Abstract
The utility model relates to a cooling liquid magnetization filter in cold rolling strip steel equipment. The cooling liquid magnetization filter in cold rolling strip steel equipment can filter iron filings in cooling liquid and quickly eliminate the filtered iron filings simultaneously, can be easy to demagnetize, and can improve the filtration accuracy and the period of circular use of the cooling liquid. The utility model is composed of a driving square shaft, a driven square shaft, a magnetic rod chain, and a sewage collecting cart, wherein, the magnetic rod is composed of magnetic steel blocks, a magnetism insulating sheet, an outer sleeve pipe, a joint, etc., and the polarities of the magnetic steel blocks are arranged reversely. The utility model is mainly used for filtering cooling liquid in cold rolling strip steel equipment.
Description
The utility model belongs to the technical field that adopts magnetic force or electrostatic separation method separating solids material device.
Contain a large amount of iron filings in the used cooling fluid during cold-strip steel, at present, domestic band steel manufacturing enterprise all uses a kind of magnetization filter of core structure to come cooling fluid is filtered.Its structure is that 4 magnet steel posts are installed in the tube, and an import is arranged at the bottom of tube, and an outlet is arranged at top.During work, cooling fluid flows in the tube from import, directly contacts with the magnet steel post, and iron filings are magnetized by the magnet steel post and are adsorbed on the surface of magnet steel post in the process that rises along with liquid level, and the cooling fluid after the filtration is overflowed from outlet.This class filter is along with the lip-deep iron filings of magnet steel post is on the increase, and filtering accuracy just obviously reduces thereupon, thereby influences steel product quality, and the cycle that recycles of cooling fluid have only about one month, simultaneously, the demagnetization difficulty, the workload of the iron filings on elimination magnet steel post surface is bigger.
The purpose of this utility model is to design a kind of iron filings in can the filtering cooling fluid, demagnetization and remove the magnetizing filter of the iron filings that are filtered off in the filter rapidly easily again, thus improve the filtering accuracy of cooling fluid, prolong the cycle that recycles of cooling fluid.
Fig. 1 is the schematic diagram of the utility model master apparent direction.
Fig. 2 is the schematic diagram of the right apparent direction of the utility model.
Fig. 3 is the structural representation of magnetic core stick.
Fig. 4 is the schematic diagram that magnetic material polarity is played a reversed role and placed in the magnetic core stick.
The utility model is made up of parts such as active square shaft 1, passive square shaft 3, magnetism stick chain 2, the dirty dollies 5 of collection, and magnetism stick chain 2 is in series by several magnetism sticks, some magnetism stick chains 2 Be arranged in respectively on active square shaft 1 and the passive square shaft 3 by certain spacing and identical polar direction, every magnetism stick chain 2 passes from the dirty dolly 5 of collection separately, wherein, magnetism stick is made up of magnetic steel ingot 6, exhausted magnetic material piece 8, outer tube 7 and joint 9 etc., the polarity placement of playing a reversed role between the magnetic steel ingot 6, and with exhausted magnetic material piece 8 two adjacent polarity magnetic steel ingot of placing of playing a reversed role is separated, outer tube 9 two-port of magnetism stick adopt the roll extrusion mode to seal.
The course of work of the utility model in tank for coolant 4 following (referring to Fig. 1, Fig. 2): magnetism stick chain 2 under the effect of external force around two square shafts 1,3 shuttling movement from top to bottom along clockwise direction, rising along with magnetism stick, be adsorbed on after iron filings in the cooling fluid are magnetized and take liquid level on the magnetism stick out of, magnetism stick is crossed initiatively and is begun to descend behind the square shaft 1, when collecting dirty dolly 5, iron filings on the magnetism stick are collected dirty dolly 5 to be eliminated, after the circulation, the iron filings in the cooling fluid are removed so repeatedly.
The utility model compared with prior art can be removed the iron filings that are filtered off in the filter rapidly basically all in the filtering cooling fluids in the iron filings, and demagnetization easily.The filtering accuracy of cooling fluid can reach 50～100 μ m, has reached the requirement of the zinc-plated heavy plate mill of domestic and international rolled steel of the same type to cooling fluid, and the cycle that recycles of cooling fluid is by more than about one month time lengthening to three of prior art month.
Embodiment of the present utility model is: the magnetic steel ingot 6 in the magnetism stick adopts permanent magnet material, and exhausted magnetic material piece 8 adopts the bakelite plate material, and the length of every magnetism stick is 450～550mm, and outer tube 7 adopts stainless-steel seamless pipe.
Claims (2)
1, cooling fluid magnetizing filter in a kind of cold-strip steel equipment, it is characterized in that by active square shaft 1, passive square shaft 3, magnetism stick chain 2, collecting dirty dolly 5 parts such as grade forms, magnetism stick chain 2 is in series by several magnetism sticks, some magnetism stick chains 2 are arranged in respectively on active square shaft 1 and the passive square shaft 3 by certain spacing and identical polar orientation, every magnetism stick chain 2 passes from the dirty dolly 5 of collection separately, wherein, magnetism stick is by magnetic steel ingot 6, exhausted magnetic material piece 8, compositions such as outer tube 7 and joint 9, the polarity placement of playing a reversed role between the magnetic steel ingot 6, and separate with exhausted magnetic material piece 8 magnetic steel ingot of placing 6 of will two adjacent polarity playing a reversed role, the outer tube 7 two-port employing roll extrusion mode of magnetism stick is sealed.
2, by cooling fluid magnetizing filter in the described cold-strip steel equipment of claim 1, it is characterized in that the magnetic steel ingot 6 in the magnetism stick adopts permanent magnet material, exhausted magnetic material piece 8 adopts the bakelite plate material, and the length of every magnetism stick is 450～550 millimeters, and outer tube 7 adopts stainless-steel seamless pipe.
