Next, in the intelligent control unit according to the present invention, the effective hydraulic area, bending, load and bending, and natural frequency of the tubular air spring part formed by lifting the screen module by inhaling air and lowering the screen module by exhausting air are as follows. is set

First, as shown in FIG. 14 , the size of the tubular air spring can be expressed as an effective point diameter at the height of the stroke center.

And, the effective water pressure area becomes the diameter connecting the center of R located in the inner space of the tubular air spring part, and is expressed as in Equation 1 below.

Here, A represents the effective water pressure area (cm ² ), and D represents the effective diameter (cm).

And, as shown in Fig. 14, the effective diameter D0 in the case of a solid line increases only by X, and becomes the effective diameter D1 in the case of a dotted line.

As the effective diameter of the tubular air spring part changes according to the expansion and contraction of the tubular air spring part, of course, the effective water pressure area also changes.

In a relatively small range of curvature, the relationship between the effective hydraulic area (A) and the curvature is approximately as shown in Equation 2 below.

( The compression part is +, and the stretch part is -.)

In the case of using a constant internal pressure regardless of the expansion and contraction of the tubular air spring, the load at each bending position is required by applying the internal pressure to the pressure receiving area of the bending position.

As an example, in the case of a tubular air spring part (model AS22401), the effective water pressure area at a position extended by 60 mm is 285 cm ² , so that when used at an internal pressure of 3 kg/cm ² , it becomes 285×3 = 855 kg.

Next, the relationship between the load and the bending of the tubular air spring is generally shown in Equation 3 below.

Here, _He0 represents the effective height of V ₀ /A ₀ (cm), V _o represents the internal space volume (cm ³ ) at the height of the stroke center, and p ₀ is the internal pressure at the height of the stroke center (kg/cm ³ ) ), and k represents a polytropic index.

And, the internal pressure change in the tubular air spring according to the present invention is an isothermal displacement for a static displacement, and an adiabatic change for a dynamic displacement.

Next, the natural frequency when the screen module is connected and the total mass (M=W/g) of the screen module itself when supporting the screen module is loaded is as shown in Equation 4 below

Here, g represents the gravitational acceleration of 980 cm/sec ² , and k _d represents the dynamic spring constant.

And, the lateral rigidity of the tubular air spring according to the present invention is influenced by the rigidity of the intermediate ring, coupling bolt, and rubber.

Therefore, when the internal pressure of the tubular air spring part is increased, the horizontal spring constant also has a characteristic of increasing compared to it.

Hereinafter, a specific operation process of a 1:1 field-customized amplitude control type vibrating screen device comprising a tubular air spring unit and an intelligent control unit according to the present invention will be described.

First, if the second step mode is selected among the step-by-step mode selection buttons through the switch button unit, an amplitude of 9 mm is set.

Next, under the control of the intelligent control unit, the key input signal input to the switch button unit is received, and the tubular air spring and the air compressor are driven to have an amplitude of 9 mm.

That is, as shown in FIG. 20, the tubular air spring unit is driven according to the control signal of the intelligent control unit, and the screen module is lifted by the expansion of the rubber tube by the air filled in the inner space.

The air compressor supplies air toward the tubular air spring part.

And, since the amplitude of 9 to 11 mm is related to the amount of air filled into the inner space of the tubular air spring, the intelligent control unit receives the sensing signal for the amount of air filled into the inner space of the tubular air spring from the Kalman vortex air flow sensor. If it corresponds to the air quantity set value corresponding to the amplitude of ~11mm, the air compressor is stopped.

In addition, as shown in FIG. 21, the tubular air spring is driven according to the control signal of the intelligent control unit, and the air filled in the inner space is sucked by the air suction pump, and at this time, the rubber tube is reduced to reduce the screen module. will come down

Next, the vibration generator is driven under the control of the intelligent controller to generate the force of vibration in the screen module.

Next, as shown in FIG. 22, as the amplitude is deformed according to the expansion and contraction of the rubber tube by the air transmitted from the tubular air spring unit in the screen module, the force of the vibration generated from the vibration generating unit is transmitted, Through the force of vibration and the inclined structure, the input aggregate is spread out and the aggregate is sorted by size.

Next, when there are many retinal force parts in the screen part of the screen module when visually confirmed, when the retinal force phenomenon occurs, the operation of the device is stopped by pressing the Stop button through the switch button part.

Finally, as shown in FIG. 23, the retina force piercing mode selection button among the switch buttons increases the effective water pressure area and effective diameter of the two-step mode by 1.4 times, and increases the amplitude to 11 mm, and the excitation force is 4% to 10% creates

At this time, when the retinal force part is pierced by the excitation force higher than the second step mode, the second step mode is selected among the step-by-step mode selection buttons of the switch button unit again to drive the device.
