Description
Technical field
The present invention relates to a kind of wear-resisting nothing and leak the sintering machine unloading valve, belong to technical field of sealing technology.Be mainly used in the sintering machine wind box bottom unloading valve of metallurgy industry.
Background technique
The unloading valve of the sintering machine wind box of metallurgy industry bottom will bear the negative pressure that the sintering machine exhausting produces, and the wearing and tearing of the solid block sintering deposit that drops of sintering pallet, thereby causes wearing and tearing to leak out, thereby influences SINTERING PRODUCTION efficient and energy consumption.At present, this unloading valve mainly contains push-pull valve, taper, dish-shaped Flap valve etc., and envelope gas, sealing body material all are same sealing surfaces.The applicant's right formerly " a kind of gas-solid does not have the leakage material discharging " (ZL201110182040.9) has realized that gas, solid material different sealing face sealing and solid material can not be stuck in the problem on the sealing surface.But the solid sintering deposit wearing and tearing wall that also exists sintering pallet to drop causes the phenomenon of leaking out.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of wear-resisting nothing to leak the sintering machine unloading valve, put forth effort to solve the feed inlet and outlet and the valve plate wear problem that frequently contact with slag charge, further improve the magnetic seal structure simultaneously, make it reliable and durable more.
Technological scheme of the present invention is achieved in that this wear-resisting nothing leakage sintering machine unloading valve, comprises that the top is provided with material feeding mouth and the below arranges the grey casing of unloading of discharge port, and the material feeding mouth bottom arranges the arc valve plate that is hinged on the cursor; The material feeding mouth bottom arranges the frustoconic shape magnetic seal, absorption magnetic seal medium in the round table surface, and the valve plate outer upper end is provided with round table-like magnet case for to cooperate with the frustoconic shape magnetic seal with the magnetic seal surface of contact; The material feeding mouth inwall, discharge port inwall, arc valve plate inwall and unload grey casing inwall and be provided with wear-resisting artificial stone layer.
Described wear-resisting nothing is leaked the material feeding mouth inwall of sintering machine unloading valve, the discharge port inwall, and arc valve plate inwall and unload grey casing inwall groove, grid or bar rib all are set is so that be combined with wear-resisting artificial stone layer.
The wear-resisting artificial stone layer that described wear-resisting nothing is leaked the sintering machine unloading valve is formed by ceramic particle and hydrated cementitious gelling, and the mass ratio of ceramic particle and cement is between 9:1～5:5.
The ceramic particle that described wear-resisting nothing is leaked the wear-resisting artificial stone layer of sintering machine unloading valve obtains by discarded ceramic products is broken, and granularity is 0.1mm～15mm.
Wear-resisting nothing of the present invention is leaked the sintering machine unloading valve, and solid material can not be stuck on any sealing surface, thereby can realize gas, all do not have a leakage admittedly.And the position that contacts with blanking such as shutting off valve, receiving opening, discharge port and casing constitutes by amorphous wear-resisting artificial stone layer, can avoid the blanking mill to leak and leaks out.
The present invention is convenient to processing with formerly the right structure compared is simpler, and easy to maintenance, exploitativeness is strong.Sintering machine adopts the present invention can reduce air leak rate of air curtain significantly, energy-saving and cost-reducing obvious effect of increasing production.

Embodiment
As Fig. 1, the wear-resisting nothing of the present invention shown in Figure 2 is leaked the sintering machine unloading valve, comprises that the top is provided with material feeding mouth 3 and the below arranges the grey casing 5 of unloading of discharge port 4, and the material feeding mouth bottom arranges the arc valve plate 2 that is hinged on the cursor 8; The material feeding mouth bottom arranges frustoconic shape magnetic seal 1, absorption magnetic seal medium in the round table surface, and the valve plate outer upper end is provided with round table-like magnet case with the magnetic seal surface of contact and cooperates with frustoconic shape magnetic seal 1; The material feeding mouth inwall, discharge port inwall, arc valve plate inwall and unload grey casing inwall and be provided with wear-resisting artificial stone layer.
The magnetic field sealing medium of the right formerly " a kind of magnetic field method for sealing of air gap " that described magnetic seal medium adopts the applicant in (ZL200710061449.9), magnetic seal is that permeability magnetic material or permanent-magnet material are made, and is not giving unnecessary details at this.
Described material feeding mouth inwall, the discharge port inwall, arc valve plate inwall and unload grey casing inwall groove, grid or bar rib all are set is so that be combined with wear-resisting artificial stone layer.
Described wear-resisting artificial stone layer is formed by ceramic particle and hydrated cementitious gelling, and the mass ratio of ceramic particle and cement is between 9:1～5:5.Ceramic particle obtains by discarded ceramic products is broken, and granularity is 0.1mm～15mm.
During work, by driving mechanism cursor 8 is rotated, drive arc valve plate 2 by opening state to closed condition, as Fig. 1.In valve plate closed closed procedure, arc valve plate 2 had blocked the solid sintering deposit materials flow that the sintering pallet that constantly fallen by material feeding mouth 3 drops, and the solid sintering deposit that drops accumulates arc 2 bottoms.Meanwhile, valve plate 2 outer circle table tops suitable for reading enter in the frustoconic shape magnetic seal 1, have sealed air flue, have reached the purpose of envelope gas.
The wear-resisting artificial stone layer of valve plate 2 upper surfaces contacts with material feeding mouth 3 ends, has sealed the materials flow of solid sintering deposit, is not is not worn and torn by the solid sintering deposit again simultaneously, the purpose that has reached sealing body material and do not leaked out by the leakage of blanking mill.
The technological scheme that above-mentioned magnetic seal arranges no longer describes in detail at another open in (ZL201110182040.9) of right " a kind of gas-solid does not have the leakage material discharging " formerly of the applicant.
Shown in Figure 2 in arc valve plate 2 opening processes, leave material feeding mouth 3 after, the materials flow of solid sintering deposit enters into by material feeding mouth 3 and unloads grey casing 5, and flows out through discharge port 4.Above-mentioned parts and blanking contact position are provided with wear-resisting artificial stone layer, and its hardness is higher than the hardness of blanking, thereby can not be worn.Reached the purpose that discharging is not worn again.
Because arc valve plate 2 and frustoconic shape magnetic seal 1 among the present invention are solid of rotation, so the easier assurance of machining accuracy.
Wear-resisting artificial stone layer among the present invention, mainly the ceramic particle that is broken into by discarded ceramic products is formed.Therefore, enforcement of the present invention will consume the waste ceramic that is difficult to spontaneous decomposition, not only turn waste into wealth but also environmental protection.
