In order to improve the liquid flow on the periphery of the guide cylinder 24, the water guide wheel 31 is installed on the outer side of the upper end of the guide cylinder 24, the lower portion of the water guide wheel 31 is immersed into the treatment liquid in the treatment tank II 2 and rotates towards the inner side of the guide cylinder 24, the water flow circulation flow can be further promoted through the auxiliary rotation of the water guide wheel 31 rotating actively, part of treatment liquid on the upper side of the floc collecting cover 23 is concentrated into the guide cylinder 24, then under the action of the foaming device, the floc collecting efficiency in the floc collecting cylinder 32 is accelerated, and the fiber impurities are convenient to be collected and treated.

In order to improve the impurity treatment efficiency in the flocculation cylinder 32, a lower water retaining edge 26 which is bent downwards and outwards is formed at the lower end of the guide cylinder 24, an aeration cylinder 27 is arranged at the inner side of the lower water retaining edge 26, the aeration cylinder 27 is in a cylindrical structure which is gradually reduced upwards and is opposite to a guide cover 33 at the lower end of the flocculation cylinder 32, a second filter screen 28 is arranged at the inner side of the aeration cylinder 27, foaming devices are arranged at the two ends of the aeration cylinder 27 and are opposite to the two sides of the second filter screen 28, so that bubbles sprayed out of the foaming devices can directly enter the flocculation cylinder 32 along the flow guide direction of the aeration cylinder 27, and the impurity removal effect is improved;

the foaming device is including the bubble pipe 29 and the bubble pipe 30 that are located two 28 upper and lower both sides of filter screen respectively, all install the nozzle mouth on each bubble pipe, and with the direction of this air jet towards two 28 filter screens, in the injection process, can clear up two 28 surface adhesion's of filter screen impurity, and along with the mutual impact who foams of upper and lower both sides strikes the stirring to the treatment liquid of this position, make wherein the flocculent fibre that is mingles with can be twined each other more concentratedly, thereby form bigger fibrous impurity tissue, thereby be convenient for concentrate the clearance to it.

In order to more conveniently clean impurities in the floc collecting cylinder 32, a filter plate 35 is arranged in the floc collecting cylinder 32, the filter plate 35 consists of two parts and is hinged at the middle joint, and the middle position can be driven to be downwards sunken by approaching the two ends of the filter plate 35 under the action of gravity, so that the floc impurities in the floc collecting cylinder 32 are guided towards the two sides; because the position of filter 35 is in the position below the liquid level of treatment fluid, when the upset of filter 35, will upwards remove by cotton-shaped impurity under the effect of buoyancy to can partly remove the position to the filter 35 upper strata, thereby with the separation of cotton-shaped impurity, be convenient for handle impurity.

In order to further make things convenient for the centralized processing of a collection wadding section of thick bamboo 32 middle impurity, can be located filter 35 both sides at a collection wadding section of thick bamboo 32 and lean on the upper position and set up passageway 39, can supply the cotton-like thing to discharge, and set up collection wadding groove 38 in the both sides of a collection wadding section of thick bamboo 32, collection wadding groove 38 is through this passageway 39 and collection wadding section of thick bamboo 32 inner chamber UNICOM, thereby make the cotton-like impurity of upwards discharging from filter 35 both sides can be entered into collection wadding groove 38 by the water conservancy diversion and work as well, collection wadding groove 38 then can adopt the detachable structure, can carry out convenient change and cleanness to it in the.

The height of this collection wadding groove 38 is less than the height of baffle 4, and collection wadding groove 38 submerges in the middle of the treatment fluid promptly to set up a plurality of filtration pores, make collection wadding groove 38 have the treatment fluid in the middle, thereby make collection wadding groove 38 the flocculent impurity in the middle still can relative activity, avoid it to gather adhesion passageway 39 and produce the jam with collection wadding groove 38.

The movement of the filter plate 35 can be driven by the telescopic rod 37, the filter plate 35 is flush with the lower edge of the channel 39, the middle of the filter plate 35 is hinged, the left end and the right end of the filter plate 35 are respectively hinged with a water baffle 34, the water baffle 34 is upward vertical and can relatively slide in a reciprocating manner through a slide bar 36, when the water baffle 34 is far away from the opening of the channel 39, the filter plate 35 is separated from the inner wall of the wadding collecting cylinder 32, and the channel 39 is opened; when the water baffle 34 slides towards two sides, the water baffle 34 corresponds to the channel 39, and can push part of floating impurities towards two sides, enter the flocculation collecting groove 38 and be collected in a centralized manner, and then continuously move the water baffle 34 to close the channel 39, so that the centralized collection of the impurities is formed.
