technical field

The utility model relates to the field of waste recycling processing, in particular to an anaerobic fermentation device.

Background technique

With the gradual improvement of people's living standards, animal husbandry has gradually become stronger, and a large amount of manure is produced in the process of raising livestock and poultry. In the past, people directly threw the manure into the garbage dump or sprinkled it in the fields. Later, due to the appearance of biogas, people scientifically The improvement of technology will rationally process and recycle the manure of livestock and poultry. The manure from the farm will be washed into the water collection well, and then the liquid after solid-liquid separation and acidification adjustment will enter the anaerobic fermentation tank. At the same time, the straw will be crushed into the In the anaerobic fermentation tank, the mixed anaerobic fermentation is used to process and finally form biogas; however, the structure of the traditional anaerobic fermentation device is too simple, only the tank body is fermented, but during the fermentation process, the oxygen conditions in different places in the tank body are different As a result, the anaerobic fermentation is uneven, and the material at the bottom of the tank is prone to sedimentation and separation, and the anaerobic fermentation effect is even more unsatisfactory.

Detailed ways

In the description of the present utility model, it should also be noted that, unless otherwise specified and limited, the terms "setting", "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection , can also be detachably connected, or integrally connected; can be mechanically connected, can also be electrically connected; can be directly connected, can also be indirectly connected through an intermediary, and can be internal communication between two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model in specific situations.

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Embodiment 1: as shown in Fig. 1, Fig. 2, a kind of anaerobic fermentation device comprises pulverizing tank 1, fermentation tank, 2 pulverizing tank tops are provided with the first feed inlet 3, and pulverizing tank bottoms are provided with the first discharge Mouth 4, crushing tank side wall is equipped with pulverizing device, and pulverizing device comprises the motor one 5 that is installed on the pulverizing tank side wall, is installed in the pulverizing shaft 6 that is connected with motor one in the pulverizing tank, and screw blade 7 is installed on the pulverizing shaft 6, through The effect of motor 1 drives the crushing shaft 6 to rotate, so that the spiral blade 7 can crush the stalks. The crushing shaft in this embodiment is arranged obliquely, and the free end of the crushing shaft is the lowest point, facing the first discharge port. This design can The auxiliary crushed straw is sent to the first outlet 3, and then the straw can be better passed to the next step. At the same time, a baffle 20 is installed at the first feeding inlet. This baffle is also installed obliquely. The lowest point is towards the highest point of the crushing shaft 6, so that the straw entering the crushing pool can not only be smoothly conveyed to the screw blade, but also protect the entire crushing shaft, and will not be damaged and crushed due to the straw falling directly on the crushing shaft. shaft life.

There is an air inlet 8 on the top of the fermentation tank, which can assist the crushed straw to enter the fermentation tank more smoothly, and there will be no great pressure. The bottom of the fermentation tank is provided with a second discharge port 9, and the second discharge Port 9 is used to discharge fermented materials, and the bottom of the fermenter is designed in an arc shape. The second outlet 9 is set at the center of the bottom of the fermenter. The arc-shaped design allows materials to be more smoothly concentrated at the second outlet. To facilitate discharge, the upper part of the side wall of the fermenter is provided with a second feed port 10, the lower part of the side wall of the fermenter is provided with a third feed port 11, and a fan 12 is installed at the first discharge port, and the output end of the fan passes through a trident pipe 13 is connected to the second feed port and the third feed port, that is, the first feed port is connected to the second feed port, and the amateur third feed port is connected, while the second feed port and the third feed port It is also connected, the output end of the fan is installed with valve one 14, the second feed port is equipped with valve two 15, the third feed port is installed with valve three, and between valve two and the second feed port is also installed There is a pump body 17. When transporting straw from the crushing pool to the fermentation tank normally, the valve two 15 is closed, and the pump body 17 is also closed at the same time. The straw is sent to the bottom of the fermentation tank 2, and the acid water in the fermentation tank is combined with the straw for fermentation. As the material increases, the liquid level rises. According to the different fermentation conditions, close the valve 14, close the fan 12, and open the valve. Three 16, valve two 15, pump body 17 work, can pump the material in the bottom layer of the fermenter to the upper layer of the fermenter, and then the logistics of the upper layer of the fermenter is reduced to the lower layer, the fermentation is uniform, and the fermentation effect is improved.

The fermenter is equipped with a stirring device near the bottom. The stirring device includes a motor two 18 arranged on the side wall, and also includes a stirring shaft 19 horizontally arranged in the fermenter and connected with the second motor. The assembly includes a dispersing rod 21 evenly distributed on the stirring shaft, a scraper 22 is fixed on the dispersing rod, the dispersing rod is hinged on the stirring shaft, and a vent hole 23 is opened on the scraper, and the stirring shaft will be carried out by the rotation of the motor 218. Rotating can stir the materials in the fermenter more evenly. Since the stirring shaft 19 is relatively close to the third feeding port, the stirring shaft 19 can stir the materials in time. At the same time, the dispersing rod is hinged on the stirring shaft. During the stirring process, the dispersing rod will shake, which will drive the scraper 21 to shake as a whole. The scraper can be in contact with the bottom of the fermentation tank, thereby preventing the material from sticking to the fermentation tank. No vortex will be formed during the process. The section of the stirring shaft is a regular pentagon. The design of the regular pentagon will make the installation of the dispersing rod more stable, because there is a plane on the stirring shaft of the regular pentagon, and the dispersing rod is in contact with the plane. The final installation is convenient and strong. If the stirring shaft is cylindrical, the dispersing rod will shake and not be strong during the installation process due to the existence of the arc surface and work for a long time.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model, All should be included within the protection scope of the present utility model.
