[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This utility model provides a recovery device for a filter press, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a receiving mechanism 1 and a discharging mechanism 2.

[0024] The top of the receiving mechanism 1 is open.

[0025] The discharge mechanism 2 includes a push plate 21 and a drive assembly 3. The push plate 21 is slidably connected to the receiving mechanism 1. The receiving mechanism 1 has a discharge port 12 on one side. The fixed end of the drive assembly 3 is connected to the receiving mechanism 1, and the movable end of the drive assembly 3 is connected to the push plate 21. The drive assembly 3 is used to drive the push plate 21 to slide so as to push the slag out of the discharge port 12.

[0026] During operation, the filter press residue falls into the top-opening receiving mechanism 1. When the residue needs to be discharged for bagging, the drive assembly 3 is activated. The movable end of the drive assembly 3 moves, causing the push plate 21 connected to it to slide within the receiving mechanism 1. Because the push plate 21 is in contact with and can slide against the inner wall of the receiving mechanism 1, the residue in the receiving mechanism 1 is gradually pushed towards the discharge port 12 during the movement of the push plate 21, until the residue is pushed out of the discharge port 12.

[0027] In this invention, the material residue is pushed out of the discharge port 12 by the sliding of the push plate 21 in the receiving mechanism 1, which effectively overcomes the stickiness of the material residue, allows the material residue to be discharged smoothly, and improves the processing efficiency.

[0028] To drive the pusher plate 21 to slide back and forth, please refer to... Figure 1 In a preferred embodiment, the drive assembly 3 includes a cylinder 31, which is mounted on the receiving mechanism 1, and the piston rod of the cylinder 31 is connected to the push plate 21.

[0029] When in use, when the piston rod of cylinder 31 extends, push plate 21 moves and pushes the slag out of discharge port 12; when the piston rod of cylinder 31 retracts, push plate 21 resets.

[0030] To control the opening and closing of the discharge gate 22, please refer to... Figure 2 In a preferred embodiment, the discharge mechanism 2 further includes a discharge gate 22 and an opening and closing component 4. The discharge gate 22 is rotatably connected to the receiving mechanism 1 on one side. The discharge gate 22 is located at the discharge port 12. The opening and closing component 4 is used to control the opening and closing of the discharge gate 22.

[0031] During use, the opening and closing of the discharge gate 22 and the action of the push plate 21 work together during the discharge process. When discharge is required, the discharge gate 22 is first opened by the opening and closing component 4, and then the drive component 3 drives the push plate 21 to slide in the receiving mechanism 1, pushing the slag out of the discharge port 12; after the discharge is completed, the push plate 21 is reset, and the discharge gate 22 is closed by the opening and closing component 4 to prepare for the next receiving and discharge.

[0032] To ensure that cylinder 31 synchronously controls the opening and closing of discharge gate 22, please refer to... Figure 2 In a preferred embodiment, the opening and closing assembly 4 includes a connecting rod 41 and a slider 42. One end of the connecting rod 41 is hinged to the push plate 21, and the other end of the connecting rod 41 is hinged to the slider 42. The slider 42 is slidably connected to the discharge gate 22 along the length direction of the discharge gate 22.

[0033] In operation, when the piston rod of cylinder 31 pushes the push plate 21 towards the discharge port 12, one end of the connecting rod 41, which is hinged to the push plate 21, moves forward synchronously. The connecting rod 41, under the pulling force of the push plate 21, tilts and rotates. Since the other end of the connecting rod 41 is hinged to the slider 42, its tilt angle changes, causing the slider 42 to slide within the groove of the discharge gate 22. As the slider 42 slides along the length of the discharge gate 22, it applies a horizontal thrust to the discharge gate 22 through the hinge point. Because one side of the discharge gate 22 is fixed to the receiving mechanism 1, forming a pivot point, this horizontal thrust is decomposed into a component perpendicular to the discharge gate 22, thereby pushing the discharge gate 22 to rotate and open around the pivot point. When the push plate 21 reaches the end of its stroke and the slag is about to be discharged, the discharge gate 22 also rotates to its maximum opening angle under the linkage of the slider 42 and the connecting rod 41, ensuring that the discharge port 12 is fully open and the slag is discharged smoothly.

[0034] After the slag is discharged, the piston rod of cylinder 31 retracts, causing push plate 21 to move in the opposite direction. During the return stroke of push plate 21, connecting rod 41 tilts and rotates in the opposite direction, pulling slider 42 to slide in the opposite direction along the groove of discharge gate 22. As slider 42 slides in the opposite direction, it applies a reverse horizontal pulling force to discharge gate 22, causing it to rotate in the opposite direction around the hinge point until it returns to the closed state, fitting snugly against discharge port 12, preventing slag leakage or external impurities from entering receiving mechanism 1. The opening and closing of discharge gate 22 is synchronously controlled by the driving force of push plate 21, eliminating the need for separate motors, cylinders 31, and other driving devices, simplifying the structure and reducing energy consumption.

