Description

[0001] The present invention relates to the technical field of manure fermentation, and specifically to a heating and oxygen-increasing device suitable for aerobic fermentation of solid manure. Background Art

[0002] With the rapid development of large-scale breeding and organic agriculture, the resource utilization of solid manure has become an important topic for the sustainable development of agriculture. As one of the core technologies for the harmless treatment of manure and the production of organic fertilizers, aerobic fermentation directly affects the product quality and environmental benefits in terms of efficiency and stability. However, there is still room for optimization in aspects such as the uniformity of oxygen supply, fermentation temperature control, and energy consumption optimization. For details, reference can be made to the solid manure tank-type aerobic fermentation equipment disclosed in the patent number CN219730810U;

[0003] The above-mentioned patent content increases the contact area by laying manure in layers, but the layered structure will increase the resistance to oxygen transfer between the material layers, and the penetration depth of deep-layer oxygen is low, making it difficult to meet the fermentation requirements of high-moisture-content manure;

[0004] At the same time, the composting process also relies on natural turning or single-bottom aeration, resulting in deep-layer oxygen deficiency and incomplete fermentation in the material pile, further affecting the fermentation efficiency of manure. Therefore, a solution is proposed herein. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of insufficient oxygen supply and incomplete fermentation in traditional manure fermentation methods.

A concave lifting frame is jointly hinged between the two lifting rods, and the concave lifting frame is sleeved outside the double-tooth slide plate. A cylinder I is jointly arranged between the inner wall of the top of the concave lifting frame and the top surface of the double-tooth slide plate.

[0010] Furthermore, concave positioning frames are respectively movably sleeved at the front and rear ends of the limiting frame. A pressing frame with a concave structure is jointly fixedly connected between the two front and rear concave positioning frames and on one side. A sliding rod is installed through the center of the concave positioning frame;

[0011] One end of the sliding rod is slidably connected inside a chute arranged on the outer wall of the limiting frame, and a damping spring shock-absorbing ring I is jointly fixedly connected between the end of the sliding rod and the inner wall of the bottom of the chute. The other end of the sliding rod extends into the corrugated groove. The bottom of the pressing frame is fixedly installed with distributing rods at the front, rear and center positions.

[0012] Furthermore, vertical rods are rotatably connected at the front and rear ends of the spiral rotating rod inside the limiting frame. A limiting tooth roller is arranged at the top of the vertical rod and meshes with the tooth blocks on the side wall of the double-tooth slide plate. A material-breaking roller is fixedly installed at the bottom end of the vertical rod. An intermittent oxygen supply assembly is arranged on one side of the limiting frame away from the pressing frame.

[0013] Furthermore, the intermittent oxygen supply assembly includes two oxygen supply cylinders. The two oxygen supply cylinders are respectively movably arranged at the front and rear positions on one side of the limiting frame away from the pressing frame. A collar is fixedly installed near the middle section of the outside of the oxygen supply cylinder. A connecting rod is jointly fixedly installed between the two collars and at the bottom end of the spiral rotating rod. An oxygen supply machine is arranged at the center of the bottom of the connecting rod. A T-shaped oxygen supply pipe is arranged at the center of the bottom of the oxygen supply machine.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention is provided with a double-tooth sliding plate and an auxiliary fermentation mechanism. By using the pressing frame to intermittently apply pressure to the initial high-moisture-content manure and forcing the sewage to be separated, it ensures that the moisture content in the initial stage of fermentation is within the suitable range for microbial metabolism, which is beneficial to manure fermentation. At the same time, the material-breaking roller rotates by itself through the engagement of the limiting tooth roller and the double-tooth sliding plate. It not only breaks the large-volume organic matter into small particle sizes but also facilitates the turning and ventilation of the material pile, forcing the oxygen penetration depth to increase, and further improving the manure fermentation efficiency.

[0019] 2. The present invention sets an intermittent oxygen supply component in cooperation with the auxiliary fermentation mechanism. The oxygen supply cylinder moves up and down along the corrugated groove through the first sliding shaft. Combining the multi-layer oxygen supply path of the T-shaped oxygen supply pipe, the oxygen utilization rate is improved, forcing deep oxygen supply to the material pile. At the same time, the second cylinder drives the spiral rotating cylinder to scrape and clean the mouth of the oxygen supply cylinder in a spiral manner, preventing manure blockage and reducing the risk of oxygen supply interruption, effectively improving the manure oxygen supply efficiency.

Detailed implementation manners

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Please refer to Figures 1-6 As shown, a heating and oxygen-increasing device applicable to aerobic fermentation of solid manure includes a fermentation frame 1. On both sides of the center inside the fermentation frame 1, concave stacking frames 2 are symmetrically hinged, and the bottom of the stacking frame 2 is a mesh structure. On both sides of the front end frame of the fermentation frame 1, guide frames are respectively obliquely penetrated.

