Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a sealing device for a vacuum dehydrator. Background Technology

[0002] A disc vacuum dewatering machine is a device that uses vacuum negative pressure to achieve solid-liquid separation. Its main body consists of multiple discs mounted on a horizontal shaft, with filter plates covering the disc surfaces. During operation, a pressure difference is created on both sides of the filter plates through vacuum, causing the liquid in the slurry to pass through the filter plates and be drawn away, while the solid particles adhere to the filter plates, thus achieving dewatering. It is commonly used for material dewatering in mining, chemical and other fields. Its sealing device is crucial because a vacuum requires maintaining a negative pressure environment. If the seal is poor, outside air will seep in, destroying the vacuum level, reducing dewatering efficiency, and causing problems such as material leakage and environmental pollution. The sealing device ensures stable vacuum operation by sealing the gaps between rotating and stationary parts.

[0003] The vacuum dewatering machine is designed around the dewatering function. It mainly consists of a machine body shell, which provides installation and protection space for internal components. A horizontal main shaft runs through the machine body and is the core transmission component. Multiple sets of disc assemblies are evenly distributed on the main shaft. The surface of the assembly is covered with filter plates to trap solid particles. It is equipped with a vacuum system, including a vacuum pump, gas-liquid separator and connecting pipelines, which can create negative pressure on both sides of the filter plates. It is also equipped with a feeding device to transport the slurry to the disc area. The unloading mechanism is used to remove the dewatered solids from the filter plates.

[0004] In existing technologies, the sealing devices of some vacuum dehydrators require the sealing ring to be embedded in a deep groove between the rotating shaft and the disc hub during installation. Due to the obstruction caused by the multi-layered disc structure, the operating space is narrow and the line of sight is blocked during installation. Operators need to use long-handled tools to manually push the sealing ring in the deep groove, making it difficult to accurately align the sealing groove. Relying solely on manual feel is insufficient to ensure that the sealing ring is fully embedded in the bottom of the groove. This often results in inadequate sealing due to improper installation, ultimately leading to vacuum leakage or abnormal equipment operation. Therefore, a sealing device for vacuum dehydrators is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealing device for a vacuum dehydrator, which aims to improve the problem that the installation of the sealing ring is too difficult in some existing vacuum dehydrator sealing devices, thus causing vacuum leakage or abnormal equipment operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sealing device for a vacuum dehydrator includes a motor, a fixed plate fixedly connected to the drive end of the motor, a plurality of air guide pipes fixedly connected to the rear side of the fixed plate, an air guide shaft fixedly connected to the outer wall of the plurality of air guide pipes, a positioning mechanism installed inside the air guide shaft, and a bracket fixedly connected to the bottom end of the motor, with a quick-release mechanism installed inside the bracket.

[0008] The positioning mechanism includes a second motor. The outer wall of the second motor is fixedly connected to the inner wall of the air guide shaft. A rotating disk is fixedly connected to the drive end of the second motor. A connecting arm is rotatably connected to the outer wall of the rotating disk. A support frame is rotatably connected to the other end of the connecting arm. Two connecting blocks are slidably connected to the inner wall of the support frame. A support block is fixedly connected to the top of the two connecting blocks. A sealing ring is fixedly connected to the outer wall of the support block. An elastic component is provided inside the support frame.

[0009] Through the above technical solution: motor one can drive the fixed plate to rotate, the fixed plate drives the air guide tube to move synchronously, the air guide shaft provides the installation position for the positioning mechanism, the bracket supports motor one and the overall structure, the quick-release mechanism facilitates the quick installation and removal of the filter plate, and can realize the functions of sealing in the vacuum dehydration process and convenient replacement of the filter plate.

[0010] As a further description of the above technical solution:

[0011] The elastic component includes a damper, one end of which is fixedly connected to the outer wall of the support frame, and a spring is sleeved on the outside of the damper.

[0012] Through the above technical solution: when the support frame moves, spring 1 can undergo elastic deformation of stretching or compression, thereby generating tension or thrust on the support block, driving the support block to move synchronously. Damper 1 can slow down the movement speed of the support block, avoid it from being violently impacted by the force of the spring, ensure the smoothness of the support block's movement, and thus ensure the stable working state of the sealing ring.

