Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis, in particular to a shell-breaking hammer head for aluminum electrolytic cells. Background Art

[0002] In the process of electrolytic aluminum production, a large number of shelling hammers are consumed due to the wear of the alloy head of the shelling hammer, the deformation of the hammer rod, the explosion of the hammer head, etc. In order to meet the normal operation of the electrolytic cell, a new shelling hammer head needs to be made. The existing process is to connect the shelling hammer rod and the alloy hammer head by welding, but when the shelling hammer head is processed and manufactured by this method, there are the following disadvantages:

[0003] (1) When a single shell hammer head is partially damaged, the shell hammer head needs to be disassembled as a whole and handed over to the processing personnel for secondary processing, which wastes manpower;

[0004] (2) During the welding process of the shell hammer head, some defective products will be produced due to welding, measurement and other reasons and cannot be put into normal use, resulting in secondary waste of materials;

[0005] (3) Due to the limited installation space, the weld height is limited, which can easily cause weld cracking and hammer head falling, thus affecting the original aluminum and iron content. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The technical problem to be solved by the utility model is that the shell beating hammer head needs to be disassembled as a whole after being partially damaged, which wastes manpower and material resources, and the shell beating hammer head is easy to fall off during use.

[0008] (II) Technical solution

[0009] In order to solve the above technical problems, the technical solution provided by the utility model is: a shelling hammer head for aluminum electrolytic cells, comprising a wear-resistant alloy hammer head and a hammer rod connected to the wear-resistant alloy hammer head, one end of the wear-resistant alloy hammer head is provided with a stud, and one end of the hammer rod is provided with a screw barrel threadedly connected to the stud.

[0010] As an improvement, the stud and the screw barrel are both provided with positioning holes that cooperate with each other, and a pin is provided in the positioning hole.

[0011] As an improvement, the wear-resistant alloy hammer head and the hammer rod are both provided with a disassembly plane, the disassembly plane is arranged close to the stud, and the disassembly plane is arranged close to the screw barrel.

[0012] As an improvement, a pull ring is provided at one end of the hammer rod away from the screw barrel.

[0013] (III) Beneficial effects

[0014] The advantages of the utility model compared with the prior art are:

[0015] 1. Design connection threads and positioning holes at the connection position between the hammer rod and the wear-resistant alloy hammer head. Use this quick and easy disassembly connection method to connect the hammer rod and the alloy hammer head, which is simple and easy to operate;

[0016] 2. On-site maintenance personnel do not need to carry the hammer rod to the processing workshop for secondary cutting, measurement and welding. They can be installed on site immediately after disassembly, achieving fast operation.

[0017] 3. Pre-set positioning holes at specific positions of the hammer rod and the wear-resistant alloy hammer head can prevent the hammer rod and the wear-resistant alloy hammer head from moving after threaded connection, and at the same time play a fixing role, making the connection and trial more reliable;

[0018] 4. In order to facilitate disassembly and installation, the connecting threads on the hammer rod and the wear-resistant alloy hammer head are all processed into T-type threads, and a part of the gap is reserved for matching. When the hammer head expands due to heat and contracts due to cooling, the gap can be used as an expansion gap to avoid the hammer rod from bursting or the wear-resistant alloy hammer head and pin shaft from being damaged.
