Description

Technical Field

[0001] The invention relates to the technical field of filter presses, in particular to a filter press unit which is convenient for discharging materials. Background Art

[0002] ‌Filter press is a solid-liquid separation equipment. It achieves solid-liquid separation by applying pressure to make liquid pass through the filter medium while solid particles are retained. It is widely used in chemical, pharmaceutical, metallurgical and other industries. The working principle of filter press is based on surface filtration. During operation, the hydraulic cylinder presses all filter plates tightly to form a closed filter chamber. The slurry enters the filter plate through the filter plate feed hole with a certain pressure. The solid particles are retained by the filter plate to form a filter cake, and the liquid is discharged through the filter plate.

[0003] At present, when some filter presses are in use, the filter cake is placed between two adjacent filter plates. The staff needs to use a plate puller to separate the two adjacent filter plates in turn and clean the filter cake on the surface of the filter plates regularly. During this process, the staff needs to use tools to scrape the filter cake on the surface of each filter plate in turn. This process is time-consuming and labor-intensive, and when the staff uses tools to scrape and clean the filter cake, the tools used by the staff are prone to collide with the surface of the filter plate and affect the filter cloth on the surface of the filter plate, thereby affecting the normal progress of subsequent filtration operations.

The force-applying mechanism, the knocking mechanism and the force-bearing plate can cooperate to repeatedly knock on the top of the filter plate. The connection mechanism, the pulley and the pull rope can cooperate with the lifting mechanism to drive the elastic rope to lift so as to scrape the bottom of the filter cake. This solves the problem that when some filter presses are currently in use, the staff use a plate puller and tools to unload the filter cake, which is not only time-consuming and labor-intensive, but also the tools are prone to collide with the filter plate and affect the normal subsequent filtration operation.

The surfaces of the thin rod 16 and the slider 18 are in contact with the inner wall of the card plate 17. The coordinated use of the card plate 17, the slider 18 and the thin rod 16 can increase the stability of the thin rod 16 when moving.

[0020] The lifting mechanism 13 includes a lifting plate 131, a rectangular frame 132 and an extrusion plate 133. There are four lifting plates 131. The four lifting plates 131 are respectively threadedly sleeved on the surfaces of the two first screw rods 7 and the two second screw rods 8. The rectangular frame 132 is fixedly connected to the surface of the lifting plate 131. The surface of the lifting plate 131 is slidably connected to the inner wall of the fixing frame 6. The extrusion plate 133 is slidably connected to the bottom of the rectangular frame 132. The top of the extrusion plate 133 is fixedly connected with a T-shaped plate 14. The surface of the T-shaped plate 14 is slidably connected to the inner wall of the rectangular frame 132. The four lifting plates 131 can rotate simultaneously when the second screw rod 8 and the first screw rod 7 rotate. The lifting plate 131 can drive the rectangular frame 132 to descend. The extrusion plate 133 descends accordingly to squeeze the extension plate 3 so that the filter plate 2 can move, thereby facilitating the unloading of the filter cake. In this process, the T-shaped plate 14 can increase the stability of the extrusion plate 133 when it moves. The lifting plate 131 drives the rectangular frame 132 to descend, and the extrusion plate 133 descends accordingly. At this time, when the extrusion plate 133 in contact with the extension plate 3 descends, the inclined surface of the extrusion plate 133 can push the extension plate 3, and the extension plate 3 can drive the filter plate 2 to move. In this process, when the extension plate 3 moves, the extrusion plate 133 can be affected by the movement of the extension plate 3 and move laterally. At this time, the T-shaped plate 14 can guide the movement of the extrusion plate 133. The schematic diagram of the lifting mechanism 13 adjusting the position of the extension plate 3 and the filter plate 2 is shown in Fig.11 shown.

[0021] The reset mechanism 15 includes a thin plate 151, a polished rod 152, a reset plate 153 and a first tension spring 154. The thin plate 151 is fixedly connected to the surface of the fixing frame 6, the polished rod 152 is fixedly connected to the surface of the thin plate 151, the reset plate 153 is slidably sleeved on the surface of the polished rod 152, the reset plate 153 is fixedly connected to the surface of the extension plate 3, the number of the first tension springs 154 and the reset plates 153 are both several, and the two ends of the first tension spring 154 are respectively fixedly connected to the surfaces of two adjacent reset plates 153. When the extrusion plate 133 descends, it squeezes the extension plate 3 so as to expand the distance between the two adjacent extension plates 3. At this time, the distance between the two adjacent filter plates 2 increases so that the filter cake can fall smoothly. Thereafter, under the action of the elastic force of the first tension spring 154, the two adjacent reset plates 153 move toward opposite sides, and the extension plate 3 can drive the filter plate 2 to move and reset for subsequent use.

