A kind of vertical grinder
Technical field
The utility model relates to a kind of vertical grinder, especially is used for the vertical grinder of grinding material in the cement production industry.
Background technology
The charging aperture of prior art vertical grinder and discharging opening all are arranged on the grinding chamber usually, and the material that need to grind directly passes through discharge hole for discharge after entering grinding chamber and ground from charging aperture.The granularity of the material granule that grinds through this vertical grinder is big, inhomogeneous, flowable is poor, does not meet energy conservation and environment protection.And, since in the grinding-material process no relative measures to the abrasive grains processing of lowering the temperature, so the reduction of the performance of abrasive grains.
The utility model content
Technical problem to be solved in the utility model provides a kind of vertical grinder, and not only granularity is little, even, flowable is good for the material granule after this vertical grinder grinds, and the performance of material itself is not destroyed.
The utility model comprises feeding cylinder, discharging opening, grinding chamber, roller, mill, rotating shaft and frame, the upper end of feeding cylinder is provided with charging aperture, the lower end and the grinding chamber of feeding cylinder are interconnected, and mill is arranged in the bottom of grinding chamber, and the center below mill connects rotating shaft; Arrange that on the card of mill one is the annular groove at center with the mill axle center; The rear end of roller is hinged and connected on the frame, and the front portion cooperation of roller is stuck in the annular groove; A plurality of fountain heads and an air inlet are set on the sidewall of grinding chamber; The top seal connection one of grinding chamber has the lower house of cavity, and the top seal connection one with lower house of cavity has the upper shell of cavity, and discharging opening is arranged on the sidewall of the upper shell with cavity; Feeding cylinder vertically places the above-mentioned lower house that has the upper shell of cavity and have cavity; Feeding cylinder is with outer sleeve outward, the fixedly sleeved driven gear in the top of outer sleeve, and socket one belt on the above-mentioned driven gear, belt is socketed on the driving gear simultaneously, and described driving gear links to each other with the output of a motive power outputting apparatus.
The material that needs to grind enters grinding chamber from the charging aperture that is arranged on the feeding cylinder, and the drive lower millstone of rotating shaft rotates below mill, and the anterior thus roller that is stuck in the annular groove then rotates thereupon and carries out abrasive action.Simultaneously, be arranged on a plurality of fountain heads on the grinding chamber sidewall and ceaselessly spray water to the abrasive grains processing of lowering the temperature, and be arranged on air inlet on the grinding chamber sidewall ceaselessly to the grinding chamber air-supply, the material granule after the grinding is blown afloat from discharging opening discharges.For the material granule after the grinding is discharged equably from discharging opening, outer sleeve rotates under the drive of driven gear, driving gear and motive power outputting apparatus, can further drive lower house thus and rotate in the lump.The granularity of the particle after this vertical grinder grinds is little, even, flowable is good, thereby meets energy conservation and environment protection.And the spray cooling in process of lapping is handled can guarantee that the performance of abrasive grains is not destroyed.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, grinding chamber 1 is in the bottom of vertical grinder, and mill 2 is arranged in the bottom of grinding chamber 1, and the center below mill 2 connects a rotating shaft 3.Simultaneously, arrange that on the card of mill 2 one is the annular groove 4 at center with mill 2 axle center.One side of grinding chamber 1 is furnished with a roller 5, and the rear end and the frame of roller 5 are hinged, and the front portion cooperation of roller 5 is stuck in the annular groove 4.A plurality of fountain heads 6 are set on the sidewall of grinding chamber 1.Simultaneously, an air inlet 7 also is set on the sidewall of grinding chamber 1.
The top seal of grinding chamber 1 connects a lower house 8, and lower house 8 is provided with a cavity; The top seal of lower house 8 connects a upper shell 9, and upper shell 9 also is provided with a cavity, and, a discharging opening 10 is set on the sidewall of upper shell 9.
The upper end of feeding cylinder 11 is provided with charging aperture 12, and the lower end of feeding cylinder 11 and grinding chamber 1 are interconnected.Feeding cylinder 11 vertically places upper shell 9 and lower house 8, and is with outer sleeve 13 outside feeding cylinder 11.Described upper shell 9 and lower house 8 are arranged in the first half and the latter half of outer sleeve 13.And outer sleeve 13 is fixedlyed connected with lower house 8 by a plurality of dowels 14.The top of described outer sleeve 13 is connected with driven gear 15, and driven gear 15 is enclosed within outside the outer sleeve 13 fixedlys connected with described outer sleeve 13.Cover lace 16 on the above-mentioned driven gear 15, belt 16 is socketed on the driving gear 17 simultaneously.Driving gear 17 links to each other with the output of motive power outputting apparatus 18, and the motive power outputting apparatus 18 in the present embodiment can be a variable-speed motor.Motive power outputting apparatus 18 is connected on the frame.
