Description
Technical Field
[0001] This invention belongs to the field of waste liquid treatment technology, and specifically discloses a device for collecting and recycling edible fungi fermentation waste liquid. Background Technology
[0002] Edible fungi refer to large, edible mushrooms, also known as macrofungi, commonly called mushrooms. Edible fungi cultivation is a method of vegetable cultivation that involves artificially creating suitable conditions such as temperature, light, water, nutrients, and gases, and cultivating large edible fungi on artificially prepared culture media. Currently, more and more edible fungi are cultivated artificially. The fungi are fermented into colonies, providing optimal nutrition, pH, temperature, and oxygen supply for mycelial growth, allowing the mycelium to grow and proliferate rapidly, reaching a certain number of mycelial balls in a short time. These colonies are then placed in a culture medium for planting. The fermentation process generates waste liquid, which requires treatment.
[0003] Existing methods for collecting and recycling edible fungi fermentation waste liquid present challenges. When the waste liquid is discharged into the waste liquid tank, the mycelial residues, which have a certain degree of stickiness and adhesion, gradually adhere to the inner wall and bottom of the collection tank. This easily leads to the growth of various bacteria, molds, and other microorganisms. The massive reproduction of these microorganisms consumes oxygen in the waste liquid, resulting in the formation of an anaerobic environment and the generation of odors. These odors not only pollute the working environment and affect the health of operators but may also have adverse effects on the surrounding environment, causing environmental problems and increasing the difficulty of treatment. Summary of the Invention

The large-scale reproduction of these microorganisms will consume the oxygen in the waste liquid, leading to the formation of an anaerobic environment, which in turn produces an odor. The odor not only pollutes the working environment and affects the health of the operators, but may also have an adverse impact on the surrounding environment, causing environmental problems and increasing the difficulty of treatment.

[0026] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.
[0028] like Figures 1-9 The device for collecting and recycling edible fungi fermentation waste liquid includes a waste liquid tank 1, which is rectangular. Inside the waste liquid tank 1, there is a rectangular collection chamber. A first scraping mechanism 11 is provided on the side of the collection chamber to remove mycelial residues from the side surface of the collection chamber. A second scraping mechanism 12 is provided in the middle of the collection chamber to remove mycelial residues from the bottom surface of the collection chamber. Inclined surfaces 34 are provided at both ends of the bottom of the collection chamber. By setting the first scraping mechanism 11 and the second scraping mechanism 12, the side surface and bottom surface of the collection chamber can be cleaned respectively, which can remove mycelial residues attached to the inner wall and bottom surface of the collection chamber in a timely and effective manner, preventing them from accumulating in large quantities. Furthermore, by setting the inclined surfaces 34, cleaning dead corners can be minimized, ensuring that the corners inside the collection chamber can be cleaned.
[0029] Both sides of the waste liquid tank 1 are bolted with fixing strips 2. Each fixing strip 2 has a first groove 3 on its surface. A lead screw 4 and a guide rod 5 are respectively installed inside the two first grooves 3. A support bracket 6 is bolted to the end of one of the fixing strips 2. A stepper motor 7 is mounted on the surface of the support bracket 6, and the output end of the stepper motor 7 is connected to the lead screw 4. A drive block 8 is slidably mounted above each of the two fixing strips 2. A first slider 9 is provided at the bottom of each drive block 8. The two first sliders 9 are respectively fitted onto the surfaces of the lead screw 4 and the guide rod 5. The two drive blocks 8 are symmetrical to each other, and a smooth rod 10 is fixedly connected between them. When the stepper motor 7 is powered on, its output end drives the lead screw 4 to rotate. Because the lead screw 4 and the first slider 9 at the bottom of the drive block 8 are fitted together... The guide rod 5 serves as a guide. Driven by the rotation of the lead screw 4, the drive block 8 slides along the first sliding groove 3 on the surface of the lead screw 4 and the guide rod 5. The two drive blocks 8 are symmetrical to each other and are fixedly connected by a smooth rod 10. When one drive block 8 moves, the smooth rod 10 will drive the other drive block 8 to move synchronously, thereby ensuring the consistency and stability of the movement of the two drive blocks 8. The stepper motor 7 is used as the power source, which can accurately control the rotation angle and speed of the lead screw 4, and thus accurately control the movement position and speed of the drive block 8. The setting of this mechanism can simultaneously drive the first scraping mechanism 11 and the second scraping mechanism 12 to work, which can ensure that the scraping work is carried out according to the predetermined program and precision, and improve the effect and quality of cleaning mycelial residues on the inner wall of the liquid collection tank.
