Description

Technical Field

[0001] This utility model relates to the technical field of impurity removal from fused silica, and in particular to a fused silica screening device. Background Technology

[0002] Fused silica, an amorphous substance of silicon dioxide, possesses typical glass properties, with its atomic structure exhibiting a long-range disordered state. In industrial applications, fused silica has a wide range of uses, primarily in precision casting, providing an excellent base material for the molding of high-precision parts; in the glass and ceramics industry, it effectively improves product performance and quality; in the refractory materials field, it can withstand high-temperature environments, providing excellent thermal insulation and structural support; and in the electronics and electrical appliance industry, it is an indispensable key material in the manufacturing of many electronic components.

[0003] In the production process of fused silica, the screening process is crucial. However, the current practice of using vibrating screens for most fused silica screening operations has significant drawbacks. When a large amount of material accumulates on the screen, vibration alone is insufficient to quickly disperse the material and achieve efficient screening. Because the material cannot be dispersed quickly, much of it remains in a state of accumulation for an extended period, failing to pass through the screen in time. This results in an excessively long screening process and a significant reduction in screening efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to propose a fused silica screening device that can effectively improve screening efficiency, enable materials to disperse quickly and pass through the screen, reduce the screening time required per unit output, and make the production process more efficient and smooth.

[0006] To achieve the above objectives, this utility model proposes a fused silica screening device, comprising a support frame, two guiding mechanisms, a supporting mechanism, a screen disc, a crank-rocker mechanism, and a drive assembly.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] The fused silica screening device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the fused silica screening device of this utility model embodiment may include a bracket 10, two guiding mechanisms 20, a support mechanism 30, a sieve plate 40, a crank rocker mechanism 50, and a drive assembly 60.

[0021] Two guide mechanisms 20 are arranged side by side and inclined on the bracket 10, the support mechanism 30 is movably arranged on the two guide mechanisms 20, the screen plate 40 is arranged on the support mechanism 30, and one end of the screen plate 40 is provided with a discharge port 41.

[0022] The crank-rocker mechanism 50 is rotatably mounted on the bracket 10 and is pivotally connected to the support mechanism 30. The drive assembly 60 is mounted on the bracket 10 and is connected to the crank-rocker mechanism 50.

[0023] It should be noted that the inclined arrangement of the guide mechanism 20 described in this embodiment facilitates the reciprocating movement of the support mechanism 30 on the two guide mechanisms 20. It should also be specifically noted that the end of the guide mechanism 20 closest to the drive assembly 60 is higher than the other end.

[0024] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figure 1 and Figure 2 As shown, the guide mechanism 20 may include a tripod 21 and a wave guide rail 22, wherein the tripod 21 is inclinedly mounted on the support 10, and the wave guide rail 22 is integrally formed and connected to the tripod 21.

[0025] It should be noted that, in this embodiment, one of the edges of the tripod 21 faces upward, and the wave guide rail is set on the edge of the tripod 21 and integrally connected with it.

[0026] Furthermore, in one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the support mechanism 30 may include two sets of grooved wheels 31, a tray 32 and two sets of springs 33. The two sets of grooved wheels 31 are respectively rolled on the corresponding wave guide rails 22, and each set of grooved wheels 31 may include two grooved wheels distributed side by side.

[0027] The tray 32 is mounted on two sets of grooved wheels 31, and a discharge port 301 is provided at one end of the tray 32 near the discharge port 41. Two sets of springs 33 are respectively mounted on both sides of the tray 32. Each set of springs 33 may include two springs arranged side by side, and one end of the spring 33 is fixedly connected to the side wall of the tray 32 through a connecting block, and the other end of the spring 33 is fixedly connected to the side wall of the screen plate 40 through a connecting block.

[0028] Furthermore, in one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the crank-rocker mechanism 50 may include a drive shaft 51, a crank 52 and a rocker arm 53, wherein the drive shaft 51 is rotatably mounted on the bracket 10.

[0029] The crank 52 is fixedly mounted on one end of the drive shaft 51, and a drive rod 501 is provided on the end face of the crank 52 at an eccentric position.

[0030] One end of the rocker arm 53 is sleeved on the drive rod 501, and the other end of the rocker arm 53 is pivotally connected to the tray 32 via a pin. It should be noted that, in this embodiment, the other end of the rocker arm 53 is pivotally connected to the end of the tray 32 away from the discharge port 301 via a pin.

[0031] Furthermore, in one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the drive assembly 60 may include a drive mechanism 61 and a belt drive mechanism 62. The drive mechanism 61 is mounted on the bracket 10, and the output end of the drive mechanism 61 is connected to the drive shaft 51 via the belt drive mechanism 62. It should be noted that the drive mechanism 61 described in this embodiment may be a drive motor.

[0032] It should be noted that the belt drive mechanism 62 described in this embodiment may include two pulleys and a belt, one of which is fixedly mounted on the drive shaft 51, and the other pulley is mounted on the output end of the drive mechanism 61, with the belt mounted on both pulleys.

[0033] Specifically, when fused silica needs to be screened, the relevant personnel first need to pour the raw material into the screen tray 40. Then, the personnel can control the drive mechanism 61 to drive the belt drive mechanism 62 to drive the drive shaft 51 to rotate. The rotating drive shaft 51 drives the crank 52 to rotate synchronously. The rotating crank 52 pushes the tray 32 to move back and forth on the wave guide rail 22 through the rocker arm 53. The reciprocating movement of the tray 32 drives the screen tray 40 to move synchronously. The inertia generated by the reciprocating movement causes the fused silica accumulated on the screen tray 40 to disperse quickly.

[0034] Meanwhile, the reciprocating tray 32 drives the grooved wheel 31 to roll on the wave guide rail 22. At this time, the rolling grooved wheel 31 bumps the tray 32, which in turn causes the screen tray 40 to bounce up and down under the elastic potential energy of the spring 33, effectively accelerating the screening efficiency of fused silica. The qualified fused silica falls into the tray 32 through the screen holes of the screen tray 40 and is discharged through the discharge port 301. The fused silica filtered in the screen tray 40 is discharged through the discharge port 41.

[0035] In summary, the fused silica screening device of this utility model can effectively improve screening efficiency, enable materials to disperse quickly and pass through the screen, reduce the screening time required per unit output, and make the production process more efficient and smooth.
