Description

Technical Field

[0001] The invention relates to the technical field of lead-acid battery manufacturing, in particular to a lead-acid battery lead melting furnace device. Background Art

[0002] The plate is the main component of the lead-acid battery. The plate stores electrical energy when the battery is charged and releases electrical energy when the battery is discharged. It can be cycled repeatedly, thus forming the charge and discharge function of the lead-acid battery. The plate consists of two parts: the grid and the active material. The grid is the skeleton structure of the plate, which is used to conduct electricity and support the active material. When manufacturing the grid, the alloy lead needs to be melted first, and then the lead liquid is pumped into the grid casting machine using a lead pump. Because lead is easily oxidized at high temperatures, the alloy lead will form an oxide layer on its surface during the melting process. The oxide layer needs to be salvaged in time, otherwise it will form lead slag, which will block the lead pump in the lead melting furnace, causing the lead pump to fail to operate normally or be damaged, and the lead slag passing through the lead pump will reduce the product quality.

[0003] At present, the industry usually adopts the method of frequently salvaging lead slag to prevent lead slag from entering the lead pump for melting alloy lead. In the process of salvaging lead slag, lead slag will be produced when the lead liquid comes into contact with the air. In this way, the more frequent the lead slag salvage, the more likely it is to cause lead oxidation, which not only causes waste, but also has high work intensity and high production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a lead-acid battery lead melting furnace device, which overcomes the defects in the prior art, avoids damage or blockage of the lead pump, reduces maintenance costs, improves production efficiency, and does not require frequent salvage of lead slag in the lead melting pot, reduces the contact between lead liquid and air, thereby reducing the generation of lead slag and improving the quality of finished products.

[0029] Combination Figure 1~Figure 3 It can be seen that the present embodiment provides a lead-acid battery lead melting furnace device, including a lead melting furnace 1, in which a lead melting pot 101 is provided, and also including a heat preservation furnace 2, which is fixedly arranged on one side of the lead melting furnace 1, and in which a heat preservation pot 201 and a lead pump 202 are provided, and a lead passage 3 is provided between the heat preservation pot 201 and the lead melting pot 101, and a valve 301 and a filter element 302 are provided in the lead passage 3, and the output port of the lead pump 202 is connected to a lead outlet pipe 206, and the discharge end of the lead outlet pipe 206 extends to the outside of the heat preservation furnace 2. By connecting the insulation furnace 2 next to the lead melting furnace 1, the lead liquid in the lead melting furnace 1 is first melted and then flows into the insulation pot 201, and a valve 301 and a filter 302 are installed on the lead passage 3, so that lead slag cannot enter the insulation pot 201. By installing a lead pump 202 in the insulation pot 201, it is possible to prevent lead slag from entering the lead pump 202, thereby avoiding damage or blockage of the lead pump 202, reducing maintenance costs, and improving production efficiency.

[0030] The lead pump 202 includes a second drive motor 205 disposed above the insulation pot 201, a lead pump shaft 204 connected to the output end of the second drive motor 205 and disposed in the insulation pot 201, and a lead pump body 203 disposed at the bottom end of the lead pump shaft 204, and the output port of the lead pump body 203 is connected to the lead outlet pipe 206. Preferably, the lead inlet of the lead pump body 203 is attached to the bottom of the insulation pot 201, and the horizontal height of the bottom of the insulation pot 201 is lower than the height of the bottom end of the outlet of the lead passage 3.

The molten lead is filtered before entering the insulation pot 201, and the lead slag left in the lead melting furnace 1 after filtering has little impact on subsequent production. Therefore, the lead slag in the lead melting pot 101 can be avoided as much as possible, which not only reduces the work intensity, but also reduces the contact between the molten lead and the air, thereby reducing the generation of lead slag and improving the molding quality of the continuous casting grid.

[0032] The filter element 302 is detachably connected to the discharge port of the lead passage 3. A filter element slot 303 is provided at the discharge port of the lead passage 3, and the filter element 302 is engaged in the filter element slot 303.

Lead slag usually floats on the surface of the lead liquid. The filter element 302 is installed on the side close to the insulation pot to improve the product quality and purity, and the detachability of the filter element 302 is realized, so that the filter screen 305 does not need to be replaced and repaired on the side close to the high-temperature lead melting furnace 1. The valve 301 is closed before replacement, which improves the safety of maintenance and facilitates later maintenance and replacement.

[0033] The filter element 302 and the filter element groove 303 can also be arranged at the feed port of the lead passage 3 to reduce the scratches on the valve 301 by the lead slag.

The heating element 208 is preferably an electric heating tube group. When the insulation pot 201 is running, heating and heat preservation can be performed to prevent the lead liquid in the insulation pot 201 from condensing, affecting the extraction of the lead liquid by the lead pump 202, and improving the melting efficiency of the lead liquid.

[0035] The bottom of the lead melting pot 101 is provided with a concave spherical surface 109, and the lead passage 3 is arranged on the pot wall above the concave spherical surface 109. The lead block can fall and accumulate in the concave spherical surface 109 due to its own weight. The lead passage 3 is arranged on the pot wall above the concave spherical surface 109 to reduce the situation that the lead slag blocks the filter 305, and can increase the heating area, so that the burner 106 can heat the bottom of the lead melting pot 101 and improve the melting effect of the lead block.

The edge of the fin 210 is connected to the surface of the lead melting furnace 1 by bolts.

[0037] The upper and lower ends of the fins are provided with connecting parts 209, and the connecting parts 209 are fixedly connected to the lead melting furnace 1 by bolts, so as to facilitate the installation between the lead melting furnace 1 and the insulation furnace 2 and improve the firmness of the insulation furnace 2.

[0038] The lead melting furnace 1 is provided with a stirrer 102, and a burner 106 is provided below the lead melting pot 101. The lead bars put into the lead melting pot 101 are melted.

[0039] The stirrer 102 includes a first drive motor 105 disposed above the lead melting pot 101, a stirring shaft 104 connected to the output end of the first drive motor 105 and vertically disposed in the lead melting pot 101, and a stirring blade 103 disposed at the bottom end of the stirring shaft 104. The stirring by the stirrer 102 accelerates the melting of the alloy lead strip.

[0040] The insulation furnace 2 is fixedly connected to the lead melting furnace 1 by bolts. A lead inlet 107 is provided on the top of the lead melting furnace 1, and a sealing cover 108 adapted thereto is provided on the lead inlet 107.

[0041] The working principle of a lead-acid battery lead melting furnace device provided by the present invention is as follows: alloy lead bars are added into the lead melting pot 101 from the lead inlet 107, and the alloy lead bars are melted into lead liquid under the heating action of the burner 106, and stirred by the stirrer 102 to accelerate the melting of the alloy lead bars and promote the uniformity of the alloy composition, and then the lead liquid is filtered through the lead passage 3 and flows into the insulation pot 201 after the flow is controlled, and then the lead liquid is pumped from the insulation pot 201 into the lead outlet pipe 206 by the lead pump 202, and the lead outlet pipe 206 is connected to the grid casting machine in the next process to complete the melting of the alloy lead bars.
