Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery recycling technology, and in particular to a lead-acid battery casing perforation device. Background Technology

[0002] The recycling of used lead-acid batteries has multiple benefits, including reducing environmental pollution, achieving resource recycling, and lowering production costs. During the recycling process, because used lead-acid batteries contain sulfuric acid electrolyte, perforation is necessary before recycling to collect and discharge the electrolyte. This facilitates subsequent crushing and sorting operations, improving recycling efficiency. Furthermore, perforation can release any residual gases before the batteries are crushed, reducing safety risks during processing. However, existing perforation devices suffer from low perforation efficiency and are impact-type perforations lacking limiting mechanisms, posing certain safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a perforation device for lead-acid battery casings, which can quickly achieve perforation of lead-acid battery casings.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A perforation device for a lead-acid battery casing includes a perforation bracket, with a first conveyor roller and a second transmission roller rotatably mounted at both ends of the perforation bracket, and a first conveyor belt and a second conveyor belt rotatably mounted on the first conveyor roller and the second conveyor roller, with the first conveyor belt and the second conveyor belt being spaced apart.

[0006] A perforation module is provided on the perforation bracket. The perforation module includes a portal support frame. A telescopic cylinder is vertically downwardly provided on the portal support frame. A perforation frame is fixed on the piston rod of the telescopic cylinder. A perforation motor is vertically downwardly provided inside the perforation frame. A perforation drill bit is fixed on the rotor of the perforation motor.

[0007] The perforated frame is slidably engaged inside the portal frame.

[0008] As an improvement: a first conveyor baffle is provided on the first conveyor belt, and a second conveyor baffle is provided on the second conveyor belt, with the first conveyor baffle and the second conveyor baffle arranged symmetrically.

[0009] As an improvement, a pressure sensor is provided at the joint between the piston rod of the telescopic cylinder and the perforated frame.

[0010] As an improvement: a receiving groove is provided below the first conveyor belt body, the receiving groove is fixed on the perforated bracket, a filter screen is provided inside the receiving groove, and several drain pipes are provided below the receiving groove.

[0011] As an improvement, several limiting modules are provided at the bottom of the portal support frame. Each limiting module includes an elastic telescopic limiting rod, which is fixed vertically downward inside the portal support frame. A limiting plate is fixed at the bottom end of the elastic telescopic limiting rod.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. When the lead-acid battery moves to the bottom of the drilling bit, the telescopic cylinder is activated to move downwards, and the drilling motor drives the drilling bit to rotate, penetrating the lead-acid battery. The above operation can quickly achieve the drilling operation of the lead-acid battery.

[0014] 2. After being perforated, the lead-acid battery continues to move to the right under the action of the conveyor belt. During the movement, the sulfuric acid liquid inside flows into the receiving tank through the perforation, which does not affect the next perforation operation and improves the perforation efficiency.

[0015] 3. During perforation, the limiting plate on the elastic telescopic limiting rod will abut against the surface of the lead-acid battery to achieve the limiting operation. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Please refer to Figures 1-2 A perforation device for a lead-acid battery casing includes a perforation bracket 1, a first conveyor roller 2 and a second transmission roller 3 rotatably mounted at both ends of the perforation bracket 1, and a first conveyor belt body 4 and a second conveyor belt body 5 rotatably mounted on the first conveyor roller 2 and the second conveyor roller 3, with the first conveyor belt body 4 and the second conveyor belt body 5 spaced apart.

[0022] A perforation module is provided on the perforation bracket 1. The perforation module includes a portal support frame 6. A telescopic cylinder 7 is provided vertically downward on the portal support frame 6. A perforation frame 8 is fixed on the piston rod of the telescopic cylinder 7. A perforation motor 9 is provided vertically downward inside the perforation frame 8. A perforation drill bit 10 is fixed on the rotor of the perforation motor 9.

[0023] The perforated frame 8 is slidably locked inside the portal support frame 6.

[0024] In this embodiment, when the lead-acid battery moves to below the drilling bit 10, the telescopic cylinder 7 is activated to move downward, and the drilling motor 9 drives the drilling bit 10 to rotate, penetrating the lead-acid battery. Through the above operation, the drilling operation of the lead-acid battery can be quickly achieved.

[0025] A drilling support plate 11 is provided below the first conveyor belt body 4 and the second conveyor belt body 5, opposite to the drilling bit 10, which is used to bear the downward pressure during drilling.

[0026] After being perforated, the lead-acid battery continues to move to the right under the action of the conveyor belt. During the movement, the sulfuric acid liquid inside flows into the receiving tank 15 through the perforation, without affecting the next perforation operation, thus improving the perforation efficiency.

[0027] A first conveyor baffle 12 is provided on the first conveyor belt 4, and a second conveyor baffle 13 is provided on the second conveyor belt 5, with the first conveyor baffle 12 and the second conveyor baffle 13 arranged symmetrically. In this embodiment, the conveying speeds of the first conveyor belt 4 and the second conveyor belt 5 are the same, and the first conveyor baffle 12 and the second conveyor baffle 13 can limit the lead-acid battery between them.

[0028] A pressure sensor 14 is provided at the joint between the piston rod of the telescopic cylinder 7 and the perforation frame 8. In this embodiment, the pressure sensor 14 can sense whether the perforation drill bit 10 is acting on the lead-acid battery, and the pressure on the perforation drill bit 10 during perforation, to prevent excessive pressure from damaging the drill bit.

[0029] A receiving trough 15 is provided below the first conveyor belt body 4. The receiving trough 15 is fixed on the perforated bracket 1. A filter screen plate 16 is provided inside the receiving trough 15. Several drain pipes 17 are provided below the receiving trough 15. In this embodiment, the receiving trough can be used to receive sulfuric acid liquid and filter it at the same time.

[0030] Several limiting modules are provided at the bottom of the portal frame 6. Each limiting module includes an elastic telescopic limiting rod 18, which is fixed vertically downward inside the portal frame 6. A limiting plate 19 is fixed at the bottom end of the elastic telescopic limiting rod 18. During perforation, the limiting plate 19 on the elastic telescopic limiting rod 18 will abut against the surface of the lead-acid battery, thereby limiting its movement.

[0031] Working principle: The lead-acid battery to be pierced is placed on the first conveyor belt 4 and the second conveyor belt 5 in sequence. When it moves to the bottom of the piercing drill bit 10, the telescopic cylinder 7 is activated to move downward. The limiting plate 19 abuts against the lead-acid battery to be pierced and squeezes and limits it. Then the piercing motor 9 drives the piercing drill bit 10 to rotate and penetrate the lead-acid battery.

[0032] After being perforated, the lead-acid battery continues to move to the right. During this movement, the sulfuric acid inside the battery flows into the receiving tank and is filtered by the filter screen 16 in the receiving tank.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