[0013] As a further description of the above technical solution:

[0014] The quick-release mechanism includes a disc, the inner wall of which is fixedly connected to the outer wall of the sealing ring. Multiple filter plates are detachably connected to the outer wall of the disc. Two handles are fixedly connected to the outer wall of the filter plates. Two limiting blocks are fixedly connected to the outer wall of the filter plates. Multiple limiting blocks are fixedly connected to the inner wall of the disc. Limiting posts are fixedly connected to the inner wall of the limiting blocks. Limiting components are provided inside the limiting blocks.

[0015] Through the above technical solution: the disc is connected to the sealing ring and can move synchronously with the sealing ring; the filter plate is used for filtration; the handle is convenient for operators to hold for installation and disassembly operations; limit block one and limit block two cooperate to realize the detachable connection between the filter plate and the disc through the limit assembly; the limit post provides the action point for the limit assembly, making the installation and disassembly process of the filter plate simple and quick, and improving the efficiency of equipment maintenance.

[0016] As a further description of the above technical solution:

[0017] The limiting component includes a support column, the outer wall of which is fixedly connected to the inner wall of the limiting block one, a clamping block one fixedly connected to the outer wall of the support column, two dampers two fixedly connected to the inner wall of the limiting block one, a clamping block two fixedly connected to the other end of the damper two, a spring two sleeved on the outside of the support column, and a spring three sleeved on the outside of the damper two.

[0018] Through the above technical solution: the support column provides installation support for clamping block one. When installing the filter plate, the limiting column squeezes clamping block two, causing spring three to compress. After the limiting column enters, spring three resets and drives clamping block two to limit it on one side. At the same time, the limiting column squeezes clamping block one, causing spring two to compress. Spring two resets and pushes clamping block one to limit it on the other side, thus realizing the installation and fixation of the filter plate. The damper two can play a buffering role when clamping block two moves, ensuring a smooth clamping process. The elastic force of spring two and spring three provides clamping force for clamping block one and clamping block two, ensuring reliable limiting.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the clamping block 2 is detachably connected to the outer wall of the limiting post, the outer wall of the limiting block 1 is slidably connected to the inner wall of the limiting block 2, the outer walls of both clamping blocks 2 are slidably connected to the inner wall of the limiting block 1, and the inner wall of the clamping block 1 is slidably connected to the inner wall of the limiting block 1.

[0021] Through the above technical solution: the detachable connection between clamping block two and the limiting post realizes the clamping and releasing of the limiting post, which facilitates the installation and disassembly of the filter plate. Limiting block one slides on the inner wall of limiting block two, providing guidance for the installation and disassembly of the filter plate. Clamping block two and clamping block one slide on the inner wall of limiting block one, ensuring that they can move normally under the action of the spring to limit the limiting post, ensuring the stability of the filter plate after installation and the smoothness of disassembly.

[0022] As a further description of the above technical solution:

[0023] One end of the third spring is fixedly connected to the outer wall of the clamping block two, and the other ends of the two third springs are fixedly connected to the inner wall of the limiting block one. One end of the second spring is fixedly connected to the outer wall of the clamping block one, and the other end of the second spring is fixedly connected to the inner wall of the limiting block one.

[0024] Through the above technical solution: the two ends of spring three are respectively connected to clamping block two and limiting block one. When clamping block two is squeezed and moved, spring three is compressed and stored. After being released, it can release the elastic force to drive clamping block two to reset and clamp the limiting column. The two ends of spring two are respectively connected to clamping block one and limiting block one. When clamping block one is squeezed, spring two is compressed and stored. After being released, it releases the elastic force to push clamping block one to reset and clamp the limiting column. Thus, the elastic force of the spring can reliably limit the limiting column and ensure that the filter plate is installed firmly.

[0025] As a further description of the above technical solution:

[0026] The outer walls of the support blocks are all slidably connected to the inner walls of the air guide shaft. One end of the first spring is fixedly connected to the outer wall of the support block, and the other end of the first spring is fixedly connected to the inner wall of the support frame.

[0027] Through the above technical solution: the support block slides on the inner wall of the air guide shaft, ensuring the guiding nature of the support block's movement, so that the support block can accurately approach or move away from the center of the air guide shaft. The two ends of the spring are connected to the support block and the support frame respectively. When the support frame moves, the spring can be stretched or compressed with the relative movement of the support block and the support frame, thereby generating a corresponding pulling force or pushing force to drive the support block to move, ensuring that the support block can move synchronously with the support frame, thereby ensuring the sealing effect of the sealing ring.

