Description

Technical Field

[0001] The utility model relates to the technical field of high-purity fused quartz processing, in particular to a screening mechanism for high-purity fused quartz processing. Background Art

[0002] Quartz, a professional term in geology, generally refers to low-temperature quartz (α-quartz), which is the most widely distributed mineral in the quartz family. In a broad sense, quartz also includes high-temperature quartz (β-quartz), coesite, etc. The main component is SiO2, which is colorless and transparent, and often contains a small amount of impurities, and becomes translucent or opaque crystals with a hard texture. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the trigonal oxide mineral system. Quartz block, also known as silica, is mainly the raw material for the production of quartz sand, and is also the raw material for quartz refractory materials and sintering ferrosilicon. In order to ensure the quality of quartz slurry before melting, quartz needs to be filtered and screened to separate quartz particles of different sizes.

[0003] For example, the utility model with application number 202320282902.3 discloses a screening mechanism for processing high-purity molten quartz. The screening mechanism for processing high-purity molten quartz drives the cam to rotate through the No. 1 rotating shaft, so that the cam pushes the left end of the screening plate to shake up and down, and at the same time, the No. 3 rotating shaft is used to rotate the turntable, and the rotation of the turntable drives the guide plate to rotate. Because the guide plate is limited by the straight rod and the L-shaped rod, the guide plate can only move back and forth horizontally, thereby driving the straight rod and the L-shaped rod to move back and forth horizontally, and then driving the side plate to move back and forth horizontally. The horizontal reciprocating movement of the side plate drives the mounting frame and the screening plate to move back and forth horizontally, thereby shaking out the piles of quartz and achieving a better screening effect.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This screening mechanism for high-purity fused quartz processing uses a side plate to reciprocate to shake out the quartz to improve the screening effect. However, in the process of screening the quartz, fine quartz powder may cause blockage in the mesh. In the case of blockage, the quartz powder cannot continue to be screened and fall, which in turn affects the screening efficiency.

[0006] Therefore, a screening mechanism for high-purity fused quartz processing is designed to optimize the above-mentioned problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a screening mechanism for high-purity fused quartz processing to solve the related technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A screening mechanism for processing high-purity molten quartz comprises a shell, a screening disc is slidably installed inside the shell, anti-leakage rings are fixed on the top and bottom of the screening disc, a sleeve is evenly fixed on the outside of the screening disc, a limit frame is evenly arranged on the outside of the shell, a sliding rod is fixed on the inside of the limit frame, a spring 1 is symmetrically sleeved on the outside of the sliding rod, and one end of the spring 1 is fixedly connected to the two ends of the sleeve, rollers are evenly arranged in an annular shape on the bottom of the screening disc, a through opening is opened at the connection between the shell and the limit frame, a material containing disc is fixed inside the shell and below the screening disc, a lower hopper is fixed on one side of the shell, a motor is installed on the bottom of the shell, a rotating shaft is fixed on the output shaft of the motor, a swivel and a brush plate are evenly fixed on the outside of the rotating shaft, and a protrusion is evenly arranged in an annular shape on the top of the swivel.

[0010] Preferably, the bottom of the housing is evenly provided with damping tubes, the interior of the damping tubes is slidably mounted with T-shaped rods, the outer sides of the T-shaped rods are sleeved with springs 2, and the bottom of the T-shaped rods is fixed with a shock-absorbing seat.

[0011] Preferably, partitions are symmetrically fixed on the top of the rotating shaft and above the screening disc, and comb teeth are evenly arranged on the bottom of the partitions.

[0012] Preferably, a protective pad is fixed to the bottom of the shock absorbing seat, and the protective pad is a shock absorbing protective pad.

[0013] Preferably, a protective layer is provided on the outer side of the leak-proof ring, and the protective layer is a wear-resistant protective layer.

[0014] Preferably, the protrusions are all arc-shaped blocks, and the top of the material receiving tray is arranged as an inclined surface.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a screening mechanism for processing high-purity fused quartz. Through the coordinated use of a shell, a screening plate, a leak-proof ring, a sleeve, a limit frame, a slide bar, a spring 1, a through port, a material holding plate, a lower hopper, a rotating shaft, a rotating ring, a convex block 1, a convex block 2, a brush plate and a motor, the utility model can dredge the mesh of the screening plate while screening the powder on the screening plate, thereby improving the dredging rate of the mesh of the screening plate and then improving the screening rate, and no additional power source is required, thus saving cost expenditure, thereby improving the practicality of the screening mechanism for processing high-purity fused quartz.

