Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery processing, and in particular to negative pressure acid adding equipment for lead-acid battery processing. Background Art

[0002] Lead-acid battery is a common rechargeable battery that uses lead and lead oxide as electrode materials and sulfuric acid as electrolyte. After the lead-acid battery is added with acid, the acid is absorbed by the electrode group slowly due to its tight internal structure. In order to speed up the absorption of the acid by the electrode group, it is often necessary to evacuate the interior of the lead-acid battery so that the acid rises and fully contacts the electrode group. Generally, 4-5 vacuum operations are required before the acid can be completely absorbed by the electrode group.

[0003] In the prior art, due to the large size of lead-acid batteries, when evacuating the interior of the lead-acid batteries, workers often use handheld vacuum pumping components to evacuate the lead-acid batteries one by one. During each operation, it is also necessary to ensure the sealing between the vacuum pumping component and the lead-acid battery to ensure that gas does not leak.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-4As shown, a negative pressure acid-adding device for processing lead-acid batteries includes a liquid storage tank 1, a liftable sealing cover 2 is arranged above the liquid storage tank 1, and the length and width of the sealing cover 2 are smaller than the liquid storage tank 1, an exhaust pipe 3 is arranged on the top of the sealing cover 2, and the exhaust pipe 3 is a right-angle pipe, and its output port is provided with a flange for fixing the pipeline, a plurality of groups of side reinforcing plates 4 are arranged at intervals on both sides of the inner wall of the sealing cover 2, a plurality of groups of end reinforcing plates 5 are arranged at intervals on the two end surfaces of the inner wall of the sealing cover 2, and the side reinforcing plates 4 and the end reinforcing plates 5 are horizontally and vertically distributed, support components are arranged at both ends of the liquid storage tank 1, and a bearing plate 7 for placing the lead-acid battery is arranged on the support component, and the bearing plate 7 is horizontally and laterally distributed, and a floating airbag is arranged at the bottom of the bearing plate 7 16, wherein, when the carrying plate 7 rises, its outer edge contacts with the side reinforcing plate 4 and the end reinforcing plate 5, and the three form a cross structure. The side reinforcing plate 4 and the end reinforcing plate 5 are both in the shape of a right triangle, and one side of the hypotenuse contacts with the outer edge of the carrying plate 7. The supporting assembly includes a guide rod 6 sleeved on the inner side of both ends of the carrying plate 7, and the carrying plate 7 can slide along the direction of the guide rod 6. A blocking block is provided at the top of the guide rod 6, and a support spring 17 is sleeved on the outer side of the guide rod 6, and the support spring 17 is located below the carrying plate 7. Auxiliary racks 18 are symmetrically provided at both ends of the carrying plate 7, and the auxiliary racks 18 are located on both sides of the guide rod 6, and one end is rotatably connected to the carrying plate 7. The bottom wall of the liquid storage tank 1 is symmetrically provided with the auxiliary racks 18. A matching buffer cover 19 is provided with a transverse spring 20 inside the buffer cover 19, a slide groove 21 is provided on the top of the buffer cover 19, and a hinge seat 22 connected to the transverse spring 20 is slidably provided inside the transverse spring 20, and the hinge seat 22 is rotatably connected to the other end of the auxiliary frame rod 18. When the lead-acid battery is placed on the load-bearing plate 7, the weight of the lead-acid battery will cause the load-bearing plate 7 to move downward to squeeze the support spring 17. At this time, the guide rod 6 limits the movement of the load-bearing plate 7 to ensure the stability of the load-bearing plate 7 during movement. At this time, the load-bearing plate 7 will squeeze the transverse spring 20 to both sides through the auxiliary frame rod 18, and the cooperation of the transverse spring 20 and the support spring 17 forms a good elastic support for the load-bearing plate 7, which will be used for subsequent lead-acid battery extraction. When the battery is empty, firstly, water is poured into the liquid reservoir 1 so that the liquid level is below the floating airbag 16, and then the sealing cover 2 is driven to descend so that the sealing cover 2 covers the bearing plate 7 and the lead-acid battery, and the bottom of the sealing cover 2 is immersed in the water in the liquid reservoir 1, and the bottom of the sealing cover 2 is sealed by the water, so that the interior of the sealing cover 2 is in a closed device, and the exhaust pipe 3 is externally connected to a vacuum pumping device, and the gas inside the sealing cover 2 and the lead-acid battery is discharged through the exhaust pipe 3. In the process of continuous vacuum pumping, the air pressure inside the sealing cover 2 gradually decreases. At this time, the water will flow into the sealing cover 2 under the action of atmospheric pressure, thereby submerging the floating airbag 16. At this time, the bearing plate 7 is supported by a larger buoyancy, and combined with the elastic force of the transverse spring 20 and the support spring 17,The supporting plate 7 can be loaded with lead-acid batteries and rise with the liquid level, thereby avoiding the water body submerging the lead-acid batteries during the vacuuming process. When the supporting plate 7 rises with the water body, the edge of the supporting plate 7 contacts the side reinforcing plate 4 and the end reinforcing plate 5. The three form a cross structure that can support the outer wall of the sealing cover 2, greatly reducing the risk of deformation caused by a large negative pressure inside the sealing cover 2.

