Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary devices for electrolytic aluminum, and in particular to a shell-removing cylinder hammer head device for removing caulking. Background Technology
[0002] In the electrolytic aluminum production process, a shell-breaking cylinder drives a hammer to break through the shell surface and immerse it in electrolyte before returning. During each entry and exit of the hammer into the electrolyte, electrolyte continuously adheres to the hammer. As the electrolyte cools, large agglomerates form on the hammerhead. These agglomerates can cause excessively large flame holes in the electrolytic cell, leading to excessive heat loss and temperature instability. Furthermore, excessively large agglomerates can block alumina from entering the electrolytic cell, reducing production efficiency, causing voltage fluctuations, and even triggering an anode effect.
[0003] In existing technologies, workers need to break the electrolyte adhering to the surface of the hammer. In order to ensure the output accuracy of the shell-breaking cylinder, it is necessary to disassemble the shell-breaking cylinder and remove the hammer when necessary, which is very troublesome. Some companies add a cylinder or motor to the shell-breaking hammer position for scraping during the design, and also add related control devices. However, due to the limited space above the electrolytic cell, it is difficult to make the effective area of the related equipment large enough, the scraping force is insufficient, and the scraping effect is not obvious. Utility Model Content
[0004] In order to improve the problem of caking on the hammerhead in the above-mentioned background art, this utility model provides a shell-breaking cylinder hammerhead decaking device.
[0005] The shell-breaking cylinder hammer head deburring device provided by this utility model adopts the following technical solution:
[0006] A shell-breaking cylinder hammer head decapsulation device includes a hammer head guide sleeve and a piston rod. The piston rod is driven by a shell-breaking cylinder and slides back and forth within the hammer head guide sleeve. A shell-breaking hammer head is provided at the front end of the piston rod. A sleeve is connected to the front end of the hammer head guide sleeve. The hammer head guide sleeve and the sleeve can improve the guiding accuracy of the hammer head guide sleeve and reduce the downward bending of the piston rod when it extends. The sleeve is connected to a decapsulation device. The shell-breaking hammer head extends out of the decapsulation device and scrapes off the electrolyte adhering to the shell-breaking hammer head by the decapsulation device when it retracts.
[0007] Preferably, the inner circumference of the decapsulator is in close contact with the outer circumference of the shell-breaking hammer, and the front end of the decapsulator is surrounded by a wavy edge cut. The wavy edge cut disperses the scraping force, making it easy to scrape off the adhered electrolytes cleanly.
[0008] Preferably, the sleeve is threadedly connected to and secured to the unpacker, facilitating the replacement of the unpacker.
[0009] Preferably, the outer side of the bag remover is provided with an installation groove.
[0010] Preferably, the rear end of the hammer guide sleeve is surrounded by a mounting flange, and the mounting flange is provided with mounting holes. The hammer guide sleeve is fixedly connected to the end cap provided at the output end of the shell-breaking cylinder through the mounting flange.
[0011] In summary, this utility model has the following beneficial technical effects:
[0012] 1. This utility model provides a device for removing the brittle residue from the hammerhead of a shell-breaking cylinder. A sleeve and a brittle remover are connected to the front end of the hammerhead guide sleeve. After the shell-breaking hammerhead extends out of the brittle remover to open the shell surface and immerse in electrolyte, the electrolyte adhering to the shell-breaking hammerhead is scraped off by the brittle remover when it retracts. No manual cleaning is required, which improves production efficiency.
[0013] 2. This utility model has a simple structure. A wavy cutting edge is provided around the front end of the decapsulator. The wavy cutting edge disperses the scraping force. The cutting edge design makes it easy to scrape off the adhered electrolytes. The decapsulator ensures a large scraping force while occupying a small area. Electrolytes can be scraped off by using the decapsulator. The decapsulator is threaded to the sleeve, which makes it easy to replace the decapsulator. Attached Figure Description

[0022] Reference Figure 2, Figure 3 , Figure 4 A shell-breaking cylinder hammer head decapsulation device includes a hammer head guide sleeve 2 and a piston rod 3. The hammer head guide sleeve 2 is fixed at the output end of the shell-breaking cylinder 1. The output shaft of the shell-breaking cylinder 1 is connected to the piston rod 3 through a connector. The piston rod 3 is driven by the shell-breaking cylinder 1 and slides back and forth in the hammer head guide sleeve 2. The piston rod 3 outputs at the front end of the hammer head guide sleeve 2. A shell-breaking hammer head 4 is provided at the front end of the piston rod 3. A sleeve 5 is connected to the front end of the hammer head guide sleeve 2. The hammer head guide sleeve 2 and the sleeve 5 can improve the guiding accuracy of the hammer head guide sleeve 2 and reduce the downward bending amount when the piston rod 3 extends. The sleeve 5 is connected to a decapsulation device 6. The shell-breaking hammer head 4 extends out of the decapsulation device 6 and scrapes off the electrolyte adhering to the shell-breaking hammer head 4 through the decapsulation device 6 when it retracts.
[0023] Reference Figure 3 , Figure 5 The inner circumference of the decapsulator 6 is in close contact with the outer circumference of the shell-breaking hammer head 4. The front end of the decapsulator 6 is surrounded by a wavy blade slit 7. The wavy slit disperses the scraping force, and the blade design makes it easy to scrape off the adhered electrolyte.
[0024] Reference Figure 3 , Figure 5 The sleeve 5 is threadedly connected to and tightened with the unpacker 6, making it easy to replace the unpacker 6. The unpacker 6 has an installation groove 8 on its outer side. Using an installation wrench, clamp the unpacker 6 in the installation groove 8, twist it, and thread the unpacker 6 to connect and tighten it with the sleeve 5, making it easy to replace the unpacker 6.

The front end of the hammer head guide sleeve 2 is installed with the sleeve 5 and the decapsulation device 6. The front end of the hammer head guide sleeve 2 is aligned with the shell surface. When shell breaking begins, the shell-breaking hammer head 4 is output under the drive of the shell-breaking cylinder 1. The shell-breaking hammer head 4 extends out of the decapsulation device 6 and breaks through the shell surface to immerse electrolyte. After the shell breaking is in place, the shell-breaking cylinder 1 drives the shell-breaking hammer head 4 to retract. When retracting, the electrolyte adhering to the shell-breaking hammer head 4 is scraped clean by the decapsulation device 6. After the cutting edge 7 is blunted or a large amount of electrolyte is solidified on the outer surface of the decapsulation device 6, the device is clamped in the mounting groove 8 with an installation wrench, the decapsulation device 6 is twisted and removed and replaced.
