The specific embodiment
Be described in further detail below in conjunction with the structure and the operation principle of accompanying drawing formation nickel regenerated resources alloy melting stove bell provided by the utility model:
Be the cross-sectional view of formation nickel regenerated resources alloy melting stove bell provided by the utility model as depicted in figs. 1 and 2.Promptly the structure of this bell is made of side ring 1 and ball crown type caping 2, this side ring and ball crown type caping are that upper and lower double layer of metal wall 11,12 constitutes the jacket structure for water that is communicated with, the side ring water jacket that constitutes water jacket is provided with three water inlets arranged side by side 3,4 and 5 that are communicated with the water source, is provided with first, second and the 3rd totally three water distributors 6,7 and 8 that are communicated with three water inlet pipes couplings respectively in water jacket; Be set with three electrode holes 20 and the batching hole 21 that are used to insert electrode in the ball crown type caping centre that constitutes water jacket; The centre of metallic walls 11 is provided with apopore 23 on the ball crown type caping that constitutes water jacket.
During use bell is covered on body of heater, make the current influent stream in the water jacket go out, thereby reach the purpose that makes the bell cooling by water inlet and delivery port.
In order to make that flowing to water in the water jacket can make the bell uniform decrease in temperature, middle water inlet and ball crown type caping circle center line connecting are divided into ball crown type caping water jacket left and rightly partly distinguishes 9,10, the first and the 3rd water distributor 6 and 8 that wherein is in left and right half district respectively is arranged at left and right half district of ball crown type caping water jacket respectively, and first water distributor 6 extend into 1/2nd places of semicircle water jacket of living in along the arc limit of side ring, another water distributor extend into 3/4ths places of water jacket of living in along the arc limit of described side ring.So just can be so that be in the water circulation that first water distributor 6 of left half-court can satisfy the water jacket left half-court, the 3rd water distributor 8 that is in the right half-court can satisfy the upper water circulation of water jacket right half-court, second water distributor 7 that is in the bottom can satisfy the water jacket part left and right water circulation partly distinguished approaching with this filling pipe, thereby reach the even circulation cooling of water in the water jacket, and prolong the service life of bell.
