[0028] Embodiment 1

[0029] See also Figures 1 to 6 The present embodiment relates to a filter plate supporting mechanism, which includes a supporting body 1 for connecting a filter plate 27. A mounting portion is formed on one side of the supporting body 1.

[0030] A rotatable rolling body 2 is arranged at the bottom of the support body 1. The rolling body 2 is used to roll in contact with the top end surface of the main beam 26a of the filter press when the support body 1 supports the filter plate 27, so as to reduce the friction resistance between the support body 1 and the main beam 26a of the filter press when the filter plate 27 moves, thereby ensuring that the filter plate 27 can move smoothly and reducing the wear of the main beam 26a of the filter press.

[0031] A liquid storage chamber for accommodating lubricating liquid and a flow channel connected to the liquid storage chamber for flowing liquid are formed inside the support body 1; a liquid filling port 3 connected to the liquid storage chamber is provided at the top of the support body 1; the end of the flow channel is connected to the bottom end of the support body 1 and forms a lubrication hole 4; the lubricating liquid enters the liquid storage chamber through the liquid filling port 3, flows along the flow channel, and lubricates the rolling element 2 through the lubrication hole 4, so as to replace manual application of lubricating liquid, thereby reducing labor intensity.

[0032] A piston component that can absorb and discharge pressurized lubricating liquid is arranged in the support body 1, and the piston component is connected to the rolling body 2 through a transmission component; when the filter plate 27 moves, the support body 1 moves along the main beam 26a of the filter press, driving the rolling body 2 on the support body 1 to rotate accordingly, and through the transmission of the transmission component, the piston component is driven to absorb the lubricating liquid in the liquid storage chamber for pressurization, and discharge the pressurized lubricating liquid toward the lubrication hole 4 to promote the transportation of the lubricating liquid and lubricate the rolling body 2 in time; when the filter plate 27 is stationary, the support body 1 is stationary accordingly, the rolling body 2 stops rotating, and the piston component stops absorbing and discharging the pressurized lubricating liquid to avoid the lubricating liquid flowing out of the lubrication hole 4 when the support body 1 is stationary, causing waste.

[0033] Specifically, the support body 1 is a support plate in the shape of a right triangle, the vertical side of the support body 1 is a mounting portion, the support body 1 is fixedly connected to the frame 27a of the filter plate 27 by bolts, and the support body 1 is provided with corresponding bolt holes on the mounting portion; the horizontal side of the support body 1 is the bottom of the support body 1, the support body 1 is provided with a mounting groove 5 at the bottom, and the mounting groove 5 forms a notch on the bottom side; the rolling body 2 is rotatably installed in the mounting groove 5, and the outer peripheral surface of the rolling body 2 can be rotated to the outside of the bottom side notch of the mounting groove 5 to roll and abut against the top end surface of the main beam 26a of the filter press; the lubrication hole 4 is provided on the top side of the mounting groove 5 to facilitate lubrication of the outer peripheral surface of the rolling body 2 rotated to the top side of the mounting groove 5.

[0034] It should be noted that in this embodiment, the support body 1 is a support plate in the shape of a right triangle, which can form a triangular support structure to facilitate stably supporting the filter plate 27 on the main beam 26a of the filter press; according to actual needs, the support body 1 can also be replaced by support plates of other shapes.

[0035] The support plate has a first plate surface and a second plate surface. The first plate surface of the support plate is provided with a first groove 6 and a second groove 7 located below the first groove 6. The first groove 6 and the second groove 7 both have a groove bottom wall and annular groove side walls, and the groove openings of the two grooves are opposite to the groove bottom wall; the flow channel sequentially connects the first groove 6, the second groove 7 and the lubrication hole 4.

