Detailed description of the invention
With reference to accompanying drawing, the utility model horizontal decanter centrifuge spiral stock pusher abrasion-proof structure embodiment is described further.
A kind of horizontal decanter centrifuge spiral stock pusher abrasion-proof structure, comprise rotating cylinder 1 and the helical blade 2 affixed with rotating cylinder 1, helical blade 2 comprises working face and non-working surface, working face is detachably fixedly connected with wearproof structural tier, wearproof structural tier is wearing plate 3, the side of wearing plate 3 abuts with helical blade 2, fixation kit is provided with between wearing plate 3 and rotating cylinder 1, wearing plate 3 is connected by fixation kit with rotating cylinder 1, by the wearing plate 3 be detachably fixedly connected with, wearing plate 3 is changed after can using a period of time, thus ensure that helical blade 2 is not easy to wear and tear, wearing plate 3 is connected with rotating cylinder 1 by fixation kit simultaneously, helical blade 2 overall structure can not be destroyed like this, ensure the structural strength of helical blade 2, the side of certain wearing plate 3 fully abuts with helical blade 2, what make that the power suffered by wearing plate 3 can be full and uniform passes to helical blade 2, make helical blade 2 can not local pressure excessive and cause damage, thus ensure that the service life of helical blade 2.
As preferably, fixation kit comprises flanging 31, and flanging 31 and wearing plate 3 can be one-body molded, flanging 31 is arranged the through hole run through for bolt 4, affixed by bolt 4 between flanging 31 and rotating cylinder 1, such to arrange structure comparatively simple, processing is got up more for convenience, with low cost.Flanging 31 abuts with rotating cylinder 1 and arranges simultaneously, can ensure the stability that wearing plate 3 connects, can be fixed by multiple bolt 4, can ensure the fastness that wearing plate 3 is fixing so further.
Wearing plate 3 away from rotating cylinder 1 side to rotating vane curving formed flange 32, to be used in the side of helical blade 2 flange 32 push solid-phase material, flange 32 is that the arc surface of flange 32 contacts with solid-phase material when contacting with solid-phase material, when arc surface is subject to the power from solid-phase material, can power be carried out dispersed, make power vertically less, ensure that bending damage is less likely to occur helical blade 2.
Accurately can locate in order to wearing plate 3 and fix more firm, flange 32 is outwardly near helical blade 2 side is formed with the gulde edge 7 abutted with non-working surface, when installing wearing plate 3, helical blade 2 is clamped by gulde edge 7 and flange 32, make wearing plate 3 be less likely to occur to rock, thus ensure the stability that wearing plate 3 is connected with helical blade 2.As preferably, be formed with fillet structure 6 between gulde edge 7 and flange 32, such arranging ensures and carrys out the structural strength of gulde edge 7, ensures that gulde edge 7 is less likely to occur time stressed to damage.Further, the opposite side that gulde edge 7 is fixing with flange 32 is provided with lead-in curve 71.When helical blade 2 inserts between gulde edge 7 and flange 32, lead-in curve 71 can play certain guiding function, during insertion, helical blade 2 can first abut with lead-in curve 71, then slide along lead-in curve 71, thus complete location, be less likely to occur the phenomenon blocked during such location, ensure that the efficient and convenient of installation.
In order to strengthen the structural strength of helical blade 2 further, reinforcement 5 can be connected with between non-working surface and rotating cylinder 1, reinforcement 5 can be made of one piece, make helical blade 2 to play good supporting role when being subject to the power from working face by reinforcement 5, thus ensure that bending damage is less likely to occur helical blade 2.As preferably, the surface of reinforcement 5 is circular arc, and such structure can be more effective by suffered stress dispersion, thus further ensure the structural strength of helical blade 2, ensure that the service life of helical blade 2.
Helical blade 2 is arranged to wearing plate 3 lopsidedness, by such setting, can provide component to rotating cylinder 1 to a certain extent for wearing plate 3, make wearing plate 3 be not easy to depart from, ensure that the stability that wearing plate 3 is affixed.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
