A kind of marsh gas raw materials charging machine
Technical field
The utility model belongs to biogas engineering device technical field, especially a kind of marsh gas raw materials charging 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 marsh gas raw materials charging machine, it has, and filling raw material is smooth, biogas not
It can be from the advantages that the leakage of raw material filler and simple in structure, easy-to-operate.
Technical solution is realized in used by the utility model:A kind of marsh gas raw materials charging machine, it includes setting up
Rack on tank for sewage gas top, it is characterised in that:Charge pipe is installed by flange on the nozzle on tank for sewage gas top, charge pipe
Lower end is stretched into nozzle and is extended to below tank for sewage gas internal liquid level, charge pipe top be higher by nozzle position side be equipped with plus
Hopper, the interior conveying axis being equipped with above and below charge pipe of charge pipe, charge pipe upper end is equipped with the bearing block and axis of installation conveying axis
It holds, the hypomere of conveying axis is equipped with flight and extends charge pipe lower end, the upper end installation big belt pulley of conveying axis, in charge pipe
Motor is fixedly mounted in the rack of side, small belt pulley is installed on the output shaft of motor, small belt pulley passes through skin with big belt pulley
V belt translation connects.
Further, the diameter proportion of small belt pulley and big belt pulley is 1:3-8.
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)The lower end of charge pipe and auger conveyor is all extended to below tank for sewage gas internal liquid level, in the process of charging
In, it ensure that the air-tightness of tank for sewage gas, marsh gas raw materials are delivered to by auger conveyor in liquid level, are conducive to raw material and are sufficiently mixed.
3)Conveying axis machine flight in charge pipe by motor by belt and belt wheel drive, small belt pulley and big belt
The diameter proportion of wheel is 1:3-8 does not need to setting retarder, and overall structure is simple, and dismounting is easy to maintenance, and processing and fabricating is easy,
It is of low cost.
