[0030] DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0031] In order to make the purpose , technical scheme and advantages of the application more clear, the application is further explained in detail in combination with the drawings and embodiments . It should be understood that the speci fic embodiments described herein are used only to interpret the application and not to define the application .
[0032] In order to solve the technical problem of how to avoid the filter cake from sticking to the filter board, this application provides an automatic discharge filter press that can vibrate the filter board during the process of releasing the filter cake , so as to avoid the filter cake from sticking to the filter board .
[0033] It should be noted that the automatic discharge filter press used in this application is used for but not limited to the pulp bottom flow, etc . , in this application, only the automatic discharge filter press and the automatic discharge filter press applied to other types of equipment is the same as the principle applied to the pulp bottom flow, which is not described here .
[0034] Referring to FIG . 1 , a schematic diagram of the embodiment of this application, the automatic discharge press includes a frame 100 , a moving assembly 200 , a blocking assembly 400 , and several filter plates 300 sliding on the frame 100 , and the filter plate 300 can deflect to set an angle relative to the frame 100 . The moving assembly 200 drives the filter plate 300 to successively drive the filter plate 300 to slide in the first direction relative to the frame 100 . The blocking assembly 400 includes a limiting member 410 and a driver 420 that is connected to the limit member 410 for moving in the second direction . The limiting member 410 extends at least partially to the upper or lower side of the barrier filter cake in the first direction . Where , the first direction is opposite to the second direction .
[0035] In this embodiment , when the automatic discharge filter press completes the pressing work, the filter plate 300 can be moved along the frame 100 by moving the assembly 200 , thereby opening the spacing between the filter plate 300 , so that the filter cake can fall from the gap of the filter plate 300 . The limiting member 410 blocks the upper or lower side of the filter plate 300 so that the filter plate 300 turns and causes vibration, thus ef fectively avoiding the cake to the filter plate 300 . The flipped filter plate 300 may also be removed from the limiting plate 410 to align the limiting member 410 to the next filter plate 300 . Meanwhile , the limiting member 410 is allowed to move in the second direction, so that the limiting member 410 can contact each filter plate 300 individually . The above automatic unloading filter press can vibrate the filter plate 300 during releasing the filter cake , thereby ef fectively avoiding the filter cake from sticking to the filter plate 300 .
[0036] It should be emphasi zed here that the frame 100 is usually laid with a sliding guide for the filter plate 300 , and the filter plate 300 has a mating gap between the guide and the guide , on the other hand, the width of the filter plate 300 is narrow, so that the filter plate 300 can be slightly turned relative to the slide .
[0037] As long as the embodiment of the limiting member 410 which blocks the movement of the filter plate 300 is feasible , In some of these embodiments , The limit member 410 includes a first slide holder 411 , a stop lever 412 , and a switching portion 413 , The first sliding seat 411 is disposed to the frame 100 along the arrangement direction of a number of filter plates 300 , The stop lever 412 is movable and set on the first slide seat 411 , The moving track of the retaining lever 412 has a first position blocking the movement of the filter plate 300 , And having a second position far away from the filter plate 300 to allow the filter plate 300 to move , Switching section 413 transmission connection retaining lever 412 , To drive the lever 412 to switch between the first and second position .
[0038] In this embodiment , the filter plate 300 has two sliding directions . When the filter plate 300 is far away from each other, the filter plate 300 can be slightly turned over . Then the baf fle plate 412 is switched to the first position by the switching unit 413 , and then the filter plate 300 can be moved by the baf fle plate 412 . Further forcing the filter plate 300 to flip the vibration . When the filter plate 300 moves in a direction close to each other, the filter plate 300 is tightly close between the filter plates 300 . The lever 412 may be switched to the second position by the switching section 413 , losing the block of the lever 412 and allowing the filter plate 300 to move freely .
[0039] On the basis of the above embodiments , in some embodiments , one end of the lever 412 is rotatably mounted to the first sliding seat 411 , the switching portion 413 includes the cylinder 4131 , the piston rod hinge lever 412 of cylinder 4131 , and the cylinder block of cylinder 4131 hinged with the first sliding seat 411 .
