The utility model relates to a dredging device of a biogas fermentation tank.

Background

In the process of biogas fermentation, after the fermentation tank works for a period of time, sludge is deposited at the bottom of the fermentation tank, the sludge is mainly formed by depositing inorganic substances such as soil, sand and the like brought in when fermentation raw materials enter the fermentation tank and waste materials generated after reaction of partial fermentation raw materials, the sludge has no effect on the fermentation process, a large amount of sludge occupies the effective volume of the fermentation tank, the fermentation efficiency of the fermentation tank is reduced, and the fermentation tank must be cleaned in time. In actual work, the sludge is discharged out of the fermentation tank through a sewage discharge port in a biogas slurry flushing mode. However, in the actual operation process, the washing effect is not good, and the reason is that through analysis: 1, in a place far away from a sewage discharge outlet, the force for washing the biogas slurry is too small to take away the sludge, so that the more sludge is deposited; 2, after the fermentation tank works for a long time, the deposited sludge can be tightly combined layer by layer to form hardened solid which is tightly adhered to the bottom and the wall of the tank, so that the sludge is difficult to be taken out of the fermentation tank by the washing of biogas slurry.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in figure 1, figure 2, figure 3 and figure 4, a biogas fermentation tank dredging device comprises a fermentation tank body 1 and a dredging mechanism arranged in the fermentation tank body 1, wherein a sewage discharge outlet 2 is arranged at the bottom of the fermentation tank body 1, the dredging mechanism comprises a driving mechanism, a transmission mechanism and a vibration mechanism, the vibration mechanism is uniformly distributed at the bottom of the fermentation tank body 1, the driving mechanism is arranged at the upper part of the fermentation tank body 1, and the driving mechanism is connected with the vibration mechanism through the driving of the transmission mechanism.

In practice, the driving mechanism is arranged at the upper part in the fermentation tank body 1 and above the fermentation liquid, so that the influence of the fermentation liquid on the driving mechanism is avoided. The vibrating mechanism is uniformly distributed at the bottom of the fermentation tank body 1, the driving mechanism drives the vibrating mechanism to vibrate through the transmission mechanism, the vibrating action of the vibrating mechanism plays a role in stirring the sludge, and the sludge is effectively prevented from being deposited and hardened.

Specifically, drive mechanism includes motor 3 and support 4, motor 3 passes through support 4 sets up on fermentation cylinder body 1. The transmission mechanism comprises a transmission belt 5 and a transmission shaft 6, the transmission shaft 6 is horizontally arranged at the bottom of the fermentation tank body 1, one end of the transmission shaft 6 is arranged on an eccentric wheel 8, and the other end of the transmission shaft 6 is connected with the driving mechanism through the transmission belt 5.
