detailed description

The specific implementation of the utility model is described in conjunction with the examples.

As shown in Figure 1, an integrated biogas generating device includes multiple parallel fermentation chambers 1, each fermentation chamber 1 is provided with a feed inlet and an air outlet pipe 3 at the top, a slag outlet 5 at the bottom, and sensors installed on the inner wall 4. Each fermentation chamber is connected in parallel through common inlet and outlet pipes and air outlet pipes. The feed inlet is connected with a feed control device 11, and the feed control device 11 controls feeding according to the height of the material in the fermentation chamber 1 monitored by the sensor 4. When the material height in the fermentation chamber 1 reaches the height where the sensor 4 is located, the feeding is stopped.

There is an impeller agitator inside the fermentation chamber 1, and the impeller agitator includes a plurality of paddles 2 arranged on a vertical plane, the paddles 2 are installed on a central shaft, and the central shaft is connected with the impeller agitator power motor 12 The impeller agitator power motor 12 is installed on a vertical support 10, and the support 10 is fixed at the center of the bottom of the fermentation chamber 1. The impeller agitator mainly stirs in the vertical direction, that is, it can turn over the materials in the bottom and upper parts of the fermentation chamber 1, fully provide oxygen for the materials in the fermentation chamber 1, and improve the efficiency of microbial biogas growth.

Also includes a horizontal agitator, the horizontal agitator includes a hollow shaft 7, the hollow shaft 7 is sleeved on the outside of the support 10, and is connected with the power motor 9; in the fermentation chamber 1, the hollow shaft 7 is connected with a conical guide plate 8, the conical guide plate 8 is a conical platform structure, and a plurality of stirring rods 6 are installed on the side of the conical platform. The horizontal agitator is mainly used to agitate the material feed in the horizontal direction to achieve uniform mixing. It can be used alone in the anaerobic stage, or it can be used together with the vertical impeller agitator in the aerobic stage.

The conical guide plate 8 is located below the paddle 2, and the stirring rod 6 is symmetrically installed on the periphery of the paddle 2, and the conical guide plate 8 and the stirring rod 6 are both located outside the range of motion of the paddle 2. This arrangement is mainly to avoid mutual interference of the two stirring devices. The conical guide plate 8 has two main functions, one is to prevent the material from gathering near the hollow shaft 7 and cannot be fully stirred, and the other function is to facilitate material discharge, because the conical guide plate 8 is inclined from the center to the surrounding, the material is in the It is discharged to the side wall of the fermentation chamber 1 under centrifugal action, and is discharged from the slag outlet 5.

The stirring rod 6 is an arc structure, and the center of the circle where the arc is located coincides with the central axes of the paddles 2 . The arc-shaped stirring rod structure can increase the stirring capacity of the stirring rod, and the contact area of the stirring rod during the circular motion is larger. And it surrounds the outer circumference of the paddle 2, and plays a synergistic stirring effect with the impeller agitator.
