[0002] Farmers' markets generate a large amount of leftover vegetables and fruits during their daily operations. Directly discarding these materials can easily cause environmental pollution. However, after fermentation, the fermentation liquid can be extracted for the production of organic fertilizers and biological agents, achieving resource recycling. Fermentation liquid separation is a crucial step in the resource-based treatment of leftover vegetables and fruits, but existing separation devices have significant drawbacks: firstly, the extrusion structure design is simplistic, mostly single-layer extrusion, resulting in insufficient material extrusion and low fermentation liquid recovery rates; secondly, the lack of effective buffering mechanisms during extrusion leads to uneven material stress, easily clogging the equipment, and the high impact force causes rapid equipment wear. Therefore, improvements to existing technologies are needed. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, a device for separating fermented liquid from leftover vegetables and fruits in a farmers' market includes a frame 1. A separation shell 2 is mounted on the upper end of the frame 1. A separation shaft 6 is mounted inside the separation shell 2. A spiral extrusion plate 13 is mounted on the outside of the separation shaft 6. Separation extrusion plates 5 are evenly and equidistantly installed from left to right inside the separation shell 1. Buffer components are installed on both sides of the front end of the separation extrusion plates 5. Buffer extrusion plates 16 are installed at the ends of the buffer components. Through holes 17 are opened at the center of both the separation extrusion plates 5 and the buffer extrusion plates 16. The separation shaft 6 is disposed in the through hole 17.

[0017] In practical implementation, the equipment frame 1 is made of welded carbon steel, and anti-slip pads or fixing bolts can be added to the bottom to ensure the stability of the equipment during operation. Its height is suitable for the daily operation of farmers' markets (recommended height 80-100cm). The separating shell 2 is made of 304 stainless steel, which has the characteristics of corrosion resistance and easy cleaning. The inner wall is smooth to reduce material residue. The shell cross-section is U-shaped or cylindrical, and the length is adapted according to the number of separating extrusion plates 5 installed (the spacing between each separating extrusion plate is recommended to be 8-12cm). The separating shaft 6 is made of 45 steel with heat treatment and chrome plating for rust prevention. The gap between its diameter and the inner diameter of the through hole 17 is controlled at 0.5-1mm to avoid excessive friction with the separating extrusion plates 5 and the buffer extrusion plates 16 during operation. The spiral extrusion plate 13 is fixed to the separating shaft 6 by welding or high-strength bolts. The spiral helix angle is designed to be 15-20°, which can efficiently push the material from left to right while gradually increasing the extrusion pressure. The separation extrusion plate 5 is fixed to the inner wall of the separation shell 2 by bolts. The plate has several filter holes (1-2mm in diameter) for the permeation and separation of fermentation broth. The buffer extrusion plate 16 is arranged parallel to the separation extrusion plate 5. The plate also has filter holes and the edges are rounded to prevent scratching the material or the shell.

[0018] In some technical solutions, the buffer assembly includes a buffer body 18, a buffer spring 20 is installed inside the buffer body 18, a bearing plate 19 is installed at the end of the buffer spring 20, and a connecting plate 21 is installed on the side walls of the buffer body 18 and the bearing plate 19 through a snap-fit ​​mechanism. One side of the connecting plate 21 is fixedly connected to the separation compression plate 5, and the other side of the connecting plate 21 is fixedly connected to the buffer compression plate 16.

[0019] In the specific implementation process, the buffer body 18 is a hollow cuboid structure, made of engineering plastic or aluminum alloy, with a pre-reserved mounting cavity for the buffer spring 20. The inner wall of the cavity is lubricated to reduce the resistance of the spring movement. The buffer spring 20 is made of stainless steel, with an elastic coefficient set to 5-10 N / mm according to the required extrusion force. In its natural state, its length is slightly longer than the internal mounting cavity of the buffer body 18 to ensure that it is always in a pre-tightened state after assembly, achieving effective buffering. The bearing plate 19 is a rectangular steel plate (3-5 mm thick), which fits with the internal mounting cavity of the buffer body 18 with a clearance to ensure smooth sliding under the action of spring force. The connecting plate 21 is made of the same steel plate as the bearing plate 19 and is fixed to the separation extrusion plate 5 and the buffer extrusion plate 16 by welding or bolts, respectively. The connection is reinforced to prevent it from falling off during the extrusion process.

[0020] In some technical solutions, the locking mechanism includes an I-shaped slot 22 formed on the side wall of the buffer body 18 and the bearing plate 19 and an I-shaped block 23 installed on the side wall of the connecting plate 21, with the I-shaped block 23 locking into the I-shaped slot 22.

[0021] In practical implementation, the I-shaped slot 22 is formed by milling, and the gap between the slot width and the thickness of the I-shaped block 23 is controlled at 0.1-0.2mm, ensuring both a firm connection and easy assembly / disassembly. The I-shaped block 23 is integrally formed or welded to the connecting plate 21, and its length is adapted to the depth of the I-shaped slot 22 (5-8mm recommended). After engagement, the end of the block fits snugly against the bottom of the slot to prevent loosening. To improve connection stability, threaded holes can be opened on the side wall of the I-shaped slot 22. After assembly, the I-shaped block 23 is tightened with set screws to prevent the connection from falling off due to vibration during equipment operation.

[0022] In some technical solutions, the buffer body 18 has balance cavities 24 at both ends of its sidewall, and the bearing plate 19 has balance rods 25 installed at both ends of its sidewall, with the balance rods 25 inserted into the balance cavities 24.

