Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a waterproof coating filter press. Background Technology

[0002] Waterproof coating filter press is a key piece of equipment used for solid-liquid separation in the production process of waterproof coatings. It is mainly used to remove impurities, undispersed particles or by-products after reaction from the coating to improve the purity and performance of the coating.

[0003] According to a leak-proof sealed filter press (publication number: CN222550215U), the aforementioned application describes a liftable sealing plate installed at the front end of the filter press housing. When the filter plates need to be compressed, the drive motor is activated, causing the threaded rod to rotate. This allows the threaded sleeve on the outside of the threaded rod to move the sealing plate downwards under the action of the threads. The positioning block on the left side of the sealing plate then moves the guide slider in the guide rail downwards, allowing the sealing plate to move smoothly downwards. This enables the sealing plate to quickly seal the front end of the filter press housing, effectively preventing gas from leaking to the outside of the filter press housing during the compression process, thus improving the safety of the device during use.

[0004] However, in the aforementioned application, when the sealing plate is opened laterally for filter plate replacement or equipment maintenance, the sealing plate remains open solely due to its own weight or rotation mechanism because no effective limit or locking structure is provided. If operators or other external personnel accidentally touch the sealing plate, it may suddenly close, posing a serious safety hazard and potentially causing injury to workers who may be pinched or struck. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof coating filter press to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof coating filter press, comprising a filter press body, a cabinet mounted on the outer surface of the filter press body, a fixed seat fixed on the outer surface of the cabinet, a rotating shaft rotatably connected to the inner side of the fixed seat, a cabinet door rotatably connected through the rotating shaft, and protective components and limiting components provided on the surface and inside of the fixed seat, the rotating shaft, and the cabinet door;

[0007] The protective components include:

[0008] The card slot is used to limit the position of the card plate.

[0009] A cavity is used to stabilize its internal structure.

[0010] Circular blocks are used to synchronize the movement of various components.

[0011] Linkage mechanism: The linkage mechanism is used to release the limit switch to facilitate closing the cabinet door.

[0012] Preferably, the slot is located on the inner wall of the cabinet door. A cavity is formed inside the rotating shaft, and a circular block is rotatably connected to the inner wall of the cavity. A connecting hole is formed on the outer surface of the circular block, and a short rod abuts against the inner wall of the connecting hole. A locking plate is fixed to the end of the short rod away from the connecting hole. The side of the locking plate away from the short rod passes through the rotating shaft, and the locking plate is slidably connected to the rotating shaft. A rotating rod is fixed to the bottom of the circular block, and a spiral spring is fixed to the outer surface of the rotating rod. The end of the spiral spring away from the rotating rod is fixed to the inner wall of the cavity. When the circular block rotates, the inner wall of the connecting hole abuts against the surface of the short rod, which can drive the locking plate to move radially synchronously. When the cabinet door rotates, under the action of the spiral spring, the circular block can reciprocate, causing the locking plate to move back and forth into the slot, without hindering the opening of the cabinet door. At the same time, the side of the locking plate away from the inclined surface abuts against the inner wall of the slot, preventing the cabinet door from reversing.

[0013] Preferably, the linkage includes a first fixing plate, which is disposed on the top of the circular block. A long rod is rotatably connected to the top of the circular block, and the top of the long rod passes through a rotating shaft, and the long rod is rotatably connected to the rotating shaft. A second fixing plate is fixed to the top of the circular block, and a knob is rotatably connected to the top of the fixing seat. The output shaft of the knob passes through the fixing seat, and the output shaft of the knob is fixed to the top of the long rod. When the knob is rotated, the surfaces of the first fixing plate and the second fixing plate abut against each other, which drives the circular block to rotate, making it easier for the locking plate to disengage from the locking slot.

[0014] Preferably, the limiting component includes a fixing ring, which is fixed to the outer surface of the knob. A spring is fixed to the bottom of the fixing ring, and a pull ring is fixed to the bottom of the spring. The pull ring is slidably connected to the outer surface of the knob, and a locking rod is fixed to the bottom of the pull ring. A limiting groove is provided on the top of the fixing seat. Pulling the pull ring can disengage the locking rod from the limiting groove, thereby unlocking the knob. When the locking rod resets, it locks the knob to prevent accidental activation when the cabinet door is opened, ensuring the cabinet door is stable.