[0036] The support plate is detachably provided with a first slot cover 8 at the slot opening of the first slot 6, and the first slot cover 8 seals the first slot 6 to form a liquid storage chamber; by removing the first slot cover 8, it is convenient to pour out the residual lubricating liquid and clean the dirt deposited inside the first slot 6 during maintenance; the first slot cover 8 is made of transparent material, so as to observe the remaining lubricating liquid in the liquid storage chamber; a first sealing ring 9 is provided between the first slot cover 8 and the slot opening of the first slot 6, and the first sealing ring 9 is used to seal the gap between the first slot cover 8 and the slot opening of the first slot 6 to prevent the lubricating liquid from flowing out of the gap; a liquid filling port 3 connected to the first slot 6 is provided on the top of the support plate, the starting end of the flow channel is connected to the first slot 6, and a liquid supply hole is opened on the side wall of the slot of the first slot 6.

[0037] The support plate is detachably covered with a second slot cover 10 at the slot opening of the second slot 7, and the second slot cover 10 seals the second slot 7; a first liquid hole 11 and a second liquid hole 12 are opened on the slot side wall of the second slot 7, the liquid supply hole of the first slot 6 is connected with the first liquid hole 11 of the second slot 7 through a flow channel, and the second liquid hole 12 of the second slot 7 is connected with the lubrication hole 4 on the support plate through the flow channel; the piston component is movably installed in the second slot 7 through the slot opening of the second slot 7 to suck the lubricating liquid from the first liquid hole 11 into the second slot 7, and after the piston component is added, it is discharged from the second slot 7 from the second liquid hole 12; by removing the second slot cover 10, it is convenient to pour out the residual lubricating liquid during maintenance, and remove the piston component for cleaning; a second sealing ring 13 is arranged between the second slot cover 10 and the slot opening of the second slot 7, and the second sealing ring 13 is used to seal the gap between the second slot cover 10 and the slot opening of the second slot 7 to prevent the lubricating liquid from flowing out of the gap.

[0038] A third groove 14 is provided on the second plate surface of the support plate, and the notch of the third groove 14 is opposite to the bottom wall of the groove; the support plate is detachably covered with a third groove cover 15 at the notch of the third groove 14, and the third groove cover 15 seals the third groove 14 to form a transmission chamber, and the transmission component is movably installed in the third groove 14 through the notch of the third groove 14, and the piston component and the rolling body 2 are connected to each other in transmission; by removing the third groove cover 15, the transmission component can be removed for cleaning during maintenance.

[0039] The third groove 14 has a groove bottom wall and an annular groove side wall. The groove bottom wall of the third groove 14 is provided with a first transmission channel 16 for connecting with the second groove 7, and a second transmission channel 17 for connecting with the bottom mounting groove 5 of the support plate, so that the transmission component is connected to the piston component through the first transmission channel 16, and the transmission component is connected to the rolling body 2 through the second transmission channel 17.

[0040] The piston component includes a crankshaft 18 rotatably inserted in the first transmission channel 16, and a rotor 19 sleeved on the crank portion of the crankshaft 18 and rotatable along the groove side wall in the second groove 7. A guide groove 20 connected to the second groove 7 is provided on one side of the groove side wall of the second groove 7. A slide 21 is movably installed in the guide groove 20. One end of the slide 21 can extend into the second groove 7 to abut the outer circumferential surface of the rotor 19. A spring 22 is connected between the other end of the slide 21 and the groove wall of the guide groove 20. Under the elastic force of the spring 22, the slide 21 is tightly attached to the rotor 19, so that the internal space of the sealed second groove 7 is divided into a liquid suction chamber and a pressurizing chamber. The first liquid through hole 11 is connected to the liquid suction chamber, and the second liquid through hole 12 is connected to the pressurizing chamber. When the crankshaft 18 rotates, the rotor 19 is driven to rotate accordingly. The slide 21 performs a linear reciprocating motion in the guide groove 20 with the rotation of the rotor 19 and under the action of the spring 22, so as to complete the liquid suction-pressurizing-discharging.