[0035] To reduce the possibility of damage to connecting rod 41 and slider 42, please refer to Figure 1 In a preferred embodiment, the opening and closing assembly 4 further includes a protective cover 43, which is connected to the push plate 21 and is sleeved on the outside of the connecting rod 41 and the slider 42.

[0036] During use, the protective cover 43's sealing design can isolate external impurities, keep the inside of the component clean, reduce jamming and jamming caused by impurities, ensure that the connecting rod 41 and the slider 42 always maintain smooth transmission performance, extend the service life of the component, and ensure the stable opening and closing of the discharge gate 22.

[0037] To improve the cleanliness of the receiving mechanism 1, please refer to... Figure 1 In a preferred embodiment, the receiving mechanism 1 further includes a sealing layer 13, which is made of rubber and has a thickness of 1 mm. The sealing layer 13 is connected to the periphery of the push plate 21 and abuts against the inner wall of the receiving mechanism 1.

[0038] During use, as the push plate 21 slides back and forth within the receiving mechanism 1, a tiny gap exists between its periphery and the inner wall of the receiving mechanism 1. The sealing layer 13, made of elastic material, tightly adheres to the inner wall, forming a dynamic sealing barrier that prevents sticky residue or residual waste liquid from overflowing from the gap, thus avoiding contamination of the external environment of the equipment or corrosion of the structure of the receiving mechanism 1.

[0039] To reduce the possibility of material residue adhering to the inner wall of the receiving mechanism 1, please refer to... Figure 1 In a preferred embodiment, the receiving mechanism 1 further includes an anti-stick layer made of polytetrafluoroethylene with a thickness of 0.1 mm, and the anti-stick layer is connected to the inner side of the receiving mechanism 1.

[0040] During use, the residue from the filter press is often sticky due to residual waste liquid, easily adhering to the inner wall of the receiving mechanism 1. The anti-sticking layer significantly reduces the adhesion between the residue and the inner wall of the receiving mechanism 1. The residue is less likely to adhere inside the receiving mechanism 1 and is more easily pushed out by the pusher plate 21, effectively reducing residue residue on the inner wall of the box and preventing residue accumulation from affecting subsequent receiving.

[0041] To ensure the material and slag are spread more evenly within the receiving mechanism 1, please refer to... Figure 1 In a preferred embodiment, the receiving mechanism 1 further includes a vibration component 5, which is disposed on the receiving mechanism 1 and is used to drive the receiving mechanism 1 to vibrate so that the material residue is evenly spread inside the receiving mechanism 1.

[0042] During use, uneven accumulation of slag can easily occur during the unloading process of the filter press, resulting in some areas being too thick and others too thin. When the vibration component 5 is working, it causes the receiving mechanism 1 to shake regularly through high-frequency vibration, which redistributes the slag within the box and spreads it evenly. This not only makes full use of the space of the receiving mechanism 1, but also provides stable force conditions for the subsequent discharge of the push plate 21, preventing the push plate 21 from being obstructed by excessive local slag accumulation.

[0043] To drive the material receiving mechanism 1 to vibrate, please refer to... Figure 1 In a preferred embodiment, the vibration assembly 5 includes a vibration motor 51, which is mounted on the receiving mechanism 1.

[0044] During use, the material residue in the receiving mechanism 1 can be spread quickly and evenly through the precise control of the vibration motor 51, creating favorable conditions for the subsequent discharge of material by the push plate 21, and significantly improving the overall efficiency and reliability of the filter press recovery device.

[0045] To reduce the energy consumption of the vibration motor 51, please refer to... Figure 1 In a preferred embodiment, the vibration assembly 5 further includes a support 52 and a spring 53. The receiving mechanism 1 is disposed on the support 52, one end of the spring 53 is connected to the receiving mechanism 1, and the other end of the spring 53 is connected to the support 52.

[0046] In use, on the one hand, the elastic potential energy stored in the spring 53 during vibration can assist the motor in doing work. When the receiving mechanism 1 vibrates downward, the spring 53 compresses to store energy, and releases energy when vibrating upward, thus reducing energy consumption. On the other hand, the flexible connection between the receiving mechanism 1 and the support 52 reduces the possibility of damage to the receiving mechanism 1.

[0047] To better understand this utility model, the following is combined with... Figure 1 - Figure 2The working principle of a recycling device for a filter press according to the present invention is described in detail: The filter press residue falls into a receiving mechanism 1 with an open top. When the residue needs to be discharged for bagging, the drive assembly 3 is activated. The movable end of the drive assembly 3 moves, causing the push plate 21 connected to it to slide within the receiving mechanism 1. Because the push plate 21 is in contact with and can slide against the inner wall of the receiving mechanism 1, during the movement of the push plate 21, it gradually pushes the residue in the receiving mechanism 1 towards the discharge port 12 until the residue is discharged from the discharge port 12.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
