Description

Technical Field

[0001] This utility model relates to the technical field of equipment for the harmless treatment of livestock and poultry manure, specifically an aerobic fermentation device suitable for the harmless treatment of livestock and poultry manure. Background Technology

[0002] Currently, the most commonly used methods for treating livestock and poultry manure in China are aerobic composting and anaerobic fermentation. Aerobic composting is low-cost and easy to operate. It uses oxygen to allow microorganisms to decompose organic matter, thereby reducing the amount of manure, killing pathogens, reducing odor, and producing by-products that can be used as fertilizer or energy.

[0003] During the fermentation of livestock and poultry manure, the manure usually contains a certain amount of residual liquid. When there is a lot of residual liquid, it will reduce the porosity of the pile, reduce air circulation, and lead to oxygen deficiency inside the pile. Under anaerobic conditions, microbial activity is restricted, the fermentation speed slows down, and it may even lead to anaerobic fermentation in some areas, producing foul-smelling gases, thereby reducing fermentation efficiency and resulting in poor fermentation effect. Utility Model Content

[0004] The purpose of this invention is to provide an aerobic fermentation device suitable for the harmless treatment of livestock and poultry manure, which has the advantage of being able to separate and collect residual liquid in livestock and poultry manure, thus solving the problem that residual liquid in livestock and poultry manure affects the fermentation effect during the fermentation process.

[0005] This utility model is achieved through the following technical solution: an aerobic fermentation device suitable for the harmless treatment of livestock and poultry manure, the main body of which is a fermentation box, and a material holding box is provided inside the fermentation box; four side blocks are fixedly connected to the inner side wall of the fermentation box, and a tension spring is fixedly fixed to the top of the side blocks, and the top of the tension spring is fixedly connected to the bottom of the material holding box; multiple drainage channels are opened on the bottom surface of the material holding box, and a filter screen is fixedly connected to the top surface of each drainage channel;

[0006] The fermentation tank is rotatably connected to a driven shaft extending in the left-right direction. The driven shaft is located below the material container, and multiple regularly arranged cams are fixedly connected to the driven shaft. The cams abut against the bottom surface of the material container.

[0007] The fermentation tank is equipped with a stirring rod and a fermentation structure. The top end of the stirring rod is rotatably connected to the fermentation tank, and the bottom end of the stirring rod is rotatably connected to the material container. The top of the fermentation tank is equipped with a driving structure, which is connected to the stirring rod and the driven shaft respectively.

[0008] A liquid storage tank is fixedly connected to the bottom of the fermentation box, and a liquid outlet pipe is connected to the liquid storage tank. The end of the liquid outlet pipe extends out of the fermentation box and a valve is installed at the end of the liquid outlet pipe. A feeding door is hinged to the top of the fermentation box, and a material removal door is hinged to the side of the fermentation box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, the drive structure can drive the stirring rod to rotate and stir, so that the feces can be turned over inside the holding box. At the same time, the driven shaft will also drive the cam to rotate together, so that the cam can continuously push the holding box to move up and down, thereby achieving the effect of the feces shaking up and down inside the holding box, so that the residual liquid in the feces can be quickly separated from the feces during the movement, and flow into the liquid storage tank through the liquid drainage channel on the surface of the holding box.

[0011] 2. This utility model can also utilize the effects of stirring and shaking to improve the air permeability of the manure pile, ensuring that oxygen can better penetrate into the interior of the manure pile, promoting the activity of aerobic microorganisms, accelerating the fermentation speed, and reducing the moisture content of the manure, thereby reducing problems such as hypoxia and odor caused by high moisture content and improving fermentation efficiency.

[0018] Please see Figure 1-5 An aerobic fermentation device suitable for the harmless treatment of livestock and poultry manure is provided. The main body is a fermentation box 1, and a material holding box 2 is provided inside the fermentation box 1. Four side blocks 3 are fixedly connected to the inner wall of the fermentation box 1. A tension spring 4 is fixedly connected to the top of the side blocks 3. The top of the tension spring 4 is fixedly connected to the bottom of the material holding box 2. Multiple drainage channels are opened on the bottom surface of the material holding box 2, and a filter screen 5 is fixedly connected to the top surface of each drainage channel.

[0019] The fermentation tank 1 is rotatably connected to a driven shaft 10 extending in the left and right direction. The driven shaft 10 is located below the material container 2, and multiple regularly arranged cams 11 are fixedly connected to the driven shaft 10. The cams 11 abut against the bottom surface of the material container 2.

[0020] The fermentation tank 1 is equipped with a stirring rod 12 and a fermentation structure. The top end of the stirring rod 12 is rotatably connected to the fermentation tank 1, and the bottom end of the stirring rod 12 is rotatably connected to the material container 2. The top of the fermentation tank 1 is equipped with a driving structure, which is connected to the stirring rod 12 and the driven shaft 10 respectively.

[0021] The bottom of the fermentation tank 1 is fixedly connected to a liquid storage tank 6, the liquid storage tank 6 is connected to a liquid outlet pipe, the end of the liquid outlet pipe extends out of the fermentation tank 1 and a valve 7 is installed at the end of the liquid outlet pipe; the top of the fermentation tank 1 is hinged to a feeding door 8; the side of the fermentation tank 1 is hinged to a material removal door 9.

