Abstract

The utility model discloses a defeated grey filter's device, the device comprises a device casing, install the grid in the device casing, be provided with on the device casing and draw the ash mouth, install the air inlet valve on the device casing, the welding of device casing lower part has the ash falling pipe and defeated grey pipeline, simple structure, and the structure is clearly understandable. The phenomenon that the suction and exhaust vehicle cannot suck due to the fact that impurities block the pipeline frequently in the process of conveying dust in the blast furnace environment by utilizing the pipeline is avoided; after installing defeated grey filter additional, utilize the grid in the defeated grey filter to separate debris and dust removal ash, open the ash hole of drawing on the defeated grey filter behind the debris too much and draw out debris, not only great reduction the secondary raise dust of defeated grey process, can also practice thrift because of the time of the defeated grey pipeline jam frequently draws out debris, shortened the suction and exhaust car operating time greatly simultaneously.

Description

Ash conveying filter device

Technical Field

The utility model relates to a dust removal, conveying and unloading field of a blast furnace environment, in particular to a device of a dust conveying filter.

Background

Along with the increasingly severe environment-friendly situation, the traditional 'humidifier and automobile' pull mode is easy to generate secondary dust. The mode of pipeline transportation and negative pressure suction and exhaust vehicle is widely used because the dust is not easy to generate secondary dust in the pipeline. However, once such impurities are sucked into the pipeline, the dust-removing vehicle cannot suck the dust-removing ash, and the impurities in the pipeline can only be detached by 2-3 people when the impurities cannot be effectively filtered, and the impurities in the pipeline are drawn out by using tools such as a through bar, so that time and labor are wasted, and secondary dust is easily generated on site.

Disclosure of Invention

An object of the utility model is to provide a defeated grey filter's device to solve the problem that proposes among the above-mentioned background art. After the ash conveying filter is additionally arranged, the sundries in the filter can be cleaned by only one person after the ash conveying filter is fully blocked by the sundries. The ash conveying filter is applied to the pipeline ash conveying process, so that the labor cost is reduced, the operation time of the suction and discharge vehicle is greatly shortened, and the suction and discharge time of 60 minutes per vehicle before modification is shortened to 20 minutes per vehicle.

In order to achieve the above object, the utility model provides a following technical scheme:

the device of the ash conveying filter comprises a device shell, wherein a grid is installed in the device shell, an air inlet valve is installed on the device shell, an ash drawing opening is installed on the device shell, and an ash conveying pipeline is welded on the lower portion of the device shell.

Preferably, a grating is arranged in the device shell, and the grating is obliquely arranged to increase the area for filtering sundries.

Preferably, an air inlet valve is installed on the shell of the device, and once the grille is full of sundries, the suction and exhaust vehicle cannot suck residual dedusting ash in the ash conveying pipeline. At the moment, the ash discharging valve is closed to prevent ash from being discharged, the air inlet valve is opened to prevent vacuum from being formed in the ash conveying pipeline, and residual dedusting ash in the pipeline is discharged.

Preferably, an ash falling pipe is installed between the shell of the device and the ash conveying pipeline, the pipe diameter of the ash falling pipe adopts a big end up mode, the effects of ash storage and buffering are increased, and the suction and discharge vehicle can suck the dedusting ash more easily.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, the structure is clear understandable, and through the grid in the device casing with debris and dust removal ash separation, the dust removal ash gets into and can play the cushioning effect in the ash pipe that falls, great reduction the secondary raise dust of defeated ash process, because of defeated ash pipe blockage frequently draws the time of debris, improved suction and exhaust car operation effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the present invention relates to an ash conveying filter device, which comprises a device housing 1, wherein a grating 3 is installed in the device housing 1, and the grating 3 is obliquely arranged. Install inlet valve 2 on the device casing 1, this inlet valve 2 is located 3 below of grid, install on the device casing 1 and draw grey mouth 4, the ash pipe 8 that falls is installed to device casing 1 lower part, and the pipe diameter of ash pipe 8 adopts big-end-up mode, has increased the effect of storing up ash, buffering, makes the suction and exhaust car inhale the dust removal ash more easily. An ash conveying pipeline 5 is welded below the ash dropping pipe 8, the upper part of the shell 1 of the device is connected with an ash discharging short pipe 6, and the ash discharging short pipe 6 is connected with an ash discharging valve 7 through a reducing pipe.

After the ash discharge valve 7 is opened and starts to work, if impurities are sucked into the device shell 1 and then are blocked on the grating 3, filtered dust can enter the lower device shell. Because the device casing is big-end-up, can store some through filtering the dust removal ash that does not contain debris, played certain cushioning effect, make suction car suction easier. Once the suction and exhaust vehicle is not used for sucking, the situation that sundries on the grating 3 are fully blocked is shown, the dust conveying pipeline is vacuumized by the suction and exhaust vehicle at the moment, the dust discharging valve 7 is closed, the air inlet valve 2 is opened to enable the dust conveying pipeline to continuously enter air from the outside, residual dust in the dust conveying pipeline is discharged, the dust drawing port 4 is slowly opened, the sundries on the grating 3 are drawn out until the sundries are drawn out, the dust drawing port 4 is closed, and the air inlet valve 2 is closed. And the ash discharging valve 7 is opened again, and a normal ash conveying program is installed for operation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