[0040] In this embodiment , since the piston rod of cylinder 4131 hinges the retaining lever 412 , the cylinder block of cylinder 4131 hinges the first slide seat 411 . When the piston rod of the cylinder 4131 moves relative to the cylinder block of the cylinder 4131 , the retaining rod 412 may be driven to rotate against the first slide seat 411 .
[0041] In some of these embodiments , the block assembly 400 includes a drive 420 connected to the first slide 411 to drive the first slide 411 to slide .
[0042] In this embodiment , the first sliding plate 411 is driven by the driving member 420 so that the relative positions of the first sliding holder 411 and the filter plate 300 can be adj usted so that the first sliding holder 411 can be aligned with the target filter plate 300 . Further, the first slide seat 411 may be left at any position on its sliding track by the driving member 420 .
[0043] As long as embodiments in which the first holder 411 can slide relative to the frame 100 are feasible , in some embodiments , the frame 100 has a guide rod 110 , the first holder 411 has a guide hole 4111 , and the guide hole 4111 is set on the guide rod 110 to slide the first holder 411 along the guide rod 110 .
[0044] In this embodiment , a guide hole 4111 is provided on the first slide seat 411 . Since the guide hole 4111 is set above the guide rod 110 , the first guide seat 411 can have a stable sliding track under the guiding action of the guide rod 110 .
[0045] On the basis of the above embodiments , in some of these embodiments , the first slide seat 411 has a wire hole 4112 , the drive member 420 includes a wire rod 421 and the motor 422 , the wire rod 421 is connected with the wire hole 4112 and turns the motor 422 to push the first slide seat 411 along the guide rod 110 .
[0046] In this embodiment , since the rod 421 and the wire hole 4112 are screwed, the rod 421 is rotated by the motor 422 , and the first sliding seat 411 can be moved through the rotating wire 421 .
[0047] Understandably, The above limit member 410 is obviously not the only embodiment , The present application also provides additional embodiments of the limit piece 410 , among, The limit member 410 includes a second slide seat 414 and a f lexible strip 415 , The second slide holder 414 is slid to the frame 100 along the arrangement direction of a number of filter plates 300 , One end of the flexible strip 415 is connected to the second sliding block 414 , The other end of the flexible strip 415 serves to block the filter plate 300 , The flexible strip 415 contacts with the moving filter plate 300 to flip the filter plate 300 , The flexible strip 415 can be bent under the push of the filter plate 300 to remove the moving filter plate 300 from the flexible strip 415 .
[0048] In this embodiment , after the second slide holder 414 is aligned with the filter plate 300 , the filter plate 300 is blocked by the flexible strip 415 , so that the moving filter plate 300 can vibrate . As the filter plate 300 continues to move , the filter plate 300 forces the flexible strip 415 to bend until the flexible strip 415 cannot prevent the filter plate 300 from moving so that the filter plate 300 can cross the flexible strip 415 . Furthermore , since the flexible strip 415 can be deformed, the flexible strip 415 does not block the translation of the filter plate 300 regardless of how the individual filter plates 300 are translated .
[0049] In some of these embodiments , the moving assembly 200 includes a drive trolley 210 that slides down to the rack 100 and can align any filter plate 300 that has a third state connecting the filter plate 300 to drive the filter plate 300 and a fourth state that deviates from the filter plate 300 and adj usts the position relative to the filter plate 300 .
[0050] In this embodiment , the drive trolley 210 can be moved on the rack 100 to drive the filter plate 300 through the drive trolley 210 , the drive trolley 210 can be adj usted to a third state to make the drive trolley 210 and the filter plate 300 connected, and the drive trolley 210 can be used to slide the filter plate 300 . At the need to adj ust the relative position of the filter plate 300 and the driving trolley 210 , the drive cart 210 may be adj usted to a fourth state , and since the drive cart 210 is detached from the filter plate 300 , the driving cart 210 may move relative to the filter plate 300 .
