Description

Technical Field

[0001] The invention relates to the technical field of waste battery recycling, and in particular to a lead paste filter pressing and recycling device for lead-acid battery recycling. Background Art

[0002] Acid batteries are still an indispensable power source for motor vehicles and ships. Due to corrosion, passivation and other reasons, lead-acid batteries cannot be used after 2-4 years of use. How to better recycle the useful substances in waste lead-acid batteries is not only related to the protection of national heavy metal resources, but also in line with the national sustainable development strategy of protecting the environment and developing a circular economy. The basic raw materials for manufacturing lead-acid batteries are metallic lead and sulfuric acid. In the process of producing and using lead-acid batteries, lead compounds are formed on the battery plates through a series of chemical reactions, mainly oxides such as lead oxide, lead dioxide and lead salts such as lead sulfate. The purpose of recycling is to use these metals and metal compounds as lead products after proper treatment. The cost of recycled lead is only equivalent to 1 / 3 of the cost of mining and smelting from primary ore, so it is of great significance.

[0003] After being crushed, used lead-acid batteries are sent to a hydraulic classification box for classification. The light part with low density flows to a horizontal screen. The lead paste under the screen is discharged by a de-paste machine and needs to be sent to a filter press for filtration after being slurried in a slurry tank. Although the existing filter press can filter the lead paste, its production efficiency is low and the cost is high, which cannot meet the needs of mass production.

[0004] The patent with patent announcement number CN210356170U discloses a filter press for lead paste recovery, including a support and a beam guide fixedly arranged on the support along the left and right directions, a thrust plate and a clamping plate are arranged between the two beam guides, a hydraulic telescopic cylinder is arranged on the right side of the clamping plate, and multiple filter press plates are arranged in parallel with each other at intervals between the thrust plate and the clamping plate, and support rods are fixedly arranged at the front and rear ends of the filter press plate. The filter press plate includes a plate frame, a center plate and a filter cloth, and the upper and lower parts of the plate frame are provided with water outlet holes along the left and right directions, the filter cloth passes through the material hole and the edge of the filter cloth is fixedly arranged on the frame of the plate frame, and multiple circular protrusions are fixedly arranged on the left and right side surfaces of the center plate, and sliding tracks are fixedly arranged on the outer sides of the front and rear beam guides, and an electric walking trolley is installed on the sliding track, and a lever is vertically fixed on the electric walking trolley. Although this device improves the filter pressing efficiency of the lead paste, reduces the production cost, and meets the needs of mass production, it is inconvenient to remove the lead paste remaining on the filter plate after the filter pressing of the lead paste.

[0047] After the filtration is completed, the cylinder 10 is retracted, and then the first motor 4 is used to drive the lead screw 15 to rotate. When the slide plate 14 moves to the left side of the slider 13 below the extrusion plate 7, the telescopic rod 17 is started to move upward, and then the slide plate 14 drives the telescopic rod 17 to move to the right, and the extrusion plate 7 and the slider 13 below it can move to the right under the blocking effect of the telescopic rod 17. The distance that the slide plate 14 and the extrusion plate 7 move to the right is controlled so that the extrusion plate 7 is located in the rightmost fixing frame 5.

[0048] The slide plate 14 is made to reciprocate in the left and right directions and cooperates with the telescopic movement of the telescopic rod 17, so that the slide plate 14 can drive the filter plate 19 and the thrust plate 20 to move to the right direction and separate the filter plates 19 from each other during the movement of the slide plate 14 to the right direction. The distance that the slide plate 14 moves to the right direction is controlled, and the filter plates 19 are all located in one fixing frame 5, and the thrust plate 20 is located in the fixing frame 5 on the far left.

The driving unit includes a second motor 9 located in the flushing chamber, the axial direction of the second motor 9 is parallel to the left and right directions of the housing 1, the second motor 9 is fixed to the fixing frame 5 on the left side thereof, and a gear 28 is fixed to the output shaft of the second motor 9, the gear 28 can mesh with the rack 27 and drive the flushing assembly to move along the second slide 22. The second motors 9 of two adjacent driving assemblies rotate in opposite directions.

[0052] The first flushing block 23, the second flushing block 24 and the third flushing block 8 are all hollow structures. A plurality of spray holes are provided on one side of the first flushing block 23, the second flushing block 24 and the third flushing block 8 toward the center direction of the fixing frame 5. The first flushing block 23, the second flushing block 24 and the third flushing block 8 are connected by a hose, and the water pump is connected to the first flushing block 23 by a soft water inlet pipe.

[0053] A vertical third slide groove 29 is provided on the vertical portion of the fixed frame 5 on the left and right sides of the flushing chamber, and a rope collecting box 32 is slidably arranged in the third slide groove 29, a connecting rod 31 is fixed on the rope collecting box 32, and a wedge block 21 is fixed on the connecting rod 31, and the inclined surfaces of the left and right wedge blocks 21 in the flushing chamber are inclined downward at the relative ends, the first connecting column 25 on the third flushing block 8 is fixedly connected to the pull rope 30 of the rope collecting box 32 on one side thereof, and the first connecting column 25 on the second flushing block 24 is fixedly connected to the pull rope 30 of the rope collecting box 32 on one side thereof.

