Abstract
The invention discloses a dry type water-free flue valve of a hot-blast stove, which comprises an inclined plate and a two-connecting rod, wherein one end of the inclined plate is hinged with a rotary shaft; one end of the two-connecting rod is hinged on the inclined plate, and the other end of the two-connecting rod is hinged on a hydraulic power rotary shaft; the transmission of the two-connecting rod is realized through a hydraulic start device; the start device is arranged on the hydraulic power rotary shaft. In the dry type water-free flue valve disclosed by the invention, an expected heat insulation effect is achieved by adding a heat insulation refractory material layer on the inclined plate, the steel pipe structure and action of the two-connecting rod drive the lifting of the inclined plate to control the opening/closing of the valve, and the weight of the equipment is remarkably reduced; water is not required in the using process of the valve, thus the water resources are saved, the valve is relatively convenient to overhaul, and the production cost of an enterprise is reduced.
Description
Technical field
The invention belongs to blast funnace hot blast stove technical field, be specifically related to the anhydrous flue valve of hot air oven of a kind of dry type.
Technical background
Hotblast stove is the crucial support equipment of blast furnace, operation quality and the productive capacity quality of blast furnace of hotblast stove have substantial connection, chimney valve is a key equipment of hotblast stove, mainly to control to cut off flowing of flue heat air, chimney valve is worked under high temperature variable change mal-condition, crucial by-pass valve control equipment, the chimney valve using is at present mainly hot blast valve, the volume of hot blast valve is large, weight large, complex structure, must water flowing, operating switch difficulty, amount of machining is large, cost value is very high, easily occur fouling, and maintenance lifting is difficult.
Summary of the invention
For problems such as the necessary water flowing of hot blast valve in prior art, operating switch difficulty, maintenance lifting difficulties, the invention provides the anhydrous flue valve of hot air oven of a kind of dry type, the heat-insulating method of this chimney valve employing spraying inside and outside refractory materials, can be high temperature resistant.
Object of the present invention is achieved through the following technical solutions: the anhydrous flue valve of hot air oven of a kind of dry type, comprise swash plate and two connecting rods, one end and the rotating shaft of swash plate are hinged, one end of two connecting rods is hinged on swash plate, the other end of two connecting rods is hinged on hydraulic power rotating shaft, the transmission of two connecting rods is by fluid pressure type starter gear, and starter gear is arranged on hydraulic power rotating shaft.
Described swash plate inner side is provided with refractory masses.
Described swash plate inner side also arranges soft seal, and soft seal is positioned at the outside of refractory masses.
The area of described swash plate is greater than the cross-sectional area of floss hole.
Two described connecting rods are for to consist of two hinged pipe steel.
Beneficial effect: the present invention reaches the effect of heat insulation of expection by increase insulating refractory layer on swash plate, the steel-tube construction of two connecting rods and action drive the lifting of swash plate to carry out the switch of by-pass valve control, significantly alleviate reduction weight of equipment, the operation of valve switch hydraulic starting is very simple, alleviate hand labor intensity, in the use procedure of this valve without water flowing, saving water resource, overhaul more conveniently, reduced the production cost of enterprise.

Fig. 2 is the structural representation of the present invention while opening;
Fig. 3 is plane external structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the anhydrous flue valve of hot air oven of a kind of dry type, comprise swash plate 1 and two connecting rods 3, one end of swash plate 1 and rotating shaft 2 are hinged, one end of two connecting rods 3 is hinged on swash plate 1, the other end of two connecting rods 3 is hinged on hydraulic power rotating shaft 6, and the transmission of two connecting rods 3 is by fluid pressure type starter gear 7, and starter gear 7 is arranged on hydraulic power rotating shaft 6.Swash plate 1 inner side is provided with refractory masses 4.Swash plate 1 inner side also arranges soft seal 5, and soft seal 5 is positioned at the outside of refractory masses 4.The area of swash plate 1 is greater than the cross-sectional area of floss hole.Two connecting rods 1 are for to consist of two hinged pipe steel.
Working process is as follows: when hot blast stove burning, fluid pressure type starter gear 7 is opened, and drives two connecting rods 3 to shrink, and swash plate 1 is lifted, and now chimney valve is opened, and chimney is taken high-temperature flue gas gas away by flue.When hotblast stove vault temperature of combustion is generally to 1300 about degree or when above, large blast furnace is about 1400 degree, and burning stops, now, starter gear 7 cuts out, and two connecting rods 3 are upheld, and swash plate 1 is put down, close chimney valve, prepare to blow in blast furnace, so periodically circulate.
