Description

Technical Field

[0001] The utility model belongs to the field of lead electrolytic refining, and in particular relates to a quantitative casting device for lead anode plates. Background Art

[0002] The crude lead is added to the pot, melted, slag pressed, stirred, and slag removed to form high-purity lead liquid. The lead liquid enters the disc mold through the flow channel and is cast to form anode plates of certain specifications, and finally participates in the electrolyte anode and cathode electrolysis process.

[0003] However, in traditional lead casting, the lead liquid flows into the casting box through a lead pump, and the time for the lead liquid to flow into the flow channel is set in the hope of obtaining anode plates with the same specifications. However, the lead pump pumps the lead liquid into the casting box, and the lead liquid is impacted by the conveying action of the lead pump, and is in an unstable state in the casting box. As a result, the unequal amounts of lead liquid in the casting box give different pressures to the lead flow outlet, which may also cause flow changes, resulting in uneven thickness of the anode plates. Finally, when the uneven thickness anode plates enter the electrolytic cell for electrolysis, the thinner anode plates complete the electrolysis reaction too early within the specified electrolysis cycle, resulting in incomplete anode plates, and the attached anode mud falls into the electrolyte, contaminating the electrolyte, and ultimately causing the lead precipitation process components to be unqualified. Summary of the Invention

[0004] The utility model aims to solve the problem that, in the process in which the existing lead liquid is pumped into a casting box and then falls into a mold through a flow channel and a lead flow outlet, the lead pump pumps the lead liquid into the casting box, and the unequal amounts of lead liquid in a fluctuating state in the casting box lead to different lead liquid pressures or flow changes, thereby causing uneven thickness of anode plates formed in the mold. The utility model provides a lead anode plate quantitative casting device, which divides the casting box into a first liquid storage hopper and a second liquid storage hopper by a partition, and the lead liquid pumped into the first liquid storage hopper enters the second liquid storage hopper through the liquid outlet, and then the liquid outlet is blocked to achieve quantitative lead liquid, and the flow rate of the lead liquid discharged from the second liquid storage hopper to the flow channel is stable, thereby ensuring that a certain amount of lead liquid flows into each mold within a limited time.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A quantitative casting device for a lead anode plate comprises a casting pot, a casting box and a mold rack, wherein the mold rack is provided with multiple molds, and the mold rack is used to drive the multiple molds to move, a partition is provided in the casting box, and the partition separates the casting box into a first liquid storage hopper and a second liquid storage hopper, a lower end of the partition is provided with a liquid outlet connecting the first liquid storage hopper and the second liquid storage hopper, a drain pipe is provided on one side of the lower end of the second liquid storage hopper, a flow trough is provided below the drain pipe, a lead flow outlet is provided on the lower side of the end of the flow trough away from the drain pipe, and the lead flow outlet is located above the corresponding mold, a conveying pipe is provided between the casting pot and the upper end of the first liquid storage hopper, the conveying pipe conveys the lead liquid in the casting pot to the first liquid storage hopper, and then the lead liquid enters the second liquid storage hopper through the liquid outlet. After completing the quantitative in the second liquid storage hopper, it flows out of the liquid outlet and flows into the flow trough through the drain pipe, and then falls into the mold through the lead flow outlet.

[0007] A stand is fixedly provided above the casting box, and two driving members are fixedly provided on the stand. The output ends of the two driving members are fixedly connected to connecting rods, and the lower ends of the connecting rods are fixedly provided with blocking blocks, which respectively block the liquid outlet and the inlet of the drain pipe. The driving member is used to drive the corresponding blocking blocks to rise and fall, and the lifting and lowering of the two blocking blocks adjusts the switch of the lead liquid flowing from the first liquid storage hopper to the second liquid storage hopper and flowing out of the second liquid storage hopper.

[0008] Preferably, the flow trough includes a first trough body and a second trough body, one end of the second trough body is connected to the middle of the first trough body, and the first trough body arranged horizontally ensures that the lead liquid flowing out of the drainage pipe falls into the flow trough.

[0009] Preferably, a liquid outlet regulating device is further provided above the mold frame, and the liquid outlet regulating device includes a base frame, a bracket, and an regulating driving member. Support arms are relatively provided at one end of the base frame, and a first trough body is rotatably provided between the two support arms away from the end of the base frame. The bracket is fixedly provided on the base frame, and an regulating driving member is fixedly provided on one side of the bracket. The output end of the regulating driving member is hinged to the end of the second trough body close to the base frame, and is used to drive the end of the second trough body close to the base frame to rise and fall. When the end of the second chute is raised, interference with mold replacement is avoided, thereby facilitating mold replacement.

