Description

Technical Field

[0001] The present application relates to the technical field of filter press cake unloading, and in particular to a filter press cake unloading mechanism and a cake unloading method. Background Art

[0002] A filter press is a new type of filter that uses diaphragm extrusion to separate solids and liquids. It boasts high filtration pressure, strong material adaptability, fast cake discharge, and a high degree of automation. It is widely used in industries such as mining, metallurgy, chemicals, pharmaceuticals, and environmental engineering. The filter press primarily involves feed filtration, diaphragm extrusion, rapid cake discharge, and filter cloth cleaning. Rapid cake discharge is a crucial step in the entire filtration process, and its success impacts the filter's production capacity and operating efficiency.

[0003] The existing cake unloading method of the filter press is generally to pull the filter plates apart one by one through a transmission mechanism. The mud cake on the pulled filter plates falls off by itself due to the action of gravity. However, some mud cakes with greater viscosity often adhere to the filter plates, and workers need to use tools to pat them to unload the cakes. However, this method has high labor intensity for workers. Although some existing filter presses have the function of automatic cake unloading, automatic cake unloading generally involves shaking or rocking the filter plates to automatically separate the mud cakes. In this way, some stubborn impurities on the filter plates are not easy to fall off, resulting in incomplete shedding of the mud cakes, which affects subsequent use.

[0004] Therefore, the present invention provides a filter press cake unloading mechanism and a cake unloading method. Summary of the Invention

[0005] The purpose of this application is to solve the problems in the above-mentioned background technology, and to provide a filter press cake unloading mechanism and a cake unloading method.

[0009] A driving mechanism, acting on the toggle block and mounted on the carrier, for sequentially pushing the toggle block to move;

[0010] A scraping mechanism is installed on the carrier, and the scraping mechanism has a scraper, which is used to vertically scrape one side of the filter plate. The scraper is located in the middle of the carrier to divide the carrier into a to-be-treated area and a clean area;

[0011] The shaking mechanism is installed on the carrier and acts on the filter plate, and is used for providing the filter plate with a driving force for intermittent vertical upward and downward movement.

[0012] Furthermore, the scraping mechanism also includes two mounting frames symmetrically and horizontally slidably mounted on the carrier, and sliding plates are vertically slidably mounted on the two mounting frames. A connecting plate is installed between the tops of the two sliding plates, and the scraper is installed on the connecting plate. A touch mechanism is installed between the two mounting frames, and the touch mechanism has a sensing part. When the filter plate moves from the area to be treated to the clean area through the sensing part, the mounting frame is moved by the touch mechanism and the scraper is driven to move back and forth vertically.

[0013] Furthermore, the trigger mechanism includes:

[0014] A triggering member is installed between the two mounting frames. When the filter plate moves and touches the triggering member, the filter plate will separate from the triggering member and enter the clean area after the mounting frames move a certain distance.

[0015] A reset member, installed between the carrier and the mounting bracket, and used to reset the position of the mounting bracket after it has been moved;

[0016] A linkage mechanism is installed on the mounting frame and acts on the sliding plate. When the mounting frame moves, the sliding plate is moved back and forth vertically through the linkage mechanism.

[0017] Furthermore, the reset member includes a horizontal mounting tube installed on the carrier, a mounting rod is slidably inserted into one end of the mounting tube, the end of the mounting rod located on the outside is connected to the mounting frame, a reset spring is installed between the mounting tube and the mounting rod, and a damping block is installed at the end of the mounting tube facing the clean area.

[0018] Furthermore, the trigger member includes a rotating plate installed between the two mounting frames through a vertical rotation of the rotating shaft, a torsion spring is provided on the rotating shaft, one end of the torsion spring is connected to the mounting frame, and the other end is connected to the rotating shaft, and the torsion spring is used to form the rotating plate vertically and one side is in contact with the mounting frame, a poking plate is installed on the mounting frame for horizontal sliding, and a connecting rod is connected between the two poking plates.

[0019] Furthermore, the linkage mechanism includes a driven gear rotatably mounted on the mounting frame, a driving wheel is coaxially mounted on one side of the driven gear, a linkage is mounted between the driving wheel and the sliding plate, and a driving rack meshing with the driven gear is mounted on the carrier.

