[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1 As shown, this utility model provides a technical solution: a screening device for fused silica, comprising:
[0024] The housing 1 has a feed channel 2 at its top, a downwardly inclined second filter screen 6 inside the housing 1, a second discharge port 7 at a position corresponding to the second filter screen 6 on the side wall of the housing 1, a guide plate 5 located below the second filter screen 6 inside the housing 1, and a first discharge port 4 at a position corresponding to the guide plate 5 on the side wall of the housing 1.
[0025] The housing 1 contains an inclined plate 8 located above the second filter screen 6 and tilted downwards. A dispersion component 9 for stirring the molten silica is mounted on the inclined plate 8. An air suction plate 10 is located above the lower end of the inclined plate 8 on the upper side of the inner wall of the housing 1. Multiple air suction holes 101 are opened at the bottom of the air suction plate 10. A dust collection component 3 for drawing dust from the air suction plate 10 is located on the side wall of the housing 1. This design uses the dispersion component 9 to stir and disperse the molten silica falling from the feed channel 2 onto the inclined plate 8, preventing the molten silica from concentrating and dust from remaining within it. The dispersed molten silica moves downwards along the surface of the inclined plate 8. The dust collection component 3 supplies air to the air suction plate 10, and the air suction holes 101 generate suction to draw in the dust from the molten silica passing the lower end of the inclined plate 8, preventing dust from flying everywhere. This results in good dust removal efficiency, improves the screening environment for molten silica, and avoids the harm to workers caused by flying dust, demonstrating excellent performance.
[0026] Reference Figure 2 , Figure 3 and Figure 4The dispersion assembly 9 includes a dispersion motor 91 disposed at the bottom of the inclined plate 8, and a plurality of dispersion plates 92 located above the inclined plate 8 on the side wall of the output shaft of the dispersion motor 91. This design uses the operation of the dispersion motor 91 to drive the dispersion plates 92 to rotate and stir and disperse the molten quartz on the inclined plate 8.
[0027] Reference Figure 4 A triangular plate 921 extends from the top of the dispersion plate 92. This design uses the triangular plate 921 to prevent molten quartz residue from remaining on the dispersion plate 92.
[0028] Reference Figure 2 and Figure 3 The sidewall of the suction plate 10 is attached to the inner wall of the housing 1. A baffle 11 is provided on one side of the bottom of the suction plate 10. An air suction chamber 12 is formed between the sidewall of the baffle 11, the bottom of the suction plate 10, and the inner wall of the housing 1. The air suction chamber 12 is located above the lower end of the inclined plate 8. This design ensures concentrated air suction and enhances the dust collection effect through the air suction chamber 12.
[0029] Reference Figure 1 and Figure 2 The dust collection assembly 3 includes a support plate 36 disposed on the side wall of the housing 1, a collection box 32 disposed on the top of the support plate 36, a suction fan 33 disposed on the top of the collection box 32, a first filter screen 37 disposed inside the collection box 32 for filtering dust, and a suction pipe 31 disposed on the side wall of the collection box 32, penetrating the side wall of the housing 1 and inserted into the suction plate 10, with the suction pipe 31 located below the first filter screen 37. This design utilizes the suction fan 33 in the dust collection assembly 3 to supply air to the suction plate 10. The suction holes 101 generate suction to extract dust from the fused silica passing through the lower end of the inclined plate 8, preventing dust from flying everywhere, resulting in good dust removal efficiency, improving the screening environment of the fused silica, and preventing flying dust from harming the workers. The dust follows the suction air along the suction pipe 31 into the collection box 32, where it is retained by the first filter screen 37, completing the dust removal operation.
[0030] Reference Figure 2 and Figure 3 The collection box 32 has a dust guide plate 38 located below the first filter screen 37 and tilted downwards inside. A cleaning port 39 is provided on the side wall of the collection box 32 at a position corresponding to the dust guide plate 38. A sealing plate 34 is provided on the side wall of the housing 1 to seal the cleaning port 39. A groove is provided on the top of the support plate 36, and a collection box 35 is disposed inside the groove. This design seals the cleaning port 39 with the sealing plate 34; by removing the sealing plate 34, dust can flow out from the cleaning port 39 along the dust guide plate 38 and fall into the collection box 35, facilitating dust cleaning.
[0031] Reference Figure 2The high end of the guide plate 5 is located below the low end of the second filter screen 6, and the low end of the inclined plate 8 is located above the high end of the second filter screen 6. This improves the rationality of the design.
[0032] Reference Figures 1-4 As an embodiment of this utility model: when it is necessary to screen fused silica, the worker puts the fused silica into the feed channel 2, and the fused silica falls onto the inclined plate 8; the dispersing motor 91 in the dispersing component 9 drives the dispersing plate 92 to rotate and stir and disperse the fused silica on the inclined plate 8, so as to avoid the fused silica from concentrating and dust remaining in it. The dispersed fused silica moves downward along the surface of the inclined plate 8; the fused silica is screened under the action of the second filter screen 6, and the screened fused silica flows out from the second discharge port 7 and the first discharge port 4 respectively.
[0033] The suction fan 33 in the dust collection assembly 3 operates to supply air to the suction plate 10. The suction holes 101 generate suction to draw in the dust in the fused silica passing through the lower end of the inclined plate 8. The dust follows the suction and enters the collection box 32 along the suction pipe 31. Under the action of the first filter screen 37, the dust is retained inside the collection box 32, preventing the dust from flying around. The dust removal effect is good, the screening environment of fused silica is improved, and the flying dust is prevented from causing harm to the health of the workers. The effect of use is good.
[0034] When dust needs to be cleaned, the sealing plate 34 can be removed, allowing the dust to flow out from the cleaning port 39 along the dust guide plate 38 and fall into the collection box 35, facilitating dust cleaning and improving the practicality of this utility model.
