Abstract
The utility model discloses a floating brick detection device for an image analysis type float glass tin bath, which is characterized in that the utility model comprises a front end videography probe and an image processing and alarming system of a background computer, wherein the image processing and warning system is arranged in the background computer, and the videography probe is electrically connected with the background computer. The videography probe comprises a cooling water jacket which is provided with a water inlet pipe and a water outlet pipe which are used for cooling water to flow. The utility model can automatically recognize the floating bricks in the tin bath and can give alarm.
Description
Technical field
The utility model belongs to field of glass production technology, particularly relates to a kind of float glass tin bath and floats the brick detector.
Background technology
In float glass, molten tin bath is the profiled section of glass.Whole molten tin bath is that a length is 30-60 rice, and width is the sealing member of 5-9 rice, and shell is a steel construction, and inner casing is a lagging material.Bottom in the molten tin bath is the insulating brick (being called the bottom land brick) of one deck level, is the tin of a melting layer above the insulating brick, is full of nitrogen, hydrogen mixed gas in the groove, to prevent the tin liquor oxidation.
Raw material is fused into glass metal in melting furnaces after the flow liquid road enters molten tin bath, because the proportion of tin is more great than the ratio of glass metal, so glass metal can shakeout on the fused tin liquor.The temperature in of molten tin bath is about 1080 ℃, and temperature progressively reduces backward, about 600 ℃, the climbing that make progress is arranged in order to avoid tin liquor outflow at the exit end of molten tin bath to the temperature in exit.Therefore glass metal is from the molten state that enters molten tin bath temperature step-down gradually backward, and coagulation forming becomes sheet glass, enters annealing furnace by tin bath outlet through the transition roller platform.Glass mainly is to rotate the drawing gravitation provided by roller-way in transition rod platform and the annealing furnace by the motion behind the forward direction in molten tin bath.
If in the moulding process of above-mentioned glass, cause glass ribbon in molten tin bath, to rupture (being called disconnected plate) for a certain reason, consequently the glass ribbon of the back roller-way drawing that can be annealed kiln goes out molten tin bath, the glass ribbon of front then can be owing to there not being pulling force not go out molten tin bath, Here it is usually said disconnected plate.If can in time handle, can not cause heavy losses to producing usually, but as can not in time finding and handle, glass will be piled up in molten tin bath so, causes usually said tankful accident.If the tankful accident has taken place, just need operator to open the handle hole of molten tin bath both sides, tens tons glass in the molten tin bath is drawn out the outside, the processing of this class accident needs several hours usually at least, and is long then need several days.The loss of the stopping production that the tankful accident causes and the loss of tin, electricity, the loss of equipment etc., its financial loss is hundreds of thousands of at least, and is millions of at most.Therefore say that tankful is a kind of Serious Accident that should avoid as possible in the float glass.
It is several to cause the reason of the disconnected plate of tin groove inner glass to have, and it is that big inclusion is arranged on the tin groove inner glass band that a kind of reason is wherein arranged.This might be from the refractory materials that comes off in the melting furnaces, or the bottom land brick fragment that floats up bottom the molten tin bath.Generally can this thing happens in normal production; but at the operation initial stage with arrived later stage in kiln age; usually having refractory brick in the melting furnaces comes off and falls in the glass metal and flow into molten tin bath; and molten tin bath has once in a while also in the later stage in kiln age that bottom land brick fragment comes off and floatingly comes up; as these situations of untimely discovery, the danger that causes disconnected plate, tankful accident will be arranged.So in time find inclusion big on the tin groove inner glass band, be the prerequisite of avoiding this class accident to take place.
In the prior art, lack the detection means to similar inclusion, can only rely on operator's visual inspection, the reliability of monitoring is difficult to guarantee, causes omission easily and disconnected plate, tankful accident take place.
Summary of the invention
To be solved in the utility model is to floating the detection problem of brick in the molten tin bath, providing a kind of automatically-monitored float glass tin bath to float the brick detector.
For this reason, the utility model has adopted following technical scheme: image analysis formula float glass tin bath floats the brick detector, it is characterized in that it comprises a front end camera probe and background computer picture processing and warning, wherein picture processing and warning are installed in the background computer, and camera probe is electrically connected with background computer; Camera probe includes a watercooling jacket, water inlet pipe and water outlet pipe is arranged for flow of cooling water on the water jacket.
Further, the utility model also comprises a gas purging mouth, purges mouth and places the camera probe front end, and the nitrogen that can blow out cleaning is in order to avoid the camera lens pollution.
During the utility model work, camera probe is delivered to background computer with the realtime graphic of picked-up, by image processing system it is carried out analyzing and processing, when the molten tin bath bottom has the refractory brick fragment to come off, because the proportion of tin liquor is big more many than refractory brick, thus fragment can on float to the sheet glass bottom.Because the sheet glass of this moment also is in semi-solid state, so fragment can upwards eject sheet glass the distension bag of a projection, at this moment can see that by camera probe a bright spot with the sheet glass motion (for the big inclusion of other type, the bright spot with the sheet glass motion also can occur on image) appears in glass-board surface; Computer Image Processing and warning are discerned the bright spot whether glass-board surface has motion automatically.In case find to have with the sheet glass motion and greater than the motion bright spot of set(ting)value, promptly send guard signal and capture present image so that operator watch and judge and handle.
Because molten tin bath and around temperature quite high, camera probe can't be worked under this hot environment, so the utility model is provided with watercooling jacket, to the camera probe cooling, guarantees its works better; The nitrogen that the gas purging mouth blows out can keep the popping one's head in cleaning of inner lens can not influence the molten tin bath works better simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1.The utility model comprises camera probe 1 and background computer 2, and camera probe 1 is electrically connected with background computer 2, and image processing system and warning are installed in the background computer 2; Have watercooling jacket 3 outside the camera probe 1, water coolant flows to from import 4, and outlet 5 is flowed out, to camera probe 1 cooling; Before the fused silica glass 6 of camera probe, be provided with a nitrogen purging mouth 7, when work, blow out the nitrogen of cleaning in order to avoid eyeglass 6 is contaminated; Probe 1 an anterior spherical protective guard 8 in addition is installed in outside the molten tin bath with screw rod 9, nut 10 etc.; In molten tin bath, 16 is bottom brick of molten tin bath, and it is the molten tin bath exterior wall that tin liquor 15 and glass 14,13 are arranged in it, and its sidewall is provided with vision slit 12, has above for the screw 11 that usefulness is installed.Camera probe 1 is installed in outside the molten tin bath vision slit 12 by screw rod, nut etc., can monitor the situation in the molten tin bath, the picture transmission of being obtained is to background computer 2, by image processing system and warning it is handled, automatically report to the police during unusual circumstance, thus the detection that realization is floated brick to molten tin bath.
