Abstract

The utility model relating to a water, waste water or sewage treatment device provides a rotor drum type sewage filtering apparatus to realize reduction of production cost, convenient maintenance and energy conservation. The key design points of the utility model are as follows: the device comprises a bracket, wherein, the outer circular surface is provided with a rotor drum of a filter screen; the wheel spokes arranged at both sides of the rotor drum are propped up against the cross beam of the bracket through a bearing; the cross beam is a sewage intake pipe having the end parts provided with plugs; the far ends inside the two wheel spokes of the rotor drum are provided with a plurality of bailers, while one side of the baffle positioned above the water outlet of the water intake pipe arranged inside the rotor drum is provided with a guide plate used for supplying the bailers with water.

Description

A kind of rotary drum sewage filter device

Technical field

The utility model relates to the treatment unit of a kind of water, waste water or sewage.

Background technology

At present, the rotary drum water filtering device that uses in that sell on a kind of market and the water aquaculture, its constitutional features is: the rotary drum that filter screen is housed on outer garden face is bearing on the four rolling of support by the spoke at its two ends, the rotation of rotary drum is by being fixed on the electric motor on the support, mechanism such as speed reduction unit and gear thereof realizes, enters sewage in the rotary drum by water inlet pipe and is arranged on below the rotary drum that falls into rotation after the baffle plate buffering of water inlet pipe opening part by strainer filtering; In addition, there is the filter residue on the filter screen in also promising cleaning collection and the shower and the filter residue receiving tank that are provided with, and the sewage guiding tube etc. of getting rid of filter residue.The shortcoming of this device is: because its work under bad environment, ambient moisture is almost 100%, makes the driving mechanism of rotary drum, and as electric motor, mechanism's seriously corrodeds such as speed reduction unit not only increase maintenance cost, and the life-span of this mechanism is also low.In addition, this rotary drum is also rotated thereon by four fixed idler whell supportings on the support, and this just must make the very well-behaved rotary drum that just can make of outer garden face of spoke rotate steadily, but, because the external diameter of rotary drum is general bigger,, can strengthen cost again in order to satisfy higher processing precision.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of rotary drum sewage filter device: without electric motor, speed reduction unit and power drive mechanism thereof, by improving the drum structure of this device, it is driven by sewage current to be filtered as waterwheel, change the rotation connecting mode of rotary drum simultaneously,, reduce production costs so that make the structure of rotary drum sewage filter device simpler, convenient for maintaining, save energy.

Solution of the present utility model is as follows: a kind of rotary drum sewage filter device, comprise support, the garden face is provided with the rotary drum of filter screen etc. outside ... two spokes that it is characterized in that described rotary drum are bearing on the crossbeam of support by bearing, described crossbeam is the sewage water inlet pipe of end band shutoff, far-end in two spoke inboards of rotary drum is provided with a plurality of buckets, and baffle plate one side of the water inlet pipe water outlet top in rotary drum is provided with the flow deflector that supplies water to bucket.In order to guarantee the works better of filter screen, below filter screen, be provided with plastic wire, be provided with stainless (steel) wire in the above, for convenience of changeing of filter screen, the two ends of its filter screen overlap by velcro, and Bolt Connection is passed through at the two ends that overlay on the stainless (steel) wire above the filter screen.

Can find out that from above-mentioned solution the utility model has following beneficial effect: because the sewage that flows in the rotary drum enters the bucket that is located on the spoke by flow deflector, make rotary drum produce torque, rotatablely move thereby finish, so, this device has just saved transmission rigs such as electric motor, speed reduction unit and gear, make it simple in structure, reduced the trouble in the maintenance, production cost also reduces relatively; Again because the energy has also been saved in not working power; Also because its rotary drum changes the bearing support into, the cylindrical of spoke can be done not really well-behavedly, but can not influence the performance that operates steadily of rotary drum, therefore, because the change of the utility model rotary drum support pattern has also reduced production cost; Therefore the general life-span of the filter screen of filtration unit is lower, will often change, and the nylon buckles overlap joint is adopted at the two ends of filtering net of the present utility model, and it is very convenient to make it change filter screen, and the stainless (steel) wire of protection filter screen has also reduced trouble to operation by Bolt Connection.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model;

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: 1, support 2, the water inlet pipe 3 of making crossbeam, rotary drum 4, filter screen 5, bearing 6, bucket 7, baffle plate 8, flow deflector 9, shower 10, filter residue receiving tank 11, sewage guiding tube

Embodiment

Now in conjunction with the embodiments (accompanying drawing) the utility model is described in further detail: referring to Fig. 1 and Fig. 2.1 is support among the figure, its intermediary crossbeam 2 is the water inlet pipe of an end band shutoff, rotary drum 3 constitutes by two spokes that are arranged in parallel and for connecting a plurality of pitman shafts that spoke be arranged in parallel, central hole at described two spokes links by the external diameter of bearing 5 with water inlet pipe, garden in two spoke interior, distal end of rotary drum is provided with a plurality of buckets 6 on week, one side of the baffle plate 7 of the water inlet pipe water outlet top in rotary drum is provided with the flow deflector 8 that supplies water to bucket, between two spoke peripheries and described pitman shaft, lay the fixed plastic wire, on plastic wire, cover filter screen, its two ends overlap by nylon buckles, on filter screen, cover stainless (steel) wire, its two ends connect by bolt and nut, therefore described plastic wire and stainless (steel) wire not only play supporting role to filter screen but also shield; Above rotary drum, be parallel to the turning axle direction shower 9 that has a plurality of spray orifices is arranged, shower connects with the water source that certain pressure is arranged, be provided with filter residue receiving tank 10 above the water inlet pipe in rotary drum, one end of sewage guiding tube 11 be fixed on the filter residue receiving tank below, the shutoff that the other end passes water inlet pipe is stretched to outside the rotary drum.Present embodiment is work like this: when water inlet pipe 2 has effluent stream fashionable, its sewage is fallen into filter screen by the water inlet pipe outlet by baffle plate 7 buffering back major parts and discharges after filtration, part sewage is filled with bucket on the spoke of both sides through flow deflector 8, and rotary drum is produced a torque and makes it rotate to a direction.Because the continuous flow of sewage, the rotation that impels rotary drum not stop as waterwheel, when shower is connected with the water source of certain pressure, it will play cleanup action to filter screen, and the filter residue that sweeps away from filter screen falls into filter residue receiving tank 10 and through sewage guiding tube 11 discharges.
