Description

Technical Field

[0001] This utility model belongs to the field of glass kiln feeding technology, and in particular relates to a kiln feeding system. Background Technology

[0002] Currently, glass furnaces typically have two parallel support tracks on the feeding side. These tracks are used to place hoppers with long rods, which allows the hoppers containing optical glass raw materials to be fed into the furnace manually or mechanically for tipping and unloading.

[0003] However, the two support tracks are usually installed with support columns below the end near the kiln feed side, which occupies a large amount of effective space outside the kiln feed side, resulting in the material box for holding raw materials having to be placed far away. In other words, before adding materials, it is still necessary to manually shovel the raw materials from the far-away material box into the hopper near the kiln feed side. There is a risk of the raw materials falling when shoveling them into the hopper, which can easily lead to the waste of expensive materials such as optical glass raw materials. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a kiln feeding system that can reduce raw material waste.

[0005] The objective of this utility model is achieved through the following technical solution: A kiln feeding system, comprising: The track assembly has one end connected to the upper part of the kiln. The hopper has a cylindrical rod at the end furthest from the kiln for sliding along the track assembly and rotating about its own axis. The guide plate is fixedly connected to the kiln, and its upper end is located directly below the feed inlet of the kiln. The material bin is located directly below the feeding position of the hopper shovel, and one end is used to receive the raw materials falling from the guide plate.

[0006] The beneficial effects of adopting the above technical solution are as follows: the upper part of one end of the track assembly is connected to the upper part of the kiln, and the support column is no longer set below the end, so as to release a large amount of effective space outside the kiln feed side, thereby facilitating the setting of the material box; when the raw material in the material box is shoveled into the hopper, the material box is directly below the hopper and can receive the raw material that may fall. When the hopper is sent into the kiln and turned over to pour the material, the guide plate can also guide the raw material that may fall into the material box. Therefore, the kiln feeding system can reduce the waste of expensive materials such as optical glass raw materials.

[0007] Furthermore, the track assembly includes a first support roller and a second support roller for supporting the two ends of the cylindrical rod, both of which are horizontally arranged. The length direction of both the first support roller and the second support roller is perpendicular to the sliding direction of the cylindrical rod. The first support roller is connected to the upper part of the kiln.

[0008] The beneficial effects of adopting the above technical solution are as follows: the first support roller and the second support roller can provide support for the lower end of the cylindrical rod so that the cylindrical rod can slide on the first support roller and the second support roller.

[0009] Furthermore, the kiln feeding system includes a support frame structure, the upper part of which is fixedly connected to the upper part of the kiln, and the two ends of the first support roller are rotatably connected to the lower part of the support frame structure.

[0010] The beneficial effects of adopting the above technical solution are as follows: the first support roller is connected to the upper part of the kiln through a support frame structure.

[0011] Furthermore, the kiln feeding system includes a support column structure, with the two ends of the second support roller rotatably connected to the upper part of the support column structure.

[0012] The beneficial effect of adopting the above technical solution is that the second support roller is installed above the ground through the support column mechanism.

[0013] Furthermore, a first limiting roller is provided at the lower part of the support frame structure, and a second limiting roller is provided at the upper part of the support column. The lower ends of both the first and second limiting rollers contact the upper end of the cylindrical rod.

[0014] The beneficial effects of adopting the above technical solution are as follows: the first limiting roller and the second limiting roller can limit the upper end of the cylindrical rod, so that the cylindrical rod slides more stably and avoids tilting around the first support roller due to the gravity of the hopper end.

[0015] Furthermore, a tilting rod is vertically arranged on the cylindrical rod to drive the cylindrical rod to rotate around its own axis, and the tilting rod and the hopper are located on both sides of the first support roller; When the tilting rod contacts the first support roller, the hopper is fully fed into the kiln.

[0016] The beneficial effects of adopting the above technical solution are as follows: when the tilting rod moves with the cylindrical rod to contact the first support roller, it means that the hopper has been completely fed into the kiln. At this time, the tilting rod drives the cylindrical rod to rotate around its own axis, which can pour the raw material in the hopper into the kiln.

[0017] Furthermore, a first cooling channel for introducing cooling medium is provided inside the cylindrical rod, and the inlet and outlet ends of the first cooling channel are both located at the end of the cylindrical rod away from the hopper.

[0018] The beneficial effects of adopting the above technical solution are as follows: by circulating cooling medium into the first cooling channel, the cylindrical rod can be cooled to reduce the impact of high temperature in the kiln on the cylindrical rod and its tilting rod, thereby facilitating manual operation of the cylindrical rod or tilting rod.

[0019] Furthermore, a second cooling channel that connects to the first cooling channel is provided inside the flip rod.

