Description

Technical Field

[0001] The invention relates to the technical field of liquid manure treatment, and in particular to intermittent aeration equipment for liquid manure fermentation treatment. Background Art

[0002] In today's environmental protection and agricultural fields, the effective treatment of liquid manure is crucial. Liquid manure fermentation treatment is a common and effective treatment method. The principle is to use anaerobic bacteria to hydrolyze, acidify and methanize the organic matter in the liquid, remove the organic matter in the urine, and reduce the harmfulness of the liquid.

[0003] In the process of liquid manure fermentation, aeration operation is indispensable. Aeration is a technology that transfers oxygen from the air to the liquid, which can provide the required oxygen for fungal reproduction and effectively improve the fermentation efficiency. However, there are many problems with the aeration devices currently on the market:

[0004] On the one hand, most aeration devices are fixed as a whole and cannot be flexibly adjusted according to actual working conditions. In addition, the aeration rods are prone to rust, which in turn affects the aeration volume. Too little aeration will significantly reduce the effect of liquid fermentation and cannot meet the needs of efficient treatment of liquid manure.

[0005] On the other hand, during the aeration process, the bubbles usually move straight upward, resulting in a relatively fixed working range of the bubbles. It is difficult to obtain a good aeration effect in some corners of the fermentation tank, resulting in insufficient fermentation of manure in these areas. In addition, the aeration holes are often clogged, which greatly affects the aeration quality and increases equipment maintenance costs and work difficulty.

[0006] In combination with the above content, it should be noted that: For example, the Chinese patent with patent application number 2024103215066 discloses an aeration device for liquid manure fermentation equipment, which adjusts the matching state between the rubber sleeve and the aeration pipe by changing the internal pressure of the aeration pipe to prevent liquid manure from entering the aeration pipe through the aeration hole or blocking the aeration hole;

[0007] However, during actual use, affected by the pressure of the centrally stored liquid manure and the aeration pipe's synchronous rotation and movement with the spiral blades, the combined pushing and squeezing pressure on the liquid manure causes the aeration pipe and the rubber sleeve to bear a large pressure during the air pressure coordination operation, resulting in high-intensity loads on the components and a significant reduction in component life. A solution is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 - Fig.11As shown, this embodiment is an intermittent aeration equipment for fermentation treatment of liquid feces, including a pressure-resistant top cover 1, a pressure-bearing seal 2 is arranged at the bottom of the pressure-resistant top cover 1, a traction liquid flow mechanism 5 is arranged on the inner wall of the pressure-bearing seal 2, a driving motor 101 is arranged at the top center of the pressure-resistant top cover 1, a spiral cone paddle 103 extending to the inside of the pressure-bearing seal 2 is arranged at the bottom of the driving motor 101, and a symmetrical guide aeration plate 201 is arranged on the inner wall of the pressure-bearing seal 2. The liquid feces are guided up to the liquid exchange pipe valve 4 into the fermentation aeration equipment, and are stored and fermented by the fermentation aeration equipment. The liquid feces are treated in advance, and microorganisms or agents can be added as needed.

[0037] A recessed groove is provided at the top center of the pressure-resistant top cover 1, and the driving motor 101 is embedded in the middle of the driving groove. A transmission shaft that passes through the recessed groove and is sleeved with the spiral cone propeller 103 is provided at the output end of the driving motor 101. The spiral cone propeller 103 is designed to be wide at the top and narrow at the bottom.

[0038] The bottom of the pressure-resistant top cover 1 is provided with multiple groups of inner filters 104 close to the inner walls on both sides of the recessed groove, and the end faces of the inner filters 104 are provided with arc-shaped filters on the inner top wall close to the end faces of the pressure-resistant top cover 1. The outer wall of the pressure-resistant top cover 1 is provided with multiple groups of exhaust pipe valves 102, and the exhaust pipe valves 102 are sleeved with the inner filters 104 and the arc-shaped filters.

[0039] A support bracket 202 located between multiple groups of guide aeration plates 201 is arranged at the bottom center of the pressure-bearing sealing cylinder 2, a sealing shaft 203 is arranged at the top center of the support bracket 202, the top of the guide aeration plate 201 is designed with an arc-shaped structure, an airway is arranged inside the guide aeration plate 201, and multiple groups of aeration microvalves are arranged on the surface of the guide aeration plate 201, and multiple groups of aeration microvalves are also arranged on the top pipe bodies of the aeration bottom pipe 304 and the aeration side pipe 305, and the aeration microvalves are one-way valves.