[0028] As a further description of the above technical solution:

[0029] A separation tank is fixedly connected to the rear side of the air guide pipe, and an air pump is fixedly connected to the rear side of the separation tank.

[0030] Through the above technical solution: the air pump can extract air from the separation tank, so that the separation tank and the connected air guide pipe, air guide shaft, etc. form a vacuum environment, which facilitates vacuum dehydration operation. The separation tank can separate the gas-liquid mixture generated during the dehydration process, thereby improving the dehydration effect. The air guide pipe plays the role of transporting gas and connecting various components, so that the entire vacuum dehydration system can operate normally.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the rotating disk is driven by motor 2, which drives the support frame to reciprocate through the connecting arm. With the help of spring 1 and damper 1, the sealing ring and the surface groove of the air guide shaft are tightly fitted, filling the gap and maintaining the vacuum environment inside the equipment. Compared with the prior art, this invention improves the problem of poor fit caused by the difficulty in accurately aligning the sealing ring with the groove during installation. The automatic positioning and installation of the sealing ring is achieved through the mechanical structure, which effectively prevents vacuum leakage and improves the continuity and stability of the overall production.

[0033] 2. In this utility model, by means of sliding cooperation between limiting block one and limiting block two, during installation, clamping block two and clamping block one together clamp the limiting post. During disassembly, the limiting post squeezes clamping block two, and after sliding out, clamping block one and clamping block two reset, thereby realizing the quick installation and disassembly of the filter plate, so as to improve the problems of inconvenient filter plate replacement and low maintenance efficiency in the prior art.

Detailed Implementation

[0041] 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.

[0042] This utility model provides an embodiment of a vacuum dehydrator sealing device, including a motor 1. A fixed plate 2 is fixedly connected to the drive end of the motor 1. The fixed plate 2 is used to support and fix the air guide pipe 3, so that the air guide pipe 3 maintains a stable position during equipment operation. The fixed plate 2 is prior art and will not be described in detail here. Multiple air guide pipes 3 are fixedly connected to the rear side of the fixed plate 2. The air guide pipes 3 are used to transmit gas and guide the airflow during the vacuum dehydration process. The fixed plate 2 is prior art and will not be described in detail here. An air guide shaft 4 is fixedly connected to the outer wall of the multiple air guide pipes 3. The air guide shaft 4 provides support and protection for the air guide pipes 3. The surface of the air guide shaft 4 has grooves, which facilitate the initial installation of the sealing ring 57. The air guide shaft 4 is prior art and will not be described in detail here. A sealing mechanism positioning mechanism 5 is installed inside the air guide shaft 4. A bracket 6 is fixedly connected to the bottom end of the motor 1. The bracket 6 provides support for the entire device and ensures the stability of the equipment during operation. The bracket 6 is prior art and will not be described in detail here.

[0043] Specifically, after motor 1 starts, it drives the fixed disk 2 to rotate. The fixed disk 2 drives the air guide shaft 4 to rotate synchronously through the air guide pipe 3. The air guide shaft 4 moves in a circular motion with the fixed disk 2. At the same time, in the positioning mechanism 5, motor 2 drives the rotating disk 52 to rotate counterclockwise. The rotating disk 52 drives the support frame 54 to move up and down reciprocally through the connecting arm 53. When the connecting arm 53 rotates from the upper half to the lower half of the rotating disk 52, the support frame 54 slides downward. The spring 1 582 pulls the support block 56 down along the inner wall of the air guide shaft 4, so that the sealing ring 57 is initially embedded in the groove on the surface of the air guide shaft 4. When the connecting arm 53 rotates from the lower half to the upper half of the rotating disk 52, the support frame 54 slides upward. The spring 1 582 pushes the support block 56 to slide upward. The sealing ring 57 gradually approaches the groove on the surface of the air guide shaft 4 as the support block 56 moves, and finally fits tightly with the groove on the surface of the air guide shaft 4.

