Description

Technical Field

[0001] The present invention relates to the technical field of filter presses, and particularly to a filter press unit that facilitates discharging. Background Art

[0002] A filter press is a solid-liquid separation device. By applying pressure, the liquid passes through the filter medium while the solid particles are intercepted, thereby achieving solid-liquid separation. It is widely used in industries such as chemical engineering, pharmaceuticals, and metallurgy. The working principle of the filter press is based on surface filtration. During operation, the hydraulic cylinder presses all the filter plates tightly to form a sealed filter chamber. The slurry enters the filter plates through the feed holes of the filter plates under a certain pressure. The solid particles are intercepted by the filter plates to form filter cakes, and the liquid passes through the filter plates and is discharged.

[0003] Currently, when some filter presses are in use, the filter cakes are placed between two adjacent filter plates. Workers need to regularly use a plate puller to separate two adjacent filter plates in sequence and clean the filter cakes on the surfaces of the filter plates. During this process, workers need to use tools to scrape the filter cakes on the surfaces of each filter plate in sequence. This process is time-consuming and laborious. Moreover, when workers use tools to scrape and clean the filter cakes, the tools used by the workers are likely to collide with the surfaces of the filter plates and affect the filter cloth on the surfaces of the filter plates, thus affecting the normal progress of subsequent filter pressing operations. Summary of the Invention

[0004] The purpose of the present invention is to provide a filter press unit that facilitates discharging. When the push plate moves in the reverse direction, it can drive the lifting mechanism to descend. The extrusion plate can drive the filter plates to move by extruding the extension plate. The force application mechanism, the knocking mechanism, and the force receiving plate cooperate to repeatedly knock the top of the filter plates. The connection mechanism, the pulley, and the pull rope cooperate with the lifting mechanism to drive the elastic rope to lift, so as to scrape the lower part of the filter cake. This solves the problem that when some filter presses are in use, the method of workers using a plate puller and tools to discharge the filter cake is not only time-consuming and laborious, but also the tools are likely to collide with the filter plates and affect the normal progress of subsequent filter pressing operations.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 11, A filter press unit facilitating discharging, comprising a bracket 1, filter plates 2, extension plates 3 fixedly connected to the surfaces of the filter plates 2, hydraulic cylinders 4 installed on the surface of the bracket 1, and a push plate 5 fixedly connected to the piston rod of the hydraulic cylinder 4. The filter plates 2 are arranged inside the bracket 1, and the surfaces of the extension plates 3 are in contact with the surface of the bracket 1. The use of the hydraulic cylinders 4, the push plate 5, and the filter plates 2 are all existing mature technologies and are well-known to those skilled in the art, so no further elaboration will be made here. A fixed frame 6 is fixedly connected to the surface of the bracket 1. The number of the fixed frames 6 is four, and the four fixed frames 6 are arranged in pairs correspondingly. A first lead screw 7 is rotatably connected inside one side of the fixed frame 6, and a second lead screw 8 is rotatably connected inside the other side of the fixed frame 6. The number of both the first lead screw 7 and the second lead screw 8 is two. First pulley discs 9 are fixedly sleeved on the surfaces of one side of the first lead screw 7 and one side of the second lead screw 8 respectively, and the two first pulley discs 9 are connected by a belt in a transmission manner. Triangular plates 10 are fixedly connected to both sides of the top of the push plate 5. A rack plate 11 is fixedly connected to the surface of the triangular plate 10. A spur gear 12 is fixedly sleeved on the surface of the first lead screw 7. The rack plate 11 meshes with the spur gear 12. Since the relative positions of the two sides of the rack plate 11 and the two sides of the spur gear 12 are different, the thread directions of the two first lead screws 7 on both sides are opposite. A lifting mechanism 13 is arranged inside the fixed frame 6, and a reset mechanism 15 is installed on the surface of the fixed frame 6. A thin rod 16 is fixedly connected to the top of the filter plate 2, and a slider 18 is fixedly connected to the bottom of the thin rod 16. A clamping plate 17 is fixedly connected to the surface of the fixed frame 6. The surfaces of the thin rod 16 and the slider 18 are both in contact with the inner wall of the clamping plate 17. The cooperation use of the clamping plate 17, the slider 18, and the thin rod 16 can increase the stability of the thin rod 16 during movement. A connecting mechanism 19 is arranged on the surface of the thin rod 16. A pulley 20 is installed on the top of the fixed frame 6. A pulling rope 21 is arranged on the surface of the pulley 20. The two ends of the pulling rope 21 are respectively connected to the lifting mechanism 13 and the connecting mechanism 19. An elastic rope 22 is arranged on the surface of the connecting mechanism 19. The elastic rope 22 can scrape under the filter cake on the surface of the filter plate 2 so that the filter cake can be discharged quickly. An auxiliary mechanism 23 is installed at the bottom of the filter plate 2. The setting of the auxiliary mechanism 23 can not only assist the movement of the elastic rope 22 but also facilitate the storage of the elastic rope 22 in the idle state. A cross plate 24 is fixedly connected to the surface of the fixed frame 6, and a side plate 25 is fixedly connected to the top of the cross plate 24. A force-applying mechanism 26 is arranged on the surfaces of the cross plate 24 and the side plate 25. The force-applying mechanism 26 includes a force-applying component 261 arranged on the surface of the cross plate 24 and an adjusting component 262 arranged on the surface of the side plate 25. A cover plate 27 is fixedly connected to the surface of the cross plate 24, and a protective cover 30 is fixedly connected to the surface of the side plate 25. The bottom of the protective cover 30 is fixedly connected to the top of the cover plate 27. A knocking mechanism 28 is arranged on the top of the cover plate 27, and a force-receiving plate 29 is fixedly connected to the top of the knocking mechanism 28. The force-receiving plate 29 can cooperate with the force-applying component 261 for use.

