US 9,540,605 B2 · Biogas plant

Abstract

A biogas plant contains a fermenter vessel, in which an assembly support is mounted, preferably vertically oriented. An assembly, in particular a submersible motor driven stirrer, is retained by a height adjustment device so as to be vertically adjustable on the assembly support. Accordingly, the height adjustment device is formed by a belt drive of which a traction device is guided around at least two deflecting elements spaced apart from one another in the longitudinal direction of the assembly support. At least one of the deflecting elements can be driven in rotation by a driving device and the assembly is coupled to the traction device in such a way that when the deflecting element is rotationally actuated in a first direction the assembly is raised and when the deflecting element is rotationally actuated in a second, opposite direction, the assembly is lowered.

Dependent claims

A biogas plant, comprising:

a fermenter tank having a tank inner space;
an upper chain wheel;
a lower chain wheel spaced apart from said upper chain wheel;
an articulated traction chain mounted vertically within said tank inner space and engaging with said upper and lower chain wheels, said articulated traction chain having axes of articulation which are oriented axially parallel to an axis of rotation of said upper and lower chain wheels;
a carrier coupled to said articulated traction chain;
a submersible motor-driven agitator mounted on said carrier;
an outlet orifice for drawn-up solids positioned above said upper chain wheel, said outlet orifice having two lead jaws spaced apart and set obliquely, said two lead jaws ensuring a functionally reliable engagement between said articulated traction chain and said upper chain wheel;
and
an arcuate lead plate positioned below said lower chained wheel.
