Problems solved by technology

[0002] The existing solid-liquid separator has only one layer of screen filter structure, and the separation capacity depends on the gap between the screen bars. Since the gap between the screen bars cannot be adjusted and the screen cannot be replaced, it cannot be adjusted according to the actual needs of the site.
If finer filtration is required, it is necessary to build another project and add a filter screen after the equipment, and the cost is high, and the dry humidity of the filter residue cannot be adjusted well, and the cleaning of the screen screen after filtration also requires labor.

Embodiment 1

[0032] like figure 1 and 2 As shown, a multi-stage solid-liquid separation device includes a casing 1 and a multi-stage screen filter mechanism 2 arranged in the casing 1 and a plurality of screw extrusion solid-liquid separation mechanisms 3; the casing 1 A waste water tank 12 provided with a feed inlet 11 and a bottom, the waste water tank 12 has a water outlet 13; the feed end of the first stage screen 21 of the multi-stage screen filter mechanism 2 is arranged on the casing 1 At the feed port 11 of the feed port, a screw extrusion solid-liquid separation mechanism 3 is provided at the discharge end of each level of screen 21; the solid material discharge ends of all screw extrusion solid-liquid separation mechanisms 3 are all arranged at the said Outside the casing 1.

[0033] The multi-stage solid-liquid separation equipment uses a multi-stage screen filter mechanism 2 and multiple screw extrusion solid-liquid separation mechanisms 3 to simultaneously filter the solid-l...

Embodiment 2

[0065] A multi-stage solid-liquid separation process, applied to the multi-stage solid-liquid separation equipment described in Example 1, the steps include:

[0066] Step 0: According to the final required dry humidity of the solid material, adjust the quantity of several elastic pressing pieces 35 on the solid material discharge end of each screw extrusion solid-liquid separation mechanism 3;

[0067] Step 1: putting the solid-liquid mixture requiring solid-liquid separation into the multi-stage solid-liquid separation equipment;

[0068] Step 2: the waste water filtered by the multi-stage screen filter mechanism 2 from the solid-liquid mixture flows into the waste water tank 12;

[0069] Wherein, said step 2 includes:

[0070] Step 2.1: The waste water in the solid-liquid mixture flows out from the gap between the screen bars 211 of the upper-level screen 21 to the water guide plate 22 below the screen 21 of this level;

[0071] Step 2.2: the waste water on the water guide ...

Abstract

The invention discloses multi-stage solid-liquid separating equipment. The multi-stage solid-liquid separating equipment comprises a housing, and a multi-stage screen filter mechanism and a plurality of screw extruding solid-liquid separating mechanisms which are arranged in the housing; the housing is provided with a feed inlet and a waste water tank at the bottom, and the waste water tank is provided with a water outlet; the feeding end of the first-stage screen of the multi-stage screen filter mechanism is arranged at the feed inlet of the housing, and the screw extruding solid-liquid separating mechanism is arranged at the discharge end of each stage of the screen; and the solid material discharge ends of all screw extruding solid-liquid separating mechanisms are arranged out of the housing. The multi-stage solid-liquid separating equipment disclosed by the invention filters a solid-liquid mixture in a combined manner by adopting the multi-stage screen filter mechanism and the plurality of screw extruding solid-liquid separating mechanisms, so that a better and more refined solid-liquid separating effect can be provided.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to a solid-liquid separation device. Background technique [0002] The existing solid-liquid separator has only one layer of screen filter structure, and the separation capacity depends on the gap between the screen bars. Since the gap between the screen bars cannot be adjusted and the screen cannot be replaced, it cannot be adjusted according to the actual needs of the site. If finer filtration is required, further construction and additional filter screens will be required after the equipment. The cost is high, and the dry humidity of the filter residue cannot be adjusted well, and the cleaning of the screen screen after filtration also requires labor. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a multi-stage solid-liquid separation device, which uses a multi-stage screen f...
