Observation graduated scale is crossed, air force in deodorization air hose can immediately, be accurately read, to realize scene to air quantity in deodorization air hose
Adjusting, cost far below eddy currents, plug-in type gas flowmeter currently on the market, and it is more convenient read data on flows,
It is a quantum jump of built sewage treatment plant's deodorization air hose air quantity monitoring at present.
Description of the drawings
Fig. 1 is the front view of the present invention;
Fig. 2 is the schematic diagram of flange plate;
Fig. 3 is the schematic diagram of wind disk.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of visual air flow indicator, including flange plate 1, holder 2, cylinder 3, the blind flange
Plate 1 be fixed on 3 upper and lower ends of cylinder and with cylinder 3 concentrically, fixing axle 4, the fixing axle 4 is fixed on staving 2 by holder 2
The position of center, the fixing axle 4 pass through among bearing 5, and bearing is set on bearing block 5 can do up and down certainly along fixing axle
By rotating, the wind disk 6 is fixed on bearing block 5, to make wind disk 6 freely up and down be rotated around axis in cylinder 3, passes through wind disk
6 position intuitively can accurately read the size of air mass flow on graduated scale 7.Cylinder 3 uses transparent material, to find out
Position of the wind disk 6 in cylinder.The graduated scale is arranged on air mass flow indicator exterior clear cylinder, the quarter on graduated scale
Spending range and scale can customize according to design air flow value and caliber.It is also arranged with spring outside the fixing axle 4.
Further, as shown in Fig. 2, being equipped with Y type holders in the flange plate 1 of the transparent cylinder, fixing axle 4 is fixed on
On Y type holders, specifically, the upper end of the transparent cylinder is equipped with upper flange, and Y type holders are equipped in upper flange;Transparent cylinder
Lower end is equipped with lower flange, and Y type holders are equipped in lower flange;Upper flange Y type carriage centers are fixed in the upper end of fixing axle, and lower end is solid
Due to lower flange Y type carriage centers.
As shown in figure 3, the center of the wind disk is equipped with the mounting hole for installing bearing, it is radial around the mounting hole
Several strip-shaped holes are evenly distributed with, the outer ring of the wind disk is evenly distributed with multiple round holes, and the side of the strip-shaped hole is along wind disk
Radial setting, the width at strip-shaped hole Jin Feng disk center end is smaller, and the width at nearly wind disk outer ring end is larger.
Further, a side of strip-shaped hole is equipped with groove so that when gas passes through strip-shaped hole, pushes the rotation of wind disk.
When the visual air flow indicator of the present invention is mounted on vertical deodorization air hose, first by the wind in deodorization air hose
Adjustable valve door is closed, and wind disk is in bottom, air quantity 0 at this time.With the unlatching of air-quantity adjusting valve, foul smell is indicated from flow
When below device upwardly through wind disk, small sircle hole discharges a part of gas on wind disk, and a part of gas passes through the strip-shaped hole on wind disk
It is discharged, has the gradient on one side in strip-shaped hole, when gas passes through strip-shaped hole, push the rotation of wind disk, air quantity is bigger, and the speed of rotation is got over
Soon, wind disk hovering position is higher, and air quantity graduated scale is posted on air mass flow indicator staving surface, by graduation apparatus it can be seen that logical
Cross air hose air volume.After air-quantity adjusting valve is closed, wind disk can automatically revert to initial with the effect of its own gravity
Position.
Wherein the quantity in the pore size of round hole and hole, the bevel angle of strip-shaped hole, groove quantity, spring diameter are thick
Carefully, the weight of spring space density, length, Material Strength, frictional force size between axis and bearing block, wind disk will pass through
The many factors such as profession calculating, experiment determine the accurate principal element of air mass flow indicator;
Kong Kai great, quantity is more, and wind disk will be unable to rotation, rotation stops and the instruction air quantity that floats up and down, and Kong Kai little, quantity is few, wind disk
Will rotate into top cannot be read correctly flow.According to experiment, empirical data is that percent opening is within 8.8% to 35.18%.Wind disk
Thickness, bevel angle, groove quantity, pore size, quantity are the sizes by caliber, and air volume coordinates spring
Can, frictional force size between axis and bearing, what many factors such as weight of wind disk determined.To pass through complicated correlation computations and more
Secondary experiment is verified to determine.The 0-150m that the air quantity range of 150 calibers of Φ has3/ h, some 0-650m3/ h, though the size of caliber
It is so the same, but it is different to measure air force, this just need the quantity in hole, bevel angle, groove quantity, spring diameter,
Away from density, Material Strength, coordinate spring performance, frictional force size between axis and bearing, many factors such as weight of wind disk are adjusted
Section.
According to a particular embodiment of the invention, through testing and calculating, when deodorization air hose is Φ 150, caliber air quantity is ranging from
0-150m3When/h, percent opening 8.8%, wind disk weight is 67.65g ~ 69.7g;And air quantity ranging from 0-650m3When/h, open
Porosity is 35.18%, and wind disk weight is 20.1g ~ 22.39g.
Bevel angle is to determine an important factor for wind disk rotates speed with length, and the wind disk gradient is bigger, and length is longer, wind disk
Velocity of rotation is faster, on the contrary then slower, and the rotating speed of wind disk cannot be too fast, can not be too slow, causes between axis and bearing soon very much
Frictional force is big, and the abrasion of axis and bearing is too big, and service life is shorter, can not be too slow, too slow since wind disk its own gravity is former
Cause, air quantity, which is worked as from 0, increases to 60m3When/h, wind disk is still in 0 position, and when air quantity is more than 60m3Wind disk flies up suddenly when/h.
Through measuring and calculating, the gradient of wind disk cannot be too big, can not be too small, is typically in the range of 30 ° ~ 42 °, length can not be too long, does not surpass generally
The 28% of diameter is crossed, the speed of wind disk rotation is usually 2.5 seconds/circle, and calculating is needed to be obtained with experiment.
