Description
Technical field
The present invention relates to metallurgy industry steel plate finishing reconditioning manufacture fields, more specifically on a kind of grinding mill
Water curtain blow device.
Background technique
Plate product has surface quality very stringent standard and requirement, therefore for surface of steel plate common deficiency
Such as foreign matter indentation, scuffing, impression, roll marks, edge line defect require additional reconditioning process usually to eliminate defect.If
Defect is local small area, usually only need to manually use abrasive machine reconditioning；But if defect is that overall length is big on the steel plate
When area distributions, artificial reconditioning workload is huge and low efficiency, this just needs to carry out the efficient reconditioning operation of mechanization with grinding mill.
Existing grinding mill structure is traversing as shown in Figure 1, be mounted on liftable bistrique 4 for the husky belt of reconditioning steel plate 3
Trolley 2 drives liftable bistrique 4 for the positioning in 3 width direction of steel plate, and rack trolley 1 drives cross traveling trolley 2 can be along steel
3 length direction of plate moves back and forth, to realize mechanization reconditioning operation.
According to depth of defect, defect bandwidth etc., operator can be automatically performed more by grinding mill after parameter setting
Reciprocal reconditioning, efficiency are obviously improved passage back and forth.But existing grinding mill encounters following two problems demands in actual use
It solves:
1. generate a large amount of metallic particles shape dust in mill processes, the bistrique position producer design of grinding mill have one it is low
Pressure point spray waterpipe, the purpose is to cool down reconditioning belt with shower water to extend belt service life.And local depression shower water
Use so that a part of metallic particles dust is attached to surface of steel plate through water sedimentation, sediment is difficult to clean up after air-drying, directly
Connect influence plate surface quality, thus it is subsequent also need artificial special cleaning, it is very complicated；Another part dust then drifts air
Middle pollution environment.
2. grinding mill high-speed rotating belt and surface of steel plate grinding in reconditioning operation generate amount of heat, so that reconditioning
Steel plate easily causes reconditioning position part micro-deformation due to uneven heating when thin plate, is unfavorable for Strip Shape Control.Although as above-mentioned
There is shower water, but the low pressure point shower water is mainly used for reducing belt temperature, Strip Shape Control is acted on unobvious.
Number of patent application 201720216029.2 discloses a kind of " milling train and its strip blow device ", strip purging dress
It sets including water supply pipe, is provided with valve on the water supply pipe；Scavenging pipeline, the input end of the scavenging pipeline and the confession
The water outlet of water lines is connected to, and the iron filings of strip upper surface blow off from the water energy that the outlet end of the scavenging pipeline is flowed out.
Milling train is entered with strip so as to avoid the iron filings for falling in strip upper surface, avoids the case where influencing belt steel product quality.
The device, which scrapes a small amount of iron filings generated for steel edge portion and finishing mill inlet side-guiding-board, has purging effect, but the disadvantage is that such as
When fruit iron filings or more foreign matter, the scavenging pipeline of linear type arrangement is unfavorable for iron filings or foreign matter excludes upper surface of steel plate in time,
It is easy to generate packing phenomenon in purging point leading portion.In addition the device is only applicable in unidirectional purging, there is great limitation in use
Property.
Summary of the invention
In view of the above defects of the prior art, the object of the present invention is to provide the water curtain purgings on a kind of grinding mill
Device, the water curtain which sprays can effectively adsorb and precipitate the metallic particles dust generated when milling and be purged tapping
Plate surface, and the balanced plate face temperature of energy, are conducive to the Strip Shape Control of thin plate.
To achieve the above object, the present invention adopts the following technical scheme:
Water curtain blow device on a kind of grinding mill, on two pedestals of grinding mill upper spider trolley, comprising:
U-shaped shape is arranged in inlet pipeline, the inlet pipeline, and the both ends of U-shaped inlet pipeline are connected with bracket respectively
Connecting tube, two bracket connecting tubes are respectively provided with the shape that is in the shape of the letter V, and are respectively arranged on two pedestals of rack trolley, the water inlet pipe
Road is additionally provided with shut-off valve and three-way magnetic valve；
Nozzle, the nozzle have it is several, be respectively connected in two bracket connecting tubes, each nozzle is respectively provided in flat
Flat-shaped pot construction, inner hollow, nozzle tip position open up fluted, apopore are intensively arranged side by side on groove, out
Angle is formed between the upper surface of steel plate placed on water hole axis and the grinding mill, nozzle tail end is connected in institute by three-way elbow
It states in bracket connecting tube；
Branch shut-off valve is additionally provided in the every bracket connecting tube.
The three-way magnetic valve includes two electromagnetic controllers.
There are two the shut-off valve tools, is respectively arranged on the two sides of three-way magnetic valve.
Branch shut-off valve there are four being all provided in the every bracket connecting tube.
The angle between upper surface of steel plate placed on the water outlet axially bored line and the grinding mill is 30~45 °.
It is to be threadedly coupled between the nozzle tail end and three-way elbow.
The V-shape wedge angle position of two bracket connecting tubes is oppositely arranged, and towards inside.
The V-shape wedge angle position of two bracket connecting tubes is connected to the both ends of inlet pipeline respectively.
In the above technical solution, water curtain blow device on a kind of grinding mill provided by the present invention can be according to stone roller
The direction of travel of rack trolley when grinding machine reconditioning steel plate is automatically controlled by three-way magnetic valve and replaces opening and closing switching two-way V-type
The water of bracket connecting tube supplies.The high-pressure hydraulic sprayed in the flat shaped nozzle being intensively arranged side by side in bracket connecting tube is in steel plate
On same full width orientation form V-arrangement polyline shaped high pressure water curtain, not only improve and effectively settle the metallic particles dust that generates when grinding,
It prevents it from drifting and pollutes environment in air, and will effectively can be adsorbed through water and be deposited on the metallic particles of surface of steel plate to steel
The both sides of the edge direction of plate is purged from steel plate, prevents its deposit adhesion from having an impact on the steel plate to plate surface quality.Simultaneously
In reconditioning thin plate, high pressure water curtain can effectively neutralize the amount of heat generated when grinding, be more advantageous to the plate shape control of thin plate in this way
System prevents it from causing local micro-deformation caused by uneven heating because of grinding heat.
