Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically to a high-efficiency and energy-saving casting machine for lead liquid. Background Technology

[0002] Currently, most smelters use the following process for casting lead anode plates: crude lead is melted and copper removed in a copper stripping pot, and the molten lead is pumped from the pot to the casting tank of the anode plate casting unit. Due to site limitations, a long lead molten lead chute pipeline is required from the pot to the casting tank. Because of the poor heat dissipation of the pipeline, it is impossible to ensure that the lead temperature is controlled within the melting range for casting, resulting in poor fluidity, pipe blockage, or slag formation. Furthermore, existing casting machines dissipate heat during operation, leading to heat loss and energy waste. To improve this situation, a high-efficiency and energy-saving lead molten lead casting machine is proposed.

[0003] As disclosed in the authorization announcement number CN221516077U, an energy-saving alloy liquid casting machine includes a support arm, a motor is fixedly connected to the side wall of the support arm, a rotating column is fixedly connected to the output end of the motor, and a casting barrel is fixedly connected to the other end of the rotating column through the side wall of the support arm. A material blocking component that blocks the discharge port of the casting barrel is fixedly connected to the side of the support arm facing the casting barrel. Although it achieves the goal of preventing spillage from the casting barrel by using a casting barrel, hopper, baffle one, and baffle two, and the mutual shielding of baffle one and baffle two in conjunction with the height of the hopper when the support arm is transferred, the structure is simple. With the setting of motor, rotating column, and baffle assembly, when the casting barrel is kept upright during transfer, the block of the baffle assembly blocks the outlet of the guide cylinder, avoiding the risk of high-temperature aluminum liquid spilling out of the guide cylinder. When the casting barrel is tilted, the outlet of the guide cylinder automatically disengages from the block, and the high-temperature aluminum liquid flows out of the guide cylinder for casting. It has high safety, saves energy, and has low operating costs. However, this does not solve the problem that existing casting machines are not conducive to the circumferential rotation of the casting machine to scrape and clean the lead slag on the surface of the molten lead, nor to the quick disassembly and assembly of the liquid storage chamber and aluminum block fins, which affects the purity of the molten lead and the convenience of maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency and energy-saving lead liquid casting machine to solve the problems mentioned in the background art, such as the casting machine being inconvenient to rotate and scrape the lead slag on the surface of the lead liquid, which is not conducive to the quick disassembly and assembly of the liquid storage chamber and aluminum block fins, thus affecting the purity of the lead liquid and the convenience of maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving lead casting machine, comprising a smelting crucible and a liquid outlet pipe. The liquid outlet pipe is installed on the side wall of the smelting crucible. Turbofan generators are symmetrically arranged on the side wall of the smelting crucible above the liquid outlet pipe. Connecting pipes are installed at the bottom ends of the turbofan generators, and liquid storage chambers are installed at the bottom ends of the connecting pipes. A connecting shaft is provided on the side of two sets of liquid storage chambers that are close to each other. The liquid storage chambers are movably connected through the connecting shafts. Furthermore, one set of liquid storage chambers... A connecting block is symmetrically installed at the top, and a plug-in seat is symmetrically installed at the top of another set of liquid storage chambers. Aluminum block fins are installed on the inner wall of each liquid storage chamber. A plug-in post is installed on the side wall of each connecting block, and the surface of the plug-in post is provided with a groove. A limit ring is provided on the side wall of each plug-in seat. A limit post is slidably installed inside each limit ring. A spring is provided on the surface of each limit post, and the two ends of the spring are respectively connected to the limit post and the limit ring. A support seat is provided on the outside of the melting crucible.

[0006] Preferably, the top of the smelting crucible is symmetrically provided with L-shaped frames, and the bottom of each L-shaped frame is equipped with a second hydraulic rod.

[0007] Preferably, the output end of the second hydraulic rod is equipped with a second push arm, and the inside of the smelting crucible is provided with a support frame, which is connected to the second push arm.

