Description

Technical Field

[0001] This invention belongs to the field of fertilizer manufacturing technology, and in particular relates to a fertilizer production equipment and process for aquatic processing waste. Background Technology

[0002] With the intensive development of the aquatic product processing industry, the treatment of aquaculture processing waste has become a key challenge for the industry. In order to improve the utilization rate of processing waste, the existing technology adopts the method of using processing waste to make fertilizer to complete the utilization function of waste.

[0003] When treating aquatic processing waste, steps such as mixing, fermentation, sterilization, and testing are required to prepare finished fertilizer. Existing technologies use earthworms for biological treatment during the fermentation process, utilizing earthworms to adsorb heavy metals and degrade organic matter. To improve the earthworms' burrowing and feeding efficiency, the material is loosened. However, existing technologies only loosen the material in the pre-treatment stage before adding earthworms. After the loosened material is left to stand, the sticky components, such as fish mucus, are prone to re-clumping, increasing the resistance to earthworm burrowing and reducing feeding efficiency. If the material is loosened after adding earthworms, it can easily cause mechanical damage to the earthworms, reducing their survival rate. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a fertilizer production equipment and process for aquatic processing waste, which can loosen the material by avoiding the addition of earthworms after adding earthworms to the fertilizer material, thereby ensuring the survival rate of earthworms and improving the degradation efficiency of heavy metals.

[0005] A fertilizer production device for aquatic processing waste includes a processing tank, a fixed ring connected to the processing tank, a sliding rod slidably connected to the fixed ring, a rotating rod rotatably connected to the sliding rod, a connecting plate fixed to the rotating rod, and multiple agitating rods rotatably connected to the connecting plate, each agitating rod being connected to an auxiliary rod.

[0006] It also includes a mating frame fixed to the slide rod, on which a transmission ring is slidably connected, and a torsion spring is provided at the rotatable connection between each agitator rod and the connecting plate.

[0007] The auxiliary rods are slidably connected to the agitator rods respectively.

[0008] It also includes an air intake rod fixed to the transmission ring, a blowing ring fixed to the air intake rod, multiple air outlets on the lower side of the blowing ring, an air intake hole on the air intake rod, and an air pump that can pump in oxygen connected to the blowing ring via a hose. Each air outlet is equipped with a one-way valve that allows gas to be blown out from the inside.

[0009] The beneficial effects of this equipment are as follows: during the fermentation and fertilizer production process, while ensuring the survival rate of earthworms, the earthworms are added to the fertilizer to be fermented, and then the fertilizer is loosened to improve the degradation efficiency of heavy metals, avoid direct contact with earthworms, and ensure their survival rate. At the same time, the tilt angle of multiple stirring rods can be changed, thereby changing the shape of the stirring body and providing different stirring effects for the materials.

[0020] A fertilizer production device from aquatic product processing waste includes a processing tank 501. A fixed ring 201 is connected to the processing tank 501, and a slide rod 101 is slidably connected to the fixed ring 201. The slide rod 101 has a rectangular protrusion, and the fixed ring 201 has a rectangular groove. The slide rod 101 is slidably connected to the fixed ring 201 through the cooperation of the rectangular protrusion and the rectangular groove. A first motor is fixedly connected to the fixed ring 201, and a first lead screw is fixedly connected to the output shaft of the first motor. A nut seat is fixedly connected to the slide rod 101, and the first lead screw drives the nut seat on the slide rod 101. A rotating rod 103 is rotatably connected to the slide rod 101. A through groove is provided inside the slide rod 101, and the rotating rod 103 is inserted into the through groove and connected to the nut seat via a bearing. The sliding rod 101 is rotatably connected to a rotating rod 103, which has two pins inserted into it. These pins contact the upper and lower ends of the sliding rod 101, respectively, restricting the rotation of the rotating rod 103 so that it can only rotate on the sliding rod 101 and cannot move up and down. A second motor is fixedly connected to the sliding rod 101, and a gear is fixedly connected to the output shaft of the second motor. A gear ring is fixedly connected to the rotating rod 103, and the meshing of the gear and gear ring drives the rotating rod 103 to rotate. A connecting plate 104 is fixedly connected to the rotating rod 103, and multiple agitator rods 105 are rotatably connected to the connecting plate 104. Each agitator rod 105 is connected to an auxiliary rod 106. The processing tank 501 is a tank that is closed on its periphery and bottom, with only the top open. Figure 1 To facilitate observation of the internal structure, a partial cross-section of the processing tank 501 is shown. When adding materials, the addition operation is carried out from the top of the processing tank 501. After the addition is completed, a lid is used to seal the top of the processing tank 501 to ensure that the materials will not fly out of the processing tank 501 during subsequent stirring.

