Technical Field
[0001] This utility model relates to the field of filter technology, specifically to centrifugal filters. Background Technology
[0002] A centrifugal filter is a common device that uses centrifugal force to achieve solid-liquid separation. Its basic principle is that a rotating component equipped with a filter screen, driven by a motor, rotates at high speed within a sealed cylinder. As the mixture to be treated rotates, the solid particles are thrown towards and trapped by the filter screen under the immense centrifugal force, while the clarified liquid passes through, thus achieving separation. In the production process of ginseng craft beer, centrifugal filtration is a crucial step in the post-processing of the extract, used to remove suspended particles, cell debris, and other impurities remaining in the liquid after extraction, laying the foundation for subsequent membrane filtration and product bottling.
[0003] Traditional centrifugal filter cartridges are typically fixed directly to a rotating frame using only multiple circumferentially distributed bolts. During installation, operators not only need to laboriously align the heavy cartridges but also must overcome the pre-tightening force of the bolts within a confined space to ensure all bolt holes are aligned, making operation extremely inconvenient. Furthermore, after processing, cleaning the centrifugal filter cylinder often requires manual hand-held water jet rinsing, which is time-consuming and labor-intensive, resulting in a heavy workload for workers. Therefore, those skilled in the art provide a centrifugal filter to solve the problems mentioned in the background section. Summary of the Invention
[0004] The purpose of this invention is to provide a centrifugal filter that solves the problems mentioned in the background section of the prior art.
[0005] This utility model provides the following technical solution: a centrifugal filter, including a protective cylinder, a motor fixedly connected to the lower end of the cylinder, a mounting bracket rotatably connected to the bottom of the inner wall of the cylinder, the output end of the motor passing through the cylinder and fixedly connected to the middle of the lower end of the mounting bracket, a protective cover fixedly connected to the upper end of the cylinder by bolts, a processing component for filtration installed inside the mounting bracket, and a cleaning component for rinsing the inner wall of the cylinder installed near the upper part of the inner wall of the cylinder.
[0006] As a preferred embodiment of the above technical solution, the processing component includes a fixing frame, which is fixedly connected to the mounting frame by bolts. A filter screen is fixedly connected to the inner wall of the fixing frame, and two symmetrically arranged sliding cavities are opened at the upper part of the mounting frame.
[0007] As a preferred embodiment of the above technical solution, a set of springs is fixedly connected to the inner walls of both sliding cavities, and a movable plate is slidably connected to both sliding cavities. The two movable plates are respectively fixedly connected to one end of the two sets of springs, and a wedge block is fixedly connected to one side of each of the two movable plates. The two wedge blocks are symmetrically arranged, and the two wedge blocks pass through the two sliding cavities respectively, and the two wedge blocks are slidably arranged inside the mounting frame.
[0008] As a preferred embodiment of the above technical solution, each of the two sliding cavities has a movable opening at its top, and each of the two movable openings has a sliding connecting rod. The two connecting rods are respectively slidably connected to the upper ends of the two movable plates, and each of the two connecting rods has a threaded rod threadedly connected to its inner end. Each of the two threaded rods has a rotating block fixedly connected to its upper end.
[0009] As a preferred embodiment of the above technical solution, the cleaning component includes a fixing ring, which is fixedly connected to the upper part of the inner wall of the cylinder and rotatably sleeved on the upper part of the outer wall of the mounting frame. An annular pipe is fixedly connected to the lower end of the fixing ring, and multiple nozzles are fixedly installed on the outside of the annular pipe. A water supply pipe passes through the upper end of the cylinder, and the output end of the water supply pipe is connected to the annular pipe.
[0010] As a preferred embodiment of the above technical solution, the upper end of the protective cover is connected to an injection pipe, the lower end of the cylinder is connected to a drain pipe, a solenoid valve is installed inside the drain pipe, a support seat is fixedly fitted on the lower part of the outer side of the cylinder, multiple limiting grooves are opened on the inner wall of the mounting frame, multiple limiting blocks are fixedly connected to the outside of the fixed frame, and the multiple limiting blocks are respectively matched with the multiple limiting grooves. Both the outer wall of the fixed frame and the inner wall of the mounting frame are provided with sealing gaskets.
