Description
Technical field
The invention belongs to cement industry milling equipment technical field, particularly relates to vertical roller grinder mill bed of material stabilising arrangement and vertical roller grinder.
Background technology
Vertical Mill is widely used in cement, electric power at present, the energy-conservation milling equipment of one of the industries such as iron and steel.Vertical Mill is in running, and granular material is from the center feeding elephant trunk feeding directly over mill, and material drops on mill center.Mill rotates, and material is subject to the effect of centrifugal force, and helically wire moves to mill surrounding, enters grinding region.Grinding roller, under the effect of curved arm rod mechanism, applies downward normal pressure to the material in grinding region, grinding material.But some material is in the process to the movement of mill surrounding, grinding region can not be entered at once, and be introduced into the non-grinding region between two grinding rollers, then under the drive of mill rotation, enter grinding region again.Now, the bed of material on mill just has fluctuation.For ensureing that Vertical Mill can run well, controlling Vertical Mill thickness of feed layer is a very important link.When the mill bed of material fluctuates, the large current situation will cause that grinding machine current fluctuation is large and grinding machine vibration is bigger than normal, even grinding machine stop jumping.If when lining board for grinding discs and grinding roller roller shell may wear to the later stage, the fluctuation of the mill bed of material not only can cause the greatly even super rated current stop jumping of grinding machine current fluctuation, and the collision probability of grinding roller roller shell and lining board for grinding discs can be made to increase and damage grinding roller roller shell and lining board for grinding discs.
Stablize at present the mode of the bed of material more is that employing by spraying water in Vertical Mill, make the material increasing friction force in mill, thus ensure that material forms the more uniform bed of material of thickness on mill, reduce grinding machine vibration, this mode consumes a large amount of heat energy and DeGrain.Some external Vertical Mill manufacturers adopt auxiliary roller arrangement, its structure and home roll similar, the specification of auxiliary roller diminishes.Although add auxiliary roller grinding material between two home rolls, due to roller with exert pressure less, be subject to that material resistance is large, the degree of wear is high, mill efficiency is low, the impact of the factors such as manufacturing cost is high, not too suitablely promote.
In production practices, inventor finds that the method for the above stable bed of material all has larger defect, and result of use is not obvious and not easily adjust.Therefore, grinding disc of vertical mill bed of material stabilising arrangement how can cloth on mill equably under high density dust atmosphere in mill, after a certain amount of material of permission is thrown out of mill by mill edge, ensure the balance of gas in the interior inventory of mill and mill, thus on mill, forming the stable bed of material, the replacing simultaneously under the actual condition of grinding variety classes material how after rapid adjustment thickness of feed layer and its wearing and tearing does not affect continuous seepage thus ensures that the stable yields of Vertical Mill and the stability of running just become the problem being badly in need of solving.
Summary of the invention
The invention provides a kind of vertical roller grinder mill bed of material stabilising arrangement and vertical roller grinder for solving in known technology the technical problem that exists, and this vertical roller grinder mill bed of material stabilising arrangement effectively can control thickness of feed layer and play the effect of exhaust pre-compacted to the material between two home rolls.
A kind of vertical roller grinder mill bed of material stabilising arrangement, comprise lining board for grinding discs, also comprise the gripper shoe be welded on middle shell, gripper shoe is welded with the connection shaped steel of band elongated hole, this connection shaped steel is provided with laying shelf, the front end of laying shelf is provided with arc stone plate, and the plane perpendicular of arc stone plate is in the axis of vertical roller grinder.
The invention can also by the following technical solutions:
Preferred technical scheme, additional technical feature is: also comprise connecting lug, and connecting lug is arranged on middle shell, and is positioned at the top connecting channel-section steel, and connecting lug is connected with the brace of band elongated hole, the lower end of this brace is connected with the front end of laying shelf.
A kind of vertical roller grinder, comprise mill, middle shell, grinding roller and center feeding elephant trunk, mill is provided with lining board for grinding discs, also comprise the gripper shoe be welded on middle shell, gripper shoe is welded with the connection shaped steel of band elongated hole, this connection shaped steel is provided with laying shelf, and the front end of laying shelf is provided with arc stone plate, and the plane perpendicular of arc stone plate is in the axis of vertical roller grinder.
The invention can also by the following technical solutions:
Preferred technical scheme, additional technical feature is: also comprise connecting lug, and connecting lug is arranged on middle shell, and is positioned at the top connecting channel-section steel, and connecting lug is connected with the brace of band elongated hole, the lower end of this brace is connected with the front end of laying shelf.
The advantage that the invention has and good effect are:
Because the invention adopts technique scheme, mill bed of material stabilising arrangement is spread out one one uneven material dispersion equably by laying shelf under high density dust atmosphere in mill on mill, and by the material of accumulation exhaust pre-compacted, after a certain amount of material of permission is thrown out of mill by mill edge, ensure the balance of gas in the interior inventory of mill and mill, thus on mill, form the stable bed of material, the replacing after rapid adjustment thickness of feed layer and its wearing and tearing can not affect continuous seepage thus ensure the stable yields of Vertical Mill and the stability of running under the actual condition of grinding variety classes material simultaneously.This patent structure is simple, reasonable in design, effectively can prevent grinding roller impact to laying shelf when grinding material, reaches the vibration of reduction grinding machine and guarantees the object that Vertical Mill runs well.In addition, laying shelf height is easy to adjustment, and vulnerable part processing and manufacturing is easy, and fast changeable, ensure that material forms the stable bed of material on mill well, thus reduces the normal operation that Vertical Mill long-term stability is guaranteed in grinding machine vibration.