[0010] Preferably, a lead pump is provided on the delivery pipe, and the lead liquid in the casting pot is delivered to the first liquid storage hopper through the delivery pipe by the lead pump.

[0011] Preferably, a reflux groove is provided between the upper end of the first liquid storage hopper and the upper end of the casting pot, and the liquid level of the lead liquid in the first liquid storage hopper is ensured by the reflux groove.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model pumps lead liquid into the first storage hopper, and then the lead liquid enters the second storage hopper through the liquid outlet. After the quantitative amount is completed in the second storage hopper, the liquid outlet is blocked by a block, and the block corresponding to the discharge pipe is removed. The lead liquid in the second storage hopper flows into the flow channel through the discharge pipe and then flows into the mold.

[0014] During this process, since the liquid outlet is blocked, the change in pumping pressure and the fluctuation of lead liquid in the first storage hopper will not affect the lead liquid in the second storage hopper, and the flow rate of lead liquid discharged by the discharge pipe is stable, ensuring the quality of lead anode plate forming;

[0015] During this process, the lead pump continuously delivers liquid lead to the first storage hopper. When the liquid lead level reaches a certain height, it flows back to the casting pot through the reflux trough.

[0016] The utility model effectively ensures the stability of the lead liquid flow rate by setting the second liquid storage hopper, thereby ensuring that the same amount of lead liquid flows into each mold when the residence time in each mold is the same, effectively reducing or even avoiding the problem of uneven thickness of the anode plates formed in the mold.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 5 As shown, this embodiment provides a quantitative casting device for lead anode plates, including a casting pot 1, a casting box 2 and a mold rack 3, wherein a plurality of molds are arranged on the mold rack 3, and the mold rack 3 is used to drive the plurality of molds to move, and the mold rack 3 is disc-shaped. A power device is provided on one side of the mold rack 3 to drive the mold rack 3 to rotate, and a plurality of molds are arranged circumferentially on the mold rack 3. When the mold rack 3 rotates, a new mold is replaced to the bottom of the corresponding lead flow port 21, and the mold rack 3 rotates in a stepping manner, so that each mold stays under the lead flow port 21 for the same time.

[0025] A partition 4 is provided in the casting box 2, and the partition 4 separates the casting box 2 into a first liquid storage hopper 5 and a second liquid storage hopper 6. A liquid outlet connecting the first liquid storage hopper 5 and the second liquid storage hopper 6 is provided at the lower end of the partition 4. The lead liquid in the first liquid storage hopper 5 enters the second liquid storage hopper 6 through the liquid outlet. A drain pipe 7 is provided on one side of the lower end of the second liquid storage hopper 6. A flow trough is provided below the drain pipe 7. The lead liquid in the second liquid storage hopper 6 flows out through the drain pipe 7 and falls into the flow trough. A lead flow port 21 is provided on the lower side of one end of the flow trough away from the drain pipe 7. The lead flow port 21 is located above the corresponding mold, and the lead liquid in the flow trough falls into the mold below it through the lead flow port 21.

[0026] A delivery pipe 8 is provided between the casting pot 1 and the upper end of the first liquid storage hopper 5, and a lead pump 19 is provided on the delivery pipe 8. The lead liquid in the casting pot 1 is then transported to the first liquid storage hopper 5 through the delivery pipe 8 under the action of the lead pump 19. A reflux groove 20 is provided between the upper end of the first liquid storage hopper 5 and the upper end of the casting pot 1. The reflux groove 20 ensures that the liquid level of the lead liquid in the first liquid storage hopper 5 is stable, and avoids the lead liquid continuously transported into the first liquid storage hopper 5 by the lead pump 19 from rising or even overflowing when the liquid outlet is blocked.

[0027] A stand 9 is fixedly provided above the casting box 2, and two driving members 10 are fixedly provided on the stand 9. The driving members 10 are oil cylinders. The output ends of the two driving members 10 are fixedly connected to connecting rods 11, and the lower ends of the connecting rods 11 are fixedly provided with blocking blocks 12. The two blocking blocks 12 respectively block the liquid outlet and the inlet of the drain pipe 7. The driving member 10 is used to drive the corresponding blocking blocks 12 to rise and fall. The lifting of the blocking blocks 12 realizes the opening and closing of the liquid outlet and the drain pipe 7 (i.e., whether they are blocked or not).

