Abstract
The utility model discloses a K type inner circulation air inlet device for powder selecting machines, which comprises a coarse powder collecting cone, an air inlet pipe and an auxiliary air inlet pipe, wherein the air inlet pipe is arranged on the upper part outside the coarse powder collecting cone; the auxiliary air inlet pipe is composed of a left air pipe and a right air pipe; the left air pipe and the right air pipe are arranged on the outer side surface of the lower part of the coarse powder collecting cone in a central symmetry manner, and are tangential with the outer side surface of the coarse powder collecting cone; the left air pipe and the right air pipe are communicated with the inner part of the coarse powder collecting cone. The utility model sufficiently washes and separates fine powder which is adhered on coarse powder in the powder milling operation course of cement manufacture, and the coarse powder falls into the coarse powder collecting cone of the powder selecting machines.
Description
Technical field
The utility model relates to a kind of in the grinding process of manufacture of cement, and powder granule is carried out the feed arrangement of the powder concentrator of classification by its particle size, circulation powder concentrator air-intake device in particularly a kind of K type.
Background technology
In the grinding process of manufacture of cement, powder granule need be carried out classification by size and handle.Classifying equipoment commonly used at present is the air powder concentrator, and it is a kind of effect by air-flow, makes material particles carry out the equipment of classification by size.Pyatyi separate combination type powder concentrator is the grader that can handle big material in the market, select powder concentration.It contains housing, feed arrangement, dispersion separation chamber, meal collection cone, distribution plenum, whirlwind tube, fines collection awl, air-intake device, circulating fan.Its basic functional principle is: material is entered by feed arrangement and disperses the separation chamber, this chamber is formed by being installed in epitrochanterian spreading disk and counterpunch board etc., material flow on the spreading disk, rotation along with rotor, material has improved uniform situation on spreading disk, and evenly spread to around, strike on the counterpunch board, agglomerating material or thickness powder become the suspended dispersed state, and carry out preliminary dispersion and separate, because the effect of gravity, material is in dispersity falls into branch constituency between wind-guiding leaf and the rotor, under the acting in conjunction of sorting air-flow and rotor rotation, powder granule will be subjected to gravity simultaneously, stream pressure entad and action of centrifugal force, when during greater than centrifugal force, entering in the rotor, enter the whirlwind tube along separate routes via distribution plenum with air-flow than the suffered stream pressure of the material of granule, by the whirlwind tube most of finished product materials is separated, separated air-flow behind most finished products and discharge through outlet and enter circulating fan and carry out inner loop.And contain the superfine powder finished product in this circulating current, and again the part of this circulating current is drawn in the outlet of circulating fan and deliver to follow-up sack cleaner and collect, the fine powder that part is difficult to collect is collected.Simultaneously, owing to discharged a part in the circulating current, auxiliary blast pipe entering part net air is installed in meal collection cone side, thereby has replenished air quantity, reduced the temperature of selecting the powder air-flow, also to falling into the meal collection cone, the fine powder that sticks on the coarse granule cleans separation again simultaneously.Because the axis of symmetry that is arranged on the axis of symmetry of the auxiliary blast pipe on the meal collection cone and meal collection cone substantially at grade, the net air that enters can not form swirling eddy, thereby the fine powder that adheres on the meal that falls into the meal collection cone is cleaned the weak effect of separation.
The utility model content
The technical problems to be solved in the utility model provides circulation powder concentrator air-intake device in a kind of K type, and it has the fine powder that adheres on the meal that falls into the meal collection cone cleans separating effect preferably.
For solving the problems of the technologies described above, circulation powder concentrator air-intake device in the utility model K type, it comprises meal collection cone, blast pipe, auxiliary blast pipe, blast pipe is arranged on the outer top of meal collection cone, described auxiliary blast pipe is made up of left airduct and right airduct, a left side airduct and right airduct are arranged on the center symmetric mode on the bottom lateral surface of meal collection cone and are tangent with the lateral surface of this awl, and left airduct communicates with meal collection cone inside with right airduct air intake.
Because the auxiliary airduct of said apparatus is made up of left airduct and right airduct, and be arranged on the center symmetric mode on the bottom lateral surface of meal collection cone and tangent with the lateral surface of this awl.The net air that enters from left airduct and right airduct can form swirling eddy, thus to the fine powder that adheres on the meal that falls into the meal collection cone clean separate abundant, effective.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of circulation powder concentrator air-intake device in the utility model K type.
Fig. 2 is the upward view of circulation powder concentrator air-intake device in the K type shown in Figure 1.
1. left airducts among the figure, 2. meal collection cone, 3. right airduct, 4. blast pipe.
The specific embodiment
Among Fig. 1, blast pipe 4 is arranged on the outer upper of meal collection cone 3, auxiliary blast pipe is made up of left airduct 1 and right airduct 3, left side airduct 1 and right airduct 3 are arranged on the center symmetric mode on the bottom lateral surface of meal collection cone 2 and are tangent with the lateral surface of this awl, as shown in Figure 2, left airduct 1 communicates with meal collection cone 2 inside with right airduct 3 air intakes.During work, the superfine powder finished product that circulating current contains in the powder concentrator is drawn the part of this circulating current in the exit of circulating fan and to be delivered to follow-up sack cleaner and collect, and the fine powder that part is difficult to collect carries out gas solid separation.Owing to discharged a part in the circulating current, the auxiliary blast pipe of on meal collection cone 2 sides, installing, be left airduct 1 and right airduct 2 entering part net air, because left airduct 1 and right airduct 3 are arranged on the center symmetric mode on the bottom lateral surface of this awl and are tangent with the lateral surface of this awl, make the net air that enters form swirling eddy, clean separation fully to falling into the fine powder that meal collection cone 2 sticks on the coarse granule, thereby effect is better.
Claims (1)
1. circulation powder concentrator air-intake device in the K type, it comprises meal collection cone, blast pipe, auxiliary blast pipe, blast pipe is arranged on the outer top of meal collection cone, it is characterized in that: described auxiliary blast pipe is made up of left airduct and right airduct, a left side airduct and right airduct are arranged on the center symmetric mode on the bottom lateral surface of meal collection cone and are tangent with the lateral surface of this awl, and left airduct communicates with meal collection cone inside with right airduct air intake.
