Abstract
The utility model discloses a cleaning-free self-locking-type steel claw protection ring which comprises two semi-circular ring bodies; one ends of the ring bodies are provided with projections; the other ends of the ring bodies are provided with grooves; and the projections and the grooves are clamped mutually. According to the utility model, two ends of the ring bodies are respectively provided with the projections and the grooves which are clamped mutually; when in use, the two ring bodies are used in pairs; and the projections and the grooves are clamped on the crossed interface of the two ring bodies. The cleaning-free self-locking-type steel claw protection ring is not required to be bound, and labor capacity can be reduced.
Description
Technical field
The utility model relates to a kind of alumina producing equipment, is specifically related to a kind of steel pawl safety guard.
Background technology
Electrolytic aluminum need to go out aluminium liquid as anode electrolysis with the charcoal piece, when the charcoal piece is placed, becomes one by the phosphorus pig iron casting with the anode rod group, forms qualified anode group.When the anode carbon block that casting is good uses to potroom, need with the crawl of steel pawl.Because working temperature is about 800 ° during the crawl of steel pawl, the high temperature meeting steel pawl phenomenon namely occurs rinsing so that the steel pawl occurs melting phenomenon.For preventing the phenomenon of rinsing the steel pawl, need to will cast with guard ring highly is about 60mm steel pawl leg and protects more than the plane.The guard ring that uses both at home and abroad at present is semicircle, and then 2 guard rings are used the guard ring binding just in time with 1 steel pawl leg parcel, could effectively protect the steel pawl like this.Have aborning following problem: bundle protection ring needs special personnel operate, and the labour intensity of workman's bundle protection ring is very large, and working efficiency is lower.The steel pawl of using take the 400KA electrolyzer is as example; its steel pawl all is 8 pawls, and this just means each new utmost point needs 8 collateral retaining ring, and the new anode carbon block quantity that use every day reaches 234 groups maximum the time; need altogether bundle protection ring 1872 pair/skies, annual bundle protection ring is 660,000 pairs approximately.This has just caused very large workload.
The utility model content
Labor capacity was excessive when the technical problems to be solved in the utility model was steel pawl colligation guard ring, and what provide a kind of and can not need colligation, reduce to use in the alumina producing of labor capacity exempts to clear up the self-locking steel claw protection ring.
The technical solution of the utility model realizes in the following manner: a kind ofly exempt to clear up the self-locking steel claw protection ring, comprise two semicircular ring bodies, described ring body one end is provided with projection, and an end is provided with groove, and projection and groove engage mutually.
The end face of described projection, groove is S-type.
The end face of described projection, groove is step-like.
In the utility model, the two ends of ring body are respectively equipped with projection and the groove of mutual engaging, and in the time of use, two ring bodies use in pairs, at the interface that two ring bodies intersect, and projection and groove engaging.Do not need colligation, can reduce labor capacity.

Embodiment
Embodiment 1: as depicted in figs. 1 and 2, the present embodiment comprises two semicircular ring bodies 1, and described ring body 1 one ends are provided with projection 2, one ends and are provided with groove 3, and projection 2 and groove 3 engage mutually.Described end face protruding 2, groove 3 is S-type.When two ring bodies 1 are used in conjunction with, be similar to the shape of the Diagram of the Supreme Ultimate, cooperation by projection 2 and groove 3, realized the each other self-locking of two ring bodies, install so more convenient, do not re-use metallic substance and bundle, assembling speed can realize by 30 original pairs/hour bring up to, 70 pairs/hour, increase work efficiency.And can reduce the binding workman, economize on the use of funds.In the utility model, the outside diameter of ring body is that 290mm, interior diameter 166mm, high 60 ± 2mm, weight are 6.2 ± 0.3kg.
Embodiment 2: as shown in Figure 3 and Figure 4, the present embodiment comprises two semicircular ring bodies 1, and described ring body 1 one ends are provided with projection 2, one ends and are provided with groove 3, and projection 2 and groove 3 engage mutually.Described end face protruding 2, groove 3 is S-type.Described end face protruding 2, groove 3 is step-like.
Except the end surface shape of embodiment 1 and 2 described projections and groove, in the utility model, the projection and groove can also be other can block and shape.
Claims (3)
1. exempt to clear up the self-locking steel claw protection ring for one kind, comprise two semicircular ring bodies (1), it is characterized in that: described ring body (1) one end is provided with projection (2), and an end is provided with groove (3), and projection (2) and groove (3) be engaging mutually.
2. according to claim 1ly exempt to clear up the self-locking steel claw protection ring, it is characterized in that: the end face of described projection (2), groove (3) is S-type.
3. according to claim 1ly exempt to clear up the self-locking steel claw protection ring, it is characterized in that: the end face of described projection (2), groove (3) is step-like.