[0034] The lifting mechanism 13 includes a lifting plate 131, a rectangular frame 132, and a pressing plate 133. There are four lifting plates 131, and the four lifting plates 131 are respectively threadedly sleeved on the surfaces of two first lead screws 7 and two second lead screws 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 fixed frame 6. The pressing plate 133 is slidably connected to the bottom of the rectangular frame 132. A T-shaped plate 14 is fixedly connected to the top of the pressing plate 133, and the surface of the T-shaped plate 14 is slidably connected to the inner wall of the rectangular frame 132. When the second lead screw 8 and the first lead screw 7 rotate, the four lifting plates 131 can rotate simultaneously, and the lifting plate 131 can drive the rectangular frame 132 to descend. The pressing plate 133 will descend accordingly and press the extension plate 3, so that the filter plate 2 can move, facilitating the discharge of the filter cake. During this process, the T-shaped plate 14 can increase the stability of the pressing plate 133 during movement;

[0035] The lifting plate 131 drives the rectangular frame 132 to descend, and the pressing plate 133 descends accordingly. When the pressing plate 133 in contact with the extension plate 3 descends, the inclined surface of the pressing plate 133 can push the extension plate 3, and the extension plate 3 can drive the filter plate 2 to move. During this process, when the extension plate 3 moves, the pressing plate 133 can move horizontally under the influence of the movement of the extension plate 3. At this time, the T-shaped plate 14 can guide the movement of the pressing plate 133. A schematic diagram of the lifting mechanism 13 adjusting the positions of the extension plate 3 and the filter plate 2 is as Figure 11 shown.

[0036] The reset mechanism 15 includes a thin plate 151, a smooth rod 152, a reset plate 153, and a first tension spring 154. The thin plate 151 is fixedly connected to the surface of the fixed frame 6. The smooth 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 smooth 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 is several. The two ends of the first tension spring 154 are respectively fixedly connected to the surfaces of two adjacent reset plates 153. When the pressing plate 133 descends, it presses the extension plate 3 to increase the distance between two adjacent extension plates 3. At this time, the distance between two adjacent filter plates 2 increases, facilitating the smooth falling of the filter cake. Thereafter, under the action of the elastic force of the first tension spring 154, two adjacent reset plates 153 move towards the opposite sides, and the extension plate 3 can drive the filter plate 2 to move back to its original position for subsequent use.

[0037] The connecting mechanism 19 includes a connecting plate 191, a support plate 192 and a limiting plate 193. The connecting plate 191 is slidably sleeved on the surface of the thin rod 16. The elastic cord 22 is fixedly connected to the surface of the connecting plate 191. A limiting groove is formed on the surface of the fixing frame 6. The surface of the limiting plate 193 is slidably connected to the inner wall of the limiting groove by a sliding rod. The support plate 192 is fixedly connected to the surface of the limiting plate 193. The surface of the support 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 support plate 192. When the lifting plate 131 descends, the pulling rope 21 pulls the limiting plate 193 accordingly. The support plate 192 drives the connecting plate 191 to lift accordingly. At this time, the elastic cord 22 rises accordingly to scrape the filter cake on the surface of the filter plate 2, so as to assist in discharging the filter cake.

[0038] The surface of the pulling rope 21 is in contact with the surface of the pulley 20. When the lifting mechanism 13 moves, the pulling rope 21 can move accordingly. At this time, the pulley 20 can guide the pulling rope 21. The pulley 20 assisting the movement of the pulling rope 21 can increase the smoothness of the pulling rope 21 during movement, so that the pulling rope 21 can drive the connecting mechanism 19 to move up and down with the movement of the lifting mechanism 13.

[0039] 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. The auxiliary plate 233 is fixedly connected to the top of the bottom plate 232. The auxiliary plate 233 is inclined. The surface of the elastic cord 22 is in contact with the surfaces of both the bottom plate 232 and the auxiliary plate 233. When the elastic cord 22 is idle, the bottom plate 232 can limit the position of the elastic cord 22. When the elastic cord 22 moves, the auxiliary plate 233 can assist in guiding the elastic cord 22. The elastic cord 22 is attached to the surface of the filter plate 2 during movement, so as to scrape the lower part of the filter cake on the surface of the filter plate 2 through the elastic cord 22, thereby assisting in discharging the filter cake.