[0021] The processing tank 501 contains aquatic waste material to be fermented after ethanol addition and pressure filtration. A compound bacteria composed of Bacillus subtilis and Bacillus licheniformis is added to the processing tank 501. Then, the rotating rod 103 is continuously rotated on the sliding rod 101, which in turn drives the connecting plate 104 to rotate continuously. This causes multiple stirring rods 105 and multiple auxiliary rods 106 connected to the connecting plate 104 to rotate synchronously with the connecting plate 104, thereby continuously stirring the material in the container and uniformly mixing the original material with the compound bacteria, providing a stable guarantee for subsequent fermentation operations. During the mixing process, the sliding rod 101 can be operated to slide on the fixed ring 201, thereby changing the stirring depth to facilitate comprehensive stirring of the material in the processing tank 501 and improve the mixing effect. Furthermore, during the stirring process, multiple stirring rods 105 can be rotated on the connecting plate 104, thereby changing the tilt angle of multiple stirring rods 105 and changing the shape of the stirring body, providing different stirring effects for the material and further improving the mixing effect.

[0022] After the addition and mixing of the compound bacteria are completed, hot air is circulated into the processing tank 501 using a circulating fan with its own heat source, or heat exchange pipes are added to the outside of the pipe body to regulate the temperature and humidity inside the processing tank 501. This provides a good fermentation environment for subsequent fermentation operations. Simultaneously, after temperature and humidity regulation, earthworms are added to the outer ring inside the processing tank 501. The biological characteristics of earthworms are used to degrade heavy metals in the material, improving subsequent use and accelerating decomposition. Before adding earthworms, the stirring rods 105 are pulled upwards from the material. Then, multiple stirring rods 105 are rotated on the connecting plate 104 to agitate the material. The rod 105 tilts downwards, and then the slide rod 101 slides down to insert multiple downward-tilting auxiliary rods 106 into the material. Since the multiple stirring rods 105 have already rotated, the multiple auxiliary rods 106 will not contact the outer ring area inside the processing tank 501 where earthworms were just added when they are inserted into the material. At this time, the rotating rod 103 continues to rotate and the slide rod 101 gradually moves down to stir the area where earthworms were not distributed after the earthworms were just added, thus loosening the area where earthworms had not burrowed in in advance. When the slide rod 101 slides down to a distance from the top surface of the material on the connecting plate 104, the multiple stirring rods 105 can be rotated upwards on the connecting plate 104. Figure 5 As shown in the figure, the connecting plate 104 is continuously rotated and the slide bar 101 is continuously moved down, thereby loosening the material in advance after the earthworms are added, thereby reducing the clumping of sticky components in aquatic waste such as fish viscera and crustacean waste, reducing the resistance of earthworms to drilling through the dispersed material, and promoting their uniform distribution and feeding efficiency.

[0023] Meanwhile, since this equipment performs the loosening operation only after the earthworms are added, compared to existing technologies that loosen the material before adding earthworms, this equipment can effectively reduce the time interval between the earthworms and the loosened material. This effectively avoids the material from coagulating again after loosening, which could affect the earthworms' burrowing. Furthermore, the rotatable design of multiple stirring rods 105 and the outer ring of earthworms ensure that the multiple stirring rods 105 and multiple auxiliary rods 106 will not come into contact with the newly added earthworms during the loosening process after the earthworms are added. This prevents any damage to the earthworms. Thus, while achieving the effect of loosening after the earthworms are added, it avoids damage to the earthworms during the loosening process, ensuring the earthworms' normal burrowing and feeding.

[0024] Earthworms are added only to the outer ring of the processing tank 501, avoiding the core stirring area, thus preventing mechanical damage to the earthworms. Multiple stirring rods 105 are raised and then tilted after the earthworms are added, which can avoid direct contact with the earthworms and ensure their survival rate. The auxiliary rod 106 moves down through the slide rod 101 to loosen the areas where earthworms are not distributed, reduce drilling resistance, and promote the even distribution of earthworms.

[0025] It also includes a mating frame 301 fixed to the slide rod 101. A transmission ring 302 is slidably connected to the mating frame 301. Two cylindrical rods are fixed to the transmission ring 302. The mating frame 301 is provided with two through holes. The sliding connection between the mating frame 301 and the transmission ring 302 is completed by the cooperation of the two cylindrical rods and the two through holes. A first electric push rod that can drive the transmission ring 302 to slide is fixed to the mating frame 301. A torsion spring is provided at the rotatable connection between each stirring rod 105 and the connecting plate 104.

