Description
Technical Field
The utility model relates to a methane-generating pit technical field especially relates to a biogas fermentation tank top dross crust breaking device.
Background
At present, the rural biogas in China develops rapidly, and most biogas projects adopt an overground biogas fermentation tank. When biogas fermentation is carried out, straws are used as main raw materials for anaerobic fermentation, a fermentation tank is in a static state after charging, the straws and the like float upwards due to large volume and small specific gravity and are difficult to decompose for a long time, and float in a gas storage chamber of the fermentation tank, are slowly lack of water, are dried, condensed and crusted, influence the fermentation effect of the biogas, and even cause the accident of breaking the top of the fermentation tank due to too thick scum. At present, the crust breaking method comprises a rest crust breaking method, an inflation crust breaking method and a mechanical stirring method, wherein the rest crust breaking method can not continuously supply air, the inflation crust breaking method is complex to operate, the mechanical crust breaking method consumes external power, and the crust breaking effect is poor only by stirring.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect of poor shell breaking effect of simple stirring in the prior art and providing a device for breaking the scum at the top of a biogas fermentation tank.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a biogas fermentation cylinder top dross crust breaking device, includes lid and carousel, the downside of lid is fixed with the apical ring, and the downside height of apical ring is uneven, the carousel is located the downside of lid, and the coaxial connecting axle that is fixed with of upside of carousel, the connecting axle passes through sealed bearing and is connected with the lid, the upper end of connecting axle is fixed with driven gear, and the meshing is connected with the driving gear on the driven gear, the driving gear passes through connecting axle coaxial coupling and has the windmill, sliding connection has the vertical crust breaking rod that corresponds with the apical ring on the carousel, the top of crust breaking rod is passed through the spring and is connected with the carousel.
Preferably, the lower side of the top ring is wavy.
Preferably, a windmill frame is installed on the upper side of the cover body, and a connecting shaft of the windmill is rotatably connected in the windmill frame.
Preferably, the upper end of the shell breaking rod is provided with a limiting ring.
Preferably, the upper end of the spring is connected with the lower side of the limit ring.
The utility model has the advantages that:
1. the utility model discloses not only can stir biogas fermentation tank inside, the prevention crust breaking, the pole of breaking the crust can also reciprocate at the in-process of stirring, and the crust that will have generated is broken.
2. The utility model discloses installed the windmill at the top, accessible wind-force drive carousel rotates, need not the electric power energy supply.
