Abstract
The utility model discloses a multifunctional lining plate in a tube mill. The multifunctional lining plate in the tube mill comprises a base and an arc-shaped dust plate, wherein the lower end of the dust plate is fixed on the base, a blocking plate is perpendicularly fixed on the back of the dust plate, and the blocking plate is provided with a strip-shaped central hole. Due to the fact that no new equipment is added in an existing tube mill, but only an ordinary activation lining plate is innovated, the multifunctional lining plate is simple in structure and easy to install, and integrate an activation function, a deceleration function and a dust-raising function. The over-grinding disadvantage which the ordinary activation lining plate has is transformed to an over-grinding reducing advantage after the ordinary activation lining plate is reformed to the multifunctional lining plate. The multifunctional lining plate further improves grinding efficiency of the tube mill and achieves the purpose of saving energy and lowering consumption.
Description
Technical field:
The utility model relates generally to the multi-functional liner plate in a kind of tube mill, and it is widely used in the grinding engineering field of materials such as cement, slag, flyash, nonmetallic ore.
Background technology:
Tube mill is a kind of equipment that is widely used in material grindings such as cement, slag, nonmetallic ore.Its small investment, properties of product are reliable and stable, but the energy consume significant, effective rate of utilization is low.Improving mill efficiency, saving energy and reduce the cost is current tube mill most important.
Have the serious grinding problem of crossing in the tube mill, it is a low important reasons of its mill efficiency.Investigate from grinding process, as if in grinding process, the fineness to the longitudinally of mill tail develops material along grinding machine from bistrique in mill, and is from coarse to fine, is accept until going out grinding rate, forms a rational fineness gradient.If further analyse in depth, from the cross section of every bit longitudinally, material particles thickness great disparity, fineness is extremely inhomogeneous.On each cross section in the section storehouse, the accept below the 45 μ m all is in the great majority, but also has a certain amount of thick material that does not conform with fineness requirement simultaneously.In order to reach the requirement of grinding rate, have to accomplish with the long grinding time.Like this, in mill,, in the fineness evolution, collect bigger and bigger to the percentage composition that grinds the tail accept by bistrique along grinding machine grinding material longitudinally, but must wait for whole materials reach the fineness index qualified after, can discharge outside the mill.The problem here is that qualified fines can not in time be discharged in the mill, and they play blanketing to the grinding of thicker material, expend the too much grinding time, and mill efficiency is reduced.
Activation lining board is a kind of a kind of Increasing Production and Energy Saving equipment that is widely used on all kinds of tube mills.Its advantage mainly contains two: the one, can improve the locomitivity and the milling capacity of abrasive media, and the 2nd, the material flow that can slow down when material flow is too fast in the mill, can also significantly improve the interior material ball ratio of mill.Shortcoming is to have aggravated to cross grinding, because the grinding time of the qualified micro mist of fineness has also been prolonged by inappropriate.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of locomitivity that can improve abrasive media to be provided, improve material ball ratio in the mill, can reducing the multi-functional liner plate of grinding again.
The utility model is realized through following technical scheme:
Multi-functional liner plate in a kind of tube mill, it is characterized in that: include the airborne dust plate of base and arc, airborne dust plate lower end is fixed on the base, and the back side of airborne dust plate is fixed with striker plate, has the centre bore of bar shaped on the striker plate.
Multi-functional liner plate in a kind of tube mill is characterized in that: on the back side of said striker plate perpendicular to the airborne dust plate.
Multi-functional liner plate in a kind of tube mill, it is characterized in that: said base is the ripple liner plate, the central authorities of ripple liner plate are provided with is convenient to the screw that it is connected with the tube mill cylindrical shell.
Multi-functional liner plate in a kind of tube mill, it is characterized in that: said base is fixed on the tube mill cylinder inboard wall.
Multi-functional liner plate in a kind of tube mill, it is characterized in that: the height of said airborne dust plate is 50%～60% of a tube mill cylindrical shell radius.
Multi-functional liner plate in a kind of tube mill, it is characterized in that: the height of said striker plate is 35%～45% of a tube mill cylindrical shell radius.
The utility model is to be made up of base, striker plate and airborne dust plate etc.Each member is cast with wear-resisting alloy steel becomes a firm integral body.
Said base is common standard ripple liner plate, wide 250mm, and thick 45～65mm, there is a Φ 33mm screw in central authorities, are convenient to be connected with grinding mill barrel.
The about 50mm of said striker plate thickness highly is 35%～45% of a tube mill radius.
Said airborne dust plate is an arc, and its arc radius is different and different according to the diameter of tube mill.Its thickness is 25～30mm, and wide 100～150mm highly is 50%～60% of a tube mill radius.
Said centre bore is positioned on the striker plate, the wide 50～80mm in hole.
The utility model is to develop according to the material wind selection theory.Make the airborne dust plate of arc at multi-functional liner plate direct casting, when tube mill rotated, material was kicked up by the airborne dust plate in the tube mill cylindrical shell, and micro mist disperses in wind, and is taken out of outside the mill by wind-force.According to the Ctokc law, the critical wind velocity when material particles can be in suspended state in air is proportional to the square root of this particle diameter.Therefore, in theory, when ventilating in the tube mill, the micro mist that particle is enough tiny should be in suspended state, and is taken out of outside the mill by wind-force.Yet, in fact, because the thickness particle is mingled in abrasive body in tube mill, and reason such as the streams momentum is big, the subparticle that most sizes are enough tiny all is in the deposition attitude, can't be taken out of outside the mill by wind-force.Multi-functional liner plate can be kicked up material in the mill, makes the micro mist of deposition attitude in wind, disperse and be in suspended state, and under the effect of wind-force, in time discharge grind outside.So just strengthen selection by winnowing in the mill, reduced the grinding phenomenon, improved mill efficiency.
The utility model has been transformed common activation lining board, makes it increase airborne dust selection by winnowing function.Promptly in the activation steel section that keeps common activation lining board, the material flow that slows down, increase the airborne dust function, reduced micro mist time of staying and mistake grinding phenomenon in the tube mill cylindrical shell.
During work, multi-functional liner plate rotates with the tube mill cylindrical shell, and material is kicked up, disperseed by the airborne dust plate in the tube mill cylindrical shell, and micro mist suspends in wind and moves to discharge end together with the wind, discharges outside the mill.Significantly reduce and " crossed grinding " phenomenon.
The utility model has the advantages that:
In grinding machine, do not increase new equipment, only common activation lining board is carried out innovating reform, simple in structure, be easy to install, integrate activation, deceleration, airborne dust simultaneously.Common activation lining board aggravated the shortcoming of grinding, through after the transformation of the utility model, had been transformed into the advantage that reduced grinding.Further improve the mill efficiency of tube mill, reached energy saving purposes.
