Abstract

The utility model relates to a sewage treatment device, and particularly belongs to filtering tanks. A multimedia filtering tank comprises a multimedia filtering tank body, a water inlet, a drain port, an exhaust hole, a transparent organic glass observing hole, a water level observing hole, a steel plate manhole, a water collecting plate, a filter material layer and a discharge port. The multimedia filtering tank is characterized in that an elbow of 90 degrees is connected to the water inlet; the rear end of the water inlet (2) can be additionally provided with a flange plate, a connecting pipe, the elbow and a water segregator in sequence; and an outlet of the water segregator is larger than the inlet and is in a shape of a loudspeaker. The multimedia filtering tank has the advantages that the existing multimedia filtering tank is changed a little, the water inflows uniformly and stably, the treatment effect is good, the backwashing capacity is improved, and the service period of the filter material is prolonged. The loudspeaker-shaped segregator is arranged, so that the water outlet area is increased and the impact of the inlet water to the filter material is avoided, therefore, the effects of filtering and precipitating are great, the water can not be mixed with the filter material, and as a result, the filtering efficiency of the filter material is greatly improved.

Description

The multi-medium filtering jar

Technical field

The utility model relates to sewage-treatment plant, especially belongs to filtering tank.

Background technology

Suspended solid is the solid matter of undissolved non-colloidal state in the water, and they can precipitate when condition is suitable.The main effect of multi-medium filtering jar is suspended material, the solid particle of removing in the water.Holding back suspended solid with filtering tank, is to hold back the weight difference of suspended solid front and back as weighing the foundation that filtering tank plays a role with filter medium.Existing multimedium biofiltration jar as shown in Figure 1, comprise tank body 1, water inlet 2, dewatering outlet 3, steam vent 4, transparent organic glass peep hole 5, water level peep hole 6, manhole 7, water collection sheet 8, filter material layer 9, floss hole 10, tank body 1 is fixed by tank body support 12, and steam vent 4 and transparent organic glass peep hole 5 all are positioned at the top of tank body 1.Personnel's turnover when manhole 7 is used for maintenance, sewage enters from water inlet 2, after handling by filtering layer 9, can remove bulky grain suspension in the water, thereby reduce the SDI value of water, satisfies the water quality requirement that deep layer purifies.

Because water inlet 2 is perpendicular to the inwall of tank body 1, water inlet is too concentrated with the contact area of filter material layer 9, cause filter material layer 9 local suffered impacts big, easily the sediment on the filter material layer surface of filtering-depositing below water inlet is broken up, cause filtrate and sediment to mix, influence the service life of filtrate.

Summary of the invention

The utility model purpose is to overcome the defective that above-mentioned multi-medium filtering jar exists, and provides a kind of and can guarantee that the sewage water inlet is even, stable, the multi-medium filtering jar that prolongs the service life of filtrate.

The technical scheme that the utility model adopts is a kind of multi-medium filtering jar, it comprises multi-medium filtering tank, water inlet, dewatering outlet, steam vent, transparent organic glass peep hole, water level peep hole, steel plate manhole, water collection sheet, filter material layer, floss hole, and its main points are to connect at water inlet the elbow of 90 degree.

The utility model is to improve on the basis of existing multi-medium filtering jar, the elbow that connects 90 degree at water inlet, because elbow has changed the flow direction of water, onesize water inlet pipe increases for filter material layer water outlet sectional area, the water outlet sectional area becomes a face identical with the elbow outlet from an original line in theory, thereby the impulse force of disperse water has been conducive to prolong service life of filtrate.

The water side that the utility model also can further be improved to elbow up.By allowing sewage overflow from the upper end, thereby the flow velocity that reduces water reduces the impulse force of water.

Increase flange plate, tube connector, elbow, water knockout drum in proper order in the water inlet rear end, water inlet is extended to the center of tank body, water knockout drum exports greater than import, is horn-like.Water inlet is extended to the center of tank body, like this water inlet to the impact of filter material layer centered by the tank body center to around diffusion, so its impulse ratio to filter material layer is more even.

By the effect of horn-like water knockout drum, further increase water-outlet area, avoided the impact of water inlet to filtrate, filtering-depositing is effective, can not mix with filtrate, has improved media filtration efficient greatly.The utility model advantage is existing multi-medium filtering jar is changed little, and water inlet is even, stable, and treatment effect is good, improves the backwash ability, prolongs the filtrate life cycle.

Wherein: 1 tank body, 2 water inlets, 21 tube connectors, 22 elbows, 23 water knockout drums, 24 flange plates, 3 dewatering outlets, 4 steam vents, 5 peep holes, 6 water level peep holes, 7 manholes, 8 water collection sheets, 9 filter material layers, 10 floss holes, 11 mud holes, 12 tank body supports.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, can makes the professional and technical personnel more understand the utility model, following embodiment is made amendment, it all is possible adding and replacing, and does not all exceed protection domain of the present utility model.

Embodiment 1, as shown in Figure 2, a kind of multi-medium filtering jar, identical with existing multi-medium filtering jar, comprise multi-medium filtering tank 1, water inlet 2, dewatering outlet 3, steam vent 4, transparent organic glass peep hole 5, water level peep hole 6, steel plate manhole 7, water collection sheet 8, filter material layer 9, floss hole 10, tank body 1 is fixed by tank body support 12, on this basis, connects the elbow 22 of 90 degree at water inlet 2.Owing to connect the flow direction that 90 elbows of spending have changed water at water inlet 2, onesize water inlet pipe increases for filter material layer 9 water outlet sectional areas, the water outlet sectional area becomes a face identical with the elbow outlet from an original line in theory, thereby the impulse force of disperse water has been conducive to prolong service life of filtrate.It is same as the prior art that all the other do not state part.

Embodiment 2, as shown in Figure 3, on the basis of embodiment 1 with the water side of elbow 22 up.It is identical with last example that all the other do not state part.

Embodiment 3, as shown in Figure 4, increase flange plate 24, tube connector 21, elbow 22, water knockout drum 23 in proper order in water inlet 2 rear ends, and water inlet is extended to the center of tank body 1, and water knockout drum 23 outlets are horn-like greater than import.Water inlet is incorporated into the tank body centre, and makes into that water overflows from water knockout drum 23 upper ends, increase water-outlet area, avoided the impact of water inlet to filtrate, filtering-depositing is effective, prolongs the filtrate life cycle.It is identical with embodiment 2 that all the other do not state part.
