Abstract
The utility model discloses a sedimentation tank adopting a pump to feed dense slurry for washing, which belongs to the technical field of cleaning of the dense slurry at a sedimentation layer of the sedimentation tank and aims at overcoming the disadvantages that the quantity of washing liquid is large and the liquid content of the collected slurry is high when the present sedimentation tank is used for collecting sediments. The sedimentation tank comprises a sedimentation tank, a dense liquid pipe and a valve thereof, and a clear liquid pipe and a valve thereof; the sedimentation tank is longitudinally divided into two or more airtight sedimentation branch chambers; each sedimentation branch chamber is respectively provided with a dense liquid branch pipe, a clear liquid branch pipe and a ventilated balancing pipe; the dense liquid branch pipe, the clear liquid branch pipe and the ventilated balancing pipe are respectively provided with valves; the sedimentation tank is further provided with a dense slurry pump and a dense slurry drainage pipe with a valve; the dense slurry pump is respectively communicated with the dense liquid end and the clear liquid end of each sedimentation branch chamber by a dense slurry main pipe and a dense slurry branch pipe with a valve, and the dense slurry drainage pipe is respectively communicated with the dense slurry main pipe at the positive/negative-pressure ends of the pump and the bottom part of each sedimentation branch chamber. The utility model is suitable for various sedimentation tanks.
Description
Technical field
The utility model relates to a kind of underflow Removal Technology of sedimentation basin sedimentary deposit, particularly relates to a kind of sedimentation basin of pumping underflow flushing.
Background technology
In present a lot of industries; as agricultural byproducts processing, food industry, chemical chemical fertilizer industry, pharmaceuticals industry, sewage disposal or the like, usually having will be suspension or mixing but non-ly be dissolved in the technological process granular in the liquid, that powdery solid isolates out from liquid.Generally, the liquid of above-mentioned indication is water in very big part technological process.Because the outstanding solid that mixes in liquid is very tiny, majority is the material that easily absorbs water simultaneously, and their proportion approaches water very much, if adopt filtration method or centrifugal concentration method, all exists processing cost high, the problem that effect is relatively poor.So in a lot of these technological processes, all adopt sedimentation basin as the preceding road process program that carries out Separation of Solid and Liquid.That is to say that sedimentation basin is because its technology is easy, advantages such as operating cost is low, effect stability are occupied important position in the solid-liquid separation process flow process of at present a lot of industries.Through years of development, every technology of sedimentation basin all improves a lot, and indexs such as particle residual quantity, precipitation density, sedimentary deposit formation time are investigated from surfaceloadingrate, clear liquid, can say in mind, sedimentation basin all is FA at present.But through investigation, present sedimentation basin just adopts quck-opening valve to make liquid moment of slow flow become to flow fast very much and washes away sedimentary deposit in carrying out the deposit collection process; Have flush liquid scouring force deficiency, fluid volume is bigger than normal, and the underflow liquid content after the collection is higher, and taking off liquid technology for the road, back has increased deficiencies such as load.
Summary of the invention
The purpose of this utility model provides the sedimentation basin of a kind of pumping underflow flushing, overcomes present sedimentation basin when collecting deposit, and it is bigger than normal to wash away liquid measure, the underflow liquid content after the collection is higher wait not enough.
The utility model is achieved by following technical proposals.
The utility model comprises sedimentation basin, dope pipe and valve, clear liquid pipe and valve, and described sedimentation basin is by vertically being divided into the airtight precipitation locellus more than two or two, and described precipitation locellus is all established dope arm, clear liquid arm and the ventilative balance pipe that valve is housed; Be provided with underflow pump, described underflow pump is communicated with the dope end and the clear liquid end of described precipitation locellus respectively by underflow house steward, underflow arm that valve is housed, if the underflow delivery pipe of valve is housed, described underflow delivery pipe is communicated with the positive and negative pressure side underflow house steward of pump and the bottom of described precipitation locellus respectively.The essence of this programme is that sedimentation basin is divided into the less precipitation locellus of volume, in washing away sedimental process, allows each precipitation locellus wash away respectively, makes and washes away liquid measure and significantly reduce.Simultaneously, use repeatedly, make the underflow concentration after washing away higher.
The utility model is not corrosive if the dope in the sedimentation basin does not contain when implementing, and then all pipelines can adopt the comparatively ripe coating steel pipe of manufacturing and mounting process, and equipped valve can adopt the gate valve of cast iron housing copper core.If the dope in the sedimentation basin contains be corrosive, then all pipelines should adopt the anti-rot plastic pipe, and equipped valve also should adopt the anti-rot plastic ball valve.
Against existing technologies, the beneficial effects of the utility model are:
Reduce and wash away fluid volume, got high and washed away the concentration of underflow afterwards, alleviated the load that back road takes off liquid technology, say on the whole, reduced the cost of Separation of Solid and Liquid.
Description of drawings
Fig. 1 is the utility model flow process schematic diagram, and Fig. 2 is the utility model underflow flushing system axonometric drawing.Among the figure: 1, precipitation locellus, 2, the dope arm, 3, the clear liquid arm, 4, ventilative balance pipe, 5, underflow pump, 6, underflow house steward, 7 underflow arms, 8, the underflow delivery pipe.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and the specific embodiment.
When sedimentation basin by by after vertically being divided into several locellus, each locellus is actual to be exactly a little sedimentation basin, at this moment opens the valve of ventilative balance pipe 4, adjusts the flow of dope arm 2 and clear liquid arm 3, allows dope precipitate in precipitation locellus 1.When the sedimentary deposit on the depositional plane is enough thick should wash the time, only stay the liquid of a precipitation locellus, the clear liquid of remaining precipitation locellus is all under the situation of closing all dope arms 2, by 3 emptying of clear liquid arm.Start underflow pump 3, close the valve of ventilative balance pipe 4, at first the precipitation locellus that only has liquid is carried out the liquid internal flow at high speed, towards clear sedimentary deposit, liquid becomes underflow.Then, close the valve on the import underflow arm of this locellus earlier, open the valve on the import underflow arm of a back locellus, regulate the keying of the ventilative balance pipe of two precipitation locellus successively, after underflow all enters behind locellus, close the valve on the underflow arm of of previous locellus, open the valve on the outlet underflow arm of a back locellus, make a back branch chamber interior underflow flow at high speed, towards clear sedimentary deposit.So the precipitation locellus is carried out one by one, after sedimentary deposit all dashed clearly in each precipitation locellus, last underflow was discharged by underflow delivery pipe 8.
