Description

[0002] As the most economical and greenest grid production method at present, the continuous casting technology of lead -acid battery grid has been generally recognized by lead -acid battery manufacturers. Since the continuous casting production line has a large output per unit time, it needs to consume more lead liquid, and therefore the demand for the lead melting furnace for supplying lead to the continuous casting mold is higher.

[0003] The traditional lead melting furnace is purely heated by electric heating pipes or natural gas. When heated by electric heating pipes, the lead liquid can be uniformly heated by uniformly arranging the heating pipes, and since the heating by electric heating pipes is relatively mild, the temperature of the lead liquid can be controlled within a relatively narrow range to achieve accurate control of the temperature of the lead liquid. Compared with heating by electric heating pipes, heating by burning natural gas with a burner is lower in cost, but the lead liquid is not uniformly heated, and it is difficult to accurately control the temperature by burning natural gas. Since the demand for the lead melting furnace of the continuous casting production line is high, if electric heating pipes are used alone, high-power electric heating pipes need to be configured, which is too high in production cost; if the burner is used alone to burn natural gas, it is impossible to achieve accurate control of the temperature of the lead liquid, and at the same time, the demand for lead supply to the continuous casting mold requires a high purity of the lead liquid, and the traditional single heating furnace does not have a suitable filtering structure for the lead liquid, resulting in many production defects of the lead -acid battery grid.

[0025] In the embodiment, the transition lead pump is fixedly installed on the lead melting furnace mechanism 1 through the rack 24, the output end of the lead delivery pipe 15 is connected and installed through cooperation with the lead flow box assembly, and lead liquid is output through the transition lead pump.

[0027] In this embodiment, the lead flow box assembly includes a lead flow box 12 installed in the lead supply furnace mechanism, a lead flow filter screen 13 installed in the lead flow box 12, and a filter screen positioning block 121 matched with the lead flow filter screen 13, which is fixedly installed with the lead supply furnace mechanism. As shown in Figure 4 The lead flow box 12 can be provided as a cuboid structure, and the lead flow box 12 is provided with a lead passing opening at the front end, and the lead flow filter screen 13 is installed on the lead supply furnace mechanism through the filter screen positioning block 121.

[0028] In this embodiment, the lead flow box 12 is provided with a lead passing opening matched with the lead flow filter screen at the front end, the filter screen positioning block is provided with a positioning waist-shaped hole, the lead supply furnace mechanism is provided with a lead flow box positioning block 122 matched with the filter screen positioning block for fixed installation, and the lead flow box positioning block is provided with a plurality of strip-shaped grooves 123. The lead flow box 12 is fixedly installed with the filter screen positioning block 121, the filter screen positioning block 121 and the lead flow box positioning block 122 are matched and installed with bolts or screws, and after the positioning waist-shaped hole and the strip-shaped grooves 123 are aligned, they can be tightened with locking screws. Of course, the strip-shaped grooves 123 are provided with a plurality of strip-shaped grooves 123, which facilitates the position adjustment of the filter screen positioning block 121, and a plurality of filter screens can also be arranged on the filter screen positioning block 121, forming a multi-layer filter screen filtering effect, and further improving the purity of the lead liquid.

[0029] In this embodiment, the lead flow box assembly 1 and the lead supply furnace mechanism 7 are provided with an overflow tank 4. When the extraction speed of the transition lead pump and the extraction speed of the lead supply lead pump are not matched or there are other faults, causing the speed of the transition lead pump to the lead supply furnace to be always greater than the speed of the lead supply lead pump to the continuous casting mold, the excess lead liquid can flow back to the lead melting furnace mechanism 1 through the overflow tank, avoiding excessive lead liquid from flowing out.

[0030] In this embodiment, the lead melting furnace mechanism 1 and the lead supply furnace mechanism 7 are both provided with temperature detection devices 3 matched for use. Of course, the two furnace mechanisms are also provided with liquid level detection mechanisms 8 and an overall control center 9, which facilitates the operation of the lead melting furnace mechanism 1 and the lead supply furnace mechanism 7 (the detection mechanisms and the control center are all adopted in the prior art, and will not be described here).

