Abstract
The utility model discloses a shallow sand filter. The shallow sand filter adopts a vertical type structure formed by combining an upper hemispheric body with a lower hemispheric body and consists of the upper hemispheric body, the lower hemispheric body, an interception filter screen, a differential pressure controller, three-way valves, a water distributor, quartz sand, receivers and water caps. The shallow sand filter is characterized in that: the upper hemispheric body is provided with a water inlet, the lower hemispheric body is provided with a water outlet, the interception filter screen is arranged between the upper hemispheric body and the lower hemispheric body, the water inlet of the upper hemispheric body is provided with the water distributor, the water outlet of the lower hemispheric body is provided with the receivers, the water caps are connected onto the receivers, the quartz sand covers the water caps, and the differential pressure controller is arranged outside the lower hemispheric body. The shallow sand filter has the advantages of simple structure and convenience in maintenance, the energy consumption is lowered, and the production cost is lowered, so that the shallow sand filter is an ideal shallow sand filter.
Description
Technical field:
The utility model relates to sewage-treatment plant, especially a kind of shallow-layer sand filter.Be used for other water processing establishments such as smelting iron and steel factory, electric power, petrochemical industry, municipal works, food processing factory, papermaking, rubber leather manufactory.
Technical background:
Mainly use at a high speed and the middling speed filter at China's sewage filter device at present, these filter leaching material floor heights, bulky, complex structure, operation is got up, and power consumption is big, cost is high, cost performance is low.
Summary of the invention:
The technical problem that the utility model will solve is: provide a kind of when continuous filtration, remove impurity in the water through quartz sand filtration, utilize secondary cycle to purify waste water to greatest extent.
The technical scheme that the utility model filter is adopted is: said filtration device structure adopts vertical upper and lower hemispheres body to combine; Form by first spheroid, second spheroid, interception filter screen, differential pressure controller, triple valve, water-locator, quartz sand, gatherer, water cap; First spheroid is provided with a water inlet; Second spheroid is provided with a delivery port, is provided with an interception filter screen in addition in the middle of the upper and lower hemispheres body; The spheroid water inlet is provided with a water-locator, and delivery port is provided with gatherer, is connecting the water cap on the gatherer, is covered with quartz sand on the water cap; The spheroid outside is provided with differential pressure controller.
The utility model filter is natural physical characteristics such as pressure of utilizing water, the effect of adopting quartz sand filtration and water cap to collect, and vertical upper and lower hemispheres body, interception filter screen and shallow-layer filtrate combine; It has abandoned the multilayer filtrate, has reduced energy consumption, has simplified filter type; Adapt to various adverse circumstances, simple in structure, easy to maintenance, the life-span is long, has reached the effect of Separation of Solid and Liquid; Having reduced production cost, is a kind of desirable shallow-layer sand filter.
Description of drawings:
Fig. 1 is the structural representation of the utility model shallow-layer sand filter
The specific embodiment
Below in conjunction with accompanying drawing the utility model shallow-layer sand filter is described further.
As can beappreciated from fig. 1; Said shallow-layer sand filter structure adopts vertical upper and lower hemispheres body to combine; First spheroid 1 is provided with a water inlet 6 and a triple valve 5, is fixing water-locator 7 on the water inlet 6, and second spheroid 4 is provided with a delivery port 11; Fix gatherer 10 above, connecting water cap 9 on the gatherer 10; On gatherer 10 and water cap 9, be covered with quartz sand 8; Second spheroid 4 outsides also are provided with differential pressure controller 3, are provided with an interception filter screen 2 in the middle of first spheroid 1 and second spheroid 4.
The utility model filter utilizes some natural physical characteristics such as pressure of water, and the natural filtration of water distribution and quartz sand through water-locator is removed the dirt impurity in the water.Sewage gets into water inlet 6 from triple valve 5 during work, through evenly getting into inner chamber behind water-locator 7 water distributions, through interception filter screen 2 time, carries out coarse filtration, filters laggard entry cap 9 by quartz sand 8 essences then, is converged through delivery port 11 by gatherer 10 and flows out; After working after a while, the impurity on interception filter screen 2 and the quartz sand 9 increases, and chamber pressure raises; Surpass differential pressure setpoint; Differential pressure controller 3 sends signal, and the water inlet of triple valve 5 is closed sewage draining exit and opened, and clear water or filter back water get into gatherer 10 by delivery port 11; Get in the quartz sand 8 through water cap 9 again; Quartz sand 8 and the dirt impurity of tackling in the filter screen 2 are washed, and the dirt impurity that develops is flowed out through the sewage draining exit of triple valve 5 by water-locator 7 and water inlet 6 along current again, drops in the setting value until differential pressure.