[0040] The force - applying component 261 includes a long rod 2611, a cam 2612, and a bevel gear 2613. The long rod 2611 rotates through 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 is in contact with the top of the force - receiving plate 29. When the long rod 2611 rotates, the cam 2612 rotates accordingly and can reciprocally press the force - receiving plate 29, so that the knocking mechanism 28 can reciprocally lift and move to knock the bottom of the filter plate 2, thereby driving the filter cake to fall by vibration. The adjusting component 262 includes an adjusting rod 2621, two second belt pulleys 2622, and a bevel - gear disk 2623. The adjusting rod 2621 rotates through the top of the cross - plate 24. The number of the second belt pulleys 2622 is two. The two second belt pulleys 2622 are respectively fixedly sleeved on the surface of the adjusting rod 2621 and the surface of the second lead screw 8 on one side. The two second belt pulleys 2622 are connected by belt drive. The bevel - gear disk 2623 is fixedly connected to the top of the adjusting rod 2621. The bevel - gear disk 2623 meshes with the bevel gear 2613. When the second lead screw 8 rotates, it can drive the second belt pulley 2622 to rotate. At this time, when the adjusting rod 2621 rotates accordingly, it can drive the bevel - gear disk 2623 to rotate. When the bevel - gear disk 2623 rotates, it can drive the bevel gear 2613 to rotate, thereby driving the long rod 2611 to rotate.

[0041] The knocking mechanism 28 includes a thick plate 281, a knocking plate 282, an anti - detachment 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 - detachment 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 - detachment rod 283. The force - receiving plate 29 is fixedly connected to the top of the thick plate 281. When the cam 2612 rotates and presses the force - receiving plate 29, the force - receiving plate 29 can drive the thick plate 281 to descend. At this time, the knocking plate 282 descends accordingly and can knock 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 lift and reset.

[0042] Working principle: When the hydraulic cylinder 4 starts and drives the push plate 5 to move, the push plate 5 pushes the filter plates 2 so that several filter plates 2 can be fitted together. When the pulp passes through the filter plates 2, filtration can be carried out. The solid particles generated during the filtration process accumulate on the surface of the filter plates 2 and form filter cakes. After the pressure filtration operation is completed, the staff starts the hydraulic cylinder 4 for reverse operation. The push plate 5 moves in the reverse direction and releases the dragging of the filter plates 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 lead screw 7 rotates accordingly. At this time, the second lead screw 8 rotates simultaneously with the first lead screw 7 under the cooperation of the belt and the first pulley 9. It should be noted that the rotation directions of the first lead screws 7 on both sides are opposite. The lifting plate 131 descends with the rotation of the first lead screw 7 and the second lead screw 8. The rectangular frame 132 moves with the lifting plate 131 and drives the extrusion plate 133 to descend. Since the surface of the extrusion plate 133 contacts the surface of the extension plate 3, the descent of the extrusion plate 133 will extrude and push the extension plate 3. At this time, the effect of the extrusion plate 133 on the extension plate 3 is similar to the use of a wedge block in the prior art. When the extrusion plate 133 descends, the extension plate 3 in contact with the extrusion plate 133 moves under force. Since the extension plate 3 is fixed on the surface of the filter plate 2, when the extension plate 3 moves, the filter plate 2 can move accordingly. Also, since the position of the filter plate 2 on the side away from the hydraulic cylinder 4 is restricted by the bracket 1, when the extension plate 3 on the surface of this side of the filter plate 2 is extruded and pushed, the position of this side of the filter plate 2 is relatively fixed. Therefore, the filter plate 2 adjacent to this side of the filter plate 2 moves towards the direction where the hydraulic cylinder 4 is located. This movement is achieved through the cooperation of the inclined surface of the extrusion plate 133 and the extension plate 3. At this time, the positional relationship among the rectangular frame 132, the extrusion plate 133, the extension plate 3, and the filter plate 2 is as Figure 11 shown, Figure 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 extrusion plate 133 descends accordingly and extrudes the extension plate 3. Correspondingly, the extension plate 3 drives the corresponding filter plate 2 to move. And during this process, the movement of the extension plate 3 can assist in driving the extrusion plate 133 to move horizontally, and the distance between two adjacent extrusion plates 133 increases. Thereafter, the horizontal reset of the extension plate 3, the filter plate 2, and the extrusion plate 133 can be achieved through the cooperation of the hydraulic cylinder 4 and the reset mechanism 15. Meanwhile, under the cooperation of the second pulley 2622 and the belt, the adjusting rod 2621 drives the bevel gear disk 2623 to rotate, and the bevel gear 2613 drives the long rod 2611 to rotate accordingly. When the cam 2612 rotates with the long rod 2611, it repeatedly presses the force-bearing plate 29. 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 in discharging the filter cake on the surface of the filter plate 2 by vibration. When the lifting plate 131 descends, the pull rope 21 is stressed to pull the limiting plate 193 to lift, and the support plate 192 drives the connecting plate 191 to lift accordingly. 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 in discharging the filter cake.