[0032] Corrugated grooves are provided on the front and rear inner walls of the fermentation frame 1. At the top inside the fermentation frame 1, a double-tooth slide plate 3 with a side cross-section in an inverted convex shape is provided, and an auxiliary fermentation mechanism 4 is provided at the bottom end of the double-tooth slide plate 3.

[0033] Among them, the auxiliary fermentation mechanism 4 includes a double-shaft motor 41. The double-shaft motor 41 is fixedly installed at the center of the top end of the double-tooth slide plate 3 through a machine base, and spiral rotating rods 42 with reverse threads are respectively fixedly installed at both ends of its output shaft. Guide rods 43 are fixedly installed at the front and rear ends of the spiral rotating rods 42 inside the fermentation frame 1. Limit frames 44 are slidably sleeved outside the two groups of guide rods 43 at both ends of the double-shaft motor 41, and the two groups of limit frames 44 are respectively spirally sleeved outside the two groups of spiral rotating rods 42.

[0034] Concave positioning frames 45 are movably sleeved at the front and rear ends of the limit frame 44. A concave pressing frame 46 is fixedly connected between the front and rear two groups of concave positioning frames 45 on one side. A slide rod 47 is penetrated through the center of the concave positioning frame 45.

[0035] One end of the slide rod 47 is slidably connected to the inside of the slide groove provided on the outer wall of the limit frame 44, and a damping spring shock absorbing ring 48 is fixedly connected between the end of the slide rod 47 and the inner wall of the bottom of the slide groove, and the other end of the slide rod 47 extends to the inside of the corrugated groove;

[0036] The bottom of the pressing frame 46 is fixedly installed with a material dividing rod 49 at the front and rear ends and the center. The inside of the limit frame 44 is located at the front and rear ends of the spiral rotating rod 42 and is vertically rotatably connected with a vertical rod 410. The top of the vertical rod 410 is provided with a limit tooth roller 411 and meshes with the side wall tooth block of the double-toothed slide plate 3, and the bottom of the vertical rod 410 is fixedly installed with a material breaking roller 412.

[0037] The two sets of guide frames are used to transport the fixed amount of solid manure to the corresponding concave stacking frames 2, and then the double-axis motor 41 is started to drive the two sets of spiral rods 42 to rotate. Since the external threads of the two sets of spiral rods 42 are arranged in opposite directions, when the two sets of spiral rods 42 rotate in the same direction, the corresponding limit frames 44 are respectively driven to slide to both sides along the outside of the guide rod 43, and the limit frames 44 drive the pressing frame 46 and the two sets of vertical rods 410 to move synchronously.

[0038] The material pressing frame 46 is then used to move along the surface of the material pile to assist in flattening the surface of the material pile. At the same time, the multi-component material rod 49 moves accordingly and divides the flattened material pile to enhance air permeability. As the sliding rod 47 moves along with the material pressing frame 46, the end of the sliding rod 47 moves along the inside of the corrugated groove, realizing the up and down movement of the sliding rod 47, the concave positioning frame 45 and the material pressing frame 46. When the material pressing frame 46 sinks downward, the sliding rod 47 presses against the damping spring shock absorbing ring 48 for compression, and the material pressing frame 46 presses downward against the manure material pile, forcing the manure with a high water content initially to precipitate water, so as to prevent the water content in the manure from far exceeding the metabolic requirements of microorganisms and affecting the manure fermentation effect;

[0039] At the same time, when the vertical pole 410 moves with the limiting frame 44, the material breaking roller 412 at the bottom end of the vertical pole 410 is inserted into the manure pile. The limiting tooth roller 411 is meshed with the three tooth blocks of the double-toothed slide plate to realize the self-rotation of the vertical pole 410 and the material breaking roller 412. The self-rotation crushing and stirring action of the material breaking roller 412 crushes the larger volume of organic matter inside the material pile into small particles, forcing the oxygen penetration to be improved, and realizing the turning and ventilation of the material at the same time, thereby accelerating the fermentation speed of the manure material;

[0040] It is worth noting that the end positions of the front and rear ends of the two groups of stacking frames 2 are fixedly installed with round shafts 201, and the two adjacent groups of round shafts 201 are commonly sleeved with lifting rods 202, and the two groups of lifting rods 202 are commonly hinged with a concave lifting frame 203, and the concave lifting frame 203 is sleeved on the outside of the double-toothed slide plate 3, and a cylinder 204 is commonly arranged between the top inner wall of the concave lifting frame 203 and the top surface of the double-toothed slide plate 3;

[0041] After fermentation is completed, cylinder 1 (204) is activated to drive the concave lifting frame (203) to rise along the track of the double-toothed slide plate (3). When the concave lifting frame (203) rises, the lifting rods (202) are used to respectively pull the corresponding round shafts (201) to rise. The stacking frame (2) rotates with the central hinge as the center, forcing the solid manure to fall into the fermentation frame (1) through the material guiding frame and be discharged outward. When the concave lifting frame (203) is reset, the stacking frame (2) is driven to reset by the lifting rods (202).