[0020] Furthermore, the linkage includes a driving plate rotatably mounted on the mounting frame at one end, a convex plate is constructed on one side of the driving plate and near the rotation point, a hinged rod is eccentrically hinged on the driving wheel, the free end of the hinged rod is hinged to the free end of the convex plate, a movable groove is opened on one side of the driving plate along its length direction, and a column rod is constructed on the sliding plate and is tangent to the movable groove.

[0021] Furthermore, the shaking mechanism includes a sliding plate horizontally slidably installed on the toggle block, a folding groove is provided on the carrier along its length direction, a driving rod is constructed on the vertical plate surface of the sliding plate, an elastic sheet is installed between the sliding plate and the toggle block to form the driving rod located in the folding groove, and an eccentric roller is eccentrically installed on the carrier.

[0022] Furthermore, the guide wheel is funnel-shaped, the cross-section of the guide rail is an isosceles trapezoidal shape, and the inclined surface of the guide rail fits the inclined surface of the guide wheel.

[0023] A filter press cake unloading method, which uses the filter press cake unloading mechanism described above, comprises the following steps:

[0024] S1: The staff rotates the eccentric roller to make multiple driving rods disengage from the folding groove, and then the filter plate moves toward the clean area through the driving mechanism. The movement of the filter plate causes the driving rod to move in the folding groove, thus forming a filter plate moving toward the clean area;

[0025] S2: The filter plate and the rotating plate rotate, thereby causing the mounting frame to move. During the movement of the mounting frame, the driven gear meshed with the driving rack rotates, thereby causing the driving plate to rotate through the hinged rod, so that the sliding plate is moved vertically back and forth through the column rod, so that the scraper scrapes the filter plate vertically back and forth for a certain period of time. When the mounting frame moves and causes the mounting rod to move to the maximum limit position, the filter plate passes through the rotating plate and enters the clean area. At this time, the rotating scraper is reset to the vertical direction due to the torsion spring, and the mounting frame is reset due to the reset spring, and so on.

[0026] S3: Rotate the eccentric roller to disengage the plurality of driving rods from the folding groove, then move the poking plate to rotate the rotating plate to a horizontal position, and then move the filter plate in the clean area to the area to be processed.

[0027] The beneficial effects of this application are as follows:

[0028] 1. Compared with the prior art, the present application not only performs preliminary cleaning of the mud cake on the filter plate through the shaking mechanism, but also subsequently uses the scraper to scrape off the stubborn impurities on the filter plate, thereby improving the mud cake treatment effect on the filter plate and preventing the filter plate from being not cleaned properly and affecting subsequent use.

[0029] 2. The present application uses a driving rod in conjunction with a folding groove design to allow the filter plate to move while shaking up and down, thereby shaking off the mud cake on the filter plate as it moves toward the clean area, thereby reducing the time for shaking the filter plate and further improving the cake unloading efficiency.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like Figures 1-8 As shown, a filter press cake unloading mechanism proposed in one embodiment of the present application includes:

[0041] The carrier 1 has two guide rails 2 symmetrically mounted horizontally thereon, and also includes a plurality of filter plates 3. A toggle block 4 is constructed on both sides of the filter plates 3. The toggle block 4 is rotatably mounted with a guide wheel 5 placed on the guide rails 2, that is, the guide wheel 5 can roll along the guide rails 2;

[0042] The driving mechanism 6 acts on the toggle block 4 and is mounted on the carrier 1. The driving mechanism 6 is used to sequentially push the toggle block 4 to move. In other words, the driving mechanism 6 can sequentially push the filter plate 3 to move.

