Abstract
The utility model provides a manual measuring tool of TFT liquid crystal glazing furnace flue draft, includes gas pressure gauge and the alundum tube of being connected through rubber tube and gas pressure gauge, division there is the measuring aperture in the position department of awaiting measuring of furnace flue, installs the alundum tube of being convenient for on the measuring aperture and carries out the measuring guiding tube inside stretching into the furnace flue, installs the flashboard on the guiding tube. The utility model discloses can be under the prerequisite that does not influence kiln normal operating and the work of flue automatic measure draft appearance, discharge fume systematic privileged site at the kiln and carry out manual draft and measure, convenient to use is swift, can greatly improve the measurement of efficiency of draft, judges for the accuracy that the operational aspect of flue is provided the basis, reduces the blindly operation of relevant inspection clearance flue, does not influence the stove internal pressure, and it is undulant to avoid appearing the stove internal pressure.
Description
Technical field
This utility model belongs to tft liquid-crystalline glasses and manufactures field and in particular to a kind of tft liquid-crystalline glasses furnace flue draft
Manual measurement instrument.
Background technology
During the manufacturing of tft liquid-crystalline glasses, in order to ensure the refining quality of vitreous humour, tank furnace adopts electrode to lead to
Electric heating melts to frit, and the size variation of tank furnace furnace pressure affects the change of vitreous humour liquid level height, and glass
The liquid level change of glass liquid then can be to glass production adverse effect, and being normally carried out of operation is melted in not only impact, also directly affects into
The stablizing of type technique, simultaneously liquid fluctuating cross the erosion that conference aggravates melting furnaces pool wall refractory material.It is thus desirable to flue draft
Measure.
At present, to adopting automatic measurement system the measurement of flue draft, its operation principle is domestic technique: this system is adopted more
Extract the fluctuating signal of flue gas in flue pressure with little differential pressure sensor, input a signal into pc machine through data collecting card, by pc machine
Carry out correlation computations to gathered data, try to achieve the instantaneous pressure value in flue, and transmit a signal to dcs system being shown.
But this metering system there is also many weak points, such as draft automatic measurement system is it sometimes appear that exceed
Measurement range, does not have the situation of data display, once in addition this system installation, the also just fixation of draft measurement position, if
Need to measure the draft of other positions, just cannot be carried out, be exactly also that automatic measurement system cost is high, performance and price compares
Difference.
Utility model content
The purpose of this utility model is for above-mentioned the problems of the prior art, provides a kind of tft liquid-crystalline glasses kiln
Flue draft manual measurement instrument, on the basis of not affecting furnace pressure, can be rapidly completed the measurement needs of ad-hoc location.
To achieve these goals, the technical solution adopted in the utility model is:
The alundum tube be connected including gas gauge and with gas gauge, has survey at the position to be measured of furnace flue
Metering-orifice, measured hole is provided with and is easy to alundum tube and stretches into the guiding tube measuring inside furnace flue, and guiding tube is installed lock
Plate.
Described gas gauge is connected by rubber tube with alundum tube.
Described rubber length of tube is 500mm.
It is 200mm that described guiding tube adopts length, the stainless steel tube of a diameter of 20mm.
Described corundum length of tube is 500mm.
Described gas gauge measurement range is 0～400pa.
Compared with prior art, this utility model can not affect the normal operation of kiln and flue automatic measurement draft
On the premise of instrument work, carry out manual draft measurement in the specific part of kiln smoke evacuation system, by entering with automatic measured data
Row monitoring contrast is it is ensured that kiln smoke evacuation system normally runs.This utility model can freely be installed on production scene and be actually needed
The position of manual measurement, flashboard can be airtight or open guiding tube, prevents air pressure from sending out by measured hole when not measuring
Raw leakage.This device is convenient to use, can be greatly enhanced the measurement efficiency of draft, for accurately judging the operation feelings of flue
Condition provides foundation, reduces the blindness operation that coherence check cleans flues, does not affect furnace pressure, it is to avoid furnace pressure ripple
Dynamic.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Referring to Fig. 1-5, this utility model includes gas gauge 1 in structure and passes through rubber tube 2 and gas pressure
The alundum tube 4 that table 1 connects, has measured hole at the position to be measured of furnace flue, measured hole is provided with and is easy to alundum tube 4 and stretches into
The guiding tube 3 measuring inside furnace flue, guiding tube 3 is installed flashboard 5.
Wherein, the length of rubber tube 2 is 500mm, and it is 200mm that guiding tube 3 adopts length, the rustless steel of a diameter of 20mm
Pipe, alundum tube 4 length is 500mm.The measurement range of gas gauge 1 is 0～400pa.
This utility model is in use it is necessary first to check the company of rubber tube 2, alundum tube 4 and gas gauge 1
Whether intact connect, more whether the pointer of inspection gas gauge 1 of blowing in alundum tube 4 swings normally；Then survey crew will
The flue of particular needs measurement is stretched into from guiding tube 3 in alundum tube 4 one end in specific purpose tool, observes the pointer pendulum of gas gauge 1
Emotionally condition, continues 5 minutes, records measured value three, and calculates meansigma methodss, as the draft value of flue at this.
Main advantages of the present invention are: can be specific in furnace flue while flue automatic draft instrument normally runs
Position is carried out draft measurement manually, thus automatic measured data is monitored contrast it is ensured that kiln smoke evacuation system just
Often run.
