Description
Technical field
The present invention relates to a kind of solid-liquid separator, belong to environmentally friendly water treatment field, especially a kind of slanted screen solid-liquid separator and
Its application method, separation of solid and liquid and collection especially suitable for livestock and poultry and aquaculture excrement.
Background technology
In recent years, it as China is intensive, the fast development of scale animal and poultry cultivation and culture fishery, produces a large amount of
The excretas such as excrement, become the main force of agricultural non-point source pollution, if be not pocessed to it, will be caused to ecological environment sternly
The pollution of weight obtains a large amount of organic fertilizer as can recycling contained in these excretas, can also be that raiser open up a cause
Fu Xinlu.But to these excretas are become organic fertilizer, it is necessary to be divided excreta existing for these solid-liquid mixings
From processing, when the solid-liquid separating equipment generally used at present is separated by solid-liquid separation, fecal sewage mixture is usually by delivery pump elder generation
It is sent into surge chamber or spill tank, then overflows and comes and along the draining sieve plate of nearly tablet setting to flowing down from surge chamber or spill tank
It is dynamic, large quantity of moisture is had in solidliquid mixture flow process and is flowed out from the fine crack of draining sieve plate, and then water content is opposite
Lower solid matter, which is separated, to be further processed.
The relatively low solid matter separation of general water content is transported out by screw rod conveyor, such separation of solid and liquid
Power is needed, the relatively small number of sewage of low concentration of solid content is not suitable for.Common separation of solid and liquid sieve bend is the cylinder lieed down
The bodily form sieves bucket, is easy to that solid is blended or battered down when being separated by solid-liquid separation, increases the difficulty of separation of solid and liquid, reduce and shut off
Quantity.And it lies down the waste residue that cylindrical solid-liquid separator is isolated to be easy to be deposited in cylinder, be not easily taken out, at later collection
Manage problem the more.
Invention content
The present invention is directed to the problem of separation of solid and liquid facilities and equipment for lacking low concentration liquid dung in scale farm, by changing
The form and set-up mode for becoming filter cylinder transform filter cylinder as nearly cone by cylinder, and horizontally disposed are transform as by common
Obliquely or vertically it is arranged, spatially realizes the greater area of solid matter that shuts off of the same area, realize the nature of waste
It concentrates, reduces collection processing problem.The configuration of the present invention is simple, highly practical, when work, itself need not consume power, be water
The device, method of production cultivation collecting dung and separation of solid and liquid, the efficient trapped particles object of energy, especially under the conditions of high-density breeding, excrement
Just collection separation equipment advantageously accounts for aquaculture pollution of area source problem.
The present invention is achieved through the following technical solutions：A kind of slanted screen solid-liquid separator and its application method include holder, tiltedly
