Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figures 1-3 In Embodiment 1 of the present invention, a structural diagram of a filter press device for feed processing is provided. The filter press device for feed processing includes: a crushing box 14, which is used to crush kitchen waste; and a separation box 1, the interior of which is connected to the discharge port of the crushing box 14, for separating liquid from kitchen waste.

[0036] An eccentrically rotating shaft 2 is installed inside the separation tank 1, and the bottom of the separation tank 1 is provided with a liquid passage structure for the filtrate;

[0037] A circumferential array of partitions 3 is arranged on the surface of the rotating shaft 2. The end of the partition 3 away from the rotating shaft 2 abuts against the inner wall of the separation box 1. The multiple partitions 3 divide the interior of the separation box 1 into multiple independent processing chambers. The partitions 3 are elastically slidably arranged on the rotating shaft 2.

[0038] Multiple intermediate filter sleeves 4 are flexibly rotatably installed inside the separation box 1. The intermediate filter sleeves 4 are used to filter the waste in the middle of the processing chamber. The bottom of the separation box 1 is also provided with a groove 5, which is used to accommodate the intermediate filter sleeves 4 in the tilted state.

[0039] And, a discharge port 12 is provided on the separation box 1, and a crushing component for crushing kitchen waste is provided on the discharge port 12.

[0040] The crushing box 14 contains a crushing shaft and crushing blades mounted on the crushing shaft. The internal structure is existing technology and will not be described in detail here.

[0041] Specifically, the crushing chamber 14 crushes the kitchen waste, and then the crushed kitchen waste enters the separation chamber 1. Due to the eccentric setting of the rotating shaft 2, the kitchen waste entering the separation chamber 1 first enters the processing chamber when it is at its maximum size. As the rotating shaft 2 rotates, the processing chamber gradually decreases in size, thus pressing and filtering the kitchen waste. This allows the liquid to be discharged through the structure at the bottom of the separation chamber 1. During the processing, when the waste passes through the intermediate filter sleeve 4, the intermediate filter sleeve 4 can also filter out the liquid in the kitchen waste located in the middle of the processing chamber. When the partition 3 comes into contact with the intermediate filter sleeve 1... When the intermediate filter sleeve 4 is in place, it deflects and enters the groove 5, allowing the partition 3 to pass through. When the partition 3 leaves the intermediate filter sleeve 4, the intermediate filter sleeve 4 returns to a vertical state under the action of elasticity, and then filters out the liquid in the kitchen waste in the middle position of the next processing chamber. When the processing chamber moves to the minimum space state, it has completed the filtration of kitchen waste, and then passes through the discharge port 12. The crushing component in the discharge port 12 crushes the compressed kitchen waste, so that the kitchen waste can be completely discharged through the discharge port 12, avoiding the kitchen waste from entering the processing chamber again for repeated pressing and filtration.

[0042] This invention uses a rotating shaft 2 to drive the partition 3 to rotate, causing the internal space of the processing chamber to change periodically. This allows for continuous filtration of liquid from the kitchen waste produced by the crushing box 14. During the changing process, the filter residue can also be discharged, making it convenient to use. By elastically rotating an intermediate filter sleeve 4 at the bottom of the separation box 1 and setting a groove 5, the intermediate filter sleeve 4 can quickly filter out the liquid in the middle of the processing chamber, thus improving the filtration efficiency. By setting a crushing component on the discharge port 12, the crushing component breaks down the compressed kitchen waste, allowing the kitchen waste to be completely discharged through the discharge port 12, preventing the kitchen waste from re-entering the rotating shaft 2 for repeated filtration.

[0043] like Figure 2As shown, in another preferred embodiment of the present invention, the crushing component includes a crushing shaft 7 rotatably mounted on the separation box 1, and a plurality of crushing blades 8 are arrayed on the crushing shaft 7. The crushing blades 8 are positioned at the passage of the processing chamber, so that the crushing blades 8 can crush the kitchen waste passing through, preventing the kitchen waste from being incompletely discharged.

[0044] In order to enable the crushing shaft 7 to drive the crushing blade 8 to rotate when the partition 3 passes through the crushing blade 8, a drive assembly for driving the crushing shaft 7 to rotate intermittently is also provided between the rotating shaft 2 and the crushing shaft 7.

[0045] like Figure 2 As shown, in another preferred embodiment of the present invention, the drive assembly includes a gear 22 and a plurality of racks 23. The plurality of racks 23 are arranged in a circumferential array on the outside of the rotating shaft 2. The gear 22 is fixedly sleeved on the crushing shaft 7. The plurality of racks 23 intermittently mesh with the gear 22. The racks 23 are correspondingly arranged with the partition 3 and are positioned below the partition 3. Thus, when the partition 3 approaches the crushing blade 8, the racks 23 mesh with the gear 22, causing the crushing blade 8 to rotate as the partition 3 passes by, thereby preventing the partition 3 from colliding with the crushing blade 8. This effectively protects the partition 3.

