Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery treatment facilities, and in particular relates to a zero-leakage lead-acid battery storage bin. Background Art

[0002] In recent years, recycling companies have successively established a number of lead-acid battery production, recycling and comprehensive utilization bases, but the storage of waste batteries is not standardized or scientific, which has caused prominent environmental pollution problems, especially soil pollution. Lead-acid batteries include car batteries, electric vehicle batteries, UPS batteries, forklift tricycle batteries, communication base station batteries, motorcycle batteries, ordinary emergency batteries, etc. Among these categories, car batteries and forklift tricycle batteries usually contain about 15%-30% acid. During the collection and storage process, due to the stacking in any direction, the sulfuric acid in the battery contacts the bottom of the storage for a long time. Although the storage has a special acid-proof and anti-corrosion floor, after long-term immersion, the acid and the acid containing about 4%-5% lead will penetrate into the soil under the anti-corrosion layer, causing soil acidification and heavy gold. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a zero-leakage lead-acid battery storage bin, which can serve as an intermediate bin for transporting batteries for safe storage, effectively preventing acid from leaking into the surface layer, achieving zero acid leakage and having no impact on the surrounding environment.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A zero-leakage lead-acid battery storage bin comprises upper and lower corresponding battery storage bins and an emergency plan pool, wherein the floor of the battery storage bin is made of a reinforced concrete layer, the upper part of the reinforced concrete layer is covered with granite slabs, and acid-proof resin is coated in the gaps of the granite slabs, the battery storage bin is provided with open channels on at least two sides, a waste liquid tank is arranged outside the battery storage bin, and the open channel is connected to the waste liquid tank; the bottom of the emergency plan pool is a clay layer, and a cement concrete layer is covered on the clay layer.

[0006] The front part of the battery storage bin of the present invention is provided with a transport vehicle entrance and a ramp.

[0007] A flushing area is arranged on one side of the battery storage bin of the present invention. The flushing area has a water tank connected to a sedimentation tank. An overflow port is arranged above the sedimentation tank and connected to a circulation tank. The circulation tank supplies water to the flushing area through a pumping device.

[0008] The thickness of the reinforced concrete layer of the present invention is 20 cm, and the thickness of the granite slab is 5 cm.

[0009] The thickness of the clay layer of the present invention is 100 cm, and the thickness of the cement concrete layer is 15 cm.

[0010] An observation window is provided on the side of the emergency plan pool of the present invention.

[0011] The intended effect of the present invention is that it allows transport vehicles to enter and gradually unload goods. Combined with the flushing area of ​​the transport vehicles, the transport vehicles can enter the flushing area for flushing after unloading, ensuring that the acid flowing out of the waste batteries does not flow out, leak, or contact the ground. An emergency plan pool is configured to carry out daily inspections, which can achieve zero leakage of acid and protect the surface soil from pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Reference Figures 1 to 3 As shown, a zero-leakage lead-acid battery storage bin has a battery storage bin 1 and an emergency plan pool 2 corresponding to the upper and lower parts. The battery storage bin 1 can use stainless steel as a frame, and the inner surface of the battery storage bin 1 can be built with plates or concrete to form a space body similar to a garage. The ground of the battery storage bin 1 uses a reinforced concrete layer 11, and the reinforced concrete layer 11 is covered with a granite slab 12. The thickness of the reinforced concrete layer 11 is 20 cm, and the thickness of the granite slab 12 is 5 cm. Acid-proof resin is coated in the gap of the granite slab 12 so that the granite slab 12 completely covers the reinforced concrete layer 11. The upper battery storage bin 1 has a two-layer leak-proof structure. The granite slab 12 can effectively prevent acid and alkali corrosion, and the reinforced concrete layer 11 can make the battery storage bin 1 rigid.

[0017] The front of the battery storage bin 1 is provided with a transport vehicle entrance 5 and a ramp 51 , and the transport vehicle can enter the battery storage bin 1 from the ramp 51 , and gradually unload the goods from the inside to the outside, and stack the waste lead-acid batteries in the battery storage bin 1 .

