Generally, in the glass production process, a material feeding trolley is used to feed the material silo, and under normal circumstances, a full silo can be maintained for one to two hours.

[0003] In the glass production process, the furnace needs to be in operation at all times to reduce production costs. Therefore, the material feeding trolley needs to be running continuously. However, the material feeding trolley is prone to failure after running for a long time. In order to ensure that the furnace continues to work, manual material removal is usually required. In order to meet the operational needs, a large number of people need to work in shifts, resulting in low work efficiency and the risk of insufficient raw material supply. Utility Model Content

[0004] The main purpose of this invention is to propose a mobile raw material feeding device and a glass furnace feeding platform, which aims to enable quick and convenient material feeding when the material feeding trolley malfunctions, thereby improving material supply efficiency and saving manpower.

[0005] To achieve the above objectives, the present invention proposes a mobile raw material feeding device, comprising: A mobile component is mounted on a furnace feeding platform and located on one side of the pedestrian path of the furnace feeding platform. The mobile component is equipped with a container for carrying raw materials. A sealing structure is disposed on the movable component and closes the outlet of the container section; The sealing structure includes a sealing plate and a limiting part. The sealing plate is rotatably closed to the outlet of the container. The sealing plate is provided with a first extension extending to the side near the pedestrian path.

[0006] In one embodiment, the limiting part is provided with a limiting plane, a portion of the limiting plane is directly opposite the outlet of the container part, and the portion of the cover plate away from the rotation center of the cover plate is stacked on the limiting plane.

[0007] In one embodiment, a connector is provided between the limiting part and the container part to restrict the rotation of the limiting part, thereby limiting the rotation of the cover plate after it carries the raw material.

[0008] In one embodiment, the first extension extends to a portion near the side of the pedestrian path and is provided with a first grip portion, and the second extension extends to a portion near the side of the pedestrian path and is provided with a second grip portion.

[0009] In one embodiment, the moving component includes a moving carrier, the container portion is disposed on the moving carrier, the moving carrier is provided with a first through-hole, and the outlet of the container portion passes through the first through-hole, so that the outlet of the container portion is located on the surface of the moving carrier in the direction of the furnace feeding platform.

[0010] In one embodiment, the mobile carrier is provided with a push handle, which is disposed on the side of the mobile carrier and is bent in a direction away from the container section and close to the side of the pedestrian path.

[0011] In one embodiment, the mobile carrier is further provided with a second through opening; Wherein, the first extension passes through the second through opening and is located on one side of the push grip; and / or, The second extension passes through the second through opening and is located on one side of the push grip.

[0012] In one embodiment, the container section includes a carrying container and a guide section. The carrying container is disposed on the mobile carrier, and the outlet of the carrying container is connected to the first through-hole. The guide section is inclined and connected to the side of the carrying container. The projection of the guide part onto the plane of the moving carrier is located on one side of the moving carrier.

[0013] In one embodiment, the carrier container is provided with a diagonal brace, and the diagonal brace is connected to the surface of the guide portion facing the moving carrier.

[0014] This utility model also proposes a glass furnace feeding platform, including a furnace feeding platform and the aforementioned mobile raw material feeding device; The furnace feeding platform is equipped with a guide rail located on one side of the pedestrian path. The moving component is mounted on the guide rail. The furnace feeding platform has a feed inlet. The moving component moves so that the outlet of the container is directly opposite the feed inlet.

[0015] The technical solution of this utility model involves setting a movable component on the furnace feeding platform. When the movable component moves to the raw material addition point, the worker controls the first extension to rotate and close the outlet of the container.

[0023] In the glass production process, the supply of raw materials is a key link to ensure stable production. Generally, in the glass production process, a material feeding trolley is used to feed the material silo, and under normal circumstances, a full silo can be maintained for one to two hours.

