Description

The storage ash storehouse dust unloadnig apparatus structure of band anti-block apparatus
Technical field
The utility model relates to the dust unloadnig apparatus structure that a kind of thermal power plant dry ash stores up grey storehouse, a kind of specifically storage ash storehouse dust unloadnig apparatus structure with anti-block apparatus.
Background technology
The dry ash that forms behind the coal combustion of thermal power plant is transported to dry ash and stores up grey storehouse, stores up grey lab setting and becomes the cylindrical of 12 meters of diameters, 26 meters of height, and storing up in the grey storehouse is between the storage ash more than 10 meters, and arrange between 6 meters and 10 meters and unload grey equipment, below 6 meters other accessory equipments.The midway location place of bottom surface is provided with two circular cinder-discharging ports between the storage ash.Also evenly be furnished with the gasification board of some strips on the bottom surface of storage between ash, gasification board is arranged on the cement platform of bottom surface between the storage ash, and from the edge that stores up bottom between ash the oblique cinder-discharging port that points to midway location down.Be arranged in gasification board bonded assembly roots blower and unload grey mechanical floor, roots blower is communicated with the inlet of some gasification boards by the pre-buried pipeline in the cement platform, moving air enters the uniform dry ash bottom that is blown into from the gasification board surface between the storage ash in back from the inlet of gasification board, makes the dry ash bottom be in suspended state.Dry ash is transported to the grey equipment that unloads from cinder-discharging port by the ash-unloading tube road.Because the ash amount that thermal power plant produces is bigger, the often long-time high position of dry ash is stored in the grey storehouse, time one, long dry ash made moist and the phenomenon that occurs hardening easily, dry ash after hardening forms bulk, at this moment the moving air that is blown into from gasification board has just lost effectiveness, block dry ash falls and is deposited in cinder-discharging port, stops up cinder-discharging port, causes that to unload ash not smooth.And because all sealings more than 10 meters of the grey storehouse of storage, the repair and maintenance personnel can't enter in the grey storehouse of storage, in case after dry ash device knot stops up cinder-discharging port, bring very big trouble can for the repair and maintenance personnel.
The utility model content
The utility model technical issues that need to address provide the storage ash storehouse dust unloadnig apparatus structure that the band anti-block apparatus of grey storehouse cinder-discharging port obstruction is stored up in a kind of effective solution.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The storage ash storehouse dust unloadnig apparatus structure of band anti-block apparatus, comprise the grey storehouse of storage, cinder-discharging port, gasification board, blower fan, the top in the grey storehouse of columniform storage is provided with between the storage ash, circular cinder-discharging port is arranged on the midway location of the bottom between the storage ash, the gasification board of some strips is evenly arranged in the bottom between the storage ash, and from storing up the oblique cinder-discharging port that points to down of bottom margin between ash, the blower fan that is arranged in the below between the storage ash is communicated with the inlet of gasification board, be provided with above the described cinder-discharging port by what support post and tapered cap were formed and unload grey anti-blocking umbrella crown, the upper end captive joint tapered cap of support post, the lower end of support post be fixedly connected on cinder-discharging port around.
Further improvement of the utility model is: described support post is three uniform I-beam sections.
Because the technological advance that has adopted technique scheme, the utility model to obtain is:
The utility model is provided with above the cinder-discharging port of bottom between the storage ash in the grey storehouse of former storage and unloads grey anti-blocking umbrella crown, scene when the grey storehouse of storage is built can be welded by three I-beam sections and a tapered cap, and fabrication and installation are easy, can use the engineering leftover bits and pieces, do not need special material, economize on resources.Unload grey anti-blocking umbrella crown and can effectively stop of the gathering of block dry ash at circular cinder-discharging port, avoid the obstruction of cinder-discharging port, increased the flowing space of cinder-discharging port place dry ash, the moving air that in addition is blown into from the gasification board that is in tilted layout has guaranteed to store up grey storehouse and has unloaded the smooth and easy of ash again.The utility model is simple for production, economize on resources, effect is remarkable, can solve thermal power plant and store up the blockage problem that ash is unloaded in grey storehouse, provide safeguard for unloading ash smoothly, reduced repair and maintenance personnel work capacity, and of the present utility modelly unload grey anti-blocking umbrella crown and not only can be applied in storage grey storehouse ash discharging system, also can be applied in the discharge system of other granular material storage vaults.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of bottom between the storage ash.
Wherein, 1, between the storage ash, 2, gasification board, 3, support post, 4, tapered cap, 5, cinder-discharging port, 6, unload grey equipment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
The storage ash storehouse dust unloadnig apparatus structure of band anti-block apparatus comprises the grey storehouse of columniform storage, stores up grey storehouse and is divided into three layers from top to bottom, is followed successively by between the storage ash 1, unloads grey mechanical floor, zero rice layer.The midway location of 1 bottom is arranged the cinder-discharging port 5 of two circles between the storage ash.The gasification board 2 of some strips is distributed on the cement platform of 1 bottom between the storage ash, and from storing up the oblique cinder-discharging port 5 that points to down of bottom margin between ash, this leaning angle is 8 degree.The blower fan that is communicated with gasification board 2 is arranged in and unloads grey mechanical floor, blower fan is communicated with the inlet of some gasification boards 2 by the pre-buried pipeline in the cement platform, moving air enters the back from the inlet of gasification board 2 and is blown between the storage ash 1 dry ash bottom uniformly from the gasification board surface, makes the dry ash bottom be in suspended state.Grey anti-blocking umbrella crown is unloaded in the top setting of described cinder-discharging port 5.Unloading grey anti-blocking umbrella crown and be made up of support post 3 and tapered cap 4, captives joint with tapered cap 4 in the upper end of support post 3, the lower end of support post 3 be fixedly connected on cinder-discharging port 5 around.Support post can be three or four, and can directly use the leftover bits and pieces of engineering to be welded, for example I-beam section.Cinder-discharging port 5 unloads grey equipment 6 by the feeding pipe connection, and dry ash enters the grey equipment 6 that unloads by cinder-discharging port 5.
