Description

Novel hydraulic-control vertical disc roller flour mill

Technical field

The utility model relates to a kind of abrasive dust mechanical device, especially adapts to the contour meticulous abrasive dust hard or sticking, softer material of metallic ore or nonmetallic ore and processes.

Background technology

Flour mill commonly used at present is ball mill or Raymond mill.Ball mill is to utilize the collision ground material between a plurality of steel balls in the cylinder, so idle work is many, energy consumption is big, efficient is low; Raymond mill is the centrifugal force extruding comminuting matter by bistrique, and the grinding machine body is produced bigger rigid shock, has the shortcoming that energy consumption is big, noise is big, the life-span is low, yield poorly.Because also existing many problems and be difficult to, the restriction of structure and operation principle, above-mentioned two kinds of grinding machines solve, thus the development of new flour mill consistent problem of being concerned about that is numerous producers.

The utility model content

The purpose of this utility model is to provide a kind of effect height, powder delivery is thin, the life-span is long novel hydraulic-control vertical disc roller flour mill.

To achieve these goals, the utility model adopts following technical scheme: a kind of novel hydraulic-control vertical disc roller flour mill, what comprise that rotating wedge shape peviform mill and three cooperate with the mill madial wall is arranged on grinding roller on the bistrique, bistrique is hinged by rocking arm and body, mill and grinding roller all are connected with the independent power source that drives in the same way, have speed difference therebetween; Be provided with the screw mandrel adjusting device that to regulate gap between mill and the grinding roller between mill and the grinding roller.

Described rocking arm top is affixed with bistrique by pin and four taper pins; the earrings on rocking arm lower end and the lower body is hinged; be provided with the adjusting leading screw hinged with body, the sheathed adjusting nut in leading screw outer end in the rocking arm interstitial hole, and rocking arm inboard elasticity abuts against the oil cylinder piston outer end of being fixed in outside the upper machine body; Mill roller motor is installed in the rocking arm upper outside.

Described upper machine body three oil cylinders outside and that act on respectively on three rocking arms that are arranged on link to each other with Hydraulic Station by a flexible pipe respectively, are connected with pressure switch, accumulator and solenoid directional control valve on the Hydraulic Station oil circuit.

(1) extruding force between mill and grinding roller is controlled by the hydraulic pressure system system, load amplitude and can regulate (maximum load power reaches 15 tons) arbitrarily with the material properties difference, grinding machine capacity usage ratio height (2) mill and grinding roller by separately independently power source drive in the same way, there is the speed difference (difference is adjustable) that configures therebetween, material is had strong extruding, shearing, pulverization, improved fine powder rate and discharging fineness; (3) material that enters in the mill enters the wedge shape crushing chamber under action of centrifugal force, increased the material size scope (0.5mm-20mm) of grinding machine processing: (4) grinding roller loads motion by HYDRAULIC CONTROL SYSTEM, impact shock when making complete machine stable working, comminuting matter is little, noise is low, has prolonged organism life-span; (5) minimum clearance of department's wedge shape working chamber of mill and emery wheel can be regulated by regulating screw mandrel according to the concrete condition of pan feeding and discharging, helps satisfying the abrasive dust processing of various thing section.

The beneficial effects of the utility model are: this machine is applicable to the material that is manufactured into material granularity wider range, energy consumption than present grinding machine commonly used is low, output big, fine powder rate and fineness height, the complete machine oscillation noise is little, the life-span is long, can be used as the renewal product of flour mill.

The specific embodiment

Embodiment: novel hydraulic-control vertical disc roller flour mill as shown in Figure 1, what comprise that rotating wedge shape peviform mill 12 and three cooperate with mill 12 madial walls is arranged on grinding roller 5 on the bistrique 9, bistrique 9 is hinged by Rocker arm 4 and lower body 13, mill 12 and grinding roller 5 all are connected with the independent power source that drives in the same way, have speed difference therebetween; Be provided with the screw mandrel adjusting device that to regulate gap between mill 12 and the grinding roller 5 between mill 12 and the grinding roller 5.

Rocker arm 4 top is affixed by pin and four taper pins and bistrique 9, grinding roller 5 is arranged on the front end of bistrique 9, the rear end of bistrique 9 connects the adjustable frames of Rocker arm 4 upper end; the earrings on Rocker arm 4 lower end and the lower body 13 is hinged; the Rocker arm 4 interstitial hole inserts adjusting screw mandrel 6, a leading screw outer end sheathed adjusting nut hinged with body, and the inboard elasticity of Rocker arm 4 abuts against the oil cylinder piston outer end of being fixed in upper machine body 10 outsides; Mill 12 and grinding roller 5 are connected by belt transmission by motor 1,7 separately.

Be arranged on upper machine body 10 three one-way cylinders 201 outside and that act on respectively on three Rocker arm 4s and link to each other with Hydraulic Station by a flexible pipe 202 respectively, be connected with pressure switch 203, accumulator 204, solenoid directional control valve 206 and hand-operated direction valve 205 on the Hydraulic Station oil circuit.

Mill 12 is arranged on the Upright post base 3, mill 12 is by engine reduced power device 2 driven rotary; the power bistrique 9 that Rocker arm 4 supports inserts in the mills 12; turning to by motor 7 of grinding roller 5 drives; turning to by motor 1 of mill 12 drives, on the bistrique 9 grinding roller 5 turn to consistently with turning to of mill 12, and keep certain speed difference; mill 12 and grinding roller 5 mutual group wedgewise crushing chambers, the minimum clearance in this chamber is regulated and is determined by regulating screw mandrel 6.The required maximum load power of comminuting matter is to pass to grinding roller 5 by load cylinder (one-way cylinder) 8 that acts on the Rocker arm 4 by bistrique 9, and the amplitude of power is by HYDRAULIC CONTROL SYSTEM, and the one-way cylinder hydraulic system is connected with Hydraulic Station 14.During abrasive dust, material enters mill 12 centers from the feed pipe 11 of upper machine body 10 sides, and with mill 12 rotations, under action of centrifugal force, material slides to the wedge shape crushing chamber at place, mill 12 outers, is pulverized under strong extruding, shearing, pulverization.Air stream enters in the machine from lower body 13, swirling eddy upwards flows from mill 12 bottoms, and the material that drives the certain fineness requirement enters upper machine body 10 and continues and upwards enters grading plant, is collected as finished product, the material of backlog demand returns in the mill 12 along upper machine body 10 inwalls, and is levigate again.