[0027] In this embodiment, specifically, two groups of adjustment grooves 8 distributed laterally are provided on the top of the bearing plate 7, and a plurality of groups of moving seats 9 are slidably arranged inside the adjustment grooves 8.

Fixed plates 12 for supporting the bidirectional screw rod 11 are symmetrically arranged at both ends of the bottom of the bearing plate 7, and a toothed disc 13 is arranged on the outside of one end of the two groups of bidirectional screw rods 11, and the outer side of the toothed disc 13 is meshed with the outer side of the toothed disc 13. There is a transmission chain 14, and one end of a group of bidirectional screw rods 11 passes through one side of the fixed plate 12 and is provided with a hand wheel 15. When the lead-acid battery is placed on the load-bearing plate 7, the staff can drive a group of bidirectional screw rods 11 to rotate through the hand wheel 15. When a group of bidirectional screw rods 11 rotates, the transmission structure formed by the toothed plate 13 and the transmission chain 14 can synchronously drive another group of bidirectional screw rods 11 to rotate, so that the anti-floating splint 10 is adjusted from both ends, so that the anti-floating splint 10 can form a good clamping for lead-acid batteries of different specifications, avoiding the lead-acid battery from floating on the water and overturning and ingress of water, and forming a good protection for the lead-acid battery.

[0028] In the present embodiment, specifically, a drain pipe 23 for draining water is provided at one end of the liquid reservoir 1, a support frame 24 is provided at the top of the liquid reservoir 1, a driving wheel 25 is rotatably provided at the center of the top of the support frame 24, driven wheels 26 are rotatably provided on both sides of the top of the support frame 24, and the diameter of the driven wheel 26 is smaller than the driving wheel 25, and a belt 27 is provided on the outer side of the driving wheel 25 and the driven wheel 26, and a lifting screw 28 for driving the sealing cover 2 to rise and fall is rotatably provided at both ends of the bottom wall of the liquid reservoir 1, and the lifting screw 28 is located on the outer side of the guide rod 6, and the top of the lifting screw 28 is connected to the driven wheel 26, and the support A fixing frame 29 is provided on the top of the support frame 24, and a servo motor 30 for driving the driving wheel 25 to move is provided on the fixing frame 29. When the device is in use, the driving wheel 25 can be driven to rotate by the servo motor 30, and the driven wheel 26 is driven by the belt 27 to form a transmission, so that the driven wheel 26 can drive the lifting screw 28 to rotate synchronously. By controlling the rotation of the lifting screw 28 in different directions, the sealing cover 2 can be driven to rise and fall, thereby facilitating the loading and unloading of lead-acid batteries. The fixing frame 29 supports the servo motor 30, ensuring that the servo motor 30 has good stability when working.