[0041] Since the internal space of the second groove 7 is in a vacuum state after being closed, when the rotor 19 rotates, the pressure in the boost chamber of the second groove 7 is greater than the external pressure of the second groove 7, so that the lubricating fluid is discharged, and the rotation of the rolling body 2 is used as a power source, without the need to additionally set up a driving device to provide power, thereby simplifying the structure and reducing the manufacturing cost; when the rotor 19 is stationary, the pressure in the boost chamber of the second groove 7 is less than the external pressure of the second groove 7, and the lubricating fluid stops flowing, thereby preventing the lubricating fluid from flowing out of the lubrication hole 4 when the support plate is stationary, without the need to additionally set up a valve device to close the flow channel, further simplifying the structure.

[0042] A bearing (not shown in the figure) and a third sealing ring 23 for sealing the first transmission channel 16 are arranged in the first transmission channel 16, and the bearing is sleeved on the crankshaft 18 to ensure smooth rotation of the crankshaft 18; two third sealing rings 23 are provided and sleeved on the crankshaft 18, and the gap between the bottom of the second groove 7 and the crankshaft 18 and the gap between the bottom wall of the third groove 14 and the crankshaft 18 are respectively sealed by the two third sealing rings 23 to prevent the lubricating fluid from flowing out of the gap.

[0043] It should be noted that, in the present embodiment, the first sealing ring 9, the second sealing ring 13 and the third sealing ring 23 are all rubber sealing rings, and the sizes of the sealing rings are selected according to actual needs.

[0044] The transmission component includes a worm gear 24 and a pot rod 25 that are arranged in the third groove 14 and mesh with each other. The worm gear 24 is fixedly mounted on the crankshaft 18, and one end of the pot rod 25 penetrates into the bottom mounting groove 5 of the support plate through the second transmission channel 17 to connect with the rolling body 2; when the rolling body 2 rotates, the crankshaft 18 is driven to rotate through the worm gear and pot rod transmission, and the rotor 19 rotates accordingly, and the slide 21 follows the rotor 19 to reciprocate in the guide groove 20, so that the lubricating liquid can be sucked and discharged during the movement of the support plate; because the worm gear and pot rod transmission used in this embodiment has a self-locking effect, when the rolling body 2 is stationary, the pot rod 25 stops rotating, and the worm gear 24 can remain stationary, so that the rotor 19 is correspondingly stationary, thereby limiting the outflow of the lubricating liquid.

[0045] It should be noted that the transmission component in this embodiment adopts worm gear transmission. According to actual needs, other transmission components that can self-lock when the rolling body 2 is stationary can also be used instead.

[0046] The rolling body 2 is a roller of cylindrical structure, which can be rotatably installed in the bottom mounting groove 5 of the support plate, and the outer peripheral surface of the roller can be rotated to the outside of the bottom side notch of the mounting groove 5 to make line contact with the top end surface of the main beam 26a of the filter press to increase the stability of the support plate when moving; the outer peripheral surface of the roller is wrapped with a rubber layer to reduce vibration and reduce noise.

[0047] In this embodiment, a plurality of lubrication holes 4 are provided, and the plurality of lubrication holes 4 are evenly spaced along the length direction of the bottom mounting groove 5 of the support plate, so as to evenly apply the lubricating liquid on the roller.

[0048] The lubricating liquid in this embodiment is lubricating oil, and other liquid lubricating liquids may be used instead according to actual conditions.

[0049] Embodiment 2

[0050] See also Figure 7 The present embodiment relates to a plate and frame filter press, which includes a filter press body 26 and a plurality of filter plates 27. An elongated main beam 26a is mounted on the filter press body 26. Each filter plate 27 includes a frame 27a and a filter element 27b mounted on the frame 27a. The filter plate supporting mechanism of the first embodiment is mounted on both sides of the frame 27a. The filter plate 27 is supported on the main beam 26a by the filter plate supporting mechanism and can move along the main beam 26a. When the filter plate 27 moves, the filter plate supporting mechanism can release lubricating fluid to reduce the moving friction resistance generated between the filter plate 27 and the main beam 26a, thereby ensuring smooth movement. When the filter plate 27 is stationary, the filter plate supporting mechanism can stop releasing lubricating fluid to avoid wasting lubricating fluid.