[0026] Under normal conditions, multiple stirring rods 105 are pressed against the transmission ring 302 by the torsional force of the torsion spring. When it is necessary to rotate multiple stirring rods 105, the transmission ring 302 slides on the mating frame 301. The transmission ring 302 then provides downward pressure to multiple stirring rods 105, causing them to overcome the torsional force of the torsion spring and rotate on the connecting plate 104. This achieves the effect of changing the angle of the stirring rods 105, providing a driving force for improving the stirring effect and avoiding the position where earthworms have just been added.

[0027] The adjustable angle of the stirring rod 105 allows the material to be subjected to shearing force and tumbling action in different directions, avoiding the "dead angle" problem of traditional fixed-angle stirring and improving the uniformity of mixing.

[0028] Since the mating frame 301 is fixed to the slide rod 101, the mating frame 301 will not rotate with the rotating rod 103, so that the first electric push rod that drives the transmission ring 302 to slide will not rotate continuously, effectively avoiding wire entanglement. At the same time, the annular shape of the transmission ring 302 ensures that no matter what position the connecting plate 104 is in when the transmission ring 302 slides down, the transmission ring 302 can always press the multiple stirring rods 105 to rotate. That is, the annular structure of the transmission ring 302 is adapted to any rotation angle of the connecting plate 104, always maintaining uniform pressure on the stirring rods, ensuring the reliability of the adjustment action, and bringing convenience to subsequent drive operations.

[0029] Example 1: Aquatic waste processed using processing tank 501:

[0030] The aquatic waste includes fish viscera, fish organs, bones, scraps of meat, and fish skin, which are generated during the processing of aquatic products. The utilization of aquatic processing waste is achieved by processing the above-mentioned waste into fertilizer.

[0031] Example 2: Aquatic waste processed using processing tank 501:

[0032] The aquatic waste includes fish feces, uneaten feed, dead fish, and sludge from the bottom of fish ponds, which are generated during the aquaculture and processing process. The utilization of aquaculture and processing waste is achieved by processing the above-mentioned waste into fertilizer.

[0033] Multiple auxiliary rods 106 are slidably connected to multiple stirring rods 105. Each stirring rod 105 consists of a slender rod and a thick rod. A rectangular groove is provided inside each auxiliary rod 106. The multiple stirring rods 105 are slidably connected to the multiple auxiliary rods 106 by the slender rod engaging with the groove opening of the rectangular groove. Each stirring rod 105 is fixedly connected to a rectangular plate, and each rectangular plate is fixedly connected to a second electric push rod. Each auxiliary rod 106 is fixedly connected to a rectangular plate. The telescopic rods of the multiple second electric push rods are fixedly connected to the multiple rectangular plates. Each stirring rod 105 is fixedly connected to a battery, which powers the multiple second electric push rods to avoid tangled wiring. In actual use, to ensure comprehensive agitation of the material in the processing tank 501, the lengths of both the stirring rods 105 and the auxiliary rods 106 are greater than 20cm, while providing sufficient installation space for the second electric push rods and the batteries.

[0034] During the stirring process, multiple auxiliary rods 106 can be periodically slid on multiple stirring rods 105, and the multiple stirring rods 105 can rotate on the connecting plate 104 respectively. This allows the multiple stirring rods 105 and multiple auxiliary rods 106 to further agitate the material in different shapes, making it easier to mix the material evenly. By sliding the auxiliary rods 106 on the stirring rods 105 and adjusting the rotation angle of the stirring rods, the multiple stirring rods 105 and multiple auxiliary rods 106 can form a multi-form mixing action of spiral, shearing and impact during the rotation mixing process. This increases the material contact area, reduces sticky lumps, and makes the compound bacteria and materials evenly mixed.

[0035] Spiral: The rotating rod 103 drives the stirring rod 105 to rotate around the axis, and in conjunction with the upward sliding on the slide rod 101, the material can be stirred in a spiral-like trajectory, thereby driving some of the material to move, eliminating the stratification of the material, and forming a convection circulation after the material is stirred, improving the stirring effect, increasing the contact area between microorganisms such as Bacillus subtilis and aquatic waste, and the spiral shear force breaks down fish mucus and inhibits the formation of clumps. Furthermore, by changing the tilt angle of the stirring rod 105, the spiral rise angle is changed to further enrich the spiral stirring effect on the material.

