Technical Field

[0001] The present invention relates to the technical field of substrate glass production, and particularly relates to an automatic discharging device for a charging tank of a substrate glass tank furnace. Background Art

[0002] The main raw materials of substrate glass include silica sand, alumina, boric acid, carbonate, and other auxiliary raw materials. The production of substrate glass is a complex and delicate process, and the main steps include raw material preparation, melting, forming, heat treatment, cutting and processing, and subsequent processing, etc.

[0003] When producing substrate glass, according to the production formula, different types and quantities of raw materials need to be weighed and uniformly mixed to ensure the dispersion and uniform distribution of the raw materials, and then the mixed raw materials are sent into the glass tank furnace for melting by a feeding mechanism.

[0004] Since these raw materials are mostly in the physical form of powders or fine particles, they are easily scattered in the air. In addition, the falling distance of the materials in the smelting furnace is relatively long, and dust is easily generated. The generation and diffusion of dust require additional control measures to prevent environmental impact and worker health problems, increasing the control difficulty and cost.

[0011] As a further solution of the present invention: A downward flanging bayonet is circumferentially welded on the outside of the pipe of the lower flange discharging pipe.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-6As shown in the figure, an automatic discharging device for a charging tank of a substrate glass tank furnace includes a stainless-steel charging bin 1 and an automatic discharging assembly. The top of the stainless-steel charging bin 1 is provided with an opening, and a charging bin discharging pipe 2 is fixedly connected to the opening position of the stainless-steel charging bin 1. The automatic discharging assembly includes a valve core ejecting rod 9, an upper flange discharging pipe 14, and a charging tank body 17. A fixed cross bar 20 is horizontally and fixedly arranged inside the charging bin discharging pipe 2. The valve core ejecting rod 9 is fixed at the middle position on the top of the fixed cross bar 20. The top height of the valve core ejecting rod 9 is higher than the top height of the charging bin discharging pipe 2. The bottom of the charging tank body 17 is funnel-shaped, and a conical valve core assembly 16 is arranged in a matching manner at the lower end inside the charging tank body 17. The conical valve core assembly 16 fits with the inner wall of the charging tank body 17. The valve core ejecting rod 9 is used to lift the conical valve core assembly 16 in the charging tank body 17. An opening is provided at the top of the charging tank body 17, and a handle-equipped lid 19 is provided at the opening end of the charging tank body 17. The setting of the handle-equipped lid 19 prevents raw materials from flying out of the opening at the top of the charging tank body 17 during discharging. A lower flange discharging pipe 3 is fixed at the top of the charging bin discharging pipe 2. Both the lower flange discharging pipe 3 and the upper flange discharging pipe 14 are composed of a material pipe with the same inner diameter and a flange. The material pipe is located on one side of the flange, and the inner diameter of the material pipe is aligned with the inner diameter of the corresponding flange. The material pipes of the lower flange discharging pipe 3 and the upper flange discharging pipe 14 are arranged opposite to each other. The upper flange discharging pipe 14 is symmetrically located directly above the lower flange discharging pipe 3. An elastic lifting assembly is arranged between the flange of the lower flange discharging pipe 3 and the flange of the upper flange discharging pipe 14. When the charging tank body 17 is placed on the top of the upper flange discharging pipe 14, the upper flange discharging pipe 14 can be lowered in height, so that the valve core ejecting rod 9 continuously lifts the conical valve core assembly 16 in the charging tank body 17, and a distance is generated between the conical valve core assembly 16 and the inner wall of the charging tank body 17. Thus, the raw materials in the charging tank body 17 will be automatically fed into the stainless-steel charging bin 1. A flexible dust-proof assembly is arranged between the material pipes of the lower flange discharging pipe 3 and the upper flange discharging pipe 14, so as to achieve that when the upper flange discharging pipe 14 descends, the dust-proof effect between the upper flange discharging pipe 14 and the lower flange discharging pipe 3 will not be affected. A rubber sealing pad 15 is arranged on the side of the upper flange discharging pipe 14 away from the lower flange discharging pipe 3. When the charging tank body 17 is placed on the top of the rubber sealing pad 15, sealing is achieved to prevent raw materials from flying out of the contact gap, thus affecting the anti-flying effect. No additional control measures are required for environmental management, reducing the control difficulty and cost.

