Description

Technical Field

[0001] This utility model relates to the field of sorting devices, and in particular to a mixed material guiding and sorting device. Background Technology

[0002] In the raw material melting stage of the ultra-clear glass production line, the various equipment in the raw material workshop that come into contact with the raw materials and mixtures are equipped with liners to reduce the mixing of iron oxide components during the production process. The long-term contact and friction between the mixture and the liners may cause some of the liners to fatigue and peel off. The fragments are sent to the kiln head silo along with the mixture by the conveyor belt, becoming a potential hazard for subsequent material blockage or jamming.

[0003] The commonly used method for separating and removing liner plates involves installing a baffle horizontally above the conveyor belt, maintaining a fixed gap between the baffle and the belt. During transport, the mixture is blocked by the baffle, forcing larger fragments to deflect to the outside of the baffle and fall into the waste bin, while qualified material continues to move forward. Although this process is simple, the baffle gap cannot be dynamically adjusted. If the size of the fragments changes or the thickness of the material layer increases, it is easy for some fragments to be missed. At the same time, the edges of the baffle are easily deformed by the impact of fragments, requiring frequent shutdowns for maintenance.

[0004] Existing technologies also include simple screen sorting methods. In this method, the screen is directly laid on the conveyor belt's discharge end, and the mixture jumps forward on the screen. Large fragments are caught in the screen openings, while qualified material passes through and continues to be conveyed. However, the screen is easily clogged by fine powder and moisture in the mixture, causing a rapid reduction in the screening area and a decrease in separation efficiency. Clogged screens require manual knocking or disassembly and cleaning, resulting in high labor intensity and downtime that directly impacts production cycle time.

[0005] In addition to the aforementioned defects, the existing device has two major shortcomings: First, it lacks an effective spreading function for the mixture, with the material layer being thicker in the middle and thinner on both sides, resulting in a small contact area and uneven premixing when the crushed glass is added; Second, the material selection is inappropriate, as ordinary iron baffles or screens are prone to rust in humid environments, and the rust mixed into the ultra-white glass raw material will significantly increase the iron oxide content, affecting the optical performance of the product. Utility Model Content

[0006] Therefore, there is a need to provide a mixed material guiding and sorting device to solve the problem of low separation efficiency and inability to completely intercept liner fragments in existing technologies.

[0007] To achieve the above objectives, this utility model provides a mixed material guiding and sorting device, including an inclined rod set at a certain angle to the conveying direction of the conveyor belt, with support rods connected to both ends of the inclined rod, the bottom ends of the support rods fixedly connected to a support surface, and multiple guide plates fixed below the area of ​​the inclined rod corresponding to the conveying mechanism, any two adjacent guide plates being parallel and having the same spacing; the line connecting the centers of gravity of the multiple guide plates is parallel to the inclined rod, and the surface of the guide plates is parallel to the conveying direction of the conveyor belt.

[0008] Furthermore, a gap is provided between the bottom of the guide plate and the upper surface of the conveyor belt.

[0009] Furthermore, the gap ranges from 30mm to 5mm.

[0010] Furthermore, it also includes a waste bin, which is located on one side of the conveyor belt. As the waste moves forward with the conveyor belt, it is guided by multiple guide plates to move outside the conveyor belt and fall into the waste bin.

[0011] Furthermore, the angle between the inclined rod and the conveying direction of the conveyor belt is within the range of 45°±5°.

[0012] Furthermore, it also includes an adapter, which is fixedly connected to the inclined rod; the adapter has multiple connecting holes along the vertical direction, and the guide plate adjusts the gap between itself and the conveyor belt by being fixedly connected to some of the connecting holes.

[0013] Furthermore, the spacing between any two of the aforementioned guide vanes is 112mm ± 2mm.

[0014] Furthermore, the guide plate has a certain thickness, ranging from 15mm ± 1mm; and / or the width of the guide plate ranges from 100mm ± 5mm; and / or the height of the guide plate ranges from 350mm ± 10mm.

[0015] Furthermore, the adapter is a triangular iron, the upper part of which is fixedly connected to the diagonal bar, and one side of which is parallel to the transmission direction of the conveyor belt and is used to be fixedly connected to the guide plate.

[0016] Furthermore, a quick-release structure is provided between the triangular iron and the guide plate.

[0017] Unlike existing technologies, the above-mentioned technical solution causes material blockage in the kiln head silo or jamming at the feeder inlet when the mixture is directly fed into the kiln head silo during the conveying process. By designing and installing the aforementioned guide and sorting device in the middle section of the original melting belt near the front end of the waste silo, the detached liner plates and other larger blocky debris are sorted by the guide plate and directly discharged into the waste silo. This avoids debris entering the kiln head silo and causing material blockage, thereby affecting the normal feeding of the melting process.

