Abstract
The utility model relates to a novel all-push feeding machine for grinders, which solves the problems that in the traditional grinder feeding device, the structure is complex, the leakage exists and the filling rate of the cylinder body is low. The novel all-push feeding machine for grinders comprises a rotary type external cylinder (5) and a central shaft (7) positioned in the external cylinder (5) and coaxial with the external cylinder (5), wherein, a plurality of spirals (3) are fixedly connected on the inner wall of the external cylinder (5) (the quantity of the spirals is supposed as n, and the angle of spiral angle is supposed as B), and nB is larger than or equals to 360 DEG C; the bottom part of the spirals (3) are fixedly connected to the inner wall of the external cylinder (5), and the outer circular surface of the central shaft (7) is fixedly connected to the top parts of the spirals (3). The grinder all-push feeding machine has the advantages that the filling rate of the cylinder body of the grinder can be greatly increased, thus the leakage of the cylinder body is not generated, and the energy consumption can be reduced.
Description
Technical field
The utility model relates to a kind of feed appliance of giving of grinding machine.
Background technology
Grinding machine is to be used for crucial plant equipment that material is pulverized on the industrial production.Be divided into autogenous tumbling mill, pebble plain, half from (ball) grinding machine and rod mill by the abrasive material kind; Be divided into wet type and dry type by the material form; Be divided into lattice type and overflow type again by the discharge situation.Various grinding machines constitute by feed portion, feeder, barrel, discharging portion, base bearing portion and driving section.Now be made up of funnel, heavy associating (cydariform) dispenser down with most of mill feed portion, feeder is made up of charging end cap, charging liner plate and charging aperture (basin).Abrasive material and material enter associating (cydariform) dispenser from following funnel, rise to centre bore by spiral and send into charging aperture (basin).They are pushed in the cylindrical shell by the feeding screw in slide or the charging aperture under the charging basin conical surface.Some is also without dispenser, and abrasive material and material are directly sent into charging basin (mouth) by feed pipe (funnel).The inner conical surface of charging basin does not have feeding screw.As shown in Figure 1
3.6 * 6m overflow ball mill, steel ball, ore and water are slipped into charging aperture through feed pipe by following funnel, are pushed into cylindrical shell by the charging aperture spiral again.Mix dynamic pack completeness when being 29% when reality, ore pulp just returns charging aperture by the charging aperture screw top in the cylindrical shell; Actual mixed filling rate reaches at 40% o'clock, and ore pulp just spills from the feed pipe outer wall, seals plugging leaks with charging, and is easy to wear because of the charging sealing, can't stop leak husky water.Once discharging opening was dwindled, actual mixed filling rate is increased to more than 45%, and it is serious that not only charging aperture leaks husky water, and because of the blanking angle reduces, the steel ball ore is stuck in the feed pipe, and is forced to stop.The grinding machine great majority use associating (cydariform) dispenser now, actual mixed filling rate is about 48%, and abrasive material and material are returned to the dispenser centre bore by charging aperture in the cylindrical shell, has leakage problems in various degree for the feed basin mouth, during parking, they blow back into dispenser by cylindrical shell and spill.As
3.2 * 3.1m grate ball mill Ceng Yin blows back into the steel ball of ore deposit case under the associating dispenser and ore and removes in time that associating dispenser screw feeder spoon head is stuck when driving, the broken and accident of displacement in top, charging main bearing seat basis.Also once carried out actual mixed filling rate and be increased to commerical test about 55%, though treating capacity increases, load descends on the contrary, leaks ore (slurry) in a large number for the feed basin mouth and is forced to stop using.The shortcoming of therefore existing grinding machine feeder is: complex structure, there is seepage, and the pack completeness of cylindrical shell is low, and the energy consumption height.
The utility model content
The utility model solves existing grinding machine feeder design complexity exactly, has seepage, energy consumption height, makes the little problem of grinding mill barrel pack completeness.
The technical scheme that the utility model solves is: grinding machine is pushed to feeder entirely, it comprises the jatharapanvartanasana urceolus and is positioned at urceolus and the central shaft coaxial with urceolus, the inwall of urceolus is fixed with some spirals (spiral head number is made as n, the helical angle angle is made as B), and nB 〉=360 degree; The spiral bottom is connected with outer tube inner wall, and the periphery of central shaft and the top of spiral are connected.
Adopt technique scheme, substitute former charging aperture (basin) when the utility model uses, when the barrel diameter of grinding machine hour, urceolus can adopt cylindrical, central shaft can be identical with circular outer cylinder length; When the diameter of the cylindrical shell of grinding machine is big, urceolus can be done tapered, central shaft is shorter than urceolus center line, under above-mentioned like this two kinds of situations, material pushes through the spiral rotation material is delivered in the cylindrical shell, because nB 〉=360 degree, spiral constitutes totally-enclosed to cylindrical shell, guaranteed that the radial clearance place between time funnel (pipe) and the urceolus small end does not have material, so it can " not tell material " or seepage
In sum, the beneficial effects of the utility model are: because totally-enclosed to cylindrical shell, only meeting charging can " not told material " and also can not produced seepage, makes the pack completeness of cylindrical shell can reach more than 55%, and is energy-conservation more than 30%; Because the utility model is simple in structure, therefore in light weight, cost is low.

The specific embodiment
The utility model is the bigger situation of grinding mill barrel diameter as shown in Figure 2, and it comprises taper urceolus 5 and central shaft 7, and for making the central shaft quality little, central shaft 7 is made of the capping 6 of straight tube and sealing straight tube one end.Urceolus 5 is divided into less front end of diameter of section and the bigger rear end of diameter of section, and urceolus 5 inwalls are fixed with spiral 3, and spiral head number is made as 4, the helical angle angle is made as 180.Straight tube is located in the rear end and is coaxial with urceolus 5, and between straight tube periphery and the rear end inwall, spiral 3 bottoms and urceolus 5 inwalls are connected, and the top of the periphery of central shaft 7 and spiral 3 is connected, and urceolus 5 front ends are feeding screw, and helical angle is 90 degree.
In use, can determine a number, helical angle angle and the spiral height of spiral, reach the best effect that pushes according to actual conditions.
