Description
Technical field
The utility model belongs to aluminium smelting technology field, is a kind of high-temperature flue valve specifically.
Background technique
Now heavily melt for aluminium scrap in the industry and reclaim based on reverberating furnace, although reverberating furnace has lot of advantages, but it is always very low in energy utilization rate, utilize common high speed or burner with inferior speed fuel availability be no more than 35%, a large amount of heat energy to be escaped loss by flue gas.Reach capacity owing to being utilized by self heat absorption mode of smelting furnace aluminium material, by becoming the first-selection reducing molten aluminium energy consumption to the flue gas utilization of escaping.
High temperature smoke pipe adopts volute to make, and lined ceramics tapetum fibrosum and insulated pouring material, high temperature smoke pipe valve is a kind of device be arranged on high temperature smoke pipe, for regulating exhaust gas volumn, and high-temperature flue gas is drained into dust-removing flue.The defect of current this universal device is, between flashboard and flue wall, gap is large, seals bad; Valve body and valve plate are all made by metal, easily stuck because expanding during high temperature; Cost is high; These are all the current problem demanding prompt solutions of the art.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of high-temperature flue valve.Through the checking of embodiment, achieve the combination of mechanical transmission and pneumatics, its sealing structure is reliable, and simple and practical cost is low, easy-to-operate.
The utility model is achieved by the following technical solution, and a kind of high-temperature flue valve, comprises valve body, pouring material, filler seat, valve plate, valve rod, graphite packing, fixed cover, and cylinder, cranks arm, joint, fixed base.
Castable is located at valve interior wall, establishes fixed cover outside graphite packing.Fixed cover plays the effect compressing graphite packing.
Described valve plate and valve rod are connected as a single entity, and valve plate is the concentric plectane more smaller than valve block internal diameter, and side is provided with one gusset, prevents high temperature deformation.Valve rod is metal hollow pipe, and stretches out from fixed cover, and the end of exposing valve body is provided with one section of nipple, to facilitate external pipeline.
Built insulation pouring material in described valve body, valve body is metal; Valve body arranges filler seat, press-in graphite packing in filler seat, and compress with fixed cover; Described valve body arranges fixed base, fixed base arranges joint, to connect cylinder, cylinder other end is connected with cranking arm; Crank arm and to be connected with valve rod.
Described pouring material is cast-in-place structural, and inner face is circular and valve plate sealing.
Described cylinder is oscillating cylinder, when cylinder arm stretches, drives rotation of cranking arm, thus the rotation of band ovable valve stem and valve plate, realize the keying of valve.
The beneficial effects of the utility model are:
1, while discharging high-temperature flue gas, Cryogenic air is around mixed into by injection principle, the safety of protection deduster.
2, adopt the valve plate of nonmetallic pouring material and metal respectively, gap can be accomplished very little, is not easy stuck during high temperature, and adopts graphite packing to tamp, and sealing is reliable.
3, adopt cylinder and fixed base, structure is simply convenient to maintain and replace, and cost is low.
Accompanying drawing explanation
Fig. 1 is mechanical construction drawing of the present utility model;
Fig. 2 is the radial cross-section that filler seat is put.
In figure: 1, valve body; 2, pouring material; 3, filler seat; 4, valve plate; 5, valve rod; 6, graphite packing; 7, fixed cover; 8, cylinder; 9, crank arm; 10, joint; 11, fixed base.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model provides a kind of specific embodiment of high-temperature flue valve, includes valve body 1 in this embodiment, pouring material 2, filler seat 3, valve plate 4, valve rod 5, graphite packing 6, fixed cover 7, and cylinder 8 cranks arm 9, joint 10, fixed base 11.
Valve body 1 described in the present embodiment is metal, and this enforcement adopts 5mm general steel plate.Valve body 1 is the cylindrical body that one section, centre rolls into diameter 400mm, left and right is supporting arranges two circular Steel Plate Flanges, the thick insulation pouring material 2 of 50mm has been built in inside, pouring material 2 internal diameter is that 300mm is circular, in the middle of valve body 1, diameter 100mm filler seat 3 is set, press-in 5 circle graphite packing 6 in filler seat, and compress with fixed cover 7.
Described valve plate 4 and valve rod 5 are welded as a whole, and valve plate 4 is slightly less than the stainless steel plectane of 400mm for diameter, and side is welded with gusset vertical with valve rod together, to prevent valve plate 4 temperature distortion when high temperature.Valve rod 5 is the stainless steel hollow tube of external diameter 57 ~ 73mm, 65mm in the present embodiment; And stretch out in fixed cover 7, the end of exposing valve body 1 is provided with the long nipple of one section of 2 cun of size 80mm, to facilitate external pipeline.
Described valve body 1 welds 5 bugle steel fixed bases 11, length 350mm; Fixed base is arranged joint 10, to connect cylinder 8;
Described cylinder 8 diameter 50mm, stroke 175mm; One, cylinder is connected with the joint 10 on fixed base 11, and other end 9 to be connected with cranking arm; Crank arm and 9 to be fixedly connected with valve rod 5, realize synchronous rotary.
Described pouring material 2 is located at valve interior wall, and is cast-in-place structural, concentric with valve plate 4 when internal diameter is circle and assembles.
Described cylinder 8 is oscillating cylinder, when cylinder arm stretches, drive is cranked arm rotation, thus the rotation of band ovable valve stem 5 and valve plate 4, the unlatching of valve plate 4 is realized when cylinder suction, realize the closedown of valve plate 4 during exhaust, a stroke of cylinder 8 realizes valve and circulates to of closing (valve plate 4 is vertical with valve body 1 direction) completely from opening (valve plate 4 is consistent with valve body 1 direction) completely.