[0031] The whole device is implemented as follows: the lead ingot and the corner material generated in the production process of the grid are transported into the lead melting furnace, the burner melts the lead ingot and the corner material by burning natural gas, when the temperature of the lead liquid in the lead melting furnace reaches the set value (usually slightly lower than the temperature of the lead liquid in the lead supply furnace), the temperature detection device 3 feeds back the data to the control center 9, and the control center 9 controls the burner 11 to stop working, when the temperature is lower than the set value, the temperature detection device 3 feeds back the data to the control center 9, and the control center 9 controls the burner 11 to start working again.

[0032] The transition lead pump in the lead melting furnace works at a set speed, and the lead liquid in the lead melting furnace is pumped to the bottom of the lead flow box 12 in the lead supply furnace. The two filter screens at the bottom of the transition lead pump and the gap in the upper part of the lead flow box 12 can effectively filter the impurities in the lead liquid. The lead flow box in the lead supply furnace is arranged as far away from the lead supply pump as possible, and the lead liquid flows from the bottom of the lead flow box 12 to the lead flow opening in the upper part, and then to the lead supply pump. The farther the lead liquid flows, the longer the lead liquid stays in the lead supply furnace, and the more accurately the temperature of the lead liquid can be controlled. The lead supply pump pumps the lead liquid in the lead supply furnace into the continuous casting mold for casting.

[0033] When the temperature of the lead liquid in the lead supply furnace is higher than the set value, half of the electric heating pipes stop working, and the other half continue to work to keep the lead liquid warm. When the temperature of the lead liquid in the lead supply furnace is lower than the set value, all the electric heating pipes start working to heat the lead liquid.

[0034] The lead liquid surface of the lead melting furnace is set with three positions of the highest point, the middle point and the lowest point, and the liquid level detection mechanism 8 can sense the position of the lead liquid surface and transmit the data to the control center 9. Whether it is a lead melting furnace or a lead supply furnace, when the lead liquid surface is at the highest point or the lowest point, the control center 9 sends an alarm to remind the worker to check and troubleshoot.

[0035] Of course, the second conveying method can also be used between the lead melting furnace mechanism 1 and the lead supply furnace mechanism 7, that is, a communication pipe 16 can be welded between the lead melting furnace and the lead supply furnace, and the lead liquid flows from the lead melting furnace to the lead supply furnace through the communication pipe 16. At this time, a mounting hole is opened at the bottom of the lead flow box 12 for the communication pipe 16 to pass through, one end of the communication pipe 16 is in the lead melting furnace, and the other end penetrates into the bottom of the lead flow box 12 in the lead supply furnace. The lead liquid in the lead melting furnace flows through the communication pipe 16 to the bottom of the lead flow box 12, and then flows out through the lead flow opening above the lead flow box 12. At this time, the transition lead pump can be cancelled, the system control of the control center 9 will be simpler, and there will be no overflow phenomenon, but compared with using the transition lead pump to pump the lead liquid, the impurities brought into the lead supply furnace will be more, that is, the purity of the lead liquid will decrease, and the user can choose the appropriate method according to the quality requirements of the grid.

[0036] In use, since the lubrication points of the lead pump are above the lead liquid level in the lead melting furnace, it is inconvenient to add lubricating oil, and workers are also prone to be scalded, so workers are not willing to add lubricating oil to the lubrication points of the lead pump, which leads to the bearings at the lubrication points of the lead pump being prone to damage. Therefore, a manual lubricating pump 10 is also configured for each lead pump on the lead melting furnace, and the manual lubricating pump 10 and each lubrication point of the lead pump are connected through copper pipes, and workers can add lubricating oil to the manual lubricating pump 10 at one time, and can easily add lubricating oil to the lubrication points of the lead pump by pressing the manual pump handle.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