[0044] The bracket 6 is equipped with a quick-release mechanism 7, which facilitates the rapid installation and removal of the filter plate 72, improving equipment maintenance efficiency. The sealing mechanism positioning mechanism 5 includes a second motor 51, which provides power for the movement of the sealing mechanism positioning mechanism 5, driving the rotating disk 52 to rotate. The outer wall of the second motor 51 is fixedly connected to the inner wall of the air guide shaft 4, keeping the second motor 51 fixed during operation and ensuring stable power output. The drive end of the second motor 51 is fixedly connected to the rotating disk 52, which rotates under the drive of the second motor 51. The connecting arm 53 drives the support frame 54 to move. The outer wall of the rotating disk 52 is rotatably connected to the connecting arm 53, which plays a transmission role, converting the rotational motion of the rotating disk 52 into the reciprocating sliding of the support frame 54. The other end of the connecting arm 53 is rotatably connected to the support frame 54. The support frame 54 provides installation space and motion guidance for the support block 56 and the elastic component 58. Two connecting blocks 55 are slidably connected to the inner wall of the support frame 54. The connecting blocks 55 connect the support frame 54 and the support block 56, so that the support block 56 can move synchronously with the support frame 54.

[0045] Specifically, in the quick-release mechanism 7, the disc 71 rotates with the sealing ring 57. In the positioning mechanism 5, the motor 51 drives the rotating disc 52 to rotate. The connecting arm 53 converts the circumferential motion of the rotating disc 52 into the up-and-down reciprocating motion of the support frame 54. When the connecting arm 53 rotates from the upper half to the lower half of the rotating disc 52, the support frame 54 slides downward. The spring 582 stretches and pulls the support block 56 down along the inner wall of the air guide shaft 4, so that the sealing ring 57 is initially embedded in the groove of the air guide shaft 4. When the connecting arm 53 rotates to the upper half, the support frame 54 slides upward. The spring 582 compresses and pushes the support block 56 to slide upward. The sealing ring 57 moves closer to the surface groove of the air guide shaft 4 along with the support block 56.

[0046] Support blocks 56 are fixedly connected to the top of the two connecting blocks 55. Support blocks 56 are used to position and fix the sealing ring 57, allowing the sealing ring 57 to be fully installed. The sealing ring 57 is fixedly connected to the outer wall of the support blocks 56. A groove is formed inside the sealing ring 57, and the outer wall of the groove can perfectly fit with the outer wall of the support block 56. During initial installation, the sealing ring 57 can slide along the outer wall of the support block 56 using the groove. When the groove of the sealing ring 57 perfectly fits the support block 56, the sealing ring 57 is finally installed. To reduce the risk of misalignment of the sealing ring 57 during installation, the support frame 54 is equipped with an elastic component 58. The elastic component 58 provides elastic force and cushioning for the movement of the support block 56, ensuring a stable sealing process. The elastic component 58 includes a damper 581, which is used to slow down the movement speed of the support block 56 and prevent it from being violently impacted by the spring force. One end of the damper 581 is fixedly connected to the outer wall of the support frame 54 to ensure that the damper 581 remains in a fixed position within the support frame 54, providing a stable cushioning effect.

[0047] Specifically, the support frame 54 drives the support block 56 to slide up and down along the inner wall of the air guide shaft 4 via two connecting blocks 55. The sealing ring 57 moves synchronously with the support block 56. The groove on the inner wall of the sealing ring 57 precisely fits the outer wall of the support block 56 to avoid misalignment. In the elastic component 58, the spring 582 is sleeved outside the damper 581. When the support frame 54 slides down, the spring 582 stretches and pulls the support block 56 down, so that the sealing ring 57 is initially embedded in the groove of the air guide shaft 4. When the support frame 54 slides up, the spring 582 compresses and pushes the support block 56 up. The support block 56 drives the sealing ring 57 closer to the groove of the air guide shaft 4. During this process, the damper 581 always suppresses the movement speed of the support block 56. By buffering the elastic force of the spring 582, it avoids violent impact on the support block 56 and ensures that the sealing ring 57 smoothly fits the gap to achieve a seal.

[0048] A spring 582 is fitted around the damper 581. The spring 582 generates a pulling or pushing force on the support block 56 through elastic deformation, driving the support block 56 to move. A separation tank 8 is fixedly connected to the rear side of the air guide pipe 3. The separation tank 8 is used to separate the gas-liquid mixture generated during the dehydration process. The separation tank 8 is prior art and will not be described in detail here. A vacuum pump 9 is fixedly connected to the rear side of the separation tank 8. The vacuum pump 9 is used to extract the gas inside the disc 71, forming a vacuum environment inside the disc 71 to provide conditions for the dehydration process. The vacuum pump 9 is prior art and will not be described in detail here.