[0046] To improve the pulverizing effect, the pulverizing shaft 7 is oscillatingly mounted on the separation box 1. Specifically, the pulverizing shaft 7 is elastically slidably mounted on the separation box 1, with one end of the pulverizing shaft 7 abutting against the surface of the rotating shaft 2. The surface of the pulverizing shaft 7 is arrayed with multiple driving protrusions 21, and the pulverizing shaft 7 is positioned along the movement trajectory of these protrusions. Thus, when the rotating shaft 2 rotates, it drives the driving protrusions 21, which intermittently abut against the pulverizing shaft 7 during rotation. This causes the pulverizing shaft 7 to drive the pulverizing blades 8 to intermittently pulverize the waste, thereby improving the pulverizing effect and ensuring complete removal of kitchen waste.

[0047] like Figure 2 As shown, in another preferred embodiment of the present invention, the crushing shaft 7 can be elastically mounted on the separation box 1 by means of a third elastic element. Specifically, the two ends of the third elastic element are respectively fixedly mounted on the crushing shaft 7 on the separation box 1.

[0048] like Figure 2 and Figure 3As shown, in another preferred embodiment of the present invention, in order to lock the state of the crushing blade 8 so that the crushing blade 8 can always be in the processing chamber, a position locking mechanism is also provided between the separation box 1 and the crushing shaft 7. The position locking mechanism includes a plurality of locking rods 24 arranged in an array on the outside of the crushing shaft 7. The locking rods 24 are elastically slidably disposed on the crushing shaft 7. The end of the locking rod 24 away from the crushing shaft 7 is disposed in a locking groove 26 on the mounting base 28. The mounting base 28 is fixedly installed on the separation box 1. There are a plurality of locking grooves 26, which are arranged in a circumferential array on the outside of the crushing shaft 7. Thus, when the crushing shaft 7 is locked in position by the locking grooves 26 during rotation, but needs to change position, the crushing shaft 7 rotates to overcome the resistance between the locking rods 24 and the locking grooves 26, and rotates to change position. After the position change is completed, the locking rods 24 are inserted into another locking groove 26 to lock.

[0049] like Figure 5 and Figure 6 As shown, in another preferred embodiment of the present invention, the locking rod 24 is slidably disposed in the sliding cavity 27 on the crushing shaft 7, and the bottom of the locking rod 24 is elastically slidably disposed in the sliding cavity 27 by a second elastic member 25. This achieves an elastic sliding arrangement. There can be two locking rods 24, and there can be four locking grooves 26. The second elastic member 25 can be a helical spring.

[0050] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, in another preferred embodiment of the present invention, the intermediate filter sleeve 4 includes a support sleeve and a filter screen sleeved on the outside of the support sleeve, and the support sleeve is rotatably mounted on the bottom of the separation tank 1. This facilitates the filtration of liquid from the filter residue inside the separation tank 1.

[0051] A discharge block 16 is elastically slidably disposed at the bottom of the support sleeve. The discharge block 16 is used to reciprocate inside the support sleeve to change the internal air pressure of the intermediate filter sleeve 4, thereby accelerating the filtration of liquid. The intermediate filter sleeve 4 is elastically rotatably mounted on the separation box 1 by a torsion spring.

[0052] like Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, in another preferred embodiment of the present invention, the discharge block 16 is provided with a connecting hole 17, and the support sleeve is provided with a liquid discharge port 29, which is used to communicate with the connecting hole 17. Drive rods 18 are provided on both sides of the discharge block 16, and the drive rods 18 abut against the inner wall of the drive ring 19 installed at the bottom of the separation box 1. The drive ring 19 is used to change the position of the discharge block 16 when the intermediate filter sleeve 4 rotates with it. The drive ring 19 is eccentrically positioned relative to the rotation center of the filter sleeve 4. Thus, as the intermediate filter sleeve 4 rotates, the discharge block 16 slides reciprocally inside the intermediate filter sleeve 4 under the action of elasticity, drive rod 18, and drive ring 19. When the discharge block 16 moves away from the filter sleeve 4, it can draw in the liquid accumulated on the intermediate filter sleeve 4, and then discharge the collected liquid through the liquid discharge port 29 and the connecting hole 17, thereby improving the efficiency of liquid filtration. When the intermediate filter sleeve 4 returns to the vertical state, the discharge block 16 returns to its initial state. The liquid discharge port 29 is located near the groove 5 to facilitate liquid discharge when tilted. Figure 8 An isolation sleeve is provided on the outside of the support sleeve shown. The isolation sleeve is connected to the bottom of the separation box 1 to isolate the bottom of the separation box 1 and the area below it.

