[0002] With the development of the intensive aquaculture industry, the processing of aquaculture waste has become a key challenge in the industry. In order to improve the utilization rate of processing waste, the prior art uses processing waste to make fertilizer to complete the utilization function of the waste. When processing the water product processing waste, the waste needs to be prepared into finished fertilizer through steps such as mixing, fermentation, sterilization and detection. In the fermentation process, the prior art uses earthworms to biologically treat the fertilizer, and uses earthworms to adsorb heavy metals and degrade organic matter. In order to improve the drilling and feeding efficiency of the subsequent earthworms, the material is loosened. However, in the prior art, the material is only stirred and loosened in the pretreatment stage before the earthworms are added. After the material is loosened, it is easy to re-agglomerate due to sticky components such as fish mucus, which increases the drilling resistance of the earthworms and reduces the feeding efficiency. If the material is loosened after the earthworms are added, the earthworms are also likely to be mechanically damaged, which reduces the survival rate of the earthworms. SUMMARY

[0003] Therefore, the technical problem to be solved by the present application is to provide a water product processing waste fertilizer manufacturing device and a fertilizer manufacturing process, which can perform avoidance loosening treatment on the material after adding earthworms to the water product processing waste fertilizer material, thereby ensuring the survival rate of the earthworms and improving the heavy metal degradation efficiency.

DETAILED DESCRIPTION

[0011] The utility model provides a kind of aquatic product processing waste fertilizer equipment, including processing tank 501, fixed ring 201 is connected on processing tank 501, sliding connection is carried out with slide bar 101 on fixed ring 201, rectangular boss is equipped on slide bar 101, rectangular recess is equipped on fixed ring 201, and slide bar 101 is slidably connected on fixed ring 201 by the cooperation of rectangular boss and rectangular recess, first motor is fixedly connected on fixed ring 201, first lead screw is fixedly connected on the output shaft of first motor, a nut seat is fixedly connected on slide bar 101, first lead screw and the nut seat screw drive on slide bar 101, rotatingly connected with rotating rod 103 on slide bar 101, a through slot is equipped in slide bar 101, rotating rod 103 is inserted into the through slot and is rotatably connected with slide bar 101 by bearing, two pins are inserted on rotating rod 103, and two pins are respectively in contact with the upper and lower ends of slide bar 101, rotating rod 103 is limited by two pins, so that rotating rod 103 can only rotate on slide bar 101, and cannot move up and down, and the second motor is fixedly connected on slide bar 101, the gear is fixedly connected on the output shaft of second motor, the gear ring is fixedly connected on rotating rod 103, the gear and the gear ring are engaged to realize the effect of driving rotating rod 103 to rotate, the connecting plate 104 is fixedly connected on rotating rod 103, and a plurality of stirring rods 105 are rotatably connected on the connecting plate 104, each stirring rod 105 is connected with auxiliary rod 106, processing tank 501 is a tank body, which is closed on the side and bottom, and only the upper side is open, Figure 1 For the convenience of observing internal structure, the processing tank 501 is partially cut away and displayed, when adding materials, the addition operation is carried out from the upper side of the processing tank 501, and after the addition is completed, a cover is used to close the upper side of the processing tank 501 to ensure that the materials do not fly out of the processing tank 501 during the subsequent stirring process.

