Abstract

The invention discloses an automatic crust breaking device for the top floating slags of a marsh gas fermentation tank. The automatic crust breaking device comprises a marsh gas tank body, a crust breaking mechanism and a stirring mechanism, wherein the marsh gas tank body is of a cylindrical structure; the upper part of the marsh gas tank body is fixedly provided with a load-bearing strip; the upper end of the marsh gas tank body is provided with an upper cover; the load-bearing strip is provided with a driving motor; a stirring shaft is connected below the driving motor; and the crust breaking mechanism is arranged below the load-bearing strip. By use of the automatic crust breaking device disclosed by the invention, the problems in the prior art that since the floating slags in the marsh gas fermentation tank are too thick, fermentation efficiency is low, a crust is unlikely to be cleaned since the crust is too hard and the like can be solved.

Description

technical field [0001] The invention belongs to the field of biogas tank fermentation, in particular to an automatic shell breaking device for scum on the top of a biogas fermentation tank. Background technique [0002] At present, there are more and more large-scale and medium-sized biogas projects using straw, cow dung, sheep manure, pig manure, etc. as raw materials. Most biogas projects use above-ground biogas fermentation tanks. The phenomenon of slag crusting affects the effect of biogas fermentation, and even the accident of breaking the top of the fermentation tank due to too thick scum. [0003] However, the existing biogas digesters with shell breaking function still have the following deficiencies: 1. The structure is relatively complicated, which is not suitable for popularization and application; The utilization efficiency of raw materials is low, and there is a problem that crusty raw materials are difficult to discharge during biogas fermentation.
