Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a hydraulic cylinder driven filter press. Background Technology

[0002] A hydraulic cylinder-driven filter press is a device that uses a hydraulic system to apply pressure through a cylinder to press filter plates together, thereby achieving solid-liquid separation. It is widely used in industries such as wastewater treatment, chemical industry, and food industry. By pressing the filter plates tightly together under high pressure, it accelerates the discharge of filtrate and improves dewatering efficiency. The hydraulic drive gives it a high degree of automation, enabling it to efficiently and stably process suspensions of various concentrations. It is also simple to maintain and highly adaptable.

[0003] In practical applications of existing technologies, materials may adhere excessively between filter plates during the filter press process, making discharge difficult and requiring manual intervention to remove the materials. This not only increases the complexity of the operation but also results in a significant waste of time. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the aforementioned problems in the prior art, this utility model provides a hydraulic cylinder-driven filter press, which solves the problem that in practical applications, materials may adhere excessively between the filter plates during the filtration process, leading to difficulties in discharge and requiring manual intervention to remove the materials. This phenomenon not only increases the complexity of operation but also causes a significant waste of time.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solution adopted by this utility model is as follows:

[0008] A hydraulically driven filter press includes a support frame, a fixed frame fixedly connected to the support frame, a filter press body installed inside the fixed frame, a plurality of swaying devices for assisting material feeding installed on the filter press body, a blocking device for increasing resistance to the swaying devices fixedly connected to the filter press body, a funnel installed inside the support frame, and two symmetrically arranged material feeding devices for clearing the funnel inside the funnel.

[0009] The shaking device includes a fixed plate with a storage slot inside. A connecting plate is installed inside the storage slot. A connecting rod is fixedly connected to the connecting plate and the storage slot. A rotating plate is rotatably connected to the connecting rod. Two coil springs are sleeved on the connecting rod.

[0010] One end of each of the two coil springs is fixedly connected to the rotating plate, one end of one coil spring is fixedly connected to the storage slot, and one end of the other coil spring is fixedly connected to the connecting plate.

[0011] The cross-section of the rotating plate is set to an ellipse to facilitate rotation within the storage slot.

[0012] The blocking device includes a mounting plate, which is fixedly connected to a fixing frame, and several baffles are fixedly connected under the mounting plate.

[0013] The baffle overlaps one side of the rotating plate.

[0014] The feeding device includes a drive motor, which is fixedly connected to the funnel. A rotating rod is fixedly connected to the output end of the drive motor. A rectangular plate is fixedly connected to one end of the rotating rod. The rectangular plate is fixedly connected to the funnel. An elastic rod is fixedly connected to the outside of the rotating rod. A scraper is fixedly connected to one end of the elastic rod.

[0015] The cross-section of the scraper is set as a triangle.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this utility model are as follows: After the material processing is completed, during the unfolding process of the filter press body, the fixed plate moves synchronously. At this time, the rotating plate applies a pushing force to the baffle, causing the baffle to drive the rotating plate to rotate freely through the connecting rod. The rotating plate then applies an external force to the fixed plate, causing the fixed plate to drive the filter plates inside the filter press to shake synchronously. During the shaking process, the material can fall off and be discharged smoothly. In the pressing stage, the baffle applies a pushing force to the rotating plate, causing the rotating plate to rotate freely. When the rotating plate moves away from the baffle, the coil spring provides elastic force, causing the rotating plate to rotate freely along the connecting rod and quickly reset. When the material is discharged, the drive motor drives the rotating rod to rotate freely within the rectangular plate. The rotating rod further drives the elastic rod and scraper to move synchronously. The elastic rod ensures that the scraper always keeps in contact with the surface of the funnel, thereby smoothly discharging the material from the funnel and completing the process of material feeding and smooth discharge.

Detailed Implementation

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4 As shown, the present invention discloses a hydraulic cylinder driven filter press, including a support frame 1, a fixed frame 2 fixedly connected to the support frame 1, a filter press body 3 installed inside the fixed frame 2, a plurality of swaying devices 4 for assisting material feeding installed on the filter press body 3, a blocking device 5 for increasing resistance to the swaying devices 4 fixedly connected to the filter press body 3, a funnel 6 installed inside the support frame 1, and two feeding devices 7 for unblocking the funnel 6 symmetrically arranged inside the funnel 6. In actual implementation, after the material processing is completed, the filter press body 3 unfolds while the fixed plate 41 moves synchronously. At this time, the rotating plate 45 applies a pushing force to the baffle 52, causing the baffle 52 to drive the rotating plate 45 to rotate freely through the connecting rod 44. The rotating plate 45 then applies an external force to the fixed plate 41, causing the fixed plate 41 to drive the filter plates inside the filter press to shake synchronously. During the shaking process, the material can fall off and be discharged smoothly. In the pressing stage, the baffle 52 applies a pushing force to the rotating plate 45, causing the rotating plate 45 to rotate freely. When the rotating plate 45 moves away from the baffle 52, the coil spring 46 provides elasticity, causing the rotating plate 45 to rotate freely along the connecting rod 44 and quickly reset, thereby completing the material feeding.

