Existing the ball type pulverizer system only has wood scraps separator, can not isolate the iron filings in coal dust.In coal dust iron filings have following obvious harm: 1, increase the wearing and tearing of pipeline, mass data shows that wearing and tearing are mainly by the high particle of hardness, tube wall to be washed away and caused, for a wind pipeline, pulverized coal particle hardness is more lower than pipe material, although quantity is many, wearing and tearing are little, in coal dust, iron filings hardness is substantially the same with conduit hardness, and a small amount of existence will produce larger wearing and tearing to a wind pipe wall.2, increase the danger of boiler water wall coking, in coal dust, iron filings, at hearth combustion, can be oxidized to ferrous oxide, greatly reduce fusion point of ash, thereby cause soot particle clashing into before water screen tube or molten condition, greatly increase the danger of boiler water wall coking.
At present, still not having can be for the problems referred to above and the iron filings separator of specialized designs invention.
Utility model content
The utility model provides a kind of device that iron filings in the coal dust of the ball type pulverizer system can be separated and reclaimed for the problems referred to above.
It adopts following technical scheme:
A kind of electromagnetism separates the equipment that reclaims iron filings, it comprises switch board, separator cylindrical shell, lower tube connector, collector of iron scraps, upper tube connector and electromagnet, described separator cylinder inboard wall periphery arranges electromagnet, top arranges tube connector, bottom arranges collector of iron scraps, described collector of iron scraps is oblique conical shell, its upper end is fixedly connected with the bottom margin of separator cylindrical shell, described lower tube connector extend into separator inner barrel through collector of iron scraps, and vertical corresponding with upper tube connector, described electromagnet is connected with switch board by the energising of switch board control electromagnet or power-off.
As further improvement of the utility model, also comprise iron filings memory, described iron filings memory is connected with the port of export of collector of iron scraps by carrier pipe.
As further improvement of the utility model, on described carrier pipe, be provided with valve.
As further improvement of the utility model, described valve adopts push-pull valve.
As further improvement of the utility model, the bottom discharging opening of described upper tube connector is inwardly conical and shrinks, and its lowermost end outlet internal diameter is less than the import internal diameter of described lower tube connector.
Good effect of the present utility model is as follows:
The utility model is in the time of coal dust process separator cylindrical shell, electromagnet can be isolated most iron filings in coal dust, the wearing and tearing of an airduct can be greatly alleviated, can reduce again the coking danger of boiler water wall, and can reclaim a large amount of iron filings, to the intermediate storage formula pulverized coal preparation system of 300,000 units, approximately 140 tons of year recyclable iron filings.Reduce the harm of iron filings in coal dust, iron filings can be recycled again, create extra benefit simultaneously.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In the accompanying drawings: tube connector, 9 electromagnet on 1 switch board, 2 separator cylindrical shells, 3 times tube connectors, 4 iron filings memories, 5 valves, 6 carrier pipes, 7 collector of iron scraps, 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of electromagnetism as shown in Figure 1 separates the equipment that reclaims iron filings, it comprises separator cylindrical shell 2, upper tube connector 8 and lower tube connector 3, described upper tube connector 8 entrance points are connected with the powder sinking tube of coal dust, upper tube connector 8 diameters are less than separator cylindrical shell 2 and coaxially arrange with separator cylindrical shell 2, described separator cylindrical shell 2 inwall peripheries are provided with electromagnet 9, described electromagnet 9 is connected with switch board 1, controlled the break-make of the electric current of electromagnet 9 by switch board 1, on described switch board 1, be provided with corresponding shift knob.
Described upper tube connector 8 and line tube connector 3 are straight-tube shape, and the bottom discharging opening of upper tube connector 8 is inwardly conical and shrinks, and its lowermost end outlet internal diameter is less than the import internal diameter of described lower tube connector 3.
The shape of described electromagnet 9 is according to the shape design of the concrete shape that falls to being in charge of and separator cylindrical shell 2.In the present embodiment, powder sinking tube is cylindrical, and separator cylindrical shell 2 is greater than the column-shaped barrel of powder sinking tube for diameter, and described electromagnet 9 is circular arc.
Described separator cylindrical shell 2 bottoms arrange collector of iron scraps 7, described collector of iron scraps 7 is oblique conical shell, its upper end is fixedly connected with the bottom margin of separator cylindrical shell 2, described lower tube connector 3 extend into separator cylindrical shell 2 inside through the bottom of collector of iron scraps 7, and vertical corresponding with upper tube connector 8.The import of lower tube connector 3 exceeds the lower edge of separator cylindrical shell 2, and lower tube connector 3 is fixedly connected with collector of iron scraps 7, and the outlet of lower tube connector 3 is connected with powder sinking tube.
The outlet of described collector of iron scraps 7 is connected with iron filings memory 4 by carrier pipe 6, is provided with valve 5 on carrier pipe 6, and described valve 5 adopts push-pull valve.Described push-pull valve can adopt startup push-pull valve, by the action of Long-distance Control cylinder, can realize the switching of valve, needn't operate at the scene.
