Abstract
The utility model is double layers, four rollers, and second grade pulverizer of anticentripetal negative pressure, which comprises an engine base, a body case, a feed hopper, an out-feed hopper,a powder apparatus and a gearing apparatus. The powder apparatus is arranged in the body case, which is composed of an abrasive roller and an abrasive circle. The abrasive circle is arranged on the engine base, wherein the abrasive base of two layers coaxial linkage is arranged. The outside of each layer abrasive base is provided with two symmetrical abrasive rollers whose axial centers are arranged straightly. The surface of the abrasive roller is fixed with the inner face of the abrasive circle, which can reduce the powder pollution in the process of abrasion. Compared with the equipment of ball grinder, the utility model has the advantage of less noise, low cost and good grinding effect.
Description
Affiliated technical field
The utility model relates to a kind of grinding machine, is specifically related to particulate material is milled into the roller type flour mill of powdered substance.
Background technology
Industrial grinding machine commonly used has ball mill, garden disc type grinding machine, Raymond mill etc., and efficient is low, steel consumption is big, manufacturing cost is high, the wearing detail consumption is big but above-mentioned pulverizer apparatus ubiquity, and safeguards problems such as dismounting and change difficulty.
Summary of the invention
The utility model will design a kind of relatively simple for structure exactly, uses and keeps in repair more conveniently, and dust seal is effective, the centrifugal negative pressure double layer four roller two grade powder grinder of efficient energy-saving.
The technical scheme that its technical problem that solves the utility model adopts is: the centrifugal negative pressure double layer four roller two grade powder grinder of design, by support, casing, charging aperture, discharging opening, grinding device and transmission device constitute, casing be positioned at support above, casing is a cylinder, grinding device is positioned at the inside of casing, grinding device is made up of mixing roll and grinding ring, grinding ring is contained on the support, be provided with the grinding chassis of two-layer coaxial interlock in the grinding ring, every layer is ground two mixing rolls that the chassis periphery is provided with symmetry, vertically place in the mixing roll axle center, and mixing roll roll surface and grinding ring inner face are fitted.The axle of drive motors passes support and is connected with the axle sleeve that grinds the chassis, be provided with radial vertical material baffle between the two-layer grinding chassis, charging aperture passes casing and upper strata grinding center chassis leads to lower floor's grinding center chassis, discharging opening is positioned at pyramid type loading head top, casing top, in the casing through the discharging opening formation negative pressure of outwards bleeding.The diameter of upper strata mixing roll and height are less than lower floor's mixing roll, and the last lower shaft end of each roller is equipped with bearing, and lower floor grinds below the chassis and between the support roller is housed.The roller place is installed on the two-layer grinding chassis journal bearing slideway is housed, roller bearing is installed in can be in the slideway that certain limit moves radially.When driven by motor was ground the chassis rotation, mixing roll was under centrifugal action, and roll surface is pasting grinding ring and rolling.
The utility model is simple in structure, is the cavity of a sealing in the flour mill, and the material that enters from charging aperture grinds through two-layer mixing roll, when reaching certain fineness, under the effect of negative pressure from the discharging opening sucking-off and collect.Can reduce the dust pollution of grinding process.Compare the equipment of ball mill class, noise is little, energy consumption is low, and the effect of grinding is even more ideal.
Description of drawings
Fig. 1 is an overall structure principle schematic of the present utility model.
Fig. 2 is the generalized section of the utility model material baffle, roller part.
The specific embodiment
Centrifugal negative pressure double layer four roller two grade powder grinder, by support 1, casing 14, charging aperture 13, discharging opening 16, grinding device and transmission device constitute, casing 14 be positioned at support 1 above, casing 14 is a cylinder, grinding device is positioned at the inside of casing 14, grinding device is by mixing roll 9,10 and grinding ring 8 form, grinding ring 8 is contained on the support 1, be provided with the grinding chassis 3 of two-layer coaxial interlock in the grinding ring 8,12, every layer is ground two mixing rolls 9 that the chassis periphery is provided with symmetry, 10, mixing roll 9, vertically place in 10 axle center, mixing roll 9,10 roll surfaces and grinding ring 8 inner faces are fitted.The axle of drive motors 2 passes support 1 and is connected with the axle sleeve 5 that grinds chassis 3,12, be provided with radial vertical material baffle 4 between the two-layer grinding chassis 3,12, charging aperture 13 passes casing 14 and grinding 12 centers, chassis, upper strata are led to above lower floor grinding 3 centers, chassis, and charging aperture 13 grinds junction, 12 center, chassis with the upper strata sealing gasket 11 is housed.Discharging opening 16 is positioned at pyramid type loading head top, casing 14 top, and venetian blind type shelves flitch 15 is housed in the pyramid type loading head, can prevent that granule materials from spilling.In the casing 14 through the discharging opening 16 formation negative pressure of outwards bleeding.The diameter of upper strata mixing roll 10 and height are less than lower floor's mixing roll 9, and the last lower shaft end of each roller is equipped with bearing 7, and lower floor grinds below the chassis 3 and between the support 1 roller is housed. Roller 9,10 places are installed on the two-layer grinding chassis 3,12 journal bearing slideway 6 is housed, roller bearing 7 is installed in can be in the slideway 6 that certain limit moves radially.Motor 2 drives when grinding chassis 3,12 rotations, and mixing roll 9,10 is under centrifugal action, and roll surface is pasting grinding ring 8 and rolling.Be the cavity of a sealing in the flour mill, the material that enters from charging aperture 13 grinds through two-layer mixing roll, when reaching certain fineness, under the effect of negative pressure from discharging opening 16 sucking-offs and collect.