[0024] In the glass production process, the furnace needs to be in operation at all times to reduce production costs. Therefore, the material feeding trolley needs to be running continuously. However, the material feeding trolley is prone to failure after running for a long time. In order to ensure that the furnace continues to work, manual material removal is usually required. In order to meet the operational needs, a large number of people need to work in shifts, resulting in low work efficiency and the risk of insufficient raw material supply.

[0025] This utility model proposes a mobile raw material feeding device.

[0026] Please see Figure 1 In one embodiment of this utility model, the mobile raw material feeding device includes: The mobile component 40 is mounted on the furnace feeding platform and is located on one side of the pedestrian path of the furnace feeding platform. The mobile component 40 is equipped with a container 30 for carrying raw materials. A capping structure 50 is disposed on the movable component 40 and closes the outlet of the container section 30; The sealing structure 50 includes a sealing plate 53 and a limiting part 56. The sealing plate 53 is rotatably closed at the outlet of the container section 30. The sealing plate 53 is provided with a first extension 54 extending to the side near the pedestrian path. The outlet of the container section 30 is rotatably provided with a limiting part 56 that limits the sealing plate 53. The limiting part 56 extends to the side near the pedestrian path to form a second extension.

[0027] like Figure 1 As shown, the moving component 40 is disposed on the surface of the furnace feeding platform. The moving component 40 can move on the furnace feeding platform, thereby facilitating the handling of raw materials through the moving component 40.

[0028] Understandably, by placing the raw materials on the container section 30 and then moving them to the inlet of the furnace feeding platform via the moving component 40, the efficiency of workers in shoveling and feeding materials is greatly improved during emergency feeding.

[0029] Furthermore, a pedestrian path is set on the furnace feeding platform for workers to walk on the furnace feeding platform so that workers can push the moving component 40 on the furnace feeding platform to spread the material.

[0030] like Figure 2 As shown, the container section 30 includes a raw material inlet and a raw material outlet. The raw material inlet is used for raw materials to enter the container section 30, and the raw material outlet is used for the output of stored raw materials.

[0031] like Figure 3 As shown, the sealing structure 50 seals the raw material outlet of the container section 30.

[0032] It is understandable that by sealing the raw material outlet of the container section 30 with the capping structure 50, raw materials are added into the container section 30 through the raw material inlet, and the raw materials accumulate in the container section 30.

[0033] Furthermore, the raw material outlet of the container section 30 is rotatably connected to the cover plate 53. After the cover plate 53 is rotated to close the raw material outlet, the raw material entering through the raw material inlet can accumulate in the container section 30 and be supported by the cover plate 53. After the cover plate 53 is rotated to open the raw material outlet, the raw material located in the container section 30 is discharged through the raw material outlet.

[0034] The limiting part 56 is designed to restrict the sealing plate 53 when the sealing plate 53 rotates to close the raw material outlet, thereby preventing the sealing plate 53 from rotating due to the weight of the raw material when it is piled on the sealing plate 53, thus ensuring the stability of the raw material when the moving component 40 moves.

[0035] The first extension and the second extension facilitate the operation of the restrictor 56 and the cover plate 53 by the workers.

[0036] The technical solution of this utility model is to set a movable component 40 on the furnace feeding platform. When the movable component 40 moves to the raw material addition point, the worker controls the first extension 54 to rotate and close the outlet of the container section 30. Then, the worker controls the second extension to restrict the rotation of the cover plate 53, thereby facilitating the addition of raw materials to the container section 30. Then, the worker pushes the movable component 40 along the pedestrian path to the material drop port of the furnace feeding platform. The worker controls the second extension to rotate and release the restriction on the cover plate 53, so that the cover plate 53 rotates under the weight of the raw material, thereby facilitating the automatic falling of the raw material into the material drop port and completing the automatic feeding. Then, the worker pushes the movable component 40 to reset and repeats the movement, assisting in the manual feeding process in emergency situations, greatly improving the work efficiency of manual feeding in emergency situations.