[0026] Optionally, the shaking device 4 includes a fixed plate 41, with a storage slot 42 inside the fixed plate 41. A connecting plate 43 is installed inside the storage slot 42, and a connecting rod 44 is fixedly connected to the connecting plate 43 and the storage slot 42. A rotating plate 45 is rotatably connected to the connecting rod 44, and two coil springs 46 are sleeved on the connecting rod 44. In actual implementation, the cooperation between the storage slot 42 and the connecting plate 43 provides a stable support structure for the shaking device 4. The storage slot 42 provides a fixed installation position for the connecting plate 43, while the connecting plate 43 enhances the stability of the connecting rod 44, preventing displacement during shaking. This structural design ensures smooth rotation of the rotating plate 45 and improves the durability of the shaking device 4, allowing it to maintain good working condition even after long-term use.

[0027] Optionally, one end of each of the two coil springs 46 is fixedly connected to the rotating plate 45. One end of one coil spring 46 is fixedly connected to the storage groove 42, and the other end of the other coil spring 46 is fixedly connected to the connecting plate 43. In actual implementation, the cooperation between the connecting rod 44 and the coil spring 46 ensures that the rotating plate 45 has good reset capability during shaking. The connecting rod 44, as a support structure, provides a stable rotation axis for the rotating plate 45, while the coil spring 46, through its elastic force, quickly returns to its original position after the rotating plate 45 is pushed by an external force, avoiding any stagnation during shaking. This cooperation not only ensures the flexibility of the shaking device 4 but also improves the automated unloading efficiency of the filter press.

[0028] Optionally, the cross-section of the rotating plate 45 is set to an ellipse to facilitate rotation within the storage trough 42. In actual implementation, the cross-section of the rotating plate 45 is designed to be elliptical to facilitate smoother rotation within the storage trough 42, thereby reducing friction, improving rotation efficiency, ensuring that the shaking device 4 can work more flexibly, and enhancing the material release effect.

[0029] Optionally, the blocking device 5 includes a mounting plate 51, which is fixedly connected to the fixed frame 2. Several baffles 52 are fixedly connected to the underside of the mounting plate 51. In actual implementation, the cooperation between the baffles 52 and the rotating plate 45 enables precise control of the rotating plate 45 during pressing and unfolding. The baffles 52 apply a pushing force to the rotating plate 45, causing it to rotate or reset at the appropriate time. After being acted upon by the baffles 52, the rotating plate 45 can return to its initial position through the elastic force of the coil spring 46. This cooperation improves the sensitivity of the shaking device 4, enabling the filter press to complete the material removal process more efficiently.

[0030] Optionally, the baffle 52 overlaps one side of the rotating plate 45. In actual implementation, the baffle 52 overlapping one side of the rotating plate 45 can effectively control the movement range of the rotating plate 45, preventing it from rotating excessively or becoming uncontrollable. Through this design, the baffle 52 can apply appropriate thrust to the rotating plate 45 during the unfolding and pressing process of the filter press, ensuring that the shaking device 4 can generate appropriate force when the material falls off, thereby improving the material discharge efficiency and reducing jamming.

[0031] Optionally, the feeding device 7 includes a drive motor 71, which is fixedly connected to the funnel 6. A rotating rod 72 is fixedly connected to the output end of the drive motor 71. A rectangular plate 73 is fixedly connected to one end of the rotating rod 72, and the rectangular plate 73 is fixedly connected to the funnel 6. An elastic rod 74 is fixedly connected to the outside of the rotating rod 72, and a scraper 75 is fixedly connected to one end of the elastic rod 74. In actual implementation, when material is discharged, the drive motor 71 drives the rotating rod 72 to rotate freely within the rectangular plate 73. The rotating rod 72 further drives the elastic rod 74 and the scraper 75 to move synchronously. The elastic rod 74 ensures that the scraper 75 always remains in contact with the surface of the funnel 6, thereby smoothly discharging the material from the funnel 6.

[0032] Optionally, the cross-section of the scraper 75 is set as triangular. In actual implementation, the triangular cross-section design of the scraper 75 can effectively improve the efficiency of scraping materials, and the contact angle with the inner wall of the funnel 6 is more adapted. The triangular scraper 75 can better scrape the material accumulated at the bottom of the funnel 6, avoiding the accumulation or retention of materials, thereby ensuring the smooth discharge of materials and reducing the blockage problems that may occur during the feeding process.

All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art.