[0020] The beneficial effects of adopting the above technical solution are: this setting allows for cooling of the flipping lever, which in turn facilitates manual operation of the flipping lever.

[0021] Furthermore, the guide plate can be detachably connected to the kiln.

[0022] The beneficial effect of adopting the above technical solution is that the guide plate can be removed for cleaning or maintenance. Furthermore, a movable component is provided at the lower end of the hopper.

[0023] The beneficial effects of adopting the above technical solution are: the material box can be moved using the moving component, thereby facilitating the movement of the material box to the raw material storage area to replenish the raw materials.

[0024] The beneficial effects of this utility model are as follows: One end of the track assembly is connected to the upper part of the kiln, eliminating the need for a support column below that end. This frees up a large amount of effective space outside the kiln's feed side, facilitating the placement of the feed hopper. When the raw material in the feed hopper is shoveled into the hopper, the feed hopper is directly below the hopper and can catch any material that may fall. Furthermore, when the hopper is fed into the kiln and tilted to unload, the guide plate can guide any material that may fall into the feed hopper. Therefore, this kiln feeding system can reduce the waste of expensive materials such as optical glass raw materials. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] The existing optical glass furnace feeding technology suffers from systemic defects such as unreasonable spatial layout, serious waste of raw materials due to "secondary transfer", and inability to recover spilled materials during the feeding process.

[0029] This utility model provides a kiln feeding system that is highly integrated, compact, and has functions such as spillage material recovery. Specifically, for example... Figure 1 As shown, it includes: The track assembly has one upper end connected to the upper part of the kiln 1; The hopper 2 has a cylindrical rod 7 at the end of the hopper 2 that is away from the kiln 1 for sliding along the track direction of the track assembly and rotating about its own axis. The guide plate 13 is fixedly connected to the kiln 1, and the upper end of the guide plate 13 is located directly below the feed inlet of the kiln 1. Material bin 11, with an open top, is located directly below the material feeding position of hopper 2 and one end is used to receive raw materials falling from guide plate 13.

[0030] Understandably, the upper part of one end of the track assembly is connected to the upper part of the kiln 1, instead of setting a support column below this end as in the traditional solution. This frees up a large amount of effective space outside the feeding side of the kiln 1, making it easier to set up the material box 11. This makes the material scooping position of the hopper 2 basically consistent with or very close to the long-term storage position of the raw material in the horizontal direction. That is, during operation, the raw material in the material box 11 can be easily scooped into the hopper 2 directly above it. When the raw material in the material box 11 is scooped into the hopper 2, the material box 11 is directly below the hopper 2 and can receive the raw material that may fall. When the hopper 2 is fed into the kiln 1 and turned over to pour the material, the guide plate 13 can also guide the raw material that may fall into the material box 11. Therefore, this kiln feeding system can reduce the waste of expensive materials such as optical glass raw materials.

[0031] In other words, the kiln feeding system achieves the shortest path connection from storage to feeding, thereby reducing spillage during transportation at the source; the kiln feeding system optimizes the external spatial layout of the feeding side of kiln 1, integrating raw material storage, transportation and feeding functions into a compact workstation; the kiln feeding system achieves a closed-loop material supply during the feeding process, and instantly recovers any unavoidable trace amounts of spilled raw materials during operation, in order to achieve near-zero waste.

[0032] It should be noted that the guide plate 13 is obliquely installed between the lower edge of the inlet of the kiln 1 and the upper edge of the material box 11, and is preferably made of a smooth stainless steel plate. The guide plate 13 forms an inclined backflow surface pointing from the inlet of the kiln 1 to the inside of the material box 11. Specifically, its higher end is connected to or close to the lower part of the inlet of the kiln 1, and its lower end extends to the upper part or inside of the opening of the material box 11. This arrangement is so that when the hopper 2 is pushed into the kiln 1 along the track assembly or when it is turned over and poured into the kiln 1, any raw material spilled from the hopper 2 will fall onto the inclined guide plate 13 and slide down the plate surface under the action of gravity, and finally return directly to the material box 11 below, so as to facilitate the realization of the material closed loop of "spillage and return".

[0033] In one embodiment, the track assembly includes a first support roller 5 and a second support roller 9 for supporting the two ends of the cylindrical rod 7, respectively. The first support roller 5 and the second support roller 9 are both horizontally arranged, and the length direction of the first support roller 5 and the second support roller 9 are both perpendicular to the sliding direction of the cylindrical rod 7. The first support roller 5 is connected to the upper part of the kiln 1.

[0034] Understandably, the first support roller 5 and the second support roller 9 can provide support for the lower end of the cylindrical rod 7 so that the cylindrical rod 7 can slide on the first support roller 5 and the second support roller 9.