[0049] Specifically, spring 582 undergoes elastic deformation as the support frame 54 moves. When the support frame 54 slides downward, spring 582 is stretched and generates tension, causing the support block 56 to slide down, so that the sealing ring is initially embedded in the groove of the air guide shaft 4. When the support frame 54 slides upward, spring 582 is compressed and generates thrust, pushing the support block 56 upward, causing the sealing ring 57 to gradually fit into the groove of the air guide shaft 4. During this process, damper 581 always suppresses the movement speed of the support block 56 and buffers the spring force to avoid impact. The vacuum pump 9 is used to extract air from the separation tank 8. The suction force transmitted from the separation tank 8 introduces the gas inside the disc 71 into the separation tank 8 through the air guide pipe 3, thus forming an internal vacuum in the disc 71, providing conditions for the dehydration process of the disc 71.

[0050] Reference Figure 2 , Figure 4 , Figure 5The quick-release mechanism 7 includes a disc 71, which provides an installation base for the filter plate 72 and cooperates with the sealing ring 57 to achieve a seal. The inner wall of the disc 71 is fixedly connected to the outer wall of the sealing ring 57, so that the disc 71 and the sealing ring 57 are tightly connected to ensure the sealing effect. Multiple filter plates 72 are detachably connected to the outer wall of the disc 71. The filter plates 72 are used to filter materials and achieve dewatering. The detachable design makes them easy to replace. Two handles 73 are fixedly connected to the outer wall of the filter plate 72. The handles 73 are convenient for operators to hold and facilitate the installation and removal of the filter plates 72. Two limiting blocks 74 are fixedly connected to the outer wall of the filter plate 72. The limiting blocks 74 cooperate with the limiting blocks 75 to achieve the positioning and fixation of the filter plate 72 on the disc 71. Multiple limiting blocks 75 are fixedly connected to the inner wall of the disc 71. The limiting blocks 75 provide installation and sliding tracks for the limiting blocks 74 to ensure the accurate installation position of the filter plate 72.

[0051] Specifically, in the quick-release mechanism 7, the disc 71 rotates synchronously with the sealing ring 57. The disc 71 forms a sliding fit with the limiting block 74 of the filter plate 72 through the limiting block 75. During installation, the operator holds the handle 73 and pushes the filter plate 72 radially in. The limiting block 74 slides along the inner wall groove of the limiting block 75 until the filter plate 72 is in contact with the outer wall of the disc 71. At this time, the locking grooves of the limiting block 74 and the limiting block 75 are precisely aligned, realizing the filter... Positioning of plate 72: During disassembly, pull the handle 73 in the opposite direction, and the first limiting block 74 slides out along the groove of the second limiting block 75, separating the filter plate 72 from the disc 71. This structure, through the sliding guidance of the first limiting block 74 and the second limiting block 75, combined with the gripping operation of the handle 73, enables the filter plate 72 to be quickly loaded and unloaded on the disc 71. This ensures that the filter plate 72 rotates synchronously with the disc 71 to complete the filtration operation, and also facilitates the convenient replacement of the filter plate 72 during maintenance.

[0052] A limiting post 76 is fixedly connected to the inner wall of limiting block 2 75. The limiting post 76 cooperates with the limiting component 77 to limit the position of limiting block 1 74 and fix the filter plate 72. The limiting component 77 is provided inside the limiting block 1 74. The limiting component 77 is used to clamp the limiting post 76 to fix the filter plate 72. The limiting component 77 includes a support post 771, which provides installation support for clamping block 1 772 to ensure its stable position. The outer wall of the support post 771 is fixedly connected to the inner wall of the limiting block 1 74, so that the support post 771 is fixed within the limiting block 1 74. The inner wall of the support column 771 is fixedly connected to a clamping block 772. The clamping block 772 limits the position of the limiting column 76 under the action of the spring 775, thus assisting in fixing the filter plate 72. The inner wall of the limiting block 74 is fixedly connected to two dampers 773. The dampers 773 are used to buffer the movement of the clamping block 774 and prevent it from moving too violently. The other end of the damper 773 is fixedly connected to a clamping block 774. The clamping block 774 limits the position of the limiting column 76 under the action of the spring 776, thus fixing the filter plate 72.

