The powder concentrator is widely applied in the powder processing industry, and the first powder concentrator produced in 1885 is a centrifugal powder concentrator which separates materials by utilizing the difference of centrifugal force and gravity of particles; the second generation powder concentrator, namely a cyclone type powder concentrator, appears in 1960, and the problems of low powder concentration efficiency, low powder concentration precision and the like of the first generation powder concentrator are solved; in 1979, a high-efficiency powder concentrator was produced, and a cage type powder concentrator represented by a 0-SEPA powder concentrator is called the high-efficiency powder concentrator, overcomes the defects of uneven material scattering, uneven flow distribution air field and the like of a centrifugal type powder concentrator and a cyclone type powder concentrator, and is the most efficient and advanced powder concentrator on the market at present.

However, the efficient powder concentrator still has the following problems when in use:

1. low separation rate and low productivity. The medium coarse particles which cannot meet the fineness requirement of the finished product and cannot pass through the grading device are suspended in the air to block an ascending channel of the finished product meeting the fineness requirement due to the fact that downward gravity and upward conveying wind power collide to form airflow disorder, and the medium coarse particles reduce the capacity and increase the energy consumption.

2. The energy consumption is high. The powder selecting machine on the market is generally used for feeding from the top of the machine, and the feeding height and the feeding amount are both at the cost of electric energy loss.

Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The utility model discloses energy-concerving and environment-protective high-efficient selection powder machine, including cylinder 1, air-supply line 2, rotor 5, interior cylinder 6, negative pressure blast pipe 3 and aviation baffle 7.

The separating cylinder 1 comprises a cylindrical cylinder body I on the upper portion and a reverse taper cylinder body I on the lower portion, a qualified powder discharge port is coaxially formed in the top of the cylindrical cylinder body I, a negative pressure exhaust pipe 3 is arranged on the top of the qualified powder discharge port communicated with the cylindrical cylinder body I, a rotor 5 driven by an outer cylinder motor 11 is coaxially arranged in the cylindrical cylinder body I below the qualified powder discharge port, and a bottom cylinder opening of the reverse taper cylinder body I is a slag outlet I4 and is shown in figure 1.

The lower part of the cylindricality barrel I of the knockout drum 1 is located to air-supply line 2 (connection fan) level (the bottom parallel and level of air-supply line 2 is in the lower extreme tube socket of cylindricality barrel I), and air-supply line 2 communicates knockout drum 1 with the tangent mode with cylindricality barrel I, has seted up feed inlet 10 on the cylindricality barrel I at air-supply line 2 top, as shown in fig. 1.

In interior separation cylinder 3 coaxial locating separation cylinder 1, interior separation cylinder 3 includes the cylindricality barrel II on upper portion and the back taper barrel II of lower part, II coaxial locating cylindricality barrels in I, the upper end nozzle of cylindricality barrel II is in rotor 5 below and the diameter of diameter more than rotor 5, and the lower extreme nozzle parallel and level of cylindricality barrel II forms the annular chamber between II and the cylindricality barrel I in the lower extreme nozzle of cylindricality barrel, the lower extreme nozzle department of annular chamber is equipped with shutter form's fence board 12 (has the function of last wind-guiding and downward blanking), the bottom nozzle of back taper barrel II is slag notch II 8, slag notch II 8 link to each other unloading pipe 9, unloading pipe 9 leads to down back taper barrel I to one side, as shown in figure 1.

The air deflectors 7 are uniformly distributed on the upper part (higher than the feeding hole 10) of the annular cavity at the circumference, and the angles of the air deflectors 7 can be synchronously adjusted so as to control the air speed passing through the annular cavity, as shown in figure 1.

The utility model discloses an operation mode does:

the fan starts, the material gets into from feed inlet 10, blow in the gas of annular chamber from air-supply line 2 and break up the material for the first time, the wind of entering has upwards and two kinds of motion trends down, barrier plate 12 has blockked the trend of wind direction downstream, consequently, the air inlet forms ascending spiral shell whirlwind in the annular chamber, the granule of partly material diameter between 50 meshes ~ 5mm is owing to gravity and centrifugal force effect directly through barrier plate 12 or accumulate to the section of thick bamboo wall landing again and drop to the back taper barrel I of separator 1 and follow slag notch I4 discharge collection through barrier plate 12.

The gas carries particles to rise in the annular cavity in a rotating mode, when the gas passes through the air inlet of the air inlet pipe 2, materials are scattered for the second time, like the first scattering, through the adjustment of the air deflector 7 on the rotating direction and the rotating speed, most of large particles with the diameter of 50 meshes-5 mm are accumulated on the wall of the cylinder under the action of centrifugal force before entering the powder selecting area, fall off through the fence plate 12 and are discharged from the slag outlet I4 for collection, and the rest particles are carried by the gas to rise in a rotating mode.

When the gas rises to the position of the air deflector 7, the speed of the gas passing through is adjusted by adjusting the angle of the air deflector 7, when the wind speed is increased, small particles can reach the position near the rotor 5 through the air deflector 7, and large particles which do not pass through the air deflector 7 are thrown onto the wall of the cylindrical barrel I, stacked and slide down, discharged through the slag outlet I4 and collected.

The rotor 5 screens the particles passing through the air deflector 7, qualified materials of about 300 meshes are sucked into the negative pressure exhaust pipe 3 and collected, and medium-diameter particles of 200-50 meshes are not sucked into the negative pressure exhaust pipe 3 due to insufficient particle size, fall into the cylindrical barrel II of the inner separation barrel 6 after being accumulated at the lower end of the rotor 5, and are discharged and collected from a slag outlet II 8 at the bottom of the inverted conical barrel II through the discharging pipe 9.

Because the whole course of operation does not have any mechanical force to act on the material granule, consequently can not cause the regrinding to the granule, just can not smash black granule yet, black granule is collected at slag notch I4 and slag notch II 8, and the black sediment in the qualified powder just significantly reduces to separation purity has been improved.

The above-mentioned embodiments are only used for explaining the technical solution of the present invention, and do not limit it. Any modification and replacement of the embodiments that may occur to those skilled in the art without departing from the principles of the present invention are within the scope of the present invention.
