[0024] The present invention provides a glass fine powder screening device. Compared with the prior art, the glass fine powder is added from the feed port 7 of the screening sealed chamber 5, and the reciprocating drive mechanism drives the screening sealed chamber 5 to vibrate reciprocatingly. The glass fine powder is screened by the screening sealed chamber 5 and moves from the feed port 7 to the discharge port along with the vibration of the screening sealed chamber 5. During the vibration of the screening sealed chamber 5, multiple control arms 12 and multiple groups of resonant elastic components work together. The control arms 12 form a constraint on the vibration direction of the screening sealed chamber 5 along the first direction, and the resonant elastic component provides a resonance effect along the second direction. Since the first direction is perpendicular to the second direction, the effect of strengthening the vibration is achieved through resonance. At the same time, multiple anti-vibration supports are fixed on the foundation 4 and provide longitudinal elastic buffering. The present invention provides a glass fine powder screening device, in which the glass fine powder completes a sealed screening operation in a screening sealed chamber 5. A balance support frame carrying the screening sealed chamber 5 realizes buffering through a plurality of vibration-proof supports fixed on a foundation 4, thereby reducing the vibration pollution of the screening sealed chamber 5.

The glass powder enters the upper chamber through the feed port 7, and in the state of vibration of the screening sealed chamber 5, part of the glass powder passes through the filter screen 6 and enters the lower chamber, and the glass powder that does not pass through the filter screen 6 is non-conforming glass powder, and moves to the first discharge port 8 with the vibration of the screening sealed chamber 5 for discharge. The glass powder in the lower chamber is conforming glass powder, and moves to the second discharge port 9 with the vibration of the screening sealed chamber 5 for discharge.

[0026] See also Figure 1 and Figure 2 A distribution plate 10 is provided in the upper chamber, and the distribution plate 10 is located below the feed port 7. The distribution plate 10 is used to spread the glass fine powder onto the filter screen 6. The glass fine powder first falls onto the distribution plate 10 through the feed port 7, and the vibration of the distribution plate 10 spreads the glass fine powder toward the periphery, so that the glass fine powder can be evenly spread on the filter screen 6, thereby increasing the screening area and improving the screening efficiency.

[0027] Preferably, the middle portion of the distribution plate 10 is provided with a raised area, and a peripheral guide surface is formed around the raised area, which is conducive to the outward diffusion of the glass fine powder.

[0028] The balancing support frame includes two supporting beams 1, which are arranged in parallel. Multiple anti-vibration supports are symmetrically arranged at the bottom of the two supporting beams 1. The multiple anti-vibration supports on the same supporting beam 1 are arranged at intervals along the length direction. The multiple anti-vibration supports form a uniform support buffer structure, which can effectively reduce the impact of vibration on the surrounding environment.

[0029] Specifically, the anti-vibration support includes a support column 2 and an anti-vibration spring 3. The lower end of the support column 2 is used to be fixed on the foundation 4; the anti-vibration spring 3 is arranged at the upper end of the support column 2, and the upper end of the anti-vibration spring 3 is connected to the lower end surface of the supporting beam 1, and the anti-vibration spring 3 provides a longitudinal buffer force for the balance support frame.

[0030] See also Figure 1 A plurality of first supports 13 are respectively arranged on both sides of the lower end surface of the screening sealing chamber 5 along the length direction, and a first elastic sleeve 14 is arranged in the first support 13; a plurality of second supports 15 are respectively arranged on both sides of the screening mounting frame 11 along the length direction, and a second elastic sleeve 16 is arranged in the second support 15; a plurality of third supports 17 are sequentially arranged in the length direction of the supporting beam 1, and a third elastic sleeve 18 is arranged in the second support 15; the upper end of the control arm 12 is flexibly hinged to the first support 13 through the first elastic sleeve 14, the lower end of the control arm 12 is flexibly hinged to the second support 15 through the second elastic sleeve 16, and the middle part of the control arm 12 is flexibly rotatably connected to the third support 17 through the third elastic sleeve 18.

[0031] The control arm 12 is hinged to the screening sealing chamber 5 and the screening mounting frame 11 through the first support 13 and the second support 15, and is rotatably connected to the supporting beam 1 through the second support 15. At the same time, corresponding elastic sleeves are arranged in each support to achieve flexible connection at each point, thereby buffering the vibration of the screening sealing chamber 5 and reducing the impact on the surrounding environment.

[0032] Specifically, each group of resonant elastic components includes a lower mounting beam, an upper mounting beam and a plurality of resonant springs 19. The lower mounting beam is arranged on the upper end surface of the screening mounting frame 11 along the width direction; the upper mounting beam is arranged on the lower end surface of the screening sealing chamber 5 along the width direction; the plurality of resonant springs 19 are arranged side by side along the width direction, and the plurality of resonant springs 19 are obliquely installed between the upper mounting beam and the lower mounting beam along the second direction. The plurality of resonant springs 19 can form a resonance superposition effect in the width direction, thereby improving the resonance effect and strengthening the vibration.

