Abstract
The utility model relates to a dirt separating device, in particular to a rotational flow dirt separator applied to urban water supply, industrial pipelines and industrial and agricultural production. The dirt separator comprises a tank body, cylindrical screen cloth, a water inlet pipe, a manhole and a drain outlet, wherein the inside of the tank body is communicated with the cylindrical screen cloth of a water outlet pipe; the water inlet pipe enters along the tangent direction of the tank body; the manhole is arranged on one side of the tank body; the drain outlet is arranged at the lower end of the tank body; the water inlet pipe and the water outlet pipe are provided with bypass pipelines; and a differential pressure alarm device is arranged between the water inlet pipe and the water outlet pipe. The rotational flow dirt separator has the advantages of simple and reasonable structure, continuous running of equipment, normal operation of a pipe network, time saving and labor saving during backwash cleaning, high working efficiency and the like.
Description
Technical field
The present invention relates to a kind of decontamination apparatus, a kind of specifically spiral-flow type dirt separator that is applied to urban water supply, industrial pipeline and industrial and agricultural production.
Background technology
The eddy flow dirt separator is to be used for removing dirt in the fluid and a kind of decontamination apparatus of impurity.As everyone knows, newly-built pipe network often leaves a large amount of dirts and impurity at initial operating stage in the pipeline, and under flow regime, these dirts and impurity have very big impulsive force, can produce general decontamination apparatus to destroy.And the scrubbing of eddy flow dirt separator is reliable, efficient is high, removes contamination conveniently, and circulating pump is not closed in the blowdown that can be in operation of eddy flow dirt separator when both removing contamination, open sewage draining valve, discharges dirt and impurity.
Structurally also there is unreasonable place in above-mentioned eddy flow dirt separator, be in particular in: ducted part floating thing and suspension can stop up outlet pipe import screen cloth under the effect of water outlet pressure reduction, when obstruction is serious, have to close the circulating pump cleaning, the labor cleaning is time-consuming to take a lot of work, so just cause the dirt separator can not continuous operation, influence the normal operation and the operating efficiency of pipe network.
Summary of the invention
The objective of the invention is to provide a kind of simple and reasonable, equipment can continuous operation, can not close circulating pump because the effluent pipe mouth screen cloth stops up, and influences pipe network normally to move, and utilize the backwash cleaning time saving and energy saving, the spiral-flow type dirt separator of high efficiency.
The object of the present invention is achieved like this, the water inlet pipe that this dirt separator comprises the tubular screen cloth that is communicated with outlet pipe in the tank body, tank body, enters along the tank body tangential direction, be arranged on the manhole of tank body one side, be arranged on the sewage draining exit of tank body lower end, between described water inlet pipe and outlet pipe, set up a bypass pipe road, the pressure reduction alarm is housed between water inlet pipe and outlet pipe.
Be respectively arranged with stop valve on described water inlet pipe, outlet pipe and the bypass line.
The present invention has the following advantages:
1, in order to solve the problem that floating thing and suspension stop up the effluent pipe mouth screen cloth, the present invention has adopted on the eddy flow dirt separator and has installed bypass line additional, import and export the installation stop valve at bypass line, eddy flow dirt separator, the eddy flow dirt separator installs the pressure reduction alarm additional between importing and exporting; Pressure reduction alarm when dirt separator stops up, we close eddy flow dirt separator inlet shutoff valve, open bypass line stop valve and sewage draining exit valve, give piped water supply earlier, utilize the eddy flow dirt separator to go out saliva carries out backwash to the effluent pipe mouth screen cloth technical scheme by bypass line.
2, this name dirt separator can continuous operation, no longer occurs closing circulating pump because of the effluent pipe mouth screen cloth stops up, and influences the phenomenon of the normal operation of pipe network; The backwash cleaning is time saving and energy saving, high efficiency.

Fig. 2 is an A-A cutaway view among Fig. 1 of the present invention.
Fig. 3 is an A place amplification assumption diagram among Fig. 1 of the present invention.
The specific embodiment
Shown in accompanying drawing: the water inlet pipe 4 that this dirt separator comprises the tubular screen cloth 3 of tank body 1, tank body 1 internal communication outlet pipe 2, enters along tank body 1 tangential direction, be arranged on the manhole 5 of tank body 1 one sides, be arranged on the sewage draining exit 6 of tank body 1 lower end, set up a bypass pipe road 7 at described water inlet pipe 4 and outlet pipe 2, between water inlet pipe 4 and outlet pipe 2, pressure reduction alarm 8 is housed.
Be respectively arranged with stop valve 9 on described water inlet pipe 4, outlet pipe 2 and the bypass line 7.
Operation principle:
The eddy flow dirt separator is a principle of utilizing centrifugal sedimentation.When the fluid that is mixed with dirt and impurity enters tank body 1 from eddy flow dirt separator inlet with tangential direction with certain pressure, produce the strong strong rotary rotational flow of three-dimensional ellipse and flow.Owing to have density contrast between dirt and impurity and the fluid, under effects such as centrifugal force, centripetal force, buoyancy, fluid resistance, dirt and impurity are pressed the helical trajectory backspin to the bottom, deposit and are discharged by sewage draining exit 6.Fluid in be formed centrally inside spin liquid and flow to motion, discharge by outlet pipe 4.
During pipe network operation, the eddy flow dirt separator is opened into and out of pipe (mouth) stop valve, and the bypass line stop valve is closed, the dirt separator operate as normal.Dirt in the pipeline and impurity backspin under effects such as centrifugal force, centripetal force, buoyancy, fluid resistance deposits and is discharged by sewage draining exit to the bottom; Ducted part floating thing and suspension are being attached under the effect of water outlet pressure reduction on the eddy flow dirt separator outlet pipe import screen cloth; Along with increasing gradually of dirt impurity, pollution has been stopped up screen cloth gradually, and eddy flow dirt separator inlet outlet pressure differential increases gradually, when pressure reduction reaches certain value, and the pressure reduction alarm equipment alarm; Close eddy flow dirt separator inlet shutoff valve, open the bypass line stop valve, give pipe network water supply earlier by bypass line, equipment runs well.Because eddy flow dirt separator inlet shutoff valve is closed, eddy flow dirt separator import hydraulic pressure descends near atmospheric pressure; Dirt separator outlet hydraulic pressure is pipe network water pressure; Water flows back to tank body by outlet pipe, and screen cloth is formed backwash.And because pressure when screen cloth both sides pressure reduction is greater than normal operation during backwash, the pollution on the filter screen can very fast quilt under recoil pressure washes away by sewage draining exit and gets rid of tank body.Behind the flushing certain hour; Close the bypass line stop valve, open eddy flow dirt separator inlet shutoff valve.The eddy flow dirt separator is replied operate as normal.
