Abstract

The utility model belongs to a crust breaking device used on an aluminum electrolytic cell in non-ferrous metal smelting equipment, particularly a wear-resistant alloy crust breaking hammer used on an aluminum electrolytic cell, the crust breaking hammer comprises a hammer stem (1) and a hammer head (3), wherein a hammer handle (2) is connected into the lower end of the hammer stem (1); a welding bevel (2-1) is formed at the joint of the hammer handle (2) and the hammer stem (1); the hammer handle (2) and the hammer stem (1) are fixed together on the welding bevel (2-1) by electric welding process; a hammer core (4) with a circle arc-shaped lower end is arranged below the hammer handle (2); the hammer handle (2) and the hammer core (4) are integrated into a whole; a plurality of reinforcing ribs (4-1) are arranged on the outer circumference of the hammer core (4) below the hammer handle (2); two ring-shaped anti-falling grooves (4-2) are formed on the outer circumference of the middle part of the hammer core (4); and the pestle-shaped hammer head (3) is cast-molded on the outer circumference of the hammer core (4). In the wear-resistant alloy crust breaking hammer used for the aluminum electrolytic cell, the hammer stem and the hammer handle are connected more tightly, so that the service life of the crust breaking hammer is increased by more than three times, thereby saving cost.

Description

Aluminum electrolyzing cell used wear resistant alloy crust breaking hammer

Technical field

The utility model belongs to the crust breaker of using on the aluminium cell in the non-ferrous metal metallurgy equipment, particularly a kind of aluminum electrolyzing cell used wear resistant alloy crust breaking hammer.

Background technology

At present, surplus the used electrolyzer nearly 20,000 of domestic aluminum electrolysis industry, and the crust breaking hammer that uses on the groove have 100,000 approximately surplus, what adopt now substantially all is to form with smooth bar processing and low-carbon cast steel casting, and in the high temperature of electrolytic aluminum groove more than 950 ℃, have only about three months general work-ing life, and the quality to aluminium liquid has a significant impact after the crust breaking hammer thawing, frequent maintenance and replacing to crust breaking hammer also increase working strength of workers, and the waste fund is produced in influence simultaneously.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of cheap, long service life, the simple aluminum electrolyzing cell used wear resistant alloy crust breaking hammer of replacing weldprocedure.

The technical scheme that the utility model technical solution problem adopts is: aluminum electrolyzing cell used wear resistant alloy crust breaking hammer comprises hammer stem, tup body, be characterized in the hammer stem lower end, connecting a hammer handle, hammer handle and hammer stem junction are provided with bevel for welding, with electric welding that hammer handle is fixing with hammer stem on bevel for welding, being provided with the lower end below hammer handle is the hammer core of circular arc, hammer handle is an one with the hammer core, outer periphery multiple tracks stiffening web on the hammer core below the hammer handle, place's outer periphery twice annular anti-avulsion groove in the middle of the hammer core is at the peripheral casting of hammer core pestle shape tup body.

The beneficial effects of the utility model are: aluminum electrolyzing cell used wear resistant alloy crust breaking hammer is owing to be provided with bevel for welding on hammer handle, it is more firm that hammer stem is connected with hammer handle, adopt twice casting technique and annular anti-avulsion groove, wear resistant alloy and soft steel are cast as one, crust breaking hammer is increased more than three times work-ing life, reduce maintenance and change number of times, saved fund.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is aluminum electrolyzing cell used wear resistant alloy crust breaking hammer structure iron.

Among the figure, the 1-hammer stem; 1-1-welding rod line; The 2-hammer handle; The 2-1-bevel for welding; 3-tup body; 4-hammers core into shape; The 4-1-stiffening web; 4-2-annular anti-avulsion groove;

Embodiment

Embodiment, with reference to accompanying drawing 1, be provided with bevel for welding 2-1 with hammer stem 1 junction on the hammer handle 2 of aluminum electrolyzing cell used wear resistant alloy crust breaking hammer, on the inclined-plane of bevel for welding 2-1, hammer handle 2 and hammer stem 1 are fixed together with welding rod line 1-1, being provided with lower end below hammer handle 2 is the hammer core 4 of circular arc, and hammer handle 2 is an one with hammer core 4.Hammer core 4 outer periphery four road stiffening web 4-1 below hammer handle 2, the place establishes twice annular anti-avulsion groove 4-2 in the middle of hammer core 4.At hammer core 4 peripheral casting pestle shape tup bodies 3.Its manufacture method is the hammer handle and the

hammer core

2,4 of casting soft steel earlier, then at the tup body 3 of hammering core 4 external application vacuum casting methods casting wear resistant alloy into shape, again the upper end of hammer handle 2 is inserted in hammer stem 1 endoporus, with electric welding that hammer handle 2 is fixing with hammer stem 1 welding, owing to have stiffening web 4-1 and annular anti-avulsion groove 4-2 on the hammer core 4, make hammer core 4 combine more firm with tup body 3.

Claims

1. aluminum electrolyzing cell used wear resistant alloy crust breaking hammer, comprise hammer stem (1), tup body (3), it is characterized in that in hammer stem (1) lower end, connecting a hammer handle (2), hammer handle (2) is provided with bevel for welding (2-1) with hammer stem (1) junction, go up with electric welding hammer handle (2) is fixing with hammer stem (1) at bevel for welding (2-1), be provided with the hammer core (4) that the lower end is a circular arc in hammer handle (2) below, hammer handle (2) is an one with hammer core (4), hammer core (4) in hammer handle (2) below is gone up outer periphery multiple tracks stiffening web (4-1), place's outer periphery twice annular anti-avulsion groove (4-2) in the middle of hammer core (4) is at the peripheral casting of hammer core (4) pestle shape tup body (3).