[0015] Preferably, the side of the card plate away from the short rod is set as an inclined surface, which allows the card plate to move into the cavity when it is pressed.

[0016] Preferably, the connecting hole is arc-shaped, and when the circular block rotates, its inner wall abuts against the surface of the short rod, which can drive the card plate to move radially synchronously.

[0017] Compared with the prior art, this utility model provides a waterproof coating filter press, which has the following beneficial effects:

[0018] 1. This waterproof coating filter press, through its protective components, ensures that when the cabinet door rotates, the inner wall of the slot contacts the inclined surface of the plate, pushing the plate inward and simultaneously causing the short rods to slide within the connecting holes, causing the circular block to rotate in the forward direction. At this time, all the short rods and the plate move radially synchronously, and the rotating shaft rotates accordingly, tightening the spiral spring. When the plate aligns with the slot, the spiral spring releases its elasticity, causing the circular block to rotate in the opposite direction, pulling the plate back into the slot. At this point, the inner wall of the slot abuts against the plane of the plate, preventing the cabinet door from rotating in the opposite direction and avoiding accidental closure that could cause injury. To release the limit, rotating the knob will cause the circular block to rotate, pulling the short rods and plate out of the slot through the connecting holes, allowing the cabinet door to close normally.

[0019] 2. This waterproof coating filter press, through the setting of the limiting component, can release the locking rod from the limiting groove by pulling the pull ring and unlocking the knob, which is convenient for releasing the limit on the cabinet door in the future; when the locking rod is reset, the knob is locked to prevent accidental contact when the cabinet door is opened, and to ensure the cabinet door is stable.

[0028] like Figures 1-7 As shown, this utility model provides a technical solution: a waterproof coating filter press, including a filter press body 1, a cabinet 6 installed on the outer surface of the filter press body 1, a fixed seat 2 fixed on the outer surface of the cabinet 6, a rotating shaft 3 rotatably connected to the inner side of the fixed seat 2, and a cabinet door 4 rotatably connected through the rotating shaft 3. The fixed seat 2, the rotating shaft 3, and the cabinet door 4 are provided with protective components 7 and limiting components 8 on their surfaces and inside. The protective components 7 include: a slot 70, a cavity 71, a round block 72, a connecting hole 73, a short rod 74, a locking plate 75, a rotating rod 76, a spiral spring 77, a linkage 78, a first fixed plate 780, a second fixed plate 781, a knob 782, and a long rod 783.

[0029] A slot 70 is formed on the inner wall of the cabinet door 4. A cavity 71 is formed inside the rotating shaft 3. A round block 72 is rotatably connected to the inner wall of the cavity 71. A connecting hole 73 is formed on the outer surface of the round block 72. A short rod 74 abuts against the inner wall of the connecting hole 73. A locking plate 75 is fixed to the end of the short rod 74 away from the connecting hole 73. The side of the locking plate 75 away from the short rod 74 passes through the rotating shaft 3, and the locking plate 75 is slidably connected to the rotating shaft 3. A rotating rod 76 is fixed to the bottom of the round block 72. A spiral spring 77 is fixed to the outer surface of the rotating rod 76. The end of the spiral spring 77 away from the rotating rod 76 is fixed to the inner wall of the cavity 71. The linkage 78 includes a fixing plate 780, which is set on the top of the round block 72. A long rod 78 is rotatably connected to the top of the round block 72. 3. The top of the long rod 783 passes through the rotating shaft 3, and the long rod 783 is rotatably connected to the rotating shaft 3. The top of the round block 72 is fixed with a fixing plate 781. The top of the fixing seat 2 is rotatably connected with a knob 782. The output shaft of the knob 782 passes through the fixing seat 2, and the output shaft of the knob 782 is fixed to the top of the long rod 783. The side of the card plate 75 away from the short rod 74 is set as an inclined surface, and the connecting hole 73 is set as an arc. When the cabinet door 4 rotates, the inner wall of the card slot 70 abuts against the inclined surface of the card plate 75, driving the card plate 75 to move towards the cavity 71. At the same time, the short rod 74 moves in the connecting hole 73 and abuts against the hole wall, thereby driving the round block 72 to rotate forward, so that each short rod 74 and the card plate 75 move radially synchronously. At this time, the rotating rod 76 rotates and coils the spiral spring 77. When the locking plate 75 aligns with the slot 70, the spiral spring 77 releases, causing the short rod 74 and the round block 72 to reverse and reset. The connecting hole 73 then pushes the locking plate 75 back into the slot 70. At this time, the inner wall of the slot 70 abuts against the flat side of the locking plate 75, which can limit the reverse rotation of the cabinet door 4 and prevent accidental closure that could cause injury. If it is necessary to close the cabinet door 4, rotate the knob 782 to make the first fixing plate 780 abut against the second fixing plate 781, causing the round block 72 to rotate. The inner wall of the connecting hole 73 pulls the short rod 74 and the locking plate 75 radially away from the slot 70, thus releasing the limit and allowing the cabinet door 4 to close normally.

