Abstract
The utility model relates to a magnetic disc with a non-magnetic area for a magnetic water treatment device, which is characterized in that the surface of the magnetic disc (1) with the non-magnetic area consists of a magnetic area (10) and the non-magnetic area (11), wherein the non-magnetic area (11) is in the shape of a fan, the surface area thereof accounts for one tenth to one eighth of the surface area of the magnetic disc (1) with the non-magnetic area. The magnetic disc is the magnetic disc with the non-magnetic area, and the fan-shaped non-magnetic area is arranged on the magnetic disc, thereby leading sheet iron, silt and other wastes not to be absorbed in the non-magnetic area of the magnetic disc; furthermore, a rigid rotating scraper can ensure the tight contact with the non-magnetic area of the magnetic disc, when the non-magnetic area rotates to the position of the rigid rotating scraper, the residual wastes on the surface of the magnetic disc are very easy to be scrapped off.
Description
Technical field
The utility model relates to the key part of water treating equipment, and specifically a kind of magnetic force water treating equipment are with being with no magnetic region disk.
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.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 with the no magnetic region of band disk, sets up no magnetic region in disk, 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 be withs no magnetic region magnetic disk surface by being made up of magnetic region and no magnetic region with the no magnetic region of band disk, and no magnetic region is fan-shaped, its surface-area account for be with that no magnetic region magnetic disk surface amasss 1/10 to 1/8.
The beneficial effects of the utility model are:
Disk of the present utility model is the no magnetic region of band disk, on disk, be provided with segmental and do not have the magnetic region, make waste materials such as iron sheet, silt can not be adsorbed on the no magnetic region of disk, the rigidity rotation scraper just can guarantee that not having the magnetic region with disk contacts tightly, when no magnetic region forwarded rigidity rotation scraper place to, the remaining waste material of magnetic disk surface was easy to be scraped.
Use magnetic force water treating equipment 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 structural representation that band of the present utility model does not have the magnetic region disk.
Among the figure: 1 is that the no magnetic region of band disk, 10 is that no magnetic region, 2 is the disk rotation axis for magnetic region, 11 is arranged.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of magnetic force water treating equipment are with disk 1 surface, no magnetic region by being made up of magnetic region 10 and no magnetic region 11 with the no magnetic region of band disk, and no magnetic region 11 is fan-shaped, and its surface-area accounts for 1/10 to 1/8 of the no magnetic region of band disk 1 surface-area.Be with no magnetic region disk 1 to be fixed on the disk rotation axis 2.
The disk of magnetic force water treating equipment of the present utility model is the no magnetic region of band disk 1, on disk, be provided with segmental and do not have magnetic region 11, make waste materials such as iron sheet, silt can not be adsorbed on the no magnetic region 11 of disk, the rigidity rotation scraper just can guarantee that with fixed doctor not having magnetic 11 districts with disk contacts tightly, when the rigidity rotation scraper turns to the disk that is adsorbed with body refuse when magnetic region 10 is arranged, thorough waste materials such as scraping iron sheet, silt, adopt rigidity scraper 8, intensity is better, it is yielding to have overcome the adhesive tape scraper, the defective that the dynamics of striking off is more weak.
Claims (1)
1. magnetic force water treating equipment is characterized in that band no magnetic region disk (1) surface by having magnetic region (10) and no magnetic region (11) to form with the no magnetic region of band disk, and no magnetic region (11) are fan-shaped, and its surface-area accounts for 1/10 to 1/8 of band no magnetic region disk (1) surface-area.
