Abstract

The utility model discloses a shoveling cutter of a flour mill. The shoveling cutter comprises a shoveling cutter base in a horizontal direction and a shoveling cutter body fixedly connected onto the shoveling cutter base, wherein an arc-shaped rear end air-guiding plate and an arc-shaped outer side air-guiding plate, which are incurved inwards, are arranged at the rear end and on the outer side surface of the shoveling cutter body respectively. The shoveling cutter has the advantages that the obstruction force of the shoveling cutter to airflow is decreased due to the rear end air-guiding plate and the outer side air-guiding plate on the shoveling cutter body, so that kinetic energy of partial rotary airflow in translational motion is converted into rising kinetic energy, generated turbulent flow and the loss of kinetic energy of airflow are reduced, the abrasion, caused by the blowing materials via airflow, of the shoveling cutter is alleviated, and the service life of the shoveling cutter is prolonged.

Description

Flour mill perching knife

Technical field

The utility model relates to flour mill field, especially relates to a kind of flour mill perching knife.

Background technology

Flour mill is widely used in the pulverizing of the industries such as mine, chemical industry, building, abrasive material and various dry powder class materials, and when material enters after mill chamber, perching knife scoops up material to send between grinding roller and bull ring and rolls.Because traditional perching knife is planar structure, in flour mill running, perching knife surface is affected by gas-flow resistance, can produce turbulent flow, the local disturbance producing at turbulent flow is serious, wind speed increases, and kinetic energy rejection is large, and then make the serious wear of this place's perching knife, shorten its service life.

Summary of the invention

The utility model object is to overcome the deficiencies in the prior art, provide a kind of gas-flow resistance little, reduce wear, the flour mill perching knife of long service life.

For achieving the above object, the utility model can be taked following technical proposals:

Flour mill perching knife described in the utility model, comprise the perching knife attic base of along continuous straight runs setting and be connected in the perching knife body on described perching knife attic base, at rear end and the lateral surface of described perching knife body, be respectively arranged with aduncate arc rear end wind deflector and outside wind deflector.

Bottom place's tangential direction of described rear end wind deflector and outside wind deflector and the angle α of horizontal direction are 15 °～75 °.

The utility model advantage is by rear end wind deflector and outside wind deflector are set on perching knife body, reduce the obstruction of perching knife to air-flow, part translation rotating airflow kinetic energy is converted into rising kinetic energy, turbulent generation and the loss of airflow kinetic energy have been reduced, thereby reduced air-flow and blown the wearing and tearing of material to perching knife, the service life of having improved perching knife.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the top view of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, flour mill perching knife described in the utility model, comprise the perching knife attic base 1 of along continuous straight runs setting and be connected in the perching knife body 2 on described perching knife attic base 1, rear end and lateral surface at described perching knife body 2 are respectively arranged with aduncate arc rear end wind deflector 3 and outside wind deflector 4, for further guaranteeing its wind-guiding result of use, bottom place's tangential direction of described rear end wind deflector 3 and outside wind deflector 4 and the angle α of horizontal direction are designed to 15 °～75 °; The utility model is by arranging rear end wind deflector 3 and outside wind deflector 4, reduce the obstruction of perching knife to air-flow, part translation rotating airflow kinetic energy is converted into rising kinetic energy, reduce turbulent generation and the loss of airflow kinetic energy, thereby reduced air-flow and blown the wearing and tearing of material to perching knife, the service life of having improved perching knife.

Claims

1. a flour mill perching knife, comprise the perching knife attic base (1) that along continuous straight runs arranges and be connected in the perching knife body (2) on described perching knife attic base (1), it is characterized in that: rear end and lateral surface at described perching knife body (2) are respectively arranged with aduncate arc rear end wind deflector (3) and outside wind deflector (4).

2. flour mill perching knife according to claim 1, is characterized in that: bottom place's tangential direction of described rear end wind deflector (3) and outside wind deflector (4) and the angle α of horizontal direction are 15 °～75 °.
