Description

Technical Field

[0001] This utility model relates to the field of equipment technology, specifically to a novel anode vertical mold lead liquid reflux device. Background Technology

[0002] During anode plate production, high-temperature molten lead is pumped from the casting pot to the anode vertical mold holding furnace via a lead pump. Due to the large flow rate of the lead pump, when the flow rate exceeds the casting flow rate of the vertical mold unit, the holding furnace is prone to overfilling and overflowing. Frequently starting and stopping the lead pump to control the molten lead flow rate during this process affects its lifespan. Simultaneously, during anode casting, suspended lead slag is generated on the surface of the molten lead in the holding furnace, which affects the quality of the anode plate. Furthermore, when the vertical mold unit is stopped or under maintenance, the remaining molten lead at the bottom of the holding furnace is prone to clumping due to its low temperature. Continuous heating and heat preservation of the molten lead in the holding furnace is necessary, maintaining the temperature at 370℃-380℃. Prolonged heating and heat preservation consume a significant amount of electrical energy. Therefore, we propose a novel anode vertical mold molten lead reflux device. Summary of the Invention

[0003] The purpose of this invention is to provide a novel anode vertical mold lead liquid reflux device to solve the problems mentioned in the background art.

The lead pump is installed inside the holding furnace to extract and divert the lead liquid in the holding furnace to the anode vertical mold unit. The lead liquid reflux tank returns the lead liquid discharged or overflowing from the holding furnace to the casting pot. The lead liquid outlet discharges the lead liquid into the lead liquid reflux tank. The lead liquid overflow outlet is located on the side of the holding furnace to control the flow rate of the lead liquid in the holding furnace. The lead liquid overflowing from the furnace flows back to the casting pot from the lead liquid reflux tank. The lead liquid casting and conveying pipe is connected to the lead pump and is used to transport the lead liquid in the holding furnace to the anode vertical mold.

[0005] In the above scheme, the furnace is 7100mm long, 580mm wide, and 800mm high.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel anode vertical mold lead melt reflux device has the following advantages:

[0015] 1. The design of a lead molten metal return tank in the furnace can prevent the lead molten metal from overflowing due to the lead pump's delivery flow rate exceeding the vertical mold unit's casting flow rate, thus greatly reducing production costs.

[0016] The lead melt reflux tank designed in the holding furnace can return the suspended lead slag generated on the surface of the lead melt in the holding furnace to the casting pot for slag removal, thus ensuring the quality of the anode plate.

[0017] Incorporating a lead melt reflux tank into the furnace can prevent the reduction of equipment lifespan due to frequent start-stop of the lead pump to control flow.

[0018] The design of a lead melt reflux tank in the holding furnace allows for prolonged heating and insulation of the lead melt, saving a significant amount of electrical energy. Attached Figure Description

The lead pump 6 is installed in the holding furnace 2 to extract and divert the lead liquid in the holding furnace 2 to the anode vertical mold unit. The lead liquid reflux tank 4 returns the lead liquid discharged or overflowing from the holding furnace 2 to the casting pot. The lead liquid discharge outlet 3 discharges the lead liquid into the lead liquid reflux tank 4. The lead liquid overflow outlet 1 is located on the side of the holding furnace 2 to control the flow rate of the lead liquid in the holding furnace 2. The lead liquid overflowing from the furnace 2 returns to the casting pot from the lead liquid reflux tank 4. The lead liquid casting and conveying pipe 8 is connected to the lead pump 6 and is used to transport the lead liquid in the holding furnace 2 to the anode vertical mold.

[0025] In the above scheme, the holding furnace 2 is 7100mm long, 580mm wide, and 800mm high. The function of the holding furnace 2 is to temporarily store and keep warm the high-temperature molten lead extracted from the casting pot.

[0026] In the above scheme, after the heating copper tube 5 is energized, it heats and maintains the lead liquid in the holding furnace 2 at a temperature of 370℃-380℃.

[0027] In the above scheme, the lead pump 6 has a rated power of 4KW and a rotation speed of 1470r / min. Its function is to extract and divert the molten lead in the holding furnace 2 to the anode vertical mold unit.

[0028] In the above scheme, the lead melt return tank 4 has a diameter of 200mm. Its function is to return the lead melt discharged or overflowing from the furnace to the casting pot.

[0029] In the above scheme, the lead liquid discharge outlet 3 has a discharge diameter of 350mm. Its function is to discharge the lead liquid into the lead liquid return tank.

[0030] In the above scheme, the lead molten metal overflow port 1 has an overflow diameter of 400mm.

[0031] In the above scheme, the lead molten casting and conveying pipe 8 has a diameter of 50mm. Its function is to be connected to the lead pump to convey and hold the lead molten lead in the furnace to the anode mold.

[0032] In the above scheme, the lead melt inlet conveying pipe 7 has a diameter of 400mm. Its function is to convey the high-temperature lead melt drawn from the casting pot into the holding furnace.

[0033] In the above scheme, the diameter of the natural gas inlet 9 is 50mm. The function of the natural gas inlet 9 is to melt the lead blocks that have solidified in the lead melt return tank due to excessively low temperature, and to clear the lead melt return tank.

[0034] Working principle:

[0035] Before activating this new type of anode vertical mold lead liquid reflux device, check whether the plugging connecting screw of lead liquid outlet 3 in the figure is tightened to ensure that the outlet is plugged and there is no leakage. The high-temperature lead liquid in the casting pot is transported to the holding furnace 2 in the figure through the lead liquid inlet furnace conveying pipe 7 in the figure by a large lead pump. When the lead liquid level in the holding furnace 2 in the figure reaches a certain value, the lead pump 6 in the figure is started to pump the lead liquid in the holding furnace 2 in the figure through the lead liquid casting conveying pipe 8 in the figure to the anode vertical mold casting mold for anode vertical mold manufacturing. If it is necessary to drain the molten lead from the bottom of the holding furnace 2 shown in the diagram, unscrew the plug on the molten lead outlet 3 shown in the diagram, allowing the molten lead to flow by gravity from the outlet to the molten lead return tank 4 shown in the diagram, located below the holding furnace 2. If the holding furnace 2 is too full, the molten lead will overflow from the molten lead overflow outlet 1 shown in the diagram to the molten lead return tank 4 shown in the diagram. At the same time, the suspended lead slag generated in the holding furnace 2 will also flow back to the casting pot through the molten lead overflow outlet 1 shown in the diagram for slag removal, completing the circulation of molten lead and suspended lead slag in the holding furnace 2 and the casting pot shown in the diagram. Since the temperature of the molten lead in the casting pot is above 400℃, the heating copper pipe 5 shown in the diagram is needed to continuously heat the molten lead in the holding furnace 2 shown in the diagram to prevent the molten lead from condensing at low temperature. As the molten lead in the holding furnace 2 passes through the molten lead return tank 4 shown in the diagram, the temperature drops and lumps form, causing the molten lead return tank 4 shown in the diagram to become blocked. It is necessary to use a homemade oxygen gun connected to the natural gas port 9 shown in the diagram to melt the lumps. By improving the holding furnace 2, a high-low potential is formed between the casting pot and the holding furnace, allowing the lead liquid in the furnace to flow back into the casting pot, achieving the effect of lead liquid reflux and circulation. This can save electricity, reduce equipment lifespan, and lower production costs during production.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