[0054] Two left-right symmetrical third connecting columns 33 are fixed to the front and rear sides of the upper ends of the thrust plate 20 , the filter plate 19 and the extrusion plate 7 , and the axial direction of the third connecting column 33 is perpendicular to the left-right direction of the housing 1 .

[0055] A rope collecting wheel is rotatably connected to the rope collecting box 32, and the rope collecting wheel and the rope collecting box 32 are connected by a coil spring. One end of the pull rope 30 is fixed to the rope collecting wheel, and part of the pull rope 30 is wound around the rope collecting wheel. The other end of the pull rope 30 passes through the opening of the rope collecting box 32 and extends to the outside of the rope collecting box 32.

[0056] When it is necessary to flush the filter plate 19, the thrust plate 20 and the extrusion plate 7, in the initial state, the first flushing block 23, the second flushing block 24 and the third flushing block 8 are located on the upper side of the flushing chamber, and the water pump is started. The water pump allows the cleaning liquid to be sprayed out through the spray holes of the first flushing block 23, the second flushing block 24 and the third flushing block 8 to flush the filter plate 19, the thrust plate 20 and the extrusion plate 7 in the vertical direction.

[0057] When it is necessary to flush the filter plate 19, the thrust plate 20 and the squeeze plate 7 in the longitudinal direction, as shown in FIG. Fig.12 As shown, the four second motors 9 on the fixed frame 5 are started, and under the cooperation of the gear 28 and the rack 27, and the guiding effect of the second slide groove 22 on the first connecting column 25 and the second connecting column 26, the first flushing block 23, the second flushing block 24 and the third flushing block 8 will move along the second slide groove 22.

[0058] Since the second motors 9 of the two adjacent driving assemblies rotate in opposite directions, the movement directions of the two adjacent flushing assemblies are opposite after the second motor 9 is started.

[0059] like Fig.14 As shown, in this embodiment, the first flushing assembly from left to right moves toward the rear side, and the second flushing assembly from left to right moves toward the front side, and the two adjacent flushing assemblies are staggered front and back in the left-right direction.

[0060] In this embodiment, for the convenience of description, the first flushing assembly from left to right is the first flushing assembly, and the first flushing chamber from left to right is the first flushing chamber. During the movement of the first flushing assembly toward the rear side, when the rack 27 on the third flushing block 8 that moves to the rear side of the first flushing chamber is meshed with the gear 28 at the rear side of the first flushing chamber, the gear 28 that rotates at the rear side of the first flushing chamber can drive the first flushing assembly to continue to move downward. At the same time, the pull rope 30 at the rear side of the first flushing chamber is rolled up in the rope collection box 32 at the rear side, and the pull rope 30 at the front side of the first flushing chamber drives the rope collection box 32 at the front side of the first flushing chamber to move upward, and when the rope collection box 32 at the front side of the first flushing chamber moves upward, it drives the two connecting rods 31 and two wedge blocks 21 at the front side of the first flushing chamber to move upward.

[0061] When the inclined surfaces of the two wedges 21 at the front side of the first flushing chamber contact the two adjacent third connecting columns 33 on the thrust plate 20 and the filter plate 19 on one side thereof, the thrust plate 20 and the adjacent filter plate 19 rotate around the fourth connecting column 34 below them respectively, and at the same time, the torsion spring accumulates force. The front end of the thrust plate 20 and the front end of the adjacent filter plate 19 are close to each other, that is, an inverted V-shaped groove is formed between the thrust plate 20 and the adjacent filter plate 19, and the flared end of the inverted V-shaped groove formed between the thrust plate 20 and the adjacent filter plate 19 faces the first flushing assembly.

[0062] Similarly, the expanded end of the inverted V-shaped groove formed between two adjacent filter plates 19 faces the flushing component in a vertical state on one side. The expanded end of the inverted V-shaped groove formed between the extrusion plate 7 and its adjacent filter plate 19 faces the flushing component in a vertical state on one side. At this time, the thrust plate 20, multiple filter plates 19 and the extrusion plate 7 are arranged in a zigzag shape.

[0063] Then, the water pump is started, and the cleaning liquid discharged from the flushing assembly can flush the opposite end surfaces of the extrusion plate 7, the filter plate 19 and the thrust plate 20 in the longitudinal direction.

[0064] The rotation direction of the second motor 9 can be changed, thereby changing the direction of the flared end of the inverted V-shaped groove formed between the thrust plate 20 and its adjacent filter plate 19, the direction of the flared end of the inverted V-shaped groove formed between two adjacent filter plates 19, and the direction of the flared end of the inverted V-shaped groove formed between the extrusion plate 7 and its adjacent filter plate 19, and the thrust plate 20, the extrusion plate 7 and the filter plate 19 are flushed by using a flushing component in which one side of the flared end of the inverted V-shaped groove is in a vertical state.

[0065] like Fig.14 As shown, in this embodiment, when the rotation direction of the second motor 9 is not changed, the flared end of the inverted V-shaped groove formed between the thrust plate 20 and the adjacent filter plate 19 faces the rear side.

[0066] When the rotation direction of the second motor 9 is changed, the expanded end of the inverted V-shaped groove formed between the thrust plate 20 and the adjacent filter plate 19 faces the front side.

[0067] By changing the rotation direction of the second motor 9 and starting the water pump, the flushing assembly can flush the thrust plate 20, the filter plate 19 and the extrusion plate 7 back and forth in the longitudinal direction, respectively, thereby improving the flushing effect.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