[0008] Preferably, the top of the support frame is provided with a placement seat, and a servo motor is provided inside the placement seat.

[0009] Preferably, a drive shaft is installed at the output end of the servo motor, and scraper frames are symmetrically arranged at the bottom end of the drive shaft.

[0010] Preferably, a first hydraulic rod is movably mounted on the side wall of the bearing seat, and a first push arm is mounted on the output end of the first hydraulic rod.

[0011] Preferably, a linkage block is provided at the end of the first push arm away from the first hydraulic rod, and a hinge shaft is provided at the end of the linkage block near the first push arm, and the linkage block is movably connected to the first push arm through the hinge shaft.

[0012] Preferably, a linkage shaft is fixedly installed at the end of the linkage block away from the first push arm, and the linkage shaft is movably connected to the bearing seat and connected to the melting crucible.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the casting machine not only realizes the circumferential rotation to scrape and clean the lead slag on the surface of the lead liquid, and facilitates the quick disassembly and assembly of the liquid storage chamber and aluminum block fins, but also improves the purity of the lead liquid and the convenience of maintenance.

[0014] (1) Place the lead block in the melting crucible and heat the melting crucible to melt the lead block into lead liquid. Impurities in the lead block will form lead slag that floats on the surface of the lead liquid. In order to avoid the lead slag affecting the quality of the lead liquid, the second hydraulic rod drives the second push arm to move downward. The second push arm drives the support frame and scraper frame to move downward, so that the lower half of the scraper frame is immersed in the lead liquid. The servo motor drives the scraper frame to rotate clockwise through the drive shaft to scrape the lead slag floating on the surface of the lead liquid through the opening of the scraper frame into the scraper frame and collect it, thereby improving the purity of the lead liquid. The first hydraulic rod drives the first push arm to move. The first push arm drives the linkage block to rotate through the hinge shaft. The linkage block drives the melting crucible to rotate through the linkage shaft. The melting crucible rotates and tilts. Under the action of gravity, the lead liquid is discharged through the liquid outlet pipe into the mold to complete the casting of the lead liquid. This realizes the circumferential rotation to scrape and clean the lead slag on the surface of the lead liquid, which facilitates the tilting discharge of the lead liquid and ensures the purity of the lead liquid.

[0015] (2) The heat from the lead liquid flowing through the outlet pipe is conducted through the outlet pipe and aluminum block fins to the interior of the storage chamber, heating the water inside the storage chamber to form steam. The steam enters the turbofan generator through the connecting pipe, driving the turbofan blades inside the turbofan generator to rotate and generate electricity, thereby recovering and utilizing this part of the heat, reducing resource waste and saving energy. If the storage chamber needs to be quickly disassembled, the limiting post is pulled out, and the limiting post slides inside the limiting ring, which is in the limiting fit of the limiting ring. Next, the limiting post squeezes the spring and pulls the limiting post out of the groove on the surface of the plug-in post, separating the plug-in post from the plug-in seat. The connecting block moves, and the connecting block drives the plug-in post to be pulled out from inside the plug-in seat. The liquid storage chamber is rotated, and the liquid storage chamber rotates around the connecting shaft to remove the liquid storage chamber from the surface of the liquid outlet pipe. After the liquid storage chamber and aluminum block fins are maintained, the above operation is repeated in reverse to install them back onto the surface of the liquid outlet pipe. This achieves quick disassembly and assembly of the liquid storage chamber and aluminum block fins, improving the convenience of maintenance of the liquid storage chamber and aluminum block fins.

To prevent the lead slag from affecting the quality of the molten lead, the second hydraulic rod 9 is opened, which drives the second push arm 10 to move downward. The second push arm 10 then drives the support frame 11 and the scraper frame 14 to move downward, immersing the lower half of the scraper frame 14 into the molten lead.

The heat is conducted to the interior of the liquid storage chamber 18, heating the water inside to form steam. The steam enters the interior of the turbofan generator 15 through the connecting pipe 17, driving the turbofan blades inside the generator 15 to rotate and generate electricity.
