Examples:

referring to fig. 1-3, a water quality pretreatment device comprises a water delivery pipeline 1 and a filter residue mechanism arranged at the water outlet end of the water delivery pipeline 1, wherein a recovery pipeline 5 is arranged at the bottom of the filter residue mechanism. The working principle is that the water supply pipeline 1 guides a water source which needs pretreatment (removing larger solid matters in water) to the upstream surface of the filter residue mechanism, and then the water is guided away from the recovery pipeline 5 after the solid matters in the water are removed under the action of the filter residue mechanism.

The filter residue mechanism comprises a rotating shaft 2, a power source and a chain 4. Specific: the three rotating shafts 2 are arranged in parallel and distributed in a triangular direction, one rotating shaft 2 is connected with a power source, the power source is usually a motor, and the power source can drive the rotating shaft 2 to rotate continuously.

The chain comprises a plurality of chains 4 which are wound on three rotating shafts 2, the chains 4 form a triangle structure, and correspondingly, chain wheels matched with the chains 4 are arranged on the rotating shafts 2. All the chains 4 are arranged in parallel, and the intervals between the adjacent chains 4 are equal. Under the action of the power source, all chains 4 move on the rotating shaft 2.

One side of the triangle structure formed by the chain 4 is a water-facing surface which is inclined. The water flow output by the water outlet end of the water delivery pipeline 1 is converged with the water facing surface at a certain included angle. Solids on the chain 4 are removed on the other side of the triangular structure formed by the chain 4.

In this embodiment, firstly, a water source to be pretreated is guided to a filter residue mechanism through a water supply pipeline 1, and the water source is treated on the upstream surface of the filter residue mechanism.

In the filter residue mechanism, a rotating shaft 2 is driven to rotate through a power source, then a chain 4 moves on the rotating shaft 2, when water flow impacts on the upstream surface, the chain 4 intercepts large solid matters in water, the solid matters are transported to an area beyond the water flow under the driving of the chain 4, then the solid matters on the chain 4 are treated, so that the workload of workers can be reduced, and the working strength is lightened.

In one particular embodiment:

the residue filtering mechanism also comprises a residue lifting plate 3, a spike 7, a railing 8 and a side panel 6. Two L-shaped side panels 6 are arranged on two sides of all the rotating shafts 2, two ends of the rotating shafts 2 are rotationally connected with the side panels 6, two ends of the side panels 6 are respectively rotationally provided with one rotating shaft 2, and corners of the side panels 6 are rotationally provided with one rotating shaft 2.

A plurality of rails 8 are fixedly arranged between the two side panels 6, all the rails 8 are positioned on the upstream surface, the chain 4 spans all the rails 8 and is in sliding contact with the rails 8, and the distance between two adjacent rails 8 is equal.

Each chain 4 is provided with a plurality of spikes 7, the length square of each spike 7 is perpendicular to the chain 4, and the intervals between the adjacent spikes 7 are equal. The spike 7 moves with the chain 4.

In this embodiment, a plurality of balustrades 8 are provided, so that the balustrades 8 and the chains 4 together form a net structure, thereby preventing solids in water from passing through gaps between the chains 4 and enhancing the filtering effect.

The chain 4 is provided with the stabs 7, so that filtered solid objects can be prevented from sliding off the chain 4 under the action of water flow. Then, when the solid matters move to the slag plate 3 along with the chain 4, the solid matters are separated from the chain 4 through the rods at the end parts of the slag plate 3, and then the solid matters are guided away from the chain 4 under the action of the inclined slag plate 3.
