Problems solved by technology

[0003] In order to overcome the disadvantages of existing biogas slurry separation equipment that biogas residues and crude straw fibers are easy to block the screen of the separation device, and it is necessary to periodically stop the solid-liquid separation of the biogas slurry to clean the screen, the invention provides a biogas slurry filter machine, the biogas slurry filter can not only achieve solid-liquid separation of biogas slurry, but also can clean the screen at any time to achieve continuous work for a long time

Abstract

The invention discloses a biogas slurry filter which belongs to a liquid filtering machinery article, especially a biogas slurry filter used for separation of biogas slurry generated by a biogas digester. The biogas slurry filter comprises a pedestal, a housing disposed on the pedestal, and a power device; the housing is provided with a biogas slurry input pipe at the front and a biogas residue outlet pipe at the lower portion of the rear end; the pedestal is provided with a biogas slurry discharging pipe; a hollow rotating cylinder is disposed about a rotating shaft in the center of a filter screen, and at least two long-strip scraping plates, each of which is at a slope of 8-12 DEG to the axis of the rotating cylinder, are respectively inlayed at the periphery of the cylinder, a bush plate with manes is inlayed on the top surface of the rotating cylinder, and the top surface of each long-strip scraping plate and the manes of the brush plate both abut the filter screen. The disadvantages in the prior art is solved that a biogas slurry separating machine has to stop working because of removal of the biogas residue and straw crude fibers which are adhered to a cylinder-shaped filter screen, and the biogas slurry filter can continuously filtrate the biogas slurry generated by the biogas digester into a biogas slurry suitable for crop foliar fertilization, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to a mechanical product for liquid filtration, in particular to a biogas slurry filter for separating biogas slurry produced by a biogas tank. Background technique [0002] Use clean biogas slurry and clear water to spray fertilizer on the crop leaves with a sprayer in a certain proportion, and the effect of increasing production is very obvious. To use clean biogas slurry, it is necessary to filter out the biogas residue and straw crude fiber present in the biogas slurry, otherwise the biogas residue and straw coarse fiber will block the nozzle of the sprayer and affect the use of the biogas slurry as crop foliar fertilizer. At present, the separation of biogas slurry mostly adopts screening method or extrusion method, but the common disadvantages are complex structure, high equipment cost, inconvenient maintenance, and troublesome replacement of mesh screen. CN 202446903 U discloses a biogas slurry solid-liquid separation devic...