[0043] The scraping mechanism 7 is installed on the carrier 1. The scraping mechanism 7 has a scraper 701, which is used to scrape one side of the filter plate 3 vertically. The scraper 701 is located in the middle of the carrier 1 to divide the carrier 1 into a waiting area 702 and a clean area 703. When the filter press is in working condition, multiple filter plates 3 are located in the waiting area 702. The filter plates 3 located in the waiting area 702 can be moved to the clean area 703 in sequence by the driving mechanism 6. In this embodiment, it can be consistent with the method of driving the filter plates 3 in the existing filter press. The existing filter press drives the movement of multiple filter plates 3 in sequence by sliding the pull plate trolley installed thereon. When the filter plate 3 moves under the scraper 701, the scraper 701 moves downward to scrape one side of the filter plate 3, thereby scraping the mud cake from the filter plate 3. Then the filter cake continues to move to the clean area 703, which is convenient for the staff to intuitively distinguish which are the cleaned filter plates 3;

[0044] The shaking mechanism 8 is installed on the carrier 1 and acts on the filter plate 3. It is used to provide the filter plate 3 with an intermittent driving force for vertical upward and downward movement. That is to say, the filter plate 3 can be shaken up and down by the shaking mechanism 8, so as to shake off the filter cake on the filter plate 3. At this time, some impurities with large adhesion may remain on the filter plate 3, which can be scraped off by the scraper 701, thereby improving the cleaning effect of the filter cake on the filter plate 3.

[0045] After that, the filter cake on filter plate 3 needs to be cleaned, first, the filter plate 3 closest to the clean area 703 is moved by driving mechanism 6. When filter plate 3 moves below scraper 701, the filter plate 3 is moved back and forth vertically by shaking mechanism 8, and the mud cake on filter plate 3 is shaken off. Then scraper 701 moves downward to remove the stubborn impurities on filter plate 3, thereby completing cake unloading. After that, the cleaned filter plate 3 is moved into the clean area 703 by driving mechanism 6, and then the driving mechanism 6 drives another filter plate 3 in the treatment area 702 to be cleaned, and so on, thereby realizing cleaning of the filter cake on filter plate 3. Compared with the prior art, not only the mud cake on filter plate 3 is preliminarily cleaned by shaking mechanism 8, but also the stubborn impurities on filter plate 3 can be scraped and processed subsequently by scraper 701, thereby improving the mud cake processing effect on filter plate 3 and preventing filter plate 3 from being not cleaned in place and affecting subsequent use.

[0046] like Figure 3 、 Figure 5 and Figure 7 As shown, in some embodiments, the scraping mechanism 7 further includes two mounting frames 704 symmetrically and horizontally slidably mounted on the carrier 1, and a sliding plate 705 is vertically slidably mounted on the two mounting frames 704, a connecting plate 706 is installed between the tops of the two sliding plates 705, and the scraper 701 is installed on the connecting plate 706. A touch mechanism is installed between the two mounting frames 704, and the touch mechanism has a sensing part. When the filter plate 3 moves from the area to be treated 702 to the clean area 703 through the sensing part, the mounting frame 704 is moved by the touch mechanism and the scraper 701 is driven to move vertically back and forth. That is to say, when the filter plate 3 in the area to be treated 702 moves to the clean area 703, at this time The filter plate 3 will come into contact with the sensing part, so that the continued movement of the filter plate 3 and the triggering mechanism will cause the mounting frame 704 to move. During the movement of the mounting frame 704, the scraper 701 will also move back and forth vertically, thereby scraping the filter plate 3. The way in which the scraper 701 scrapes the filter plate 3 vertically and reciprocally can not only improve the cleaning effect of the filter plate 3, but also the impurities adhered to the scraper 701 during the scraping are easily shaken off due to the vertical reciprocating movement of the scraper 701, thereby preventing the scraper 701 from adhering to a lot of dirt after working for a period of time. The cleaned filter plate 3 continues to move until it passes through the sensing part, thereby allowing the cleaned filter plate 3 to move to the clean area 703.

[0047] like Figure 1-Figure 7 As shown, in some embodiments, the trigger mechanism includes:

[0048] The trigger member 9 is installed between the two mounting brackets 704. When the filter plate 3 moves to touch the trigger member 9, the mounting bracket 704 moves a certain distance, and then the filter plate 3 separates from the trigger member 9 and enters the clean area 703.

