Abstract

The invention discloses a five-hammer release machine which comprises a clamping mechanism used for positioning an anode scrap group and a hammer driving mechanism used for releasing and impacting the anode scrap group. The driving hammer mechanism comprises a loosening machine bottom frame and a plurality of loosening impact units which are arranged on the loosening machine bottom frame and right face the anode scrap set. After the catenary structure drives the guide rod group connected with the anode scrap carbon block to reach the working area, the guide rod clamping mechanism can position the guide rod group, and the carbon scrap clamping mechanism can fix the anode scrap carbon block. Then, a guide rail on the lower portion of the releasing machine pushes the five hammer heads to an electrolyte hard shell near a steel claw, and the cylindrical sliding block is fixed through a pawl clamping structure. And the five hydraulic hammers are controlled by the same oil path to impact the electrolyte hard shell. The same hydraulic oil way and the same hammering surface area at the two ends enable the two ends of the anode scrap to be stressed in a balanced mode, extra torque cannot be generated, and therefore the problem that a guide rod set and a steel claw deform greatly is effectively solved.

[0002] In the current aluminum electrolysis industry, electrolyte crust is easily formed on the surface of the anode. In the scrap assembly workshop, in order to recover the scrap carbon blocks and ferrophosphorus, electrolyte loosening equipment is needed to clean the electrolyte crust on the steel claws. However, the current loosening process of the scrap electrolyte is carried out by the loosening equipment as a whole, but the electrolyte crust is not evenly distributed. In this case, the impact force in the loosening process is unbalanced, and it mainly relies on a large number of positioning and clamping equipment to fix the scrap carbon blocks and guide rod groups to offset the impact force. This results in additional torque on the clamping equipment and guide rod groups, which in turn damages them and reduces their service life. Summary of the invention

[0036] In this embodiment, an oil passage 16 is provided on the impact hammer 181, which can be connected to the oil passages of other hammers. An impact push rod 17 is installed at the front end of the hammer, and a dust ring is provided between the impact push rod 17 and the telescopic impact assembly 18. The impact push rod 17 is connected to the punch 20 through a limit groove 19, and a cover is provided at the slot 19 and the punch 20, and a sealing design is performed.

[0037] like Figure 2 and Figure 3As shown, in this embodiment, the hammer adjustment slide 2 includes a guide rail 22 installed on the loosening machine base 3, a cylindrical slider 21 limitedly installed on the guide rail 22, and a support plate I installed on the cylindrical slider 21 and used to install multiple telescopic impact assemblies 18; wherein a pawl 24 is installed on the cylindrical slider 21 by a fastening bolt IV 23, and a ratchet bar 25 adapted to the pawl 24 is installed on the loosening machine base 3.

[0038] Specifically, the hammer adjustment slide 2 is distributed on both sides of the residual pole, and a bolt hole is opened on the top for fixing the hammer mechanism. Two cylindrical sliders 21 are respectively provided at the lower part of the base 2, and sealing rings are provided on both sides of the sliders, which can move on the guide rails 22. A ratchet 24 is installed at the end of the cylindrical slider 21 through a fastening bolt 23, and a ratchet bar 25 is fixed to the loosening machine base frame 3 through a fastening bolt and meshes with the ratchet 24.

[0039] like Figure 4 As shown, in this embodiment, the loosening machine chassis 3 includes a support plate II and a plurality of columns 31 installed at the bottom of the support plate II; wherein the two ends of the guide rail 22 are installed on the support plate II through bushings 33 or support plates; wherein a dustproof plate 35 close to the residual pole group 6 is installed on the support plate II; wherein a through hole 36 is opened on the dustproof plate 35 to facilitate the passage of the impact push rod 17.

[0040] Specifically, the guide rail 22 is installed on the loosening machine chassis 3 through a shaft sleeve 33, and the shaft sleeve 33 can be disassembled and moved on the loosening machine chassis 3 through a fastening bolt 34. The dustproof plate 35 has a through hole 36 to allow the impact push rod 17 and the punch 20 to pass through, and the bottom of the dustproof plate is fixed to the loosening machine chassis using a fastening bolt 37.

[0041] like Figure 7 As shown, the butt group 6 includes a butt carbon block 63 and a top guide rod 61 connected to the butt carbon block 63 via a steel claw 62. The clamping mechanism includes a butt carbon clamping mechanism 4 and a guide rod clamping mechanism 5.

[0042] like Figure 5 As shown, the residual carbon clamping mechanism 4 includes a cylinder-driven clamping arm 42 installed between the residual carbon block 63 and the loosening machine frame 3, an adjusting cylinder for adjusting the cylinder-driven clamping arm 42 to be close to the residual carbon block 63, a plurality of hydraulic support arms 43 installed on the cylinder-driven clamping arm 42, and a perforated anti-skid plate 44 installed at the telescopic end of the hydraulic support arm 43; wherein a coarse positioning cylinder Ⅰ32 for adjusting the position of the cylinder-driven clamping arm 42 is installed on the loosening machine frame 3 on one side of the residual carbon block 63; and a coarse positioning clamping cylinder 41 for adjusting the position of the cylinder-driven clamping arm 42 is installed on the loosening machine frame 3 on the other side thereof.

[0043] When in use, the carbon residue clamping mechanism 4 is symmetrically distributed on both sides of the anode butt 6, and includes six coarse positioning clamping oil cylinders 41, which push the clamping arms 42 to coarsely position the anode butt carbon block 63. Ten hydraulic support arms 43 are arranged inside the clamping arms 42, and anti-slip plates 44 with holes are installed at the ends of the support arms 43 to accurately position the anode butt carbon block.
