Description

Technical Field

[0001] This invention relates to the field of manure fermentation technology, specifically to an anaerobic fermentation device for livestock and poultry manure. Background Technology

[0002] Anaerobic fermentation decomposes organic matter through the action of microorganisms in an oxygen-free environment. Using anaerobic fermentation technology, organic matter in poultry manure can be degraded and transformed into usable resources. Anaerobic fermentation not only reduces the volume of poultry manure but also produces biogas. Biogas, as a clean energy source, can reduce environmental pollution. Anaerobic fermentation devices typically include a stirring device, which needs to move while stirring to improve fermentation efficiency. For example, Chinese utility model patent application number "CN202423156359.6" provides an anaerobic fermentation device for poultry manure. In use, the device uses a rotating shaft, lead screw, second belt, and splined shaft to drive the stirring drum and stirring rod to rotate. Simultaneously, the lead screw, through the cooperation of a sliding block, connecting rod, ring, and limiting ring, drives the stirring drum to slide longitudinally, achieving longitudinal stirring.

[0003] The drawback of this device is that the top of the lead screw extends beyond the top surface of the sealing cover. In order to ensure that the lead screw can move normally, a long strip-shaped clearance is set on the top surface of the sealing cover. Therefore, the biogas produced in the fermentation tank will leak out from the top surface of the sealing cover, resulting in the waste of biogas. Summary of the Invention

[0004] The purpose of this invention is to provide an anaerobic fermentation device for livestock and poultry manure. Neither the supporting component nor the stirring component extends outside the sealing cover during operation. The first driving component and the second driving component work together to drive the supporting component and the stirring component to move in two directions to complete the stirring work. The sealing cover has good sealing performance with the fermentation tank, so biogas will not leak out and can prevent the waste of biogas.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anaerobic fermentation device for livestock and poultry manure, comprising: a fermentation tank, the top of which is provided with a sealing cover; a support component, disposed inside the fermentation tank and capable of moving in a horizontal plane; and a stirring component, disposed inside the support component, the tops of both the support component and the stirring component being lower than the inner top surface of the sealing cover.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-12This invention provides a technical solution: an anaerobic fermentation device for livestock and poultry manure, comprising a fermentation tank 1, a sealing cover 2, a supporting component 3, and a stirring component 4. The sealing cover 2 has an inlet pipe and an outlet pipe at both ends, allowing livestock and poultry manure to enter the fermentation tank 1 through the inlet pipe and the biogas produced during fermentation to be discharged through the outlet pipe. In use, the livestock and poultry manure is first transported into the fermentation tank 1, and then the stirring component 4 operates to agitate the manure, improving fermentation efficiency. During this process, the supporting component 3 moves horizontally, thereby driving the stirring component 4 to move horizontally, expanding the stirring range. Since the tops of both the supporting component 3 and the stirring component 4 are lower than the inner top surface of the sealing cover 2, neither component extends beyond the outer side of the sealing cover during operation. The sealing cover 2 has good sealing between itself and the fermentation tank 1, ensuring that biogas can only be discharged through the outlet pipe and will not leak out, thus preventing biogas waste.

[0019] Example 1

[0020] Please see Figure 1-5 and Figure 11 The invention also includes a first driving assembly 5. In this embodiment, the first driving assembly 5 includes a motor, a threaded rod, a driving block, an adjusting rod, and a guide rod. The threaded rod and the guide rod are respectively disposed in receiving grooves on the inner walls of both sides of the fermentation tank 1. The adjusting rod is arranged along the width direction of the fermentation tank 1, and the bearing assembly 3 can slide along the outer surface of the adjusting rod. When the first driving assembly 5 is working, the motor drives the threaded rod to rotate forward or reverse, thereby driving the driving block to move forward or backward. The driving block drives the bearing assembly 3 and the stirring assembly 4 to move together along the length extension direction of the fermentation tank 1 through the adjusting rod. During this process, the adjusting rod slides along the outer surface of the guide rod, increasing the stability of the adjusting rod's movement.

[0021] Please see Figure 1-5 and Figure 12 The invention also includes a second driving assembly 6. In this embodiment, the second driving assembly 6 includes a support frame, an electric telescopic rod, and a top block. There are two second driving assemblies 6, respectively located on both sides of the supporting assembly 3, and their structures are mirror-symmetrical. When the second driving assembly 6 is working, the electric telescopic rod on one side extends, and the electric telescopic rod on the other side shortens. When the top block contacts the inner wall of the fermentation tank 1, it can push the supporting assembly 3 and the stirring assembly 4 to move together along the width extension direction of the fermentation tank 1. During this process, the supporting assembly 3 slides along the outer surface of the adjusting rod, increasing the stability of the movement of the supporting assembly 3.

[0022] Please see Figure 1-5 and Figure 10The stirring component 4 includes an elastic sheet 41 and a transmission component 42. When the supporting component 3 moves in the horizontal plane, the supporting component 3 drives the elastic sheet 41 to move together through the transmission component 42. After contacting livestock and poultry manure, the elastic sheet 41 can undergo elastic deformation, completing the oscillation during the storage and release of elastic potential energy, further enhancing the stirring effect and improving the fermentation efficiency.