[0049] A reset member 11 is installed between the carrier 1 and the mounting bracket 704 and is used to reset the position of the mounting bracket 704 after it has moved;

[0050] The linkage mechanism 12 is installed on the mounting frame 704 and acts on the sliding plate 705. When the mounting frame 704 moves, the sliding plate 705 is moved back and forth vertically through the linkage mechanism 12. That is to say, when the filter plate 3 that needs to be cleaned moves toward the clean area 703, the filter plate 3 will first contact the trigger member 9, so that the trigger member 9 will move a distance with the movement of the filter plate 3. Because the trigger member 9 is installed between the two mounting frames 704, the mounting frame 704 will also move accordingly. During the movement of the mounting frame 704, the sliding plate 705 is moved back and forth vertically through the linkage mechanism 12. Because the two sliding plates 705 are connected to the connecting plate 706, and the connecting plate 706 is connected to the scraper 701, the sliding plate 705 moves back and forth vertically indirectly. The movable scraper 701 moves back and forth vertically, and the mounting frame 704 moves to a certain distance with the trigger member 9. At this time, the filter plate 3 will separate from the trigger member 9 and enter the clean area 703. The filter plate 3 is already in a clean state. At this time, the resetting member 11 will reset the position of the mounting frame 704, thereby indirectly resetting the position of the trigger member 9, so that the scraper 701 is in the initial state (the initial state of the scraper 701 is the highest limit position of the scraper 701 movement), so as not to affect the next filter plate 3 passing through the scraper 701 and contacting the trigger member 9. The trigger member 9 here plays a limiting role. When the filter plate 3 contacts the trigger member 9, the scraper 701 at this time can scrape one side of the filter plate 3 when it moves back and forth vertically, thereby cleaning the stubborn impurities in the filter plate 3.

[0051] like Figure 1 and Figure 5As shown, in some embodiments, the reset member 11 includes a horizontal mounting cylinder 1101 mounted on the carrier 1, a mounting rod 1102 is slidably inserted into one end of the mounting cylinder 1101, the outer end of the mounting rod 1102 is connected to the mounting frame 704, a reset spring 1103 is installed between the mounting cylinder 1101 and the mounting rod 1102, and a damping block 1104 is installed at the end of the mounting cylinder 1101 facing the clean area 703. When the mounting frame 704 is moving, because the mounting frame 704 is connected to the mounting rod 1102, the movement of the mounting frame 704 will drive the mounting rod 1102 to move. During the movement, the mounting rod 1102 pulls the reset spring 1103 so that the reset spring 1103 is stretched. When the mounting rod 1102 moves to the maximum limit position When the filter plate 3 is released, the filter plate 3 is reset due to the elastic deformation of the reset spring 1103, causing the mounting rod 1102 to retract, thereby indirectly driving the mounting bracket 704 to move backward, thereby causing the mounting bracket 704 to contact the damping block 1104. The design of the damping block 1104 allows the mounting bracket 704 to have a buffering effect when it retracts, preventing the mounting bracket 704 from being damaged by a large impact when it is reset, thereby playing a protective role. Specifically, the end of the mounting rod 1102 located inside the mounting cylinder 1101 is constructed with a stopper that fits against the inner circumferential wall of the mounting cylinder 1101. The stopper is connected to the reset spring 1103, which plays a limiting role, preventing the mounting rod 1102 from sliding out of the mounting cylinder 1101.

