Abstract

The utility model belongs to discharging devices, is mainly applied to industries such as cement, chemical engineering and metallurgy and particularly relates to a discharging device of a roller type mill. According to the discharging device of the roller type mill, parts of materials milled by the roller type mill overflows from the circumference of a millstone into an discharging channel which is composed of an inner cylinder, an outer cylinder and a material guiding bottom plate; under the action of down-sliding force generated by gravity, the materials on the large-dip-angle material guiding bottom plate can slide from upper to lower along the inclined plane of the material guiding bottom plate and is discharged from a lower discharging port; meanwhile, a vibrator on the material guiding bottom plate vibrates periodically at intervals, so that material stacking due to wet materials on the material guiding bottom plate can be avoided. According to the discharging device of the roller type mill, a traditional passive scraping board unloading mode can be omitted; by means of the large-dip-angle bottom plate, materials can slide on the material guiding bottom plate from upper to lower towards the discharging port under the action of the down-sliding force generated by gravity; due to the fact that the friction force between the materials and the cylinder body during the down-sliding process, the abrasion of the inner cylinder, the outer cylinder and the bottom plate is small, the equipment maintenance cost can be saved, the labor intensity of workers can be reduced, the running rate of the roller type mill can be improved and the power consumption of the roller type mill during the running process is reduced.

Description

A kind of roller mill device for discharging

Technical field

The utility model belongs to a kind of device for discharging, is mainly used in the industries such as cement, chemical industry, metallurgy, particularly a kind of roller mill device for discharging.

Background technology

The utility model content

The purpose of this utility model is to provide a kind of roller mill device for discharging that overcomes above-mentioned defect, has both reduced the transmission energy consumption, reduces again component wear, improves roller mill running rate.

The technical solution of the utility model is: a kind of roller mill device for discharging comprises:

Inner core, its internal diameter are less than the mill external diameter, and be coaxial with mill, suitable for reading and mill go to the bottom from; And and mill between sealing strip is housed;

Urceolus, it is coaxial with inner core, and upper limb is higher than plane on mill, and the annular space between inner core and urceolus forms the discharge channel of the rear material of mill;

The guide base plate, it has two kinds of forms: in-line plane cut sth. askew urceolus and inner core, base plate cuts out from the low side of 180 ° of directions of point of penetration again from the high-end incision of urceolus, is mainly used in small-sized roller mill discharging; Herringbone plane cut sth. askew urceolus and inner core, the herringbone plane intersection line on the shaft section of inner core and urceolus, cuts out from the low side of 90 ° of directions of high-end point of penetration, is mainly used in large-scale roller mill discharging;

Discharge port, the one end communicates with the dumping pit at guide base plate and the outer cylinder body low side place of cutting out;

Vibrator, it is arranged on base plate, the Timing vibration Anti-caking.

The low side place of cutting out of described guide base plate and urceolus opens dumping pit, guide base plate inner edge and inner core are bolted together, outer rim and urceolus are bolted together, and the angle of guide base plate high inclination-angle inclined-plane and horizontal plane is the 40-60 degree, and abrasion-proof backing block is arranged at base plate top.

Operation principle of the present utility model is: the partial material after the roller mill grinding is overflowed the discharge channel that enters inner core, urceolus and guide base plate composition from the mill surrounding, material is under the effect of the sliding force that relies on gravity to produce on the guide base plate of high inclination-angle, glide from high to lower along the guide bottom board inclined plane, draw off from the discharge port of bottom, base plate upper vibration generator fixed time interval vibration simultaneously, can prevent that the ramming material phenomenon when base plate runs into wet stock from producing.

The beneficial effects of the utility model are, a kind of roller mill device for discharging of the utility model, abandon traditional material scraping plate and forced discharging, adopt high inclination-angle guide base plate, the sliding force that material relies on gravity to produce acts on the guide base plate and slides into discharge port under freedom, due to little with the frictional force of cylindrical shell in the supports for material down-sliding process, thereby the wearing and tearing of inner core, urceolus and base plate are little, saved the maintenance cost of equipment, alleviated workman's labour intensity, improve simultaneously the running rate of roller mill, also reduced the power consumption in the roller mill operation process.
