Abstract
The utility model discloses a device for measuring permeation volume of air bricks. The output end of an air compressor is communicated with a buffer tank through a reducing valve, a ventilation pipeline on the buffer tank is connected with the bottoms of the air bricks, and the top of the air bricks is provided with an air speed detection device. The device for measuring permeation volume of the air bricks is simple in structure, easy to manufacture or reform, very convenient to operate, excellent and accurate in detection effect, and very beneficial for being popularized and implemented.
Description
Technical field
The utility model relates in field of steel-making the detection technique of air brick, is specifically related to a kind of air brick Air permenbility measurement mechanism.
Background technology
In field of steel-making, the ladle sidewall is provided with air brick, be connected with gas pipe line on air brick, so that to the technique of blowing in ladle, the intensity of air brick and permeability all need guarantee up to standard steel-making quality, for the detection of air brick gas penetration potential, a kind of simple to operate, effective instrument need to be arranged.
The utility model content
The purpose of this utility model is for air brick gas penetration potential test problems, and a kind of air brick Air permenbility measurement mechanism is provided.
The utility model is achieved through the following technical solutions: a kind of air brick Air permenbility measurement mechanism, and the output terminal of air compressor machine is communicated with surge tank by reduction valve, and on surge tank, outlet pipe and air brick bottom is connected, and is provided with wind speed detection device at the air brick top.
Described wind speed detection device is the wind gage with probe, and described probe is positioned at the ventilative side and corresponding with described outlet pipe of sewing on of air brick.
Be provided with the valve pressure table on reduction valve.The pressure limit of air compressor machine is 0.5～3MP.
Described air brick is positioned on support.
The utlity model has following advantage: it is simple in structure, easily makes or transformation, and operation is very easy, detects effectively and accurate, is beneficial to very much promotion and implementation.
Description of drawings
Fig. 1 is the scheme of installation of the utility model air brick Air permenbility measurement mechanism;
Fig. 2 is the A-A cross-sectional view of Fig. 1.
In figure, label 1 is air compressor machine, and 2 is reduction valve, and 3 is surge tank, and 4 is outlet pipe, and 5 is air brick, and 6 is wind gage, and 7 are the wind gage probe, and 8 are ventilative seam.
Embodiment
Embodiment 1: as depicted in figs. 1 and 2, air brick Air permenbility measurement mechanism comprises air compressor machine 1, reduction valve 2, surge tank 3 and wind gage 6.The output terminal of air compressor machine 1 is communicated with surge tank 3 by reduction valve 2, is provided with the valve pressure table simultaneously on reduction valve 3.On surge tank 3, outlet pipe 4 is connected with air brick 5 bottoms, is provided with wind speed detection device at air brick 5 tops.Described wind speed detection device is the wind gage 6 with probe 7, and described probe 7 is positioned at the ventilative seam of air brick 8 upsides and corresponding with described outlet pipe.
The probe 7 of wind gage is the tinsel of a velamen current flow heats, and mobile air makes its heat radiation, utilizes the square root of rate of heat dispation and wind speed linear, then by electronic circuit linearization (so that scale and reading), namely can be made into hot wire anemometer.Hot wire anemometer divides two kinds of heater-type and directly-heated types.The hot line of heater-type is generally manganese-copper filament, and its temperature-coefficient of electrical resistance is bordering on zero, and its surface separately is equipped with temperature element.Heaterless hot line mostly is platinum filament, can directly measure the temperature of hot line itself in measuring wind.Hot wire anemometer sensitivity when little wind speed is higher, is applicable to little measuring wind speed.Its time constant only has a few percent second, is the important tool that atmospheric turbulence and agricultural weather are measured.
Air compressor machine specify blow gas pressure (0.5～3MP), with the wind speed that the anemoscope multimetering blows out, draw mean value V, multiply by ventilative seam number with V, then multiply by to blow afloat and stitch thickness and width can draw Air permenbility.Flow=ventilative seam cross-sectional area S * wind speed V * bleeder vent quantity n.
Embodiment 2: content is substantially the same manner as Example 1, something in common does not repeat, different is: scheme as a supplement, can also increase a fan housing on embodiment 1 basis, through hole is set on fan housing, the outlet pipe of surge tank and fan housing through hole are installed together, and air brick is positioned at fan housing, can also be provided with jacking block in fan housing.
Embodiment 3: content is substantially the same manner as Example 1, something in common does not repeat, and different is: air brick is positioned on support, and the support of air brick should be considered as the part of this device, the version of this support is various, and wherein a kind of form can adopt netted back up pad.