[0030] The first scraping mechanism 11 includes a rectangular frame 16, which is movably installed inside the liquid collection chamber. A cover frame 17 is bolted to the surface of the rectangular frame 16. A first scraper 18 is installed on the side of the cover frame 17. The first scraper 18 is inclined and its end is close to the inner wall of the liquid collection chamber. The rectangular frame 16 can move up and down inside the liquid collection chamber. During the movement of the rectangular frame 16, the first scraper 18 installed on the side of the cover frame 17 moves with the rectangular frame 16. The inclined end of the first scraper 18 is in close contact with the inner wall of the liquid collection chamber. As the rectangular frame 16 moves, the scraper continuously scrapes the inner wall of the liquid collection chamber, scraping off the mycelial residues attached to it.
[0031] Two connecting rods 15 are symmetrically rotated on the surface of the bare rod 10. The other end of the connecting rod 15 is connected to the middle of the rectangular frame 16 through a rotating shaft. When the bare rod 10 moves above the waste liquid tank 1, the connecting rods 15 symmetrically rotated on its surface will swing with the movement of the bare rod 10. The other end of the connecting rod 15 is connected to the middle of the rectangular frame 16 through a rotating shaft. The swing of the connecting rod 15 will drive the rectangular frame 16 to make a linear reciprocating motion along the inner wall of the liquid collection chamber, thereby enabling the first scraper 18 installed on the rectangular frame 16 to perform a scraping operation on the side surface of the liquid collection chamber and remove the mycelial residues on the side surface of the liquid collection chamber.
[0032] The second scraping mechanism 12 includes a rectangular block 21, which is fixedly sleeved in the middle of the polished rod 10. A third groove 23 is provided at the bottom of the rectangular block 21. A vertical rod 24 is provided below the rectangular block 21, and its top is slidably installed in the third groove 23. Two protrusions 25 are symmetrically installed at the bottom of the vertical rod 24. Grooves 26 are provided on the end faces of the protrusions 25. A vertical plate 27 is provided on the side of the protrusions 25. A slider is provided on the surface of the vertical plate 27 near the protrusions 25, and the slider is slidably installed in the groove 26. A second scraper 28 is installed at the bottom of the vertical plate 27. The polished rod 10 moves horizontally under the drive of the drive block 8. Because the rectangular block 21 is fixedly sleeved in the polished rod 10… Therefore, the rectangular block 21 moves together with the smooth rod 10, thereby providing power for the overall movement of the second scraping mechanism 12. As the smooth rod 10 moves horizontally, it drives the rectangular block 21, the vertical rod 24, the protruding block 25, the vertical plate 27 and the second scraper 28 connected below it to move together. During the movement, the second scraper 28 scrapes off the mycelial residue on the bottom surface of the liquid collection tank. At the same time, under the action of the third chute 23, the inner wall of the third chute 23 pushes the top of the vertical rod 24. When the rectangular block 21 moves to the end of the waste liquid tank 1, the second scraper 28 will move to the end of the liquid collection tank to avoid dead corners in cleaning. At the same time, the rectangular block 21 will not occupy too much space on the top of the waste liquid tank 1.
[0033] Side plates 29 are fixedly installed on the top of the adjacent surfaces of the two second scrapers 28. A central groove 30 is opened inside the vertical rod 24. A spring 31 is installed inside the central groove 30. A T-shaped column 32 is connected to the bottom of the spring 31. The surface of the T-shaped column 32 moves through the bottom of the vertical rod 24. A connecting block 33 is fixedly installed at the bottom of the T-shaped column 32. An opening is opened on the surface of the connecting block 33. The opening is fixedly snapped onto the surface of the side plate 29. The spring 31 and the T-shaped column 32 inside the vertical rod 24 form an elastic component. The elasticity of the spring 31 allows the T-shaped column 32 to move up and down inside the vertical rod 24, thereby driving the connecting block 33 and the side plate 29 snapped onto it to make slight up and down adjustments. This allows the second scrapers 28 to better adapt to the bottom surface of the liquid collection tank. When cleaning the surface of the inclined surface 34, the second scrapers 28 can automatically adjust their height under the action of the spring 31 to always maintain good contact with the inclined surface 34 and ensure the consistency of the scraping effect.