[0037] In one embodiment, the limiting part 56 is provided with a limiting plane, a portion of which faces the outlet of the container part 30, and the portion of the cover plate 53 away from the rotation center of the cover plate 53 is stacked on the limiting plane 51.

[0038] like Figure 6 and Figure 7 As shown, in order to restrict the cover plate 53, the restricting part 56 is provided on the side of the cover plate 53 away from the container part 30.

[0039] It is understandable that when the raw material is inside the container section 30, the raw material is supported by the surface of the cover plate 53, and the limiting part 56 is provided to ensure that the cover plate 53 keeps the container section 30 closed while supporting the raw material.

[0040] To ensure the stability of the restriction of the cover plate 53 by the restriction part 56, a restriction plane 51 is provided on the surface of the restriction part 56 that contacts the cover plate 53.

[0041] Understandably, by making the surface of the limiting part 56 that contacts the cover plate 53 flat, the cover plate 53 can be supported stably, thereby ensuring support stability and improving the limiting effect.

[0042] It should be noted that the cover plate 53 needs to close the outlet of the container section 30. For this purpose, the cross-section of the cover plate 53 needs to be larger than the cross-sectional area of ​​the outlet of the container section 30. At the same time, the limiting part 56 of the cover plate 53 needs to rotate. The rotation of the cover plate 53 and the rotation of the limiting part 56 should not interfere with each other. The limiting part 56 also needs to be able to limit the cover plate 53 after the cover plate 53 rotates.

[0043] Thus, part of the limiting plane faces the outlet of the container section 30. When the limiting section 56 rotates and releases the restriction on the cover plate 53, the limiting plane 51 is vertical. At this time, the cover plate 53 is no longer restricted and can rotate under the weight of the raw material to complete the feeding.

[0044] In another embodiment, a bracket may be provided at the outlet of the container section 30, and a limiting part 56 may be rotatably connected to the bracket. The limiting part 56 is away from the outlet of the container section 30, so that when the sealing plate 53 is restricted by the limiting part 56, the sealing plate 53 can completely close the outlet of the container section 30.

[0045] In one embodiment, a connector is provided between the limiting part 56 and the container part 30 to limit the rotation of the limiting part 56, thereby limiting the rotation of the cover plate 53 after it carries the raw material.

[0046] It should be noted that when the raw material is inside the container section 30, the raw material is supported by the cover plate 53. The part of the cover plate 53 connected to the limiting plane is prone to rotation under the action of the raw material when it abuts against the limiting plane. This rotation causes the limiting part 56 to rotate, which in turn affects the stability of the cover plate 53 in sealing the outlet of the container section 30. Since glass production requires sand, if the cover plate 53 fails to seal the outlet of the container section 30, the sand will easily leak and affect the feeding.

[0047] Therefore, a connector is provided between the limiting part 56 and the container part 30 to restrict the rotation of the limiting part 56, so as to prevent the sealing plate 53 from rotating and causing the limiting part 56 to rotate when the sealing plate 53 is carrying raw materials, thereby affecting the sealing effect of the sealing plate 53.

[0048] The presence of the connector restricts the restriction of the limiting part 56, thereby preventing the cover plate 53 from being rotated by the raw material it carries.

[0049] In one embodiment, the connecting member is a torsion spring, thereby improving the anti-rotation effect of the limiting part 56, and the limiting part 56 can rotate when the second extension is driven to rotate under human force, and the torsion spring is twisted.

[0050] In one embodiment, the first extension 54 extends to the side near the pedestrian path and is provided with a first gripping part, and the second extension is located at the side near the pedestrian path and is provided with a second gripping part.

[0051] Understandably, when the moving component 40 moves to the inlet of the furnace feeding platform 10, the second gripping part is manually controlled to rotate, thereby driving the limiting part 56 to rotate and release the restriction on the cover plate 53, thus facilitating the rotation of the cover plate 53 and allowing the raw material to be discharged from the outlet of the container part 30.

