Abstract

The present invnetion relates to the field of solid material crushing equipment technology. During the crushing, the equipment can change its crushing mode with the change of material size to result in reasonable crushing mechanical characteristic, just as different teeth for different chewing function. The present invention can reach the goal of raising efficiency through "more crushing and less grinding" and integral crushing and grining. The combined double cone structure the milling cutter shaped inner upper cone and conic column with several homogeneously distributed concave surfaces in involute shape and having transverse wedged teeth. The upper cones complete crushing through relative motion and the lower cones complte grinding. In addition, the grinding body may be repaired for reuse for reuse and its concentric shaft structure is favorable to damping.

Description

Combined double cone pressure regulating crushing and grinding machine

The present invention is a solid material disintegrating apparatus technology, relates in particular to and a kind ofly utilize bending, extruding simultaneously, grinds, rubs multiple mechanical forces such as autogenous grinding, and material is efficiently pulverized, and realizes the incorporate technical field of broken mill.

Fragmentation is referred to as pulverizing with grinding, and its energy-efficient production technology is that numerous industrial fields are badly in need of.

Existing technical equipment, as gyratory crusher, jaw crusher, ball mill, rod mill, ring roll mill etc., their every kind of type majorities are finished fragmentation with single mechanical force or are ground, can not satisfy in crushing process, along with raw meal particle size changes and the change grinding mode, make and pulverize the mechanics characteristic tends in the reasonable optimizing designing requirement.Thereby exist efficient low, and operation is many, and equipment is huge, the noise height, the loss of mill body is big, and granularity is difficult to shortcomings such as control.

The purpose of the technical program provides a kind of, can will be by comminuting matter in the different grain size stage, accept different comparatively reasonably crushing forces respectively, with bionics principle:, take on different masticatory functions with different teeth.Improve crush efficiency greatly, realize " many broken few mills ", the incorporate equipment of broken mill.

For achieving the above object, the technical program is: by the combined double cone pressure regulating crushing and grinding machine that body, actuating unit, regulator, buffer unit, material-gathering device etc. are formed, bipyramid and the outer bipyramid mill of combination body in one group of combination that is installed on the concentric vertical pivot are arranged.

For ease of describing, division is as follows:

1, bipyramid, the outer bipyramid mill of combination body in the combination:

The technical program is: to be installed on the axle sleeve on the vertical pivot and to be connected to that bipyramid is a mantle in the combination on the axle sleeve, interior epicone is equivalent to the dog of traditional round conic crusher, and interior awl down is equivalent to movable grinding disc; The outer bipyramid of combination that is installed on the outer cone bearing is fixed awl, and outer epicone is equivalent to the mortar that rolls of traditional round conic crusher, the outer suitable fixed millstone of awl down.Inside and outside epicone is with material bending extruding force fragmentation, and inside and outside awl is down finished with the grinding power of rubbing and ground.The internal thread of interior epicone is connected with the interior external screw thread of awl down, and the external screw thread of outer epicone is connected with the outer internal thread of awl down, and with producing friction in its work and corresponding positive left-hand thread, lower cone firmly connects in the assurance.

For satisfying the inside and outside down taper thread grinding required concentric condition of work of material that minces, can make simultaneously the grating that under state without acceptance of persons, material fractureed of inside and outside epicone again, the interior epicone of this programme is a milling cutter shape, promptly makes two or more uniform recessed awl cylinders that axially is the involute shape on the awl post.On concentric shafts, two involute circular cone posts just form opposite 1/2 involute " off-centre " the awl post of both direction, in the time of three, form 1/3 involute " off-centre " the awl post of three directions, and the rest may be inferred by analogy.On recessed awl cylinder, be distributed with the side of outer epicone and bore the corresponding horizontal tooth of carving of transposition of teeth, make the material that falls into inside and outside epicone gap, blocked by the restriction of outer epicone tooth, the interior epicone that is rotated again horizontal carved the odontoclasis grating, falls into narrower interval, bottom and continues to pulverize.Finish material after the fragmentation by inside and outside epicone and enter inside and outside awl down automatically and grind, grinding is to be rubbed with the hands and the material autogenous grinding is finished by the intersection mill that is the radial roll flute in inclination angle.Because with the eccentric shaft of traditional round conic crusher, change into the opposite some/involute " off-centre " of several uniform directions, the specification requirement that had both solved broken mill one has also overcome the vibrations that the traditional round conic crusher causes because of off-centre effectively.

2, regulator:

The pressure regulation of this programme is to regulate inside and outside gap between the awl down, and control grinds granularity.It is by the corresponding up-down adjustment screw on top chock and the outer cone bearing, regulates that outer cone height finishes.Grind materials attenuates when requiring, or profile of tooth is repaired in the wearing and tearing back, former gap increases, when need replenishing, outer cone bearing bottom heightened the screw certain size that falls simultaneously, the downward modulation sieve silk on the bearing block of screwing on down, outer epicone pressurized, drive outer awl down and move down, the inside and outside gap smaller of awl is down adjusted, location, locking, downward modulation finish.Otherwise raise.

3, buffer unit:

When entering metal sundries for occurring overload or accident in preventing to grind, to the equipment buffer protection, this programme is equipped with the buffer unit that dish shape spring, buffing pad, thrust bearing are constituted in the inner cone axle sleeve lower end of vertical pivot.When above-mentioned situation occurring, interior stressed the moving down of awl down, and epicone moves down in driving, interior epicone drives inner cone axle sleeve compact disc shape spring by key and cushions.

4, material-gathering device:

This programme material-gathering device, be by the upper encloser that the selection by winnowing mouth is arranged that is installed in step centring ring upper surface, be installed in the pot shape aggregate bin that discharging opening is arranged of circle lower surface, step outer and be installed on circle in the interior awl down, the dust proof tube composition on the lower ball cover cylindrical.Three parts constitute the material-gathering device of good seal.When external blower fan was worked, fine powder fell into a pot shape aggregate bin from the selection by winnowing outlet sucking-off of upper encloser than Coarse Aggregate.Because the negative pressure that is formed by blower fan in the material-gathering device, the micronic dust during last feed hopper blanking also is inhaled into, and has prevented the charging dust pollution.

Below in conjunction with drawings and Examples this programme is further described.
