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

[0047] 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.

[0048] The multi-stage solid-liquid separation device uses a multi-stage screen filter mechanism 2 and multiple screw extrusion solid-liquid separation mechanisms 3 to simultaneously filter the suspension...

Embodiment 2

[0080] A multi-stage separation process for suspension, applied to the multi-stage solid-liquid separation device described in Example 1, the steps include:

[0081] 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;

[0082] Step 1: putting the suspension requiring solid-liquid separation into the multi-stage solid-liquid separation device;

[0083] Step 2: the wastewater filtered by the multi-stage screen filter mechanism 2 flows into the wastewater tank 12;

[0084] Wherein, said step 2 includes:

[0085] Step 2.1: The wastewater in the suspension 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;

[0086] Step 2.2: the waste water on the water guide plate 22 is diverted to the feeding end of the next-lev...

Abstract

The invention discloses a multistage separation process for suspension applied to a multistage solid-liquid separation device. The multistage separation process comprises the steps of feeding, multistage screen separation, screw extrusion and separation, and the like. According to the multistage separation process for suspension, suspension is subjected to combined filtering by a multi-stage screen filtering mechanism and a plurality of screw extrusion and solid-liquid separation mechanisms, and an excellent and fine solid-liquid separation effect can be provided.

Description

technical field [0001] The invention relates to the technical field of suspension liquid separation, in particular to a multistage separation process. 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 separation process of the suspension, which uses a multi-stag...
