Abstract
The utility model relates to a screening device before cleaning oil-containing filter material, which is mainly used for solving the problems of blockage of screen meshes caused by easy adhesion of sticky substances on the surface of a screen line and low screening efficiency when the existing screening device is used for screening the filter material. The screening device is characterized by further comprising a water tank (7) and a spiral conveying device (6), the water tank (7) is arranged at the bottom of a drum screen (2), the bottom of the drum screen (2) is further immersed in water of the water tank (7), the bottom of the water tank (7) is tilted, and the lower end of the spiral conveying device (6) is arranged at the lowest place of the bottom part of the water tank (7). The screening device before cleaning the oil-containing filter material can solve the problem of blockage of the screen meshes due to the adhesion of the sticky substances on the surface of the screen line, and has the characteristics of good preliminary cleaning effect and high screening efficiency.
Description
Technical field:
The utility model relates to a kind of sewage disposal setting used on the oil field, separating screen device before a kind of specifically oil-containing filtrate cleans.
Background technology:
On the oil field, sewage clean through filtering tank last as by the particle size sorting, so that select better effects if, more economical cleaning equipment when cleaning for use.Used separating screen device is generally mechanical type at present, and modal is vibratory sieve, and the conventional vibration sieve is widely used in the sorting of non-stick substance solid particle, as ore particles sorting, flour sub-sieve, chemical products sub-sieve etc.And the discarded filter material surface of oilfield sewage filtering tank oil-containing is adsorbing crude oil, polymer and variation material thereof etc. in a large number, usually exist with the solid form that sticks into bulk under the normal temperature situation, when adopting the conventional vibration screening to select, the crude oil of filter material surface, polymer and variation material thereof etc. stick to sieve line surface, cause that mesh size diminishes, mesh stops up, situations such as the bulk granule can't sift out, sub-sieve inefficiency.
The utility model content:
When overcoming existing separating screen device sub-sieve filtrate, stickum easily sticks to the deficiency that sieve line surface causes mesh obstruction, sub-sieve inefficiency, separating screen device before the utility model provides a kind of oil-containing filtrate to clean, separating screen device had solved stickum and is adsorbed in sieve line surface and causes the mesh blocking problem before this oil-containing filtrate cleaned, have previous cleaning effective, divide screen capacity high characteristics.
The technical solution of the utility model is: separating screen device before a kind of oil-containing filtrate cleans, comprise rotary screen, also comprise tank, helix transporting device, tank is arranged at described rotary screen bottom, and the rotary screen bottom is immersed in the water of tank, and the lower end of described helix transporting device places bottom of gullet.
Described bottom of gullet tilts, and the lower end of described helix transporting device places the bottom of gullet lowest part.
The filtrate of mixing inlet, the outlet of coarse granule filtrate are arranged on the described rotary screen, and the filtrate outlet is arranged at the bottom of described helix transporting device upper end.
The utlity model has following beneficial effect: owing to take such scheme, the rotary screen bottom is immersed in the water of tank, dispersant and cleaning agent are arranged in the water, can make the bulk filtrate be dispersed into individual particles, be easy to sub-sieve, coarse granule is discharged by the outlet of coarse granule filtrate, fine grained enters tank by the sieve aperture of rotary screen, be deposited to bottom of gullet, the lower end of helix transporting device places the tank lowest part, the fine grained of bottom of gullet can be extracted out; Simultaneously, owing in the water dispersant, cleaning agent are arranged, the cylinder mesh does not adsorb stickum, and stickum swims on the water surface, can reclaim separately.In sum, this separating screen device is difficult for stopping up mesh, divides the screen capacity height, has the previous cleaning effect, has alleviated the burden when operation is cleaned.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1-mixing filtrate inlet among the figure, 2-rotary screen, the outlet of 3-coarse granule filtrate, 4-motor, the outlet of 5-fine grained filtrate, 6-helix transporting device, 7-tank.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, separating screen device before a kind of oil-containing filtrate cleans, comprise rotary screen 2, the two ends of described rotary screen 2 are respectively mixes filtrate inlet 1, coarse granule filtrate outlet 3, also comprise tank 7, helix transporting device 6, tank 7 is arranged at described rotary screen 2 bottoms, in the tank 7 water is arranged, rotary screen 2 bottoms are immersed in the water of tank 7, be added with dispersant, cleaning agent in the water, be dispersed into individual particles fully under the impact force action that when the effect of dispersant, cleaning agent and rotary screen 2 roll, produces when the bulk filtrate immerses in the water, be easy to sub-sieve; Owing in the water dispersant, cleaning agent are arranged, do not adsorb stickum around rotary screen 2 meshes simultaneously, main stickum crude oil, polymer and variation material thereof etc. swim on the water surface, can adopt isolated plant in time to reclaim.Described tank 7 bottoms are preferably made skewed, fine grained filtrate in the tank 7 is assembled to lower, described helix transporting device 6 is in tilted layout, drive rotation by motor 4, filtrate outlet 5 is arranged at the bottom of its upper end, and the lower end places tank 7 bottom lowest parts, and the fine grained filtrate that assemble tank 7 bottoms finally flows to helix transporting device 6, be sent to the fine grained filtrate by helix transporting device 6 and export 5 places, reclaim.
During this separating screen device work, rotary screen 2, helix transporting device 6 rotate simultaneously, by decomposing under the effect that mixes dispersant in water of filtrate that filtrate inlet 1 enters rotary screen 2, cleaning agent, the coarse granule filtrate is discharged by the coarse granule filtrate outlet 3 of rotary screen 2 other ends, the fine grained filtrate enters in the tank 7 through the mesh of rotary screen 2, under the effect of gravity, assemble, upwards carry, discharge by fine grained filtrate outlet 5 by helix transporting device 6 to helix transporting device 6 places.This separating screen device has solved stickum and has been adsorbed in the problem that sieve line surface causes mesh size to diminish; Dispersant in the water and cleaning agent have solved filtering material particle bulk sticking problem, have the previous cleaning effect simultaneously, the burden when alleviating the subsequent processing cleaning; The filtrate that blocks in the mesh comes off under the gravity effect when arriving the top along with the rotation of cylinder automatically, solved the problem that filtrate stops up mesh; The sub-sieve process realizes mechanization, raises the efficiency, reduces labour intensity.