[0034] A frame 19 is provided at the middle of the top of the waste liquid tank 1. The ends of the frame 19 are bolted to the waste liquid tank 1. A second sliding groove 20 is provided on the surface of the frame 19. A protruding post 22 is fixedly installed on the top of the rectangular block 21. The surface of the protruding post 22 is slidably installed in the second sliding groove 20. The protruding post 22 slides in the second sliding groove 20, which further restricts the movement trajectory of the rectangular block 21. The frame 19 is bolted to the middle of the top of the waste liquid tank 1, providing an additional support structure for the rectangular block 21 and the entire second scraping mechanism 12. This helps to disperse the force generated by the second scraping mechanism 12 during operation, reduce the pressure borne by the polished rod 10 alone, make the whole device more stable, and reduce the risk of component damage caused by vibration or scraping force.
[0035] A liquid outlet is provided at the middle of the bottom of the liquid collection tank. A filter screen 14 is installed on the surface of the liquid outlet. A liquid outlet pipe 13 is installed at the bottom of the waste liquid tank 1 and is connected to the liquid outlet. During the collection of waste liquid, the small holes on the filter screen 14 can effectively intercept solid substances such as mycelial residues and impurities, allowing only liquid to pass through, thereby achieving solid-liquid separation. The liquid outlet serves as the channel for waste liquid to flow out of the liquid collection tank and is tightly connected to the liquid outlet pipe 13 to ensure the sealing of the entire collection and recovery device. At the same time, when the second scraping mechanism 12 is working, it can scrape off the solid substances such as mycelial residues and impurities remaining on the surface of the filter screen 14 to ensure the efficiency of liquid discharge.
[0036] Working principle:
[0037] First, the fermentation waste liquid of edible fungi is flowed into the collection chamber of waste liquid pool 1;
[0038] Next, the stepper motor 7 starts, and its output drives the lead screw 4 to rotate. Since the lead screw 4 cooperates with the first slider 9 at the bottom of the drive block 8, and the guide rod 5 plays a guiding role, the drive block 8 slides along the first slide groove 3 on the surface of the lead screw 4 and the guide rod 5 under the rotation drive of the lead screw 4. The two drive blocks 8 are connected by the guide rod 10. When one drive block 8 moves, it drives the other drive block 8 to move synchronously through the guide rod 10. When the guide rod 10 moves, the connecting rod 15, which is symmetrically rotated on its surface, swings with the movement of the guide rod 10. The other end of the connecting rod 15 is connected to the guide rod 10. The rectangular frame 16 is connected to the middle of the pivot shaft. The swing of the connecting rod 15 drives the rectangular frame 16 to move back and forth in a straight line along the inner wall of the liquid collection chamber. During the movement of the rectangular frame 16, the inclined first scraper 18 installed on the side of the cover frame 17 moves along with it. Its end is in close contact with the inner wall of the liquid collection chamber, and it continuously scrapes the inner wall of the liquid collection chamber to remove the attached mycelial residue. The bare rod 10 drives the rectangular block 21 fixedly sleeved in the middle to move horizontally in a straight line. The rectangular block 21 drives the vertical rod 24, the protruding block 25, the vertical plate 27 and the second scraper 28 connected below to move. During its movement, the second scraper 28 scrapes away mycelial residues on the bottom surface of the collection tank. As the rectangular block 21 moves, the inner wall of the third chute 23 pushes the top of the vertical rod 24, allowing the second scraper 28 to move to the end of the collection tank when the rectangular block 21 moves to the end of the waste liquid pool 1, thus avoiding cleaning dead corners. At the same time, the elastic component composed of the spring 31 and the T-shaped column 32 inside the vertical rod 24 allows the T-shaped column 32 to move up and down within the vertical rod 24, driving the connecting block 33 and the side plate 29 to make slight up and down adjustments, so that the second scraper 28 can adapt to the bottom surface of the collection tank. When cleaning the inclined surface 34, it automatically adjusts its height to maintain good contact with the inclined surface 34. Furthermore, when the second scraping mechanism 12 is working, it can also scrape away mycelial residues, impurities, and other solid substances remaining on the surface of the filter screen 14, ensuring liquid discharge efficiency.
[0039] With the cooperation of the first scraping mechanism 11 and the second scraping mechanism 12, when the rectangular frame 16 moves to the bottom position of the liquid collection tank, the vertical plate 27 will move to the middle position of the liquid collection tank and the vertical plate 27 will descend as a whole. At this time, the top of the vertical plate 27 and the top of the inclined surface 34 are on the same horizontal line. Thus, when the rectangular frame 16 descends, the end of the first scraper 18 can move from the initial position at the top of the liquid collection tank to the angle between the top of the inclined surface 34 and the inner wall of the liquid collection tank. The first scraper 18 and the second scraper 28 will come into contact, but there will be no violent collision that would cause damage to the first scraper 18 and the second scraper 28.