[0011] Compared with the prior art, the beneficial effects of this utility model are: When the mounting bracket is inserted into the installation frame, the two symmetrical wedge-shaped blocks are compressed and retract into the sliding cavity. After the mounting bracket is in place, the wedge-shaped blocks pop out and are positioned on top of the mounting bracket under the restoring force of the spring. The wedge-shaped blocks press and limit the mounting bracket, thus achieving pre-fixation of the mounting bracket. This allows for easy alignment of the subsequent bolt holes, greatly simplifying the filter installation process and improving installation efficiency. Furthermore, through the annularly arranged nozzles, the cleaning fluid can evenly cover the entire inner wall of the cylinder, significantly improving cleaning efficiency and effect while greatly reducing the labor intensity of manual cleaning.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] Please see Figures 1-5 The present invention provides a technical solution: a centrifugal filter, including a protective cylinder 1, a motor 2 fixedly connected to the lower end of the cylinder 1, a mounting bracket 3 rotatably connected to the bottom of the inner wall of the cylinder 1, the output end of the motor 2 passing through the cylinder 1 and fixedly connected to the middle of the lower end of the mounting bracket 3, a protective cover 4 fixedly connected to the upper end of the cylinder 1 by bolts, a processing component 5 for filtration installed inside the mounting bracket 3, and a cleaning component 6 for rinsing the inner wall of the cylinder 1 installed near the upper part of the inner wall of the cylinder 1.
[0016] Furthermore, the motor 2 drives the mounting bracket 3 and the processing component 5 inside the mounting bracket 3 to rotate at high speed inside the cylinder 1, using centrifugal force to achieve liquid-solid separation. The protective cover 4 provides sealing protection and facilitates maintenance, while the independent cleaning component 6 can automatically flush the inner wall of the stationary cylinder 1. Together, they form a compact, efficient, and easy-to-clean device.
[0017] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the processing component 5 includes a fixing frame 501, which is fixedly connected to the mounting frame 3 by bolts. A filter screen 502 is fixedly connected to the inner wall of the fixing frame 501. Two symmetrically arranged sliding cavities 503 are opened at the upper part of the interior of the mounting frame 3.
[0018] Furthermore, the fixing frame 501 serves as the core carrier to fix the filter screen 502, and the fixing frame 501 is secured within the rotating mounting frame 3 by bolts, thereby achieving high-speed centrifugal filtration. The fixing frame 501 ensures the installation rigidity and stability of the filter screen 502, while the symmetrically arranged sliding cavities 503 on the mounting frame 3 provide space for subsequent mechanisms, together laying the foundation for the convenient installation and reliable operation of the filter screen 502.
[0019] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, a set of springs 504 are fixedly connected to the inner walls of both sliding cavities 503. A movable plate 505 is slidably connected to both sliding cavities 503. The two movable plates 505 are fixedly connected to one end of the two sets of springs 504 respectively. A wedge block 506 is fixedly connected to one side of each of the two movable plates 505. The two wedge blocks 506 are symmetrically arranged and pass through the two sliding cavities 503 respectively. The two wedge blocks 506 are slidably arranged inside the mounting bracket 3.
[0020] Furthermore, during the lowering of the fixing frame 501, the edge of the fixing frame 501 contacts and presses against the inclined surfaces of the two symmetrical wedge blocks 506. Under the action of the inclined surfaces, the wedge blocks 506 overcome the elastic force of the spring 504 and retract into the sliding cavity 503. When the fixing frame 501 is in place, the wedge blocks 506 move precisely to the upper flange of the fixing frame 501. The restoring force of the spring 504 pushes the moving plate 505 and the wedge blocks 506 to pop out, pressing the fixing frame 501 from above. This pre-compression force makes the fixing frame 501 fit tightly against the interior of the mounting bracket 3, ensuring the sealing gasket layer is airtight. At the same time, it automatically aligns the bolt holes on the fixing frame 501 with the screw holes on the mounting bracket 3. The operator then only needs to easily tighten the bolts to complete the fixing of the fixing frame 501, greatly simplifying the installation process.
[0021] As one implementation method in this embodiment, please refer to Figure 4 As shown, each of the two sliding cavities 503 has a movable opening 507 at the top of its inner wall. Each of the two movable openings 507 is slidably connected to a toggle rod 508. The two toggle rods 508 are slidably connected to the upper ends of the two movable plates 505 respectively. Each of the two toggle rods 508 is threadedly connected to a threaded rod 509. Each of the two threaded rods 509 is fixedly connected to a rotating block 510 at its upper end.
[0022] Furthermore, when the filter screen 502 needs to be disassembled for cleaning, the user pushes the rotating block 510, causing the wedge block 506 to retract into the sliding cavity 503. Then, the user rotates the rotating block 510, causing the threaded rod 509 to rotate. Since the threaded rod 509 and the actuating rod 508 are internally threaded, the threaded rod 509 will move downward, driving the rotating block 510 downward until the lower end of the rotating block 510 contacts the top of the mounting bracket 3, thereby achieving frictional fixation of the rotating block 510. This prevents the wedge block 506 from resetting and avoids the wedge block 506 blocking when the fixing bracket 501 is lifted. At this time, the bolts fixing the fixing bracket 501 can be removed, and the fixing bracket 501 can be lifted, thereby pulling the filter screen 502 out of the cylinder 1 for cleaning. While ensuring operational stability, maintenance efficiency is significantly improved.
