Abstract
The utility model discloses a device for online detection of a material bed thickness of a vertical roller mill. The device comprises a magnet which is arranged on a grinding roller rocker component, and a micro-pulse sensor and a signal conversion module which are adaptive to the magnet, wherein the micro-pulse sensor is arranged on a static part and is used for inducing displacement variation of the magnet and transmitting a generated magnetic induction signal to the signal conversion module; and the signal conversion module is used for converting the magnetic induction signal into material bed thickness. The device disclosed by the utility model can detect material bed thickness in real time online and reflect variation of the material bed thickness, so that central control can regulate process parameters of a vertical mill in real time depending on the variation of the material bed thickness, thereby reducing vibration and guaranteeing stable operation of the vertical mill.
Description
Technical field
The utility model relates to a kind of thickness detection apparatus, particularly a kind of device that detects online thickness of feed layer for vertical roller grinder.
Background technology
Vertical Mill is a kind of energy-conservation milling equipment that is widely used at present the industries such as cement, electric power, mining, iron and steel.Its operation principle is: material is fallen mill central authorities from feed opening, moves and be subject to rolling of grinding roller to the mill edge under the effect of centrifugal force, forms the bed of material, through grinding, by screening installation, qualified fine powder is selected.Previous Vertical Mill is mainly used in the pulverizing cement raw material, because the raw material bed of material is thicker, the material bed is more stable, and grinding machine operates than being easier to, but along with increasing of grinding machine grinding material kind, especially materials such as grinding slag, clinker and coal, the bed of material is thinner, and the material bed is difficult for stable, and easily destroy, cause the vibration of grinding machine, cause stopping mill, impact is produced.
Summary of the invention
The utility model provides a kind of device that detects online thickness of feed layer for vertical roller grinder for solving the technical problem that exists in known technology, this device can detect thickness of feed layer at any time in the debugging of grinding machine and production process, be convenient to middle control adjusting operation parameter, made the grinding machine steady running.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of vertical roller grinder detects the thickness of feed layer device online, comprise the magnetic patch that is arranged on the grinding roller rocker arm assembly, micropulse sensor and the signal conversion module adaptive with described magnetic patch, described micropulse installation of sensors is on stationary parts, the change in displacement of the described magnetic patch of described micropulse sensor sensing produces the magnetic induction signal and passes to described signal conversion module, and described signal conversion module changes into thickness of feed layer with described magnetic induction signal.
Described micropulse installation of sensors is on the rocker arm shaft bearing.
Advantage and the good effect that the utlity model has are: thickness of feed layer can be detected in real time online, the variation of reaction material layer thickness, make middle control can in time adjust according to the variation of thickness of feed layer the technological parameter of Vertical Mill, to reduce vibration, guarantee the Vertical Mill steady running.Especially in the debugging of vertical mill system initial stage, detect the bed of material and change, adjustment feeding capacity, adjustment hydraulic control parameter have very important effect.

The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1～Fig. 2, a kind of vertical roller grinder detects the thickness of feed layer device online, comprise the magnetic patch 3 that is arranged on grinding roller rocker arm assembly 4, micropulse sensor 2 and the signal conversion module adaptive with described magnetic patch 3, described micropulse sensor 2 should be arranged on stationary parts, in the present embodiment, described micropulse sensor 2 is fixed on rocker arm shaft bearing 7 by sensor stand 1.The change in displacement of the described micropulse sensor 2 described magnetic patch 3 of induction produces the magnetic induction signal and passes to described signal conversion module, and described signal conversion module changes into thickness of feed layer with described magnetic induction signal.
Operation principle of the present utility model:
In process of production, mill 6 rotates under the drive of transmission device, grinding roller 5 and mill counter-rotation, the material that is transported on mill 6 is milled, thickness of feed layer t changes at any time according to actual condition, making grinding roller 5 drive rocking arm rotates along rocker arm shaft, magnetic patch 3 positions that be fixed on grinding roller rocker arm assembly 4 this moment change, this changing value is collected by micropulse sensor 2, change into thickness of feed layer by the signal conversion unit, make middle control the variation of thickness of feed layer t can be detected, the adjusting process manufacturing parameter, guarantee the grinding machine steady production at any time.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
