Description
Technical field
A kind of two-stage sealing valve plate type ash discharging gear is the utility model is related to, is used more particularly to a kind of lime shaft kiln
The board-like ash discharging gear of two-stage all closed valve, belongs to limekiln equipment technical field.
Background technology
In the production process of lime shaft kiln, whether good seal is to ensure air feed in lime production continuity and kiln to kiln bottom
The key of uniformity, lime shaft kiln ventilation apparatus are typically all arranged on kiln bottom portion, if kiln bottom sealing difference, because of air supply device
Near from kiln bottom, wind just can all be run out of from kiln bottom portion, and the air quantity supplied in kiln will be reduced, while substantial amounts of heat also can with the wind one
Rise and run out of out of kiln, cause the waste of energy consumption.The ash discharge water-tight equipment commonly used on the market now has star ash hoist, two sections of sealings
Valve etc., star ash hoist must have gap, otherwise can not rotate because its structure type limits between rotating cylinder and barrel, thus nothing
Method accomplishes to be fully sealed.Two sections of sealing valves are realized from principle by the alternating opening and closing of two sections of valves seals ash discharge, and common two
Section valve uses motor drive mechanism, and motor range powers off afterwards in place, and sealing between valve plate and sealing ring does not have pressure, but actually uses
Due to only having one section of valve housing memory capacity small in journey, efficiency is low, and the high dirt of working environment causes that limit switch is unreliable, sealing ring
It is easy to aging be hardened, the problems such as seal pressure is small, does not often have the sealing effectiveness of requirement yet.
The content of the invention
The purpose of this utility model is to overcome above mentioned problem present in current limekiln ash discharging gear, there is provided a kind of
Two-stage seals valve plate type ash discharging gear.
To realize the purpose of this utility model, following technical schemes is employed：A kind of two-stage sealing valve plate type ash discharge dress
Put, including upper box, lower box, upper box, which tilts, to be installed on below body of heater feed bin, and lower box is arranged at top box body side surface lower end
Portion, charging aperture is set in the top box body side surface first half, middle discharging opening is set in the joint portion of upper box and lower box, in
Between discharging opening upper box and lower box is penetrated, lower box bottom is provided with lower discharge port, and it is defeated that lower discharge port is located at ash discharge

Actively advantageous effects of the present utility model are：First, seal pressure is big：This sealing valve type ash discharging gear drives
Dynamic used cylinder operation pressure remains this in more than 0.4Mpa when cylinder seals after valve plate is brought into close contact with sealing ring in place
Pressure.And two sections of common valves use motor drive mechanism, motor range powers off afterwards in place, seals and is not pressed between valve plate and sealing ring
Power；Second, detection means is more reliable, using proximity switch detection valve plate, situation, proximity switch favorable sealing property are very suitable in place
The occasion big for this dust, adds equipment reliability of operation；Third, the lumpiness of lime can be kept：In ash discharge process
In, the equipment such as spiral ash hoist, gear ash hoist, slide valve ash hoist, in ash discharge all can severe crush ash block, percentage of damage reaches
More than 40%, and the hermetically sealed valve type ash discharge equipment of two-stage is freely to fall to discharge out of the furnace by the deadweight of grey block, is maintained to greatest extent
The lumpiness of lime.