[0036] Shearing: When the stirring rod 105 tilts and rotates with the rotating rod 103, its edge generates shear force on the material contact surface. The shear force further breaks down the fish mucus. At the same time, the shearing action can expand the diffusion channel of the bacterial solution and increase the permeability of the bacterial solution in the material. The heat energy generated by the shearing friction can stimulate the activity of microorganisms and shorten the fermentation start-up time. The relative displacement difference formed by the sliding of the auxiliary rod 106 and the stirring rod 105 can generate shear stress and improve the shearing effect. Furthermore, the depth of the shearing zone can be changed by sliding the slide rod 101 up and down to adapt to the processing needs of materials with different viscosities.

[0037] Impact: The sliding of the auxiliary rod 106 generates lateral displacement impact force to assist in the crushing of large fish bones and shell fragments. At the same time, the pores created by the impact can further improve the permeability of the bacterial solution in the material. The impact action is concentrated in the inner circle of the material, which can also avoid the outer circle earthworm activity area and reduce mechanical damage to earthworms. When the tilt angle is adjusted, the edge of the stirring rod 105 forms a high-frequency collision with the material, which further improves the impact effect. Combined with the oxygen purging of the air intake rod 304, the impact action enhances the looseness of the material and reduces the risk of blockage in the shear zone.

[0038] When loosening the earthworms after they are added, multiple auxiliary rods 106 can slide on multiple stirring rods 105 to adjust the stirring range of the multiple auxiliary rods 106, thereby further preventing the multiple auxiliary rods 106 and multiple stirring rods 105 from contacting the area where the earthworms are added during the loosening process, thus ensuring the survival of the earthworms.

[0039] It also includes an air intake rod 304 fixed to the transmission ring 302. A blowing ring 303 is fixed to the air intake rod 304. Multiple air outlets are opened on the lower side of the blowing ring 303. An air intake hole is opened on the air intake rod 304. Both the air intake rod 304 and the blowing ring 303 are hollow structures. The hollow structure of the air intake rod 304 is connected to the hollow structure of the blowing ring 303. The air intake hole on the air intake rod 304 is connected to an air pump that can pump in oxygen through a hose. Each air outlet is provided with an openable and closable rubber plug. When gas is blown out, the rubber plug will deform, allowing gas to be blown out through the rubber plug. When no gas is blown out, the rubber plug can automatically close to prevent external materials from entering the blowing ring 303. The above-mentioned rubber plug is very common in the prior art and has many applications, such as the impurity prevention structure in shower heads, so it will not be described in detail here.

[0040] During the agitation process, oxygen is injected into the air inlet rod 304 through a hose and blown out through multiple air outlets. This blows away the material at the sliding connection between the multiple agitator rods 105 and the multiple auxiliary rods 106, effectively preventing the material from clogging the sliding connection between the multiple agitator rods 105 and the multiple auxiliary rods 106 during equipment operation. This reduces the number of subsequent manual cleaning and maintenance operations and brings convenience to subsequent actual use.

[0041] Meanwhile, during the fermentation process, oxygen can be periodically blown out through multiple vents, and the slide bar 101 can be moved up and down repeatedly to periodically replenish oxygen into the fermenting material, thereby promoting oxygen penetration and preventing anaerobic putrefaction.

[0042] It also includes multiple shielding parts 401 that are slidably connected to the mating frame 301, multiple stirring rods 105 that are respectively located in the multiple shielding parts 401, each shielding part 401 has a through groove on both the front and rear sides, the multiple stirring rods 105 are respectively located in the rear through groove of the multiple shielding parts 401, and multiple auxiliary rods 106 are respectively located in the front through groove of the multiple shielding parts 401.

[0043] The multiple shielding parts 401 can guide the oxygen blown out from the blowing ring 303, thereby ensuring that the oxygen can be accurately blown to the sliding connection between the multiple stirring rods 105 and the multiple auxiliary rods 106, further improving the anti-blocking effect. At the same time, the multiple shielding parts 401 can also shield the sliding connection, further improving the anti-blocking effect.

[0044] Meanwhile, due to the arc-shaped arrangement of the multiple blocking parts 401, even when the multiple stirring rods 105 rotate on the connecting plate 104, the multiple blocking parts 401 can always block the sliding connection position between the multiple stirring rods 105 and the multiple auxiliary rods 106, further ensuring the continuous effect of avoiding blockage.

[0045] Because the multiple shielding parts 401 are rotatable, when the multiple stirring rods 105 rotate synchronously with the connecting plate 104, the multiple shielding parts 401 will rotate synchronously with the multiple stirring rods 105, thereby further ensuring a continuous and long-lasting shielding and guiding effect.

[0046] Each of the multiple shielding parts 401 is provided with a cleaning brush at the contact position with the blowing ring 303.

