Abstract
The invention relates to a kind of floccular apparatus and floccular industrial art in form of pulsating flow with variable direction and speed, which is composed with flocculator, sieve plate, vascellum for incoming stock and making the lay, rubber diaphragm, connecting rod of eccentric, and the eccentric. With the rotation of the eccentric, the invention makes the rubber diaphragm in the bottom of the flocculator moved joltily by the connecting rod of it; and it generates the pulsating flow with the variable direction and speed and up-down alternation; it can make floccular structure that is loose in previous, destroy and reconstitute into the combination with tight structure, low rate of water content and high speed of settlement; so it can improve the efficiency of solid-liquid separation. The advantages of this invention are as follows: it has simple equipment; it occupies smaller area; it needs lower investment; and it also has the high efficiency and low consumption. This invention is fit for the solid-liquid separation in many fields, such as chemical engineering, environmental protection, mining industry and so on.
Description
Technical field
The present invention relates to a kind of equipment for separating liquid from solid, particularly dynamic flow type flocculation plant and flocculation process.
Background technology
Can be divided into two classes at widely used flocculators in field such as chemical industry, environmental protection and mining industry.One class is the static mixing flocculator, and another kind of is dynamic mixed flocculation device.The former relies on as ad hoc structures such as helical form guiding devices in pipeline, makes suspended particulate mix, contact and flocculate; The latter is then flocculated by means of mechanical agitation makes the particle collision.The advantage of static flocculation device is that energy consumption is low, but because of mixing intensity is not enough, floc sedimentation then is difficult to carry out structural rearrangement once forming, thereby density is lower; Though dynamically flocculator consumes energy morely, flocculation rate is accelerated, and the fluid velocity gradient that causes has shear action to floc sedimentation, can make floc sedimentation carry out structural rearrangement and is able to closely knit.Simultaneously, the dynamic flocculator of traditional mechanical agitation type also exists the flocculation shortcoming that grain density is little, sinking speed is slow, and interrelated data has a detailed description in the book of " Separation of Solid and Liquid " (metallurgical industry publishing house, 1996).
Summary of the invention
The objective of the invention is to by provide a kind of equipment simple, take up an area of less, investment is little, treatment effeciency is high, energy consumption is low break-in speed change fluctuating flow formula flocculation plant and flocculation process, produce to reach that density is big, free settling and the easy floc sedimentation of dehydration, and then improve the purpose of solid-liquid separation effect.
The technical solution adopted for the present invention to solve the technical problems is: design a kind of break-in speed change fluctuating flow formula flocculation plant, this device is made up of flocculator, sieve plate, feed pipe, drainage conduit, diaphragm of rubber, connecting rod of eccentric wheel and eccentric wheel; Diaphragm of rubber is positioned at the bottom of flocculator, connects with eccentric wheel by connecting rod of eccentric wheel, and sieve plate is fixed on bottom in the flocculator.Wherein flocculator can be that two flocculators are unified into one group, also the even number flocculator can be unified into two groups.The flocculation process of this break-in speed change fluctuating flow formula flocculator is to utilize eccentric rotation, the diaphragm of rubber that drives the flocculator bottom by connecting rod of eccentric wheel do pitch mobile, in flocculator, form the break-in speed change, replace fluctuating flow up and down, make original loose floc sedimentation structure take place to destroy and reorganization, form the aggregation that structure is tight, water content is low and sedimentation is accelerated.Concrete flocculation process is: utilize water pump that the feed pipe of pending flocculated slurry from the flocculator top injected continuously, open eccentric wheel simultaneously, by connecting rod of eccentric wheel drive diaphragm of rubber do pitch mobile, in an eccentric period of motion, when diaphragm of rubber moves up, the space of hydroecium between compressed septum and sieve plate makes the water in the hydroecium rise through the sieve aperture of sieve plate; Diaphragm of rubber then move down then enlarges the volume of hydroecium, and the current on the sieve plate are descended, thus in flocculator, form the break-in speed change, alternately up and down fluctuating flow and quicken flocculation, the current after the flocculation are discharged through the drainage conduit of flocculator bottom.The structure of original floc sedimentation is destroyed and recombinated by break-in speed change fluctuating flow, the originally loosely organized floc sedimentation that contains large quantity of moisture becomes the less little flco of granularity under the shearing of fluctuating flow, these little flcos collide again and form big floc sedimentation, and it is tightr that loose structure originally then becomes; In addition, the effect of jolting of fluctuating flow can make the floc sedimentation of formation be squeezed and discharge the part moisture that wraps up in the floc sedimentation.
Break-in speed change fluctuating flow formula flocculation plant provided by the present invention and flocculation process, compare with traditional static state and dynamic mixed flocculation device, kept the shearing recombination of current on the one hand to floc sedimentation, increased fluctuating flow jolting and squeezing action simultaneously to floc sedimentation, and then tight, the heavy speed of acquisition structure is accelerated, the aggregation of moisture content reduction, effectively improved the efficient of Separation of Solid and Liquid, simultaneously this contrive equipment equipment simple, take up an area of less, investment is little, treatment effeciency is high, energy consumption is low, simple for process, have and promote and value.
The invention will be further described below in conjunction with drawings and Examples.
