Abstract
The utility model discloses a vertical shaft type coal mill. The vertical shaft type coal mill comprises a base and a shell, wherein a motor and the shell are arranged on the base; the motor is positioned on the left side of the base, and is connected with a shaft through a coupling; a plurality of rotors which are arranged in parallel are arranged on the shaft; the shell is sleeved on the rotors; a vertical shaft is arranged above the shell; a coal briquette inlet through which coal briquettes are fed is formed in one side of the vertical shaft; and a nozzle is formed in the upper end of the vertical shaft. According to the utility model, a classifier is omitted, the structure is simplified, and the vertical shaft type coal mill is compact in structure, and convenient to install and maintain. Due to low air flow speed, the improved coal mill is low in resistance and low in power consumption.
Description
Technical field
The utility model relates to a kind of coal pulverizer, relates in particular to a kind of impact mill.
Background technology
High speed coal mill commonly used at present is fan mill and impact mill.The shortcoming of fan mill is complex structure, power consumption height; And the shortcoming of existing impact mill is because device is big, installation is wasted time and energy, inconvenient maintenance, and power consumption is also higher.
The utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model provides a kind of impact mill.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of impact mill, comprise base, shell, and base is provided with motor and shell, and motor is positioned at the left side; Motor is connected with axle by shaft coupling;
Axle is provided with a plurality of rotors that are arranged in parallel; Shell is nested with on rotor; The top of shell is provided with vertical shaft, and a side of vertical shaft is provided with the coal cinder inlet that is used to put into coal cinder; The upper end of vertical shaft is a spout.
The utility model has saved mill separator, simplifies the structure, structure is compact more, and installation, maintenance is also more convenient, and the coal pulverizer after the improvement is lower because of the speed of air-flow, and resistance is little, and the electricity consumption power consumption is also lower.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, shell; 2, rotor; 3, axle; 4, shaft coupling; 5, motor; 6, coal cinder inlet; 7, vertical shaft; 8, spout; 9, base.
The specific embodiment
As shown in Figure 1, the utility model mainly comprises shell 1, rotor 2, axle 3, shaft coupling 4, motor 5, coal cinder inlet 6, vertical shaft 7, spout 8 and base 9.
Operation principle of the present utility model: the utility model is directly driven by motor, coal enters the back by the coal cinder of vertical shaft one side inlet soon and is ground by the high speed rotor rotated, and rotor is finished grinding of coal cinder to the spreading and the broken coal of the coal that accumulates in the bottom to the bump of shell.Hot-air enters from the bottom of vertical shaft, on the one hand the coal dust that grinds is carried out drying, plays the effect of separation and pulverized coal conveying on the one hand.This novel mill separator that is not provided with send into burner hearth and with the speed of the air-flow in the control vertical shaft qualified fine breeze is separated, and thicker coal dust side dependence gravity fall is pulverized by coal pulverizer once more.
