Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an upper pressure stripping mechanism for a residual electrode pressure stripping machine. Background Technology

[0002] During electrolysis, the anode carbon block (or cathode carbon block) will form a "residual electrode" (the part of the carbon block that has not been fully reacted) due to consumption. The residual electrode is tightly bonded to the metal carrier such as the guide rod and steel claw through casting of pig iron or mechanical connection. The residual electrode depressurizer applies directional pressure through a hydraulic / mechanical pressurizing device to separate the residual electrode from the carrier along the bonding surface.

[0003] Chinese utility model patent CN108977852B discloses a phosphorus iron ring pressing and depressing machine, including a frame and a steel claw clamp for clamping steel claws mounted on the frame, and a clamping cylinder for driving the steel claw clamp. The frame has a guide rod channel for the guide rod to enter. A guide structure for guiding the steel claw clamp is provided between the frame and the steel claw clamp. The guide structure includes a guide groove and a guide protrusion. An interval is left between the guide groove and the guide protrusion in the extension direction of the guide rod channel to allow the steel claw clamp to move to adapt to the deformation of the steel claw. The steel claw clamp is connected to the clamping cylinder through a hinge structure extending vertically along the axis and / or the clamping cylinder is connected to the frame through a hinge structure extending vertically along the axis.

[0004] However, most existing fixture assembly blade release structures use a single arc-shaped surface contact method to cooperate with the residual pole. In the actual pressing and releasing process, this structure has the problem that the structures on both sides of the arc-shaped surface of the blade release are relatively thin, which leads to easy wear, cracking and deformation, affecting the continuous operation efficiency of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide an upper pressure stripping mechanism for a residual electrode pressure stripping machine, so as to solve the technical problem of poor stability in the prior art.

[0006] To solve the above problems, the upper pressure stripping mechanism of the residual electrode pressure stripping machine involved in this utility model adopts the following technical solution: This utility model provides an upper pressure stripping mechanism for a residual electrode pressure stripping machine, including a frame, two fixed seats, and two clamping assemblies. The frame has a guide rod channel extending along its front-back direction for the guide rod to pass through. The two fixed seats are symmetrically arranged on the left and right sides of the guide rod channel. The two clamping assemblies correspond one-to-one with the two fixed seats and are symmetrically assembled on the two fixed seats. The front end of the stripping blade of the clamping assemblies has two arc-shaped grooves symmetrically opened in the middle along its width direction. The two arc-shaped grooves are located on the left and right sides of the stripping blade, respectively. One end of each arc-shaped groove extends to the front end face of the stripping blade, and the other end extends to the side wall of the stripping blade on the side where it is located.

[0007] Preferably, the fixture assembly includes a central fixture and side fixtures disposed on both sides of the central fixture. The front end of the central fixture is provided with a release knife, and the front end of the side fixtures is provided with two release knives arranged side by side. The release knives of the central fixture and the release knives of the side fixtures are arranged side by side, and the adjacent arc-shaped grooves of two adjacent release knives cooperate to form a semi-circular arc structure.

[0008] Preferably, the two ejector blades on the side clamp are integrally formed.

[0009] Preferably, the intermediate clamp and its corresponding ejector blade are fixed together by bolts, and the side clamp and its corresponding ejector blade are fixed together by bolts.

[0010] Preferably, the front part of the intermediate fixture is recessed inward to form a first step, and the front end of the first step penetrates the front end face of the intermediate fixture. A cutter is matched and assembled in the first step, and the bottom surface of the cutter is flush with the bottom surface of the intermediate fixture.

[0011] Preferably, the front part of the side clamp is recessed inward to form a second step, and the front end of the second step penetrates the front end face of the side clamp. Two adjacent or integrally formed ejector blades are matched and assembled in the second step, and the front ends of the two ejector blades extend out of the front end face of the side clamp, and the bottom surfaces are flush with the bottom surface of the middle clamp.