[0022] The connecting mechanism 19 includes a connecting plate 191, a supporting plate 192 and a limiting plate 193. The connecting plate 191 is slidably sleeved on the surface of the thin rod 16, the elastic rope 22 is fixedly connected to the surface of the connecting plate 191, a limiting groove is provided on the surface of the fixing frame 6, the surface of the limiting plate 193 is connected to the inner wall sliding rod of the limiting groove, the supporting plate 192 is fixedly connected to the surface of the limiting plate 193, the surface of the supporting plate 192 is slidably connected to the surface of the fixing frame 6, the bottom of the connecting plate 191 is slidably connected to the top of the supporting plate 192, when the lifting plate 131 descends, the pull rope 21 pulls the limiting plate 193, and the support plate 192 drives the connecting plate 191 to rise, and at this time the elastic rope 22 rises to scrape the filter cake on the surface of the filter plate 2, thereby assisting in the discharge of the filter cake.

[0023] The surface of the pull rope 21 contacts the surface of the pulley 20. When the lifting mechanism 13 moves, the pull rope 21 can move with it. At this time, the pulley 20 can guide the pull rope 21. The pulley 20 assists the movement of the pull rope 21 to increase the smoothness of the pull rope 21 when it moves, so that the pull rope 21 can drive the connecting mechanism 19 to move up and down as the lifting mechanism 13 moves.

[0024] The auxiliary mechanism 23 includes a vertical plate 231, a bottom plate 232 and an auxiliary plate 233. The vertical plate 231 is fixedly connected to the bottom of the filter plate 2, the bottom plate 232 is fixedly connected to the bottom of the vertical plate 231, and the auxiliary plate 233 is fixedly connected to the top of the bottom plate 232. The auxiliary plate 233 is inclined in design. The surface of the elastic rope 22 is in contact with the surfaces of the bottom plate 232 and the auxiliary plate 233. When the elastic rope 22 is idle, the bottom plate 232 can limit the position of the elastic rope 22. When the elastic rope 22 moves, the auxiliary plate 233 can assist in guiding the elastic rope 22. The elastic rope 22 fits with the surface of the filter plate 2 during the movement, so that the elastic rope 22 can scrape the bottom of the filter cake on the surface of the filter plate 2 to assist in the discharge of the filter cake.

[0025] The force-applying assembly 261 includes a long rod 2611, a cam 2612 and a bevel gear 2613. The long rod 2611 rotates and penetrates the side plate 25. The cam 2612 is fixedly sleeved on the surface of the long rod 2611. The bevel gear 2613 is fixedly connected to one end of the long rod 2611. The surface of the cam 2612 contacts the top of the force-bearing plate 29. When the long rod 2611 rotates, the cam 2612 rotates accordingly to press the force-bearing plate 29 back and forth, so that the knocking mechanism 28 can move back and forth and knock on the bottom of the filter plate 2, thereby driving the filter cake to be discharged through vibration. The adjusting assembly 262 includes an adjusting rod 2621, a second belt pulley 2622 and a bevel gear pulley 2623. The rod 2621 rotates and passes through the top of the cross plate 24. There are two second belt pulleys 2622. The two second belt pulleys 2622 are respectively fixedly mounted on the adjusting rod 2621 and the surface of the second screw rod 8 on one side. The two second belt pulleys 2622 are connected by belt transmission. The bevel gear plate 2623 is fixedly connected to the top of the adjusting rod 2621. The bevel gear plate 2623 is meshed with the bevel gear 2613. When the second screw rod 8 rotates, it can drive the second belt pulley 2622 to rotate. At this time, the adjusting rod 2621 rotates accordingly to drive the bevel gear plate 2623 to rotate. When the bevel gear plate 2623 rotates, it can drive the bevel gear 2613 to rotate, thereby driving the long rod 2611 to rotate.