[0023] Example 2

[0024] Based on Example 1, please refer to Figure 1-7 An adjusting block 7 is fixedly installed on the inner top surface of the sealing cover 2, and several arc-shaped blocks 71 are provided at the bottom of the adjusting block 7. The bearing assembly 3 includes a first bearing frame 31, a second bearing frame 32, and a spring 33. The bottom surface of the second bearing frame 32 is provided with an insertion rod 321, which is located in the insertion hole of the first bearing frame 31. During the process of the bearing assembly 3 and the stirring assembly 4 moving together along the length extension direction of the fermentation tank 1, the transmission member 42 slides along the surface of several arc-shaped blocks 71. When the transmission member 42 slides downward along the surface of the arc-shaped blocks 71, the transmission member 42 and the elastic sheet 41 tilt to one side. The arc-shaped blocks 71 can apply a downward force to the transmission member 42, and the transmission member 42 drives the second bearing frame 32 and the elastic sheet 41 to move downward together. At this time, the insertion rod 321 slides downward along the inner wall of the insertion hole, and the spring 33 is compressed to store elastic potential energy. When the transmission member 42 slides upward along the surface of the arc-shaped blocks 71, the transmission member 42 and the elastic sheet 41 tilt to the other side. Spring 33 releases its elastic potential energy and extends, causing the second support frame 32, elastic sheet 41, and second support frame 32 to move upward together. Through the cooperation of adjustment block 7 and support component 3, elastic sheet 41 can move vertically and tilt in different directions, improving the stirring effect of elastic sheet 41.

[0025] Please see Figure 3-4 , Figure 6-8 and Figure 10The top of the transmission component 42 is provided with a spherical block 421, through which the transmission component 42 contacts the adjusting block 7. When the transmission component 42 slides upward or downward along the surface of the arc-shaped block 71, due to the large friction between the spherical block 421 and the arc-shaped block 71, the spherical block 421 will rotate, thereby causing the transmission component 42 and the elastic sheet 41 to tilt. An arc-shaped groove 72 is provided between two adjacent arc-shaped blocks 71, and a smooth protrusion 73 is provided at the bottom of the arc-shaped block 71, with the protrusion 73 smoothly transitioning to the arc-shaped block 71. When the spherical block 421 moves between two adjacent arc-shaped blocks 71, it will enter the arc-shaped groove 72. At this time, the spherical block 421 does not contact the side wall of the arc-shaped block 71, and the friction force on the spherical block 421 is small, allowing it to automatically return to a vertical state. When the spherical block 421 continues to slide downward along the surface of the arc-shaped block 71, it will move to the outer surface of the protrusion 73. When the spherical block 421 moves to the bottom of the protrusion 73, due to the small friction between the spherical block 421 and the protrusion 73, the spherical block 421 can still automatically return to a vertical position. Therefore, by cooperating with the adjusting block 7 and the supporting component 3, the number of times the elastic sheet 41 tilts can be increased, thereby improving the stirring effect of the elastic sheet 41.

[0026] Please see Figure 3-8 The width of the arc-shaped blocks 71 at both ends and in the middle of the sealing cover 2 is smaller than the width of the arc-shaped blocks 71 at other locations. Therefore, when the spherical block 421 moves to either end or the middle of the sealing cover 2, the displacement generated by the rotation and tilting of the elastic sheet 41 is greater. Conversely, when the spherical block 421 moves to other locations, the displacement generated by the rotation and tilting of the elastic sheet 41 is smaller. This ensures that livestock and poultry manure can be more thoroughly mixed when the mixing assembly 4 is in operation.

[0027] Please see Figure 3-8 The density of the arc-shaped blocks 71 at both ends and in the middle of the sealing cover 2 is greater than that of the arc-shaped blocks 71 at other locations. Therefore, when the spherical block 421 moves to either end or the middle of the sealing cover 2, the elastic sheet 41 rotates at a higher frequency. Conversely, when the spherical block 421 moves to other locations, the elastic sheet 41 rotates at a lower frequency. This ensures that livestock and poultry manure is more thoroughly mixed when the mixing assembly 4 is in operation.

[0028] Example 3

[0029] Based on Example 1, please refer to Figure 1-5 and Figure 10The elastic sheet 41 has sliders 43 at both ends, and slides 11 are provided on the inner sidewalls of both sides of the fermentation tank 1. The two sliders 43 are respectively located in the two slides 11. The bottom of the transmission component 42 is provided with a connecting ring 422, which is sleeved on the outer surface of the elastic sheet 41. When the first drive component 5 is working, the bearing component 3 and the stirring component 4 move together along the length of the fermentation tank 1. During this process, the transmission component 42 drives the elastic sheet 41 to move together through the connecting ring 422. The elastic sheet 41 drives the two sliders 43 to move together, and the sliders 43 slide along the slides 11. When the second drive component 6 is working, the bearing component 3 and the stirring component 4 move together along the width of the fermentation tank 1. During this process, the transmission component 42 drives the connecting ring 422 to slide along the outer surface of the elastic sheet 41. Because the elastic sheet 41 has a wavy structure, the connecting ring 422 can force the elastic sheet 41 to continuously change its shape, and the elastic sheet 41 can continuously stir livestock and poultry manure in the same vertical plane. If the first drive component 5 and the second drive component 6 work simultaneously, the elastic sheet 41 can move in three-dimensional space to more thoroughly mix livestock and poultry manure.
