The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: on the container 2 of tubbiness, clear water discharge pipe 14 is set, in container 2, be provided with separating tube 21, make and form sewage cavity 22 between separating tube 21 wall bodies and container 2 wall bodies, the bottom of separating tube 21 is fixedly installed on container 2 upper surfaces, on container 2 wall bodies, be provided with the sewage import 1 that is communicated with sewage cavity 22, in separating tube 21, be provided with scum pipe 12,21 top end opening portions are coated with screen pack 3 at separating tube, the opening at described screen pack 3 middle parts and scum pipe 12 top ends open communication are provided with the dirt that will hold back above the screen pack 3 and pour flusher in the scum pipe 12 in the container 2 above screen pack 3.

Described flusher comprises the support pipeline 7 that is erected at container 2 top ends, support on the pipeline 7 and be fixed with mount pad 23, be fixed with drive motors 9 on the mount pad 23, one rotating pipe 11 rotates to be plugged in the mount pad 23 and by drive motors 9 and drives its rotation, be connected with transverse strands in the bottom of rotating pipe 11 and be located at the shower 5 that the homocentric rays shape distributes that is above the screen pack 3, be equipped with plurality of nozzles 26 on the every shower 5, the top ends of offering described rotating pipe 11 is rotationally connected by the tube connector 8 that picks out on swivel joint 10 and the support pipeline 7.Described nozzle 26 is 20～30 ° angle with screen pack 3.

Be plugged with spoiler 4 in sewage cavity 22 top ends.Be provided with some supporting seats 24 at separating tube 21 inwalls, on supporting seat 24, be provided with and support filter screen 25, supporting the screen pack 3 that is provided with flexibility on the filter screen 25, the edge of screen pack 3 is upturned, on the screen pack above the supporting seat 24 3, be provided with ring holder 17, the outer end of ring holder 17 is provided with and compresses air bag 16, and the described air bag 16 that compresses is pressed on the edge part of screen pack 3 on separating tube 21 inwalls, and the described air bag 16 that compresses joins with gas supply device.

Putting on the shelf at separating tube 21 wall bodies is provided with mounting pipe 20, and the described air bag 16 that compresses joins with mounting pipe 20 outlet sides, and the inlet end of mounting pipe 20 joins by tracheae 19 and pressure regulator valve 18.

The plain boiled water that need to filter for a large amount of plain boiled waters that need to filter can be flow on the polyester screen pack 3 to uniform and stable, has inserted a plurality of spoilers 4 in container 2 interlayers from the sewage cavity 22 that advances sewage import 1 and enter container 2 and separating tube 21.After plain boiled water filtered through polyester screen pack 3, solid residue was stayed on the wire side, and clear water collects in the bottom of container 2, and discharged from clear water discharge pipe 14.In order to guarantee the filter efficiency of filter, solid residue must be eliminated out wire side timely and effectively.

This gravity filter adopts the rotary spray structure, and clean water flows into from water inlet 6 and supports in the pipeline 7, flows in the swivel joint 10 through tube connector 8 again.The shell of swivel joint 10 maintains static, and output shaft, steel pipe 10 and shower 5 link together, thereby has guaranteed that effectively clean water flows in the shower 5 smoothly from water inlet 6.In order to realize the rotation of shower 5, we adopt motor 9 to add the syndeton of swivel joint 10, and the central shaft of motor adopts hollow shaft.Rotating pipe 11 passes in hollow shaft, and shower 5, rotating pipe 11, swivel joint 10 link together, and when the central shaft of motor rotated, hollow shaft was by 11 rotations of key driven rotary pipeline, thus the rotation of realization shower 5.In order to guarantee to greatest extent solid residue to be cleared out of wire side, a plurality of V-type nozzles have been installed on the shower 5, and the wire side of the water outlet direction of nozzle and polyester screen pack 3 becomes 25 °.

Change polyester screen pack 3 for convenience, polyester screen pack 3 steadily is placed on stainless steel and supports on the filter screen 25, compresses air bag 16 and is fixed in the ring holder 17.Compressed air enters by pressure regulator valve 18, tracheae 19, mounting pipe 20 and compresses in the air bag 16.When source of the gas is opened, compress air bag 16 inflations, polyester screen pack 3 is compressed and is sealed on separating tube 21 inwalls.When source of the gas disconnected, the gas that compresses in the air bag 16 was excluded in pipeline, and therefore polyester screen pack 3 unclamps, and can freely change screen pack 3 this moment.Simply, convenient, can finish draping work without any need for professional's operation.

The utility model can fully filter paper plant's plain boiled water, and the plain boiled water of paper plant enters container 2 from water inlet, flow on the screen pack 3.After plain boiled water filtered through screen pack 3, solid residue was stayed the water that is rotated shower 5 ejections on the wire side then and is poured in blow-off pipe 12 roads, and clear water collects in the inside of container, and gets rid of from discharge outlet 13.The filter efficiency height of this filter can focus on the plain boiled water of big flow, and is simple in structure, change that screen pack is convenient, energy consumption is low.
