Abstract
The utility model relates to a coal flattening plate with a failure detection function. The coal flattening plate comprises a coal flattening plate main body and a failure detection switch, wherein the coal flattening plate main body has a structure in which the middle is flat, two edges are convex and a streamline outer edge is formed; the side face of the coal flattening plate main body is provided with the failure detection switch with an alarming function; the coal flattening plate main body is positioned on the upper part of a belt conveying machine; and an installation bracket of which the position is adjustable is arranged on the coal flattening plate main body. The coal flattening plate can be used for pretreating the surface shape of coal dust which is exposed in the air, and moisture detection in coal is more accurate due to the piling shape of the treated coal dust; and according to the specific shape of the coal flattening plate, coal bed water is prevented from flowing to the edge of a belt, and the phenomena of belt deviation and blocking accidents are avoided.
Description
Technical field
The utility model relates to a kind of before coal charge moisture detects, and carries out the pretreated device of coal charge.
Background technology
The belt pulverized coal conveying is exposed to that appearance receives solar radiation for a long time in the air, and moisture evaporation is more, and the moisture on surface is on the low side; If rain, coal surface water branch is higher, and in addition, the coal surface also receives on every side pollutions such as dust easily; Therefore, the coal surface moisture is affected by environment bigger, can not represent the inner average moisture content of coal dust, secondly; Naturally the coal seam surface irregularity that forms influences the water content detection effect, and is last, high in the middle of the coal seam; The shape that both sides are low is unfavorable for maintaining added moisture, and the water droplet of surface sprinkling converges easily and flows to belt edge; Cause the coal dust excess moisture of belt edge, wet excessively coal dust is not easy to break away from belt at transfer point, causes belt deviation and putty accident easily.
At present,, moisture in coal also do not carry out pretreated device before being detected to being exposed to airborne coal dust surface configuration.
Summary of the invention
The purpose of the utility model provides a kind of flat coal plate that has fault detection capability; This device can carry out pretreatment to being exposed to airborne coal dust surface configuration; It is more accurate that the shape that the change coal dust is piled up detects moisture in coal; And the given shape of this device can prevent the coal seam watering to flow to belt edge, avoids the generation of belt deviation and putty accident.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
The flat coal plate that has fault detection capability comprises flat coal plate main body, fault detection switch, and described flat coal plate main body is the shape that the centre is flat, both sides are protruding, have the stream line pattern outer rim, and flat coal plate main body side is provided with the fault detection switch with warning function.
Described flat coal plate main body is positioned at belt conveyer top, and is provided with the mounting bracket of position-adjustable above the flat coal plate main body.
Compared with prior art, the beneficial effect of the utility model is:
1) flat, the protruding given shape in both sides in the centre of this device, the coal seam carried out pretreatment after, middle flat helps the measurement of moisture content of coal; The both sides projection; On the coal seam, form two grooves, can prevent the coal seam watering to flow to belt edge, avoid the generation of belt deviation and putty accident.Flat coal operation through this device makes the further uniformization in coal seam on the belt, reduces the coal weight change to adding the influence of water operation, and it is more steady to add the water operation.
2) installation site of flat coal plate can be adjusted arbitrarily; On the flat coal plate fault detection switch is housed, has flat coal plate fault diagnosis functions are installed, loosening or damage suddenly when flat coal plate; Can send alerting signal automatically, prevent that damaged flat coal plate from scratching belt or damaging upstream device.
3) flat coal plate has unique W shape and stream line pattern edge, be difficult for sticking coal when putting down coal, and its material is adapted at long-term work under the corrosive environment.
Description of drawings
Fig. 1 is the structural representation that has the flat coal plate of fault detection capability.
Among the figure: 1-mounting bracket 2-fault detection switch 3-puts down coal plate main body 4-belt conveyer 5-fixed mount
The specific embodiment
See Fig. 1; The flat coal plate that has fault detection capability; Comprise flat coal plate main body 3, fault detection switch 2, described flat coal plate main body 3 is the shape that the centre is flat, both sides are protruding, have the stream line pattern outer rim, and flat coal plate main body 3 sides are provided with the fault detection switch 2 with warning function.Flat coal plate main body 3 is positioned at belt conveyer 4 tops, and is provided with the mounting bracket 1 of position-adjustable above the flat coal plate main body 3, and mounting bracket 1 is arranged on the fixed mount 5.
Described fault detection switch 2 is for having the travel switch of contact; During normal operation, the contact is a closure state, when flat coal plate becomes flexible or damages suddenly; The contact of the travel switch that compresses with flat coal plate becomes off-state; Contacts status can send alerting signal after changing automatically, prevents that damaged flat coal plate from scratching belt or damaging upstream device.
The flat coal plate main body of this device has unique shape and stream line pattern edge; Be difficult for sticking coal when putting down coal,, not only help accurately carrying out moisture content of coal and measure through the flat coal plate body shape of unique design; Can also prevent the coal seam watering to flow to belt edge, avoid the generation of belt deviation and putty accident.
Claims (2)
1. the flat coal plate that has fault detection capability; It is characterized in that; Comprise flat coal plate main body, fault detection switch, described flat coal plate main body is the shape that the centre is flat, both sides are protruding, have the stream line pattern outer rim, and there is the fault detection switch with warning function flat coal plate main body side.
2. the flat coal plate that has fault detection capability according to claim 1 is characterized in that, described flat coal plate main body is positioned at belt conveyer top, and is provided with the mounting bracket of position-adjustable above the flat coal plate main body.