[0053] Specifically, the limiting post 76 and the limiting assembly 77 form a clamping fit. When installing the filter plate 72, the first limiting block 74 slides along the second limiting block 75. The limiting post 76 first squeezes the second clamping block 774, causing it to move to both sides against the elastic force of the third spring 776. After the limiting post 76 slides into the interior of the first limiting block 74, the third spring 776 returns to its original position and pushes the second clamping block 774 to clamp one side of the limiting post 76. At the same time, the limiting post 76 squeezes the first clamping block 772, causing the first clamping block 772 to compress the second spring 775. After resetting, the clamping block 772 is pushed to clamp the other side of the limiting post 76, forming a bidirectional limit. The damper 773 provides buffering when the clamping block 774 moves, suppressing its violent shaking. During disassembly, the filter plate 72 is pulled outward, and the limiting post 76 squeezes the clamping block 774, causing the spring 776 to be compressed again. After disengaging from the limiting block 74, the clamping block 772 is reset under the action of the spring 775, and the clamping block 774 is reset under the action of the spring 776, finally realizing the rapid disassembly of the filter plate 72.

[0054] A second spring 775 is sleeved on the outside of the support column 771. The second spring 775 generates thrust through elastic deformation, pushing the clamping block 772 to clamp the limiting column 76. A third spring 776 is sleeved on the outside of the damper 773. The third spring 776 generates elastic force through elastic deformation, driving the clamping block 774 to clamp the limiting column 76. The outer wall of the clamping block 774 is detachably connected to the outer wall of the limiting column 76. This detachable connection facilitates the installation and removal of the filter plate 72. The outer wall of the limiting block 74 is slidably connected to the inner wall of the limiting block 75, allowing the limiting block 74 to slide along the limiting block 75, thus realizing the installation and removal of the filter plate 72. The outer walls of both clamping blocks 774 are slidably connected to the inner wall of the limiting block 74, allowing the clamping blocks 774 to slide within the limiting block 74, thus realizing the clamping and releasing of the limiting column 76.

[0055] Specifically, when the first limiting block 74 slides along the inner wall of the second limiting block 75, the limiting post 76 inserts into the interior of the first limiting block 74. The limiting post 76 first squeezes the second clamping block 774, causing the second clamping block 774 to slide upwards and downwards against the elastic force of the third spring 776. The damper 773 is used to suppress the sliding speed of the second clamping block 774. After the limiting post 76 has slid in completely, the third spring 776 returns to its original position and pushes the second clamping block 774 to clamp the limiting post 76. At the same time, the limiting post 76 squeezes the first clamping block 772, causing the first clamping block 772 to compress the spring. After spring 775 returns to its original position, it pushes clamping block 772 against the other side of limiting post 76. Clamping block 772 and clamping block 774 form a bidirectional clamp. When disassembling, the filter plate 72 is pulled outward, and limiting post 76 squeezes clamping block 774, causing spring 776 to be compressed again. Clamping block 774 slides up and down, while clamping block 772 returns to its original position under the action of spring 775. Limiting post 76 is released from the clamping state, and limiting block 74 slides out from the inner wall of limiting block 75, realizing the quick disassembly of filter plate 72.

[0056] The inner wall of clamping block 772 is slidably connected to the inner wall of limiting block 74, allowing clamping block 772 to slide within limiting block 74. This, in conjunction with clamping block 774, achieves bidirectional limiting of the limiting post 76. One end of spring 776 is fixedly connected to the outer wall of clamping block 774, and the other end is fixedly connected to the inner wall of limiting block 74. This connection method allows spring 776 to provide elastic force to clamping block 774, thus achieving the clamping action. The other ends of the two springs 776 are fixedly connected to the inner wall of the limiting block 74, ensuring that the two clamping blocks 774 can obtain elastic force and symmetrically clamp the limiting post 76. One end of the spring 775 is fixedly connected to the outer wall of the clamping block 772, and the other end of the spring 775 is fixedly connected to the inner wall of the limiting block 74. This connection method allows the spring 775 to provide thrust to the clamping block 772, ensuring that the clamping block 772 fits tightly against the limiting post 76.

