Abstract
The utility model discloses a fully automatic sand filter, which comprises a central pipe and a water distributor. The central pipe is provided with an internal thread, the upper end of the central pipe is connected with the water distributor, and the trapezoidal distributor includes eight branch distributors in annular distribution. The fully automatic sand filter solves the problems of poor filtering capacity, difficulty in operation and maintenance, high energy consumption and the like of traditional sand filter equipment, solves the problems of high pressure, high energy consumption and the like while guaranteeing enhanced filtering and purification effects, cost is reduced evidently, and the fully automatic sand filter is low in failure rate and convenient in mounting, operation and maintenance, and is more suitable for popularization and application.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of full-automatic sand filter, belongs to water treatment preliminary treatment prefiltration technical field.
Background technology
Sand filter mainly is a kind of equipment that utilizes sand to filter sewage, compressed air is discharged by special valve from the central tube bottom, produce negative pressure in its bottom in the process of arranging on the air-flow, carry the casting bed of dirt like this and taken out of, in the process that rises, finish and wash by rubbing with the hands and separate, when outreaching, sewage flows out from the upper left tubule of drainpipe, drops in the process of casting bed at sand grains, is cleaned by a spot of rising water purification again, rinse water and sewage are discharged together, thereby reach the function of purifying waste water.
Traditional sand filter adopts water inlet suitable for reading, the mode of end opening water outlet, and filtration is not strong, and pressure height, power consumption also need regularly backwash, safeguard also inconvenient.
The utility model content
The utility model provides a kind of full-automatic sand filter, and is not strong to solve existing sand filter filtration, the problem of pressure height, power consumption and regularly cleaning, maintenance inconvenience.
For solving above technical problem, the technical solution adopted in the utility model is: a kind of full-automatic sand filter, comprise central tube, water-locator, and it is characterized in that: there is screw thread described central tube inside, and its upper end is connected with water-locator; Described water-locator is trapezoidal water-locator totally 8 branches that distribute ringwise.
A little less than the filter capacity of the utility model at traditional sand filter equipment, the Operation and Maintenance difficulty, problems such as it is big to consume energy, can guarantee under the strong prerequisite of filtration, purification effect, solved pressure height, power consumption problem such as big, significantly reduced cost, fault rate is low, fitting operation is easy to maintenance, more helps applying.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, water inlet; 2, water-locator; 3, filter bed; 4, sand-washing device; 5, filtrate (liquid; 6, central tube; 7, outlet of sewer; 8, air lift.
The specific embodiment
As shown in Figure 1, the utility model mainly comprises: water inlet 1, water-locator 2, filter bed 3, sand-washing device 4, filtrate (liquid 5, central tube 6, outlet of sewer 7, air lift 8.
There is screw thread central tube 6 inside, and water enters central tube 6 by water-locator 2, and sand enters central tube 6 by the lower end, and sewage flows out from outlet of sewer 7 then, and clean sand flow is gone into filter bed, continuous-flow.Central tube 6 is the centers that connect.
Water-locator 2 is connected with central tube 6, is trapezoidal, annular spread, and totally eight branches, water is entered by water-locator 2.
Produce the water running flow process: the equipment water inlet is from water inlet 1 water inlet, and water-locator 2 outflows through the lower end enter filter bed 3, filter dirt and are held back by casting bed, and clear water flows out from upper right quarter filtrate (liquid 5.
The dirt cleaning process: compressed air is discharged from central tube 6 bottoms by special valve, produce negative pressure in its bottom in the process of arranging on the air-flow, carrying the casting bed of dirt is like this taken out of, in the process that rises, finish and wash by rubbing with the hands and separate, when outreaching, sewage flows out from outlet of sewer 7, drops in the process of casting bed at sand grains, cleaned by a spot of rising water purification again, rinse water and sewage are discharged together.4 is that sand-washing device, 8 is air lift.Backsurging principle mainly is to realize recoil by air lift 8, and sand is sent in the central tube 6, reduces the influence of pressure.
The utility model can be finished backwash under the state that does not need to shut down, the process of air purge, and not disturbing mutually, and this process continues, and round-the-clock.
Claims (2)
1. a full-automatic sand filter comprises central tube, water-locator, it is characterized in that: there is screw thread described central tube inside, and its upper end is connected with water-locator; Described water-locator is trapezoidal distribution ringwise.
2. full-automatic sand filter according to claim 1 is characterized in that: described water-locator is totally 8 branches.
