Description

Technical Field

[0001] This invention relates to the field of anaerobic treatment technology, and more specifically, to an iron-based enhanced anaerobic fermentation device for pig manure and rice straw mixture. Background Technology

[0002] In the anaerobic treatment of biomass energy bio-fermentation, iron-based raw materials promote the hydrolysis of macromolecular organic matter into smaller molecules through reduction, accelerate their conversion to acetic acid, reduce acid inhibition, enrich hydrolytic acidifying bacteria and activate key enzyme activity. Iron ions can buffer the system pH, participate in enzyme synthesis, and improve the effect of anaerobic fermentation of pig manure and rice straw.

[0003] In publicly available literature, patent publication number CN111646664A discloses an anaerobic fermentation system. This technology utilizes the waste heat generated from methane combustion to heat water via a power generation and heat exchange device, which then heats the scum and sludge through heat exchange. An injection pipe connected to an external circulating pump is used to inject the heated sludge into the anaerobic fermentation tank. The injection port is located at the upper level of the tank, below the liquid surface, to achieve complete mixing. However, this technology still has the following problems.

[0004] In the later stages of anaerobic fermentation of iron-based raw materials, pig manure and rice straw are mixed, anaerobic bacteria need to be continuously added to the tank. However, anaerobic bacteria are sensitive to pH changes and are prone to deterioration and inactivation. In actual operation, there are cases where personnel violate regulations by directly adding unqualified bacteria, or even if the pH test is qualified, ineffective bacteria are mistakenly added due to misoperation. This loss of control caused by human negligence disrupts the activity and metabolic balance of microorganisms, resulting in a significant decrease in the anaerobic treatment effect.

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention, through the cooperation of the cover pressure component, the positioning verification component, and the blocking unit, automatically seals the top of the tank when anaerobic bacteria agent is added to the receiving hopper inside the tank. The blocking strip releases the obstruction of the pH sensor, driving the pH sensor to move and insert into the guide plate to perform in-situ pH verification of the bacteria agent. This forms a complete closed-loop process from top sealing, automatic internal positioning to in-situ verification, realizing mandatory automated verification before the addition of anaerobic bacteria agent. It eliminates the operational space for personnel to illegally add unqualified anaerobic bacteria agent directly, avoids loss of control due to human negligence, and significantly improves the anaerobic treatment effect.

[0017] 2. This invention uses a positioning verification component. By using a T-shaped block and a semi-circular block in conjunction with the inclined groove in the guide plate, mechanical guidance and dimensional verification are achieved when the pH sensor is inserted. This ensures that the sensor accurately enters the container to contact the bacterial agent. The blocking unit uses the linkage between the counterweight and the connecting rope to make the blocking bar act before the pH sensor. After the blocking is released in an orderly manner, the sensor is allowed to pass through the through hole to perform the test, ensuring the timing accuracy of the verification process.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1: like Figure 1 - Figure 4The iron-based raw material-enhanced anaerobic fermentation device for pig manure and rice straw includes a fermentation tank 1, with a trough 2 fixedly connected to the upper surface of the fermentation tank 1; the device also includes: a moving block 3, disposed on one side of the trough 2; a cover pressing component, installed at one end of the moving block 3, used to cover and seal the top surface of the trough 2 when anaerobic bacteria are added into the trough 2; a positioning verification component, installed on one side of the moving block 3 and close to one end of it, with a pH sensor 4 installed on the positioning verification component; a blocking unit, installed on one side of the moving block 3 and away from one end of it, with a baffle 6 installed on the blocking unit; and a guide plate 5 installed inside the trough 2.

[0030] In this embodiment, when anaerobic bacteria agent needs to be added, it is added into the receiving hopper 17 inside the tank 2. When the capping component seals the top surface of the tank 2, it drives the moving block 3 to rotate. The rotation of the moving block 3 activates the blocking unit, causing the baffle 6 to tilt downwards and release the obstruction of the pH sensor 4. Simultaneously, the rotation of the moving block 3 also drives the positioning verification component, causing the pH sensor 4 to move and insert into the guide plate 5 to detect the pH of the added anaerobic bacteria agent. The anaerobic bacteria agent can only be tested after the top is sealed and the internal automatic positioning verification is completed during addition. This prevents operators from interfering with the normal addition of the anaerobic bacteria agent and ensures that unqualified agents are not added into the fermenter 1. This avoids uncontrolled addition due to human negligence and significantly improves the anaerobic treatment effect. Example 2: like Figure 2 As shown, in this embodiment, the covering component includes: a cover plate 7, fixedly connected to one end of the moving block 3, the cover plate 7 being slidably connected to the tank 2, and a rotating rod 8 fixedly installed on the inner wall of the cover plate 7; a reduction motor 9, installed at the bottom end of the rotating rod 8, the reduction motor 9 being used to drive the rotating rod 8 to rotate, and the lower surface of the reduction motor 9 being fixedly connected to the fermentation tank 1. The upper surface of the cover plate 7 is parallel to the upper surface of the tank 2.

