Solid-liquid separation device

Abstract

The invention relates to the technical field of biological fermentation treatment equipment, and particularly discloses a solid-liquid separation device, which comprises an obliquely arranged arc-shaped shell supported by a bracket, a filter screen cylinder is arranged in the shell, and the filter screen cylinder and the shell are provided with a plurality of roller supporting apparatuses in a supporting manner, the filter screen cylinder can rotate under the action of the plurality of roller supporting apparatuses; a plurality of paddles are arranged on the higher side of the interior of thefilter screen cylinder in the vertical direction, and a discharge port is formed in the lower side of the interior of the filter screen cylinder in the vertical direction; a discharged solid-liquid mixture impacts the blades, so that the filter screen cylinder rotates without an external power device, along with the rotation of the filter screen cylinder, the probability that meshes are blocked inthe filtering process can be reduced, the filtering efficiency is improved, sundries can be promoted to turn over in the screen cylinder through rotation, discharging of solid sundries is facilitated, and then the separation efficiency of the device is further improved.

Description

technical field [0001] The invention relates to the technical field of biological fermentation treatment equipment, in particular to a solid-liquid separation device. Background technique [0002] With the gradual increase of biogas projects, anaerobic fermentation of livestock and poultry manure will produce a large amount of biogas slurry. The problem of biogas slurry is becoming more and more prominent. Biogas slurry is a high pollutant and cannot be directly discharged into the environment. It is treated by building post-processing facilities to meet the standards. It also leads to a great increase in construction and operation costs, so there is a serious consumption problem. In fact, biogas slurry is rich in nitrogen, phosphorus, potassium, amino acids, rich in trace elements, B vitamins, various hydrolytic enzymes, organic acids and Bioactive substances such as humic acid are good organic fertilizers, which can stimulate crop growth, enhance crop resistance and improv...

Problems solved by technology

[0004] However, although the above-mentioned technology has an outstanding solid-liquid separation effect, the equipment that needs to be used has a complex structure and a small processing capacity, which is not conducive to the improvement of work efficiency.
