Preferably, the outside of described sludge sump and strainer tub is provided with and makes sludge sump and the into a single integrated structure support of strainer tub, described support is provided with fixed bearing, described upper strata screen cloth and lower screen are removably connected on corresponding fixed bearing respectively by a screen frame, and described cloth water tank is installed in the top of described support.
Preferably, the angle of inclination of described upper strata screen cloth is become the angle of 30 ° with horizontal plane.
Preferably, the woven polyethylene net of described upper strata screen cloth to be aperture be 1mm, lower screen is aperture is 40 object stainless steel cloths.
Preferably, mud discharging hole is provided with bottom described sludge sump.
Preferably, filter residue floss hole is provided with bottom described strainer tub.
Preferably, filter residue enclosing is provided with outside described strainer tub.
Compared with prior art, the utility model has the advantage of:
The utility model is sieved by two-stage and upper strata screen cloth is obliquely installed, and the impurity leached can be made automatically to tumble in strainer tub under its Action of Gravity Field, effectively removes silt, twister, particle in mud; And two-stage mesh size is descending, the frequent situation generation occurring blocking sieve aperture effectively can be prevented; Be provided with the cleaning assembly of screen cloth, both can on-line cleaning, also when plug-hole situation is serious, screen cloth can be disassembled and clean in detail or change; Sludge quality after being filtered by the utility model is higher, is of value to and is added recovery or the adjustment of mud biochemical system, and product water efficiency is higher.

Detailed description of the invention
For the ease of understanding the utility model, hereafter will do to describe more comprehensively, meticulously to the utility model in conjunction with Figure of description and preferred embodiment, but protection domain of the present utility model is not limited to following specific embodiment.
As shown in Figure 1, the dregs filter of a kind of mud of the present utility model, comprise sludge sump 10, screen cloth group and screen cloth cleaning assembly, screen cloth is mounted on the top of sludge sump 10, comprise upper strata screen cloth 4 and lower screen 9, upper strata screen cloth 4 is tilted to lower setting, and lower screen 9 is horizontally disposed with, and the aperture of upper strata screen cloth 4 is greater than the aperture of lower screen 9, screen cloth cleaning assembly is positioned at the top of screen cloth group.The utility model is sieved by two-stage, and upper strata screen cloth is tilted to lower setting, effectively can remove silt, twister, particle in mud; Two-stage mesh size is descending, effectively can prevent the frequent situation occurring blocking sieve aperture; And be provided with screen cloth cleaning assembly, and both can on-line cleaning screen cloth, also when plug-hole situation is serious, screen cloth can be disassembled and clean in detail or change.
In the present embodiment, also comprise strainer tub 16, strainer tub 16 and sludge sump 10 are arranged side by side, and be provided with mud discharging hole 11, be provided with filter residue floss hole 7 bottom strainer tub 16 bottom sludge sump 10.The outside of sludge sump 10 and strainer tub 16 is provided with support 14, support 14 makes sludge sump 10 and strainer tub 16 form integrative-structure, support 14 is provided with fixed bearing 5, upper strata screen cloth 4 is removably connected on corresponding fixed bearing 5 by upper strata screen frame 3, and make the low side of upper strata screen cloth 4 and the inner space of strainer tub 16, the filter residue on upper strata screen cloth 4 can be made automatically to tumble in strainer tub 16 under gravity state.Lower screen 9 is removably connected on corresponding fixed bearing 5 by lower screen support 12, and upper and lower layer screen cloth is removably connected on fixed bearing, facilitates its cleaning and changes.
In the present embodiment, screen cloth cleaning assembly comprises a cloth water tank 1, and cloth water tank 1 is installed in the top of support 14, arranges higher than screen cloth group.The bottom of cloth water tank 1 is communicated with high-pressure water pipe 15, the water side of high-pressure water pipe 15 is provided with two high pressure nozzles, be respectively hydraulic spray 2 and lower hydraulic spray 13, upper hydraulic spray 2 is located at the top of upper strata screen cloth 4, and lower hydraulic spray 13 is located at the top of lower screen 9.High water pressure is 70MPa, and flow velocity is 70L/min.After emptying sludge sump, can to clean screen cloth inject high pressure water after sludge filtration.The impurity be wrapped on upper strata screen cloth 4 can rinse and enter strainer tub 16 under the water under high pressure effect of hydraulic spray ejection, and filter residue is discharged by filter residue floss hole 7.And the impurity on lower screen 9 can rinse and enters sludge sump 10 under water under high pressure effect, filter residue can be discharged by mud discharging hole 11 equally.