[0051] In some of these embodiments , the limiting member 410 blocks the top end of the filter plate 300 to tilt the filter plate 300 .
[0052] In this embodiment , since the limiting member 410 blocks the top of the filter plate 300 , the filter plate 300 slopes to separating the filter cake from the filter plate 300 . It should be emphasi zed here that there is a mating gap between the filter plate 300 and the frame 100 , so that the filter plate 300 can shake slightly relative to the frame 100 under the external force
[0053] As long as the embodiments that connect the drive cart 210 and the filter plate 300 are feasible , in some embodiments , the drive cart 210 has the electromagnet 211 , and the drive cart 210 is in the third state , the electromagnet 211 is magnetically and adsorbs the bottom end of the filter plate 300 , and the drive cart 210 in the fourth state loses the magnetic magnet 211 to enable the drive cart 210 to move relative to the filter plate 300 .
[0054] In this embodiment , when the electromagnets 211 is magnetic, the electromagnet 211 and the filter plate 300 can cause the drive trolley 210 and move the f ilter plate 300 to each other . When the electromagnet 211 is not magnetic, the driving trolley 210 is free to move relative to the filter plate 300 due to the loss of the magnetic limitation .
[0055] In some of these embodiments , the moving assembly 200 includes a plurality of limit ropes 220 , 220 spaced between a number of filter plates 300 , and the limit rope 220 is each connected to two adj acent filter plates 300 .
[0056] In this embodiment , since having a limit rope 220 between two adj acent filter plates 300 , the limit rope 220 determines the maximum spacing of adj acent fi lter plates 300 to avoid the excessive spacing of adj acent f ilter plates 300 . Meanwhile , since the limit rope 220 connects the various filter plates 300 together, the other filter plates 300 can be driven to move together while sliding at the end filter plate 300 .
[0057] It should be emphasi zed here that the technical scheme provided in the present application only exposes the relevant characteristics of the automatic discharge filter press on how to prevent the filter cake from sticking to the sticky filter plate 300 . The automatic filter press shall at least have a pressure assembly to press the filter plate 300 together and a conveyor belt to handle the falling filter plate 300 , an airtight pipe to control the expansion of the internal diaphragm of the filter plate 300 , and an inlet and outlet water pipe with the imported slurry and the outlet water . Since the above features are mature prior technology, although the present application fails to speci fy the above technical features , it does not mean that the present technical scheme has the defect of insuf ficient disclosure of technical contents .
[0058] To better understand the present application, the technical scheme of this application is described in detail below in combination with FIGS . 1 to 2 :
[0059] When the automatic unloading filter press completes the filter press , the driving trolley 210 can be used to slide the filter plate 300 in turn . Thus , the spacing between the individual filter plates 300 is pulled apart , so that the filter cake can fall from the gap of the filter plate 300 . Since a limit rope 220 is provided between the two adj acent filter plates 300 , the limit rope 220 determines the maximum spacing of the adj acent filter plates 300 to avoid excessive spacing of the adj acent filter plates 300 . The first sliding seat 411 is translated by the driving member 420 , so the relative positions of the first sliding holder 411 and the filter plate 300 can be adj usted so that the first s liding seat 411 can be aligned to the target filter plate 300 . The lever 412 is switched to a first position by the switching section 413 , so that the filter plate 300 can be moved by the lever 412 . Furthermore , the filter plate 300 is temporarily blocked to vibrate the filter plate 300 to ef fectively avoid the filter cake from sticking to the filter plate 300 . The lever 412 may be switched to the second position by the switching section 413 , losing the barrier of the lever 412 and allowing the filter plate 300 to move freely . To align the limit member 410 to the next filter plate 300 . The above automatic unloading filter press can vibrate the filter plate 300 during releasing the filter cake , thereby ef fectively avoiding the filter cake from sticking to the filter plate 300 .
[0060] The speci fic embodiment of the present application described above does not constitute a limitation of the scope of protection of this application . Any other corresponding changes and deformation made in accordance with the technical conception of the application shall be covered within the protection of the claims of the application .