[0035] In one embodiment, the kiln feeding system includes a support frame structure 3, the upper part of which is fixedly connected to the upper part of the kiln 1, and the two ends of the first support roller 5 are rotatably connected to the lower part of the support frame structure 3.

[0036] Understandably, the first support roller 5 is connected to the upper part of the kiln 1 via the support frame structure 3.

[0037] It should be noted that the support frame structure 3 can be a hanger, and the first support roller 5 is rigidly connected to the inherent sturdy steel frame of the kiln 1 body through the hanger; the support frame structure 3 can also be a pulley structure, and the first support roller 5 is movably suspended on the inherent sturdy steel frame of the kiln 1 body through the pulley structure.

[0038] In one embodiment, the kiln feeding system includes a support column structure 10, with the two ends of the second support roller 9 rotatably connected to the upper part of the support column structure 10; the support column structure 10 may consist of several support columns to support the second support roller 9.

[0039] Understandably, the second support roller 9 is mounted above the ground via a support column mechanism.

[0040] In one embodiment, a first limiting roller 4 is provided at the lower part of the support frame structure 3, and a second limiting roller 8 is provided at the upper part of the support column. The lower ends of the first limiting roller 4 and the second limiting roller 8 both contact the upper end of the cylindrical rod 7.

[0041] Understandably, the first limiting roller 4 and the second limiting roller 8 can limit the upper end of the cylindrical rod 7 so that the cylindrical rod 7 slides more stably and avoids it from rotating and tipping over around the first support roller 5 due to the gravity of the hopper 2.

[0042] It should be noted that, in order to prevent the cylindrical rod 7 from moving perpendicular to the track on the track assembly, limit structures are set on the support frame structure 3 and the support column structure 10 to restrict the movement of the cylindrical rod 7 perpendicular to the track.

[0043] In one embodiment, a tilting rod 6 is vertically arranged on the cylindrical rod 7 for driving the cylindrical rod 7 to rotate around its own axis, and the tilting rod 6 and the hopper 2 are located on both sides of the first support roller 5, respectively. When the flipping rod 6 contacts the first support roller 5, the hopper 2 is fully fed into the kiln 1.

[0044] It is understandable that when the tilting rod 6 moves with the cylindrical rod 7 to contact the first support roller 5, it means that the hopper 2 is completely fed into the kiln 1. At this time, the tilting rod 6 drives the cylindrical rod 7 to rotate around its own axis, which can pour the raw material in the hopper 2 into the kiln 1.

[0045] It should be noted that when the opening of hopper 2 faces directly upward, the extension direction of cylindrical rod 7 faces directly downward, so as to determine the opening orientation of hopper 2 based on the extension direction of cylindrical rod 7.

[0046] In one embodiment, the cylindrical rod 7 is provided with a first cooling channel for introducing coolant, and the inlet and outlet ends of the first cooling channel are both located at the end of the cylindrical rod 7 away from the hopper 2.

[0047] It is understandable that by circulating coolant into the first cooling channel, the cylindrical rod 7 can be cooled to reduce the impact of the high temperature inside the kiln 1 on the cylindrical rod 7 and the tilting rod 6 on it, thereby facilitating manual operation of the cylindrical rod 7 or the tilting rod 6.

[0048] In one embodiment, the flipping rod 6 is provided with a second cooling channel that connects to the first cooling channel, so as to cool the flipping rod 6 as well, thereby facilitating manual operation of the flipping rod 6.

[0049] In one embodiment, the guide plate 13 can be detachably connected to the kiln 1 via a hinge, slot, or bracket so that the guide plate 13 can be removed for cleaning or maintenance.

[0050] In one embodiment, a moving component 12 is provided at the lower end of the material bin 11, and the moving component 12 may be rollers installed at the four corners of the lower end of the material bin 11.

[0051] Understandably, the material bin 11 can be moved using the moving component 12, thereby facilitating the movement of the material bin 11 to the raw material storage area to replenish the raw materials.

[0052] The working process of this utility model is as follows: Push in the material box 11 filled with raw materials so that the material box 11 is located at the lower end of the guide plate 13 and directly below the material feeding position of the hopper 2; The raw materials are shoveled from the material box 11 into the material hopper 2; Press the opening button at the feed inlet of kiln 1 to open the furnace door; push the cylindrical rod 7 to smoothly push the fully loaded hopper 2 into the kiln 1 and to the predetermined feeding point; then rotate the flipping rod 6 around the axis of the cylindrical rod 7 to flip the hopper 2 around the axis of the cylindrical rod 7, thereby pouring the raw material into the molten pool. Rotate the flipping rod 6 in the opposite direction to reset the hopper 2, then pull out the kiln 1 to allow for the next feeding.
