Description

Technical Field

[0001] The invention relates to the field of lead powder production, and in particular to a lead powder production device. Background Art

[0002] Lead powder machines are mainly used in battery production to produce lead powder for grids. Lead powder is an important raw material in battery grid production. With the rapid development of the battery industry, lead-acid battery production technology and equipment have also been rapidly innovated and developed. Among them, lead powder is the main raw material of lead-acid batteries. Its quality directly affects the quality of lead-acid battery products. Therefore, the production process and equipment for manufacturing lead powder have also received more and more attention. In the existing lead powder manufacturing, lead balls or lead blocks are generally sent into the ball mill by a conveyor according to the load. The ball mill is driven by a transmission mechanism and rotates at a certain speed. Due to the action of centrifugal force, the lead balls or lead blocks in the lead powder machine also rotate with the cylinder of the lead powder machine. When brought to a certain height, the lead balls or lead blocks fall freely due to their own weight. In this process, there are three phenomena: (1) The friction between the lead balls or lead blocks and the cylinder generates heat; (2) The friction between the lead balls or lead blocks and the lead balls or lead blocks generates heat; (3) The mutual collision and friction between the lead balls or lead blocks causes the surface grains of the lead balls or lead blocks to deform and slide. The edge of the crystal face where the lead ball or lead block is displaced is oxidized to generate lead oxide. In this process of friction, impact, crystal deformation and displacement, and oxidation, cracks occur between the oxidized part of the surface of the lead ball or lead block and the whole lead ball or lead block. As the cracks gradually deepen, the metal oxide layer gradually falls off from the sphere or block under the action of impact and friction, and then is further ground and pulverized to form fine granular lead powder covered with a layer of lead oxide. However, as the lead block collides in the drum, friction generates heat, and the reaction of lead with oxygen is also an exothermic reaction, which will cause the temperature inside the drum to continue to rise. In addition, the efficiency of generating lead powder due to the irregular rolling of the lead block in the drum needs to be improved. At the same time, the lead powder is produced only by using the friction generated by the friction between the lead block's own gravity and the cylinder. The friction area is small and the production efficiency is low, which cannot meet the production needs. Summary of the invention

At the same time, the extrusion device 5 is provided to extrude the lead block while the lead block moves, so that the friction between the lead block and the circular tube 3 is greater, so that more lead block is rubbed into powder, thereby improving the efficiency of lead powder production. At the same time, the cooling device 8 is provided to cool the circular tube 3 to avoid continuous increase in the temperature inside the circular tube 3, thereby improving the service life of the production device.

[0029] An air inlet fan 9 is fixedly installed on the outside of the box 1, and the output end of the air inlet fan 9 is arranged in the working chamber 104. Fresh air is sent into the box 1 through the air inlet fan 9, which accelerates the oxidation reaction of the lead powder and the air. Under the combined action of the high-speed movement friction heating of the lead block and oxygen, the lead powder is quickly generated. A collecting funnel 10 is fixedly installed on the lower part of the inner wall of the working chamber 104. The collecting funnel 10 is located below the circular tube 3. A collecting box 11 is arranged at the bottom of the working chamber 104.

The partition plate 42 drives the lead block to move in the circular tube 3 while rotating. When the partition plate 42 drives the lead block to fall under the circular tube 3, it rubs against the inner wall of the circular tube 3, so that the surface of the lead block is rubbed into powder, and then passes through the filter hole 32 and undergoes oxidation reaction with oxygen to produce lead powder. The partition plate 42 can also scrape off the lead powder adhering to the inner wall of the circular tube 3, thereby reducing the loss of lead powder production.

[0033] The extrusion device 5 includes a rotating disk 52 and a plurality of arc-shaped extrusion plates 54. The rotating disk 52 is rotatably mounted in the middle of the inner wall of the drum 41.

When the cross groove 7151 moves to be opposite to the cross block 721, under the action of the elastic force of the first spring 722, the cross block 721 enters the cross groove 7151, and then the first connecting rod 715 drives the cross block 721 to rotate, and the cross block 721 drives the hollow cylinder 718 to rotate through the second limiting block 724, and the hollow cylinder 718 drives the first baffle plate 717 to rotate, and the first baffle plate 717 drives the worm 710 to rotate through the first limiting block 723, and the worm 710 drives the worm gear 79 to rotate, and the worm gear 79 drives the first rotating rod 78 to rotate, and the first rotating rod 78 drives the second bevel gear 77 to rotate, and the second bevel gear 77 drives the first bevel gear 76 to rotate, and the first bevel gear 76 drives the second rotating rod 51 to rotate. When the second rotating rod 51 rotates, it drives the extrusion device 5 to extrude the lead block, thereby increasing the friction between the lead block and the inner wall of the round tube 3, thereby increasing the production efficiency of the lead powder.

[0037] The cooling device 8 includes a water pump 81 and a plurality of cooling arc tubes 83. The cooling arc tubes 83 are fixedly installed on the bottom surface of the circular tube 3. The cooling arc tubes 83 are made of metal material to improve the heat exchange efficiency of the cooling arc tubes 83 and the circular tube 3. One end of the cooling arc tube 83 extends through the water inlet cavity 102. The water pump 81 is fixedly installed in the water inlet cavity 102. A water delivery pipe 82 is fixedly installed at the output end of the water pump 81. The water delivery pipe 82 is connected to the cooling arc tube 83. The other end of the cooling arc tube 83 extends through the return water cavity 101. A first connecting pipe 85 is fixedly installed at the rear end of the return water cavity 101. A second connecting pipe 88 is fixedly installed at the rear end of the water inlet cavity 102. The first connecting pipe 85 and the second connecting pipe 88 are fixedly installed with a coil 86. A heat sink 87 is fixedly installed on the outside of the coil 86. When in use, the water inlet cavity 102, the return water cavity 101 and the coil 86 The cooling pipe is filled with cooling water. When working, the water pump 81 transports the cold water in the water inlet chamber 102 to the cooling pipe. The cooling pipe absorbs the heat emitted by the round tube 3. The heat is absorbed by the water, and the cooling water becomes hot water. The hot water is transported to the return water chamber 101. The hot water in the return water chamber 101 is transported to the coil 86 through the first connecting pipe 85. The heat sink 87 dissipates heat and cools the hot water in the coil 86, and then the cooled cold water is transported back to the water inlet chamber 102. When the water flow moves in the water inlet chamber 102, the cooling pipe, the return water chamber 101, and the coil 86, the round tube 3 is continuously absorbed and cooled to avoid excessive temperature of the round tube 3 due to friction with the lead block and oxidation and heating of the lead powder. As a result, the production device as a whole is in a high temperature state under heat transfer, which avoids the entire device working in a high temperature state for a long time and causing a reduction in service life.