[0042] Embodiment 2: Please refer to Figure 1 、 Figure 4 、 Figure 7 - Figure 8 As shown in, an intermittent oxygen supply assembly (5) is provided on the side of the limit frame (44) away from the pressure frame (46). The intermittent oxygen supply assembly (5) includes two oxygen supply cylinders (51). The two oxygen supply cylinders (51) are respectively movably arranged at the front and rear of the side of the limit frame (44) away from the pressure frame (46). A collar (52) is fixedly installed near the middle section of the outside of the oxygen supply cylinder (51). A connecting rod is fixedly installed between the two collars (52) and at the bottom end of the spiral rod (42). The center of the bottom of the connecting rod is provided with an oxygen supply machine (53). The center of the bottom of the oxygen supply machine (53) is provided with a T-shaped oxygen supply pipe, and the front and rear ends of the oxygen supply pipe are respectively fixedly connected to the opposite sides of the oxygen supply cylinder (51);

[0043] One end of each of the two collars (52) away from each other is fixedly installed with a first sliding shaft (54), and the first sliding shaft (54) is slidably connected inside the corresponding corrugated groove. A second sliding shaft (55) is fixedly installed at the top of the oxygen supply cylinder (51) near the limit frame (44), and one end of the second sliding shaft (55) is slidably connected inside the vertical groove provided on one side of the limit frame (44). A damping spring shock absorber (56) is fixedly connected between the bottom end of the second sliding shaft (55) and the inner wall of the bottom of the vertical groove;

[0044] During the material breaking and turning process, the intermittent oxygen supply assembly (5) will move synchronously with the limit frame (44). The bottom openings of the two oxygen supply cylinders (51) are respectively aligned with the corresponding positions of the manure pile. Since the oxygen supply cylinder (51) pulls the first sliding shaft (54) and the second sliding shaft (55) to move synchronously, the end of the first sliding shaft (54) slides inside the corresponding corrugated groove and is pressed by its curved surface, realizing the up and down undulating movement of the first sliding shaft (54), the collar (52), the second sliding shaft (55), the oxygen supply cylinder (51) and its connecting components. At the same time, the second sliding shaft (55) moves inside the vertical groove, and the damping spring shock absorber (56) is continuously reset and compressed to assist the up and down reciprocating movement of the oxygen supply cylinder (51);

[0045] When the two groups of oxygen supply cylinders 51 move downward, they are respectively inserted into the manure and sewage pile, and are located at the dividing line of the front and rear material dividing rods 49. Subsequently, the oxygen supply machine 53 is started, and oxygen is supplied into the two groups of oxygen supply cylinders 51 through the T-shaped oxygen supply pipe, and the oxygen is sent into the manure and sewage pile through the bottom nozzle of the oxygen supply cylinder 51. In an aerobic environment, the microorganisms in the manure and sewage pile can carry out aerobic fermentation on the manure and sewage. Since the oxygen supply range will also change when the oxygen supply cylinder 51 moves upward, multi-layer oxygen supply to the pile can be realized. Through this reciprocating motion, aerobic fermentation of the manure and sewage pile can be continuously carried out.

[0046] It should be noted that during the intermittent oxygen supply process, the nozzle of the oxygen supply cylinder 51 is prone to infiltrate and introduce an appropriate amount of solid manure and sewage, resulting in the blockage of the oxygen supply port. Therefore, a spiral rotating cylinder 57 with a T-shaped structure is spirally penetrated and connected inside the oxygen supply cylinder 51 at the top end, and a spiral groove adapted to the outer wall of the spiral rotating cylinder 57 is arranged on the inner wall of the top of the oxygen supply cylinder 51. The bottom cylinder body of the spiral rotating cylinder 57 is adapted to the inside of the oxygen supply cylinder 51, and the outer wall is set as a rough surface. The top end of the spiral rotating cylinder 57 extends outside the oxygen supply cylinder 51 and is fixedly sleeved with a double-axis snap ring 58.