[0052] When the moving component 40 is reset, the first gripping part is manually rotated, which in turn causes the first extension part to rotate, thereby driving the cover plate 53 to rotate and re-close the outlet of the container section 30. Then, the second gripping part is manually rotated, thereby driving the limiting part 56 to rotate, thereby limiting the cover plate 53 and facilitating the installation of raw materials in the container section 30.

[0053] Because the worker walks on the pedestrian path, and both the first grip and the second grip are close to one side of the pedestrian path, the worker can conveniently operate the first grip and the second grip simultaneously while pushing the moving component 40 along the pedestrian path, thus improving operating efficiency.

[0054] In one embodiment, the moving component 40 includes a moving carrier 41, a container 30 disposed on the moving carrier 41, a first through-hole provided on the moving carrier 41, and an outlet of the container 30 passing through the first through-hole, so that the outlet of the container 30 is located on the surface of the moving carrier 41 in the direction of the furnace feeding platform.

[0055] like Figure 4 and Figure 5 As shown, the moving carrier 41 is a carrier that carries the moving container 30. Multiple rollers are provided on the moving carrier 41 to facilitate the movement of the moving carrier 41 on the furnace feeding platform 10.

[0056] It should be noted that the container section 30 is disposed on the surface of the moving carrier 41. In order to facilitate the container section 30 to feed into the furnace feeding platform 10, the outlet of the container section 30 can be disposed on the side of the moving carrier 41 facing the furnace feeding platform 10.

[0057] Therefore, a first through-hole is provided on the mobile carrier 41, and the outlet of the container section 30 is provided through the first through-hole.

[0058] It is understandable that after the outlet of the container section 30 passes through the first through-hole, the container section 30 is connected to the mobile carrier 41, thereby fixing the container section 30 on the mobile carrier 41 and facilitating the feeding of the container section 30 to the furnace feeding platform.

[0059] The portion of the container 30 that passes through the first through opening is a barrier 52. The limiting part 56 and the cover plate 53 are both connected to the barrier 52. The barrier 52 reduces the diameter of the opening to facilitate centralized material discharge.

[0060] In one embodiment, the mobile carrier 41 is provided with a push handle 43, which is disposed on the side of the mobile carrier 41 and bends away from the container part 30 and close to the side of the pedestrian path.

[0061] like Figure 4 As shown, a push handle 43 is provided on the mobile carrier 41, and the push handle 43 is facing the side of the pedestrian path.

[0062] Understandably, when a worker is walking on the pedestrian path, the worker can push the handle 43 to drive the moving carrier 41 to move on the surface of the furnace feeding platform 10.

[0063] In another embodiment, a plurality of push handles 43 are provided on the mobile carrier 41, and the plurality of push handles 43 are respectively provided on both sides of the mobile carrier 41, and are all close to the pedestrian path.

[0064] Understandably, the multiple push handles 43 are designed to facilitate multiple people to push the mobile carrier 41 to move simultaneously.

[0065] In one embodiment, the mobile carrier 41 is further provided with a second through opening 42; The first extension 54 passes through the second through opening 42 and is located on one side of a push grip 43; and / or, The second extension is inserted through the second through opening 42 and is located on one side of a push handle 43.

[0066] like Figure 2 As shown, the second through-hole 42 is disposed on the mobile carrier 41, and the second through-hole 42 is disposed near the push handle 43 on one side.

[0067] Thus, the first extension 54 is inserted through the second through opening 42, and / or the second extension is inserted through the second through opening 42, and both the first extension 54 and the second extension are close to the side of the pedestrian path, so as to facilitate the operation when the worker pushes the mobile carrier to move.

[0068] The second through-hole 42 is provided for the passage of the first extension and / or the second extension, to prevent the first extension and the second extension from extending from the bottom side of the movable carrier 41.