[0012] Preferably, the fixed base has a central channel for the intermediate clamp to pass through and two side channels for the side clamp to pass through. The two side channels are symmetrically arranged on both sides of the central channel. The clamp assembly also includes clamping cylinders. A clamping cylinder is mounted on the side of the central channel and the side channels away from the guide rod channel, and is fixed to the fixed base by a cylinder seat. The drive shaft of any clamping cylinder is connected to its corresponding intermediate clamp or side clamp.

[0013] Preferably, it also includes two upper crossbeams symmetrically installed on the left and right sides of the guide rod channel. Each upper crossbeam is located between the guide rod channel and its corresponding fixed seat, and is located on the upper side of the clamp assembly. The bottom of the upper crossbeam is provided with a first structure for sliding cooperation with the clamp assembly, which is spaced along its length. The first structure includes a connecting strip perpendicular to the bottom of the upper crossbeam and a support fixed to the bottom of the connecting strip. The two side walls of the support are symmetrically arranged with the connecting strip as the center line. The top wall of the middle clamp and the top wall of the side clamp are both provided with a sliding groove that passes through both ends of themselves.

[0016] The beneficial effects of this utility model are as follows: This utility model provides an upper pressure stripping mechanism for a residual anode stripper. Two arc-shaped grooves are symmetrically formed along the width direction at the center of the stripper's front end. The arc-shaped grooves of adjacent strippers cooperate to form a semi-circular arc structure. Compared to existing single strippers forming a semi-circular arc surface, due to the limited volume of the anode claw, the thickness of the side walls of the semi-circular arc surface formed by a single stripper is much smaller than the side wall thickness of the semi-circular arc surface formed by two strippers, reducing the probability of cracking and deformation. Simultaneously, the intermediate clamp and side clamps are assembled with the strippers via a first step and a second step, respectively, and are all fixed with bolts. When the stripper wears, it can be quickly replaced simply by removing the bolts, greatly shortening the disassembly and maintenance time and improving the continuous operation efficiency of the equipment.

Detailed Implementation

[0019] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] This utility model provides an upper pressing and depressing mechanism for a residual electrode pressing and depressing machine, including a frame 1, two fixed seats 2, two clamping components 3, and two upper crossbeams 4. The frame 1 has a guide rod channel 11 extending along its front-back direction for the guide rod to pass through. The two fixed seats 2 are symmetrically fixed to the left and right sides of the guide rod channel 11 by bolts. The two clamping components 3 correspond one-to-one with the two fixed seats 2 and are symmetrically assembled on the two fixed seats 2.

[0021] The fixture assembly 3 includes an intermediate fixture 31, side fixtures 32 located on both sides of the intermediate fixture 31, and a clamping cylinder 33. The front end of the intermediate fixture 31 is provided with a release knife 5, and the front end of the side fixtures 32 is provided with two release knives 5 arranged side by side. The two release knives 5 on the side fixtures 32 are integrally formed or attached to each other. The release knives 5 of the intermediate fixture 31 and the release knives 5 of the side fixtures 32 are arranged side by side. Two arc-shaped grooves 51 are symmetrically opened in the middle of the front end of the release knife 5 along its width direction. The two arc-shaped grooves 51 are located on the left and right sides of the release knife 5, respectively. One end of each arc-shaped groove 51 extends to the front end face of the release knife 5, and the other end extends to the side wall of the release knife 5 on the side where it is located. The adjacent arc-shaped grooves 51 of two adjacent release knives 5 are correspondingly matched to form a semi-circular arc structure. The diameter of the semi-circular arc structure is adapted to the outer diameter of the phosphorus iron in the residual carbon cup, which can achieve tight wrapping of the phosphorus iron.

[0022] The intermediate clamp 31 has a first step recessed downwards at its front, with the front end of the first step penetrating the front end face of the intermediate clamp 31. A cutter 5 is fitted into the first step, with the front ends of the cutter 5 extending beyond the front end face of the intermediate clamp 31 and its bottom surface flush with the bottom surface of the intermediate clamp 31. The side clamp 32 has a second step recessed downwards at its front, with the front end of the second step 321 penetrating the front end face of the side clamp 32. Two integrally formed cutters 5 are fitted into the second step, with the front ends of both cutters 5 extending beyond the front end face of the side clamp 32 and their bottom surfaces flush with the bottom surface of the intermediate clamp 31. This ensures that all cutters 5 can simultaneously contact the residual electrode, improving the synchronicity of clamping. The intermediate clamp 31 and its corresponding cutter 5 are fixed with bolts, and the side clamp 32 and its corresponding cutter 5 are fixed with bolts. The bolt connection method is simple and reliable, facilitating the disassembly and replacement of the cutters 5.

