Abstract
The invention relates to a device for disposing metal in sludge. The device comprises a magnetic field stirring area and a precipitate layering area which are connected with each other, wherein, the magnetic field stirring area is internally equipped with aeration stirring devices which are three stirring machines with foldable paddles, and the layering area is internally equipped with two layering plates. The device has the beneficial effects that as metal elements can be quickly separated out of the sludge by virtue of the stirring machines and a high-frequency magnetic field, the structure is simple and the production cost is low; and a synchronous cyclic conveying belt arranged at the bottom of the device can prevent the sludge at the lower layer from being adhered to the bottom, thus the operating efficiency is high.
Description
Technical field
The present invention relates to a kind of sludge treatment equipment, relate in particular to metal disposal plant in a kind of mud.
Background technology
In recent years, along with the input and the operation of a large amount of newly-built sludge treatment facilities, the increase at double of mud generation has become more and more important, the main path of recycling sludge when soilization is utilized to the recycling of mud.Anaerobic digestion can realize the minimizing of mud, innoxious and stabilization; And recyclable biogas, be one of most important means of sludge treatment, but it can not remove the metallic element that exists in the mud; Though these elements are not serious poisonous, harmful elements; But behind mud entering soil, long-term accumulation can exert an influence to pedosphere material cycle and soil ecosystem, and is bigger to the hazard ratio of environment.
Summary of the invention
The present invention provides metal disposal plant in a kind of simple in structure, easy to operate mud in order to overcome the above problems.
Technical scheme of the present invention is: comprise interconnective magnetic field stirring area and precipitated and separated district, be provided with the aeration agitation device in the stirring area of said magnetic field, said whipping appts is three folding oar stirrers, is provided with two demixing plates in the said demixing zone.
Said magnetic field stirring area and horizontal direction are 10-25 ° of angle.
Said magnetic field stirring area is the high-frequency impulse field regions.
The percentage that upper, middle and lower-ranking takes up space of said demixing zone is 80%, 13%, 7%.
Described demixing plate staggers successively and is 40-60 ° of angle with horizontal direction.
Said bottom of device is provided with the synchronised recycling conveying belt.
The present invention utilizes stirrer and high frequency magnetic field to go out the metallic element in the mud by sharp separation, and simple in structure, production cost is low, and device is provided with the synchronised recycling conveying belt in the bottom can prevent that lower floor's mud from adhering to bottom, high efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is folding oar stirrer among the figure, the 2nd, and magnetic field stirring area, the 3rd, precipitated and separated district, the 4th, demixing plate, the 5th, conveying belt.
Embodiment
Metal disposal plant in a kind of mud; Comprise interconnective magnetic field stirring area 2 and precipitated and separated district 3, be provided with the aeration agitation device in the said magnetic field stirring area 2, said whipping appts is three folding oar stirrers 1; Be provided with two demixing plates 4 in the said demixing zone 3; Said magnetic field stirring area 2 is 10-25 ° of angle with horizontal direction, and said magnetic field stirring area 2 is the high-frequency impulse field regions, and the percentage that upper, middle and lower-ranking takes up space of said demixing zone 3 is 80%, 13%, 7%; Described demixing plate 4 staggers successively and is 40-60 ° of angle with horizontal direction, and said bottom of device is provided with synchronised recycling conveying belt 5.
When handling mud, mud is to get into magnetic field stirring area 2 from interface, is raised by aeration agitation device aeration drum at this district's mud; Be stirred and the accelerate precipitation effect; Be beneficial to reconfiguring and layering of mud composition, be beneficial to the big sludge settling lower floor of density, especially contain the mud of heavy metal; When raising, stirring at aeration drum again under the effect of magnetic field, gravity, spin; Heavy metal atom or acceleration of ions move downward, and make to contain heavy metal atom or the more mud of ion and can reach the bottom more earlier, reach the stratified purpose of mud; Get into precipitated and separated district 3 then, separate in the layering outlet at last.
