The use method and the advantages of the invention are as follows: when the efficient floc separating device for treating chemical sewage is used, the working process is as follows:

as shown in fig. 1, the starting motor and the belt conveyor 7 work, the waste water of the styrene butadiene rubber added with the chemicals and reacted through the liquid inlet pipe 5 is conveyed to the inside of the filter cylinder 10 through the liquid inlet pipe 5, the flocculate is left on the inner side wall of the filter cylinder 10 through the filtration of the filter cylinder 10, and the clear water is discharged through the filtering hole of the filter cylinder 10 and falls into the water receiving hopper 4, and then is discharged through the drain pipe 28, thereby realizing the separation of the flocculate, improving the separation efficiency, reducing the working procedure duration, and improving the working efficiency of sewage treatment.

Drive a pivot 19 after the motor work and rotate, make a 19 synchronous driving fluted disc 17 of pivot rotate, fluted disc 17's rotation drives ring gear 13 through the tooth transmission effect between the remaining ring gear 13 of fluted disc 17 and rotates, thereby make ring gear 13 drive cartridge filter 10 in step rotate, cartridge filter 10's rotation makes cartridge filter 10's inside wall circulation be in the exit end downside of feed liquor pipe 5, and then avoid the flocculate to be in the same position of cartridge filter 10's inside wall, lead to the flocculate to pile up the inside wall that blocks up cartridge filter 10 after, thereby ensure to remain cartridge filter 10's filter effect all the time, and then improve cartridge filter 10 efficient filtration efficiency.

The first rotating shaft 19 rotates and simultaneously drives the second connecting rod 18 to rotate, so that the second connecting rod 18 applies a pulling force or a pushing force to the shaft rod 32 through the first connecting rod 16, as shown in fig. 1, fig. 2 and fig. 3, so that the shaft rod 32 synchronously drives the two lantern rings 31 to slide on the corresponding twist rod 6 in a reciprocating manner along the length direction of the twist rod 6, and further, the lantern rings 31 synchronously drive the vertical frame 12 to slide in a reciprocating manner along the length direction of the twist rod 6, the vertical frame 12 synchronously drives the brush roll 11 to clean flocs on the inner side wall of the filter cylinder 10 through the second rotating shaft 35 while sliding, so that the inner side wall of the filter cylinder 10 is kept from being blocked by the flocs, and high-efficiency filtering efficiency is always kept, the flocs cleaned by the brush roll 11 fall on the belt conveyor 7 and are conveyed to the outer side of the filter cylinder 10 by the belt conveyor 7, so as to realize the collection and output of the flocs, need not the manual operation, reduce intensity of labour, improve work efficiency, and can go on simultaneously with the separation of flocculation thing, simplify the process, it is long to reduce the process, the rotation of cartridge filter 10 makes the inner wall region after the brush roll 11 is clean remove to the exit end department of feed liquor pipe 5, so that make cartridge filter 10 efficient filtering area filter the flocculation thing in the waste water, keep efficient filtration efficiency and effect, and simultaneously with feed liquor pipe 5 exit end department filter the position that has the flocculation thing and rotate to brush roll 11 department, so that clean and collect the flocculation thing on the cartridge filter 10 inside wall, it is long to reduce intensity of labour and process.

As mentioned above, the synchronous drive disc 33 is made reciprocating sliding along the length direction of the twist rod 6 in the sliding process of the lantern ring 31, and under the torsion action of the helicoid of the twist rod 6, the disc 33 is made to slide along the length direction of the twist rod 6 and rotate, so that the disc 33 drives the two rotating shafts 35 to rotate through the belt wheel assembly 34, and further the two rotating shafts 35 drive the brush roller 11 to rotate, thereby improving the cleaning effect and efficiency of the brush roller 11 on the inner side wall of the filter cartridge 10, ensuring that the filter cartridge 10 is not blocked by flocculates, always keeping high-efficiency filtering efficiency, and improving the collecting efficiency of the flocculates.

As shown in fig. 1, in the process that the first connecting rod 16 applies a pulling force or a pushing force to the shaft rod 32, the sliding sleeve 15 is synchronously driven to make reciprocating up-and-down movement in the vertical direction, so that the sliding sleeve 15 applies a pulling force or a pressure to the pressure rod 21, so that the pressure rod 21 synchronously drives the piston plate 22 to move up or down, when the piston plate 22 moves down, the piston plate 22 applies a downward pressure to the water in the cylinder 25, so that the water pressure is increased, since the conduction direction of the first check valve 24 points to the diversion pipe 30, and the conduction direction of the second check valve 27 points to the cylinder 25, the high-pressure water in the cylinder 25 is conveyed to the diversion pipe 30 through the first water pipe 23, and is shunted to each water nozzle 29 by the diversion pipe 30, and then is sprayed to the outer side wall of the filter cylinder 10 by each water nozzle 29, so that the water reversely washes the filter holes from the outer side wall of the filter cylinder 10, and prevents flocs from being blocked in the filter holes from being completely cleaned by the brush roll 11, the cleaning effect and efficiency of the filter cartridge 10 are improved, the filter cartridge 10 is ensured not to be blocked by flocculated matters, the efficient filtering efficiency is always kept, when the piston plate 22 moves upwards, the piston plate 22 enables the volume in the cylinder barrel 25 to be increased, and suction force is generated, because the conduction direction of the first check valve 24 is directed to the diversion pipe 30, and the conduction direction of the second check valve 27 is directed to the cylinder barrel 25, the suction force pumps water liquid which is separated from the flocculated matters in the water discharge pipe 28 into the cylinder barrel 25 through the second water pipe 26, automatic water replenishing is realized, the water liquid is conveyed into the diversion pipe 30 again, and the water is sprayed to the outer side wall of the filter cartridge 10 by the water spray nozzles 29 to reversely flush the filtering holes, so that the efficient filtering efficiency of the filter cartridge is kept.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