[0057] Specifically, when the limiting post 76 is inserted into the limiting block 74, the limiting post 76 first squeezes the clamping block 774, causing the clamping block 774 to slide up and down along the inner wall of the limiting block 74. The clamping block 774 compresses the springs 776 at both ends. At the same time, the limiting post 76 squeezes the clamping block 772, causing the clamping block 772 to slide along the inner wall of the limiting block 74 and compress the spring 775. When the limiting post 76 is fully inserted, the spring 776 returns to its original position and pushes the clamping block 774 inward. Lateral sliding, symmetrically clamping one side of the limiting post 76, spring two 775 resets and pushes clamping block one 772 to slide closer to the limiting post 76, clamping block one 772 clamps the other side of the limiting post 76, thus forming a bidirectional limiting. When disassembling, pull the filter plate 72 outward, the outer wall of the limiting post 76 squeezes clamping block two 774, causing clamping block two 774 to slide up and down again to compress spring three 776, while clamping block one 772 completes reset under the pushing force of spring two 775.

[0058] Working principle: Motor 2 51 drives the rotating disk 52 to rotate. The rotating disk 52 drives the support frame 54 to reciprocate through the connecting arm 53. When the connecting arm 53 rotates from the upper part of the rotating disk 52 to the lower part of the rotating disk 52, the connecting arm 53 drives the support frame 54 to slide downward. When the connecting arm 53 rotates from the lower part of the rotating disk 52 to the upper part of the rotating disk 52, the connecting arm 53 drives the support frame 54 to slide upward.

[0059] Before the sealing ring 57 is inserted, when the connecting arm 53 drives the support frame 54 to slide downward, the spring 582 inside the support frame 54 is stretched. The spring 582 generates a downward pulling force on the support block 56 through elastic deformation. The spring 582 pulls the support block 56 to move downward synchronously. The damper 581 is used to slow down the movement speed of the support block 56 to avoid the support block 56 from being violently impacted by the spring tension. At this time, the support block 56 slides into the interior of the air guide shaft 4. The surface of the air guide shaft 4 has a groove. The groove on the surface of the air guide shaft 4 can facilitate the initial installation of the sealing ring 57, and thus make it easier for the operator to initially embed the sealing ring 57 into the surface of the air guide shaft 4.

[0060] After the sealing ring 57 is inserted, when the connecting arm 53 drives the support frame 54 to slide upward, the spring 582 inside the support frame 54 is compressed. The spring 582 generates an upward thrust through elastic deformation. The spring 582 pushes the support block 56 to move upward synchronously. At this time, the damper 581 suppresses the movement speed of the support block 56 to prevent it from being violently impacted by the thrust of the spring 582. The sealing ring 57 has a groove inside that fits with the surface of the support block 56. During the process of the support block 56 sliding out of the air guide shaft 4, the inner wall of 57 will slide along the outer wall of the support block 56. When the support block 56 slides out of the air guide shaft 4 completely, the inner groove of the sealing ring 57 fits with the surface of the support block 56. At this time, the positioning and installation operation of the sealing ring 57 is completed.

[0061] The operator holds handle 73 and inserts the limiting block 74 on filter plate 72 into the limiting block 75 on the inner wall of disc 71. Limiting block 74 slides along the inner wall of limiting block 75. First, limiting post 76 contacts the outer wall of clamping block 774 and slides along it. Simultaneously, limiting post 76 presses against clamping block 774, causing both clamping blocks 774 to move away from each other, compressing spring 776. When limiting post 76 slides into the interior of limiting block 74, spring 776 releases its elasticity, carrying... The two clamping blocks 774 move closer to each other. When the two clamping blocks 774 come into contact, they limit one side of the limiting post 76. At the same time, as the limiting post 76 slides in, the limiting post 76 presses the clamping block 772 towards the filter plate 72. The clamping block 772 drives the spring 775 to be compressed together. The spring 775 pushes the clamping block 772 towards the limiting post 76 with its own elasticity, so that the clamping block 772 limits the other side of the limiting post 76. This completes the installation operation of the filter plate 72.

[0062] The operator holds the handle 73 and applies force outward, sliding the first limiting block 74 outward along the inner wall of the second limiting block 75. During this process, the outer wall of the limiting post 76 slides along the outer wall of the second clamping block 774, gradually squeezing the two clamping blocks 774 to both sides, causing the third spring 776 to be compressed and store force. When the limiting post 76 completely slides out of the clamping range of the second clamping block 774, the third spring 776 releases its elasticity, causing the two clamping blocks 774 to reset. At the same time, the first clamping block 772 resets synchronously under the natural extension force of the second spring 775. Finally, the first limiting block 74 is completely pulled out from the inner wall of the second limiting block 75, separating the filter plate 72 from the disc 71, completing the disassembly operation.
