Working principle:
It is first turned on inlet valve 10, so that sewage raw water is entered Rose Box 91 by water inlet pipe 8, then sewage raw water passes through passage 11, elastic force hose 1208 enters Material collecting box for harvesting 1206, while sewage raw water enters pretreater 1, filtering after the filtering of strainer 99 Solid particle out sinks under the action of its own gravity, and then solid particle enters under the guiding role of gib block 90 Passage 11, solid particle enters Material collecting box for harvesting 1206 by elastic force hose 1208 later, makes solid particle in Material collecting box for harvesting 1206 Inside aggregation, with the gradually aggregation of solid particle, the pressure that solid particle applies Material collecting box for harvesting 1206 is gradually increased, and makes to gather materials Case 1206 moves down, until conductive contact 1207 is contacted with conducting block 1204, signaling lamp 1209 is made to issue light, to work people Member is reminded, and then staff opens residual cake valve 1211, flows solid particle through scum pipe 1210 with a small amount of sewage raw water Out, staff is facilitated to focus on solid particle, solid particle releasing closes residual cake valve 1211 after finishing, during being somebody's turn to do, It converts flabellum 97 and pressure is applied to brush 98 under the action of holding out against 94 elastic force of spring, keep brush 98 and the left side of strainer 99 tight Contiguity touching, while sewage raw water pushes conversion flabellum 97 to rotate, conversion flabellum 97 is with 98 circular motion of brush, 98 pairs of brush filters The left side of net 99 is cleaned with water, and the solid particle adhered on 99 left side of strainer is brushed off, it is ensured that strainer 99 is able to maintain well Permeability, the sewage raw water after then filtering through strainer 99 is ejected on the inner surface of arc panel 5, makes the dynamic of sewage raw water It can reduce, the sewage raw water then to rebound impinges upon on the inner wall of pretreater 1 and on buffer board 42, and sewage raw water is dynamic later It can further decrease, be reduced newly into the sewage raw water of pretreater 1 to pretreatment under the action of 44 cushion effect of buffer spring The disturbance of the original sewage raw water in the inside of tower 1 facilitates high density organic layer 16 in sewage raw water, treatment sewage 17, low close It spends organic layer 18 to be layered, then sewage raw water is gradually assembled in the inside of pretreater 1, makes the liquid level of sewage raw water gradually It increases, during being somebody's turn to do, the immiscible component in sewage raw water is gradually layered under the action of density contrast, forms high density organic layer 16, treatment sewage 17, low-density organic layer 18, then low-density organic layer 18 provides a buoyancy to hollow floating circle 609, Move up hollow floating circle 609 with the rising of 18 liquid level of low-density organic layer, then hollow floating circle 609 passes through U-shaped drive rod 608, transmission rope 607 pull up cone seal plug 603, make cone seal plug 603 and conical through-hole 602 gradually It separates, gradually opens conical through-hole 602, treatment sewage 17 enters the processing of next link by outlet pipe 7 later, at this time The liquid level of low-density organic layer 18 peaks and keeps constant, with the extension of working time, high density organic layer 16 and the amount of low-density organic layer 18 gradually increase, move up the liquid level of high density organic layer 16 gradually, low-density is organic The upper liquid plane of layer 18 remains unchanged, and the lower liquid level of low-density organic layer 18 moves downwards, when floating 315 is immersed in completely When the inside of high density organic layer 16, the buoyancy that floating 315 is subject to reaches maximum value, and floating 315 passes through force rope at this time 314 pull up switching rope 313, and switching rope 313 is bent upwards and pulls the L-type arm of force 312, and the L-type arm of force 312 is with fixing axle 311 For the rotation of center axis, the pulling force being subject under the principle of lever to the L-type arm of force 312 is amplified, and then the L-type arm of force 312 is another One end is combined into the one upward lifting force of offer of positioning plate 306 by fastening movable part 308 and matching for T-type track 307, then fixed Position plate 306 moves up under the action of lifting force with cone rubber plug 305, separating pipe 304 is opened, high density has later Machine layer 16 enters the space of 201 lower section of demarcation plate by separating pipe 304, and then the liquid level of high density organic layer 16 gradually drops Low, until floating 315 is immersed in the inside for the treatment of sewage 17 completely, the buoyancy that floating 315 is subject at this time is minimum, then Positioning plate 306 pushes cone rubber plug 305 to move down under the action of 309 elastic force of pre-compressed spring, and separating pipe 304 is blocked, With the increase of 16 liquid level of high density organic layer in 201 lower cavity of demarcation plate, weighted spherical ball 203 is set to immerse high density organic Layer 16, weighted spherical ball 203 reduce the pulling force of traction rope 208, and then lifting piston 205 is in the case where jacking up the elastic force effect of spring 204 It is moved up with conductive touch panel 207, contacts conductive touch panel 207 with conductive bearing plate 209, then warning light 210 issues bright Light reminds staff, the height that staff will be separated by the cooperation of vomit pipe 19 and baiting valve 20 later Density organic layer 16 is released completely, and the buoyancy that then weighted spherical ball 203 is subject to disappears, and weighted spherical ball 203 is risen by the drawing of traction rope 208 Piston 205 drops, and lifting piston 205 is moved down with conductive touch panel 207, divides conductive touch panel 207 with conductive bearing plate 209 It opens, warning light 210 extinguishes, and when strain ball 1508 is immersed in completely in low-density organic layer 18, strain ball 1508 is subject to floating Power reduces, and the pulling force for straining 1508 pairs of ball strain ropes 1507 increases, and moves down lifting slider 1505 with plug 1506, will Seal pipe 1503, inlet opening 1502 are opened, and then low-density organic layer 18 is entered by perfusion tube 14 under the action of hydraulic and received Header 1301 makes to strain the buoyancy increase that ball 1508 is subject to, at this time until strain ball 1508 is completely immersed in treatment sewage 17 Lifting slider 1505 moves up under the action of 1504 elastic force of Packing spring with plug 1506, and seal pipe 1503 is sealed Firmly, with the raising of 1301 inside low-density organic layer of collecting box, 18 liquid level, floating plate 1308 will receive a upward buoyancy, Then floating plate 1308 moves up under the action of buoyancy with mandril 1307, and the top of mandril 1307 squeezes electroconductive elastic sheet 1305 end, 1305 bending deformation of electroconductive elastic sheet are simultaneously contacted with conductive plate 1303, so that warning lamp 1304 is shone, to staff It is reminded, the low-density organic layer that then staff will be separated by the cooperation of drain pipe 1311 and tapping valve 1312 18 release completely, and then floating plate 1308 moves down under the action of 1309 elastic force of reset spring with mandril 1307, later 1305 elasticity of electroconductive elastic sheet is restored and is separated with conductive plate 1303, and warning lamp 1304 is extinguished.
