Abstract

The utility model provides a powder separating machine for a hanging roller type mill, which comprises a powder inlet, a powder outlet, a triangular belt pulley, an impeller shaft, an impeller, a bearing seat, a fixed press cover and a machine body, wherein the impeller is fixed on the impeller shaft, is directly driven to rotate at high speed by a speed adjusting motor through the triangular belt pulley and the direction of the powder inlet is perpendicular to the direction of the powder outlet. When the powder separating machine of the utility model is used, mineral powder with high fineness can be produced through a hanging roller type mill, and the utility model has the advantages of simple structure, convenient maintenance and low production cost.

Description

A kind of powder seperator that is used for the Suspension roller flour mill

The utility model relates to a kind of mine Suspension roller flour mill, especially relates to a kind of powder seperator of Suspension roller flour mill.

At present, 80-325 purpose mineral powder product can only be produced with the Suspension roller flour mill in the mine, is higher than 325 purpose mineral powders and produce, and can only adopt the air-flow disintegrating apparatus, does like this, not only consumes greatly, and involves great expense.The reason that the Suspension roller flour mill can not be produced high fine powder is, the structure of its powder seperator is a Bevel Gear Drive, the rotating speed of impeller is low, the direction of powder inlet and meal outlet is parallel to each other, air communication is crossed powder inlet and is blown into, and is parallel to the blade rotating shaft, and big particle comes out from meal outlet with air-flow easily, and the gap of impeller end face and body is bigger, thereby the powder particle of producing is bigger.Simultaneously, the Bevel Gear Drive mode of powder seperator, complex structure, consumable accessory is many, maintenance difficult.

The purpose of this utility model is exactly in order to provide a kind of simple in structure, easy to maintenance, and can isolate more coarse grained powder seperator, makes the lower Suspension roller flour mill of cost also can produce the mineral powder product of high fineness.

The purpose of this utility model is achieved in that the driven by motor conical gear with original powder seperator, change into directly by the kind of drive of conical gear impeller axle again and rotating by vee-pulley impeller axle by buncher, like this, become the powder inlet of original powder seperator, the direction of meal outlet vertical mutually by being parallel to each other.Impeller is fixed on the impeller shaft, and impeller is rotation at a high speed under the drive of impeller shaft.At the end face of impeller, be provided with mazy groove, at the inner face of stationary gland, also be provided with mazy groove.Like this, mineral powder enters from powder inlet, the impeller that is rotated is at a high speed pulverized, reach under the effect of the air-flow that is blown into from powder inlet than the centrifugal force of coarse granule in the impeller generation of rotation, can not enter the impeller inner chamber, have only thinner powder just can enter the impeller inner chamber, deliver to the whirlwind powder collector with negative-pressure air-flow and collect.Labyrinth type groove between impeller end face and stationary gland inner face more can stop big particle to arrive meal outlet.By regulating the motor revolution, just can obtain the product of different fineness, wheel speed exceedes height, and the fineness of product exceedes height.

With the powder seperator that the utility model provides, simple in structure, easy to maintenance, and can utilize the lower Suspension roller flour mill of cost to produce the mineral powder product of high fineness, greatly reduce production cost.

Below in conjunction with accompanying drawing preferred forms of the present utility model is described in detail:

Accompanying drawing is the profile of powder seperator.

In the accompanying drawing, powder inlet is vertical mutually with the direction of meal outlet, air-flow enters from powder inlet, vee-pulley 1 is rotation at a high speed under the drive of buncher, and impeller axle 2 rotation at a high speed, and the impeller 4 that has some blades is fixed on the impeller shaft 2, rotate with impeller shaft, the end face of blade 4 is provided with mazy groove 7, also is provided with mazy groove 8 on the inner face of stationary gland 6, and stationary gland 6 and bearing block 3 all are fixed by bolts on the body 5.

Claims
