In order to realize the discharge of the solid material, the fermenter of the present invention is provided with a head 13 at the end of the can body 5 on the side of the discharge port 6, and the head 13 is connected to the can body 5 by bolts. The head 13 is detachable and openable, and at the end of the fermentation, the can body head 13 on the side of the discharge port 6 is disassembled and opened, and the entire can body 5 is discharged in a rotating state.
本发明中,由于发酵罐工作一段时间后,内部压力会变化,为安全起见,本发明在罐体5上安装有排气阀,当内部气压大于安全阈值时,如安全阈值为五个大气压,则打开排气阀,将内部气压降至五个大气压以下;类似地,当发酵罐需要重新装入物料时,应将发酵罐内部压力设为与外部压力相同,即一个大气压,此时打开安全阀,调节发酵罐内部压力至一个大气压。
In the present invention, since the internal pressure changes after the fermentation tank is operated for a period of time, the present invention is provided with an exhaust valve on the tank 5 for safety, and when the internal air pressure is greater than a safety threshold, such as a safety threshold of five atmospheres, Then open the exhaust valve to reduce the internal air pressure to below 5 atmospheres; similarly, when the fermenter needs to be reloaded, the internal pressure of the fermenter should be set to the same as the external pressure, that is, one atmosphere, then open safely. The valve adjusts the internal pressure of the fermenter to an atmospheric pressure.
发酵过程中会产生氨气、硫化物等废气,为了减少环境污染,将排气阀和安全阀与气体回收喷淋系统连接,罐内易溶于水且占比较大的氨气等气体通过喷淋吸收,硫化物可选择其它方式吸附,使得对环境的影响处于可控状态。In the fermentation process, ammonia gas, sulfide and other exhaust gases are generated. In order to reduce environmental pollution, the exhaust valve and the safety valve are connected with the gas recovery spray system, and the gas in the tank is easily dissolved in water and accounts for a relatively large amount of ammonia gas. Leaching absorption, sulfides can be adsorbed in other ways, so that the impact on the environment is in a controlled state.
需要说明的是,本发明罐体5的端壁指的是图1中横放的罐体5左右两端的端壁,内侧壁指的是筒形罐体5的径向上的侧壁。It should be noted that the end wall of the can body 5 of the present invention refers to the end walls of the left and right ends of the can body 5 which are horizontally placed in Fig. 1, and the inner side wall refers to the side wall in the radial direction of the cylindrical can body 5.
需要说明的是,本发明发酵罐的物料包括人类动物排泄物或者其他有机物,本发明的创造性体现在全封闭及对物料的搅拌上,使物料与氧气充分接触,提高发酵效果和发酵效率。由于上述物料的含水量可高达65%,有较强的粘性,这就造成了发酵过程中有效的、无死角的提供发酵菌种所需的氧气成了生产过程中的重点。传统的搅拌方式未做到全封闭,会造成对环境的二次污染。若罐体5内使用外力驱动中心轴9旋转,通过搅拌叶的工作以达到搅拌和补充氧气的效果,因物料含水量高的原因会势必造成物料发酵的死角,难以保证物料高质量整体的一个发酵进程。同时外力驱动中心轴9的方式破坏了罐体5的完整性,在带压工作中气密性也会凸显。本发明正是通过罐体5的旋转带动搅拌叶的转动,提高物料与氧气的接触面积,罐体5内无死角,能加快物料的降解,物料的发酵效果好,提高了发酵效率。本发明的发酵罐能够实现了封闭发酵的过程,为人类的粪便处理提供了可操作、可实现的方案。目前,还没有对人类的粪便进行处理的发酵罐,本发明弥补了这一不足。It should be noted that the material of the fermenter of the present invention includes human animal waste or other organic matter, and the inventive concept is embodied in the full sealing and the stirring of the material, so that the material is in full contact with oxygen, thereby improving the fermentation effect and the fermentation efficiency. Since the water content of the above materials can be as high as 65% and has a strong viscosity, the oxygen required for providing the fermenting bacteria in the fermentation process, which is effective and has no dead angle, becomes the focus of the production process. The traditional mixing method is not completely closed, which will cause secondary pollution to the environment. If the external force is used to drive the central shaft 9 to rotate in the tank body 5, the work of stirring the leaves to achieve the effect of stirring and replenishing oxygen, due to the high moisture content of the material, it will inevitably lead to a dead angle of material fermentation, and it is difficult to ensure a high quality overall material. Fermentation process. At the same time, the manner in which the external force drives the center shaft 9 destroys the integrity of the can body 5, and the airtightness is also highlighted during the belt pressing operation. The invention drives the rotation of the stirring blade by the rotation of the can body 5, improves the contact area between the material and the oxygen, has no dead angle in the tank body 5, can accelerate the degradation of the material, has good fermentation effect of the material, and improves the fermentation efficiency. The fermentor of the present invention enables a closed fermentation process and provides an operational and achievable solution for human fecal management. At present, there is no fermenter for treating human feces, and the present invention makes up for this deficiency.