[0031] In this embodiment, the controller 27 starts the reduction motor 9, which drives the rotating rod 8 to rotate counterclockwise. The rotating rod 8 drives the cover plate 7 to rotate counterclockwise, and the cover plate 7 drives the moving block 3 to rotate counterclockwise. In this way, the cover plate 7 covers and seals the top surface of the tank 2, ensuring that the pH value is detected under the sealed environment inside the tank 2 when the anaerobic bacteria agent is added.

[0032] Example 3: like Figure 2 - Figure 5As shown, in this embodiment, the positioning verification component includes: a movable rope 10, fixed to one side of the movable block 3 and near one end thereof, with a sliding block 11 fixed to the bottom end of the movable rope 10, and the sliding block 11 being fixedly connected to the PH sensor 4, and the movable rope 10 being slidably connected to the groove cylinder 2; a guide post 12, installed on the inner wall of the sliding block 11, used to guide the sliding block 11 to slide, a sliding frame 13 installed on the outer wall of the sliding block 11, the sliding frame 13 being slidably connected to the sliding block 11, and the sliding frame 13 being fixedly connected to the groove cylinder 2; a T-shaped block 14, fixed to the top of the outer wall of the PH sensor 4, with a semi-circular block 15 fixedly installed on one side of the outer wall of the PH sensor 4, the bottom center point of the PH sensor 4 being higher than the upper surface of the stop bar 6; and an inclined groove 16, formed on the inner wall of the guide plate 5. Both the T-shaped block 14 and the semi-circular block 15 are inclined, and the upper surface of the T-shaped block 14 is higher than the upper surface of the inclined groove 16. The inclined slot 16 is set at an angle, and the inclined slot 16 is used for the insertion operation of the T-shaped block 14 and the semi-circular block 15.

[0033] In this embodiment, when the stop bar 6 releases its obstruction of the pH sensor 4, the counterclockwise rotation of the moving block 3 will cause the top end of the moving rope 10 to rotate counterclockwise and release. Under the influence of gravity, the sliding block 11 will guide the pH sensor 4 to move downwards along the outer wall of the guide post 12 and the inner wall of the sliding frame 13. The sliding block 11 then guides the pH sensor 4 to move downwards, which in turn guides the T-shaped block 14 and the semicircular block 15 to move downwards. Thus, the T-shaped block 14, the semicircular block 15, and the pH sensor 4 all pass through the through hole 23. Until the pH sensor 4 moves and is inserted into the guide plate 5, the semicircular block 15 and the inclined groove 16 can pass through the inclined groove 16 inside the guide plate 5 according to the specified dimensions, ensuring that the pH sensor 4 is guided and verified into the interior of the container 17. The pH sensor 4 contacts the anaerobic agent. When the pH value detected by the pH sensor 4 is the same as the pH value set by the controller 27, it is qualified. When the pH value detected by the pH sensor 4 is different from the pH value set by the controller 27, it is displayed on the display screen on the controller 27 and the management personnel are alerted. This avoids the pH sensor 4 being verified externally and the addition of unqualified anaerobic agent.

[0034] Example 4: like Figure 2 - Figure 8As shown, in this embodiment, the blocking unit includes: a connecting rope 18, fixed to one side of the moving block 3 and away from one end thereof; a grooved sleeve 19 is fixedly installed at the bottom end of the connecting rope 18; the grooved sleeve 19 is fixedly connected to the stop bar 6; and the connecting rope 18 is slidably connected to the grooved cylinder 2; a protruding rod 20 is installed on the inner wall of the grooved sleeve 19; the protruding rod 20 is used to guide the grooved sleeve 19 to slide; and the protruding rod 20 is fixedly connected to the grooved cylinder 2; a counterweight 21 is fixedly installed at the bottom end of the stop bar 6; the counterweight 21 is used to counterweight the stop bar 6; an inclined support plate 22 is connected to one side of the stop bar 6; both the stop bar 6 and the counterweight 21 are slidably connected to the inclined support plate 22; and the inclined support plate 22 is fixedly connected to the grooved cylinder 2; and a through hole 23 is formed inside the inclined support plate 22 and located on one side of the stop bar 6. The vertical cross-sectional area of ​​the stop bar 6 is larger than the vertical cross-sectional area of ​​the through hole 23, and the through hole 23 is inclined.