[0012] The processing tank 501 is filled with aquatic waste materials to be fermented after ethanol addition and pressure filtration treatment, the complex bacteria composed of bacillus subtilis and bacillus licheniformis are added into the processing tank 501, then the rotating rod 103 is continuously rotated on the slide bar 101, thereby driving the connecting plate 104 to continuously rotate, so that the plurality of stirring rods 105 and the plurality of auxiliary rods 106 connected to the connecting plate 104 are synchronously rotated with the connecting plate 104, thereby continuously stirring the materials in the container, so that the original materials and the complex bacteria are uniformly mixed, providing a stable guarantee for the subsequent fermentation operation, in the mixing process, the slide bar 101 can be slid on the fixed ring 201, so as to change the stirring depth and facilitate the overall stirring of the materials in the processing tank 501, improve the mixing effect, and further make the plurality of stirring rods 105 rotate on the connecting plate 104 during the stirring process, thereby changing the inclination angle of the plurality of stirring rods 105, so as to change the shape of the stirring body, provide different stirring effects for the materials, and further improve the mixing effect; After the composite bacteria adding and mixing operation is completed, hot air is circulated into the processing tank 501 by using a circulating fan with a built-in heat source or by adding a heat exchange pipeline outside the pipe body, thereby achieving the effect of adjusting the temperature and humidity in the processing tank 501, providing a good fermentation environment for the fermentation process, and performing subsequent fermentation operations. After the temperature and humidity adjustment is completed, earthworms are added to the outer part of the processing tank 501, thereby utilizing the biological properties of earthworms to degrade heavy metals in the material and improve the subsequent use effect, and accelerating the composting. Before the earthworms are added, the stirring rods 105 are first lifted upward out of the material, and then the stirring rods 105 are rotated on the connecting plate 104 to tilt downward, and then the slide rod 101 is lowered to insert the tilted auxiliary rods 106 into the material. Since the stirring rods 105 have been rotated, the auxiliary rods 106 will not contact the outer ring area of the processing tank 501 where the earthworms have just been added when they are inserted into the material. At this time, the rotating rod 103 is continuously rotated and the slide rod 101 is gradually lowered to stir the area where the earthworms have not been distributed after the earthworms have just been added, thereby performing an early loosening treatment on the area where the earthworms have not been drilled. When the slide rod 101 is lowered to a distance where the connecting plate 104 is far away from the uppermost end surface of the material, the stirring rods 105 can be rotated upward on the connecting plate 104 to the Figure 5 position shown in the figure, and the connecting plate 104 is continuously rotated and the slide rod 101 is continuously lowered, thereby loosening the material in advance after the earthworms are added, thereby reducing the clumping of sticky components such as fish innards and crustacean waste in the aquatic waste, and reducing the earthworm drilling resistance by dispersing the material to promote uniform distribution and feeding efficiency. At the same time, since the loosening operation of the present device is performed after the earthworms are added, compared with the prior art which first performs stirring and loosening before the earthworms are added, the present device can effectively reduce the time interval between the earthworms and the loosened material, thereby effectively avoiding the secondary condensation of the material after loosening, and preventing the occurrence of the earthworm drilling condition. Through the rotatable arrangement of the stirring rods 105 and the outer ring addition of the earthworms, the stirring rods 105 and the auxiliary rods 106 will not contact the earthworms just added when the loosening treatment is performed after the earthworms are added, thereby avoiding damage to the earthworms. Thus, the effect of loosening after the earthworms are added is achieved while avoiding damage to the earthworms during the loosening process, ensuring the normal drilling and feeding of the earthworms in the future. That is, the earthworms are only added to the outer ring area of the processing tank 501, avoiding the stirring core area, thereby avoiding mechanical damage to the earthworms. The stirring rods 105 are first lifted and then tilted and inserted after the earthworms are added, which can avoid direct contact with the earthworms and ensure their survival rate. The auxiliary rods 106 loosen the area where the earthworms have not been distributed by lowering the slide rod 101, reducing the drilling resistance and promoting uniform distribution of the earthworms.

[0013] Further comprising a matching frame 301 fixed on the slide rod 101, a transmission ring 302 is slidably connected on the matching frame 301, two cylindrical rods are fixed on the transmission ring 302, two through holes are arranged on the matching frame 301, and the slide connection between the matching frame 301 and the transmission ring 302 is completed through the cooperation of the two cylindrical rods and the two through holes, and a first electric push rod capable of driving the transmission ring 302 to slide is fixed on the matching frame 301. A torsional spring is arranged at the rotating connection between each stirring rod 105 and the connecting plate 104.

