Abstract
The invention relates to a cement and slag grinding apparatus, in particular to a regulating device of a vertical roller mill for cement and slag. The regulating device is arranged outside a shell of the vertical roller mill and is convenient for regulating a gap between an inside movable ring and a static ring. The regulating device comprises a regulating screw stem 5, a fixed seat 7, a regulating nut 6 and fastening nuts 8 and 9. When the gap S between the movable ring and the static ring is regulated, the fastening nuts 8 and 9 are firstly loosened, and then the regulating nut 6 is rotated, therefore, the regulating screw stem 5 can move up and down so as to drive the static ring of a sieve frame 2 in the mill to move up and down. The gap S between the static ring 1 and the movable ring 10 and is regulated to adapt the working requirement of working condition variations, therefore, the labor intensity of an operator is greatly reduced, and the working environment is improved.
Description
Technical field:
The present invention relates to a kind of cement, slag milling equipment, special vertical roll grinder is regulated built-in rotating ring, the outside adjusting device in stationary ring gap.
Background technology:
In cement, slag milling process, obtained extensive use as vertical roll grinder.In the vertical roll grinder structure, set inner sieving mechanism, the thickness of feed layer of vertical roll grinder is about to that the gap of rotating ring in the inner screening plant and stationary ring guarantees.When the bed of material is blocked up, strengthen the gap between rotating ring, the stationary ring, reduce thickness of feed layer.The bed of material is crossed when approaching, and dwindles the gap between rotating ring, the stationary ring, increases thickness of feed layer.The gap of adjusting between rotating ring, the stationary ring must be shut down, and carries out the manual adjustment (see figure 2) in mill, because screen frame (unit) is heavier, when adjusting, must just can finish by instruments such as chain block, crowbars at every turn.Because dust is many in the mill, the temperature height, workman's operation is very difficult, and the adjusting time is also long, influences mill efficiency.A kind of vertical roll grinder adjusting device is implemented machine and is operated outward, regulates built-in dynamic and static czermak space easily, guarantees thickness of feed layer, guarantees vertical roll grinder stable operation.
Summary of the invention:
The object of the invention is to provide a kind of adjusting device of vertical roll grinder, with easily and fast the adjusting rotating ring and the gap of stationary ring, solves the problems referred to above that exist in the background technology.
Technical solution of the present invention is:
In the outer setting adjusting device of vertical roll grinder, built-in rotating ring and the stationary ring gap of convenient adjusting.Adjusting device is made up of adjustment screw rod, holder, adjusting nut, clamp nut.When regulating the gap, draw back clamp nut earlier, rotate nut then and regulate the screw mandrel rotation, thereby the stationary ring that drives on the inner screen frame (unit) is upper and lower mobile, moves up and down by stationary ring, regulates the gap between the dynamic and static ring easily.
The invention has the beneficial effects as follows:
Since in the outer setting of vertical roll grinder adjusting device, can under non-stop-machine situation, regulate the gap of rotating ring and stationary ring freely, improved operator's operating environment and labour intensity, guarantee long-term, the stable operation of vertical roll grinder.
Description of drawings:
Accompanying drawing 1 is the structural representation of example of the present invention.
Fig. 2 is the structural representation of existing vertical roll grinder internal regulation.
Fig. 1: stationary ring 1, screen frame (unit) 2, fastening bolt 3, housing 4, adjusting screw(rod) 5, adjusting nut 6, holder 7, fastening bolt 8, fastening bolt 9, stationary ring 10, mill 11
The specific embodiment:
Below in conjunction with the accompanying drawings, further specify the present invention by embodiment.
Fig. 1 is the structural representation of adjusting device of the present invention.Comprise adjusting screw(rod) 5, adjusting nut 6, holder 7, clamp nut 8, clamp nut 9, holder 7 is by being bolted on the housing 7.When regulating the gap S of rotating ring 10 and stationary ring 1, must unclamp clamp nut 6 and clamp nut 8 earlier, rotate adjusting nut 6 then, be fixed on stationary ring 1 on the screen frame (unit) 2 under the drive of adjusting screw(rod) 5 and fastening bolt 3, can move up and down, just can regulate the gap S of 1 of rotating ring 10 and stationary ring easily.Like this, in the outside of housing 4, just be free to regulate rotating ring and stationary ring gap.
Claims (2)
1. the adjusting device of a vertical roll grinder, comprise adjusting screw(rod), holder, adjusting nut, clamp nut etc., it is characterized in that: unclamp clamp nut earlier, rotate adjusting nut then, adjusting screw(rod) can move up and down like this, thereby the stationary ring on the drive screen frame (unit) moves up and down, and has regulated the gap of rotating ring and stationary ring.
2. according to claim, described adjusting device is characterized in that: adjusting device is arranged on the outside of vertical roller grinder engine housing.
