[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
See Fig. 1 to Fig. 3, a kind of electrolyzer anode rod tightness system, comprising: cover the horizontal cover plate 1 be located on electrolyzer, horizontal cover plate 1 is provided with the first guide rod hole 11 run through on it; Electrolyzer anode rod tightness system also comprises: be covered on the base plate 2 on horizontal cover plate 1, be arranged on base plate 2 from open-and-close mechanism 3, be fixedly installed on horizontal cover plate 1 for limit base plate 2 move position-limit mechanism 4; Comprise from open-and-close mechanism 3 and to be positioned at above base plate 2 and the movable push 31 be positioned on front side of the first guide rod hole 11, to lay respectively on base plate 2 and to be positioned at two push pedal unit 32 of the first guide rod hole 11 left and right side, and by gear unit 33 that two push pedal unit 32 are fixedly connected with movable push 31 two ends respectively; Base plate 2 has second guide rod hole 21, first guide rod hole 11 corresponding with the first guide rod hole 11 and the second guide rod hole 21 to align and arrange; Push pedal unit 32 comprises the waling stripe 321 be fixedly installed on gear unit 33, the vertical links 322 be fixedly connected with waling stripe 321, is articulated with the hinged-support 323 of the intersection of waling stripe 321 and vertical links 322; Hinged-support 323 fixedly mounts on a base plate 2; Position-limit mechanism 4 comprises the upper limit plate being fixedly installed on base plate 2 front portion, and is fixedly installed on the side limiting plate of base plate 2 left and right side; Electrolyzer anode rod tightness system also comprises sealing mechanism 5, and sealing mechanism 5 comprises three sealing units being fixedly installed in movable push 31 and being fixedly installed in respectively on vertical links 322; Wherein, the elastic element for pulling vertical links 322 to rotate around hinged-support 323 being separately positioned on guide rod 6 arranged on left and right sides is also comprised from open-and-close mechanism 3, elastic element is extension spring 34, and extension spring 34 one end is connected with base plate 2, and the other end is connected with the intermediate point of the long axis direction of vertical links 322.
Gear unit 33 comprises the slipway 331 with slideway being fixedly installed in two ends on the downside of movable push 31 respectively, and is arranged in the slide block 332 in slideway, and waling stripe 321 is fixedly installed on slide block 332.
When anode changes to, first anode rod 6 contacts with sealing mechanism 5, compression seal mechanism 5, when sealing mechanism 5 is compressed to a certain degree, power is delivered in movable push 31, movable push 31 is moved to the direction away from anode rod 6, movable push 31 drives the slipway 331 on left side and right side to move, slide block 332 pursuit movement in slipway 331, waling stripe 321 and vertical links 322 is driven to rotate around hinged-support 323 when slide block 332 moves, vertical links 322 drives the sealing mechanism 5 be installed on it to compress anode rod 6, thus realize press seal, when vertical links 322 rotates, coupled extension spring 34 is strained.
When certain side is partial in the installation site of anode, anode rod 6 can first contact with the sealing mechanism 5 of that side of deflection.Because base plate 2 is what to rely on electrolyzer magnetic-adsorption on horizontal cover plate 1, that installs along with anode rod 6 gos deep into, that side first contacted is subject to thrust can be increasing, when thrust is greater than the adsorptive power of electrolyzer to base plate 2, that side that base plate 2 meeting anode guide rod 6 is partial to is moved, and the distance of movement just in time equals the distance that anode rod 6 departs from central position, thus seal after realizing centering.
When anode swaps out, anode rod 6 is extracted out from horizontal cover plate 1 opening part, the extension spring be tightened up is discharged, thus pull vertical links 322 to rotate, vertical links 322 drives the sealing mechanism 5 be installed on it to open to the direction of horizontal cover plate 1 opening, thus realizes the expansion action of anode rod 6 tightness system.
It should be noted that, the utility model application mention front side, left side, right side all to scheme front side in (the one-piece construction schematic top plan view of the utility model anode rod 6 tightness system), left side, right side be as the criterion.
Compared with correlation technique, elastic element in open-and-close mechanism is placed in respectively on described vertical links, the effect of self-centering can not only be retained, and the setting of elastic element position avoids and interferes with positive bar, but be arranged on anode rod side, greatly reduce this device and safeguard and consumable accessory replacing difficulty.And elastic element is extension spring, stage clip does not need liner, also just decreases a component, reduces cost of manufacture.
Above-described is only embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection domain of the present utility model.