[0052] like Figure 1 and Figure 6As shown, in some embodiments, the trigger member 9 includes a rotating plate 901 installed between the two mounting brackets 704 through a vertical rotation of the rotating shaft, the sensing part is the rotating plate 901, and a torsion spring 902 is sleeved on the rotating shaft, one end of the torsion spring 902 is connected to the mounting bracket 704, and the other end is connected to the rotating shaft, through the torsion spring 902 to form the rotating plate 901 vertically and one side is in contact with the mounting bracket 704, specifically, the elastic force of the torsion spring 902 is greater than the elastic force of the return spring 1103, and a poking plate 903 is installed on the mounting bracket 704 for horizontal sliding, and a connecting rod 904 is connected between the two poking plates 903. When the filter plate 3 moves and contacts the rotating plate 901, because the elastic force of the torsion spring 902 is greater than the elastic force of the return spring 1103, the rotating plate 901 will not rotate, so that the movement of the filter plate 3 will drive the rotating plate 901 to move horizontally, so as to Then it drives the mounting frame 704 to move. When the mounting rod 1102 moves to the maximum limit position, the filter plate 3 continues to move, thereby forcing the rotating plate 901 to rotate until it passes through the rotating plate 901. At this time, the torsion spring 902 will reset due to its own elastic deformation characteristics, causing the rotating plate 901 to rotate to a vertical direction and conflict with the mounting frame 704. The design of the poking plate 903 allows the filter plate 3 in the clean area 703 to be moved to the treatment area 702 by moving the poking plate 903 so that the poking plate 903 pokes the rotating plate 901 so that the rotating plate 901 is horizontal, so that the filter plate 3 in the clean area 703 can directly pass through the rotating plate 901, which is convenient for resetting the filter plate 3 later. Preferably, a hydraulic cylinder can be installed on the mounting frame 704, and the movable end of the hydraulic cylinder is connected to the connecting rod 904, so as to facilitate the control of the state of the filter plate 3.

[0053] like Figure 1 and Figure 5As shown, in some embodiments, the linkage mechanism 12 includes a driven gear 1201 rotatably mounted on the mounting frame 704, a driving wheel 1202 is coaxially mounted on one side of the driven gear 1201, a linkage member 10 is installed between the driving wheel 1202 and the sliding plate 705, and a driving rack 1203 engaged with the driven gear 1201 is installed on the carrier 1. That is, when the filter plate 3 moves and contacts the rotating plate 901 so that the mounting frame 704 moves, because the driven gear 1201 is rotatably mounted on the mounting frame 704 and the driven gear 1201 is engaged with the driving rack installed on the carrier 1 1203 is engaged, so when the mounting frame 704 is moving, the driven gear 1201 will rotate, thereby causing the driving wheel 1202 to rotate. During the continuous rotation of the driving wheel 1202, the sliding plate 705 will move vertically back and forth through the connecting member 10, so that when the filter plate 3 moves from the treatment area 702 to the clean area 703, the filter plate 3 does not need to stop moving in the middle to allow the scraper 701 to scrape the filter plate 3. After the filter plate 3 hits the rotating plate 901, the scraper 701 moves while scraping one side of the filter plate 3, thereby saving time and improving the cake unloading efficiency.

[0054] like Figure 1-Figure 7As shown, in some embodiments, the linkage 10 includes a driving plate 1001 rotatably mounted on a mounting frame 704 at one end, a convex plate 1002 is constructed on one side of the driving plate 1001 and near the rotation point, a hinge rod 1003 is eccentrically hinged on the driving wheel 1202, and the free end of the hinge rod 1003 is hinged to the free end of the convex plate 1002, a movable groove 1004 is opened on one side of the driving plate 1001 along its length direction, and a column rod 1005 is constructed on the sliding plate 705 that slides tangentially with the movable groove 1004. When the mounting frame 704 moves to make the driving wheel During the continuous rotation of 1202, the driving wheel 1202 rotates to drive the hinge rod 1003 eccentrically hinged thereon to move. Because the other end of the hinge rod 1003 is hinged on the convex plate 1002, and the convex plate 1002 is constructed on the driving plate 1001, the driving wheel 1202 rotates through the hinge rod 1003 to make the driving plate 1001 move back and forth. Because the column 1005 on the sliding plate 705 slides tangentially with the movable groove 1004 on the driving plate 1001, when the driving plate 1001 rotates, the column 1005 on the sliding plate 705 is tangential to the movable groove 1004 on the driving plate 1001. The rod 1005 moves along the length direction of the movable groove 1004 and rotates along its own axis, thereby indirectly driving the sliding plate 705 to move back and forth vertically, so as to realize the reciprocating movement of the scraper 701 to scrape one side of the filter plate 3. It should be noted that after the mounting bracket 704 is reset, the scraper 701 is at the position of the highest limit distance, which does not affect the next filter plate 3 passing through the scraper 701 and contacting the rotating plate 901. Preferably, the teeth of the driven gear 1201 and the driving rack 1203 can be closer, so that the mounting bracket 704 can move as much as possible within a certain moving distance. The driving wheel 1202 may rotate more circles, thereby indirectly improving the scraping effect, and can also effectively prevent the scraper 701 from adhering to impurities. The convex plate 1002 is close to the rotation point of the driving plate 1001, so that when the driving wheel 1202 rotates, the driving plate 1001 reciprocates at a larger angle, so that when the sliding plate 705 moves vertically, it can not only scrape the entire surface of the filter plate 3, but also ensure that the scraper 701 has a stroke to move above the filter plate 3 when it is reset, thereby achieving the purpose of increasing the moving stroke of the scraper 701.

