DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the utility model.

[0028] like Figure 1 As shown, the utility model provides a microorganism nest fermentation device for treating poultry manure, including a fermentation tank 1, in which a plurality of partitions 2 are arranged in parallel and equidistantly, and the plurality of partitions 2 divide the fermentation tank 1 into a plurality of fermentation tanks 3 for placing microorganism nests. A plurality of temperature detectors 31 are evenly arranged along a diagonal in each fermentation tank 3, a motor 32 is arranged on the outer wall of each fermentation tank 3, and a turning device 4 is also installed in each fermentation tank 3, and the output end of each motor 32 penetrates the side wall of the fermentation tank 3 and is connected to the turning device 4 one by one. The temperature detector 31 and the motor 32 are electrically connected to the controller 33.

[0029] The microbial nest fermentation device for treating poultry manure and sewage, when working, first needs to lay fillers in each fermentation tank 3, after the fillers are laid, add composite microbial inoculants (i.e. strains) to the fillers, and after the fillers and strains are piled up and fermented for a period of time, a reactor for absorbing manure and sewage will be formed, i.e., a microbial nest. The manure and sewage collected from the livestock and poultry breeding house will be stirred, pulped and homogenized, and then evenly sprayed in the microbial nest, and the microbial nest in the fermentation tank 3 will decompose the manure and sewage, and the microbial nest pile after decomposing the manure and sewage is the best raw material for producing organic fertilizers, which can be sold or piled up to produce organic fertilizers.

[0030] The process of decomposing fecal water by the microbial nest in the fermentation tank 1 takes a long time, so daily maintenance and management of the microbial nest reactor is very important. The maintenance of the microbial nest reactor mainly involves turning it over and managing its temperature. The temperature control is mainly achieved by controlling the amount of fecal water sprayed and turning the microbial nest reactor. In the prior art, the turning work mainly adopts a track-type turning machine, that is, a track is installed above the fermentation tank 1, and the track-type turning machine moves along the track and turns the microbial nest reactor below it. However, due to the large area of ​​the fermentation tank 1 and the slow operation of the track-type turning machine, it is not possible to turn over some of the microbial nest reactors with higher temperatures in the fermentation tank 1 in time, which causes their activity to decrease, thereby reducing their ability to treat fecal water.

[0031] The microbial nest fermentation device for treating poultry manure provided by the utility model divides the fermentation pool 1 into a plurality of fermentation tanks 3 by a partition 2, and an independent turning device 4 is arranged in each fermentation tank 3, and the temperature in the microbial nest reactor is detected in real time by a temperature detector 31. The detection result is transmitted to the controller 33. When the detected temperature is higher than the set value of the controller 33, the controller 33 will control the start of the motor 32, and then turn the microbial nest reactor. Through the synergistic effect between the partition 2, the temperature detector 31, the controller 33, and the turning device 4, the turning efficiency of the microbial nest reactor is improved, thereby improving the efficiency of temperature control of the microbial nest reactor, and also improving the efficiency of the microbial nest in treating fecal water. It should be noted that the probe part of the temperature detector 31 needs to be inserted into the microbial nest reactor at a position below 20 cm.

[0032] like Figure 2 and Figure 3 As shown, further, the tossing device 4 includes a transmission shaft 41, which is arranged along the long axis of the fermentation tank 3, one end of the transmission shaft 41 is connected to the output end of the motor 32, and the other end extends to the end of the fermentation tank 3. A first stirring paddle 42 is arranged in the middle of the transmission shaft 41, and a plurality of second stirring paddles 43 are evenly distributed along the spiral line on both sides of the first stirring paddle 42. The first stirring paddle 42 is a spiral stirring paddle, and the second stirring paddle 43 includes a connecting rod 431 fixedly connected to the transmission shaft 41, and a section of the connecting rod 431 away from the transmission shaft 41 is fixedly connected to a straight rod 432, and a plurality of long teeth 433 and a plurality of short teeth 434 are alternately arranged on the straight rod 432. Further, the plurality of second stirring paddles 43 evenly distributed along the spiral line are arranged in the same or opposite spiral directions.

[0033] The transmission shaft 41 is arranged along the long side of the fermentation tank 3, and both ends need to extend to the end of the fermentation tank 3, so as to ensure that the materials in each place can be turned over. Two different types of stirring paddles are arranged on the transmission shaft 41 to improve the turning effect of the turning device 3 on the microbial nest reactor (hereinafter referred to as the pile). The first stirring paddle 42 is arranged in the style of a spiral stirring paddle, and the midpoint of the spiral direction transmission shaft 41 on the first stirring paddle 42 is symmetrically arranged, so that the pile in the fermentation tank 3 can be transferred from the middle to both sides or from both sides to the middle by controlling the output direction of the motor 32. A second stirring paddle 43 is arranged, and a plurality of alternating long teeth 433 and short teeth 434 are arranged on the straight rod 432 of the second stirring paddle 43 to break up the compacted pile and make it better dispersed.