[0033] See also Figure 1The reciprocating drive mechanism includes a drive motor 20, a transmission assembly and a crank assembly. The drive motor 20 is installed on a balance support frame; the transmission assembly is installed on a screening mounting frame 11 and is connected to the driving end of the drive motor 20; the crank assembly is connected to the transmission assembly, and the drive motor 20 drives the crank assembly to move through the transmission assembly, so as to drive the screening sealing chamber 5 to vibrate reciprocatingly.

[0034] The symmetrical positions of the two supporting beams 1 of the balance support frame respectively form U-shaped grooves, and the two driving motors 20 are symmetrically installed in the two U-shaped grooves, which can make the spatial structure more compact. The driving motor 20 transmits power to the crank assembly through the transmission assembly, and the crank assembly forms a reciprocating motion trajectory, thereby driving the screening sealing chamber 5 to vibrate reciprocatingly.

[0035] Specifically, the transmission assembly includes a transmission wheel 21 and a transmission belt 22. The transmission wheel 21 is mounted on the screening mounting frame 11 through a rotating seat, and the crank assembly is eccentrically connected to the transmission wheel 21; the transmission belt 22 is wound around the transmission wheel 21 and the driving end of the driving motor 20. Among them, the transmission wheel 21 is a V-shaped wheel, and the transmission belt 22 is a V-shaped belt. Similarly, a driving wheel adapted to the V-shaped belt is also installed at the driving end of the driving motor 20.

[0036] Specifically, the crank assembly includes a crankshaft connecting rod 23, a drive box 24 and a wooden spring 26. One end of the crankshaft connecting rod 23 is eccentrically connected to the transmission wheel 21; the drive box 24 is installed on the screening sealing chamber 5, and a rubber elastic body 25 is arranged in the drive box 24. The elastic rubber body is a rectangular parallelepiped structure, which is filled in the drive box 24 to achieve reciprocating deformation. One end of the wooden spring 26 is connected to the end of the crankshaft connecting rod 23 away from the transmission wheel 21, and the other end of the wooden spring 26 penetrates the drive box 24 and is connected to the rubber elastic body 25. The wooden spring 26 has certain rigidity and elasticity. The wooden spring 26 is composed of multiple layers of wooden strips staggered or stacked and connected by multiple layers of elastic sheets with curvature, which is softer and lighter than a rigid spring. The wooden spring 26 is connected to the elastic rubber body, and has elasticity with each other, so that the screening sealing chamber 5 is driven to move back and forth through the elastic rubber body inside the drive box 24 to achieve a vibration effect.

[0037] The working process of the present invention is as follows: The driving motor 20 is connected to the crankshaft connecting rod through the transmission assembly to rotate, and the crankshaft connecting rod drives the wooden spring 26 to vibrate. The vibration of the wooden spring 26 causes the rubber elastic body 25 to reciprocate and deform, and is transmitted to the screening sealing chamber 5, so that it vibrates continuously. This vibration drives the resonance elastic component connected to the screening sealing chamber 5, and under the limitation of the first direction of the control arm 12, a telescopic reciprocating motion in a second direction perpendicular to the first direction is formed. At the same time, the rotation of the crankshaft connecting rod 23 also drives the resonance spring 19 connected to the screening mounting frame 11 to vibrate. The two work together to make the glass fine powder in the screening sealing chamber 5 move toward the discharge port in a parabola. Multiple groups of resonance elastic components act on the screening sealing chamber 5 in the same direction at the same time. Multiple groups of resonance elastic components resonate, and the vibration force of the screening sealing chamber 5 is strengthened, so that the force of throwing the glass fine powder up and forward is strengthened, and the efficiency of screening is improved. The screening mounting frame 11 connected to the lower part of the resonance spring 19 forms multiple sets of triangular connections through the connection between the control arm 12 and the resonance spring 19. When vibrating, the control arm 12 is made to reciprocate with the third support 17 as the center of the circle under the limit of the upper and lower ends of the control arm 12 hinged. The thrust of the resonance spring 19 makes the screening sealing chamber 5 move forward. When it reaches a certain distance, it is weakened by the gravity of the screening sealing chamber 5 itself and the elastic force of the resonance spring 19, and automatically returns to complete a cycle of movement. This cycle is consistent with the circular motion of the crankshaft connecting rod 23, and the entire device is in a dynamic balance state. The vibration of this process is transmitted to the balance support frame, and the lower anti-vibration support absorbs most of the vibration, which is finally transmitted to the foundation 4 to reduce the vibration impact on the surrounding environment.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