[0055] like Figure 6-Figure 7As shown, in some embodiments, the shaking mechanism 8 includes a sliding plate 801 horizontally slidably mounted on the toggle block 4, a folding groove 802 is opened on the carrier 1 along its length direction, a driving rod 803 is constructed on the vertical plate surface of the sliding plate 801, an elastic sheet 804 is installed between the sliding plate 801 and the toggle block 4 to form a driving rod 803 located in the folding groove 802, and an eccentric roller 805 is eccentrically installed on the carrier 1. That is to say, when it is necessary to move the filter plate 3 located in the clean area 703 to the to-be-treated area 702, the eccentric roller 805 can be rotated so that the eccentric roller 805 contacts the vertical plate surface of the sliding plate 801, so that the sliding plate 705 moves in a direction away from the folding groove 802, thereby making multiple driving The movable rod 803 is out of the folding groove 802. When the filter plate 3 located in the treatment area 702 needs to be cleaned, the eccentric roller 805 is rotated so that the eccentric roller 805 does not contact the sliding plate 801, thereby making the driving rod 803 located in the folding groove 802 through the elastic sheet 804. In this way, when the filter plate 3 moves, the driving rod 803 will move along the guidance of the folding groove 802, and when the driving rod 803 moves upward at an angle, the filter plate 3 will be lifted up. When the driving rod 803 moves from bottom to top, the filter plate 3 will move downward again, so that the filter plate 3 will shake up and down while moving, thereby shaking off the mud cake on the filter plate 3 on the way to the clean area 703, thereby reducing the time of shaking the filter plate 3 and further improving the cake unloading efficiency.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments, the guide wheel 5 is funnel-shaped, the cross-section of the guide rail 2 is an isosceles trapezoidal shape, and the inclined surface of the guide rail 2 fits the inclined surface of the guide wheel 5, so that when the filter plate 3 shakes up and down, the guide wheel 5 is not easy to slide out of the guide rail 2, thereby ensuring the smoothness of the movement of the filter plate 3.

[0057] A filter press cake unloading method, which uses the filter press cake unloading mechanism described above, comprises the following steps:

[0058] S1: The staff rotates the eccentric roller 805 to disengage the multiple driving rods 803 from the folding groove 802, and then the filter plate 3 moves toward the clean area 703 through the driving mechanism 6. The movement of the filter plate 3 causes the driving rods 803 to move in the folding groove 802, thereby forming a filter plate 3 moving toward the clean area 703;

[0059] S2: The filter plate 3 and the rotating plate 901 rotate, thereby moving the mounting frame 704. During the movement, the mounting frame 704 rotates the driven gear 1201 meshing with the driving rack 1203, thereby rotating the driving plate 1001 through the hinged rod 1003, so that the sliding plate 705 moves vertically back and forth through the column 1005, so that the scraper 701 scrapes the filter plate 3 vertically back and forth. When the mounting frame 704 moves and the mounting rod 1102 moves to the maximum limit position, the filter plate 3 passes through the rotating plate 901 and enters the clean area 703. At this time, the rotating scraper 701 is reset to the vertical direction due to the torsion spring 902, and the mounting frame 704 is reset due to the reset spring 1103, and so on.

[0060] S3: Rotate the eccentric roller 805 to disengage the plurality of driving rods 803 from the folding groove 802 , then move the poking plate 903 to rotate the rotating plate 901 to a horizontal position, and then move the filter plate 3 in the clean area 703 to the area to be processed 702 .