[0029] In some specific implementation cases, such as Figure 2As shown in the figure, in order to facilitate the realization that when the material tank body 17 is placed on the top of the upper flange discharge pipe 14, the valve core ejector rod 9 can lift the conical valve core assembly 16 in the material tank body 17, the elastic lifting assembly includes a compression spring 6 and a guide rod 7. A plurality of guide rods 7 are circumferentially and fixedly distributed at the bottom of the flange of the upper flange discharge pipe 14. The bottoms of the guide rods 7 all penetrate through the lower flange discharge pipe 3 and are slidably connected to the lower flange discharge pipe 3. The guide rods 7 have a limiting effect, ensuring the parallel compression of the upper flange discharge pipe 14. A compression spring 6 is sleeved outside each guide rod 7. One end of the compression spring 6 is connected to the flange of the upper flange discharge pipe 14, and the other end is connected to the flange of the lower flange discharge pipe 3. The function of the compression spring 6 is that when the material tank body 17 leaves, it can drive the upper flange discharge pipe 14 to reset, facilitating the next feeding. A plurality of equi-height limit screws 8 are circumferentially distributed and arranged at the top of the flange of the lower flange discharge pipe 3. The limit screws 8 are all movably and cooperatively connected to the flange of the lower flange discharge pipe 3. The limit screws 8 limit the descending height of the upper flange discharge pipe 14, ensuring that the valve core ejector rod 9 can normally open the conical valve core assembly 16.

[0030] In some specific implementation schemes, such as Figure 4 As shown in the figure, in order to facilitate the realization that when the upper flange discharge pipe 14 moves, it does not affect the dust-proof property between the lower flange discharge pipe 3 and the upper flange discharge pipe 14, the flexible dust-proof assembly includes a lower clamp 10, a canvas tube 11 and an upper clamp 12. The lower clamp 10 and the upper clamp 12 are both composed of two semi-circular clamps. The two ends of the two semi-circular clamps are fastened with screws. One end of the canvas tube 11 is sleeved outside the pipe of the upper flange discharge pipe 14, and the other end is sleeved outside the pipe of the lower flange discharge pipe 3. The upper clamp 12 is sleeved outside the canvas tube 11 and the pipe of the upper flange discharge pipe 14 to fix the upper end of the canvas tube 11. The lower clamp 10 is sleeved outside the canvas tube 11 and the pipe of the lower flange discharge pipe 3 to fix the lower end of the canvas tube 11. When the gas containing particles passes through the canvas tube 11, the powder particles will be trapped by the canvas tube 11, and at the same time, the gas is allowed to pass through smoothly and enter the outside. While filtering out the powder, a part of the air flow can also be released, avoiding the situation that the internal air flow cannot be released and lifting the handle cover 19. The canvas tube 11 is connected to the pipes of the upper flange discharge pipe 14 and the lower flange discharge pipe 3 in a detachable manner, facilitating the replacement or cleaning of the canvas tube 11 in the later stage.

