Description

A kind of rotary continuous sewage filter device

Technical field

The utility model relates to a kind of water, waste water or sewage-treatment plant.

Background technology

A kind of known rotary sewage filter device, as the patent No. is that 03284668.1 name is called a kind of rotary drum sewage filter device, it comprises that an end that is supported on the support has the sewage water inlet pipe of shutoff, it links to each other with the rotary drum that two spokes and a plurality of support bar that is arranged in parallel in the spoke far-end constitute by bearing, be positioned at the rotary drum top wash tub pipe that is furnished with a plurality of spray orifices in parallel, be positioned at the filter residue feeder of the corresponding layout in upper end of rotary drum inside with wash tub pipe, its lower end links to each other with an end of sewage guiding tube, sewage guiding tube enters sewage water inlet pipe and draws by its shutoff, far-end in two spoke inboards of rotary drum is provided with a plurality of buckets, one side of the sewage water inlet pipe delivery port top plate washer in rotary drum is provided with the deflector that supplies water to bucket, elder generation spreads one deck plastic wire and fixes by velcro on the periphery of rotary drum, establish filter screen above the plastic wire, topped and pass through bolting above the filter screen with stainless (steel) wire.The shortcoming of technique scheme is: because filter screen is a plane, its dirt that filters out is difficult for taking to the rotary drum top, therefore be difficult for discharging, also owing on described filter screen, have plastic wire and stainless (steel) wire, the resistance of flushing filter screen is strengthened, dirt on its filter screen is difficult for all washing out, often stop up, the 3rd, owing to the plastic wire below filter screen is fixed by velcro, because its bonding strength is low, velcro easily slides when work, the span of adding between the support bar that supports plastic wire is big, makes plastic wire become pocket shape, its result, the one, the resistance when having increased the filter screen flushing, the 2nd, increased the weight of the wearing and tearing of filter screen because rotary drum whenever turns around filter screen will and plastic wire and stainless (steel) wire between produce the displacement friction, so the filter screen quick abrasion.

Summary of the invention

The purpose of this utility model is to provide a kind of rotary continuous sewage filter device in order to overcome above-mentioned the deficiencies in the prior art, change the rotational structure of prior art, make it simple in structure and produce big torque, design new filter structure and reduce the strainer filtering resistance, increase the ability of removing dirt, prolong the service life of filter screen.

The utility model solution is as follows:

A kind of rotary continuous sewage filter device, comprise that an end that is supported on the support has the sewage water inlet pipe of shutoff, its by bearing with link to each other with the rotary drum that a plurality of support bars that are arranged in parallel in the spoke far-end constitute by two spokes, be positioned at the rotary drum top wash tub pipe that is furnished with a plurality of spray orifices in parallel, be positioned at the filter residue feeder of the corresponding layout of rotary drum inner upper with wash tub pipe, its lower end links to each other with an end of sewage guiding tube, sewage guiding tube enters sewage water inlet pipe and draws by its shutoff, it is characterized in that: on a plurality of support bars of rotary drum and spoke periphery, be provided with grid, on the muscle in length and breadth of the periphery of grid, be pasted with filter screen, sewage water inlet pipe bottom in rotary drum has a plurality of delivery ports vertically, delivery port of its right-hand member connects a L shaped outlet pipe, the other end of outlet pipe is near grid and connect an impact water pipe parallel with sewage water inlet pipe, its underpart has a plurality of impacts mouth of a river, and all impact the center line at the mouth of a river and the cylindrical of filter screen and the tangent line angle at impact center line intersection point place, the mouth of a river and acutangulate.One be positioned at sewage water inlet pipe and with the corresponding pin of its internal diameter, its end links to each other with the pull bar that passes the sewage water inlet pipe shutoff.

By above-mentioned solution as can be seen, owing on spoke periphery and a plurality of support bar, certain thickness grid is housed, periphery at grid is pasted filter screen on the muscle in length and breadth, because grid has certain thickness, its rigidity is big, not yielding, filter screen is again firm being bonded on the grid, do not produce and slide or relax, faint friction only takes place with the dirt that deposits in filter screen at work, and therefore, can be multiplied its service life, as the filter screen of prior art, will renew in one month, and this solution filter screen did not need to change in 1 year yet; Because the top and bottom of filter screen do not have plastic wire and stainless (steel) wire, significantly reduced the resistance that sewage water filtration produced again, therefore the dirt that accumulates in the grid washes out easily, does not have the filter screen phenomenon that is blocked; Also, so just can preferably dirt be taken to the rotary drum top, and discharge by flushing because the filter screen lattice have certain thickness; Sewage water inlet pipe bottom in this external rotary drum has a plurality of delivery ports, and at the L type outlet pipe of terminal of a delivery port connection of right-hand member near grid, connect the impact water pipe that there is a plurality of impacts mouth of a river an its underpart parallel with sewage water inlet pipe in the outlet pipe end, and the tangent line angle at the water (flow) direction at its impact mouth of a river and the intersection point place of filter screen cylindrical and water (flow) direction acutangulates, the current that this structure is gone out the impact water pipe hit on grid, the rotating torque of rotary drum will be increased greatly, overcome prior art because the too small shortcoming that makes the torque deficiency of bucket, if in sewage water inlet pipe, place a pin that adapts with internal diameter, its end links to each other with the mast that passes the sewage water inlet pipe shutoff, when drawing or during pull bar, adjust the quantity of pin shutoff sewage water inlet pipe bottom delivery port, can adjust from impacting water pipe and go out the flow velocity of water to adjust the rotating speed of rotary drum.
