[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3 As shown, a waste slurry recycling system with three-stage filtration includes a raw material pool 1, which is used to temporarily store waste slurry. The waste slurry from concrete production is introduced into the raw material pool 1 for precipitation. The raw material pool 1 is supported on the ground by a bracket, and the floating part of the waste slurry after precipitation is discharged through a discharge pipe 2 provided on the raw material pool 1. A discharge pump 3 is connected to the discharge pipe 2, and a treatment box 4 is connected to the end of the discharge pipe 2. The waste slurry is pumped into the treatment box 4 by the discharge pump 3 as a power device, and the waste slurry is filtered and treated by the treatment box 4.

[0022] A feed port 5 is provided on the top of the processing box 4 for the feed pipe to pass through. A primary separation drum 6 is installed on one side of the feed port 5. A secondary separation drum 7 is coaxially arranged outside the primary separation drum 6. A tertiary separation drum 8 is coaxially arranged outside the secondary separation drum 7. The primary separation drum 6, the secondary separation drum 7 and the tertiary separation drum 8 form a three-level filtering structure, and the three drums move synchronously to filter the waste pulp step by step and refine the solid waste grade generated by the filtration.

[0023] Therefore, the mesh apertures of the first-stage separation drum 6, the second-stage separation drum 7 and the third-stage separation drum 8 are gradually reduced, and solid wastes of different particle sizes are intercepted through step-by-step filtering and interception, which is convenient for graded utilization.

[0024] The shaft end of the primary separation drum 6 passes through the feed port 5 for feeding, and the shaft ends of the primary separation drum 6, the secondary separation drum 7 and the tertiary separation drum 8 are integrally connected, and the shaft ends on the same side of the primary separation drum 6, the secondary separation drum 7 and the tertiary separation drum 8 are connected through a rotating plate 9, and the rotating plate 9 is rotated by synchronous driving. A driving motor 10 is arranged on the top of the processing box 4, and a gear set 11 is arranged on the driving motor 10 to be linked with the rotating plate 9. The gear set 11 is driven to rotate by the driving motor 10, so that the gear set 11 drives the rotating plate 9 to rotate, so that the primary separation drum 6, the secondary separation drum 7 and the tertiary separation drum 8 are synchronously rotated, thereby improving the utilization rate of the power equipment.

[0025] A flocculant adder is provided on the annulus between the secondary separation drum 7 and the primary separation drum 6. In order to treat the wastewater more thoroughly, flocculant is added to the annulus between the secondary separation drum 7 and the primary separation drum 6 through the flocculant adder, so that the primary filtered waste liquid separated by the primary separation drum 6 undergoes flocculation reaction, thereby intercepting harmful substances.

[0026] Furthermore, the spacing of the annular spaces between the primary separation drum 6 and the secondary separation drum 7 is the same as the spacing of the annular spaces between the secondary separation drum 7 and the tertiary separation drum 8 .

[0027] Furthermore, a plurality of sealing ring sleeves of a concentric ring structure are provided at the bottom of the processing box 4 to respectively seal the bottom ends of the primary separation drum 6, the secondary separation drum 7 and the tertiary separation drum 8 to prevent the separated waste liquid from flowing back and affecting the separation effect.

[0028] Furthermore, a drain pipe 12 is provided on one side of the processing box 4 and is connected to the annular space between the three-stage separation drum 8 and the processing box 4 , and the triple-filtered water is discharged through the drain pipe 12 .

[0029] Furthermore, the flocculant additive includes a flocculant addition pipe 13, which is connected to the top of the processing box 4. An annular cavity 14 is provided on the processing box 4 and is connected to the flocculant addition pipe 13. A plurality of diversion ports 15 are provided on the top of the annular space between the secondary separation drum 7 and the primary separation drum 6 and are connected to the annular cavity 14.

[0030] The flocculant is injected into the annular cavity 14 through the flocculant addition pipe 13 , so that the flow is diverted to the multiple diversion ports 15 through the flow of the annular cavity 14 , and then discharged from the diversion ports 15 into the annular space between the secondary separation drum 7 and the primary separation drum 6 .

[0031] The waste pulp recycling system with three-stage filtration performs multi-stage screening on the waste pulp through the coaxially arranged primary separation drum 6, secondary separation drum 7 and tertiary separation drum 8, so as to grade the solid waste in the waste pulp, and a flocculant adder is arranged between the secondary separation drum 7 and the primary separation drum 6 to further flocculate the waste liquid, thereby improving the separation effect in combination with the multi-stage separation method.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
