Description
Technical field
The utility model relates to a kind of grader, relates in particular to aim at the grader of calcining and grinding processing mica powder design.
Background technology
To be the natural mica material handle and obtain through calcining and grinding mica powder, and its shape is general to become irregular circle, and the diameter great majority are between 1-150 μ m.The employed method of present stage mica powder classification mainly is to adopt the principle of gravitational settling, make the mica powder back natural subsidence classification that stirs, and minority has the spiral shell sedimentation centrifuge for sleeping in that adopts Separation of Solid and Liquid to use to carry out classification.Its disengaging time of natural subsidence classification is long, production efficiency is low, and needs a large amount of log washers to carry out separating for several times, so the utilization of area rate is low, and how aging easily again required PVC log washer amount is.The spiral shell sedimentation centrifuge for sleeping in that minority adopts Separation of Solid and Liquid to use is non-also to need separating for several times just can obtain qualified product specially for mica powder designs, and its water consumption and power consumption are big, the production cost height.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of calcining and grinding of aiming at and handles the grader that the mica powder classification is used, and it needs first separation can obtain qualified products, and is energy-conservation and floor space is little.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: the centrifugal mica powder grader of a kind of spiral shell for sleeping in, comprise charging aperture, the solid phase outlet, the liquid phase outlet, rotary drum, screw feeder, distributing device, differential mechanism and transmission device, described rotary drum left part is provided with cylindrical circular rotary drum straight section, the rotary drum right part is provided with and is conical rotary drum awl section, the screw feeder that adapts with the rotary drum shape places in the rotary drum, the charging aperture that is positioned at the rotary drum left end is connected with the distributing device that lies in a horizontal plane in the rotary drum straight section, the liquid phase outlet is arranged at the left end of rotary drum straight section, the right-hand member bottom of rotary drum awl section is located in the solid phase outlet, the left end of rotary drum and screw feeder is supported by left shaft holder, the right-hand member of rotary drum and screw feeder connects by the right bearing seat supports and with differential mechanism, differential mechanism connects with transmission device, and the ratio of the rotary drum straight section internal diameter of the total length of described rotary drum and rotary drum is 2.5-2.80: 1.Be preferably 2.65-2.70: 1.The tapering of described rotary drum awl section is preferably the 8.8-9.0 degree.
The beneficial effects of the utility model are: the centrifugal mica powder grader of spiral shell for sleeping in of employing such scheme can disposablely be isolated the mica powder of 2-75 μ m, required time is short, energy-conservation, power consumption and water consumption are low, and lower than the cost of PVC log washer staging, and physical life is long, floor space is little.Because replaced manually-operated with mechanization production, avoided artificial difference, parameter control is stable, and the end product quality of resulting mica powder is stable, and required time is short and good with the connectivity of next procedure.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
As shown in the figure, a kind of embodiment of the centrifugal mica powder grader of spiral shell for sleeping in, comprise charging aperture 2, solid phase outlet 4, liquid phase outlet 5, rotary drum 1, screw feeder 6, distributing device 7, differential mechanism 8 and transmission device, described rotary drum 1 left part is provided with cylindrical circular rotary drum straight section 1a, rotary drum 1 right part is provided with and is conical rotary drum awl section 1b, the screw feeder 6 that adapts with rotary drum 1 shape places in the rotary drum, the charging aperture 2 that is positioned at rotary drum 1 left end is connected with the distributing device 7 that lies in a horizontal plane in rotary drum straight section 1a, liquid phase outlet 5 is arranged at the left end of rotary drum straight section 1a, the right-hand member bottom of rotary drum awl section 1b is located in solid phase outlet 4, the left end of rotary drum 1 and screw feeder 6 is supported by left shaft holder 3, the right-hand member of rotary drum 1 and screw feeder 6 is supported by right bearing seat 9 and connects with differential mechanism 8, differential mechanism 8 connects with motor by transmission device, in order to obtain the mica powder of 2-75 μ m, the ratio of the rotary drum straight section internal diameter of the total length of described rotary drum 1 and rotary drum 1 is 2.5-2.80: 1; The tapering of rotary drum awl section is the 8.8-9.0 degree.Because if the ratio of the rotary drum straight section internal diameter of the total length of rotary drum 1 and rotary drum 1 is excessive, then having the undesirable small particle diameter mica powder of part sneaks in the solid phase finished product, cause finished product defective (particle diameter is thin partially) and need separate once more, thereby increased specific energy consumption; If the ratio of the rotary drum straight section internal diameter of the total length of rotary drum 1 and rotary drum 1 is too small, then have the mica powder that partly meets the finished product grain size requirement and enter down road classification operation from liquid phase, making the solid phase finished product grain size partially slightly need return again separates, and the mica powder upper limit of road separation circuit partially slightly can not be used under causing, and has equally also increased specific energy consumption.The excessive big particle diameter mica powder of part that then has of the tapering of rotary drum awl section enters down the road separation circuit; The too small part small particle diameter mica powder that then has of tapering of rotary drum awl section enters the finished product from solid phase.The ratio of the rotary drum straight section internal diameter of the total length of present embodiment rotary drum 1 and rotary drum 1 is 2.68: 1, and tapering is 8.9.And adopt bi-motor frequency conversion, the grading effect that makes to reach best.Adopt the benefit of bi-motor frequency conversion to be: two motors all adopt the mode of common bus to control by frequency converter, can not only realize that energy is shared, and can adjust the difference rotating speed effectively, timely, guarantee the grading effect that grader is stable
Its principle is in the rotary drum that rotates at a high speed screw feeder 6 to be housed, and the direction of rotation of screw feeder 6 is identical with rotary drum, but produces certain speed difference by differential mechanism 8 between the two.Mica powder suspension to be fractionated enters in the machine from charging aperture 2, and under action of centrifugal force, the solid phase finished product is deposited in drum inner wall, is pushed to rotary drum awl section 1b by screw feeder 6, discharges from solid phase outlet 4; Flow out from rotary drum straight section 1a liquid phase outlet 5 liquid phase clarification back.