[0034] like Figure 2 and Figure 4 As shown, further, an independent spraying mechanism 5 is also provided above each fermentation tank 3, and the spraying mechanism 5 includes a manure water spraying device 51 and a bacterial strain spraying device 52. Further, each manure water spraying device 51 includes a manure water conveying pipeline 511 and a plurality of manure water spraying heads 512 connected to the manure water conveying pipeline 511, and a first solenoid valve 513 is installed on the manure water conveying pipeline 511. Each bacterial strain spraying device 52 includes a bacterial strain conveying pipeline 521 and a plurality of bacterial strain spraying heads 522 connected to the bacterial strain conveying pipeline 521. The plurality of manure water spraying heads 512 and the plurality of bacterial strain spraying heads 522 are arranged in the same plane and are spaced apart from each other. Further, the first solenoid valve 513 is also electrically connected to the controller 33.

[0035] The manure water spraying device 51 is used to add manure water to the fermentation tank 3. Its functions are to complete the daily decomposition of manure water and to reduce the temperature of the pile. The bacterial strain spraying device 52 adds bacterial strains to the pile according to the indicators to ensure that the pile's ability to decompose manure water does not decrease. Both spraying should be evenly sprayed on the surface of the pile, and then turned over by the turning device 3 to ensure that the manure water and bacterial strains are evenly distributed. The utility model arranges multiple manure water spray heads 512 and multiple bacterial strain spray heads 522 on the same plane and arranges them at intervals from each other, which ensures that when spraying manure water or bacterial strains, they can be evenly distributed on the surface of the pile, thereby improving the working efficiency of the fermentation process.

[0036] The first solenoid valve 513 is also electrically connected to the controller 33, that is, the opening of the first solenoid valve 513 is controlled according to the detection result of the temperature detector 31 on the pile temperature, and then the spraying amount of the manure water is determined: when the temperature is near the set value, the manure water is sprayed according to the normal daily processing amount. When the detected temperature is lower than the lower limit of the set temperature, the spraying amount of the manure water is reduced to reduce the loss of the pile temperature. When the detected temperature is higher than the upper limit of the set temperature, the spraying amount of the manure water is increased to reduce the temperature of the pile. By adjusting the spraying amount of the manure water, the temperature of the pile is regulated to ensure the efficiency of the pile in decomposing the manure water.

[0037] like Figure 6 As shown, further, a heat exchange tube 34 is laid in an S shape at the bottom of each fermentation tank 3, and a three-way joint 35 is installed at the inlet end of each heat exchange tube 34. The two inlet ends of the three-way joint 35 are respectively connected to the hot water storage tank 36 and the cold water storage tank 37, and the outlet end of each heat exchange tube 34 is connected to the recovery water tank 38. A second solenoid valve 351 is respectively installed between the hot water storage tank 36, the cold water storage tank 37 and each three-way joint 35, and a third solenoid valve 352 is respectively installed between the outlet end of each heat exchange tube 34 and the recovery water tank 38. Each second solenoid valve 351 is electrically connected to the controller 33.

[0038] An S-shaped heat exchange tube 34 is laid at the bottom of the fermentation tank 3. By adding cold water or hot water to the heat exchange tube 34 and cooperating with the turning device 4, the efficiency of temperature control of the pile can be improved, thereby maintaining the stability of the daily manure treatment volume.

[0039] like Figure 5 and Figure 6 As shown, further, a waterproof layer 6 is arranged above the heat exchange tube 34 in each fermentation tank 3, and the waterproof layer 6 is laid at an angle. A drainage groove 61 is opened at the connection between the inclined lower end of each waterproof layer 6 and the fermentation tank 3, and a drainage groove 62 is arranged at the lower side of the drainage groove 61, and the end of the drainage groove 62 is connected to the wastewater tank 63.

[0040] The inclined waterproof layer 6 is provided to firstly avoid the corrosion of the heat exchange tube 34 by the manure, and secondly the excess manure can flow along the inclined waterproof layer 6 through the drainage groove 61 into the drainage ditch 62, and then flow along the drainage ditch 62 into the wastewater pool 63 for collection and treatment. After the excess manure is drawn out, it is beneficial to the fermentation of the pile.

[0041] Furthermore, a plurality of moisture detectors are evenly arranged along another diagonal in each fermentation tank 3 .

[0042] The microbial nest has a flexible renewal cycle and can be used for more than two years. The moisture content is tested by a moisture detector. When the moisture content reaches more than 70%, the microbial nest needs to be renewed, the old filler is removed and new filler is added.

[0043] The present invention is further described in detail below in conjunction with specific embodiments.

The detection result is transmitted to the controller 33, and when the detected temperature is higher than the set value of the controller 33, the controller 33 will control the start of the motor 32, and then turn the microbial nest reactor. Through the synergistic effect of the partition 2, the temperature detector 31, the controller 33, and the turning device 4, the turning efficiency of the microbial nest reactor is improved, thereby improving the efficiency of the temperature control of the microbial nest reactor and improving the efficiency of the microbial nest in treating fecal water.

[0048] The manure water spraying device 51 is used to add manure water to the fermentation tank 3. Its functions are to complete the daily decomposition of manure water and to reduce the temperature of the pile.