[0031] In some specific implementation schemes, such as Figure 4As shown in the figure, in order to facilitate enhancing the stability of the fixation of the canvas cylinder 11, a downward flanging bayonet 4 is circumferentially welded on the outer circumference of the pipeline of the lower flange discharge pipe 3. The upper clamp 12 is sleeved on the outer circumference of the pipeline of the upper flange discharge pipe 14 and is clamped with the upward flanging bayonet 13. The upward flanging bayonet 13 is circumferentially welded on the outer circumference of the pipeline of the upper flange discharge pipe 14. The lower clamp 10 is sleeved on the outer circumference of the pipeline of the lower flange discharge pipe 3 and is clamped with the downward flanging bayonet 4. When the upper clamp 12 and the lower clamp 10 fix the canvas cylinder 11, they are respectively clamped with the upward flanging bayonet 13 and the downward flanging bayonet 4, avoiding the upper clamp 12 or the lower clamp 10 from slipping when the upper flange discharge pipe 14 moves up and down, resulting in gaps at the connection parts at both ends of the canvas cylinder 11 and poor anti-dust flying effect. The settings of the upward flanging bayonet 13 and the downward flanging bayonet 4 not only enhance the fixation stability of the canvas cylinder 11 but also improve the dust-proof performance of the overall device.

[0032] In some specific implementation schemes, such as Figure 5 As shown in the figure, in order to facilitate dispersing the lumpy raw materials falling inside the tank body 17, a separation cone 21 is provided at the top of the fixed cross bar 20. The top of the separation cone 21 is a pointed part, and the materials falling on the top of the separation cone 21 are dispersed, avoiding the accumulation of the falling and caking raw materials in the silo discharge pipe 2 and causing blockage of the material discharge.

[0033] In some specific implementation schemes, such as Figure 1 As shown in the figure, in order to facilitate enhancing the load-bearing strength of the lower flange discharge pipe 3, a number of supporting legs 5 for support are distributed between the bottom of the lower flange discharge pipe 3 and the stainless steel silo 1, avoiding the lower flange discharge pipe 3 from tilting and being damaged due to the excessive weight of the raw materials in the tank body 17.

[0034] In some specific implementation schemes, in order to facilitate adjusting the final descending height of the upper flange discharge pipe 14, the lower half of each limit screw 8 is in the shape of a screw rod (not marked in the figure). The limit screws 8 are all threadedly connected with the lower flange discharge pipe 3. By screwing the limit screws 8, the relative height between the limit screws 8 and the lower flange discharge pipe 3 can be adjusted, and thus the final descending height of the upper flange discharge pipe 14 can be changed.

[0035] In some specific implementation schemes, such as Figure 1 As shown in the figure, in order to facilitate lifting the tank body 17, no less than three lifting lugs 18 are distributed on the outer wall of the tank body 17. Hooking the lifting lugs 18 with a steel wire rope and cooperating with a crane can move the tank body 17.

[0036] In order to facilitate the understanding of this solution embodiment by those skilled in the art, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0037] Hang the lifting lug 18 on the steel wire rope, and use the crane in cooperation with the steel wire rope to lift the tank body 17 and place it on the top of the rubber gasket 15. Due to the gravity of the tank body 17, the upper flange discharge pipe 14 moves downward, and the guide rod 7 slides relative to the flange of the lower flange discharge pipe 3. At the same time, the compression spring 6 deforms and compresses until the flange of the upper flange discharge pipe 14 abuts against the top of the limit screw 8. During the movement, the valve core ejector rod 9 continuously lifts the conical valve core assembly 16 in the tank body 17, and the raw materials in the tank body 17 will be automatically fed into the stainless steel bin 1. Since the rubber gasket 15 is provided at the top of the upper flange discharge pipe 14, the bottom of the tank body 17 fits with the rubber gasket 15 to achieve sealing. At the same time, a handle cover 19 is provided at the top of the tank body 17. When the glass raw materials in the tank body 17 are fed, dust will not fly out from the upper opening of the tank body 17 in large amounts to pollute the environment. And a canvas tube 11 is detachably connected between the upper flange discharge pipe 14 and the lower flange discharge pipe 3 through a lower clamp 10 and an upper clamp 12. The canvas tube 11 can filter the flying raw material particles inside it. By connecting in a detachable manner, the canvas tube 11 can be cleaned or replaced irregularly.

[0038] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and should not be considered as limiting the scope of implementation of the present invention. Any equal changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