[0014] Under normal circumstances, the plurality of stirring rods 105 are resisted by the torsional force of the torsional spring and abut against the transmission ring 302, when it is necessary to operate the plurality of stirring rods 105 to rotate, the transmission ring 302 is caused to slide on the matching frame 301, and then the transmission ring 302 is used to provide downward pressure for the plurality of stirring rods 105, so that the plurality of stirring rods 105 overcome the torsional force of the torsional spring and rotate on the connecting plate 104, thereby achieving the effect of changing the angle of the stirring rod 105, and providing driving for the subsequent improvement of the stirring effect and the effect of avoiding the position where the earthworms are just added; The angle-adjustable characteristic of the stirring rod 105 causes the material to be subjected to shearing force and overturning action in different directions, avoids the "dead angle" problem of traditional fixed-angle stirring, and improves the mixing uniformity; Since the matching frame 301 is fixed on the slide rod 101, the matching frame 301 does not rotate with the rotating rod 103, the first electric push rod driving the transmission ring 302 to slide does not continuously rotate, line entanglement is effectively avoided, and the circular ring shape of the transmission ring 302 enables the transmission ring 302 to press the plurality of stirring rods 105 to rotate regardless of the posture of the connecting plate 104 when the transmission ring 302 slides downward, that is, the circular ring structure of the transmission ring 302 is adapted to any rotating angle of the connecting plate 104, always maintains uniform pressure on the stirring rods, guarantees the reliability of the adjusting action, and brings convenience for subsequent driving operation.

[0015] Water product waste example 1 processed by using the processing tank 501: The water product waste includes fish viscera, fish organs, bones, minced meat and fish skin and other wastes generated in the processing process, and the utilization effect of the water product processing waste is achieved by composting the above-mentioned waste.

[0016] Water product waste example 2 processed by using the processing tank 501: The water product waste includes fish excrement, leftover feed, dead fish and pond bottom sludge and other wastes generated in the breeding and processing process, and the utilization effect of the water product breeding and processing waste is achieved by composting the above-mentioned waste.

[0017] A plurality of auxiliary rods 106 are respectively slidably connected to a plurality of stirring rods 105, the stirring rod 105 is composed of an elongated rod and a thick rod, the auxiliary rod 106 is provided with a rectangular slot, the plurality of stirring rods 105 are slidably connected to the plurality of auxiliary rods 106 by the cooperation of the elongated rod and the slot opening of the rectangular slot, each stirring rod 105 is fixedly connected with a rectangular plate, each rectangular plate is fixedly connected with a second electric push rod, each auxiliary rod 106 is fixedly connected with a rectangular plate, the extension rods of the plurality of second electric push rods are respectively fixedly connected with the plurality of rectangular plates, each stirring rod 105 is fixedly connected with a battery, the plurality of second electric push rods are powered by the plurality of batteries, avoiding line entanglement, in actual use, in order to ensure the comprehensiveness of the stirring of the materials in the processing tank 501, the lengths of the stirring rod 105 and the auxiliary rod 106 are greater than 20 cm, and sufficient installation space is provided for the second electric push rod and the battery.

