Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Referring to fig. 1 and 2, an aerobic fermentation apparatus according to a preferred embodiment of the present invention is used for aerobic fermentation of sludge, and includes a box 100, a feeding port 1 disposed at an upper portion of one end of the box 100, a discharging port 9 disposed at a lower portion of the other end of the box 100, an aeration assembly disposed at a bottom of the box 100, and an exhaust duct 6 disposed at a top of the box 100, and further includes two parallel gears 2 disposed at two ends of the interior of the box 100, a link plate 8 connecting the two parallel gears 2, and a motor 7 for driving the link plate 8 to rotate. The inside link joint 8 that is provided with of fermentation box 100, mud are placed and are fermented on link joint 8, and box 100 and link joint 8 are longer than current fermentation cylinder in the shape, and the volume is bigger, once can ferment more mud, through the fermentation of several days cycle, mud is loose form, moisture content greatly reduced, the ejection of compact after the fermentation is accomplished.

The chain plates 8 are driven by a chain, the parallel gears 2 are arranged at two ends of the box body 100, and the chain plates 8 are arranged between the two parallel gears 2 and driven by the motor 7 to operate. The chain transmission has many advantages, compared with the belt transmission, the chain transmission has no elastic sliding and slipping phenomena, the average transmission ratio is accurate, the work is reliable, and the efficiency is high; the transmission power is large, the overload capacity is strong, and the transmission size under the same working condition is small; the required tension is small, and the device can work in severe environments such as sludge, moisture, dustiness, pollution and the like.

Referring to fig. 3, the aeration assembly of the present embodiment includes an air inlet pipe 51 disposed between the upper and lower chain plates 8, and a fan 52 connected to the air inlet pipe 51, wherein the air inlet pipe 51 is provided with a small hole (not shown) for air to flow out. The invention can also be realized by adopting the aeration component in the prior art. To enhance aeration, the fan 52 is preferably a turbo fan 52.

In order to improve the sludge treatment capacity, the box body 100 of the invention is longer, the box body 100 comprises a plurality of cabin bodies 101 which are arranged in sequence, and the bottom of each cabin body 101 is provided with a closed funnel 9. In the process of the movement of the chain plate 8, a small amount of sludge is sprinkled into the bin body 101, and the spilled sludge can be taken out by opening the hopper 9.

For the uniform fermentation of the sludge, a material turning and throwing component 3 is arranged in the middle of each bin body 101. Specifically, the material turning and throwing assembly 3 includes a propeller (not shown in the figure) and a motor (not shown in the figure) driving the propeller.

In order to reduce the spill during feeding, the feed inlet 1 is a funnel 9 type feed inlet 1. In order to prevent the waste gas generated during the fermentation process from escaping from the box 100, a gate (not shown) is disposed at the feeding port 1, and the gate is opened when the feeding is performed and closed when the feeding is finished.

In order to evenly distribute the sludge on the chain plate 8, a feeding distribution assembly 11 is arranged between the feeding hole 1 and the chain plate 8, and the feeding distribution assembly 11 comprises a coaxial counter-rotating propeller and a motor driving the coaxial counter-rotating propeller. Due to the heavy weight of the sludge, the motor 7 is preferably a hydraulic motor 7, the hydraulic motor 7 being able to provide a large power.

In order to accurately know the sludge fermentation condition, a temperature and humidity detection assembly 4 and a controller (not shown in the figure) electrically connected with the temperature and humidity detection assembly 4 are arranged in the box body 100; the controller controls the aeration amount of the aeration component according to the data detected by the temperature and humidity detection component 4, and when the temperature is high or the humidity is high, the controller commands the fan 52 to rotate at a high speed to convey more air and improve the aeration amount; when the temperature is high or the humidity is low, the controller commands the fan 52 to rotate at a low speed, so that less air is delivered and the aeration rate is reduced.

As the box body 100 and the chain plate 8 are longer, the feeding is interrupted, the chain plate 8 runs intermittently, the sludge near the feeding hole 1 is at the beginning of the fermentation period, the sludge is distributed on the chain plate, the sludge near the discharging hole 9 is at the end of the fermentation period, and the sludge at the end of the fermentation is discharged intermittently by taking each bin body 101 as a unit. Alternatively, in the case where the box 100 and the chain plate 8 are long enough, the aerobic fermentation apparatus of the present invention can be continuously operated without interruption.

The working process of the aerobic fermentation equipment comprises the steps of firstly, adding auxiliary materials and microorganism zymogens into sludge to be treated, then feeding the sludge into the equipment through a feeding hole 1, and then closing a flashboard; secondly, under the action of the feeding distribution component 11, sludge is uniformly distributed on the chain plate 8, the sludge is supported by the chain plate 8 in the equipment, the chain plate 8 drives the sludge to integrally move in a chain transmission mode, and then the material is turned loose under the action of the material turning component 3; meanwhile, small holes are formed in the air inlet pipe 51 between the chain plates 8, air output by the fan 52 enters the space between the chain plates 8 through the small holes of the air inlet pipe 51, and the air is aerated into the sludge material to provide enough oxygen for microbial fermentation; finally, the waste gas generated by fermentation is discharged through an exhaust duct 6 arranged at the top of the box body 100, and the chain plate 8 rotates to discharge the sludge from a discharge hole 9; after several days of fermentation, the sludge is loose, under the action of continuous aeration, water and waste gas are discharged together through the exhaust pipeline 6, the water content of the sludge is greatly reduced, and aerobic fermentation is completed.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
