forms ascending spiral wind in annular chamber, and a part of granule diameter between 50 mesh ~ 5mm is because gravity and centrifugal force effect is direct through fence board 12 or accumulated to the section of thick bamboo wall and is fallen and drop to the back taper barrel I of separating drum 1 through fence board 12 and discharge and collect from slag notch I4 again.
The gas carries the granule to rise in annular chamber rotation, and the material is broken up by the second time when gas passes through the air intake of air-supply line 2, and like the first time breaks up, through the regulation of aviation baffle 7 to rotation direction and rotational speed, the big granule of diameter between 50 mesh ~ 5mm is accumulated on the section of thick bamboo wall and is dropped and is discharged from slag notch I4 through fence plate 12 under the effect of centrifugal force and collect owing to the centrifugal force most before getting into the powder selecting area, and other granule is carried rotatory rising by gas.
When the air rises to the position of the air deflector 7, the air passing speed is regulated by regulating the angle of the air deflector 7, after the air speed is increased, small particles can reach the vicinity of the rotor 5 through the air deflector 7, and large particles which do not pass through the air deflector 7 are thrown to the wall of the cylindrical barrel I to be accumulated and slide down, discharged through the slag outlet I4 and collected.
The rotor 5 screens particles passing through the air deflector 7, qualified materials with 300 meshes are sucked into the negative pressure exhaust pipe 3 and collected, medium-diameter particles with 200 meshes to 50 meshes are deposited at the lower end of the rotor 5 due to insufficient granularity and then fall into the cylindrical barrel II of the inner separating barrel 6, and are discharged and collected from the slag hole II 8 at the bottom of the inverted cone barrel II through the discharging pipe 9.
As no mechanical force acts on the material particles in the whole running process, the particles are not crushed secondarily, black particles are not crushed, the black particles are collected at the slag outlet I4 and the slag outlet II 8, and the black slag in qualified powder is greatly reduced, so that the separation purity is improved.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limited thereto. Any modifications and substitutions of the embodiments herein described, which would be apparent to those skilled in the art without departing from the principles of the invention, are intended to be within the scope of the invention.