[0023] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the cleaning component 6 includes a retaining ring 601, which is fixedly connected to the upper part of the inner wall of the cylinder 1. The retaining ring 601 is rotatably sleeved on the upper part of the outer wall of the mounting bracket 3. An annular tube 602 is fixedly connected to the lower end of the retaining ring 601. Multiple nozzles 603 are fixedly installed on the outside of the annular tube 602. A water supply pipe 604 passes through the upper end of the cylinder 1, and the output end of the water supply pipe 604 is connected to the annular tube 602.
[0024] Furthermore, during the cleaning of the device, the cleaning fluid is pumped into the stationary annular pipe 602 through the water supply pipe 604. The cleaning fluid is sprayed out from multiple nozzles 603 distributed circumferentially below the annular pipe 602, forming an umbrella-shaped water curtain. These nozzles 603 are inclined towards the inner wall of the cylinder 1, thereby realizing automatic rinsing of the inside of the cylinder 1, which significantly improves the cleaning efficiency and effect, while greatly reducing the labor intensity of manual cleaning. In addition, the fixing ring 601 can support the upper part of the mounting frame 3, thereby ensuring the stability of the mounting frame 3 when it rotates.
[0025] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the upper end of the protective cover 4 is connected to the injection pipe 7, the lower end of the cylinder 1 is connected to the drain pipe 8, the drain pipe 8 is installed with a solenoid valve 9, the lower part of the cylinder 1 is fixedly fitted with a support base 10, the inner wall of the mounting frame 3 is provided with multiple limiting grooves 11, the outer side of the fixing frame 501 is fixedly connected with multiple limiting blocks 12, the multiple limiting blocks 12 are respectively matched with the multiple limiting grooves 11, and the outer wall of the fixing frame 501 and the inner wall of the mounting frame 3 are both provided with sealing gaskets.
[0026] Furthermore, the material to be filtered enters the cylinder 1 through the injection pipe 7, and the falling material falls into the fixed frame 501. The separated liquid is discharged by the drain pipe 8 and the solenoid valve 9. The support seat 10 provides stable support for the cylinder 1. The guide structure of the limiting block 12 and the limiting groove 11, together with the sealing gasket, greatly simplifies the installation and positioning process of the fixed frame 501 and ensures the sealing of the operation, thereby improving the ease of operation and reliability of the entire equipment.
[0027] Working principle: When installing the filter screen 502, open the protective cover 4 and lower the fixing frame 501 containing the filter screen 502 along the inner wall of the mounting frame 3. At this time, the limiting block 12 on the outer side of the fixing frame 501 will slide down along the limiting groove 11 on the inner wall of the mounting frame 3, which plays a guiding and circumferential positioning role, preventing the fixing frame 501 from rotating inside the mounting frame 3. During the lowering process, the edge of the fixing frame 501 will contact and press the inclined surfaces of the two symmetrical wedge blocks 506. Under the action of the inclined surfaces, the wedge blocks 506 overcome the elastic force of the spring 504 and retract into the sliding cavity 503. When the fixing frame 501 is placed in place, the wedge blocks 506 just move to the upper flange of the fixing frame 501. The restoring force of the spring 504 pushes the moving plate 505 and the wedge blocks 506 to pop out, pressing the fixing frame 501 from above. This pre-compression force makes the fixing frame 501 fit tightly with the inside of the mounting frame 3, ensuring the sealing gasket layer is airtight, and at the same time, the fixing frame 501... The bolt holes automatically align with the screw holes on the mounting bracket 3. The operator then only needs to easily tighten the bolts to complete the double fixation of the fixing bracket 501, which greatly simplifies the filter screen installation process and improves installation efficiency. When the filter screen 502 needs to be removed for cleaning, the user pushes the rotating block 510, causing the wedge block 506 to retract into the sliding cavity 503. Then, the user rotates the rotating block 510, causing the threaded rod 509 to rotate. Since the threaded rod 509 and the actuating rod 508 are internally threaded, the threaded rod 509 will move downward, driving the rotating block 510 downward until the lower end of the rotating block 510 contacts the top of the mounting bracket 3, thereby achieving friction fixation of the rotating block 510 and preventing the wedge block 506 from resetting. At this time, the bolts fixing the fixing bracket 501 can be removed, and the fixing bracket 501 can be lifted to pull the filter screen 502 out of the cylinder 1 for cleaning. While ensuring operational stability, maintenance efficiency is significantly improved. When cleaning the device, the cleaning fluid is pumped into the stationary annular pipe 602 through the water supply pipe 604. The cleaning fluid is sprayed out from multiple nozzles 603 distributed circumferentially below the annular pipe 602 to form an umbrella-shaped water curtain. These nozzles 603 are inclined towards the inner wall of the cylinder 1, thereby realizing automatic rinsing of the inside of the cylinder 1, which significantly improves the cleaning efficiency and effect, while greatly reducing the labor intensity of manual cleaning.
