Detailed Description

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the horizontal rotary fermentation chamber mainly comprises a feeding unit 100, a fermentation tank 200, a driving unit 201 and a discharging unit 300. The method comprises the steps of firstly treating the manure through the feeding unit 100, conveying the treated manure into the fermentation tank 200, fermenting the manure in the fermentation tank 200, and outputting the fermented manure through the discharging unit 300 for subsequent production and cultivation.

The feeding unit 100 of the horizontal rotary fermentation chamber according to the present embodiment includes a solid-liquid separator 101, a buffer tank 102, a first conveyor 103, and a feeding auger 104. Wherein, the solid-liquid separator 101 can effectively separate the solid material and the liquid material in the manure, and the solid material separated from the liquid material is delivered to the fermentation tank 200. An auger type pusher is arranged at a feed inlet of the buffer tank 102 to prevent the accumulation of materials, a first conveying device 103 is arranged at the bottom of the buffer tank 102, and the first conveying device 103 can be conveyed by an auger or a conveying belt, namely the conveying belt in the embodiment. The first conveyor 103 can push the manure to the feeding auger 104. As the manure contains a large amount of high-fiber substances, the feeding auger 104 can prevent the blockage of the materials, and the feeding auger 104 is connected with the feeding port of the fermentation tank 200 to push the manure into the fermentation tank 200 for fermentation.

Example 1

The first transportation mode of the feeding unit 100 of the horizontal rotary fermentation chamber according to the present embodiment is as shown in fig. 1, and the order of placing the devices along the transporting direction of the manure is as follows: solid-liquid separator 101 → buffer tank 102 → first conveying device 103 → feeding auger 104. Firstly, the manure is dehydrated by the solid-liquid separator 101, the dehydrated manure falls into the feed inlet of the buffer tank 102 from the discharge port of the solid-liquid separator 101, is transported to the feed inlet of the feed auger 104 through the first conveying device 103 at the bottom of the buffer tank 102, and is then pushed into the fermentation tank 200 through the feed auger 104. In the first transportation mode, once the solid-liquid separator 101 has a fault and cannot be used normally, excrement can be directly poured into the buffer tank 102, so that feeding can be performed, and sufficient excrement can be fermented in the fermentation tank 200, so that the horizontal rotary fermentation cabin can be ensured to continue to operate without stopping.

As shown in fig. 3 to 6, the fermentation tank 200 of the horizontal rotary fermentation chamber according to the present embodiment is a horizontal rotary fermentation tank, and the tank mouths at both ends thereof are connected to a feed screw 104 and a discharge screw 301, respectively. The tank of the fermenter 200 is cylindrical in its entirety and has two large flanges 21, by means of which two large flanges 21 can be brought into contact with the adaptive drive system at the bottom of the fermenter 200. The self-adaptive driving system is composed of a controller and four driving units 201, the driving units 201 are mainly provided with rollers 11, an overrunning clutch 12 and a speed reducing motor 13, and the four rollers 11 are rotatably arranged on a base to support the fermentation tank 200. The roller 11 is connected with an overrunning clutch 12, and the overrunning clutch 12 is connected with (an output shaft of) a speed reducing motor 13. The overrunning clutch 12 is an important component between the roller 11 and the speed reducing motor 13, and can be used for power transmission and separation functions between the roller 11 and the speed reducing motor 13, the speed reducing motor 13 drives the roller 11 to rotate through the overrunning clutch 12, and meanwhile, the overrunning clutch 12 is arranged, so that the rotating speed of the roller 11 is allowed to be greater than that of an output shaft of the speed reducing motor 13. For example, when the fermentation tank 200 needs to rotate clockwise, the controller controls the decelerating motors 13 to drive the fermentation tank 200 to rotate clockwise through the overrunning clutch 12, and when one or two decelerating motors 13 stop operating, the fermentation tank 200 can continue to rotate clockwise under the drive of the other decelerating motors 13.

The fermentation tank 200 is driven by a self-adaptive driving system, four driving units 201 are respectively arranged at two sides of the bottom of the fermentation tank 200, are arranged in a pairwise opposite mode, and are in friction contact transmission with a large flange 21 on the fermentation tank 200 through rollers 11, so that the rollers 11 drive the fermentation tank 200 to rotate. When the fermentation tank 200 is started, a large starting torque is required to drive the fermentation tank 200 to rotate, and therefore, in the present embodiment, the fermentation tank 200 is rotated by simultaneously operating the four driving units 201 (four speed reducing motors 13), and the power of the speed reducing motors 13 is transmitted to the rollers 11 through the overrunning clutch 12, so that the rollers 11 drive the fermentation tank 200 to rotate. When the fermenter 200 is operated, the rotational torque is reduced, and it is no longer necessary to operate the four driving units 201 at the same time, and it is possible to stop operating two of the driving units 201 and continue operating the remaining two driving units 201. After the speed reducing motor 13 stops running, the roller 11 can continue to rotate without being influenced by the speed reducing motor 13 through the power separation function of the overrunning clutch 12. The roller 11 and the large flange 21 are in friction transmission and can be driven by the rotating fermentation tank 200 to further continue rotating.

The controller can control any two of the four driving units 201 to respectively operate, so that the intermittent motion of the speed reducing motor 13 is realized, and the service life of the speed reducing motor 13 is prolonged. Depending on the increase of manure fed into the fermentation tank 200 or the increase of the turning moment of the fermentation tank 200, it is possible to switch from operating two drive units 201 to three or four drive units 201. In addition, the controller monitors the current of the four speed reducing motors 13 in real time, so that the running state of the speed reducing motors 13 can be found in time, and once the speed reducing motors 13 are found to have faults, the controller can give an alarm in time.
