Abstract
The utility model discloses a forcing arm mounting mechanism, which is used for mounting a forcing arm of the vertical grinder, and comprises a forcing arm, a mandrel, a supporting seat and a positioning pin. One of the forcing arm and a roller carrier is provided with a notch while the other extends into the notch, the mandrel is transversely inserted on the forcing arm and the roller carrier, two extending ends of the mandrel are respectively supported on the supporting seat, and a distance is pre-reserved between the mandrel and the positioning pin which is inserted on the forcing arm and the roller carrier. When grinding rollers are overturned to the outside of a shell of the grinder, only the positioning pin needs to be detached, and thereby detachment time is less and labor intensity for operation is low. The forcing arm exerting force on the roller carrier from the middle enables the roller carrier to be even in bearing, so that the grinding rollers are stable in operation. By the aid of the forcing arm exerting force on the roller carrier from the middle, the forcing arm and the roller carrier can be connected and fixed quite compactly, and accordingly, swing distance of the grinding rollers is large, the grinding rollers in operation are capable of safely avoiding oversize mixed iron or particles, and accidental damage of equipment is avoided.
Description
Technical field
The utility model relates to the vertical grinder technical field, particularly a kind of vertical grinder and arm installing mechanism thereof.
Background technology
Vertical grinder is suitable for grinding and pulverizing various materials; The raw meal particle size that utilizes vertical grinder to grind is even, particle is trickle; Vertical grinder also can mix several kinds of materials extremely uniformly, is widely used in cement, industrial chemicals, abrasive material, pottery, ore, coal dust, metal dust, magnetic material etc.Because the nonferromagnetic substance that vertical grinder is unique has in industry obtained using widely.
As depicted in figs. 1 and 2; Present vertical grinder comprises housing 102, cover plate 118, drive unit 101 and the vertical mill tube 103 and the grinding roller 106 that are driven by this drive unit 101, the arm 108 that acts on grinding roller 106, and this arm 108 provides pressure by oil cylinder 109.The flour milling of the roll surface of grinding roller 106 and vertical mill tube liner constitutes break-in face, also is provided with screeding device 105, and material gets into vertical mill tube 103 through charging aperture 107; Drive unit 101 drives vertical mill tube 103 and rotates; Grinding roller 106 rotations are ground the material that gets into break-in face, and 105 pairs of polished materials of screeding device loosen, water conservancy diversion; After grinding, discharge vertical mill tube; Pressure air is got into by air inlet 111, and fine powder is discharged by outlet 112 through sorter 104, and coarse grain, foreign material are then by outside the discharging opening 110 discharge machines.When material after charging aperture gets into vertical mill tube, the thickness material after grinding roller 106 grinds is discharged vertical mill tube, this grinding machine bottom does not have pressure air to get into, the thickness powder after grinding is all outside the discharging opening discharge machine of grinding machine bottom.
The mounting structure of grinding roller 106 generally is made up of the mode of Fig. 2 and Fig. 3 at present, promptly also can let the supporting base 116 of its swing constitute with arm 108 by roller frame 114 and coupled transverse axis 117.Roller frame 114 is fixedly connected with the roll shaft 113 of grinding roller 106; Arm 108 is connected through mandrel 115 with transverse axis 117 with roller frame 114; Mandrel 115 is provided with respectively the key that cooperates with arm 108 and keyway on the transverse axis 117; To prevent the rotation between arm 108 and the roller frame 114, this arm 108 provides pressure by oil cylinder 109.Arm 108 is offset to a side of transverse axis 117 usually, and promptly supporting base 116 is between arm 108 and transverse axis 117.
The deficiency that the mounting structure of existing arm 108 exists is:
Inconvenient and the length consuming time of dismounting owing to adopting key to connect, therefore when dismounting transverse axis 117 and roller frame 114, must could be accomplished the dismounting between transverse axis 117 and the arm 108 at first with oil cylinder 109 dismountings;
It is big to take up room behind arm biasing one side; Make entire machine design be not easy to arrange; The hunting range that also causes arm is limited and cause running into excessive assorted iron or the bed of material when too thick; Possibly make arm stuck and damage grinding roller and cause equipment breakdown, the arm mandrel one end pressurization of only setovering, also can make arm and mandrel monolateral stressed cause moving not steady.