[0018] During the stirring process, the plurality of auxiliary rods 106 can be periodically slid on the plurality of stirring rods 105, and the plurality of stirring rods 105 can be rotated on the connecting plate 104, so that the plurality of stirring rods 105 and the plurality of auxiliary rods 106 can further stir the materials in different shapes, which can further facilitate the uniform mixing of the materials. Spiral: the stirring rod 105 is driven to rotate around the axis by the rotating rod 103, and is slid upward on the slide rod 101, so that the materials can be stirred in a spiral trajectory to move part of the materials, eliminate the stratification of the materials, form a convection cycle after the materials are stirred, improve the stirring effect, increase the contact area of the bacillus subtilis and the aquatic waste, and destroy the fish mucus by spiral shear force to inhibit the formation of lumps, and the spiral angle is changed by changing the inclination angle of the stirring rod 105 to further enrich the spiral stirring effect of the materials. Shearing: when the stirring rod 105 is inclined and rotates with the rotating rod 103, the edge of the stirring rod 105 and the contact surface of the materials produce shear force, which further destroys the fish mucus, and the shear action can expand the diffusion channel of the bacterial solution and improve the permeability of the bacterial solution in the materials, the heat energy generated by shear friction can stimulate the activity of microorganisms and shorten the fermentation start-up time, and the relative displacement difference between the auxiliary rod 106 and the stirring rod 105 can produce shear stress and improve the shearing effect, and the shearing area depth is changed by the upward and downward sliding of the slide rod 101 to adapt to the processing needs of materials with different viscosities. Impact: The lateral displacement impact force generated by the sliding of the auxiliary rod 106 can assist in breaking large fish bones and shell fragments, and the pores generated by the impact can further improve the penetration rate of the bacterial solution in the material. The impact action is concentrated in the inner circle of the material, which can avoid the outer circle of the earthworm activity area and reduce the mechanical damage to the earthworms. At the same time, when the inclination angle is adjusted, high-frequency collisions are formed between the edges of the stirring rod 105 and the material, which further improves the impact effect. Combined with the oxygen blowing of the air inlet rod 304, the impact action enhances the looseness of the material and reduces the risk of blockage in the shear zone. When loosening treatment is performed after the addition of earthworms, the plurality of auxiliary rods 106 can also slide on the plurality of stirring rods 105 to adjust the stirring range of the plurality of auxiliary rods 106, further avoiding contact between the plurality of auxiliary rods 106 and the plurality of stirring rods 105 and the addition area of the earthworms during the loosening treatment process, and ensuring the survival state of the earthworms.

[0019] The air inlet rod 304 is also fixed on the transmission ring 302, and the air inlet rod 304 is fixed with a blowing ring 303. A plurality of air outlets are formed on the lower side of the blowing ring 303. An air inlet is formed on the air inlet rod 304. The air inlet rod 304 and the blowing ring 303 are both hollow structures. The hollow structure of the air inlet rod 304 is in communication with the hollow structure of the blowing ring 303. The air inlet on the air inlet rod 304 is connected with a gas pump capable of pumping oxygen through a hose. Each air outlet is provided with a rubber plug that can be opened and closed. When the gas is blown out, the rubber plug will be deformed, and the gas will be blown out through the rubber plug. When there is no gas blowing out, the rubber plug can be automatically closed to avoid external materials entering the blowing ring 303. The above-mentioned rubber plug is very common in the prior art and has many application scenarios, such as the anti-pollution structure in the shower. Therefore, it will not be described here.

[0020] During the stirring process, oxygen is injected into the air inlet rod 304 through the hose and blown out through the plurality of air outlets, so that the material at the sliding connection position between the plurality of stirring rods 105 and the plurality of auxiliary rods 106 is blown away, thereby effectively avoiding the material from being blocked at the sliding connection position between the plurality of stirring rods 105 and the plurality of auxiliary rods 106 during the operation of the equipment, reducing the number of subsequent manual cleaning and maintenance, and bringing convenience for subsequent actual use. At the same time, during the fermentation process, oxygen can also be blown out through the plurality of air outlets at regular intervals, and the sliding rod 101 can reciprocate up and down, thereby periodically supplementing oxygen to the inside of the fermented material, thereby achieving the effects of promoting oxygen penetration and preventing anaerobic spoilage.

Meanwhile, the plurality of shielding parts 401 can also shield the sliding connection position, and further improve the effect of avoiding blockage. Meanwhile, due to the arc-shaped arrangement of the plurality of shielding parts 401, even if the plurality of stirring rods 105 rotate on the connecting plate 104, the plurality of shielding parts 401 can always shield the sliding connection position between the plurality of stirring rods 105 and the plurality of auxiliary rods 106, and further continuously ensure the effect of avoiding blockage. Due to the rotatable arrangement of the plurality of shielding parts 401, when the plurality of stirring rods 105 rotate synchronously with the connecting plate 104, the plurality of shielding parts 401 will rotate synchronously with the plurality of stirring rods 105, so as to further ensure the continuous shielding and guiding effect.

At the same time, the plurality of stirring rods 105 can rotate on the connecting plate 104 during the cleaning process, so that the two scraping rods 602 scrape the stirring rod 105 at different angles, provide different angle contact effects for the adhered material, facilitate the scraping of the material in different adhesion areas, and improve the cleaning effect.