[0022] It should be noted that manure can be fed into the container 2 through the feeding door 8. The fermentation structure is used to adjust the temperature and humidity inside the fermentation chamber 1 to meet the fermentation requirements of the manure. The drive structure can rotate the stirring rod 12, causing the manure to tumble inside the container 2. During this process, the driven shaft 10 will also rotate the cam 11, causing the cam 11 to continuously push the container 2 up and down. At the same time, the tension spring 4 will stretch and rebound to ensure that the bottom of the container 2 is in contact with the surface of the cam 11. As the container 2 moves up and down, the manure will also sway up and down. This process allows residual liquid in the manure to be quickly separated from the manure during operation, and flows into the storage tank 6 through the drainage channel on the surface of the material container 2. The filter screen 5 can intercept the manure, and opening the valve 7 can discharge the liquid accumulated inside the storage tank 6. Through this combination of turning and up-and-down movement, the permeability of the manure pile can be improved, ensuring that oxygen can better penetrate into the manure pile, promoting the activity of aerobic microorganisms, accelerating the fermentation speed, and reducing the moisture content of the manure. This reduces problems such as hypoxia and odor caused by high moisture content, and improves fermentation efficiency. The fermented manure can then be taken out from inside the material container 2 by opening the material access door 9.

[0023] Furthermore, the fermentation structure includes a heating plate 24 and a temperature and humidity sensor 25. The heating plate 24 is fixedly connected to the inner wall of the fermentation chamber 1, and the temperature and humidity sensor 25 is located above the heating plate 24.

[0024] Multiple water supply pipes 23 are fixedly connected to the inner side of the top of the fermentation tank 1. The top of each water supply pipe 23 is connected to a liquid addition pipe, the tip of which extends through the top of the fermentation tank 1. It should be noted that a controller is fixed to the back of the fermentation tank 1. The controller is electrically connected to a temperature and humidity sensor 25 and a heating plate 24. The temperature and humidity sensor 25 monitors the temperature and humidity inside the fermentation tank 1 and transmits signals to the controller. The controller then operates the heating plate 24 to adjust the temperature inside the fermentation tank 1. Water can be added to the water supply pipes 23 via the liquid addition pipes, allowing for water addition to the fermentation tank 1 and thus changing the humidity inside the fermentation tank 1.

[0025] Furthermore, the side wall of the fermentation box 1 is provided with an exhaust duct, and a fan 22 is fixedly connected to the exhaust duct.

[0026] It should be noted that the blower 22 can ensure ventilation inside the fermentation tank 1, so that the manure can meet the fermentation conditions.

[0027] Furthermore, the drive structure includes a drive motor 13 and a bearing housing 14. Both the drive motor 13 and the bearing housing 14 are fixedly connected to the top of the fermentation tank 1, and the output shaft of the drive motor 13 is fixed with a drive shaft 15, which passes through the bearing housing 14.

[0028] A first bevel gear 161 is sleeved and fixed on the drive shaft 15; a second bevel gear 162 is fixedly connected to the top of the stirring rod 12, and the first bevel gear 161 meshes with it.

[0029] A transmission assembly is connected to the right end of the drive shaft 15.

[0030] It should be noted that when the drive motor 13 starts, it can drive the drive shaft 15 to rotate. The drive shaft 15 can then drive the driven shaft 10 to rotate together through the transmission assembly. At the same time, the meshing of the bevel gear 16 on the surface of the drive shaft 15 and the bevel gear 16 on the surface of the stirring rod 12 also allows the stirring rod 12 to rotate simultaneously, thus ensuring that the stirring rod 12 and the driven shaft 10 can move.

[0031] Furthermore, the transmission assembly includes pulleys 17, with two pulleys 17 spaced apart vertically and located outside the fermentation tank 1;

[0032] The upper pulley 17 is fixedly connected to the right end of the drive shaft 15 as the driving gear, and the lower pulley 17 is fixedly connected to the right end of the driven shaft 10 as the driven gear; a belt is connected between the two pulleys 17 for transmission.

[0033] It should be noted that when the drive shaft 15 rotates, the upper pulley 17 will drive the lower pulley 17 to rotate synchronously through the belt, so that the cam 11 can rotate simultaneously with the drive shaft 15.

[0034] Furthermore, a material guide frame 18 is fixedly connected to the inner wall of the fermentation box 1. The top surface of the material guide frame 18 is an inclined surface that slopes from the outside to the inside. A vertically arranged rectangular corrugated pipe 19 is fixedly connected to the bottom end of the inclined surface. The bottom of the rectangular corrugated pipe 19 is fixedly connected to the top of the material container 2.

[0035] It should be noted that the guide frame 18 can guide the falling manure, allowing it to slide down into the holding box 2 through the inclined design. The rectangular corrugated pipe 19 can extend and retract, and it can also block the manure, preventing it from falling into the liquid storage tank 6 through the gap between the holding box 2 and the guide frame 18.

[0036] Furthermore, the inner wall of the fermentation box 1 is fixed with a plurality of vertically arranged guide rails 20, and the outer wall of the material container 2 is fixedly connected with a plurality of sliders 21, which are slidably connected to the corresponding guide rails 20.

[0037] It should be noted that when the container 2 is pushed up and down by the cam 11, the slider 21 will slide along with the container 2 on the surface of the guide rail 20, so that the container 2 can be guided up and down, and avoid the container 2 from moving back and forth.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
