Description

Equal pressure Double-deck cinder discharge valve

Technical field

The utility model is related to metallurgical, field of Environment Protection, is particularly suitable for use in sintering large flue, central cooler, electric precipitation, cloth bag and removes There is larger positive and negative pressure in the ash silos such as dirt device puts grey industry, specifically a kind of as the sealing dust exhausting equipment of ash collecting box Equal pressure Double-deck cinder discharge valve.

Background technology

The Double-deck cinder discharge valve and other unloading valves that current sintering machine large flue ash silo, Environmental-protecting dust-removing device ash silo are used have one Individual common shortcoming, exactly occurs the phenomenon of putty, hanging during use, causes to put grey difficulty, and it is long to put the grey time, The reason for this phenomenon occur not exclusively is that valve body leaks out and caused, do not leaked out even if unloading valve putty equally also occurs, it is outstanding The phenomenon of material, because above Double-deck cinder discharge valve in ash silo being higher negative pressure, up to more than 10 kPas had, and stored up in the middle part of valve body It is an atmospheric pressure in dirt storehouse, when valve is opened on the upside of Double-deck cinder discharge valve, the air in dust storehouse will be ceaselessly to upstream It is dynamic, untill air pressure is equal with ash silo negative pressure, and when the material of upside ash silo is influenceed to flow up compared with multi-space gas by resistance Time it is longer, the hanging time is also just long, time of the resistance compared with small flow of air flows upwards when the material in ash silo is less Just shorter, the time of hanging is also just short, and the time that the upper lower valve plate of Double-deck cinder discharge valve is opened is of short duration and is fixed, thus Cause material in storehouse to keep the state suspended, due to the degree difference of suspension occur expecting in storehouse it is more few it is better put be more difficult to put, Negative pressure is more low better to put the higher phenomenon for being more difficult to put, it is necessary to which the frequency for putting ash using increase keeps low material position or reduction negative pressure to delay Solve this problem.Simultaneously because air-flow is flowed up by negative pressure and material by gravity is wanted slide downward, there is local material and do not stop Play up and down cause the particle in material to the erosive wear of Double-deck cinder discharge valve seal, valve body and ash silo, because hanging is existing The presence of elephant, which is extended, puts time of ash and adds the frequency for putting ash, also increases air and is caused into the quantity of ash silo to life The influence of production, while adding the workload of post operation, the abrasion for also increasing unloading valve and ash silo increases repair and maintenance Expense.

The content of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art to unload ash there is provided equal pressure bilayer Valve, the utility model, which solves the technical scheme that its technical problem used, is：Structure of the present utility model is bypassed back including upper strata By flow tube, expansion joint, reflux tube valve, upper strata by-passing valve lip, upper strata bypass valve plate sealing gasket, upper strata bypass valve plate, upper strata By port valve bar spring, upper strata bypass valve plate support, lower floor's bypass pipe, lower floor's by-passing valve lip, lower floor's bypass valve plate sealing gasket, lower floor Port valve plate, lower floor's bypass valve rod spring, lower floor's bypass valve plate support, upper valve plate, unloading valve body, lower valve plate, upper valve shaft, lower valve Board shaft, it is characterised in that lead at the top of the bypass return line of upper strata in the middle part of the upside oral area of ash silo, upper strata bypass return line equipped with swollen Upper strata bypass valve plate sealing gasket is studded with upper strata bypass valve plate below swollen section and reflux tube valve, upper strata by-passing valve lip, on It is cased with upper strata bypass valve rod spring, unloading valve body being provided with lower floor's bypass pipe, lower floor's bypass on valve rod under layer bypass valve plate The bottom of pipe is provided with lower floor's by-passing valve lip, and the bottom of lower floor's by-passing valve lip is provided with by lower floor's bypass valve plate sealing gasket, lower floor It is provided with below port valve plate sealing gasket below lower floor's bypass valve plate, lower floor's bypass valve plate and lower floor's bypass valve rod bullet is installed Spring, the side of upper strata bypass valve plate support is enclosed on the downside that upper strata bypasses valve rod spring, and upper strata bypasses the opposite side of valve plate support It is fixed on the upper valve shaft on Double-deck cinder discharge valve body, the side of lower floor's bypass valve plate support is enclosed on lower floor's bypass valve rod spring Downside, the opposite side of lower floor's bypass valve plate support is fixed in lower valve board shaft.

Operation principle：When unloading valve body starts discharging, upper valve shaft starts band while rotation drives upper valve plate opening Dynamic upper strata bypass valve plate is opened, and starts the gas sucked in unloading valve body, is made in the air pressure and upside ash silo in unloading valve body Negative pressure is equal, and forming upside ash silo, hanging does not fall naturally, and they are simultaneously closed off upon closing, lower valve after upper valve plate is closed Board shaft starts Unscrew, drives lower valve plate to drive lower floor's bypass valve plate to open while opening, starts suction unloading valve external Air enter valve body in, make the negative pressure in valve body equal with the atmospheric pressure of outside, formed valve body in material by deadweight to flow down Drop down, obtain the purpose of free blowing.

The beneficial effects of the utility model are that the utility model equal pressure Double-deck cinder discharge valve can put ash freely, not by ash silo How much material position limits, and reduction puts grey frequency saving manually, reduces warehouse with valve body by material and gas shock abrasion, greatly extends The service life of unloading valve and ash silo, reduces the workload safeguarded to it, saves maintenance cost.
