Description
Technical field:
The utility model relates to the machinery that a kind of element of milling of using roller and ring or dish teamwork is pulverized, be specifically related to the floating annular grinder that grinds.
Background technology:
Equipment ubiquities such as existing pulverizer apparatus such as ball milling, rod milling that efficient is low, energy consumption is high, the wearing detail consumption is big and safeguard problem such as dismounting and change difficulty; Though having appearred in the seventies, a kind of centrifugal hoop grinding machine can enhance productivity, cut down the consumption of energy, but owing to existing feed preparation unit size strict (must less than 25mm), traction to grind the easily broken and feed maldistribution of the bearing pin of ring and the big defectives such as (105dB) of operating noise fails to be extensive use of in industry.In order to address the above problem, inventor of the present utility model developed a kind of flour mill of knowing clearly again in last year, as patent announcement number 2485039 disclosed a kind of " floating stone roller formula flour mills ", it has the feed hopper of a band angle of repose and is enclosed within the mill that rotates on the main shaft, several cambered surface grooves are arranged at the mill edge, place a cake and and the interactional mill lining of cake on each cambered surface groove.Though this structure can solve the high problem of energy consumption, but the groove direct friction of this abrasive body and liner plate is is easily worn and torn, will wholely change after several days, supporting between cake and mill is also short service life, the mechanical strength of liner plate is also less simultaneously, easily smash, the plant maintenance manufacturing cost is all higher; In addition, the swing of said structure complete machine is bigger, and operating noise is still bigger, so the user reflects that suggestion has stopped having produced greatly after using a period of time.
Summary of the invention:
Task of the present utility model is to provide that a kind of mechanical strength that can solve the liner plate in the grinding device is little, cost is high, the life-span is short, the floating stone roller annular grinder of, problem such as operating noise big strict to feed preparation unit size, in the time of simultaneously can also realizing plant maintenance, chassis door be can directly open easily and wearing detail, the purpose of good energy-conserving effect changed.
To achieve these goals, a kind of floating stone roller annular grinder that the utility model proposes, by support, casing, feed arrangement, drawing mechanism, grinding device and transmission device constitute, casing be positioned at support above, casing is one and has with gemel hinged door cylinder, the top of casing is provided with feed arrangement and transmission device, belt driver is by motor, the universal joint shaft joint, bevel gear gearbox and transmission main shaft constitute, the motor level is placed on the base, and the output main shaft of motor connects the universal joint shaft joint by the middle transition case, the transmission main shaft that encircles in the mill apparatus given transmission of power by the bevel gear gearbox.The below of support is a drawing mechanism, the ring mill apparatus is positioned at the inside of casing, core grinding and stacked lining have been comprised, core grinding in the ring mill apparatus is by mutual coaxial overlapping the combining of rotating disk of floating muller with the band more than two, a transmission main shaft passes the axis centre of core grinding, the rotating disk of the floating muller of this band is the stratiform disk body of a section for " soil " or " master " font, the stratiform extension of rotating disk is the dish wing, its edge of a wing is all downward-sloping certain angle of one side up, a uppermost rotary case is " soil " font, its top is also folded to have one to be conical equal charging tray, in every disk body between the adjacent two layers dish wing and in the space between per two rotating disk adjacent two layers dish wings, with the spindle axis is that symmetric points are equipped with three to ten floating mullers symmetrically, the top and bottom of floating muller all are lined with the wear-resisting tray plate that is linked to be ring-type with coiling between the edge of a wing, and this wear-resisting tray plate is the loop shaped that is joined by two or more than two partial arc plate.The dish flank that leans on rotating disk between the adjacent floating muller slightly also is the push and block wheel that symmetric points are equipped with respective numbers symmetrically with the spindle axis, in each push and block wheel bearing is housed, on the dish wing position of the plate of tray up and down of push and block wheel bearing hole site, rotating disk, all have and dead eye through hole of a size, the position, hole of these through holes each interlayer when the mutually coaxial overlapping combination of rotating disk communicates, and each Kong Weijun is inserted with the bearing pin of a two ends band screw mandrel; Stacked lining in the ring mill apparatus is to grind ring by polylith, the mutual up and down stacked composition of gasket ring, the superiors' lining is a crushable layer, ring stone roller road was divided into two parts up and down with this inwall in inner wall surface thereof had together, two-part inwall axially has trapezoidal groove more than five again equably up and down, the cross section of lining second layer ring-type liner plate is L-shaped, right angle, liner plate bottom has the sieve groove to constitute annular sieve plate on the outstanding limit, the 3rd layer and the ring-type liner plate more than three layers are for grinding ring, the floating muller that the inwall of stone roller ring has constituted in the corresponding core grinding grinds the road, folder is lined with gasket ring cylindraceous between the second layer and the stone roller ring more than the 3rd layer and the 3rd layer, and the inwall that the inwall of this gasket ring grinds ring relatively is low.Also be lined with shakeproof layer between stacked lining in the ring mill apparatus and the casing.
Because casing of the present utility model is designed to one and has with gemel hinged door cylinder, can directly open chassis door and change wearing detail, so plant maintenance is convenient.The utility model all is lined with wear-resisting tray plate between the top and bottom of floating muller and the dish edge of a wing; the dish flank that leans on rotating disk between the adjacent floating muller slightly is that symmetric points are equipped with the push and block wheel symmetrically with the spindle axis; in each push and block wheel bearing is housed again; protected the wearing and tearing of floating muller on core grinding like this, compared with prior art and can prolong 3 times of floating muller service lifes.Stacked lining in the utility model ring mill apparatus is used polylith instead and is ground ring, the mutual up and down stacked composition of gasket ring, the inwall that the inwall of this gasket ring grinds ring relatively is low, all each layers all are that the stone roller ring serves as stone roller road and the floating muller interaction of corresponding each layer, processing can be saved the higher liner plate materials of cost like this, can reduce equipment cost 60%, and stress in use can not take place concentrate and to cause the fracture of monoblock liner plate, thereby the problem that the mechanical strength that has solved the liner plate in the existing grinding device is little, the life-span is short.In addition the utility model ring in the mill apparatus stacked lining and casing between also be lined with shakeproof layer, can solve the big problem of operating noise, the actual measurement noise is 88dB, motor level in the transmission device of casing top laid overcome the bigger defective of prior art complete machine swing, therefore the utility model will be the desirable first-selected product that existing size reduction machinery updates, and market prospects are boundless.