[0047] An H-shaped snap frame 59 is jointly sleeved between the front and rear two groups of double-axis snap rings 58. The front and rear end frames of the H-shaped snap frame 59 are respectively sleeved at the middle sections of the two groups of double-axis snap rings 58, and a cylinder two 510 is jointly arranged between the center of the bottom of the H-shaped snap frame 59 and the connecting rod near one side.

[0048] During the up and down movement of the oxygen supply cylinder 51, when the bottom nozzle of the oxygen supply cylinder 51 is completely separated from the manure and sewage, the cylinder two 510 is started, and it is used to push the H-shaped snap frame 59 to move up and down. The H-shaped snap frame 59 drives the spiral rotating cylinder 57 to perform spiral lifting and lowering inside the oxygen supply cylinder 51 through the double-axis snap ring 58.

[0049] Since the bottom cylinder body of the spiral rotating cylinder 57 is adapted to the inside of the oxygen supply cylinder 51, and the spiral rotating cylinder 57 rotates in cooperation with the spiral groove at the nozzle of the oxygen supply cylinder 51 during lifting and lowering, the rough surface of the bottom cylinder body of the spiral rotating cylinder 57 is forced to scrape and clean the bottom air outlet nozzle of the oxygen supply cylinder 51, effectively avoiding the blockage of the exhaust port of the oxygen supply cylinder 51 and ensuring the smoothness of oxygen supply.

[0050] Working principle:

[0051] First of all, the solid manure and sewage to be fermented are respectively sent into the corresponding concave-shaped material stacking frames 2 through the two groups of material guiding frames. Subsequently, the double-axis motor 41 is started to drive the two groups of spiral rods 42 to rotate in the same direction. Since the external threads of the spiral rods 42 are arranged in the opposite direction, when rotating, the two groups of limit frames 44 will be driven to move to both sides along the guide rods 43, and at the same time, the pressing frame 46 and the vertical rod 410 will be driven to move synchronously.

[0052] During the movement of the pressure frame 46, the manure pile is divided by the material dividing rod 49 to enhance air permeability. At the same time, the sliding rod 47 moves with the pressure frame 46 and undulates up and down in the corrugated groove to intermittently apply pressure to the manure, forcing the water in the high moisture content manure to separate out, so as to ensure that the moisture content in the initial stage of fermentation is within the suitable range for microbial metabolism;

[0053] As the limit frame 44 moves, the material breaking roller 412 at the bottom of the vertical rod 410 is inserted into the manure pile. Since the limit tooth roller 411 meshes with the tooth blocks of the double-tooth sliding plate 3, the vertical rod 410 and the material breaking roller 412 rotate self - identically to break and stir the manure, crush the large - volume organic matter into small particle sizes, improve the oxygen penetration degree, and realize the turning and ventilation of the material, accelerating the fermentation speed of the manure material;

[0054] During the material breaking and turning process, the intermittent oxygen supply assembly 5 moves synchronously with the limit frame 44. The bottom barrel opening of the oxygen supply cylinder 51 is aligned with the corresponding position of the manure pile. As the oxygen supply cylinder 51 undulates up and down, the oxygen supply machine 53 supplies oxygen to the inside of the oxygen supply cylinder 51 through the T - shaped oxygen supply pipe, and the oxygen is sent into the inside of the manure pile through the bottom barrel opening of the oxygen supply cylinder 51 to realize the aerobic fermentation of the manure. Due to the up - and - down movement of the oxygen supply cylinder 51, the oxygen supply range changes, realizing multi - layer oxygen supply to the material pile and improving the oxygen utilization rate;

[0055] When the bottom barrel opening of the oxygen supply cylinder 51 is completely separated from the manure, the cylinder two 510 is started to push the H - shaped clamping frame 59 up and down, and drives the spiral rotating cylinder 57 to perform spiral lifting inside the oxygen supply cylinder 51 through the double - shaft clamping ring 58. The rough surface of the bottom cylinder body of the spiral rotating cylinder 57 scrapes and cleans the bottom air outlet cylinder opening of the oxygen supply cylinder 51 to prevent the manure from blocking the exhaust port of the oxygen supply cylinder 51 and ensure the smoothness of oxygen supply;

[0056] After the fermentation is completed, the cylinder one 204 is started to drive the concave lifting frame 203 to rise along the track of the double - tooth sliding plate 3. When the concave lifting frame 203 rises, the lifting rods 202 respectively pull the corresponding round shafts 201 to rise, and the stacking frame 2 rotates with the central hinge as the center, forcing the solid manure to fall into the fermentation frame 1 through the guide frame and be discharged outward. When the concave lifting frame 203 resets, the stacking frame 2 is driven to reset by the lifting rods 202.

[0057] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation manners. Obviously, many modifications and changes can be made according to the content of this specification.
