Problems solved by technology
In addition, the centrifugal lead pump always operates inside the high-temperature molten lead, which requires frequent repair and maintenance, cumbersome operation, and will increase the oxidation of lead
[0006] There are also some enterprises that use high-level lead supply to transport molten lead. This method can keep the surface of molten lead liquid in the melting pot still and reduce the oxidation of lead. There is no pressure to supply lead, and the speed is very slow, which will affect production efficiency and product quality, and has been gradually abandoned by the production plant
[0007] Currently, there is no better way to reduce lead losses during melting and pumping

Embodiment Construction
[0016] see figure 1 , The inside of lead-melting furnace 2 is provided with airtight feed bin 3, and this feed bin is a stainless steel drum, and its top has intake and exhaust pipe 5 with electromagnetic valve 6, and electromagnetic valve is controlled by time relay 7. There is a lead outlet 1 at the bottom of the silo, which communicates with the lead pipe 9, and the bottom side has a lead inlet 12, and a turn switch 13 is respectively adorned in the lead outlet 1 and the lead inlet 12. A floating stainless steel hollow ball 10 is arranged inside the feed bin. The feed bin is fixed on the support 4 that is connected with the furnace wall of the lead melting furnace. The steering switch is connected with the rotating shaft 8 to form a linkage structure. When one switch is turned on / off, the other switch is turned off / on, and the rotating shaft is supported on the support. The lead inlet and the lead outlet are located at the middle and lower parts of the molten lead liquid ...

Provided is a pneumatic lead pumping device for manufacturing lead-acid storage batteries. A sealed stock bin is arranged in a lead smelting furnace. An air inlet and exhaust pipe is arranged on the top of the stock bin. The bottom of the stock bin is provided with a lead inlet and a lead outlet which are each provided with a reversing switch. A hollow floating ball is arranged in the stock bin. When the pneumatic lead pumping device is used for pumping lead during manufacturing of the lead-acid storage batteries, the reversing switches rotate to act, the lead inlet is closed, the lead outlet is opened, air is rapidly fed into the stock bin through the air inlet and exhaust pipe, and molten lead is pushed to rapidly overflow from the lead outlet and conveyed to a lead usage position. Conversely, a lead feeding action of the stock bin is completed. The device is high in lead supply speed, low in energy consumption, free of noise and convenient to operate. In the lead smelting and pumping processes, the liquid level of the molten lead in the lead smelting furnace has no fluctuation except ascending and descending in parallel, an oxidation protective coating of the liquid level is immobile, contact oxidation between the molten lead in the lead smelting furnace and the outside is well stopped, and the lead oxidization loss in the process can be controlled to be 2% or below.
Description
technical field [0001] The invention relates to a pneumatic pump lead device for the manufacture of lead-acid batteries, which belongs to the field of lead-acid battery manufacture. Background technique [0002] Lead-acid batteries are widely used in backup power supply, energy storage, power energy and other fields by virtue of their excellent performance-price ratio. Although lithium batteries have been developed by leaps and bounds in recent years, due to their high prices and safety needs to be improved, it will be difficult to shake the leading position of lead-acid batteries in the field of secondary batteries for quite a period of time. [0003] The biggest problem with lead-acid batteries is the pollution of the environment by lead, the main material. During the production process of lead-acid batteries, about 5% of the lead is directly oxidized into lead slag, and a large part of this lead slag is discharged into the atmosphere and water bodies in various forms suc...