[0023] The fixed base 2 has a central channel for the intermediate clamp 31 to pass through and two side channels for the side clamp 32 to pass through. The two side channels are symmetrically arranged on both sides of the central channel. A clamping cylinder 33 is installed on the side of the central channel and the side channel away from the guide rod channel 11, which is fixed to the fixed base 2 by the cylinder seat 34. The drive shaft of any clamping cylinder 33 is connected to its corresponding intermediate clamp 31 or side clamp 32 through a coupling. The clamping cylinder 33 is hydraulically driven.

[0024] Two upper crossbeams 4 are symmetrically mounted on the frame 1 on the left and right sides of the guide rod channel 11 by bolts. Any upper crossbeam 4 is located between the guide rod channel 11 and its corresponding fixed seat 2, and is located on the upper side of the clamping assembly 3. The bottom of the upper crossbeam 4 is provided with a first structure 41 for sliding cooperation with the clamping assembly 3, which is arranged at intervals along its length. The first structure 41 includes a connecting strip 411 perpendicular to the bottom of the upper crossbeam 4 (the connecting strip 411 is integrally formed with the upper crossbeam) and a support 412 fixed to the bottom of the connecting strip 411 by bolts. The two side walls of the support 412 are symmetrically arranged with the connecting strip 411 as the center line. The middle of the top wall of the intermediate clamp 31 and the middle of the top wall of the side clamp 32 are provided with a sliding groove 35 that runs through both ends of the clamp (the direction of the sliding groove 35 is perpendicular to the direction of the guide rod channel 11). The first structure 41 and the intermediate clamp 31 (or the side clamp 32) are slidably limited and engaged by the sliding groove 35. The cross-sectional shape of the sliding groove 35 is adapted to the cross-sectional shape of the mating structure of the drag seat 412 and the connecting bar 411, ensuring the stability of the sliding.

[0025] The top wall of the support 412 is symmetrically fixed with clamping liner plates 6 on both sides of the connecting bar 411. The inner bottom surface of the middle channel is fixed with a first clamping liner plate 7, and the inner bottom surface of the side channel is fixed with a second clamping liner plate 8. The clamping liner plate 6, the first clamping liner plate 7, and the second clamping liner plate 8 are all made of wear-resistant materials, such as high manganese steel, which can effectively reduce the wear of the clamping assembly 3 during the movement.

[0026] Guide bars 9 are bolted to the opposite side walls of the two upper crossbeams 4. Both ends of the guide bars 9 are set as sloping surfaces inclined towards the middle.

[0027] The work process is as follows: The guide rod with the residual electrode is conveyed to the guide rod channel 11 of the frame 1 through the conveying mechanism. Under the guidance of the guide bar 9, the guide rod accurately enters the guide rod channel 11, and the residual electrode is located between the two clamping parts 3.

[0028] The clamping cylinder 33 is activated, and its drive shaft extends, pushing the intermediate clamp 31 and the side clamp 32 to move along the guide rod channel 11 of the first structure 41 until the ejector 5 is in close contact with the residual pole. At this time, the arc-shaped grooves 51 of the adjacent ejector 5 on the same side cooperate to form a semi-circular arc structure, and the arc-shaped grooves of the four adjacent ejector 5 on both sides form a ring.

[0029] The pressure stripping mechanism of the residual electrode press is activated to apply pressure to the residual electrode. Due to the stable clamping of the residual electrode by the stripping blade 5, the connection structure between the residual electrode and the phosphorus iron is destroyed, thus achieving the separation of the residual electrode from the guide rod.

[0030] After the residual electrode is separated, the drive shaft of the clamping cylinder 33 retracts, driving the intermediate clamp 31 and the side clamp 32 to reset, completing one pressing and stripping operation.

[0031] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
