Description

Ash discharging structure of ash bin

Technical Field

The utility model relates to a dust collecting equipment field especially relates to an ash structure under ash storehouse.

Background

In the production process of the metallurgical industry, high-temperature flue gas mixed with dust is often generated, and in the flue gas treatment process, the settled dust needs to be collected by an ash bin and then is transported to other treatment processes by a screw conveyor. In order to reduce the equipment, the ash outlets of a plurality of ash bins are generally communicated with the same spiral conveyor through a slide pipe, and then an ash discharge valve is arranged on the slide pipe for ash discharge control. The prior ash discharging structure mainly has the following problems: the chute is obliquely arranged, so that the dust and the chute are seriously abraded; the interface of the dust discharge valve is not tightly sealed, so that dust leakage is serious, raised dust is easy to generate, and the labor intensity of a post is increased; the dust removal valve and the dust discharge valve are seriously abraded, so that the replacement frequency of the dust discharge valve and the motor is overhigh; because the fly ash temperature is high, the motor is easy to burn out, the time for replacing the motor is too long, the cost is increased, and the production is influenced.

SUMMERY OF THE UTILITY MODEL

For overcoming the above-mentioned not enough that current ash discharging structure exists, the utility model aims to solve the technical problem that: the ash bin ash discharging structure is better in sealing performance, capable of reducing abrasion and convenient to overhaul and maintain.

The utility model provides a technical scheme that its technical problem adopted is:

ash structure under ash bin includes along the elephant trunk of vertical direction setting between ash bin and screw conveyer, be equipped with first unloading valve and second unloading valve on the elephant trunk, all be connected through the flange between first unloading valve and second unloading valve and the elephant trunk.

Furthermore, the first ash discharge valve and the second ash discharge valve are both manual butterfly valves.

Furthermore, the first ash discharging valve is a manual butterfly valve, and the second ash discharging valve is an electric ash discharging valve.

Furthermore, a water cooling tank is arranged between a motor and the valve body of the second ash discharge valve, a cold water coil is arranged in the water cooling tank, and a main shaft of the motor penetrates through the water cooling tank and then is connected with the valve body.

The utility model has the advantages that: the ash discharge chute is vertically arranged, so that the dust can vertically fall, the acting force between the ash and a pipeline is small, the chute is not easy to wear, and the dust can be effectively prevented from flying due to a leak caused by abrasion; through set up two unloading valves on the elephant trunk, one of them uses when overhauing as reserve, does not influence the normal clear of production to unloading valve and elephant trunk pass through the flange and are connected, and the leakproofness is good, is difficult for producing and leaks.

Marked in the figure as 1-ash bin, 2-screw conveyer, 3-chute, 4-first ash discharge valve, 5-second ash discharge valve, 6-flange, 51-motor, 52-valve body, 53-water cooling tank.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the utility model discloses an ash structure under ash storehouse, include along vertical direction setting elephant trunk 3 between ash storehouse 1 and screw conveyer 2, be equipped with first unloading valve 4 and second unloading valve 5 on the elephant trunk 3, all be connected through flange 6 between first unloading valve 4 and second unloading valve 5 and the elephant trunk 3.

The elephant trunk 3 that arranges with the tradition slope changes vertical setting into, makes the effort reduce between ash and the pipeline, is difficult for wearing through elephant trunk 3.

A first ash discharging valve 4 which is relatively higher than the chute 3 is used as a standby maintenance valve, and in the normal use process, the first ash discharging valve 4 is normally opened, and the ash discharging is controlled through a second ash discharging valve 5; when the second ash discharge valve 5 is worn and needs to be repaired, the first ash discharge valve 4 can be closed, and the first ash discharge valve 4 can be opened after the second ash discharge valve 5 is replaced.

Traditional unloading valve 4 is direct to be connected with elephant trunk 3 through the screw thread, and the leakproofness is not enough, and the time is a long time, just the dust leakage condition appears easily along with expend with heat and contract with cold and wearing and tearing. This application adopts flange 6 to connect, and the leakproofness is better, is more difficult to produce the dust and leaks.

The currently adopted ash discharge valve is generally controlled by a motor, has the advantages of convenient opening and closing control and high cost, is easy to damage at high temperature and is troublesome to repair and replace once damaged. Therefore, for reducing the cost, the first ash discharge valve 4 and the second ash discharge valve 5 can be set as manual butterfly valves, and are controlled manually, and although certain manpower and material resources need to be consumed, the advantages are low cost and precise adjustment and control of the opening degree.

If the cost is not considered, the electric dust discharging valve is still adopted, a water cooling tank 53 can be arranged between the motor 51 and the valve body 52 of the electric dust discharging valve, a cold water coil is arranged in the water cooling tank 53, and the main shaft of the motor 51 passes through the water cooling tank 53 and then is connected with the valve body 52. Because the heat that leads to motor 51 to damage mainly comes the heat of system dust ash, set up water-cooling tank 53 after, can reduce the heat that transmits motor 51 to play good guard action to motor 51, avoid because of high temperature damage increase of service life.

The utility model discloses at first through the vertical setting of ash elephant trunk under will, reduced the wearing and tearing of dust to the elephant trunk, then through setting up two unloading valves on the elephant trunk, conveniently overhaul and do not influence the normal clear of production, the unloading valve passes through the flange with the elephant trunk and is connected, and the leakproofness is good, is difficult for producing and leaks, adopts manual butterfly valve or increases the cooling water tank at last, has prolonged the life of unloading valve. Through the improvement, the probability of dust leakage and dust raising generated by the dust bin is greatly reduced, the labor intensity of workers is reduced, the production efficiency is improved, and the dust bin has good practicability and application prospect.