[0047] As multiple stirring rods 105 rotate synchronously with connecting plate 104, thereby driving multiple shielding parts 401 to rotate, the cleaning brushes on multiple shielding parts 401 will fully contact the lower area of ​​blowing ring 303, thereby fully brushing the lower area of ​​blowing ring 303, thus preventing material from sticking to the lower side of multiple air outlets.

[0048] It also includes a connecting rod 102 fixed to the fixed ring 201. A vertical rod is fixed to the fixed ring 201. The vertical rod and the connecting rod 102 are fixed to complete the connection between the fixed ring 201 and the connecting rod 102. A movable rod 601 is slidably connected to the connecting rod 102. Two scraping rods 602 are slidably connected to the movable rod 601. A compression spring is fixed between each scraping rod 602 and the movable rod 601.

[0049] After sliding the slide bar 101 upward to remove the material from the multiple stirring rods 105 and multiple auxiliary rods 106, the multiple auxiliary rods 106 can be operated to slide on the multiple stirring rods 105 respectively, thereby using multiple shielding parts 401 to scrape the material adhering to the multiple auxiliary rods 106, reducing material adhesion. At the same time, the slide bar 101 can be continuously slid upward until one of the multiple stirring rods 105 is inserted between two scraping rods 602. Then, the moving rod 601 is operated to slide on the connecting rod 102, thereby using the two scraping rods 602 to scrape the surface of the stirring rod 105, thereby scraping off the material adhering to the surface of the stirring rod 105, further achieving the effect of equipment self-cleaning maintenance.

[0050] Simultaneously, multiple agitator rods 105 can rotate on the connecting plate 104 during the cleaning process, allowing the two scraper rods 602 to scrape the agitator rods 105 at different angles, providing different angles of contact with the adhered materials, making it easier to scrape off the materials from different adhered areas and improving the cleaning effect.

[0051] It also includes a filter plate 502 fixed inside the processing tank 501. The filter plate 502 has multiple water outlet holes, and a layer of gauze is provided on the underside of the filter plate 502 to prevent solid materials from falling out.

[0052] After the aquatic waste material to be fermented is added into the processing tank 501, multiple plates that can be assembled into a complete circular plate can be connected to the lower side of the multiple auxiliary rods 106 by tightening bolts. Then, the sliding rod 101 continues to slide down, and the circular plate is used to squeeze the aquatic waste material to be fermented, so that the water is discharged from multiple outlets on the filter plate 502, further ensuring that the raw material has a low moisture content, which brings convenience to subsequent processing.

[0053] The processing tank 501 has a discharge port on its side wall to facilitate the discharge operation during subsequent processing. After processing is completed, the material is taken out from the discharge port. During processing, an arc-shaped baffle is used to block the discharge port to prevent material leakage.

[0054] It also includes an addition ring 202 fixed to the fixed ring 201. The addition ring 202 is provided with multiple partitions 203, which can divide the addition ring 202 into three parts.

[0055] When adding earthworms, earthworms are sprinkled into different areas separated by multiple partitions 203 on the adding ring 202, thereby ensuring that the earthworms are in the inner outer ring of the processing tank 501, which provides a guarantee for the subsequent stirring and loosening operation.

[0056] The aforementioned fertilizer production equipment made from aquatic processing waste includes a fertilizer preparation process comprising the following steps:

[0057] Step 1: Filter the aquatic processing waste using a pressure filter, then add a low concentration of ethanol;

[0058] Step 2: Mix the low-concentration ethanol evenly with the aquatic processing waste, and then remove it by pressure filtration again;

[0059] Step 3: Add straw powder and diatomaceous earth to the aquatic waste material after secondary pressure filtration to obtain aquatic waste material to be fermented;

[0060] Step 4: Add the aquatic waste material to be fermented into processing tank 501, and then add a compound bacteria composed of Bacillus subtilis and Bacillus licheniformis into processing tank 501;

[0061] Step 5: Operate the rotating rod 103 to rotate continuously on the slide rod 101, and make the slide rod 101 slide up and down on the fixed ring 201;

[0062] Step 6: Periodically allow the transmission ring 302 to slide on the mating frame 301;

[0063] Step 7: Slide the slide bar 101 upwards to separate the multiple stirring rods 105 from the material;

[0064] Step 8: Feed earthworms into the adding ring 202, and then slide the transmission ring 302 downward to make the multiple stirring rods 105 rotate downward;

[0065] Step 9: Slide the slide bar 101 downwards and keep rotating the rotating rod 103 rotating;

[0066] Step 10: Slide the transmission ring 302 upwards, and then continue to move the slide bar 101 downwards;

[0067] Step 11: Remove the materials for high-temperature sterilization and testing to complete the processing.
