A multi-stage elliptical solid-liquid separator

Abstract

The invention provides a multi-stage oval superposed solid-liquid separator comprises two stages of carrying surfaces which are connected end to end, wherein each stage of carrying surfaces can be used for carrying an treated object with a certain solid-liquid ratio to the tail end from the beginning end and dehydrating the treated object in the process; the treated object is longitudinally conveyed from the front-stage carrying surface to the rear-stage carrying surface, and the terrain at the tail end of the front-stage carrying surface is higher than that at the beginning end of the rear-stage carrying surface to form terrain difference; a guide structure is arranged between the adjacent two stages of carrying surfaces for guiding the treated object from the tail end of the front-stage carrying surface to the beginning end of the rear-stage carrying surface. After being conveyed to the tail end through the front-stage carrying surface, the treated object is turned over and dropped to the beginning end of the rear-stage carrying surface by virtue of the guide structure, and the water in the treated object is turned over and guided out, so that the water of the treated object is discharged in a facilitated manner, the solid-liquid ratio of the treated object is increased, water produced by squeezing is reduced, water draining requirements of a liquid outlet structure are lowered, and the dehydrating effects of the squeezed treated object are improved.

Description

technical field [0001] The invention relates to a multi-stage elliptical solid-liquid separator, which belongs to the technical field of environmental protection equipment. Background technique [0002] In fields such as environmental protection and animal husbandry, it is often necessary to separate solid substances from liquid-solid mixtures in order to treat solid substances and liquids separately. [0003] Chinese patent document CN203697509U discloses a solid-liquid separation device, which includes a body and a lower frame supporting the body, and also includes a plurality of rotary shafts arranged in parallel, and a plurality of rotary bodies arranged in parallel in the axial direction of each rotary shaft, the adjacent rotary The structure in which the liquid in the processed object formed in the middle of the rotating body is squeezed to make the liquid fall between the gaps, the pressing part arranged above the rotating body, and the outlet part arranged on the upp...

Problems solved by technology

[0005] Therefore, the technical problem to be solved in the present invention is to overcome the problem that the solid-liquid separation device in the prior art cannot discharge the water intercepted by the treatment object itself due to the carrying surface, and the solid-liquid ratio is low when the treatment object reaches the pressing part, which will cause a problem after being squeezed. A large amount of water is difficult to discharge, resulting in low dehydration rate and poor dehydration effect of the processed product, so as to provide a method that can guide the intercepted water during the process of conveying the processed product, and improve the solid-liquid ratio when the processed product reaches the pressing part. A multi-stage elliptical solid-liquid separator that reduces the moisture produced by extrusion and improves the dehydration rate and dehydration effect of the treated product