[0018] Since the battery storage bin 1 has an open transport vehicle entrance 5, the battery storage bin 1 is provided with open channels 3 on at least two sides, and an open channel 3 can also be added at the rear end of the battery storage bin 1. The open channel 3 can also be formed by a reinforced concrete layer 11 and a granite slab 12, or the open channel 3 can be configured with a PVC chemical pipeline alone. During the stacking of waste lead-acid batteries, the acid will flow into the open channel 3, and a waste liquid tank 4 is configured outside the battery storage bin 1. There can be multiple waste liquid tanks 4. The open channel 3 is connected to the waste liquid tank 4 through a conduit, so that the acid entering the open channel 3 can be collected in the waste liquid tank 4 located outside the battery storage bin 1 through a guide roller, and then sent to a sewage treatment station for treatment.

[0019] The conduit connecting the open channel 3 and the waste liquid tank 4 can be a dedicated PVC chemical pipeline, which has strong acid and alkali resistance.

[0020] Below the battery storage bin 1 is the emergency plan pool 2, the bottom of the emergency plan pool 2 is a clay layer 21, and the clay layer 21 is covered with a cement concrete layer 22, wherein the clay layer 21 is 100 cm thick, and its leakage coefficient is less than 10-7 cm / s, while the cement concrete layer 22 is 15 cm thick, and the cement concrete layer 22 is surrounded by concrete or steel structures as columns, so that there is an effective reserved space of a certain depth in the emergency plan pool 2, and the effective volume of the reserved space can be more than 2000 cubic meters, as long as there is acid dripping on the cement concrete layer 22, the traces of the acid are clearly visible. For the convenience of observation, an observation window 20 is provided on the side of the emergency plan pool 2, and only a dedicated person is responsible for daily inspection with a lighting lamp to observe whether there are traces of liquid in the emergency plan pool 2, and it can be known whether the upper battery storage bin 1 is damaged, so that emergency disposal can be carried out in the first time when leakage occurs.

[0021] The position of the observation window 20 is set according to the depth of the emergency plan pool 2. If the internal depth of the emergency plan pool 2 is less than 50 cm, a clay layer 21 and a cement concrete layer 22 can be directly constructed on the surface, that is, the emergency plan pool 2 is entirely located above the surface, and multiple observation windows 20 can be set on both sides of the emergency plan pool 2. The observation windows 20 can be covered with glass, and the height of the observation window 20 is not more than 170 cm. The inspection personnel can stand normally and observe the internal situation of the emergency plan pool 2 through the observation window 20; if the internal depth of the emergency plan pool 2 is greater than 1 meter, a pit of more than 1 meter can be dug on the surface, the emergency plan pool 2 is built in the pit, and the observation window 20 can be set to be open in the same direction as the transport vehicle entrance 5, and the inspection and maintenance personnel can directly bend down and enter the emergency plan pool 2 through the observation window 20 for inspection.

[0022] A washing area 6 is provided on one side of the battery storage bin 1 for washing the transport vehicles after unloading. The washing area 6 can also be located above the emergency plan pool 2, or can be directly built on the ground surface, so that the battery storage bin 1 and the washing area 6 are separated only by a partition or a partition wall, and the partition or the partition wall can have a transport vehicle flow port, so that the transport vehicles that have unloaded the goods in the battery storage bin 1 can directly enter the washing area through the transport vehicle flow port without leaving the battery storage bin 1 and then entering the washing area 6.

[0023] Specifically, the flushing area 6 has a water trough 61 connected to the sedimentation tank 7, and an overflow port 71 is provided above the sedimentation tank 7 to connect to the circulation tank 72. The circulation tank 72 supplies water to the flushing area 6 through a pumping device. After unloading, the transport vehicle enters the flushing area 6. The water for washing comes from the circulation tank 72, and the waste water after washing enters the sedimentation tank 7 through the water trough 61 for precipitation, so that the dirt and impurities in the waste water enter the sedimentation tank 7, and the upper liquid overflows into the circulation tank 72. Since the acid on the transport vehicle will be taken away during the flushing process and eventually enter the circulation tank 72, it is necessary to test the pH value of the liquid in the circulation tank 7 every day. If the acid is relatively high, caustic soda should be added for neutralization. The flushing area 6 can ensure that the flushing sewage does not flow out and prevent lead-containing and acid-containing waste from leaking out.

[0024] It should be understood that the technical scope of the present invention is not limited to the contents of the specification. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