[0030] The limiting component 8 includes a retaining ring 80, which is fixed to the outer surface of the knob 782. A spring 81 is fixed to the bottom of the retaining ring 80, and a pull ring 82 is fixed to the bottom of the spring 81. The pull ring 82 is slidably connected to the outer surface of the knob 782, and a locking rod 83 is fixed to the bottom of the pull ring 82. A limiting groove 84 is provided on the top of the fixing base 2. Pulling the pull ring 82 can disengage the locking rod 83 from the limiting groove 84, thereby releasing the limiting of the knob 782; conversely, when the locking rod 83 is engaged in the limiting groove 84, it can restrict the rotation of the knob 782. This design can effectively prevent accidental activation of the knob 782 when the cabinet door 4 is opened, ensuring the stability of the cabinet door 4.

[0031] When cabinet door 4 needs to be opened, it can be unlocked using the handle on the surface of cabinet door 4. Cabinet door 4 can then be opened normally by rotating it. Simultaneously, as cabinet door 4 rotates, the inner wall of the slot 70 abuts against the inclined surface of the plate 75, causing the plate 75 to move closer to the cavity 71. At the same time, the plate 75 moves the short rod 74 into the connecting hole 73. The surface of the short rod 74 then abuts against the inner wall of the connecting hole 73, causing the round block 72 to rotate clockwise. This allows the short rods 74 and the plate 75 to move radially synchronously. The rotating rod 76 rotates synchronously, causing the spiral spring 77 to coil. When the plate 75 is parallel to the slot 70, the spiral spring 77 releases, causing the short rods 74 and the round block 72 to rotate in reverse and reset. The connecting hole 73 then resets the short rods 74 and the plate 75, allowing the plate 75 to enter the slot 70 without affecting the normal opening of cabinet door 4. The inner wall of the slot 70 abuts against the side of the plate 75 away from the inclined surface. When the door is touched, it will limit the cabinet door 4, preventing it from reversing and resetting. This avoids accidental closure of the cabinet door 4 and potential injury. At this time, the filter plates inside the filter press body 1 can be replaced or maintained normally. When it is needed again, pull the pull ring 82 to disengage the locking rod 83 from the limiting groove 84, releasing the limit on the knob 782. Conversely, when the locking rod 83 enters the limiting groove 84, it can limit the knob 782, preventing accidental activation of the knob 782 when the cabinet door 4 is open and affecting the stability of the cabinet door 4. When the knob 782 is turned, the surface of the first fixing plate 780 abuts against the outer surface of the second fixing plate 781, which will synchronously drive the round block 72 to rotate. At this time, the inner wall of the connecting hole 73 abuts against the outer surface of the short rod 74, which will pull the short rod 74 and the locking plate 75 to move radially and disengage from the locking groove 70, thus releasing the limit on the cabinet door 4. The cabinet door 4 can then be closed normally for subsequent normal use.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
