Large-sized biogas fermentation tank raw material charging machine
Technical field
The utility model belongs to biogas engineering device technical field, especially a kind of large-sized biogas fermentation tank raw material filling
Machine.
Background technology
Large-sized biogas fermentation tank is generally using complete hybrid fermentation tank, bulky, the agricultural crop straw process of fermentation tank
As raw material after being mixed after crushing with water or biogas slurry, fill to progress sealed fermenting in fermentation tank and generate biogas.
In the prior art, large-sized biogas fermentation system is all uninterrupted continuous work, in the fermentation production process of biogas
Middle filling raw material, this requires keeping the pressure inside fermentation tank during raw material is filled, biogas cannot be filled from raw material
Mouth leaks out, while also to overcome the problems, such as that biomass material swims in bad filling on the water surface.
Invention content
The purpose of this utility model is to provide a kind of large-sized biogas fermentation tank raw material charging machines, it is suitable with filling raw material
Freely, biogas will not from raw material filler leak and also simple in structure, operational safety, it is easy to operate the advantages that.
Technical solution is realized in used by the utility model:A kind of large-sized biogas fermentation tank raw material charging machine,
It includes rack, it is characterised in that:Tank for sewage gas top is stretched into the longitudinally fixed installation charge pipe in rack, the lower end of charge pipe
It in nozzle and extends to below tank for sewage gas internal liquid level, is connected between charge pipe and nozzle by flange seal, in charge pipe
Extend the auger conveyor of charge pipe lower end equipped with lower end, the side of charge pipe is equipped with loading hopper, and the upper end of charge pipe is installed
There are the retarder and motor of driving auger conveyor rotation.
The utility model has the advantage of:
1)The longitudinally fixed installation charge pipe in rack, the central shaft of the auger conveyor inside charge pipe is also longitudinal direction
Installation, this and inclination installation are compared, and auger conveyor operates steadily, and service life is long.2)Under charge pipe and auger conveyor
End is all extended to below tank for sewage gas internal liquid level, during charging, ensure that the air-tightness of tank for sewage gas, marsh gas raw materials by
Auger conveyor is delivered in liquid level, is conducive to raw material and is sufficiently mixed.3)Motor, retarder, charge pipe and auger conveyor are all
On same axis, overall structure advantages of simple, processing and fabricating is easy, of low cost.

Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of large-sized biogas fermentation tank raw material charging machine, it includes rack 1, longitudinally fixed in rack 1
Charge pipe 2 is installed, the lower end of charge pipe 2 is stretched into the nozzle 4 on tank for sewage gas top 3 and extended under tank for sewage gas internal liquid level
Face is tightly connected between charge pipe 2 and nozzle 4 by flange 5, extends the spiral shell of 2 lower end of charge pipe in charge pipe 2 equipped with lower end
Conveyer 6 is revolved, the side of charge pipe 2 is equipped with loading hopper 7, and the upper end of charge pipe 4 is equipped with subtracting for the driving rotation of auger conveyor 6
Fast device 8 and motor 9.
Finally it should be noted that more than specific embodiment be only to illustrate the technical solution of the utility model rather than
Limitation to scope of protection of the utility model, the letter that those of ordinary skill in the art carry out the technical solution of the utility model
Single modification or equivalent replacement, all without departing from the spirit and scope of technical solutions of the utility model.
