Technical Field
[0001] This utility model relates to the field of glass production technology, specifically to a glass raw material screening and processing device. Background Technology
[0002] Glass raw material screening and processing equipment is a key piece of equipment used for raw material pretreatment in the glass production process. Its core function is to classify the raw materials by particle size, remove impurities and optimize their quality through mechanical screening technology, so as to provide raw materials that meet the standards for subsequent melting processes.
[0003] Chinese utility model patent CN218945742U discloses a high-efficiency screening and processing device for glass raw materials, comprising a water circulation mechanism, a water spraying mechanism, a stone conveying mechanism, and a stone screening mechanism. The stone screening mechanism includes a gyratory screen. The water spraying mechanism is located above the inlet of the gyratory screen. The gyratory screen has a first outlet and a second outlet. A fine sand recovery machine is located below the second outlet. The sandstone to be screened is transported to the hopper by a loader, and then transported to the gyratory screen by a feeder and conveyor belt for screening (mesh screen). A water sprayer is installed on the upper side of the gyratory screen to form a water washing screening process inside the gyratory screen. The screened material (finished sand) enters the fine sand recovery machine for filtration and is then collected in a qualified material trough. The sandstone is then hoisted by a grab bucket and stored in a discharge silo, thereby filtering out sandstone with unqualified particle size.

[0024] Specifically, the two ends of the bidirectional lead screw 9 are connected to the left and right sides of the inside of the mounting box 3 respectively via ball bearings.
[0025] Specifically, the bidirectional lead screw 9 is connected to the first slider 14 and the second slider 7 respectively via lead screw threads. The top rear ends of the first slider 14 and the second slider 7 are provided with sliding grooves near the left and right sides. The sliding groove on the first slider 14 is movably sleeved with the sliding rod 8. The sliding groove on the second slider 7 is movably sleeved with the outer surface of the two sliding rods 8 near the bottom. The left and right ends of the two sliding rods 8 are fixedly connected to the inner left and right side walls of the mounting box 3 respectively.

[0027] In this implementation plan,
[0028] Specifically, the front wall of the main body 1 of the screening device is provided with a first connecting groove 15, and the rear wall of the mounting box 3 is provided with a second connecting groove 16. The first connecting groove 15 and the second connecting groove 16 are connected. The rear ends of the first slider 14 and the second slider 7 pass through the second connecting groove 16 and the first connecting groove 15 respectively and extend into the interior of the first connecting groove 15. Sealing blocks are fixedly installed at the top and bottom of the first connecting groove 15 and the second connecting groove 16, and the adjacent ends of the two sealing blocks are respectively attached to the opposite ends of the two first sliders 14 and the second slider 7.
[0029] In this implementation plan, glass raw materials are prevented from entering the mounting box 3.
[0030] Specifically, both the first filter plate 5 and the second filter plate 6 are located inside the main body 1 of the screening device, with the first filter plate 5 located above the second filter plate 6.
[0031] In this implementation plan,
[0032] Specifically, the top of the worm gear 11 penetrates the inner top wall of the mounting box 3 and extends to the top of the mounting box 3. The connection between the worm gear 11 and the mounting box 3 is made by ball bearings. Multiple threaded grooves 19 are distributed in a circular pattern on the outer surface of the worm gear 11 near the top. A limiting hole is opened on the top of the limiting block 18. A threaded rod 17 is inserted into the limiting hole on the limiting block 18. In use, the bottom of the threaded rod 17 penetrates the limiting hole and extends into the corresponding threaded groove 19. The threaded rod 17 is threadedly connected to the threaded groove 19.
[0033] In this implementation plan,
[0034] Specifically, the main body 1 of the screening device is equipped with a controller and a screening drive device, and the worm 11 and the worm wheel 10 mesh with each other.
[0035] In this implementation plan,
[0036] In use, unscrew and remove the threaded rod 17 from the limiting hole on the limiting block 18 and the threaded groove 19 on the top of the mounting box 3; this operation releases the limiting of the worm gear 11, preparing for subsequent adjustment of the filter screen position; then, hold the crank handle 13 and turn it clockwise or counterclockwise; the rotation of the crank handle 13 will drive the worm gear 11 to rotate together. Since the worm gear 11 and the worm wheel 10 mesh with each other, the worm wheel 10 rotates around the axis of the bidirectional lead screw 9, thereby driving the bidirectional lead screw 9 to rotate; the two ends of the bidirectional lead screw 9 are connected to the left and right side walls of the mounting box 3 through ball bearings to ensure its stable rotation; a first slider 14 is provided on the left side of the outer surface of the bidirectional lead screw 9. A second slider 7 is provided on the right side, and a bidirectional lead screw 9 is connected to the first slider 14 and the second slider 7 via a lead screw thread. When the bidirectional lead screw 9 rotates, the first slider 14 and the second slider 7 move in opposite or the same direction along the slide rod 8 under the action of the lead screw thread. The left and right ends of the slide rod 8 are fixedly connected to the left and right side walls inside the mounting box 3, respectively. The slide rod 8 is inserted into the sliding grooves at the top rear ends of the first slider 14 and the second slider 7, serving to guide and stabilize the movement of the sliders. A first filter screen 5 is fixedly installed at the rear end of the first slider 14, and a second filter screen 6 is fixedly installed at the rear end of the second slider 7. As the first slider 14 and the second slider 7 move... The first filter plate 5 and the second filter plate 6 move crosswise to adjust the screening gap between them. The first filter plate 5 is located above the second filter plate 6. By adjusting the screening gap, precise screening of glass raw materials of different particle sizes can be achieved to meet different production needs. After adjusting to the required filter plate aperture, the threaded rod 17 is reinserted into the limiting hole on the limiting block 18 and extends into the threaded groove 19 at the top of the mounting box 3. The threaded rod 17 is threadedly connected to the threaded groove 19, thereby strengthening the limiting effect of the limiting block 18 on the worm gear 11 and preventing the worm gear 11 from shifting position due to vibration or other factors during subsequent screening, ensuring... The device operates normally and maintains stable screening accuracy. The glass raw material to be screened is evenly fed into the main body 1 of the screening device through the feed end 2. Under gravity, the raw material falls sequentially onto the first filter plate 5 and the second filter plate 6. As the screening drive device on the main body 1 vibrates, the glass raw material is screened on the filter plates. Raw materials of different particle sizes pass through the corresponding filter plates according to the size of the screening gap. Smaller particle sizes pass sequentially through the first filter plate 5 and the second filter plate 6 and are discharged from the bottom discharge end 4. Larger particle sizes remain on the upper filter plate and are discharged from the corresponding discharge end 4, thus achieving graded screening of the glass raw material.
[0037] In summary, this glass raw material screening and processing device, through the configuration of a crank handle 13, a worm gear 10, a worm 11, a bidirectional lead screw 9, a slide bar 8, a first slider 14, a second slider 7, a first filter screen 5, and a second filter screen 6, can achieve graded screening of glass raw materials by adjusting the aperture size, thereby improving screening efficiency. The cross-movement can expand the screening range, adapting to raw materials with different particle size distributions, reducing downtime for screen replacement, and lowering the risk of production interruption. The entire adjustment system works collaboratively to quickly adapt to different production needs, reduce equipment adjustment time, and improve production efficiency.