[0018] In addition, the mixture is relatively thick during the conveying process, and the surface area contact is small when mixed with broken glass. After the flow guiding and sorting device is installed, when the mixture passes through the flow guiding and sorting device, the part of the mixture above the bottom of the flow guiding plate will be separated to both sides by the flow guiding plate. To a certain extent, the mixture is spread out laterally, which increases the coverage area with broken glass and improves the premixing effect of broken glass and mixture.

[0040] Please see Figures 1 to 5 This embodiment provides a mixed material guiding and sorting device, including an inclined rod 20 set at a certain angle to the conveying direction of the conveyor belt 10. Support rods 30 are connected to both ends of the inclined rod 20, and the bottom ends of the support rods 30 are fixedly connected to a support surface. Multiple guide plates 40 are fixed below the area of ​​the inclined rod 20 corresponding to the conveying mechanism. Any two adjacent guide plates 40 are parallel and have the same spacing. The line connecting the centers of gravity of the multiple guide plates 40 is parallel to the inclined rod 20, and the surface of the guide plates 40 is parallel to the conveying direction of the conveyor belt 10. The guide plates 40 are rectangular plate structures with a certain thickness. With one side of the guide plate 40 facing the incoming material, the mixed material can pass between any two adjacent guide plates 40. The volume of any detached liner plate is larger than the spacing between the guide plates 40 and can be blocked by the guide plates 40. Preferably, the side of the guide plate 40 facing the incoming material has an arc surface or an inclined surface to facilitate guiding the liner plate to move outward. Preferably, the spacing between any two of the guide plates 40 is 112mm ± 2mm. This spacing is optimized based on the 1200mm wide belt and the guide plates 40, which can form a continuous interception surface and avoid the mixture from being too dense and reducing its throughput.

[0041] The connection between the diagonal rod 20 and the support rod 30, and the connection between the support rod 30 and the support surface, can adopt common practices for metal frames: two vertical square tubes (e.g., 40mm×40mm×2mm) serve as support rods 30, with a connecting plate (e.g., 120mm×120mm×8mm) at the bottom of the support rod 30, which is secured to the concrete floor with expansion bolts; the diagonal rod 20 can be made of square tube (e.g., 50mm×50mm×3mm), with both ends welded to the top of the support rod 30 to form a rigid "gate"-shaped bracket, which can withstand the lateral impact generated by the belt during operation. The surfaces of the diagonal rod 20 and the support rod 30 are powder-coated for rust prevention, meeting the requirements of the high-humidity environment of the glass raw material workshop. It should be noted that the diagonal rod 20 is not limited to having an inclined surface in its shape, but rather that the diagonal rod 20 is set at a certain angle relative to the conveying direction of the conveyor belt 10 in a top-view perspective, i.e., it is relatively inclined. Preferably, the inclined rod 20 and the support rod 30 can be connected by a quick-release structure. Specifically, slots are designed at both ends of the inclined rod 20, and a matching latching component is installed on the top of the support rod 30. The latching component consists of a flexible claw and a release button. In its natural state, the flexible claw opens outward, and its shape and size fit tightly against the slots at the ends of the inclined rod 20, firmly fixing the inclined rod 20 to the support rod 30. When it is necessary to remove the inclined rod 20, simply press the release button. The button will push the flexible claw inward, disengaging it from the slot, at which point the inclined rod 20 can be easily removed from the support rod 30. This structural design not only makes the connection between the inclined rod 20 and the support rod 30 stable and reliable, but also makes the disassembly and assembly process simple and quick, requiring no tools, thus improving the efficiency of installation and maintenance.

[0042] The guide plate 40 has a certain thickness, preferably in the range of 15mm ± 1mm; and / or the width of the guide plate 40 is in the range of 100mm ± 5mm; and / or the height of the guide plate 40 is in the range of 350mm ± 10mm. Its material can be high-density polyethylene sheet. The thickness ensures wear resistance and bending resistance; the width is suitable for independent operation of a single plate and also facilitates side-by-side installation; the height takes into account both interception height and belt space limitations.

[0043] The guide plate and the slant bar can be fixedly connected in the following four ways: 1. Bolt fixing: A threaded metal seat is welded to the back of the guide plate. M8 or M10 stainless steel countersunk bolts are passed through the elongated holes on the angle iron (adapter) to achieve height and angle adjustment; only a wrench is needed for assembly and disassembly. 2. Spring pin buckle: A pin seat is set on the back of the guide plate, and a spring pin is welded to the corresponding position on the angle iron. Pressing the pin quickly locks or releases the plate. 3. T-shaped knob quick release: A T-shaped groove is cut on the top of the guide plate, and a T-shaped knob bolt is installed on the angle iron. Rotating 90° loosens or locks the plate without tools, suitable for dusty environments to prevent thread jamming. 4. Slide groove insertion: The top of the guide plate is machined into a dovetail-shaped slider, and a matching dovetail groove is set on the angle iron. After horizontal insertion, it is locked by a side set screw, allowing for millimeter-level fine-tuning, suitable for precision installation requirements.