[0026] The knocking mechanism 28 includes a thick plate 281, a knocking plate 282, an anti-slip rod 283 and a second tension spring 284. The thick plate 281 slides through the top of the cover plate 27, the knocking plate 282 is fixedly connected to the bottom of the thick plate 281, the anti-slip rod 283 is fixedly connected to the top of the knocking plate 282, the second tension spring 284 is sleeved on the surface of the anti-slip rod 283, and the force plate 29 is fixedly connected to the top of the thick plate 281. When the cam 2612 rotates and presses the force plate 29, the force plate 29 can drive the thick plate 281 to descend. At this time, the knocking plate 282 will descend accordingly and can knock on the top of the filter plate 2, so as to assist the filter cake on the surface of the filter plate 2 to fall by vibration. Thereafter, under the action of the elastic force of the second tension spring 284, the knocking plate 282 can be lifted and reset.

[0027] Working principle: when the hydraulic cylinder 4 is started and drives the push plate 5 to move, the push plate 5 pushes the filter plate 2 so that several filter plates 2 can fit together, and the slurry can be filtered when passing through the filter plate 2. The solid particles generated during the filtration process accumulate on the surface of the filter plate 2 and form a filter cake. After the filtration operation is completed, the staff starts the hydraulic cylinder 4 to perform reverse operation, and the push plate 5 moves in the opposite direction and releases the drag on the filter plate 2. When the push plate 5 moves, it drives the triangular plate 10 to move, and the rack plate 11 moves accordingly and drives the spur gear 12 to rotate. When the spur gear 12 rotates, the first screw rod 7 rotates accordingly. At this time, the second screw rod 8 rotates simultaneously with the first screw rod 7 under the cooperation of the belt and the first belt pulley 9. It should be noted that the rotation directions of the first screw rods 7 on both sides are opposite, and the lifting plate 131 descends with the rotation of the first screw rod 7 and the second screw rod 8. The rectangular frame 132 moves with the lifting plate 131 and drives the extrusion plate 133 The surface of the squeeze plate 133 contacts the surface of the extension plate 3, so the descent of the squeeze plate 133 will squeeze and push the extension plate 3. At this time, the effect of the squeeze plate 133 on the extension plate 3 is similar to the use of the wedge block in the prior art. When the squeeze plate 133 descends, the extension plate 3 in contact with the squeeze plate 133 is forced to move. Since the extension plate 3 is fixed to the surface of the filter plate 2, when the extension plate 3 moves, the filter plate 2 can move along with it. Since the position of the filter plate 2 on the side away from the hydraulic cylinder 4 is limited by the bracket 1, when the extension plate 3 on the surface of the side filter plate 2 is squeezed and pushed, the position of the side filter plate 2 is relatively fixed. Therefore, the filter plate 2 adjacent to the side filter plate 2 moves in the direction of the hydraulic cylinder 4. The movement here is achieved through the cooperation between the inclined surface of the squeeze plate 133 and the extension plate 3. At this time, the positional relationship between the rectangular frame 132, the squeeze plate 133, the extension plate 3 and the filter plate 2 is as shown in the figure. Fig.11 As shown, Fig.11The positional relationship shown in the figure is as follows: the leftmost filter plate 2 is the filter plate 2 limited by the bracket 1. When the rectangular frame 132 descends, the squeezing plate 133 descends accordingly and squeezes the extension plate 3. The corresponding extension plate 3 drives the corresponding filter plate 2 to move, and in this process, the movement of the extension plate 3 can assist in driving the squeezing plate 133 to move horizontally, and the distance between two adjacent squeezing plates 133 increases. Thereafter, the extension plate 3, the filter plate 2 and the squeezing plate 133 can be horizontally reset by the cooperation of the hydraulic cylinder 4 and the reset mechanism 15. At the same time, under the cooperation of the second belt pulley 2622 and the belt, the adjusting rod 2621 drives the bevel gear plate 2623 to rotate, and the bevel gear 26 13 then drives the long rod 2611 to rotate, and the cam 2612 reciprocally presses the force-bearing plate 29 as the long rod 2611 rotates, and the thick plate 281 drives the knocking plate 282 to descend, and the knocking plate 282 repeatedly contacts the top of the filter plate 2 to knock the filter plate 2, so as to assist the discharge of the filter cake on the surface of the filter plate 2 by vibration. When the lifting plate 131 descends, the pull rope 21 is forced to pull the limit plate 193 to lift, and the support plate 192 then drives the connecting plate 191 to lift, and the elastic rope 22 can move along the surface of the filter plate 2 under the guidance of the auxiliary plate 233, so as to scrape the bottom of the filter cake on the surface of the filter plate 2, thereby assisting the discharge of the filter cake.
