Abstract
The utility model relates to a novel high pressure hangs grinding roller has a casing, and the grinding roller is installed on the centre frame, hangs axle and grinding roller and rotates around the center pin, and the rotation again leans on centrifugal force and spring force to smash the material simultaneously, and tension spring hangs on the center-support, couples on the suspension roller arm of force through cone nut and Y-shaped mechanism. One end of the tension spring is of a conical structure, the conical nut is installed inside the tension spring, and the force arm of the rotary roller is connected to the top of the shell of the rotary roller assembly through the bolt. The utility model has the advantages that: simple structure, reasonable in design, this overhang roll grinding apparatus have the characteristics that the crocus is efficient, operate steadily, have improved discharge mechanism simultaneously, can go out several kinds of different materials simultaneously.
Description
The utility model relates to a kind of material to be pulverized and lapping device, and particularly common overhang roll mill is by action of centrifugal force material to be pulverized and ground.Pulverization principle proves: material grinding efficient is directly proportional with normal pressure, so strengthen the pressure of overhang roll the efficient that improves flour mill is had important relationship.Existing high pressure overhang roll mill is to utilize the pressure of compression spring to act on the assembly arm of force that overhang roll assembly top, horizontal draws, and its effect affacts on the assembly arm of force by bearing support vertically downward.Because the assembly arm of force is limited by mill structure, length is very short, and promptly power arm is short, the resistance brachium.Because its several arm of force and same bearing support effect, the impact generation that roller is subjected to bulk materials when grinding machine work rebounds.Have influence on the operate as normal of other grinding roller by bearing support.
The purpose of this utility model is to provide a kind of novel high-pressure to revolve the roller mill, adopt the mode of extension spring active force to put on separately on each overhang roll, avoid several rollers to influence each other at work, and the pulling force that each spring produces all is a horizontal direction, can not produce big axial force, to simplify main shaft portion
The novel high-pressure overhang roll grinding tool of the utility model design has a casing (1), the grinding roller (8) that three or four rotations are wherein arranged, grinding roller is installed on the centre frame (10) that is driven by central shaft (11), outstanding axle (9) and grinding roller (8) rotate around central shaft (11), rotation is again simultaneously pulverized material by centrifugal force and spring force, and characteristics of the present utility model are, tension spring (2) is hung on the center support (5), is connected on the overhang roll arm of force (6) by tapered cup nut (3) and furcated mechanism (4).Described tension spring (2) one ends are pyramidal structure, and tapered cup nut (3) is installed on tension spring (2) inside, revolve the roller arm of force (6) and are connected in by bolt and revolve roller assembly shell (12) top.
When the powder process of some industry, promptly need fines to need coarse fodder again, at this needs, the utility model has discharging opening (7) on casing (1), and the material that perching knife has flown upward is located to flow out at discharging opening (7).The optimum position of this discharging opening is arranged on apart from bull ring (13) and goes up the 150-350 millimeter place that makes progress, plane, and is provided with the screen cloth (17) of an interconvertible band gradient at the discharging opening place, can change screen cloth (17) according to different needs.
The structure that the novel high-pressure overhang roll that the utility model is provided below by accompanying drawing grinds is described further.
Accompanying drawing: the utility model structural representation.
The outstanding axle of 1-casing 2-tension spring 3-tapered cup nut 4-furcated mechanism 5-centre bearing 6-overhang roll arm of force 7-screen cloth 8-grinding roller 9-10-centre frame 11-central shaft 12-shell 13-bull ring 14-pin 15-pin 16-nut 17-screen cloth
The operation principle of the utility model high pressure overhang roll mill is identical with common overhang roll mill, material adds from charging aperture to be fallen on the perching knife, by perching knife material is scooped up, and the material that is scooped up drops between bull ring and the grinding roller, grinding pressure by grinding roller is pulverized the material fragmentation.Novel high-pressure overhang roll mill is to be hung in the centre bearing (5) by tension spring (2), is connected on the overhang roll arm of force (6) by tapered cup nut (2) and furcated mechanism (4), regulates tapered cup nut and makes spring produce pulling force, sets up the back and is fixed with nut (16).The pulling force of spring is towards central shaft, and the fulcrum of lever is pin (14), and grinding roller is stressed towards bull ring (13).In order to reduce the centrifugal reaction force of pin (14) with top, the overhang roll arm of force (6) adopts lightweight construction.Overhang roll arm of force material can be made with hollow profile or the little composite of density.
The utility model has the advantages that: simple in structure, reasonable in design, overhang roll Mill is applied on the overhang roll by the overhang roll arm of force by the pulling force of spring, because its power Arm is vertically upward, and the power arm that not can do by the restriction of structure is longer And be associated with a tension spring, each overhang roll on each overhang roll arm of force Spring all works independently, and has so just avoided several rollers at work Influence each other. The pulling force that each spring produces is horizontal direction, can not Produce big axial force, to simplify the design of main shaft part. This overhang roll grinding tool The characteristics of abrasive dust efficient height, smooth running are arranged, improved simultaneously discharging mechanism , can go out simultaneously several different materials.