[0069] In one embodiment, the container part 30 includes a carrying container 32 and a guide part 31. The carrying container 32 is disposed on the mobile carrier 41, and the outlet of the carrying container 32 is connected to the first through port. The guide part 31 is inclined and connected to the side of the carrying container 32. The projection of the guide unit 31 onto the plane of the moving carrier 41 is located on one side of the moving carrier 41.

[0070] like Figure 2 As shown, the supporting container 32 is hollow, and the inlet section of the supporting container 32 is larger than the outlet section of the supporting container 32.

[0071] Understandably, the enlarged inlet of the large-section bearing container 32 facilitates the entry of raw materials from the guide section 31 into the bearing container 32, enabling them to enter the bearing container 32 quickly and stably, thus improving feeding efficiency.

[0072] It is understandable that the inner wall of the carrying container 32 is inclined and tilted towards the outlet of the carrying container 32. This inclined slope facilitates the guidance of raw materials, while the reduced cross-section of the outlet of the carrying container 32 facilitates concentrated discharge and avoids the spillage at the edges caused by large-mouth discharge, which would affect the discharge quality.

[0073] Since most raw materials are directly fed into the carrier container 32, a guide section 31 is provided to enable rapid feeding. The guide section 31 directly guides the raw materials into the carrier container 32, eliminating the need to constantly align the raw materials with the inlet of the carrier container 32 and improving feeding efficiency.

[0074] It should be noted that during the process of adding raw materials, when the raw materials are added from the feed pipe 20 to the carrying container 32, the sandy raw materials tend to pile up on the furnace feed platform 10 when they fall onto the furnace feed platform 10, thereby affecting the movement path of the moving carrier 41 and causing the moving carrier 41 to be unable to move to the feeding position each time.

[0075] like Figure 2 As shown, the guide part 31 is inclined and extends inclinedly to the feeding point.

[0076] It is understandable that the projection of the guide part 31 is located on the surface of the furnace feeding platform 10. Therefore, even if the moving carrier 41 fails to stop at the predetermined position, the inclined guide part 31 can still quickly receive the raw material.

[0077] In one embodiment, the carrier container 32 is provided with a diagonal brace 33, and the diagonal brace 33 is connected to the surface of the guide portion 31 facing the moving carrier 41.

[0078] In order to ensure the stability of the guide section 31 during the process of guiding the raw materials, a diagonal brace 33 is provided on the moving carrier 41 and the diagonal brace 33 is connected to the guide section 31, thereby improving the stability of the transmission of the guide section 31.

[0079] This utility model also proposes a glass furnace feeding platform, which includes a furnace feeding platform 10 and a mobile raw material feeding device. The specific structure of the mobile raw material feeding device is as described in the above embodiments. Since this glass furnace feeding platform adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The furnace feeding platform 10 is equipped with a guide rail 11, which is located on one side of the pedestrian path. A moving component 40 is disposed on the guide rail 11. The furnace feeding platform 10 is provided with a feed inlet 12. The moving component 40 moves so that the outlet of the container section 30 is directly opposite the feed inlet 12.

[0080] like Figure 1 As shown, a guide rail 11 is provided on the furnace feeding platform, and the moving component 40 is connected to the guide rail 11.

[0081] Understandably, when a worker walks on a pedestrian path and pushes the moving component 40 to run, the direction of movement of the moving component 40 is fixed by the guide rail 11, which also facilitates the worker's control of the moving component 40 and improves the efficiency of the worker driving the moving component 40.

[0082] Preferably, there are two guide rails 11, which are arranged in parallel, and both guide rails 11 are connected to the moving component 40.

[0083] It is understandable that a feed inlet 12 is provided between the two guide rails 11 so that when the moving component 40 moves to a predetermined position, the outlet of the container section 30 can be directly opposite the feed inlet 12, thereby facilitating unloading.

[0084] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
