Abstract
The utility model relates to a rigid rotating scraper for a magnetic water treatment device, which is characterized in that the rigid rotating scraper (1) comprises a discoid metal plate (10), wherein a plurality of adhesive tapes (12) are distributed on the upper surface and the lower surface or one of the two surfaces of the metal plate (10), an upper pressure plate (11) is arranged on the metal plate (10), and the adhesive tapes (12) are fixed by a pressure plate (11). The rigid rotating scraper is inserted into a gap of a magnetic disc for rotating, the flexible adhesive tapes are fixed on the rigid plate surface without deformation and in tight contact with the surface of the magnetic disc, the rigid rotating scraper can not only scrap off impurities on the surface of the magnetic disc, but also scrap the impurities and wastes accumulated on the fixed scraper into a sludge slot.
Description
Technical field
The utility model relates to the key part of water treating equipment, specifically a kind of magnetic force water treating equipment rigidity rotation scraper.
Background technology
At present, utilize magnetic force absorption ferromagnetic material and the technology separated is widely used already in the iron mine beneficiation engineering of iron and steel enterprise from other material.Utilize equipment such as the produced drum-type magnetic separator of magnetic separation technique, disk-type magnetic separator, powdered iron ore is sorted out from ore pulp, improve the ferrous grade of fine iron breeze, existing still in the ore dressing workshop section widespread usage of iron mine.
In the 1970s and 1980s in last century, abroad just have magnetic separation technique is applied in the wastewater treatment, as precedent just being arranged in countries such as Sweden, Japan, Britain, Germany, the U.S..Magnet all adopted common ferrite at that time, because common ferrite magnetic intensity of field is low, it is short to contain the magnetic life-span, so magnetic separation technique is extensively promoted in water treatment field.
The late nineteen eighties, rare earth permanent-magnetic material is succeeded in developing, and it has, and magneticstrength is big, magnetic energy product is high, contain advantages such as the magnetic life-span is long, and its appearance impels magnetic separation technique also to advance greatly, and magnetic separation technique is applied in the engineering of water treatment gradually.
Middle nineteen nineties, China begins to have the magnetic force water treating equipment to be applied in the operation turbid circulating water treatment systems such as Steel Plant's continuous casting, steel rolling.
Steel Plant's continuous casting, molten steel ingot casting, the Steel Rolling operation of steel rolling process for producing earlier.Need a large amount of water coolants in process of production, because water coolant directly contacts with hot steel ingot, steel, contain impurity such as a large amount of iron scales, oils, silt in the waste water of discharge, cooling recycles after handling.The magnetic force water treating equipment just are applied to remove impurity.
Existing magnetic force water treating equipment are magnetic disc type on the China market at present, promptly form disk groups by a plurality of disks.When the circulating waste water of continuous casting, steel rolling process eliminating passed through disk groups disk gap, iron scale, silt, oils contained in the water were adsorbed onto magnetic disk surface through the flocs unit that the medicament effect forms under the action of a magnetic field, strike off with scraper again.
Existing magnetic force water treating equipment are magnetic disc type on the China market at present, promptly form disk groups by a plurality of disks.When the circulating waste water of continuous casting, steel rolling process eliminating passed through disk groups disk gap, iron scale, silt, oils contained in the water were adsorbed onto magnetic disk surface through the flocs unit that the medicament effect forms under the action of a magnetic field, strike off with scraper again.Magnetic force water treating equipment disk is the key position of decision water treatment effect, is to utilize that impurity reaches the purpose of handling waste water in the magnetic field planar water that disk produces.Can disk not only affect disk to the surface impurity scraped clean in absorption behind the impurity, and the working efficiency in this cycle also affects the working efficiency of next cycle simultaneously.Still leave one deck impurity as magnetic disk surface, then the ability of next cycle absorption impurity will reduce greatly.Striking off of magnetic disk surface impurity is the key link of decision magnetic force water treating equipment treatment effect for this reason.
Summary of the invention
The purpose of this utility model is to provide a kind of magnetic force water treating equipment rigidity rotation scraper, and changing the adhesive tape scraper is the rigidity rotation scraper, has overcome the drawback of existing magnetic force water treating equipment.
The technical solution of the utility model is:
A kind of magnetic force water treating equipment rigidity rotation scraper, the rigidity rotation scraper comprises the disc metal sheet, two surfaces or the some adhesive tape of one of them surface arrangement about metal sheet, metal sheet is provided with top board, and adhesive tape is fixed by pressing plate.
Described adhesive tape cross-sectional shape is a trilateral, and its both sides respectively are provided with a pressing plate of fitting with it.
Described metal sheet respectively is evenly distributed with three adhesive tape in two surfaces up and down.
The beneficial effects of the utility model are:
The utility model novel structure, rational in infrastructure, stable, high efficient and reliable:
Rigidity of the present utility model is rotated in the scraper insertion disk slit and is rotated, its flexible adhesive tape is fixed on the rigid plate face indeformable, contact closely with disk face, it not only can strike off the impurity of disk face, the impurity, the waste material that accumulate on the fixed doctor can also be scraped in the body refuse groove.
Adopt the magnetic force water treating equipment of rigidity rotation scraper of the present utility model to increase, wherein remove suspended substance and oils and can improve more than 20% than domestic device processes effect of the same type.
Description of drawings
Fig. 1 is the two dimensional structure synoptic diagram of rigidity rotation scraper of the present utility model.
Fig. 2 is the side-looking structural representation of rigidity rotation scraper of the present utility model.
Among the figure: 1 is that rigidity rotation scraper, 10 is that metal sheet, 11 is that pressing plate, 12 is that adhesive tape, 2 is for rotating the scraper rotation axis.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of magnetic force water treating equipment rigidity rotation scraper, rigidity rotation scraper 1 comprises disc metal sheet 10, and in metal sheet two surfaces or the some adhesive tape 12 of one of them surface arrangement about in the of 10, metal sheet 10 is provided with top board 11, and adhesive tape 12 is fixing by pressing plate 11.Rigidity rotation scraper 1 is fixed on and rotates on the scraper rotation axis 2.
As preferably, metal sheet respectively is evenly distributed with three adhesive tape 12 in two surfaces about in the of 10.
Rigidity is rotated in the scraper 1 insertion disk slit and is rotated, its flexible adhesive tape 12 is fixed on the rigid metal plate 10 indeformable, contact closely with disk face, it not only can strike off the impurity of disk face, the impurity, the waste material that accumulate on the fixed doctor can also be scraped in the body refuse groove.
When rigidity rotation scraper 1 turns to the disk that is adsorbed with body refuse, thorough waste materials such as scraping iron sheet, silt, it is yielding to have overcome the adhesive tape scraper, the defective that the dynamics of striking off is more weak.