[0053] A third elastic element is provided between the discharge block 16 and the support sleeve. The two ends of the third elastic element are fixedly installed on the intermediate filter sleeve 4 and the discharge block 16, respectively, thus achieving an elastic installation between the intermediate filter sleeve 4 and the discharge block 16. The third elastic element is a helical spring. The discharge block 16 is provided with a one-way port for venting gas during the compression process inside the filter sleeve 4. This allows air to escape during the compression process of the discharge block 16 inside the filter sleeve 4, thereby preventing liquid on the filter sleeve 4 from being trapped in the kitchen waste.

[0054] The partition 3 is elastically mounted on the rotating shaft 2 via a first elastic element 6, with both ends of the first elastic element 6 fixedly mounted on the partition 3 and the rotating shaft 2, respectively. This achieves the elastic mounting of the partition 3.

[0055] like Figure 1 and Figure 2 As shown, in another preferred embodiment of the present invention, in order to drive the rotating shaft 2 to rotate, a power mechanism is also provided on the separation box 1. The power mechanism includes a drive motor 11 fixedly installed on the separation box 1. A second gear 10 is provided at the output end of the drive motor 11. The second gear 10 meshes with a first gear 9. The first gear 9 is sleeved on the rotating shaft 2.

[0056] The bottom of the separation box 1 is also provided with a liquid receiving chamber 20, which is used to receive the liquid passing through the bottom of the separation box 1. The lower end of the intermediate filter sleeve 4 is located in the liquid receiving chamber 20, and the intermediate filter sleeve 4 passes through the lower end of the separation box 1 and is connected by soft rubber, which facilitates the rotation of the intermediate filter sleeve 4.

[0057] The liquid passage structure consists of a passage hole on the bottom plate of the separation tank 1, and a filter screen is laid on the bottom plate, which effectively enables the liquid to pass through.

[0058] In another preferred embodiment of the present invention, the intermediate filter sleeve 4 can also be connected to a rotating motor. The rotating motor is used to drive the intermediate filter sleeve 4 to deflect into the groove 5 when the partition 3 passes by, and then the intermediate filter sleeve 4 rotates in the opposite direction to return to its initial state when the partition 3 leaves. This achieves the rotation of the intermediate filter sleeve 4.

[0059] The working principle of this invention is:

[0060] The crushing chamber 14 crushes the kitchen waste, and then the liquid enters the separation chamber 1. The drive motor 11 is energized, driving the rotating shaft 2 to rotate through the second gear 10 and the first gear 9. Due to the eccentric setting of the rotating shaft 2, the kitchen waste entering the separation chamber 1 first enters the processing chamber when it is in its largest space. As the rotating shaft 2 rotates, the processing chamber gradually shrinks with the change of position, thus pressing and filtering the kitchen waste. The liquid is discharged through the liquid passage structure at the bottom of the separation chamber 1. During the processing, when the intermediate filter sleeve 4 passes through, the intermediate filter sleeve 4 can also filter out the liquid in the kitchen waste in the middle position of the processing chamber. When the partition 3 comes into contact with the intermediate filter sleeve 4, the intermediate filter sleeve 4 deflects and enters the groove 5, allowing the partition 3 to pass through. When the partition 3 leaves the intermediate filter sleeve 4, the intermediate filter sleeve 4 returns to the vertical position under the action of elasticity, and then filters out the liquid in the kitchen waste in the middle position of the next processing chamber. The intermediate filter sleeve 4 deflects... During the process, the drive rod 18 on the discharge block 16, under the action of the drive ring 19 and elasticity, causes the discharge block 16 to slide back and forth inside the intermediate filter sleeve 4, thereby periodically creating a negative pressure inside the intermediate filter sleeve 4, thus accelerating the liquid separation. When the processing chamber moves to the minimum space state, it completes the filtration of kitchen waste, and then passes through the discharge port 12. The crushing component in the discharge port 12 crushes the compressed kitchen waste, allowing the kitchen waste to be completely discharged through the discharge port 12, preventing the kitchen waste from re-entering the rotating shaft 2 for repeated pressing and filtration. During the crushing process, when the partition 3 approaches the crushing blade 8, the rack 23 meshes with the gear 22, causing the crushing blade 8 to rotate as the partition 3 passes by, thus preventing the partition 3 from colliding with the crushing blade 8. The rotation of the rotating shaft 2 drives the drive protrusion 21, which intermittently abuts the crushing shaft 7 during the rotation of multiple drive protrusions 21, thereby causing the crushing shaft 7 to drive the crushing blade 8 to crush intermittently, thus improving the crushing effect.