[0028] The flow trough includes a first trough body 13 and a second trough body 14. One end of the second trough body 14 is connected to the middle of the first trough body 13. The first trough body 13 is located directly below the drain pipe 7. The extended length of the first trough body 13 ensures that all the lead liquid flowing out of the drain pipe 7 falls into the first trough body 13 to avoid leakage. A lead flow outlet 21 is provided on the lower side of one end of the second trough body 14 away from the first trough body 13.

[0029] A liquid outlet regulating device is also provided above the mold frame 3, and the liquid outlet regulating device includes a base frame 15, a bracket 16, and an adjusting drive member 17. A support arm 18 is relatively provided at one end of the base frame 15, and a first trough body 13 is rotatably provided between the two support arms 18 away from the end of the base frame 15. The first trough body 13 is located below the discharge pipe 7, and a bracket 16 is fixedly provided on the base frame 15. An adjusting drive member 17 is fixedly provided on one side of the bracket 16. The adjusting drive member 17 is a cylinder, and the output end of the adjusting drive member 17 is hinged to the end of the second trough body 14 close to the base frame 15, and is used to drive the end of the second trough body 14 close to the base frame 15 to rise and fall. When the lead liquid in the mold below the lead flow port 21 is full, the outflow end (i.e., the lead flow port 21) of the second trough body 14 is driven to rise by the adjusting drive member 17 to avoid interference between the position of the lead flow port 21 of the second trough body 14 and the mold. Then the mold frame 3 drives the mold to move and replaces the empty mold below the lead flow port 21 with a new one.

[0030] As an implementable embodiment, the output end of the adjusting drive member 17 is hinged to the end of the second trough body 14 by a connecting member, and the connecting member includes an ear plate and an annular rod. The second trough body 14 is fixedly provided with an ear plate at one end away from the first trough body 13, and the annular rod is an annular round rod. The two ends of the annular rod respectively rotate through the ear plate and the output end of the adjusting drive member.

[0031] As an implementable embodiment, a track is provided on the mold frame 3, and the base frame 15 is a movable trolley structure. The wheels of the base frame 15 are located in the track. When the mold frame 3 rotates to replace the mold below the lead flow port 21, the base frame 15 moves in the opposite direction of the rotation direction of the mold frame 3 to ensure that the first trough body 13 corresponds to the upper and lower sides of the drain pipe 7.

[0032] When in use, the driving member 10 is first used to raise the block 12 corresponding to the liquid outlet, thereby connecting the first liquid storage hopper 5 with the second liquid storage hopper 6, and driving the block 12 corresponding to the drain pipe 7 to fall, thereby blocking the drain pipe 7;

[0033] The lead liquid in the casting pot 1 is then transported to the first storage hopper 5 by the lead pump 19. The lead liquid in the first storage hopper 5 enters the second storage hopper 6 through the liquid outlet. When the lead liquid levels in the first and second storage hoppers 5 and 6 reach the upper inlet position of the reflux trough 20, the driving member 10 drives the blocking block 12 corresponding to the liquid outlet to fall, blocking the liquid outlet. The lead liquid still pumped into the first storage hopper 5 flows back to the casting pot 1 through the reflux trough 20.

[0034] Then the driving member 10 drives the block 12 corresponding to the drain pipe 7 to rise, the drain pipe 7 opens, the lead liquid in the second liquid storage hopper 6 flows out to the first trough 13, and then passes through the second trough 14 and the lead flow port 21 and falls into the mold. After the mold is full, the corresponding block 12 falls to block the inlet of the drain pipe 7, the adjusting driving member 17 drives one end of the lead flow port 21 of the second trough 14 to rise, and the mold frame 3 rotates to realize the mold replacement under the lead flow port 21. Under normal circumstances, in order to ensure the stability of the lead liquid in the mold, the mold frame 3 The rotation speed is slow, so the chassis 15 moves along the track, and the lead flow outlet 21 is made to correspond to the new empty mold in advance. In this process, the length of the first trough body 13 is used to ensure that the first trough body 13 is always in correspondence with the outlet of the drainage pipe 7. When the lead flow outlet 21 corresponds to the new empty mold, the drainage pipe 7 is opened, and the lead liquid in the second liquid storage hopper 6 flows out of the drainage pipe 7 again until it flows into the new hole mold. As the new mold is continuously replaced, when the lead liquid in the second liquid storage hopper 6 has all flowed out, the above process can be repeated.

[0035] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