[0035] In this embodiment, the pH sensor 4 is initially located at the right-side sealing position of the inclined support plate 22, while the baffle 6 blocks the through hole 23. This prevents external personnel from directly contacting the pH sensor 4 to verify the pH value. Only when the moving block 3 rotates counterclockwise will it cause the top of the connecting rope 18 to rotate counterclockwise, thereby releasing the connecting rope 18. Under the counterweight force of the counterweight block 21 and the baffle 6, the counterweight block 21 causes the baffle 6 to tilt downwards. 6. The baffle 6 tilts and moves downward, causing the groove sleeve 19 to tilt and move downward. The groove sleeve 19 is guided to tilt and move downward along the outer wall of the protruding rod 20. The height of the upper surface of the right-moving baffle 6 is less than the height of the lower surface of the pH sensor 4. Therefore, the baffle 6 tilts and moves downward before the pH sensor 4. In this way, the baffle 6 opens the through hole 23 on the inclined support plate 22, allowing the baffle 6 to tilt and move downward, thus removing the obstruction to the pH sensor 4 and facilitating the pH sensor 4 to pass through the through hole 23 to perform the pH value detection operation of the anaerobic agent.

[0036] Example 5: like Figure 1 - Figure 8 As shown, in this embodiment, a container 17 is fixed on the lower surface of the guide plate 5, and the container 17 is rotatably connected to the trough 2; a servo motor 24 is installed at one end of the container 17, and the servo motor 24 is fixedly connected to the trough 2. The output end of the servo motor 24 is rotatably connected to the trough 2. The servo motor 24 is used to drive the container 17 to rotate; an exhaust pipe 25 connected to the fermentation tank 1 is installed on one side of the servo motor 24; a cover 26 is provided on one side of the exhaust pipe 25, and the cover 26 is threadedly connected to the fermentation tank 1. A controller 27 is provided on one side of the cover 26, and the controller 27 is fixedly connected to the fermentation tank 1. The controller 27 is electrically connected to the servo motor 24.

[0037] In this embodiment, during initial use, the exhaust pipe 25 is connected to the main exhaust pipe. By reversing the cover 26, the cover 26 is separated from the fermentation tank 1 by threads. After separation, the iron-based raw material fortified pig manure and rice straw mixture is added into the fermentation tank 1. Then, the cover 26 is sealed and anaerobic fermentation is carried out. At the same time, when it is necessary to add anaerobic bacteria, it can be added to the receiving hopper 17 inside the tank 2 first.

[0038] When the pH value detected by pH sensor 4 is the same as the pH value set by controller 27, it is considered qualified. This requires the geared motor 9 to drive the rotating rod 8 to rotate clockwise. The rotating rod 8 drives the cover plate 7 to rotate clockwise, and the cover plate 7 no longer presses against the top of the tank cylinder 2. Simultaneously, the cover plate 7 drives the moving block 3 to rotate clockwise. The moving block 3 pulls the moving rope 10, which in turn causes the sliding sleeve block 11 to tilt upwards. The sliding sleeve block 11 then causes the pH sensor 4 to tilt upwards. After separating from the inside of the guide plate 5, the pH sensor 4 moves to the area above the stop bar 6. At the same time, the moving block... 3. Pull the connecting rope 18 clockwise. The connecting rope 18 drives the groove sleeve 19 to move upward. The groove sleeve 19 drives the baffle 6 to tilt upward. The baffle 6 tilts upward along the outer wall of the protruding rod 20. Immediately, the servo motor 24 is activated through the controller 27. The servo motor 24 drives the container 17 to rotate counterclockwise. The container 17 rotates counterclockwise inside the groove cylinder 2, so that the qualified anaerobic bacteria agent inside the container 17 can be added into the fermenter 1 for anaerobic fermentation treatment. The outer wall of the container 17 is a layer of flexible silicone material, which can maintain a sealed state at the contact part with the groove cylinder 2.

[0039] like Figure 9 As shown, in this embodiment, a valve 28 is installed at the bottom of the fermentation tank 1, and the valve 28 is connected to the fermentation tank 1. After the anaerobic fermentation is completed, the valve 28 can be opened to discharge the material inside the fermentation tank 1, which facilitates subsequent material discharge and cleaning operations.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
