Abstract
The utility model discloses a kind of blow tank conveying system anti-block apparatus, including storehouse pump main body and the ash conveying pipe for being placed in storehouse pump main body bottom, ash conveying pipe side wall is provided with ash inlet, anti-blocking watt is provided with ash inlet, anti-blocking watt is fixedly installed in ash conveying pipe, a compressed air channel penetrating all the time is set up in ash conveying pipe under the pump of storehouse, ensure that compressed air is unimpeded, prevent flyash from blocking completely, compressed air channel is smaller, flow velocity is bigger, impact to flyash is also bigger, can ensure that and never block, substantially increase defeated grey efficiency, save a large amount of manpower and materials.
Description
Technical field
The utility model is related to thermal power generation plant to manufacture and design field, and in particular to a kind of blow tank conveying system is anti-blocking
Device.
Background technology
At present, what the ash-transmission system in thermal power plant was used be top charging, the storehouse pump of bottom discharge, flyash from
Top is fallen into the pump of storehouse, and flyash is fed forward to grey storehouse by the pipeline compressed air after the pump of storehouse, is passed through during defeated ash
The situation of flyash accumulation can be often run into, the situation for causing ash-transmission system to block, when flyash is piled up, compressed air conveying fine coal
Ash is just relatively difficult forward, and resulting in blockage to convey, and maintenance difficulty is big, labor intensive material resources.
Utility model content
The utility model aims to provide a kind of blow tank conveying system anti-block apparatus, to solve the defeated ash in existing thermal power plant
Line clogging cause equipment dependability or utilization rate rate is low, maintenance cost increases, labor intensive the problems such as.
The utility model is achieved by following technical solution：
A kind of blow tank conveying system anti-block apparatus, including storehouse pump main body and the ash conveying pipe for being placed in storehouse pump main body bottom, institute
State ash conveying pipe side wall and be provided with ash inlet, anti-blocking watt is provided with ash inlet, anti-blocking watt is fixedly installed in ash conveying pipe.
Described anti-blocking watt is strip arc tile structure, and its arc opening is down.
Described anti-blocking watt is located at ash inlet centre position, and two ends are fixed in ash conveying pipe.
The anti-blocking watt of arc radius are less than ash conveying pipe radius.
The beneficial effects of the utility model are：
Compared with prior art, a kind of blow tank conveying system anti-block apparatus that the utility model is provided, it is defeated under the pump of storehouse
Grey pipeline is built-in to found a compressed air channel penetrating all the time, it is ensured that compressed air is unimpeded, prevents flyash from blocking completely, pressure
Contracting air duct is smaller, and flow velocity is bigger, and the impact to flyash is also bigger, it can be ensured that never block, and substantially increases defeated ash effect
Rate, saves a large amount of manpower and materials.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is anti-blocking schematic diagram of the present utility model；
In figure：1- storehouses pump main body, 2- ash conveying pipes, anti-blocking watt of 3-, 4- ash inlets, 5- pressurized airflow paths.
Specific embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not
It is confined to described；
As shown in Figure 1, 2, a kind of He of blow tank conveying system anti-block apparatus of the utility model offer, including storehouse pump main body 1
The ash conveying pipe 2 of the bottom of storehouse pump main body 1 is placed in, the side wall of the ash conveying pipe 2 is provided with ash inlet 4, anti-blocking watt is provided with ash inlet 4
3, anti-blocking watt 3 is fixedly installed in ash conveying pipe 2, and in flyash falls ash conveying pipe 2 under storehouse pump main body 1, anti-blocking watt 3 will
Ash inlet 4 is divided into two passages, and anti-blocking watt 3 underface then reserves a pressurized airflow path 5, and one is to effectively reduce fine coal
The flow velocity of ash, two is that the flyash that will quickly can be fallen is transported away, realizes not stifled effect.
Described anti-blocking watt 3 is strip arc tile structure, and its arc opening down, keeps arc row mouthful immediately below it, due to
Flyash natural packing has certain angle of repose, even if the ash conveying pipe 2 that flyash is filled with lower section also will not be completely plugged
Arc space under anti-blocking watt 3, when flyash falls into starts conveying in storehouse pump main body 1, because the anti-blocking watt of arc of 3 bottoms is empty
Between be not completely filled with flyash always, compressed air channel exists all the time, and when passage is smaller, compressed air flow velocity is faster, pressure
Contracting air flows from high-pressure area to depression, drives flyash to travel forward.Because this compressed air channel is deposited all the time
, conveying just carry out always, pipeline would not be blocked.
Described anti-blocking watt 3 is located at the centre position of ash inlet 4, and two ends are fixed in ash conveying pipe 2, and anti-blocking watt 3 by ash inlet 4
It is divided into and a pressurized airflow path is then reserved immediately below two passages of the right and left, anti-blocking watt 3, realization is never blocked.
Anti-blocking watt of 3 arc radius are less than the radius of ash conveying pipe 2, and anti-blocking watt of 3 arc lengths are the 1/3 of girth, in order to avoid
Block ash inlet 4 for anti-blocking watt 3.