[0044] The working principle of this new type is as follows: when the liner fragments move forward with the conveyor belt 10, they are blocked by the guide plate 40 and slide outward along the obstruction slope formed by the combination of multiple guide plates 40, thus preventing them from entering the kiln head hopper; at the same time, the thicker mixture is spread out laterally under the action of the guide plate 40, the thickness of the material layer is reduced, the area of ​​crushed glass incorporation is increased, and the premixing effect is significantly improved.

[0045] In some embodiments, a gap is provided between the bottom of the guide plate 40 and the upper surface of the conveyor belt. Preferably, the bottom edge of the guide plate 40 maintains a gap of 30mm ± 5mm with the belt surface. This height can both intercept the above-mentioned liner fragments and allow the mixture on the conveyor belt 10 to pass smoothly, ensuring smooth feeding; the gap is adjustable within a range of ± 5mm to adapt to changes in material layer thickness and ensure throughput.

[0046] In some embodiments, a waste bin 50 is also included. The waste bin 50 is located on one side of the conveyor belt. As the waste moves forward with the conveyor belt, it is guided by multiple guide plates 40 to move outside the conveyor belt and fall into the waste bin 50. The waste bin 50 is located outside the belt and can be made of 3mm stainless steel sheet bent into an open rectangular box. The bottom of the waste bin 50 may be equipped with casters for easy movement. Liner fragments are guided directly into the bin by the guide plates 40 for easy collection and centralized processing.

[0047] In some embodiments, the angle between the inclined rod 20 and the conveyor belt's conveying direction is within the range of 45°±5°. This angle strikes a balance between interception efficiency and throughput: if the angle is too small, fragments are prone to rebounding back onto the belt; if it is too large, it increases lateral thrust, causing the belt to deviate. Preferably, arc-shaped elongated holes can be added at the connection points between the inclined rod 20 and the support rod 30 at both ends, allowing for ±5° fine-tuning of the angle using tightening bolts. This enables on-site adjustments to the sorting effect based on the fragment shape and flow rate.

[0048] In some embodiments, an adapter is also included, which is fixedly connected to the inclined rod 20. The adapter has multiple connecting holes along the vertical direction, and the guide plate 40 adjusts its gap with the conveyor belt 10 by being fixedly connected to several of these connecting holes. The adapter can be made of triangular iron 60 or U-shaped channel steel. Triangular iron 60 has good stability and strength, providing multiple connection points to fix the guide plate 40. The stability of the triangular structure also helps maintain the positional accuracy of the guide plate 40 during operation. The two flanges of the U-shaped channel steel provide sufficient space for installing bolts or clips, facilitating adjustment of the height and angle of the guide plate 40. Furthermore, its opening direction can be adjusted according to actual needs to adapt to different installation environments and operational requirements.

[0049] Preferably, the adapter is a triangular iron 60. The upper part of the triangular iron 60 is fixedly connected to the diagonal rod 20, and one side of the triangular iron 60 is parallel to the transmission direction of the conveyor belt and is used to fix it to the guide plate 40. The adapter directly uses a standard triangular iron 60 (50mm×50mm×5mm), which is low in cost and easy to procure. The top edge of the triangular iron 60 is fully welded to the diagonal rod 20 for a fixed connection. Furthermore, a quick-release structure is provided between the triangular iron 60 and the guide plate 40. The quick-release structure can be a spring pin with a socket welded to the back of the guide plate 40. Pressing the pin allows the guide plate 40 to be pulled out. Alternatively, a T-shaped knob bolt can be used, which can be loosened by 90° to release. This enables quick assembly and disassembly, reduces downtime for maintenance, and reduces procurement and processing costs by using standard parts.

[0050] In the process of producing ultra-clear glass, various equipment in the raw material workshop that come into contact with raw materials and mixtures are equipped with liners to reduce the mixing of iron oxide during production. Some liners may detach due to long-term wear, and during conveying, they may be directly fed into the kiln head hopper along with the mixture, causing hopper blockage or material jamming at the feeder inlet. By designing and installing the aforementioned guide and sorting device in the middle section of the original melting belt near the front end of the waste hopper, the detached liners and other larger debris are sorted by the guide plate and directly discharged into the waste hopper; this avoids debris entering the kiln head hopper and causing blockage, thus preventing disruption to normal melting and feeding.

[0051] In addition, the mixture is relatively thick during the conveying process, and the surface area contact is small when mixed with broken glass. After the flow guiding and sorting device is installed, when the mixture passes through the flow guiding and sorting device, the part of the mixture above the bottom of the flow guiding plate will be separated to both sides by the flow guiding plate. To a certain extent, the mixture is spread out laterally, which increases the coverage area with broken glass and improves the premixing effect of broken glass and mixture.

[0052] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
