Description

Automatic slag discharge device for coal ash for unloading of coal ash tank truck

Technical Field

The utility model relates to a fly ash is unloaded and is used the equipment field, especially a fly ash automatic row's sediment device that is used for fly ash tank car to unload.

Background

The fly ash entering a factory contains a lot of impurities such as steel slag, so the fly ash needs to be filtered, the filter screen is generally arranged at the position of a warehousing pipeline in the conventional filtering process, but the filter screen is too much in the fly ash entering the factory, the warehousing pipeline is easy to block particularly at the filter screen, the filling vehicle is subjected to pipe explosion, the field ash expansion is serious, and the filtered fly ash enters fly ash warehouse-out equipment of a cement grinding system of a cement factory, the filter effect of the filter screen is not ideal, the blocking phenomenon is often caused, the fly ash mixing amount is influenced, and even the mill cannot be stopped due to the fact that the fly ash cannot be mixed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an automatic sediment device of arranging of fly ash for fly ash tank car is unloaded, it is poor not only the filter effect to solve the filter equipment on the present fly ash warehouse entry time warehousing pipeline, and appears the pipe explosion phenomenon easily and the scene serious problem of ash that rises.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides an automatic sediment device of arranging of fly ash for fly ash tank car is unloaded, includes sieve material box, counterattack board and scum pipe, the bottom of sieve material box is the feed inlet, and feed inlet department is equipped with the inlet pipe, and the top of sieve material box then is the discharge gate, and discharge gate department is equipped with the discharging pipe, the inlet pipe of sieve material box links to each other with fly ash tank car's fly ash discharging pipe, and the discharging pipe of sieve material box then links to each other with the pipeline of putting in storage, the counterattack board sets up directly over the feed inlet of sieve material box, leave the fly ash passageway around the counterattack board and between the inner chamber face of sieve material box, the scum pipe sets up the both sides at sieve material box bottom inlet pipe, the lower extreme of scum pipe links to each other with the lower part of inlet pipe.

The filter screen is replaced by the screen material box body, the impact plate and the slag discharge pipe, when the fly ash enters the screen material box body, the particle size is large, heavy impurity materials can fall downwards under the blocking of the impact plate, the powder can not fall but can continue to enter a storage pipeline along with the air flow from a fly ash channel between the impact plate and the inner wall of the screen material box body, the falling particle size is large, the heavy impurity materials fall into an inlet pipe and are precipitated, the filtering effect is good, the screened fly ash contains less impurities, and due to the fact that the filter screen is not arranged, the blocking phenomenon can not occur, the pipe explosion of a filling vehicle can not be caused, and the situation that the ash rises on site is obviously lightened.

As a further preference of the utility model, the feed inlet of the screening box body is just to the discharge gate of the screening box body.

As a further preferred aspect of the present invention, the impact plate is tapered, and the top end of the impact plate is a tapered portion.

The arrangement can ensure that most of materials with heavy mass are blocked, and more materials with heavy mass enter the storage pipe through the impact plate if the lower end of the impact plate is a conical tip.

As a further preferred feature of the present invention, the outer periphery of the bottom surface of the reaction plate is provided with a slag trap.

Further reducing the probability of the impurities with heavy mass entering the storage tube.

As a further preferred feature of the present invention, the inlet pipe of the sieving box body is connected with the fly ash discharging pipe of the fly ash tank truck through a bolt, and the discharging pipe of the sieving box body is connected with the storage pipeline through a bolt.

As the utility model discloses a further preferred, the overfire air area of sieve material box is more than the triple of fly ash discharging pipe area of fly ash tank car.

Compared with the prior art, the utility model discloses can reach one in following beneficial effect at least:

1. the device changes the material movement track with large volume and heavy mass by means of material impact resistance, so that the material movement track is separated from the fly ash with light mass, the material with large volume and heavy mass is downwards collected and discharged by the impact plate, and the fly ash with light mass is taken away along with airflow, thereby achieving the purpose of automatically discharging slag and having good slag discharging effect.

2. Through the transformation of the automatic slag discharging device of the fly ash pipeline, the problem that the grinding efficiency is influenced when steel slag with larger particles enters a cement mill bin is solved.

3. Through the reformation of the automatic slag discharging device of the fly ash pipeline, the problems that an impurity filter screen installed in an original pipeline box is easy to block and damage and has poor effect are solved.

4. The soot blowing hose is not easy to bend.
