Abstract
The utility model discloses a double-layer cindervalve, which comprises two novel material delivery valves, wherein the two novel material delivery valves are superposed up and down; an ash storage silo is arranged between the two novel material delivery valves; and a discharging hole of an upper valve is fixedly connected with a feeding hole of a lower valve by the ash storage silo in the middle. The upper valve and the lower valve of the double-layer cindervalve are matched for action at the limit material position (or within the limit time), and the two valves keep the one-opening and one-closing state all the time, so as to ensure no air leakage of an ash discharging system. The double-layer cindervalve is applicable to discharging the ash for an electric deduster and a big flue of a sintering nose, dedusting and discharging the ash by the blast-furnace gas dry method and the like under the state of high negative pressure, and is the newest substitute product of a bell-shaped valve of a blast-furnace coal injection tank.
Description
Technical field
The utility model relates to the mass transport valve that uses in the systems such as a kind of Pneumatic ash conveying, defeated coal.
Background technology
At present, along with dry ash obtains comprehensive application more widely, the Pneumatic ash conveying technology has been widely used in aspects such as the defeated ash of dedusting of industries such as each big coal-burning power plant, steel mill and building materials, defeated coal.The domestic mass transport valve that is used for Pneumatic ash conveying, coal handling system, most " spherical valve " or " butterfly valve " these two kinds of forms that adopt, defective be its at work valve part be hard fitted seal mode, need reach every day under thousands of times unlatching, the situation of closing at valve body, add the friction of dust, the valve part wearing and tearing are very fast, leak tightness reduces, general service life, less than was three months, caused stopping production that maintenance is frequent, expense is high, had a strong impact on production efficiency.For the above-mentioned defective China utility model ZL 2004200977846.0 that overcomes the mass transport valve has disclosed a kind of novel material transfer valve, it is a kind of large-scale valve of new-type structure, what adopted is " air sac " seal form, when needing sealing the butterfly RunddichtringO is inflated, make it to expand and play sealing function, need to rotate when opening gas is laid down, the withdrawal of butterfly RunddichtringO, this moment, ball core valve and valve body formed the 1-1.5mm gap, how ball core valve rotates can not contact valve body generation wearing and tearing, thereby prolonged the service life of product greatly, prolong more than 10 times than traditional " spherical valve " and " butterfly valve ", and solved the problem that conventional valve is leaked gas because of wearing and tearing.But the defective that Chinese utility model ZL 2004200977846.0 described novel material transfer valves still exist ash discharging system to leak out when reality is used.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned shortcoming of novel material transfer valve, a kind of Double-deck cinder discharge valve to be provided.
For achieving the above object, the technical solution of the utility model is Double-deck cinder discharge valve, comprise two novel material transfer valves, the setting that superposes up and down of described two novel material transfer valves, the centre is provided with ash-storing bin, and the discharging opening of last valve is affixed with the inlet point of following valve by middle ash-storing bin.
Two novel material transfer valves that constitute Double-deck cinder discharge valve adopt the described novel material transfer valve of Chinese utility model ZL2004200977846.0.
Double-deck cinder discharge valve when work, the material level (or limiting the quantity of the time) of limiting the quantity of between the two valves up and down action that cooperatively interacts, during last opening of valves, following valve cuts out, and material enters ash-storing bin by last valve, goes up valve then and closes, and following opening of valves, the material in the ash-storing bin pass through to descend the valve discharge.All the time be in one one between two valves and close state, do not have air leakage phenomena to guarantee ash discharging system.Be specially adapted to sintering machine head end electric dust collector and large flue unload ash, blast furnace gas dry dusting unload under the grey contour negative pressure state to unload ash used, be the up-to-date substitute products of pulverized coal injection winding-up jar clock valve.
Description of drawings
Fig. 1 is the Double-deck cinder discharge valve structural representation
Among the figure: 1, go up valve, 2, go up the valve discharging opening, 3, valve down, 4, valve inlet point down, 5, ash-storing bin.
The specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
Embodiment as shown in Figure 1, Double-deck cinder discharge valve comprises two novel material transfer valves, the setting that superposes up and down of described two novel material transfer valves, the centre is provided with ash-storing bin 5, the discharging opening 2 of last valve 1 is affixed with the inlet point 4 of following valve 3 by middle ash-storing bin 5.
Claims (1)
1. Double-deck cinder discharge valve comprises two novel material transfer valves, it is characterized in that the setting that superposes up and down of described two novel material transfer valves, and the centre is provided with ash-storing bin, and the discharging opening of last valve is affixed with the inlet point of following valve by middle ash-storing bin.