[0040] The driving motor 101 is started according to the timing set by the fermentation aeration equipment. The output end of the driving motor 101 is connected to the transmission shaft through a coupling, and drives the spiral cone paddle 103 to rotate inside the fermentation aeration equipment, so that the liquid feces and sewage located between the multiple groups of guide aeration plates 201 are pushed downward by the spiral cone paddle 103. Accordingly, the liquid feces and sewage between the guide aeration plates 201 are pulled to form a funnel-shaped flow trajectory, and the liquid feces and sewage located between the guide aeration plates 201 are continuously transported to the support cylinder seat 3, so that the liquid feces and sewage level between the guide aeration plates 201 is low. At the same time, when the liquid feces and sewage between the guide aeration plates 201 flows, the bubbles on the guide aeration plates 201 are pulled and mixed into the part of the liquid feces and sewage.

[0041] During the operation of the spiral cone paddle 103, the reciprocating cylinder 302 drives the diffuser net 303 to move back and forth laterally along the top of the aeration bottom pipe 304, so as to divide the liquid manure pushed by the spiral cone paddle 103, accelerate the bubbles to merge into the liquid manure, and push the bubbles overflowing from the aeration bottom pipe 304 and the aeration side pipe 305 to attach to the bottom wall of the support cylinder seat 3 in the reverse direction, and follow the liquid manure diversion to the multiple groups of traction liquid flow mechanisms 5. A plurality of convex columns are arranged on the bottom of the support cylinder seat 3 to divide the passing bubbles, such as Fig. 9 As shown, a mid-level active mode is formed, in which the liquid manure inside the fermentation aeration equipment is pushed down in a spiral for mixing treatment.

[0042] Example 2: Please refer to Figure 1 - Figure 5 As shown, this embodiment is an intermittent aeration equipment for liquid manure fermentation treatment, including a support cylinder seat 3 connected to a traction liquid flow mechanism 5 is arranged at the bottom of a pressure-bearing sealing cylinder 2, the traction liquid flow mechanism 5 includes a main shaft 501 and a slave shaft 504, and a traction belt 502 is sleeved on the surface of the main shaft 501 and the slave shaft 504. Liquid exchange pipe valves 4 are symmetrically arranged at both ends of the bottom of the support cylinder seat 3. During the fermentation treatment of liquid manure, according to the fermentation time and the requirements of the liquid manure fermentation process, an external air supply device is connected to the fermentation aeration equipment flange through a pipeline, and guides high-oxygen air to be transported to the guide aeration plate 201, the aeration bottom pipe 304 and the aeration side pipe 305, so as to supply oxygen to the liquid manure inside the fermentation aeration equipment to promote fermentation treatment.

[0043] Reciprocating cylinders 302 are symmetrically embedded on the inner walls on both sides of the support cylinder seat 3, and a diffuser net 303 located at the center of the support cylinder seat 3 is arranged between the reciprocating cylinders 302. Below the diffuser net 303, multiple groups of aeration bottom pipes 304 are embedded on the inner wall of the bottom of the support cylinder seat 3.

[0044] During the oxygen supply period, multiple groups of aeration bottom pipes 304 guide high-oxygen air to form a number of bubbles and fill the bottom of the diffuser net 303. The aeration side pipes 305 guide the high-oxygen air along the bottom side of the support cylinder seat 3 to form a number of bubbles that fill the diffuser net 303. The guide aeration plate 201 guides the high-oxygen air to continuously leak out on its surface to form a number of small bubbles. The bubbles filled in the fermentation aeration equipment float straight up without interference. Among them, the bubbles generated by the aeration bottom pipe 304 are affected by the diffuser net 303, blocked and separated by the diffuser net 303, and a number of sub-bubbles are generated.

[0045] The reciprocating cylinder 302 drives the air diffuser 303 to move back and forth horizontally above the aeration bottom plate, thereby continuously dividing and refining the bubbles generated by the aeration bottom pipe 304, thereby promoting the refined bubbles to merge into the liquid manure, forming a normal operation mode, and performing static aeration treatment on the liquid manure inside the fermentation aeration equipment.

[0046] A plurality of aeration side pipes 305 embedded in the side walls of the support cylinder seat 3 are arranged on both sides of the aeration bottom pipe 304, an outer support frame 301 is symmetrically arranged on the outer side wall of the bottom of the support cylinder seat 3, and the liquid exchange pipe valve 4 is symmetrically embedded in the bottom of both ends of the support cylinder seat 3, and a group of liquid exchange pipe valves 4 are also arranged on the top end surface of the pressure-resistant top cover 1.