[0023] In practical implementation, the balance cavity 24 is a cylindrical hole, opened at both ends of the side wall of the buffer body 18. The diameter of the hole is 0.05-0.1mm larger than the diameter of the balance rod 25, ensuring that the balance rod can extend and retract flexibly without shifting. The balance rod 25 is made of stainless steel round rod, with one end welded to the side wall of the bearing plate 19 and the other end inserted into the balance cavity 24. Its length is designed to be 1.2-1.5 times the length of the buffer body 18, ensuring that a part of the rod remains in the balance cavity when the bearing plate 19 moves, preventing it from detaching. The surface of the balance rod 25 is polished to reduce frictional wear with the inner wall of the balance cavity 24 and extend its service life.

[0024] In some technical solutions, a balance plate 26 is installed at the end of the balance bar 24, and the balance plate 26 is set inside the balance cavity 24.

[0025] In the specific implementation process, the balance plate 26 is a circular steel plate (the diameter is slightly smaller than the inner diameter of the balance cavity 24 by 0.1mm), which is welded and fixed to the end of the balance rod 25. Its function is to limit the extension and retraction of the balance rod 25 and prevent the balance rod from detaching from the balance cavity 24. The surface of the balance plate 26 is smoothed and fits against the inner wall of the balance cavity 24, which can help to share the lateral force of the buffer spring 20, further ensuring the stability of the movement of the bearing plate 19 and preventing the buffer assembly from tilting.

[0026] In some technical solutions, drive shafts 14 are installed at both ends of the separating shaft 6. A bearing housing 15 is installed at one end of the drive shaft 14. The bearing housing 15 is installed inside the separating housing 2. A drive motor 10 is installed on the right side wall of the separating housing 2. A coupling 11 is installed at the drive end of the drive motor 10. A bearing sleeve 12 is installed on the right side wall of the separating housing 2. The drive shaft 14 on the other side passes through the bearing sleeve 12 and is connected to the coupling 11.

[0027] In practical implementation, the drive shaft 14 and the separation shaft 6 are integrally formed or connected by a coupling. The material is the same as that of the separation shaft 6, and the diameter is adapted according to the equipment power (20-30mm recommended). The bearing housing 15 is a deep groove ball bearing, which is fixed to the bearing housing mounting seat on the left side wall inside the separation housing 2 by bolts. The bearing is filled with grease to reduce the frictional resistance during shaft operation. The drive motor 10 is a variable frequency geared motor (power 0.75-2.2kW), which is fixed to the right side wall of the separation housing 2 by a motor mounting seat. The motor speed can be adjusted according to the material extrusion requirements (50-150r / min recommended). The coupling 11 is a flexible coupling, which can compensate for the installation coaxiality error between the drive motor 10 and the drive shaft 14, and at the same time buffer the vibration during operation. The bearing sleeve 12 is a cylindrical sleeve, welded to the opening on the right side wall of the separation housing 2, and equipped with a sealed bearing inside, which both supports the drive shaft 14 and prevents the fermentation liquid from leaking.

[0028] In some technical solutions, a liquid receiving box 8 is installed at the bottom of the equipment frame 1, a liquid guide plate 9 is provided at the bottom of the inner part of the separation shell 2, a filter hole is provided on the surface of the liquid guide plate, the bottom of the liquid guide plate 9 is connected to the liquid receiving box 8, a feed hopper 3 is installed at the upper end of the separation shell 2, and a discharge port 4 is installed at the front end of the separation shell 2.

[0029] In the specific implementation process, the liquid receiving box 8 is a cuboid structure with an open top, made of 304 stainless steel, and fixed to the bottom of the equipment frame 1 with bolts. Its length is the same as that of the separation shell 2, and its width is slightly larger than the outlet width of the guide plate 9 to ensure complete collection of fermentation liquid. A drain port with a valve is set at the bottom of one side of the liquid receiving box 8 for easy periodic cleaning of residual impurities. The guide plate 9 is an inclined stainless steel plate (inclination angle 15-30°), fixed to the bottom of the separation shell 2 by welding, with evenly spaced filter holes (pore diameter 0.5-1mm) on its surface for secondary filtration of solid impurities in the fermentation liquid. The lower end of the guide plate 9 extends to the drain port on the side wall of the separation shell 2, and the drain port is connected to the liquid receiving box 8 through a pipe. The pipe connection is sealed to prevent leakage. The feed hopper 3 is a funnel-shaped structure made of stainless steel, and is fixed to the upper left side of the separation shell 2 by welding or bolts. The edge of the feed port is flanged to facilitate feeding and prevent material spillage. The discharge port 4 is located on the front right side of the separation shell 2. It is a rectangular opening equipped with a movable baffle or valve, which can adjust the size of the opening and control the discharge speed according to the waste discharge situation.

[0030] Working Principle: Waste material from vegetables and fruits enters the separation shell from the feed hopper. The drive motor, via a coupling and drive shaft, rotates the separation shaft. The spiral extrusion plate rotates with the shaft, propelling the material along the separation shell from left to right. During this movement, the material is subjected to progressive compression by the spiral extrusion plate, multiple separation extrusion plates, and buffer extrusion plates. The buffer springs in the buffer assembly, through the bearing plate and connecting plate, cause the buffer extrusion plate to adaptively adjust the pressure. The balance rod and balance plate ensure stable buffering and prevent clogging. The extruded fermentation liquid passes through the filter holes of the separation extrusion plate, buffer extrusion plate, and guide plate, and flows into the collection box for collection. The extruded waste residue is finally discharged from the discharge port, completing the separation of fermentation liquid and residue.