[0017] Through the coordinated use of the damping tube, the T-shaped rod, the second spring and the shock-absorbing seat, the sieving plate inside the shell shakes up and down to sieve the quartz powder while driving the shell to move up and down, and then drives the damping tube at the bottom to slide up and down on the outside of the T-shaped rod. Under the elastic force of the second spring, the amplitude and vibration of the up and down shaking of the damping tube and the shell are weakened, thereby improving the shock-absorbing effect of the screening mechanism for high-purity fused quartz processing;

[0018] Through the coordinated use of partitions and comb teeth, the partition on the top rotates at the same time as the shaft rotates, and the comb teeth at the bottom of the partition rotate on the top of the screening disk at the same time, so that the quartz powder on the top of the screening disk is evenly spread, thereby accelerating the screening of the quartz powder. The rotation of the partition driven by the shaft is more energy-saving and environmentally friendly, meeting people's different usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] Embodiment 1

[0025] like Figure 1-Figure 3As shown, this embodiment provides a screening mechanism for processing high-purity fused quartz, including a shell 1, a screening disc 2 is slidably installed inside the shell 1, a leak-proof ring 3 is fixed to the top and bottom of the screening disc 2, a sleeve 4 is evenly fixed to the outside of the screening disc 2, a limit frame 5 is evenly arranged on the outside of the shell 1, a slide bar 6 is fixed inside the limit frame 5, a spring 7 is symmetrically sleeved on the outside of the slide bar 6, and one end of the spring 7 is fixedly connected to the two ends of the sleeve 4, and a roller 14 is evenly arranged on the bottom of the screening disc 2 in an annular shape. The connection between the housing 1 and the limit frame 5 is provided with a through opening 8, a material tray 9 is fixed inside the housing 1 and below the screening plate 2, a lower hopper 10 is fixed on one side of the housing 1, a motor 16 is installed at the bottom of the housing 1, a rotating shaft 11 is fixed to the output shaft of the motor 16, a rotating ring 12 and a brush plate 15 are evenly fixed to the outside of the rotating shaft 11, a convex block 13 is evenly arranged on the top of the rotating ring 12 in an annular shape, a damping tube 19 is evenly arranged at the bottom of the housing 1, and a T-shaped rod 20 is slidably installed inside the damping tube 19. A spring 21 is sleeved on the outside of the T-shaped rod 20, and a shock-absorbing seat 22 is fixed to the bottom of the T-shaped rod 20.

[0026] The quartz material is poured onto the screening disk 2 in the shell 1, and the motor 16 is started to drive the rotating shaft 11 to rotate, thereby driving the rotating ring 12 and the protrusion 13 to rotate, so that the protrusion 13 intermittently pushes the top roller 14 and the screening disk 2 to move up, and at the same time, the screening disk 2 drives the sleeve 4 to move up and squeezes the spring 17. Under the elastic force of the spring 17, when the protrusion 13 and the roller 14 are misaligned, the screening disk 2 falls downward and shakes up and down, accelerating the screening of the quartz powder on the screening disk 2. At the same time, the rotating shaft 11 drives the brush plate 15 to rotate to dredge the mesh at the bottom of the screening disk 2, and keeps the mesh of the screening disk 2 dredged so that the powder passes quickly. The screening disk 2 inside the shell 1 shakes up and down to screen the quartz powder while driving the shell 1 to move up and down, and then drives the damping tube 19 at the bottom to slide up and down on the outside of the T-bar 20. Under the elastic force of the spring 21, the amplitude and vibration of the damping tube 19 and the shell 1 shaking up and down are weakened.

[0027] Embodiment 2

[0028] In this embodiment, if Figure 1-Figure 3 As shown, a partition plate 17 is symmetrically fixed on the top of the rotating shaft 11 and above the screening disc 2, and comb teeth 18 are evenly arranged on the bottom of the partition plate 17.

[0029] When the rotating shaft 11 rotates, the partition plate 17 on the top rotates simultaneously, and the comb teeth 18 at the bottom of the partition plate 17 rotate on the top of the sieving plate 2 at the same time, so as to spread the quartz powder on the top of the sieving plate 2 evenly.

[0030] In this embodiment, a protective pad is fixed to the bottom of the shock absorbing seat 22, and the protective pad is a shock absorbing protective pad.

[0031] The shock-absorbing protective pad further enhances the shock-absorbing effect of the bottom of the shock-absorbing seat 22, thereby improving the overall stability.

[0032] In this embodiment, a protective layer is provided on the outer side of the anti-leakage ring 3, and the protective layer is a wear-resistant protective layer.

[0033] The provision of the protective wear-resistant layer increases the protective effect on the outer side of the leak-proof ring 3 and strengthens the sealing between the outer shell 1 .

[0034] In this embodiment, the protrusions 13 are all arc-shaped blocks, and the top of the material receiving tray 9 is configured as an inclined surface.

[0035] The arrangement of the arc-shaped protrusions makes it easier to lift the roller 14 and the screening plate 2 upward, making screening more efficient, and the inclined surface on the top of the material receiving plate 9 makes it easier for the screened material to be discharged to the lower hopper 10.