[0047] Both sides of the main shaft member 501 and the slave shaft member 504 are provided with shaft sleeves that are embedded in the inner wall of the pressure-bearing sealing tube 2. Multiple groups of slave shaft members 504 are arranged in an up-down staggered manner and spliced ​​with the main shaft member 501 to form a triangular frame; multiple groups of scrapers 503 are provided on the surface of the traction belt 502, and the traction belt 502 is sleeved on the surface of the triangular frame to form a triangular transport track.

[0048] The traction liquid flow mechanism 5 is started at a fixed time, and the main shaft 501 and the slave shaft 504 are connected to the external servo motor through a coupling transmission, thereby driving the traction belt 502 to run on its surface. The inner wall of the traction belt 502 is provided with an anti-slip structure that cooperates with the surface of the main shaft 501 and the slave shaft 504. The traction belt 502 is replaced according to the liquid feces and is not limited to the graphic display. The traction belt 502 carries multiple sets of scrapers 503 and runs along the triangular transport track, thereby traction The liquid feces and sewage in the triangular structure area flows, thereby changing the storage state of the liquid feces and sewage in the areas on both sides of the fermentation and aeration equipment to prevent it from being continuously stationary.

[0049] At the same time, the bubbles generated by the traction part of the aeration bottom pipe 304 and the aeration side pipe 305 pass through this area, which enables the liquid manure and sewage at the inner edge of the fermentation aeration equipment to fully flow and contact with oxygen, thereby enhancing the fermentation treatment of the liquid manure and sewage, forming a primary active mode, and performing end-to-end symmetrical diversion and traction on the liquid manure and sewage inside the fermentation aeration equipment.

[0050] The traction liquid flow mechanism 5 is in continuous operation, pushing the spiral cone paddle 103 into the liquid manure diverted inside the support cylinder seat 3 for active traction, and under the guidance of the streamlined inner wall of the bottom inner wall of the support cylinder seat 3, the pressurized accumulated liquid manure is accelerated and guided to surge upward, forming a liquid manure flow trajectory with a central depression and sinking at both ends surging and tumbling inside the fermentation aeration equipment, and the liquid manure surging in the main shaft 501 area is thrown to the space between the traction belt 502 and the guide aeration plate 201 under the action of its own weight and the traction of the running trajectory of the traction belt 502. Under the influence of the downward push pressure of the spiral cone paddle 103, the liquid manure between the traction belt 502 and the guide aeration plate 201 cannot be effectively squeezed out and accumulated, so that the liquid manure overflowing the arc area at the top of the guide aeration plate 201 flows to the spiral cone paddle 103, so as to realize the diversion of the liquid manure after the surge, forming a high-load active mode.

[0051] The liquid manure inside the fermentation aeration equipment is treated by multiple linkage circulation trajectories of gas-liquid mixing, and the fermentation aeration equipment is operated in a multi-mode progressive manner according to the set program, specifically normal operation mode → primary active mode → intermediate active mode → high load active mode → normal operation mode. The progressive mode change is set at a certain interval according to the needs of liquid manure processing. Please refer to the attached Fig.10 and Fig.11 As shown, Fig.10 A represents the injection trajectory of liquid manure, B represents the flow trajectory of liquid manure in the fermentation aeration equipment, and C represents the aeration flow trajectory.

[0052] Combining Example 1 and Example 2, it can be seen that when the present invention treats liquid manure, the external air supply equipment conveys high-oxygen air to the guide aeration plate 201, the aeration bottom pipe 304 and the aeration side pipe 305, and aeration is carried out in multiple directions. The air diffusion net 303 cooperates with the reciprocating cylinder 302 to divide and refine the bubbles, thereby improving the fermentation efficiency.

[0053] The traction liquid flow mechanism 5 is started regularly to drive the scraper 503 to make the liquid manure flow, avoid stagnation and promote the fermentation process.

[0054] The driving motor 101 drives the spiral cone paddle 103, so that the liquid feces and sewage flows in a funnel shape and is mixed with air bubbles. The reciprocating cylinder 302 cuts the liquid feces and sewage to accelerate the integration of air bubbles.

[0055] The traction liquid flow mechanism 5 cooperates with the spiral cone paddle 103 to form a specific flow trajectory, realize the diversion of the upwelling liquid feces and sewage, and the equipment operates in multiple modes progressively to adapt to different fermentation stages and ensure efficient and stable fermentation.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
